“Purchasers”) listed on the Schedule of Purchasers attached as Exhibit A (the “Schedule of Purchasers”). 

WHEREAS, on September 11, 2013, the Company authorized a series of preferred shares designated the “Series J Convertible
Preferred Stock” (“Preferred Shares”), which are convertible into shares of common stock, $0.001 par value per share, of the Company (“Common Stock”) in accordance with the terms of the Amended
and Restated Certificate of Designation governing the Preferred Shares attached hereto as Exhibit B (the “Series J Certificate of Designation”); 

WHEREAS, the Company desires to sell to each Purchaser, and each Purchaser desires to buy from the Company, the number of units of the
Company’s securities (the “Series J Securities”) set forth opposite such Purchaser’s name on the Schedule of Purchasers at a purchase price of $1,000 per Series J Security. Each Series J Security shall consist of
(i) one Preferred Share and (ii) a warrant to purchase 2,650 shares of Common Stock (the “Series J Warrants”) on the terms set forth in the form of warrant attached hereto as Exhibit C. 

WHEREAS, the Company is authorized to sell: (i) 30,000 Series J Units in a series of transactions commencing on the date
hereof and ending on or before December 31, 2014 to the Purchasers and (ii) such number of additional Series J Units as are purchased pursuant to Section 14 of each of the Series H Certificate of Designation, the
Series I Certificate of Designation and the Series J Certificate of Designation as a result of the sale of the Series J Securities to be issued as described in clause (i) above (such issuances described in clause (i) and
(ii) above being collectively referred to as the “Series J Securities Offering”). 
 WHEREAS,
certain capitalized terms as used herein shall have the meaning set forth in Section 5(a) hereof. 
 NOW, THEREFORE, in
consideration of the mutual agreements herein contained, the parties hereto hereby agree as follows: 
 1. Purchase and Sale of Purchased
Securities. 
 (a) Payment for Securities; Delivery of Certificates. Subject to the provisions of this Agreement,
and relying upon the representations, warranties and covenants set forth herein, each Purchaser hereby agrees to purchase from the Company, and the Company hereby agrees to sell to each Purchaser, the number of Series J Securities set forth opposite
such Purchaser’s name on the Schedule of Purchasers (the “Purchased Securities”), free and clear of all Liens (other than restrictions on transfer or Liens under applicable state and federal securities Laws and, with
respect to the Purchased Shares (as defined below), pursuant to the Series J Certificate of Designation), for a purchase price of $1,000 per Series J Security for an aggregate consideration equal to the total consideration set forth opposite such
Purchaser’s name on the Schedule of Purchasers (the “Purchase Price”), which shall be paid in United States dollars. 







 (b) Closing.

Company may sell and issue Series J Securities at a price per Series J Security no less than $1,000 at one or more subsequent closings (each, a “Subsequent Closing”), to such Persons (the “Additional
Purchasers”) as may be approved by the Company. All such sales made at any Subsequent Closing shall be made on the terms and conditions set forth in this Agreement, the representations and warranties of the Company set forth in

of Purchasers may be amended by the Company without the consent of the Purchasers to include any Additional Purchasers upon the execution by such Additional Purchasers of a counterpart signature page hereto. Any Series J Securities sold pursuant to
this Section 1(b)(i) shall be deemed to be “Purchased Securities” for all purposes under this Agreement and any Additional Purchasers thereof shall be deemed to be “Purchasers” for all
purposes under this Agreement. Such Persons shall, upon execution and delivery of a signature page hereto, become parties to, and be bound by, this Agreement without the need for an amendment to this Agreement except to add such Person’s name
to the Schedule of Purchasers, and shall have the rights and obligations hereunder as of the date of the applicable Subsequent Closing. 

(ii) At the Closing: (i) each Purchaser shall transmit, or cause to be transmitted, by wire transfer of immediately
available funds to the Company, in accordance with the wire transfer instructions attached hereto as Annex A an amount equal to such Purchaser’s Purchase Price; (ii) the Company will deliver to each Purchaser certificates
representing such Purchaser’s Preferred Shares (the “Purchased Shares”) and Series J Warrants (the “Purchased Warrants”), registered in the name of each Purchaser in such denominations as such

 2. Company Representations and Warranties. The Company hereby represents and warrants to
each Purchaser as of the date hereof as follows:  
 (a) The Company is a corporation duly incorporated, validly
existing and in good standing under the Laws of the State of Delaware and has the requisite corporate power to carry on its business as presently conducted. The Company is duly qualified to do business as a foreign entity and in good standing in
each state or country, if any, in which failure to be so qualified would, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect. 

(b) The Company has the requisite corporate power and authority to execute, deliver and perform its obligations under the
Transaction Documents and all other instruments, documents and agreements contemplated or required by the provisions of any of the Transaction Documents to be executed, delivered or carried out by the Company hereunder. 

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

(d) Schedule 2(d) attached hereto sets forth, a true, complete and correct listing, as of August 13, 2014, of all of the
Company’s outstanding (i) shares of Common Stock and (ii) securities convertible into or exchangeable for shares of Common Stock (the “Derivative Securities”), including the applicable exercise price of such
Derivative Securities, other than any Derivative Securities issued pursuant to the Company’s Amended and Restated Equity-Based Compensation Plan or the Company’s 2011 Employee Stock Purchase Plan (the “Management
Equity”). Except as set forth in Schedule 2(d) and except for any Management Equity, the Company has no other outstanding equity securities. 

(e) (i) As of its filing date, the Form 10-K filed by the Company with the SEC on March 31, 2014 and the Form 10-Q filed by the Company with the SEC on August 14, 2014 (such filings, collectively, the “Company SEC Documents”) complied in all material respects with the applicable
requirements of the 1933 Act, the 1934 Act, and the Sarbanes-Oxley Act of 2002, as the case may be, including, in each case, the rules and regulations promulgated thereunder. 

(ii) Except to the extent that information contained in the Company SEC Documents has been revised or superseded by a document
the Company subsequently filed with the SEC, the Company SEC Documents do not contain any untrue statement of a material fact or omit 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. 

  
 3 








 (iii) The financial statements (including the related notes thereto) included in
the Company SEC Documents comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP applied on a consistent
basis during the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and their respective
consolidated results of operations and cash flows for the periods then ended, all in accordance with GAAP and the applicable rules and regulations promulgated by the SEC. Since August 14, 2014, the Company has not made any change in the
accounting practices or policies applied in the preparation of its financial statements, except as required by GAAP, the rules of the SEC or policy or applicable Law. 

(iv) Subsequent to the filing of the Company SEC Documents with the SEC, there has been no material and adverse change or
development, or event involving such a prospective change, in the condition, business, properties or results of operations of the Company and its Subsidiaries. 

(f) Securities Law Exemption. Subject to the accuracy of the Purchasers’ representations and warranties in
Section 3, the offer and sale of the Purchased Securities by the Company to each Purchaser pursuant to and in the manner contemplated by this Agreement will be exempt from the registration requirements of the 1933 Act. 

3. Purchaser Representations and Warranties. Each Purchaser, severally and not jointly, represents and warrants with respect to itself
to the Company as follows: 
 (a) Such 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 such 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) Such Purchaser is
knowledgeable in financial matters and is able to evaluate the risks and benefits of an investment in the Purchased Securities. Such 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. Such Purchaser has carefully considered and has, to the extent such Purchaser deems necessary, discussed with such Purchaser’s professional legal, tax, accounting and financial advisers the suitability
of its investment in the Purchased Securities. 
 (d) Such 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. Such Purchaser: (i) understands and acknowledges that the Purchased Securities being issued to such 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 such Purchaser or the fairness of the terms of its investment in the Purchased Securities. 

  
 4 








 (e) Such 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 such Purchaser, enforceable against such Purchaser in
accordance with its terms, and the execution, delivery and performance of this Agreement by such Purchaser does not and will not conflict with, violate or cause a breach of any agreement, Contract or instrument to which such Purchaser is a party or
any judgment, Order or decree to which such Purchaser is subject. 
 (g) Such Purchaser became aware of the offering of the
Purchased Securities other than by means of general advertising or general solicitation. 
 (h) Such 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) Such 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 an applicable 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 a 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. 
 (j) Each Purchaser holding 20% or more of the Company’s voting equity securities (as used in
Rule 506(d)(1) of the 1933 Act) represents that neither (i) such Purchaser, (ii) any of its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or
managing members, nor (iii) any beneficial 

  
 5 








 
owner of the Company’s voting equity securities (in accordance with Rule 506(d) of the 1933 Act) held by such Purchaser is subject to any Disqualification Event, except for Disqualification
Events covered by Rule 506(d)(2) or (d)(3) under the 1933 Act and disclosed reasonably in advance of the Closing in writing in reasonable detail to the Company. 

4. Additional Agreements. 

(a) Purchaser Covenant. Each Purchaser agrees, severally and not jointly as to itself, 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 each 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 each 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. 

(c) 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. 

(d) Certain Actions. Promptly following the date hereof, the Company shall take all actions required to promptly prepare
and file any required notice of exempt offering of securities, including a Form D, with the SEC pursuant to the 1933 Act and/or other comparable form with state securities regulators with respect to any applicable “blue sky” laws, in each
such case, with respect to the transactions contemplated hereby. 
 (e) U.S. Real Property Holding Corporation Status.
So long as any Purchaser beneficially owns any Purchased Shares or any shares of Common Stock issued upon conversion thereof or upon exercise of the Purchased Warrant, the Company shall not become a U.S. real property holding corporation within the
meaning of Section 897 of the Code. 
 (f) Preemptive Rights. Promptly following consummation of the transactions
contemplated by clause (i) of the definition of “Series J Securities Offering,” the Company shall deliver an Issuance Notice (as defined in the Certificates of Designation) to the holders of the Company’s outstanding shares of
Series H Convertible Preferred Stock, the holders of the Company’s outstanding shares of Series I Convertible Preferred Stock and the holders of the Company’s outstanding Preferred Shares and each such holder shall thereafter have the
right, in accordance with Section 14 of the Certificates of Designation (as applicable) to purchase at least a “pro rata share” (as such term is defined in the applicable Certificate of Designation) of the Series J Securities issued
pursuant to such offering (the “Preemptive Rights Offering”). For the avoidance of doubt, the Preemptive Rights Offering shall take into account all Series J Securities issued pursuant to all Closings effected pursuant to
Section 1(b) of this Agreement; provided, however, that each Purchaser (i) hereby expressly and irrevocably waives any rights pursuant to the 

  
 6 








 
Certificates of Designation to purchase any Series J Securities in connection with the Preemptive Rights Offering with respect to the Series J Securities purchased by it hereunder and
(ii) hereby expressly agrees that the amount of Series J Securities such Purchaser may acquire pursuant to any rights to acquire such securities under the Certificates of Designations shall be reduced by the amount of Series J Securities

Purchasers as, and the Company acknowledges that the Purchasers do not so constitute, 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, and the Company shall not assert any such claim with respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Purchasers are not acting in concert or as a group with
respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges and each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the
advice of its own counsel and advisors. A default by any Purchaser of its obligations pursuant to this Agreement shall not constitute a default by any other Purchaser under this Agreement and, except with respect to such defaulting Purchaser, shall
not relieve the Company of any of its

obligations to any other Purchaser under this Agreement. 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 any other Transaction Documents to which it is a party, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.
