to each expert all material information, including any material changes in such
information, reasonably necessary to make the determination or reasonably
requested by the experts.

          (b) Within [****] after the [****] period referenced above, each Party
shall submit a final proposal for the relevant Phase 2 Royalty, [****] royalty,
or Added Value for MNIP with a supporting analysis prepared in writing by its
retained expert, to the other Party and to


                                      -10-

<PAGE>

the "Arbitrator." The Arbitrator shall be a person with expertise in evaluating
licenses in the photovoltaic industry, shall not have a material business
relationship with either Party and shall be reasonably acceptable to both
Parties. If the Parties have not agreed on an Arbitrator, the Parties will each
select an Arbitrator (within the stated [****] period) satisfying the above
criteria and the selected Arbitrators will select a third. In that case, the
decision of a majority of the Arbitrators will control and shall be final and
binding on both Parties.

          (c) If one Party does not submit in a timely manner a final proposal,
then the proposal of the other Party shall be used to establish the relevant
Phase 2 Royalty, [****] royalty, or Added Value for MNIP.

     4.6 Tax Authority Challenges. In the event that the tax authority
successfully challenges the adequacy or amount of the royalty or the applicable
tax provisions change, then the parties will use best reasonable efforts to
renegotiate to establish a royalty rate consistent with the requirements of
applicable law in a manner that does not adversely affect or increase the
financial burden on VentureCo.

     4.7 Royalty Calculations. Royalties shall not be due with respect to
Licensed Products for which all or part of the purchase price has been refunded
[****] of delivery (and such refunded amounts will be deducted from amounts to
which the relevant royalty rate is applied).

     4.8 Payment. To the extent applicable, VentureCo shall, within thirty (30)
days after the end of each calendar quarter during the term of this Agreement,
prepare a report summarizing the royalty payable to E pursuant to ARTICLE 4
(Consideration and Payment) including a description and basis of the calculation
thereof. VentureCo shall provide copies of such report to E, and VentureCo's
payment to E shall accompany such report.

     4.9 Currency. All payments hereunder shall be made in Euros.

     4.10 Taxes. With respect to royalties payable by VentureCo to E under this
Agreement, VentureCo shall promptly notify E of any requirement under applicable
law to deduct or withhold an amount on behalf of E on account of any tax and, if
so required under applicable law, VentureCo shall: (i) pay to the relevant
authorities the full amount required to be deducted or withheld promptly upon
determination by VentureCo that such deduction or withholding is required; and
(ii) promptly forward to E an official receipt (or certified copy), or other
documentation reasonably acceptable to E, evidencing such payment to such
authorities. To the extent that E cannot or will not be able to take a full
credit against its tax liability for the current or prior taxable years for the
full amount of the withholding tax deducted or withheld by VentureCo and is
otherwise unable to reduce or eliminate such withholding tax liability on its
own, then the Parties shall cooperate with each other and use all reasonable
efforts to reduce or eliminate such tax liability in a lawful and appropriate
manner to the extent such does not result in additional liability to VentureCo.

     4.11 Audit. Each Party shall maintain complete and accurate accounting
records, in accordance with sound accounting practices, to support and document
the royalties or payments


                                      -11-

<PAGE>

payable in connection with this Agreement. Such records shall be retained for a
period of at least three (3) years after the royalties which relate to such
records have been accrued and paid. Each Party shall, upon written request from
the other, provide access to such records to such Party for the purposes of
audit. If any such audit discloses a shortfall in payment (or an overcharge, as
the case may be) of more than [****] for any quarter, the audited Party agrees
to pay or reimburse the other Party for the expenses of such audit, and the
Parties shall reconcile payments in accordance with the results of the audit.

     4.12 Separate Agreements. MNIP shall be licensed pursuant to a separate
written agreement between the Parties (which incorporates the terms of this
Agreement as supplemented by royalties applicable to the relevant MNIP). No
license to Material New IP is granted under this Agreement; provided, however,
that MNIP listed in EXHIBIT A PART 2 shall be licensed to VentureCo (subject to
applicable royalty) immediately on commercial availability pursuant to this
Agreement.

     4.13 Prospective Basis. Any royalties or payments agreed upon by the
Parties for MNIP shall be owed on a prospective basis, and not for any products
made, used, sold, offered for sale, or imported prior to VentureCo's receipt of
the written description from E referred to in SECTION 4.1 (Material New IP -
VentureCo Request).

     4.14 Waiver. Notwithstanding the foregoing, if E discloses any Material New
IP prior to the Parties' final agreement pursuant to ARTICLE 4 (Consideration
and Payment), and VentureCo has used, incorporated or relied on such Material
New IP in a manner that cannot be readily ceased or undone without additional
cost or adversely affecting its operations, then such Material New IP shall be
deemed to be included within the scope of the license grant hereunder and E
shall waive its rights under SECTION 4.1 (Material New IP - VentureCo Request)
with respect thereto.

                                    ARTICLE 5

                          INTELLECTUAL PROPERTY RIGHTS

     5.1 Ownership.

          (a) Joint Inventions. E and VentureCo shall Jointly Own all right,
title and interest in all Intellectual Property Rights that personnel of E and
VentureCo (including third parties working on each Party's behalf) jointly
create.

               (i) Definition. For purposes of this SECTION 5.1 (Ownership),
"JOINTLY OWN" means that, subject to the terms of the licenses granted and other
provisions of this Agreement, each Party or owner thereof is free to exploit
such rights and, subject to SECTION 5.2 (Enforcement of Jointly Owned
Intellectual Property Rights), authorize others to do so, with no obligation to
account to the other Party or owner, for profits or otherwise, and each Party
hereby waives any right it may have under the laws of any country to require
such consent or accounting. In the event that either or both Parties are
pursuing enforcement pursuant to SECTION 5.2 (Enforcement


                                      -12-

<PAGE>

of Jointly Owned Intellectual Property Rights), any licensing of the respective
Jointly Owned Intellectual Property Right to the alleged Third Party infringer
shall be pursued (with the intent that the actual or alleged infringement is
regularized by appropriate license terms) by the Party or Parties pursuing the
action until the conclusion of the respective action.

               (ii) PROSECUTION AND MAINTENANCE BY VENTURECO. SUBJECT TO SECTION
5.1(C) (Expenses and Assistance), VentureCo shall have the initial right, at its
option, to control the filing for, prosecution and maintenance of any
Intellectual Property Rights that claim or disclose inventions that the Parties
Jointly Own pursuant to SECTION 5.1(A) (Joint Inventions), provided that
VentureCo shall consult with and keep E reasonably informed on matters regarding
such filing, prosecution and maintenance. In such case, subject to 5.1(C)
(Expenses and Assistance), E shall reasonably assist VentureCo, as VentureCo
reasonably requests, in VentureCo's efforts to file for, prosecute and/or
maintain the Jointly-Owned Intellectual Property Rights. For purposes of this
SECTION 5.1(A) (Joint Inventions), "PROSECUTION AND MAINTENANCE" of Intellectual
Property Rights shall be deemed to include, without limitation, responding to
office actions, payment of maintenance and annuity fees, and conduct of
interferences or oppositions, and/or requests for re examinations, reissues or
extensions of patent terms.

               (iii) By the Jointly Owning Party. To the extent that VentureCo
elects not to file, prosecute or maintain any Intellectual Property Right
jointly owned by VentureCo and E and not Q, or pay any fee related thereto, E
shall have the right, at its option, to control the filing, prosecution and/or
maintenance of any such Intellectual Property Right, provided that E shall
consult with and keep VentureCo reasonably informed of matters regarding such
filing, prosecution and maintenance. To the extent that VentureCo elects not to
file, prosecute or maintain any Intellectual Property Right Jointly Owned by
VentureCo, E and Q, or pay any fee related thereto, VentureCo shall notify Q and
E, and Q and E shall have the right, at their option, to jointly control the
filing, prosecution and/or maintenance of any such Intellectual Property Right,
provided that Q and E shall consult with and keep VentureCo reasonably informed
of matters regarding such filing, prosecution and maintenance. To the extent
that E or Q elects not to file, prosecute or maintain any such Jointly Owned
Intellectual Property Right, or pay any fee related thereto, it shall inform the
other, and such other Party shall have the right, at its option, to control the
filing, prosecution and/or maintenance of any such Intellectual Property Right,
provided that such Party shall consult with the other Party and VentureCo and
keep such parties reasonably informed of matters regarding such filing,
prosecution and maintenance.

          (b) Sole Inventions. Subject to the foregoing, each Party shall own
all right, title and interest in all Intellectual Property Rights invented or
authored solely by such Party's personnel (including third parties working on
such Party's behalf). For purposes of clarification, E retains ownership of
Intellectual Property Rights developed as of the License Effective Date and
otherwise developed outside of its cooperation with VentureCo, including without
limitation any E Technology and E Intellectual Property Rights relating to
String Ribbon Technology.


                                      -13-

<PAGE>

               (i) PROSECUTION AND MAINTENANCE; SOLE INVENTIONS RELATED TO E
TECHNOLOGY. Each Party shall have sole right, at its option, to control the
filing for, prosecution and maintenance of any Intellectual Property Rights that
claim or disclose inventions that the Party solely owns, subject to the
following. To the extent that VentureCo elects not to file, prosecute or
maintain any Intellectual Property Right relating to VentureCo's solely-owned
Intellectual Property Rights relating to the E IP provided under this Agreement,
or pay any fee related thereto, VentureCo shall notify E, and E shall have the
right, at its option, to control the filing, prosecution and/or maintenance of
any such Intellectual Property Right, and VentureCo, at E's written request,
shall transfer and assign all of its right, title and interest to such
Intellectual Property Right to E. In the event of such transfer, VentureCo
retains a world-wide, non-exclusive, non-transferable, perpetual, irrevocable,
royalty-free, sublicensable license of such transferred Intellectual Property
Rights.

               (ii) Other Prosecution and Maintenance. To the extent that
VentureCo elects not to file, prosecute or maintain any Intellectual Property
Right relating solely to VentureCo's solely-owned Intellectual Property Rights
other than Intellectual Property Rights relating to improvements to the E IP
provided under this Agreement or the Q IP provided under the Q License
Agreement, VentureCo shall notify E and Q, and E and Q shall have the right to
jointly control the filing, prosecution and/or maintenance of any such
Intellectual Property Right, and VentureCo, at E and Q's written request, shall
transfer and assign all right to such Intellectual Property Right to the joint
ownership of E and Q. In the event that either E or Q elects not to participate
in the filing, prosecution or maintenance of any Right, the other Party shall
have the right, at its option, to control the filing, prosecution and/or
maintenance of such Intellectual Property Right, and VentureCo shall, at such
Party's request, transfer and assign all of its right, title and interest to
such Party. In the event of such transfer, VentureCo retains a world-wide,
non-exclusive, non-transferable, perpetual, irrevocable, royalty-free,
sublicensable license of such transferred Intellectual Property Rights which
were originally solely owned by VentureCo.

          (c) Expenses and Assistance. To the extent a Party controls the
foregoing filing, prosecution and maintenance activities of any Jointly Owned
Intellectual Property Rights (or, pursuant to SECTION 5.1 (Ownership), another
Party's Intellectual Property Right), such controlling entity shall be
responsible for all costs and expenses incurred in connection therewith. In such
cases, subject to the foregoing, VentureCo shall reasonably assist the Jointly
Inventing Parties, as the Jointly Inventing Parties reasonably request, in
Jointly Inventing Parties' efforts to file for, prosecute and/or maintain the
Jointly Owned Intellectual Property Rights.

          (d) Employee Inventors. VentureCo shall take all necessary measures to
secure all right, title and interest in inventions that are made by its
employees under the regulations of the German Employee Inventor Law
(Arbeitnehmererfindergesetz) to the maximum extent available under applicable
law such that VentureCo may carry out its obligations of this ARTICLE 5
(Intellectual Property Rights) and the Parties may obtain and exercise their
rights to the applicable Intellectual Property Rights to the full extent and
term available under applicable law. In connection therewith, VentureCo will
comply with all applicable laws including without limitation any obligations to
employees under applicable law with respect to employee inventions.

     5.2 Enforcement of Jointly Owned Intellectual Property Rights. Each Party
shall promptly notify the other Party if it becomes aware of a possible
infringement by a Third Party of any Jointly Owned Intellectual Property Rights.
If either Party desires to take any action against such an infringing or
misappropriating Third Party, such Party shall first notify the other Party
hereto and consult with such notified Party regarding such action. If the
notified Party desires to participate in such action, the Parties shall then
jointly and cooperatively pursue such action, in which event they shall bear all
costs equally and share in any damages, royalties, license fees or other
recoveries equally, provided that either Party may at any time decide not to
participate further in such action, in which case any further costs shall be
borne by and all damages, royalties, license fees and other recoveries shall be
received by the Party which continues to pursue such action. If a Party declines
to participate in such action, the other Party shall then have the right to
pursue such action alone, and shall bear all costs of and receive all damages,
royalties, license fees and other recoveries from such action. Notwithstanding
the foregoing, if a Party declines to participate in such an action or withdraws
from such an action, such Party shall nevertheless, at the request of the other
Party, cooperate with the other Party, at the cost of the other Party and
subject to any reasonable conditions (including indemnification against
counterclaims by the third party), to the extent which may be necessary to
enable the other Party to pursue such action effectively, including without
limitation joining such action as an indispensable party.

     5.3 Third Party Licenses. To the extent that VentureCo may desire or need
rights with respect to any Intellectual Property Rights not licensed hereunder
or covered by the representations or warranties of ARTICLE 6 (Warranties),
VentureCo shall be solely responsible for obtaining such licenses and paying the
associated costs.

     5.4 Further Cooperation. Each of the Parties hereto agrees, upon the
reasonable request of the other Party, to the extent consistent with this
Agreement, to deliver to the other such records, data or other documents
reasonably requested by the other, and to take or cause to be taken all such
other actions as are reasonably necessary or desirable in order to permit the
other to obtain the full benefits of this Agreement (including the execution of
any documents required in connection therewith).

                                   ARTICLE 6

                                   WARRANTIES

     6.1 Representations and Warranties. E hereby represents and warrants to
VentureCo that:

          (a) Registered E Intellectual Property. EXHIBIT B is a complete and
accurate list of all Registered E Intellectual Property Rights. E will
supplement EXHIBIT B bi annually during the Initial Period and (with respect
MNIP used by VentureCo in the Post Termination Period) Post Termination Period,
as additional Registered E Intellectual Property Rights are applied for or
obtained.


                                      -15-

<PAGE>

          (b) Completeness. The E IP constitutes all (or a copy of all) of the
Intellectual Property owned or Licensable by E that is related to or reasonably
necessary for the conduct and operations of VentureCo as currently contemplated
to be conducted, including, without limitation, the design, development,
manufacture, use, marketing and sale of Licensed Products.

          (c) Non-Infringement. To the knowledge of E, VentureCo's use of the E
IP pursuant to this Agreement in the operation of VentureCo as it is
contemplated to be conducted following the Closing, including but not limited to
the design, development, manufacture, use, marketing and sale of Licensed
Products does not, and will not, infringe or misappropriate any Intellectual
Property Rights of any Third Party, violate any right of any Third Party
(including any right to privacy or publicity), or constitute unfair competition
or trade practices under the laws of any jurisdiction. Without limiting the
foregoing, E has not received notice from any Person claiming that such
operation or any act, product, Intellectual Property Rights, Technology or
service by E (including products, Intellectual Property Rights, Technology or
services currently under development) infringes or misappropriates any
Intellectual Property rights of any Person, violates any right of any Person or
constitutes unfair competition or trade practices under the laws of any
jurisdiction (nor does E have knowledge of any basis therefor). To the knowledge
of E, no Person is infringing or misappropriating any E IP.

          (d) Contracts. EXHIBIT C lists all contracts, licenses and agreements
under which both (1) E has been granted Intellectual Property Rights or rights
to Technology from Third Parties and (2) such rights are Licensable and
constitute E IP licensed hereunder.

     6.2 Remedy. E's sole obligation and liability for E's breach of the
representations and warranties provided in this ARTICLE 6 (Warranties) shall be
pursuant to ARTICLE 8 (Liability and Limitations of Liability) of the Master
Agreement.

     6.3 Disclaimer. EXCEPT FOR THE WARRANTIES SET FORTH IN THIS ARTICLE 6
(WARRANTIES) OR EXPRESSLY PROVIDED IN THE MASTER AGREEMENT, THE PARTIES MAKE NO
WARRANTIES, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, AND SPECIFICALLY DISCLAIM
ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NONINFRINGEMENT AND TITLE. NEITHER PARTY MAKES ANY GUARANTEES TO THE OTHER
CONCERNING THE SUCCESS OR POTENTIAL SUCCESS OR COMMERCIAL VIABILITY OF THE
ACTIVITIES CONTEMPLATED UNDER THIS AGREEMENT.

and/or Receiving Party as applicable, provided that, notwithstanding anything to
the contrary, each Party may use and distribute any such confidential or
proprietary information as reasonably required to exercise its rights under the
licenses granted pursuant to ARTICLE 2 (Rights and Licenses).

                                   ARTICLE 8

                                      TERM

     8.1 Term. This Agreement shall become effective as of the Effective Date.
The license of SECTION 2.1 (E License Grant to VentureCo) becomes effective only
as of the License Effective Date. This Agreement may be terminated only as
follows:

          (a) This Agreement shall terminate automatically and without further
action on the part of E or VentureCo in the event that the Termination Date
occurs prior to the License Effective Date.

          (b) This Agreement may terminate in the event that E and VentureCo
mutually agree in writing to terminate this Agreement (subject to the Master
Agreement).

     8.2 Special Termination Right. [****]

<PAGE>

     8.3 Effect of Termination. Upon any termination or expiration of this
Agreement, any licenses granted to VentureCo hereunder shall terminate. SECTIONS
2.2 (VentureCo License Grant to E), 2.3 (Reservation of Rights), ARTICLE 3
(Technology Transfer), ARTICLE 4 (Consideration and Payment), ARTICLE 7
(Confidential Information), SECTION 8.3 (Effect of Termination) and ARTICLE 9

                               GENERAL PROVISIONS

     9.1 Limitation of Liability.

          (a) IN NO EVENT WILL EITHER PARTY HAVE ANY LIABILITY FOR ANY SPECIAL,
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
DAMAGES FOR LOSS OF PROFITS) THAT RELATE IN ANY WAY TO THIS AGREEMENT, HOWEVER
CAUSED ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE), AND WHETHER OR NOT
SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF ANY SUCH DAMAGES.

          (b) This SECTION 9.1 (Limitation of Liability) shall not limit the
remedies that may be available to the Parties pursuant to the Master Agreement
or Concurrent Agreements. To the extent required by applicable law, nothing in
this SECTION 9.1 (Limitation of Liability) shall limit the remedies that may be
available to the Parties for fraud, bodily injury or death.

     9.2 Notices. All notices, requests and other communications to any Party

     9.4 Amendments and Waivers.

          (a) Any provision of this Agreement may be amended or waived if, but
only if, such amendment or waiver is in writing and is signed, in the case of an
amendment, by each Party to this Agreement, or in the case of a waiver, by the
Party against whom the waiver is to be effective.

          (b) No failure or delay by any Party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any or other further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

     9.5 Assignment. Other than as expressly otherwise provided herein, this
Agreement shall not be assignable or otherwise transferable by any Party hereto
without the prior written consent of the other Party hereto and the prior
written consent of Q; provided, however, that neither Party shall be obligated
to obtain the consent of the other Party under this SECTION 9.5 (Assignment)
solely by virtue of a Change of Control of such Party, and such Party shall have
the right to assign this Agreement, in its entirety including all rights and
obligations, to such Party's successor in such Change of Control. Subject to the
foregoing, the provisions of this Agreement shall be binding upon and inure to
the benefit of the Parties hereto and their respective successors and assigns.
Any assignment or transfer (including through a change of control) of this
Agreement in violation of this SECTION 9.5 (Assignment) shall be null and void.

     9.6 Entire Agreement; Severability. This Agreement, together with the
Master Agreement and Concurrent Agreements, constitutes the entire agreement
between the Parties hereto and any of such Parties' respective affiliates with
respect to the subject matter of this Agreement and supersedes all prior
communications, agreements and understandings, both oral and written, with
respect to the subject matter of this Agreement. In the event any provision of
this Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision, and the Parties agree to negotiate, in good
faith, a legal and enforceable substitute provision which most nearly effects
the Parties' intent in entering into this Agreement.

     9.7 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a Party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby or
by law or equity upon such Party, and the exercise by a Party of any one remedy
will not preclude the exercise of any other remedy. The Parties hereto agree
that irreparable damage may occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the Parties may be
entitled to seek an injunction to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in a German court, this
being in addition to any other remedy to which they are entitled at law or in
equity.

earthquake, explosion, strike, labor trouble or other industrial disturbance,
unavoidable accident, war (declared or undeclared), act of terrorism, sabotage,
