(b)       Each Subscriber agrees to the imprinting, so long as is required by this Section 5.1, of a legend on the Notes, in the following form:

[NEITHER] THIS SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE] HAS [NOT] 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 AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY [AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE NOTES.

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

5.3       Indemnification. 

(a)       The Company agrees to indemnify and hold harmless each Subscriber, its affiliates and their respective officers, directors, employees, agents and controlling persons (collectively, the “Indemnified Parties”) from and against any and all loss, liability, damage or deficiency suffered or incurred by any Indemnified Party by reason of any misrepresentation or breach of warranty by the Company or, after any applicable notice and/or cure periods, nonfulfillment of any covenant or agreement to be performed or complied with by the Company under this Agreement and the other Transaction Documents. The Company will promptly reimburse the Indemnified Parties for all expenses (including reasonable fees and expenses of legal counsel) as incurred in connection with the investigation of, preparation for or defense of any pending or threatened claim related to or arising in any manner out of any of the foregoing, or any action or proceeding arising therefrom (collectively, “Proceedings”), whether or not such Indemnified Party is a formal party to any such Proceeding.

(b)       If for any reason (other than a final non-appealable judgment finding any Indemnified Party liable for losses, claims, damages, liabilities or expenses for its fraud, gross negligence or willful misconduct) the foregoing indemnity is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless, then the Company shall contribute to the amount paid or payable by an Indemnified Party as a result of such loss, claim, damage, liability or expense in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Indemnified Party on the other, but also the relative fault by the Company and the Indemnified Party, as well as any relevant equitable considerations.

5.4       Use of Proceeds. The Company shall use the net proceeds from the sale of the Notes for working capital and general corporate purposes.

No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

6.3       This Agreement shall be binding upon and inure to the benefit of the parties hereto and to their respective heirs, legal representatives, successors and assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Subscribers (other than by merger).

6.4       The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

6.5       Upon the execution and delivery of this Agreement by each Subscriber and the Company, this Agreement shall become a binding obligation of such Subscriber with respect to the purchase of the Notes as herein provided, subject, however, to the right hereby reserved by the Company to enter into the same agreements with other Subscribers and to reject any subscription, in whole or in part, provided the Company returns to a Subscriber any funds paid by such Subscriber with respect to such rejected subscription or portion thereof, without interest or deduction.

6.6       All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof.

6.7       In order to discourage frivolous claims the parties agree that unless a claimant in any proceeding arising out of this Agreement succeeds in establishing his claim and recovering a judgment against another party (regardless of whether such claimant succeeds against one of the other parties to the action), then the other party shall be entitled to recover from such claimant all of its/their reasonable legal costs and expenses relating to such proceeding and/or incurred in preparation therefor.

6.9       It is agreed that a waiver by either party of a breach of any provision of this Agreement shall not operate, or be construed, as a waiver of any subsequent breach by that same party.

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.

6.12       Nothing in this Agreement shall create or be deemed to create any rights in any person or entity not a party to this Agreement.

6.13       In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each Subscriber and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

6.14       Each Subscriber acknowledges and agrees that subject to the cure periods described Section 4(a) of the Notes, upon any Event of Default (as defined in the Notes) the Series F 15% Senior Secured Notes, due June 30, 2018, in the principal amount of $2,000,000 (the “Candlewood Series F Notes”), issued to Candlewood Structured Credit Harvest Master Fund LP (“Candlewood Harvest”) and Candlewood Structured Credit Opportunity Master Fund A LP (“Candlewood Opportunity” and together with Candlewood Harvest, “Candlewood”), by the Company shall immediately be due and payable, including, without limitation, the entire outstanding principal amount of the Candlewood Series F Notes, all accrued and unpaid interest thereon, and any other amounts due under the Candlewood Series F Notes. Further, upon any Event of Default (as defined in the Notes), the Candlewood Series F Notes shall be deemed pari passu with the Series G 15% Original Issue Discount Senior Secured Promissory Notes issued to Candlewood, in all respects, including, without limitation, the security interests granted to Candlewood under the Candlewood Series F Notes. For the avoidance of doubt, upon any Event of Default (as defined in the Notes), subject to the cure periods described in Section 4(a)) of the Notes, Candlewood’s claims against the Company shall be deemed senior to any and all claims by any other Subscriber.
