                           CONSIDERATION AND PAYMENT

     4.1 Royalty. Subject to exceptions in this Agreement, VentureCo shall pay
royalties to E for the use of MNIP. The royalty shall be based on two main
elements: the success of the relevant MNIP in achieving Cost Savings and the
success of that MNIP in achieving Added Value, [****]. For the sake of
commercial simplicity the product of the two base rate elements shall be
converted into a combined royalty rate, at intervals specified in relevant
Sections below. The detailed rules of royalty calculation, including exceptions,
follow below.

     The royalty and other fees (if any) (collectively "ROYALTY") payable for
the use of MNIP shall be [****] generally determined as set forth below. The
royalty payment obligations commence (with respect to Licensed Products Sold
incorporating that MNIP) the later of (1) January 1 2007, and (2) the date when
VentureCo first Sells Licensed Products that incorporate that MNIP.

     For purposes of this Agreement, Thin Ribbon Technology (as described in
Exhibit A, part [2] item [2], will be deemed MNIP.

          (a) Royalty Rate in General. The royalty rate applicable hereunder
("Royalty Rate") shall be as set forth in the following table shall continue
until [****] ("Royalty Renewal Date").

          (b) Annual Adjustments. The Royalty Rate may be adjusted on annual
basis as follows. While Annual Adjustments may be made as set forth below, in
making such adjustments, the Parties shall give deference to the above rates,
and any adjustments shall made primarily to account for changes after the above
rates were established. At least [****] days in advance of the [****] of the
Royalty Renewal Date, the Parties shall agree upon a new market based Royalty
Rate that shall be applicable for the next [****] year period commencing on the
[****] of the Royalty Renewal Date. In the event that VentureCo and E cannot
agree on the Royalty Rate applicable to such next [****] year period, or at the
election of either VentureCo and E, the Royalty Rate for currently used MNIP
shall be determined in accordance with Section 4.1(f) (Alternative Royalty Rate
Calculation Based on MNIP).

          (c) Exceptional Adjustments. The Royalty Rate may be modified before
the annual adjustment of Section 4.1(b) (Annual Adjustments) at the request of
either party as set forth below in Section 4.1(c)(i) (Performance) or Section
4.1(c)(ii) (Compared to Conventional Silicon).

               (i) Performance. In the event that the performance of the MNIP
used by VentureCo differs substantially from the performance anticipated at the
time the Royalty Rate was determined in accordance with 4.1(b) (Annual
Adjustments), the Royalty Rate may be modified in accordance with this Section
4.1(c) (Exceptional Adjustments) to reflect this unexpected performance. For a
difference in performance to merit a change of Royalty Rate under this section
4.1 (c) (Exceptional Adjustments), the change would comprise [****].

               (ii) Compared to Conventional Silicon. [****].

               (iii) New Royalty Rate. In the event that a change in Royalty
Rate is requested and the change in Royalty Rate is merited based on Section
4.1(b)(i) (Performance) or Section 4.1(b)(ii) (Compared to Conventional
Silicon), Parties agree to negotiate in good faith to determine the new
applicable Royalty Rate based on the actual and then anticipated performance of
the MNIP or change in Costs/Value of the Licensed Products respectively. The
Party asserting that the Royalty Rate should be changed shall have the burden of
proof of showing that a change should be made. In the event that the Parties do
not agree on the new applicable Royalty Rate merited based on Section 4.1(b)(i)
(Performance) or Section 4.1(b)(ii) (Compared to Conventional Silicon), the
Royalty Rate shall be determined based on the expected and actual performance of
the MNIP in accordance with Section 4.2 (Royalty Evaluation by Experts).

               (iv) Frequency of Adjustment. A request to adjust the Royalty
Rate under this Section 4.1(c) (Exceptional Adjustments) cannot be made more
frequently than [****].

          (d) Changes. Any adjustments to Royalty Rate under Section 4.1(c)
(Exceptional Adjustments) shall apply only to Sales made after the adjustment,
and all royalties paid or due hereunder are non-refundable. In no event shall
the Royalty Rate under this Agreement be less than zero.

          (e) Royalty Payments. If the Royalty Rate is determined under Section
4.1(a) (Royalty Rate in General), then VentureCo shall pay E a royalty equal to
the Royalty Rate multiplied by the Licensed Product Revenue. If the Royalty Rate
is determined in accordance with Section 4.1(f) (Alternative Royalty Rate
Calculation Based on MNIP), then (i) VentureCo shall pay E a royalty equal to
the respective Royalty Rate multiplied by Net Sales Price of each Licensed
Product Sold by VentureCo in the respective period that incorporates the MNIP
into or uses the MNIP in the manufacture of such Licensed Product, and (ii) if
the Royalty Rate is determined on a per unit basis (such as watts) then the Net
Sales Price will be determined on the identical units and the product of these
shall be multiplied by units Sold. VentureCo shall pay the royalty on a calendar
quarterly basis, within [****] days of the end of the respective calendar
quarter.

          (f) Alternative Royalty Rate Calculation Based on MNIP. The provisions
in this Section 4.1 (f) (Alternative Royalty Rate Calculation) shall be used to
determine the Royalty Rate, only in the particular circumstances for which this
Section is applicable as set forth in Section 4.1(a) (Royalty Rate in General).

               (i) The "Base Rate" means [****]% of the Cost Savings plus
[****]% of the Added Value that was not already captured by the Cost Savings.
The Royalty Rate applicable to any particular year shall depend on the [****]
and the Base Rate in accordance with the following:

               (ii) In accordance with the above table, the Royalty Rate equals
the Base Rate in the [****] and [****] thereafter. [****] in the above table to
which respective Royalty Rates apply start upon the date of the first sale in
commercial volumes of the Licensed Products


                                      -9-

<PAGE>

incorporating the respective MNIP. Successive [****] start on successive [****]
of the date of such first sale. For example, if such first sale were to take
place on [****].

               (iii) Notwithstanding the foregoing, the royalty for any
particular item of MNIP shall not exceed [****]% of (Net Sales Price of the item
embodying the MNIP (e.g., Wafer, Cell, or Module) - Incoming Product Purchase
Price) for thin ribbon MNIP through [****], and other than with respect to such
thin ribbon MNIP, the royalty for any particular item of MNIP shall not exceed
[****]% of (Net Sales Price of the item embodying the MNIP (e.g., Wafer, Cell,
or Module) - Incoming Product Purchase Price). If several different items of
MNIP are used for the same Licensed Product, royalty shall be due for each of
such items of MNIP, except that the total of all such royalties shall not exceed
[****]% of (Net Sales Price - [****]). [****] but not the [****], (ii) the cost
of [****] in the event that MNIP relates to [****] but not the respective
[****], and (iii) [****] with respect to all other MNIP. For the purpose of
determining the [****], the costs of such [****] and [****] shall be determined
based on the prices at which Evergreen sells such products to third parties in
arm's length transactions in commercial volumes in the respective quarter, or if
no such arm's length transactions occur during such quarter, the market price of
multicrystalline silicon [****] and [****] sold in arm's length sales by third
parties and Evergreen in the respective quarter.

               (iv) For the avoidance of doubt, it is understood that the above
royalty calculations are not based on reduction in costs or added value due to
factors other than the respective MNIP. Further, it is understood that to the
extent that the benefit is provided by more than one item of MNIP, the royalty
for the respective items of MNIP shall be determined so as not to double count
the same benefit provided for the same Licensed Product.

               (v) [Deleted]

               (vi) Notwithstanding the above, in the event that the value and
savings is not properly reflected through a royalty determined through the
requirements set forth above, the parties shall promptly determine through good
faith negotiation the [****] royalty applicable to such MNIP based on the value
of such MNIP to EverQ. For example, in the event that the respective MNIP is
predominantly a cost savings technology, the component of the Base Rate
determined under this Section 4.1 (f) (Alternative Royalty Rate Calculation
Based on MNIP) based on Cost Savings may be increased from [****]%, up to a
maximum of [****] %. It is further agreed that the Value Added component
attributable to thin wafer technology will be deemed to have value until [****].
Additionally, if the Royalty Rate determined in accordance with the above is not
commercially reasonable (e.g., either too high or too low) because of unforeseen
factors, the parties shall negotiate a Royalty Rate determined under this
Section 4.1 (f) (Alternative Royalty Rate Calculation Based on MNIP) that is
commercially reasonable in view of the value of the technology to EverQ and the
market for such technology. As another example, in the event that a royalty is
originally structured with a meaningful percentage attributed to Added Value and
the Parties later determine that the Added Value has been eliminated or
substantially reduced, the Parties agree to negotiate in good faith an increase
in the amount of component of the Base Rate attributed Cost


                                      -10-

<PAGE>

Savings as would have occurred had the royalty originally been structured around
Cost Savings alone.

               (vii) In the event that, in view of the respective [****]
(collectively, "COSTS/VALUE"), Licensed Products that include the MNIP are
[****] than products made with [****], then the Royalty Rate for such MNIP shall
be [****] such that in view of the Costs/Value, the Licensed Products having the
[****]. Notwithstanding the foregoing, the Royalty Rate shall never be less
[****].

               (viii) The Party asserting that, based on Sections 4.1(f)(v) -
(vi), a Royalty Rate should be different from a royalty determined in accordance
with the mechanism set forth in Sections 4.1(f)(i) - (iv) above, or that any
Royalty Rate or component thereof already established under Section 4.1(f)
should be changed in accordance with the mechanism set forth above, shall have
the burden of proof of showing that the alternative approach should be adopted.

               (ix) Any adjustments to royalty shall apply on a going forward
basis only (ie apply only to Sales made after the adjustments), and all
royalties paid hereunder are non-refundable. In the event that the parties do
not agree on the applicable Royalty Rate, the parties shall appoint a mutually
agreed independent auditor who shall determine the Royalty Rate in accordance
with the above and whose determination shall be binding; provided, however, that
the Royalty Rate may be readjusted [****] months or later after the auditor's
determination based on changed circumstances.

          (g) "Used For." MNIP is "USED FOR" Licensed Products (for purposes of
SECTION 4.1 (Royalty)) if incorporated into or used in the manufacture of those
Licensed Products

          (h) Royalty - MNIP developed and available in the [****] Post
Termination Period (not available in the Initial Period)

               (i) The royalty payable for the use of MNIP developed and
commercially available in the [****] Termination Period is the Market Rate
royalty. The Parties shall promptly enter into arm's length negotiations in good
faith to determine the Market Rate royalty applicable to MNIP (of that
description) that VentureCo wishes to acquire in that period. Either Party may
initiate valuation/determination of the Market Rate royalty by experts subject
to SECTION 4.2 (Royalty Evaluation by Experts).

               (ii) That royalty agreed or determined (as applicable) under this
Section 4.1(h) shall be the Market Rate royalty. The royalty will be calculated
on a quarterly basis on all Licensed Products for which the MNIP was used, that
were sold in that quarter.

          (i) Royalty - on E IP and MNIP Post Termination

               (i) VentureCo shall continue to be responsible for royalty for
MNIP used after the Termination Date. Additionally, VentureCo shall pay E a
royalty on any other E IP used (prior to and at the Termination Date) for
Licensed Products sold in volumes in excess of the


                                      -11-

<PAGE>

Termination Level Capacity. That royalty shall be [****] percent ([****]%) of
the Market Rate royalty during the the first [****] years after the Termination
Date and the Market Rate royalty thereafter.

               (ii) Parties shall enter into arm's length negotiations in good
faith to determine the Market Rate royalty at commencement of the Post
Termination Period for E IP not currently or previously subject to royalty
payments. Either Party may initiate determination or valuation of the Market
Rate royalty by experts subject to SECTION 4.2 (Royalty Evaluation by Experts).
The agreed or (as applicable) specified royalty shall be the Market Rate
royalty. The royalty will be calculated on a quarterly basis on all Licensed
Products for which the E IP or MNIP was used, that were sold in that quarter,
subject to SECTION 4.1 (Royalty Calculations).

          (j) Royalty - on external IPR offered by E. If E offers VentureCo IP
or MNIP which carries an external running cost to E (e.g. a license fee/royalty
to a third party holder of such Intellectual Property Rights), then the cost
incurred by E in connection with sub-licensing to VentureCo shall be borne in
its entirety by VentureCo; provided that the written agreement between VentureCo
and E for the licensing of such IP or MNIP expressly includes the amount of such
running cost. The aforementioned shall not reduce E's rights to royalty under
the rules above.

          (k) No royalty on VentureCo MNIP. Notwithstanding anything in this
Agreement, no royalty is due hereunder on Licensed Products incorporating any
MNIP, where the directly associated development costs of that MNIP are
substantially funded by VentureCo pursuant to written development agreements/
arrangements between VentureCo and E. This is without prejudice to the terms of
written development agreements/arrangements (if any) that provide for
proportionate or other royalty reduction, where those costs are partially funded
by VentureCo.

     4.2 Royalty Evaluation by Experts. If the Parties cannot agree on the
Market Rate royalty, Added Value or Cost Savings for MNIP within [****] days
after initiation or commencement of negotiations to determine such royalty or
value, then the following applies: Each Party shall retain at its expense an
independent professional Third Party expert with expertise evaluating licenses
in the photovoltaic industry.

          (a) Subject to execution of customary confidentiality agreements by
the independent experts, VentureCo and E shall provide or cause to be provided
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 [****] days after the [****] day period referenced above,
each Party shall submit a final proposal for the relevant Market Rate royalty,
Added Value or Cost Savings for MNIP with a supporting analysis prepared in
writing by its retained expert, to the other Party and to 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 [****] day period) satisfying the above criteria and the


                                      -12-

<PAGE>

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
Market Rate royalty, Added Value or Cost Savings for MNIP.

     4.3 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.

     4.4 Royalty Calculations. Royalties shall not be due with respect to
Licensed Products for which the purchase price has been refunded within [****]
of delivery. In the event that only part of the purchase price is refunded, the
royalty shall be applied in proportion to the amount of the purchase price not
refunded.

     4.5 Payment. To the extent applicable, VentureCo shall, within [****] 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.

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

     4.7 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.

     4.8 Audit. Each Party shall maintain complete and accurate accounting
records, in accordance with sound accounting practices, to support and document
the royalties or payments payable in connection with this Agreement. Such
records shall be retained for a period of at least [****] 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


                                      -13-

<PAGE>

may be) of more than [****] percent ([****]%) 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.

                                    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 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 REC, 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


                                      -14-

<PAGE>

Property Right Jointly Owned by VentureCo, E, Q and REC, or pay any fee related
thereto, VentureCo shall notify E, Q and REC, and E, Q and REC shall have the
right, at their option, to jointly control the filing, prosecution and/or
maintenance of any such Intellectual Property Right, provided that E, Q and REC
shall consult with and keep VentureCo reasonably informed of matters regarding
such filing, prosecution and maintenance. To the extent that E, Q or REC 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 party(ies), and
such other party(ies) 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(ies) shall consult with the other party(ies) and
VentureCo and keep such party(ies) 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.

               (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
or the REC IP provided under the REC License Agreement, VentureCo shall notify
E, Q and REC, and E, Q and REC shall have the right to jointly control the
filing, prosecution and/or maintenance of any such Intellectual Property Right,
and VentureCo, at E, Q and REC's written request, shall transfer and assign all
right to such Intellectual Property Right to the joint ownership of E, Q and
REC. In the event that either E, Q or REC elects not to participate in the
filing, prosecution or maintenance of any Right, the other party(ies) shall have
the right, at their/its option, to control the filing, prosecution and/or
maintenance of such Intellectual Property Right, and VentureCo shall, at such
party(ies') request, transfer and assign all of its right, title and interest to
such party(ies). In the event of such transfer, VentureCo retains a world-wide,
non-exclusive, non-


                                      -15-

<PAGE>

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.


                                      -16-

     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).

                                   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.

          (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.

     or, in each case, at such other address as may be specified in writing to
the other Parties hereto.

     9.3 Language. All documentation, communication and services in connection
with this Agreement in shall be in English.

     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. The same applies to any waiver
of this written form requirement.

          (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 and REC; provided, however, that neither Party shall be
obligated to obtain the consent of the other Party or other parties 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 Prior Agreement; Entire Agreement; Severability. This Agreement
supersedes and replaces the Prior Agreement. 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.

     9.8 Governing Law and Dispute Resolution. This Agreement shall be construed
in accordance with and governed by the laws of the Federal Republic of Germany.

     All disputes arising in connection with this Agreement or its validity or
any agreement provided herein which cannot be resolved by mutual agreement of
the Parties shall be finally settled in accordance with the Arbitration Rules of
the German Institution of Arbitration e.V. (DIS) without recourse to the
ordinary courts of law (except for challenges to the validity of shareholder
resolutions which shall be submitted to the competent court in Berlin, and
except where the Parties seek injunctions as provided in Section 9.7). The place
of arbitration is Berlin, Germany. The arbitral tribunal consists of three
arbitrators. The arbitrators must be capable of being appointed a judge in
accordance with the relevant German legal rules. The substantive law of the
Federal Republic of Germany is applicable to the dispute. The language of the
arbitral proceedings is English.

     9.9 Compliance with Laws and Regulations. Each Party will comply with all
applicable laws, regulations and ordinances.

     9.10 Export. No Party shall export or re export, directly or indirectly,
any technical information disclosed hereunder or direct product thereof to any
destination prohibited or restricted by the applicable export control
regulations, including the U.S. Export Administration Regulations and
regulations of Germany, without the prior authorization from the appropriate
governmental authorities. Without limiting the foregoing, E shall be responsible
for obtaining government approvals, permits or the like necessary for the export
of its technology from the United States to VentureCo in Germany, and VentureCo
shall be responsible for obtaining all government approvals, permits or the like
required for the import of any technology to VentureCo and into Germany and for
the export of any technology or products by VentureCo from Germany.

     9.11 Force Majeure. No Party shall be liable to another Party for failure
to perform its obligations under this Agreement if such failure is caused by any
event or condition not reasonably within the control and anticipation of the
affected Party, including, without limitation, by fire, flood, typhoon,
earthquake, explosion, strike, labor trouble or other industrial disturbance,
unavoidable accident, war (declared or undeclared), act of terrorism, sabotage,
embargo, riot, or any other cause beyond the control of the Parties, provided
that the affected Party promptly notifies the other Party


                                      -22-

<PAGE>

of the occurrence of such event or condition and takes reasonable steps
necessary to resume performance of its obligations so interfered with.

     9.12 Independent Contractors. The Parties hereto are independent
contractors. Nothing contained herein or done pursuant to this Agreement shall
constitute either Party the agent of the other Party for any purpose or in any
sense whatsoever, or constitute the Parties as partners or joint venturers.

     9.13 Third Party Beneficiaries. No provision of this Agreement is intended
to confer upon any person or entity other than the Parties hereto (and their
permitted assigns) any rights or remedies hereunder.

     9.14 Counterparts. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument. This Agreement
shall become effective when each Party hereto shall have received a counterpart
hereof signed by the other Party hereto.

     9.15 Condition.

share capital in EverQ is increased to Euro [****]; (ii) that such capital
increase is registered with the commercial register, and (iii) after
registration of such capital increase, Evergreen, Q-Cells AG and Renewable
Energy Corporation ASA holds shares in a total amount of Euro [****] each.

     This Agreement is entered into under the further conditions precedent that
the Competent Cartel Offices have issued a letter or formal decision that they
will not prohibit the increase of share capital in EverQ or that the respective
waiting periods provided for in the national merger control laws have elapsed
without any formal decision rendered or that the Competent Cartel Offices
confirmed that the transactions contemplated herein are not notifiable under the
applicable merger control law. Competent Cartel Offices means any national or
international agency, body or other entity to which the transactions
contemplated herein have to be notified under the applicable merger control
jurisdictions.
