      This License & Technology Transfer Agreement (this "AGREEMENT") is made by
and between Evergreen Solar, Inc., a Delaware corporation ("E"), and EverQ GmbH,
a limited liability company (GmbH), incorporated under the laws of the Federal
Republic of Germany ("VENTURECO"), as of the Signing Date. E and VentureCo are
hereinafter referred to individually by their respective names or as "PARTY" and
collectively as "PARTIES."

                                    RECITALS:

      WHEREAS, as of the Signing Date, E and Q-Cells AG ("Q") entered into that
certain Master Joint Venture Agreement (Notarial Deed nr. 7/2005 of the Berlin
notary public Dr. Rudolf von Hanstein, the "MASTER AGREEMENT") which is deemed
to be incorporated into this Agreement where this Agreement refers to the Master
Agreement (and remains incorporated notwithstanding termination of the Master
Agreement), pursuant to which, among other things, the Parties have agreed to
enter this Agreement;

      WHEREAS, as of the Signing Date, Q and VentureCo are entering into that
certain License and Technology Transfer Agreement (the "Q LICENSE AGREEMENT");

      NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties, covenants and agreements herein contained, and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged and accepted, and intending to be legally bound hereby, the
Parties hereto hereby agree as follows:

      That royalty agreed or determined (as applicable) shall be the Phase 2

      [*] Either Party may initiate determination or valuation of the [*]
      royalty by experts subject to SECTION 4.5 (Royalty Evaluation by Experts).
      The agreed or (as applicable) specified royalty shall be the [*] 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.

      (f)   ROYALTY - MNIP DEVELOPED AND AVAILABLE IN THE [*] POST TERMINATION
PERIOD (NOT AVAILABLE IN THE INITIAL PERIOD)

      The royalty payable for the use of MNIP developed and commercially
      available in the [*] Termination Period is [*] royalty. [*] Either Party
      may initiate valuation/determination of [*] royalty by experts subject to
      SECTION 4.5 (Royalty Evaluation by Experts).

      [*] 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.

      4.5   Royalty Evaluation by Experts. If the Parties cannot agree on the
Phase 2 Royalty, [*] royalty, or Added Value for MNIP within [*] 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 [*] 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 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 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 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

                                      -11-

                                                                    CONFIDENTIAL

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.

                  (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.

            (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

                                      -14-

(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.

                            CONFIDENTIAL INFORMATION

      7.1   Confidential Information. Any Confidential Information exchanged
pursuant to this Agreement (and the terms of this Agreement itself) will be
governed by SECTION 9.5 (Confidentiality) of the Master Agreement, with the
Parties hereunder deemed the Disclosing Party 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).

            (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.

DAMAGES.

      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.

      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). 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 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.
