Section 4.1 Existence and Qualification. The Seller is a corporation duly organized, validly existing and in good standing under the Laws of the State of Delaware, has all power and authority to own its properties and to carry on its business as it is now being conducted, and is qualified as a foreign entity to do business under the Laws of each jurisdiction requiring such qualification, except where a failure to so qualify would not have a Material Adverse Effect.

Section 4.2 Authorization of Agreement. The Seller has full power and authority to enter into this Agreement and each Related Agreement to which it is a party and to consummate the transactions contemplated hereby and thereby and to perform its obligations hereunder and thereunder.

This Agreement and each of the Related Agreements to which it is a party have been duly executed and delivered by the Seller and constitute the valid and binding obligation of the Seller, enforceable against the Seller in accordance with their respective terms, except to the extent that their enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar Laws affecting the enforcement of creditors’ rights generally and by general equitable principles.

Section 4.3 Title to Certain Purchased Assets; Sufficiency of Purchased Assets. Seller has, and will convey to Purchaser at Closing, good and merchantable title to the Purchased Assets, free and clear of all Liens. Seller possesses sole, exclusive, valid and unencumbered title to the Purchased Assets, has not transferred any rights in any of the Purchased Assets, and all co-developers or inventors of the Intellectual Property have assigned all of their rights, if any, in the Purchased Assets to the Seller. The tangible property included among the Purchased Assets is in good working order and repair, reasonable wear and tear excepted, without the need for any

material repair or replacement. No Person other than the Seller owns any tangible or intangible property, including Intellectual Property, used in or necessary to the operation of the Single Axis Tracker Business (other than “off-the-shelf” software licensed pursuant to “click-through” or “shrink wrap” license agreements with annual fees of less than $500). Except for the Excluded Assets, the Purchased Assets constitute the assets that are of material importance to the ongoing operation of the Single Axis Tracker Business by Purchaser conducted in substantially the same manner as conducted by the Seller for the twelve-month period immediately prior to the date hereof. None of the Excluded Assets are material to the Single Axis Tracker Business.

Section 4.4 No Conflicts. Seller’s execution and delivery of this Agreement and each Related Agreement to which it is a party does not and the consummation of the transactions contemplated hereby will not:

(a) conflict with or result in a violation or breach of any of the terms, conditions or provisions of its corporate governing documents or any resolution approved by the Seller’s board of directors or stockholders;

For purposes of this Agreement, the term “Solvent” with respect to each of the Seller and the Seller Parent means that, as of any date of determination, (a) the amount of the fair saleable value of the assets of the applicable party, taken as a whole, exceeds, as of such date, the sum of (A) the value of all Liabilities of such party, taken as a whole, including contingent and other Liabilities, as of such date, as such terms are generally determined

With respect to TCA Global Master Credit Fund, L.P., Seller represents that such creditor has released secured claims in and to the Purchased Assets and waived any rights that might otherwise exist or arise with respect to the Purchaser or in connection with the transactions contemplated by this Agreement, and that Seller has delivered to Purchaser a true and correct copy of such release.

The Seller is not in default or violation, nor has it received any notice of any claim of default or violation, with respect to any such Permit.

(d) There has not been any generation, use, transportation, treatment, storage, release or disposal of any Hazardous Substance: on, in, under or emanating to or from the Premises which has created or could be reasonably expected to create any liability under any Environmental Laws which would require reporting to or notification of any governmental entity or any investigation or remediation thereof. The Premises are not listed on, or proposed for listing on, the National Priorities List (or CERCLIS) under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C.

(b) During the Restricted Period, Seller and the Seller Parent shall not, and shall not permit any of its Affiliates to, directly or indirectly, hire or solicit any Person, other than Persons that are employees of the Seller as of the date hereof, who is or was employed in the Business at any time during the Restricted Period, or encourage any such employee to leave or limit such employment or hire any such employee who has left such employment, except pursuant to a general solicitation which is not directed specifically to any such employees; provided that nothing in this Section 7.3(b) shall prevent Seller and the Seller Parent or any of its Affiliates from hiring (i) any employee whose employment has been terminated by Purchaser or (ii) after 180 days from the date of termination of employment, any employee whose employment has been terminated by the employee.

(d) Seller and Seller Parent each acknowledge that included in the Single Axis Tracker Business are certain Intellectual Property rights (including trade secrets, know-how, customer and prospect lists, vendors lists, pricing arrangements, financial statements, personnel files, and any and all other records pertaining to the operation of the Business) that Seller has used in the Single Axis Tracker Business and that have commercial value in the Single Axis Tracker Business and accordingly have been treated by the Seller as confidential. All such information (collectively, the “Confidential Information”) shall be kept confidential by Seller and the Seller Parent as provided below; provided, however, that the term “Confidential Information” shall not include information that is generally available to or known by the public through no fault of the Seller or any of its Affiliates. The terms and conditions of this Agreement, the Related Agreements and all other agreements entered into in connection with the foregoing agreements shall also be deemed Confidential Information. Seller and the Seller Parent each agree that on and after the date hereof, it and its Affiliates will keep in strictest confidence and trust all Confidential Information and neither such Seller or Seller Parent nor any of its Affiliates will, without Purchaser’s prior written consent, use or disclose any Confidential Information, except to the extent (i) necessary to comply with any legal requirements in connection with the Seller’s ownership or operation of the Business on or prior to the Closing Date, such as the filing of income tax returns or reports, (ii) Seller or Seller Parent or any of its Affiliates becomes legally compelled to disclose any of the Confidential Information, in which case, Seller or Seller Parent or its Affiliates, as the case may be, will provide Purchaser with prompt written notice so that Purchaser may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Section 7.3(d) and (iii) such Confidential Information set forth on

Schedule 7.3(d), hereto. If such protective order or other remedy is not obtained or Purchaser waives compliance with the provisions of this Section 7.3(d), the Seller or Seller Parent or its Affiliates, as the case may be, will furnish only that portion of the Confidential Information that is legally required.

(e) If Seller or the Seller Parent breaches, or threatens to commit a breach of, any of the provisions of this Section 7.3, Purchaser shall have the following rights and remedies, each of which rights and remedies shall be independent of the others and severally enforceable, and each of which is in addition to, and not in lieu of, any other rights and remedies available to Purchaser under law or in equity:

(i) the right and remedy to have such provision specifically enforced by any court having jurisdiction, including the right to injunctive relief (without posting a bond or other security), it being acknowledged and agreed that any such breach or threatened breach may cause irreparable injury to Purchaser and that money damages may not provide an adequate remedy to Purchaser; and

(ii) the right and remedy to recover from Seller all monetary damages suffered by Purchaser as the result of any acts or omissions constituting a breach of this Section 7.3.

(f) Seller and Seller Parent each acknowledge that the restrictions contained in this Section 7.3 are reasonable and necessary to protect the legitimate interests of Purchaser and constitute a material inducement to Purchaser to enter into this Agreement and consummate the transactions contemplated by this Agreement. The parties hereto agree that the covenants set forth in this Section 7.3 shall be enforced to the fullest extent permitted by applicable Laws and Regulations. In the event that any covenant contained in this Section 7.3 should ever be deemed by a court to exceed the time, geographic, product or service or other limitations permitted by applicable Laws and Regulations in the governing jurisdiction, then such court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service or other limitations permitted by applicable Laws and Regulations. The covenants contained in this Section 7.3 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

Section 7.4 Creditors; Liens. The Seller shall pay and be responsible for the timely satisfaction of any and all Non-Assumed Liabilities.

Section 7.5 Tax Cooperation; Allocation of Taxes.

(a) All personal property Taxes and similar ad valorem obligations levied with respect to the Purchased Assets for a taxable period which includes (but does not end on) the Closing Date (collectively, the “Apportioned Obligations”) shall be apportioned between the

Seller and the Purchaser as of the Closing Date based on the number of days of such taxable period included in the Pre-Closing Tax Period and the number of days of such taxable period included in the Post-Closing Tax Period. The Seller shall be liable for the proportionate amount of such Taxes that is attributable to the Pre-Closing Tax Period and the Purchaser shall be liable for the proportionate amount of such Taxes that is attributable to the Post-Closing Tax Period. To the extent that the Seller or the Purchaser has paid for the other party’s portion of the Apportioned Obligations, the Seller shall reimburse the Purchaser within thirty (30) days after a written request by the Purchaser is delivered to the Seller for the Seller’s portion of the Apportioned Obligations and the Purchaser shall reimburse the Seller within thirty (30) days after a written request by the Seller has been delivered to the Purchaser for the Purchaser’s portion of the Apportioned Obligations.

(b) Any transfer, documentary, sales, use or other Taxes assessed upon or with respect to the transfer of the Purchased Assets to Purchaser and any recording or filing fees with respect thereto shall be paid by Seller, and Seller shall promptly reimburse Purchaser for any such amounts paid by Purchaser.

(c) Prior to the Closing Date, Seller shall provide Purchaser with a clearance certificate or similar document(s) which may be required by any Governmental Entity in order to relieve Purchaser of (i) any obligation to withhold any portion of the Purchase Price and (ii) any liability for Taxes (determined without regard to the provisions of this Agreement assigning responsibility therefor) for which relief is available by reason of the filing of an appropriate certificate.

(d) Purchaser and Seller shall file all Tax Returns consistent with the Allocation Statement and shall not make any inconsistent written statements or take any inconsistent position on any Tax Return, in any refund claim, during the course of any U.S. Internal Revenue Service (“IRS”) audit or other Tax audit, for any financial or regulatory purpose, in any litigation or investigation or otherwise. Each party shall notify the other party if it receives notice that the IRS or other Governmental Entity proposes any allocation different than that set forth in the Allocation Statement. No later than ten (10) days prior to the filing of their respective Form 8594s relating to the transactions contemplated by this Agreement, each party shall deliver to the other party a copy of its Form 8594.

Section 7.6 Warranty Claims; Maintenance.

(a) Seller acknowledges and agrees that, after the Closing Date it will comply, in the ordinary course of business consistent with past practice by the Seller, with the terms and conditions of all product warranties relating to the Business and sold by the Seller prior to the Closing, including, but not limited to, warranties for replacement and/or repair of any such products and will fully perform and comply with all maintenance, monitoring and other service requirements of Excluded Contracts.

(b) Purchaser hereby acknowledges and consents to Seller’s direct and indirect (through subcontracting or otherwise) performance of replacement and/or repair work pursuant to product warranties relating to the Business entered into by Seller prior to the Closing Date.

Provided that Purchaser has the applicable inventory in stock, Purchaser shall, at a price based on Purchaser’s costs, fill Seller’s reasonable orders to purchase products and/or parts of the Business that are necessary to Seller’s performance of its pre-Closing product warranty obligations related to the Business. Purchaser shall, at a price based on Purchaser’s costs and subject to availability of personnel, provide consulting services relating to the Single Axis Tracker Business to Seller (or Seller’s designated third party warranty support provider) in response to Seller’s reasonable requests that are necessary to Seller’s performance of its pre-Closing product warranty obligations related to the Single Axis Tracker Business, provided however, that (1) Purchaser may, in its reasonable discretion, provide such services pursuant to terms and conditions reasonably satisfactory to Purchaser set forth on a separate side letter or purchase order and (2) Seller shall indemnify and hold harmless Purchaser for any claims or liability relating to the provision of such consulting services, except for claims or liability resulting from Purchaser’s intentional misconduct or bad faith.

(c) Notwithstanding Seller’s acknowledgement that it is responsible for all warranty and maintenance requirements pursuant to this Section 7.6, if at any time Purchaser incurs any costs in connection with Seller’s obligations hereunder, then, Seller shall reimburse the Purchaser for its reasonable out of pocket costs incurred to satisfy any such product warranty claims that are the responsibility of Seller in accordance with this Section 7.6. The Purchaser shall provide the Seller, on a monthly basis, if applicable, with a schedule and reasonable supporting documentation specifying the costs incurred by the Purchaser to satisfy any such product warranty claims. The Seller shall pay such costs within ten (10) business days following delivery of such schedule and the required documentation.

(d) Immediately following the Closing, Seller shall deliver the letters contemplated by Section 3.5(r) to all Persons to which Seller owes maintenance or warranty obligations.

Section 7.9 Know-How Transfer and Access. After the Closing, Seller and Seller Parent shall make reasonable efforts to make its employees available to Purchaser to transfer

know-how relating to the Intellectual Property to Purchaser for a period of one (1) year following the Closing.

Section 7.10 Insurance. Until such time as all of Seller’s maintenance and warranty obligations expire with respect to the Single Axis Tracker Business, the Seller shall maintain insurance covering (a) each Person currently covered by the Seller’s “directors and officers” and executive shield insurance policies, and (b) general liability and personal injury, with respect to matters or circumstances occurring at or prior to the Closing Date. Seller shall maintain the coverage levels of such policies at reasonable and customary levels. Seller shall, within thirty (30) days of Closing, add Purchaser as an additional insured for each such policy, entitled to receive thirty (30) days prior notice of all material changes to or cancellations of such policies. Until such time as Seller’s insurer agrees to notify Purchaser of all material changes to such policies, Seller shall provide Purchaser with thirty (30) days advance written notice of all material changes to such policies. The cost of such insurance policies shall be borne by the Seller. In the event a direct or indirect change of control of Seller or any consolidation, merger, dissolution or other similar sale event involving Seller occurs, Seller shall purchase tail insurance, on terms and conditions reasonably acceptable to Purchaser, covering each of the aforementioned policies through the end of all maintenance and warranty obligation periods.

Section 8.3 Survival of Representations and Warranties. All representations, warranties, covenants, and obligations in this Agreement, the Disclosure Schedules, the supplements to the Disclosure Schedules, and any certificate, document, or other writing delivered pursuant to this Agreement will survive the Closing and the consummation and performance of the transactions contemplated by this Agreement. No indemnification claim shall be made based on any breach of a representation or warranty in this Agreement more than eighteen (18) months after the Closing Date (the “Survival Period”), except with respect to: (i) the representations and warranties contained in Sections 4.9(b)—(f) (Environmental Laws) and 4.14 (Taxes) and any covenants contained in this Agreement with respect to Taxes, which shall survive until thirty (30) days following the expiration of the applicable statute of limitation (including any extension thereof); and (ii) Sections 4.2 and 6.2 (Authorization of Agreement), 4.3, first sentence (Title to Certain Purchased Assets), 4.4 and 6.3 (No Conflicts), 4.5 (Capitalization), 4.6 (Undisclosed Liabilities), 4.7 (Solvency) and 4.18 (Brokers), which shall survive indefinitely.

Section 8.4 Notice of Claims. A party seeking indemnity hereunder (the “Indemnitee”) will give, prior to the expiration of the Survival Period, the party from whom indemnity is sought hereunder (the “Indemnitor”) prompt written notice (hereinafter, the “Indemnification Notice”) of any demands, claims, actions or causes of action (collectively, “Claims”) asserted against the Indemnitee. An Indemnitee shall deliver to the Indemnitor any such Indemnification Notice promptly after receipt by the Indemnitee of notice of the circumstances giving rise to a claim for indemnification under this Agreement. An Indemnitee’s failure to give such timely notice or to furnish the Indemnitor with any relevant data and documents in connection with any Claim shall not constitute a defence (in whole or in part) for any Claim for indemnification by such party, except and only to the extent that such failure shall result in a material prejudice to the Indemnitor.

Section 8.5 Conditions of Indemnification of Third Party Claims. The obligations and liabilities of an Indemnitor under Section 8.1 or 8.2, as applicable, with respect to Losses resulting from Claims by persons not a party to this Agreement shall be subject to the following terms and conditions:

(a) Promptly after delivery of an Indemnification Notice in respect of a Claim and subject to paragraph (b) of this Section 8.5, the Indemnitor may elect, by written notice to the Indemnitee within ten (10) days of an Indemnification Notice, to undertake the investigation and defense thereof with counsel reasonably satisfactory to the Indemnitee, at the sole cost and expense of the Indemnitor. If the Indemnitor chooses to defend any Claim, the Indemnitee shall cooperate with all reasonable requests of the Indemnitor and shall make reasonably available to the Indemnitor any books, records or other non-confidential documents within its control that are required for such defense.

(b) In the event that the Indemnitor, within ten (10) days after receipt of an Indemnification Notice, does not so elect to defend such Claim, the Indemnitee will have the right to undertake the investigation and defense, of such Claim at the expense of the Indemnitor. The Indemnitee shall not settle or compromise any Claim, or consent to the entry of a judgment, whether or not the Indemnitor shall elect to defend such Claim, without the written consent of the Indemnitor.

Section 8.6 Limitation on Indemnity. No Indemnitor shall have any liability for indemnification pursuant to Section 8.1(b) of this Article VIII, unless or until the aggregate amount of Losses hereunder exceeds Twenty-Five Thousand Dollars ($25,000) (the “Basket”) and the maximum liability of the Purchaser Indemnitors for claims pursuant to Sections 8.1(b) shall not exceed $500,000. Notwithstanding the preceding, the Basket shall not apply and indemnification obligations under this Article VIII shall be unlimited in the event that Purchaser suffers Losses relating to or arising out of Special Matters and Losses relating to Taxes.

Section 8.7 Payment and Settlement of Amounts Due.

(a) Subject to Section 8.6, the amount of any Loss due from the Purchaser Indemnitors pursuant to any of the provisions of this Article VIII, together with any costs to which Purchaser may be entitled under the provisions hereof, if any, shall be paid in cash to

Purchaser by the Purchaser Indemnitors within thirty (30) days after the parties hereto have reached a mutual agreement, a court has rendered a final judgment or an arbitration panel has issued a final award.

(b) Subject to Section 8.6, the amount of any Loss due from Purchaser, pursuant to any of the provisions of this Article VIII, together with the costs to which the Seller may be entitled under the provisions hereof, if any, shall be paid in cash to the Seller by Purchaser within thirty (30) days after the parties hereto have reached a mutual agreement, a court has rendered a final judgment or an arbitration panel has issued a final award.

(c) The parties hereto agree that should an party not make full payment of any such obligations within such thirty (30) day period, any amount payable shall accrue interest from and including the date of agreement of the indemnifying party or final, non-appealable adjudication to and including the date such payment has been made at a rate per annum equal to 10% or the highest interest rate permitted by applicable Laws and Regulations, if lower. Such interest shall be calculated daily on the basis of a 365 day year and the actual number of days elapsed, without compounding..

Section 8.8 Assignment of Claims. Indemnitee shall assign to Indemnitor, for its use and benefit, any and all defenses, claims, causes of action and demands of whatever kind and nature which Indemnitee may have against any person, firm, corporation or entity which relate to the matter giving rise to a Loss for which indemnity is sought. Indemnitee agrees to reasonably cooperate in any efforts by Indemnitor to recover such Loss from any person, firm, corporation or entity.

Section 8.9 Method of Calculating Losses. In determining the amount of any Losses with respect to a breach of a representation or warranty, “materiality” and “Material Adverse Effect” qualifiers contained in any representation or warranty shall be disregarded. The right to indemnification, payment of Losses, or other remedy based on such representations, warranties, covenants, and obligations will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement on the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligation. The waiver of any condition based on the accuracy of any representation warranty, or other performance of or compliance with any covenant or obligation, will not affect the right to indemnification, payment of Losses, or other remedy based upon a breach of such representations, warranties, covenants and obligations.

Section 8.10 Tax Treatment of Indemnification Payments. Purchaser and Seller agree to treat any indemnification payment made pursuant to this Agreement as an adjustment to Purchase Price for all Tax purposes, unless otherwise required by applicable Law
