Each of the Company and each Subsidiary is duly qualified to conduct business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not have or reasonably be expected to result in a Material Adverse Effect and no proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or curtail such power and authority or qualification.

(c) Authorization; Enforcement. The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents and otherwise to carry out its obligations hereunder or thereunder. The execution and delivery of each of the Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby or thereby have been duly authorized by all necessary action on the part of the Company and no further consent or action is required by the Company other than the filing of the Certificate of Designations. Each of the Transaction Documents has been, or upon delivery will be, duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation, by-laws or other organizational or charter documents.

(d) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company, the issuance and sale of the Securities and the consummation by the Company of the other transactions contemplated thereby do not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of incorporation, articles of association, bylaws, or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any Lien upon any of the properties or assets of the Company or any Subsidiary, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected, or (iv) conflict with or violate the terms of any agreement by which the Company or any Subsidiary is bound or to which any property or asset of the Company or any Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not have or reasonably be expected to result in a Material Adverse Effect.

(e) Filings, Consents and Approvals. Neither the Company nor any Subsidiary is required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than the filing of the Certificate of Designations and required federal and state securities filings and such filings and approvals as are required to be made or obtained under the applicable Trading Market rules in connection with the transactions contemplated hereby, each of which has been, or (if not yet required to be filed) shall be, timely filed.

(f) Issuance of the Securities. The Securities are duly authorized and, when issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens. The Company has reserved from its duly authorized capital stock a number of shares of Common Stock and Preferred Stock for issuance of the Securities at least equal to the number of Securities which could be issued pursuant to the terms of the Transaction Documents, based on the then-anticipated exercise prices of the Warrant.

(g) Capitalization. Other than as set forth in Section 4.1(g) to the Disclosure Schedule, the capitalization of the Company is as described in the Company’s most recently filed periodic SEC Report as further qualified by any SEC Reports filed subsequent to the date thereof. Except with respect to equity participation rights of the holder of the Company’s Series D Preferred Stock all of which have been waived, no Person has any right of first refusal,

preemptive right, right of participation, or any similar right to participate in the transactions contemplated by the Transaction Documents. Except as a result of the purchase and sale of the Securities or as set forth in the SEC Reports or on Section 4.1(g) to the Disclosure Schedule, there are no outstanding options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or securities convertible into or exercisable for shares of Common Stock. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than Investor) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange, or reset price under such securities. All of the outstanding shares of capital stock of the Company are validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. No further approval or authorization of any stockholder, the Board of Directors of the Company or others is required for the issuance and sale of the Securities.

The Company has filed all required SEC Reports for the two years preceding the Effective Date (or such shorter period as the Company was required by law to file such SEC Reports) on a timely basis. As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Act and the Exchange Act and the rules and regulations of the SEC promulgated thereunder, as applicable, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with GAAP, except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.

Neither the Company nor any Subsidiary, nor to the knowledge of the Company any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. There has not been, and to the knowledge of the Company, there is not pending or contemplated, any investigation by the SEC involving the Company or any current or former director or officer of the Company. The SEC has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act or the Act.

(k) Labor Relations. No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the Company, which could reasonably be expected to result in a Material Adverse Effect.

(l) Compliance. Neither the Company nor any Subsidiary (i) is in default under or in violation of (and no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture, loan or credit agreement or any other similar agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) is in violation of any order of any court, arbitrator or governmental body, or (iii) is or has been in violation of any statute, rule or regulation of any governmental authority, including without limitation all foreign, federal, state and local laws applicable to its business, except in each case under clauses (i)-(iii) above as could not have a Material Adverse Effect.

(m) Regulatory Permits. The Company and each Subsidiary possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits could not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any Material Permit.

(n) Title to Assets. The Company and each Subsidiary have good and marketable title in fee simple to all real property owned by them that is material to the business of the Company and each Subsidiary and good and marketable title in all personal property owned by them that is material to the business of the Company and each Subsidiary, in each case free and clear of all Liens, except for Liens that do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and each Subsidiary and Liens for the payment of federal, state or other taxes, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and each Subsidiary are held by them under valid, subsisting and enforceable leases of which the Company and each Subsidiary are in compliance.

(o) Patents and Trademarks. The Company and each Subsidiary have, or have rights to use, all patents, patent applications, trademarks, trademark applications, service marks, trade names, copyrights, licenses and other similar rights that are necessary or material for use in connection with their respective businesses as described in the SEC Reports and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”). Neither the Company nor any Subsidiary has received a written notice that the Intellectual Property Rights used by the Company or any Subsidiary violates or infringes upon the rights of any Person. Except as set forth on Section 4.1(j) to the Disclosure Schedule, to the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights of the Company or each Subsidiary.

(p) Insurance. The Company and each Subsidiary are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and each Subsidiary are engaged, including but not limited to directors and officers insurance coverage at least equal to the Maximum Placement. To the best of Company’s knowledge, such insurance contracts and policies are accurate and complete. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a significant increase in cost.

(q) Transactions With Affiliates and Employees. Except as set forth in the SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case in excess of $120,000 other than (i) for payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) for other employee benefits, including stock option agreements under any equity incentive plan of the Company.

(r) Sarbanes-Oxley; Internal Accounting Controls. The Company is in material compliance with all provisions of the Sarbanes-Oxley Act of 2002, which are applicable to it as of the date of the Commitment Closing. The Company and each Subsidiary maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s most recently filed periodic report under the Exchange Act, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the date prior to the filing date of the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the Company’s disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal accounting controls or its disclosure controls and procedures or, to the Company’s knowledge, in other factors that could materially affect the Company’s internal accounting controls or its disclosure controls and procedures.

(s) Certain Fees. Except for the payment of the Commitment Fee or as set forth on Section 4.1(s) to the Disclosure Schedule, no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. Investor shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section 4.1(s) (including without limitation as set forth on Section 4.1(s) to the Disclosure Schedule) that may be due in connection with the transactions contemplated by this Agreement or the other Transaction Documents.

(t) Private Placement. Assuming the accuracy of Investor representations and warranties set forth in Section 4.2, no registration under the Act is required for the offer and sale of the Securities by the Company to Investor as contemplated hereby. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of any Trading Market.

(u) Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Securities, will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act.

(v) Registration Rights. No Person (other than Investor pursuant to the Transaction Documents) has any right to cause the Company to effect the registration under the Act of any securities of the Company.

(w) Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12 of the Exchange Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act nor has the Company received any notification that the SEC is contemplating terminating such registration. The Company has not, in the 12 months preceding the Effective Date, received notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all such listing and maintenance requirements.

(x) Application of Takeover Protections. The Company and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti takeover provision under the Company’s Certificate of Incorporation (or similar charter documents) or the laws of its state of incorporation that is or could become applicable to Investor as a result of Investor and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation the Company’s issuance of the Securities and Investor’s ownership of the Securities.

(y) Disclosure; Non-Public Information. Except with respect to the information that will be, and to the extent that it actually is timely publicly disclosed by the Company pursuant to Section 2.2(c)(i), and notwithstanding any other provision in this Agreement or the other Transaction Documents, neither the Company nor any other Person acting on its behalf has provided Investor or its agents or counsel with any information that constitutes or might constitute material, non-public information, including without limitation this Agreement and the Exhibits, Appendices and Schedules hereto, unless prior thereto Investor shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that neither Investor nor any Affiliate of Investor shall have any duty of trust or confidence that is owed directly, indirectly, or derivatively to the Company or the shareholders of the Company or to any other Person who is the source of material non-public information regarding the Company. No information contained in the Disclosure Schedules constitutes material non-public information. There is no adverse material information regarding the Company that has not been publicly disclosed prior to the Effective Date. The Company understands and confirms that Investor will rely on the foregoing representations and covenants in effecting transactions in securities of the Company. All disclosure provided to Investor regarding the Company, its business and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, furnished by or on behalf of the Company with respect to the representations and warranties made herein are true and correct in all material respects and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

(z) No Integrated Offering. Neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Act or which could violate any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of the Trading Market.

As set forth in the SEC Reports, the Company anticipates that all cash resources will be expended by early in the first quarter of 2011 and, if unable to raise additional financing, the Company may be required to: (1) reduce spending plans, (2) license products or technologies that the Company would otherwise seek to commercialize to third parties, and/or (3) sell certain assets. In connection with the transactions contemplated by the Transaction Documents: (i) the Company has paid undisputed debts as they matured for at least one year prior to the Effective Date, (ii) the Company will not be rendered insolvent by such transactions, (iii) after giving effect to such transactions, the Company will be able to pay its short term debts as they mature, (iv) such transactions will not cause the Company to be left with unreasonably small capital for the business in which it is engaged and proposes to be engaged, (v) the Company did not and does not have any intent to hinder, delay, or defraud any of its creditors, (vi) the Company has a valid business reason for entering into such transactions, and (vii) the Company is receiving new value and consideration therefor constituting reasonably equivalent value and fair market value consideration.

There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. The Company has not executed a waiver with respect to the statute of limitations relating to the assessment or collection of any foreign, federal, statue or local tax. None of the Company’s tax returns is presently being audited by any taxing authority.

The Company acknowledges and agrees that Investor is acting solely in the capacity of arm’s length purchaser with respect to this Agreement and the transactions contemplated hereby. The Company further acknowledges that Investor is not acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any statement made by Investor or any of its representatives or agents in connection with this Agreement and the transactions contemplated hereby is not advice or a recommendation and is merely incidental to Investor’s purchase of the Securities.

(ii) Section 5 Compliance. No representation or warranty or other statement made by Company in the Transaction Documents contains any untrue statement or omits to state a material fact necessary to make any of them, in light of the circumstances in which it was made, not misleading.

ARTICLE 5

OTHER AGREEMENTS OF THE PARTIES

5.1 Transfer Restrictions

(a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than (i) pursuant to an effective Registration Statement or Rule 144, (ii) to the Company, (iii) to an Affiliate of Investor, or (iv) in connection with a pledge as contemplated in Section 5.1(b), the Company may require the transferor thereof to provide to the Company an opinion of Luce Forward Hamilton & Scripps LLP (“Luce Forward”), or other counsel selected by the transferor and reasonably acceptable to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Act.

(b) Investor agrees to the imprinting, so long as is required by this Section 5.1, of the following legend, or substantially similar legend, on any certificate evidencing Securities other than DWAC Shares:

NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

The Company agrees to cause such legend to be removed immediately upon effectiveness of a Registration Statement, or when any Common Shares are eligible for sale under Rule 144 and, if requested by Investor or the transfer agent, to promptly provide at the Company’s expense a legal opinion of counsel to the Company confirming that such legend may be removed. Company further acknowledges and agrees that Investor may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Act and who agrees to be bound by the provisions of this Agreement and, if required under the terms of such arrangement, Investor may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At Investor’s reasonable expense, the Company will execute and deliver such documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities.

5.2 Furnishing of Information. As long as Investor owns Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the Effective Date pursuant to the Exchange Act. Upon the request of Investor, the Company shall deliver to Investor a written certification of a duly authorized officer as to whether it has complied with the preceding sentence. As long as Investor owns Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to Investor and make publicly available in accordance with Rule 144(c) such information as is required for Investor to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell such Securities without registration under the Act within the limitation of the exemptions provided by Rule 144.

5.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Act of the sale of the Securities to Investor or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

5.4 Securities Laws Disclosure; Publicity. The Company and Investor shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby, and neither the Company nor Investor shall issue any such press release or otherwise make any such public statement without the prior consent of the Company, with respect to any such press release of Investor, or without the prior consent of Investor, with respect to any such press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law or Trading Market regulations, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of Investor, or include the name of Investor in any filing with the SEC or any regulatory agency or Trading Market, without the prior written consent of Investor, except (i) as contained in the Current Report on Form 8-K and press release filed pursuant to the Original Agreement, (ii) as required by federal securities law in connection with any registration statement under which the Common Shares are registered, (iii) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide Investor with prior notice of such disclosure, or (iv) to the extent such disclosure is required in any SEC Report filed by the Company.

5.5 Shareholders Rights Plan. No claim will be made or enforced by the Company or, to the knowledge of the Company, any other Person that Investor is an “Acquiring Person” under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that Investor could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and Investor. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended.

5.6 Non-Public Information. The Company covenants and agrees that neither it nor any other Person acting on its behalf will provide Investor or its agents or counsel with any information that the Company believes or reasonably should believe constitutes material non-public information, unless prior thereto Investor shall have executed a written agreement regarding the confidentiality and use of such information. On and after the Effective Date, except as may be set forth in a written and executed confidentiality agreement, neither Investor nor any Affiliate Investor shall have any duty of trust or confidence that is owed directly, indirectly, or derivatively, to the Company or the shareholders of the Company, or to any other Person who is the source of material non-public information regarding the Company. The Company understands and confirms that Investor shall be relying on the foregoing in effecting transactions in securities of the Company.

5.7 Reimbursement. If Investor becomes involved in any capacity in any proceeding by or against any Person who is a stockholder of the Company (except as a result of sales, pledges, margin sales and similar transactions by Investor to or with any current stockholder), solely as a result of Investor’s acquisition of the Securities under this Agreement, the Company will reimburse Investor for its reasonable legal and other reasonable expenses (including the reasonable cost of any investigation preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred, or will assume the defense of Investor in such matter. The reimbursement obligations of the Company under this Section 5.7 shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of Investor who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of Investor and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, Investor and any such Affiliate and any such Person. The Company also agrees that neither Investor nor any such Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company solely as a result of acquiring the Securities under this Agreement.

5.8 Indemnification of Investor

(a) Company Indemnification Obligation. Subject to the provisions of this Section 5.8, the Company will indemnify and hold Investor and any Warrant holder, their Affiliates and attorneys, and each of their directors, officers, shareholders, partners, employees, agents, and any person who controls Investor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “Investor Parties” and each an “Investor Party”), harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, reasonable costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation (collectively, “Losses”) that any Investor Party may suffer or incur as a result of or relating to (i) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents, (ii) any action instituted against any Investor Party, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate

of an Investor Party, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of Investor’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings Investor may have with any such stockholder or any violations by Investor of state or federal securities laws or any conduct by Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance), (iii) any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement (or in a Registration Statement as amended by any post-effective amendment thereof by the Company), or arising out of or based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and/or (iv) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (or any amendments or supplements to any Prospectus), in any free writing prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company, or in any Prospectus together with any combination of one or more of the free writing prospectuses, if any, or arising out of or based upon any omission or alleged omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(b) Indemnification Procedures. If any action shall be brought against an Investor Party in respect of which indemnity may be sought pursuant to this Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing. The Investor Parties shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Investor Parties except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict with respect to the dispute in question on any material issue between the position of the Company and the position of the Investor Parties such that it would be inappropriate for one counsel to represent the Company and the Investor Parties. The Company will not be liable to the Investor Parties under this Agreement (i) for any settlement by an Investor Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is either attributable to Investor’s breach of any of the representations, warranties, covenants or agreements made by Investor in this Agreement or in the other Transaction Documents.

5.9 Reservation of Securities. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may be required to fulfill its obligations in full under the Transaction Documents.

5.10 Limited Standstill. The Company will deliver to Investor on or before each Tranche Closing Date, and will honor and enforce, and will take reasonable actions to assist Investor in enforcing, the provisions of, the Lock-Up Agreements with the Company’s officers, directors and beneficial owners of 10% or more of the Common Stock.

5.11 Prospectus Availability and Changes. The Company will make available to Investor upon request, and thereafter from time to time will furnish Investor, as many copies of

any Prospectus (or of the Prospectus as amended or supplemented if the Company shall have made any amendments or supplements thereto after the effective date of the applicable Registration Statement) as Investor may request for the purposes contemplated by the Act; and in case Investor is required to deliver a prospectus after the nine-month period referred to in Section 10(a)(3) of the Act in connection with the sale of the Common Shares, or after the time a post-effective amendment to the applicable Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Act, the Company will prepare, at its expense, promptly upon request such amendment or amendments to the Registration Statement and the Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be. The Company will advise Investor promptly of the happening of any event within the time during which a Prospectus is required to be delivered under the Act which could require the making of any change in the Prospectus then being used so that the Prospectus would not include an untrue statement of material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading, and to advise Investor promptly if, during such period, it shall become necessary to amend or supplement any Prospectus to cause such Prospectus to comply with the requirements of the Act, and in each case, during such time, to prepare and furnish, at the Company’s expense, to Investor promptly such amendments or supplements to such Prospectus as may be necessary to reflect any such change or to effect such compliance. The Company shall have no obligation to separately advise Investor of, or deliver copies to Investor of, the SEC Reports, all of which Investor shall be deemed to have notice of.

5.12 Required Approval. No transactions contemplated under this Agreement or the Transaction Documents shall be consummated for an amount that would require approval by any Trading Market or Company stockholders under any approval provisions, rules or regulations of any Trading Market applicable to the Company, unless and until such approval is obtained. Company shall use best efforts to obtain any required approval as soon as possible.

5.13 Activity Restrictions. For so long as Investor or any of its Affiliates holds any Preferred Shares, Commitment Fee Shares, Warrant, Warrant Shares, or DWAC Shares, neither Investor nor any Affiliate will: (i) vote any shares of Common Stock owned or controlled by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions, plans or proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in Investor and/or its Affiliates exceeding the Investor Ownership Limit, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its subsidiaries, (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure, including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940, (g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h)

causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees, agents or representatives to amend or waive any provision of this Section 5.13.

5.14 Registration Statements and Prospectuses.

(a) The Company will use its best efforts to file within 45 (forty-five) calendar days after the Effective Date (or as soon as possible thereafter), to cause to become effective as soon as possible thereafter, and to remain effective until all Common Shares have been sold or are Rule 144 Eligible, a Registration Statement for the resale of all Common Shares issued or issuable hereunder including without limitation all Warrant Shares underlying the Warrant or such lesser number of Common Shares permitted to be registered pursuant to SEC Guidance. Each Registration Statement shall comply when it becomes effective, and, as amended or supplemented, at the time of any Tranche Notice Date, Tranche Closing Date, or issuance of any Common Shares, and at all times during which a prospectus is required by the Act to be delivered in connection with any sale of Common Shares, will comply, in all material respects, with the requirements of the Act.

(b) Each Registration Statement, as of its respective effective time, will not, as applicable, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(c) Each Prospectus will comply, as of its date and the date it will be filed with the SEC, and, at the time of any Tranche Notice Date, Tranche Closing Date, or issuance of any Common Shares, and at all times during which a prospectus is required by the Act to be delivered in connection with any sale of Common Shares, will comply, in all material respects, with the requirements of the Act.

(d) At no time during the period that begins on the date a Prospectus is filed with the SEC and ends at the time a Prospectus is no longer required by the Act to be delivered in connection with any sale of Common Shares will any such Prospectus, as then amended or supplemented, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(e) Each Registration Statement will meet, and the offering and sale of the Common Shares as contemplated hereby will comply with, the requirements of Rule 415 under the Act.

(f) The Company will not, directly or indirectly, use or refer to any “free writing prospectus” (as defined in Rule 405 under the Act) except in compliance with Rules 164 and 433 under the Act.

(g) The Company will not be an “ineligible issuer” (as defined in Rule 405 under the Act) as of the eligibility determination date for purposes of Rules 164 and 433 under the Act with respect to the offering of the Common Shares contemplated by any Registration Statement that is filed, without taking into account any determination by the SEC pursuant to Rule 405 under the Act that it is not necessary under the circumstances that the Company be considered an “ineligible issuer.”

(h) If (i) there is material non-public information regarding the Company which the Company’s Board of Directors reasonably determines not to be in the Company’s best interest to disclose and which the Company is not otherwise required to disclose and which the Company would be required to disclose under the Registration Statement, or (ii) there is a significant business opportunity (including, but not limited to, the acquisition or disposition of assets other than in the ordinary course of business or any merger, consolidation, tender offer or other similar transaction) available to the Company which the Board of Directors reasonably determines not to be in the Company’s best interest to disclose and which the Company would be required to disclose under the Registration Statement, and in the case of either (i) or (ii) the Company reasonably believes it is required under SEC Guidance to postpone or suspend filing or effectiveness of the Registration Statement, the Company shall immediately notify Investor in writing that the Registration Statement may not be used in connection with any sales of the Company’s securities for a period not to exceed 10 consecutive days (a “Blackout Period”), provided that the aggregate of all Blackout Periods may not exceed 30 days during any 12 month period. During a Blackout Period, the Company shall not be permitted to deliver any Tranche Notices or effect any Tranche Closings.

5.15 Investor Due Diligence. Investor shall have the right and opportunity to conduct due diligence, at its own expense, with respect to any Registration Statement or Prospectus in which the name of Investor or any Affiliate of Investor appears.

5.16 Commitment Fee Shares. On the date that any of the Commitment Fee Shares first become Rule 144 Eligible, the Company shall cause all restrictive legends to be removed from the stock certificate(s) evidencing such Commitment Fee Shares, including without limitation causing the Company’s legal counsel to issue any necessary opinions to the Transfer Agent, and such Commitment Fee Shares shall be delivered to Investor or its designee as DWAC Shares on the date that such shares become Rule 144 Eligible.

5.17 Registration. In the event that all Common Shares that Company is required to make available to Investor, including as Warrant Shares upon the exercise of Warrants, are not, by the one year anniversary of the Effective Date, made available to Investor as DWAC Shares without restriction on resale pursuant to (i) an effective Registration Statement (with the number of Warrant Shares included therein subject to the limitation set forth in Section 5.14(a) hereof), or (ii) Rule 144 without requiring discharge by payment in full of any notes given in exchange for any Warrant Shares prior to the sale thereof or limiting the amount of securities that may be sold, Company shall, at Investor’s election in Investor’s sole discretion, exercise the Company’s Redemption Option provided for in Section 6 of the Certificate of Designations to effectuate the repurchase of any outstanding Preferred Shares.

No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the Company and Investor or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

6.4 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof

6.5 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. Neither the Company nor Investor may assign this Agreement.

6.6 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 5.8.

6.7 Governing Law; Dispute Resolution. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the laws of the State of New York, without regard to the principles of conflicts of law that would require or permit the application of the laws of any other jurisdiction. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The parties hereby waive all rights to a trial by jury.

6.8 Survival. The representations and warranties contained herein shall survive the Closing and the delivery and exercise of the Securities.

6.9 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or in a PDF by e-mail transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

6.10 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.11 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.

6.12 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of Investor and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. Neither the Company nor Investor shall be liable for special, indirect, consequential or punitive damages suffered or alleged to be suffered by the other party or any third party, whether arising from or related to the Transaction Documents or otherwise.

6.13 Payment Set Aside. To the extent that the Company makes a payment or payments to Investor pursuant to any Transaction Document or Investor enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.14 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been cancelled.

6.15 Time of the Essence. Time is of the essence with respect to all provisions of this Agreement that specify a time for performance.

6.16 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any

amendments hereto. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

6.17 Entire Agreement. This Agreement, together with the Exhibits, Appendices and Schedules hereto, contains the entire agreement and understanding of the parties, and supersedes all prior and contemporaneous agreements, term sheets, letters, discussions, communications and understandings, both oral and written, which the parties acknowledge have been merged into this Agreement. No party, representative, attorney or agent has relied upon any collateral contract, agreement, assurance, promise, understanding or representation not expressly set forth hereinabove. The parties hereby expressly waive all rights and remedies, at law and in equity, directly or indirectly arising out of or relating to, or which may arise as a result of, any Person’s reliance on any such assurance.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized signatories as of the date first indicated above.

ENTECH SOLAR, INC.

AMENDED AND RESTATED

WARRANT TO PURCHASE COMMON STOCK


Warrant No.: 2010-1		Issuance Date: November [ ], 2010

Number of Warrant Shares: $[ ]

Exercise Price: $0.[ ] per share

Entech Solar, Inc., a Delaware corporation (“Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Socius CG II, Ltd., a Bermuda exempted company, the holder hereof, or its designees or assigns (“Holder”), is obligated, subject to the terms set forth herein, to purchase from the Company, at the Exercise Price set forth herein, upon automatic exercise of this Amended and Restated Warrant to Purchase Common Stock (including any warrant issued in exchange, transfer or replacement hereof, the “Warrant”), subject to acceleration pursuant to Section 3.3 hereof, that number of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock set forth above and as adjusted herein (the “Warrant Shares”).

This Warrant is issued pursuant to the Amended and Restated Preferred Stock Purchase Agreement dated November [ ], 2010, by and among the Company and the investor referred to therein (the “Purchase Agreement”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in ARTICLE 13 hereof.

This Warrant fully amends and restates the Warrant to Purchase Common Stock issued by the Company to Holder dated February 19, 2010 (the “Prior Warrant”), which such Prior Warrant shall be surrendered to the Company by the Holder for cancellation and is hereby cancelled and voided in its entirety ab initio.

This Warrant shall consist of and be exercisable in tranches (each, a “Warrant Tranche”), with a separate tranche being created upon each delivery of a Tranche Notice under the Purchase Agreement. Each Warrant Tranche will obligate the Holder to exercise the Warrant and purchase a number of shares of Common Stock with an Aggregate Exercise Price equal to 135% of the Tranche Purchase Price for the applicable Tranche Notice. Attached to this Warrant is a schedule (the “Warrant Exercise Schedule”) that sets forth the issuance date, the number of Warrant Shares, and the Exercise Price for each Warrant Tranche. The Warrant Exercise Schedule shall be updated by the Company, with an updated copy provided to the Holder, promptly following each exercise of this Warrant. Notwithstanding anything to the contrary in this Warrant, no portion of this Warrant shall vest or be exercisable except under the Warrant Tranches (the “Tranche Limitation”).

In no event shall the Company be permitted to deliver a Tranche Notice if the number of registered shares underlying this Warrant is insufficient to cover the portion of the Warrant that will vest and become automatically exercisable in connection with such Tranche Notice. If the number of registered shares underlying this Warrant is or becomes insufficient to permit the Company to issue registered shares upon exercise of this Warrant, the Company shall promptly amend the Registration Statement to include more shares thereunder, with such amendment to be filed sufficiently in advance of the date the Company intends to deliver a Tranche Notice so as to ensure that registered shares are available to Holder on the Tranche Notice Date.

ARTICLE 1

EXERCISE OF WARRANT.

1.1 Mechanics of Exercise.

1.1.1 Subject to the terms and conditions hereof (including without limitation the Tranche Limitation), this Warrant shall be automatically exercised by the Holder on each Tranche Notice Date, with such exercise documented by (i) delivery by Holder of a written notice to the Company, in the form attached hereto as Appendix 1 (the “Exercise Notice”), of the exercise of this Warrant, and (ii) payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”), with such payment made, at Holder’s option, (x) in cash or by wire transfer of immediately available funds, (y) by the issuance and delivery of a recourse promissory note substantially in the form attached hereto as Appendix 2 (each, a “Recourse Note”), or (z) if applicable, by cashless exercise pursuant to Section 1.3.

1.1.2 The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.

1.1.3 On the Trading Day on which the Company has received each of the Exercise Notice and the Aggregate Exercise Price (the “Exercise Delivery Documents”) from the

Holder by 6:30 p.m. Eastern time, or on the next Trading Day if the Exercise Delivery Documents are received after 6:30 p.m. Eastern time or on a non-Trading Day (in each case, the “Exercise Delivery Date”), the Company shall transmit (i) a facsimile acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the Holder, and (ii) an electronic copy of its share issuance instructions to the Holder and to the Company’s transfer agent (the “Transfer Agent”), with such transmissions to comply with the notice provisions contained in Section 6.2 of the Purchase Agreement, and shall instruct and authorize the Transfer Agent to credit such aggregate number of freely-tradable Warrant Shares to which the Holder is entitled to receive upon such exercise to the Holder’s or its designee’s balance account with The Depository Trust Company (DTC) through the Fast Automated Securities Transfer (FAST) Program through its Deposit Withdrawal Agent Commission (DWAC) system, with such credit to occur no later than 12:00 p.m. Eastern Time on the Trading Day following the Exercise Delivery Date, time being of the essence; provided, however, that if any Warrant Shares issuable in connection with the Company’s delivery of a Tranche Notice are not credited as DWAC Shares by 12:00 p.m. Eastern Time on the Trading Day following the Tranche Notice Date, then the Tranche Closing Date applicable to the Exercise Notice shall be extended by one Trading Day for each Trading Day that timely credit of DWAC Shares is not made.

1.1.4 Upon automatic exercise of the Warrant, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account.

1.1.5 If this Warrant is exercised and the number of Warrant Shares represented by this Warrant is greater than the number of Warrant Shares being acquired upon such exercise, then the Company shall, as soon as practicable and in no event later than one Trading Day after such exercise, update the Warrant Exercise Schedule to reflect the revised number of Warrant Shares for which this Warrant is then exercisable and deliver a copy of the updated Warrant Exercise Schedule to the Holder. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant, other than income-related taxes payable by the Holder.

1.2 Adjustments to Exercise Price and Number of Shares. In addition to other adjustments specified herein, the Exercise Price of this Warrant and the number of shares of Common Stock issuable upon exercise shall be adjusted as follows:

1.2.1 Exercise Price. The “Exercise Price” per share of Common Stock underlying this Warrant, subject to further adjustment as provided herein, shall be as follows: (i) with respect to the Warrant issued on the Effective Date and until the first Tranche Notice Date, the amount per Warrant Share set forth on the face of this Warrant, which is equal to Closing Bid Price for the Common Stock on the Trading Day prior to the Effective Date, and (ii) with respect to the portion of this Warrant that becomes exercisable on any Tranche Notice Date (including the first Tranche Notice Date), an amount per Warrant Share equal to the Closing Bid Price of a share of Common Stock on the Trading Day immediately preceding such Tranche Notice Date.

1.2.2 Number of Shares. Subject to the Tranche Limitation, the number of Warrant Shares underlying this Warrant and each Warrant Tranche, subject to further adjustment as provided herein, shall be as follows: (i) with respect to the portion of this Warrant as issued on the Effective Date and until the first Tranche Notice Date, the number of shares set forth on the face of this Warrant, which shall be that number of shares of Common Stock equal to the Maximum Placement multiplied by 135%, with the resulting sum divided by the Closing Bid Price of a share of Common Stock on the Trading Day prior to the Effective Date, and (ii) with respect to the portion of this Warrant that become exercisable on any Tranche Notice Date including the first Tranche Notice Date, a number of shares equal to the Tranche Purchase Price set forth in the applicable Tranche Notice multiplied by 135%, with the resulting sum divided by the Closing Bid Price of a share of Common Stock on the Tranche Notice Date. For example, if the Tranche Purchase Price is $1,000,000 and the Closing Bid Price is $0.50, then the number of Warrant Shares underlying that Warrant Tranche shall be $1,000,000 x 135% = $1,350,000 divided by $0.50 = 2,700,000 shares of Common Stock. On each Tranche Notice Date, the number of Warrant Shares underlying the related Warrant Tranche shall vest and be automatically exercised, and the aggregate number of Warrant Shares underlying this Warrant that are currently exercisable shall automatically adjust up or down to account for the change in the number of Warrant Shares covered by the new Warrant Tranche and for any Warrant Shares issued upon any prior or simultaneous exercise of this Warrant. If at any time the Holder reasonably believes that the number of Warrant Shares included in the Registration Statement is not sufficient to cover all exercises under this Warrant, then the Company shall amend such Registration Statement to include the additional number of Warrant Shares that may be required to provide such coverage.

1.3 Cashless Exercise. Notwithstanding anything contained herein to the contrary, if at any time there is not a current, valid and effective registration statement covering the Warrant Shares that are the subject of the Exercise Notice (the “Unavailable Warrant Shares”), the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):


Net Number =		(B-C) x A
		B

For purposes of the foregoing formula:

A = the total number of shares with respect to which this Warrant is then being exercised.

B = the average of the Closing Bid Prices of the shares of Common Stock (as reported by Bloomberg) for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the Exercise Notice.

C = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

1.4 Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason to credit to the Holder’s balance account with DTC, by 12:00 p.m. Eastern time on the Trading Day following the Tranche Notice Date, the number of shares of Common Stock to which the Holder is entitled upon automatic exercise of this Warrant, then, in addition to all other remedies available to the Holder, the Company shall pay in cash to the Holder on each day after such Trading Day that the issuance of such shares of Common Stock is not timely effected an amount equal to 1.5% of the product of (A) the sum of the number of shares of Common Stock not issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding the last possible date which the Company could have issued such shares of Common Stock to the Holder without violating Section 1.1. In addition to the foregoing, if after the Company’s issuance of a Tranche Notice the Company shall fail to timely (pursuant to Section 1.1.3 hereof) credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the automatic exercise of the applicable portion of this Warrant, and the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company, then the Company shall, within one Trading Day after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to credit such Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise hereunder and to issue such Warrant Shares shall terminate, or (ii) promptly honor its obligation to credit such Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise hereunder and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock sold by Holder in satisfaction of its obligations, times (B) the Closing Bid Price on the date of exercise.

1.5 Exercise Limitation. Notwithstanding any other provision, at no time may the Company deliver a Tranche Notice if such delivery would trigger either: (a) exercise of this Warrant such that the number of Warrant Shares to be received pursuant to such exercise exceeds 135.0% of the aggregate of all Tranche Purchase Prices under and in connection with all Tranche Notices delivered pursuant to the Purchase Agreement prior to the date of exercise; or (b) exercise of this Warrant such that the number of Warrant Shares to be received pursuant to such exercise, aggregated with all other shares of Common Stock or other voting securities of the Company then owned or deemed beneficially owned by the Holder and its affiliates, would result

in the Holder and its affiliates owning or being deemed to beneficially own more than 9.99% of the Common Stock or other voting securities of the Company as would be outstanding on the date of exercise, with such ownership percentage determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (the “Holder Ownership Limit”). In addition, as of any date, the aggregate number of shares of Common Stock into which this Warrant is exercisable within 61 days, together with all other shares of Common Stock or other voting securities of the Company then owned or deemed beneficially owned by Holder and its affiliates, shall not exceed the Holder Ownership Limit.

1.6 Activity Restrictions. For so long as Holder or any of its affiliates holds this Warrant or any Warrant Shares, neither Holder nor any affiliate will: (i) vote any shares of Common Stock owned or controlled by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions, plans or proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in Holder and/or its affiliates exceeding the Holder Ownership Limit, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its subsidiaries, (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure, including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940, (g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees, agents or representatives to amend or waive any provision of this Section 1.6.

1.7 Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12.

1.8 Insufficient Authorized Shares. If at any time while any portion of this Warrant remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal to 110% of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise

of the portion of the Warrant then outstanding (the “Required Reserve Amount”) (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the portion of the Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 90 days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

ARTICLE 2

ADJUSTMENT UPON SUBDIVISION OR COMBINATION OF COMMON STOCK

If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any adjustment under this ARTICLE 2 shall become effective at the close of business on the date the subdivision or combination becomes effective.

ARTICLE 3

PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS

3.1 Purchase Rights. In addition to any adjustments pursuant to ARTICLE 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

3.2 Subsequent Equity Sales. In addition to any adjustments made pursuant to ARTICLE 2 above, if the Company or any Subsidiary thereof, as applicable, at any time subsequent to the first Tranche Closing Date while this Warrant is outstanding, shall sell or grant

any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents entitling any Person other than the Holder to acquire shares of Common Stock, at an effective price per share less than the then Exercise Price (such lower price, the “Base Share Price” and such issuances, collectively, a “Dilutive Issuance”), then the Exercise Price shall be reduced and only reduced to equal the Base Share Price and the number of Warrant Shares issuable hereunder shall be increased such that the aggregate Exercise Price payable hereunder, after taking into account the decrease in the Exercise Price, shall be equal to the aggregate Exercise Price prior to such adjustment. Except as otherwise provided herein, such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. If the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share which is less than the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance, provided, however, that such date of the Dilutive Issuance is after the first Tranche Closing Date. Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 3.2 in respect of an Exempt Issuance, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock, or securities issued under employee benefit plans, that occur after the date of the Purchase Agreement. The Company shall notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 3.2, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 3.2, upon the occurrence of any Dilutive Issuance, after the date of such Dilutive Issuance the Holder is entitled to receive a number of Warrant Shares based upon the Base Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise.

3.3 Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 3.3 pursuant to written agreements in form and substance satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each Holder of this Warrant in exchange for such Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an adjusted exercise price equal to the value for the shares of Common Stock reflected by the terms of such Fundamental Transaction, and exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall

succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) purchasable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Warrant been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) purchasable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Warrant been exercised immediately prior to such Fundamental Transaction; provided, however, that in the event the Fundamental Transaction involves the issuance of cash or freely tradable securities by an issuer listed on the New York Stock Exchange or the Nasdaq Stock Market, then the ability to exercise this Warrant shall expire on the consummation of that Fundamental Transaction. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section 3.3 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied without regard to any limitations on the exercise of this Warrant.

3.4 Notwithstanding the foregoing Section 3.3, in the event of a Fundamental Transaction (other than one in which the Successor Entity is (i) The Quercus Trust or an Affiliate thereof, or (ii) a Public Successor Entity that assumes this Warrant such that this Warrant shall be exercisable for the publicly traded common stock of such Public Successor Entity), at the request of the Holder delivered before the 90th day after the effective date of such Fundamental Transaction, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Trading Days after such request (or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the value of the remaining unexercised portion of this Warrant on the date of such consummation, which value shall be determined by use of the Black Scholes Option Pricing Model using a volatility equal to the 100 day average historical price volatility prior to the date of the public announcement of such Fundamental Transaction.

ARTICLE 4

NONCIRCUMVENTION

The Company hereby covenants and agrees that the Company will not, by amendment of its certificate or articles of incorporation, articles of association, bylaws, or any other organization documents, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any portion of this Warrant remains outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of this Warrant, 110% of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of this Warrant then outstanding (without regard to any limitations on exercise).

ARTICLE 5

WARRANT HOLDER NOT DEEMED A STOCKHOLDER

Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this ARTICLE 5, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

ARTICLE 6

REISSUANCE OF WARRANTS

6.1 Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 6.4), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less then the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 6.4) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

6.2 Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 6.4) representing the right to purchase the Warrant Shares then underlying this Warrant.

6.3 Exchangeable for Multiple Warrant. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 6.4) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Warrant for fractional shares of Common Stock shall be given.

6.4 Issuance of New Warrant. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 6.1 or Section 6.3, the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrant issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

ARTICLE 7

NOTICES

Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 6.2 of the Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a description of such action and the reason

therefore. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon any adjustment of the Exercise Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock as such or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder.

ARTICLE 8

AMENDMENT AND WAIVER

Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Required Holders; provided that except as set forth in this Warrant no such action may increase the exercise price of any Warrant or decrease the number of shares or class of stock obtainable upon exercise of any Warrant without the written consent of the Holder. No such amendment shall be effective to the extent that it applies to less than all of the holders of this Warrant.

ARTICLE 9

GOVERNING LAW

This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

ARTICLE 10

CONSTRUCTION; HEADINGS

This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant.

ARTICLE 11

DISPUTE RESOLUTION

In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or

arithmetic calculations via facsimile within 2 Trading Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three Trading Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within 2 Trading Days submit via facsimile (a) the disputed determination of the Exercise Price or arithmetic calculation to an independent, reputable investment bank or independent registered public accounting firm selected by Holder subject to Company’s approval, which may not be unreasonably withheld or delayed, or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent registered public accounting firm. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than 3 Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

ARTICLE 12

REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF

The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder right to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

ARTICLE 13

FORM OF NOTE

SECURED PROMISSORY NOTE


$[ ]		Date: [ ], 20[ ]

FOR VALUE RECEIVED, Socius CG II, Ltd. (“Borrower”) promises to pay to the order of Entech Solar, Inc. (“Lender”), at 13301 Park Vista Boulevard, Suite 100, Fort Worth, Texas 76177, or at such other place as Lender may from time to time designate in writing, the principal sum of set forth above, with interest, as follows:

1. Interest. The principal balance outstanding from time to time under this Secured Promissory Note (this “Note”), shall bear interest from and after the date hereof at the rate of 2.0% per year. Interest shall be calculated on a simple interest basis and the number of days elapsed during the period for which interest is being calculated. Payments of interest will be due on each annual anniversary of the date of this Note; provided that Borrower will not be in default hereunder for failure to make any annual interest payment when due (other than on the Maturity Date) and the amount of interest not paid when due shall be added to the principal balance of this Note and such amount will thereafter accrue interest at the rate set forth above.

2. Payments. If not sooner paid, the entire unpaid principal balance, interest thereon and any other charges due and payable under this Note shall be due and payable on the fourth anniversary of the date of this Note (“Maturity Date”); provided, however, that no payments on this Note will be due or payable so long as either (a) Lender is in default under any preferred stock purchase agreement for Series G Preferred Stock with Borrower or any Warrant issued pursuant thereto, any loan agreement or other material agreement entered into with Borrower, or (b) there are any shares of Series G Preferred Stock of Lender issued or outstanding (each, a “Non-Payment Event”). Upon the termination or cure of any Non-Payment Event, Borrower’s obligation to pay amounts outstanding on this Note will immediately be reinstated. Borrower shall have the right to prepay all or any part of the principal balance of this Note at any time without penalty or premium. Notwithstanding the foregoing, in the event that Lender redeems all or a portion of any shares of Series G Preferred Stock then held by Borrower, the proceeds of any such redemption will be applied by Borrower to pay down the accrued interest and outstanding principal of this Note and Lender will be permitted to offset the full amount of such proceeds against amounts outstanding under this Note. All payments on this Note shall be first applied to interest, then to reduce the outstanding principal balance hereof.

3. Full Recourse Note. THIS IS A FULL RECOURSE PROMISSORY NOTE. Accordingly, notwithstanding that Borrower’s obligations under this Note are secured by the Collateral, in the event of a material default hereunder, Lender shall have full recourse to all the other assets of Borrower. Moreover, Lender shall not be required to proceed against or exhaust any Collateral, or to pursue any Collateral in any particular order, before Lender pursues any other remedies against Borrower or against any of Borrower’s assets.

4. Security

a. Pledge. As security for the due and prompt payment and performance of all payment obligations under this Note and any modifications, replacements and extensions

hereof (collectively, “Secured Obligations”), Borrower hereby pledges and grants a security interest to Lender in all of Borrower’s right, title, and interest in and to all of the following, now owned or hereafter acquired or arising (together the “Collateral”):

i. Freely tradable shares of common stock, shares of preferred stock, bonds, notes and/or debentures (collectively, “Pledged Securities”) with a collective fair market value on the date hereof at least equal to the principal amount of this Note, based upon the trading price of such securities on the OTC Bulletin Board, NASDAQ Capital Market, NASDAQ Global Market, NASDAQ Global Select Market, NYSE Amex, or New York Stock Exchange;

ii. all rights of Borrower with respect to or arising out of the Pledged Securities, including voting rights, and all equity and debt securities and other property distributed or distributable with respect thereto as a result of merger, consolidation, dissolution, reorganization, recapitalization, stock split, stock dividend, reclassification, exchange, redemption, or other change in capital structure; and

iii. all proceeds, replacements, substitutions, accessions and increases in any of the Collateral.

b. Replacement Securities. So long as any Secured Obligations remain outstanding, in the event that Borrower sells or disposes of any Pledged Securities, Borrower shall promptly provide replacement securities of equal or greater value than such Pledged Securities.

c. Rights With Respect to Distributions. So long as no default shall have occurred and be continuing under this Note, Borrower shall be entitled to receive any and all dividends and distributions made with respect to the Pledged Securities and any other Collateral. However, upon the occurrence and during the continuance of any default, Lender shall have the sole right (unless otherwise agreed by Lender) to receive and retain dividends and distributions and apply them to the outstanding balance of this Note or hold them as Collateral, at Lender’s election.

d. Voting Rights. So long as no default shall have occurred and be continuing under this Note, Borrower shall be entitled to exercise all voting rights pertaining to the Pledged Securities and any other Collateral. However, upon the occurrence and during the continuance of any default, all rights of Borrower to exercise the voting rights that Borrower would otherwise be entitled to exercise with respect to the Collateral shall cease and (unless otherwise agreed by Lender) all such rights shall thereupon become vested in Lender, which shall thereupon have the sole right to exercise such rights.

e. Financing Statement; Further Assurances. Borrower agrees, concurrently with executing this Note, that Lender may file a UCC-1 financing statement relating to the Collateral in favor of Lender, and any similar financing statements in any jurisdiction in which Lender reasonably determines such filing to be necessary. Borrower further agrees that at any time and from time to time Borrower shall promptly execute and deliver all further instruments and documents that Lender may request in order to perfect and protect the security interest

granted hereby, or to enable Lender to exercise and enforce its rights and remedies with respect to any Collateral following an event of default. In addition, following an event of default, Borrower shall deliver the Collateral, including original certificates or other instruments representing the Pledged Securities, to Lender to hold as secured party, and Borrower shall, if requested by Lender, execute a securities account control agreement.

f. Powers of Lender. Borrower hereby appoints Lender as Borrower’s true and lawful attorney-in-fact to perform any and all of the following acts, which power is coupled with an interest, is irrevocable until the Secured Obligations are paid and performed in full, and may be exercised from time to time by Lender in its discretion: To take any action and to execute any instrument which Lender may deem reasonably necessary or desirable to accomplish the purposes of this Section 4(f) and, more broadly, this Note including, without limitation: (i) to exercise voting and consent rights with respect to Collateral in accordance with this Note, (ii) during the continuance of any default hereunder, to receive, endorse and collect all instruments or other forms of payment made payable to Borrower representing any dividend, interest payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same, when and to the extent permitted by this Note, (iii) to perform or cause the performance of any obligation of Borrower hereunder in Borrower’s name or otherwise, (iv) during the continuance of any default hereunder, to liquidate any Collateral pledged to Lender hereunder and to apply proceeds thereof to the payment of the Secured Obligations or to place such proceeds into a cash collateral account or to transfer the Collateral into the name of Lender, all at Lender’s sole discretion, (v) to enter into any extension, reorganization or other agreement relating to or affecting the Collateral, and, in connection therewith, to deposit or surrender control of the Collateral, (vi) to accept other property in exchange for the Collateral, (vii) to make any compromise or settlement Lender deems desirable or proper, and (viii) to execute on Borrower’s behalf and in Borrower’s name any documents required in order to give Lender a continuing first lien upon the Collateral or any part thereof.

5. Additional Terms

a. No Waiver. The acceptance by Lender of payment of a portion of any installment when due or an entire installment but after it is due shall neither cure nor excuse the default caused by the failure of Borrower timely to pay the whole of such installment and shall not constitute a waiver of Lender’s right to require full payment when due of any future or succeeding installments.

b. Default. Any one or more of the following shall constitute a “default” under this Note: (i) a default in the payment when due of any amount hereunder, (ii) Borrower’s refusal to perform any material term, provision or covenant under this Note, (iii) the commencement of any liquidation, receivership, bankruptcy, assignment for the benefit of creditors or other debtor-relief proceeding by or against Borrower, (iv) the transfer by Borrower of any Pledged Securities without being replaced by Pledged Securities in accordance with Section 4(b), and (iv) the levying of any attachment, execution or other process against Borrower, the Collateral or any material portion thereof.

c. Default Rights

i. Upon the occurrence of any payment default Lender may, at its election, declare the entire balance of principal and interest under this Note immediately due and payable. A delay by Lender in exercising any right of acceleration after a default shall not constitute a waiver of the default or the right of acceleration or any other right or remedy for such default. The failure by Lender to exercise any right of acceleration as a result of a default shall not constitute a waiver of the right of acceleration or any other right or remedy with respect to any other default, whenever occurring.

ii. Further, upon the occurrence of any material non-monetary default, following 30 days notice from Lender to Borrower specifying the default and demanded manner of cure for such non-monetary default, Lender shall thereupon and thereafter have any and all of the rights and remedies to which a secured party is entitled after a default under the applicable Uniform Commercial Code, as then in effect. In addition to Lender’s other rights and remedies, Borrower agrees that, upon the occurrence of default, Lender may in its sole discretion do or cause to be done any one or more of the following:

(a) Proceed to realize upon the Collateral or any portion thereof as provided by law, and without liability for any diminution in price which may have occurred, sell the Collateral or any part thereof, in such manner, whether at any public or private sale, and whether in one lot as an entirety, or in separate portions, and for such price and other terms and conditions as is commercially reasonable given the nature of the Collateral.

(b) If notice to Borrower is required, give written notice to Borrower at least ten days before the date of sale of the Collateral or any portion thereof.

(d) Vote all or any part of the Collateral (whether or not transferred into the name of Lender ) and give all consents, waivers and ratifications in respect of the Collateral and otherwise act with respect thereto, as though Lender were the outright owner thereof.

iii. Borrower acknowledges that all or part of foreclosure of the Collateral may be restricted by state or federal securities laws, Lender may be unable to effect a public sale of all or part of the Collateral, that a public sale is or may be impractical and inappropriate and that, in the event of such restrictions, Lender thus may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire the Collateral for their own account, for investment and not with a view to its distribution or resale. Borrower agrees that if reasonably necessary Lender may resort to one or more sales to a single purchaser or a restricted or limited group of purchasers. Lender shall not be obligated to make any sale or other disposition, unless the terms thereof shall be satisfactory to it.

iv. If, in the opinion of Lender based upon written advice of counsel, any consent, approval or authorization of any federal, state or other governmental agency or

authority should be necessary to effectuate any sale or other disposition of any Collateral, Borrower shall execute all such applications and other instruments as may reasonably be required in connection with securing any such consent, approval or authorization, and will otherwise use its commercially reasonable best efforts to secure the same.

v. The rights, privileges, powers and remedies of Lender shall be cumulative, and no single or partial exercise of any of them shall preclude the further or other exercise of any of them. Any waiver, permit, consent or approval of any kind by Lender of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. Any proceeds of any disposition of the Collateral, or any part thereof, may be applied by Lender to the payment of expenses incurred by Lender in connection with the foregoing, and the balance of such proceeds shall be applied by Lender toward the payment of the Secured Obligations.

d. No Oral Waivers or Modifications. No provision of this Note may be waived or modified orally, but only in a writing signed by Lender and Borrower.

e. Attorney Fees. The prevailing party in any action by Lender to collect any amounts due under this Note shall be entitled to recover its reasonable attorneys fees and costs.

f. Governing Law. This Note has been executed and delivered in, and is to be construed, enforced, and governed according to the internal laws of, the State of New York without regard to its principles of conflict of laws that would require or permit the application of the laws of any other jurisdiction.

g. Severability. Whenever possible, each provision of this Note shall be interpreted in such manner as to be effective and valid under applicable law. However, if any provision of this Note shall be held to be prohibited by or invalid under applicable law, it shall be ineffective only to the extent of such prohibition or invalidity without invalidating the remainder of that provision or the other provisions of this Note.

h. Entire Agreement. This Note contains the entire understanding of the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written, with respect to such matters.

Re: Entech Solar, Inc.

Ladies and Gentlemen:

In accordance with the Amended and Restated Preferred Stock Purchase Agreement (“Purchase Agreement”), dated November [ ], 2010, by and between Entech Solar, Inc., a Delaware corporation (“Company”), and Socius CG II, Ltd., a Bermuda exempted company (“Buyer”), pursuant to which Company may issue and deliver shares of common stock of the Company, par value $0.001 per share (“Common Stock”), in payment of the Commitment Fee payable thereunder (the “Commitment Fee Shares”), and a warrant (the “Warrant”) to purchase additional shares of Common Stock (the “Warrant Shares”) (the Commitment Fee Shares and Warrant Shares, collectively, the “Common Shares”), this shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at such time) to issue the Fee Shares and, in the event the holder of the Warrant elects or has elected to exercise all or any portion of the Warrant, from time to time, upon surrender to you of a notice of exercise of the Warrant, the Warrant Shares. Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Purchase Agreement.

Specifically, this shall constitute an irrevocable instruction to you to process any notice of exercise of the Warrant in accordance with the terms of these instructions as soon as practicable. Upon your receipt of a copy of the executed notice of exercise of the Warrant, you shall use your best efforts to, within one (1) Trading Day following the date of receipt of the notice of exercise, (A) issue and surrender to a common carrier for overnight delivery to the address as specified in the notice of exercise a certificate, registered in the name of the Buyer or its designee, for the number of shares of Common Stock to which the Buyer is entitled upon exercise of the Warrant as set forth in the notice of exercise, or (B) provided you are participating in The Depository Trust Company (DTC) Fast Automated Securities Transfer (FAST) Program, upon the request of the Buyer, credit such aggregate number of shares of Common Stock to which the Buyer is entitled to the Buyer’s or its designee’s balance account with DTC through its Deposit Withdrawal At Custodian (DWAC) system provided the Buyer causes its bank or broker to initiate the DWAC transaction.

The Company hereby confirms that the Common Shares should not be subject to any stop-transfer restrictions and shall otherwise be freely transferable on the books and records of the Company. If the Common Shares are certificated, the certificates shall not bear any legend restricting transfer of the shares represented thereby.

The Company hereby confirms and you acknowledge that, in the event counsel to the Company does not issue any opinion of counsel required to issue any Common Shares free of legend, the Company authorizes you to accept an opinion of counsel from Luce Forward Hamilton & Scripps LLP.

The Company hereby confirms that no instructions other than as contemplated herein will be given to you by the Company with respect to the Common Shares. The Company hereby agrees that it shall not replace you as the Company’s transfer agent, until such time as the Company provides written notice to you and Buyer that a suitable replacement has agreed to serve as transfer agent and to be bound by the terms and conditions of this letter agreement regarding Irrevocable Transfer Agent Instructions (this “Agreement”).

The Company and you hereby acknowledge and confirm that complying with the terms of this Agreement does not and shall not prohibit you from satisfying any and all fiduciary responsibilities and duties you may owe to the Company.

The Company and you acknowledge that the Buyer is relying on the representations and covenants made by the Company and you hereunder and that such representations and covenants are a material inducement to the Buyer to enter into the Purchase Agreement. The Company and you further acknowledge that without such representations and covenants made hereunder, the Buyer would not enter into the Purchase Agreement and purchase Securities pursuant thereto.

Each party hereto specifically acknowledges and agrees that a breach or threatened breach of any provision hereof will cause irreparable damage and that damages at law would be an inadequate remedy if this Agreement were not specifically enforced. Therefore, in the event of a breach or threatened breach by a party hereto, including, without limitation, the attempted termination of the agency relationship created by this instrument, in addition to all other rights or remedies, an injunction restraining such breach and granting specific performance of the provisions of this Agreement should issue without any requirement to show any actual damage or to post any bond or other security.

You may at any time resign as transfer agent hereunder by giving thirty (30) days prior written notice of resignation to the Company and the Buyer. Prior to the effective date of the resignation as specified in such notice, the Company will issue to you instructions authorizing delivery of Common Shares to a substitute transfer agent selected by, and in the sole discretion of, the Company. If no successor transfer agent is named by the Company, you may apply to a court of competent jurisdiction in the State of Delaware for appointment of a successor transfer agent and for an order to deposit Common Shares with the clerk of any such court.

The Company must keep its bill current with you – if the Company is not current and is on suspension, the Buyer will have the right to pay the Company’s outstanding bill, in order for you to act upon this Agreement. If the outstanding bill is not paid by the Company or the Buyer, you have no further obligation under this Agreement.

IN WITNESS WHEREOF, the parties have caused this letter agreement regarding Irrevocable Transfer Agent Instructions to be duly executed and delivered as of the date first written above.

Re: Entech Solar, Inc.

Ladies and Gentlemen:

We have acted as counsel to Entech Solar, Inc., a Delaware corporation (the “Company”), in connection with the Amended and Restated Preferred Stock Purchase Agreement dated as of November [ ], 2010 (the “Agreement”), among the Company and Socius CG II, Ltd. (the “Purchaser”), pursuant to which the Purchaser has agreed to purchase from the Company (a) up to an aggregate of $5,000,000 of shares of its Series G Preferred Stock, par value $0.01 per share (the “Series G Preferred Stock”) and (b) a warrant (the “Warrant”) to purchase up to an aggregate of $6,750,000 of shares of its common stock, par value $0.001 per share (the “Common Stock”). Capitalized terms used herein and not otherwise defined shall have the respective meanings given such terms in the Agreement. This opinion is rendered to you pursuant to Section 2.3(e)(ii) of the Agreement.

Although we act generally as counsel to the Company, our representation is limited to matters individually referred to us by the Company’s management.

As to all matters of fact (including factual conclusions and characterizations and descriptions of purpose, intention or other state of mind), we have relied, with your permission, entirely upon (a) the representations and warranties of the parties set forth in the Agreement and each of the other Transaction Documents (as defined below) and (b) certificates of certain of the officers of the Company and have assumed, without independent inquiry, the accuracy of those representations, warranties, and certificates. For purposes of our opinion rendered in paragraph 1 below, with respect to the incorporation, existence and standing of the Company, our opinion relies entirely upon and is limited by the certificate of public official attached hereto as Exhibit A.

In connection with this opinion, we have examined originals or copies of the following documents:

(i)

the Agreement;

(ii)

the Amended and Restated Warrant to Purchase Common Stock dated November [ ], 2010, issued by the Company to Purchaser;

(iii)

the Form of Secured Promissory Note attached as Appendix 2 to the Agreement;

(iv)

the Amended and Restated Certificate of Incorporation of the Company (the “Amended and Restated Certificate”), including the Certificate of Designations of Preferences, Rights and Limitations of Series G Preferred Stock as certified by the Secretary of State of the State of Delaware on [DATE];

(v)

the Amended and Restated By-laws of the Company (the “By-laws”);

(vi)

a Certificate of the President of the Company (the “Company Certificate”);

(vii)

the certificate of certain officers of the Company, as of the date hereof, as to (i) the By-laws of the Company on [DATE], (ii) certain resolutions adopted by written consent of the Board of Directors of the Company (the “Board of Directors”) on February 16, 2010 and November 11, 2010, and (iii) the titles, incumbency, and specimen signatures of certain officers of the Company; and

(viii)

the certificate of public official attached hereto as Exhibit A.

The documents specified in items (i) through (ii) above are referred to herein, collectively, as the “Transaction Documents”. We have examined the documents listed in the preceding paragraph and such other corporate and public records and agreements, instruments, certificates and other documents as we have deemed necessary or appropriate for the purposes of this opinion.

We have assumed the genuineness of all signatures, the conformity to the originals of all documents reviewed by us as copies, the authenticity and completeness of all original documents reviewed by us in original or copy form and the legal competence of each individual executing any document.

For purposes of this opinion, we have made such examination of law as we have deemed necessary. This opinion is limited solely to the internal substantive laws of the State of New York as applied by courts located in New York without regard to choice of law, the federal laws of the United States of America (except for Federal and state tax, antitrust, utilities, national security, anti-money laundering, and blue sky laws, as to which we express no opinion in this letter) and the Delaware General Corporation Law (the “DGCL”) and we express no opinion as to the laws of any other jurisdiction. We have not conducted any special review of statutes, rules or regulations for purposes of this opinion, and our opinions are limited to such laws, rules and regulations as in our experience are normally applicable to transactions of the type contemplated by the Transaction Documents.

We note that certain of the Transaction Documents contain provisions stating that they are governed by the laws of the State of New York, with the exception of matters within the scope of the DGCL, in which case the DGCL shall apply (each contractual choice of law clause being referred to as a “Chosen-Law Provision”). No opinion is given herein as to any Chosen-Law Provision or otherwise as to the choice of law or internal substantive rules of law that any court or other tribunal may apply to the transaction contemplated by the Transaction Documents.

Our opinion is further subject to the following exceptions, qualifications and assumptions, all of which we understand to be acceptable to you:

(a)

We have assumed without any independent investigation that each party to the Agreement and the other Transaction Documents, other than the Company, at all times relevant thereto, is qualified to do business and in good standing under the laws of each jurisdiction where such qualification is necessary in order for such party to enforce its rights under the Transaction Documents.

(b)

We have assumed without any independent investigation that the Company has received the consideration called for by the resolutions of the Board of Directors authorizing the issuance of the Series G Preferred Stock, the Warrant and the Common Stock.

(c)

The enforcement of any obligations of the Company or any other Person, whether under any of the Transaction Documents or otherwise, may be limited by bankruptcy, insolvency, reorganization, moratorium, marshaling or other laws and rules of law affecting the enforcement generally of creditors’ rights and remedies, including, without limitation, fraudulent conveyance and fraudulent transfer laws.

(d)

We express no opinion as to the availability of any specific or equitable relief of any kind.

(e)

The enforcement of any of your rights may in all cases be subject to an implied duty of good faith and fair dealing and to general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity), including without limitation, concepts of materiality and reasonableness.

(f)

We express no opinion as to the enforceability of any particular provision of any Transaction Documents relating to or constituting:

(i) waivers of rights to object to jurisdiction or venue, consents to jurisdiction or venue, or waivers of rights to (or methods of) service of process;

(ii) waivers of rights to trial by jury, or other rights or benefits bestowed by operation of law;

(iii) waivers of any applicable defenses, setoffs, recoupments, or counterclaims;

(iv) the grant of powers of attorney or proxies to the Purchasers;

(v) exculpation or exoneration clauses, clauses relating to indemnification or contribution, and clauses relating to releases or waivers of unmatured claims or rights; and

(vii) the imposition or collection of interest on overdue interest or providing for a penalty rate of interest or late charges on overdue or defaulted obligations, or the payment of any premium, liquidated damages, or other amount which may be held by any court to be a “penalty” or a “forfeiture”.

(g)

We express no opinion as to the effect of events occurring, circumstances arising, or changes of law becoming effective or occurring, after the date hereof on the matters addressed in this opinion letter, and we assume no responsibility to inform you of additional or changed facts, or changes in law, of which we may become aware.

Based upon and subject to the foregoing, and other than as disclosed on the schedules to the Agreement, we are of the opinion that:

1. The Company is a corporation validly existing and in corporate good standing under the laws of the State of Delaware.

2. The Company has the corporate power and authority to execute and deliver each of the Transaction Documents and to issue, sell and deliver the Series G Preferred Stock, the Warrant and the Common Stock and to perform its obligations under each of the Transaction Documents. The Transaction Documents and the execution, delivery and performance thereof have been duly authorized by all necessary corporate action on behalf of the Company.

3. The Series G Preferred Stock, the Warrant and the Common Stock are duly authorized and the Series G Preferred Stock and Common Stock, when issued in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and non-assessable.

4. The execution, delivery and performance by the Company of each of the Transaction Documents and the consummation of the transactions contemplated thereby, including the issuance, sale and delivery of the Series G Preferred Stock, the Warrant and the Common Stock (assuming for the purposes of this paragraph 4 that such Common Stock is issued in accordance with the terms of the Transaction Documents) will not violate any provision of the DGCL or any federal or New York law, statute, rule or regulation applicable to the Company or any existing provision of the Amended and Restated Certificate or the By-laws.

Entech Solar, Inc.

[DATE OF TRANCHE]

5. Each of the Transaction Documents has been duly executed by or on behalf of the Company and constitutes a legal, valid and binding agreement of the Company, enforceable against it in accordance with its terms.

6. The offer and sale to you of the Series G Preferred Stock, the Warrants and the Common Stock pursuant to, and in accordance with, the Transaction Documents do not require registration under the Securities Act of 1933, as amended.

This opinion is rendered to you for your benefit in connection with the transactions contemplated by the Agreement and may not be referred to or used for any other purpose, or delivered to, or relied upon by, any other party without our prior written consent.

Very truly yours,
