Offering Periods of six (6) months duration, other than the first Offering

                              (ii)      With respect to Offering Periods

than the Offering Period commencing on March 1, 2001, which shall have a
duration of approximately twenty-six (26) months and shall continue until April
30, 2003.

                              (iii)     The Plan shall continue until terminated
in accordance with Section 20 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 beginning
prior to March 1, 2001 shall have a six (6) month Purchase Period coincident
with such Offering Period.  Each Offering Period commencing on and after March
1, 2001 shall generally consist of four (4) consecutive Purchase Periods of six
(6) months’ duration commencing on May 1 and November 1 of each year, except the
first Offering Period commencing on March 1, 2001, which shall consist of five

Purchase Period commencing on May 1 shall end on the next October 31. A Purchase
Period commencing on November 1 shall end on the next April 30. 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 payroll office 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 Date of the Offering Period to which the subscription
agreement is applicable, unless the Employee’s participation is sooner
terminated 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 fifteen percent (15%) of such
participant’s Compensation on each payday during the Offering Period (or such
other maximum percentage as the Board may establish from time to time before an
Offering Date); provided that to the extent a participant is participating in
more than one Offering Period, the maximum aggregate percentage of Compensation
that he or she may contribute under the Plan shall be fifteen percent (15%) (or
such other maximum percentage as the Board may establish from time to time
before an Offering Date), and the participant’s earliest-filed subscription
agreement shall be reduced as necessary to prevent his or her Contributions in
the aggregate from exceeding such maximum percentage.  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.  In the case of Offering
Periods beginning prior to March 1, 2001, a participant may, on one occasion
only during the Offering Period, 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. 
In the case of Offering Periods beginning on and after March 1, 2001, a
participant may, on one occasion only during each Purchase Period, either
increase or decrease the rate of his or her Contributions with respect to the
Purchase Period by completing and filing with the Company a new subscription
agreement authorizing a change in the payroll deduction rate.  The change in
rate shall be effective as of the beginning of the next calendar month following
the date of filing of the new subscription agreement, if the agreement is filed
at least ten (10) business days prior to such date and, if not, as of the
beginning of the next succeeding calendar month.

                    (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 by the Company to 0% at any
time during an Offering or Purchase Period, as applicable.  Payroll deductions
shall re-commence at the rate provided in such participant’s subscription
agreement at the beginning of the first Offering or Purchase Period, as
applicable, which is scheduled to end in the following calendar year, unless the
participant’s participation is terminated as provided in Section 10.  In
addition, a participant’s payroll deductions may be decreased by the Company to
0% at any time during a Purchase Period in order to avoid unnecessary payroll
contributions as a result of application of the maximum Share limit set forth in
Section 7(a), or as a result of the limitations set forth in Section 3(b), in
which case payroll deductions shall re-commence at the rate provided in such
participant’s subscription agreement at the beginning of the next Purchase
Period, unless the participant’s participation is terminated as provided in
Section 10.

                    (d)      At the time the option is exercised, in whole or in
part, or at the time some or all of the Company's Common Stock issued under the
Plan is disposed of, the participant must make adequate provision for the
Company's federal, state, or other tax withholding obligations, if any, which
arise upon the exercise of the option or the disposition of the Common Stock. At
any time, the Company may, but shall not be obligated to, withhold from the
participant's compensation the amount necessary for the Company to meet
applicable withholding obligations, including any withholding required to make
available to the Company any tax deductions or benefits attributable to sale or
early disposition of Common Stock by the participant.

          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 occurring within the Offering Period a
number of Shares 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 (i) during
each Offering Period beginning prior to November 1, 2000, and (ii) during each
Purchase Period beginning on and after March 1, 2001, shall be in each case
1,000 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.  In the event an Employee participates in the
Offering Period beginning November 1, 2000 (the “November 2000 Offering Period”)
and in the Offering Period beginning March 1, 2001 (the “March 2001 Offering
Period”), on the applicable Purchase Date the Employee shall first be permitted
to purchase up to the 1,000 Share limit with respect to the November 2000
Offering Period and the Employee shall thereafter be permitted to purchase
Shares with respect to the March 2001 Offering Period to the extent the
aggregate number of Shares purchased with respect to the November 2000 Offering
Period and the March 2001 Offering Period on such Purchase Date do not exceed
the 1,000 Share limit described above.

                    (b)      The fair market value of the Company's Common Stock
on a given date (the “Fair Market Value”) means, as of any date, the value of
Common Stock determined by the Board in its discretion provided that, to the
extent the Common Stock is trading on the Nasdaq National Market (or a stock
exchange), (A) the Fair Market Value as of an Offering Date shall be the closing
sales price of the Common Stock as reported by the Nasdaq National Market (or
the closing sales price on such stock exchange) for the last business day
immediately preceding the Offering Date, and (B) the Fair Market Value of the
Common Stock as of a Purchase Date shall be the closing sales price of the
Common Stock as reported on the Nasdaq National Market (or the closing sales
price on such stock exchange) for the Purchase Date, in each case as reported in
The Wall Street Journal. For purposes of the Offering Date under the first
Offering Period under the Plan, the Fair Market Value of a Share shall be the
Price to Public as set forth in the final prospectus filed with the Securities
and Exchange Commission pursuant to Rule 424 under the Securities Act of 1933,
as amended.

          8.       Exercise of Option.

                    (a)      Unless a participant’s participation is terminated
as provided in Section 10, his or her option for the purchase of Shares will be
exercised automatically on each applicable 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 (subject to such limitations as are specified in the Plan). 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.

                    (b)      No fractional Shares shall be purchased.  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 termination of such participant’s participation 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.

          9.       Delivery.  As promptly as practicable after each Purchase
Date of each Offering Period, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate representing the Shares purchased
upon exercise of his or her option. Notwithstanding the foregoing, the Board may
require that all Shares purchased under the Plan be held in an account (the
participant’s “ESPP Stock Account”) established in the name of the participant
(or in the name of the participant and his or her spouse, as designated by the
participant on his or her subscription agreement), subject to such rules as
determined by the Board and uniformly applied to all participants, including
designation of a brokerage or other financial services firm (an “ESPP Broker”)
to hold such Shares for the participant’s ESPP Stock Account with registration
of such Shares in the name of such ESPP Broker for the benefit of the
participant or for the benefit of the participant and his or her spouse, as
designated by the participant on his or her subscription agreement.

          10.     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 under Section 15, 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 which the Employee is a participant,
unless such Employee is on an approved leave of absence or a temporary reduction
of hours, 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.  With respect to Offering Periods
commencing on and after March 1, 2001, and to the extent permitted by any
applicable laws, regulations or stock exchange rules, if the Fair Market Value
of the Shares on an Offering Date for an Offering Period (the “New Offering
Period”) commencing within an Offering Period (the “Ongoing Offering Period”)
then in progress, is lower than was the Fair Market Value of the Shares on the
Offering Date for the Ongoing Offering Period, then every participant in the
Ongoing Offering Period shall automatically be deemed to have (i) withdrawn from
the Ongoing Offering Period at the close of the Purchase Period immediately
preceding the New Offering Period, and (ii) to have enrolled in such New
Offering 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 500,000 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) 200,000 Shares, (ii) one percent (1.00%) 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.

                    (b)      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.

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

                    (d)      Shares to be delivered to a participant under the
Plan will be registered in the name of the participant or in the name of the
participant and his or her spouse, as designated by the participant in his or
her subscription agreement; provided that if the Board has determined that
Shares shall be held in an ESPP Stock Account held by an ESPP Broker in
accordance with Section 9, Shares shall be registered in the name of such ESPP
Broker for the benefit of the participant or the participant and his or her
spouse, as designated by the participant in his or her subscription agreement.

          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.     Designation of Beneficiary.

                    (a)      A participant may file a written designation of a
beneficiary who is to receive any Shares and cash, if any, from the
participant’s account under the Plan in the event of such participant’s death
subsequent to the end of a Purchase Period but prior to delivery to him or her
of such Shares and 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 prior to the
Purchase Date of an Offering Period.  If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                    (b)      Such designation of beneficiary may be changed by
the participant (and his or her spouse, if any) 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 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 discretion, may deliver such Shares 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.

          16.     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.

          17.     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.

          18.     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.

          19.     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) 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.

                    (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, or, if not so assumed or
substituted, the Offering Period then in progress shall be shortened and the
Board shall set a new Purchase Date (the “New Purchase Date”), as of which date
each Purchase Period and Offering Period then in progress will terminate.  The
New Purchase Date shall occur on or before the consummation of the Corporate
Transaction. If the Board shortens the Offering Period then in progress in lieu
of assumption or substitution in the event of a Corporate Transaction, the Board
will 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.

          20.     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, nor may an
amendment to the Plan make any change in any option previously granted which
adversely affects the rights of any participant (except as provided in Section
19 or this Section 20), provided that the Plan or a Purchase Period or an
Offering Period may be terminated or amended by the Board by the Board’s setting
a new Purchase Date with respect to a Purchase Period or an Offering Period then
in progress if the Board determines that termination or amendment of the Plan
and/or the Purchase Period and/or Offering Period is in the best interests of
the Company and the stockholders or if continuation of the Plan and/or the
Purchase Period and/or 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 accepted accounting rules applicable to the Plan.  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.

          21.     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.

          22.     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.

          23.     Term of Plan; Effective Date.  The Plan shall become effective
on May 6, 1999.  It shall continue in effect for a term of twenty (20) years
unless sooner terminated under Section 20.

          24.     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 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.

          1.       I, ________________________, hereby elect to participate in

for the Offering Period ______________, ____ to _______________, ____, and
subscribe to purchase Shares of the Company’s Common Stock in accordance with
this Subscription Agreement and the Plan.

          2.       I elect to have Contributions in the amount of ____% of my
Compensation, as those terms are defined in the Plan, applied to this purchase. 
I understand that this amount (together with any other amounts I am contributing
under the Plan) must not be less than 1% and not more than 15% of my
Compensation during the Offering Period.  (Please note that no fractional
percentages are permitted).

          3.       I hereby authorize payroll deductions from each paycheck
during the Offering Period at the rate stated in Item 2 of this Subscription
Agreement.  I understand that all payroll deductions made by me shall be
credited to my account under the Plan and that I may not make any additional
payments into such account.  I understand that all payments made by me shall be
accumulated for the purchase of Shares at the applicable purchase price
determined in accordance with the Plan.  I further understand that, except as
otherwise set forth in the Plan, Shares will be purchased for me automatically
on each Purchase Date of each Offering Period unless I otherwise withdraw from
the Plan by giving written notice to the Company for such purpose.

          4.       I understand that I may discontinue at any time prior to the
Purchase Date my participation in the Plan as provided in Section 10 of the
Plan.  I also understand that I can either increase or decrease the rate of my
Contributions on one occasion only during any Purchase Period by completing and
filing a new Subscription Agreement with such decrease taking effect as of the
beginning of the calendar month following the date of filing of the new
Subscription Agreement, if filed at least ten (10) business days prior to the
beginning of such month.  Further, I may change the rate of deductions for
future Offering Periods by filing a new Subscription Agreement, and any such
change will be effective as of the beginning of the next Offering Period.  In
addition, I acknowledge that, unless I discontinue my participation in the Plan
as provided in Section 10 of the Plan, my election will continue to be effective
for each successive Offering Period.

          5.       I have received a copy of the Company’s most recent
description of the Plan and a copy of the complete “Latitude Communications,
Inc. 1999 Employee Stock Purchase Plan.”  I understand that my participation in
the Plan is in all respects subject to the terms of the Plan.

the name(s) of (name of employee or employee and spouse only):

                                                  
____________________________________

                                                  
____________________________________

          7.       I understand that if I dispose of any shares received by me
pursuant to the Plan within 2 years after the Offering Date (the first day of
the Offering Period during which I purchased such shares) or within 1 year after
the Purchase Date, I will be treated for federal income tax purposes as having
received ordinary compensation income at the time of such disposition in an
amount equal to the excess of the fair market value of the shares on the
Purchase Date over the price which I paid for the shares, regardless of whether
I disposed of the shares at a price less than their fair market value at the
Purchase Date.  The remainder of the gain or loss, if any, recognized on such
disposition will be treated as capital gain or loss.

          I hereby agree to notify the Company in writing within 30 days after
the date of any such disposition, and I will make adequate provision for
federal, state or other tax withholding obligations, if any, which arise upon
the disposition of the Common Stock.  The Company may, but will not be obligated
to, withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to the sale or early
disposition of Common Stock by me.

          8.       If I dispose of such shares at any time after expiration of
the 2–year and 1–year holding periods, I understand that I will be treated for
federal income tax purposes as having received compensation income only to the
extent of an amount equal to the lesser of (1) the excess of the fair market
value of the shares at the time of such disposition over the purchase price
which I paid for the shares under the option, or (2) 15% of the fair market
value of the shares on the Offering Date.  The remainder of the gain or loss, if
any, recognized on such disposition will be treated as capital gain or loss.

          I understand that this tax summary is only a summary and is subject to
change.  I further understand that I should consult a tax advisor concerning the
tax implications of the purchase and sale of stock under the Plan.

          9.       I hereby agree to be bound by the terms of the Plan.  The
effectiveness of this Subscription Agreement is dependent upon my eligibility to
participate in the Plan.
