from the Company at the price specified in Section 5. The Plan is intended to be

         (b) "Recognized Compensation" means wages within the meaning of Section
         3401(a) of the Code for purposes of federal income tax withholding at
         the source but determined without regard to any rules that limit the
         remuneration included in wages based on the nature or location of the
         employment or the services performed (such as the exception for
         agricultural labor in Section 3401(a)(2) of the Code) and paid to the
         Participant by the Employer for the applicable period; subject,
         however, to the following:

                  (i) Included Items. In determining a Participant's Recognized
                  Compensation there shall be included elective contributions
                  made by the Employer on behalf of the Participant that are not
                  includable in gross income under Sections 125, 132(f),
                  402(e)(3), 402(h), 403(b), 414(h)(2) and 457 of the Code
                  including elective contributions authorized by the Participant
                  under a Retirement Savings Election, a cafeteria plan or any
                  other qualified cash or deferred arrangement under Section
                  401(k) of the Code.

                  (ii) Excluded Items. In determining a Participant's Recognized
                  Compensation there shall be excluded all of the following: (A)

                  (B) reimbursements or other expense allowances (including all
                  living and other expenses paid on account of the Participant
                  being on foreign assignment), (C) welfare and fringe benefits
                  (both cash and non-cash) including third-party sick pay (i.e.,

<PAGE>

                  disability insurance benefits), income imputed from insurance
                  coverages and premiums, employee discounts and other similar

                  taken, final payments on account of termination of employment
                  (i.e., severance payments), except that final payments on
                  account of settlement for accrued but unused paid time off
                  shall be taken into account in determining a Participant's
                  Recognized Compensation, (D) moving expenses, (E) deferred
                  compensation (both when deferred and when received), and (F)
                  the value of a qualified or a non-qualified stock option
                  granted to a Participant by the Employer to the extent such
                  value is includable in the Participant's taxable income.

                  (iii) Pre-Participation Employment. Remuneration paid by the
                  Employer attributable to periods prior to the date the
                  Participant became a Participant in the Plan shall not be
                  taken into account in determining the Participant's Recognized
                  Compensation.

                  (iv) Attribution to Periods. A Participant's Recognized
                  Compensation shall be considered attributable to the period in
                  which it is actually paid and not when earned or accrued.

                  (v) Excluded Periods. Amounts received after the Participant's
                  termination of employment shall not be taken into account in
                  determining a Participant's Recognized Compensation.

                  (vi) Multiple Employers. If a Participant is employed by more
                  than one Employer in a Plan Year, a separate amount of
                  Recognized Compensation shall be determined for each Employer.

         member of the Committee will remain a member for the duration of the
         Plan unless such member resigns or is removed earlier by majority vote
         of the Board.

         (f) "Eligible Employee" means an Employee who meets the requirements
         set forth herein for eligibility to participate in the Offering.

         (g) "Employee" means any employee (including officers and directors who
         are also employees) of the Company or its Affiliates. Neither service
         as a Director nor payment of a director's fee shall be sufficient to
         constitute "employment" by the Company or the Affiliate.

                                       2
<PAGE>

         (h) "Fair Market Value" means the value of a share of common stock as
         determined in good faith by the Board. If the security is listed on any
         established stock exchange or traded on the Nasdaq National Market or
         the Nasdaq SmallCap Market, then the Fair Market Value of the security
         shall be the closing sales price (rounded up where necessary to the
         nearest whole cent) for such security as quoted on such exchange or
         market as reported on the official Nasdaq website or reported in The
         Wall Street Journal or such other source as the Board deems reliable.
         If there is no closing sales price quoted for such day, then Fair
         Market Value shall be equal to the average of the closing bid and ask
         prices for such day. If neither closing sale nor closing bid nor ask
         prices are quoted, then Fair Market Value shall be determined based
         upon such information for the previous trading day.

         (i) "Interest" means interest as determined pursuant to Section 5.2.

         or July 1 of each calendar year; provided, however, that the initial
         Purchase Period under this Plan shall commence on the day prior to the
         effective date of the Company's initial public offering (i.e., the day
         that the Company's offering is "priced" with the underwriters) rather
         than July 1.

         (l) "Stock" means the common stock, $.01 par value, of the Company.

Section 3.  Stock Subject to the Plan

part, of authorized but unissued Stock not reserved for any other purpose.

3.2 Adjustment in Capitalization. In the event of any change in the outstanding
shares of Stock by reason of a Stock dividend or split, combination,
recapitalization, or reclassification, the shares of Stock issuable and the
price payable therefor under this Plan shall be appropriately adjusted by the
Committee, whose determination shall be conclusive. Except as provided above, no
adjustment shall be made in connection with the issuance by the Company of any
Stock or any warrants, rights, or options to acquire shares of Stock or of
securities convertible into Stock.

Section 4.  Participation

4.1 Eligibility. Rights to participate hereunder shall be granted to employees
of the Company and, as approved by the Board, its Affiliates, provided, however,
that employees whose customary employment is twenty (20) hours or less per week
or whose customary employment is for not more than five (5) months in any
calendar year shall have no right to participate and shall not qualify as
Eligible Employees. An Eligible Employee may elect to become a Participant on
the first day of any Purchase Period, provided such Participant was an Eligible
Employee on the

                                       3
<PAGE>

day immediately preceding the first day of such Purchase Period. Any election to
participate shall be made in accordance with rules adopted by the Committee.
However, in no event shall an Eligible Employee be granted the right to purchase
Stock under the Plan if after the purchase such Eligible Employee would own
stock of the Company possessing 5% or more of the total combined voting power or
value of all classes of stock of the Company. Also, an Eligible Employee may not
become or remain a Participant at any time when such Eligible Employee owns
stock possessing 5% or more of the total combined voting power or value of all
classes of stock of the Company. For purposes of this subsection, the rules of
Section 424(d) of the Code shall apply in determining the stock ownership of an
individual, and stock which an employee may purchase under outstanding options
shall be treated as stock owned by the employee.

4.2 The Board may provide that each person who, during the course of an
Offering, first becomes an Eligible Employee will, on a date or dates specified
in the Offering which coincides with the day on which such person becomes an
Eligible Employee or which occurs thereafter, receive a right to participate
under that Offering, which right to participate shall thereafter be deemed to be
a part of that Offering. Such right to participate shall have the same
characteristics as an rights to participate originally granted under that
Offering, as described herein, except that:

         (a) the date on which such right to participate is granted shall be the
         "Offering Date" of such right for all purposes, including determination
         of the exercise price of such right;

         (b) the period of the Offering with respect to such right to
         participate shall begin on its Offering Date and end coincident with
         the end of such Offering; and

         (c) the Board may provide that if such person first becomes an Eligible
         Employee within a specified period of time before the end of the
         Offering, he or she will not receive any right to participate under
         that Offering.

Section 5.  Purchase of Stock

5.1 Contributions for Purchase of Stock. At the time an Eligible Employee elects
to become a Participant in the Plan, such Eligible Employee shall also elect the
form and manner of contributing funds for the purpose of Stock. A Participant
may elect to contribute funds for the purchase of Stock by directing his or her
employer to withhold any whole percentage less than or equal to 10% of his or
her Recognized Compensation for the purpose of purchasing Stock from the
Company. In no event shall the aggregate contributions for the purchase of Stock
exceed 10% of a Participant's Recognized Compensation. A Participant may modify
the rate of withholding from such Participant's Recognized Compensation only in
accordance with the following:

         (a) A Participant may at any time direct reduction of the rate of
         withholding to a rate lower than that previously in effect. However,
         only one such direction to continue withholding at a rate lower than
         that previously in effect may be made in any one Purchase Period.

                                       4
<PAGE>

         (b) A Participant may at any time direct discontinuance of withholding.
         If a Participant directs discontinuance of withholding, such
         Participant may direct resumption of withholding only as of the first
         day of any subsequent Purchase Period.

         (c) Except as provided in subsection (a) or (b) above, a Participant
         may direct modification of the rate of withholding only as of the first
         day of any Purchase Period. The modified rate may be any whole
         percentage less than or equal to 10% of the Participant's Recognized
         Compensation. Unless otherwise elected by the Participant, the rate of
         withholding such Participant has elected will remain in effect for
         subsequent Purchase Periods.

Any election or direction under this section shall be made in writing pursuant
to rules adopted by the Committee and shall become effective at a time specified
by the Committee.

5.2 Disposition of Contributions. Amounts withheld pursuant to Section 5.1 shall
be held by the employer until the end of the Purchase Period during which they
were withheld, subject to the following:

         (a) A Participant who elects pursuant to Section 5.1(b) to discontinue
         withholding may at any time withdraw all or any part of the amounts
         previously withheld or otherwise contributed. Any such withdrawal shall
         be paid to the Participant by his or her employer in cash with
         Interest.

         (b) During the last calendar month of each Purchase Period, each
         Participant shall be permitted to elect to have all or any part of the
         amounts withheld paid to such Participant in cash with Interest.

         (c) Any withdrawal under (a) or (b) above shall be deemed to be on a
         first-in-first-out basis. Interest shall be applied to the average
         amount in the Participant's account at the end of each full calendar
         month during the completed portion of the Purchase Period. Prior to the
         first day of any Purchase Period, the Committee shall determine the
         rate of Interest with respect to such Purchase Period. The Committee
         shall give such publicity to said Interest rate as it deems
         appropriate.

         (d) Any portion of the amounts withheld that is not paid to the
         Participant in cash shall be automatically applied to purchase Stock
         under Section 5.3.

         (e) Any election or direction under this section shall be made in
         writing pursuant to rules adopted by the Committee.

5.3 Purchases of Stock. Amounts withheld from a Participant during a Purchase
Period (except any amounts refunded to such Participant in cash under Section
5.2) shall be used as of the last business day of such Purchase Period to
purchase Stock from the Company for a price equal to the lesser of (a) or (b).

                                       5
<PAGE>

         (a) 85% of the Fair Market Value of a share of Stock on the first
         business day of the Purchase Period.

         (b) 85% of the Fair Market Value of a share of Stock on the last
         business day of the Purchase Period.

5.4 Issuance of Stock. Promptly after the end of each Purchase Period, a
certificate for the number of shares of Stock purchased by all Participants
shall be issued and delivered to an agent selected by the Company. The agent
will hold such certificate for the benefit of all participants who have
purchased shares of Stock and will maintain an account for each Participant
reflecting the number of shares (including fractional shares, if any) credited
to the account of each Participant. Each Participant will be entitled to direct
the voting of all shares credited to such Participant's account by the agent and
may also direct the agent to sell such shares and distribute the net proceeds of
the sale to the Participant. At any time, a Participant may either request that
the agent transfer the shares of Stock credited to the Participant's account to
another custodian or request from the agent a physical certificate representing
the shares of Stock credited to the Participant's account; provided, however,
that the agent shall not be required to issue a certificate representing a
fractional share and may instead pay the Participant a cash amount representing
the fair market value of such fractional share.

5.5 Privileges of a Stockholder. A Participant shall not have stockholder
privileges with respect to any Stock until the date of issuance of a certificate
to such Participant for such Stock.

5.6 Limitation on Stock Purchases. As required by Section 423 of the Code, no
Participant may purchase Stock under this Plan and all other employee stock
purchase plans of the Company and its Affiliates at a rate in excess of $25,000
in Fair Market Value of such Stock (determined at the time the option to
purchase Stock is granted) for each calendar year in which any such option to
purchase Stock granted to such Participant is outstanding at any time.
Notwithstanding the foregoing, the Fair Market Value (determined on the first
day of any Purchase Period) of shares of Stock that may be purchased by a
Participant during such Purchase Period shall not exceed the excess, if any, of
(i) $25,000 over (ii) the Fair Market Value (determined on the first day of the
relevant Purchase Period) of shares of Stock previously acquired by the
Participant in any prior Purchase Period during such calendar year.

Section 6.  Termination of Employment

6.1 Termination of Employment. A Participant whose termination of employment
occurs more than three months prior to the close of a Purchase Period will not
be eligible to purchase any shares of Stock pursuant to this Plan with respect
to such Purchase Period. Any amount withheld from such a Participant during the
Purchase Period in which his or her termination of employment occurs shall be
paid to such Participant in cash with Interest calculated under Section 5.2(c)
as soon as administratively feasible after such Participant's termination of
employment. Any Participant whose termination of employment occurs within three
months prior to the last day of a Purchase Period may direct Stock purchases or
withdrawals with respect to that Purchase Period pursuant to Sections 5.2 and
5.3. However, if a Participant's death occurred at any time during the Purchase
Period, any amount withheld from the Participant

                                       6
<PAGE>

during such Purchase Period shall be paid to the Participant's personal
representative in cash with Interest determined under Section 5.2(c), and no
portion thereof shall be applied to purchase Stock.

Section 7.  Rights of Employees; Participants

7.1 Employment. Nothing in this Plan shall interfere with or limit in any way
the right of the Company or any of its Affiliates to terminate any Employee's,
Eligible Employee's, or Participant's employment at any time, nor confer upon
any such person any right to continue in the employ of the Company or any of its
Affiliates.

7.2 Nontransferability. No right or interest of any Participant in this Plan
shall be assignable, transferable, or subject to any lien, directly or
indirectly, by operation of law, or otherwise, including execution, levy,
garnishment, attachment, pledge, or bankruptcy. Any attempted assignment,
transfer, pledge or other disposition of any rights under the Plan shall be null
and void and shall automatically terminate all rights of a Participant under the
Plan.

Section 8.  Administration

8.1 Administration. The Committee shall be responsible for the administration of
the Plan. The Committee, by majority action thereof, is authorized to interpret
the Plan, to prescribe, amend, and rescind rules and regulations relating to the
Plan, to provide for conditions and assurances deemed necessary or advisable to
protect the interests of the Company and to make all other determinations
necessary or advisable for the administration of the Plan, but only to the
extent not contrary to the express provisions of the Plan. The determination of
the Committee, interpretation or other action made or taken pursuant to the
provisions of the Plan shall be final and shall be binding and conclusive for
all purposes and upon all persons.

Section 9.  Amendment, Modification, and Termination of Plan

9.1 Amendment, Modification, and Termination of the Plan. The Board, upon
recommendation of the Committee, at any time may terminate, and at any time and
from time to time and in any respect, may amend or modify the Plan, provided,
however, that no such action of the Board, without approval of the stockholders

                            CONFIDENTIALITY AGREEMENT

     FLUOROWARE, INC. ("Recipient") has requested RTP Company ("RTP") to provide
certain specific technical and other information ("Material Information") highly
confidential to RTP regarding the following RTP materials ("Materials"):

COMPOUNDS FOR STAT PRO(R) 3000 LS
---------------------------------

     Because of the extremely sensitive nature of the Material Information, this
agreement shall exclusively govern Recipient's obligations regarding use and
nondisclosure of the Material Information, whether or not labeled as
confidential. Any samples of the Material shall be deemed Confidential Samples,
use and disclosure of which are also restricted below.

     1. Recipient's Obligations

          a) Recipient will use the Material Information solely in connection
     with and for the purpose of:

          Approving RTP's materials for use in recipient's production processes
          at its facility in Chaska, MN.

     Without limitation of the foregoing, Recipient may not use the Material
     Information to produce, or assist any other person to produce products
     competitive with the Materials. Recipient shall not disclose the Material
     Information to any person outside of Recipient, whether another Recipient
     supplier, a competitor of RTP, a customer of Recipient or otherwise.

          b) Confidential Samples shall be used solely for testing in connection
     with the Permitted Purpose and in no case shall they be analyzed for
     content, sold or made available to any other person.

          c) Within Recipient, Recipient shall protect and keep confidential the
     Material Information with the highest degree of care and shall disclose it
     solely to Recipient employees with a need to know for the Permitted
     Purpose. Recipient shall be responsible for enforcing this agreement for
     the benefit of RTP.

          d) All documents containing the Material Information (whether
     delivered by RTP or prepared by Recipient) are and will remain RTP's
     property. At RTP's written request, Recipient must promptly return to RTP
     all those materials and any copies promptly at RTP's request. Recipient's
     obligations under this Agreement will last indefinitely.

     2. Exclusions. Recipient's obligations under this Agreement shall not apply
to information which:

          a. is or becomes known to the public through no fault of Recipient or
     its employees;

                                      -9-

          b. is already known to Recipient prior to its receipt as shown by the
     written records of Recipient (but Recipient acknowledges that the requested
     information is not now known to Recipient); or

          c. becomes known to Recipient by disclosure from a third party who has
     a lawful right to disclose the information.

     3. Entire Agreement. This is the complete Agreement between the parties
regarding the treatment of the Material Information and Confidential Samples,
and may be changed only by a written amendment.
