                              --------------------


     This Consulting  Agreement (this "Agreement"), dated  as of the  2nd day of
August, 1996, is by and between Chemfab Corporation, a Delaware corporation with
its principal  place of business at  701 Daniel Webster Highway,  Merrimack, New
Hampshire,  on behalf  of  itself and  each  of its  subsidiaries  (hereinafter,
individually and  collectively,  the "Company"),  and  Dr. Nicholas  Pappas,  an
individual   residing  at   606  Swallow   Hollow  Road,   Wilmington,  Delaware
(hereinafter, "Consultant").

     WHEREAS,  the Company  desires  to  extend  and broaden  its  technologies,
business operations  and commercial  activities to include  materials, products,
processes, applications and capabilities that are materially different from, but
synergistic with, those  currently produced,  sold, practiced, and  used by  the
Company;

     WHEREAS, the  Company  recognizes  that such  broadening  of  its  existing
technologies, business operations and commercial  activities will likely best be
achieved over time from various  sources that are both internal and  external to
the Company;

     WHEREAS, the Company further recognizes that any such external sources will
likely   result  from  transactions  such  as,  but  not  limited  to,  business
acquisitions,  joint ventures  and  other strategic  alliances, licenses,  joint
development arrangements,  joint marketing arrangements or  similar arrangements
(each, hereinafter, a "Strategic Alliance");

     WHEREAS,  Consultant is highly qualified  to assist the  Company in finding
and entering into Strategic Alliances which constitute Diversifying Arrangements
(as defined below) due to his experience, knowledge and contacts in the field of
materials science and in the plastics industry; and

     WHEREAS, the Company desires to engage the services of Consultant to assist
it  in  finding and  entering  into  Diversifying  Arrangements, and  Consultant
desires to provide said services to the Company as an  independent contractor to
the Company;

     NOW,  THEREFORE,  in  consideration of  the  foregoing  and  of the  mutual
undertakings hereinafter set forth, the parties hereto agree as follows:

but synergistic with, those that are  produced, sold, practiced, and used by the
Company as of the date hereof.

     Section 1.2    "Diversifying   Acquisition"   shall  mean   a  Diversifying

     Section 1.3    "Control" shall mean with  respect to any Unrelated Business
Entity the  power to direct  the affairs  of such Unrelated  Business Entity  by
reason of ownership of voting stock or other equity interests  of such Unrelated
Business Entity (or of another entity having the  power to direct the affairs of
such Unrelated  Business Entity) or  by reason  of ownership of  assets of  such
Unrelated Business Entity.

     Section 1.4    "Unrelated  Business  Entity"  shall  mean  any corporation,
operating division  of  a  corporation, or  other  established  business  entity
theretofore unaffiliated with and unrelated to the Company.

     Section 1.5    "Alternative  Diversifying  Arrangement"   shall  mean   any
Diversifying Arrangement,  other than  a Diversifying Acquisition,  entered into
between the Company and any Unrelated Legal Entity (as defined below) that is of
such  significance and  importance to the  Company that  it is  submitted to and
approved by the Company's Board  of Directors (with Consultant, in his  capacity
as a  director, abstaining from any vote thereon) by resolution adopted prior to
the Closing Date with respect thereto.

     Section 1.6    "Unrelated Legal  Entity" shall mean  any Unrelated Business
Entity  or  any  natural   person  or  group  of  natural   persons  theretofore
unaffiliated with and unrelated to the Company.

     Section 1.7    "Closing  Date"  shall mean  in the  case of  a Diversifying
Acquisition the  legal closing  date for  the transaction  by which the  Company
acquires Control  of  the Unrelated  Business  Entity, and  in  the case  of  an
Alternative Diversifying Arrangement the  date the contractual agreement(s) that
establish  the  date  of  such Alternative  Diversifying  Arrangement  become(s)
legally binding on the parties under applicable law.

     Section 1.8    "Lead" shall mean any  specific business opportunity or idea
involving a specified  Unrelated Legal Entity  that is  (1) originated or  first

Company  as  a  possible transaction  that  may,  if  consummated, constitute  a
Diversifying  Arrangement, and  (3) confirmed  in writing  by Consultant  to the
Company  as  soon  as practicable  after  it  is  originated  or  identified  by
Consultant.

     Section 1.9    "Qualifying Lead" shall mean any Lead with respect to  which
Consultant is  not informed in writing  by the Company, within  twenty (20) days
after the date  of the Company's receipt of Consultant's written confirmation of

          (a)  In the case  of a proposed Diversifying Acquisition,  the Company
had identified the relevant Unrelated Business Entity as a potential subject  of
a Diversifying Acquisition  prior to the initial disclosure of  such Lead to the
Company by Consultant, as shown by written records in existence  at that time or
as evidenced by corroborating certifications or testimony by one or more Company
employees or third parties, or

          (b)  In the  case of a proposed  Alternative Diversifying Arrangement,
the Company had identified the relevant specific business opportunity or idea as
a potential Alternative Diversifying Arrangement prior to the initial disclosure

          (a)  If,  as  a result  of any  Qualifying  Lead from  Consultant, the
Company consummates a Diversifying Acquisition for which the Closing Date occurs
within  twenty-four (24)  months  after the  date of  the  Company's receipt  of
Consultant's  written confirmation of the related Lead, then, subject to Section
4.2(c) hereof, the Company shall grant Consultant, on the tenth  (10th) business
day  following such Closing Date, an option (an "Option") to purchase forty-five
thousand  (45,000) shares of the Company's Common Stock; provided; however, that
if  Consultant previously received an  Option, pursuant to  Section 4.2(b), with
respect to the same Unrelated Business Entity with which the Company consummated
such Diversifying Acquisition, then the Option granted to Consultant pursuant to
this Section 4.2(a) shall be an Option to purchase twenty-five thousand (25,000)
shares of the Company's Common Stock.

          (b)  If,  as  a result  of any  Qualifying  Lead from  Consultant, the
Company  consummates  an  Alternative  Diversifying Arrangement  for  which  the
Closing  Date  occurs within  twenty-four  (24) months  after  the  date of  the
Company's  receipt of  Consultant's written  confirmation  of the  related Lead,
then, subject to Section 4.2(c) hereof,  the Company shall grant Consultant,  on
the tenth (10th) business day following such Closing Date, an Option to purchase
twenty thousand (20,000) shares of the Company's Common Stock.

          (c)  No Option  shall be granted  hereunder unless Consultant,  in his
capacity as  Consultant, a director of the Company, or otherwise, is eligible on
the  date of  the grant of  such Option  to receive  non-qualified stock options
under a Company  stock option plan as in effect on  such date (the "Plan").  The
number of shares for which Options may be granted pursuant to this Section  4.2,
and  the number  of  shares  for  which  any Option  is  exercisable,  shall  be

stock splits  or  contractions, reclassifications,  or  similar changes  in  the
Company's Common Stock.

     Section 4.3    Terms  of the  Option.   Any  Option  shall (i)  be  granted
pursuant  to the  Plan as a  non-qualified option,  (ii) have  an exercise price
equal to the  closing price of the Company's  Common Stock on the date  of grant
thereof (or, in the event that no trading of the Company's Common Stock occurred
on  such date,  on the  business day  last preceding  such date  for which  such
information was reported), (iii) vest in full on the date of  grant thereof, and
(v) be  subject to the terms and conditions of  the Plan and an Option Agreement
representing such Option.

     Section 4.4    Responsibility for  Taxes.  All  compensation (including the
grant  of Options)  to be  paid to  Consultant hereunder  shall be  paid without
deduction or  withholding of any  federal, state,  local or  foreign taxes,  and

foreign taxes due with respect thereto and all other deductions required by law.
Consultant agrees to indemnify the Company and hold it harmless from and against
any liability, cost or  expense (including, without limitation, court  costs and
attorney's fees)  resulting from  Consultant's breach  of his obligations  under
