The Purchasers agree to promptly exercise their 2015 Warrants pursuant to Section 2.3 below. To induce the Purchasers to exercise the Series E Warrants, the Company agrees to pay to each Purchaser a warrant exercise fee of $0.04416 for each share purchased by such Purchaser upon exercise of the Series E Warrants from and after the date hereof, such that the net purchase price of such warrants shall be $0.05 per share. The Company agrees to pay the warrant exercise fees to the applicable Purchaser within three (3) business days after the Company receives the proceeds from each exercise of 2015 Warrants. Such warrant exercise fee shall be paid by wire transfer to the account designated by such Purchaser. The payment of the exercise fee pursuant to this agreement shall be the only exercise fee due, notwithstanding any prior agreement between the parties with respect to such fees.

Section 2.2. Antidilution Provisions. The Company and each Purchaser acknowledge and agree that the following antidilution provisions apply:

(a) Section 7(b) of the Series C Certificate of Designation pursuant to Section 8(e) thereof;

(b) Section 3(b) of the Series D Warrants issued February 27, 2015 (the “Series D Warrants”) pursuant to Section 5(l) thereof;

(c) Section 3(b) of the Series F Warrants issued February 27, 2015 (the “Series F Warrants”) pursuant to Section 5(l) thereof; and

(d) Section 3 (b) of the warrant issued February 27, 2015 in favor of Maxim Partners LLC (“Maxim”).

Section 2.3. Exercise of 2015 Warrants. Promptly after the execution of this Agreement by the parties hereto, the Purchasers shall submit a Notice of Exercise and exercise all of their Series E Warrants. The exercise price for the Series E Warrants in connection with such exercise shall be paid in cash by means of wire transfer so long as a Registration Statement covering the exercise of such Series E Warrants is effective and the prospectus therein available at the time of such exercise.

Furthermore, promptly after the execution of this Agreement by the parties hereto, the Purchasers shall submit a Notice of Exercise and exercise sufficient Series D Warrants such that each of the Purchasers (collectively with such Purchaser’s affiliates) shall thereafter be the beneficial owner of 9.98% of the Company’s Common Stock (after taking into account the exercise of Series E Warrants pursuant to this Section 2.3). The computation of such percentage shall be as provided in Section 2 (e) of the Series D Warrant. The exercise price for the Series D Warrants in connection with such exercise shall be paid in cash by means of wire transfer so long as a Registration Statement covering the exercise of such Series D Warrants is effective and the prospectus therein available at the time of such exercise.

Section 2.4. Purchasers’ Agreement to Give Priority to Exercise of the 2015 Warrants. The Purchasers agree that if, after the exercise of 2015 Warrants pursuant to Section 2.3, a Purchaser’s beneficial ownership shall fall below 9.98% of the Company’s Common Stock, and such Purchaser shall desire to acquire additional shares of the Company’s Common Stock, during the term of the 2015 Warrants, such Purchaser shall purchase such Common Stock by exercising sufficient 2015 Warrants such that a minimum of 50% of each such acquisition results from exercise of 2015 Warrants before acquiring such shares pursuant to any other rights to acquire Common Stock (such as the right to convert Series C Stock) until it has acquired all of the shares of the Company’s Common Stock subject to the 2015 Warrants.

The provisions of this Section 2.4 shall be null and void in the event either (x) the Company breaches or is in default of its obligations under any Transaction Document, including, without limitation, the timely payment of all warrant exercise fees pursuant to Section 2.1 in connection with all 2015 Warrant exercises or (y) there is no effective Registration Statement (or the prospectus therein is not available) covering the resale of the Warrant Shares issuable upon exercise of the 2015 Warrants by the Purchasers (assuming such registration is required under the February 27, 2015 Registration Rights Agreement).

Section 2.5. Effect on Existing Documents. The foregoing agreements and consents are given solely in respect of the transactions described herein. Except as expressly set forth herein, all of the terms and conditions of the 2015 Purchase Agreement, Series C Certificate of Designation, Series D Warrants, Series E Warrants, and Series F Warrants shall continue in full force and effect after the execution of this Agreement, and shall not be in any other way changed, modified or superseded by the terms set forth herein.

Section 2.6. Filing of Form 8-K. By 9:00 am (NY time) on the business day immediately following the date hereof, the Company shall issue a Current Report on Form 8-K and a prospectus supplement to the existing Registration Statements, reasonably acceptable to each Purchaser disclosing the material terms of the transactions contemplated hereby, which shall include this Agreement as an attachment thereto.

Section 4.2. Survival. All warranties and representations (as of the date such warranties and representations were made) made herein or in any certificate or other instrument delivered by it or on its behalf under this Agreement shall be considered to have been relied upon by the parties hereto and shall survive the issuance of Common Stock upon exercise of 2015 Warrants.

In the event that any signature is delivered by facsimile transmission, 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 signature page were an original thereof.

Section 4.4. Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Purchaser pursuant hereto, 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 with respect to such obligations or the transactions contemplated by this Agreement.
