                                  ARTICLE III

          Eligibility; Types of Benefits; Shares Subject to the Plan
          ----------------------------------------------------------

     3.1  Criteria.  The Committee shall from time to time determine and
          --------
designate the Participants to receive Benefits under the Plan and the number of
Options to be awarded to such persons; provided, however, that only Employees
may be designated to receive Incentive Stock Options; and provided further,
however, that no Benefits may be received by a Consultant under this Plan for
services rendered in connection with the offer and sale of securities in a
capital-raising transaction. In making any such awards, the Committee may take
into account the nature of services rendered, commissions or other compensation
earned, the capacity of the Employee, Consultant, Officer or Director to
contribute to the success of the Company or any of its Affiliates, and such
other factors as the Committee may consider relevant.

     3.2  Types of Benefits.  Benefits available under the Plan may be awarded
          -----------------
singularly or in any combination provided, however, that Incentive Stock Options
may not be awarded in tandem with Nonstatutory Stock Options where the exercise
of one affects the right to exercise the other.

     3.3  Shares Subject to the Plan.  Stock that may be issued under the Plan
          --------------------------
shall be authorized and unissued Common Stock.  The maximum total number of
shares of Common Stock which may be issued under the Plan shall be fifteen
million (15,000,000) shares.  For purposes of calculating the maximum number of
shares of Common Stock that may be issued under the Plan:

                                    Page 5
<PAGE>

     (a)  The Common Stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise;

     (b)  when cash is used by the Participant as full payment for shares issued
upon exercise of a Non-Statutory Stock Option or an Incentive Stock Option, all
the shares issued (including the shares, if any, withheld for tax withholding
requirements) shall be counted; and

     (c)  when shares of stock, including, without limitation, Common Stock
issued pursuant to the Plan, are used by the Participant as full or partial
payment for shares issued upon exercise of a Non-Statutory Stock Option or an
Incentive Stock Option, all the shares issued (including shares, if any,
withheld for tax withholding requirements, and the shares used in the purchase)
shall be counted; and

     (d)  any shares of Common Stock subject to a Non-Statutory Stock Option or
an Incentive Stock Option which for any reason is terminated unexercised or
expires shall again be available for issuance under the Plan.

     3.4  Ten Percent Shareholders.  No Employee shall be eligible to receive an
          ------------------------
Incentive Stock Option if such Employee owns, or is deemed to beneficially own
under Section 424(d) of the Code, stock possessing more than ten percent (10%)
of the total combined voting power of all classes of stock of the Company or of
any of its Affiliates, unless (i) the option price is at least one hundred ten
percent (110%) of the Fair Market Value of the Common Stock as the time the
Option is granted; and (ii) the Option is not exercisable after the expiration
of five (5) years (or such shorter period as the Committee may determine).

     3.5  Rule 701 Limitation.  It is intended that this Plan shall comply with
          -------------------
Rule 701 of the Securities Act of 1933, as amended.  Therefore, the aggregate
exercise price of the outstanding stock options of the Company plus the
aggregate offering price of securities of the Company offered or sold in the
preceding 12 months in reliance on Rule 701 shall not exceed the greater of
$500,000 or the amount determined under clause (a) or (b) below; provided,
however, that the aggregate exercise price of the outstanding stock options of
the Company plus the aggregate offering price of securities of the Company
offered or sold in the preceding 12 months in reliance on Rule 701 shall in no
event exceed $5,000,000.

     (a)  The aggregate exercise price of outstanding stock options of the
Company plus the aggregate offering price of securities of the Company offered
or sold in the preceding 12 months in reliance on Rule 701 shall not exceed 15%
of the total assets of the Company measured at the end of its last fiscal year;
or

     (b)  The aggregate number of shares of Common Stock for which outstanding
stock options of the Company may be exercised plus the aggregate number of
shares of Common Stock of the Company offered or sold in the preceding twelve
months in reliance on Rule 701 shall not exceed 15% of the number of outstanding
shares of Common Stock.  The outstanding shares of Common Stock shall include
securities of that class issuable pursuant to the exercise of outstanding
options, warrants, rights or conversion of convertible securities, unless such
options, warrants, rights or convertible securities were issued under Rule 701.
If the securities offered or sold under Rule 701 are convertible securities, the
number of securities subject to outstanding offers and sold under this clause
shall be deemed to be shares of the securities into which such securities may be
converted.

                                    Page 6
<PAGE>

The Committee shall ensure compliance with the restrictions set forth in Rule
701, as shall be in effect from time to time.  In furtherance of this objective,
the Committee shall maintain a record of shares subject to outstanding stock
options of the Company and the exercise price of such options, plus a record of
all shares of Common Stock issued upon the exercise of such options and the
exercise price of such options.  If the Company offers securities under any
other compensatory benefit plan or written contract relating to compensation
under Rule 701, the Board shall take such steps as are required to ensure that
the shares offered and sold under this Plan and such other securities do not
exceed the limitations of Rule 701.

                                  ARTICLE IV

                            Incentive Stock Options
                            -----------------------

     Incentive Stock Options granted pursuant to this Article are intended to
constitute "incentive stock options" under Section 422 of the Code.  No Employee
may be granted Incentive Stock Options under this Plan if the aggregate Fair
Market Value (determined as of the date the Option is granted and taking into
account such Option) of stock of the Company and its Affiliates with respect to
which incentive stock options (as defined in Section 422 of the Code) are
exercisable for the first time by such Employee during any calendar year, under
this and all other plans of the Company and its Affiliates, would exceed one
hundred thousand dollars ($100,000).

     The Incentive Stock Option Agreements shall contain terms and provisions
determined by the Committee and consistent with this Plan.  The Committee from
time to time may grant Incentive Stock Options to Employees under this Plan,
which grants shall be evidenced by Incentive Stock Option Agreements.

     4.1  Mandatory Provisions.  The Incentive Stock Option Agreements may be
          --------------------
need not be identical, but each such Incentive Stock Option Agreement shall
include, by appropriate language, the substance of all the following terms and
provisions:

     (a)  That the Option granted thereunder is an Incentive Stock Option.

     (b)  The number of shares to which it pertains.

     (c)  A minimum number of the shares that may be purchased upon each partial
exercise of an Option.

     (d)  The option exercise price, which price shall be set by the Committee
and shall be equal to one hundred percent (100%) of the Fair Market Value of the
Common Stock at the time the Option is granted; provided, however, that for an
Employee who is a ten percent shareholder, as determined in Paragraph 3.4, the
option price for the Option shall be at least one hundred ten percent (110%) of
the Fair Market Value of the Common Stock at the time the Option is granted.

     (e)  The date the Option is granted, which shall be the date selected by
the Committee as of which the Committee allots a specific number of shares of
Common Stock to an Employee pursuant to the Plan.

     (f)  The time after which the Option expires, provided that the Option
shall not be exercisable after the expiration of ten (10) years from the date it
is granted and that with respect to

                                    Page 7
<PAGE>

an employee who is a ten percent shareholder, as determined in Paragraph 3.4,
the Option shall not be exercisable after the expiration of five (5) years from
the date it is granted.

     (g)  That the Option terminates upon termination of employment of the
Employee with either the Company or an Affiliate, except as such period may be
extended under the optional provisions in Paragraph 4.2.

     (h)  That the Option is exercisable during the Optionee's lifetime only by
the Optionee, and that the Option shall not be assignable or transferable by the
Optionee except by will or distribution through intestate succession.

     (i)  That neither Optionee, nor any person to whom an Option is permitted
to be transferred, shall be deemed to be the holder of, or have any rights of a
holder with respect to, any shares subject to such Option unless and until such
person has satisfied all requirements for exercise of the Option, pursuant to
its terms, and then only after shares have been issued to Optionee.

     (j)  The time and medium of payment with respect to exercise of the Option,
provided that if payment is permitted to be made by Common Stock, the stock
shall be valued at its Fair Market Value as of the date the Option is exercised.

     (k)  Unless modified by the optional provisions in Paragraph, 4.2, that to
the extent the Employee (or other person exercising such Option) recognizes
income as a result of the exercise of the Option, the subsequent sale of the
Common Stock issued pursuant to exercise of the Option, or a lapse in the
restrictions on the Restricted Stock issued upon exercise of the Option, then
the Employee shall pay the Company or such Affiliate an amount equal to the
federal, state and local withholding taxes on income so recognized at the time
required by law.

     (l)  The treatment of the Options upon merger, reorganization,
recapitalization, exchange of shares, change in corporate structure,
liquidation, stock dividend and similar events.

     (m)  If the Company is a Reporting Company, a term providing that any
Common Stock acquired upon exercise of the Option shall not be sold or otherwise
transferred before the expiration of six (6) months from the date such Option is
granted.

     4.2  Optional Provisions.  Incentive Stock Option Agreements may contain
          -------------------
such other provisions not inconsistent with the Plan and Section 422 of the Code
as the Committee, in its discretion, deems advisable. Without limiting the
foregoing, the Committee may consider inclusion of the following terms:

     (a)  That upon termination of Employee's employment with the Company of its
Affiliates other than as a result of death or disability the Option may be
exercised for an additional period of time, as specified by the Committee but
not to exceed ninety (90) days.

     (b)  That upon termination of Employee's employment with the Company of its
Affiliates as a result of death the Option may be exercised for an additional
period of time, as specified by the Committee but not to exceed one (1) year.

     (c)  That upon termination of Employee's employment with the Company of its
Affiliates as a result of disability (within the meaning of Section 22(e)(3) of
the Code and as defined in the

                                    Page 8
<PAGE>

Incentive Stock Option Agreement) the Option may be exercised for an additional
period of time, as specified by the Committee but not to exceed one (1) year.

     (d)  That the Optionee be prohibited from transferring any share of stock
issued upon exercise of an Option within two (2) years from the date of the
granting of the Option or within one (1) year after the transfer of such share
to the Optionee.

     (e)  That the total number of shares of stock subject to an Option shall be
allotted in periodic installments (which may, but need not, be equal) and that
from time to time during each of such installment periods, the Option shall
become exercisable ("vest") with respect to some or all of the shares allotted
to that period, and may be exercised with respect to some or all of the shares
allocated to such period and/or any prior period as to which the Option became
vested but was not fully exercised.  The Option may be subject to such other
terms and conditions on the time or times when it may be exercised (which may be
based on performance or other criteria) as the Committee may deem appropriate.

     (f)  The circumstances under which all or any portion of any Option granted
and not yet vested may or shall have the vesting schedule accelerated or
terminated.

     (g)  The circumstances under which all or any portion of any Option
previously granted and unexercised may or shall be  terminated.

     (h)  That the shares to be received upon exercise shall be Restricted Stock
and that no exercise of an Option shall be effective until the Restricted Stock
Agreement has been executed with respect to such shares.

     (i)  That in the event an Employee accepting a grant of Options under this
Plan incurs federal, state or local income, employment or other withholding

     5.2  Optional Provisions.  Non-Statutory Stock Option Agreements may
          -------------------

in its discretion, shall deem advisable.  Without limiting the foregoing, the
Committee shall specifically consider inclusion of the following terms:

     (a)  That the total number of shares of stock subject to an Option be
allotted in periodic installments (which may, but need not, be equal) and that
from time to time during each of such installment periods, the Option may become
exercisable ("vest") with respect to some or all of the shares allotted to that
period, and may be exercised with respect to some or all of the shares allocated
to such period and/or any prior period as to which the Option became vested but
was not fully exercised. The Option may be subject to such other terms and
conditions on the time or times when it may be exercised (which may be based on
performance or other criteria) as the Committee may deem appropriate.

     (b)  The circumstances under which all or any portion of any Option
previously granted and unexercised may or shall be  terminated, including
without limitation expiration of the Option as it may be related to termination

this Plan incurs federal, state or local income, employment or other withholding
taxes applicable to the income recognized by such Participant and attributable
to the Common Stock issued upon exercise of the Option, the subsequent sale of
the Common Stock issued pursuant to exercise of the Option, or a lapse of the
restrictions on the Restricted Stock, then at the time as may be required by
law, the Company or its applicable Affiliate may provide for payment of the
taxes on behalf of the Participant (or other person exercising such Option)
pursuant to one or any combination of the following: (i) by an advance on behalf
of Participant by the Company or such Affiliate pursuant to a repayment schedule
satisfactory to the Company or such Affiliate; or (ii) by withholding from the
Participant's salary, commissions or other compensation; or (iii) by payment in
whole or in part by the Company or such Affiliate.

     5.3  Prohibited Provision.  No Non-Statutory Stock Option Agreement shall
          --------------------
impose an obligation on the Optionee to exercise an Option.

                                  ARTICLE VI

                           Miscellaneous Provisions
                           ------------------------

     6.1  Right to Terminate Employment.  Nothing in this Plan shall confer upon
          -----------------------------

affect any right which the Company or any Affiliate may have to terminate the
employment of such Participant.

                                    Page 11
<PAGE>

     6.2  Securities Laws.  Each Benefit awarded under the Plan shall be subject
          ---------------
to the requirement that, if at any time the Committee shall determine that (i)
the listing, registration or qualification of the shares of Common Stock subject
to the Plan upon any securities exchange or under any state or federal law, or
(ii) the consent or approval of any governmental authority, or (iii) an
agreement by the recipient of an award with respect to the disposition of shares
of Common Stock, is necessary or desirable as a condition of, or in connection
with, the granting of such Benefit or the issue or purchase of shares of Common
Stock thereunder, the award of such Benefit may not be consummated in whole or
in part unless such listing, registration, qualification, consent, approval or
agreement shall have been effected or obtained free of any conditions not
acceptable to the Committee. The inability of the Company to obtain from any
regulatory body having jurisdiction the authority deemed by the Company's
counsel to be necessary to the lawful issuance of any shares of its Common Stock
hereunder shall relieve the Company of any liability in respect of the non-
issuance or sale of such stock as to which such requisite authority shall not
have been obtained. Notwithstanding the foregoing, the Company shall not be
required to register under the Securities Act any Option or any Common Stock to
be issued under the Plan or pursuant to the exercise of any Option.

     6.3  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------
shall at all times reserve and keep available, and will seek or obtain from any
regulatory body having jurisdiction any requisite authority in order to issue
such number of shares of its Common Stock as shall be sufficient to satisfy the
requirements of the Plan.

     6.4  Indemnification of Committee.  In addition to such other rights of
          ----------------------------
indemnification as they may have as Directors or as members of the Committee,
the members of the Committee shall be indemnified by the Company against the
reasonable expenses, including attorneys' fees actually and necessarily incurred
in connection with the defense of any action, suit or proceeding, or in
connection with any appeal therein, to which they or any of them may be a party
by reason of any action taken or failure to act under or in connection with the
Plan or any Benefit granted under the Plan, and against all amounts paid by them
in settlement thereof (provided such settlement is approved by independent legal
counsel selected by the Company) or paid by them in satisfaction of a judgment
in any such action, suit or proceeding, except in relation to matters as to
which it shall be adjudged in such action, suit or proceeding that such
Committee member is liable for gross negligence or wilful misconduct in the
performance of his duties, provided that within sixty (60) days after
institution of any such action, suit or proceeding, a Committee member shall
have offered the Company, in writing, the opportunity, at its own expense, to
handle and defend the same.

     6.5  Amendment, Modification, Suspension or Discontinuance of the Plan.
          -----------------------------------------------------------------
The Board, without shareholder approval, may from time to time alter, amend,
suspend or terminate this Plan for the purpose of improving the effectiveness of
the Plan as an incentive device, or conforming the Plan to applicable
governmental regulations or to any change in applicable law or regulations, or
any other purpose permitted by law; provided, however, that no such action by
the Board shall adversely affect any Benefit theretofore granted under the Plan
without the consent of the holder so affected; provided further that the Board
may not increase the number of shares of Common Stock authorized under Paragraph
3.3 of this Plan without the approval of the shareholders of the Company; and
provided further that the Board shall submit any amendments to the shareholders
of the Company for approval to the extent necessary to maintain compliance with
the requirements of Rule 16b-3 under the Exchange Act; and provided further that
if the Company is a reporting Company and Benefits are awarded in accordance
with a formula as described in Rule 16b-3(2)(i) of the Exchange Act, then the
formula provisions may not be amended more than once every six months, other
than to comport with changes in the Internal Revenue Code, the Employee

maintain the qualification of the Incentive Stock Options that may be granted
hereunder as an incentive stock options within the meaning of Section 422 of the
Code.

     6.6  Use of Proceeds.  Proceeds from the sale of stock pursuant to Options
          ---------------
shall constitute general funds of the Company.

     6.7  Governing Law.  This Plan and all rights and obligations hereunder
          -------------
shall be construed in accordance with and governed by the internal laws of the
State of North Carolina.

          -----------
instruments as the "HAHT Commerce, Inc. 1995 Stock Award Plan".

                                                                    EXHIBIT 10.2

                              HAHT COMMERCE, INC.

                       2000 EMPLOYEE STOCK PURCHASE PLAN

     1.   Purpose.  The HAHT Commerce, Inc. 2000 Employee Stock Purchase Plan
          -------
(the "Plan") is established to provide eligible employees of HAHT Commerce,
Inc., a North Carolina corporation, and any successor corporation thereto
(collectively, "HAHT" or the "Company"), and any current or future parent
corporation or subsidiary corporations of HAHT as the Board of Directors of HAHT
(the "Board") shall from time to time designate (collectively referred to as the
"Company" and individually referred to as a "Participating Company"), with an
opportunity to acquire a proprietary interest in the Company by the purchase of
common stock of HAHT. For purposes of the Plan, a parent corporation and a
subsidiary corporation shall be as defined in sections 424(e) and 424(f),
respectively, of the Internal Revenue Code of 1986, as amended (the "Code").

     HAHT intends that the Plan shall qualify as an "employee stock purchase
plan" under section 423 of the Code (including any amendments or replacements of
such section), and the Plan shall be so construed.  Any term not expressly
defined in the Plan but defined for purposes of section 423 of the Code shall
have the same definition herein.

     An employee participating in the Plan (a "Participant") may withdraw such
Participant's accumulated payroll deductions (if any) and terminate
participation in the Plan or any Offering (as defined below) therein at any time
during an Offering Period (as defined below).  Accordingly, each Participant is,
in effect, granted an option pursuant to the Plan (a "Purchase Right") at the
beginning of an Offering Period (as defined below) that may or may not be
exercised at the end of the Offering Period.

     2.   Administration.  The Plan shall be administered by a duly appointed
          --------------
committee (the "Committee") of the Board having such powers as shall be
specified by the Board. All questions of interpretation of the Plan or of any
Purchase Right shall be determined by the Committee and shall be final and
binding upon all persons having an interest in the Plan and/or any Purchase
Right.  Subject to the provisions of the Plan, the Committee shall determine all
of the relevant terms and conditions of Purchase Rights granted pursuant to the
Plan; provided, however, that all Participants granted Purchase Rights pursuant
      --------  -------
to the Plan shall have the same rights and privileges within the meaning of
section 423(b)(5) of the Code.  All expenses incurred in connection with the
administration of the Plan shall be paid by the Company.

     3.   Share Reserve.  The maximum number of shares that may be issued under
          -------------
the Plan shall be _________________________ (__________) shares of HAHT's
authorized but unissued common stock, ____ par value (the "Shares"); provided,
                                                                     --------
however, that the Company shall have the authority to purchase shares of its
-------
issued common stock on the Nasdaq National Market, or on such other national or
regional markets on which such shares are being traded, to satisfy its
obligations under the Plan.  Any shares purchased by the Company pursuant to
this Paragraph 3 shall reduce the share reserve set forth above by a
corresponding amount.  In the
<PAGE>

event that any Purchase Right for any reason expires or is canceled or
terminated, the Shares allocable to the unexercised portion of such Purchase
Right may again be subjected to a Purchase Right.

     4.   Eligibility.  Any employee of a Participating Company is eligible to
          -----------
participate in the Plan except employees who:

          (a)  customarily work less than 20 hours per week;

          (b)  customarily work not more than five months in any calendar year;
or

          (c)  as of the start of an Offering, own stock of HAHT (or its parent
or subsidiary corporations) and/or own or hold options to purchase or who, as a
result of participation in the Plan, would own or hold options to purchase,
stock of HAHT (or its parent or subsidiary corporations), possessing five
percent (5%) or more of the total combined voting power or value of all classes
of stock of HAHT (or its parent or subsidiary corporations) within the meaning
of section 423(b)(3) of the Code.

     Notwithstanding anything herein contained to the contrary, any individual
performing services for a Participating Company solely through a leasing agency
or employment agency shall not be deemed an "employee" of such Participating
Company.

     5.   Offering Dates.
          --------------

          (a)  Offering Periods.  Except as otherwise set forth below, the Plan
               ----------------
shall be implemented by offerings ("Offerings", individually, an "Offering") of
approximately six (6) months duration (each an "Offering Period").  The "Initial
Offering Date" is the date immediately preceding the effective date of a
registration statement filed with the Securities and Exchange Commission
relating to an initial public offering of HAHT's securities.  The Initial
Offering Period shall commence on the Initial Offering Date and shall end on the
last day of the sixth full calendar month following the calendar month during
which the Initial Offering Date occurred.  Subsequent Offering Periods of six
full calendar months duration shall commence thereafter on the day immediately
following the ending of an Offering Period.  Notwithstanding the foregoing, the
Committee may establish a different term for one or more Offerings and/or
different commencing and/or ending dates for such Offerings; provided, however,
                                                             --------  -------
that the Initial Offering Period must exceed six (6) calendar months.  An
employee who becomes eligible to participate in the Plan after an Offering
Period has commenced shall not be eligible to participate in such Offering but
may participate in any subsequent Offering provided such employee is still
eligible to participate in the Plan as of the commencement of any such
subsequent Offering.  Eligible employees may not participate in more than one
Offering at a time.  The first day of an Offering Period shall be the "Offering
Date" for such Offering Period.  In the event the first and/or last day of an
Offering Period is not a business day, HAHT shall specify the business day that
will be deemed the first or last day, as the case may be, of the Offering
Period.

          (b)  Purchase Periods.  Each Offering Period, except for the Initial
               ----------------
Offering Period, shall consist of one (1) purchase period of six (6) months
duration (a "Purchase Period"),

                                       2
<PAGE>

which shall run concurrently with the Offering Period. The last day of each
Purchase Period shall be the "Purchase Date" for such Purchase Period. The
Initial Offering Period shall consist of one (1) Purchase Period that commences
on the Initial Offering Date and ends on the date determined by the Committee to
be the ending date for the Initial Offering Period. Notwithstanding the
foregoing, the Committee may establish a different term for one or more Purchase
Periods and/or different commencing dates and/or Purchase Dates for such
Purchase Periods; provided, however, that the Purchase Period of the Initial
                  --------  -------
Offering Period must exceed six (6) calendar months. In the event the first
and/or last day of a Purchase Period is not a business day, HAHT shall specify
the business day that will be deemed the first or last day, as the case may be,
of the Purchase Period.

          (c)  Governmental Approval; Stockholder Approval.  Notwithstanding any
               -------------------------------------------
other provision of the Plan to the contrary, any Purchase Right granted pursuant
to the Plan shall be subject to (i) obtaining all necessary governmental
approvals and/or qualifications of the sale and/or issuance of the Purchase
Rights and/or the Shares, and (ii) obtaining stockholder approval of the Plan.
Notwithstanding the foregoing, stockholder approval shall not be necessary in
order to grant any Purchase Right granted in the Plan's Initial Offering Period;
provided, however, that the exercise of any such Purchase Right shall be subject
to obtaining stockholder approval of the Plan.

     6.   Participation in the Plan.
          -------------------------

          (a)  Initial Participation.  An eligible employee shall become a
               ---------------------
Participant on the first Offering Date after satisfying the eligibility
requirements and delivering to the Company's payroll office not later than the
close of business for such payroll office on the last business day before such
Offering Date (the "Subscription Date") a subscription agreement indicating the
employee's election to participate in the Plan and authorizing payroll
deductions.  An eligible employee who does not deliver a subscription agreement
to the Company's payroll office on or before the Subscription Date shall not
participate in the Plan for that Offering Period or for any subsequent Offering
Period unless such employee subsequently enrolls in the Plan by filing a
subscription agreement with the Company by the Subscription Date for such
subsequent Offering Period.  The Company may, from time to time, change the
Subscription Date as deemed advisable by the Company in its sole discretion for
proper administration of the Plan.

          (b)  Continued Participation.  A Participant shall automatically
               -----------------------
participate in the Offering Period commencing immediately after the Purchase
Date of each Offering Period in which the Participant participates until such
time as such Participant (i) ceases to be eligible as provided in paragraph 4,
(ii) withdraws from the Plan pursuant to paragraph 11(b) or (iii) terminates
employment as provided in paragraph 12.  If a Participant may participate
automatically in a subsequent Offering Period pursuant to this paragraph 6(b),
then the Participant is not required to file any additional subscription
agreement for such subsequent Offering Period in order to continue participation
in the Plan.  However, a Participant may file a subscription agreement with
respect to a subsequent Offering Period if the Participant desires to change any
of the Participant's elections contained in the Participant's then effective
subscription agreement.

                                       3
<PAGE>

7.   Right to Purchase Shares.  Except as set forth below, during an Offering
     ------------------------
Period each Participant in such Offering Period shall have a Purchase Right
consisting of the right to purchase up to that number of whole Shares arrived at
by dividing Twelve Thousand Five Hundred Dollars ($12,500.00) by the fair market
value of a share of the common stock of HAHT on the Offering Date of such
Offering Period.

          The fair market value of Shares shall be determined in accordance with
paragraph 8 below.  Shares may only be purchased through a Participant's payroll
withholding pursuant to paragraph 9 below.  In no event shall a Participant's
Purchase Right permit such Participant to acquire more Shares in any calendar
year than is permitted under Section 10(a) hereof.

     8.   Purchase Price.  The purchase price at which Shares may be acquired in
          --------------
a given Purchase Period pursuant to the exercise of all or any portion of a
Purchase Right granted under the Plan (the "Offering Exercise Price") shall be
set by the Committee; provided, however, that the Offering Exercise Price shall
                      --------  -------
not be less than eighty-five percent (85%) of the lesser of (i) the fair market
value of the Shares on the Offering Date of the Offering Period of which the
Purchase Period is a part, or (ii) the fair market value of the Shares on the
Purchase Date for such Purchase Period; provided, however that the fair market
                                        --------  -------
value of the Shares on the Initial Offering Date shall be deemed to be the
initial public offering price of HAHT's Common Stock.  Unless otherwise provided
by the Committee prior to the commencement of an Offering Period, the Offering
Exercise Price for each Purchase Period in that Offering Period shall be eighty-
five percent (85%) of the lesser of (i) the fair market value of the Shares on
the Offering Date of such Offering Period or (ii) the fair market value of the
Shares on the given Purchase Date.  The fair market value of the Shares on the
applicable dates shall be the closing sales price on the Nasdaq National Market
(or the average of the closing bid and asked prices if the Shares are so quoted
instead) or as reported on such other national or regional securities exchange
or market system if the Shares are traded on such other exchange or system
instead, or as determined by the Committee if the Shares are not so reported.
If the relevant date does not fall on a day on which the common stock of HAHT is
quoted on the Nasdaq National Market or such other national or regional
securities exchange or market, the date on which the fair market value per Share
shall be established shall be the last day on which the common stock of HAHT was
so quoted to such relevant date.

     9.   Payment of Purchase Price.  Shares which are acquired pursuant to the
          -------------------------
exercise of all or any portion of a Purchase Right may be paid for only by means
of payroll deductions from the Participant's Compensation during the Offering
Period.  For purposes of the Plan, a Participant's "Compensation" with respect
to an Offering (i) shall include the Participant's base salary before deduction
for any contributions to any plan maintained by a Participating Company and
described in section 401(k) or section 125 of the Code, commissions, overtime
and bonuses and (ii) shall not include annual awards, other incentive payments,
shift premiums, long-term disability, worker's compensation or any other
payments not specifically referenced in (i).  Except as set forth below, the
amount of Compensation to be withheld from a Participant's

                                       4
<PAGE>

Compensation during each pay period shall be determined by the Participant's
subscription agreement.

          (a)  Election to Decrease, Increase or Stop Withholding.  During an
               --------------------------------------------------
Offering Period, a Participant may elect to decrease the amount withheld, or
stop withholding, from his or her Compensation by filing as amended subscription
agreement with the Company on or before the "Change Notice Date."  The "Change
Notice Date" shall initially be the seventh (7th) day prior to the end of the
first pay period for which such election is to be effective; however, the
Company may change such Change Notice Date from time to time.  A Participant may
elect to increase the amount withheld from the Participant's Compensation once
during any Purchase Period.  A Participant's election during a Purchase Period
to increase the amount withheld from his or her compensation shall be effective
on a prospective basis only and shall not be retroactive to the beginning of the
Purchase Period.

          (b)  Limitations on Payroll Withholding.  The amount of payroll
               ----------------------------------
withholding with respect to the Plan for any Participant during any pay period
shall be in one percent (1%) increments not to exceed fifteen percent (15%) of
the Participant's Compensation for such pay period; provided, however, that the
                                                    --------  -------
Committee may increase or decrease the limits on allowable payroll withholding
for any Offering Period, including the Initial Offering Period, prior to the
Offering Date of such Offering Period.  Amounts withheld shall be reduced by any
amounts contributed by the Participant and applied to the purchase of Company
stock pursuant to any other employee stock purchase plan qualifying under
section 423 of the Code.

          (c)  Payroll Withholding.  Payroll deductions shall commence on the
               -------------------
first payday following the Offering Date and shall continue to the end of the
Offering Period unless sooner altered or terminated as provided in the Plan.

          (d)  Participant Accounts.  Individual accounts shall be maintained
               --------------------
for each Participant. All payroll deductions from a Participant's Compensation
shall be credited to such account and shall be deposited with the general funds
of the Company. All payroll deductions received or held by the Company may be
used by the Company for any corporate purpose.

          (e)  No Interest Paid.  Interest shall not be paid on sums withheld
               ----------------
from a Participant's Compensation, unless the Committee elects to make such
payments to all Participants on a non-discriminatory basis.

          (f)  Exercise of Purchase Right.  On the Purchase Date of an Offering
               --------------------------
Period, each Participant who has not withdrawn from the Offering or whose
participation in the Offering has not terminated on or before such Purchase Date
shall automatically acquire pursuant to the exercise of the Participant's
Purchase Right the number of whole Shares arrived at by dividing the total
amount of the Participant's accumulated payroll deductions for the Purchase
Period by the Offering Exercise Price; provided, however, in no event shall the
                                       --------  -------
number of Shares purchased by the Participant exceed the number of Shares
subject to the Participant's Purchase Right or the limitations imposed by
Section 10(a) hereof.  No Shares shall be purchased on a Purchase Date on behalf
of a Participant whose participation in the Offering or the Plan has terminated
on or before such Purchase Date.

                                       5
<PAGE>

          (g)  Return of Cash Balance.  Any cash balance remaining in the
               ----------------------
Participant's account shall be refunded to the Participant as soon as
practicable after the Purchase Date.  In the event the cash to be returned to a
Participant pursuant to the preceding sentence is an amount less than the amount
necessary to purchase a whole Share, the Company may establish procedures
whereby such cash is maintained in the Participant's account and applied toward
the purchase of Shares in the subsequent Purchase Period or Offering Period.

          (h)  Tax Withholding.  At the time the Purchase Right is exercised, in
               ---------------
whole or in part, or at the time some or all of the Shares are disposed of, the
Participant shall make adequate provision for the foreign, federal, state and
local employment and withholding tax obligations of the Company, if any, which
arise upon exercise of the Purchase Right and/or upon disposition of Shares,
respectively.  The Company may, but shall not be obligated to, withhold from the
Participant's Compensation the amount necessary to meet such withholding
obligations.

          (i)  Committee Established Procedures.  The Committee may, from time
               --------------------------------
to time, establish or change (i) a minimum required withholding amount for
participation in an Offering, (ii) limitations on the frequency and/or number of
changes in the amount withheld during an Offering, (iii) an exchange ratio
applicable to amounts withheld in a currency other than U.S. dollars, (iv)
payroll withholding in excess of or less than the amount designated by a
Participant in order to adjust for delays or mistakes in the Company's
processing of subscription agreements, (v) the date(s) and manner by which the
fair market value of the Shares is determined for purposes of administration of
the Plan and/or (vi) such other limitations or procedures as deemed advisable by
the Committee in the Committee's sole discretion which are consistent with the
Plan and in accordance with the requirements of section 423 of the Code.

          (j)  Expiration of Purchase Right.  Any portion of a Participant's
               ----------------------------
Purchase Right remaining unexercised after the end of the Offering Period to
which such Purchase Right relates shall expire immediately upon the end of such
Offering Period.

     10.  Limitations on Purchase of Shares; Rights as a Stockholder.
          ----------------------------------------------------------

          (a)  Fair Market Value Limitation.  Notwithstanding any other
               ----------------------------
provision of the Plan, no Participant shall be entitled to purchase Shares under
the Plan (and under all other employee stock purchase plans which are intended
to meet the requirements of section 423 of the Code sponsored by the Company or
a parent or subsidiary corporation of the Company) at a rate which exceeds
$25,000 in fair market value, which fair market value is determined for Shares
purchased during a given Offering Period as of the Offering Date for such
Offering Period (or such other limit as may be imposed by the Code), for each
calendar year in which such Participant's Purchase Right with respect to such
Offering Period remains outstanding under the Plan (and under all other employee
stock purchase plans described in this sentence).

          (b)  Pro Rata Allocation.  In the event the number of Shares which
               -------------------
might be purchased by all Participants in the Plan exceeds the number of Shares
available in the Plan, the Committee shall make a pro rata allocation of the
remaining Shares in as uniform a manner as shall be practicable and as the
Committee shall determine to be equitable.

                                       6
<PAGE>

          (c)  Rights as a Stockholder and Employee.  A Participant shall have
               ------------------------------------
no rights as a stockholder by virtue of the Participant's participation in the
Plan until the date of the issuance of a stock certificate(s) for the Shares
being purchased pursuant to the exercise of the Participant's Purchase Right. No
adjustment shall be made for cash dividends or distributions or other rights for
which the record date is prior to the date such stock certificate(s) are issued.
Nothing herein shall confer upon a Participant any right to continue in the
employ of the Company or interfere in any way with any right of the Company to
terminate the Participant's employment at any time.

     11.  Withdrawal.
          ----------

          (a)  Withdrawal From an Offering.  A Participant may withdraw from an
               ---------------------------
Offering by signing and delivering to the Company's payroll office, a written
notice of withdrawal on the form provided by the Company for such purpose.  Such
withdrawal may be elected at any time prior to the end of an Offering Period.
Unless otherwise indicated, withdrawal from an Offering shall not result in a
withdrawal from the Plan or any succeeding Offering therein.  A Participant is
prohibited from again participating in an Offering at any time upon withdrawal
from such Offering.  The Company may impose, from time to time, a requirement
that the notice of withdrawal be on file with the Company's payroll office for a
reasonable period prior to the effectiveness of the Participant's withdrawal
from an Offering.

          (b)  Withdrawal from the Plan.  A Participant may withdraw from the
               ------------------------
Plan by signing a written notice of withdrawal on a form provided by the Company
for such purpose and delivering such notice to the Company's payroll office.
Withdrawals made after a Purchase Date for an Offering Period shall not affect
Shares acquired by the Participant on such Purchase Date.  In the event a
Participant voluntarily elects to withdraw from the Plan, the Participant may
not resume participation in the Plan during the same Offering Period, but may
participate in any subsequent Offering under the Plan by again satisfying the
requirements of paragraphs 4 and 6(a) above.  The Company may impose, from time
to time, a requirement that the notice of withdrawal be on file with the
Company's payroll office for a reasonable period prior to the effectiveness of
the Participant's withdrawal from the Plan.

          (c)  Return of Payroll Deductions.  Upon withdrawal from an Offering
               ----------------------------
or the Plan pursuant to paragraphs 11(a) or 11(b), respectively, the withdrawn
Participant's accumulated payroll deductions which have not been applied toward
the purchase of Shares shall be returned as soon as practicable after the
withdrawal, without the payment of any interest (unless the Committee decides
otherwise pursuant to paragraph 9(e) above), to the Participant, and the
Participant's interest in the Offering and/or the Plan, as applicable, shall
terminate. Such accumulated payroll deductions may not be applied to any other
Offering under the Plan.

     12.  Termination of Employment.  Termination of a Participant's employment
          -------------------------
with the Company for any reason, including retirement, disability or death or
the failure of a Participant to remain an employee eligible to participate in
the Plan, shall terminate the Participant's participation in the Plan
immediately.  In such event, the payroll deductions credited to the
Participant's account since the last Purchase Date shall, as soon as
practicable, be returned to the

                                       7
<PAGE>

Participant or, in the case of the Participant's death, to the Participant's
legal representative, and all of the Participant's right under the Plan shall
terminate. Interest shall not be paid on sums returned to a Participant pursuant
to this paragraph 12 unless the Committee elects otherwise pursuant to paragraph
9(e) above. A Participant whose participation has been so terminated may again
become eligible to participate in the Plan by again satisfying the requirements
of paragraphs 4 and 6(a) above.

     13.  Transfer of Control.  A "Transfer of Control" shall be deemed to have
          -------------------
occurred in the event any of the following occurs with respect to HAHT.

          (a)  a merger or consolidation in which HAHT is not the surviving
corporation;

          (b)  a merger or consolidation in which HAHT is the surviving
corporation where the stockholders of HAHT before such merger or consolidation
do not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of HAHT;

          (c)  the sale, exchange, or transfer of all or substantially all of
HAHT's assets other than a sale, exchange, or transfer to one (1) or more
subsidiary corporations (as defined in section 1, above) of HAHT;

          (d)  the direct or indirect sale or exchange by the stockholders of
HAHT of all or substantially all of the stock of HAHT where the stockholders of
HAHT before such sale or exchange do not retain, directly or indirectly, at
least a majority of the beneficial interest in the voting stock of HAHT after
such sale or exchange; or

          (e)  the liquidation or dissolution of HAHT;

          In the event of a Transfer of Control, the Committee, in its sole
discretion, may arrange with the surviving, continuing, successor, or purchasing
corporation, as the case may be (the "Acquiring Corporation"), for the Acquiring
Corporation to assume HAHT's rights and obligations under the Plan.  All
Purchase Rights shall terminate effective as of the date of the Transfer of
Control to the extent that the Purchase Right is neither exercised as of the
date of the Transfer of Control nor assumed by the Acquiring Corporation.

     14.  Capital Changes.  In the event of changes in the common stock of HAHT
          ---------------
due to a stock split, reverse stock split, stock dividend, recapitalization,
combination, reclassification, or like change in HAHT's capitalization, or in
the event of any merger (including a merger effected for the purpose of changing
HAHT's domicile), sale or other reorganization, appropriate adjustments shall be
made by HAHT in the securities subject to purchase under a Purchase Right, the
Plan's share reserve, the number of Shares subject to a Purchase Right, and in
the purchase price per Share.

     15.  Transferability.  A Purchase Right may not be transferred in any
          ---------------
manner otherwise than by will or the laws of descent and distribution and shall
be exercisable during the lifetime of the Participant only by the Participant.
HAHT, in its absolute discretion, may impose

                                       8
<PAGE>

such restrictions on the transferability of the Shares purchasable upon the
exercise of a Purchase Right as it deems appropriate, and any such restriction
shall be set forth in the respective subscription agreement and may be referred
to on the certificates evidencing such Shares.

     16.  Reports.  Each Participant who exercised all or part of his or her
          -------
Purchase Right for a Purchase Period shall receive, as soon as practicable after
the Purchase Date of such Purchase Period, a report of such Participant's
account setting forth the total payroll deductions accumulated, the number of
Shares purchased, the fair market value of such Shares, the date of purchase and
the remaining cash balance to be refunded or retained in the Participant's
account pursuant to paragraph 9(g) above, if any.  In addition, each Participant
shall be provided information concerning HAHT equivalent to that information
generally made available to HAHT's common stockholders.

     17.  Plan Term.  This Plan shall continue until terminated by the Board or
          ---------
until all of the Shares reserved for issuance under the Plan have been issued.

     18.  Restriction on Issuance of Shares.  The issuance of Shares under the
          ---------------------------------
Plan shall be subject to compliance with all applicable requirements of foreign,
federal or state law with respect to such securities.  A Purchase Right may not
be exercised if the issuance of Shares upon such exercise would constitute a
violation of any applicable foreign, federal or state securities laws or other
law or regulations.  In addition, no Purchase Right may be exercised unless (i)
a registration statement under the Securities Act of 1933, as amended, shall at
the time of exercise of the Purchase Right be in effect with respect to the
Shares issuable upon exercise of the Purchase Right, or (ii) in the opinion of
legal counsel to HAHT, the Shares issuable upon exercise of the Purchase Right
may be issued in accordance with the terms of an applicable exemption from the
registration requirements of said Act. As a condition to the exercise of a
Purchase Right, HAHT may require the Participant to satisfy any qualifications
that may be necessary or appropriate, to evidence compliance with any applicable
law or regulation, and to make any representation or warranty with respect
thereto as may be requested by the Company.

     19.  Legends.  The Company may at any time place legends or other
          -------
identifying symbols referencing any applicable foreign, federal and/or state
securities restrictions or any provision convenient in the administration of the
Plan on some or all of the certificates representing Shares issued under the
Plan.  The Participant shall, at the request of HAHT, promptly present to HAHT
any and all certificates representing Shares acquired pursuant to a Purchase
Right in the possession of the Participant in order to carry out the provisions
of this subparagraph.  Unless otherwise specified by HAHT, legends placed on
such certificates may include but shall not be limited to the following:

     "THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION
TO THE REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER THE EMPLOYEE STOCK
PURCHASE PLAN AS DEFINED IN SECTION 423 OF THE INTERNAL REVENUE CODE OF 1986, AS
AMENDED, THE TRANSFER AGENT FOR THE SHARES EVIDENCED HEREBY SHALL NOTIFY THE
CORPORATION IMMEDIATELY OF ANY TRANSFER OF THE SHARES BY THE REGISTERED HOLDER
HEREOF MADE ON OR BEFORE ______________.  THE REGISTERED HOLDER SHALL

                                       9
<PAGE>

HOLD ALL SHARES PURCHASED UNDER THE PLAN IN THE REGISTERED HOLDER'S NAME (AND
NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE."

     20.  Notification of Sale of Shares.  HAHT may require the Participant to
          ------------------------------
give HAHT prompt notice of any disposition of Shares acquired by exercise of a
Purchase Right within two years from the date of granting such Purchase Right
(i.e., the Offering Date of the Offering Period containing the Purchase Date on
which such Shares were acquired).  HAHT may require that until such time as a
Participant disposes of Shares acquired upon exercise of a Purchase Right, the
Participant shall hold all such Shares in the Participant's name (and not in the
name of any nominee) until the lapse of the time periods with respect to such
Purchase Right referred to in the preceding sentence.  HAHT may direct that the
certificates evidencing Shares acquired by exercise of a Purchase Right refer to
such requirement to give prompt notice of disposition.

     21.  Amendment or Termination of the Plan.  The Board may at any time amend
          ------------------------------------
or terminate the Plan, except that such termination shall not affect Purchase
Rights previously granted under the Plan, nor may any amendment make any change
in a Purchase Right previously granted under the Plan which would adversely
affect the right of any Participant (except to the extent permitted by the Plan
or as may be necessary to qualify the Plan as an employee stock purchase plan
pursuant to section 423 of the Code or to obtain qualification or registration
of the Shares under applicable foreign, federal or state securities laws).  In
addition, an amendment to the Plan must be approved by the stockholders of the
Company within twelve (12) months of the adoption of such amendment if such
amendment would change the number of Shares authorized for issuance under the
Plan or would change the definition of the employees (or class of employees)
eligible to participate in the Plan, including the corporations that may be
designated by the Board as Participating Companies.  Furthermore, the approval
of the Company's stockholders shall be sought for any amendment to the Plan for
which the Board deems stockholder approval necessary in order to comply with
Rule 16b-3 promulgated under section 16 of the Securities Exchange Act of 1934.

     The foregoing HAHT Commerce, Inc. 2000 Employee Stock Purchase Plan was
duly adopted by the Board of Directors of HAHT on the ___ day of __________ 2000
and was approved by the stockholders on the ___ day of ___________ 2000.
