     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
Purchase Date of the Offering Period to which the subscription agreement is
applicable, unless sooner terminated by the participant as provided in Section
10.

     6.  METHOD OF PAYMENT OF CONTRIBUTIONS.
         ---------------------------------- 

         (a) A participant shall elect to have payroll deductions made on each
payday during the Offering Period in an amount not less than one percent (1%)
and not more than fifteen percent (15%) of such participant's compensation on
each payday during the Offering Period.  All payroll deductions made by a
participant shall be credited to his or her account under the Plan.  A
participant may not make any additional payments into such account.

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

                                      -3-

 
the new subscription agreement, if the agreement is filed at least ten (10)

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 during any Offering Period scheduled to end
during the current calendar year to 0%. Payroll deductions shall re-commence at
the rate provided in such participant's subscription agreement at the beginning
of the first Offering Period which is scheduled to end in the following calendar
year, unless terminated by the participant as provided in Section 10.

     7.   GRANT OF OPTION.
          --------------- 

          (a) On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Purchase Date a number of Shares of the Company's Common Stock
determined by dividing such Employee's Contributions accumulated prior to such
Purchase Date and retained in the participant's account as of the Purchase Date
by the applicable Purchase Price; provided however that the maximum number of
Shares an Employee may purchase during each Offering Period shall be 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.

          (b) The fair market value of the Company's Common Stock on a given
date (the "Fair Market Value") shall be determined by the Board in its
           -----------------                                          
discretion based on the closing sales price of the Common Stock for such date
(or, in the event that the Common Stock is not traded on such date, on the
immediately preceding trading date), as reported by the National Association of
Securities Dealers Automated Quotation (Nasdaq) National Market or, if such
price is not reported, the mean of the bid and asked prices per share of the
Common Stock as reported by Nasdaq or, in the event the Common Stock is listed
on a stock exchange, the Fair Market Value per share shall be the closing sales
price on such exchange on such date (or, in the event that the Common Stock is
not traded on such date, on the immediately preceding trading date), as reported
in The Wall Street Journal. For purposes of the Offering Date under the first
   -----------------------                                                    
Offering Period under the Plan, the Fair Market Value of a share of the Common
Stock of the Company 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.  Unless a participant withdraws from the Plan as
          ------------------                                                  
provided in Section 10, his or her option for the purchase of Shares will be
exercised automatically on the Purchase Date of an Offering Period, and the
maximum number of full Shares subject to the option will be purchased at the
applicable Purchase Price with the accumulated Contributions in his or her
account. No fractional Shares shall be issued. The Shares purchased upon
exercise of an option hereunder shall be deemed to be transferred to the
participant on the Purchase Date. During his or her lifetime, a participant's
option to purchase Shares hereunder is exercisable only by him or her.

     9.   DELIVERY.  As promptly as practicable after the Purchase Date of each
          --------                                                             
Offering Period, the Company shall arrange the delivery to each participant, as
appropriate, of a certificate 

                                      -4-

 
representing the Shares purchased upon exercise of his or her option. 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 Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 below. Any other amounts left over in a
participant's account after a Purchase Date shall be returned to the
participant.

     10.  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
the 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 14, 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, 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.  INTEREST.  No interest shall accrue on the Contributions of a
          --------                                                     
participant in the Plan.

     12.  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.  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

                                      -5-

 
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 19 below. The Company may make pro
rata allocation of the Shares available on the Offering Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional Shares for issuance under the Plan by the Company's
stockholders subsequent to such Offering Date.

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

          (c) 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.

     13.  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. The composition of the committee shall be in accordance with the
requirements to obtain or retain any available exemption from the operation of
Section 16(b) of the Exchange Act pursuant to Rule 16b-3 promulgated thereunder.

     14.  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 an
Offering 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, 

                                      -6-

 
or if no spouse, dependent or relative is known to the Company, then to such
other person as the Company may designate.

     15.  TRANSFERABILITY.  Neither Contributions credited to a participant's
          ---------------                                                    
account nor any rights with regard to the exercise of an option or to receive
Shares under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 14) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds in accordance with Section 10.

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

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

     18.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS.
          ------------------------------------------------------------------ 

          (a) ADJUSTMENT.  Subject to any required action by the stockholders of
              ----------                                                        
the Company, the number of Shares covered by each option under the Plan which
has not yet been exercised and the number of Shares which have been authorized
for issuance under the Plan but have not yet been placed under option
(collectively, the "Reserves"), the maximum number of shares of Common Stock
                    --------                                                
which may be purchased by a participant in an Offering Period, the number of
shares of Common Stock set forth in Section 12(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, the 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, unless the Board determines, in the exercise of its sole discretion

                                      -7-

 
and in lieu of such assumption or substitution, to shorten the Offering Period
then in progress by setting a new Purchase Date (the "New Purchase Date").  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 18, 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 18); provided however that if the consideration received in the
transaction is not solely common stock of the successor corporation or its
parent (as defined in Section 424(e) of the Code), the Board may, with the
consent of the successor corporation, provide for the consideration to be
received upon exercise of the option to be solely common stock of the successor
corporation or its parent equal in Fair Market Value to the per Share
consideration received by holders of Common Stock in the transaction.

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

     19.  AMENDMENT OR TERMINATION.
          ------------------------ 

          (a) The Board may at any time and for any reason terminate or amend
the Plan.  Except as provided in Section 18, 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, provided that the Plan or an Offering Period may be terminated
or amended by the Board by the Board's setting a new Purchase Date with respect
to an Offering Period then in progress if the Board determines that termination
or amendment of the Plan and/or the Offering Period is in the best interests of
the Company and the stockholders or if continuation of the Plan and/or the
Offering Period would cause the Company to incur adverse accounting charges as a
result of a change after the effective date of the Plan in the generally
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.

                                      -8-

 
          (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, limit the
frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

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

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

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

     22.  TERM OF PLAN; EFFECTIVE DATE.  The Plan shall become effective upon
          ----------------------------                                       
the IPO Date.  It shall continue in effect for a term of twenty (20) years
unless sooner terminated under Section 19.

     23.  ADDITIONAL RESTRICTIONS OF RULE 16B-3.  The terms and conditions of
          -------------------------------------                              
options granted hereunder to, and the purchase of Shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3.  This Plan shall be 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 the
Latitude Communications, Inc. 1999 Employee Stock Purchase Plan (the "Plan") 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 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 of Common Stock 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 the 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 increase or decrease the rate of my Contributions on one
occasion only with respect to any increase and one occasion only with respect to
any decrease during an Offering Period by completing and filing a new
Subscription Agreement with such increase or 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.

     6.  Shares purchased for me under the Plan should be issued in the name(s)
of (name of employee or employee and spouse only):

                                         ____________________________________
          
                                         ____________________________________

     7.  In the event of my death, I hereby designate the following as my
beneficiary(ies) to receive all payments and shares due to me under the Plan:



NAME:  (Please print)              _____________________________________
                                    (First)       (Middle)        (Last)

_____________________              _____________________________________

                                   _____________________________________

     8.  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.

     9.  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 

                                      -2-

 
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.

     10. 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.
