                            Research and Development

                  A.  In  order  to  enhance  its   ability  to  obtain   future
sublicenses  and in  consideration  of  reduced  royalty  rates  from  Licensor,
Licensee  hereby  agrees to  continue,  at its own  expense,  its  research  and
development activities,  both at its Technical Center in Granville, Ohio, and at
its various plants and other locations,  as a contractor to Licensor.  Ownership
of  all  rights  associated  with  technology  developed   thereunder,   whether
patentable or not, shall vest  immediately and solely in Licensor,  and Licensee
shall have no rights  therein except as provided by this License  Agreement.  In
addition,   Licensee  shall  continue  to  develop,  at  its  own  expense,  new
Trademarks,  Trade Names and Service Marks, and such shall also vest immediately
and solely in Licensor.



                  B. In  further  consideration  of reduced  royalty  rates from
Licensor,  Licensee agrees to employ or retain qualified  personnel,  at its own
expense,  to provide  administrative  and other  support  for the  research  and
development  activities  described  immediately  above  during  the term of this
Agreement.  Such personnel may include,  but not be limited to, patent  counsel,

                                   ARTICLE IV
                                 Effective Date


                  This Agreement shall be effective as of October 1, 1991.



                                    ARTICLE V
                                    Royalties


                  A.  Commencing  on the  Effective  Date and  continuing  for a
period of twenty (20) years thereafter, Licensee shall pay to Licensor royalties
on Net Sales in the amounts set forth on Schedule C attached  hereto;  provided,
however,  that  either  Licensor or Licensee  may, on each  anniversary  of this
Agreement,  request an  independent  study to  determine  current  arm's  length
royalty rates.  The cost of such study shall be divided equally between Licensor
and Licensee and, upon completion of such study, the royalty rates in Schedule C
shall be adjusted  effective as of the  anniversary  date on which the study was
requested.



                  B.  Where  Products  contain  more  than one type of  Licensor
technology,  royalties  shall be paid on the  component  Product(s)  separately,
applying the relevant royalty rate to each component Product and to the finished
Product,  respectively.  By way  of  example,  where  roofing  Products  contain
fiberglass  reinforcements,  Licensee shall pay a reinforcements  royalty on the
arm's-length  value of the  reinforcements  which are  contained in the finished
Product and a roofing  royalty on the revenues  generated by actual sales of the
finished Products.



C.       For the purpose of calculating Net Sales, Products shall be considered
sold:

         1.       if sold on open account,  when  delivered to the  purchaser
                  or to a common  carrier and consigned to the purchaser.

         2.       if paid in advance of delivery, when paid for;

         3.       if sold on  consignment,  when  paid for by the  consignee or
                  when  released  from  consignment, whichever shall first
                  occur; or

         4.       if sold internally,  when delivered to the Licensee  division
                  responsible for  manufacturing the finished Product.



                  Royalties  shall be  computed  for each  calendar  quarter and
shall be  payable  thirty  (30) days after the end of each  calendar  quarter by
electronic  funds  transfer to a bank account to be  designated by Licensor from
time to time.



                  D. Whenever  royalties  have been paid by Licensee on Products
sold and such  Products are lost or damaged in transit,  or are not accepted and
paid for by a purchaser,  or are returned or an allowance or credit is given for
them because of their condition of defective  quality,  or because of shortages,
or because of inability  to collect  after one year from the sale to a purchaser
(recoveries  thereafter to be regarded as new sales),  then,  unless Licensee is
reimbursed therefor by insurance or other source of recovery, the royalties paid
on such Products  shall be charged back or deducted from further  payments to be
made but only to the extent pro rata that such Products are not paid for or used
or Licensee is not otherwise reimbursed therefor.



<PAGE>




                  E. Licensee shall keep true and accurate  records and books of
accounts  containing  all  data  reasonably  required  for the  computation  and
verification of royalties to be paid as herein provided, which records and books
shall at all reasonable  times during business hours be available for inspection
and  copying by Licensor  or  Licensor's  independent  auditor.  Any  inspection
hereunder  shall be upon reasonable  notice to Licensee.  Licensee shall provide
Licensor  within twenty (20) days after the end of each calendar  quarter with a
statement of its Net Sales by product for the calendar quarter.


                                   ARTICLE VI
                                    Payments


                  A. All  Licensee  payments  to Licensor  under this  Agreement
shall be made by electronic funds transfer to a bank account to be designated by
Licensor from time to time, United States dollars.



                  B. The unpaid balance of amounts  payable under this Agreement
shall bear interest at the prime rate charged by major  commercial  banks in the
United States for the period  commencing on the date such amount becomes payable
and ending on the date such balance is paid in full.



                  C.   Licensee   shall  bear  all   taxes,   duties  and  other
governmental charges in any jurisdiction or agency or authority thereof relating
to or arising under this Agreement,  including, without limitation, any stamp or
documentary taxes, value added taxes,  turnover,  sales or use taxes,  excise or
income taxes,  including income taxes imposed on Licensor, and withholding taxes
on royalties and other payments payable to Licensor hereunder.



                                   ARTICLE VII
               Certain Representations and Warranties of Licensor


                  A. Licensor makes no representation or warranty of any nature,
and none  shall be  implied,  (i) as to the  validity  or scope of the  Licensor
Patents,  (ii) that  either (x) the  practice of the  inventions  claimed in the
Licensor Patents,  (y) the use of Licensor Know-How,  or (z) anything made, used
or sold or  otherwise  disposed of under the license  granted by the Licensor to
Licensee in this  Agreement,  will not infringe any patent or other right of any
third  party,  or  (iii)  as to the  usefulness,  utility  or  fitness  for  any
particular or intended purpose, whether of Licensee or any customer of Licensee,
of any Licensor Patent or Licensor Know-How,  or any Product produced therewith,
including,  without  limitation,  the  ability of  Licensee  to adapt any of the
Licensor  Patents or  Licensor  Know-How  to its needs,  whether or not known to
Licensor, or to manufacture, use or sell Products using the Licensor Patents and
Licensor Know-How.



                  B.       Licensor makes no representation  or warranty of any
nature,  and none shall be implied, as to the validity or scope of any other
Licensor Intellectual Property.



                                  ARTICLE VIII
           Ownership and Protection of Licensor Intellectual Property


                  A. The Licensor  Intellectual Property licensed by Licensor to
Licensee under this Agreement shall be and remain the property of Licensor,  and
Licensee  acknowledges  and  agrees  that  Licensor  is and  shall at all  times
continue  to be the owner  thereof.  Licensor  may impose such  conditions  with
respect  thereto as Licensor  may deem  reasonably  necessary  to  preserve  the
confidential  nature  of any  Intellectual  Property  to which  restrictions  of
subparagraph B of this Article VIII apply.



                  B. Except as expressly  permitted by this Agreement,  Licensee
shall retain all Intellectual  Property  licensed to it in strict  confidence as
trade  secrets of Licensor  and shall not  disclose,  or permit any  employee or
agent of Licensee to  disclose,  any such  Intellectual  Property to any person,
firm or  corporation  without the prior written  approval of Licensor,  provided
that  such  disclosure  may be  made  to any  employee  of  Licensee  who  has a
reasonable need for access thereto for the purposes of installing, operating and
maintaining the Intellectual  Property  licensed under this Agreement so long as
Licensee  imposes  identical  obligations  on  such  employee  to  maintain  the
confidentiality  of such  Intellectual  Property.  Licensee  shall  exercise all
necessary precautions to safeguard the secrecy of Intellectual Property licensed
to it and to prevent the unauthorized disclosure or use thereof.  Licensee shall
consult  with  Licensor as to the  procedures  established  by Licensee for this
purpose that Licensee then has in effect.  Licensee  shall be liable to Licensor
for any disclosures or uses of Intellectual Property, directly or indirectly, by
any employee of Licensee or other person or entity not authorized by Licensor in
advance.  The obligations of confidentiality of Licensee under this subparagraph
B shall  not  apply  to  Intellectual  Property,  which  (i) has  become  public
knowledge  through no breach of this Agreement,  or (ii) has been made available
to Licensee by third parties without any breach of confidence on their part.



                  C.       Upon the  termination  of this Agreement  pursuant to
Article XI hereof,  all rights and privileges of Licensee hereunder shall
terminate and revert to Licensor.



                  D.  It is the  specific  intent  of the  parties  hereto  that
nothing  contained herein shall in any way endanger any right of Licensor in and
to any Licensor Intellectual Property licensed by Licensor to Licensee hereunder
and should any  provision or provisions of this  Agreement be  interpreted  by a
court or tribunal or other  governmental  authority so as to endanger such right
or  rights,  whether  or not  such  interpretation  is made at the  instance  of
Licensee  or  another,  then,  at the  option of  Licensor,  such  provision  or
provisions  shall be deemed deleted from this Agreement or this Agreement  shall
be immediately  terminated in respect of all or any of the Licensor Intellectual
Property so interpreted to be endangered.



                  E. Licensee shall, at its own expense, use its best efforts to
discover any infringements,  misappropriations or other unauthorized uses of the
Intellectual  Property  licensed  to it  hereunder  and  shall  promptly  notify
Licensor  in  writing  of  any  such  infringement,  misappropriation  or  other
unauthorized use. Licensee shall, on behalf of Licensor,  have the obligation to
bring, at its own expenses,  any appropriate  action to prevent or terminate any
such  infringement,  misappropriation  or other  unauthorized  use.  If any such
action is brought,  Licensee,  after consultation with Licensor, shall have full
control over the  prosecution  and  settlement  or compromise of such action and
shall assume all the expenses in respect of such  action.  Licensor  shall fully
cooperate with and assist  Licensee in any such action.  Licensee shall not take
any action in protection of the rights of or in  furtherance  of the interest of
Licensor without Licensor's authorization.



                  F.       Licensee  shall,  at its own  expense,  take such
other  actions as are  appropriate  to preserve the value of the Intellectual
Property.


                                   ARTICLE IX
                                     Claims


                  A. Except as specifically  set forth herein,  Licensor and its
Affiliates  shall have no liability to Licensee or any  Affiliates  of Licensee,
and Licensee  releases  Licensor and the Affiliates of Licensor from any and all
liability  to Licensee or any  Affiliate of  Licensee,  and Licensee  waives any
right  against  Licensor or the  Affiliates  of  Licensor  for  contribution  or
indemnity  arising from any  liability to Licensee or any Affiliate of Licensee,
in connection  with the  manufacture,  distribution,  sale or use of Products by
Licensee, or any customer of Licensee, with the aid of the Licensor Intellectual
Property.  Licensee  is not an agent or  partner  of,  or  joint  venturer  with
Licensor under this Agreement.  Licensee shall have no right, power or authority
to accept summons or legal process for Licensor or the Affiliates of Licensor.



                  B. Licensee shall indemnify and hold harmless Licensor and the
Affiliates of Licensor from and against all loss, expense (including  attorneys'
fees and  disbursements),  damage or liability  to Licensor or any  Affiliate of
Licensor  arising  out of (i)  the  manufacture,  distribution,  sale  or use of
Products  by, or for,  Licensee;  and (ii) any  representation  made or warranty
given by  Licensee  with  respect to any  Product,  except in those  cases where
Licensor  has  expressly  authorized  Licensee  to make such  representation  or
warranty.



                  C. Licensee shall have sole control over, and shall assume all
expenses with respect to, the defense,  settlement,  adjustment or compromise of
any  claim as to which  this  Article  IX  requires  it to  indemnify  Licensor,
provided,  however,  that (i)  Licensee  shall  acknowledge  its  obligation  to
indemnify  and hold  harmless  Licensor and the  Affiliates of Licensor from and
against any loss, expense (including attorney's fees and disbursements),  damage
or liability  to Licensor or the  Affiliates  of Licensor  arising from (x) such
claim,  and (y) any claim against  Licensor or any Affiliate of Licensor arising
from the facts and  circumstances  that gave rise to such claim,  (ii)  Licensor
may,  if it so  desires,  employ  counsel  at its own  expense  to assist in the
handling of such claim,  and (iii)  Licensee  shall obtain the prior approval of
Licensor before  entering into any settlement,  adjustment or compromise of such
claim or ceasing to defend  against  such  claim,  if  pursuant  thereto or as a
result thereof there would be imposed upon Licensor  injunctive  relief or money
damages in an amount which  Licensee  would or could not pay in full,  or if any
such  settlement,  adjustment  or  compromise  does not  include as a  condition
thereof an absolute and  unconditional  release of Licensor  and its  Affiliates
from all further liability in connection with such claim.

                                    ARTICLE X
                               Further Assurances


                  A. Each party  hereto shall  promptly  execute and deliver all
such other agreements,  certificates instruments or documents and do and perform
or cause to be done and  performed  all such  further  acts and things as may be
reasonably  requested by the other party hereto in order to carry out the intent
and  purposes  of  this  Agreement  and  the  consummation  of the  transactions
contemplated hereby.

                  B. Anything in this Agreement to the contrary notwithstanding,
no  licenses,  implied or  otherwise,  are granted to any party other than those
granted to the parties hereto pursuant to Article II hereof, and other than such
licenses  granted to such  parties,  no license is granted or  undertaken  to be
granted, and no act of manufacture, use or sale shall be construed as, or result
in, a grant of any license to either party hereto or any third party,  expressly
or by inplication,  estoppel, or otherwise, under or with respect to any letters
patent or know-how now or hereafter owned or controlled by either party.



                                   ARTICLE XI
                                      Term


                  A. This Agreement shall become  effective  pursuant to Article
IV hereof,  and unless sooner  terminated  pursuant to the terms  hereof,  shall
continue in effect for twenty (20) years  thereafter.  The  expiration  or prior
termination  of this  Agreement  for any reason  shall not  entitle  Licensee to
indemnity payments,  termination charges or damages of any nature whatsoever due
to, or incurred by, Licensee,  including,  without limitation,  damages based on
Licensee's reliance, presumed in law or otherwise, on the further continuance of
this Agreement, or based on any goodwill, presumed in law or otherwise,  created
by Licensee with respect to the Products  manufactured,  distributed  or sold by
Licensee hereunder.



                  B.       This  Agreement  and all rights  hereunder  may be
terminated  by Licensor  and without limiting the liability of Licensee
hereunder forthwith upon written notice to Licensee in the event that:



         1.       There shall be a cessation  of  operations  by Licensee or the
                  institution by or against Licensee of any proceeding  (whether
                  voluntary or  judicially  ordered) in  bankruptcy or of or for
                  dissolution,    liquidation,   winding   up,   reorganization,
                  arrangement  or the  appointment  of a  receiver,  trustee  or
                  judicial  administrator (or the equivalent  thereof in France)
                  or any  other  proceeding  under  any law for  the  relief  of
                  debtors;

         2.       Licensee  shall make an  assignment  for the  benefit of, or
                  composition  or  arrangement  with, creditors  or admit in
                  writing  its  inability  to pay its debts as they  become
                  due or fail to clear any check or note when presented for
                  payment;

         3.       Licensee  shall have  failed to pay any amount due and payable
                  to  Licensor  hereunder  or shall  have  breached  a  material
                  obligation  hereunder,  or shall  otherwise  have  committed a
                  default  hereunder  and Licensee  shall not have remedied such
                  default (and given  written  notice to Licensor  specifying in
                  detail the specific  steps taken to effect the remedy)  within
                  30 days after receipt of notice of such default from Licensor;

         4.       Licensee  shall  have  discontinued  its  business  or its
                  business  shall  be  expropriated  or nationalized,  or there
                  shall be a material  change in the  ownership,  management
                  or control of Licensee or a material portion of its assets; or

         5.       Licensee  shall  purport to assign its rights and  obligations
hereunder in violation of Article XII hereof.



                  Licensee  will  notify  Licensor  as soon as it  learns of any
information that would, in the reasonable  judgement of Licensee,  lead Licensee
to determine that a material  change in the ownership,  management or control of
Licensee or of such assets, as described in subsection 4 of this subparagraph B,
would be likely.



                  C. If Licensor elects to terminate this Agreement  pursuant to
subparagraph  B of this Article XI,  Licensee shall cease to  manufacture,  use,
sell or distribute any Products hereunder,  or to enter into any sublicenses for
the use of Licensor Intellectual  Property. The failure of Licensor to terminate
the Agreement for any of the reasons specified in subparagraph B of this Article
XI shall  not in any way be  deemed a waiver of  Licensor's  rights  in  respect
thereof or  otherwise  limit its right to enforce  the  obligations  of Licensee
hereunder.

party,  provided that either party may assign this  Agreement to another  entity
controlling,  controlled by or under common  control with the  assigning  party,

substituted therefor by proper notice hereunder.



                  C. The terms  and  conditions  herein  constitute  the  entire
agreement  between the parties,  and supersede any and all previous  agreements,
with respect to the subject matter hereof. No agreement or understanding varying
or extending this  Agreement  shall be binding unless in writing and signed by a
duly  authorized  officer or  representative  of each party and in which writing
express reference is made to this Agreement.



                  D.  Any  provision  of this  Agreement  which  is  prohibited,
unenforceable or invalid in any jurisdiction shall, as to such jurisdiction,  be
ineffective only to the minimum extent of such prohibition,  unenforceability or
invalidity without affecting the remaining  provisions  hereof.  With respect to
the release from liability and indemnification of Licensor and the Affiliates of
Licensor  by Licensee  under  Article IX of this  Agreement,  to the extent such
provisions are  prohibited,  unenforceable  or invalid,  this Agreement shall be
deemed to have been  amended to modify such  provision or to include a provision
or provisions which permit the broadcast release and the maximum indemnification
permitted  by  applicable  law under  the  circumstances  or,  at the  option of
Licensor, this Agreement shall be immediately  terminated.  No such prohibition,
unenforceability  or invalidity in any  jurisdiction  shall invalidate or render
unenforceable such provision in any other jurisdiction.



                  E. The failure of either party hereto to enforce, or the delay
by either party in enforcing,  any of its rights under this Agreement  shall not
be deemed a continuing  waiver or a  modification  thereof and either party may,
within the time provided by applicable law, commence  apprpriate legal action to
enforce any or all of such rights.



                  F.       The section  headings of this Agreement are for
convenience of reference only and shall not in any way modify, interpret or
construe the intentions of the parties.



                  G.       This Agreement may be executed in several
counterparts,  all of which shall  constitute one and the same instrument.



                  H. If either of the parties is prevented  from  performing the
Agreement by cases of Force  Majeure,  including,  but not  restricted  to, war,
serious fire, strike, labor dispute,  flood,  typhoon,  earthquake,  embargo, or
other  substantially  serious  events beyond the control of either party,  or as
agreed upon between the two parties,  the time for  performance of the Agreement
shall  be  extended  by a period  equal to the  effect  of such  cases,  and the
obligations  and rights of both parties under this Agreement  shall be postponed
by a period equal to the effect of such cases, provided that the default rate os
interest  provided in Article  VII,  subparagraph  B, shall not be  postponed or
extended.  The prevented  party shall notify the other party within the shortest
possible  time of the  occurrence of the Force  Majeure.  Should the effect of a
Force Majeure continue more than one hundred and twenty (120)  consecutive days,
both  parties  shall settle the further  performance  of the  Agreement  through
friendly  negotiations  as soon as possible.  If either party believes that such
negotiation is  impracticable  or determines that  negotiation does not make any
progress, it may refer the matter to arbitration.

instrument  to be executed in duplicate by their duly  authorized  and empowered

                         AMENDMENT TO LICENSE AGREEMENT

         This  amendment  is  entered  by and  between  Owens-Corning  Fiberglas
Technology,  Inc. 7734 West 59th Street,  Summit,  Illinois 60501 (LICENSOR) and
Owens-Corning  Fiberglas  Corporation,   Fiberglas  Tower,  Toledo,  Ohio  43659
(LICENSEE).

         WHEREAS, LICENSOR and LICENSEE have entered a License Agreement dated
October 1, 1991;

         WHEREAS,  LICENSOR and LICENSEE  desire to amend the aforesaid  License
Agreement such amendment being effective to October 1, 1991;

         NOW THEREFORE,  in consideration  of the mutual  covenants  hereinafter
provided,  and for other good and  valuable  consideration,  receipt of which is
hereby acknowledged, the parties agree as follows:

         Article II of the Agreement is hereby  amended to include the following
paragraph:


         C. (i) Licensee  warrants  that all  Products and Services  bearing the
         Licensed  Marks shall be of a nature that will be  consistent  with the
         high  standards of quality and  excellence  established  over the years
         with  respect to the  Licensed  Marks.  Licensee  shall comply with any
         quality  standards  that Licensor may set from time to time with regard
         to the Products and/or Services.


         (ii) Upon  written  request  by  Licensor,  Licensee  shall  furnish to
         Licensor a reasonable number of representative  samples of the Products
         to permit  Licensor to determine  that such  Products  meet the quality
         standards  set forth herein.  Licensor  shall have the right to inspect
         Licensee's  places of  business to assure  compliance  with the quality
         standards  established  by  Licensor.  If so  notified  in  writing  by
         Licensor, Licensee shall not offer or provide any Products whose nature
         or quality does not comply with the quality  standards  established  by
         Licensor.

         (iii)  Licensee  shall  comply  with such  standards  as  Licensor  may
         establish  from time to time with respect to the style,  appearance and
         manner of use of the  Licensed  Marks.  Upon the  request of  Licensor,
         copies  or  accurate  reproductions  of all  materials  displaying  the
         Licensed Marks such as labels,  advertising and promotional  materials,
         letterhead,  business  cards,  signs and the like,  shall be provide to
         Licensor  for review as to form and  content.  Licensee  shall cease or
         modify  in  accordance  with  Licensor's  instructions  any  use of the
         Licensed  Marks  that  Licensor  deems  not be in  compliance  with its
         standards.

         (iv) In the event Licensor  determines that the quality of the products
         being  distributed  by  Licensee  do not  meet the  quality  standards,
         Licensor shall so notify Licensee in writing and Licensee shall correct
         such  quality.  In the event  Licensee  fails to correct such  quality,
         Licensor may terminate the License Agreement upon written notice.

         (v) Licensor  expressly  reserves the right from time to time to modify
         or change the Licensed  Marks.  The Licensed  Marks,  as so modified or
         changed,  shall for all  purposes  be deemed to be the  Licensed  Marks
         referred  to in  this  Agreement.  Any and all  such  modifications  or
         changes in said Licensed  marks  developed or adopted by Licensor shall
         be the sole and absolute property of Licensor,  and Licensor shall have
         the  exclusive  right to register such modified or changed marks in the
         United States.  Licensee may propose  changes to the Licensed Marks for
         adoption and approval by Licensor.

         The Agreement shall remain in full force and effect except as expressly
modified by this Amendment.

         IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
duly executed this 8th day of December 1993.
