        (a) The Board shall administer the Plan unless and until the Board
delegates administration to a Committee, as provided in Section 3(c). Whether or
not the Board has delegated administration, the Board shall have the final power
to determine all questions of policy and expediency that may arise in the
administration of the Plan.

        (b) The Board (or the Committee) shall have the power, subject to, and
within the express limitations of, the provisions of the Plan:

            (i) To determine when and how Purchase Rights to purchase shares of
Common Stock shall be granted and the provisions of each Offering of such
Purchase Rights (which need not be identical).

            (ii) To designate from time to time which Related Corporations of
the Company shall be eligible to participate in the Plan.

            (iii) To construe and interpret the Plan and Purchase Rights granted
under the Plan, and to establish, amend and revoke rules and regulations for the
administration of the Plan. The Board, in the exercise of this power, may
correct any defect, omission or inconsistency in


                                      -3-


the Plan, in a manner and to the extent it shall deem necessary or expedient to
make the Plan fully effective.

            (iv) To amend the Plan as provided in Section 15.

            (v) Generally, to exercise such powers and to perform such acts as
it deems necessary or expedient to promote the best interests of the Company and
its Related Corporations and to carry out the intent that the Plan be treated as
an Employee Stock Purchase Plan.

        (c) The Board may delegate administration of the Plan to a Committee of
the Board composed of two (2) or more members of the Board. If administration is
delegated to a Committee, the Committee shall have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board,
subject, however, to such resolutions, not inconsistent with the provisions of
the Plan, as may be adopted from time to time by the Board. The Board may
abolish the Committee at any time and revest in the Board the administration of
the Plan. If administration is delegated to a Committee, references to the Board
in this Plan and in the Offering document shall thereafter be deemed to be to
the Board or the Committee, as the case may be.

4.      SHARES OF COMMON STOCK SUBJECT TO THE PLAN.

        Subject to the provisions of Section 14 relating to adjustments upon
changes in securities, the shares of Common Stock that may be sold pursuant to
Purchase Rights granted under the Plan shall not exceed in the aggregate two
hundred thousand (200,000) shares of Common Stock. If any Purchase Right granted
under the Plan shall for any reason terminate without having been exercised, the
shares of Common Stock not purchased under such Purchase Right shall again
become available for issuance under the Plan.

5.      GRANT OF PURCHASE RIGHTS; OFFERING.

        (a) The Board may from time to time grant or provide for the grant of
Purchase Rights to purchase shares of Common Stock under the Plan to Eligible
Employees in an Offering (consisting of one or more Purchase Periods) on an
Offering Date or Offering Dates selected by the Board. Each Offering shall be in
such form and shall contain such terms and conditions as the Board shall deem
appropriate, which shall comply with the requirement of Section 423(b)(5) of the
Code that all Employees granted Purchase Rights to purchase shares of Common
Stock under the Plan shall have the same rights and privileges. The terms and
conditions of an Offering shall be incorporated by reference into the Plan and
treated as part of the Plan. The provisions of separate Offerings need not be
identical, but each Offering shall include (through incorporation of the
provisions of this Plan by reference in the document comprising the Offering or
otherwise) the period during which the Offering shall be effective, which period
shall not exceed twenty-seven (27) months beginning with the Offering Date, and
the substance of the provisions contained in Sections 6 through 9, inclusive.

        (b) If a Participant has more than one Purchase Right outstanding under
the Plan, unless he or she otherwise indicates in agreements or notices
delivered hereunder: (i) each


                                      -4-


agreement or notice delivered by that Participant shall be deemed to apply to
all of his or her Purchase Rights under the Plan, and (ii) a Purchase Right with
a lower exercise price (or an earlier-granted Purchase Right, if different
Purchase Rights have identical exercise prices) shall be exercised to the
fullest possible extent before a Purchase Right with a higher exercise price (or
a later-granted Purchase Right, if different Purchase Rights have identical
exercise prices) shall be exercised.

6.      ELIGIBILITY.

        (a) Purchase Rights may be granted only to Employees of the Company or,
as the Board may designate as provided in Section 3(b), to Employees of a
Related Corporation. Except as provided in Section 6(b), an Employee shall not
be eligible to be granted Purchase Rights under the Plan unless, on the Offering
Date, such Employee has been in the employ of the Company or the Related
Corporation, as the case may be, for such continuous period preceding such
Offering Date as the Board may require, but in no event shall the required
period of continuous employment be greater than two (2) years. In addition, the
Board may provide that no Employee shall be eligible to be granted Purchase
Rights under the Plan unless, on the Offering Date, such Employee's customary
employment with the Company or the Related Corporation is more than twenty (20)
hours per week and more than five (5) months per calendar year.

        (b) The Board may provide that each person who, during the course of an
Offering, first becomes an Eligible Employee shall, on a date or dates specified
in the Offering which coincides with the day on which such person becomes an
Eligible Employee or which occurs thereafter, receive a Purchase Right under
that Offering, which Purchase Right shall thereafter be deemed to be a part of
that Offering. Such Purchase Right shall have the same characteristics as any
Purchase Rights originally granted under that Offering, as described herein,
except that:

            (i) the date on which such Purchase Right is granted shall be the
"Offering Date" of such Purchase Right for all purposes, including determination
of the exercise price of such Purchase Right;

            (ii) the period of the Offering with respect to such Purchase Right
shall begin on its Offering Date and end coincident with the end of such
Offering; and

            (iii) the Board may provide that if such person first becomes an
Eligible Employee within a specified period of time before the end of the
Offering, he or she shall not receive any Purchase Right under that Offering.

        (c) No Employee shall be eligible for the grant of any Purchase Rights
under the Plan if, immediately after any such Purchase Rights are granted, such
Employee owns 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 Related
Corporation. For purposes of this Section 6(c), the rules of Section 424(d) of
the Code shall apply in determining the stock ownership of any Employee, and
stock which such Employee may purchase under all outstanding Purchase Rights and
options shall be treated as stock owned by such Employee.


                                      -5-


        (d) As specified by Section 423(b)(8) of the Code, an Eligible Employee
may be granted Purchase Rights under the Plan only if such Purchase Rights,
together with any other rights granted under all Employee Stock Purchase Plans
of the Company and any Related Corporations, do not permit such Eligible
Employee's rights to purchase stock of the Company or any Related Corporation to
accrue at a rate which exceeds twenty five thousand dollars ($25,000) of Fair
Market Value of such stock (determined at the time such rights are granted, and
which, with respect to the Plan, shall be determined as of their respective
Offering Dates) for each calendar year in which such rights are outstanding at
any time.

        (e) Officers of the Company and any designated Related Corporation, if
they are otherwise Eligible Employees, shall be eligible to participate in
Offerings under the Plan. Notwithstanding the foregoing, the Board may provide
in an Offering that Employees who are highly compensated Employees within the
meaning of Section 423(b)(4)(D) of the Code shall not be eligible to
participate.

7.      PURCHASE RIGHTS; PURCHASE PRICE.

        (a) On each Offering Date, each Eligible Employee, pursuant to an
Offering made under the Plan, shall be granted a Purchase Right to purchase up
to that number of shares of Common Stock purchasable either with a percentage or
with a maximum dollar amount, as designated by the Board, but in either case not
exceeding fifteen percent (15%), of such Employee's Earnings (as defined by the
Board in each Offering) during the period that begins on the Offering Date (or
such later date as the Board determines for a particular Offering) and ends on
the date stated in the Offering, which date shall be no later than the end of
the Offering.

        (b) The Board shall establish one (1) or more Purchase Dates during an
Offering as of which Purchase Rights granted under the Plan and pursuant to that
Offering shall be exercised and purchases of shares of Common Stock shall be
carried out in accordance with such Offering.

        (c) In connection with each Offering made under the Plan, the Board may
specify a maximum number of shares of Common Stock that may be purchased by any
Participant on any Purchase Date during such Offering. In connection with each
Offering made under the Plan, the Board may specify a maximum aggregate number
of shares of Common Stock that may be purchased by all Participants pursuant to
such Offering. In addition, in connection with each Offering that contains more
than one Purchase Date, the Board may specify a maximum aggregate number of
shares of Common Stock that may be purchased by all Participants on any given
Purchase Date under the Offering. If the aggregate purchase of shares of Common
Stock issuable upon exercise of Purchase Rights granted under the Offering would
exceed any such maximum aggregate number, then, in the absence of any Board
action otherwise, a pro rata allocation of the shares of Common Stock available
shall be made in as nearly a uniform manner as shall be practicable and
equitable.

        (d) The purchase price of each share of Common Stock acquired pursuant
to a Purchase Right shall be not less than the lesser of:


                                      -6-

                (i) an amount equal to eighty-five percent (85%) of the Fair
Market Value of a share of Common Stock on the Offering Date; or

                (ii) an amount equal to eighty-five percent (85%) of the Fair
Market Value of a share of Common Stock on the applicable Purchase Date.

8.      PARTICIPATION; WITHDRAWAL; TERMINATION.

        (a) By completing and delivering to the Company, within the time
specified in the Offering, an enrollment form (in such form as the Company may
provide), an Eligible Employee shall become a Participant in the Plan. Each such
enrollment form shall authorize an amount of Contributions expressed as a
percentage of the submitting Participant's Earnings (as defined in each
Offering) during the Offering (not to exceed the maximum percentage specified by
the Board). Each Participant's Contributions shall be credited to a bookkeeping
account for such Participant under the Plan and shall be deposited with the
general funds of the Company except where applicable law requires that
Contributions be deposited with a third party. To the extent provided in the
Offering, a Participant may begin such Contributions after the beginning of the
Offering. To the extent provided in the Offering, a Participant may thereafter
reduce (including to zero) or increase his or her Contributions.

        (b) During an Offering, a Participant may cease making Contributions and
withdraw from the Offering by delivering to the Company a notice of withdrawal
in such form as the Company may provide. Such withdrawal may be elected at any
time prior to the end of the Offering, except as provided otherwise in the
Offering. Upon such withdrawal from the Offering by a Participant, the Company
shall distribute to such Participant all of his or her accumulated Contributions
(reduced to the extent, if any, such deductions have been used to acquire shares
of Common Stock for the Participant) under the Offering, and such Participant's
Purchase Right in that Offering shall thereupon terminate. A Participant's
withdrawal from an Offering shall have no effect upon such Participant's
eligibility to participate in any other Offerings under the Plan, but such
Participant shall be required to deliver a new enrollment form in order to
participate in subsequent Offerings.

        (c) Purchase Rights granted pursuant to any Offering under the Plan
shall terminate immediately upon a Participant ceasing to be an Employee for any
reason or for no reason (subject to any post-employment participation period
required by law) or other lack of eligibility. The Company shall distribute to
such terminated or otherwise ineligible Employee all of his or her accumulated
Contributions (reduced to the extent, if any, such deductions have been used to
acquire shares of Common Stock for the terminated or otherwise ineligible
Employee) under the Offering.

        (d) Purchase Rights granted under the Plan shall not be transferable by
a Participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in Section 13 and, during a
Participant's lifetime, shall be exercisable only by such Participant.


                                      -7-


        (e) Unless otherwise specified in an Offering, the Company shall have no
obligation to pay interest on Contributions.

9.      EXERCISE.

        (a) On each Purchase Date during an Offering, each Participant's
accumulated Contributions shall be applied to the purchase of shares of Common
Stock up to the maximum number of shares of Common Stock permitted pursuant to
the terms of the Plan and the applicable Offering, at the purchase price
specified in the Offering. No fractional shares shall be issued upon the
exercise of Purchase Rights granted under the Plan unless specifically provided
for in the Offering.

        (b) If any amount of accumulated Contributions remains in a
Participant's account after the purchase of shares of Common Stock and such
remaining amount is less than the amount required to purchase one share of
Common Stock on the final Purchase Date of an Offering, then such remaining
amount shall be held in such Participant's account for the purchase of shares of
Common Stock under the next Offering under the Plan, unless such Participant
withdraws from such next Offering, as provided in Section 8(b), or is not
eligible to participate in such Offering, as provided in Section 6, in which
case such amount shall be distributed to such Participant after said final
Purchase Date. If the amount of Contributions remaining in a Participant's
account after the purchase of shares of Common Stock is at least equal to the
amount required to purchase one (1) whole share of Common Stock on the final
Purchase Date of the Offering, then such remaining amount shall be distributed
in full to such Participant at the end of the Offering.

        (c) No Purchase Rights granted under the Plan may be exercised to any
extent unless the shares of Common Stock to be issued upon such exercise under
the Plan are covered by an effective registration statement pursuant to the
Securities Act and the Plan is in material compliance with all applicable
federal, state, foreign and other securities and other laws applicable to the
Plan. If on a Purchase Date during any Offering hereunder the shares of Common
Stock are not so registered or the Plan is not in such compliance, no Purchase
Rights granted under the Plan or any Offering shall be exercised on such
Purchase Date, and the Purchase Date shall be delayed until the shares of Common
Stock are subject to such an effective registration statement and the Plan is in
such compliance, except that the Purchase Date shall not be delayed more than
twelve (12) months and the Purchase Date shall in no event be more than
twenty-seven (27) months from the Offering Date. If, on the Purchase Date under
any Offering hereunder, as delayed to the maximum extent permissible, the shares
of Common Stock are not registered and the Plan is not in such compliance, no
Purchase Rights granted under the Plan or any Offering shall be exercised and
all Contributions accumulated during the Offering (reduced to the extent, if
any, such deductions have been used to acquire shares of Common Stock) shall be
distributed to the Participants.


                                      -8-


10.     COVENANTS OF THE COMPANY.

        (a) During the terms of the Purchase Rights granted under the Plan, the
Company shall ensure that the amount of shares of Common Stock required to
satisfy such Purchase Rights are available.

        (b) The Company shall seek to obtain from each federal, state, foreign
or other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of Common Stock upon
exercise of the Purchase Rights granted under the Plan. If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or
agency the authority that counsel for the Company deems necessary for the lawful
issuance and sale of shares of Common Stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell shares of Common Stock
upon exercise of such Purchase Rights unless and until such authority is
obtained.

11.     USE OF PROCEEDS FROM SHARES OF COMMON STOCK.

        Proceeds from the sale of shares of Common Stock pursuant to Purchase
Rights granted under the Plan shall constitute general funds of the Company.

12.     RIGHTS AS A STOCKHOLDER.

        A Participant shall not be deemed to be the holder of, or to have any of
the rights of a holder with respect to, shares of Common Stock subject to
Purchase Rights granted under the Plan unless and until the Participant's shares
of Common Stock acquired upon exercise of Purchase Rights granted under the Plan
are recorded in the books of the Company (or its transfer agent).

13.     DESIGNATION OF BENEFICIARY.

        (a) A Participant may file a written designation of a beneficiary who is
to receive any shares of Common Stock and/or cash, if any, from the
Participant's account under the Plan in the event of such Participant's death
subsequent to the end of an Offering but prior to delivery to the Participant of
such shares of Common Stock or cash. In addition, a Participant may file a
written designation of a beneficiary who is to receive any cash from the
Participant's account under the Plan in the event of such Participant's death
during an Offering.

        (b) The Participant may change such designation of beneficiary at any
time by written notice. In the event of the death of a Participant and in the
absence of a beneficiary validly designated under the Plan who is living at the
time of such Participant's death, the Company shall deliver such shares of
Common Stock and/or cash to the executor or administrator of the estate of the
Participant, or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its sole discretion, may deliver such
shares of Common Stock and/or cash to the spouse or to any one or more
dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Company, then to such other person as the Company may
designate.


                                      -9-


14.     ADJUSTMENTS UPON CHANGES IN SECURITIES; CORPORATE TRANSACTIONS.

        (a) If any change is made in the shares of Common Stock, subject to the
Plan, or subject to any Purchase Right, without the receipt of consideration by
the Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan shall be appropriately adjusted in the
type(s), class(es) and maximum number of shares of Common Stock subject to the
Plan pursuant to Section 4(a), and the outstanding Purchase Rights granted under
the Plan shall be appropriately adjusted in the type(s), class(es), number of
shares and purchase limits of such outstanding Purchase Rights. The Board shall
make such adjustments, and its determination shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a "transaction not involving the receipt of consideration by
the Company.")

        (b) In the event of a Corporate Transaction, then: (i) any surviving or
acquiring corporation may continue or assume Purchase Rights outstanding under
the Plan or may substitute similar rights (including a right to acquire the same
consideration paid to stockholders in the Corporate Transaction) for those
outstanding under the Plan, or (ii) if any surviving or acquiring corporation
does not assume such Purchase Rights or does not substitute similar rights for
Purchase Rights outstanding under the Plan, then, the Participants' accumulated
Contributions shall be used to purchase shares of Common Stock immediately prior
to the Corporate Transaction under the ongoing Offering, and the Participants'
Purchase Rights under the ongoing Offering shall terminate immediately after
such purchase.

15.     AMENDMENT OF THE PLAN.

        (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 14 relating to adjustments upon changes
in securities and except as to amendments solely to benefit the administration
of the Plan, to take account of a change in legislation or to obtain or maintain
favorable tax, exchange control or regulatory treatment for Participants or the
Company or any Related Corporation, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary for the Plan to satisfy the requirements of Section 423 of the Code
or other applicable laws or regulations.

        (b) It is expressly contemplated that the Board may amend the Plan in
any respect the Board deems necessary or advisable to provide Employees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to Employee Stock Purchase Plans
and/or to bring the Plan and/or Purchase Rights granted under the Plan into
compliance therewith.

        (c) The rights and obligations under any Purchase Rights granted before
amendment of the Plan shall not be impaired by any amendment of the Plan except
(i) with the consent of the person to whom such Purchase Rights were granted,
(ii) as necessary to comply with any


                                      -10-


laws or governmental regulations, or (iii) as necessary to ensure that the Plan
and/or Purchase Rights granted under the Plan comply with the requirements of
Section 423 of the Code.

16.     TERMINATION OR SUSPENSION OF THE PLAN.

        (a) The Board in its discretion may suspend or terminate the Plan at any
time. Unless sooner terminated, the Plan shall terminate at the time that all of
the shares of Common Stock reserved for issuance under the Plan, as increased
and/or adjusted from time to time, have been issued under the terms of the Plan.
No Purchase Rights may be granted under the Plan while the Plan is suspended or
after it is terminated.

        (b) Any benefits, privileges, entitlements and obligations under any
Purchase Rights granted under the Plan while the Plan is in effect shall not be
impaired by suspension or termination of the Plan except (i) as expressly
provided in the Plan or with the consent of the person to whom such Purchase
Rights were granted, (ii) as necessary to comply with any laws, regulations, or
listing requirements, or (iii) as necessary to ensure that the Plan and/or
Purchase Rights granted under the Plan comply with the requirements of Section
423 of the Code.

17.     EFFECTIVE DATE OF PLAN.

        The Plan shall become effective as determined by the Board, but no
Purchase Rights granted under the Plan shall be exercised unless and until the
Plan has been approved by the stockholders of the Company within twelve (12)
months before or after the date the Plan is adopted by the Board.

18.     MISCELLANEOUS PROVISIONS.

        (a) The Plan and Offering do not constitute an employment contract.
