3. Purchaser Representations and Warranties. Purchaser hereby represents and warrants to the Company as follows:

(a) Purchaser has the full power and authority to execute and deliver this Agreement and to perform all of its obligations hereunder and thereunder, and to purchase, acquire and accept delivery of the Purchased Securities.

(b) The Purchased Securities are being acquired for Purchaser’s own account and not with a view to, or intention of, distribution thereof in violation of the 1933 Act, or any applicable state securities Laws.

(c) Purchaser is knowledgeable in financial matters and is able to evaluate the risks and benefits of an investment in the Purchased Securities. Purchaser understands and acknowledges that such investment is a speculative venture, involves a high degree of risk and is subject to complete risk of loss. Purchaser has carefully considered and has, to the extent Purchaser deems necessary, discussed with Purchaser’s professional legal, tax, accounting and financial advisers the suitability of its investment in the Purchased Securities.

(d) Purchaser is able to bear the economic risk of its investment in the Purchased Securities for an indefinite period of time because the Purchased Securities have not been registered under the 1933 Act and, therefore, cannot be sold unless subsequently registered under the 1933 Act or an exemption from such registration is available. Purchaser: (i) understands and acknowledges that the Purchased Securities being issued to Purchaser have not been registered under the 1933 Act, nor under the securities Laws of any state, nor under the Laws of any other country and (ii) recognizes that no public agency has passed upon the accuracy or adequacy of any information provided to Purchaser or the fairness of the terms of its investment in the Purchased Securities.

(e) Purchaser has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of the Purchased Securities and has had full access to such other information concerning the Company as has been requested.

(f) This Agreement constitutes the legal, valid and binding obligation of Purchaser, enforceable against Purchaser in accordance with its terms, and the execution, delivery and performance of this Agreement by Purchaser does not and will not conflict with, violate or cause a breach of any agreement, Contract or instrument to which Purchaser is a party or any judgment, Order or decree to which Purchaser is subject.

(g) Purchaser became aware of the offering of the Purchased Securities other than by means of general advertising or general solicitation.

(h) Purchaser is an “accredited investor” as that term is defined under the 1933 Act and Regulation D promulgated thereunder, as amended by Section 413 of the Private Fund Investment Advisers Registration Act of 2010 and any applicable rules or regulations or interpretations thereof promulgated by the SEC or its staff.

(i) Purchaser acknowledges that the certificates for the Purchased Shares will contain a legend substantially as follows:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE. THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS.”

Subject to any lock-up or other similar agreement that may apply to the Purchased Shares as may be specifically agreed to with Purchaser, the requirement that the Purchased Shares contain the legend set forth in clause (i) above shall cease and terminate when such shares are transferred pursuant to Rule 144 promulgated under the 1933 Act. Upon the consummation of an event described in the immediately preceding sentence, the Company, upon surrender of

certificates containing such legend, shall, at its own expense (without the need for any opinion of counsel for Purchaser), deliver to the holder of any such securities as to which the requirement for such legend shall have terminated, one or more new certificates evidencing such securities not bearing such legend.

4. Additional Agreements.

(a) Purchaser Covenant. Purchaser agrees not to make any sale, transfer or other disposition of the Purchased Securities in violation of the 1933 Act, the 1934 Act, the rules and regulations promulgated thereunder or any applicable securities Laws.

(b) Tax Provision. The Company and Purchaser intend that for U.S. federal, state and local income tax purposes, the Purchased Securities will be treated as equity and each of the Company and Purchaser agrees that it will not take any position to the contrary with respect to any Purchased Securities it acquires pursuant to the terms of this Agreement.

For so long as a Purchaser continues to beneficially own, in the aggregate, at least 5,000 Preferred Shares, shares of Series H Preferred Stock and/or shares of Series I Preferred Stock (or the equivalent amount of Conversion Shares), during normal business hours, the Company shall provide to Purchaser reasonable access to customary information, access and inspection rights, including delivering to Purchaser the following information (collectively, the “Public Company Information”):

vii. in lieu of providing the information required under the foregoing Section 4(c)vi, as soon as practicable after the end of the first, second and third quarterly accounting periods in each fiscal year of the Company, and in any event within forty-five (45) days thereafter (to the extent practicable), an unaudited consolidated balance sheet of the Company and the Company Subsidiaries as of the end of each such quarterly period, and unaudited consolidated statements of income and cash flows of the Company and the Company Subsidiaries for such period and for the current fiscal year to date, prepared in accordance with GAAP and setting forth in comparative form the figures for the corresponding periods of the previous fiscal year, subject to changes resulting from normal year-end audit adjustments, all in reasonable detail, except that such financial statements need not contain the notes required by GAAP.

The foregoing confidentiality restriction shall not apply to any Company Information that is in the public domain, becomes part of the public domain after disclosure to Purchaser other than due to a breach by Purchaser of this Section 4, was within Purchaser’s possession or developed by it prior to being furnished with such information as evidenced by Purchaser’s records, or becomes available to Purchaser on a non-confidential basis from a source other than the Company.

(e) Terms of the Preferred Shares. Each of the parties hereto acknowledges that the Preferred Shares shall have the powers, preferences and rights, and be subject to the qualifications, limitations or restrictions set forth in the Series J Certificate of Designation.

Purchaser hereby expressly and irrevocably waives, on its own behalf and on behalf of its Affiliates, any rights pursuant to the Certificates of Designation to purchase any securities of the Company in connection with the Preemptive Rights Offering.

(j) Amendments to Certificates of Designation. Contemporaneously with the execution of this Agreement, Purchaser shall deliver a written consent to the Company pursuant to which Purchaser consents and agrees to the Series I/J Certificate of Designation Amendments.

(k) Consent to Subsequent Offerings. To the extent the consent of Purchaser to any subsequent offers or sales of Preferred Shares and warrants to purchase shares of Common Stock would be required pursuant to the terms of any of the Certificates of Designation, Purchaser hereby agrees to consent to such offering(s) to the extent (and only to the extent) that such offering(s) meet all of the following criteria (each, a “Subsequent Offering”):

i. it is consummated on or before April 30, 2014;

ii. it is offered to the holders of the then-outstanding shares of Series H Preferred Stock, Series I Preferred Stock and Preferred Shares pursuant to Section 14(a) or Section 14(c) of the Certificates of Designation, as applicable;

iii. it is not an “Exempt Equity Issuance” as defined in the Certificates of Designation;

iv. it consists of Preferred Shares and warrant(s) to purchase shares of Common Stock that have terms equivalent in all material respects to the Preferred Shares and the Form of Warrant issued pursuant to this Agreement (including, without limitation, at the ratio established for each Purchased Security);

v. the purchase price results in gross proceeds to the Company in an amount less than, or equal to, $30,000,000 in the aggregate together with any and all other such Subsequent Offerings; and

vi. notwithstanding anything herein to the contrary, including without limitation Section 4(l), Purchaser expressly reserves all of its and its Affiliates’ rights pursuant to the Certificates of Designation with respect to any Subsequent Offering, including without limitation any rights offerings related thereto; provided, however, that for the avoidance of doubt, the term Subsequent Offering as used herein shall not include the Rights Offering of an aggregate of 6,000 Preferred Shares and warrants to purchase an aggregate of 15,900,000 shares of Common Stock, as set forth in Section 4(l).

(l) Rights Offering. The Company shall use its commercially reasonable efforts to conduct a rights offering providing the holders of record of Common Stock as of the close of business on a designated record date the right to purchase Preferred Shares and warrants to purchase shares of Common Stock on the terms set forth in the Form of Warrant at a price equivalent in all material respects to the price paid by the Purchaser pursuant to this Agreement (including, without limitation, at the ratio established for each Purchased Security) (the “Rights Offering”). The Company shall use its commercially reasonable efforts to file the registration statement in connection with the Rights Offering as soon as reasonably practicable after the filing of the Company’s annual report on Form 10-K for the 2013 fiscal year. The Rights Offering shall offer the right to purchase units of the Company’s securities, which units shall consist of an aggregate of 6,000 Preferred

Shares and warrants to purchase an aggregate of 15,900,000 shares of Common Stock. The foregoing notwithstanding, to the extent that facts and circumstances related to the Company have changed prior to the commencement of the Rights Offering such that the Rights Offering would no longer be commercially reasonable, the Board of Directors of the Company may affirmatively determine not to proceed with the Rights Offering. To the extent the consent of Purchaser to the Rights Offering would be required pursuant to the terms of any of the Certificates of Designation, Purchaser hereby agrees to consent to the Rights Offering. Purchaser and its Affiliates shall not have, and hereby expressly and irrevocably waives on its own behalf and on behalf of its Affiliates, any right to participate in the Rights Offering and further agrees to not exercise any rights that Purchaser or its Affiliates may receive pursuant to the Rights Offering.

(m) Amended and Restated Certificate of Incorporation. Not later than July 31, 2014, the Company shall use its best efforts to cause its Certificate of Incorporation to be amended to increase the number of authorized shares of Common Stock of the Company to such number as shall be sufficient to permit the reservation in full of shares of Common Stock underlying all outstanding Derivative Securities (the “Charter Amendment”). Purchaser shall vote, and cause its Affiliates to vote, all shares of Capital Stock that are owned (or to the extent that any such shares are owned in “street name,” beneficially owned) by Purchaser or its Affiliates at any annual or special meeting of the Company’s stockholders or will vote for or render consent in writing in favor of the Charter Amendment.

(n) Qualified Follow-On. The Company hereby agrees that the issuance and sale of the Purchased Securities pursuant to this Agreement and the other subscription agreements being entered into on the date hereof shall be deemed to constitute a Qualified Follow-On (as defined in the Existing Subscription Agreements) and that the Existing Holders shall have the right to elect to exchange all or any part of their Preferred Shares for Preferred Shares and warrants to purchase shares of Common Stock on the terms set forth in the Form of Warrant (at the ratio established for each Purchased Security).

(o) Purchaser Expenses. The Company shall pay the reasonable and documented out-of-pocket fees and expenses of Purchaser, including the fees and expenses of attorneys, accountants and consultants employed by Purchaser to the extent that such fees and expenses relate to services rendered in conjunction with the Purchaser’s investment in the Purchased Securities.

5. Indemnification by the Company.

(a) Subject to the limitations and other provisions of this Section 5, the Company shall save, defend, indemnify and hold harmless Purchaser and its affiliates and the respective representatives, directors, officers, employees, members, managers, partners, stockholders, controlling Persons, agents, representatives, successors and assigns of each of the foregoing from and against any and all losses, damages, liabilities, deficiencies, claims, interest, awards, judgments, penalties, costs and expenses (including reasonable out-of-pocket attorneys’ fees, costs and other out-of-pocket expenses incurred in investigating, preparing or defending the foregoing), asserted against, incurred,

sustained or suffered by any of the foregoing as a result of, arising out of or relating to any breach of any representation, warranty or covenant made by the Company and contained in this Agreement and the Disclosure Schedule.

(b) Purchaser shall give notice to the Company promptly after Purchaser has actual knowledge of any claim as to which indemnity may be sought, and to the extent such claim is a third party claim, shall permit the Company to assume the defense of any such third party claim or any litigation resulting therefrom; provided, that counsel for the Company who shall conduct the defense of such third party claim or any litigation resulting therefrom shall be approved by Purchaser (such approval shall not unreasonably be withheld conditioned or delayed), and Purchaser may participate in such defense at its expense (other than as provided below), and provided further, that the failure of Purchaser to give notice as provided herein shall not relieve the Company of its obligations under this Agreement, except to the extent that the Company is actually and materially prejudiced thereby. Purchaser, at the Company’s cost and expense, shall furnish such information regarding itself or the claim in question as the Company may reasonably request and as shall be reasonably required in connection with the defense of any such third party claim and/or litigation resulting therefrom. Purchaser shall have the right to retain its own counsel, with the fees and expenses to be paid by the Company, if (i) the Company fails to prosecute the applicable third party claim or litigation resulting therefrom in a prompt and timely fashion and/or (ii) representation of Purchaser by the counsel retained by the Company would be inappropriate due to actual or potential differing interests between Purchaser and any other party represented by such counsel in such proceeding; provided, that in no event shall the Company be required to pay the fees and expenses of more than one such separate counsel (other than foreign counsel) for Purchaser. Notwithstanding anything in this Section 5(b) to the contrary, neither the Company nor Purchaser shall, without the prior written consent of the other party, settle or compromise any third party claim as to which indemnity may be sought or permit a default or consent to entry of any judgment unless the claimant (or claimants) and such party provide to such other party an unqualified release from all liability in respect of such third party claim; provided, that the prior written consent of Purchaser shall be required for the Company to take any of such actions if the taking of such actions could or could reasonably be expected to reduce or limit the rights or indemnification recoveries available to, or otherwise increase the liability of or losses to, either Purchaser, its affiliates and their respective representatives, directors, officers, employees, members, managers, partners, stockholders, controlling Persons, agents, representatives, successors and assigns. If the Company makes any payment on any claim, the Company shall be subrogated, to the extent of such payment, to all rights and remedies of Purchaser to any insurance benefits or other claims of Purchaser with respect to such claim.

(c) Survival. The representations and warranties set forth in Sections 2(a) (Organization), 2(b) (Power), 2(c)i (Authorization), 2(d) (Capital) and 2(f) (Capitalization) shall survive the Closing for the maximum period permitted by applicable Law, and all other representations and warranties of the parties set forth in this Agreement and the other Transaction Documents shall terminate upon the Closing and thereafter shall be of no further force or effect. Following the expiration of the periods set forth above with respect to any particular representation or warranty, no party hereto

shall have any further liability with respect to such representation or warranty. Except as set forth herein, all of the covenants, agreements and obligations of the parties hereto shall survive the Closing indefinitely (or if indefinite survival is not permitted by Law, then for the maximum period permitted by applicable Law). A claim for indemnification related to a breach of any of the representations and warranties becomes barred if not filed or noticed during the survival period; and the parties hereto intend to shorten (in the case of limited survival provisions) the applicable statute of limitations. Notwithstanding anything herein to contrary, any claim for indemnification that is asserted by written notice within the survival period shall survive until resolved pursuant to a final non-appealable judicial determination or a written agreement between the Company and Purchaser.
