        3.      ELIGIBILITY.

                (a)     Any person who is an Employee as of the Offering Date of
a given Offering Period shall be eligible to participate in such Offering Period
under the Plan, subject to the requirements of Section 5(a) and the limitations
imposed by Section 423(b) of the Code; provided however that eligible Employees
may not participate in more than one Offering Period at a time.

                (b)     Any provisions of the Plan to the contrary
notwithstanding, no Employee shall be granted an option under the Plan (i) if,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase stock possessing five percent (5%) or more of the total combined voting
power or value of all classes of stock of the Company or of any subsidiary of
the Company, or (ii) if such option would permit his or her rights to purchase
stock under all employee stock purchase plans (described in Section 423 of the
Code) of the Company and its Subsidiaries to accrue at a rate which exceeds
Twenty-Five Thousand Dollars ($25,000) of the Fair Market Value (as defined in
Section 7(b) below) of such stock (determined at the time such option is
granted) for each calendar year in which such option is outstanding at any time.

        4.      OFFERING PERIODS AND PURCHASE PERIODS.

                (a)     OFFERING PERIODS. The Plan shall be implemented by a
series of Offering Periods of twenty-four (24) months' duration, with new
Offering Periods commencing on or about November 1 and May 1 of each year (or at
such other time or times as may be determined by the Board of Directors). The
first Offering Period shall commence on November 1, 1999 and continue until
October 31, 2001. The Plan shall continue until terminated in accordance with
Section 19 hereof. The Board of Directors of the Company shall have the power to
change the duration and/or the frequency of Offering Periods with respect to
future offerings without stockholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected.

                (b)     PURCHASE PERIODS. Each Offering Period shall consist of
four (4) consecutive purchase periods of six (6) months' duration. The last day
of each Purchase Period shall be the "Purchase Date" for such Purchase Period. A
Purchase Period commencing on November 1 shall end on the next April 30. A
Purchase Period commencing on May 1 shall end on the next October 31. The first
Purchase Period shall commence on November 1, 1999 and shall end on April 30,
2000. The Board of Directors of the Company shall have the power to change the
duration and/or frequency of Purchase Periods with respect to future purchases
without stockholder approval if such change is announced at least five (5) days
prior to the scheduled beginning of the first Purchase Period to be affected.

        5.      PARTICIPATION.

                (a)     An eligible Employee may become a participant in the
Plan by completing a subscription agreement on the form provided by the Company
and filing it with the Company's

<PAGE>   4
Equity Compensation Department prior to the applicable Offering Date, unless a
later time for filing the subscription agreement is set by the Board for all
eligible Employees with respect to a given Offering Period. The subscription
agreement shall set forth the percentage of the participant's Compensation
(subject to Section 6(a) below) to be paid as Contributions pursuant to the
Plan.

                (b)     Payroll deductions shall commence on the first payroll
following the Offering Date and shall end on the last payroll paid on or prior
to the last Purchase Period of the Offering Period to which the subscription
agreement is applicable, unless sooner terminated by the participant as provided
in Section 10.

        6.      METHOD OF PAYMENT OF CONTRIBUTIONS.

                (a)     A participant shall elect to have payroll deductions
made on each payday during the Offering Period in an amount not less than one
percent (1%) and not more than twenty percent (20%) (or such greater percentage
as the Board may establish from time to time before an Offering Date). All
payroll deductions made by a participant shall be credited to his or her account
under the Plan. A participant may not make any additional payments into such
account.

                (b)     A participant may discontinue his or her participation
in the Plan as provided in Section 10, or, on one occasion only during a
Purchase Period may increase and on one occasion only during a Purchase Period
may decrease the rate of his or her Contributions with respect to the Offering
Period by completing and filing with the Company a new subscription agreement
authorizing a change in the payroll deduction rate. A change increasing the
payroll deduction rate shall be effective as of the beginning of the next
Purchase Period following the date of filing of the new subscription agreement.
A change decreasing the payroll deduction rate shall be effective as soon as
possible following the date of filing of the new subscription agreement.

                (c)     Notwithstanding the foregoing, to the extent necessary
to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during a Purchase Period. Payroll deductions shall re-commence at Purchase
Offering Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10.

        7.      GRANT OF OPTION.

                (a)     On the Offering Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Purchase Date a number of Shares of the Company's
Common Stock determined by dividing such Employee's Contributions accumulated
prior to such Purchase Date and retained in the participant's account as of the
Purchase Date by the applicable Purchase Price; provided however that the
maximum number of Shares an Employee may purchase during each Purchase Period
shall be 2,000 Shares (subject to any adjustment pursuant to Section 19 below),
and provided further that such purchase shall be subject to the limitations set
forth in Sections 3(b) and 13.


<PAGE>   5
                (b)     The fair market value of the Company's Common Stock on a
given date (the "Fair Market Value") shall be determined by the Board in its
discretion based on the closing sales price of the Common Stock for such date
(or, in the event that the Common Stock is not traded on such date, on the
immediately preceding trading date), as reported by the National Association of
Securities Dealers Automated Quotation (Nasdaq) National Market or, if such
price is not reported, the mean of the bid and asked prices per share of the
Common Stock as reported by Nasdaq or, in the event the Common Stock is listed
on a stock exchange, the Fair Market Value per share shall be the closing sales
price on such exchange on such date (or, in the event that the Common Stock is
not traded on such date, on the immediately preceding trading date), as reported
in The Wall Street Journal.

        8.      EXERCISE OF OPTION. Unless a participant withdraws from the Plan
as provided in Section 10, his or her option for the purchase of Shares will be
exercised automatically on each Purchase Date of an Offering Period, and the
maximum number of full Shares subject to the option will be purchased at the
applicable Purchase Price with the accumulated Contributions in his or her
account. No fractional Shares shall be issued. The Shares purchased upon
exercise of an option hereunder shall be deemed to be transferred to the
participant on the Purchase Date. During his or her lifetime, a participant's
option to purchase Shares hereunder is exercisable only by him or her.

        9.      DELIVERY. As promptly as practicable after each Purchase Date of
each Offering Period, the Company shall deposit the Shares purchased upon
exercise of a participant's option into the participant's account with the
broker selected by the Company for administration of the Plan stock purchases.
Any payroll deductions accumulated in a participant's account which are not
sufficient to purchase a full Share shall be retained in the participant's
account for the subsequent Purchase Period or Offering Period, subject to
earlier withdrawal by the participant as provided in Section 10 below. Any other
amounts left over in a participant's account after a Purchase Date shall be
returned to the participant.

        10.     VOLUNTARY WITHDRAWAL; TERMINATION OF EMPLOYMENT.

                (a)     A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
each Purchase Date by giving written notice to the Company. All of the
participant's Contributions credited to his or her account will be paid to him
or her promptly after receipt of his or her notice of withdrawal and his or her
option for the current period will be automatically terminated, and no further
Contributions for the purchase of Shares will be made during the Offering
Period.

                (b)     Upon termination of the participant's Continuous Status
as an Employee prior to the Purchase Date of an Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto, and his or her option will be automatically
terminated.

                (c)     In the event an Employee fails to remain in Continuous
Status as an Employee of the Company for at least twenty (20) hours per week
during the Offering Period in


<PAGE>   6
which the employee is a participant, he or she will be deemed to have elected to
withdraw from the Plan and the Contributions credited to his or her account will
be returned to him or her and his or her option terminated.

                (d)     A participant's withdrawal from an offering will not
have any effect upon his or her eligibility to participate in a succeeding
offering or in any similar plan which may hereafter be adopted by the Company.

        11.     AUTOMATIC WITHDRAWAL. If the Fair Market Value of the Shares on
any Purchase Date of an Offering Period is less than the Fair Market Value of
the Shares on the Offering Date for such Offering Period, then every participant
shall automatically (i) be withdrawn from such Offering Period at the close of
such Purchase Date and after the acquisition of Shares for such Purchase Period,
and (ii) be enrolled in the Offering Period commencing on the first business day
subsequent to such Purchase Period.

        12.     INTEREST. No interest shall accrue on the Contributions of a
participant in the Plan.

        13.     STOCK.

                (a)     Subject to adjustment as provided in Section 19, the
maximum number of Shares which shall be made available for sale under the Plan
shall be 1,000,000 Shares, plus an annual increase on the first day of each of
the Company's fiscal years beginning in 2000, 2001, 2002, 2003 and 2004 equal to
the lesser of (i) 500,000 Shares, (ii) five percent (5%) of the Shares
outstanding on the last day of the immediately preceding fiscal year, or (iii)
such lesser number of Shares as is determined by the Board. If the Board
determines that, on a given Purchase Date, the number of shares with respect to
which options are to be exercised may exceed (i) the number of shares of Common
Stock that were available for sale under the Plan on the Offering Date of the
applicable Offering Period, or (ii) the number of shares available for sale
under the Plan on such Purchase Date, the Board may in its sole discretion
provide (x) that the Company shall make a pro rata allocation of the Shares of
Common Stock available for purchase on such Offering Date or Purchase Date, as
applicable, in as uniform a manner as shall be practicable and as it shall
determine in its sole discretion to be equitable among all participants
exercising options to purchase Common Stock on such Purchase Date, and continue
all Offering Periods then in effect, or (y) that the Company shall make a pro
rata allocation of the shares available for purchase on such Offering Date or
Purchase Date, as applicable, in as uniform a manner as shall be practicable and
as it shall determine in its sole discretion to be equitable among all
participants exercising options to purchase Common Stock on such Purchase Date,
and terminate any or all Offering Periods then in effect pursuant to Section 20
below. The Company may make pro rata allocation of the Shares available on the
Offering Date of any applicable Offering Period pursuant to the preceding
sentence, notwithstanding any authorization of additional Shares for issuance
under the Plan by the Company's stockholders subsequent to such Offering Date.

                (b)     The participant shall have no interest or voting right
in Shares covered by his or her option until such option has been exercised.


<PAGE>   7
                (c)     Shares to be delivered to a participant under the Plan
will be registered in the name of the participant only.

        14.     ADMINISTRATION. The Board, or a committee named by the Board,
shall supervise and administer the Plan and shall have full power to adopt,
amend and rescind any rules deemed desirable and appropriate for the
administration of the Plan and not inconsistent with the Plan, to construe and
interpret the Plan, and to make all other determinations necessary or advisable
for the administration of the Plan.

        15.     TRANSFERABILITY. Neither Contributions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive Shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 15) by the participant. Any such attempt
at assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds in
accordance with Section 10.

        16.     USE OF FUNDS. All Contributions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such Contributions.

        17.     REPORTS. Individual accounts will be maintained for each
participant in the Plan. Statements of account will be given to participating
Employees at least annually, which statements will set forth the amounts of
Contributions, the per Share Purchase Price, the number of Shares purchased and
the remaining cash balance, if any.

        18.     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE
TRANSACTIONS.

                (a)     ADJUSTMENT. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each option under
the Plan which has not yet been exercised and the number of Shares which have
been authorized for issuance under the Plan but have not yet been placed under
option (collectively, the "Reserves"), as well as the maximum number of shares
of Common Stock which may be purchased by a participant in a Purchase Period,
the number of shares of Common Stock set forth in Section 13(a)(i) above, and
the price per Share of Common Stock covered by each option under the Plan which
has not yet been exercised, shall be proportionately adjusted for any increase
or decrease in the number of issued Shares resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common Stock
(including any such change in the number of Shares of Common Stock effected in
connection with a change in domicile of the Company), or any other increase or
decrease in the number of Shares effected without receipt of consideration by
the Company; provided however that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issue 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 an option.


<PAGE>   8
                (b)     CORPORATE TRANSACTIONS. In the event of a dissolution or
liquidation of the Company, any Purchase Period and Offering Period then in
progress will terminate immediately prior to the consummation of such action,
unless otherwise provided by the Board. In the event of a Corporate Transaction,
each option outstanding under the Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or Subsidiary of
such successor corporation. In the event that the successor corporation refuses
to assume or substitute for outstanding options, each Purchase Period and
Offering Period then in progress shall be shortened and a new Purchase Date
shall be set (the "New Purchase Date"), as of which date any Purchase Period and
Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the transaction and the Board shall
notify each participant in writing, at least ten (10) days prior to the New
Purchase Date, that the Purchase Date for his or her option has been changed to
the New Purchase Date and that his or her option will be exercised automatically
on the New Purchase Date, unless prior to such date he or she has withdrawn from
the Offering Period as provided in Section 10. For purposes of this Section 19,
an option granted under the Plan shall be deemed to be assumed, without
limitation, if, at the time of issuance of the stock or other consideration upon
a Corporate Transaction, each holder of an option under the Plan would be
entitled to receive upon exercise of the option the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the
transaction if the holder had been, immediately prior to the transaction, the
holder of the number of Shares of Common Stock covered by the option at such
time (after giving effect to any adjustments in the number of Shares covered by
the option as provided for in this Section 19); provided however that if the
consideration received in the transaction is not solely common stock of the
successor corporation or its parent (as defined in Section 424(e) of the Code),
the Board may, with the consent of the successor corporation, provide for the
consideration to be received upon exercise of the option to be solely common
stock of the successor corporation or its parent equal in Fair Market Value to
the per Share consideration received by holders of Common Stock in the
transaction.

        The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per Share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of Shares of its outstanding Common
Stock, and in the event of the Company's being consolidated with or merged into
any other corporation.

        19.     AMENDMENT OR TERMINATION.

                (a)     The Board may at any time and for any reason terminate
or amend the Plan. Except as provided in Section 19, no such termination of the
Plan may affect options previously granted, provided that the Plan or an
Offering Period may be terminated by the Board on a Purchase Date or by the
Board's setting a new Purchase Date with respect to an Offering Period and
Purchase Period then in progress if the Board determines that termination of the
Plan and/or the Offering Period is in the best interests of the Company and the
stockholders or if continuation of the Plan and/or the Offering Period would
cause the Company to incur adverse accounting charges as a result of a change
after the effective date of the Plan in the generally


<PAGE>   9
accepted accounting rules applicable to the Plan. Except as provided in Section
19 and in this Section 20, no amendment to the Plan shall make any change in any
option previously granted which adversely affects the rights of any participant.
In addition, to the extent necessary to comply with Rule 16b-3 under the
Exchange Act, or under Section 423 of the Code (or any successor rule or
provision or any applicable law or regulation), the Company shall obtain
stockholder approval in such a manner and to such a degree as so required.

                (b)     Without stockholder consent and without regard to
whether any participant rights may be considered to have been adversely
affected, the Board (or its committee) shall be entitled to change the Offering
Periods and Purchase Periods, limit the frequency and/or number of changes in
the amount withheld during an Offering Period, establish the exchange ratio
applicable to amounts withheld in a currency other than U.S. dollars, permit
payroll withholding in excess of the amount designated by a participant in order
to adjust for delays or mistakes in the Company's processing of properly
completed withholding elections, establish reasonable waiting and adjustment
periods and/or accounting and crediting procedures to ensure that amounts
applied toward the purchase of Common Stock for each participant properly
correspond with amounts withheld from the participant's Compensation, and
establish such other limitations or procedures as the Board (or its committee)
determines in its sole discretion advisable which are consistent with the Plan.

        20.     NOTICES. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

        21.     CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued
with respect to an option unless the exercise of such option and the issuance
and delivery of such Shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, applicable state securities laws and the requirements of
any stock exchange upon which the Shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

        As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

        22.     TERM OF PLAN; EFFECTIVE DATE. The Plan shall become effective
upon its approval by the Company's stockholders. It shall continue in effect for
a term of twenty (20) years unless sooner terminated under Section 20.

        23.     ADDITIONAL RESTRICTIONS OF RULE 16b-3. The terms and conditions
of options granted hereunder to, and the purchase of Shares by, persons subject
to Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3. This Plan shall be


<PAGE>   10
deemed to contain, and such options shall contain, and the Shares issued upon
exercise thereof shall be subject to, such additional conditions and
restrictions as may be required by Rule 16b-3 to qualify for the maximum
exemption from Section 16 of the Exchange Act with respect to Plan transactions.
