       the Development, upon mutual agreement, they may do so; provided,
       however, that

       (a)    neither Graftech nor BPS will, and each of them will ensure that
              its Affiliates will not, and

       (b)    UCAR Carbon will not, and it will ensure that its Affiliates will
              not,

directly or indirectly, undertake such work until two years after the expiry or
earlier termination of the Development Period; provided, however, that either
party may at any time during the Development Period re-propose the work pursuant
to ss.2.7.

ONE PARTY DISCONTINUES WORK

2.9    If either Graftech or BPS (the "Discontinuing Party") wishes to stop
       undertaking any work that is part of the Development (the "Discontinued
       Work"), the following terms and conditions will apply:

       (a)    the Discontinuing Party will give the other party (the "Continuing
              Party") 90 days' written notice of its intention to cease
              undertaking the Discontinued Work,

       (b)    notwithstanding ss.2.6(a), ss.(b) and ss.(d) after the
              expiration of the 90 day notice period, the Continuing Party may
              undertake the Discontinued Work alone or with third parties,

       (c)    the Discontinuing Party will not, and it will ensure that its
              Affiliates will not, undertake the Discontinued Work for the
              remainder of the Development Period or two years after the date of
              its notice to the Continuing Party pursuant to ss.(a), whichever
              is longer; provided, however, that if the Discontinuing Party is
              Graftech, the restriction under this ss.(c) will be equally
              applicable to UCAR Carbon,



                                       15


       (d)    the Discontinuing Party will have no rights to Intellectual
              Property developed by the Continuing Party or its third party
              collaborators in connection with the Discontinued Work after the
              date that the Discontinued Work ceased to be part of the
              Development, and

       (e)    the Continuing Party may not use the Discontinuing Party's
              Confidential Information, or the Discontinuing Party's
              Intellectual Property, in connection with any activity undertaken
              in relation to the Discontinued Work after the date that the
              Discontinued Work ceased to be part of the Development; provided,
              however, that the Continuing Party may use the Joint Arising IP in
              connection with its activities related to the Discontinued Work.

PROVISION OF EQUIPMENT

2.10   Where either Graftech or BPS (the "Requesting Party"), acting reasonably,
       requests specific equipment from the other (the "Donating Party") in
       furtherance of the Development and the Donating Party in good faith,
       determines it necessary to provide such equipment to the Requesting Party
       for the benefit of the Development, the Donating Party will provide such
       equipment to the Requesting Party; provided, however, that

       (a)    the Requesting Party must return such equipment to the Donating
              Party when such equipment is no longer required by the Requesting
              Party and in any event within 30 days after the end of the
              Development Period, and

       (b)    the Requesting Party will be responsible for the costs and other
              incidentals of transportation and set-up of such equipment.

Without limiting the rights of Graftech under this ss.2.10, the parties
acknowledge that BPS will, as soon as is reasonably practicable after the
commencement of the Development Period, provide Graftech with the equipment
listed in Schedule E subject to the terms of this ss.2.10.

SUPPLY AGREEMENT

2.11   The terms of the Supply Agreement will apply to each Graphitic Material
       and Graphitic Component that has passed the [TEXT DELETED] and each other
       Graphitic Material or Graphitic Component specified therein. Each of BPS
       and Graftech will, promptly upon request by the other,

       (a)    execute such deeds, documents and instruments as may be necessary
              to implement the intent of this ss.2.11, and

       (b)    except as otherwise set forth in the Supply Agreement, use all
              commercially reasonable efforts to conclude a supply arrangement
              in respect of such Graphitic Material and Graphitic Component
              within 90 days after such material or component has passed the
              [TEXT DELETED].



                                       16


[TEXT DELETED] FUEL CELLS

2.12   BPS will [TEXT DELETED] the [TEXT DELETED] of [TEXT DELETED] Fuel Cell
       technology pursuant to the Development and will [TEXT DELETED] Graftech
       of its [TEXT DELETED] by [TEXT DELETED]. Graftech will not propose any
       such technology for development pursuant to ss.2.7 until after [TEXT
       DELETED] and accordingly, any refusal by BPS to undertake the development
       of such technology prior to [TEXT DELETED], will be without prejudice to
       BPS's rights to review the situation should Graftech make a proposal,
       after [TEXT DELETED], with respect to such technology under ss.2.7.

DEVELOPMENT EXCEPTIONS

2.13   Notwithstanding anything to the contrary contained in this Agreement or
       the Supply Agreement,

       (a)    UCAR Carbon and its Affiliates may manufacture, make, have made,
              sell or supply non-natural graphite materials, and

       (b)    each of the parties and each of their respective Affiliates may
              collaborate, research, develop, manufacture, make, have made, sell
              or supply devices, subsystems, materials or components whose
              primary function relates to fuel storage devices, power storage
              devices (such as supercapacitors and lithium-ion batteries),
              electronic thermal management components (such as heat sinks, heat
              spreaders and thermal interfaces), electromagnetic interference
              shielding, radio frequency interference shielding and heat
              management devices (such as radiators and components relating to
              reformers) strictly for such primary function,

in each case regardless of whether or not such devices, subsystems, materials or
components are for use in PEM Fuel Cells or PEM Fuel Cell Systems; but for
greater certainty, this provision will not give any rights to any party or any
of such party's Affiliates to, and each party will ensure that its Affiliates
will not, use or disclose any Intellectual Property or Confidential Information
of any other party.

                                     PART 3

                              INTELLECTUAL PROPERTY

ALLOCATION OF IP

3.1    The parties acknowledge and agree that all Intellectual Property
       invented, discovered, improved or otherwise developed pursuant to the
       Development will vest immediately when the same arises and is hereby
       assigned in accordance with the definitions of BPS Arising IP, Graftech
       Arising IP and Joint Arising IP. The parties will execute, or cause to be
       executed, such deeds, documents, instruments and assignments as may be
       necessary to effect and implement the intent of this ss.3.1.



                                       17


IP REGISTRATIONS

3.2    Each party will have the sole, exclusive and unrestricted right to apply
       for, prosecute and obtain all rights, grants, registrations, orders or
       proprietary interests of any nature, including, without limitation,
       patents, copyright, industrial design and trademark registrations and any
       other registrations or grants of rights that are analogous thereto in any
       and all countries throughout the world in respect of the Arising IP
       allocated to it under ss.3.1. Each party will not, and it will ensure
       that none of its employees, agents or Affiliates will, in any manner or
       to any extent, either directly or indirectly, commit any act or omission
       through any means that is inconsistent with a party's rights under this
       ss.3.2. Without limiting the foregoing, no party will, and it will
       ensure that none of its employees, agents or Affiliates will, diminish,
       interfere with or impair any other party's right to the Arising IP
       allocated to it under ss.3.1, whether proprietary, equitable, statutory
       or otherwise.

CO-OPERATION BY PARTIES

3.3    Each party will, and it will ensure that its employees, agents and
       Affiliates will

       (a)    execute promptly upon request and at the expense of each other
              party, both during and after the termination of the Development,
              all applications, transfers, assignments, waivers and other
              documents as such other party may consider necessary or desirable
              from time to time for the purpose of

              (i)    obtaining, maintaining or vesting in, or assigning to, such
                     other party absolute title to each patent, copyright,
                     industrial design and trademark registration comprising the
                     Arising IP allocated to it under ss.3.1, and

              (ii)   applying for, prosecuting, obtaining or maintaining any
                     such patent, copyright, industrial design or trademark
                     registration,

       (b)    promptly upon request and at the expense of such other party,
              co-operate and assist such other party in a commercially
              reasonable manner in the prosecution and maintenance of each such
              application and the rights granted in respect thereof, and

       (c)    not contest the validity of any of the Arising IP allocated to
              Graftech or BPS.

JOINT ARISING IP

3.4    The parties will address Joint Arising IP issues as follows:

       (a)    all Joint Arising IP will be owned jointly by Graftech and BPS;

       (b)    regardless of inventorship, the primary responsibility for Joint
              Arising IP will be determined by the Committee after reviewing the
              respective contributions of BPS and Graftech to such Intellectual
              Property;



                                       18


       (c)    except as otherwise agreed by the parties, the party that the
              Committee determines is primarily responsible for such Joint
              Arising IP will file patent applications with respect to such
              Joint Arising IP in the name of both Graftech and BPS with the
              relevant patent offices of the United States, Canada, the European
              Community and such other jurisdictions as the parties may agree
              to. The party primarily responsible for such Joint Arising IP will
              provide at least 30 days' advance notice to the other regarding
              its intent to file patent applications in respect of such Joint
              Arising IP;

       (d)    each party will execute such documents, execute or obtain such
              assignments and waivers, and do all such other things as are
              reasonably requested by the party primarily responsible for such
              Joint Arising IP in connection with the applications for, and the
              prosecution and/or maintenance of, patent applications and patents
              in respect of the same;

       (e)    the party primarily responsible for the Joint Arising IP will be
              responsible for filing, prosecuting and maintaining such patent
              applications and patents; provided, however, that the costs
              thereof will be borne equally by BPS and Graftech;

       (f)    neither BPS nor Graftech will apply for any patent covering Joint
              Arising IP until determination as to primary responsibility
              therefor has been made by the Committee;

       (g)    if the party primarily responsible for such Joint Arising IP
              decides that it

              (i)    does not wish to file any particular patent application,

              (ii)   wishes to cease prosecution of any patent application it
                     has filed,

              (iii)  wishes to cease maintaining any patent covering such Joint
                     Arising IP in full force and effect, or

              (iv)   wishes to cease taking the administrative measures
                     necessary to maintain in full force and effect any
                     particular patent or patent application,

       it will give at least 60 days' written notice to the other of such
       decision. The other party will then, at its option, have the right to
       apply for the particular patent on such Joint Arising IP or take over
       responsibility for such patent or patent application, as applicable. In
       such case, all ownership rights will devolve to the party taking over
       responsibility for such patent or patent application; provided, however,
       that such party pays all outstanding third party costs incurred during
       the 60 day notice period related to the filing, prosecution or
       maintenance of such patent application or patent, as applicable, and the
       costs of transfer or assignment thereof;

       (h)    if either BPS or Graftech does not wish to pay its share of the
              costs of filing, prosecution or maintenance of patent applications
              or patents, as applicable, in or with respect to any particular
              jurisdiction, such party will retain its right to


                                       19


              practice the subject matter of such patent or patent application,
              but lose all rights to enforcement of such patent applications or
              patents, as the case may be, in the particular jurisdiction,

       (i)    the party that surrenders or loses its rights under ss.(g) or
              ss.(h) will execute all such documents, execute or obtain such
              assignments and waivers, and do all such other things as are
              reasonably requested by the party assuming responsibility for such
              patents or patent applications to secure the other party's rights
              in and to the same;

       (j)    except as otherwise set forth in this Agreement, for non-PEM Fuel
              Cell and non-PEM Fuel Cell Systems applications, each of BPS and
              Graftech may practice the Joint Arising IP and license the Joint
              Arising IP independently in connection with the design,
              development, manufacture and sale of Graphitic Materials and
              Graphitic Components, but only with the prior written consent of
              the other party, such consent not to be unreasonably withheld,
              conditioned or delayed, and only after such party has entered into
              an agreement with the other party concerning the payment to the
              other party of royalties in respect of such practice and/or
              license of the Joint Arising IP; provided, however, that no
              royalties will be payable in respect of Joint Arising IP
              concerning Substrates having [TEXT DELETED];

       (k)    except as otherwise set forth in this Agreement, for PEM Fuel Cell
              and PEM Fuel Cell Systems applications, each of BPS and Graftech
              may practice the Joint Arising IP and license the Joint Arising IP
              independently on a non-exclusive basis to a third party, but only
              with the prior written consent of the other party, such consent
              not to be unreasonably withheld, conditioned or delayed, and only
              after such party has entered into an agreement with the other
              party concerning the payment to the other party of royalties in
              respect of such practice and/or license of the Joint Arising IP;
              provided, however, that,

              (i)    no royalties will be payable in respect of Joint Arising IP
                     concerning Substrates having [TEXT DELETED],

              (ii)   BPS may license the Joint Arising IP to the BPS Permitted
                     Licensees for use in PEM Fuel Cells and PEM Fuel Cell
                     Systems on a royalty-free basis, without the right to
                     sublicense, and without Graftech's consent, and

              (iii)  subject to ss.2.5(c), Graftech may practice the Joint
                     Arising IP, and, subject to BPS's consent as aforesaid,
                     license the Joint Arising IP in respect of Graphitic
                     Materials and Graphitic Components for PEM Fuel Cells and
                     PEM Fuel Cell Systems on a royalty-bearing basis as
                     aforesaid after their respective Release Dates, as the case
                     may be, and

       (l)    in the case of third party infringement of Joint Arising IP, each
              of BPS and Graftech will co-operate fully with each other and
              jointly participate in all actions to terminate or prevent the
              infringement. The costs and expenses for all such actions will be
              borne equally by the parties. The party primarily responsible for
              such infringed Joint Arising IP will be obliged to initiate all
              actions to terminate


                                       20


              or prevent such infringement and will keep the other party current
              and fully apprised of the status of such actions. If the party
              primarily responsible for such Joint Arising IP does not initiate
              such actions to terminate or prevent such infringement within 90
              days after the discovery of such infringement, or the parties
              cannot, for whatever reason, co-operate with one another or
              jointly participate in such action, the other party may, by notice
              to the party primarily responsible for such Joint IP, at its own
              option and at its own expense, take appropriate action to
              terminate or prevent such infringement. Under no circumstances may
              either Graftech or BPS grant a license of the Joint Arising IP to
              an alleged third party infringer except pursuant to a settlement
              with such third party infringer and any such settlement must be
              under terms and conditions that are,

              (i)    if both Graftech and BPS have jointly participated in the
                     action, mutually agreeable to Graftech and BPS, or

              (ii)   if only one of Graftech and BPS has participated in the
                     action, as are agreeable to the party so participating.

       All awards, damages or other monetary amounts recovered pursuant to any
       action to terminate infringement of Joint Arising IP will be applied
       proportionately in accordance with the financial contributions of the
       parties towards the prevention or termination of the infringement.

GRAFTECH/BPS LICENSE

3.5    Subject to the terms and conditions of this Agreement, Graftech hereby
       grants to BPS, and BPS hereby accepts from Graftech, a non-exclusive,
       world-wide, royalty-free license to practice the Graftech Licensed

                            inclusive, of the definition of "BPS Permitted
                            Licensees" on a royalty-free basis, without a
                            further right to sublicense, without first obtaining
                            the consent of Graftech and, with respect to those
                            Persons listed in ss.(c) of the definition of "BPS
                            Permitted Licensees," so long as Graftech is able to
                            meet on a consistent basis, all of such Person's
                            requirements as to pricing, delivery, quality,
                            performance and

                                       21


                            service in respect of Graphitic Materials, BPS will
                            ensure that such Persons will purchase their
                            requirements of Graphitic Materials to produce such
                            Graphitic Components exclusively from Graftech, and

                     (B)    BPS's subcontractors (other than a subcontractor
                            having a line of business which would make it a
                            Graftech Competitor), without a further right to
                            sublicense, but only with the prior written consent
                            of Graftech, such consent not to be unreasonably
                            withheld, conditioned or delayed. In connection with
                            any sublicense to BPS's subcontractors,

                            (I)    BPS will obtain from such subcontractor a
                                   contractual obligation, for the benefit of
                                   both Graftech and BPS, which will subject the
                                   subcontractor to obligations of
                                   confidentiality at least as restrictive as
                                   those set forth in Part 4,

                            (II)   BPS will require the subcontractor, for the
                                   benefit of both Graftech and BPS, to use such
                                   sublicense solely for the production of
                                   Graphitic Components for BPS's PEM Fuel Cells
                                   and PEM Fuel Cell Systems and for no other
                                   purpose and, so long as Graftech is able to
                                   meet, on a consistent basis, BPS's
                                   requirements as to pricing, delivery,
                                   quality, performance and service in respect
                                   of Graphitic Materials, to purchase its
                                   requirements of Graphitic Materials to
                                   produce such Graphitic Components exclusively
                                   from Graftech,

                            (III)  without prejudice to any of Graftech's rights
                                   or remedies, each party will notify the other
                                   in writing of any breach by the subcontractor
                                   of the requirements described in ss.(I) and
                                   ss.(II) promptly after such party becomes
                                   aware of the same,

                            (IV)   upon BPS becoming aware of such breach, BPS
                                   will promptly, at its own expense, take such
                                   action as may be necessary to ensure
                                   compliance by the subcontractor of the
                                   foregoing requirements or, if necessary,
                                   terminate the sublicense to such
                                   subcontractor. In addition, BPS will, at
                                   Graftech's sole cost and expense, assist
                                   Graftech in pursuing such other remedies as
                                   Graftech may have against such subcontractor;

              (ii)   BPS may at any time require Graftech to, and Graftech will,
                     offer to directly grant a license in respect of any or all
                     of the Graftech Licensed Technology to any Person who is a
                     BPS Permitted Licensee on terms and


                                       22


                     conditions similar to those set forth in this ss.3.5
                      except without the right to further sublicense;

       (b)    promptly upon request by BPS, and subject to any bona fide third
              party restrictions existing as of the Effective Date prohibiting
              or limiting it from doing so, Graftech will, from time to time,
              provide to BPS all technical information, documents, plans,
              blueprints, working and other drawings, specifications, tolerances
              and other data, material and information (and sources of supply in
              lieu of any such material and information where disclosure of the
              same is limited or restricted) in the possession or under the
              control of, or made available to, Graftech, as is strictly
              necessary to enable BPS to practice the Graftech Licensed
              Technology pursuant to the Graftech/BPS License;

       (c)    subject to ss.(b), each of Graftech and BPS will promptly

              (i)    disclose to the other each Improvement to the Graftech
                     Licensed Technology made by such party during the term of
                     the Graftech/BPS License, and

              (ii)   make available to the other all technical information,
                     documents, plans, blueprints and other materials and
                     information relating to such Improvement that are strictly
                     necessary to enable the other to exercise its rights under
                     this Agreement;

       (d)    regardless of inventorship, Graftech will have the sole, exclusive
              and unrestricted right (but not the obligation) at its own cost,
              to apply for, prosecute and obtain all rights, grants,
              registrations, orders or proprietary interests of any nature,
              including, without limitation, patents, copyright, industrial
              design and trademark registrations and any other registrations or
              grants of rights that are analogous thereto in any and all
              countries throughout the world in respect of Improvements to the
              Graftech Licensed Technology. BPS will not, and it will ensure
              that none of its employees, agents or Affiliates will, in any
              manner or to any extent, either directly or indirectly commit any
              act or omission through any means that is inconsistent with the
              other party's rights under this ss.(d);

       (e)    BPS will, and it will ensure that its employees, agents and
              Affiliates, will

              (i)    execute promptly on request and at the expense of Graftech,
                     both during and after the termination of the Graftech/BPS
                     License, all applications, transfers, assignments, waivers
                     and other documents as Graftech may consider necessary or
                     desirable from time to time for the purpose of

                     (A)    obtaining, maintaining or vesting in, or assigning
                            to, Graftech, absolute title to each patent,
                            copyright, industrial design and trademark
                            registration comprising Improvements to the Graftech
                            Licensed Technology, and



                                       23


                     (B)    applying for, prosecuting, obtaining or protecting
                            any such patent, copyright, industrial design or
                            trademark registration, and

              (ii)   promptly upon request and at the expense of Graftech,
                     co-operate and assist Graftech in a commercially reasonable
                     manner in the prosecution and protection of any such
                     applications and the rights granted in respect thereof;

       (f)    Graftech will have the sole right (but not the obligation),
              including the sole right to all recoveries, to take all actions,
              including the institution of legal proceedings, which, in the
              judgement of Graftech, are reasonably calculated to terminate
              infringements of, or otherwise enforce its rights with respect to,
              the Graftech Licensed Technology. BPS will, at Graftech's cost and
              expense, fully co-operate, and not interfere, with all actions
              taken by Graftech to enforce the Graftech Licensed Technology. To
              the extent relevant to BPS, Graftech will keep BPS informed of the
              status and progress of all patent infringement actions instituted
              by Graftech;

       (g)    Graftech will have the right (but not the obligation) to defend
              all legal actions asserting the invalidity of any of the Graftech
              Licensed Technology. Graftech will promptly notify BPS of any suit
              or action involving Graftech which directly or indirectly relates
              to the validity of the Graftech Licensed Technology, and will,
              from time to time, keep BPS informed of the status of such suit or
              action. Graftech will have conduct of such defense and BPS will,
              at Graftech's cost and expense, fully co-operate, and not
              interfere, with Graftech's defense of such actions;

       (h)    subject to ss.(g), BPS will promptly notify Graftech of any suit
              or action wherein BPS is named as a party and which directly or
              indirectly relates to the use of the Graftech Licensed Technology
              or the manufacture, supply or use of any Graphitic Components
              embodying the Graftech Licensed Technology, and will, from time to
              time, keep Graftech informed of the status of such suit or action;

       (i)    except to the extent prohibited by applicable law, BPS will not
              contest the validity of the Graftech Licensed Technology;

       (j)    except as otherwise provided in ss.6.2(a)(iii)(A) and
              ss.6.2(d)(iii)(A) of this Agreement and ss.2.10(b) and
              ss.6.3(b)(iii) of the Supply Agreement, BPS will not use the
              Graftech Licensed Technology to manufacture, or permit the use of
              such technology for the manufacture of, Graphitic Materials,

       (k)    subject to earlier termination as set forth in ss.(1),
              ss.6.2(b)(ii) and ss.6.2(c)(ii), the Graftech/BPS License will
              be a perpetual license;

       (l)    the Graftech/BPS License may be terminated by Graftech, except to
              the extent that it has become irrevocable either under this
              Agreement or the Supply Agreement, without prejudice to any other
              rights it may have against BPS,



                                       24


              (i)    if BPS is the subject of an Event of Default which has, or
                     is reasonably likely to have, a material adverse effect on
                     the business of Graftech or the performance by Graftech or
                     BPS of a material term of this Agreement,

              (ii)   if BPS contests the validity of the Graftech Licensed
                     Technology, or,

              (iii)  if at any time during the term of the Graftech/BPS License,
                     BPS is in breach of its obligations under ss.2.6,

       (m)    upon termination of the Graftech/BPS License,

              (i)    subject to applicable law, Graftech will offer each Person
                     listed in ss.(a), ss.(b) and ss.(d) of the definition
                     of BPS Permitted Licensees that is not in default under its
                     sublicense with BPS (other than an Affiliate of BPS) and
                     that wishes to continue using the Graftech Licensed
                     Technology, the right to enter into a separate,
                     non-exclusive, royalty-bearing and non-sublicenseable
                     license under terms and conditions otherwise equivalent to
                     those of the Graftech/BPS License, and

              (ii)   BPS will immediately cease all practice and disclosure of,
                     and other activities pertaining to, the Graftech Licensed
                     Technology and will return all of Graftech's Confidential
                     Information in its possession or under its control to
                     Graftech;

       provided, however, that notwithstanding the foregoing, BPS will be
       entitled to practice the Graftech Licensed Technology under the
       Graftech/BPS License solely to fulfill any supply arrangements with third
       parties existing as of the date of termination, but in no event will BPS
       practice the Graftech Licensed Technology under this ss.(m) for more
       than three years after the date that the Graftech/BPS License would, but
       for this proviso, have been terminated.

BPS/GRAFTECH LICENSE

3.6    Effective upon the occurrence of a Release Date in respect of a
       particular Graphitic Component, BPS hereby grants to Graftech, and
       Graftech hereby accepts from BPS, a non-exclusive, world-wide,
       royalty-bearing license under the BPS Licensed Technology to develop,
       manufacture, make and sell to third parties such particular Graphitic
       Component embodying the BPS Licensed Technology for use in PEM Fuel Cells
       and PEM Fuel Cell Systems (the "BPS/Graftech License"), on the following
       terms and conditions:

       (a)    Graftech will pay to BPS during the term of the BPS/Graftech
              License within 60 days after the end of each calendar quarter, a
              royalty equal to the Royalty Rate on the particular Graphitic
              Component sold by Graftech or its Affiliates to third parties in
              such calendar quarter;

       (b)    all payments will be made in United States currency by wire
              transfer or cheque to such bank or account as BPS may from time to
              time specify in writing. Overdue


                                       25


              payments will bear interest at the Prime Rate plus 3% per annum,
              calculated and payable monthly, not in advance, on the last day of
              each and every month, with interest on overdue interest at the
              same rate from the due date to the date of payment;

       (c)    payments of royalties and other amounts will be free and clear of
              all taxes, duties, levies, fees or charges, except for withholding
              taxes (to the extent applicable). Any tax which Graftech is
              required to withhold with respect to royalty or other payments to
              be made to BPS will be deducted from the amount otherwise due to
              BPS;

       (d)    Graftech will deliver to BPS within 30 days after the end of each
              calendar quarter, a written report, certified by the chief
              financial officer of Graftech as being true and correct,
              describing for the applicable calendar quarter in which sales of
              Graphitic Components have occurred, the amount of royalties
              payable to BPS;

       (e)    under no circumstances will any amount payable to BPS for such
              royalties be reduced, whether by set-off, counterclaim, adjustment
              or otherwise;

       (f)    Graftech will maintain at its principal office in the United
              States, full and accurate books and records for three years in
              sufficient detail to enable royalties and other amounts payable
              pursuant to this ss.3.6 to be determined;

       (g)    upon at least 48 hours prior notice to Graftech, Graftech will
              permit BPS's certified public accountants and other external
              auditors to have full access to the books and records of Graftech
              pertaining to its activities pursuant to the BPS/Graftech License
              to verify the royalties payable and to make copies of the relevant
              books and records at BPS's expense. BPS's certified public
              accountants and other external auditors will have such access at
              all reasonable times and from time to time during normal business
              hours during the term of the BPS/Graftech License and for a period
              of three years after its expiration or termination. BPS's
              certified public accountants and other external auditors will only
              disclose the results of such audit to BPS, but not the underlying
              information. Graftech will reimburse BPS for BPS's reasonable
              costs of each such audit where such audit discloses underpayment
              by Graftech of more than 10% of the amount of royalties owed to
              BPS;

       (h)    Graftech will deliver to BPS within 120 days after the end of each
              fiscal year of Graftech,

              (i)    a written report prepared by Graftech's certified public
                     accountants, which states that, with respect to the fiscal
                     year then just completed, Graftech has paid all royalties
                     and other amounts due to BPS pursuant to this ss.3.6, and

              (ii)   a written report prepared and certified by one of
                     Graftech's senior officers, which states that, with respect
                     to the fiscal year just completed, Graftech is in
                     compliance with the royalty provisions of this ss.3.6;



                                       26


       (i)    the BPS/Graftech License is not transferable, does not include a
              "have made" right, and is not sublicensable without the prior
              written consent of BPS, except that Graftech may sublicense the
              BPS/Graftech License to subcontractors (other than to
              subcontractors having a line of business which consists of
              developing, manufacturing and/or supplying MEAs, PEM Fuel Cells or
              PEM Fuel Cell Systems), but only with the prior written consent of
              BPS, such consent not to be unreasonably withheld, conditioned or
              delayed. In connection with any sublicense to Graftech's
              subcontractors,

              (I)    Graftech will obtain from such subcontractor a contractual
                     obligation, for the benefit of both Graftech and BPS, which
                     will subject the subcontractor to obligations of
                     confidentiality at least as restrictive as those set forth
                     in Part 4,

              (II)   Graftech will require the subcontractor, for the benefit of
                     both Graftech and BPS, to use such sublicense solely for
                     the production of Graphitic Components for Graftech for PEM
                     Fuel Cells and PEM Fuel Cell Systems and for no other
                     purpose,

              (III)  without prejudice to any of BPS's rights or remedies, each
                     party will notify the other in writing of any breach by the
                     subcontractor of the requirements described in ss.(I) and
                     ss.(II) promptly after such party becomes aware of the
                     same, and

              (IV)   upon Graftech becoming aware of such breach, Graftech will
                     promptly, at its own expense, take such action as may be
                     necessary to ensure compliance by the subcontractor of the
                     foregoing requirements or, if necessary, terminate the
                     sublicense to such subcontractor. In addition, Graftech
                     will, at BPS's sole cost and expense, assist BPS in
                     pursuing such other remedies as BPS may have against such
                     subcontractor;

       (j)    promptly upon request by Graftech, and subject to any bona fide
              third party restrictions existing as of the Effective Date
              prohibiting or limiting it from doing so, BPS will, from time to
              time, provide to Graftech all technical information, documents,
              plans, blueprints and other material and information (and sources
              of supply in lieu of any such material and information where
              disclosure of the same is limited or restricted), in the
              possession or under the control of, or made available to, BPS as
              is strictly necessary to enable Graftech to practice the BPS
              Licensed Technology pursuant to the BPS/Graftech License;

       (k)    subject to ss.(j), each of Graftech and BPS will promptly



                                       27


              (i)    disclose to the other each Improvement to the BPS Licensed
                     Technology made by such party during the term of the
                     BPS/Graftech License, and

              (ii)   make available to the other all technical documents, plans,
                     information, blueprints and other materials and information
                     relating to such Improvement that are strictly necessary to
                     enable the other to exercise its rights under this
                     Agreement;

       (l)    regardless of inventorship, BPS will have the sole, exclusive and
              unrestricted right (but not the obligation) at its own cost, to
              apply for, prosecute and obtain all rights, grants, registrations,
              orders or proprietary interests of any nature, including, without
              limitation, patents, copyright, industrial design and trademark
              registrations and any other registrations or grants of rights that
              are analogous thereto in any and all countries throughout the
              world in respect of Improvements to the BPS Licensed Technology.
              Graftech will not, and it will ensure that none of its employees,
              agents or Affiliates will, in any manner or to any extent, either
              directly or indirectly commit any act or omission through any
              means that is inconsistent with the other party's rights under
              this ss.(l);

       (m)    Graftech will, and it will ensure that its employees, agents and
              Affiliates, will

              (i)    execute promptly on request and at the expense of BPS, both
                     during and after the termination of the BPS/Graftech
                     License, all applications, transfers, assignments, waivers
                     and other documents as BPS may consider necessary or
                     desirable from time to time for the purpose of

                     (A)    obtaining, maintaining or vesting in, or assigning
                            to, BPS, absolute title to each patent, copyright,
                            industrial design and trademark registration
                            comprising Improvements to the BPS Licensed
                            Technology, and

                     (B)    applying for, prosecuting, obtaining or protecting
                            any such patent, copyright, industrial design or
                            trademark registration, and

              (ii)   promptly upon request and at the expense of BPS, co-operate
                     and assist BPS in a commercially reasonable manner in the
                     prosecution and protection of any such applications and the
                     rights granted in respect thereof;

       (n)    BPS will have the sole right (but not the obligation), including
              the sole right to all recoveries, to take all actions, including
              the institution of legal proceedings, which, in the judgement of
              BPS, are reasonably calculated to terminate infringements of, or
              otherwise enforce its rights with respect to, the BPS Licensed
              Technology. Graftech will, at BPS's cost and expense, fully
              co-operate, and not interfere, with all actions taken by BPS to
              enforce the BPS Licensed Technology. To the extent relevant to
              Graftech, BPS will keep Graftech informed of the status and
              progress of all patent infringement actions instituted by BPS;



                                       28


       (o)    BPS will have the right (but not the obligation) to defend all
              legal actions asserting the invalidity of any of the BPS Licensed
              Technology. BPS will promptly notify Graftech of any suit or
              action involving BPS which directly or indirectly relates to the
              validity of the BPS Licensed Technology, and will, from time to
              time, keep Graftech informed of the status of such suit or action.
              BPS will have conduct of such defense and Graftech will fully
              co-operate, and not interfere, with BPS's defense of such actions;

       (p)    subject to ss.(o), Graftech will promptly notify BPS of any suit
              or action wherein Graftech is named as a party and which directly
              or indirectly relates to the use of the BPS Licensed Technology or
              the manufacture, supply or use of any Graphitic Component
              embodying the BPS Licensed Technology and will, from time to time,
              keep BPS informed of such suit or action;

       (q)    except to the extent prohibited by applicable law, Graftech will
              not contest the validity of the BPS Licensed Technology;

       (r)    subject to earlier termination as set forth in ss.(s),
              ss.6.2(a)(ii) and ss.6.2(d)(ii), the BPS/Graftech License will
              be a perpetual license;

       (s)    the BPS/Graftech License may be terminated by BPS, without
              prejudice to any other rights it may have against Graftech,

              (i)    if Graftech or UCAR Carbon is the subject of an Event of
                     Default which has, or is reasonably likely to have, a
                     material adverse effect on the business of BPS or the
                     performance by Graftech or BPS of a material term of this
                     Agreement, or

              (ii)   if Graftech or UCAR Carbon contests the validity of the BPS
                     Licensed Technology; or

              (iii)  if at any time during the term of the BPS/Graftech License,
                     either Graftech or UCAR Carbon is in breach of its
                     obligation under ss.2.6;

       (t)    upon termination of the BPS/Graftech License,

              (i)    Graftech will immediately cease all practice and disclosure
                     of the BPS Licensed Technology and will return all of BPS's
                     Confidential Information in its possession or under its
                     control to BPS, and

              (ii)   for greater certainty, provided that Graftech complies with
                     ss.(i), Graftech's obligations to pay royalties to BPS
                     (other than those which may have accrued up to the date of
                     termination) in connection with the BPS/Graftech License
                     will end;

       provided, however, that notwithstanding the foregoing, Graftech will be
       entitled to practice the BPS Licensed Technology under the BPS/Graftech
       License (on the royalty basis set forth herein) solely to fulfill any
       supply arrangements with third parties existing


                                       29


       as of the date of termination, but in no event will Graftech practice the
       BPS Licensed Technology under this ss.(t) for more than three years
       after the date that the BPS/Graftech License would, but for this proviso,
       have been terminated.

                     except to the extent such limitation, restriction, breach,
                     infringement, contravention or interference would not be

WARRANTIES AND COVENANTS OF BPS

                     except to the extent such limitation, restriction, breach,
                     infringement, contravention or interference would not be
                     reasonably likely to have a material adverse effect on it

                                     PART 4

                                 CONFIDENTIALITY

NON-DISCLOSURE

4.1    Each party (the "Recipient") that is the recipient of the Confidential
       Information disclosed to it by the disclosing party (the "Disclosing
       Party"), at all times during the Development Period and the Supply
       Agreement and for a period of ten years next after the expiry or earlier
       termination of such Development Period or the Supply Agreement, whichever
       is later,

       (a)    will hold, and will ensure that each of its Affiliates, directors,
              officers, employees and licensees, including sublicenses
              (collectively, the "Recipient's Agents") will hold, the
              Confidential Information of the Disclosing Party in confidence and
              in trust for the Disclosing Party,

       (b)    will not, and will ensure that the Recipient's Agents will not,
              directly or indirectly, disclose, use, reproduce or otherwise
              exploit the Confidential Information of the Disclosing Party or
              permit the same to be disclosed, used, reproduced or otherwise
              exploited, except to the extent necessary for

              (i)    the performance of the work under the SOWs,

              (ii)   the legitimate practice of the Graftech/BPS License, the
                     BPS/Graftech License and the Supply Individual Default
                     License, as the case may be,



                                       31


              (iii)  the furtherance of this Agreement; or

              (iv)   the performance of the work under the Supply Agreement;

       (c)    will only disclose the Confidential Information of the Disclosing
              Party to the Recipient's Agents

              (i)    with a definable need to know such information in
                     connection with the matters referred to in ss.(b), as the
                     case may be, and

              (ii)   who are informed of the confidential nature of such
                     information, and

       (d)    will, and will ensure that each of the Recipient's Agents will,
              protect the Confidential Information of the Disclosing Party
              against wrongful disclosure, misuse, espionage and theft.

EXCEPTIONS

4.2    This Agreement imposes no obligation on the Recipient with respect to the
       Confidential Information of the Disclosing Party,

       (a)    which is or becomes generally available to the public through no
              fault of the Recipient or the Recipient's Agents,

       (b)    which was legitimately possessed by the Recipient or the
              Recipient's Agents before its disclosure by the Disclosing Party
              to the Recipient or the Recipient's Agents, as evidenced by
              competent proof,

       (c)    which is independently obtained by the Recipient or the
              Recipient's Agents from a source which was not, at the relevant
              time, prohibited from disclosing such information to the Recipient
              or the Recipient's Agents under any legal, contractual or
              fiduciary obligation,

       (d)    which is the same as information that is developed by the
              Recipient independently without reference to the Confidential
              Information of the Disclosing Party, as evidenced by competent
              proof,

       (e)    which, subject to ss.4.3, is required to be disclosed by
              applicable law or legal process, or

       (f)    to the extent and in the manner approved by the Disclosing Party
              in writing.

LEGAL REQUIREMENT TO DISCLOSE

4.3    If the Recipient is required by applicable law, regulation or legal
       process to disclose any of the Confidential Information of the Disclosing
       Party, the Recipient will notify the Disclosing Party promptly so that
       the Disclosing Party may seek a protective order or other appropriate
       remedy or waive compliance with the terms of this Agreement. If no


                                       32


       such protective order or other remedy is obtained or the Disclosing Party
       does not waive compliance with the terms of this Agreement, the Recipient

       (a)    will furnish only that portion of the Confidential Information of
              the Disclosing Party which the Recipient is advised by counsel is
              legally required to be disclosed, and

       (b)    will exercise all reasonable efforts to obtain reliable assurances
              that confidential treatment will be accorded such Confidential
              Information.

NO SOLICITATION

4.4    No party will, during both the Development Period and the term of the
       Supply Agreement, and for a period of two years next after the expiry or
       earlier termination of the Development Period or the Supply Agreement,
       whichever is later, solicit for employment any individual who is, at the
       time of such solicitation, employed by any other party or its Affiliates
       nor will such party, directly or indirectly, induce any such individual
       to leave his or her employment. Nothing in this ss.4.4 will prevent any
       party from employing any individual that is the other party's employee so
       long as no solicitation (other than a general advertisement not directed
       to such individual) has been made to such individual by or on behalf of
       such party.

REASONABLE RESTRICTIONS

4.5    Each party agrees that the restrictions contained in this Part 4 are
       reasonable for the protection of the respective legitimate business
       interests of the parties.

PUBLICITY

4.6    The parties agree to co-operate with each other in the preparation and
       distribution of a press release regarding the execution of this
       Agreement. No public release or announcement concerning the transactions
       contemplated hereby will be issued by any party without the prior consent
       of the other parties (which consent will not be unreasonably withheld),
       except as such release or announcement may be required by law or the
       rules or regulations of any Canadian, United States or other foreign
       securities exchange, in which case the party required to make the release
       or announcement will allow the other party reasonable time to comment on
       such release or announcement in advance of such issuance.

                                     PART 5

                               DISPUTE RESOLUTION

INITIATION OF PROCESS

5.1    If at any time there is a dispute, controversy or claim (a "Dispute")
       among or between any of the parties hereto with respect to any matter
       arising out of or relating to this Agreement, then any party that wishes
       to initiate resolution of the Dispute must give


                                       33


       written notice (the "Dispute Notice") to each other party hereto, whether
       or not involved in the Dispute and to the Committee, requiring that such
       Dispute be resolved pursuant to this Part 5.

COMMITTEE INVOLVEMENT

5.2    If a Dispute Notice is given, any party involved in the Dispute may, in
       the first instance, ask the Committee forthwith to initiate discussions
       among the disputing parties with a view to settling the Dispute. A
       resolution reached by the Committee and communicated by it in writing to
       the disputing parties will be binding on the parties and will be
       implemented.

SENIOR OFFICER INVOLVEMENT

5.3    If the Dispute is not resolved between the parties thereto within 30 days
       after the date of the Dispute Notice, any party to the Dispute may ask
       the Senior Officer of each of the parties involved in the Dispute to
       forthwith initiate discussions among the disputing parties with a view to
       settling the Dispute, unless the parties agree in writing to extend such
       30-day period for resolution of the Dispute by the Committee. Once the
       Dispute is referred to the Senior Officers, the Committee will no longer
       have jurisdiction to resolve the Dispute. A resolution reached by such
       Senior Officers and communicated by them in writing to the disputing
       parties will be final and binding upon the parties and will be
       implemented.

ARBITRATION

5.4    If the Dispute is not resolved between the parties within 30 days after
       its referral to the Senior Officers, any party to the Dispute will be
       entitled to refer the Dispute to arbitration in accordance with the

                                   TERMINATION

TERMINATION

6.1    Subject to earlier termination as provided in this Part 6, the
       Development hereunder will end upon the expiry of the Development Period.
       Thereafter, unless otherwise terminated as provided herein, the
       Development will automatically be renewed for additional periods of two
       years each unless either Graftech or BPS gives written notice to the
       other parties, at least six months before the expiry of the then current
       term of the Development, to terminate the Development. Notwithstanding
       the foregoing, the Development hereunder may be terminated by either BPS
       or Graftech

       (a)    by written notice to the parties to this Agreement, if any of the
              other parties to this Agreement becomes the subject of an Event of
              Default; provided, however, that

              (i)    BPS will only be entitled to terminate the Development if
                     UCAR Carbon is the subject of an Event of Default which
                     has, or is reasonably likely to have, a material adverse
                     effect on the business of BPS or the performance by
                     Graftech or BPS of a material term of this Agreement,

              (ii)   BPS will only be entitled to terminate the Development if
                     Graftech is the subject of an Event of Default which has,
                     or is reasonably likely to have, a material adverse effect
                     on the business of BPS or the performance by Graftech or
                     BPS of a material term of this Agreement,

              (iii)  Graftech will not be entitled to terminate the Development
                     if UCAR Carbon is the subject of an Event of Default, and

              (iv)   Graftech will only be entitled to terminate the Development
                     if BPS is the subject of an Event of Default which has, or
                     is reasonably likely to have, a material adverse effect on
                     the business of Graftech or the performance by Graftech or
                     BPS of a material term of this Agreement, and,

       (b)    without cause, upon 12 months' written notice to the other, or

       (c)    by written notice to the other, if BPS and Graftech have completed
              the work required of them under the SOWs before the end of the
              Development Period and cannot agree on additional work to be done,
              or the milestones or other deliverables to be met, during the
              balance of the Development Period.



                                       35


EFFECT OF TERMINATION

6.2    In the event that

       (a)    BPS terminates the Development pursuant to ss.6.1(a),

              (i)    the rights of BPS and Graftech to independently practice
                     and license the Joint Arising IP pursuant to ss.3.4 will
                     remain intact,

              (ii)   BPS may terminate the BPS/Graftech License; provided,
                     however, that Graftech will be entitled to practice the BPS
                     Licensed Technology under the BPS/Graftech License (on the
                     royalty basis set forth in ss.3.6) solely to fulfill any
                     supply arrangements with third parties existing as of the
                     date of termination of the Development, but in no event
                     will Graftech practice the BPS Licensed Technology under
                     this ss.(ii) for more than three years after the date that
                     the BPS/Graftech License would, but for this proviso, have
                     been terminated,

              (iii)  the Graftech/BPS License will become irrevocable and
                     sublicensable by BPS without restriction, except that the
                     provisions of ss.3.5(c), (d) and (e) will not apply (other
                     than in relation to IP arising before the termination of
                     the Development pursuant to this ss.(a)), and will remain
                     royalty-free, and, so long as Graftech is able to meet, on
                     a consistent basis, BPS's requirements as to pricing,
                     delivery, quality, performance and service in respect of
                     Graphitic Materials, BPS will continue to acquire from
                     Graftech all of its requirements for Graphitic Materials
                     pursuant to the Supply Agreement; provided, however, that
                     if Graftech is no longer able to meet, on a consistent
                     basis, BPS's requirements as to pricing, delivery, quality,
                     performance and service in respect of Graphitic Materials
                     or the Supply Agreement is terminated by BPS because
                     Graftech is the subject of an Event of Default under the
                     Supply Agreement, then, subject to 6.3(b)(iii) of the
                     Supply Agreement,

                     (A)    the Graftech/BPS License will become a perpetual,
                            irrevocable, world-wide, non-exclusive,
                            royalty-bearing right and license, sublicensable by
                            BPS without restriction, to practice the Graftech IP
                            to the extent reasonably necessary to enable BPS to
                            develop, manufacture, make, have made, use and sell,

                            (I)    Graphitic Components that are the subject
                                   matter of the Development, and

                            (II)   Graphitic Materials required to make such
                                   Graphitic Components; and

                     (B)    if the parties cannot agree on such royalty within
                            30 days after the subject is first discussed, the
                            matter will be referred to the dispute resolution
                            process pursuant to Part 5.



                                       36


                            In such event, the Graftech/BPS License will include
                            the right by BPS to disclose Graftech's Confidential
                            Information to BPS's sublicensees in connection with
                            the production and use of the Graphitic Materials
                            and Graphitic Components as permitted by this
                            ss.(iii). Graftech will promptly, upon request, and
                            from time to time, transfer to, and provide BPS
                            with, all relevant technology, information, training
                            and technical assistance as may be necessary to
                            enable BPS to exercise its rights hereunder at a fee
                            that reflects no more than the reasonable cost of
                            effecting such technology transfer, training and
                            technical assistance,

              (iv)   except as otherwise permitted under ss.2.7, ss.2.9 and
                     ss.2.13 of this Agreement and ss.2.13 of the Supply
                     Agreement, Graftech will not, and it will ensure that its
                     Affiliates will not, directly or indirectly, until two
                     years after the expiry or earlier termination of the
                     Development,

                     (A)    collaborate with third parties (including Graftech's
                            Affiliates, other than its wholly-owned
                            Subsidiaries), in the research or development of
                            Graphitic Materials or Graphitic Components for PEM
                            Fuel Cells or PEM Fuel Cell Systems, or

                     (B)    license to any third party any of the Graftech IP
                            concerning Graphitic Materials or Graphitic
                            Components for use in PEM Fuel Cells or PEM Fuel
                            Cell Systems,

              (v)    subject to ss.2.13 of this Agreement and ss.2.13 of the
                     Supply Agreement, UCAR Carbon and Graftech will not, and
                     each will ensure that its Affiliates will not, directly or
                     indirectly, research, develop, manufacture, make, have
                     made, sell or supply PEM Fuel Cells and PEM Fuel Cell
                     Systems or MEAs until five years after the Development has
                     ended or the Supply Agreement has terminated, whichever is
                     later,

              (vi)   such termination will be without prejudice to any other
                     rights or remedies then available to BPS,

       (b)    Graftech terminates the Development pursuant to ss.6.1(a),

              (i)    the rights of BPS and Graftech to independently practice
                     and license the Joint Arising IP pursuant to ss.3.4 will
                     remain intact,

              (ii)   Graftech may terminate the Graftech/BPS License to the
                     extent it has not become irrevocable under this Agreement
                     or the Supply Agreement; provided, however, that to the
                     extent that the Graftech/BPS License has not become
                     irrevocable, BPS will be entitled to practice the Graftech
                     Licensed Technology under the Graftech/BPS License solely
                     to fulfill any supply arrangements with third parties
                     existing at the date of termination of the Development, but
                     in no event will BPS practice the Graftech Licensed
                     Technology under this ss.(b)(ii) for more than three years
                     after the

                     irrevocable and sublicensable without restriction, except
                     that the provisions of ss.3.6(k), (l) and (m) will not
                     apply (other than in relation to IP arising before the
                     termination of the Development pursuant to this ss.(b)),

              (iv)   except as otherwise permitted under ss.2.7, ss.2.9 and

                     Graphitic Materials, BPS will continue to acquire from
                     Graftech all of its requirements for Graphitic Materials
                     pursuant to the Supply Agreement; provided, however, that
                     if Graftech is no longer able to meet, on a consistent
                     basis, BPS's requirements as to pricing, delivery, quality,
                     performance and service in respect of Graphitic Materials
                     or the Supply Agreement is terminated by BPS because
                     Graftech is the subject of an Event of Default under the
                     Supply Agreement, then, subject to ss.6.3(b)(iii) of the
                     Supply Agreement

                     (A)    the Graftech/BPS License will become a perpetual,
                            irrevocable, world-wide, non-exclusive,
                            royalty-bearing right and license, sublicensable by
                            BPS without restriction, to practice the Graftech

                            IP to the extent reasonably necessary to enable BPS
                            to develop, manufacture, make, have made, use and
                            sell,

                                   Graphitic Components; and

                     (B)    if the parties cannot agree on such royalty within
                            30 days after the subject is first discussed, the
                            matter will be referred to arbitration pursuant to
                            Part 5.

                            In such event, the Graftech/BPS License will include
                            the right by BPS to disclose Graftech's Confidential

                            the production and use of the Graphitic Materials
                            and Graphitic Components as permitted in this
                            ss.(iii). Graftech will promptly, upon request, and

                            and technical assistance as may be necessary to
                            enable BPS to exercise its rights hereunder at a fee
                            that reflects no more than the reasonable cost of
                            effecting such technology transfer, training and
                            technical assistance,

              (i)    the rights of BPS and Graftech to independently practice
                     and license the Joint Arising IP pursuant to ss.3.4 will
                     remain intact,

      Canada and the construction, validity and performance of this Agreement
      will be governed in all respects by the laws of British Columbia, and

FORCE MAJEURE

7.10   No party will be liable to the other for default or delay in the

       partial shutdown of plant by reason of inability to obtain sufficient raw
       material or power, or any other occurrence beyond the reasonable control

SEVERABILITY

7.11   If any provision contained in this Agreement is found by any court or
       arbitrator for any reason, to be invalid, illegal or unenforceable in any
       respect in any jurisdiction,

       (a)    the validity, legality and enforceability of such provision will
              not in any way be affected or impaired thereby in any other
              jurisdiction and the validity, legality and enforceability of the
              remaining provisions contained herein will not in any way be
              affected or impaired thereby, unless in either case as a result of
              such determination this Agreement would fail in its essential
              purpose, and

       (b)    the parties will use their best efforts to substitute for any
              provision that is invalid, illegal or unenforceable in any
              jurisdiction a valid and enforceable provision which achieves to
              the greatest extent possible the economic, legal and commercial
              objectives of such invalid, illegal or unenforceable provision of
              this Agreement and, failing the agreement of the parties on such a
              substitution within 30 days after the finding of the court or
              arbitrator, either party may refer the matter for dispute
              resolution under Part 5.

COUNTERPARTS

7.12   This Agreement may be executed in counterparts or by facsimile, each of
       which will together, for all purposes, constitute one and the same
       instrument, binding on the parties,



                                       44


       and each of which will together be deemed to be an original,
       notwithstanding that all parties are not signatories to the same
       counterpart or facsimile.

NO ASSIGNMENT

7.13   No party may assign any right, benefit or interest in this Agreement
       without the written consent of each other party, such consent not to be
       unreasonably withheld, and any purported assignment without such consent
       will be void.

SURVIVAL

7.14   All rights and obligations expressly stated to continue after, or accrue
       as a result of, the termination of the Development, the Graftech/BPS
       License and/or the BPS/Graftech License are separate and distinct rights
       and obligations binding on the parties, will survive the termination of
       the Development, the Graftech/BPS License, and/or the BPS/Graftech
       License, as the case may be, and will continue in full force and effect
       and nothing herein will affect the enforceability of such provisions. For
       greater certainty, the provisions of ss.2.6, ss.2.7, ss.2.8, ss.2.9,
       ss.2.11, ss.2.13, Part 3, Part 4, Part 5, Part 6 and Part 7 which are
       expressly stated to continue, or contemplated as continuing, after the
       termination of the Development, the Graftech/BPS License, the
       BPS/Graftech License, will continue to apply after the termination of the
       Development, the Graftech/BPS License, the BPS/Graftech License, as the
       case may be. All other provisions will expire except to enforce rights
       arising prior to termination.

NO PARTNERSHIP

7.15   Nothing herein will or will be deemed to create any partnership or joint
       venture between or among the parties or to give any party any right or
       authority to act as the agent of or to pledge the credit of any other
       party.

TERMINATION OF UCAR CARBON'S OBLIGATIONS

7.16   Notwithstanding anything to the contrary in this Agreement, the rights
       and obligations of UCAR Carbon under this Agreement (other than those
       under Part 4), will terminate five years after UCAR Carbon has, directly
       or indirectly, through its Affiliates or otherwise, ceased to control
       Graftech; provided, however, that such obligations will revive if at
       anytime after it so ceases to control Graftech, UCAR Carbon directly or
       indirectly, through its Affiliates or otherwise, again controls Graftech.
       Nothing in this ss.7.16 will release Graftech from any of its obligations
       under this Agreement, each of which will continue in full force and will
       be binding on Graftech following the application of this ss.7.16. For the
       purposes hereof, UCAR Carbon will be deemed to control Graftech if

       (a)    it directly or indirectly holds a sufficient number of the voting
              rights attached to all outstanding voting securities of Graftech
              to affect materially the control of Graftech, or

       (b)    it, together with other Persons, acting jointly or in concert by
              virtue of an agreement, arrangement, commitment or understanding,
              directly or indirectly,

                                       45


      holds in total a sufficient number of the voting rights attached to all
      outstanding securities of Graftech to affect materially the control of
      Graftech.

         For purposes of this Agreement, if UCAR Carbon, alone or acting jointly
         or in concert with other Persons, directly or indirectly, holds more
         than 20% of the voting securities of Graftech, UCAR Carbon will be
         deemed, in the absence of evidence to the contrary, to control
         Graftech.

BPS/UCAR CARBON COLLABORATION AGREEMENT

7.17   Nothing in this Agreement is to be construed so as to adversely affect
       the rights of the parties under ss.3.4 and ss.3.5 of the Collaboration
       Agreement made May 3, 1999 between BPS and UCAR Carbon (with Graftech
       assuming the obligations of UCAR Carbon effective November 15, 1999), as
       may have been amended, which arose prior to the Effective Date.

REMEDIES

7.18   If any party is in default of any term or condition of this Agreement,
       each other party to this Agreement will be entitled to exercise all
       rights and remedies available to it at law, in equity or under this
       Agreement, whether or not such default constitutes an Event of Default.

                              ROYALTY DETERMINATION

            PRINCIPLES TO CONSIDER FOR THE DETERMINATION OF ROYALTIES

1.     The relative contributions of BPS and Graftech to the IP so licensed. In
       the case of Joint Arising IP, primary consideration shall be given to
       this principle in determining the royalties to be paid;

2.     the impact of the licensed IP on future sales successes of the licensee's
       product;

3.     the total market size or potential revenue or likely revenue
       realistically achievable for foreseeable products incorporating the IP so
       licensed;

4.     the Net Sales Price of the product incorporating the IP so licensed;

5.     the specific markets that are realistically addressable by products
       embodying the IP so licensed;

6.     competing processes available to the licensee and the advantages of using
       the IP over other processes;

7.     the possible duration of any competitive advantage to the licensee by
       using the IP so licensed;

8.     the development cost to the licensee of an alternative to the IP so
       licensed;

9.     opportunity costs to the licensee of assets deployed;

10.    the risks to the licensee of investment in manufacturing and
       commercialization of the licensee's products using the IP so licensed;

11.    the incremental financial investment to be made by the licensee for
       manufacturing, marketing and distribution functions;

12.    cost of intangible and intellectual capital to be employed by the
       licensee;

13.    the economic life of the product embodying the licensee's technology;

14.    the length of time required to commercialize the licensee's products; and

15.    the strength of the IP so licensed.

Royalties for licenses granted under this Agreement will be determined as soon
as practicable and to the extent possible, before the grant of the applicable
license.
