                                                                    ------------

                           CONVERGENT NETWORKS, INC.

                           2000 Stock Incentive Plan

1.   Purpose
     -------

     The purpose of this 2000 Stock Incentive Plan (the "Plan") of Convergent
Networks, Inc., a Delaware corporation ("Convergent" or the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and performance-based incentives and thereby
better aligning the interests of such persons with those of the Company's
stockholders. Except where the context otherwise requires, the term "Company"
shall include any of the Company's present or future parent or subsidiary
corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code
of 1986, as amended, and any regulations promulgated thereunder (the "Code") and
any other business venture (including, without limitation, joint venture or
limited liability company) in which the Company has a significant interest, as
determined by the Board of Directors of the Company (the "Board").

2.   Eligibility
     -----------

     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.   Administration and Delegation.
     ------------------------------

     (a)   Administration by Board of Directors. The Plan will be administered
           ------------------------------------
by the Board. The Board shall have authority to grant Awards and to adopt, amend
and repeal such administrative rules, guidelines and practices relating to the
Plan as it shall deem advisable. The Board may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or any Award in the manner
and to the extent it shall deem expedient to carry the Plan into effect and it
shall be the sole and final judge of such expediency. All decisions by the Board
shall be made in the Board's sole discretion and shall be final and binding on
all persons having or claiming any interest in the Plan or in any Award. No
director or person acting pursuant to the authority delegated by the Board shall
be liable for any action or determination relating to or under the Plan made in
good faith.

     (b)   Appointment of Committees. To the extent permitted by applicable law,
           -------------------------
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean the Board or a Committee of the Board to the
extent that the Board's powers or authority under the Plan have been delegated
to such Committee.

4.   Stock Available for Awards.
     ---------------------------

     (a)   Number of Shares. Subject to adjustment under Section 8, Awards may
           ----------------
be made under the Plan for a number of shares of common stock, $0.00001 par
value per share, of the Company (the "Common Stock") equal to the sum of:

           (1)  10,000,000 shares of Common Stock (the "Initial Shares"); plus

           (2)  an annual increase to be added on the first day of each of the
                Company's fiscal years during the period beginning in fiscal
                year 2001 and ending on the second day of fiscal year 2010 equal
                to the lesser of (i) 15,000,000 shares of Common Stock, (ii) 4%
                of the outstanding shares on such date or (iii) an amount
                determined by the Board.

     If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part (including as
the result of shares of Common Stock subject to such Award being repurchased by
the Company at the original issuance price pursuant to a contractual repurchase
right) or results in any Common Stock not being issued, the unused Common Stock
covered by such Award shall again be available for the grant of Awards under the
Plan, subject, however, in the case of Incentive Stock Options, to any
limitations under the Code. Shares issued under the Plan may consist in whole or
in part of authorized but unissued shares or treasury shares.

     (b)  Per-Participant Limit. Subject to adjustment under Section 8, the
          ---------------------
maximum number of shares of Common Stock with respect to which Awards may be
granted to any Participant under the Plan shall be 1,000,000 shares per calendar
year. The per-Participant limit described in this Section 4(b) shall be
construed and applied consistently with Section 162(m) of the Code ("Section
162(m)").

5.   Stock Options.
     --------------

     (a)  General. The Board may grant options to purchase Common Stock (each,
          -------
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b)  Incentive Stock Options. An Option that the Board intends to be an
          -----------------------
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

                                      -2-

     (c)  Exercise Price. The Board shall establish the exercise price at the
          --------------
time each Option is granted and specify it in the applicable option agreement.

     (d)  Duration of Options. Each Option shall be exercisable at such times
          -------------------
and subject to such terms and conditions as the Board may specify in the
applicable option agreement.

     (e)  Exercise of Option. Options may be exercised by delivery to the
          ------------------
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise. Common Stock purchased upon the exercise of an
          ---------------------
Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price and any required tax
withholding or (ii) delivery by the Participant to the Company of a copy of
irrevocable and unconditional instructions to a creditworthy broker to deliver
promptly to the Company cash or a check sufficient to pay the exercise price and
any required tax withholding;

          (3)  if the Common Stock is registered under the Securities Exchange
Act of 1934 (the "Exchange Act"), by delivery of shares of Common Stock owned by
the Participant valued at their fair market value as determined by (or in a
manner approved by) the Board in good faith ("Fair Market Value"), provided (i)
such method of payment is then permitted under applicable law and (ii) such
Common Stock, if acquired directly from the Company was owned by the Participant
at least six months prior to such delivery;

          (4)  to the extent permitted by the Board, in its sole discretion by
(i) delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (ii) payment of such other lawful consideration as
the Board may determine; or

          (5)  by any combination of the above permitted forms of payment.

     (g)  Substitute Options. In connection with a merger or consolidation of an
          ------------------
entity with the Company or the acquisition by the Company of property or stock
of an entity, the Board may grant Options in substitution for any options or
other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in the other sections of this Section 5 or in Section 2.

6.   Restricted Stock.
     ----------------

     (a)  Grants. The Board may grant Awards entitling recipients to acquire
          ------
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b)  Terms and Conditions. The Board shall determine the terms and
          --------------------
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any.

     (c)  Stock Certificates. Any stock certificates issued in respect of a
          ------------------
Restricted Stock Award shall be registered in the name of the Participant and,
unless otherwise determined by the Board, deposited by the Participant, together
with a stock power endorsed in blank, with the Company (or its designee). At the
expiration of the applicable restriction periods, the Company (or such designee)
shall deliver the certificates no longer subject to such restrictions to the
Participant or if the Participant has died, to the beneficiary designated, in a
manner determined by the Board, by a Participant to receive amounts due or
exercise rights of the Participant in the event of the Participant's death (the
"Designated Beneficiary"). In the absence of an effective designation by a
Participant, Designated Beneficiary shall mean the Participant's estate.

7.   Other Stock-Based Awards
     ------------------------

     The board shall have the rights to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events.
     ----------------------------------------------------------------

     (a)  Changes in Capitalization. In the event of any stock split, reverse
          -------------------------
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan
(including the number set forth in Section 4(a)(2)(i)), (ii) the per-Participant
limit set forth in Section 4(b), (iii) the number and class of securities and
exercise price per share subject to each outstanding Option, (iv) the repurchase
price per share subject to each outstanding Restricted Stock Award, and (v) the
terms of each other outstanding Award shall be appropriately adjusted by the
Company (or substituted Awards may be made, if applicable) to the extent the
Board shall determine, in good faith, that such an adjustment (or substitution)
is necessary and appropriate. If this Section 8(a) applies and Section 8(c) also
applies to any event, Section 8(c) shall be applicable to such event, and this
Section 8(a) shall not be applicable.

                                      -4-

     (b)  Liquidation or Dissolution. In the event of a proposed liquidation or
          --------------------------
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all Options will (i) become exercisable in full as of
a specified time at least 10 business days prior to the effective date of such
liquidation or dissolution and (ii) terminate effective upon such liquidation or
dissolution, except to the extent exercised before such effective date. The
Board may specify the effect of a liquidation or dissolution on any Restricted
Stock Award or other Award granted under the Plan at the time of the grant of
such Award.

     (c)  Reorganization and Change in Control Events.
          -------------------------------------------

          (1)  Definitions
               -----------

               (a)  A "Reorganization Event" shall mean:

                         converted into or exchanged for the right to receive
                         cash, securities or other property; or

                         to the Business Combination).

          (2)  Effect on Options
               -----------------

               (a)  Reorganization Event.  Upon the occurrence of a
                    --------------------
                    Reorganization Event (regardless of whether such event also
                    constitutes a Change in Control Event), or the execution by
                    the Company of any agreement with respect to a
                    Reorganization Event (regardless of whether such event will
                    result in a Change in Control Event), the Board shall
                    provide that all outstanding Options shall be assumed, or
                    equivalent options shall be substituted, by the acquiring or
                    succeeding corporation (or an affiliate thereof); provided
                                                                      --------
                    that if such Reorganization Event also constitutes a Change
                    ----
                    in Control Event, except to the extent specifically provided
                    to the contrary in the instrument evidencing any Option or
                    any other agreement between a Participant and the Company,
                    unvested shares in an amount equal to thirty percent (30%)
                    of the number of shares originally subject to the Option,
                    or, if applicable, such lesser number of remaining unvested
                    shares, shall be vested upon the occurrence of such
                    Reorganization Event and the remaining unvested shares, if
                    any, shall continue to become vested in accordance with the
                    original vesting schedule set forth in such option except
                    ratably adjusted to account for the acceleration of the
                    shares pursuant to this subsection (a).

<PAGE>

                    For purposes hereof, an Option shall be considered to be
                    assumed if, following consummation of the Reorganization
                    Event, the Option confers the right to purchase, for each
                    share of Common Stock subject to the Option immediately
                    prior to the consummation of the Reorganization Event, the
                    consideration (whether cash, securities or other property)
                    received as a result of the Reorganization Event by holders
                    of Common Stock for each share of Common Stock held
                    immediately prior to the consummation of the Reorganization
                    Event (and if holders were offered a choice of
                    consideration, the type of consideration chosen by the
                    holders of a majority of the outstanding shares of Common
                    Stock); provided, however, that if the consideration
                    received as a result of the Reorganization Event is not
                    solely common stock of the acquiring or succeeding
                    corporation (or an affiliate thereof), the Company may, with
                    the consent of the acquiring or succeeding corporation,
                    provide for the consideration to be received upon the
                    exercise of Options to consist solely of common stock of the
                    acquiring or succeeding corporation (or an affiliate
                    thereof) equivalent in fair market value to the per share
                    consideration received by holders of outstanding shares of
                    Common Stock as a result of the Reorganization Event.

                         Notwithstanding the foregoing, if the acquiring or
                    succeeding corporation (or an affiliate thereof) does not
                    agree to assume, or substitute for, such Options, then the
                    Board shall, upon written notice to the Participants,
                    provide that all Options will become exercisable in full as
                    of a specified time prior to the Reorganization Event and
                    will terminate immediately prior to the consummation of such
                    Reorganization Event, except to the extent exercised by the
                    Participants before the consummation of such Reorganization
                    Event; provided, however, that in the event of a
                    Reorganization Event under the terms of which holders of
                    Common Stock will receive upon consummation thereof a cash
                    payment for each share of Common Stock surrendered pursuant
                    to such Reorganization Event (the "Acquisition Price"), then
                    the Board may instead provide that all outstanding Options
                    shall terminate upon consummation of such Reorganization
                    Event and that each Participant shall receive, in exchange
                    therefor, a cash payment equal to the amount (if any) by
                    which (A) the Acquisition Price multiplied by the number of
                    shares of Common Stock subject to such outstanding Options
                    (whether or not then exercisable), exceeds (B) the aggregate
                    exercise price of such Options. To the

                                      -8-
<PAGE>

                    extent all or any portion of an Option becomes exercisable
                    solely as a result of the first sentence of this paragraph,
                    upon exercise of such Option the Participant shall receive
                    shares subject to a right of repurchase by the Company or
                    its successor at the Option exercise price. Such repurchase
                    right (1) shall lapse at the same rate as the Option would
                    have become exercisable under its terms and (2) shall not
                    apply to any shares subject to the Option that were
                    exercisable under its terms without regard to the first
                    sentence of this paragraph.

               (b)  Change in Control Event that is not a Reorganization Event.
                    ----------------------------------------------------------
                    Upon the occurrence of a Change in Control Event that does
                    not also constitute a Reorganization Event, except to the
                    extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company, the vesting schedule
                    of such Option shall be accelerated in part so that unvested
                    shares in an amount equal to thirty percent (30%) of the
                    number of shares originally subject to the Option, or, if
                    applicable, such lesser number of remaining unvested shares,
                    shall be vested upon the occurrence of such Change in
                    Control Event and the remaining unvested shares, if any,
                    shall continue to become vested ratably in accordance with
                    the original vesting schedule set forth in such option.

          (3) Effect on Restricted Stock Awards
              ---------------------------------

              (a)  Reorganization Event that is not a Change in Control Event.
                   ----------------------------------------------------------
                   Upon the occurrence of a Reorganization Event that is not a
                   Change in Control Event, the repurchase and other rights of
                   the Company under each outstanding Restricted Stock Award
                   shall inure to the benefit of the Company's successor and
                   shall apply to the cash, securities or other property which
                   the Common Stock was converted into or exchanged for pursuant
                   to such Reorganization Event in the same manner and to the
                   same extent as they applied to the Common Stock subject to
                   such Restricted Stock Award.

              (b)  Change in Control Event. Upon the ocurrence of a Change in
                   -----------------------
                   Control Event (regardless of whether such event also
                   constitutes a Reorganization Event), except to the extent
                   specifically provided

                                      -9-
<PAGE>

                   to the contrary in the instrument evidencing any Restricted
                   Stock Award or any other agreement between a Participant and
                   the Company, the vesting schedule of all Restricted Stock
                   Awards shall be accelerated in part so that an amount equal
                   to thirty percent (30%) of the number of shares originally
                   subject to the Restricted Stock Award, or, if applicable,
                   such lesser number of remaining shares that are not then free
                   from conditions or restrictions, shall immediately become
                   free from conditions or restrictions. The remaining shares,
                   if any, shall continue to become free from conditions or
                   restrictions in accordance with the original schedule set
                   forth in such Restricted Stock Award but ratably adjusted
                   to account for the shares accelerated pursuant to this
                   subsection (b).

          (4) Limitations. Notwithstanding the foregoing provisions of this
              -----------
Section 8(c), if the Change in Control Event is intended to be accounted for as
a "pooling of interests" for financial accounting purposes, and if the
acceleration to be effected by the foregoing provisions of this Section 8(c)
would preclude accounting for the Change in Control Event as a "pooling of
interests" for financial accounting purposes, then no such acceleration shall
occur upon the Change in Control Event.

9.   General Provisions Applicable to Awards
     ---------------------------------------

     (a)  Transferability of Awards. Except as the Board may otherwise determine
          -------------------------
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b)  Documentation. Each Award shall be evidenced in such form (written,
          -------------
electronic or otherwise) as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

     (c)  Board Discretion. Except as otherwise provided by the Plan, each Award
          ----------------
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

                                      -10-
<PAGE>

     (d)  Termination of Status. The Board shall determine the effect on an
          ---------------------
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e)  Withholding. Each Participant shall pay to the Company, or make
          -----------
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, if the Common Stock is registered under the Exchange Act,
Participants may satisfy such tax obligations in whole or in part by delivery of
shares of Common Stock, including shares retained from the Award creating the
tax obligation, valued at their Fair Market Value; provided, however, that the
total tax withholding where stock is being used to satisfy such tax obligations
cannot exceed the Company's minimum statutory withholding obligations (based on
minimum statutory withholding rates for federal and state tax purposes,
including payroll taxes, that are applicable to such supplemental taxable
income). The Company may, to the extent permitted by law, deduct any such tax
obligations from any payment of any kind otherwise due to a Participant.

     (f)  Amendment of Award. The Board may amend, modify or terminate any
          ------------------
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock. The Company will not be obligated to
          -------------------------------
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h)  Acceleration. The Board may at any time provide that any Award shall
          ------------
become immediately exercisable in full or in part, free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

10.  Miscellaneous
     -------------

     (a)  No Right To Employment or Other Status. No person shall have any claim
          --------------------------------------
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a

                                      -11-
<PAGE>

Participant the right to continued employment or any other relationship with the
Company. The Company expressly reserves the right at any time to dismiss or
otherwise terminate its relationship with a Participant free from any liability
or claim under the Plan, except as expressly provided in the applicable Award.

     (b)  No Rights As Stockholder. Subject to the provisions of the applicable
          ------------------------
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c)  Effective Date and Term of Plan. The Plan shall become effective on
          -------------------------------
the date on which it is adopted by the Board, but no Award granted to a
Participant that is intended to comply with Section 162(m) shall become
exercisable, vested or realizable, as applicable to such Award, unless and until
the Plan has been approved by the Company's stockholders to the extent
stockholder approval is required by Section 162(m) in the manner required under
Section 162(m) (including the vote required under Section 162(m)). No Awards
shall be granted under the Plan after the completion of ten years from the
earlier of (i) the date on which the Plan was adopted by the Board or (ii) the
date the Plan was approved by the Company's stockholders, but Awards previously
granted may extend beyond that date.

     (d)  Amendment of Plan. The Board may amend, suspend or terminate the Plan
          -----------------
or any portion thereof at any time, provided that to the extent required by
Section 162(m), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,
realizable or vested, as applicable to such Award, unless and until such
amendment shall have been approved by the Company's stockholders as required by
Section 162(m) (including the vote required under Section 162(m)).

     (e)  Governing Law. The provisions of the Plan and all Awards made
          -------------
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.

                                                                    EXHIBIT 10.5

                           CONVERGENT NETWORKS, INC.

                       2000 EMPLOYEE STOCK PURCHASE PLAN

The purpose of this Plan is to provide eligible employees of Convergent
Networks, Inc. (the "Company") and certain of its subsidiaries with
opportunities to purchase shares of the Company's common stock, $.00001 par
value per share (the "Common Stock"), commencing on the Effective Date (as
defined below).  Five million (5,000,000) shares of Common Stock in the
aggregate have been approved for this purpose.  This Plan is intended to qualify
as an "employee stock purchase plan" as defined in Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated
thereunder, and shall be interpreted consistent therewith.

     1. Administration. The Plan will be administered by the Company's Board of
Directors (the "Board") or by a Committee appointed by the Board (the
"Committee"). The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

     2. Eligibility.  All employees of the Company, including Directors who are
employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code) designated by the Board or the Committee from time
to time (a "Designated Subsidiary"), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 9) to purchase Common
Stock under the Plan provided that:

          they are customarily employed by the Company or a Designated
     Subsidiary for more than 20 hours a

          (a)  week; and

          (b)  they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

     No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary.  For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in determining the stock ownership of an employee, and all
stock which the employee has a contractual right to purchase shall be treated as
stock owned by the employee.

     3. Offerings.  The Company will make one or more offerings ("Offerings") to
employees to purchase stock under this Plan.  Offerings will begin each April 1
and October 1, or the first business day thereafter (the "Offering Commencement
Dates").  Each Offering Commencement Date will begin a six month period (a "Plan
Period") during which payroll deductions will be made and held for the purchase
of Common Stock at the end of the Plan Period.  The Board or the Committee may,
at its discretion, choose a different Plan Period of six (6) months or less for
subsequent Offerings.  Notwithstanding anything to the

                                       1
<PAGE>

contrary, the first Plan Period shall begin on the date (the "Effective Date")
on which the Securities and Exchange Commission declares effective the
registration statement on Form S-1 for the initial public offering of the
Company's Common Stock (the "Registration Statement") and shall end on the last
business day on or before October 1, 2001.

     4. Participation.  An employee eligible on the Offering Commencement Date
of any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the employee's appropriate payroll
office at least 10 days prior to the applicable Offering Commencement Date.  The
form will authorize a regular payroll deduction from the Compensation received
by the employee during the Plan Period.  Unless an employee files a new form or
withdraws from the Plan, his deductions and purchases will continue at the same
rate for future Offerings under the Plan as long as the Plan remains in effect.
The term "Compensation" means the annual gross compensation reportable on the
employee's Federal Income Tax Withholding Statement.

     5.  Deductions.  The Company will maintain payroll deduction accounts for
all participating employees.  With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction in any dollar amount up to a
maximum of 10% of the Compensation he or she receives during the Plan Period or
such shorter period during which deductions from payroll are made.  Payroll
deductions may be at the rate of any whole number percentage (up to 10%) of
Compensation with any change in compensation during the Plan Period to result in
an automatic corresponding change in the dollar amount withheld.  The minimum
payroll deduction is such percentage of compensation as may be established from
time to time by the Board or the Committee.

     No employee may be granted an Option (as defined in Section 9) which
permits his rights to purchase Common Stock under this Plan and any other
employee stock purchase plan (as defined in Section 423(b) of the Code) of the
Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the
fair market value of such Common Stock (determined at the Offering Commencement
Date of the Plan Period) for each calendar year in which the Option is
outstanding at any time.

     6. Deduction Changes.  An employee may decrease or discontinue his payroll
deduction once during any Plan Period, by filing a new payroll deduction
authorization form.  However, an employee may not increase his payroll deduction
during a Plan Period.  If an employee elects to discontinue his payroll
deductions during a Plan Period, but does not elect to withdraw his funds
pursuant to Section 8 hereof, funds deducted prior to his election to
discontinue will be applied to the purchase of Common Stock on the Exercise Date
(as defined below).

                                       2
<PAGE>

     7. Interest.  Interest will not be paid on any employee accounts, except to
the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.

     8. Withdrawal of Funds.  An employee may at any time prior to the close of
business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering.  Partial withdrawals are not
permitted.  The employee may not begin participation again during the remainder
of the Plan Period.  The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee.

     9. Purchase of Shares.  On the Offering Commencement Date of each Plan
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, the largest number of whole shares of Common Stock of the Company
as does not exceed the number of shares determined by multiplying $2,083 by the
number of full months in the Offering Period and dividing the result by the
closing price (as defined below) on the Offering Commencement Date of such Plan
Period.

     The purchase price for each share purchased will be 85% of the closing
price of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price shall be less.  Such closing
price shall be (a) the closing price on any national securities exchange on
which the Common Stock is listed, (b) the closing price of the Common Stock on
the Nasdaq National Market or (c) the average of the closing bid and asked
prices in the over-the-counter-market, whichever is applicable, as published in
The Wall Street Journal; provided that, with respect to the first Plan Period,
the closing price on the Offering Commencement Date shall be the offering price
to the public set forth in the final prospectus included within the Registration
Statement.  If no sales of Common Stock were made on such a day, the price of
the Common Stock for purposes of clauses (a) and (b) above shall be the reported
price for the next preceding day on which sales were made.

     Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his accumulated
payroll deductions on such date will pay for, but not in excess of the maximum
number determined in the manner set forth above.

     Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period will be automatically refunded to the employee, except that any
balance which is less than the purchase price of one share of Common Stock will
be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.

     10. Issuance of Certificates.  Certificates representing shares of Common
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the

                                       3
<PAGE>

Company's sole discretion) in the name of a brokerage firm, bank or other
nominee holder designated by the employee. The Company may, in its sole
discretion and in compliance with applicable laws, authorize the use of book
entry registration of shares in lieu of issuing stock certificates.

     11. Rights on Retirement, Death or Termination of Employment.  In the event
of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law) or (b) in the absence of
such a designated beneficiary, to the executor or administrator of the
employee's estate or (c) if no such executor or administrator has been appointed
to the knowledge of the Company, to such other person(s) as the Company may, in
its discretion, designate.  If, prior to the last business day of the Plan
Period, the Designated Subsidiary by which an employee is employed shall cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan.

     12. Optionees Not Stockholders.  Neither the granting of an Option to an
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.

     13. Rights Not Transferable.  Rights under this Plan are not transferable
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

     14. Application of Funds.  All funds received or held by the Company under
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15. Adjustment in Case of Changes Affecting Common Stock.  In the event of
a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately, and
such other adjustment shall be made as may be deemed equitable by the Board or
the Committee.  In the event of any other change affecting the Common Stock,
such adjustment shall be made as may be deemed equitable by the Board or the
Committee to give proper effect to such event.

     16. Merger.  If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the capital stock of the surviving corporation ("Continuity
of Control"), the holder of each Option then outstanding will thereafter be
entitled to receive at the next Exercise Date upon the exercise of such Option
for each share as to which such Option shall be exercised the securities or
property which a holder of one share of the Common Stock was entitled to upon
and at the time of such merger or consolidation, and the Board or the Committee
shall take such steps in connection with such

                                       4
<PAGE>

merger or consolidation as the Board or the Committee shall deem necessary to
assure that the provisions of Section 15 shall thereafter be applicable, as
nearly as reasonably may be, in relation to the said securities or property as
to which such holder of such Option might thereafter be entitled to receive
thereunder.

Plan to the contrary:

          (a) Every eligible employee shall automatically become a participant
     in the Plan for the First Plan Period at the highest percentage of
     Compensation permitted under Section 5. No payroll deductions shall be
     required for the First Plan Period; however, a participant may, at any time
     after the effectiveness of the Plan's Registration Statement on Form S-8,
     elect to have payroll deductions up to the aggregate amount which would
     have been credited to his or her account if a deduction of ten percent
     (10%) of the Compensation which he or she received on each pay day during
     the First Plan Period had been made (the "Maximum Amount") or decline to
     participate by filing an appropriate subscription agreement.

          (b) Upon the automatic exercise of a participant's option on the
     Exercise Date for the First Plan Period, a participant shall be permitted
     to purchase shares with (i) the accumulated payroll deductions in his or
     her account, if any, (ii) a direct payment from the participant, or (iii) a
     combination thereof; provided, however that the total amount applied to the
     purchase may not exceed the Maximum Amount.

                             Adopted by the Board of Directors
                             on September 22, 2000
