                                SALE OF MATERIALS

MATERIALS SALE

2.1 During the term of this Agreement, BPS will purchase from UCAR CARBON, and
UCAR CARBON will sell to BPS, all of BPS's requirements of the Materials in
connection with the development and manufacture of electrically conductive fuel
cell separator plates. Notwithstanding the foregoing, BPS may acquire treated
graphite flakes, expanded graphite flakes and flexible graphite from sources
other than UCAR CARBON, but solely for benchmarking purposes. BPS's obligations
under this Section 2.1 are subject to BPS qualifying the Materials according to
the quality assurance procedures as defined in BPS's quality assurance manual
and UCAR CARBON being able, on a consistent basis, to meet BPS's requirements as
to pricing, delivery, quality and service in respect of the Materials from time
to time.

SUPPLIER EVALUATION SYSTEM

2.2 In evaluating whether or not UCAR CARBON is meeting BPS's requirements as to
pricing, delivery, quality and service, BPS will utilize its Supplier Evaluation
System. BPS will provide UCAR CARBON with, and train UCAR CARBON as to its then
current criteria in respect of, its Supplier Evaluation System. No change to the
Supplier Evaluation System will be effective as to UCAR CARBON until the parties
have agreed to such change. If UCAR CARBON is unable to meet BPS's requirements
as aforesaid or any agreed changes thereto within six months after being
requested to do so BPS will be deemed to have been granted a Default License, as
defined in Section 5.2, for such time as UCAR CARBON remains in non-compliance
and BPS may acquire the Materials from one or more alternative sources without
prejudice to its rights to continue acquiring the Materials from UCAR CARBON
under this Agreement. UCAR CARBON may revoke the Default License granted
pursuant to this Section 2.2 at such time as it becomes compliant under this
section. Upon revocation of the Default License, all sublicenses granted as a
result shall be revoked by BPS and UCAR CARBON shall [TEXT DELETED] from [TEXT
DELETED] any [TEXT DELETED] that BPS may have acquired, if any, for the [TEXT
DELETED] of [TEXT DELETED] and [TEXT DELETED] BPS's related, [TEXT DELETED] and
[TEXT DELETED] under the Default License. The purchase price for the [TEXT
DELETED] shall be the value of the [TEXT DELETED] as recorded on the books of
BPS as of the date of purchase subject to normal accounting practices with
regard to
<PAGE>   7
[TEXT DELETED].

MOST FAVOURED CUSTOMER

2.3 If after termination of the Exclusive Period as defined in Section 2.9 of
the Collaboration Agreement, UCAR CARBON sells or supplies or offers to sell or
supply to another Person a like quantity of like Materials under like
circumstances at a price or on other terms that are more favourable to such
Person than the price or other terms offered to BPS, UCAR CARBON will so inform
BPS promptly. If in any [TEXT DELETED] period the price at which Materials are
sold or offered for sale to such Person is [TEXT DELETED] than the [TEXT
DELETED] or [TEXT DELETED] to BPS for a [TEXT DELETED] quantity of [TEXT
DELETED] Materials on [TEXT DELETED] terms during such period, the [TEXT
DELETED] by BPS to UCAR CARBON for the Materials will automatically be [TEXT
DELETED] to that [TEXT DELETED] price from the date on which such price was
[TEXT DELETED] to the other person. If the other [TEXT DELETED] to such other
Person are more [TEXT DELETED] than the [TEXT DELETED] to BPS, such [TEXT
DELETED] to BPS will be amended so that the more [TEXT DELETED] terms will apply
to all [TEXT DELETED] and as to all [TEXT DELETED] between BPS and UCAR CARBON.
Where applicable, the parties will make such adjustments to payments or
otherwise as may be necessary to fulfill the intent of this Section 2.3.

FIRST YEAR FORECAST AND PRICING

2.4 During the first year of this Agreement BPS agrees to buy at a minimum the
quantities set out in BPS's First Year Materials Forecast as set forth in
Schedule B and UCAR CARBON agrees to sell Materials at the prices set forth in
UCAR CARBON'S First Year Materials Pricing as set forth in Schedule C. UCAR
CARBON's pricing and delivery schedule for the first year is subject to change
if BPS makes a material change in its First Year Materials Forecast.

FUTURE FORECASTS AND PRICING

2.5 Future forecasts, pricing and production for the Materials will be dealt
with as follows:

                  (a) commencing no later than 60 days before the expiry of the
                  first year of this Agreement, and thereafter no later than the
                  end of each quarter, BPS will provide UCAR CARBON with a
                  rolling three-year forecast of its yearly requirements of the
                  Materials from UCAR CARBON, which forecast will not be binding
                  upon BPS;

                  (b) within 30 days after receipt of each Anniversary Forecast
                  (being that three-year forecast that is provided for the
                  quarter which begins on each one-year anniversary date of this
                  Agreement, i.e. the first being produced at the end of the
                  first year), UCAR CARBON will provide BPS in writing with its
                  pricing of the quantity or volume of the Materials forecast as
                  required by BPS for the first year of each Anniversary
                  Forecast and account for minor variations from quantities
                  forecast for such year together with a delivery schedule that
                  reflects such forecast;

                  (c) no later than 30 days after receipt of UCAR CARBON's quote
                  for such Materials, BPS will provide UCAR CARBON with a
                  written binding commitment to
<PAGE>   8
                  purchase a specified quantity or volume of Materials during
                  each first year of the Anniversary Forecast, which commitment
                  may vary from the forecast given by BPS for such year ("Annual
                  Commitment");

                  (d) if the quantity, timing or volume of the Materials set out
                  in the Annual Commitment is substantially different from the
                  first year of BPS's Anniversary Forecast, UCAR CARBON will no
                  longer be bound to its original price and delivery quote but
                  must, within 30 days after receipt of such Annual Commitment,
                  provide BPS with new quotes and delivery schedules that take
                  into account such difference. The parties will make the
                  appropriate adjustments to the pricing and delivery schedules
                  to reflect the new quotes and delivery schedules; and

                  (e) in addition to the foregoing, UCAR CARBON will, from time
                  to time at the request of BPS, provide BPS with firm fixed
                  quotes governing volumes of Materials for such periods of time
                  above and beyond the Annual Commitment as may, from time to
                  time, be specified by BPS.

DELIVERY OF MATERIALS

2.6 Without derogating from its obligations to supply the Materials on a timely
basis, UCAR CARBON must achieve, in any eight-week period

                  (a) during the first three months after the date of execution
                  of this Agreement, greater than an 90% on-time delivery rate
                  for the Materials with a variance from the agreed delivery
                  date of such Materials during the period of no more than two
                  days,

                  (b) subject to Section(c), after the first three months after
                  the date of execution of this Agreement, greater than a 95%
                  on-time delivery rate for the Materials with a variance from

                  the Materials of two days or such lesser period as is
                  acceptable by competitive industry standards or as agreed to
                  by the parties.

For the purposes hereof, in determining on-time delivery dates, Materials that
do not meet the agreed Specifications will be deemed not to have been delivered.

                                     PART 3

                               CONDITIONS OF SALE

SALES/PURCHASE ORDER CONDITIONS

3.1 All sales of Materials and all purchase orders issued and acknowledged under
this Agreement will be subject to the Terms and Conditions set forth below:

         (a) ACCEPTANCE

         A purchase order is not binding on BPS until accepted by UCAR CARBON.
         Acceptance of a purchase order and all terms and conditions as set out
         in this Section 3.1 will take place when (i) BPS receives UCAR CARBON's
         acknowledgement by electronic mail, fax or other agreed form, or (ii)
         UCAR CARBON delivers to BPS the materials or items ordered, whichever
         is earlier.

         (b) PRICE

         The price for the materials or items ordered will be paid by BPS in
         cleared funds to the bank nominated by UCAR CARBON within 30 days after
         the later of

                  (a)      receipt by BPS of the ordered goods, and

                  (b)      the date of the applicable invoice,
<PAGE>   10
         such payment to be made by check, credit transfer or irrevocable
         confirmed letter of credit; provided that, subject to BPS's rights
         under Section 3.1(h) and in the purchase order, BPS will only be
         obligated to pay for materials or items that are actually received by
         it. In addition, to the purchase price, BPS will pay to UCAR CARBON the
         amount of all taxes, excises or other governmental charges (except
         taxes on or measured by income) that UCAR CARBON may be required to pay
         with respect to the production, sale or transportation of any materials
         or items delivered to BPS under the purchase order.

         (c) OVERSHIPMENTS, INSTALLMENTS

         BPS will pay only for the maximum quantities ordered. Overshipments
         will be held at UCAR CARBON's risk and expense for a reasonable time
         while awaiting shipping instructions from UCAR CARBON. Return shipping
         charges for excess quantities will be at UCAR CARBON's expense. Any
         provision herein for delivery of materials or items by installment will
         not be construed as rendering the obligations of UCAR CARBON severable
         and BPS will only be obliged to pay the price of the materials or items
         included in such installment after such installment is actually
         received by BPS.

         (d) PACKING AND SHIPMENT

         Unless otherwise specified in the purchase order, if the price of the
         ordered materials or items is based on the weight thereof, such price
         must reflect the net weight of the materials or items ordered only, and
         no charges will be allowed for boxing, crating, handling damage,
         carting, drayage, storage or other packing requirements. Unless
         otherwise specified in the purchase order, all ordered materials or
         items must be securely packed in cartons, boxes or other containers,
         and marked and otherwise prepared for shipment in a manner which is

                  (i) in accordance with good commercial practice,

                  (ii) acceptable to common carriers for shipment at the lowest
                  rate for the particular materials or items, and

                  (iii) adequate to ensure safe arrival of the ordered materials
                  or items at the named destination.

         UCAR CARBON must mark all containers with necessary lifting, handling
         and shipping information, purchase order numbers, date of shipment and
         the names of the consignee and consignor, if applicable. An itemized
         packaging sheet must accompany each shipment. No partial or complete
         delivery will be permitted hereunder before the date or dates specified
         for delivery without BPS's prior written consent thereto. If the
         ordered materials or items are improperly delivered for shipment, any
         additional cost thereby incurred will be for the account of, and will
         be paid by, UCAR CARBON, and may be deducted by BPS from the payment of
         the price for such materials or items.

         (e) DELIVERY
<PAGE>   11
         Unless otherwise directed by BPS or specifically provided in the
         purchase order, the materials or items called for hereunder will be
         delivered on a FCA origin basis. The term "FCA" has the meaning
         ascribed thereto in, and is to be interpreted in accordance with, the
         Incoterms 1990 published by the International Chamber of Commerce.
         Notwithstanding the shipping terms contained in the purchase order,
         title to the materials or items and risk will remain with UCAR CARBON
         and not pass to BPS until delivery to BPS's named destination for
         importation.

         (f) WARRANTIES

         UCAR CARBON warrants, represents, covenants and agrees as follows:

                (i) the materials or items supplied pursuant to the purchase
            order will


                  (A) be in full compliance with BPS's Specifications,
                  blueprints, drawings and data,

                  (B) be in conformity with samples approved by BPS,

                  (C) not infringe any patent, copyright, trade secret, mask
                  work right, trademark or other intellectual property right of
                  any person covering the material or item itself but UCAR
                  CARBON does not warrant against infringement by reason of the
                  use of such material or item in combination with other
                  articles or material or in the practice of any process other
                  than a process for which such item has been expressly
                  manufactured by UCAR CARBON,

                  (D) be so supplied, and BPS will have title thereto, free and
                  clear of all liens, charges, encumbrances and security
                  interests;

                (ii) THERE ARE NO EXPRESS WARRANTIES BY UCAR CARBON OTHER THAN
            THOSE SPECIFIED IN THIS SECTION. NO WARRANTIES BY UCAR CARBON (OTHER
            THAN WARRANTY OF TITLE AS PROVIDED BY THE UNIFORM COMMERCIAL CODE)
            SHALL BE IMPLIED OR OTHERWISE CREATED AT LAW OR IN EQUITY,
            INCLUDING, BUT NOT LIMITED TO, WARRANTY OF MERCHANTABILITY AND
            WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE. Without limiting the
            generality of the foregoing, BPS assumes all risk and liability for
            the results obtained by the use of any products delivered hereunder
            in combination with other articles or material or in the practice of
            any process other than a process for which such item has been
            expressly manufactured by UCAR CARBON.

                (iii) BPS's receipt of any products delivered hereunder shall be
            an unqualified acceptance of, and a waiver by BPS of any and all
            claims (including claims arising under the warranties specified in
            this Section 3.1(f)) with respect to, such products unless BPS gives
            UCAR CARBON notice of claim within 150 days after such receipt or
            within ten days after BPS shall have received
<PAGE>   12

              written notice of any claim of infringement covered by clause
              (i) above,

                (iv) if any materials or items delivered hereunder do not meet
            the warranties specified herein, BPS may, at its option

              (A) require the UCAR CARBON to correct, at no cost to BPS, any
              defective or non-conforming materials or items by repair or
              replacement, or

              (B) return such defective or non-conforming materials or items at
              UCAR CARBON's expense to the UCAR CARBON and recover from the UCAR
              CARBON the purchase order price thereof, or

              (C) correct the defective or non-conforming materials or items
              itself and charge UCAR CARBON with the cost of such correction.

              The foregoing remedies are exclusive to BPS.

                            (v) No waiver by BPS of any drawing or specification
              requirement for one or more of the materials or items ordered will
              constitute a waiver of such requirements for the remaining
              materials or items to be delivered hereunder, unless specified by
              BPS in writing. The provisions of this Section 3.1(f) will not
              limit or affect the rights of BPS under Section 3.1(h).

         (g) INVOICES

         Each invoice issued as a result of the purchase order must

                  (i) be rendered separately for each delivery,

                  (ii) not cover more than one purchase order,

                  (iii) contain the purchase order number under which it is
                  issued, and

                  (iv) be rendered to the proper Accounts Payable Department of
                  BPS as set forth in the purchase order.

                  Invoice payment terms will be calculated from the date the
                  invoice is received by the proper Accounts Payable Department
                  of BPS by electronic mail, fax or other agreed form.

(h)      INSPECTION

         Materials or items purchased pursuant to the purchase order are subject
         to BPS's inspection and approval at any place BPS may reasonably
         designate. BPS may, without liability hereunder or otherwise and
         without prejudice to any other rights or remedies available to it,
         reject and refuse acceptance of any materials or items, which do not
         conform in all respects to


<PAGE>   13
                  (i) any instructions contained in the purchase order,

                  (ii) BPS's Specifications, drawings, blueprints and data, or

                  (iii) UCAR CARBON's warranties.

         With respect to any materials or items which do not so conform, BPS
         may, in BPS's sole discretion, hold such materials or items for UCAR
         CARBON's inspection at UCAR CARBON's risk upon notification to UCAR
         CARBON, or return such materials or items to UCAR CARBON at UCAR
         CARBON's expense. BPS's rejection of any materials or items subject to
         the purchase order will be without prejudice to its rights to require
         UCAR CARBON to perform its obligations in respect of the balance of the
         purchase order. Payment for any item will not be deemed to be an
         acceptance thereof.

         (i) CHANGES

         BPS may, with reasonable notice to UCAR CARBON, at any time change

                  (i) the Specifications, drawings, blue prints and data
                  concerning the ordered materials or items where such materials
                  or items are to be specifically manufactured for BPS,

                  (ii) the method of packaging, packing or shipment of the
                  ordered materials or items, and

                  (iii) the place and/or time of delivery of such materials or
                  items.

         If any such change causes an increase or decrease in the cost
         (including any unusable work in progress) or the time required for the
         delivery of the materials or items ordered, UCAR CARBON will claim an
         equitable adjustment in the price or delivery schedule, or both within
         30 days after receipt by UCAR CARBON of the requested change.

         (j) INDEMNIFICATION

         Each party will indemnify and hold the other harmless from and
         against any claim, demand, cause of action, damage, costs and
         expenses which the other might sustain or become liable for arising
         from or in connection with that party's performance or nonperformance
         hereunder. No claims of any kind, with the exception of those claims
         arising out of Section 3.1(f)(i)(C), Section 3.1(f)(i)(D), Section
         3.1(k) or Part 6 of the Agreement with respect to any material or
         item covered by this document, whether as to materials or items
         delivered or for delayed delivery or non-delivery of the material or
         item and whether or not based on negligence or warranty, shall be
         greater in aggregate amount than the purchase price of the materials
         or items in respect of which such claims are made. In no event, with
         the exception of those claims arising out of Section 3.1(f)(i)(C),
         Section 3.1(f)(i)(D), Section 3.1(k) or Part 6 of the Agreement shall
         either party be liable for special, indirect or consequential
         damages, whether or not caused by or resulting from the negligence of
         such party.
<PAGE>   14

         (k) PATENTS

         UCAR CARBON will defend, at UCAR CARBON's own expense, all suits,
         actions or proceedings in which BPS, or any of the BPS's distributees
         or dealers, or the users, lessees or customers of any of BPS's
         products, are made defendants for actual or alleged infringement of any
         copyright, trademark, trade secret, mask work right, Canadian, U.S.
         or other foreign patent or other intellectual property right resulting
         from the possession, use, sale or resale of any material or item
         purchased hereunder. If by virtue of a patent infringement suit an
         injunction is issued against BPS which prohibits or limits the use of
         any materials or items ordered or purchased hereunder or UCAR CARBON
         notifies BPS to cease use of any materials or items purchased
         hereunder, UCAR CARBON, at BPS's request, will supply BPS with
         non-infringing replacement materials or items of a similar kind,
         quality and quantity. BPS will cease use of materials or items
         purchased hereunder which are subject to an infringement action upon
         receipt of notice of such action and upon request by UCAR CARBON. UCAR
         CARBON's obligations under this Section 3.1(k) or Section 3.1(j) do not
         apply to any suits, actions or proceedings in which the actual or
         alleged infringement results from the use of such material or item in
         combination with other articles or material or in the practice of any
         process other than a process for which such item has been expressly
         manufactured by UCAR CARBON.

         (l) COMPLIANCE WITH LAW

         UCAR CARBON warrants and represents that it has complied with, and will
         continue, during the performance of its obligations hereunder, to
         comply with, all laws and conform to all requirements of each
         applicable governmental authority with respect to the supply of the
         ordered materials or items, including those concerning the packaging,
         storage, shipment and exportation of all or any part thereof, and will
         ensure that no chemical substance delivered to BPS is on the list of
         prohibited substances described in applicable environmental laws. UCAR
         CARBON will obtain all federal, provincial, state, municipal and other
         government or regulatory licenses, permits or other documents or
         permissions that are required by BPS that are incidental to the sale or
         shipment of the ordered materials or items to BPS.

         BPS warrants and represents that it has complied with, and will
         continue, during the performance of its obligations hereunder, to
         comply with, all laws and conform to all requirements of each
         applicable governmental authority with respect to the ordered materials
         or items and payment therefor and importation thereof.

         (m) NON-PUBLICITY

         Except as may be required by law or applicable governmental regulatory
         authorities, neither party will, without the prior written consent of
         the other party

                  (i) make any news release, public announcement, denial or
                  confirmation of any purchase order or its subject matter, or
<PAGE>   15

                  (ii) in any manner advertise or publish the fact that BPS has
                  placed any purchase order with UCAR CARBON.

         (n) PROPERTY

         All tooling, equipment or material of every description owned by a
         party to this Agreement (the "Owner") and furnished to the other party
         or specifically paid for by the Owner, and any replacement thereof,
         will remain the property of the Owner. Such property, and whenever
         practical, each individual item thereof, will be plainly marked or
         otherwise properly identified as the "Property of the Owner." and will
         be safely stored. The party will not substitute any property for the
         Owner's property and will not use such property except in fulfilling
         the purchase order. Such property, while in the party's custody or
         control, will be held at that party's expense, and will be insured by
         that party in an amount equal to its replacement cost with loss payable
         to Owner. Such property will be prepared for shipment and delivered in
         good condition, normal wear and tear excepted, to the Owner on a FCA
         origin basis immediately upon request by the Owner.

         (o) TERMINATION

         BPS may require UCAR CARBON to terminate work under any purchase order
         in whole or in part at any time by notice to UCAR CARBON in writing,
         whereupon UCAR CARBON will immediately stop work on the purchase order,
         or the terminated portion thereof, and notify its subcontractors to do
         likewise. Except for such termination as is caused by a default or
         delay of UCAR CARBON, UCAR CARBON will be entitled to reimbursement for
         its actual costs applicable to the termination incurred up to and
         including the date of termination. UCAR CARBON will also be entitled to
         reasonable profit on the work done before such termination at a rate
         not exceeding the rate used in establishing the original purchase
         price. The total amount of such claim will not exceed the cancelled
         commitment value of the purchase order.

         (p) TERMINATION FOR DEFAULT

         The BPS and UCAR CARBON covenant and agree as follows:

                  (i) BPS may, by written notice, terminate any purchase order
                  in whole or in part if UCAR CARBON fails

                      (A) to make delivery of the ordered materials or items or
                      to perform the services in the manner and within the time
                      specified therefor or any extension thereof by written
                      change order or amendment, or

                      (B) to replace or correct defective materials or items in
                      accordance with Section 3.1(f) and Section 3.1(h), or

                      (C) to perform any other provision of the purchase order,
                      or

                      (D) to make progress so as to endanger performance of its
<PAGE>   16
                      obligations under the purchase order;

                  (ii) if a purchase order is terminated by reason of UCAR
                  CARBON's default, UCAR CARBON will transfer title and deliver
                  to BPS, promptly at BPS's request, in the manner and to the
                  extent directed by BPS,

                      (A) any completed materials or items, and

                      (B) such particularly completed materials or items as UCAR
                      CARBON has produced or acquired for the performance of the
                      terminated part of the purchase order.

                  UCAR CARBON will protect and preserve such property in the
                  possession of UCAR CARBON. Payment for completed materials or
                  items delivered to and accepted by BPS will be in an amount
                  agreed upon by UCAR CARBON and BPS, which amount must not
                  exceed the contract price therefor; and

                  (iii) failure by BPS to enforce any of its rights under the
                  purchase order will not be deemed a waiver thereof.

         (q)      ATTORNEY'S FEES

                  If UCAR CARBON and BPS are unable to resolve any dispute
                  arising under the purchase order and any suit or other
                  judicial proceeding is instituted with reference thereto, the
                  successful party in any such suit or other judicial proceeding
                  will be paid promptly by the other party an additional amount
                  equal to the successful party's reasonable attorney's fees and
                  costs incurred.

         (r)      GENERAL

         The following general provisions will apply to all purchase orders:

                      (i) time will be of the essence hereof;

                      (ii) the purchase order is given pursuant to this
                      Agreement and will be subject to the terms of this
                      Agreement and in the event of any conflict between the
                      terms of this Agreement and the terms of the purchase
                      order, the terms of this Agreement will govern;

                      (iii) waiver by a party of any of its rights or default by
                      the other hereunder will not be deemed a waiver by such
                      party of any other right or default;

                      (iv) UCAR CARBON will not change a purchase order or ship
                      non-conforming items without first obtaining the written
                      consent of BPS;

                      (v) UCAR CARBON will, from time to time upon request by
                      BPS, do, execute, acknowledge, deliver, or cause to be
                      done, executed, acknowledged and delivered, all and every
                      such further acts, bills of sale, bills of
<PAGE>   17
                      lading, deeds, transfers and assurances as BPS may
                      reasonably request to evidence or protect BPS's ownership
                      interest in the ordered items or to carry into effect the
                      intentions of the parties as set out in this purchase
                      order.

                      (vi) UCAR CARBON will, at BPS's request, make available to
                      BPS's Affiliates those items or materials of the kind that
                      are the subject matter of the purchase order at prices
                      payable by BPS under the purchase order. UCAR CARBON may
                      but is not required, at BPS's request, to make available
                      to BPS licensees and customers those items or materials of
                      the kind that are the subject matter of the purchase order
                      at prices payable by BPS under the purchase order.

(s)      ASSIGNMENTS

         Neither party may assign any rights or obligations under a purchase
         order (including the right to receive monies due hereunder) without the
         prior written consent of the other party, and any purported assignment
         without such consent will be void. No assignment will relieve the
         assigning party from its obligations under the purchase order.

(t)      NOTICE OF LABOR DISPUTE

         Whenever an actual or potential labor dispute is delaying or threatens
         to delay the timely performance of a purchase order, the affected party
         will, as soon as practicable, notify the other party of such dispute
         and furnish all relevant details. Receipt by the other party of such
         notice will not constitute a waiver by that party of the affected
         party's obligation to meet the delivery schedule; however, such dispute
         may constitute an event of Force Majeure as governed by this Agreement.

(u)      DISPUTE RESOLUTION AND APPLICABLE LAW

         The Dispute Resolution and Applicable Law provisions set out in Parts 7
         and Section 9.8 of this Agreement shall apply to all purchase orders.

EFFECT OF PURCHASE ORDER TERMS AND CONDITIONS

3.2 The terms and conditions set forth in this Part 3 apply only as to
individual purchase orders issued and accepted in the sale of materials under
this Agreement. In no way should any term contained in Section 3.1 be construed
to give greater rights to a party or alter or amend the obligations of BPS or
UCAR CARBON under the other terms of this Agreement. While a breach of the
individual terms of a purchase order may give rise to a remedy under that
particular purchase order, as set out in this Part 3, in no event will such
breach of an individual purchase order be considered an Event of Default under
this Agreement.

REVISED PURCHASE ORDER TERMS AND CONDITIONS

3.3 BPS will notify UCAR CARBON as soon as reasonably practicable of any
proposed changes to, or substitutions of, the Terms and Conditions. No change to
the Terms and Conditions will be effective as to UCAR CARBON until the parties
have agreed to such change in writing as

<PAGE>   18
provided for in this Agreement.

                                     PART 4

                              PRICE OF THE PRODUCTS

PRICE

4.1 Subject to Section 2.3, the price payable by BPS for the Materials will be
as follows:

(a)      UCAR CARBON will provide, at no cost to BPS, other than the costs
         associated with shipping, insurance and other miscellaneous expense
         related to packing or transportation not already assumed by BPS, those
         minimal amounts of Materials that are necessary for the performance of
         the work under the Collaboration or to be incorporated into PEM Fuel
         Cells as a part of a developmental program of BPS or any of its
         Affiliates or licensees. The maximum amount of materials provided under
         this Section 4.1(a) will be determined subject to UCAR CARBON's sole
         discretion;

(b)      for all other Material supplied by UCAR CARBON and purchased by BPS the
         price will be as may be agreed upon by the parties pursuant to
         Section 2.4 and Section 2.5.

                                     PART 5

                                GRANT OF LICENSE

GRANT OF CESSATION LICENSE

5.1 Subject to Part 8 and during the term of the Exclusive Period as defined in
Section 2.9 of the Collaboration Agreement, UCAR CARBON may only elect to cease
supply of Materials to BPS if UCAR CARBON has elected to cease supplying like
Materials or like materials to all other persons for use in electrically
conductive fuel cell separator plates. If UCAR CARBON determines to make such an
election, UCAR CARBON will promptly notify BPS of its intention to cease the
supply and grant to BPS, for so long as BPS is not in material default with
regard to its obligations under this Agreement, and for so long as UCAR CARBON
does not supply such Material(s) (the license term not to exceed the term of
this Agreement, as renewed,), a worldwide, non-exclusive, right and license (the
"Cessation License") sublicensable by BPS, to use the Intellectual Property
rights of UCAR CARBON to enable BPS to make, have made, use or sell such
Material or Materials in connection with the development, manufacture, use or
sale of electrically conductive fuel cell separator plates. In any event, UCAR
CARBON agrees to continue to supply the Materials for a one-year period
following the date on which UCAR CARBON gives notice of its intent to cease to
supply the Material(s).

GRANT OF DEFAULT LICENSE

5.2 Should BPS provide notice of default to UCAR CARBON as a result of UCAR
CARBON being the subject of an Event of Default that has occurred and is
continuing to occur for reasons other than UCAR CARBON's election to cease to
supply a Material(s) as the result of a dispute between the parties as to price
or terms (regardless of whether the dispute was arbitrated), UCAR CARBON will be
deemed to have granted to BPS for the original term of this Agreement, or if
<PAGE>   20
the term has been renewed, as renewed, an irrevocable, worldwide, non-exclusive,
royalty-free and paid-up right and license (the "Default License") sublicensable
by BPS, to use the Intellectual Property rights of UCAR CARBON to enable BPS to
make, have made, use or sell the Materials in connection with the development,
manufacture or sale of electrically conductive fuel cell separator plates.

LICENSE RESTRICTIONS

5.3 Any licenses granted pursuant to this Part 5 will be in addition to, not in
substitution for, and without prejudice to, the Exclusive License or any other
license granted by UCAR CARBON to BPS under the Collaboration Agreement or
otherwise and includes the right by BPS to disclose UCAR CARBON's Confidential
Information to BPS's sublicensees only to the extent necessary and in connection
with the production, use or sale of the Materials licensed under this Part 5.
With regard to any license granted by UCAR CARBON under this Agreement, BPS
shall obtain from each of its sublicensees or other third parties from whom it
may obtain the Material(s) a contractual obligation which shall subject the
sublicensee or third party to obligations of confidentiality at least as
restrictive as that established in this Agreement and require a commitment that
the sublicensee or third party shall use the license, Materials and technology
solely for the production of Materials for BPS and for no other purpose. In
addition to all other remedies available under this Agreement, at law or in
equity, UCAR CARBON may notify BPS that BPS's sublicensee or third party appears
to be in breach of these requirements. Upon receipt of UCAR CARBON's notice, BPS
shall immediately, and at its own expense, take all necessary action to require
and insure that its sublicensee or third party complies with these requirements
including but not limited to termination of the sublicense or third party
contract, legal action to enforce the sublicense or third party contract, and
assistance to UCAR CARBON in the prosecution of any action UCAR CARBON may wish
to pursue.

TECHNOLOGY TRANSFER

5.4 UCAR CARBON will, promptly upon the grant of either a Cessation License or a
Default License, transfer to and provide BPS on a one-time basis all then
available and relevant technology, information, training and technical
assistance as may be necessary for the exploitation of the license for a
reasonable fee to be determined by the parties reflecting the reasonable cost of
effecting such technology transfer, training and technical assistance. If the
parties are unable to agree on a reasonable fee the matter will be referred to
the Dispute Resolution Procedures outlined in Part 7 of this Agreement.

FURTHER ASSURANCES FOR LICENSED MATERIALS

5.5 UCAR CARBON will execute such further assurances and other documents and
instruments and do such further and other things as may be necessary to
implement and carry out the intent of the provisions of this Part 5.

SURVIVAL OF PART 5 PROVISIONS

5.6 Notwithstanding anything in this Agreement and subject to the limitations
set out in Section
<PAGE>   21
5.3, any license granted pursuant to the provisions of this Part 5 prior to the
termination of this Agreement, will survive and continue to apply after any
early termination of this Agreement for the original term of the Agreement, or
if the term has been renewed, as renewed, and any reference in this Agreement to
termination will not affect this Part 5 unless specifically agreed to in writing
by the parties.

under circumstances upon which a license has been granted under Section 2.2 or
Part 5, UCAR CARBON will have the usual remedies available under law or equity
and may terminate all licenses extended to BPS including the Exclusive License
except with respect to that limited license required for BPS's use of the
Materials and UCAR CARBON will not be entitled to terminate this Agreement with
regard to its obligations to supply BPS with the Materials.

NO PREJUDICE

8.3 The right to terminate this Agreement will not prejudice any other right or
remedy of either party in respect of the breach concerned (if any) or any other
breach.

NO FURTHER OBLIGATIONS
<PAGE>   25

occurrence with all reasonable dispatch and, upon cessation of the occurrence,
will give prompt written notice to the other party of the same. Should an event
of Force Majeure continue for such a period of time that UCAR CARBON will not be
able to meet BPS's monthly forecast as originally established in the Annual
Commitment for the Materials, UCAR CARBON shall use reasonable commercial
efforts to obtain an alternative source for performance which may include
leasing production time, assigning a temporary license to allow a third party
(which may include BPS) to fulfill the immediate production concerns and/or
other appropriate actions.

SEVERABILITY

9.12 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,

         (a)      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 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 and 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 7.

         2.2      DELIVERS ON TIME

         Application:

         Refers to the delivery of material, or completion of services requested
         by way of purchase orders.

         Question:

         1. Does the vendor deliver ordered material or perform required
            services on time?

         Considerations:

         Early deliveries usually mean early invoices. This has an adverse
         effects on the Company's cash flow. Late deliveries have unfavorable
         effect and can results in stock-outs (back orders) which inconvenience
         the internal and external customers. Sometimes, late deliveries cause
         the Company's customers to look elsewhere for product (loss of
         opportunity for the Company).

         The delivery date is the date agreed by both the buyer and the vendor.
         The delivery date cannot be change without the approval of both the
         buyer and the vendor. To allow for shipping and handling delays, the
         Company applies a delivery grace period of two working days before or
         after the required date. If the vendor delivers the product within this
         period, the buyer considers the shipment on time. This performance
         criteria item measures the delivery of each purchase order line item.
         For example, an order for 3 pencils, 5 pens and 2 erasers would be
         three (3) line items.

         Supporting Documentation:

         Purchase Order, Invoice, Order Confirmation.

         This performance item is calculated using the following formula:

           Formula: TLI= Total Line Items

                    LLI = Late Line Items (outside the two (2) day grace period

                    (TLI-LLI)/TLI x 100 = % of One-time Deliveries

         The rating criteria will be as follows:

              % of Line Items

Supplier Price, Delivery, Quality and Service Evaluation Criteria

         2.3      DELIVER PROPER QUANTITIES

         Application:

         Refers to the delivery of material, or completion of services requested
         by way of purchase orders.

         Question:

         1.       How many incorrect quantities does the vendor ship?

         2.       Does the vendor split shipments on contracted items?

         Considerations:

         Incorrect quantities are either short shipments, over shipments or
         split shipments. All of these conditions are significant contributors
         to nonconformance costs. Short shipments and over shipments both
         require vendor contact to rectify the problem. With split shipments the
         vendor makes multiple shipments to fill the purchase order line item.
         The Company incurs additional costs in handling material. Additional
         costs are also incurred in accounting when the vendor sends a split
         shipment invoices.

         A grace quantity of five (5) percent on a under-shipment or ten (10)
         percent on a over-shipment are acceptable.

         Supporting Documentation:

         Quantity Quotation, Purchase Order, Invoice, Order Confirmation.

         This performance item is calculated using the following formula:

            Formula: TLQ= Total Line Item Quantities Received

                     ILQ= Incorrect Line Item Quantities Received

               (TLQ-ILQ)/TLQ x 100= % of Correct Line Item Quantities Received

         The rating criteria will be as follows:
