           exception of any wire transfer fee(s) which shall be borne by
           Nisshinbo. This payment is made in consideration of the License
           granted hereunder in respect of the Existing and Developing
           Technology as detailed in Article 3.

   6.2     Not more than one (1) calendar month following the end of each of the
           forty (40) quarters of the Term, Nisshinbo shall pay to Spire a ***
           royalty that is equal to *** of the Nisshinbo invoice price ("***
           Royalty") for every unit of Equipment (excluding Equipment using the
           Revolutionary Technology) that is shipped according to the negotiated
           INCOTERM to the Customer(s) or Third Party(ies) outside of Japan, or
           finally accepted by Japanese Customer(s) or Third Party(ies), during
           that quarter. The invoice price includes training, installation,
           initial spare parts, any integrated systems, advanced functions or
           other similar add-ons, but excludes any ancillary mechanisms

           what Equipment having been previously shipped was finally accepted by
           the Customer(s) and Third Party(ies) and the revenue accrued with
           each shipment/final acceptance. For this reason, notwithstanding the
           usual practice Nisshinbo uses when quoting prices to its Customer(s)
           or Third Party(ies), Nisshinbo shall provide final invoice price
           information in this report sufficiently detailed to demonstrate the
           amount of payments that Nisshinbo is required to make for that
           quarter under this Article. The *** Royalty shall be denominated in
           Japanese Yen. For avoidance of doubt, Nisshinbo shall not be required
           to pay the *** Royalty for the Equipment using the Revolutionary
           Technology. Also, the *** Royalty shall be accrued only for the Term
           (i.e. for the ten (10) years period from the Effective Date subject
           to the early termination based on Article 12) and, thereafter,
           Nisshinbo shall not be obliged to pay the *** Royalty, except that
           the Royalty payments provided for in this Article and that provided
           in Article 6.3 below shall be payable, in the final year of the Term
           (as a result of expiration or termination), on all orders received by
           either Party, whether or not shipped or finally accepted during the
           Term.

   6.3     Not more than one (1) calendar month after the end of each forty (40)
           quarters of the Term, Nisshinbo shall pay to Spire the *** Royalty

           into which Nisshinbo made more investment than that made by Spire,
           and such payment of the *** shall be made on the same calculation
           principle as stated herein. The *** under this Article 6.3 is
           denominated in the currency of the Party making the payment.

   6.4     In case that each Party has made an equivalent investment into the
           New Technology, the both Parties shall jointly own the New Technology
           and shall have full rights to use the New Technology in the Territory
           and no *** shall be due either Party. Where Nisshinbo made less
           investment into the New Technology than Spire's, Spire shall own the
           New Technology and grant Nisshinbo a license of it in accordance with
           to Article 4.1 and Nisshinbo shall pay the *** as determined by
           Article 6.3. When Spire made less investment into the New Technology
           than that made by Nisshinbo, Nisshinbo shall own the New Technology
           and grant Spire a license in accordance with to Article 4.2 and Spire
           shall pay the *** as determined by Article 6.3.

   6.5     Any Revolutionary Technology in which each Party has made an
           equivalent investment shall be jointly owned and neither Party shall
           be required to make any royalty payments as provided for in this
           Article 6 to each other. However, in any case where the investments
           made by the Parties are not equivalent, a Party making the majority
           investment shall own the Revolutionary Technology and grant a license
           to the other Party as per Articles 4.1 and 4.2, provided however
           that, in such case, the *** Royalty shall not be required and only
           the *** shall be required in accordance with Article 6.3.

   6.6     Either Party shall have the right, at any time in the first quarter
           of each year of the Term, and the first quarter after expiration or
           termination for any reason to conduct an audit of the relevant
           financial and accounting records of the other during regular business
           hours and with reasonable notice to that Party. Such audit will be
           conducted at the sole expense of the auditing Party, but with the
           reasonable cooperation of the audited Party, except that in any case
           where the auditing Party detects a discrepancy of greater than five
           (5) percent of the invoice price described by Article 6.2, then the
           audited Party shall pay all associated costs of such audit.

   6.7     Neither Party shall withhold any funds for the payment of taxes from
           any of the payments made pursuant to the provisions of this Article
           unless required under the taxation law of the U.S. or Japan, as the
           case may be. Any Party doing so as required by law shall furnish a
           clear accounting of all such withholdings, and shall assist the other
           as necessary to avoid double tax liability in their own jurisdiction
           by furnishing documentation as may be required.

   6.8     In case one Party purchases Equipment from the other Party, no
           royalty payment under Article 6 shall be due from that Party to the
           other.

ARTICLE 7. COLLABORATION AND JOINT ACTIVITIES
---------------------------------------------

SECTION A. RESEARCH AND DEVELOPMENT; TECHNOLOGY GENERATION
----------------------------------------------------------

   7.A.1.  The objective of the collaboration anticipated by this Agreement,
           to the maximum extent practical, is to advance the state of the art
           of high yield, low cost solar photovoltaic module manufacturing.
           The Parties shall fulfill this objective by the following means set
           forth in this Section:

        (a) Existing and Developing Technology Transfer (Initial):

                Within thirty (30) days from the Effective Date, Spire, being
                the source of the Technology, shall prepare and deliver in
                documentary form, all essential information regarding the
                Equipment and all other such equipment and components which
                constitute the Existing and Developing Technology, all of which
                will be furnished in the English language, and using the English
                system of measurement unless originally or already prepared in
                the metric system.

                Thereafter, Nisshinbo may dispatch as many of its technical
                staff as it sees fit (but for the purposes of administration and
                logistics, not greater than five (5) staff at one time) to
                Spire's facility for review and evaluation of the Existing and
                Developing Technology of Spire and any of Nisshinbo Existing
                Technology. All such staff of Nisshinbo shall have a competence
                in the English commensurate with the needs of a technical
                interchange, or Nisshinbo shall provide such skilled
                translators/interpreters as it deems necessary. Each Party shall
                bear its own costs to support this activity. This review and
                evaluation meeting shall last approximately two to three days.

        (b) Subsequent Technology Review Meetings:

                On approximately *** basis, the Parties shall meet to engage in
                further technology review, an event that may be referred to as
                the *** Technology Development and Planning Review Meeting. This
                meeting will primarily be conducted by and for the engineering
                staffs of both Parties, and their function shall be to make
                recommendations to the Management Team, which will make all of
                the substantive decisions in accordance with Article 2. The
                focus of each such subsequent meeting shall be for each Party to
                inform the other of every incremental improvement in the state
                of the art that the Parties have made in the preceding year, to
                share information on gains made in know-how; to discuss
                innovative ideas and to summarize progress and future plans made
                on any Program or Programs in which the Parties are jointly
                engaged. Except as stated at the beginning of this paragraph,
                the frequency, timing, and location of all such *** Development
                and Planning Review Meetings shall be decided by the Management
                Team.

        (c) Technology Development and Planning (other activities):

                The Management Team shall establish, and may modify from time to
                time, other technology development and planning events, such as,
                but not necessarily limited to, the nature and frequency of
                communications between the engineering staffs of the Parties.

<PAGE>

   7.A.2.  The Parties shall purposefully advance the state of the art in high
           yield, low cost solar photovoltaic manufacturing by conducting
           research and development Programs to promote the generation of the
           New Technology, as set forth below:

        (a) Joint Programs:

                During the *** of the Term and as needed from time to time
                thereafter, the Management Team may establish, from time to
                time, a development goal of mutual interest. The Management Team
                shall establish a budget for Joint Programs, assemble a Program
                development team, determine the criteria for success and monitor
                its progress. Such Programs are funded by a negotiated cost
                share approach between the Parties, in which the cost share may
                be equivalent or something less than equivalent. The Management
                Team shall decide on a method to ensure that all Programs costs
                are properly validated and accounted. If the costs are shared by
                the Parties on an equivalency basis, then rights in the results
                of such Joint Programs shall be perpetually jointly-owned with
                no further obligation upon either Party to make payment to the
                other, otherwise they shall treated the same way as any other
                New Technology according to Articles 4 and 6.

        (b) Individual Programs:

                The management of each Party may separately embark on Programs
                after first having proposed them to the Management Team. If the
                other Party does not conclude that the development goal is
                relevant, then the Party proposing such goal may pursue it
                individually. The ownership of all such New Technology generated
                by these individual Programs vests solely with the Party
                conducting the individual Program. In such instances, the other
                Party shall obtain a license to use any New Technology according
                to Article 4 and the royalty rate shall be determine according
                to Article 6. If after initiation of Individual Program, the
                other Party chooses to invest into a specific Individual
                Program, the Parties shall determine a level of investment that
                is mutually satisfactory and thereafter the Individual Program
                shall be converted into a Joint Program with each Party being
                considered as have made an equal investment for purposes of
                determining ownership and the application of Articles 4 and 6.

        (c) Sponsorship from Sources other than the Parties

                New Technology originating with research and development
                performed by a Party but sponsored by a third source other than
                the Parties, and where the performing Party is allowed some or
                all of the rights to the resulting technology, then a share of
                such rights may be acquired by the other Party by paying a
                portion of the valuation of such results, based upon an
                assessment made jointly by the Parties, and in accordance with
                the requirements of the agreement made with the sponsor.

   7.A.3.  The Parties may also enhance the technological base of the
           Equipment or other equipment which is or may be used in the
           manufacture of solar photovoltaic modules by acquiring licenses to
           third party technology. In such case, one Party shall act as the
           primary licensee, but shall seek to secure a sublicense for the
           other Party on terms no less favorable than those enjoyed by the
           Party acting as the licensee. The negotiation of any license under
           these circumstances shall be subject to the approval of the
           Management Team. All payments due and payable to any third party
           licensor

           would be payable by each Party in proportion to the degree to which
           either Party finds the technology from a third or outside party
           useful.

   7.A.4.  The Existing Technology, Developing Technology, New Technology, and
           Revolutionary Technology may be represented by intellectual property
           in various forms. While most of the Technology is, or likely to be in
           the form of know-how or trade secrets, to the extent any of it may be
           subject to statutory protection, i.e. an invention for which a patent
           may be obtained, it shall be the decision of the inventing Party as
           to whether a patent is obtained, and any such protection shall be
           obtained at the expense of that Party. The patent thus obtained is
           the sole property of the Party responsible for the invention, subject
           to the license and rights allocations set forth above. Patents of
           such inventions may be obtained in any number of jurisdictions by
           either Party at its expense or at the expense of both Parties. In all
           cases, anything herein to the contrary notwithstanding, the principle
           of ownership and rights to any intellectual property whether or not
           represented by a patentable invention shall rest with the degree of
           investment made by either or both Parties and not the expense made by
           one Party or the other in securing any statutory protection. The
           general principle for managing allegations of infringement by third
           parties is stated Article 9.5 below.

SECTION B. SALES AND MARKETING
------------------------------

   7.B.1.  The Parties hereto are obligated to cooperate where necessary to the
           exploit the international market for solar photovoltaic module
           manufacturing equipment and technology. Each Party shall capitalize
           its own sales and marketing efforts, which may range freely
           throughout the Territory. However, the Parties shall be guided by the
           general provisions set forth below:

<PAGE>

        (b) Use of Sales and Marketing Literature:

                During the Term, each Party shall design and publish its own
                sales and marketing literature, except that all such literature
                shall acknowledge the existence of the relationship with the
                other Party. Such notice shall be sufficiently prominent so that
                it may be noticeable with casual perusal. Such notice will
                refrain from implying the existence of a separate legal entity
                created by the Parties' relationship. Marketing literature
                published for this purpose shall be used within each Party's
                ***. The Parties shall furnish each other with a small quantity
                of their sales and marketing literature whenever created or
                revised. Sales and Marketing literature thus created and
                published shall be done at the individual expense of each Party.
                In addition to sales and marketing literature created by each
                Party for use in their ***, the Parties shall jointly prepare
                and publish sales and marketing literature that presents the
                experience of both Parties and of the Consortium in a unified
                and mutually advantageous format. The Parties may use this sales
                and marketing literature for all global, neutral and joint
                marketing endeavors. The cost of such sales and marketing
                literature shall be shared by the Parties based on the volume of
                literature that each Party uses.

SECTION C. EQUIPMENT MANUFACTURING
----------------------------------

   7.C.1.  During the Term, each Party intends to manufacture the Equipment for
           contract awards within its ***. Additionally, the

                                       12
<PAGE>

           Parties may manufacture units of Equipment for each other. Under such
           circumstances, each Party shall not offer such Equipment to the other
           at any price other than that which they would ordinarily consider to
           be its most favorable price, i.e. that which would be the lowest
           possible commercial price for which they sell Equipment to a third
           party (but not below such price). No royalty payments from either
           Party to the other as provided for in Article 6 shall be due and
           payable in this case.

           During the Term, each Party shall provide after sales service and
           repair to all Equipment sold under contract awards that it executed,
           and each Party is responsible for supporting its standard Equipment
           warranty. The foregoing notwithstanding, either Party may request the
           other Party for assistance and/or support for its after sales service
           requirements, the cost of which the requesting Party shall bear.

   SECTION D. MANAGEMENT TEAM

   7.D.1.  The Management Team shall consist of two management persons appointed
           by Spire and two management persons appointed by Nisshinbo. The
           Management Team shall provide oversight to the Parties' Activities
           and act in a manner consistent with the interests of the Consortium.
           The Management Team will not be required to provide a decision-making
           function on ordinary matters under consideration by each Party
           individually, but exists for the purpose of providing a unified
           strategic business approach for the Consortium, and act, when
           necessary, as the final authority for decisions affecting the
           Consortium's business endeavors.

   7.D.2.  In the event that the two Parties cannot otherwise agree, sales
           inquiries, purchase and sales agreements, purchase orders and other
           transactions with prospective and current Customers *** which Party
           shall supply the prospective or current customer with its stated
           requirements.


ARTICLE 8. NATURE OF RELATIONSHIP
---------------------------------

   8.1     This Agreement shall not be construed as creating any new legal
           entity based upon the joint activities of the Parties. The Parties
           and all of their activities remain legally separate from one another.

   8.2     This Agreement does not authorize either Party to act as an agent or
           representative of the other. No such authority shall be implied by
           this Agreement, and to the extent any such authority is extended from
           one Party to the other during the Term it shall be done by a separate
           express instrument to that effect.

   8.3     By virtue of the warranties made in Article 9 either Party may retain
           any existing Third Party relationship as of the Effective Date
           (beyond those existing between vendor and customer, and except as
           where specified in Article 9 in the solar photovoltaic module
           manufacturing equipment industry.

   8.4     During the Term, neither Party may enter into any relationship
           (regardless of how it is made) that will place that Party in breach
           of the warranties in Article 9.

   8.5     During the Term, the Parties may elect to convert this Consortium
           into an incorporated joint venture. The Parties shall accomplish this
           by mutual consent, and the failure of one Party or the other to agree
           to negotiate the terms of such joint venture shall not be a
           permissible cause for termination of this Agreement nor for any
           request for arbitration. Should the Parties agree to the conversion
           of this Agreement into a joint venture, this document shall remain in
           force until the date the joint venture is established.


ARTICLE 9. WARRANTIES AND REPRESENTATIONS

           below:

                                       15
<PAGE>

        (a)  for material breach. The Parties shall regard egregious and/or
             repeated failure of a Party to fulfill its obligations under this
             Agreement to constitute a material breach, but not any event of
             FORCE MAJEURE so long as such event has not ended. Any failure to
             perform the obligations under this Agreement shall be resolved by
             the Management Term. In any instance where one Party has materially
             breached this Agreement, the other Party shall allow the breaching
             Party a period of sixty (60) days beginning from the date of the
             notice of termination to affect a cure of such breach. If at the
             end of the sixty-day period, the breaching Party has not affected a
             wholly satisfactory cure, the other Party may allow, at its
             discretion, the breaching Party the final thirty (30) day period to
             affect a cure satisfactory to the other Party. Any Party breaching
             this Agreement without having affected a cure shall be obligated to
             pay the appropriate termination fee as provided for in Article
             12.2.

        (b)  for bankruptcy. In any instance where an involuntary bankruptcy
             proceeding is filed against either Party, the Party subject to such
             proceeding is required to inform the other within ten (10) days of
             having been received notice of such filing. The other Party may
             terminate upon thirty (30) days notice if such involuntary
             proceeding is not dismissed within ninety (90) days from the date
             it was filed.

        (c)  for convenience. Either Party may terminate this Agreement for its
             convenience. The Party terminating this Agreement must give not
             less than one hundred eighty (180) days notice of such termination
             to the other Party.

   12.2    Except as provided in Article 12.3 below, where this Agreement is
           actually terminated by either Party based on Article 12.1 (a) or (c),
           a penalty shall be paid by the breaching Party to the other Party (in
           case of Article 12.1 (a)), or by the terminating Party to the other
           Party (in case of Article 12.1 (c)), in accordance with the schedule
           below, such that if:

        (a)  Nisshinbo is the breaching or terminating Party, it shall pay to
             Spire a penalty equal to *** for each year remaining in the Term,
             with amounts for fractional years prorated. Such penalty shall be
             at no time less than the equivalent of the sum of the payments paid
             by Nisshinbo to Spire during the two year period immediately past
             under Articles 6.2 and 6.3.

        (b)  Spire is the breaching or terminating Party; it shall pay to
             Nisshinbo a penalty equal to *** for each year remaining in the
             Term, with amounts for fractional years prorated.

   12.3    Should either Party dissolve the business unit engaged in the
           activities contemplated under this Agreement, or be forced out of
           business due to a FORCE MAJEURE circumstance as defined in Article
           16.9 below or otherwise cease to engage in this the solar
           photovoltaic module manufacturing equipment business or all business
           activities, no penalty shall be due and owing to the other Party
           under this Article, unless the Party should re-enter the subject
           matter business with a period of five (5) years from having exited
           it, in which case that Party shall pay the other the original penalty
           as provided for hereunder plus a premium equal to *** of its value.

ARTICLE 16. GENERAL PROVISIONS
------------------------------

   16.1    This Agreement with its Exhibits contains the entire agreement and
           understanding with regard to the subject matter hereof and supercedes
           any and all prior understandings, correspondence and agreements, oral
           and written, between the Parties.

   16.2    No change, amendment or modification to or of this Agreement shall

           both Parties.

   16.3    The titles of each of the Articles to this Agreement shall not be

           When the FORCE MAJeure is of such an extent that (i) the objectives
           of this Agreement are substantially impaired, or (ii) that a Party's
           performance is impaired for more than three (3) months, then the
           other Party may terminate this Agreement with immediate effect
           without any liability to either Party hereunder.

     WHEREAS, Spire and Company have represented to each other that each owns,
may own or is interested in receiving Proprietary Information (as defined below)
pertaining to:

     Conception, development, design and manufacture of complex,
     electro-mechanical equipment and devices in general, and equipment and
     devices used in the photovoltaic module fabrication process in particular;
     data and information on costs, pricing and related subjects.

     WHEREAS, Spire and Company intend to exchange Proprietary Information for
the following purpose(s):

     of development and maintenance of business relations.

     NOW, THEREFORE, for the good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereby agree as
follows:

1.   DEFINITION

     For purposes of this Agreement, "Proprietary Information" means data,
reports, specifications, designs, prototypes, test results, trade secrets,
processes, patentable inventions, plans or other business, financial or
technical information in written, electronic magnetic or oral form (i) which is
known only to the disclosing party, (or to others to whom the disclosing party
has voluntarily disclosed it subject to restrictions similar to those set forth
in this Agreement); (ii) as to which the disclosing party has taken reasonable
precautions against disclosure; and (iii) which has been clearly labeled by the
disclosing party as "confidential," "proprietary," "secret" or other term or
similar import. Orally disclosed Proprietary Information shall retain its
character as Proprietary Information so long as the proprietary, protected
nature of the disclosed information is conveyed to the recipient: (a) orally at
the same meeting or in the same conversation as the Proprietary Information is
discussed and in writing within thirty (30) days of the original disclosure; or
(b) in writing only, within ten (10) days of the original disclosure, in which
case the recipient shall not be held liable for any disclosure of the
Proprietary Information prior to it being so labeled.

2.   OBLIGATION TO PROTECT PROPRIETARY INFORMATION

     (a) Each party agrees that if it is a recipient under this Agreement, it
will not publish or otherwise disclose Proprietary Information received from the
disclosing party to any third party or to any person employed by the recipient
other than those who have a "need to know" in order to evaluate Proprietary
Information and make the decisions contemplated by this Agreement. Any employee,
consultant or other agent to whom a recipient party discloses Proprietary
Information received for a disclosing party as provided in this Agreement, shall
be subject to confidentiality obligations to such recipient party covering the
Proprietary Information to at least the same extent as the recipient party is
obligated by this Agreement. Each recipient party agrees to exercise reasonable
care to protect the disclosing party's Proprietary Information and shall utilize
the same procedures and systems to protect such Proprietary Information as it
utilizes to protect its own Proprietary Information and other proprietary data.

     (b) Each party agrees to use Proprietary Information received from the
other party only for the purposes described in this Agreement.

     (c) Immediately upon the request of the disclosing party, the recipient
shall return to the disclosing party any of the disclosing party's Proprietary
Information so requested without retaining any copies thereof. Upon termination
of the relationship or discussions contemplated by this Agreement, all
Proprietary Information shall be returned by the recipient to the disclosing
party without retaining any copies thereof.

                                       28
<PAGE>

     (d) Unless otherwise stated in writing signed by the parties, a recipient's
obligation to protect Proprietary Information shall continue for five (5) years
from disclosure.

     (e) Company further agrees that it will at no time during the five (5)
years from the date written above use its access to Spire employees as an
opportunity to solicit their employment elsewhere on Company's or any other
party's behalf and for any purpose.

3.   LIMITATIONS ON THE PARTIES' OBLIGATIONS

     No obligation to protect Proprietary Information shall exist under this
Agreement with respect to any information which: (a) at the time of disclosure
is in the public domain, (b) enters the public domain through no act or failure
to act by the recipient, (c) comes into the possession of the recipient from a
third party without obligation on the recipient to maintain it in confidence, or
(d) at the time of disclosure to the recipient was already known to the
recipient as evidenced by appropriate documentation.

4.   EFFECT OF AGREEMENT

     All Proprietary Information remains the property of the disclosing party at
all times. This Agreement does not constitute the promise or intention of either
party to buy, or sell or market any products or services or to enter into any
other type of arrangement or agreement. This Agreement does not constitute or
imply the grant of any license or permission to use any intellectual property or
Proprietary Information except to the limited extent and for the limited
purposes set forth herein.

5.   MISCELLANEOUS

     Any failure by either party to enforce its rights under this Agreement in
any one instance shall not constitute a waiver of those rights in any other
instance. The Parties acknowledge that a breach of this Agreement by a recipient
may result in irreparable harm to the disclosing party not easily measured in
monetary damages alone. Therefore, in addition to all other remedies available
at law, the parties consent to the imposition of equitable remedies including
injunctive relief without the necessity of proof of actual damages. This
Agreement shall be governed and construed under the laws of the Commonwealth of
Massachusetts.

6.      TERM

     The term of this Agreement shall be three (3) years from the date written
above, except as to the obligations set forth in paragraph 2.
