PV Modules in amounts that exceed either the forecasted amounts for the first three months of a Rolling Forecast Report or that are in excess of the amounts
determined in accordance with Sections 1(c) and 1(d) regardless of the amounts set forth in any Rolling Forecast Report. 
 (f) Optional Quantity Increase. To the extent provided on Schedule 1, PowerLight shall have
the option to increase the quantity of PV Modules Evergreen agrees to sell hereunder on an annual, firm commitment basis (the “Option”). For any year subject to the Option, PowerLight must deliver to Evergreen written notice of its
intention to exercise the Option for such year no later than July 1st of the preceding year. 
 (g) Change Orders. Subject to the firm commitment obligations of Sections 1(c) (Firm Annual Commitments) and 1(d) (Firm Quarterly
Commitments), Buyer may, at any time up until eight (8) weeks prior to the shipment date, by change order, suspend performance of a Purchase Order in whole or in part, make changes in the quantities, method of shipment or place of shipment
of the PV Modules in a Purchase Order. Any Change Order increasing the quantity of requested PV Modules will become binding upon Evergreen only if such Change Order increases the quantity of PV Modules by no more than ten percent (10%), unless
Evergreen otherwise consents in writing to a greater quantity change. In addition, subject to the firm commitment obligations of Sections 1(c) and 1(d), Buyer may at any time change the shipment date to any subsequent date within the same calendar
Quarter as the original shipment date. Buyer shall not change shipment date of a Purchase Order so as to cause the Purchase Order to be shipped in a subsequent Quarter without Evergreen’s written consent. Buyer may request change orders outside
the restrictions described in this Section 1(g), which Evergreen may accept in its discretion. Buyer shall use good faith efforts to issue Change Orders only for good business reasons. 
 2. Price; Taxes. The prices for PV Modules sold under Purchase Orders issued by Buyers shall be on a per-Watt basis and are set forth on Schedule
1. Such prices shall be determined by the year of the shipment date stated in the Purchase Order, as more fully described on Schedule 1. The price for PV Modules shall be the price applicable to the destination, which shall be determined prior to
the time of shipment of the PV Modules to Buyer. Buyers shall not manipulate their orders in order to defeat the intent that it pay the price applicable to the destination of the PV Modules. Evergreen and Buyer will reasonably cooperate to help
minimize taxes applicable to the transactions hereunder. Evergreen shall promptly remit to Buyer in full any taxes paid by Buyer which are refunded to Evergreen in whole or in part. Notwithstanding anything herein, Buyer shall be solely responsible
for any taxes applicable to the sale of PV Modules hereunder (excluding Evergreen’s income taxes, which shall be borne solely by Evergreen).

 3. Shipment. 
 (a) General. Except as otherwise provided on Schedule 1 with respect to frameless PV Modules, Evergreen agrees to ship PV Modules to Buyer on the following shipment terms: Ex-works (EXW) (Incoterms 2000)
Evergreen manufacturing facilities in North America for delivery locations in North America, and Ex-works (EXW) Evergreen manufacturing facilities in Europe for delivery locations in Europe. Except as otherwise provided on Schedule 1 with respect to
frameless PV Modules, for shipment locations outside of North America and Europe, the shipment terms will be Ex-works (EXW) Evergreen manufacturing facilities in either North America or Europe, as reasonably requested by Buyer and subject to
availability of the respective product at the facilities. Evergreen shall effect shipment of the PV Modules on or prior to the estimated shipment date provided in Evergreen’s acknowledgement (“Shipment Deadline”). The Shipment
Deadline shall not be later than four (4) months following Buyer’s issuance of the Purchase Order acknowledged by Evergreen unless Buyer requests a shipment date later than four (4) months following Buyer’s issuance of the
Purchase Order, in which case the Shipment Deadline shall be such later date requested by Buyer. In addition, Evergreen shall use good faith efforts to deliver PV Modules earlier than the Shipment Deadline if Buyer’s Purchase Order requests an
earlier shipment date. Buyer may store at Evergreen’s expense any PV Modules shipped to Buyer more than five (5) days in advance of its requested shipment date acknowledged by Evergreen. Time is of the essence in this Agreement.
Performance by Subsidiaries of Evergreen’s shipment and other obligations hereunder shall be deemed to satisfy the respective obligation as if performed by Evergreen, and upon reasonable request from Evergreen, Buyer shall place Purchase Orders
with such Subsidiaries. The sale of PV Modules does not convey any license under any patent claims covering combinations of such PV Modules with any other devices or elements or to the process of making the PV Modules. 
 (b) Late Delivery . Any Purchase Orders issued by Buyer and duly acknowledged by Evergreen shall, subject to the change order provisions of
Section 1(g) (Change Orders), give rise to a full take or pay obligation on Buyer. In the event PV Modules are shipped more than fourteen (14) days following the Shipment Deadline, Evergreen will pay Buyer late delivery penalties of
*** of the gross purchase price stated in the applicable Purchase Order for the units shipped late, plus additional penalties of *** of such price per week thereafter for such units shipped late, up to a maximum of *** of such price for such units
shipped late, and Evergreen’s liability for late delivery shall be limited to such penalties and any applicable quarterly and/or annual liquidated damages pursuant to Schedule 1. Such penalties shall be credited against the gross purchase price
otherwise payable by Buyer. Buyer may cancel by written notice any Purchase Order for PV Modules not delivered within *** of the Delivery Deadline and Buyer shall have no further liability under such Purchase Order to Evergreen. PowerLight shall
have the right to reduce PowerLight’s minimum quantity of MWp to be purchased in the applicable year of delivery by the MWp quantity represented by such canceled units of PV Modules by providing a specific notice of the reduction of the minimum
quantity along with PowerLight’s notice of cancellation of the Purchase Order.

 4. Packaging; Shipping; Testing. Evergreen shall bear all costs associated with packaging in
Evergreen’s standard packing or storing the PV Modules until shipment to Buyer pursuant to the shipment terms specified in Section 3(a). All PV Modules shall be reasonably packaged, marked, and otherwise prepared in accordance with good
commercial practices to reduce the risk of damage and to reasonably minimize shipping rates, in accordance with all applicable federal, state and local packaging and transportation laws and regulations. An itemized packing list shall accompany each
shipment. Prior to shipping, Evergreen shall deliver to PowerLight via e-mail a packing list showing PV Module serial numbers, their corresponding flash test data (including Pmp, Vmp, Imp, Voc, Isc and fill factor) and quality assurance test
indications. All shipped PV Modules shall satisfy the foregoing criteria, including the applicable module power tolerance standards set forth on Schedule 1. PV Module electrical characteristics shall be determined based on the results of production
line tests performed at the connectors in accordance with IEC 904-1 at ‘Standard Test Conditions’ (1000 W/m2 with IEC904-3 or equivalent IEEE reference solar spectral irradiance distribution, AM1.5 and 25C). Evergreen shall mark
on containers handling and loading instructions, shipping information, the order number, the PowerLight pan number and account, the shipment date and the names and addresses of Evergreen and PowerLight. 
 5. Title and Risk of Loss. Pursuant to Section 3(a) (General) above, title and risk of loss shall pass to Buyer upon shipment of the
PV Modules. 
 6. Invoicing. After each delivery completed under this Agreement, Evergreen shall send a separate invoice, including
item numbers, in duplicate, accompanied by a bill of lading or express receipt. Invoices may be provided in hard copy or electronic form. Subject to the foregoing, Buyer shall pay Evergreen all properly invoiced amounts within *** of the date of
product transfer from Evergreen to Buyer’s designated freight carrier (“Payment Due Date”). Subject to a mutually agreed credit limit, which the Parties agree shall be reviewed annually and shall be based on 120 day payment
terms and reflect PowerLight’s firm commitment quantity obligations under this Agreement, Buyer will pay Evergreen daily interest at the rate of prime plus *** per annum for any late payment made after their respective Payment Due Date until
ninety (90) days after its Payment Due Date, after which Buyer will pay Evergreen daily interest at the rate of *** per annum until payment is made; provided that the foregoing provisions shall not apply to Purchase Orders involving assignment
of rebate incentives to Evergreen. All accrued interest payment obligations shall be paid by PowerLight quarterly (“Quarterly Payment Obligations”). Notwithstanding anything to the contrary, the interest hereunder shall not exceed the
highest rate permitted by applicable law. Evergreen shall have the right to modify PowerLight’s credit limit, but only on an objective, reasonable, non-discriminatory basis consistent with ordinary business practices, with notice to PowerLight;
provided, however, that in the absence of Buyer’s bankruptcy or PowerLight’s failure to meet its Quarterly Payment Obligations, any decision by Evergreen to modify PowerLight’s credit limit shall, in the event PowerLight notifies
Evergreen of its willingness to 

  

 6 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
continue to place Purchase Orders and receive shipments hereunder, relieve PowerLight of any further firm commitment purchase obligations and liquidated
damages for failure to meet such purchase obligations if Evergreen refuses to fulfill such Purchase Orders under the terms of the original credit limits. Subject to mutual agreement, Evergreen may accept assignment of rebate incentives for up to 180
days as form of secured payment for particular Purchase Orders. In connection with any such accepted rebate assignments, Buyer will pay Evergreen daily interest at the rate of prime plus *** per annum for any payments made after the applicable
Payment Due Date. Buyer will bear all risk for securing rebate payments. 
 7. Inspection 
 (a) All PV Modules destined to Buyer may be inspected and tested by PowerLight, its Subsidiaries, higher tier contractors (excluding in all cases any
direct competitors of Evergreen), and the U.S. Government, at PowerLight’s discretion (but with at least fourteen (14) days’ advance notice provided to Evergreen). PowerLight may conduct such inspection on Evergreen’s premises
during normal business hours, in which case Evergreen will provide without additional charge, all reasonable facilities and assistance for such inspections and tests. The specific categories subject to inspection and testing pursuant to this
Section 7(a) shall be limited to Evergreen’s manufacturing process from solar cell testing through final PV Module testing and packaging. The Parties expect that the inspection will emphasize PV Module flash test results, ensuring that the
test equipment is calibrated at appropriate frequencies, and ensuring the durability and integrity of the PV Module solder bonds. The frequency of such inspections shall be limited to minimize interruption of Evergreen’s operations and in any
event are not contemplated to occur more often than annually. Evergreen shall have the right to prohibit access to confidential portions of its non-PV Module production facilities and to require personnel participating in the inspection to be bound
by appropriate confidentiality agreements approved by Evergreen. Any PowerLight Affiliates or higher tier contractors participating in such inspection or testing shall be accompanied by PowerLight. Any PowerLight employees visiting Evergreen
facilities for purposes of such inspection or testing shall be qualified to conduct the applicable inspections and tests and shall agree to abide by Evergreen’s policies and rules. As used in this Agreement, “Affiliate” means,
with respect to either PowerLight or Evergreen, another Party directly or indirectly controlling, controlled by or under common control with, PowerLight Corporation or Evergreen, respectively. Evergreen shall make PV Module inspection records
maintained and retained by Evergreen available to PowerLight during the performance of this Agreement; provided, however, that Evergreen shall in any event retain all flash test data records for the applicable Evergreen warranty period. 

(b) No inspection, test, approval, or acceptance of the PV Modules shall relieve Evergreen from responsibility for any defects in the PV Modules or
other failures to meet the requirements of this Agreement or the Purchase Order. In any such event, the sole remedies 

  

 7 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
available to PowerLight will be those contained in Evergreen’s warranty conditions for the applicable PV Modules set forth on Schedule 3. 
 8. Warranty. All PV Modules covered by this Agreement will be warranted per the conditions of the standard Evergreen warranty statements, set
forth on Schedule 3; provided, however, that as between Evergreen and Buyer, the additional warranty provisions set forth in this Section 8 shall also apply to PV Modules and, to the extent Section 8 conflicts with Schedule 3,
Section 8 shall prevail. The additional warranty provisions set forth in this Section 8 shall not be transferable or assignable to the consumer purchaser or any other third party; provided, however that PowerLight shall be entitled to
bring claims for such additional warranty provisions on behalf of its customers. The remedies set forth in either these limited warranties or Schedule 3 shall be the sole and exclusive remedies provided under the extended term warranty. 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, unless such other warranties, obligations, or liabilities are expressly agreed to in writing signed and approved by Evergreen. 
 (a) Power Output. Evergreen warrants that for a period of ten (10) years commencing on the date ninety (90) days following its shipment of PV Modules to the original consumer purchaser that the power
rating at Standard Test Conditions will remain at 90% or greater of Evergreen’s Minimum Specified Power Rating. Evergreen further warrants that for a period of twenty-five (25) years commencing on the date ninety (90) days following
its shipment of PV Modules to the original consumer purchaser that the power rating at Standard Test Conditions will remain at 80% or greater of Evergreen’s Minimum Specified Power Rating. Power output performance shall be tested by Evergreen
(with PowerLight’s prior written consent) or by PowerLight (with Evergreen’s prior written consent). In the event that PowerLight and Evergreen disagree on power output performance, a third-party independent testing agency such as Sandia
National Labs or the National Renewable Energy Lab (or a mutually agreed equivalent) will be used to determine actual module performance. PowerLight and Evergreen will collaborate to ensure that this third party determination is agreeable to both
PowerLight and Evergreen. 
 (b) Reasonableness Standard. The reference to Evergreen’s “sole and absolute judgment” in
Schedule 3 shall be replaced with Evergreen’s “reasonable judgment”. 
 (c) Pervasive and Systemic Failure. The last
sentence of the first paragraph under the heading “Limitations and Conditions” on Schedule 3 shall be deleted and replaced with the following: “Except as provided below with respect to a Pervasive and Systemic Failure, the limited

  

 8 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
warranties do not cover any transportation costs for return of modules or costs associated with the installation, removal, or reinstallation of PV Modules.
Notwithstanding the foregoing, in the event of a Pervasive and Systemic Failure in the PV Module(s), this following shall apply: 
 (i) Upon PowerLight’s knowledge of the occurrence of a Pervasive and Systemic Failure, PowerLight shall promptly notify Evergreen, and shall provide, if known and as may then exist, a description of the failure, and the suspected lot
numbers, serial numbers or other identifiers, and delivery dates, of the failed PV Modules. PowerLight shall provide access to Evergreen to the failed PV Modules for testing and analysis. The Parties shall cooperate and work together to determine
the root cause. PowerLight and Evergreen shall consider, evaluate and determine a corrective action program, which shall not be effective until approved in writing by authorized officers of PowerLight and Evergreen; provided that (1) the
foregoing shall not reduce Evergreen’s obligations under its express warranty statements in this Section 8 or Schedule 3, (2) such corrective action shall be consistent with the provisions of Section 8(e)(ii), and
(3) approval of such corrective action program shall not be unreasonably withheld by either party. The parties shall reasonably cooperate to establish remedies to address the Pervasive and Systemic Failure commensurate with the severity of the
respective failure (subject to the maximum liability for certain costs set forth in Section 8(e)(ii)). 
 (ii) Upon
occurrence of a Pervasive and Systemic Failure, and except as otherwise reasonably agreed under Section 8(e)(i), Evergreen shall reimburse reasonable costs of transportation, installation, removal, reinstallation, field repair, testing,
packaging and shipping, and decommissioning and recommissioning the solar electric system (the “Collateral Costs”), in addition to the other remedies provided under Evergreen’s express warranty statements in this Section 8
and/or Schedule 3 (e.g. module replacement); provided that Evergreen’s maximum liability for Collateral Costs per occurrence shall not exceed *** of the original price of the affected PV Modules (provided that if actual Collateral Costs
significantly exceed this *** threshold, the Parties shall make good faith efforts to determine an appropriate cost allocation); and provided, further, that Collateral Costs shall not include unrelated routine maintenance costs. Evergreen and
PowerLight shall use reasonable efforts to identify and agree upon less costly and disruptive remedies instead of those set forth in Section 8(e)(ii), where less costly and disruptive remedies are adequate for customers in view of the defects
involved. 
 “Pervasive and Systemic Failure” means confirmed failures in the PV Modules (i) mutually verified by
Evergreen and PowerLight (either itself or by an independent third party on behalf of PowerLight), (ii) occurring during the applicable warranty period, (iii) resulting from defects in materials, workmanship, manufacturing process or
design, in each case that cause a failure that would result in a claim under the express warranty provided to the customer, and (iv) occurring on more than the greater of ten (10) modules per project or 0.5% of the PV Modules per project.
It is 

  

 9 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
understood that a project may include multiple buildings and arrays that are provided as part of a single project. 
 (d) Force Majeure. The language in Schedule 3 “...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.” shall be deleted and replaced with the following: “...and any unforeseen similar event beyond its control.” 

(e) Warranty Claimants. Evergreen provides the warranty set forth in Schedule 3 to Buyer and its Customers. Buyer and its service providers
shall receive, document, and notify Evergreen of claims, questions or concerns under Evergreen’s warranty with respect to PV Modules sold to Buyer hereunder. Buyer shall obtain information from the customer as requested by Evergreen to enable
the parties to determine whether the respective claim arises under the Evergreen warranty or arises from materials or services not provided by Evergreen. In the event of a claim by Buyer or its customer under Evergreen’s warranty,
Evergreen’s satisfaction of the claim with respect to the customer purchaser shall be deemed to also satisfy the same claim with respect to Buyer. 
 (f) Indemnity. Evergreen shall defend, indemnify and hold harmless PowerLight and its Affiliates from any third party claim covered by the express warranty statements set forth on Schedule 3, subject to the
terms and limitations set forth therein. PowerLight shall defend, indemnify and hold harmless Evergreen and its Affiliates from any third party claim covered by the express warranty statements PowerLight has made to such third party, subject to the
terms and limitations agreed to by the third party. In the event that a party has a direct claim under an express warranty, such party’s rights shall be directly under such warranty and not under the foregoing indemnity. 
 9. Material. If PowerLight and/or other Buyers furnishes any material (such as framing materials, extrusions, mounting materials, fasteners, etc.)
for fabrication hereunder, and if Evergreen agrees to use of the material and the custom work, Evergreen agrees (a) not to substitute any other material in such fabrication without PowerLight’s prior written consent, (b) title to such
materials shall not be affected by incorporation in or attachment to any other property, (c) all such material (except that which becomes normal industrial waste) will be returned in the form of products or unused material to PowerLight (at
PowerLight’s expense in the case of unused material) and (d) no such material itself will be used by Evergreen for any purpose other than meeting PowerLight’s request.

	 ***
	 2007/2008/2009 Price Adjustment Mechanism: Pricing for 2007, 2008 and 2009 shall be subject to adjustment as
follows: by October 1st of the year (the “Baseline Year”) preceding the year subject to pricing
adjustment (such year being 2007, 2008 or 2009 and referred to as the “Adjusted Year”), PowerLight shall submit to a mutually agreed third party consultant data evidencing PowerLight’s (i) actual costs for photovoltaic modules
delivered in the Baseline Year from suppliers other than Evergreen and (ii) costs for photovoltaic modules which PowerLight is, as of such October 1st date, under a firm contractual commitment (through confirmed purchase orders or written firm commitment agreements) to purchase in the Adjusted Year from suppliers other than Evergreen. The foregoing
data shall be provided to such third party consultant under a nondisclosure agreement satisfactory to PowerLight, and shall not be disclosed to Evergreen. PowerLight and Evergreen shall equally bear the fees and expenses of such consultant.

 Based on such data, the third party consultant shall calculate
the average price paid or payable by PowerLight per watt in each of North America, Europe and Asia, excluding Evergreen orders for the Baseline Year and the Adjusted Year. Such average prices shall be calculated by multiplying the total amount paid
or payable by PowerLight in each geographic market divided by the total watts received or receivable for such monetary amounts in such market. Based on these average prices of dollars or euros per watt (as applicable) for the Baseline Year and the
Adjusted Year, prior to October 31st of the Baseline Year the third party consultant shall calculate, for each
of North America, Europe and Asia, the percentage increase (the “Percentage Increase”) or decrease (the Percentage Decrease”) in the average price from the Baseline Year to the Adjusted Year. 
 The price adjustment for PV Modules for the Adjustment Year shall be calculated as follows: to the extent there is a Percentage Increase, the PV Module
pricing shall be increased by a percentage calculated as follows: 
 Adjustment Year PV Module pricing percentage change = *** + Percentage
Increase 
  

 3 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 To the extent there is a Percentage Decrease of ***or less, there shall be no adjustment to the
Adjustment Year PV Module pricing. To the extent there is a Percentage Decrease of more than ***, the Adjustment Year PV Module pricing shall be decreased by a percentage calculated as follows: 
 Adjustment Year PV Module pricing percentage change = *** - Percentage Decrease 
 With respect to the 2008 pricing adjustments, if any, the 2007 PV Module pricing used for the Baseline Year shall reflect any pricing adjustments made to
2007 PV Module pricing in the previous year pursuant to the foregoing provisions. With respect to the 2009 pricing adjustments, if any, the 2008 PV Module pricing used for the Baseline Year shall reflect any pricing adjustments made to 2008 PV
Module pricing in the previous year pursuant to the foregoing provisions. 
 Notwithstanding the foregoing price adjustments described in this Schedule 1, the price adjustments shall only apply to Purchase Orders that are not acknowledged by Evergreen (acting in accordance with its acknowledgment deadline required
under Section 3(a) of the Agreement) as of October 1st of the Baseline Year. 
 Penalties/Liquidated Damages: The parties recognize and agree that, in the event of breach by either party of the promises contained herein
regarding quantity and price commitments, the damages suffered by the non-breaching party would be difficult to assess, and the liquidated damages set forth herein represent a reasonable assessment of the potential damage to the non-breaching party.

 Evergreen’s Failure to Meet Quantity Commitments: In any calendar year in which Evergreen fails to deliver the aggregate
quantities required for such year as set forth in this Schedule 1 above (as adjusted from time to time pursuant to Section 3(c) of the Agreement), Evergreen shall, no later than sixty (60) days following Evergreen’s receipt of
PowerLight’s written demand for such payment, pay liquidated damages to PowerLight in the amount of *** per kilowatt of shortfall. In addition to the foregoing liquidated damages, if any, in any quarter in which Evergreen fails to deliver the
aggregate quantities required for such quarter under Section 3(b) of the Agreement, Evergreen shall, no later than sixty (60) days following Evergreen’s receipt of PowerLight’s written demand for such 

  

 4 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
payment, pay liquidated damages to PowerLight in the amount of *** per kilowatt of shortfall; provided that the maximum number of kilowatts included in such
shortfall calculation shall be no more than *** of the aggregate kilowatt quantity required for the applicable year. 
 PowerLight’s
Failure to Meet Quantity Commitments: In any calendar year for which PowerLight fails to take delivery of the quantities required for such year as set forth in this Schedule 1 above (as adjusted from time to time pursuant to Section 3(c) of
the Agreement), PowerLight shall, no later than sixty (60) days following PowerLight’s receipt of Evergreen’s written demand for such payment, pay liquidated damages to Evergreen in the amount of *** per kilowatt of shortfall. In
addition to the foregoing liquidated damages, if any, in any quarter in which PowerLight fails to take delivery of the aggregate quantities required for such quarter under Section 3(b) of the Agreement, PowerLight shall, no later than sixty
(60) days following PowerLight’s receipt of Evergreen’s written demand for such payment, pay liquidated damages to Evergreen in the amount of *** per kilowatt of shortfall; provided that the maximum number of kilowatts included in

 EVERGREEN SOLAR 
 CEDAR LINETM AND SPRUCE LINETM 
 PHOTOVOLTAIC MODULES LIMITED 
 WARRANTY 
 Limited Warranty: 
 Materials or Workmanship 
 Evergreen Solar warrants the modules to be free from defects in materials or workmanship
under normal application, installation, use, and service conditions. If the product fails to conform to this warranty, then, for a period ending twenty-four (24) 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

		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 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 Civil 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 any way 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.
