Company will not be liable to Purchaser Parties under this Agreement (i) for any settlement by a Purchaser Party effected without Company’s prior written consent, which will 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 Purchaser’s breach of any of the representations, warranties, covenants or agreements made by Purchaser in this Agreement or in the other Transaction Documents.

L.      NASDAQ Listing . On September 19, 2013, Company received notice from The NASDAQ Stock Market that, because the closing bid price for the Common Stock fell below $1.00 per share for 30 consecutive business days, Company did not comply with the minimum bid price requirement for continued listing on the Nasdaq Global Market.

In the event that any signature is delivered by portable document format, facsimile or electronic transmission, such signature will 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 signature page were an original thereof.

P.      Entire Agreement . This Agreement, including the Exhibits hereto, which are hereby incorporated herein by reference, 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.

If, upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the amounts payable with respect to the shares of Series B Preferred Stock are not paid in full, the holders of shares of Series B Preferred Stock will share equally and ratably with the holders of shares of Series A Preferred Stock and Common Stock in any distribution of assets of the Corporation in proportion to the liquidation preference and an amount equal to all accumulated and unpaid Dividends, if any, to which each such holder is entitled.

2.      If, upon any liquidation, dissolution or winding up of the Corporation, the assets of the Corporation will be insufficient to make payment in full to all Holders, then such assets will be distributed among the Holders at the time outstanding, ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

F.      Redemption .

1.      Corporation’s Redemption Option . Upon or after 5 years after the Issuance Date (“ Dividend Maturity Date ”), the Corporation will have the right, at the Corporation’s option, to redeem all or a portion of the shares of Series B Preferred Stock, at a price per share equal to 100% of the Series B Liquidation Value.

2.      Early Redemption . Prior to redemption pursuant to Section I.F.1 hereof, the Corporation will have the right, at the Corporation’s option, to redeem all or a portion of the shares of Series B Preferred Stock at any time or times after the Issuance Date of such Series B Preferred Stock, at a price per share (the “ Early Redemption Price ”) equal to the sum of the following: (a) the Series B Face Value, plus (b) the Embedded Dividend Liability on the date of the applicable redemption or conversion, less (c) any Dividends that have been paid.

3.      Credit Risk Adjustment . Notwithstanding any other provision, the Dividend Rate shall adjust upward by an amount equal to the Credit Spread Adjustment for each amount, if any, equal to the Adjustment Factor, or any portion thereof that the Measuring Metric falls below the Minimum Triggering Level; provided, however, that in no event shall the Dividend Rate be above the Maximum Rate. The Dividend Rate shall adjust downward by an amount equal to the Credit Spread Adjustment for each amount, if any, equal to the Adjustment Factor that the Measuring Metric rises above the Maximum Triggering Level; provided, however, that in no event shall the Dividend Rate be below the Minimum Rate. The Dividend Rate, as adjusted, shall be determined at the time of determination of the Series B Liquidation Amount, Embedded Dividend Liability, Early Redemption Price, or Dividend, as applicable.

4.      Mandatory Redemption. If the Corporation determines to liquidate, dissolve or wind-up its business and affairs, or effect any Deemed Liquidation Event, the Corporation will redeem the Series B Preferred Stock, at the Early Redemption Price set forth in Section I.F.2 if the event is prior to the five-year anniversary of the Issuance Date, or the Series B Liquidation Value if the event is on or after the five-year anniversary of the Issuance Date.

5.      Mechanics of Redemption . If the Corporation elects to redeem any of the Holders’ Series B Preferred Stock then outstanding, it will deliver written notice thereof via facsimile and overnight courier (“ Notice of Redemption at Option of Corporation ”) to each Holder, which Notice of Redemption at Option of Corporation will indicate (a) the number of shares of Series B Preferred Stock that the Corporation is electing to redeem and (b) the applicable Early Redemption Price or Series B Liquidation Value.

6.      Payment of Redemption Price . Upon receipt by any Holder of a Notice of Redemption at Option of Corporation, such Holder will promptly submit to the Corporation such Holder’s Series B Preferred Stock certificates.

G.      Conversion .

1.      Mechanics of Conversion .

a.      Subject to the terms and conditions hereof, one or more of the Series B Preferred Stock may be converted, in part or in whole, into shares of Common Stock, at any time or times after the Issuance Date, at the option of Holder or the Corporation, by (i) if at the option of Holder, delivery of one or more written notices to the Corporation (each, a “ Holder Conversion Notice ”), of the Holder’s election to convert the Series B Preferred Stock and stating the number of shares to which Holder is then entitled, or (ii) if at the option of the Corporation, if the Equity Conditions are met, delivery of written notice to Holder (each, a “ Corporation Conversion Notice ” and, with the Holder Conversion Notice, each a “ Conversion Notice ”), of the Corporation’s election to convert the Series B Preferred Stock. On the same Trading Day on which the Corporation has received the Holder Conversion Notice or issued the Corporation Conversion Notice (as the case may be) by 11:59 a.m. Eastern time, or the following Trading Day if received after such time or on a non-Trading Day, the Corporation shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of the Holder Conversion Notice or issuance of the Corporation Conversion Notice to the Holder and the Corporation’s transfer agent (the “ Transfer Agent ”) and shall either (a) if Corporation is not approved through DTC, issue and surrender to a common carrier for overnight delivery to the address as specified in the Conversion Notice a certificate bearing no restrictive legend, registered in the name of Holder or its designee, for the number of Conversion Shares to which Holder is then entitled as set forth in the Conversion Notice, or (b) provided the Corporation is approved through DTC, authorize the credit by the Transfer Agent of such aggregate number of Conversion Shares to which Holder is then entitled, as set forth in the Conversion Notice, to Holder’s or its designee’s balance account with The Depository Trust Corporation (DTC) Fast Automated Securities Transfer (FAST) Program, through its Deposit/Withdrawal at Custodian (DWAC) system, time being of the essence.

b.      If the Corporation shall fail, for any reason, to issue or cause to be issued to the Holder within 5 Trading Days after receipt of the applicable Conversion Notice, the number of Conversion Shares to which the Holder is entitled as stated in the Conversion Notice, then, in addition to all other remedies available to the Holder, the Corporation shall pay in cash to the Holder on each day after such 5th Trading Day that the issuance of such Conversion Shares is not timely effected an amount equal to 2% of the product of (i) the aggregate number of Conversion Shares not issued to the Holder on a timely basis and to which the Holder is entitled and (ii) the highest Closing Price of the Common Stock between the date on which the Corporation should have issued such shares to the Holder and the actual date of receipt by Holder.

c.      No fractional shares of Common Stock are to be issued upon conversion of Series B Preferred Stock, but rather the Corporation shall issue to Holder scrip or warrants in registered form (certificated or uncertificated) which shall entitle Holder to receive a full share upon the surrender of such scrip or warrants aggregating a full share.

d.      The Holder shall not be required to deliver the original certificates for the Series B Preferred Stock in order to effect a conversion hereunder.

e.      The Corporation shall pay any and all taxes which may be payable with respect to the issuance and delivery of any Conversion Shares.

In the event of a conversion of any Series B Preferred Stock pursuant to an Holder Conversion Notice, the Corporation shall (a) satisfy the Embedded Dividend Liability as provided in Section I.C.2, and (b) issue to the Holder of such Series B Preferred Stock a number of Conversion Shares equal to (i) the Series B Face Value multiplied by (ii) the number of such Series B Preferred Stock subject to the Holder Conversion Notice divided by (iii) the applicable Conversion Price with respect to such Series B Preferred Stock.

3.      Corporation Conversion . The Corporation shall have the right to send the Holder a Corporation Conversion Notice in the event that (x) the Closing Price of the Common Stock exceeds 200% of the Series B-1 Conversion Price for any 20 consecutive Trading Days and (y) the Equity Conditions are met as of the time such Company Conversion Notice is given. Upon any conversion of any Series B Preferred Stock pursuant to a Corporation Conversion Notice, the Corporation shall (a) satisfy the Embedded Dividend Liability as provided in Section I.C.2, , and (b) issue to the Holder of such Series B Preferred Stock a number of Conversion Shares equal to (i) the Series B Face Value multiplied by (ii) the number of such Series B Preferred Stock subject to the Holder Conversion Notice divided by (iii) the applicable Conversion Price with respect to such Series B Preferred Stock.

4.      Stock Splits . If the Corporation at any time on or after the filing of this Certificate of Designations 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 applicable Conversion Price, Adjustment Factor, Maximum Triggering Level, Minimum Triggering Level, and other share based metrics in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock issuable will be proportionately increased. If the Corporation at any time on or after such 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 applicable Conversion Price, Adjustment Factor, Maximum Triggering Level, Minimum Triggering Level, and other share based metrics in effect immediately prior to such combination will be proportionately increased and the number of Conversion Shares will be proportionately decreased. Any adjustment under this Section shall become effective at the close of business on the date the subdivision or combination becomes effective.

5.      Rights . In addition to any adjustments pursuant to Section I.G.4 , if at any time the Corporation 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 Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which Holder could have acquired if Holder had held the number of shares of Common Stock acquirable upon conversion of all Preferred Stock held by Holder 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.

Capitalized terms used herein without definition will have the respective meanings ascribed to them in the Agreement.

Upon your receipt of a copy of a Conversion Notice, you will use your best efforts to, within one Trading Day following the date of receipt of the notice, either (a) if Company is not approved through DTC, issue and surrender to a common carrier for overnight delivery to the address as specified in the notice of exercise a certificate bearing no restrictive legend, registered in the name of the Purchaser or its designee, for the number of Shares to which the Purchaser is entitled upon conversion of as set forth in the notice, or (b) issue pursuant to The Depository Trust Company (DTC) Fast Automated Securities Transfer (FAST) Program, and credit such aggregate number of Shares to which the Purchaser is entitled to the Purchaser’s or its designee’s balance account with DTC through its Deposit Withdrawal At Custodian (DWAC) system, and notify Purchaser to cause its bank or broker to post the DWAC transaction.

We are counsel to Ascent Solar Technologies, Inc., a Delaware corporation (“ Company ”), in connection with the sale and issuance of shares (“ Preferred Shares ”) of Company’s Series B-1 and Series B-2 Preferred Stock (“ Preferred Stock ”), convertible into shares (“ Common Shares ”) of Company’s Common Stock (“ Common Stock ”) to Ironridge Technology Co., a division of Ironridge Global IV, Ltd., a British Virgin Islands business company (“ Purchaser ”), (the Preferred Shares and Common Shares, collectively, “ Shares ”) pursuant to the terms of the Stock Purchase Agreement dated as of October 28, 2013 (“ Agreement ”, and collectively with all documents and agreements related to or arising from the Agreement, the “ Transaction Documents ”), by and between Company and Purchaser. Capitalized terms not otherwise defined herein have the meanings set forth in the Transaction Documents.

We are of the opinion that, as of the date hereof:

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

2.      The Shares are duly authorized and, when issued in accordance with the terms and conditions of the Agreement will be, legally and validly issued, fully paid and non-assessable. The issuance of the Shares will not be subject to any statutory or, to our knowledge, contractual preemptive rights of any stockholder of Company.

3.      Company has the corporate power and authority to (a) execute, deliver and perform all of its obligations under the Agreement and the Transaction Documents, and (b) issue, sell and deliver the Shares.

4.      The execution, delivery and performance of the Agreement and the Transaction Documents have been duly authorized by all necessary corporate action on the part of Company, and have been duly executed and delivered by Company.

5.      Upon execution and delivery of the Agreement, the Agreement will constitute the legal, valid and binding obligation of Company, enforceable against Company in accordance with its terms.

6.      The execution and delivery of the Transaction Documents by Company does not, and Company’s performance of its obligations thereunder will not (a) violate the Second Amended and Restated Certificate of Incorporation or the Amended and Restated By-Laws of Company, as in effect on the date hereof, (b) violate in any material respect any federal or state law, rule or regulation, or judgment, order or decree of any state or federal court or governmental or administrative authority, in each case that, to our knowledge, is applicable to Company or its properties or assets and which could have a material adverse effect on Company’s business, properties, assets, financial condition or results of operations or prevent the performance by Company of any material obligation under the Agreement, or (c) to our knowledge, require the authorization, consent, approval of or other action of, notice to or filing or qualification with, any state or federal governmental authority, except (i) as have been, or will be prior to the Closing, duly obtained or made, or (ii) to the extent failure to be so obtained or made would not have a material adverse effect on Company or its ability to consummate the transactions contemplated under the Agreement.

7.      To our knowledge, there is no claim, action, suit, proceeding, arbitration, investigation or inquiry, pending or threatened, before any court or governmental or administrative body or agency, or any private arbitration tribunal, against Company that challenges the validity or enforceability of, or seeks to enjoin the performance of, the Agreement.

8.      Company is not, and immediately after the consummation of the transactions contemplated by the Agreement will not be, an investment company within the meaning of Investment Company Act of 1940, as amended.

9.      The Registration Statement filed with the Commission, which registers the sale of the Shares to Purchaser is current and effective as of the date hereof.

In addition to the opinions above, nothing has come to our attention that has caused us to believe that the Registration Statement, as of its effective date, or the Prospectus Supplement, as of its date or the date of its letter (in each case, except as to the financial statements, schedules, notes, other financial and accounting data, and statistical data, included therein or derived therefrom, as to which we express no opinion or belief), contained any untrue statement of material fact, or failed to state a material fact necessary in order to make the facts stated therein, in light of the circumstances in which they were made, not misleading.
