                         Employee Stock Purchase Plan


SECTION 1.  PURPOSE OF THE PLAN.

          The Board adopted the Plan effective as of the date of the IPO.  The
purpose of the Plan is to provide Eligible Employees with an opportunity to
increase their proprietary interest in the success of the Company by purchasing
Stock from the Company on favorable terms and to pay for such purchases through
payroll deductions.  The Plan is intended to qualify under section 423 of the
Code.

SECTION 2.  ADMINISTRATION OF THE PLAN.

          (a) Committee Composition.  The Committee shall administer the Plan.
The Committee shall consist exclusively of one or more directors of the Company,
who shall be appointed by the Board.

          (b) Committee Responsibilities.  The Committee shall interpret the
Plan and make all other policy decisions relating to the operation of the Plan.
The Committee may adopt such rules, guidelines and forms as it deems appropriate
to implement the Plan.  The Committee's determinations under the Plan shall be
final and binding on all persons.

SECTION 3.  ENROLLMENT AND PARTICIPATION.

          (a) Offering Periods.  While the Plan is in effect, two overlapping
Offering Periods shall commence in each calendar year.  The Offering Periods
shall consist of the 24-month periods commencing on each February 1 and August
1, except that the first Offering Period shall commence on the date of the IPO
and end on July 31, 2002.

          (b) Accumulation Periods.  While the Plan is in effect, two
Accumulation Periods shall commence in each calendar year.  The Accumulation
Periods shall consist of the six-month periods commencing on each February 1 and
August 1, except that the first Accumulation Period shall commence on the date
of the IPO and end on July 31, 2002.

          (c) Enrollment.  Any individual who, on the day preceding the first
day of an Offering Period, qualifies as an Eligible Employee may elect to become
a Participant in the Plan for such Offering Period by executing the enrollment
form prescribed for this purpose by the Committee.  The enrollment form shall be
filed with the Company at the prescribed location not later than 10 business
days prior to the commencement of such Offering Period, except that the Company
may announce a deadline that is less than 10 business days prior to the
commencement of the first Offering Period.
<PAGE>

          (d)   Duration of Participation.  Once enrolled in the Plan, a
Participant shall continue to participate in the Plan until he or she ceases to
be an Eligible Employee, withdraws from the Plan under Section 5(a) or reaches
the end of the Accumulation Period in which his or her employee contributions
were discontinued under Section 4(d) or 8(b).  A Participant who discontinued
employee contributions under Section 4(d) or withdrew from the Plan under
Section 5(a) may again become a Participant, if he or she then is an Eligible
Employee, by following the procedure described in Subsection (c) above.  A
Participant whose employee contributions were discontinued automatically under
Section 8(b) shall automatically resume participation at the beginning of the
earliest Accumulation Period ending in the next calendar year, if he or she then
is an Eligible Employee.

          (e)   Applicable Offering Period.  For purposes of calculating the
Purchase Price under Section 7(b), the applicable Offering Period shall be
determined as follows:

          (i)   Once a Participant is enrolled in the Plan for an Offering
     Period, such Offering Period shall continue to apply to him or her until
     the earliest of (A) the end of such Offering Period, (B) the end of his or
     her participation under Subsection (d) above or (C) re-enrollment for a
     subsequent Offering Period under Paragraph (ii) or (iii) below.

          (ii)  In the event that the Fair Market Value of Stock on the last
     trading day before the commencement of the Offering Period for which the
     Participant is enrolled is higher than on the last trading day before the
     commencement of any subsequent Offering Period, the Participant shall
     automatically be re-enrolled for such subsequent Offering Period.

          (iii) Any other provision of the Plan notwithstanding, the Company (at
     its sole discretion) may determine prior to the commencement of any new
     Offering Period that all Participants shall be re-enrolled for such new
     Offering Period.

          (iv)  When a Participant reaches the end of an Offering Period but his
     or her participation is to continue, then such Participant shall
     automatically be re-enrolled for the Offering Period that commences
     immediately after the end of the prior Offering Period.

SECTION 4.  EMPLOYEE CONTRIBUTIONS.

          (a)   Frequency of Payroll Deductions.  A Participant may purchase
shares of Stock under the Plan solely by means of payroll deductions.  Payroll
deductions, as designated by the Participant pursuant to Subsection (b) below,
shall occur on each payday during participation in the Plan.

          (b)   Amount of Payroll Deductions.  An Eligible Employee shall
designate on the enrollment form the portion of his or her Compensation that he
or she elects to have withheld for the purchase of Stock.  Such portion shall be
a whole percentage of the Eligible Employee's Compensation, but not less than 1%
nor more than 15%.

                                       2
<PAGE>

          (c) Changing Withholding Rate.  If a Participant wishes to change the
rate of payroll withholding, he or she may do so by filing a new enrollment form
with the Company at the prescribed location at any time.  The new withholding
rate shall be effective as soon as reasonably practicable after the Company has
received such form.  The new withholding rate shall be a whole percentage of the
Eligible Employee's Compensation, but not less than 1% nor more than 15%.

          (d) Discontinuing Payroll Deductions.  If a Participant wishes to
discontinue employee contributions entirely, he or she may do so by filing a new
enrollment form with the Company at the prescribed location at any time.
Payroll withholding shall cease as soon as reasonably practicable after the
Company has received such form.  (In addition, employee contributions may be
discontinued automatically pursuant to Section 8(b).)  A Participant who has
discontinued employee contributions may resume such contributions by filing a
new enrollment form with the Company at the prescribed location.  Payroll
withholding shall resume as soon as reasonably practicable after the Company has
received such form.

          (e) Limit on Number of Elections.  No Participant shall make more than
two elections under Subsection (c) or (d) above during any Accumulation Period
or such lesser or greater number of elections as may be permitted by the Board.

SECTION 5.  WITHDRAWAL FROM THE PLAN.

          (a) Withdrawal.  A Participant may elect to withdraw from the Plan by
filing the prescribed form with the Company at the prescribed location at any
time before the last day of an Accumulation Period.  As soon as reasonably
practicable thereafter, payroll deductions shall cease and the entire amount
credited to the Participant's Plan Account shall be refunded to him or her in
cash, without interest.  No partial withdrawals shall be permitted.

          (b) Re-Enrollment After Withdrawal.  A former Participant who has
withdrawn from the Plan shall not be a Participant until he or she re-enrolls in
the Plan under Section 3(c).  Re-enrollment may be effective only at the
commencement of an Offering Period.

SECTION 6.  CHANGE IN EMPLOYMENT STATUS.

          (a) Termination of Employment.  Termination of employment as an
Eligible Employee for any reason, including death, shall be treated as an
automatic withdrawal from the Plan under Section 5(a).  (A transfer from one
Participating Company to another shall not be treated as a termination of
employment.)

          (b) Leave of Absence.  For purposes of the Plan, employment shall not
be deemed to terminate when the Participant goes on a military leave, a sick
leave or another bona fide leave of absence, if the leave was approved by the
Company in writing.  Employment, however, shall be deemed to terminate 90 days
after the Participant goes on a leave, unless a contract or statute guarantees
his or her right to return to work.  Employment shall be deemed to terminate in
any event when the approved leave ends, unless the Participant immediately
returns to work.

                                       3
<PAGE>

          (c)  Death.  In the event of the Participant's death, the amount
credited to his or her Plan Account shall be paid to a beneficiary designated by
him or her for this purpose on the prescribed form or, if none, to the
Participant's estate.  Such form shall be valid only if it was filed with the
Company at the prescribed location before the Participant's death.

SECTION 7.  PLAN ACCOUNTS AND PURCHASE OF SHARES.

          (a)  Plan Accounts.  The Company shall maintain a Plan Account on its
books in the name of each Participant.  Whenever an amount is deducted from the
Participant's Compensation under the Plan, such amount shall be credited to the
Participant's Plan Account.  Amounts credited to Plan Accounts shall not be
trust funds and may be commingled with the Company's general assets and applied
to general corporate purposes.  No interest shall be credited to Plan Accounts.

          (b)  Purchase Price.  The Purchase Price for each share of Stock
purchased at the close of an Accumulation Period shall be the lower of:

          (i)  85% of the Fair Market Value of such share on the last trading
     day in such Accumulation Period; or

          (ii) 85% of the Fair Market Value of such share on the last trading
     day before the commencement of the applicable Offering Period (as
     determined under Section 3(e)) or, in the case of the first Offering Period
     under the Plan, 85% of the price at which one share of Stock is offered to
     the public in the IPO.

          (c)  Number of Shares Purchased.  As of the last day of each
Accumulation Period, each Participant shall be deemed to have elected to
purchase the number of shares of Stock calculated in accordance with this
Subsection (c), unless the Participant has previously elected to withdraw from
the Plan in accordance with Section 5(a).  The amount then in the Participant's
Plan Account shall be divided by the Purchase Price, and the number of shares
that results shall be purchased from the Company with the funds in the
Participant's Plan Account.  The foregoing notwithstanding, no Participant shall
purchase more than 2,500 shares of Stock with respect to any Accumulation Period
nor more than the amounts of Stock set forth in Sections 8(b) and 13(a).  The
Committee may determine with respect to all Participants that any fractional
share, as calculated under this Subsection (c), shall be (i) rounded down to the
next lower whole share or (ii) credited as a fractional share.

          (d)  Available Shares Insufficient.  In the event that the aggregate
number of shares that all Participants elect to purchase during an Accumulation
Period exceeds the maximum number of shares remaining available for issuance
under Section 13(a), then the number of shares to which each Participant is
entitled shall be determined by multiplying the number of shares available for
issuance by a fraction.  The numerator of such fraction is the number of shares
that such Participant has elected to purchase, and the denominator of such
fraction is the number of shares that all Participants have elected to purchase.

          (e)  Issuance of Stock.  Certificates representing the shares of Stock
purchased by a Participant under the Plan shall be issued to him or her as soon
as reasonably

                                       4
<PAGE>

practicable after the close of the applicable Accumulation Period, except that
the Committee may determine that such shares shall be held for each
Participant's benefit by a broker designated by the Committee (unless the
Participant has elected that certificates be issued to him or her). Shares may
be registered in the name of the Participant or jointly in the name of the
Participant and his or her spouse as joint tenants with right of survivorship or
as community property.

          (f)   Tax Withholding.  To the extent required by applicable federal,
state, local or foreign law, a Participant shall make arrangements satisfactory
to the Company for the satisfaction of any withholding tax obligations that
arise in connection with the Plan.  The Company shall not be required to issue
any shares of Stock under the Plan until such obligations are satisfied.

          (g)   Unused Cash Balances.  An amount remaining in the Participant's
Plan Account that represents the Purchase Price for any fractional share shall
be carried over in the Participant's Plan Account to the next Accumulation
Period.  Any amount remaining in the Participant's Plan Account that represents
the Purchase Price for whole shares that could not be purchased by reason of
Subsection (c) above, Section 8(b) or Section 13(a) shall be refunded to the
Participant in cash, without interest.

          (h)   Stockholder Approval.  Any other provision of the Plan
notwithstanding, no shares of Stock shall be purchased under the Plan unless and
until the Company's stockholders have approved the adoption of the Plan.

SECTION 8.  LIMITATIONS ON STOCK OWNERSHIP.

          (a)   Five Percent Limit.  Any other provision of the Plan
notwithstanding, no Participant shall be granted a right to purchase Stock under
the Plan if such Participant, immediately after his or her election to purchase
such Stock, would own stock possessing more than 5% of the total combined voting
power or value of all classes of stock of the Company or any parent or
Subsidiary of the Company.  For purposes of this Subsection (a), the following
rules shall apply:

          (i)   Ownership of stock shall be determined after applying the
     attribution rules of section 424(d) of the Code;

          (ii)  Each Participant shall be deemed to own any stock that he or she
     has a right or option to purchase under this or any other plan; and

          (iii) Each Participant shall be deemed to have the right to purchase
     2,500 shares of Stock under this Plan with respect to each Accumulation
     Period.

          (b)   Dollar Limit. Any other provision of the Plan notwithstanding,
no Participant shall purchase Stock with a Fair Market Value in excess of the
following limit:

          (i)   In the case of Stock purchased during an Offering Period that
     commenced in the current calendar year, the limit shall be equal to (A)
     $25,000 minus (B) the Fair Market Value of the Stock that the Participant
     previously

                                       5
<PAGE>

     purchased in the current calendar year (under this Plan and all other
     employee stock purchase plans of the Company or any parent or Subsidiary of
     the Company).

          (ii)  In the case of Stock purchased during an Offering Period that
     commenced in the immediately preceding calendar year, the limit shall be
     equal to (A) $50,000 minus (B) the Fair Market Value of the Stock that the
     Participant previously purchased (under this Plan and all other employee
     stock purchase plans of the Company or any parent or Subsidiary of the
     Company) in the current calendar year and in the immediately preceding
     calendar year.

          (iii) In the case of Stock purchased during an Offering Period that
     commenced in the second preceding calendar year, the limit shall be equal
     to (A) $75,000 minus (B) the Fair Market Value of the Stock that the
     Participant previously purchased (under this Plan and all other employee
     stock purchase plans of the Company or any parent or Subsidiary of the
     Company) in the current calendar year and in the two preceding calendar
     years.

For purposes of this Subsection (b), the Fair Market Value of Stock shall be
determined in each case as of the beginning of the Offering Period in which such
Stock is purchased.  Employee stock purchase plans not described in section 423
of the Code shall be disregarded.  If a Participant is precluded by this
Subsection (b) from purchasing additional Stock under the Plan, then his or her
employee contributions shall automatically be discontinued and shall resume at
the beginning of the earliest Accumulation Period ending in the next calendar
year (if he or she then is an Eligible Employee).

SECTION 9.  RIGHTS NOT TRANSFERABLE.

          The rights of any Participant under the Plan, or any Participant's
interest in any Stock or moneys to which he or she may be entitled under the
Plan, shall not be transferable by voluntary or involuntary assignment or by
operation of law, or in any other manner other than by beneficiary designation
or the laws of descent and distribution.  If a Participant in any manner
attempts to transfer, assign or otherwise encumber his or her rights or interest
under the Plan, other than by beneficiary designation or the laws of descent and
distribution, then such act shall be treated as an election by the Participant
to withdraw from the Plan under Section 5(a).

SECTION 10. NO RIGHTS AS AN EMPLOYEE.

          Nothing in the Plan or in any right granted under the Plan shall
confer upon the Participant any right to continue in the employ of a
Participating Company for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Participating Companies or of
the Participant, which rights are hereby expressly reserved by each, to
terminate his or her employment at any time and for any reason, with or without
cause.

                                       6
<PAGE>

SECTION 11. NO RIGHTS AS A STOCKHOLDER.

          A Participant shall have no rights as a stockholder with respect to
any shares of Stock that he or she may have a right to purchase under the Plan
until such shares have been purchased on the last day of the applicable
Accumulation Period.

SECTION 12. SECURITIES LAW REQUIREMENTS.

          Shares of Stock shall not be issued under the Plan unless the issuance
and delivery of such shares comply with (or are exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange or other
securities market on which the Company's securities may then be traded.

SECTION 13. STOCK OFFERED UNDER THE PLAN.

          (a) Authorized Shares.  The number of shares of Stock available for
purchase under the Plan shall be 1,000,000 (subject to adjustment pursuant to
this Section 13).  On January 1 of each year, commencing with January 1, 2001,
the aggregate number of shares of Stock available for purchase during the life
of the Plan shall automatically be increased by a number equal to the lesser of
2% of the total number of shares of Common Stock then outstanding or 600,000
shares.

          (b) Anti-Dilution Adjustments.  The aggregate number of shares of
Stock offered under the Plan, the 2,500-share limitation described in Section
7(c), the 600,000-share limitation described in Section 13(a) and the price of
shares that any Participant has elected to purchase shall be adjusted
proportionately by the Committee for any increase or decrease in the number of
outstanding shares of Stock resulting from a subdivision or consolidation of
shares or the payment of a stock dividend, any other increase or decrease in
such shares effected without receipt or payment of consideration by the Company,
the distribution of the shares of a Subsidiary to the Company's stockholders or
a similar event.

          (c) Reorganizations.  Any other provision of the Plan notwithstanding,
immediately prior to the effective time of a Corporate Reorganization, the
Offering Period and Accumulation Period then in progress shall terminate and
shares shall be purchased pursuant to Section 7, unless the Plan is continued or
assumed by the surviving corporation or its parent corporation.  The Plan shall
in no event be construed to restrict in any way the Company's right to undertake
a dissolution, liquidation, merger, consolidation or other reorganization.

SECTION 14. AMENDMENT OR DISCONTINUANCE.

          The Board shall have the right to amend, suspend or terminate the Plan
at any time and without notice.  The Company's Chief Executive Officer may also
amend the Plan to the extent allowable under applicable law to effect non-
material amendments. Except as provided in Section 13, any increase in the
aggregate number of shares of Stock to be issued under the Plan shall be subject
to approval by a vote of the stockholders of the Company.  In

                                       7
<PAGE>

addition, any other amendment of the Plan shall be subject to approval by a vote
of the stockholders of the Company to the extent required by an applicable law
or regulation. The Plan shall terminate automatically 20 years after its
adoption by the Board, unless (a) the Plan is extended by the Board and (b) the
extension is approved within 12 months by a vote of the stockholders of the
Company.
