         3.       ELIGIBILITY.

                  (a) General Rule. Any Employee on an Enrollment Date shall be

         Period beginning on such Enrollment Date, subject to the requirements

         notwithstanding, no Employee shall be an Eligible Employee if:

                           (i) Immediately after the grant, such Employee (or
                  any other person whose stock would be attributed to such
                  Employee pursuant to section 424(d) of the Code) would own

   3

                  the Code; or

                           (ii) Such option would permit such Employee's right
                  to purchase stock under all employee stock purchase plans
                  (described in section 423 of the Code) of the Company and its
                  Subsidiaries to accrue at a rate which exceeds $25,000 of the

                  option is outstanding at any time, in accordance with the
                  provisions of section 423(b)(8) of the Code.

         4.       PARTICIPATION.

                  (a) An Eligible Employee may become a Participant in the Plan
         by completing a Subscription Agreement authorizing payroll deductions,
         in a form substantially similar to EXHIBIT A attached to this Plan
         ("Subscription Agreement"), and filing it with the Company's Human
         Resources Department prior to the applicable Enrollment Date, unless a
         later time for filing the Subscription Agreement is set by the
         Committee for all Eligible Employees with respect to a given Offering
         Period.

                  (b) Payroll deductions for a Participant shall commence with
         the first payroll following the Enrollment Date and shall end on the
         last payroll in the Offering Period to which such authorization is
         applicable, unless sooner terminated by the Participant as provided in
         PARAGRAPH 9.

                  (c) An Eligible Employee may waive his right to participate
         for any Offering Period by declining to authorize a payroll deduction.
         Such declination must be filed in writing in the time and manner
         specified thereby. The filing of a written declination shall result in
         the Employee's waiver of participation for only the Offering Period to
         which it relates and shall be irrevocable with respect to such
         Offering Period. Except as otherwise provided in this Paragraph, an
         Employee's waiver of participation for a specified Offering Period
         shall not, in and of itself, adversely impact the right of such
         Employee to participate in the Plan during any subsequent Offering
         Periods except those Offering Periods with respect to which he files
         additional written declinations in accordance with the provisions of
         this Paragraph.

         5.       PAYROLL DEDUCTIONS.

                  (a) At the time a Participant files his or her Subscription
         Agreement, such Participant shall elect to have payroll deductions (in
         whole percentage increments) made on each pay date during the Offering
         Period in an amount of not less than 1% nor more than 15% of the
         Compensation which he or she receives on each pay date during the
         Offering Period.

                  (b) All payroll deductions made by a Participant shall be
         credited to his or her Payroll Deduction Account under the Plan. No
         interest shall accrue on the payroll deductions in a Participant's
         Payroll Deduction Account in the Plan.

                  (c) No changes in the rate of payroll deductions other than a
         withdrawal pursuant to PARAGRAPH 9 are permitted.

         6.       GRANT OF OPTION.

                  (a) On the Enrollment Date of each Offering Period during the
         term of the Plan each Participant in such Offering Period shall be
         granted an option to purchase up to a number of whole Shares
         determined by dividing 15% of the Participant's Compensation by the
         Exercise Price; provided, however, that the number of shares


   4

         subject to such option shall be reduced, if necessary, to a number of
         shares which would not exceed the limitations described in PARAGRAPH
         3(b) or PARAGRAPH 10(a) hereof. The fair market value of a Share shall
         be determined as provided in PARAGRAPH 6(b).

                  (b) The "Exercise Price" per Share offered in a given
         Offering Period shall be determined by the Committee but shall not be
         less than the lower of: (i) 85% of the fair market value of a Share on
         the Enrollment Date, or (ii) 85% of the fair market value of a Share
         on the Exercise Date. The fair market value of a Share on a given date
         shall be the closing price of such Share as reported by the Nasdaq
         National Market or reported on such other national exchange as it may,
         from time to time, be reported on, on such date (or if there shall be
         no trading on such date, then on the first previous date on which
         there is such trading), unless the Shares cease to be traded on a
         national exchange. If the Shares cease to be traded on a national
         exchange, fair market value shall be determined by the Committee in
         its discretion consistent with section 423 of the Code or the
         regulations thereunder.

                  (c) All grants made hereunder shall be deemed to have been
         made on the applicable Enrollment Date.

         7.       EXERCISE OF OPTION. The Participant's option for the
purchase of Shares will be exercised automatically on the Exercise Date of each
Offering Period, and the maximum number of full shares subject to such option
will be purchased for such Participant at the applicable Exercise Price with
the payroll deductions accumulated in his or her Payroll Deduction Account,
unless prior to such Exercise Date the Participant has withdrawn from the
Offering Period as provided in PARAGRAPH 9. During a Participant's lifetime a
Participant's option to purchase shares hereunder is exercisable only by such
Participant. Any amount remaining in the Participant's Payroll Deduction
Account after the Offering Period shall be held in the Payroll Deduction
Account until the next Offering Period, unless the Offering Period has been
oversubscribed or has terminated, in which case such amount shall be refunded
to the Participant.

         8.       DELIVERY. As soon as practicable after the Exercise Date, the
Committee shall arrange the delivery to each Participant, or to his account at
a brokerage firm, of a certificate representing the shares purchased upon
exercise of his or her option.

         9.       WITHDRAWAL; TERMINATION OF EMPLOYMENT.

                  (a) A Participant may withdraw all, but not less than all, of
         the payroll deductions credited to his or her Payroll Deduction
         Account and not yet used toward the exercise of his or her option
         under the Plan at any time by giving written notice to the Committee
         on a form substantially similar to EXHIBIT B attached to this Plan.
         All of the Participant's payroll deductions credited to his or her
         Payroll Deduction Account that have not yet been used to purchase
         Shares will be paid to such Participant as soon as practicable after
         receipt of his or her notice of withdrawal. A withdrawal of a
         Participant's Payroll Deduction Account shall terminate the
         Participant's participation for the Offering Period in which the
         withdrawal occurs. No further payroll deductions for the purchase of
         shares will be made during the Offering Period.

                  (b) Upon termination of the Participant's Continuous Status
         as an Employee of the Company for any reason, he or she will be deemed
         to have elected to withdraw from the Plan and the payroll deductions
         credited to his or her Payroll Deduction Account will be returned to
         such Participant and his or her option will be canceled; provided,
         however, a Participant who goes on a leave of absence shall be
         permitted to remain in the Plan with respect to an Offering Period
         which commenced prior to the


   5

         beginning of such leave of absence. If such Participant is not
         guaranteed reemployment by contract or statute and the leave of
         absence exceeds 90 days, such Participant shall be deemed to have
         terminated employment on the 91st day of such leave of absence.
         Payroll deductions for a Participant who has been on a leave of
         absence will resume upon return to work at the same rate as in effect
         prior to such leave unless the leave of absence begins in one Offering
         Period and ends in a subsequent Offering Period, in which case the
         Participant shall not be permitted to re-enter the Plan until a new
         Subscription Agreement is filed with respect to an Offering Period
         which commences after such Participant has returned to work from the
         leave of absence.

                  (c) A Participant's withdrawal from one Offering Period will
         not have any effect upon his or her eligibility to participate in a
         different Offering Period or in any similar plan which may hereafter
         be adopted by the Company.

         10.      SHARES.

                  (a) The maximum number of Shares which shall be made
         available for sale under the Plan shall be 200,000 Shares, subject to
         adjustment upon changes in capitalization of the Company as provided
         in PARAGRAPH 16. Either authorized and unissued Shares or issued
         Shares heretofore or hereafter reacquired by the Employer may be made
         subject to purchase under the Plan, in the sole and absolute
         discretion of the Committee. Further, if for any reason any purchase
         of any Shares under the Plan is not consummated, Shares subject to
         such purchase agreement may be subjected to a new Subscription
         Agreement under the Plan. If, on the Exercise Date, the number of
         Shares with respect to which options are to be exercised exceeds the
         number of Shares then available under the Plan, the Company shall make
         a pro rata allocation of the shares remaining available for purchase
         in as uniform a manner as shall be practicable and as it shall
         determine to be equitable. In such event, the Company shall give
         written notice of such reduction of the Shares which each Employee
         shall be allowed to purchase. Notwithstanding anything to the contrary
         herein, the Company shall not be obligated to issue Shares hereunder
         if, in the opinion of counsel for the Company, such issuance would
         constitute a violation of federal or state securities laws.

                  (b) The Participant will have no interest or voting right in
         Shares covered by his or her option until such option has been
         exercised and the Shares have been issued or transferred to the
         Participant.

                  (c) Shares to be delivered to a Participant under the Plan
         will be registered in the name of the Participant or, at the prior
         written request of the Participant, in the names of the Participant
         and his or her spouse.

         11.      ADMINISTRATION. The Plan shall be administered by a Committee
appointed by the Board. Such Committee shall have all powers with respect to
the Plan, except for amending or terminating the Plan as set forth in PARAGRAPH
17 hereof.

                  (a) Each member of the Committee shall serve until his
         successor is appointed. Any member of the Committee may be removed at
         any time by the Board, with or without cause, which shall have the
         power to fill any vacancy which may occur. A Committee member may
         resign by giving 30 days written notice to the Company.

                  (b) The members of the Committee shall serve without
         compensation for services as such, but the Company shall pay all
         expenses of the Committee.

                  (c) The Committee shall have the following powers and duties:

   6

                           (1) To direct the administration of the Plan in
                  accordance with the provisions herein set forth;

                           (2) To adopt rules of procedure and regulations
                  necessary for the administration of the Plan provided the
                  rules are not inconsistent with the terms of the Plan;

                           (3) To determine all questions with regard to rights
                  of Employees and Participants under the Plan, including, but
                  not limited to, the eligibility of an Employee to participate
                  in the Plan;

                           (4) To enforce the terms of the Plan and the rules
                  and regulations it adopts;

                           (5) To direct the distribution of the Shares
                  purchased hereunder;

                           (6) To furnish the Employer with information which
                  the Employer may require for tax or other purposes;

                           (7) To engage the service of counsel (who may, if
                  appropriate, be counsel for an Employer) and agents whom it
                  may deem advisable to assist it with the performance of its
                  duties;

                           (8) To prescribe procedures to be followed by
                  Participants in electing to participate herein;

                           (9) To receive from each Employer and from Employees
                  such information as shall be necessary for the proper
                  administration of the Plan;

                           (10) To maintain, or cause to be maintained,
                  separate accounts in the name of each Participant to reflect
                  the Participant's Payroll Deduction Account under the Plan;
                  and

                           (11) To interpret and construe the Plan.

         12.      DESIGNATION OF BENEFICIARY.

                  (a) A Participant may file a written designation of a
         beneficiary (as indicated in the Subscription Agreement or otherwise)
         who is to receive any Shares under the Plan in the event of such
         Participant's death subsequent to the Exercise Date on which an option
         is exercised but prior to the issuance of such shares. In addition, a
         Participant may file a written designation of a beneficiary who is to
         receive any cash from the Participant's Payroll Deduction Account
         under the Plan in the event of such Participant's death prior to the
         Exercise Date of the option.

                  (b) Such designation of beneficiary may be changed by the
         Participant 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, the Committee 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 or Committee), the
         Committee, 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
         Committee, then to such other person as the Committee may designate.

   7

         13.      TRANSFERABILITY. Neither payroll deductions credited to
Participant's Payroll Deduction Account nor any rights with regard to the
exercise of an option 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 PARAGRAPH 12 hereof) by
the Participant. Any such attempt at assignment, transfer, pledge or other
disposition shall be without effect, except that the Committee may treat such
act as an election to withdraw funds in accordance with PARAGRAPH 9.

         14.      USE OF FUNDS. All payroll deductions 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 payroll deductions.

         15.      REPORTS. Individual Payroll Deduction Accounts will be
maintained for each Participant in the Plan. Statements of Payroll Deduction
Account will be given to Participants as soon as practicable following an
Exercise Date, such statements will set forth the amounts of payroll
deductions, the per share purchase price, the number of shares purchased and
the remaining cash balance, if any.

         16.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. If an option under
this Plan is exercised subsequent to any stock split, spinoff,
recapitalization, reorganization, reclassification, merger, consolidation,
exchange of shares, or the like occurring after such option was granted, as a
result of which shares of any class of stock shall be issued in respect of the
outstanding shares, or shares shall be changed into a different number of the
same or another class or classes, the number of Shares to which such option
shall be applicable and the option price for such Shares shall be appropriately
adjusted by the Company. Any such adjustment, however, in the Shares shall be
made without change in the total price applicable to the portion of the Shares
purchased hereunder which has not been fully paid for, but with a corresponding
adjustment, if appropriate, in the price for the Shares.

         In the event of the proposed dissolution or liquidation of the Company
or upon a proposed reorganization, merger, or consolidation of the Company with
one or more corporations as a result of which the Company is not the surviving
corporation, or upon a proposed sale of substantially all of the property or
stock of the Company to another corporation, the Offering Period will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board, and the holder of each option then outstanding under the
Plan will thereafter be entitled to receive, upon the exercise of such option,
as nearly as reasonably may be determined, the cash, securities, and/or
property which a holder of one Share was entitled to receive upon and at the
time of such transaction for each Share to which such option shall be
exercised. The Board shall take such steps in connection with such transactions
as the Board shall deem necessary to assure that the provisions of this
Paragraph shall thereafter be applicable, as nearly as reasonably may be
determined, in relation to the said cash, securities, and/or property as to
which such holder of such option might thereafter be entitled to receive.

         17.      AMENDMENT OR TERMINATION. The Board may at any time and for
any reason terminate or amend the Plan. Except as specifically provided in the
Plan, no such termination can affect options previously granted, provided that
an Offering Period may be terminated by the Board on any Exercise Date if the
Board determines that the termination of the Plan is in the best interest of
the Company and its stockholders. Except as specifically provided in the Plan
or as required to obtain a favorable ruling from the Internal Revenue Service
or to comply with tax or securities law, no amendment may make any change in
any option theretofore granted which adversely affects the rights of any
Participant. To the extent necessary to comply with Rule 16b-3 under the Act or
section 423 of the Code (or any successor rule or provision or any other
applicable law or regulation), the Company shall obtain stockholder approval in
such manner and to such a degree as required.

   8

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

         19.      STOCKHOLDER APPROVAL. Commencement of the Plan shall be
subject to approval by the stockholders of the Company within 12 months before
or after the date the Plan is adopted. Notwithstanding any provision to the
contrary, failure to obtain such stockholder approval shall void the Plan, any
options granted under the Plan, any Share purchases pursuant to the Plan, and
all rights of all Participants.

         20.      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 Act, the rules and regulations
promulgated thereunder, 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.

         21.      TERM OF PLAN. The Plan shall become effective upon the
earlier to occur of its adoption by the Board or its approval by the
stockholders of the Company as described in PARAGRAPH 19. It shall continue in
effect for a term of ten years unless sooner terminated under PARAGRAPH 17.

         22.      NO RIGHTS IMPLIED. Nothing contained in this Plan or any
modification or amendment to the Plan or in the creation of any Payroll
Deduction Account, or the execution of any participation election form, or the
issuance of any Shares, shall give any Employee or Participant any right to
continue employment, any legal or equitable right against the Employer or
Company or any officer, director, or Employee of an Employer or Company, except
as expressly provided by the Plan.

         23.      SEVERABILITY. In the event any provision of the Plan shall
be held to be illegal or invalid for any reason, the illegality or invalidity
shall not affect the remaining provisions of the Plan, but shall be fully
severable and the Plan shall be construed and enforced as if the illegal or
invalid provision had never been included herein.

         24.      WAIVER OF NOTICE. Any person entitled to notice under the
Plan may waive the notice.

         25.      SUCCESSORS AND ASSIGNS. The Plan shall be binding upon all
persons entitled to purchase Shares under the Plan, their respective heirs,
legatees, and legal representatives and upon the Employer, its successors and
assigns.

         26.      HEADINGS. The titles and headings of the Paragraphs are
included for convenience of reference only and are not to be considered in
construction of the provisions hereof.

   9

         27.      GOVERNING LAW. All questions arising with respect to the
provisions of this Plan shall be determined by application of the laws of the
State of Delaware except to the extent Delaware law is preempted by federal
statute. The obligation of the Employer to sell and deliver Shares under the
Plan is subject to applicable laws and to the approval of any governmental
authority required in connection with the authorization, issuance, sale or
delivery of such Shares.

         28.      NO LIABILITY FOR GOOD FAITH DETERMINATIONS. Neither the
members of the Board nor any member of the Committee (nor their delegates)
shall be liable for any act, omission, or determination taken or made in good
faith with respect to the Plan or any right to purchase Shares granted under
it, and members of the Board and the Committee (and their delegates) shall be
entitled to indemnification and reimbursement by the Company in respect of any
claim, loss, damage, or expense (including attorneys' fees, the costs of
settling any suit, provided such settlement is approved by independent legal
counsel selected by the Company, and amounts paid in satisfaction of a
judgment, except a judgment based on a finding of bad faith) arising therefrom
to the full extent permitted by law and under any directors and officers
liability or similar insurance coverage that may from time to time be in
effect.

         29.      PARTICIPATING EMPLOYERS. This Plan shall constitute the
employee stock purchase plan of the Company and each Designated Subsidiary. A
Designated Subsidiary may adopt and participate in this Plan beginning as of

Date.

                          EMPLOYEE STOCK PURCHASE PLAN
                             SUBSCRIPTION AGREEMENT

         I,_______________, have read the attached prospectus explanation of the
USDATA Corporation Employee Stock Purchase Plan (the "Plan"). I have decided
(check one):

                           NOT to participate.
                  -----
                           TO PARTICIPATE. I wish to purchase that number of
                  -----    shares of USDATA Corporation Common Stock, $.01 par
                           value (the "Shares"), that can be purchased with
                           ______% of my Compensation(1) (select the percentage
                           of your compensation from 1 to 15, in increments of
                           1, that you elect to contribute).

         In order to pay for the Shares that I have elected to purchase, I
hereby authorize my Employer to deduct the percentage of my Compensation that I
specified above from my pay each pay period while this election is in effect.

         I understand that said payroll deductions shall be accumulated for the
purchase of the 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 the
Exercise Date of the Offering Period unless I otherwise withdraw from the
Offering Period or the Plan.

         I have received a copy of USDATA Corporation's most recent prospectus
that describes the Plan and a copy of the complete Plan. I understand that my
participation in the Plan is in all respects subject to the terms of the Plan.

         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.

         Beneficiary Designation. In the event of my death, I hereby designate
the following as my beneficiary to receive all payments and Shares due me and
not yet paid or issued under the Plan, pursuant to Paragraph 12 of the Plan:
