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

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

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

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.

PowerLight may request new, customized PV Modules for a price mutually agreed; provided that the prices stated above are valid for PowerLight’s current product applications for roof systems, ground systems and parking systems, excluding SunTile™.

*** 2007/2008/2009 Price Adjustment Mechanism: Pricing for 2007, 2008 and 2009 shall be subject to adjustment as follows: by October 1^st 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 1^st 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 31^st 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 1^st 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
