ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1            Removal of Legends .

(a)          The Series O Warrants and Series O Warrant Shares may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Series O Warrants or Series O Warrant Shares other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Series O Warrant or Series O Warrant Shares under the Securities Act.

(b)           The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Series O Warrants or Series O Warrant Shares in the following form:

NEITHER THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE HAS 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. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

The Company acknowledges and agrees that a Purchaser 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 Series O Warrants or Series O Warrant Shares to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Series O Warrants or Series O Warrant Shares 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 the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Series O Warrants and Series O Warrant Shares may reasonably request in connection with a pledge or transfer of the Series O Warrants or Series O Warrant Shares.

(c)          Certificates evidencing the Series O Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while a registration statement covering the resale of such Series O Warrant Shares is effective under the Securities Act, or (ii) following any sale of such Series O Warrant Shares in compliance with Rule 144 (assuming cashless exercise of the Series O Warrants), or (iii) if such Series O Warrant Shares are eligible for sale under Rule 144 (assuming cashless exercise of the Series O Warrants) without restriction or limitation, including without the requirement to be in compliance with Rule 144(c)(1), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent or the Purchaser promptly if required by the Transfer Agent to effect the removal of the legend hereunder, or if requested by a Purchaser, respectively. The Company agrees that following such time as such legend is no longer required under this Section 4.1(c), the Company will, no later than the earlier of (i) two Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined below) following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Series O Warrant Shares, as applicable, issued with a restrictive legend (such date, the “ Legend Removal Date ”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Series O Warrant Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of a certificate representing Series O Warrant Shares issued with a restrictive legend. Each Purchaser acknowledges and agrees that the Series O Warrant Shares remain “restricted securities” as such term is defined in Rule 144 notwithstanding removal of the legend set forth above until such Series O Warrant Shares are sold or transferred under an effective registration statement under the 1933 Act or under Rule 144.

(d)          In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated damages and not as a penalty, for each $1,000 of Series O Warrant Shares (based on the VWAP of the Common Stock on the date such Series O Warrant Shares are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading Day (increasing to $20 per Trading Day five Trading Days after such damages have begun to accrue) for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company fails to (a) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing the Series O Warrant Shares so delivered to the Company by such Purchaser that is free from all restrictive and other legends and (b) if after the Legend Removal Date such Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Purchaser of all or any portion of the number of Warrant Shares, that such Purchaser anticipated receiving from the Company without any restrictive legend in compliance with Section 4.1(c), then an amount equal to the excess of such Purchaser’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including brokerage commissions and other out-of-pocket expenses, if any) (the “ Buy-In Price ”) over the product of (A) such number of shares of Common Stock so purchased in lieu of Series O Warrant Shares that the Company was required to deliver to such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price of the Common Stock on any Trading Day during the period commencing on the date of the delivery by such Purchaser to the Company of the applicable Series O Warrant Shares (as the case may be) and ending on the date of such delivery and payment under this Section 4.1(d) and the Company shall deliver to the Purchaser the number of Series O Warrant Shares delivered for removal of the restrictive legend and subject to Section 4.1(c).

(e)          The Shares, the Series P Warrants and the Series P Warrant Shares shall be issued free of legends.

4.2            Furnishing of Information; Public Information .

(b)          At any time during the period commencing from the six month anniversary of the date hereof and ending at such time that all of the Warrant Shares (assuming cashless exercise) may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if the Company (i) shall fail for any reason to satisfy the current public information requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “ Public Information Failure ”) then, in addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Warrant Shares, an amount in cash equal to 2.0% of the aggregate Exercise Price of such Purchaser’s Warrants on the day of a Public Information Failure and on every 30th day (pro rated for periods totaling less than 30 days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public information is no longer required for the Purchasers to transfer the Warrant Shares pursuant to Rule 144. The payments to which a Purchaser shall be entitled pursuant to this Section 4.2(b) are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

4.3            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 Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Series O Warrants or Series O Warrant Shares 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 shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

4.4            Exercise Procedures . The Warrants set forth the totality of the procedures required of the Purchasers in order to exercise the Warrants. Without limiting the preceding sentences, no ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required in order to exercise the Warrants.

Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except: (a) as required by federal securities law in connection with the filing of final Transaction Documents with the Commission; and (b) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).

Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents and the information required to be included in the Disclosure 8-K, which shall be disclosed pursuant to Section 4.5, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented to the receipt of such information and agreed with the Company to keep such information confidential.

(b)          Between the time period of 4:00 pm (New York City time) and 6:00 pm (New York City time) on the Trading Day immediately prior to the Trading Day of the expected announcement of the Subsequent Financing (or, if the Trading Day of the expected announcement of the Subsequent Financing is the first Trading Day following a holiday or a weekend (including a holiday weekend), between the time period of 4:00 pm (New York City time) on the Trading Day immediately prior to such holiday or weekend and 2:00 pm (New York City time) on the day immediately prior to the Trading Day of the expected announcement of the Subsequent Financing), the Company shall deliver to each Purchaser a written notice of the Company’s intention to effect a Subsequent Financing (a “ Subsequent Financing Notice ”), which notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet and transaction documents relating thereto as an attachment .

(c)          Any Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by 6:30 am (New York City time) on the Trading Day following the date on which the Subsequent Financing Notice is delivered to such Purchaser (the “ Notice Termination Time ”) that such Purchaser is willing to participate in the Subsequent Financing, the amount of such Purchaser’s participation, and representing and warranting that such Purchaser has such funds ready, willing, and available for investment on the terms set forth in the Subsequent Financing Notice. If the Company receives no such notice from a Purchaser as of such Notice Termination Time, such Purchaser shall be deemed to have notified the Company that it does not elect to participate in such Subsequent Financing.

(d)          If, by the Notice Termination Time, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their designees to participate) is, in the aggregate, less than the total amount of the Participation Maximum, then the Company may effect the remaining portion of such Participation Maximum on the terms and with the Persons set forth in the Subsequent Financing Notice.

(e)          If, by the Notice Termination Time, the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the aggregate amount of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined below) of the Participation Maximum.  “ Pro Rata Portion ” means the ratio of (x) the Subscription Amount of a Purchaser participating under this Section 4.11 and (y) the sum of the aggregate Subscription Amounts of all Purchasers participating under this Section 4.11.

(f)          The Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of participation set forth above in this Section 4.11, if the definitive agreement related to the initial Subsequent Financing Notice is not entered into for any reason on the terms set forth in such Subsequent Financing Notice by 9:30 am (New York City time) on the second Trading Days following the date of delivery of the initial Subsequent Financing Notice.

(g)          The Company and each Purchaser agree that, in connection with a Subsequent Financing, the transaction documents related to the Subsequent Financing shall include a requirement for the Company to issue a widely disseminated press release by 9:30 am (New York City time) on the Trading Day of execution of the transaction documents in such Subsequent Financing (or, if the date of execution is not a Trading Day, on the immediately following Trading Day) that discloses the material terms of the transactions contemplated by the transaction documents in such Subsequent Financing.

(h)          Notwithstanding anything to the contrary in this Section 4.11 and unless otherwise agreed to by such Purchaser, the Company shall either confirm in writing to such Purchaser that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly disclose its intention to issue the securities in the Subsequent Financing, in either case in such a manner such that such Purchaser will not be in possession of any material, non-public information, by 9:30 am (New York City time) on the third Trading Day following date of delivery of the Subsequent Financing Notice. If by 9:30 am (New York City time) on such third Trading Day, no public disclosure regarding a transaction with respect to the Subsequent Financing has been made, and no notice regarding the abandonment of such transaction has been received by such Purchaser, such transaction shall be deemed to have been abandoned and such Purchaser shall not be deemed to be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries.

(i)          Notwithstanding the foregoing, this Section 4.11 shall not apply in respect of an Exempt Issuance.

4.12          Subsequent Equity Sales .

(b)          From the date hereof until 12 months following the Closing Date, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. “ Variable Rate Transaction ” means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby the Company may issue securities at a future determined price; provided, that, for the avoidance of doubt, the Company’s voluntary reduction of the exercise price of warrants issued and outstanding on the date of this Agreement as permitted pursuant to the terms of such warrants as of the date of this Agreement shall not constitute a Variable Rate Transaction. Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

(c)          Notwithstanding the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall be an Exempt Issuance.

4.13          Equal Treatment of Purchasers . No consideration (including any modification of any Transaction Document) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration is also offered to all of the parties to such Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of the Securities or Warrant Shares or otherwise.

Any proposed waiver, modification, supplement or amendment that disproportionately, materially and adversely affects the rights and obligations of any Purchaser relative to the comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected Purchaser.

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 Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding.

5.11          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 each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, 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 or “.pdf” signature page were an original thereof.

If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

5.13          Rescission and Withdrawal Right . Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided , however , that in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).

5.14          Replacement of Securities and Warrant Shares . If any certificate or instrument evidencing any Securities or Warrant Shares is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), 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. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities or Warrant Shares.

5.15          Remedies . In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers 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 contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.16          Payment Set Aside . To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser 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.

5.17          Independent Nature of Purchasers’ Obligations and Rights . The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and its respective counsel have chosen to communicate with the Company through EGS. EGS does not represent any of the Purchasers and only represents the Placement Agent. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

5.18          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 canceled.

5.19          Saturdays, Sundays, Holidays, etc .         If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

5.20          Construction . The parties agree that each of them and/or their respective counsel have 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 thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.

5.21          WAIVER OF JURY TRIAL . IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

Outstanding options, warrants

In June 2013, the Company issued warrants originally exercisable to purchase 1,683,488 shares (pre-reverse stock splits) of Common Stock (the “June 2013 Warrants), which contain a “formula” anti-dilution provision as well as a provision adjusting the shares and conversion price for stock splits, reverse stock splits and the like. There is currently a total of 17,300 shares of Common Stock issuable upon the exercise of the June 2013 Warrants at an exercise price of $215.00 per share, after adjusting for the applicable reverse stock splits and subsequent issuances of securities but prior to giving effect to the securities issuable under this Agreement.

In addition, there are warrants to purchase 9 shares of Common Stock issued in February 2015 currently outstanding with the right to have their exercise price adjusted to the price of the securities issued under this Agreement.

As disclosed in the Prospectus Supplement, which disclosure is incorporated herein by reference, the Company has agreed in principle to issue and deliver an aggregate of 600,000 unregistered and restricted shares of Common Stock to a group of shareholders (or beneficial owners) who filed a definitive proxy statement with the SEC relating to the solicitation of proxies and seeking, among other things, to withhold all votes for director candidates nominated for election to the Board of Directors at the Company’s 2017 annual meeting of shareholders, as reimbursement for expenses incurred in connection with the 2017 annual meeting of shareholders and the negotiation, execution and effectuation of an agreement to end the withhold proxy solicitation. The Company has not yet executed a binding agreement to do so and is not currently obligated or bound to issue such shares.

As previously disclosed, on April 1, 2016, the Company issued an aggregate of $10,000,000 principal amount of Senior Secured Convertible Notes due April 1, 2019 (the “Convertible Notes”). The Convertible Notes are convertible at any time, at the option of the holders, into shares of Common Stock at the lower of a fixed and floating conversion price. The fixed conversion price is currently $482.10 per share, subject to adjustment for stock splits and similar events. The floating conversion price is equal to the lowest of (i) 85% of the arithmetic average of the five lowest volume-weighted average prices of the Common Stock during the 20 consecutive trading day period ending on the trading day immediately preceding the delivery of the applicable conversion notice by such holder of Convertible Notes, (ii) 85% of the volume-weighted average price of the Common Stock on the trading day immediately preceding the delivery of the applicable conversion notice by such holder of Notes, and (iii) 85% of the volume-weighted average price of the Common Stock on the trading day of the delivery of the applicable conversion notice by such holder of Convertible Notes. The terms of the Convertible Notes permit the Company’s board of directors, with the prior consent of the “required holders” (as defined in the Convertible Notes), to reduce the then current conversion price to any amount and for any period of time deemed appropriate by the Company’s board of directors. In no event may the conversion price be less than $0.25 per share.

In accordance with the terms of the Convertible Notes, the Company has reduced the conversion price under the Convertible Notes for certain time periods at different prices. Most recently, the Company reduced the conversion price to $7.50 for November 22, 2016, November 25, 2016, and November 28 through November 30, 2016.

As of December 22, 2017, the holders of the Convertible Notes have converted an aggregate of $10.5 million of principal and interest under the Convertible Notes, and the Company has issued 659,095 shares of Common Stock at conversion prices between $2.82 and $52.21 per share. As of December 22, 2017, there remains outstanding Convertible Notes with an aggregate principal amount of $1,000.

The Convertible Notes contain certain redemption rights upon, among other things, the occurrence of an event or default or a “fundamental transaction” (as defined in the Convertible Notes).

Stock Appreciation Rights

Under the 2008 Long-Term Incentive Plan (amended and restated November 16, 2016) the Company may grant Stock Appreciation Rights either alone, or in conjunction with other awards, either at the time of grant or by amendment thereafter.

Schedule 3.1(i) Material Changes; Undisclosed Events, Liabilities or Developments

The disclosure about the Regrid Power, Inc. warranty claim and Final Acceptance Payment and Performance Bond, and the potential claim for reimbursement from an insurance carrier related to the July 2014 PIPE Offering (as defined in Schedule 3.1(j) set forth under Schedule 3.1(j) below is incorporated by reference herein.

The disclosure about the Company’s 2017 annual meeting of shareholders and Nasdaq Listing Rule 5620(a) set forth under Schedule 3.1(w) below is incorporated by reference herein.

The disclosure under the heading “PROSPECTUS SUPPLEMENT SUMMARY - Recent Developments” in the Prospectus Supplement is incorporated by reference herein.”

Schedule 3.1(j) Litigation

On July 9, 2014, the Company completed a private offering of approximately $7.0 million of its Common Stock and warrants (the “July 2014 PIPE Offering”). Five of the investors that participated in the offering (out of approximately 20 total investors that participated in the offering) asserted claims against the Company in three separate lawsuits alleging certain misrepresentations and omissions in the offering. The Company subsequently reached settlements with all five investors. The Company recorded a charge to operations of $0.5 million as of June 30, 2015, in recognition of the loss contingency for the July 2014 PIPE offering. That charge was equal to the retention under the Company’s 2014-15 Officers and Directors liability insurance policy as the Company expects the insurance policy will cover any future claims in excess of the retention limit.

The Company received a subpoena from the U.S. Securities and Exchange Commission (“SEC”) requesting certain information pertaining to the Company’s 2014 PIPE Offering. The Company established a special committee of the board of directors to review the facts and circumstances surrounding the PIPE offering and engaged outside counsel to assist it with its review. On May 11, 2016, the Company was advised by the staff of SEC (the “Staff”) that the Staff did not intend to recommend any enforcement action against the Company with respect to the investigation commenced by the Staff in June 2015.

The Company incurred $1.5 million of associated legal expenses related to the subpoena and the July 2014 PIPE Offering. In March 2016, the insurance carrier agreed to pay amounts it believed to constitute defense costs, while reserving all rights, including the right to recoup all amounts paid. The Company has recorded a long-term liability for amounts advanced by the insurance carrier of $1.5 million as of December 31, 2016. The related disclosure under Schedule 3.1(aa) below is incorporated by reference herein.

On November 22, 2016, the Company provided the remaining cash collateral to Argonaut Insurance Company to fully secure the full amount of the $624,000 Final Acceptance Payment and Performance Bond for a large commercial photovoltaic project the Company’s subsidiary Regrid Power, Inc. completed in 2012. As previously disclosed, the customer has raised warranty claims pertaining to the project and the Company currently maintains a specific warranty liability for the project of approximately $200,000. On November 30, 2016, the Company received a letter from the customer in which the customer alleged that the Company has not completed agreed-upon remedial work to remedy alleged deficiencies and notified the Company that the customer intends to perform such remedial work at the Company’s expense using a third-party contractor. The customer also requested that the owner of the project demand the full amount of the performance bond. In addition, the customer demanded an aggregate of approximately $400,000 as liquidated damages under the terms of the project contract. The Company denies these assertions and disputes that the customer is entitled to liquidate damages. The Company plans to avail itself of all defenses and remedies available. The Company estimates that the range of loss related to this warranty claim is from approximately $200,000 to a maximum of approximately $1 million. The Company has recorded a liability for the minimum amount of the range of loss.

On February 16, 2017, Alpha Capital Anstalt (“Alpha”), an investor in the Company’s February 6, 2017 public offering of common stock and warrants, filed a lawsuit against Roth Capital Partners, LLC, the Company’s investment banking firm in the offering, and the Company in U.S. District Court for the Southern District of New York. Alpha’s lawsuit alleges that the registration statement for the February 7, 2017 offering contained material misstatements or omissions and that the Company had breached contractual obligations owed to Alpha. Alpha seeks unspecified monetary damages, rescission and other unspecified relief in the lawsuit. The Company disputes Alpha’s allegations and intends to vigorously defend itself in the lawsuit.  Under local court rules, the Company filed a letter motion seeking permission to file a motion to dismiss the claims related to the alleged misstatements and omissions in the complaint. On May 12, 2017, Alpha filed an amended complaint removing the fraud-related claims and leaving only breach of contract claims against the Company.

Schedule 3.1(w) Listing and Maintenance Requirements

The Company received written notice from Nasdaq on April 14, 2016, indicating that, based on the stockholders’ equity reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, as filed with the SEC on April 1, 2016, the Company was not in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. As set forth in Nasdaq Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Requirement”), listed companies are required to maintain stockholders’ equity of at least $2,500,000.

On December 15, 2016, members of the Company’s management attended a hearing before the NASDAQ Listing Qualifications Panel (the “Panel”). On January 26, 2017, the Company received a determination letter from the Panel, dated January 25, 2017, providing notice that it had regained compliance with Nasdaq’s minimum shareholders’ equity requirement and as such are eligible for continued listing on Nasdaq.

The Company will remain subject to a “Panel Monitor” as that term is defined under Nasdaq Listing Rule 5815(d)(4)(A), through January 15, 2018. Under the terms of the Panel Monitor, in the event the Company’s shareholders’ equity falls below the $2,500,000 threshold (or any other requirement that would ordinarily require the Company to submit a compliance plan to the Nasdaq Staff) during the monitor period and the Company does not qualify for continued listing under an alternative to the shareholders’ equity requirement, the Panel will promptly conduct a hearing with respect to the shareholders’ equity deficiency.

On December 20, 2016, the Company received a letter from Nasdaq notifying it that for the prior 30 consecutive business days, the bid price of the Company’s Common Stock had closed below the minimum $1.00 per-share requirement for continued inclusion on Nasdaq based on Listing Rule 5550(a)(2), and describing a timetable for bringing the Company into compliance with that rule. On February 9, 2017, the Company received a letter from Nasdaq notifying the Company that Nasdaq Staff has determined that for the last 10 consecutive business days, from January 26, 2017 through February 8, 2017, the closing bid price of the Company’s Class A common stock has been at $1.00 per share or greater. Accordingly, the Company has regained compliance with Nasdaq Listing Rule 5550(a)(2).

On August 18, 2017, the Company received a letter from Nasdaq notifying the Company that for the last 30 consecutive business days, the bid price of the Company’s Class A common stock had closed below the minimum $1.00 per share requirement for continued inclusion on Nasdaq based on Listing Rule 5550(a)(2), and describing a timetable for bringing the Company into compliance with that rule.
