          -------------------                                            
suitable for manufacturing Business Products on cost and schedule terms to be
agreed; provided, however, that:  (i) the cost shall be sufficient to cover OC's
internal and out of pocket costs; and (ii) the schedule will be as expeditious

design of such melter is to be completed within two years of the Effective Date.

     2.3  TI 990 Batch Weigh System Replacement.  OC will provide for COMPANY a
          -------------------------------------                                 
turnkey implementation of a TI 990 Batch Weigh System Replacement for the Aiken,
South Carolina facility at OC's current projected cost of two hundred and forty-
two thousand dollars ($242,000); provided, however, that such current cost

     2.5  CB 83 Chopper. COMPANY acknowledges that the CB 83 Chopper at the
          -------------                                                    
Huntingdon, Pennsylvania facility embodies OC's Confidential Information, and OC
is concerned that such Confidential Information not be disclosed to third
parties.  COMPANY

                                       3

 
further acknowledges that maintenance, support, and spare part fabrication
services for the CB 83 by third parties would necessarily entail disclosure of
such Confidential Information. OC and COMPANY therefore agree that all
maintenance and support services for the CB 83 (including fabrication and supply
of all spare parts) shall be provided by: (i) OC; (ii) COMPANY, subject to the
confidentiality provisions of Article 6 below; or (iii) third party providers
subject to Section 2.6.2 below. COMPANY hereby grants to OC a right of first
refusal to purchase the CB 83 in the event that COMPANY determines to sell the
CB 83.

     2.6  Limitations on OC's Obligations.
          ------------------------------- 

          2.6.1  Personnel Limitations.  COMPANY acknowledges that OC may not
                 ---------------------                                       
always be capable of providing certain of the Services requested by COMPANY, in
that OC is transferring personnel to COMPANY, or may divest its composites
business or otherwise cease its involvement in the composites industry, and for
this and other reasons may not always have appropriate personnel to perform
certain of the Services.  Therefore, except for the Services specified in
Sections 2.2 and 2.3, OC is under no obligation to provide requested Services.

          2.6.2  Use of Third Party Providers and Former OC Employees.  In the
                 ----------------------------------------------------         
event that OC is unable to provide requested Services because of OC's lack of
suitable personnel, or for service of the CB 83 Chopper pursuant to Section 2.5
above, COMPANY may engage the services of third party providers and/or former
employees of OC, subject to the following restrictions:

          (a)  COMPANY shall first enter into, and supply to OC an executed copy
               of, a Confidentiality Agreement substantially in the form
               attached as Exhibit B to this Agreement;

                                       4

 
          (b)    former employees of OC shall not be released from their
                 obligation to preserve the confidentiality of OC proprietary
                 information of which they have knowledge except to the extent
                 reasonably necessary to provide the Services for which they are
                 engaged by COMPANY;

          (c)    any OC proprietary information communicated from former
                 employees of OC to COMPANY shall be subject to the
                 confidentiality provisions of the Patent and Know How License
                 Agreement to be entered into under the SPA (the "License
                 Agreement");

          (d)    unless otherwise agreed by the Parties, this provision shall
                 not entitle COMPANY to access to OC proprietary information to
                 which COMPANY is not otherwise entitled pursuant to the License
                 Agreement; and

          (e)    COMPANY's use of third party providers shall be subject to the
                 provisions of Section 6.6 of the License Agreement.

          2.6.3  Priority.  For as long as COMPANY is an Affiliate of OC, OC
                 --------                                                   
shall accord to COMPANY at least the same priority as OC gives in rendering
services to its other most favored Affiliates and licensees.  Notwithstanding
the foregoing, OC acknowledges that COMPANY shall have a heightened need for the
Services during the six (6) month period following the Effective Date (the
"Transition Period") and OC is committed to facilitating COMPANY's success
during the Transition Period, as well as thereafter.  OC therefore agrees to use
commercially reasonable efforts, consistent with OC's internal operations, to
respond to COMPANY's requests for Services during the Transition Period, and to
give higher priority to

                                       5

 
rendering the Services requested by COMPANY than those of OC's other Affiliates
and licensees.

          2.6.4  Written Work Product.  In the event that COMPANY desires OC to
                 --------------------                                          
prepare any specific designs, drawings, flow sheets, reports, manuals, equipment
specifications, process descriptions, operating procedures, equipment and
process control descriptions, method engineering studies, purchasing studies,
engineering reports or any similar document or report relating to the Services,
such document or report shall be furnished as promptly as circumstances permit,
provided that OC shall not be required to supply any such materials hereunder
that OC determines in its reasonable judgment to have been unreasonably
requested in light of the intent and purposes of this Agreement.

          2.6.5  Restricted Information.  OC shall not be obligated to prepare
                 ----------------------                                       
or furnish any document or report which would disclose any information which OC
is at the time prevented from disclosing to COMPANY by reason of government
regulations, obligations arising from contracts with third parties which are not
Affiliates of OC, or other restrictions of any kind imposed upon OC by a third
party which is not an Affiliate of OC.  Furthermore, nothing in this Agreement
shall authorize the disclosure of, or access to, or obligate OC to provide or
make available, classified or restricted information, material or know-how of
the government of the United States of America.

          2.6.6  No Obligation to Grant a License.  Except as provided in
                 --------------------------------                        
Article 5 of this Agreement, nothing herein shall obligate OC to license or
otherwise transfer any technology to COMPANY.

                                       6

 
     2.7  COMPANY Services.  The Parties contemplate that COMPANY may have or
          ----------------                                                   
develop technical service capabilities of interest to OC, and agree that OC may
request services from COMPANY on the same terms as those applying to the
Services.

3.   WORK ORDERS AND FEES.
     -------------------- 

     3.1  Work Orders.  Individual requests for Services to be performed under
          -----------                                                         
this Agreement shall be defined by a Work Order prepared substantially in the
form of Exhibit A.  Each Work Order shall include a description of the Services
requested, specifications, pricing, delivery and completion schedule, payment
schedule, special terms and conditions applicable to the specific project, a
Statement of Work, and testing and acceptance criteria.  Each Work Order,
together with this Agreement, is a separate contract governed by the terms and
conditions of this Agreement that will be effective as of the date signed by
authorized representatives of both COMPANY and OC.  If any explicit terms of the
Work Order (including the Statement of Work) conflict with the terms of this
Agreement, such explicit terms of the Work Order will take precedence.

     3.2  Changes to Work Orders.  If COMPANY requests or OC recommends changes
          ----------------------                                               
during performance of a Work Order, OC shall provide COMPANY with a written
change order proposal setting forth:  (i) a description of the proposed changes;
(ii) the impact on pricing; (iii) the impact on the project schedule; and (iv) a
revised Statement of Work.  COMPANY may accept or reject any such change order
proposal.  A change order proposal shall be considered rejected if COMPANY does
not accept the change order proposal within ten business days after receipt of
the change order proposal.  If accepted, change orders will be effective upon
execution

                                       7

 
of the change order proposal by COMPANY. Notwithstanding the foregoing, OC and
COMPANY may make minor, non-material modifications to the specifications in the
Work Order provided (i) such modifications do not limit, diminish or
substantially affect the scope of the Services or any work product to be
provided in connection therewith; and (ii) and OC shall promptly notify COMPANY
in writing of such modification and vice-versa.

     3.3  Fees.  Except as the Parties may mutually agree pursuant to an
          ----                                                          
individual Work Order, COMPANY agrees to pay OC for the Services at OC's
standard rates then in effect which OC charges to its most favored Affiliates or
licensees for such Services, as well as all reasonable, actual traveling and
living expenses incurred by OC's personnel in connection with providing the
Services.  Such fees shall be paid according to the payment schedule defined in
the relevant Work Order.  Notwithstanding the foregoing, but subject to Sections
2.2, 2.3 and 2.4, COMPANY shall pay OC for Services provided during the
Transition Period on the same cost basis on which OC accounts for its internal
capital projects.  If OC engages the services of third parties to provide
requested Services, OC shall charge COMPANY for reimbursement of the charges of
such third parties, without surcharge.

4.   COOPERATION.  The Parties agree that representatives of each Party shall
     -----------                                                             
meet every six (6) months, beginning in January, 1999, to discuss each Party's
technical developments during the preceding six (6) month period.  Such
discussions shall be conducted pursuant to an agenda to be agreed by the parties
at least three (3) weeks before each such meeting.  Neither Party shall be
required to disclose information about its developments in any more detail than
is reasonably necessary to inform the other Party of the general nature and
practical applications of

                                       8

 
any such developments to the manufacture of Business Products. Such meetings are
intended to inform each Party of technical developments that may be of interest
for potential licensing or provision of related Services. Neither Party shall be
obligated to supply more detailed information, to license any technology related
to any disclosed development, or to provide Services related to any disclosed
development. Each Party may submit a report annually to COMPANY's Board of
Directors on the respective Party's assessment of the conduct and results of the
meetings held during the preceding year.

5.  INTELLECTUAL PROPERTY.  Except as the Parties may otherwise agree, OC shall

but not limited to, copyrights, patents, and trade secrets, created by OC in the
performance of Services for COMPANY.  The foregoing intellectual property rights
include, but are not limited to:  (i) all rights to register, or to renew any

Copyright Office, the U.S. Patent and Trademark Office, or in any foreign
counterparts to those U.S. offices.  Notwithstanding anything explicit or
implied to the contrary in this Agreement, all intellectual property created by
OC in the rendering of Services under this Agreement shall constitute Seller
Licensed Know How and/or Seller Licensed Patents, as appropriate, under the
License Agreement and be governed by the terms and

                                       9

 
provisions of the License Agreement which shall govern COMPANY's and OC's use of
and rights to such intellectual property. The parties agree that COMPANY's use
of such intellectual property shall be royalty-free.

use, except for purposes expressly licensed under this Agreement, any
Confidential Information obtained directly or indirectly from Discloser.
