relationship. It is the intent of the parties that this Agreement shall prevail
over the terms and conditions of any Purchase Order, acknowledgment form or
other instrument even if such Purchase Order, acknowledgment form or other
instrument purports to supersede these terms and is accepted by Evergreen unless
such Purchase Order, acknowledgment form or other instrument expressly
references this Section 2. Any other additional or different terms in Purchase
Orders, or other such documents of Purchaser in connection with orders or
acknowledgements are hereby deemed to be material alterations and notice of
objection to and rejection of them is hereby given.
     3. ANNUAL AND QUARTERLY COMMITMENTS
          (a) Annual Commitments. Evergreen agrees to sell to Purchaser, and
Purchaser agrees to buy Products, in each case, on an annual, firm commitment
basis, the aggregate quantities for the specified years set forth on Schedule 1
(for each applicable year, the “Annual Commitment”). Nothing in Section 3(b)
(Quarterly Commitments) or Section 3(c)(Product Type Allocation) shall require
Evergreen to sell to Purchaser more than, or allow Purchaser to purchase or
Evergreen to sell less than, the Annual Commitment.
          (b) Quarterly Commitments. No later than [****] of each calendar year,
Purchaser shall provide Evergreen with a binding forecast of the quantities of
total Product and corresponding quantities of each Product type that Purchaser
wishes to purchase in each respective Quarter of such upcoming year, which
quarterly quantities of Product and Product type shall be within twenty percent
(20%) and thirty percent (30%) of the applicable Annual Commitment and shall, in
the aggregate, equal Purchaser’s applicable Annual Commitment. Notwithstanding
Purchaser’s forecast, Evergreen’s shall only be obligated to provide for
shipment (i) in each Quarter Products in quantities ranging from a minimum of
twenty percent (20%) and thirty percent (30%) of the applicable Annual
Commitment and (ii) on an annual calendar year basis, the applicable Annual
Commitment; provided that in its binding forecast for the first Quarter of any
calendar year Purchaser may specify Products in quantities ranging from a
minimum of ten percent (10%) to a maximum of thirty percent (30%) of the
applicable Annual Commitment. Evergreen shall notify Purchaser no later than
[****] of the applicable year if Evergreen does not accept Purchaser’s forecast
for the full amount specified by Purchaser for each applicable Quarter in
Purchaser’s forecast. [****]
          (c) Product Type Allocation. Purchaser acknowledges that certain
elements of the Product manufacturing process limit Evergreen’s ability to
guarantee availability of volumes of different Product types at different times
as would be required to satisfy requests for

-2-

--------------------------------------------------------------------------------

 

specific Product types during each Quarterly and Annual Commitment period. In
establishing the Quarterly allocations for delivery pursuant to Section 3(b),
Evergreen agrees to use reasonable efforts to schedule Quarterly volumes that
give effect to Purchaser’s forecasted quantities of Product type for each
applicable Quarter and for each applicable Annual Commitment. Although Evergreen
reserves the right in its reasonable discretion to adjust the allocations of
Product types based upon actual production levels of different Product types and
Evergreen’s need to satisfy requests for allocations of different Product types
from its other customers, Evergreen agrees that it shall allocate Products types
to Purchaser or its Affiliates in a fair and equitable manner, and Purchaser and
its Affiliates will have no less than the pro rata access to different Product
types and power class as the average of Evergreen’s other customers that have
rights to use or sell Product in the Territory and have entered into multi-year
product purchase agreements for at least quarterly shipments.
          (d) Additional Orders. Orders for Products in excess of the applicable
Annual Commitments may be negotiated on a case by case basis; provided that,
unless otherwise agreed, if Evergreen and Purchaser agree to the terms of
Purchase Orders for quantities of Products in excess of any Annual Commitments,
such excess amounts will not count towards satisfaction of Purchaser’s Annual
Commitment for any subsequent calendar year.
     4. PURCHASE ORDERS
          (a) In General. Purchaser shall place Purchase Orders for and buy
Products in accordance with the terms and conditions of this Agreement.
Purchaser shall place Purchase Orders at least four (4) months in advance of the
respective requested shipment date.
          (b) Placement of Orders and Acceptance. Purchase Orders may be sent by
telefax or other electronic media approved by Evergreen and shall specify
Product type, quantity, destination, and requested shipment date. Purchaser’s
Purchase Orders shall request a shipment date. Provided a Purchase Order is for
Products within the required commitments of this Agreement, including the
forecast amounts accepted by Evergreen pursuant to Section 3 (Annual And
Quarterly Commitments) and the timing requirements set forth in Section 4(a) (In
General) , and does not conflict with the terms and conditions of this
Agreement, Evergreen shall acknowledge and accept such Purchase Order by written
notice or e-mail transmission delivered to Purchaser within [****] business days
following Evergreen’s receipt of such Purchase Order. Evergreen’s
acknowledgement shall provide expected shipment dates and quantities of each
Product type for the respective Purchase Order. Purchase Orders will be binding
upon Evergreen when accepted by Evergreen and confirmed by delivery of
Evergreen’s order acknowledgment according to this Section 4(b). Evergreen’s
failure to accept or reject a Purchase Order within [****] business days
following Evergreen’s receipt shall be deemed to constitute Evergreen’s
irrevocable acceptance of such Purchase Order.
          (c) Shipment Date and Rescheduling. [****]; provided, however, that
Purchaser shall not violate the other requirements of this Agreement including
Section 3 (Annual and Quarterly Commitments). For the avoidance of doubt,
Purchaser shall not reschedule Purchase Orders such that Purchaser would request
or accept shipment in the respective Quarter of less than the quantities
Purchaser is required to purchase in such Quarter under Section 3(b) (Quarterly
Commitments) or otherwise violate the terms of this Agreement.

--------------------------------------------------------------------------------

 

          (d) Placement of Orders by Affiliates. Evergreen shall accept Purchase
Orders meeting the requirements of this Agreement from third parties that are
Affiliates of Purchaser, provided that Purchaser has confirmed in writing that
such third parties are Affiliates. Such Purchase Orders shall be deemed to have
been made by Purchaser under this Agreement, and Evergreen shall have no legal
obligation to such Affiliates under this Agreement or under such Purchase
Orders. Purchaser shall be responsible for compliance with the terms and
conditions of this Agreement, including payment, with respect to any such
Purchase Order placed by its Affiliates, and shall indemnify and hold Evergreen
harmless for (i) any claims against Evergreen by such Affiliates, except for
claims resulting solely from Evergreen’s willful or grossly negligent conduct
outside the scope of this Agreement, or (ii) arising from the activities of such
Affiliates. Notwithstanding the foregoing, in the event that Purchaser
represents that an entity is an Affiliate of Purchaser from which orders are to
be accepted hereunder, Evergreen shall have the right to treat such orders as
Purchase Orders by an Affiliate of Purchaser under this Section 4(d) (Placement
of Orders by Affiliates) notwithstanding such entity’s failure to actually
qualify as an Affiliate as defined herein.
     5. PROVISION OF DATA
          (a) End User Statistics and Performance Data. Purchaser shall provide
Evergreen Quarterly reports detailing the location by country and channel in
which the Products are sold and installed, but only to the extent such
information is known by Purchaser and easily transmittable to Evergreen without
undue expense to Purchaser. Subject to the foregoing provision, such reports
shall be in a format and include information reasonably requested by Evergreen
including without limitation location information to the postal code level of
the respective sales and installations. In addition, upon Evergreen’s reasonable
request, Purchaser shall provide semi-annual performance monitoring data for all
Purchaser’s installations for which monitoring data is available and easily
transmittable to Evergreen without undue expense to Purchaser and provided that
Purchaser has the right to share such data. Purchaser will use reasonable
commercial efforts to request the right to share data with Evergreen and to the
extent it cannot share data if the names of end users are associated with the
data Purchaser will share the data anonymously to the extent permitted by law.
          (b) Flash Test Data. Evergreen shall provide Purchaser with Flash Test
Data for the Products in each shipment at the time of shipment. The Flash Test
Data so provided will be collected by measurements taken using high quality
procedures and equipment.
     6. SHIPMENT
          (a) Shipment. Except as otherwise may be agreed by Evergreen and
Purchaser in writing, Evergreen will deliver the Products [****] (Incoterms
2000) under accepted Purchase Orders at Evergreen’s facility in Devens,
Massachusetts USA or such other facility as Evergreen shall later designate
[****.] Evergreen will make available for shipment such Product [****] and
Purchaser will be responsible for all freight, handling, insurance, other
transportation charges, and import duties for such shipment; provided that if
any duty is imposed on exports from the United States that would apply to the
Products, Evergreen shall pay such duties. Evergreen shall use commercially
reasonable efforts to make the Products available for shipment in accordance
with the estimated shipment date provided in Evergreen’s

-4-

--------------------------------------------------------------------------------

 

acknowledgement for each applicable Purchase Order, provided that when
establishing such estimated shipment date Evergreen will use commercially
reasonable efforts to adhere to Purchaser’s requested shipment date.
          (b) Shipment Timing.
               (i) Evergreen shall use commercially reasonable efforts to make
the Products available for shipment in accordance with the estimated shipment
date provided in Evergreen’s acknowledgement for each applicable Purchase Order.
               (ii) [****]
               (iii) [****]
          (c) Packaging; Inspection Prior to Shipment. All Products shall be
prepared for shipment in a manner that follows commercially reasonable practices
and is reasonably adequate to ensure safe arrival. Prior to accepting the
Products for shipment at the Evergreen’s facility, Purchaser or its agent must
report any visible damage to packaged Products. If no such visible damage or
packaging concerns are reported at such time, Purchaser shall be deemed to have
accepted that the Products were properly packaged for shipment in acceptable
physical condition in compliance with Evergreen’s packaging obligations.
Acceptance or deemed acceptance of the Products as properly packaged for
shipment shall in no way reduce Purchaser’s right to inspect Products or
properly reject the Products pursuant to Section 14 (Product Quality Inspection)
or limit any warranty obligations pursuant to Section 13 (Warranty Services).
          (d) Title, Risk of Loss, Security Interest. Title to the Products
passes to Purchaser when the goods are placed in the custody and control of the
common carrier at Evergreen’s facility, from which point Purchaser is
responsible for all risk of loss or damage.
          (e) Delays in Delivery. Evergreen shall announce definitive collection
dates at its facility for Purchase Orders to be picked up by the applicable
common carrier on behalf of Purchaser. [****]
          (f) [****]
     7. PRODUCT CHANGES
     Evergreen shall have the right to make any changes to the Products that do
not affect the form, fit or function of the Products without notice. In the
event that Evergreen knows of proposed changes to the Specifications that will
affect the appearance, performance, form, fit or function of the Products,
Evergreen will use commercially reasonable efforts to inform Purchaser at least
ninety (90) days in advance prior to implementing such changes. Evergreen shall
not incur any liability thereby or any obligation to provide such changes or
improvements on Products previously purchased or sold by Purchaser. If such
changes cause Purchaser (or its Affiliates’) to cancel or modify Purchase Orders
because Purchaser’s (or Affiliates’) end users refuse to accept the Products as
modified, then Purchaser (or its Affiliates) will not incur any

-5-

--------------------------------------------------------------------------------

 

liability as a result of such change or cancellation in any Purchase Order and
the Quarterly requirements represented by such changes or cancellations, as the
case may be [****]

payments, unless alternative arrangements have been agreed upon.

     Purchaser shall distribute the Products purchased from Evergreen hereunder
solely for sale, directly or indirectly, to end users in the Territory.

     10. TERM AND TERMINATION
          (a) Term. This Agreement shall commence on the Effective Date and
shall terminate on the Termination Date. The term of this Agreement shall be
extended for additional one (1) year terms to the extent that the parties agree
to minimum quantities and prices applicable to such years and the parties

-6-

--------------------------------------------------------------------------------

 

material breach regardless of the amount of such non-payment or (ii) sixty
(60) days after receipt of written notice from the party not in default, for
other material breaches. In addition to the foregoing Purchaser may terminate
this Agreement by written notice to Evergreen pursuant to (and without any right
of cure) as specified Section 14 (a)(ii) and (iii) and Section 6 (b)(iii) as
such termination rights are specified in those sections.
          (c) Effect of Termination. Upon termination of this Agreement by
Evergreen for cause under Section 10(b) (Termination for Cause) above, Evergreen

further obligation. Similarly, upon termination of this Agreement by Purchaser
for cause under Section 10(b) (Termination for Cause) above, Purchaser may, at

Liability for Termination), 11 (Intellectual Property), 12 (Confidentiality), 13

extended period.

this Agreement.

other proprietary rights embodied in the Products and User Documentation and all
modifications and derivative works of any of the foregoing that are owned or

reasonable evidence that Purchaser is establishing itself as a supplier of
Product to a particular market in the Territory with a market size that equals
or exceeds twenty (20) MW, Evergreen shall within a reasonable period of time
following such request provide Purchaser with a foreign language translation of
the User Documentation for the applicable jurisdiction.
          (d) Trademarks. The parties may use each other’s trademarks, trade
names, logos or service marks (collectively, “Trademarks”) in connection with
such party’s promotion and distribution of Products only after obtaining the
prior written consent of the other party on a case-by-case basis, in its sole
discretion, provided that Purchaser may identify Evergreen as the manufacturer
and/or supplier of the Products, and Evergreen may identify Purchaser as a
distributor of the Products, as the case may be without the need for consent of
the other party. Each party’s use of the other’s Trademarks shall fully comply
with all guidelines that may be provided by one party to the other concerning
the use of the Trademarks. All use of the Trademarks of one party by the other
shall inure solely to the benefit of the trademark holder, and neither party
shall obtain any rights with respect to any of the Trademarks of the other.
Purchaser and its direct and indirect customers shall retain the Trademarks as
the Trademarks appear on the Products and User Documentation.
          (e) Proprietary Notices. Purchaser shall not remove any copyright,
patent, Trademark or other proprietary notices, markings or legends from the
Product or User Documentation and shall reproduce all such notices, markings and
legends on all copies of the Product and User Documentation permitted under this
Agreement.
          (f) No Implied Licenses. No licenses are granted either expressly or
by implication, estoppel or otherwise to Purchaser or Evergreen under this
Agreement except as expressly set forth in this Section 11 (Intellectual
Property) and as implied by Evergreen’s right to use Purchaser data in 5(a)
(Customer Statistics and Performance Data) and as implied by Purchaser’s and its
Affiliates’ and their respective customers’ right to use Products supplied
hereunder. ALL RIGHTS NOT EXPRESSLY GRANTED HEREIN ARE RESERVED TO EVERGREEN OR
PURCHASER, AS THE CASE MAY BE, OR THEIR RESPECTIVE LICENSORS.

          (a) Confidential Information. “Confidential Information” means
information in any form that may be disclosed by a party hereto (“Disclosing

Disclosing Party to a writing conspicuously marked “Confidential” or
“Proprietary” and given to the Receiving Party within thirty (30) days of such
oral disclosure; provided, however, that reports and/or information related to
or regarding the Disclosing Party’s

-8-

--------------------------------------------------------------------------------

 

business plans, business methodologies, strategies, technology, specifications,
development plans, customers, prospective customers, billing records, and
products or services will be deemed Confidential Information of the Disclosing
Party even if not so marked or identified unless such information is the subject
of any of the exclusions set forth in Section 12(b). Any confidential or
proprietary information embodied in the Products, and the copyrights in and to
the User Documentation are proprietary to Evergreen and, for that purpose, shall
be deemed to be the Confidential Information of Evergreen, whether or not marked
as described above, subject, however, to any of the exclusions set forth in
Section 12(b).
          (b) Exclusions. Notwithstanding the provisions of Section 12(a)
(Confidential Information), Confidential Information excludes information that
the Receiving Party can demonstrate in writing: (i) is or becomes part of the
public domain through no fault or breach of the Receiving Party; (ii) is
rightfully known to the Receiving Party prior to receipt from the Disclosing
Party, as shown by Receiving Party’s written records; (iii) is subsequently
rightfully obtained by the Receiving Party from a third party that has the legal
right to disclose such information to the Receiving Party; or (iv) is
independently developed by the Receiving Party without use of Disclosing Party’s
Confidential Information and without the involvement of Receiving Party’s
employees who had access to Disclosing Party’s Confidential Information.
Receiving Party shall be permitted to disclose Disclosing Party’s Confidential
Information if such disclosure is required by law, provided that the Receiving
Party provides the Disclosing Party with prompt written notice of such
requirement prior to such disclosure; or is permitted by the express terms of
this Agreement, or by implication in the case of the User Documentation.
          (c) Use and Disclosure. Each party agrees that it (i) shall use such
Confidential Information of the other party only to the extent reasonably
necessary to perform its obligations or exercise its rights under this Agreement
and (ii) shall not disclose, or permit to be disclosed such Confidential
Information, either directly or indirectly, to any third party except as
permitted under this Agreement or otherwise approved in writing by the other
party. In protecting the Confidential Information of the other party from
unauthorized use and disclosure, each party agrees to exercise the same care
that it takes to protect its own Confidential Information, but not less than
reasonable care. Notwithstanding the foregoing, Purchaser may disclose the
Product and User Documentation to third parties in connection with the marketing
and sale of the Products pursuant to this Agreement.
          (d) Confidentiality of Agreement. The terms and conditions of this
Agreement shall be treated as Confidential Information and shall not be
disclosed to any third party, except (i) with the other party’s consent, which
shall not be unreasonably withheld; (ii) as may be required by law or regulation
or in connection with public offerings or securities filings; (iii) in
confidence, to its legal counsel, accountants, investors and financial advisors;
(iv) in confidence, in connection with the enforcement of this Agreement or
rights under this Agreement; and (v) in confidence, as reasonably required in
connection with a financing or merger or acquisition of all or substantially all
of the business or assets of Evergreen or Purchaser.
          (e) Publicity. The contents of any press release or publicity
disclosing any aspect or the existence of the business relationship contemplated
by this Agreement shall be subject to mutual agreement of the parties. Neither
party shall issue any such press release or

-9-

--------------------------------------------------------------------------------

 

publicity without the prior written consent of the other party unless such
disclosure is required by law. Notwithstanding the foregoing, the parties shall
discuss and cooperate to issue a mutually agreed upon press release promptly
upon execution of this Agreement.

to or requested by Purchaser, (iii) any modification of any Product by Purchaser
or its Affiliates, (iv) Purchaser’s failure to install or have installed
changes, revisions or updates as instructed and paid for by Evergreen,
(v) Evergreen’s compliance with Purchaser’s or an end user’s specifications,
designs or instructions, or (vi) use of any Product in material violation of
this Agreement, the User Documentation, or Evergreen’s reasonable written
instructions.
          (c) Procedure. Each party’s (“Indemnifying Party’s”) indemnification
obligation is subject to the conditions that (i) the other party (“Indemnified

and provides the Indemnifying Party with sole control of the defense of such
claim and all negotiations for any settlement or compromise, and (ii) the
Indemnified Party provides all information and assistance reasonably requested
by the Indemnifying Party (but without cost or expense to the Indemnified Party)
for the defense and settlement of such claim.

Schedule 3
Warranty
(EVERGREEN SOLAR LOGO) [b71172esb7117201.gif]
SPRUCE LINE™ photovoltaic modules
Limited Warranty
Limited Warranty: Materials or Workmanship
Evergreen Solar warrants the modules to be free from defects in materials or
workman-ship under normal application, installation, use, and service
conditions. If the product fails to conform to this warranty, then, for a period
ending sixty (60) months from date of sale to the original consumer purchaser,
Evergreen Solar will, at its option, either repair or replace the product or
refund the purchase price. The repair, replacement, or refund remedy shall be
the sole and exclusive remedy provided under this warranty.
Limited Warranty: Power Output
Evergreen Solar warrants for a period of ten (10) years from the date of sale to
the original consumer purchaser that the power rating at Standard Test
Conditions will remain at 90% or greater of Evergreen Solar’s Minimum Specified
Power Rating. Evergreen Solar further warrants for a period of twenty-five
(25) years from the date of sale to the original consumer purchaser that the
power rating at Standard Test Conditions will remain at 80% or greater of
Evergreen Solar’s Minimum Specified Power Rating.
Evergreen Solar will, at its option, repair or replace the product, refund the
purchase price, or provide the purchaser with additional modules to make up lost
power, provided that such degradation is determined to be due to defects in
materials or workmanship under normal installation, application, and use. The
relevant Minimum Specified Power Rating is defined in Evergreen Solar’s product
data sheet at the time of shipment. Standard Test Conditions are irradiance of
1000 W/m2, 25° C cell temperature, and AM 1.5 light spectrum.
Limitations and Conditions
The remedy set forth in these limited warranties shall be the sole and exclusive
remedy provided under the extended term warranty, unless otherwise agreed by
Evergreen Solar in writing. In Germany, these limited warranties are neither a
“guarantee of the quality” of the module pursuant to §443 BGB (German CiviI
Code) nor are they an “acceptance of a guarantee” pursuant to §276 BGB.
The limited warranties set forth herein do not apply to any module which in
Evergreen Solar’s sole judgment has been subjected to misuse, neglect, or
accident has been damaged through abuse, alteration, improper installation or
application, or negligence in use, storage, transportation, or handling; or has
in anyway been tampered with or repaired by anyone other than Evergreen Solar or
its agent.
The limited warranties do not cover costs associated with module installation,
removal, testing, packaging, transportation, or reinstallation; other costs
associated with obtaining warranty service; or costs, lost revenues, or lost
profits associated with the performance or nonperformance of defective modules.
Any modules repaired or replaced by Evergreen Solar under a warranty claim shall
be covered by the same warranties and original term as the first product
purchased under said claim. The term shall not be prolonged or reset from the
date of sale to the original consumer purchaser. Any replaced parts or products
become the property of Evergreen Solar.
These limited warranties apply only to the first end-user purchaser of the
modules or to any subsequent owners of the original building or site where the
modules were first installed. The limited warranties set forth herein are
expressly in lieu of and exclude all other express or implied warranties,
including but not limited to warranties of merchantability and of fitness for
particular purpose, use, or application and all other obligations or liabilities
on the part of Evergreen Solar, unless such other warranties, obligations, or
liabilities are expressly agreed to in writing signed and approved by Evergreen
Solar.
Evergreen Solar shall have no responsibility or liability whatsoever for damage
or injury to persons or property, or for other loss or injury resulting from any
cause whatsoever arising out of or related to the product, including, without
limitation, any defects in the module, or from use or installation. Under no
circumstances shall Evergreen Solar be liable for incidental, consequential, or
special damages, howsoever caused.
Evergreen Solar’s aggregate liability, if any, in damages or otherwise, shall
not exceed the payment, if any, received by seller for the unit of product or
service furnished or to be furnished, as the case may be, which is the subject
of claim or dispute. Some Jurisdictions do not allow limitations on implied
warranties or the exclusion or limitation of damages, so the above limitations
or exclusions may not apply to you.
If a part, provision, or clause of terms and conditions of sale, or the
application thereof to any person or circumstance is held invalid, void, or
unenforceable, such holding shall not affect and leave all other parts,
provisions, clauses, or applications of terms and conditions remaining, and to
this end the terms and conditions shall be treated as severable.
This warranty gives you specific legal rights; and you may also have other
rights that vary from state to state and country to country. Neither party shall
be in any way responsible or liable to the other party, or to any third party,
arising out of nonperformance or delay in performance of the terms and
conditions of sale due to acts of God, war, riot,, strikes, unavailability of
suitable and sufficient labor, and any unforeseen event beyond its control,
including, without limitations, any technological or physical event or condition
which is not reasonably known or understood at the time of sale.
Any claim or dispute regarding these warranties shall be governed by and
construed in accordance with the laws of the State of New York (US).
Obtaining Warranty Performance
If you feel you have a claim covered by warranty, you must promptly notify the
dealer who sold you the module of the claim. The dealer will give advice
handling the claim. If further assistance is required, write Evergreen Solar for
instructions.
The customer must submit a written claim, including adequate documentation of
module purchase, serial number, and product failure. Evergreen Solar will
determine in its sole judgment the adequacy of such claim. Evergreen Solar may
require that product subject to a claim be returned to the factory, at the
customer’s expense. If product is determined to be defective and is replaced but
is not returned to Evergreen Solar, then the customer must submit adequate
evidence that such product has been destroyed or recycled.
Note: This document may be provided in multiple languages. If there is a
conflict among versions, the English language version dominates.
