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.

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:

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.

(a)                                 For a period of three (3) years commencing on the Closing Date (the “Restricted Period”), Seller and Seller Parent shall not, and shall not permit any of its Affiliates to, directly or indirectly: (i) engage in or assist others in engaging in the Restricted Business in the Territory; (ii) have an equity ownership interest in any Person that engages directly or indirectly in the Restricted Business in the Territory in any capacity, including as a partner, shareholder, member, employee, principal, agent, trustee or consultant; (iii) solicit or accept the business of any actual or prospective client or customer of the Business (including any existing or former client or customer of a Seller and any Person that becomes a client or customer of the Business after the Closing), or any other Person who has a material business relationship with the Business, to purchase products or services similar to, or competitive with, the Business; or (iv) cause, induce

(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.

(c)                                  As of the Closing, Seller and Seller Parent shall remove all solar tracker product offerings from their websites.

27

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.

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.

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.

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.

Such interest shall be calculated daily on the basis of a 365 day year and the actual number of days elapsed, without compounding..

Section 8.9                     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 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.
