      Upon Employee's resignation or termination under this Paragraph 8 for any
reason, August Technology shall pay Employee his/her Base Salary through the
Employee's last date of employment, and any accrued and unused vacation or other
paid time off through the Employee's last date of employment. Employee's
entitlement to any vested pension, profit sharing or other benefits shall be
governed by applicable plan documents. In the event Employee's employment is
terminated either by Employee or August Technology under Paragraph 8 (b), August
Technology may elect, in its sole discretion, to pay Employee his/her salary for
the thirty (30) day notice period in lieu of Employee's continued performance of
duties during the notice period. In the event Employee is terminated by August
Technology in accordance with Paragraph 8 (b), August Technology shall, in
addition to the above, pay Employee a severance at his/her then current Base
Salary rate for the time period as set forth in Exhibit A as "Severance Period",
to be paid according to the normal payroll schedule, directly following the
thirty (30) day notice period, and August Technology shall, if the Employee
elects to continue group health or other group benefits as allowed by COBRA,
make the COBRA payments for the Severance Period. Employee shall not be entitled
to any further or other payments or benefits of any kind upon the Employee's
termination or resignation under this Paragraph 8. In the event, Employee is
entitled to Change in Control benefits as set forth in Paragraph 9, Employee
shall not be entitled to any severance or notice rights under this Paragraph 8.

      9. CHANGE IN CONTROL. If, within eighteen (18) months following a Change
in Control (as defined below), Employee's employment is terminated (as defined
below), then:

            (a)   Employee shall be paid his/her last Base Salary on a regular
                  payroll cycle as of the effective date for the time period as
                  set forth in Exhibit A as "Change In Control Severance Period"
                  from the effective date of such termination;

            (b)   For the same Change In Control Severance Period from the
                  effective date of such termination as set forth in Paragraph
                  9(b), the Company shall, if Employee elects to continue group
                  health or other group benefits as allowed under COBRA, make
                  the COBRA payments for the Change In Control Severance Period;

            (c)   The right to exercise all unexpired and non-vested stock
                  options in favor of Employee shall immediately vest and
                  accelerate; and

            (d)   LIMITATION ON CHANGE OF CONTROL PAYMENTS.  Employee shall not
                  be entitled to receive any Change of Control Action, as
                  defined below, which would constitute an "excess parachute
                  payment" for purposes of Code Section 280G, or any successor
                  provision, and the regulations thereunder.  In the event any
                  Change of Control Action payable to Employee would constitute
                  an "excess parachute payment," then the acceleration of the
                  exercisability of such stock options and the payments to such
                  Participant pursuant to this Paragraph 9 shall be reduced to
                  the largest extent or amount as will result in no portion of
                  such payments being subject to the excise tax imposed by
                  Section 4999 of the Code.  For purposes of this Paragraph 9,
                  a

                                       3

                  "Change of Control Action" shall mean any payment, benefit or
                  transfer of property in the nature of compensation paid to or
                  for the benefit of Employee under any arrangement which is
                  considered contingent on a Change of Control for purposes of
                  Code Section 280G, including, without limitation, any and all
                  salary, bonus, incentive, restricted stock, stock option,
                  compensation or benefit plans, programs or other arrangements,
                  and shall include benefits payable under this Agreement.

                        for the acquired business, or any combination of fully
                        closed and completed mergers, consolidations or
                        acquisitions during any consecutive twenty-four (24)
                        month period, if the individuals and entities who were
                        shareholders of the Company immediately prior to the
                        effective date of such merger, consolidation, or
                        acquisition (or prior to the effective date of the first
                        of a combination of such transactions) have, immediately
                        following the effective date of such merger,
                        consolidation or acquisition (or following the effective
                        date of the last of a combination of such transactions),
                        beneficial ownership (as defined in Rule 13d-3 under the

                  (2)   The acquisition of direct or indirect beneficial
                        ownership (as defined in Rule 13d-3 under the Securities

                        or entities acting in concert in one or a series of
                        transactions, which causes the aggregate beneficial

                        proposal for the liquidation of the Company; or

                        at any time during any consecutive twenty-four (24)
                        month period such that the "Continuity Directors" no
                        longer constitute at least a seventy percent (70%)
                        majority of the Board. For purposes of this event,
                        "Continuity Directors" means (i) those members of the
                        Board who were directors at the beginning of such
                        consecutive twenty-four (24) month period or at the date
                        of this Agreement if this Agreement was entered into

                        9(e)(4), or 9(e)(5) that ultimately results in such a
                        Change of Control, or a tender or exchange offer or
                        proxy contest is commenced that ultimately results in an

                        for any reason, with or without cause, except for
                        termination resulting from conduct by Employee
                        constituting (a) a felony involving moral turpitude
                        under either federal law or the law of the State of
                        Minnesota, or (b) Employee's willful failure to fulfill
                        his/her employment duties with the Company; provided,
                        however, that for purposes of this clause (c), an act or
                        failure to act by Employee shall not be "willful" unless
                        it is done, or omitted to be done, in bad faith and
                        without any reasonable belief that Employee's action or
                        omission were in the best interests of the Company; or

                  (2)   The termination of employment with the Company by
                        Employee for Good Reason. Such termination shall be

                        written notice to Company of his/her decision to
                        terminate. "Good Reason" shall mean a good faith
                        determination by Employee, in Employee's sole and
                        absolute judgment, that any one or more of the following
                        events has occurred, at any time during the term of this
                        Agreement or after a Change of Control; provided,
                        however, that such event shall not constitute "Good
                        Reason" if Employee has expressly consented to such
                        event in writing or if Employee fails to provide written
                        notice of his/her

<PAGE>
                        decision to terminate within sixty (60) days of the

                              removal of Employee from or any failure to
                              re-elect Employee to any of such positions, which
                              has the effect of materially diminishing
                              Employee's responsibility or authority;

                        (b)   A reduction by the Company in Employee's base
                              salary (as increased from time to time);

                        (c)   A requirement imposed by the Company on Employee
                              that results in Employee being based at a location
                              that is outside of a twenty-five (25) mile radius
                              of Employee's prior job location;

                        (d)   Without the adoption of a replacement plan,
                              program or arrangement that provides benefits to
                              Employee that are equal to or greater than those
                              benefits that are discontinued or adversely
                              affected:

                              i.    A failure by the Company to continue in
                                    effect, within its maximum stated term, any
                                    pension, bonus, incentive, stock ownership,
                                    stock purchase, stock option, life
                                    insurance, health, accident, disability, or
                                    any other employee compensation or benefit
                                    plan, program or arrangement, in which
                                    Employee is or has been participating;

                              ii.   The taking of any action by the Company
                                    that would adversely affect Employee's
                                    participation or materially reduce
                                    Employee's benefits under any of such
                                    plans, programs or arrangements; or

                        (e)   Any action by the Company that would materially
                              adversely affect the physical conditions in or
                              under which Employee performs his/her employment
                              duties; or

                        (f)   Any material breach by the Company of this
                              Employment Agreement between Employee and the
                              Company.

                        Termination for "Good Reason" shall not include

                  those provided or sold by August Technology or any
                  subsidiary, or clearly contemplated thereby due to research,
                  development, engineering, applications, licensing, or other

all of the benefits, profits, results and work product arising from or incident
to all work, services, advice and activities of Employee, including without

name creations, and copyrightable materials. Employee shall not, during the term
of his/her employment by August Technology, be interested, directly or
indirectly, in any manner, including, but not limited to, as partner, officer,
advisor, or in any other capacity in any other business similar to, or in

      Employee agrees to communicate promptly and fully to August Technology all
inventions, discoveries, improvements or designs conceived or reduced to
practice by Employee during the period of his/her employment with August
Technology (alone or jointly with others), and, except as provided in this
Paragraph 12, Employee will and hereby does assign to August Technology and/or
its nominees all of the Employee's right, title and interest in such inventions,
discoveries, improvements or designs and all of his/her right, title and
interest in any patents, patent applications or copyrights based thereon without
obligation on the part of August Technology or any subsidiary to make any
further compensation, royalty or payment to Employee. Employee further agrees to
assist August Technology and/or its nominee (without charge but at no expense to
Employee) at any time and in every proper way to obtain and maintain for its
and/or their own benefit, patents for all such inventions, discoveries and
improvements and copyrights for all such designs.

      This Agreement does not obligate Employee to assign to August Technology
any invention, discovery, improvement or design for which no equipment,
supplies, facility or trade secret information of August Technology or any
subsidiary was used and which was developed entirely on Employee's own time, and
(1) which does not relate (a) directly to the business of August Technology or
any subsidiary, or (b) to August Technology's or any subsidiary's actual or
demonstrably anticipated research or development, or (2) which does not result
from any work performed by Employee for August Technology or any subsidiary.

      13. EXEMPT INVENTIONS. Identified under Exempt Inventions in Exhibit A by
descriptive title are all of the Inventions, if any, in which Employee possesses
any right, title or interest prior to Employee's employment with August
Technology or execution of this Employment Agreement which are not subject to
the terms hereof.

      14. COPYRIGHTS. Employee acknowledges that any documents, drawings,
computer software or other work of authorship prepared by Employee within the
scope of his/her employment is a "work made for hire" under U.S. copyright laws
and that, accordingly, August Technology exclusively owns all copyright rights
in such works of authorship. For purposes of this paragraph, "scope of
employment" means that the work of authorship (a) relates to any subject matter
pertaining to his/her employment, (b) relates to or is directly or indirectly
connected with the existing or reasonably foreseeable business, products,
projects or confidential information of August Technology or any subsidiary, or
(c) involves the use of any time, material or facility of August Technology or

August Technology or any subsidiary or in any way related to the business of
August Technology or any subsidiary or the services Employee performed for
August Technology or any subsidiary, including but not limited to any documents
or items containing trade secret, proprietary, or confidential information,
documents in any way relating to any inventions or copyrights, client or
customer information, information relating to August Technology's or any
subsidiary's processes or procedures and any other materials or documents of any
sort relating to August Technology or any subsidiary. Employee shall not retain
any copies or summaries of any kind of documents and materials covered by this

      16. REMEDY UPON VIOLATION. Employee and August Technology agree that a
breach or threatened breach of Paragraphs 10, 11, 12, 14 or 15 would cause
irreparable harm to August Technology and/or its subsidiaries, and that monetary
damages alone would not be an adequate remedy. Employee agrees that August
Technology and any subsidiary shall be entitled, in addition to any other remedy
it may have at law or in equity, to an injunction, without the posting of a bond
if allowed by applicable law or with the posting of a minimal bond if required,
enjoining or restraining Employee from any violation or violations or threatened
violation or violations of Paragraphs 10, 11, 12, 14 and 15, and/or for specific
performance of duties and obligations under such paragraphs, and Employee hereby
consents to the issuance of such injunction. If any rights or restrictions
contained in Paragraphs 10, 11, 12, 14 and 15 shall be deemed to be
unenforceable by reason of the extent, duration or geographic scope, or other
provision thereof, the parties contemplate that the Court shall reduce such
extent, duration or geographic scope or other provision and enforce Paragraphs
10, 11, 12, 14 and 15 in their reduced form for all purposes in the manner
contemplated by such Paragraphs.

      17. OTHER AGREEMENTS. By Employee's signature to this Agreement, Employee
warrants that he/she is not subject to any employment, noncompetition,
confidentiality, inventions or other obligations or agreements which would
prevent or restrict the Employee in any way from accepting employment with
August Technology and fully performing his/her duties and responsibilities as
described in this Agreement. Employee, by his/her signature to this Agreement,
further warrants that he/she has not taken and will not take any trade secret,
proprietary or confidential information of any former employer, and will not use
or disclose any such information to anyone in the performance of duties and
responsibilities under this Agreement.

                                       2
<PAGE>
      Upon Employee's resignation or termination under this Paragraph 8 for any
reason, August Technology shall pay Employee his/her Base Salary through the
Employee's last date of employment, and any accrued and unused vacation or other
paid time off through the Employee's last date of employment. Employee's
entitlement to any vested pension, profit sharing or other benefits shall be
governed by applicable plan documents. In the event Employee's employment is
terminated either by Employee or August Technology under Paragraph 8 (b), August
Technology may elect, in its sole discretion, to pay Employee his/her salary for
the thirty (30) day notice period in lieu of Employee's continued performance of
duties during the notice period. In the event Employee is terminated by August
Technology in accordance with Paragraph 8 (b), August Technology shall, in
addition to the above, pay Employee a severance at his/her then current Base
Salary rate for the time period as set forth in Exhibit A as "Severance Period",
to be paid according to the normal payroll schedule, directly following the
thirty (30) day notice period, and August Technology shall, if the Employee
elects to continue group health or other group benefits as allowed by COBRA,
make the COBRA payments for the Severance Period. Employee shall not be entitled
to any further or other payments or benefits of any kind upon the Employee's
termination or resignation under this Paragraph 8. In the event, Employee is
entitled to Change in Control benefits as set forth in Paragraph 9, Employee
shall not be entitled to any severance or notice rights under this Paragraph 8.

      9. CHANGE IN CONTROL. If, within eighteen (18) months following a Change
in Control (as defined below), Employee's employment is terminated (as defined
below), then:

            (a)   Employee shall be paid his/her last Base Salary on a regular
                  payroll cycle as of the effective date for the time period as
                  set forth in Exhibit A as "Change In Control Severance Period"
                  from the effective date of such termination;

            (b)   For the same Change In Control Severance Period from the
                  effective date of such termination as set forth in Paragraph
                  9(b), the Company shall, if Employee elects to continue group
                  health or other group benefits as allowed under COBRA, make
                  the COBRA payments for the Change In Control Severance Period;

            (c)   The right to exercise all unexpired and non-vested stock
                  options in favor of Employee shall immediately vest and
                  accelerate; and

            (d)   LIMITATION ON CHANGE OF CONTROL PAYMENTS. Employee shall not
                  be entitled to receive any Change of Control Action, as
                  defined below, which would constitute an "excess parachute
                  payment" for purposes of Code Section 280G, or any successor
                  provision, and the regulations thereunder. In the event any
                  Change of Control Action payable to Employee would constitute
                  an "excess parachute payment," then the acceleration of the
                  exercisability of such stock options and the payments to such
                  Participant pursuant to this Paragraph 9 shall be reduced to
                  the largest extent or amount as will result in no portion of
                  such payments being subject to the excise tax imposed by
                  Section 4999 of the Code. For purposes of this Paragraph 9, a
                  "Change of Control Action" shall mean any payment, benefit or
                  transfer of property in the nature of compensation paid to or
                  for the benefit of Employee

                                       3
<PAGE>
                  under any arrangement which is considered contingent on a
                  Change of Control for purposes of Code Section 280G,
                  including, without limitation, any and all salary, bonus,
                  incentive, restricted stock, stock option, compensation or
                  benefit plans, programs or other arrangements, and shall
                  include benefits payable under this Agreement.

            (e)   "CHANGE OF CONTROL." For purposes of this Agreement, "Change
                  of Control" shall mean any of the following events occurring
                  after the date of this Agreement:

                  (1)   A merger or consolidation to which the Company is a
                        party, an acquisition by the Company involving the
                        issuance of the Company's securities as consideration
                        for the acquired business, or any combination of fully
                        closed and completed mergers, consolidations or
                        acquisitions during any consecutive twenty-four (24)
                        month period, if the individuals and entities who were
                        shareholders of the Company immediately prior to the
                        effective date of such merger, consolidation, or
                        acquisition (or prior to the effective date of the first

                        longer constitute at least a seventy percent (70%)
                        majority of the Board. For purposes of this event,

                        in principle or a definitive agreement relating to an
                        event described in Paragraph 9(e)(1), 9(e)(2), 9(e)(3),
                        9(e)(4), or 9(e)(5) that ultimately results in such a
                        Change of Control, or a tender or exchange offer or
                        proxy contest is commenced that ultimately results in an

                  (1)   The termination of Employee's employment by the Company
                        for any reason, with or without cause, except for
                        termination resulting from conduct by Employee
                        constituting (a) a felony involving moral turpitude
                        under either federal law or the law of the State of
                        Minnesota, or (b) Employee's willful failure to fulfill
                        his/her employment duties with the Company; provided,
                        however, that for purposes of this clause (c), an act or
                        failure to act by Employee shall not be "willful" unless
                        it is done, or omitted to be done, in bad faith and
                        without any reasonable belief that Employee's action or
                        omission were in the best interests of the Company; or

                  (2)   The termination of employment with the Company by
                        Employee for Good Reason. Such termination shall be

                        written notice to Company of his/her decision to
                        terminate. "Good Reason" shall mean a good faith
                        determination by Employee, in Employee's sole and
                        absolute judgment, that any one or more of the following
                        events has occurred, at any time during the term of this
                        Agreement or after a Change of Control; provided,
                        however, that such event shall not constitute "Good
                        Reason" if Employee has expressly consented to such
                        event in writing or if Employee fails to provide written
                        notice of his/her decision to terminate within sixty
                        (60) days of the occurrence of such event:

                        (a)   A material change in Employee's reporting
                              responsibilities, titles or offices, or any
                              removal of Employee from or any failure to
                              re-elect Employee to any of such positions, which

                                       5
<PAGE>
                              has the effect of materially diminishing
                              Employee's responsibility or authority;

                        (b)   A reduction by the Company in Employee's base
                              salary (as increased from time to time);

                        (c)   A requirement imposed by the Company on Employee
                              that results in Employee being based at a location
                              that is outside of a twenty-five (25) mile radius
                              of Employee's prior job location;

                        (d)   Without the adoption of a replacement plan,
                              program or arrangement that provides benefits to
                              Employee that are equal to or greater than those
                              benefits that are discontinued or adversely
                              affected:

                              i.    A failure by the Company to continue in
                                    effect, within its maximum stated term, any
                                    pension, bonus, incentive, stock ownership,
                                    stock purchase, stock option, life
                                    insurance, health, accident, disability, or
                                    any other employee compensation or benefit
                                    plan, program or arrangement, in which
                                    Employee is or has been participating;

                              ii.   The taking of any action by the Company
                                    that would adversely affect Employee's
                                    participation or materially reduce
                                    Employee's benefits under any of such
                                    plans, programs or arrangements; or

                        (e)   Any action by the Company that would materially
                              adversely affect the physical conditions in or
                              under which Employee performs his/her employment
                              duties; or

                        (f)   Any material breach by the Company of this
                              Employment Agreement between Employee and the
                              Company.

                        Termination for "Good Reason" shall not include
                  Employee's death or a termination for any reason other than
                  the events specified in clauses (a) through (f) above.

      10. CONFIDENTIAL INFORMATION. During the term of this Agreement and at all
times thereafter, Employee shall not directly or indirectly use or disclose any
trade secret, proprietary or confidential information of August Technology or
any subsidiary for the benefit of any person or entity other than August
Technology or any subsidiary without prior written approval of August
Technology's Board of Directors. For purposes of this Agreement, in addition to
all materials and information protected by applicable statute or law, the
parties acknowledge that confidential information shall include any information,
whether in print, on computer disc or tape or otherwise,

                                       6

Technology or any subsidiary, and information relating to August Technology's or
any subsidiary's methods of operation.

      11. NONCOMPETITION OBLIGATIONS. As a condition to and in consideration of
his/her employment and continued employment, and in exchange for the severance
and Change of Control provisions as set forth in Paragraphs 8 and 9 of this
Employment Agreement, and the mutual covenants herein, Employee agrees that,
during his/her employment and for a period of one (1) year following his/her
voluntary or involuntary resignation or termination for any reason, the Employee
will not, on behalf of himself/herself or any other person or entity:

            (a)   Directly or indirectly solicit, on Employee's own behalf, or
                  on behalf of another, any of August Technology's or any
                  subsidiary's customers or potential customers with whom
                  Employee or Employee's supervisees had contact, either
                  directly or indirectly, within the twelve months immediately
                  preceding Employee's resignation or termination of
                  employment, for the purpose of providing, selling, or
                  attempting to sell any products or services competing with
                  those provided or sold by August Technology or any
                  subsidiary, or clearly contemplated thereby due to research,
                  development, engineering, applications, licensing, or other
                  like projects in process, at the time of resignation or
                  termination; or

            (b)   hire or attempt to hire, or influence or solicit, or attempt
                  to influence or solicit, either directly or indirectly, any
                  employee of August Technology or any subsidiary to leave or
                  terminate his/her or her employment, or to work for any other
                  person or entity.

      12. WORK PRODUCT AND INVENTIONS. August Technology shall be entitled to
all of the benefits, profits, results and work product arising from or incident
to all work, services, advice and activities of Employee, including without
limitation all rights in inventions (as set forth below), trademark or trade
name creations, and copyrightable materials. Employee shall not, during the term
of his/her employment by August Technology, be interested, directly or
indirectly, in any manner, including, but not limited to, as partner, officer,
advisor, or in any other capacity in any other business similar to, or in
competition with, August Technology's or any subsidiary's business.

      Employee agrees to communicate promptly and fully to August Technology all
inventions, discoveries, improvements or designs conceived or reduced to
practice by Employee during the period of his/her employment with August
Technology (alone or jointly with others), and, except as provided in this
Paragraph 12, Employee will and hereby does assign to August Technology and/or
its nominees all of the Employee's right, title and interest in such inventions,
discoveries, improvements or designs and all of his/her right, title and
interest in any patents, patent applications

                                       7
<PAGE>
or copyrights based thereon without obligation on the part of August Technology
or any subsidiary to make any further compensation, royalty or payment to
Employee. Employee further agrees to assist August Technology and/or its nominee
(without charge but at no expense to Employee) at any time and in every proper
way to obtain and maintain for its and/or their own benefit, patents for all
such inventions, discoveries and improvements and copyrights for all such
designs.

      This Agreement does not obligate Employee to assign to August Technology
any invention, discovery, improvement or design for which no equipment,
supplies, facility or trade secret information of August Technology or any
subsidiary was used and which was developed entirely on Employee's own time, and
(1) which does not relate (a) directly to the business of August Technology or
any subsidiary, or (b) to August Technology's or any subsidiary's actual or
demonstrably anticipated research or development, or (2) which does not result
from any work performed by Employee for August Technology or any subsidiary.

      13. EXEMPT INVENTIONS. Identified under Exempt Inventions in Exhibit A by
descriptive title are all of the Inventions, if any, in which Employee possesses
any right, title or interest prior to Employee's employment with August
Technology or execution of this Employment Agreement which are not subject to
the terms hereof.

      14. COPYRIGHTS. Employee acknowledges that any documents, drawings,
computer software or other work of authorship prepared by Employee within the
scope of his/her employment is a "work made for hire" under U.S. copyright laws
and that, accordingly, August Technology exclusively owns all copyright rights
in such works of authorship. For purposes of this paragraph, "scope of
employment" means that the work of authorship (a) relates to any subject matter
pertaining to his/her employment, (b) relates to or is directly or indirectly
connected with the existing or reasonably foreseeable business, products,
projects or confidential information of August Technology or any subsidiary, or
(c) involves the use of any time, material or facility of August Technology or
any subsidiary.

      15. RETURN OF PROPERTY. Employee shall, immediately upon his/her
involuntary or voluntary resignation or termination from employment for any
reason, deliver to August Technology all documents and other items, whether on
computer disc or tape or otherwise, including all copies thereof, belonging to
August Technology or any subsidiary or in any way related to the business of
August Technology or any subsidiary or the services Employee performed for
August Technology or any subsidiary, including but not limited to any documents
or items containing trade secret, proprietary, or confidential information,
documents in any way relating to any inventions or copyrights, client or
customer information, information relating to August Technology's or any
subsidiary's processes or procedures and any other materials or documents of any
sort relating to August Technology or any subsidiary. Employee shall not retain
any copies or summaries of any kind of documents and materials covered by this
Paragraph 15.

      16. REMEDY UPON VIOLATION. Employee and August Technology agree that a
breach or threatened breach of Paragraphs 10, 11, 12, 14 or 15 would cause
irreparable harm to August Technology and/or its subsidiaries, and that monetary
damages alone would not be an adequate remedy. Employee agrees that August
Technology and any subsidiary shall be entitled, in addition to any other remedy
it may have at law or in equity, to an injunction, without the posting of a bond
if allowed by applicable law or with the posting of a minimal bond if required,
enjoining or

                                       8
<PAGE>
restraining Employee from any violation or violations or threatened violation or
violations of Paragraphs 10, 11, 12, 14 and 15, and/or for specific performance
of duties and obligations under such paragraphs, and Employee hereby consents to
the issuance of such injunction. If any rights or restrictions contained in
Paragraphs 10, 11, 12, 14 and 15 shall be deemed to be unenforceable by reason
of the extent, duration or geographic scope, or other provision thereof, the
parties contemplate that the Court shall reduce such extent, duration or
geographic scope or other provision and enforce Paragraphs 10, 11, 12, 14 and 15
in their reduced form for all purposes in the manner contemplated by such
Paragraphs.

      17. OTHER AGREEMENTS. By Employee's signature to this Agreement, Employee
warrants that he/she is not subject to any employment, noncompetition,
confidentiality, inventions or other obligations or agreements which would
prevent or restrict the Employee in any way from accepting employment with
August Technology and fully performing his/her duties and responsibilities as
described in this Agreement. Employee, by his/her signature to this Agreement,
further warrants that he/she has not taken and will not take any trade secret,
proprietary or confidential information of any former employer, and will not use
or disclose any such information to anyone in the performance of duties and
responsibilities under this Agreement.

      18. SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit of
and be binding upon the successors and assigns of August Technology.

      19. NOTICES. All notices and other communications to be given under this
Agreement shall be in writing and shall be deemed to be given when delivered
personally, or when mailed by registered or certified mail, addressed to the

sooner.

      20. SURVIVAL OF PROVISIONS. Employee acknowledges and agrees that the
restrictions and obligations set forth in Paragraphs 10, 11, 12, 13, 14, 15 and
16 of this Agreement are

                                       9
<PAGE>
reasonable, shall survive his/her resignation from or the termination of his/her
employment, and shall apply to him/her whether his/her resignation or
termination from employment is voluntary or involuntary and regardless of the
reason for such resignation or termination.

      21. NONWAIVERS. No failure on the part of either party to exercise, and no
delay in exercising, any right or remedy hereunder shall operate as a waiver

hereunder preclude any other or further exercise thereof or the exercise of any
right or remedy granted hereby or by any related document or by law.

counterparts, each of which shall be deemed an original, but all of which shall
constitute one (1) and the same instrument.

      25. ENTIRE AGREEMENT. This Agreement states the entire Agreement of the
parties on the subjects set forth herein, and merges and supersedes all prior
agreements and understandings between the parties. No modification, termination,
or attempted waiver of any provision of this Agreement will be valid unless it
is made in writing and signed by the party against whom the same is sought to be
enforced, and is specifically identified as a modification, termination,
release, waiver or discharge of this Agreement. If any term, clause or provision
of this Agreement shall for any reason be adjudged invalid, unenforceable or
void, the same shall not impair or invalidate any of the other provisions
contained herein, all of which shall be performed in accordance with their
respective terms.
