-2-

3. Registration of Transfers. The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto as Appendix A duly completed and signed, to the Company at its address specified herein. Upon any such registration and transfer, a new warrant in substantially the form of a Warrant (any such new warrant, a “New Warrant”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

4. Exercise and Duration of Warrant.

(a) This Warrant shall be exercisable by the registered Holder at any time and from time to time on and after the Initial Exercise Date to and including the Expiration Date. At 5:00 P.M. New York City time on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value.

(b) A Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached hereto as Appendix B (the “Exercise Notice”), appropriately completed and duly signed, and (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised, and the date such items are received by the Company is an “Exercise Date.” Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

(c) The Holder shall pay the Exercise Price (i) in cash, by certified bank check payable to the order of the Company or by wire transfer of immediately available funds in accordance with the Company’s instructions or (ii) if on or after the six (6) month anniversary of the Original Issue Date (x) there is no effective Registration Statement registering the resale of the Warrant Shares by the Holder and (y) the Market Price exceeds the Exercise Price, by means of a “cashless exercise,” by presenting and surrendering to the Company this Warrant, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y [(A-B)/A] where:

X = the number of Warrant Shares to be issued to the Holder upon such cashless exercise;

Y = the number of Warrant Shares with respect to which this Warrant is being exercised;

A = the Market Price on the Exercise Date; and

B = the Exercise Price.

(d) Notwithstanding anything to the contrary herein, Holder agrees that the no exercises of this Warrant or conversions of the Note sold in the Offering shall be permitted unless the Company has sufficient number of authorized common stock available to accommodate such exercises or conversions.

(e) Notwithstanding anything herein to the contrary, the Company shall not issue to the Holder, and the Holder may not acquire, a number of shares of Common Stock upon exercise of this Warrant to the extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by the Holder and its affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) would exceed 9.99% of the total number of shares of Common Stock then issued and outstanding (the “Beneficial Ownership Limitation”). For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Securities and Exchange Commission, and the percentage held by the Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. For purposes of this Section, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be or (B) a more recent public announcement by the Company. Upon the written or oral request of a Holder, the Company shall within two trading days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

-3-

5. Delivery of Warrant Shares.

(a) Upon exercise of this Warrant, the Company shall within three Trading Days after receipt of the Exercise Notice attached hereto as Appendix B, issue or cause to be issued and deliver or cause to be delivered to the Holder, in such name or names as the Holder may designate, a certificate for the Warrant Shares issuable upon such exercise bearing (only if such legend is required by applicable law) the restrictive legend set forth in Section 4(j)(ii) of the Subscription Agreement. The Holder, or any Person so designated by the Holder to receive the Warrant Shares, shall be deemed to have become holder of record of such Warrant Shares as of the Exercise Date.

(b) This Warrant is exercisable, either in its entirety or, from time to time, for a portion of the number of Warrant Shares. Upon surrender of this Warrant following one or more partial exercises, the Company shall issue or cause to be issued, at its expense, a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

6. Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrant in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and in substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested.

8. Reservation of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares that are then issuable and deliverable upon the exercise of this entire Warrant, free from all taxes, liens, claims, encumbrances with respect to the issuance of such Warrant Shares and will not be subject to any pre-emptive rights or similar rights (taking into account the adjustments and restrictions of Section 9 hereof). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued, fully paid and nonassessable. The Company will take all such action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Stock may be listed or quoted, as the case may be.

-4-

9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9.

(a) Stock Dividends. If the Company, at any time while this Warrant is outstanding, pays a dividend on its Common Stock payable in additional shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, then in each such case the Exercise Price shall be multiplied by a fraction, (i) the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to the opening of business on the day after the record date for the determination of stockholders entitle to receive such dividend or distribution and (ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section 9(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution.

(b) Stock Splits. If the Company, at any time while this Warrant is outstanding, (i) subdivides outstanding shares of Common Stock into a larger number of shares, or (ii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction, (A) the numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment pursuant to this Section 9(b) shall become effective immediately after the effective date of such subdivision or combination.

(c) Reclassifications. A reclassification of the Common Stock (other than any such reclassification in connection with a merger or consolidation to which Section 9(f) applies) into shares of any other class of stock shall be deemed:

(i) a distribution by the Company to the holders of its Common Stock of such shares of such other class of stock for the purposes and within the meaning of this Section 9; and

(ii) if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as part of such reclassification, such change shall be deemed a subdivision or combination, as the case may be, of the outstanding shares of Common Stock for the purposes and within the meaning of Section 9(b) hereof.

(d) Subsequent Financing. If, at any time within six (6) months from the date hereof, the Company sells or grants any option to purchase, or grants any right to reprice, or otherwise dispose of or issues, any Common Stock or Common Stock Equivalents entitling any person to acquire shares of Common Stock at an effective price per share that is lower than the Exercise Price, other than in connection with any Common Stock Equivalents outstanding on the Closing (such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance), then the Exercise Price shall be reduced to equal one hundred twenty five (125%) of such Base Share Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 9(d) in respect of an Exempt Issuance. “Exempt Issuance” means the issuance of (a) shares of Common Stock or options to employees, consultants, officers or directors of the Company pursuant to any stock or option plan or agreement duly adopted by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose, (b) securities upon the exercise or exchange of or conversion of any securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding on the date hereof, (c) securities issued or to be issued by the Company pursuant to that certain Purchase Agreement dated as of February 18, 2013, as amended to date, by and between the Company and Lincoln Park Capital Fund, LLC, as amended to date, (d) securities issued pursuant to acquisitions or strategic transactions with a third party non-affiliate of the Company approved by a majority of the then disinterested directors of the Company, provided that any such issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company or an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities.

-5-

(e) Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition for value of any such shares shall be considered an issue or sale of Common Stock.

(f) Adjustments. Notwithstanding any provision of this Section 9, no adjustment of the Exercise Price shall be required if such adjustment is less than $0.01; provided, however, that any adjustments that by reason of this Section 9(e) are not required to be made shall be carried forward and taken into account for purposes of any subsequent adjustment.

(g) Adjustment of Number of Shares. Upon each adjustment in the Exercise Price pursuant to this Section 9, the number of Warrant Shares purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Warrant Shares purchasable immediately prior to such adjustment by a fraction, (i) the numerator of which shall be the Exercise Price immediately prior to such adjustment, and (ii) the denominator of which shall be the Exercise Price immediately thereafter.

(h) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company will promptly deliver to the Holder a certificate executed by the Company’s Chief Financial Officer setting forth, in reasonable detail, the event requiring such adjustment and the method by which such adjustment was calculated, the adjusted Exercise Price and the adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable). The Company will retain at its office copies of all such certificates and cause the same to be available for inspection at said office during normal business hours by the Holder or any prospective purchaser of the Warrant designated by the Holder.

(i) Notice of Corporate Events. If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any subsidiary of the Company, or (ii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction at least 15 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to ensure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

10. Fractional Shares. The Company shall not be required to issue or cause to be issued fractional Warrant Shares on the exercise of this Warrant. If any fraction of a Warrant Share would, except for the provisions of this Section, be issuable upon exercise of this Warrant, the Company shall make a cash payment to the Holder equal to (a) such fraction multiplied by (b) the Market Price on the Exercise Date of one full Warrant Share.

-6-

11. Restricted Securities. The Holder represents and warrants that it (i) understands that the Warrant and the Warrant Shares have not been registered under the Securities Act and (ii) understands the restrictions set forth on the legend printed on the face of this Warrant.

12. Reserved.

13. Remedies. The Company stipulates that the remedies at law of the Holder of this Warrant in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

14. Notices. Any and all notices or other communications or deliveries hereunder (including without limitation any Exercise Notice) shall be in writing and shall be mailed by certified mail, return receipt requested, or by a nationally recognized courier service or delivered (in person or by facsimile), against receipt to the party to whom such notice or other communication is to be given. The address for such notices or communications shall be as set forth in the Subscription Agreement entered into by the Holder and the Company. Any notice or other communication given by means permitted by this Section 14 shall be deemed given at the time of receipt thereof.

15. Warrant Agent. The Company’s transfer agent shall also serve as warrant agent under this Warrant. Upon 30 days’ notice to the Holder, the Company may appoint a new warrant agent. Any Person into which any new warrant agent may be merged, any Person resulting from any consolidation to which any new warrant agent shall be a party or any Person to which any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register.

16. Miscellaneous.

(a) This Warrant may be assigned by the Holder. This Warrant shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or cause of action under this Warrant. This Warrant may be modified, revised or amended only in writing signed by the Company and at least two-third (2/3) of the Holders of such Warrants and their successors and assigns; provided, however, that no such modification, revision or amendment shall materially and adversely treat one or more Holders in a manner that is disproportionate to such treatment of any of the other Holders.

(b) The Company will not, by amendment of its governing documents or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment. Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any Warrant Shares above the amount payable therefor upon exercise thereof, (ii) will take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on the exercise of this Warrant, free from all taxes, liens, claims and encumbrances and (iii) will not close its shareholder books or records in any manner that interferes with the timely exercise of this Warrant.

-7-

(c) The validity, construction and enforcement of this Warrant shall be governed by the laws of the State of Delaware and jurisdiction is hereby vested in the Courts of said State in the event of the institution of any legal action under this Warrant; provided, however, in the event that any legal proceeding is brought against the Maryland Venture Fund (Department of Business and Economic Development of the State of Maryland, or the State of Maryland in connection with such entity’s investment hereunder, the parties to any such dispute agree to submit to the venue of the Maryland courts for purposes of resolving any and all such disputes.

(d) Neither party shall be deemed in default of any provision of this Warrant, to the extent that performance of its obligations or attempts to cure a breach hereof are delayed or prevented by any event reasonably beyond the control of such party, including, without limitation, war, hostilities, acts of terrorism, revolution, riot, civil commotion, national emergency, strike, lockout, unavailability of supplies, epidemic, fire, flood, earthquake, force of nature, explosion, embargo, or any other Act of God, or any law, proclamation, regulation, ordinance, or other act or order of any court, government or governmental agency, provided that such party gives the other party written notice thereof promptly upon discovery thereof and uses reasonable best efforts to cure or mitigate the delay or failure to perform.

(e) The headings herein are for convenience only, do not constitute a part of this Warrant and shall not be deemed to limit or affect any of the provisions hereof.

(f) In case any one or more of the provisions of this Warrant shall be deemed invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision that shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Warrant.
