                           and its Affiliates and computing Net Sales of goods
                           by Licensor to Licensee and its Affiliates for use in
                           the manufacture of Licensed Products) the invoice

                           others.

                           In computing Net Sales of Licensed Products by
                           Licensee and its Affiliates, the following provisions
                           also apply:

                           (A)      With respect to sales of Licensed Products
                                    made to any purchaser which does not deal at
                                    arm's length with the seller, or if Licensed
                                    Products are made available by Licensor or
                                    its Affiliates to any third party under
                                    circumstances in which no sale takes place,
                                    Net Sales shall be computed using the then
                                    current highest published list price of
                                    Licensee and its Affiliates for Licensed
                                    Products offered for sale or, if no such
                                    list price has been published, the average
                                    of the published list prices of equivalent
                                    products offered by other manufacturers
                                    (including Licensor).

                           (B)      If Licensed Products are sold in the form of
                                    combination products containing one or more
                                    products or parts in addition to the
                                    Licensed Products, Net Sales for such
                                    combination products shall be calculated by
                                    multiplying actual Net Sales of such
                                    combination products by the fraction
                                    A/(A+B), where A is the invoice price of the
                                    Licensed Product, if sold separately by
                                    Licensee or its Affiliate, and B is the
                                    invoice price of any other product or part
                                    in the combination, if sold separately by
                                    Licensee or its Affiliate.

                           (C)      If the other products or parts in the
                                    combination are not sold separately by
                                    Licensee, Net Sales for such combination
                                    products shall be calculated by multiplying
                                    actual Net Sales of such combination
                                    products by the fraction A/C where A is the
                                    invoice price of the Licensed Product if
                                    sold

                                     Page 2



                                    separately by Licensee or its Affiliate and
                                    C is the invoice price of the combination
                                    product.

                           (D)      If neither the Licensed Products nor the
                                    combination product is sold separately by
                                    Licensee or its Affiliate, Net Sales for
                                    such combination products shall be
                                    calculated by multiplying actual Net Sales
                                    of such combination products by the fraction
                                    A/C where A is Licensee's and its
                                    Affiliates' total actual cost of the
                                    Licensed Products and C is Licensee's and
                                    its Affiliates' total actual cost of the
                                    combination product.

                  (h)      "Patent Rights" means, insofar as the same apply
                           within the Territory with respect to the Licensed

                           by Licensor to Licensee concurrently with the
                           execution of this Agreement, and all patents issuing
                           from such patent applications including all

                           rights (including, by way of example, patents, patent

                           Agreement. "Controlled" as used with respect to
                           Subject Rights means at least the degree of control
                           needed to grant licenses of the scope and content

                           have made, use or sell Licensed Products outside the
                           Territory or to use the Licensed Processes at any
                           location outside the Territory. Without limiting the
                           foregoing, the license does not include the right to
                           (and Licensee agrees that it will not) sell
                           substrates with epitaxial layers made using the
                           Licensed Processes nor use such substrates for

                           any purpose other than the manufacture of Licensed
                           Products.

                  (c)      Licensor and Licensee may from time to time agree in
                           writing, on a customer by customer basis, that
                           Licensee may sell Licensed Products to specific
                           customers outside the Territory on a nonexclusive
                           basis.  Licensor and Licensee may from time to time
                           agree in writing, on a country-by-country basis with
                           respect to countries outside the Territory, that
                           Licensee may make and use the Licensed Products and
                           Licensed Processes within such country on a
                           nonexclusive basis.  Actions of Licensee in
                           accordance with the terms and conditions of a written
                           agreement which references this paragraph and is
                           signed on behalf of the parties shall be considered
                           licensed pursuant to this Section 2.1.  Nothing in
                           this Agreement shall be construed to obligate the
                           parties to enter into any agreement under this
                           paragraph.

                  (d)      Any sales of Licensed Products which Licensee is
                           authorized to make to a customer outside the
                           Territory pursuant to Section 2.1(c) may be made by
                           Licensee or its Affiliates directly or through
                           Sumitomo Corporation and its Affiliates.

         2.2.     Duration.

                  The license granted under Section 2.1 shall commence on the
                  Effective Date and, except as otherwise provided in Section
                  8.3, shall continue until the later of the expiration of the
                  last-to-expire patent included in the Licensed Rights or for
                  so long as any of the Subject Technology is used in the
                  manufacture of the Licensed Products.

         2.3.     Exclusivity.

                  (a)      The license granted under Section 2.1 shall be
                           exclusive within the Territory during the term of
                           this Agreement as provided in this Section 2.3.

                  (b)      Licensor may sell Licensed Products to the Licensee
                           or its Affiliates or pursuant to the Distributorship
                           Agreement dated June 22, 1995 among Licensor,
                           Licensee and the other parties named therein, as such
                           agreement may be amended from time to time, but
                           Licensor:

                           (i)      shall not otherwise retain any right to sell
                                    the Licensed Products within the Territory
                                    during the term of this Agreement; and

                           (ii)     shall not retain any right to make or use
                                    the Licensed Products within the Territory
                                    during the term of this Agreement, or to use
                                    the Licensed Processes within the Territory
                                    during the term of this Agreement for the
                                    manufacture of the Licensed Products.

                  (c)       Nothing in this Agreement shall prevent Licensor:

                           (i)      after the expiration or termination of this
                                    Agreement, from making, having made, using
                                    or selling Licensed Products within the
                                    Territory or using Licensed Processes within
                                    the Territory,

                           (ii)     at any time, from making, having made, using
                                    or selling Licensed Products outside the
                                    Territory or using Licensed Processes
                                    outside the

                           (iii)    at any time, from using Licensed Processes
                                    within the Territory for the manufacture of
                                    products other than LED products.

                  (d)      The exclusivity conferred hereby shall mean, except
                           as otherwise provided in this Section 2.3, that:

                           (i)      Licensor warrants that it has not previously
                                    granted any license to any third party, with
                                    respect to Subject Technology owned by

                                    Agreement, or to use the Licensed Processes
                                    within the Territory during the term of this
                                    Agreement for the manufacture of Licensed

         2.4.     Sublicenses.

                  (a)      The rights licensed under Section 2.1 may be
                           exercised by Licensee, or by any Affiliate of
                           Licensee pursuant to a sublicense granted to the
                           Affiliate in accordance with this Section 2.4,
                           provided the Affiliate first agrees in writing with
                           Licensor to hold all Confidential Information of
                           Licensor in confidence under terms of this Agreement
                           and otherwise to comply with all of the obligations
                           imposed on Licensee under this Agreement.

                  (b)      Any sublicense shall be subject to the terms and
                           conditions of this Agreement, and any act or omission
                           by the sublicensee which would constitute a breach of
                           this Agreement if done or omitted by Licensee shall
                           be considered a breach of this Agreement by Licensee.
                           Without limiting the foregoing, Licensee shall in all
                           events remain responsible for the reporting and
                           payment to Licensor of all royalties due with respect
                           to sales by sublicensees.

                  (c)      Except as permitted by this Section 2.4, the rights
                           licensed under Section 2.1 may not be sublicensed
                           without the Licensor's prior consent, which the
                           Licensor may

                                     Page 5



                           withhold in its sole discretion, and may not be
                           transferred except as part of an assignment of this
                           Agreement made in accordance with Article 11.

3.        TECHNOLOGY TRANSFER

         3.1.     Delivery of Documentation.

                  Licensor will provide Licensee documentation describing the
                  Subject Technology in such reasonable detail and to such an
                  extent as is adequate for competent technical personnel
                  experienced in epitaxial deposition and device fabrication
                  generally to understand the Subject Technology and to
                  manufacture the Licensed Products. The documentation will
                  disclose all matters which, at the time of delivery, are known
                  or believed by Licensor's technical personnel, responsible for
                  its own manufacture of Licensed Products, to have a material
                  effect on the yield or repeatability of the Licensed Processes
                  and which are not obvious to competent technical personnel
                  experienced in epitaxial deposition and device fabrication
                  generally. The documentation to be delivered pursuant to this
                  Section 3.1 is listed in Schedule 3 and will be delivered in
                  accordance with the schedule set forth in Schedule 3.

         3.2.     Technical Assistance.

                  Licensor shall provide technical assistance to Licensee in
                  connection with the manufacture of the Licensed Products in
                  the manner and subject to the terms and conditions set forth
                  in Schedule 3.

         3.3.     Targeted Process Yields.

                  In providing documentation and technical assistance required
                  by this Article 3, and subject to the limitations on the
                  commitment of the time of Licensor's personnel set forth in
                  Schedule 3, Licensor will endeavor to assist Licensee in
                  achieving on average, measured during one (1) calendar month,
                  a die yield per wafer which is not less than
                  *********************** of the Licensor's average die yield
                  per wafer in manufacturing Licensed Products during the
                  preceding six (6) calendar months. It is understood that
                  Licensor makes no warranty and provides no other assurance
                  that such yields can in fact be achieved. Licensor shall
                  permit Licensee's duly authorized representative, reasonably
                  acceptable to Licensor, to examine Licensor's records of its
                  die yield per wafer at all reasonable business hours to the
                  extent and insofar as it is necessary to verify the accuracy
                  of the average die yield per wafer reported by Licensor to
                  Licensee for purposes of this paragraph.

         3.4.     Restricted Information.

                  Nothing in this Article 3 shall be construed to require
                  Licensor to grant Licensee access to, or otherwise to disclose
                  to Licensee, any information held by Licensor under
                  restrictions on use or disclosure which preclude disclosure to
                  third parties.

4.        LICENSE FEE AND ROYALTIES

         4.1.      License Issue Fee.

                  (a)      In consideration of the license conferred by Section
                           2.1, Licensee shall pay Licensor a license issue fee
                           of Two Million Seven Hundred Thousand Dollars


                                     Page 6



                           ($2,700,000) (U.S).

                  (b)      The license issue fee shall be due and payable in
                           installments in the amounts and on the dates
                           specified in Schedule 4.

                  (c)      The license issue fee shall be considered fully
                           earned at the Effective Date of this Agreement.
                           Thereafter Licensee's obligation to pay the issue fee
                           shall be unconditional, not subject to set-off or
                           deduction of any kind, and shall survive any
                           termination or expiration of this Agreement.

         4.2.      Royalties.

                  (a)      Licensee shall pay to Licensor, for all sales of
                           Licensed Products made by Licensee and its
                           sublicensees during the period specified in Schedule
                           4, a royalty equal to the percentage specified in
                           Schedule 4 multiplied times the difference between
                           (i) the Net Sales of Licensed Products by Licensee
                           and its sublicensees minus (ii) the Net Sales to
                           Licensee and its sublicensees of materials supplied
                           by Licensor for use in the manufacture of Licensed
                           Products.

                  (b)      Upon payment in full of the license issue fee due
                           under Section 4.1, and all royalties accrued during
                           the period specified in Schedule 4, the license
                           conferred by Section 2.1 shall be fully paid such
                           that no further royalties shall be due with respect
                           to sales of the Licensed Products thereafter.

                  (c)      Royalties shall accrue on sales of Licensed Products
                           made during the period specified in Schedule 4
                           notwithstanding any earlier termination of this
                           Agreement. This Article 4 shall survive any
                           termination of this Agreement so as to cover sales of
                           Licensed Products made thereafter on which royalties
                           are due under the terms hereof. Survival of this
                           Article 4 shall not be construed as conferring any
                           additional license, whether express or implied,
                           respect to the Licensed Rights.

                  (d)      In the event that, prior to expiration of the royalty
                           period specified in Schedule 4, all patents included
                           in the Licensed Rights shall have expired or been
                           finally adjudged by a court of competent jurisdiction
                           to be invalid, and no patent applications included in
                           the Licensed Rights remain pending, the parties shall
                           in good faith negotiate an appropriate adjustment in
                           the royalty rate applicable to sales of Licensed
                           Products made thereafter.

                           the Licensed Products.  Licensee shall render a
                           statement within thirty (30) days after the end of
                           each calendar quarter setting forth the quantity of

                           thereon.  The royalties due shall be paid in U.S.
                           Dollars simultaneously with the sending of the
                           statement.  The amount of royalty first calculated in
                           Japanese Yen shall be converted into U.S. Dollars at
                           the T/T selling price rate quoted by Tokyo-Mitsubishi
                           Bank as of five (5) working days prior to the date of
                           remittance.

                  (b)      Licensee shall permit Licensor's duly authorized
                           representative, reasonably acceptable to Licensee, to
                           examine the above-mentioned books of account

                                     Page 7




                           relating to the Licensed Products at all reasonable
                           business hours to the extent and insofar as it is
                           necessary to verify the accuracy of the statement
                           rendered by the Licensee pursuant to Section 4.3(a)
                           above.

                  (c)      Licensor shall have the right to designate a firm of
                           certified public accountants, reasonably acceptable
                           to Licensee, to audit the above-mentioned books of
                           account relating to the Licensed Products in order to
                           ascertain the accuracy of the statement rendered by
                           the Licensee pursuant to Section 4.3(a) above.  The
                           expense of the audit shall be Licensor's unless the
                           audit shall demonstrate a discrepancy (in Licensee's
                           favor) greater than five percent (5%) between the
                           royalties reported and paid and those which were
                           actually due, in which event the audit expenses shall
                           be borne by Licensee.

         4.4.     Payment.

                  (a)      All payments under this Article 4 shall be made in
                           U.S. dollars by wire transfer deposited to Licensor's
                           credit at such U.S. bank as Licensor may from time to
                           time designate.

                  (b)      All taxes levied in accordance with the tax laws of
                           Japan,  or any other country in which Licensed
                           Products are sold under this Agreement, on any
                           payments to be made by the Licensee to the Licensor
                           hereunder (not including any taxes on Licensee's net
                           income) shall be borne by the Licensor.  When,
                           pursuant to such tax laws, the Licensee is required
                           to withhold such taxes and pay them to the taxing
                           authority on the Licensor's behalf, the Licensee is
                           hereby authorized to withhold and deduct such taxes
                           from the applicable payments to the Licensor,
                           provided that the Licensee shall furnish the Licensor
                           with the tax receipts or other evidence showing the
                           payment of such taxes.

                  (c)      Any amounts to be paid under this Agreement which are
                           not paid at the later of the date due or the
                           expiration of any stated grace period shall accrue
                           interest from the date due until the date paid at a
                           rate equal to one percent (1%) plus the prime rate as

                  If either party or its Affiliates develops or acquires any
                  Covered Improvements prior to the expiration or termination of
                  this Agreement, it will promptly disclose such Covered
                  Improvements to the other party, and the other party and its
                  Affiliates shall be deemed to have an irrevocable,
                  nonexclusive license to practice the same for the purpose of
                  making, using and selling Licensed Products. The license shall
                  not include the right to grant sublicenses. The license shall
                  be royalty-free, except as otherwise provided in this
                  Agreement with respect to Licensed Products sold by Licensee
                  and its Affiliates. It is understood that neither party makes

                  improvements will in fact be made.

         5.2.      ************************.

                  (a)       Licensor and Licensee each agree that it will not,
                  and will not allow its Affiliates,

                           thereafter, to assert against the other party or its
                           Affiliates any Subject Rights on account of the
                           manufacture, use or sale by such other party or its

                           acquired from third parties in accordance with
                           Section 5.2(e).

                  (b)      Nothing in this Agreement shall obligate either party
                           to transfer or disclose to the other information
                           concerning the design, manufacture or other aspects

                           manufacture of the Licensed Products.

                  (c)      Except as otherwise provided in Section 5.2(d), this
                           Section 5.2 constitutes a covenant to refrain from
                           asserting certain rights and not the grant of a
                           license, and nothing herein shall encumber the
                           Subject Rights of either party or bind any assignee
                           thereof.

                  (d)      In the event that either party or its Affiliates are
                           joint owners with any third party of Subject Rights
                           which the third party owner is entitled assert
                           contrary to Section 5.2(a), then the party to this
                           Agreement which jointly owns such rights shall grant
                           the other party and its Affiliates a royalty-free,

                           ownership permit such licensing.  The license shall
                           be effective during the term of this Agreement, shall
                           not include the right to grant sublicenses, and shall
                           grant the right to practice such Subject Rights to

                           manufactured by Licensor or its Affiliates or
                           acquired from third parties in accordance with
                           Section 5.2(e).

                  (e)      If a third party supplier (other than an Affiliate of
                           Licensee) extends a bona fide written offer to supply
                           silicon carbide substrates to Licensee or its
                           Affiliates for use in manufacturing

                           as described in this Section 5.2, Licensee and its
                           Affiliates may purchase the quantity offered by such
                           supplier pursuant to the offer, provided that (i)
                           such third party substrates meet or exceed the
                           specifications of the corresponding product offered
                           by Licensor; (ii) Licensee gives Licensor written
                           notice of the terms of the third party offer and
                           Licensor does not, within thirty (30) days
                           thereafter, agree to supply such quantity at the
                           price and in accordance with the delivery schedule
                           and other terms and conditions stated in the third

                           by Licensee and its Affiliates from third party
                           suppliers during each period of twelve months

                           price or specifications, or Licensor is unable to

                           Licensee's request representatives of the parties
                           shall meet and in good faith discuss and endeavor to

                           5.2(e) or other action to address Licensee's
                           reasonable concerns.

         5.3.      Right of First Refusal on Wafer Manufacturing License.

                  (a)      Licensor agrees that it will not, during the first
                           three (3) years of the term of this Agreement, grant
                           to any third party (other than an Affiliate of
                           Licensor) any license to manufacture silicon carbide
                           substrates (including but not limited to bulk growth
                           of silicon carbide, any polish, wafering, wafer
                           refinishing or other pre-epitaxial process) within
                           the Territory except in compliance with this Section
                           5.3(a).  Licensor will first offer the license to
                           Licensee in writing.  If Licensee does not accept the
                           offer by written notice of acceptance received by
                           Licensor within ninety (90) days after Licensee
                           receives the offer, Licensor may at any time
                           thereafter grant the license to any third party
                           provided that the terms of the license are no more
                           favorable than those previously offered to Licensee.

                  (b)      Each party agrees that it will not, during the first
                           three (3) years of the term of this Agreement, grant
                           to any third party (other than its Affiliates), or
                           permit its Affiliates to grant to any third party
                           (other than another Affiliate), any license to make,
                           use, sell or otherwise practice any Other LED
                           Technology (as defined below) within the Territory in
                           the case of Licensor, or outside the Territory in the
                           case of Licensee, except in compliance with this
                           Section 5.3(b).  The party desiring to grant such
                           license (the "offering party") shall first offer the
                           license to the other party in writing (the "other
                           party").  If the other party does not accept the
                           offer by written notice of acceptance received by the
                           offering party within thirty (30) days after the
                           other party received the offer, the offering party
                           may at any time thereafter grant the license to any
                           third party, provided that the terms of the license
                           are no more favorable than those previously offered
                           to the other party.  For purposes of this Section
                           5.3(b), the term "Other LED Technology" means:

                           (i)      improvements to blue LED die which are not
                                    within the definition of Licensed Products
                                    and Covered Improvements;

6.        INFRINGEMENTS

         6.1.      Infringement by Third Parties.

                  (a)      Each party shall advise the other promptly upon
                           becoming aware of any infringement by a third party
                           of any Patent Right within the Territory.  The
                           Licensor shall, within reasonable limits and at its
                           own discretion, promptly take such action (legal or
                           otherwise) as is required to restrain such
                           infringement.  The Licensee shall cooperate fully
                           with the Licensor, at the latter's reasonable
                           expense, in the Licensor's effort to restrain such
                           infringement.  The Licensee may be represented by
                           counsel of its own selection at its own expense in
                           any suit or proceeding brought to restrain such
                           infringement, but the Licensor shall have the right
                           to control the suit or proceeding and obtain all
                           benefits in the recoveries resulting from such suit
                           or proceeding, whether by judgment, award, decree or
                           settlement.

                  (b)      If, within sixty (60) days of the Licensee's giving
                           notice to the Licensor of any third party
                           infringement within the Territory, the Licensor fails
                           to institute an

                                     Page 11




                           infringement action or proceeding that the Licensee
                           reasonably feels is required, the Licensee shall have
                           the right at its own discretion at any time
                           thereafter to institute an action or proceeding in
                           the Territory for infringement of any of the claim or
                           claims of the Patent Rights. It is agreed that in
                           such event the Licensee or its sublicensee may
                           institute any such suit in its own name or in the
                           names of each party to this Agreement (subject, in
                           the case of Licensor, to its prior written consent
                           which shall not be unreasonably withheld) and the
                           Licensee shall bear the expense of any such suit or
                           suits and shall obtain all of the benefits in the
                           recoveries resulting therefrom, whether by judgment,
                           award, decree or settlement. Should the Licensee
                           bring any such suit or proceeding, the Licensor shall
                           cooperate in all reasonable ways with the Licensee in
                           such suit or proceeding at the Licensee's expense.

                  (c)      Both the parties hereto may mutually agree to bear
                           equally the costs and expenses in any such suit or
                           proceeding. If the parties so agree, they shall share
                           equally in any and all benefits in the recovery
                           whether by judgment, award, decree or settlement.

         6.2.      Infringement of Third Party Rights.

                  (a)      If any third party claims or institutes legal action
                           against the Licensee alleging that the manufacture,
                           sale, or use of the Licensed Products under the
                           license conferred by this Agreement infringes patent
                           rights of such third party, the Licensee shall
                           promptly notify the Licensor in writing of such claim
                           or action.

                  (b)      Upon such notice, the Licensor and the Licensee shall
                           consult and discuss whether it would be reasonable to
                           bring or defend any suit or proceeding concerning
                           infringement of a third party's patent in the
                           Territory or whether other measures should be
                           undertaken in order to avoid the time and expense
                           inherent  in any such suit or proceeding.  Both
                           parties shall have the right to participate, at their
                           own expense and through counsel of their own
                           choosing, in any settlement discussions relating to,
                           or the defense of, any claim of infringement lodged
                           as a consequence of the Licensee's marketing of
                           Licensed Products within the Territory under the
                           license conferred by this Agreement.

                  (c)      Should the Licensee or its sublicensees be required
                           either by judgment, award or decree, or by settlement
                           consented to by the Licensor (which consent shall not
                           be unreasonably withheld) to make royalty payments to
                           a third party (other than an Affiliate of Licensee)
                           as a consequence of any claim that the Licensee's or
                           its sublicensees' marketing of the Licensed Products
                           in a country within the Territory, under the license
                           conferred by this Agreement, infringes patent rights
                           of such third party, it is agreed that the running
                           royalties due and payable to the Licensor under this
                           Agreement for the manufacture, use and sale of the
                           Licensed Products in such country shall be reduced by
                           an amount equal to that which the Licensee or its
                           sublicensees are required to pay said third party;
                           provided, that (i) Licensee promptly notifies
                           Licensor in writing of any such claim of
                           infringement, (ii) Licensee cooperates fully with the
                           Licensor, at the Licensee's expense, in the defense
                           thereof, and (iii) Licensee allows the Licensor to
                           control the defense to such claim and any settlement

                           Information of the disclosing party, it shall
                           promptly notify the disclosing party and to the
                           extent permitted by the circumstances allow the
                           disclosing party a reasonable time to oppose such
                           process.

                  (b)      Each party shall protect Confidential Information of
                           the other by using the same degree of care, but not
                           less than a reasonable degree of care, to prevent
                           unauthorized disclosure or use as that party uses to
                           protect its own confidential information of like
                           nature.  Within each party and their respective
                           Affiliates, Confidential Information shall be
                           disclosed only to employees to whom disclosure is
                           reasonably necessary to the exercise of the licenses
                           granted hereunder or the performance of this
                           Agreement. Each party shall limit the number of
                           copies made of any item of received Confidential
                           Information.

                  (c)      Each party shall appropriately notify each employee,

                           hereof.

         13.3.    Relationship of the Parties.

                  The relationship of the parties under this Agreement is
                  intended to be that of independent contractors. Nothing herein
                  shall be construed to create any partnership, joint venture or
                  agency relationship of any kind. Neither party has any
                  authority under this Agreement to assume or create any
                  obligations on behalf of or in the name of the other party or

                  undertaking with any third party.

                  Any disputes or claims arising from this Agreement or its
                  breach shall be submitted to and resolved exclusively by
                  arbitration conducted in accordance with the Rules of
                  Conciliation and Arbitration of the International Chamber of
                  Commerce. The arbitration shall be conducted by three (3)
                  arbitrators appointed in accordance with such rules. The place
                  of arbitration shall be in San Francisco, California. An award
                  rendered in the arbitration shall be final and binding upon
                  the parties and judgment may be entered thereon in any court
                  of competent jurisdiction. The arbitrators shall apply the
                  laws specified in this Agreement in determining the rights,
                  obligations and liabilities of the parties and shall not have
                  the power to alter, modify, amend, add to or subtract from any
                  term or provision of this Agreement nor to rule upon or grant
                  any extension, renewal or continuance of this Agreement, nor
                  to award damages or other remedies expressly prohibited by
                  this Agreement, nor to grant injunctive relief, including
                  interim relief, of any nature, notwithstanding any contrary
                  provisions of the Rules of Conciliation and Arbitration
                  specified above. If, under applicable law, this arbitration
                  provision is not enforceable as to a particular claim brought
                  by one party against the other, then legal proceedings
                  involving only that claim may be instituted solely in the
                  United States District Court of the Eastern District of North
                  Carolina or, if such court may not exercise jurisdiction, a
                  court of the State of North Carolina. For all purposes of this
                  Agreement, all parties hereby irrevocably consent to the
                  jurisdiction of such court and waive any defense based on
                  improper or inconvenient venue or lack of personal
                  jurisdiction.

         13.5.    Severability.

                  If any provision of this Agreement is found invalid or
                  unenforceable, the remaining provisions will be given effect
                  as if the invalid or unenforceable provision were not a part
                  of this Agreement.

                                     Page 17




         13.6.    Amendments; Waiver.

                  This Agreement may not be amended except in a writing signed
                  by the authorized representatives of both parties. No waiver
                  of any provision of this Agreement shall be effective unless
                  made in writing and signed by the party sought to be charged
                  therewith. The failure of either party to enforce any
                  provision of this Agreement shall not constitute or be
                  construed as a waiver of such provision or of the right to
                  enforce it at a later time.

         13.7.    Enforcement Costs.

                  The prevailing party in any arbitration or judicial action
                  brought to enforce the provisions of this Agreement shall be
                  entitled to recover its costs and expenses, including
                  reasonable attorneys' fees, incurred in filing and prosecuting
                  or defending such action.

         13.8.    Governing Law.

                  This Agreement shall be governed by and construed in
                  accordance with the laws of the State of North Carolina,
                  without regard to conflicts of laws principles.

         13.9.    Construction.

                  The captions contained in this Agreement are for reference
                  only and shall not be used in its construction or
                  interpretation. The provisions of this Agreement shall be
                  construed and interpreted fairly to both parties without
                  regard to which party drafted the same.

         13.10.   United Nations Convention.

                  The United Nations Convention on Contracts for the
                  International Sale of Goods shall not apply to this Agreement.

         13.11.   Fair Trade Commission Action.

                  In the event that the Fair Trade Commission of Japan should
                  advise or recommend modification, amendment and/or deletion of
                  any terms and conditions of this Agreement pursuant to the
                  "Law relating to Prohibition of Private Monopoly and Methods
                  of Preserving Fair Trade" of Japan, Licensee shall immediately
                  inform Licensor in writing of such advice or recommendation
                  and the parties hereto agree to negotiate in good faith to
                  modify, amend, and/or delete the terms and conditions
                  concerned in this Agreement in accordance with the said advice
                  or recommendation. In the event that the parties are unable to
                  agree in writing within thirty (30) days after Licensee
                  informs Licensor of the action of the Fair Trade Commission,
                  either of the parties hereto may upon written notice to the
                  other terminate this Agreement without incurring any
                  liability.

         13.12.   Entire Agreement.

                  This Agreement sets forth the entire agreement between the
                  parties with respect to the subject matter hereof and
