prospective client databases, access codes and similar security information and
procedures, and all patents, copyrights, maskworks, trade secrets and other

Information" shall not include any of the foregoing that is in the public domain
other than as the result of a breach of an obligation of confidentiality.
<PAGE>
     D. Employee recognizes that any unauthorized use or disclosure of
Confidential Information would cause serious injury to Company, and that the
Company's willingness to employ Employee depends upon Employee's commitment to
protect Company's Confidential Information and to comply with all of the
provisions of this Agreement

                                    Agreement

     Therefore, for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Company and Employee hereby agrees as
follows.

     1. Protection of the Confidential Information. At all times during and
after Employee's employment, Employee shall hold all Confidential Information in
confidence and shall protect it with utmost care. Employee shall not disclose,
retain, copy, or permit any unauthorized person to disclose or copy any of the
Confidential Information, except as may be necessary for the conduct of the
Company's business. Employee shall not use any of the Confidential Information
except as necessary to perform Employee's duties as an employee of the Company
as provided in this Agreement and in the Employment Agreement.

     2. Confidential Information Belonging to Third Parties. In the event that
Employee has or has had access to any Confidential Information belonging to any
third party, including but not limited to any of Employee's previous employers,
Employee shall hold all such Confidential Information in confidence and shall
comply with the terms of all agreements between Employee or Company and any
third party with respect to such Confidential Information.

     3. Exceptions. This Agreement is not to prevent the use or disclosure by
Employee of information that (a) is required by law to be disclosed, but only to
the extent that such disclosure is legally required, (b) becomes a part of the
public knowledge other than by a breach of an obligation of confidentiality, or
(c) is rightfully received from a third party and neither the Company nor
Employee is obligated to hold such information confidential.

     4. Return of Confidential Information. Upon the Company's request, and in
any event upon termination of Employee's employment by the Company for any
reason, Employee shall promptly return to Company all materials in Employee's or
possession or control that contain or represent Confidential Information,
including but not limited to documents, drawings, diagrams, flow charts,
computer programs or files, memoranda, notes, and every other medium, and all
copies thereof. Under the above stated conditions, the Company shall return all
that it received from Employee as set forth in Exhibit A upon return of the
consideration paid to the Employee for said items by the Company.

                                       2

     5. Non-Competition.

          (a) Acknowledgement. Employee acknowledges that (i) the Company and/or
     its affiliated and subsidiary organizations are engaged in a variety of
     business endeavors; including development of applications for mixing
     liquids and gases in small particle sizes (the "Business"); (ii) the
     Business is conducted throughout the United States and is expected to be
     conducted in one or more countries internationally; (iii) Employee's work
     for the Company will give Employee access to trade secrets and confidential
     information concerning the Company and the Business, including, without
     limitation, proprietary information and trade secrets, investor addresses
     and contact lists, techniques for raising development capital for the
     Company; (iv) the ability of the Company and its affiliates to continue the
     Business is likely to be materially jeopardized and the value of the
     Company and its affiliates reduced if Employee competes with, or assists
     other persons in competing, with the Company and/or any of its affiliates.

          (b) Covenant Not to Compete. Therefore, for a period of 3 years from
     the date of any termination of Employee's employment by the Company for any
     reason, Employee shall not anywhere in the world, accept employment with or
     render any service to a direct competitor of the Company in the polymer
     industry or create or engage in creating or conducting a competing business
     in the polymer industry.

               (i) "Direct Competitor" and "competing business" for purposes of
          this Agreement mean any business or entity that is in any business
          that is the same or similar to the Business.

               (ii) Employee acknowledges that the restrictions imposed by this
          Agreement are reasonable and will not preclude Employee from being
          gainfully employed other than in the polymer industry, in other ways
          and activities following a termination of employment with the Company.

                                       3
<PAGE>
               (iii) Without limiting the foregoing, Employee also agrees that,
          during the Term of the Employment Agreement, and for a period of 3
          years after termination of the Employment Agreement, Employee shall
          not do any of the following: carry on any business or activity
          (whether directly or indirectly, as a partner, shareholder, owner,
          principal, agent, director, affiliate, employee, advisor, or
          consultant, or in any other capacity) which is competitive with the
          polymer Business as conducted by the Company at the time of
          termination of Employee's employment.

          (c) Enforceability. If any court shall determine that the duration,
     geographic limitations, subject or scope of any restriction contained in
     this Section 5 of this Agreement is unenforceable, it is the intention of
     the parties that this Section 5 of this Agreement shall not thereby be
     terminated but shall be deemed amended to the extent required to make it
     valid and enforceable, such amendment to apply only with respect to the
     operation of this Section 5 of this Agreement in the jurisdiction of the
     court that has made the adjudication.

     6. Assignment of Inventions. Employee agrees to disclose and to assign
immediately to the Company, or to any persons designated by the Company, or at
the Company's option, any of the Company's successors or assigns, all inventions
or improvements which are or were made, conceived or reduced to practice by
Employee, whether acting independently or with others, during the course of
Employee's employment with the Company, and which (i) were made, conceived of or
first reduced to practice in the performance of any duties assigned to or
undertaken by the Employee as an employee of the Company; or (ii) were made,
conceived of or first reduced to practice with the use of the Company's time,
material, facilities or funds. Such inventions are referred to herein as
"Inventions."

          (a) This Agreement shall not diminish the effect or binding nature of
     nay prior invention assignments made to the Company by Employee.

          (b) Without limiting the foregoing, at all times the Company (or its
     nominee) shall have the right to obtain, for its own benefit and in its own
     name (and entirely at its expense) patents and patent applications of any
     type, and all renewals and extensions of such patents and applications for
     the inventions and improvements described in this Section.

          (c) In order to protect the right, title and interest of the Company
     (or its successors, assigns or nominees) in such inventions or
     improvements, in connection with any applications or patents necessary to
     convey rights to those improvements or inventions to the Company, Employee
     shall, without further compensation, execute and deliver all papers and
     instruments and perform such further acts, including giving testimony or
     furnishing evidence in the prosecution or defense of appeals,
     interferences, suits and controversies relating to any of the inventions or
     improvements, as may be deemed necessary by the Company.

     7. Additional Cooperation with Respect to Inventions. Employee shall (a)
treat all information with respect to Inventions as Confidential Information
within the meaning of this Agreement; (b) keep complete and accurate records of
the Inventions, which records will be the property of Company; (c) testify in
any proceedings or litigation related to the Inventions; and (d) in case the
Company will desire to keep secret any Inventions or will for any reason decide
not to have letters patent applied for thereon, refrain from disclosing the
Invention and from applying from letters patent thereon.

                                       4
<PAGE>
     8. Assistance of the Company. Without limiting any of the foregoing,
Employee shall assist Company in every way deemed necessary or desirable by
Company (but at the Company's expense) to obtain and enforce patents,
copyrights, trademarks and other rights and protections relating to any
Confidential Information and Inventions in any and all countries, and to that
end Employee will execute all documents for use in obtaining and enforcing such
patents, copyrights, trademarks and other rights and protections as Company may
desire, together with any assignments thereof to Company or persons designated
by it. If Company is unable for any reason to secure Employee's signature to any
document required to apply for or execute any patent, copyright, maskwork or
other applications with respect to any Inventions (including improvements,
renewals, extensions, continuations, divisions or continuations in part
thereof), Employee hereby irrevocably designates Company and its duly authorized
officers and agents as Employee's agents and attorneys-in-fact and on Employee's
behalf to execute and file any such application and to do all other lawfully
permitted acts to further the prosecution and issuance of patents, copyrights,
maskworks or other rights thereon with the same legal force and effect as if
executed by Employee. Employee's obligation to assist the Company shall continue
beyond the termination of Employee's employment, but Company shall compensate
employee at a reasonable rate after Employee's or Employee termination for time
actually spent by Employee at the Company's request on such assistance.

     9. Employee Inventions. Attached as Exhibit A is a list of all Inventions
and information created, discovered, or developed by Employee whether or not
patentable or registrable under patent, copyright or similar statutes, made or
conceived or reduced to practice or learned by Employee, either alone or jointly
with others, excluding any Inventions, relating in any way to the Company's
business or demonstrably anticipated research and development that were made by
Employee prior to Employee's employment with the Company (the "Employee
Inventions"). Employee represents that Exhibit A is complete and contains no
confidential information. Employee understands that Employee has no rights in
any such Employee Inventions other that those listed on Exhibit A. If there is
nothing identified on Exhibit A or if "none" is indicated on Exhibit A, employee
represents that Employee has made no Employee Inventions as of the time of
signing this Agreement. Except as listed on Appendix A which is attached to this
Agreement, Employee will not assert any rights to any inventions, discoveries,
concepts or ideas, or improvements thereof or know-how related thereto, as
having been made or acquired by Employee prior to being employed by the Company,
or since then, and not otherwise covered by the terms of this Agreement.

     10. No Conflicts With Prior Obligations. Employee hereby represents and
warrants that Employee's employment by the Company and Employee's performance of
Employee's obligations under this Agreement will not conflict with any
obligations of any nature or type that Employee has or may have to any third
party or third parties. Employee will not disclose to Company or use in
Company's behalf any confidential or proprietary information belonging to a
third party, unless the third party has consented to the disclosure or use of
the information.

     influence any client of the Company, customer of the Company or other

     or indirectly, in any way that directs or is intended or is likely to
     direct or cause such actual or potential client, customer or other person
     not to purchase the Company's products and /or services.

     12. Equitable Remedies. Employee acknowledges that breach of this Agreement
would cause Company to suffer irreparable harm for which monetary damages would
be inadequate compensation. Employee agrees that Company will be entitled to an
injunction restraining any actual or threatened breach of this Agreement, or
specific performance, if applicable, in addition to any monetary damages.

     13. Employment Relationship. The employment relationship between Employee
and the Company is governed by the Employment Agreement and , as applicable,

this Agreement is attached as an exhibit set forth the entire agreement of the
parties with respect to the subject matter hereof, and supersedes all prior
agreements, whether written or oral.

     15. Waiver and Amendment. This Agreement may be amended only by a writing
signed by both parties hereto. No oral waiver, amendment or modification of this
Agreement shall be effective under any circumstances. The waiver by the Company
of a breach of any provision of this Agreement shall not operate or be construed
as a waiver of any other or subsequent breach of this Agreement by Employee.

     16. Term of Agreement. This Agreement will remain in force during
Employee's employment by the Company and will continue thereafter until all
Confidential Information acquired by Employee becomes part of the public
knowledge other than through a violation of this Agreement.

expiration of this Agreement and termination of the Employment Agreement, for
any reason, for a period of 3 years after termination of the Term of the

<PAGE>
     18. Successors and Assigns. This Agreement may not be assigned by Employee,
but the Company may assign any or all of its rights under this Agreement to any
affiliate or subsidiary company of the Company, so long as the Company remains
liable for the performance by that affiliate or subsidiary of the payment
obligations of the Company hereunder. Except as provided in the preceding
sentence, this Agreement shall be binding upon, and inure to the benefit of, the
parties and their respective personal representatives, successors and assigns.

     19. Severability. Should any provision of this Agreement be considered
unenforceable by a court of law, the remainder of this Agreement shall remain in
force to the fullest extent permitted by law.

     20. Governing Law. This Agreement shall be governed by and interpreted in
accordance with the laws of the State of California, without giving effect to
principles of conflicts of law. Employee hereby consents to the personal
jurisdiction of the state and federal courts located in the State of California

exclusive venue for any such litigation shall be in such courts located in the
State of California.
