     subcontract any portion of the effort without the prior written
     concurrence of the Sponsor.


E.   CONFIDENTIAL MATERIAL

     i.   In the Project Description and during the performance of this
          Agreement, the Sponsor has and may from time-to-time furnish material
          to the University and Researchers (collectively, "Recipients") that
          Sponsor considers to be of a confidential nature (herein "Sponsor
          Confidential Information").  The Recipients have signed the
          Confidentiality Agreement, under which they will safeguard all such
          material in accordance therewith.  Confidential material not consumed
          in the performance of the research Project shall be returned to, or
          disposed of, as directed by the Sponsor.  Confidential material will
          not be published by the University in student theses, scholarly
          dissertations, or otherwise without prior written consent of the
          Sponsor (and in any event will only be published subject to the
          conditions in Paragraph F. below).

     ii.  Sponsor hereby grants a license to Recipients to use Sponsor
          Confidential Information for the limited and sole purpose of carrying
          out the research goals of the Project (the "Research License"),
          subject to the terms and conditions of the Confidentiality Agreement.
          The Research License shall automatically expire at the end of the
          Term.  The Research License does not include the grant of any
          license, right or interest in or to Sponsor Confidential Information,
          the information in the Project Description, or other Sponsor
          Intellectual Property (as defined in Paragraph G. below).  Sponsor
          expressly retains all other rights in Sponsor Intellectual Property,
          including the exclusive right to commercially exploit the same.

F.   PUBLICATION

     i.   The Sponsor acknowledges that a major consideration in the University
          entering into this Agreement is the ability to publish Student theses
          and scholarly papers derived from the research for the Project
          (herein, "Project Research").   University acknowledges that major
          considerations for the Sponsor in entering into this Agreement are
          for Sponsor (a) to preserve the patentability of Sponsor's ideas and
          inventions set forth in or contemplated by the Project Description or
          conceived in whole or in part by Sponsor from the Project; (b) to
          preserve the confidentiality of Sponsor Confidential Information and
          Sponsor's other trade secrets; and (c) to retain the exclusive right
          to exploit such ideas, inventions, and other Sponsor Intellectual
          Property (as defined in Paragraph G. below).  Accordingly, University
          and Sponsor have agreed on the conditions set forth in clauses ii. -
          v. of this Paragraph F to set forth their agreement about publication
          rights for Project Research.

     ii.  There shall be no publication by University or any Researcher of any
          Project Research before December 16, 1998 (the "Earliest Publication
          Date").  In addition, (a) there shall be no publication of Invention-
          Related Research (as hereinafter defined) except in accordance with
          clauses iii., iv. and v. below; (b) there shall be no publication of
          Project Research other than Invention-Related Research (herein "Other
          Project Research") except in accordance with clause v. below; and (c)
          in the event research includes information that is both Invention-
          Related Research and Other Project Research, it shall be deemed for
          purposes of this Agreement to be Invention-Related Research.
     
     iii. After the expiration of the Term and subject to Paragraph G.i.
          below,, Sponsor shall make reasonable efforts to inform University
          whether Sponsor regards any of Sponsor's Inventions and/or Joint
          Inventions (each as defined in Paragraph G. below) as patentable and
          whether Sponsor desires to perfect, or reserve the right to perfect,
          patents therefor.

     iv.  If University or any of the Researchers desire to publish any
          information relating, directly or indirectly, to the Sponsor's
          Inventions, Joint Inventions and/ or related Project Research
          (collectively herein, "Invention-Related Research"), it/he/she shall
          give Sponsor written notice (the "Publication Notice"), not before
          the Earliest Publication Date and at least nine months prior to the
          desired publication, in order to give Sponsor sufficient time to
          prepare and file patent applications, perfect such patents, and take
          other measures to protect Sponsor Intellectual Property.  Any and all
          Publication Notices shall identify the specific Invention and
          Invention-Related Research that are the subject of the desired
          publication.  During (each) such ninth month period, neither the
          University nor any of the Researchers shall publish (or otherwise
          disclose) any such Invention-Related Research.

     v.   Subject to (x) the Earliest Publication Date provision in clause ii.
          above, and (y) the conditions in clauses iii. and iv. above with
          respect to Invention-Related Research, Sponsor agrees not to unduly
          restrict publication of Project Research; provided that, the
          University shall provide drafts of all articles and other documents
          to the Sponsor for review prior to publication.  Such review shall be
          for the purposes of ensuring that the publication does not disclose
          Sponsor Confidential Information or impair Sponsor Intellectual
          Property, and for providing appropriate protection for Inventions.
          The Sponsor shall provide the University with the results of its
          review within 60 days. Subject to the conditions in clauses ii.-iv
          above, the University may assume de facto agreement to publishing if
          no comments are received within this period.

     vi.  Sponsor may publish, either jointly with University or one or more
          Researchers, or on its own, any part or all of the Project Research,
          after giving at least 30 days advance written notice to University;
          provided that, if during such thirty (30) day period University
          and/or Researcher(s) give written notice to Sponsor of their desire
          to collaborate in such Sponsor publication, Sponsor shall make
          reasonable efforts to reach agreement on the terms of such
          collaboration with University and/or Researcher(s), as the case may
          be; provided further that, if the parties agree to collaborate on
          such publication, it shall be subject in any event to clauses ii.-v.
          above.

G.   PATENTS , INVENTIONS AND INTELLECTUAL PROPERTY

     i.   For purposes of this Agreement, the term "Inventions" means any and
          all patentable inventions, ideas and conceptions (whether for
          products, processes, or both) set forth in or derived from the
          Project Description and/or the Project.  Each of Sponsor and
          University, and each of the Researchers, shall keep and preserve
          contemporaneous notes and other customary records in reasonable
          detail of all Inventions.  After the expiration of the Term and upon
          request of either party, each party shall provide to the other (a) a
          list of all Inventions; and (b) its characterization of each
          Invention as one of the following: a Sponsor's Invention (as defined
          in clause (ii) below), a Joint Invention (as defined in clause (v)
          below), or University Project IP (as defined in clause (iv) below).
          Thereafter, if either party questions the other's characterization of
          one or more Inventions, the other party shall promptly submit a
          written explanation of its reasons for each such characterization(s).
          The parties shall work in good faith to agree on the appropriate
          characterization of any Invention(s) about which a dispute may arise.

     ii.  For purposes of this Agreement, the term "Sponsor Intellectual
          Property" means Sponsor Confidential Information; Inventions
          conceived or created solely by Sponsor (herein "Sponsor's
          Inventions"); and Sponsor's other trade secrets, proprietary
          information and other intellectual property (whether owned, acquired
          or developed prior to, during or after the Term).

     iii. Except for the limited Research License granted in Paragraph E.ii.
          above, Sponsor retains all title, ownership, and exclusive right to
          exploit Sponsor Intellectual Property.

     iv.  With respect to Inventions and other intellectual property conceived
          or created solely by the Researchers or University in connection with
          or as the result of the Project (herein, "University Project IP"),
          University shall retain title and ownership of the same.   At its
          election, Sponsor shall acquire, and University shall grant to
          Sponsor, a worldwide exclusive perpetual license to exploit and use
          the University Project IP pursuant to one of the two options set
          forth in subclause (a) or (b) below:

          (a)  Sponsor may acquire a paid-up license, wherein following
               completion of the Project but in any event before commercial
               exploitation of the University Project IP, Sponsor shall pay
               University a single lump-sum amount of $120,000; or
          (b)  Sponsor may acquire a license, in consideration for such other
               license or royalty fee (whether paid-up, calculated on a
               percentage basis, or otherwise) on which the parties may reach
               agreement in the future following good faith negotiation but
               before commercial exploitation of the University Project IP.

          In any event, if the University Project IP for which Sponsor seeks a
          license is patentable, Sponsor shall pay all patenting costs
          therefor.

v.   With respect to Inventions and other intellectual property conceived or
     created jointly by the Sponsor, on the one hand, and the Researchers
     and/or University, on the other hand (such Inventions herein "Joint
     Inventions", and such intellectual property herein "Joint IP"), Sponsor
     and University shall jointly own the Joint Inventions and other Joint IP.
     At its election, Sponsor shall acquire, and University shall grant to
     Sponsor, a worldwide exclusive perpetual license to exploit and use the
     Joint Inventions and other Joint IP (herein a "Joint IP License") pursuant
     to one of the two options set forth in subclause  (a) or (b) below:

          (a)  Sponsor may acquire a paid-up license, wherein following
               completion of the Project but in any event before commercial
               exploitation of the Joint Inventions or other Joint IP (as the
               case may be), Sponsor shall pay University a single lump-sum
               amount of $60,000; or
          (b)  Sponsor may acquire a license, in consideration for such other
               license or royalty fee (whether paid-up, calculated on a
               percentage basis, or otherwise) on which the parties may reach
               agreement in the future following good faith negotiation but
               before commercial exploitation of the Joint Inventions or other
               Joint IP (as the case may be).

     Except in the event Sponsor duly elects and acquires a Joint IP License
     pursuant to subclause (a) or (b) above, Sponsor and University shall have
     the joint right to exploit Joint Inventions and other Joint IP.
     
     For purposes of this clause v., it is understood and agreed that any and
     all Inventions and/or other intellectual property embodied in the Project
     Description constitute Sponsor Intellectual Property, and shall not be
     deemed to be Joint Inventions or other Joint IP.

     In any event, if the Joint Invention(s) for which Sponsor seeks a Joint IP
     License is/are patentable, Sponsor shall pay all patenting costs therefor.


H.   PUBLICITY

     Neither party to this Agreement shall mention the other party in
     advertising or publicity of any manner without first obtaining the written
     permission of the other party, which party shall have the right in its
     discretion to withhold or grant permission, or to grant its permission
     subject to conditions it deems appropriate.

I.   TERMINATION

     Either party may terminate this Agreement "for cause", if the breach of
     the other party's obligation(s) or other "cause" has not been cured by the
     other party after thirty (30) days written notice specifying the breach,
     event or other cause and demanding its cure.  In the event of termination,
     the University will take immediate action to mitigate the costs incurred
     under this Agreement and, the Sponsor shall pay all reasonable costs (up
     to, but not exceeding, the amount accrued under the schedule in Paragraph
     C.i. of this Agreement) incurred by the University prior to the effective
     date of termination.  Reasonableness of cost shall be determined by
     applying those rules in Office of Management and Budget (OMB) Circular A-
     21 in effect at the date of last signature of this Agreement.  In the
     event the payments by the Sponsor exceed the reasonable cost or accrued
     scheduled payments, the University shall promptly reimburse the excess
     payments to the Sponsor.

J.   LIMITS OF LIABILITY

     The University is and will be acting as an independent contractor in the
     performance of this Agreement, and it shall be solely responsible where
     found liable for the payment of any and all claims for loss, personal
     injury, death, property damage, or otherwise, arising out of any act or
     omission of its employees or agents, including the Researchers, in
     connection with the performance of this Agreement.

Dear Jim:

Attached for your consideration is an R&D concept whose execution at VPI could
significantly advance our understanding of cure chemistries and composite
morphology for fluoroelastomer/fluoroplastic microparticulate blends.

This work may well be one that could be conducted by a graduate student with the
available analytical and processing resources and expertise available at VPI,
resources which we do not presently have.

I hope we can discuss that possibility during my visit to VPI with John Verbicky
on Friday, September 19, 1997.

Best regards,



John Effenberger
Director of R&D




PROPOSED PROGRAM:   CHEMFAB/VPI STUDIES OF MICROPARTICULATE BLENDS OF
                    FLUOROPOLYMERS

Background

The potential for obtaining new forms of polymeric compositions with novel and
commercially attractive performance features by blending separately polymerized
polymers in aqueous microparticulate (sub-micron sized) forms is under
investigation at Chemfab Corporation.  Such simple blends lend themselves to
isolation by removal of water to yield processible solids in physical forms such
as thin cast films (including multi-layer films) and coarse, but readily
compressible agglomerates, both of which can be further processed through
relatively low temperature, low pressure forming (such as compression molding or
extrusion at 100 degrees C).  Such blending facilitates the incorporation of
elastomeric and/or thermoplastic polymers with each other, as well as with
homogeneously distributed,  finely divided, fillers or reactive chemicals, (e.g.
rubber curatives or co-agents).

It is believed that such a process can yield attractive combinations of elasto-
plastic mechanical behavior in finished parts while exhibiting a broad range of
physical properties including wear, abrasion, and frictional characteristics,
chemical resistance and thermal range in end-use.

Since the reactivity of elastomeric constituents with curative components is
likely to play a significant role in determining both finished properties and
process rheology, it is desirable to identify preferred curatives for specific
polymeric compositions and to observe their effect on both process rheology and
morphological changes taking place during the process.

Program

Fixing polymeric composition to include a single fluoroelastomer (Fluorel (R)
terpolymer) and no more than two fluoroplastics (PTFE and FEP), at a fixed
relative abundance of fluoroelastomer  (60 weight percent), it is an objective
to identify at least two preferred curatives for such blended compositions:  one
should be water soluble for compatibility with solids isolation from an aqueous
colloid, and the other should be water insoluble  It is highly desirable that
good compression set in "finished" (cured sheet) parts be an important criteria
of acceptable curative performance.   CHEMFAB will provide the latex and
dispersion raw materials.  VPI will identify and procure curatives.

It is also an objective that initial isolation of processible solids from
blended aqueous systems include two isolation methodologies to yield cast film
and "coagulated powder", respectively.  Procedures for both of these isolation
methodologies will be proved by CHEMFAB.

Evaluation of properties of "finished" compositions can be obtained on simple
compression-molded slabs (30-60 mils in thickness).  It is anticipated that the
selection of curative chemistry types will be important determinants of the
actual molding conditions and it is expected that VPI will identify/optimize
them.

Rheological characterization of the isolated solids should include "typical
rubber processing" information (e.g. oscillating disk rheology) as well as
"typical plastic processing information" (e.g. capillary rheology data).
Extrudates from such rheometry can also serve to provide specimens to examine
changes in morphology as a  function of shear rate and temperature.  It is
anticipated that important changes in the PTFE morphology  ("fibrillation"
and/or  orientation) will be observable and to some degree quantifiable as will
the crystalline conditions of the PTFE and FEP.

Slabs of the "finished" compositions can be used for such observations as well
as for characterization of properties such as tensile stress/strain behavior,
degree of swell in methanol, wear and abrasion behavior, durometer, etc., for
both "as made" and heat-aged specimens.

It is hoped that CHEMFAB's initial exploratory efforts and current understanding
of such systems up through isolation of solids will allow VPI to focus on
curative selection and morphological structure as it affects process and
finished part performance.

It is our objective to advance such understanding substantially over the next
four to six months or sooner if possible.  Our own investigations will continue;
we expect from time to time to submit specimens for your morphological
characterization to guide our own efforts as well.

We look forward to a mutually beneficial relationship, and especially to new,
commercially valuable materials.
