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 limitations of, the express provisions of the Plan:

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

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

            (iii) To construe and interpret the Plan and Rights granted under
it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in 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 paragraph 14.

            (v) To terminate or suspend the Plan as provided in paragraph 16.

            (vi) 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 Affiliates 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, all of the members of which
Committee may be, in the discretion of the Board, Non-Employee Directors and/or
Outside Directors. 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, including the power to delegate to a



                                       3.
<PAGE>   4
subcommittee of two (2) or more Outside Directors any of the administrative
powers the Committee is authorized to exercise (and references in this Plan to
the Board shall thereafter be to the Committee or such a subcommittee), 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.

4.      SHARES SUBJECT TO THE PLAN.

        (a) Subject to the provisions of paragraph 13 relating to adjustments
upon changes in securities, the shares of the Common Stock that may be sold
pursuant to Rights granted under the Plan shall not exceed in the aggregate five
hundred thousand (500,000) shares of the Common Stock (the "Reserved Shares").
As of each January 1, beginning on January 1, 2002, and continuing through and
including January 1, 2010, the number of Reserved Shares will be increased
automatically by the lesser of (i) one percent (1%) of the total number of
shares of the Common Stock outstanding on such January 1 or (ii) two hundred
fifty thousand (250,000) shares. Notwithstanding the foregoing, the Board may
designate a smaller number of shares to be added to the share reserve as of a
particular January 1. If any Right granted under the Plan shall for any reason
terminate without having been exercised, the shares of the Common Stock not
purchased under such Right shall again become available for the Plan.

        (b) The shares of the Common Stock subject to the Plan may be unissued
shares of the Common Stock or shares of the Common Stock that have been bought
on the open market at prevailing market prices or otherwise.

5.      GRANT OF RIGHTS; OFFERING.

        The Board may from time to time grant or provide for the grant of Rights
to purchase shares of the Common Stock under the Plan to Eligible Employees in
an Offering on an Offering Date or 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 requirements of Section
423(b)(5) of the Code that all Employees granted Rights to purchase shares of
the 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 paragraphs 6 through 9, inclusive.

6.      ELIGIBILITY.

        (a) Rights may be granted only to Employees of the Company or, as the
Board may designate as provided in subparagraph 3(b), to Employees of an
Affiliate. Except as provided in subparagraph 6(b), an Employee shall not be
eligible to be granted Rights under the Plan unless, on the Offering Date, such
Employee has been in the employ of the Company or the Affiliate, as the case may
be, for such continuous period preceding such grant as the Board may require,
but



                                       4.
<PAGE>   5

in no event shall the required period of continuous employment be less than
ninety (90) days or equal to or greater than two (2) years; provided, however,
that Employees who are employed by the Company as of the Effective Date of this
Plan who would otherwise be Eligible Employees if not for the required period of
continuous employment with the Company shall be eligible to participate in the
Plan with respect to the first Offering Period without regard to their period of
prior continuous employment with the Company provided that they remain in
continuous employment through the end of the first Offering Period.

        (b) The Board may provide that each person who, during the course of an
Offering, first becomes an Eligible Employee will, 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 Right under that
Offering, which Right shall thereafter be deemed to be a part of that Offering.
Such Right shall have the same characteristics as any Rights originally granted
under that Offering, as described herein, except that:

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

            (ii) the period of the Offering with respect to such 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 will not receive any Right under that Offering.

        (c) No Employee shall be eligible for the grant of any Rights under the
Plan if, immediately after any such 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 Affiliate. For purposes of this
subparagraph 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 rights and options shall be treated as stock
owned by such Employee.

        (d) An Eligible Employee may be granted Rights under the Plan only if
such Rights, together with any other Rights granted under all Employee Stock
Purchase Plans of the Company and any Affiliates, as specified by Section
423(b)(8) of the Code, do not permit such Eligible Employee's rights to purchase
shares of the Common Stock or any Affiliate to accrue at a rate which exceeds
twenty five thousand dollars ($25,000) of the fair market value of such shares
of the Common Stock (determined at the time such Rights are granted) for each
calendar year in which such Rights are outstanding at any time.

        (e) 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.      RIGHTS; PURCHASE PRICE.

        (a) On each Offering Date, each Eligible Employee, pursuant to an
Offering made under the Plan, shall be granted the Right to purchase up to the
number of shares of the Common Stock purchasable either:

            (i) with a percentage designated by the Board not exceeding fifteen
percent (15%) of such Employee's Earnings (as defined by the Board in each
Offering) during the period which 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; or

            (ii) with a maximum dollar amount designated by the Board that, as
the Board determines for a particular Offering, (1) shall be withheld, in whole
or in part, from such Employee's Earnings (as defined by the Board in each
Offering) during the period which 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 and/or (2) shall be contributed, in whole or in part, by such Employee
during such period.

        (b) The Board shall establish one or more Purchase Dates during an
Offering on which Rights granted under the Plan shall be exercised and purchases
of shares of the Common Stock 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 the Common Stock that may be purchased by
any Participant as well as a maximum aggregate number of shares of the 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 the Common
Stock which may be purchased by all Participants on any given Purchase Date
under the Offering. If the aggregate purchase of shares of the Common Stock upon
exercise of Rights granted under the Offering would exceed any such maximum
aggregate amount, the Board shall make a pro rata allocation of the shares of
the Common Stock available in as nearly a uniform manner as shall be practicable
and as it shall deem to be equitable.

        (d) The purchase price of shares of the Common Stock acquired pursuant
to Rights granted under the Plan shall be not less than the lesser of:

            (i) an amount equal to eighty-five percent (85%) of the fair market
value of the shares of the Common Stock on the Offering Date; or

            (ii) an amount equal to eighty-five percent (85%) of the fair market
value of the shares of the Common Stock on the Purchase Date.

8.      PARTICIPATION; WITHDRAWAL; TERMINATION.

        (a) An Eligible Employee may become a Participant in the Plan pursuant
to an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company provides. Each such
agreement shall authorize payroll



                                       6.
<PAGE>   7

deductions of up to the maximum percentage specified by the Board of such
Employee's Earnings during the Offering (as defined in each Offering). The
payroll deductions made for each Participant shall be credited to a bookkeeping
account for such Participant under the Plan and either may be deposited with the
general funds of the Company or may be deposited in a separate account in the
name of, and for the benefit of, such Participant with a financial institution
designated by the Company. To the extent provided in the Offering, a Participant
may reduce (including to zero) or increase such payroll deductions. To the
extent provided in the Offering, a Participant may begin such payroll deductions
after the beginning of the Offering. A Participant may make additional payments
into his or her account only if specifically provided for in the Offering and
only if the Participant has not already had the maximum permitted amount
withheld during the Offering.

        (b) At any time during an Offering, a Participant may terminate his or
her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board 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 payroll deductions (reduced to the
extent, if any, such deductions have been used to acquire shares of the Common
Stock for the Participant) under the Offering, without interest unless otherwise
specified in the Offering, and such Participant's interest in that Offering
shall be automatically terminated. A Participant's withdrawal from an Offering
will have no effect upon such Participant's eligibility to participate in any
other Offerings under the Plan but such Participant will be required to deliver
a new participation agreement in order to participate in subsequent Offerings
under the Plan.

        (c) Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating Employee's employment
with the Company or a designated Affiliate for any reason (subject to any
post-employment participation period required by law) or other lack of
eligibility. The Company shall distribute to such terminated Employee all of his
or her accumulated payroll deductions (reduced to the extent, if any, such
deductions have been used to acquire shares of the Common Stock for the
terminated Employee) under the Offering, without interest unless otherwise
specified in the Offering. If the accumulated payroll deductions have been
deposited with the Company's general funds, then the distribution shall be made
from the general funds of the Company, without interest. If the accumulated
payroll deductions have been deposited in a separate account with a financial
institution as provided in subparagraph 8(a), then the distribution shall be
made from the separate account, without interest unless otherwise specified in
the Offering.

        (d) 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 paragraph 15 and, otherwise during
his or her lifetime, shall be exercisable only by the person to whom such Rights
are granted.

9.      EXERCISE.

        (a) On each Purchase Date specified therefor in the relevant Offering,
each Participant's accumulated payroll deductions and other additional payments
specifically



                                       7.
<PAGE>   8

provided for in the Offering (without any increase for interest) will be applied
to the purchase of shares of the Common Stock up to the maximum number of shares
of the 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 of the Common Stock shall be issued upon the exercise of
Rights granted under the Plan unless specifically provided for in the Offering.

        (b) Unless otherwise specifically provided in the Offering, the amount,
if any, of accumulated payroll deductions remaining in any Participant's account
after the purchase of shares of the Common Stock that is equal to the amount
required to purchase one or more whole shares of the Common Stock on the final
Purchase Date of the Offering shall be distributed in full to the Participant at
the end of the Offering, without interest. If the accumulated payroll deductions
have been deposited with the Company's general funds, then the distribution
shall be made from the general funds of the Company, without interest. If the
accumulated payroll deductions have been deposited in a separate account with a
financial institution as provided in subparagraph 8(a), then the distribution
shall be made from the separate account, without interest unless otherwise
specified in the Offering. The amount of accumulated payroll deductions
remaining in any Participant's account that is less than the amount required to
purchase one whole share of Common Stock on the final Purchase Date of the
Offering shall be carried over to the next Offering or shall, if the Participant
requests or does not participate in the next Offering, be refunded.

        (c) No Rights granted under the Plan may be exercised to any extent
unless the shares of the Common Stock to be issued upon such exercise under the
Plan (including Rights granted thereunder) are covered by an effective
registration statement pursuant to the Securities Act and the Plan is in
material compliance with all applicable state, foreign and other securities and
other laws applicable to the Plan. If on a Purchase Date in any Offering
hereunder the Plan is not so registered or in such compliance, no Rights granted
under the Plan or any Offering shall be exercised on such Purchase Date, and the
Purchase Date shall be delayed until the Plan is subject to such an effective
registration statement and 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 of any Offering hereunder, as delayed to the maximum extent
permissible, the Plan is not registered and in such compliance, no Rights
granted under the Plan or any Offering shall be exercised and all payroll
deductions accumulated during the Offering (reduced to the extent, if any, such
deductions have been used to acquire Shares) shall be distributed to the
Participants, without interest unless otherwise specified in the Offering. If
the accumulated payroll deductions have been deposited with the Company's
general funds, then the distribution shall be made from the general funds of the
Company, without interest. If the accumulated payroll deductions have been
deposited in a separate account with a financial institution as provided in
subparagraph 8(a), then the distribution shall be made from the separate
account, without interest unless otherwise specified in the Offering.

10.     COVENANTS OF THE COMPANY.

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



                                       8.
<PAGE>   9

        (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 the Common Stock upon
exercise of the Rights granted under the Plan. If, after reasonable efforts, the
Company is unable to obtain from any such regulatory commission or agency the
authority which counsel for the Company deems necessary for the lawful issuance
and sale of shares of the Common Stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell shares of the Common
Stock upon exercise of such Rights unless and until such authority is obtained.

11.     USE OF PROCEEDS FROM SHARES.

        Proceeds from the sale of shares of the Common Stock pursuant to 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 the Common Stock subject to
Rights granted under the Plan unless and until the Participant's shares of the
Common Stock acquired upon exercise of Rights under the Plan are recorded in the
books of the Company.

13.     ADJUSTMENTS UPON CHANGES IN SECURITIES.

        (a) If any change is made in the shares of the Common Stock subject to
the Plan, or subject to any 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 will be appropriately adjusted in the
class(es) and maximum number of shares of the Common Stock subject to the Plan
pursuant to subparagraph 4(a), and the outstanding Rights will be appropriately
adjusted in the class(es), number of shares of the Common Stock and purchase
limits of such outstanding 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 that
does not involve the receipt of consideration by the Company.)

        (b) In the event of: (i) a dissolution, liquidation, or sale of all or
substantially all of the assets of the Company; (ii) a merger or consolidation
in which the Company is not the surviving corporation; or (iii) a reverse merger
in which the Company is the surviving corporation but the shares of the Common
Stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise, then: (1) any surviving or acquiring corporation may assume Rights
outstanding under the Plan or may substitute similar rights (including a right
to acquire the same consideration paid to the Company's stockholders in the
transaction described in this subparagraph 13(b)) for those outstanding under
the Plan, or (2) in the event any surviving or acquiring corporation does not
assume such Rights or substitute similar rights for those outstanding under the
Plan, then, as determined by the Board in its sole discretion, such Rights



                                       9.
<PAGE>   10

may continue in full force and effect or the Participants' accumulated payroll
deductions (exclusive of any accumulated interest which cannot be applied toward
the purchase of shares of the Common Stock under the terms of the Offering) may
be used to purchase shares of the Common Stock immediately prior to the
transaction described above under the ongoing Offering and the Participants'
Rights under the ongoing Offering thereafter terminated.

14.     AMENDMENT OF THE PLAN.

        (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in paragraph 13 relating to adjustments upon changes
in securities and except as to minor amendments 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 Affiliate, 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, Rule 16b-3
under the Exchange Act and any Nasdaq or other securities exchange listing
requirements. Currently under the Code, stockholder approval within twelve (12)
months before or after the adoption of the amendment is required where the
amendment will:

            (i) Increase the number of shares of the Common Stock reserved for
Rights under the Plan;

            (ii) Modify the provisions as to eligibility for participation in
the Plan to the extent such modification requires stockholder approval in order
for the Plan to obtain employee stock purchase plan treatment under Section 423
of the Code or to comply with the requirements of Rule 16b-3; or

            (iii) Modify the Plan in any other way if such modification requires
stockholder approval in order for the Plan to obtain employee stock purchase
plan treatment under Section 423 of the Code or to comply with the requirements
of Rule 16b-3.

        (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 Rights granted under it into compliance
therewith.

        (c) Rights and obligations under any Rights granted before amendment of

                                    OFFERING

                            ADOPTED FEBRUARY 15, 2000
                     APPROVED BY STOCKHOLDERS JULY 10, 2000


1.      GRANT; OFFERING DATE.

        (a) The Board of Directors (the "Board") of Repeater Technologies, Inc.
(the "Company"), pursuant to the Company's Employee Stock Purchase Plan (the
"Plan"), hereby authorizes the grant of rights to purchase shares of the common
stock of the Company ("Common Stock") to all Eligible Employees (an "Offering").
The first Offering shall begin on the effective date of the initial public
offering of the Company's Common Stock and end on October 31, 2002 (the "Initial
Offering"). Further, an Offering shall begin on each May 1 and November 1
thereafter, commencing on November 1, 2000, and shall end on the day prior to
the second anniversary of each such Offering's Offering Date unless sooner
terminated in accordance with the provisions of this Offering or the Plan. The
first day of an Offering is that Offering's "Offering Date."

        (b) Notwithstanding the foregoing: (i) if any Offering Date falls on a
day that is not a Trading Day (as defined herein), then such Offering Date shall
instead fall on the next subsequent Trading Day and (ii) if any Purchase Date
falls on a day that is not a Trading Day, then such Purchase Date shall instead
fall on the immediately preceding Trading Day. "Trading Day" shall mean any day
the exchange(s) or market(s) on which the Common Stock is listed, whether it be
any established stock exchange, The Nasdaq National Market, The Nasdaq SmallCap
Market or otherwise, is open for trading.

        (c) Except as provided in paragraph 4, "Fair Market Value" shall mean
the closing sales price for the Common Stock (or the closing bid price, if no
sales were reported) as quoted on any established stock exchange or traded on
the Nasdaq National Market or the Nasdaq SmallCap Market and as reported in The
Wall Street Journal or such other source as the Board deems reliable.

        (d) Prior to the commencement of any Offering, the Board (or the
Committee described in subparagraph 2(c) of the Plan, if any) may change any or
all terms of such Offering and any subsequent Offerings. The granting of rights
pursuant to each Offering hereunder shall occur on each respective Offering Date
unless, prior to such date (a) the Board (or the Committee) determines that such
Offering shall not occur, or (b) no shares remain available for issuance under
the Plan in connection with the Offering.

        (e) Notwithstanding any other provisions of an Offering, if the terms of
an Offering as previously established by the Board would, as a result of a
change to applicable accounting standards, as a result of obtaining shareholder
approval during such Offering for shares of Common Stock that would be issued
under such Offering (but for the provisions of this Section 1(e)), or otherwise,
generate a charge to earnings, such Offering shall terminate effective as of the
earlier of (1) the day prior to the date such change of accounting standards
would otherwise



                                       1.

first apply to the Offering or (2) the day prior to the date upon which the
maximum aggregate number of shares of Common Stock available to be purchased by
all Eligible Employees under such Offering (excluding any additional shares of
Common Stock made available for issuance under the Plan by approval of the
shareholders of the Company during the Offering) exceeds the aggregate number of
whole shares purchasable by all Eligible Employees based upon the aggregate of
such Employees' payroll deductions accumulated pursuant to such Offering (the
"Offering Termination Date"), and such Offering Termination Date shall be the
final Purchase Date of such Offering. A subsequent Offering shall commence on
such date and on such terms as shall be provided by the Board of Directors of
the Company.

2.      ELIGIBLE EMPLOYEES.

        (a) All employees of the Company and each of its Affiliates (as defined
in the Plan) incorporated in the United States, shall be granted rights to
purchase Common Stock under each Offering on the Offering Date of such Offering,
provided that each such employee otherwise meets the employment requirements of
subparagraph 5(a) of the Plan (an "Eligible Employee"), provided, however, that
otherwise eligible employees with the Company who are employed by the Company on
the date of the Company's initial public offering will be eligible to
participate in the Plan as of the Initial Offering if they remain in employment
with the Company through the relevant Purchase Date of the initial Offering
Period.

        Notwithstanding the foregoing, the following employees shall not be
Eligible Employees or be granted rights under an Offering: (i) part-time or
seasonal employees whose customary employment is less than twenty (20) hours per
week or five (5) months per calendar year and (ii) 5% stockholders (including
ownership through unexercised and/or unvested stock options) described in
subparagraph 5(c) of the Plan.

        (b) Notwithstanding the foregoing, each person who first becomes an
Eligible Employee during any Offering and at least six (6) months prior to the
final Purchase Date (as defined in paragraph 6 hereof) of the Offering will, on
the next May 1 or November 1 during that Offering coinciding with or immediately
following the date that person first becomes an Eligible Employee, receive a
right under such Offering, which right shall thereafter be deemed to be a part
of the Offering. Such right shall have the same characteristics as any rights
originally granted under the Offering except that:

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

           (2) the Offering for such right shall begin on its Offering Date and
end coincident with the end of the ongoing Offering.

3.      RIGHTS.

        (a) Subject to the limitations contained herein and in the Plan, on each
Offering Date each Eligible Employee shall be granted the right to purchase the
number of shares of Common Stock purchasable with up to fifteen percent (15%) of
such employee's Earnings paid during the period of such Offering beginning after
such Eligible Employee first commences participation; provided, however, that no
employee may purchase Common Stock on a particular Purchase



                                       2.
<PAGE>   14

Date that would result in more than fifteen percent (15%) of such employee's
Earnings in the period from the Offering Date to such Purchase Date having been
applied to purchase shares under all ongoing Offerings under the Plan and all
other plans of the Company intended to qualify as "employee stock purchase
plans" under Section 423 of the Internal Revenue Code of 1986, as amended (the
"Code"). For this Offering, "Earnings" means the base salary paid to an employee
(including all amounts elected to be deferred by the employee, that would
otherwise have been paid, under any cash or deferred arrangement established by
the Company), overtime pay, commissions, and bonuses, but excluding other
remuneration paid directly to the employee, profit sharing, the cost of employee
benefits paid for by the Company, education or tuition reimbursements, imputed
income arising under any Company group insurance or benefit program, traveling
expenses, business and moving expense reimbursements, income received in
connection with stock options, contributions made by the Company under any
employee benefit plan, and similar items of compensation.

        (b) Notwithstanding the foregoing, the maximum number of shares of
Common Stock an Eligible Employee may purchase on any Purchase Date in an
Offering shall be such number of shares as has a Fair Market Value (determined
as of the Offering Date for such Offering) equal to (x) $25,000 multiplied by
the number of calendar years in which the right under such Offering has been
outstanding at any time, minus (y) the Fair Market Value of any other shares of
Common Stock (determined as of the relevant Offering Date with respect to such
shares) which, for purposes of the limitation of Section 423(b)(8) of the Code,
are attributed to any of such calendar years in which the right is outstanding.
The amount in clause (y) of the previous sentence shall be determined in
accordance with regulations applicable under Section 423(b)(8) of the Code based
on (i) the number of shares previously purchased with respect to such calendar
years pursuant to such Offering or any other Offering under the Plan, or
pursuant to any other Company plans intended to qualify as "employee stock
purchase plans" under Section 423 of the Code, and (ii) the number of shares
subject to other rights outstanding on the Offering Date for such Offering
pursuant to the Plan or any other such Company plan.

        (c) The maximum aggregate number of shares available to be purchased by
all Eligible Employees under an Offering shall be the number of shares remaining
available under the Plan on the Offering Date. If the aggregate purchase of
shares of Common Stock upon exercise of rights granted under the Offering would
exceed the maximum aggregate number of shares available, the Board shall make a
pro rata allocation of the shares available in a uniform and equitable manner.

4.      PURCHASE PRICE.

        The purchase price of the Common Stock under the Offering shall be the
lesser of: (i) eighty-five percent (85%) of the Fair Market Value of the Common
Stock on the Offering Date or (ii) or eighty-five percent (85%) of the Fair
Market Value of the Common Stock on the Purchase Date, in each case rounded up
to the nearest whole cent per share. For the Initial Offering, the Fair Market
Value of the Common Stock at the time when the Offering commences shall be the
price per share at which shares of Common Stock are first sold to the public in
the Company's initial public offering as specified in the final prospectus with
respect to that public offering.

5.      PARTICIPATION.

        (a) An Eligible Employee may elect to participate in an Offering only at
the beginning of the Offering, or such later date specified in subparagraph
2(b). An Eligible Employee may become a participant in an Offering by
delivering an enrollment form authorizing payroll deductions. Such deductions
must be either a fixed dollar amount per pay period, up to a maximum dollar
amount which is less than or equal to fifteen percent (15%) of Earnings, or in
whole percentages of Earnings, with a minimum percentage of one percent (1%) and
a maximum percentage of fifteen percent (15%). A participant may not make
additional payments into his or her account. The agreement shall be made on such
enrollment form as the Company provides, and must be delivered to the Company
prior to the date participation is to be effective, unless a later time for
filing the enrollment form is set by the Company for all Eligible Employees with
respect to a given Offering. For the Initial Offering, the time for filing an
enrollment form and commencing participation for individuals who are Eligible
Employees on the Offering Date for the Initial Offering shall be determined by
the Company and communicated to such Eligible Employees.

        (b) A participant may decrease his or her participation level during the
course of a six (6) month purchase interval one (1) time, and only by delivering
notice to the Company at least ten (10) days in advance of the Purchase Date in
such form as the Company prescribes; provided that a participant may (i) reduce
his or her deductions to zero percent (0%) upon ten (10) days' prior notice, or
within such shorter period as determined by the Board and communicated to the
participants, by delivering a notice in such form as the Company provides, (ii)
may increase or decrease his or her participation level at any time to become
effective on the day following the next subsequent Purchase Date, or (iii) may
withdraw from an Offering and receive his or her accumulated payroll deductions
from the Offering (reduced to the extent, if any, such deductions have been used
to acquire Common Stock for the participant on any prior Purchase Dates) without
interest, at any time prior to the end of the Offering, excluding only each ten
(10) day period immediately preceding a Purchase Date, by delivering a
withdrawal notice to the Company in such form as the Company provides. A
participant who has withdrawn from an Offering shall not again participate in
such Offering, but may participate in subsequent Offerings under the Plan in
accordance with the terms thereof.

6.      PURCHASES.

        Subject to the limitations contained herein, on each Purchase Date, each
participant's accumulated payroll deductions (without any increase for interest)
shall be applied to the purchase of whole shares of Common Stock, up to the
maximum number of shares permitted under the Plan and the Offering. "Purchase
Date" shall be defined as each April 30 and October 31 within the Offering. The
Purchase Dates under the Initial Offering shall be April 30 and October 31 of
the year 2001 and April 30 and October 31 of the year 2002. Notwithstanding the
foregoing, if any Purchase Date falls on a day that is not a Trading Day, then
such Purchase Date shall instead fall on the immediately preceding Trading Day.
On a Purchase Date, each participant's purchases will first be made under the
Offering, for which purchases are made on such date, that results in stock being
purchased for such participant at the lowest price under all Offerings in which
such participant then has been granted rights and under which stock is purchased
on such Purchase Date.
