WHEREAS, pursuant to the Original Purchase Agreement, the Borrower executed and delivered to Lender that certain Senior Secured, Convertible, Redeemable Debenture dated as of June 30, 2014, but made effective as of October 21, 2014 (such Debenture, together with any other amendments, renewals, substitutions, replacements or modifications from time to time, collectively referred to as the “Debenture”); and

WHEREAS, in connection with the Purchase Agreement and the Debenture, the Borrower and the Guarantors executed and delivered to the Lender various ancillary documents referred to in the Purchase Agreement as the “Transaction Documents”; and

WHEREAS, the Borrower’s obligations under the Purchase Agreement and the Debenture are secured by the following, all of which are included within the Transaction Documents: (i) the Security Agreements; (ii) the Guarantee Agreements; (ii i) the Pledge Agreements; (iv) the Validity Certificates; and (v) UCC-1 Financing Statements naming the Borrower and Corporate Guarantors, as debtors, and Lender, as secured party (collectively, the “UCC-l’s”), among other Transaction Documents; and

WHEREAS, the Borrower, the Guarantors, and Lender desire to enter into certain agreements with respect to the Purchase Agreement and the other Transaction Documents, all as more specifically set fo1ih in this Amendment;

NOW, THEREFORE, in consideration of the premises and the mutual covenants of the parties hereinafter expressed and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, each intending to be legally bound, agree as follows:

1. Recitals. The recitations set forth in the preamble of this Amendment are true and correct and incorporated herein by this reference.

2. Capitalized Terms. All capitalized terms used in this Amendment shall have the same meaning ascribed to them in the Purchase Agreement, except as otherwise specifically set forth herein. In addition, the other definitional and interpretation provisions of Article III of the Purchase Agreement shall be deemed to apply to all terms and provisions of this Amendment, unless the express context otherwise requires.

3. Conflicts. In the event of any conflict or ambiguity by and between the terms and provisions of this Amendment and the terms and provisions of the Purchase Agreement, the terms and provisions of this Amendment shall control, but only to the extent of any such conflict or ambiguity.

4. Modification of Debenture. From and after the date hereof, the Debenture shall be and is hereby severed, split, divided and apportioned into two (2) separate and distinct debentures, as follows:

(a) Replacement Debenture A evidencing a principal indebtedness of Two Hundred Fifty Thousand and No/J 00 Dollars ($250,000.00), and which is being executed and delivered by Borrower to Lender simultaneously herewith (the “Replacement Debenture A”). Replacement Debenture A shall be and remain secured by the Security Agreements, Guarantee Agreements, the Pledge Agreements, the Validity Certificates, the UCC-1’s, and all other applicable Transaction Documents.

(b) Replacement Debenture B evidencing a principal indebtedness of Two Million Two Hundred Ninety-Four Thousand Five Hundred and No/100 Dollars ($2,294,500.00), and which is being executed and delivered by Borrower to Lender simultaneously herewith (the “Replacement Debenture B”, and together with Replacement Debenture A, collectively, the “Replacement Debentures”). Replacement Debenture B shall be and remain secured by the Security Agreements, Guarantee Agreements, the Pledge Agreements, the Validity Certificates, the UCC-1’s, and all other applicable Transaction Documents.

(c) The Replacement Debentures are being executed and delivered simultaneously herewith in substitution for and to supersede the Debenture in its entirety. It is the intention of the Borrower and Lender that while the Replacement Debentures replace and supersede the Debenture, in its entirety, they are not in payment or satisfaction of the Debenture, but rather are the substitute of one evidence of debt for another without any intent to extinguish the old. Nothing contained in this Amendment or in the Replacement Debentures shall be deemed to extinguish the indebtedness and obligations evidenced by the Debenture or constitute a novation of the indebtedness evidenced by the Debenture.

(d) Notwithstanding the splitting of the Debenture into the Replacement Debentures in the principal amounts as contemplated by this Amendment, Borrower understands and acknowledges that all sums received by Lender in payment of the Replacement Debentures, or either one of them, shall be applied by Lender in accordance with the terms of the Purchase Agreement, first to outstanding fees, charges and other costs due and payable under the Purchase Agreement and other Transaction Documents, second to accrued and unpaid interest, and last to outstanding principal. By way of example, and not in limitation, if Replacement Debenture A is sold as contemplated under the Debt Purchase Agreement, upon Lender’s receipt of the purchase price therefor, such amounts received by Lender shall be applied to the total indebtedness evidenced by the Replacement Debentures in the order described above.

(e) Borrower understands and acknowledges that in connection with the Debt Purchase Agreement, it may necessary or desirable, in Lender’s sole and absolute discretion, to have the Borrower further sever, split, divide and app01iion the Replacement Debentures further to accomplish the sale of the Outstanding Claims to Purchaser, as more specifically set forth in the Debt Purchase Agreement. In that regard, within no later than three (3) Business Days after request therefor is made by Lender to Borrower from time to time, the Borrower agrees to further sever, split, divide and apportion the Replacement Debentures, or any of them (or any replacement debentures issued in replacement thereof from time to time), and to execute and deliver such replacement debentures to Lender within such time frames as required or requested by Lender from time to time.

5. Sale of Replacement Debentures.

(a) The parties acknowledge that Lender is entering into this Amendment in connection with the contemplated sale of the indebtedness represented by the Replacement Debentures to Redwood Management, LLC (“Purchaser”) under the terms of a Debt Purchase Agreement (the “Debt Purchase Agreement”) to be entered into promptly after the execution of this Amendment. In the event that the Purchaser fails to purchase all of the Outstanding Claims, the Borrower shall have the right to enter into a similar agreement as the Debt Purchase Agreement, on the same terms, with a new purchaser, which new purchaser shall be deemed a “Purchaser” hereunder. In that regard, the Borrower and Guarantors hereby represent and warrant to Lender as follows, which representations and warranties shall be true and correct as of the date hereof, and which representations and warranties shall be deemed re made and be true and correct as of each sale of the Replacement Debentures (or any replacement debentures issued in replacement thereof from time to time):

(i) All amounts of any nature or kind due and owing by the Borrower and Corporate Guarantors to Lender under the Purchase Agreement and the other Transaction Documents, and represented by the Replacement Debentures or any other Transaction Documents (collectively, the “Outstanding Claims”) are bona fide Outstanding Claims against the Borrower and Corporate Guarantors, respectively and as applicable, and are enforceable obligations of the Borrower and Corporate Guarantors, respectively and as applicable, arising in the ordinary course of business, for services and financial accommodations rendered to the Borrower by Lender in good faith. The Outstanding Claims are currently due and owing and are payable in full.

(ii) The amount of the Replacement Debentures, respectively and as applicable, is the amount due to Lender with respect thereto as of the date hereof, and neither the Borrower, nor the Guarantors, are entitled to any discounts, allowances or other deductions with respect thereto. The aggregate amount of the indebtedness evidenced by the Replacement Debentures was funded by Lender to Borrower at least [X] six months preceding the date hereof, or [  ] one year preceding the date hereof.

(iii) The Outstanding Claims are not subject to dispute by the Borrower or Guarantors, and the Borrower and Corporate Guarantors are unconditionally obligated to pay the full amount of all Outstanding Claims without defense, counterclaim or offset.

(iv) Except for the Purchase Agreement and other Transaction Documents, including this Amendment, there has been no modification, compromise, forbearance, or waiver (written or oral) entered into or given by Lender to Borrower or Guarantors with respect to the Outstanding Claims.

(v) Lender has not filed or commended any action against Borrower or Guarantors based on the Outstanding Claims, and no such action will be pending in any court or other legal venue, and no judgments based upon the Outstanding Claims have been previously entered in favor of Lender in any legal proceeding.

(vi) That the Purchase Agreement and each of the Transaction Documents executed by the Borrower and Guarantors, respectively and as applicable, and all obligations due and owing thereunder, are valid and binding obligations of the Borrower and Guarantors, respectively and as applicable, enforceable against the Borrower and Guarantors in accordance with their respective terms.

(b) The Borrower and Guarantors acknowledge that the Outstanding Claims, or a portion thereof, are being sold by Lender to Purchaser in accordance with the Debt Purchase Agreement, and that payment of the purchase price by Purchaser to Lender for such Outstanding Claims may be conditioned upon the Borrower’s strict compliance with the terms of certain agreements to be entered into between the Borrower and Purchaser (the “Redwood Agreements”). If applicable, Borrower hereby covenants and agrees to strictly comply with each and every term and provision of the Redwood Agreements, including, without limitation, timely issuance and delivery of Common Stock to Purchaser upon conversion by Purchaser of any convertible notes or debentures then in Purchaser’s possession.

(c) The Borrower and Guarantors understand and acknowledge that Lender is relying on the representations, warranties and covenants of the Borrower and Guarantors set forth in this Amendment in order to enter into the Debt Purchase Agreement, and the foregoing representations, warranties and acknowledgements by the Borrower and Guarantors are a material inducement for Lender to agree to a sale of the Outstanding Claims, or portion thereof, to Purchaser, and without this acknowledgement, Lender would not have sold the Outstanding Claims, or portion thereof, to Purchaser.

6. Ratification. The Borrower and Guarantors each hereby acknowledge, represent, warrant and confirm to Lender that: (i) each of the Transaction Documents executed by the Borrower and Guarantors are valid and binding obligations of the Borrower and Guarantors, respectively and as applicable, enforceable against the Borrower and Guarantors in accordance with their respective terms; (ii) all Obligations of the Borrower and Guarantors under the Purchase Agreement, all other Transaction Documents and this Amendment, shall be and continue to be and remain (after execution of this Amendment and the Debt Purchase Agreement) secured by and under the Transaction Documents, including the Security Agreements, Guarantee Agreements, the Pledge Agreements, the Validity Certificates, and the UCC-1 ’s; (iii) there are no defenses, setoffs, counterclaims, cross-actions or equities in favor of the Borrower or Guarantors, to or against the enforcement of any of the Transaction Documents, and to the extent any of the Borrower or Guarantors have any defenses, setoffs, counterclaims, cross-actions or equities against Lender and/or against the enforceability of any of the Transaction Documents, the Borrower and Guarantors each acknowledge and agree that same are hereby fully and unconditionally waived by the Borrower and Guarantors; and (iv) no oral representations, statements, or inducements have been made by Lender, or any agent or representative of Lender, with respect to the Purchase Agreement, this Amendment, or any other Transaction Documents, or the Debt Purchase Agreement.

7. Additional Confirmations. The Borrower and Guarantors hereby represent, warrant and covenant as follows: (i) that the Lender’s Liens and security interests in all of the “Collateral” (as such term is defined in the Purchase Agreement and each of the Security Agreements) are and remain valid, perfected, first-priority security interests in such Collateral, subject only to Permitted Liens, and neither the Borrower, nor the Guarantors, have granted any other Liens or security interests of any nature or kind in favor of any other Person affecting any of such Collateral.

This Amendment, the Replacement Debentures, and each of the documents executed and delivered in connection herewith and therewith have been duly and validly executed by the Borrower and the Corporate Guarantors (and the officer executing this Amendment and all such other documents for each Borrower and Corporate Guarantor is duly authorized to act and execute same on behalf of each Borrower and Corporate Guarantor) and constitute the valid and legally binding agreements of the Borrower and Corporate Guarantors, enforceable against the Borrower and Corporate Guarantors in accordance with their respective terms.

12. Indemnification. Each of the Borrower and Guarantors, jointly and severally, hereby indemnifies and holds the Lender Indemnitees, their successors and assigns, and each of them, harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and distributions of any kind or nature, payable by any of the Lender Indemnitees to any Person, including reasonable attorneys’ and paralegals’ fees and expenses, court costs, settlement amounts, costs of investigation and interest thereon from the time such amounts are due at the highest non-usurious rate of interest permitted by applicable law (collectively, the “Claims”), through all negotiations, mediations, arbitrations, trial and appellate levels, as a result of, or arising out of, or relating to any matters relating to this Amendment, the Purchase Agreement or any other Transaction Documents, including the assertion of a claim or ruling by a Governmental Authority that documentary stamp tax, intangible tax or any penalties or interest associated therewith must be paid by reason of the execution and delivery of any of the Replacement Debentures.

13. Release. As a material inducement for Lender to enter into this Amendment, each of the Borrower and Guarantors does hereby release, waive, discharge, covenant not to sue, acquit, satisfy and forever discharges each of the Lender Indemnitees and their respective successors and assigns, from any and all Claims whatsoever in law or in equity which the Borrower or Guarantors ever had, now have, or which any successor or assign of the Borrower or Guarantors hereafter can, shall or may have against any of the Lender Indemnitees or their successors and assigns, for, upon or by reason of any matter, cause or thing whatsoever related to the Purchase Agreement, this Amendment or any other Transaction Documents, through the date hereof.
