EXHIBIT 10.28

                    CHANGE OF CONTROL AND SEVERANCE AGREEMENT

     Agreement (hereinafter "Agreement") dated as of April 10, 2000 by and
between CFM Technologies, Inc., a Pennsylvania Business Corporation having a
place of business at 150 Oaklands Boulevard, Exton, PA 19341 ("CFM" or the
"Company"), and Roger A. Carolin, an individual residing at 158 Kentsdale Court,
Malvern, PA 19355 ("Carolin").

                                   WITNESSETH:

     WHEREAS, based upon Carolin's demonstrated commitment and unique
contributions to the Company, and a desire to motivate Carolin's retention prior
to the occurrence of a Change of Control Event (an "Event") as defined in
Section 5, herein, CFM desires that Carolin continue to be employed, prior to an
Event and, Carolin desires to be so employed, all pursuant to the terms and
conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the foregoing and the mutual promises
and covenants herein contained, and intending to be legally bound hereby, it is
agreed as follows:

1.    REPRESENTATIONS AND WARRANTIES BY CAROLIN AND CFM

     Carolin hereby represents and warrants to CFM as follows:

          (a) Neither the execution and delivery of this Agreement nor the
     performance by Carolin of his duties and other obligations hereunder
     violate or will violate any statute, law, determination or award, or
     conflict with or constitute a default under (whether immediately, upon the
     giving of notice or lapse of time or both) any prior employment agreement,
     contract, or other instrument to which Carolin is a party or by which he is
     bound.

          (b) Carolin has the right, power and legal capacity to enter and
     deliver this Agreement and to perform his duties and other obligations
     hereunder. This Agreement constitutes the legal, valid and binding
     obligation of Carolin enforceable against him in accordance with its terms.
     No approvals or consents of any persons or entities are required for
     Carolin to execute and deliver this Agreement or perform his duties and
     other obligations hereunder.

<PAGE>

     CFM hereby represents and warrants to Carolin as follows:

          (a) CFM is duly organized, validly existing and in good standing under
     the laws of the Commonwealth of Pennsylvania, with all requisite corporate
     power and authority to own its properties and conduct its business in the
     manner presently contemplated.

          (b) CFM has full power and authority to enter into this Agreement and
     to incur and perform its obligations hereunder.

          (c) The execution, delivery and performance by CFM of this Agreement
     does not conflict with or result in a breach or violation of or constitute
     a default under (whether immediately, upon the giving of notice or lapse of
     time or both) the certificate of incorporation or by-laws of CFM, or any
     agreement or instrument to which CFM is a party or by which CFM or any of
     its properties may be bound or affected.

2.   TERM

     This agreement shall terminate five (5) years from execution hereof or upon
the mutual agreement, in writing, of CFM and Carolin.

3.   EFFECTIVENESS

     This Agreement shall become effective only upon the assumption of control
by another entity ("Successors and Assigns") following an Event. This Agreement
shall have no force of effect until such an Event shall occur.

4.   TERMINATION OF EMPLOYMENT

     Carolin's employment hereunder shall continue until terminated upon the
first to occur of the following events:

          (a) THE DEATH OR DISABILITY OF CAROLIN. Successor and Assigns may, at
     its option, terminate Carolin's employment for "disability" (as hereinafter
     defined). In the event of termination for death or disability, Carolin or
     his designated beneficiary, shall be entitled to termination benefits
     pursuant to Section 5(d), which monthly benefits shall be reduced in each
     month such benefit may be received by any amounts received by Carolin from
     disability insurance during such month from a program provided by CFM or
     Successors and Assigns. For purposes of this Agreement, the term
     "disability" means any physical or mental illness, impairment or incapacity
     which prevents Carolin from performing, with or without accommodation, the
     essential functions of Carolin's position hereunder for a period totaling
     not less than one hundred eighty (180) days during any period of twelve
     (12) consecutive months.

                                       2
<PAGE>

          (b) TERMINATION BY THE PRESIDENT, CHAIRMAN OR BOARD OF DIRECTORS OF
     SUCCESSORS AND ASSIGNS FOR CAUSE. Any of the following actions by Carolin
     shall constitute cause:

               (i)  Material breach by Carolin of the provisions of the CFM
                    Non-Disclosure and Invention Agreement which he is a party
                    to (or any similar agreement entered into by Carolin with
                    Successors and Assigns) provided that Carolin has received
                    written notice of such breach from the President, Chairman
                    or Board of Directors of Successors and Assigns, and has had
                    an opportunity to respond to the notice in a meeting within
                    thirty (30) days of such notice; or

               (ii) Theft; a material act of dishonesty or fraud; intentional
                    falsification of any employment or Company records; or the
                    commission of any criminal act which impairs Carolin's
                    ability to perform appropriate employment duties under this
                    Agreement; or

              (iii) Carolin's conviction (including any plea of guilty or nolo
                    contendere) for a crime involving moral turpitude causing
                    material harm to the reputation and standing of Successors
                    and Assigns; or

               (iv) Gross negligence or willful misconduct in the performance of
                    Carolin's assigned duties; provided however, that merely
                    unsatisfactory performance by Carolin of such duties and
                    responsibilities shall not constitute "cause" for purposes
                    of the Agreement; and provided further that Carolin has
                    received written notice of such breach or neglect from the
                    President, Chairman or Board of Directors of Successors and
                    Assigns, has had an opportunity to respond to the notice in
                    a meeting and has failed to substantially cure such breach
                    or neglect within thirty (30) days of such notice.

          (c) TERMINATION BY CAROLIN FOR GOOD REASON. Any of the following
     actions or omissions by CFM or Successors and Assigns shall constitute good
     reason:

               (i)  Material breach by Successors and Assigns of any provision
                    of this Agreement which is not cured by Successors and
                    Assigns within fifteen (15) days of written notice thereof
                    from Carolin; or

               (ii) Any action by Successors and Assigns to intentionally harm
                    Carolin; or

              (iii) If, (i) upon the occurrence of an Event, Carolin's status,
                    title, position, and responsibilities are not expanded to
                    include responsibility for substantially all related
                    functional activities in the merger or combined
                    post-transition entity for which Carolin was responsible

3
<PAGE>

                    immediately prior to the Event, or (ii) at any time
                    thereafter, a change occurs in Carolin's status, title,
                    position, work location or compensation which, in either
                    event, in Carolin's reasonable judgment, represents a
                    material adverse change from his status, title, position,
                    work location, compensation, or responsibilities existing or
                    in effect prior to such change, Carolin may, at his sole
                    option by providing written notice deem such change to be
                    good reason under this Section 4(c).

               (iv) The failure of CFM to have obtained an agreement,
                    satisfactory to Carolin, from any successors and assigns to
                    assume and agree to perform this Agreement prior to the
                    occurrence of an Event.

     Carolin's right to terminate his employment pursuant to this Section 4(c)
shall not be affected by his incapacity due to disability.

     In the event of any action or omission constituting good reason (a "Good
Reason Event"), (1) any options to purchase common stock of CFM or Successors
and Assigns held by Carolin shall vest immediately as of the date of such
termination, (2) Successors and Assigns will pay to Carolin his target annual
bonus for the current fiscal year on a pro rata basis corresponding to the date
of termination, and (3) Carolin shall agree to serve as a consultant to
Successors and Assigns for up to twenty-six (26) days during the six (6) months
following termination hereunder at times and locations and with duties as
Carolin and Successors and Assigns may mutually agree, and (4) Successors and
Assigns will pay Carolin twenty-four (24) monthly payments equal to one twelfth
of Carolin's then current annual base salary plus annual target bonus and the
amount of $3,500 for each day of consulting in excess of twenty-six (26) days.

          (d) TERMINATION BY THE PRESIDENT, CHAIRMAN OR BOARD OF DIRECTORS OF
     SUCCESSORS AND ASSIGNS WITHOUT CAUSE.

               (i) Successors and Assigns shall give Carolin not less than
          thirty (30) days notice of the termination of Carolin's employment
          without cause and Successors and Assigns shall have the option of
          terminating Carolin's duties and responsibilities prior to the
          expiration of the notice period subject to payment by Successors and
          Assigns of Carolin's then current base pay for the remainder of the
          notice period; and

               (ii) Following any Termination of Carolin under 5(d)(i), above,
          (1) any options to purchase common stock of CFM or Successors and
          Assigns held by Carolin shall vest immediately as of the date of such
          termination, (2) Successors and Assigns will pay to Carolin his target
          annual bonus for the current fiscal year on a pro rata basis
          corresponding to the date of termination, and (3) Successors and
          Assigns will pay Carolin twenty-four (24) monthly payments equal to
          one twelfth of Carolin's then current annual base salary plus annual
          target bonus.

                                       4

<PAGE>

     (e) TERMINATION BY CAROLIN WITHOUT GOOD REASON.

     In the event Carolin wishes to resign, he shall give not less than thirty
(30) days prior notice of such resignation and Successors and Assigns shall have
the option of terminating Carolin's duties and responsibilities at any time
prior to Carolin's proposed termination date, subject to payment by Successors
and Assigns of the lesser of Carolin's then current base pay for a thirty (30)
day period, or such other period as may remain under the notice given by
Carolin.

5.   CHANGE OF CONTROL

     For purposes of this Agreement, a "Change of Control Event" shall mean any
of the following:

          (a) An acquisition (other than directly from CFM) of any voting
     securities of CFM (the "Voting Securities") by any "Person" (as the term
     person is used for purposes of Section 13(d) or 14(d) of the Securities
     Exchange Act of 1934, as amended (the "1934 Act") immediately after which
     such Person has "Beneficial Ownership" (within the meaning of Rule 13d-3
     promulgated under the 1934 Act) of thirty percent (30%) or more of the
     combined voting power of CFM's then outstanding Voting Securities;
     provided, however, that in determining whether a Change of Control Event
     has occurred, Voting Securities which are acquired in a "Non-Control
     Acquisition" (as defined below) shall not constitute an acquisition which
     would cause a Change of Control Event. A "Non-Control Acquisition" shall
     mean an acquisition by (1) an employee benefit plan (or trust forming a
     part thereof) maintained by (x) CFM or (y) any corporation or other Person
     of which a majority of its voting power or its equity securities or equity
     interest is owned directly or indirectly by CFM (a "Subsidiary"), (2) CFM
     or any Subsidiary, or (3) any Person in connection with a "Non-Control
     Transaction."

          (b) The individuals who, as of the date hereof, are members of the
     Board (the "Incumbent Board"), cease for any reason to constitute at least
     two-thirds of the Board; provided, however, that if the election, or
     nomination for election by CFM's stockholders, of any new director was
     approved by a vote of at least two-thirds of the then Incumbent Board, such
     new director shall, for purposes of this Agreement, be considered as a
     member of the Incumbent board; provided, further, that no individual shall
     be considered a member of the Incumbent Board if such individual initially
     assumed office as a result of either an actual or threatened "Election
     Contest" (as described in Rule 14a-11 promulgated under the 1934 Act) or
     other actual or threatened solicitation of proxies or consents by or on
     behalf of a Person other than the Board (a "Proxy Contest") including by
     reason of any agreement intended to avoid or settle any Election Contest or
     Proxy Contest; or

                                       5

<PAGE>

          (c) Approval by stockholders of CFM of:

               (i)  A merger, consolidation, or reorganization involving CFM,
                    unless

                    (1)  the stockholders of CFM, immediately before such
                         merger, consolidation or reorganization, own, directly
                         or indirectly, immediately following such merger,
                         consolidation or reorganization, at least seventy
                         percent (70%) of the combined voting power of the
                         outstanding Voting Securities of the corporation
                         resulting from such merger or consolidation or
                         reorganization (the "Surviving Corporation") in
                         substantially the same proportion as their ownership of
                         the Voting Securities immediately before such merger,
                         consolidation, or reorganization, and

                    (2)  the individuals who were members of the Incumbent Board
                         immediately prior to the execution of the agreement
                         providing for such merger, consolidation, or
                         reorganization constitute at least two-thirds of the
                         members of the board of directors of the Surviving
                         Corporation or corporation beneficially owning,
                         directly or indirectly, a majority of the Voting
                         Securities of the Surviving Corporation, and

                    (3)  no Person (other than CFM, any Subsidiary, any employee
                         benefit plan (or any trust forming a part thereof)
                         maintained by CFM, the Surviving Corporation or any
                         Subsidiary, or any Person who, immediately prior to
                         such merger, consolidation or reorganization had
                         Beneficial Ownership of fifteen percent (15%) or more
                         of the then outstanding Voting Securities) owns,
                         directly or indirectly, fifteen percent (15%) or more
                         of the combined voting power of the Surviving
                         Corporation's then outstanding voting securities, and

                    (4)  a transaction described in clauses 1 through 3 shall
                         herein be referred to as a "Non-Control Transaction";

               (ii) A complete liquidation or dissolution of CFM, or

               (iii) A sale or other disposition of all or substantially all of
                    the assets of CFM to any Person (other than a transfer to a
                    Subsidiary).

                                       6

<PAGE>

          (d) Notwithstanding the foregoing, a Change of Control Event shall not
     be deemed to occur solely because any Person (the "Subject Person")
     acquired Beneficial Ownership of more than the permitted amount of the
     outstanding Voting Securities as a result of the acquisition of Voting
     Securities by CFM which by reducing the number of Voting Securities
     outstanding, increases the proportional number of shares Beneficially Owned
     by the Subject Person, provided that if a Change in Control would occur
     (but for the operation of this sentence) as a result of the acquisition of
     Voting Securities by CFM, and after such share acquisition by CFM, the
     Subject Person becomes the Beneficial Owner of any additional Voting
     Securities which increases the percentage of the then outstanding Voting
     Securities Beneficially Owned by the Subject Person, then a Change in
     Control shall occur.

          (e) Notwithstanding anything contained in this Agreement to the
     contrary, if Carolin's employment is terminated prior to a Change of
     Control Event and Carolin reasonably demonstrates that such termination (i)
     was at the request of a third party who has indicated an intention or taken
     steps reasonably calculated to effect a Change of Control Event and who
     effectuates a Change of Control Event (a "Third Party") or (ii) otherwise
     occurred in connection with, or in anticipation of, a Change of Control
     Event which actually occurs, then for all purposes of this Agreement, the
     date of a Change of Control Event with respect to Carolin shall mean the
     date immediately prior to the date of such termination of Carolin's
     employment and shall constitute grounds for Termination for good reason by
     Carolin under Section 4(c) of this Agreement.

6.   EXTENDED MEDICAL AND DENTAL BENEFITS

     In the event of an event of Termination under Section 4(a), 4(c) or 4(d) of
this Agreement, Carolin and Carolin's dependents shall receive continued
provision of CFM's standard employee medical and dental benefits or comparable
benefits under the plans of Successors and Assigns for thirty (30) months.
Notwithstanding the foregoing, in the event Carolin becomes covered as a primary
insured (that is, not as a beneficiary under a spouse's plan) under another
employer's group health plan during the extended benefit period provided for
herein, Carolin shall promptly inform Successors and Assigns and Successors and
Assigns shall cease provision of continued group health benefits for Carolin and
any dependents.

7.   FEDERAL EXCISE TAX UNDER IRC SECTION 280G

          (a) If (1) any amounts payable under this Agreement are characterized
     as excess parachute payments pursuant to Section 4999 of the Internal
     Revenue Code, and (2) Carolin thereby would be subject to any United States
     federal excise tax due to that characterization, then (3) Carolin may
     elect, in Carolin's sole discretion, to reduce the amounts payable under
     this Agreement or to have any portion of applicable options not be granted
     or vest in order to avoid any "excess parachute payment" under Section
     280(G)(b)(1) of the Internal Revenue Code of 1986, as amended.

                                       7

<PAGE>

          (b) Unless Successors and Assigns and Carolin otherwise agree in
     writing, any determination required under this Section 6 shall be made in
     writing by independent public accountants agreed to by Successors and
     Assigns and Carolin (the "Accountants"), whose determination shall be
     conclusive and binding upon Successors and Assigns and Carolin for all
     purposes. For purposes of making the calculations required by this Section
     6, the Accountants may rely on reasonable, good faith interpretations
     concerning the application of Sections 280G and 4999 of the Code.
     Successors and Assigns and Carolin shall furnish to the Accountants such
     information and documents as the Accountants may reasonably request in
     order to make the required determinations. Successors and Assigns shall
     bear all fees and expenses the Accountants may reasonably charge in
     connection with the services contemplated by this Section 7.

8.   RELEASE OF CLAIMS

     Successors and Assigns may condition payment of the termination benefits
described in Sections 4(a), 4(c), 4(d) and 6 of this Agreement upon the delivery
by Carolin of a signed release of claims in a form reasonably satisfactory to
Successors and Assigns; provided, however, that Carolin shall not be required to
release any rights Carolin may have to be indemnified by CFM or Successors and
Assigns.

9.   NON-COMPETITION AND NON-SOLICITATION

     During the term of Carolin's employment and any period during which
post-Termination compensation may be received, Carolin agrees not to (1) engage
in (as an employee, consultant, director, principal, partner, officer, agent,
advisor or otherwise) or be financially interested in any business operating
anywhere in the world which, in the reasonable judgment of Successors and
Assigns, directly competes with Successors and Assigns through the design,
manufacture or distribution of semiconductor wet processing equipment or (2)
directly or indirectly solicit, induce, encourage, or attempt to influence any
client, customer, employee, consultant, independent contractor, salesman, or
supplier of Successors and Assigns to cease to do business or terminate his
employment with Successors and Assigns.

10.  NOTICES

     Any notice or other communication under this Agreement shall be in writing
and shall be deemed to have been given: (i) upon delivery when delivered
personally against receipt therefor; (ii) one (1) day after being sent by
Federal Express or similar overnight delivery; or (iii) three (3) days after
being mailed via registered or certified mail, postage prepaid, return receipt
requested, to either party at the address set forth above, or to such other
address as such party shall give by notice hereunder to the other party.

11.  SEVERABILITY OF PROVISIONS

     If any provision of this Agreement shall be declared by a court of
competent jurisdiction to be invalid, illegal or incapable of being enforced in
whole or in part, such provision shall be interpreted so as to remain
enforceable to the maximum extent permissible consistent with applicable law and
the remaining conditions and provisions or portions thereof shall nevertheless
remain in full force and effect and enforceable to the extent they are valid,
legal and enforceable, and no provision shall be deemed dependent upon any other
covenant or provision unless so expressed herein.

12.  ARBITRATION

     With the exception of actions to enforce the terms of Section 9, any
dispute or disagreement arising out of this Agreement or a claimed breach, shall
be resolved by arbitration in Chester County, Pennsylvania under the National
Rules for the Resolution of Employment Disputes of the American Arbitration
Association, each party to bear its own costs. The arbitrator's decision shall
be final and binding upon the parties and judgment may be entered in any court.

13.  SUCCESSORS

     This Agreement shall be binding upon and shall inure to the benefit of CFM,
its successors and assigns and CFM shall require any successors and assigns to
expressly assume and agree, in writing, to perform this Agreement in the same
manner and to the same extent that CFM would be required to perform it if no
such succession or assignment had taken place.

14.  ENTIRE AGREEMENT MODIFICATION

     This Agreement contains the entire agreement of the parties relating to the
subject matter hereof and the parties hereto have made no agreements,
representations or warranties relating to the subject matter of this Agreement
which are not set forth herein. No modification of this Agreement shall be valid
unless made in writing and signed by the parties hereto.

15.  BINDING EFFECT

                     AMENDMENT NO. 1 TO EMPLOYMENT AGREEMENT

     Amendment (hereinafter "Amendment") dated as of April 10, 2000 to a certain
Employee Agreement (the "Agreement") dated October 25, 1999, by and between CFM
Technologies, Inc., a Pennsylvania Business Corporation having a place of
business at 150 Oaklands Blvd., Exton, PA 19341 and Lorin J. Randall, an
individual residing at 120 S. Wawaset Road, West Chester, PA 19382.

                                   WITNESSETH:

     WHEREAS, based upon a continuing desire to motivate Randall's continued
employment, and in recognition of Randall's continuing contribution to the
Company;

     NOW, THEREFORE, in consideration of the foregoing and the mutual promises
and covenants contained in the Agreement and herein, and intending to be legally
bound hereby, it is agreed to delete Section 5 of the Agreement, in its
entirety, and replace it with the following:

5.   TERMINATION

          Randall's employment hereunder began on or about January 9, 1995 and
     shall continue until terminated upon the first to occur of the following
     events:

               (a) THE DEATH OR DISABILITY OF RANDALL. CFM may, at its option,
          terminate Randall's employment for "disability" (as hereinafter
          defined). In the event of termination for death or disability, Randall
          or his designated beneficiary, shall be entitled to termination
          benefits pursuant to Paragraph 5(d), which monthly benefits shall be
          reduced in each month such benefit may be received by any amounts
          received by Randall from disability insurance during such month from a
          program provided by CFM. For purposes of this Agreement, the term
          "disability" means any physical or mental illness, impairment or
          incapacity which prevents Randall from performing, with or without
          accommodation, the essential functions of his position hereunder for a
          period totaling not less than one hundred eighty (180) days during any
          period of twelve (12) consecutive months.

               (b) TERMINATION BY THE BOARD OF DIRECTORS OF CFM FOR CAUSE. Any
          of the following actions by Randall shall constitute cause:

               (i)  Material breach by Randall of the provisions of the CFM
                    Non-Disclosure and Invention Agreement which he is a party
                    to, provided that Randall has received written notice of
                    such breach from the President or a member of the Board of
                    Directors of CFM, has had an opportunity to respond to the
                    notice in a meeting and has failed to substantially cure
                    such breach or neglect within thirty (30) days of such
                    notice; or

<PAGE>

               (ii) Theft; a material act of dishonesty or fraud; intentional
                    falsification of any employment or Company records; or the
                    commission of any criminal act which impairs Randall's
                    ability to perform appropriate employment duties under this
                    Agreement; or

              (iii) Randall's conviction (including any plea of guilty or nolo
                    contendere) for a crime involving moral turpitude causing
                    material harm to the reputation and standing of the CFM; or

               (iv) Gross negligence or willful misconduct in the performance of
                    Randall's assigned duties; provided however, that merely
                    unsatisfactory performance by Randall of such duties and
                    responsibilities shall not constitute "cause" for purposes
                    of the Agreement; and provided further that Randall has
                    received written notice of such breach or neglect from the
                    President, Chairman or Board of Directors of CFM, has had an
                    opportunity to respond to the notice in a meeting and has
                    failed to substantially cure such breach or neglect within
                    thirty (30) days of such notice.

          (c) TERMINATION BY RANDALL FOR GOOD REASON. Any of the following
     actions or omissions by CFM shall constitute good reason:

               (i)  Material breach by CFM of any provision of this Agreement
                    which is not cured by CFM within fifteen (15) days of
                    written notice thereof from Randall; or

               (ii) Any action by CFM to intentionally harm Randall; or

              (iii) If following, at any time subsequent to the date of this
                    Agreement, a Change of Control Event and within eighteen
                    (18) months following the date of such Event, a change
                    occurs in Randall's status, title, position, compensation,
                    or responsibilities (including reporting responsibilities)
                    which, in Randall's reasonable judgment, represents a
                    material adverse change from his status, title, position,
                    compensation, or responsibility as provided for in this
                    Agreement, Randall may, at his sole option by providing
                    written notice within sixty (60) days following such change,
                    deem such change to be good reason under this Section 5(c).

               (iv) The failure of CFM to obtain an agreement, satisfactory to
                    Randall, from any Successors and Assigns to assume and agree
                    to perform this Agreement.

                                       2

               (i)  CFM shall give Randall not less than thirty (30) days notice
                    of the termination of his employment without cause and CFM
                    shall have the option of terminating Randall's duties and
                    responsibilities prior to the expiration of the notice
                    period subject to payment by CFM of Randall's then current
                    base pay for the remainder of the notice period;

               (ii) If such Termination shall occur, CFM will pay Randall twelve
                    (12) monthly payments equal to one twelfth of Randall's then
                    current annual base salary plus annual target bonus;

              (iii) If such Termination shall occur within the eighteen (18)
                    month period following a Change of Control Event, CFM shall
                    (1) pay to Randall his target annual bonus for the current

                    Termination, (2) continue to pay Randall monthly
                    compensation equal to one-twelfth of Randall's then current
                    annual base salary plus annual target bonus for a period of
                    eighteen (18) months following the date of Termination.

               (iv) Following a Change of Control Event which shall occur during
                    the one year period following any Termination of Randall
                    under 5(d)(i), above, CFM shall (1) pay to Randall his
                    target annual bonus for the current fiscal year on a pro
                    rata basis corresponding to the date of Termination, (2)
                    continue to pay Randall monthly compensation equal to

                    months following the date of Termination, and

                    (3) grant to Randall fully-vested options to purchase a
                    number of shares of common stock of CFM equal to the number
                    of unvested options held by Randall and cancelled at the
                    time of such Termination (the "Cancelled Options"). The
                    purchase price of each such share shall equal the lowest
                    share purchase price of any of the Cancelled Options or the
                    fair market value of a share of common stock of CFM on the
                    date of the Change of Control Event, whichever shall be
                    lower, and all other terms of such newly granted options
                    shall be substantially similar to the terms of the Cancelled
                    Options.

     wishes to resign, he shall give not less than thirty (30) days prior notice
     of such resignation and CFM shall have the option of terminating Randall's
     duties and responsibilities at any time prior to Randall's proposed
     termination date, subject to payment by CFM of the lesser of Randall's then
     current base pay for a thirty (30) day period, or such other period as may
     remain under the notice given by Randall.

     IN WITNESS WHEREOF, the parties hereto. intending to be legally bound
hereby, have executed this Amendment as of the day and year first above written.
