Section 1.2Additional Definitions.

In addition to the foregoing, capitalized terms used in this Agreement and not otherwise defined in this Article I shall have the meanings so given to such terms herein.

ARTICLE II
REGISTRATION RIGHTS

Section 2.1Registration Rights.

(a) Effectiveness Deadline. The Company shall (i), within seven (7) days following the filing of the Company's Annual Report on Form 10-K for the year ended December 31, 2013

with the SEC (and in no event later than March 31, 2014), file with the SEC a Shelf Registration Statement to cover resales of the Registrable Securities by the holders of such Registrable Securities and (ii) use its reasonable best efforts to have such Shelf Registration Statement declared effective within 60 days after the Closing Date. The Company agrees that no Person other than holders of such Registrable Securities shall be permitted to sell shares of Common Stock or other securities pursuant to the Shelf Registration Statement contemplated hereby. In addition, the Company shall, promptly after the completion of any sale of Option Shares and/or Option Notes (as such terms are defined in the Securities Purchase Agreement) to the Investors, take all action necessary to file an amendment to the Shelf Registration Statement (if such Shelf Registration Statement has previously been filed with the SEC) to register such Option Shares and/or Option Notes (including any Conversion Shares).

(b) Failure to Meet Effectiveness Deadline. In addition to any other rights or remedies provided herein if the Shelf Registration Statement referred to in Section 2(a) above has not been timely filed with the SEC in accordance with Section 2(a), declared effective by the SEC within 60 days after the Closing Date or the Company fails to maintain the effectiveness of such Shelf Registration Statement pursuant to the terms contained in this Agreement, then the Company shall pay an increased interest rate on the Convertible Notes of (i) for the first three months after such violation occurs and is continuing, 0.25% per month, (ii) ) for each of the fourth through sixth month after such violation occurs and is continuing, 0.50% per month and (iii) for any time period beginning on the seventh month after such violation occurred and is continuing, 1.00% per month. Such additional interest will be capitalized by adding to the Outstanding Principal Amount from time to time of the Convertible Notes. Payment of such increased interest rate by the Company shall be in addition to, and shall not limit, the other remedies available to the Investor in the event that the Company does not comply with this Section 2 with respect to the filing and effectiveness of the registration statement referred to herein.

(c) Registration Termination Date; Delay. Once  the Shelf Registration Statement filed pursuant to Section 2(a) becomes effective, the Company shall file all reports, financial statements and other documents necessary to keep such Shelf Registration Statement current and the registration in effect until no Registrable Securities remain outstanding (the “Effective Period”); provided,  however that at any time during the Effective Period, the Company may determine, in the good faith judgment of its Board of Directors, after consultation with the Company's legal counsel, that offers and sales under the Shelf Registration Statement shall be suspended if (i) it is in the best interests of the Company not to disclose the existence of material facts surrounding any proposed or pending acquisition, disposition, strategic alliance or financing transaction involving the Company, the existence of which the Company has a bona fide business purpose for keeping confidential and the nondisclosure of which in the Shelf Registration Statement would reasonably be expected to cause the Shelf Registration Statement to fail to comply with applicable disclosure requirements or (ii) the Company is obligated to file a post-effective amendment to the Shelf Registration Statement to add Option Shares and/or Option Notes (an "Option Suspension").  Immediately upon making such a determination, the Company shall give notice to the holders of such Registrable Securities (a “Materiality Notice”), upon receipt of which each such holder agrees that it will immediately discontinue offers and sales of Registrable Securities under the Shelf Registration Statement until such holder receives copies of a supplemented or amended prospectus that corrects the

misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective; provided, that the Company may delay, suspend or withdraw the Registration Statement for such reason for no more than 30 days after the abandonment or consummation of any of the foregoing negotiations, transactions, events or offerings or, in any event, for not more than 60 days after delivery of the Materiality Notice at any one time during any period of 12 consecutive months (and the Company shall not be entitled to deliver a Materiality Notice at any time within 90 days of any prior termination of any suspension pursuant to a prior Materiality Notice); provided further, that any Option Suspension shall not count again the 60-day limitation during any 12 consecutive month period. If so directed by the Company, each holder of Registrable Securities will deliver to the Company all copies of the prospectus covering the Registrable Securities current at the time of receipt of a Materiality Notice.

Section 2.2Registration Procedures.

(a)When the Company is required by the provisions of this Agreement to effect the registration of shares of Registrable Securities, the Company shall:

(i)prepare and file with the Commission a Shelf Registration Statement (advance draft copies of which shall be furnished to the holders of Registrable Securities to be included in such Shelf Registration Statement and their respective counsel as expeditiously as possible prior to the filing thereof with the SEC) with respect to such shares and use its reasonable best efforts to cause such Shelf Registration Statement to become and remain effective for the Effective Period as described in Section 2.1(c) hereof;

(ii)prepare and file with the SEC such amendments and supplements to such Shelf Registration Statement and the prospectuses used in connection therewith as may be necessary to keep such Shelf Registration Statement effective and current during the Effective Period and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all shares covered by such Shelf Registration Statement, including such amendments and supplements as may be necessary to reflect the intended method of disposition from time to time of the holder or holders of Registrable Securities who have requested that any of their shares be sold or otherwise disposed of in connection with the registration (collectively, the “Prospective Sellers”) or to correct or update any misstatements or omissions which, if not corrected or updated, would reasonably be expected to cause the Registration Statement or the prospectuses used in connection therewith to fail to comply with applicable disclosure requirements;

(iii)furnish to each Prospective Seller such number of copies of each prospectus, including preliminary prospectuses and amendments and supplements to any prospectus, or any free writing prospectus related thereof, in conformity with the requirements of the Securities Act, and such other documents as the Prospective Seller may reasonably request in order to facilitate the public sale or other disposition of the shares owned by it;

(iv)if applicable, register or qualify the shares covered by such Shelf Registration Statement under such other securities or blue sky or other applicable laws of such jurisdictions as each Prospective Seller shall reasonably request to enable such seller to

consummate the public sale or other disposition of the shares owned by such seller, provided that the Company shall not be required in connection therewith or as an election thereto to qualify to do business or to file a general consent to service of process in any such jurisdiction;

(v) promptly notify each Prospective Seller at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (x) the filing of the Shelf Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto or any free writing prospectus related thereto, and, with respect to such registration statement or any post-effective amendment thereto, when the same has become effective; and (y) any written comments from the SEC with respect to any filing referred to in clause (x) and any written request by the SEC for amendments or supplements to the Shelf Registration Statement or any prospectus or prospectus supplement thereto or any free writing prospectus related thereto;

(vi)the Company shall permit counsel for the Prospective Sellers to review the Shelf Registration Statement and all amendments and supplements thereto (as well as all requests for acceleration or effectiveness thereof) a reasonable period of time prior to their filing with the SEC, and not file any document in a form to which such counsel reasonably objects and will not request acceleration of the Shelf Registration Statement without prior notice to such counsel;

(vii)[reserved]

(viii)provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such Shelf Registration Statement;

(ix)enter into such customary agreements and take all such other customary actions as the holders of a majority of the Registrable Securities being sold reasonably request in order to expedite or facilitate the disposition of such Registrable Securities;

(x)make available for inspection by any Prospective Seller and any attorney, accountant or other agent retained by any such Prospective Seller, all reasonable financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent public accountants who have certified the Company’s financial statements included in the Registration Statement to supply all information reasonably requested by any such seller, attorney, accountant or agent in connection with the preparation of such Registration Statement;

(xi)permit any Prospective Seller who, in the reasonable judgment of the Company upon advice of counsel, might be deemed to be an underwriter or controlling person of the Company, to participate in the preparation of such Registration Statement;

(xii)provide written notice to each Prospective Seller as soon as the Company becomes aware of any misstatements or omissions which, if not corrected or updated, would reasonably be expected to cause the Shelf Registration Statement or the prospectuses used in connection therewith to fail to comply with applicable disclosure requirements;

(xiii)in the event of the issuance of any stop order suspending the effectiveness of the Shelf Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the registration or qualification of any Registrable Securities included in such Shelf Registration Statement for sale in any jurisdiction where such shares had previously been registered or qualified upon the request of a Prospective Seller, use its reasonable best efforts to promptly obtain the withdrawal of such order;

(xiv)the Company shall otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder; and

(xv)the Company shall take all other reasonable actions necessary to expedite and facilitate disposition by each Investor of its Registrable Securities pursuant to the Shelf Registration Statement.

(b)Each Prospective Seller of Registrable Securities shall furnish to the Company such information as the Company may reasonably require from the Prospective Seller for inclusion in the Shelf Registration Statement (and the prospectus included therein).

(c)The Prospective Sellers shall not effect sales of the shares covered by the Shelf Registration Statement after receipt of facsimile or other written notice from the Company to suspend sales to permit the Company to correct or update, including to add Option Shares or Option Notes, the Shelf Registration Statement or prospectus until such Investor receives copies of a supplemented or amended prospectus that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective.

(d)The Company shall have no obligation to provide an underwritten offering for the holders of Registrable Securities to dispose of their shares.

Section 2.3Registration Expenses.

The Company shall pay all registration expenses relating to the Shelf Registration Statement filed hereunder including all registration and filing fees, exchange listing fees, printing expenses, fees and disbursements of counsel for the Company, state blue sky fees and expenses and the expense of any special audits incident to or required by any such registration, but shall exclude Selling Expenses.  As used herein, the term “Selling Expenses” shall mean, collectively, any selling commissions, brokerage fees and the fees and expenses of counsel for each holder of Registrable Securities.  Selling Expenses shall be borne by the respective seller thereof, in proportion to the respective number of shares of Registrable Securities sold by each of them.

Section 2.4Prospective Seller's Obligations.

Each Prospective Seller agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Prospective Seller not misleading and any other information regarding such Prospective Seller and the distribution of the Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Prospective Seller shall constitute a representation and warranty by such Prospective Seller that the information relating

to such Prospective Seller and its plan of distribution is as set forth in the prospectus delivered by such Prospective Seller in connection with such disposition, that such prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Prospective Seller or its plan of distribution and that such prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Prospective Seller or its plan of distribution necessary in order to make the statements in the prospectus, in the light of the circumstances under which they were made, not misleading.

Section 2.5Indemnification.

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement and notwithstanding any other remedy, indemnify, defend, protect and hold harmless the Investor, the stockholders, owners, officers, directors, partners, members, agents, employees and affiliates of each of them, each Person who controls the Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the stockholders, owners, officers, directors, partners, members, agents, employees and affiliates of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all Losses, promptly as incurred, arising out of or relating to (i) any untrue or alleged untrue statement of a material fact contained in the Shelf Registration Statement, any prospectus or any form of Company prospectus or in any amendment or supplement thereto, in any Company preliminary prospectus, or any free writing prospectus utilized in connection therewith, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, or any free writing prospectus, in the light of the circumstances under which they were made) or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which the Registrable Securities are offered not misleading, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding the Investor furnished in writing to the Company by the Investor for use therein, or to the extent that such information relates to the Investor or the Investor’s proposed method of distribution of Registrable Securities, (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Shelf Registration Statement, or (iii) any violation of this Agreement. The Company shall notify the Investor promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the Agreement.

(b) Indemnification by Investor. The Investor shall indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in the Shelf Registration Statement, any prospectus, or any form of prospectus, or in any amendment or supplement thereto, or any free writing prospectus utilized in connection therewith, or arising solely out of any omission of a material fact required

to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, or any free writing prospectus, in the light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished by the Investor in writing to the Company specifically for inclusion in the Shelf Registration Statement or such prospectus. In no event shall the liability of the Investor hereunder be greater in amount than the dollar amount of the net proceeds received by the Investor upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any action, suit, investigation, or proceeding (including, without limitation, an investigation or partial proceeding, such as a deposition), whether commenced in writing (“Proceeding”) shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party). It being understood, however, that the Indemnifying Party shall not, in connection with any one such Proceeding be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties; provided, however, that in the case a single firm of attorneys would be inappropriate due to actual or potential differing interests or conflicts between such Indemnified Parties and any other party represented by such counsel in such Proceeding or otherwise, then the Indemnifying Party shall be liable for the fees and expenses of one additional firm of attorneys with respect to such Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement

includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 2.5) shall be paid to the Indemnified Party, as incurred, within ten (10) Business Days of written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder.

(d) Contribution. If any indemnification to which an Indemnified Party is entitled under the terms of Section 2.5(a) or (b) is unavailable to such Indemnified Party (by reason of public policy or otherwise) or indemnification is otherwise available to an Indemnified Party pursuant to Section 2.5(c), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 2.5(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 2.5 was available to such party in accordance with its terms. As used herein, the term “Losses” means any and all losses, claims, damages, liabilities, settlement costs and expenses, including, without limitation, costs of preparation and reasonable attorneys’ fees.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.5, the Investor shall not be required to contribute any amount in excess of the amount by which the net proceeds actually received by the Investor from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that the Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section 2.5 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

Section 2.6Information Requirements.    

(a) The Company covenants that, if at any time before the termination of the Effective Period it is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Investor and take such further reasonable action as any Investor may reasonably request in writing (including, without limitation, making such reasonable representations as any such Investor may reasonably request), all to the extent required from time to time to enable such Investor to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and Rule 144A under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any Investor, the Company shall deliver to such Investor a written statement as to whether it has complied with such filing requirements, unless such a statement has been included in its most recent report filed pursuant to Section 13 or Section 15(d) of Exchange Act.

(b) The Company shall file the reports required to be filed by it under the Exchange Act and shall comply with all other requirements set forth in the instructions to Form S-3 (or such other form as may be applicable) in order to allow it to be eligible to file registration statements on Form S-3 (or such other form as may be applicable).

Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement.
