The Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Form 10-K or 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures in accordance with Item 307 of Regulation S-K

under the Securities Act for the Company’s most recently ended fiscal quarter or fiscal year-end (such date, the “Evaluation Date”) . The Company presented in its most recently filed Form 10-K or Form 10-Q the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) or, to the Company’s knowledge, in other factors that would materially affect the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)).

(t) Solvency . Based on the financial condition of the Company as of the Closing Date (and assuming that the Closing shall have occurred), (i) the Company’s fair saleable value of its assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

(u) Certain Fees . Except for fees payable to Roth Capital Partners, LLC (the “Placement Agent”) in connection with the transaction contemplated by this Agreement, no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. The Investors shall have no obligation with respect to any fees or with respect to any claims made by the Placement Agent or by or on behalf of any other Person other than the Placement Agent for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by this Agreement unless such Investor shall have entered into a written agreement with such Person regarding such fees.

(v) Certain Registration Matters . Assuming (i) the accuracy of the Investors’ representations and warranties set forth in Section 3.2(b)-(e), and (ii) none of the Insiders or the Placement Agent is subject to any Disqualification Event except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) and (iv) the Insiders and the Placement Agent have complied with the “bad actor” disclosure requirements set forth in Rule 506(e) of Regulation D, no registration under the Securities Act is required for the offer and sale of the Shares and Warrants and the offer of the Warrant Shares by the Company to the Investors under the Transaction Documents. Subject to Schedule 3.1(v) , the Company is eligible to register its Common Stock for resale by the Investors under Form S-3 promulgated under the Securities Act. Except as specified in the SEC reports, the Company has not granted or agreed to grant to any Person other than the Investors pursuant to the Registration Rights Agreement any rights (including “piggy-back” registration rights) to have any securities of the Company registered with the Commission or any other governmental authority that have not been satisfied through an effective registration statement or by waiver of such rights.

(w) Listing and Maintenance Requirements . The Company has not, in the two years preceding the date hereof, received notice from any Trading Market to the effect that the Company is not in compliance with the listing or maintenance requirements thereof. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with the listing and maintenance requirements for continued listing of the Common Stock on the Trading Market on which the Common Stock is currently listed or quoted.

(z) No Additional Agreements . The Company does not have any agreement or understanding with any Investor with respect to the transactions contemplated by the Transaction Documents other than as specified in the Transaction Documents.

(aa) Accountants .

(a) Organization; Authority . Such Investor is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate, partnership, limited liability company or other applicable like power and authority to enter into and to consummate the transactions contemplated by the applicable Transaction Documents and otherwise to carry out its obligations thereunder. The execution, delivery and performance by such Investor of the applicable Transaction Documents and the transactions contemplated by this Agreement has been duly authorized by all necessary corporate or, if such Investor is not a corporation, such partnership, limited liability company or other applicable like action, on the part of such Investor. Each of this Agreement and the Registration Rights Agreement has been duly executed by such Investor, and when delivered by such Investor in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Investor, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.

(b) Investment Intent . Such Investor is acquiring the Securities for its own account and not with a view to or for distributing or reselling such Securities or any part thereof, without prejudice, however, to such Investor’s right at all times to sell or otherwise dispose of all or any part of such Securities in compliance with applicable federal and state securities laws. Subject to the immediately preceding sentence, nothing contained herein shall be deemed a representation or warranty by such Investor to hold the Securities for any period of time. Such Investor is acquiring the Securities hereunder in the ordinary course of its business. Such Investor does not have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities.

(c) Investor Status . At the time such Investor was offered the Securities, it was, and at the date hereof it is, and on each date on which it exercises Warrants it will be, an “accredited investor” as defined in Rule 501(a) under the Securities Act. Such Investor is not a registered broker-dealer under Section 15 of the Exchange Act. Such Investor has such experience in business and financial matters that it is capable of evaluating the merits and risks of an investment in the Securities. Such Investor acknowledges that an investment in the Securities is speculative and involves a high degree of risk.

(d) General Solicitation . Such Investor is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

(e) Access to Information . Such Investor acknowledges that it has reviewed the Disclosure Materials and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and the Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of such Investor or its representatives or counsel shall modify, amend or affect such Investor’s right to rely on the truth, accuracy and completeness of the Disclosure Materials and the Company’s representations and warranties contained in the Transaction Documents.

(f) Certain Trading Activities . Such Investor has not directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Investor, engaged in any transactions in the securities of the Company (including, without limitations, any Short Sales involving the Company’s securities) since the time that such Investor was first contacted by the Company or the Placement Agent regarding the transactions contemplated by this Agreement. Such Investor covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will engage in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions contemplated by this Agreement are publicly disclosed on the Trading Day following the execution of this Agreement in accordance with Section 4.5.

(g) Limited Ownership . The purchase by such Investor of the Shares and Warrants issuable to it at the Closing will not result in such Investor (individually or together with any other Person with whom such Investor has identified, or will have identified, itself as part of a “group” in a public filing made with the Commission involving the Company’s securities) acquiring, or obtaining the right to acquire, in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a post transaction basis that assumes that the Closing shall have occurred. Such Investor does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired, or obtained the right to acquire, as a result of the Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a post transaction basis that assumes that the Closing shall have occurred.

(h) Independent Investment Decision . Such Investor has independently evaluated the merits of its decision to purchase Securities pursuant to the Transaction Documents, and such Investor confirms that it has not relied on the advice of any other Investor’s business and/or legal counsel in making such decision. Such Investor has not relied on the business or legal advice of Roth Capital Partners, LLC or any other placement agent or any of their respective agents, counsel or Affiliates in making its investment decision hereunder, and confirms that none of such Persons has made any representations or warranties to such Investor in connection with the transactions contemplated by the Transaction Documents.

(i) No Disqualification Events . Neither the Investor nor, to the extent it has them, any of its shareholders, members, managers, general or limited partners, directors, affiliates or executive officers, are subject to any Disqualification Event, except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3). The purchase of the Securities by the Investor will not subject the Company to any Disqualification Event.

The Company acknowledges and agrees that no Investor has made or makes any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2.

ARTICLE 4.

OTHER AGREEMENTS OF THE PARTIES

4.1. (a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of the Securities other than pursuant to an effective registration statement, to the Company, to an Affiliate of an Investor or in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act.

(b) Certificates evidencing Securities will contain the following legend, until such time as they are not required under Section 4.1(c):

[NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED] [THESE SECURITIES HAVE 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 ANY APPLICABLE STATE SECURITIES LAWS 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. [THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES] [THESE SECURITIES] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT SECURED BY SUCH SECURITIES.

The Company acknowledges and agrees that an Investor may from time to time pledge, and/or grant a security interest in some or all of the Securities pursuant to a bona fide margin agreement in connection with a bona fide margin account and, if required under the terms of such agreement or account, such Investor may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer following default by the Investor transferee of the pledge. No notice shall be required of such pledge. At the appropriate Investor’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer thereof including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling shareholders thereunder. Except as otherwise provided in Section 4.1(c), any Securities subject to a pledge or security interest as contemplated by this Section 4.1(b) shall continue to bear the legend set forth in this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a).

(c) Certificates evidencing Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b)): (i) while a registration statement (including the Registration Statement) covering such Shares and Warrant Shares is then effective, or (ii) following a sale or transfer of such Shares or Warrant Shares pursuant to Rule 144 (assuming the transferee is not an Affiliate of the Company), or (iii) after a period of six months has elapsed since the later of the date the securities were acquired from the Company or from an Affiliate of the Company, while such Shares or Warrant Shares are eligible for sale by the selling Investor without volume restrictions under Rule 144, subject to receipt from such Investor requesting removal of such legends of a representation letter, in a form reasonably acceptable to the Company, subject to the requirement, to the extent then required for such Shares or Warrant Shares to be resold by such Investor under Rule 144, that the adequate current public information requirement of Rule 144(c) is met at the time of sale. The transfer agent’s fees and any fees of the Company’s legal counsel associated with removal of such legend shall be borne by the Company. In the event the legend set forth in Section 4.1(b) has been removed pursuant to clause (i) above, each Investor agrees to sell such Shares or Warrant Shares only pursuant to an effective registration statement (including the Registration Statement), or in a transaction not subject to the registration requirement of the Securities Act and in accordance with applicable state securities laws as evidenced by a legal opinion of counsel to the Investor to such effect, the substance of which shall be reasonably acceptable to the Company. Each investor acknowledges and agrees that the Shares and the Warrant Shares remain “restricted securities” as such term is defined in Rule 144 notwithstanding removal of the legend set forth in Section 4.1(b) until such Shares and Warrant Shares are sold or transferred under an effective registration statement (including the Registration Statement) or under Rule 144. The Company agrees that following the Effective Date or such other time as legends are no longer required to be set forth on certificates representing Shares and Warrant Shares under this Section 4.1(c), it

will, no later than three Trading Days following the delivery by an Investor to the Company or the transfer agent of a certificate representing such Shares or Warrant Shares containing a restrictive legend, deliver or cause to be delivered to such investor Shares or Warrant Shares which are free of all restrictive and other legends. If the Company is then eligible, certificates for Shares and Warrant Shares subject to legend removal hereunder shall be transmitted by the transfer agent to an Investor by crediting the prime brokerage account of such Investor with the Depository Trust Company System as directed by such Investor. If an Investor shall make a sale or transfer of Shares or Warrant Shares either (x) pursuant to Rule 144 or (y) pursuant to a registration statement and in each case shall have delivered to the Company or the Company’s transfer agent the certificate representing the applicable Shares or Warrant Shares containing a restrictive legend which are the subject of such sale or transfer and a representation letter in customary form (the date of such sale or transfer and Shares or Warrant Share delivery being the “Share Delivery Date”) and (1) the Company shall fail to deliver or cause to be delivered to such Investor a certificate representing such Shares or Warrant Shares that is free from all restrictive or other legends by 6:00 p.m. (New York City time) on the third Trading Day following the Share Delivery Date and (2) following such third Trading Day after the Share Delivery Date and prior to the time such Shares or Warrant Shares are received free from restrictive legends, the Investor, or any third party on behalf of such Investor, purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Investor of such Shares or Warrant Shares (a “ Buy-In” ), then, in addition to any other rights available to the Investor under the Transaction Documents and applicable law, the Company shall pay in cash to the Investor (for costs incurred either directly by such Investor or on behalf of a third party) the amount by which the total purchase price paid for Common Stock as a result of the Buy-In (including brokerage commissions, if any) exceed the proceeds received by such Investor as a result of the sale to which such Buy-In relates. The Investor shall provide the Company written notice indicating the amounts payable to the Investor in respect of the Buy-In. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section.

4.2. Furnishing of Information . As long as any Investor owns any Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. As long as any Investor owns Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to the Investors and make publicly available in accordance with Rule 144(c) such information as is required for the Investors to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell the Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144.

4.3. Integration. The Company shall not, and shall use its best efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Investors, or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market in a manner that would require shareholder approval of the sale of the securities to the Investors.

4.4. Subsequent Registrations . Other than a Registration Statement pursuant to the Registration Rights Agreement, prior to the first to occur of (a) the Effective Date of a Registration Statement resulting in all Registrable Securities (as defined in the Registration Rights Agreement) other than Cut Back Shares (as defined in the Registration Rights Agreement) being registered for resale pursuant to one or more effective Registration Statements or (b) such time as all Registrable Securities may be sold by the Investors without volume restrictions pursuant to Rule 144, the Company may not file any registration statement (other than on Form S-8, S-4 or any registration statement filed pursuant to the agreements specified in Schedule 4.4 ) with the Commission with respect to any securities of the Company; provided, however, that, for the avoidance of doubt, so long as all Registrable Securities other than Cut Back Shares are registered for resale pursuant to one or more effective Registration Statements, the Company may file a registration statement of any type with the Commission with respect to securities of the Company notwithstanding that any Cut Back Shares have not been registered for resale pursuant to one or more effective Registration Statements.

4.5. Securities Laws Disclosure; Publicity . By 9:00 a.m. (New York City time) on the Trading Day following the execution of this Agreement, and by 9:00 a.m. (New York City time) on the Trading Day following the Closing Date, the Company shall issue press releases disclosing the transactions contemplated hereby and the Closing, respectively. On the Trading Day following the execution of this Agreement the Company will file a Current Report on Form 8-K disclosing the material terms of the Transaction Documents (and attach as exhibits thereto the Transaction Documents), and on the Trading Day following the Closing Date the Company will file an additional Current Report on Form 8-K to disclose the Closing. Following the public disclosure referenced above, in each case, after the Company has issued both a press release and filed a Current Report on Form 8-K, no Investor will be in possession of material, non-public information provided to such Investor by the Company or anyone acting on behalf of the Company and no Investor will have a duty of confidentiality with respect to such information. In addition, the Company will make such other filings and notices in the manner and time required by the Commission and the Trading Market on which the Common Stock is listed, including, without limitation, a NASDAQ Listing of Additional Shares Notification (if required). Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Investor, or include the name of any Investor in any filing with the Commission (other than a Registration Statement and any exhibits to filings made in respect of this transaction in accordance with periodic filing requirements under the Exchange Act) or any regulatory agency or Trading Market, without the prior written consent of such Investor, except to the extent such disclosure is required by law or Trading Market regulations.

4.6. Limitation on Issuance of Future Priced Securities . From the date hereof until the date that is 6 months after the Effective Date, the Company shall not issue any “Future Priced Securities” as such term is described by NASDAQ IM-5635-4.

4.7. Indemnification of Investors . In addition to the indemnity provided in the Registration Rights Agreement, the Company will indemnify and hold the Investors and their respective directors, officers, shareholders, partners, employees and agents (each, an “Investor Party” ) harmless from any and all out of pocket losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation (collectively,

“Losses” ) that any such Investor Party may suffer or incur as a result of or relating to any material breach of any representation, warranty, covenant or agreement made by the Company in any Transaction Document. In addition to the indemnity contained herein, the Company will reimburse each Investor Party for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 4.7 shall be the same as those set forth in Section 5 of the Registration Rights Agreement.

4.8. Non-Public Information . The Company covenants and agrees that neither it nor any other Person acting on its behalf will provide any Investor or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Investor shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Investor shall be relying on the foregoing representations in effecting transactions in securities of the Company.

4.9. Listing of Shares and Warrant Shares . The Company agrees, (i) if the Company applies to have the Common Stock traded on any Trading Market other than the Trading Market on which the Common Stock is traded as of the date of this Agreement, it will include in such application the Shares and Warrants Shares, and will take such other action as is necessary or desirable to cause the Shares and Warrants Shares to be listed on such other Trading Market as promptly as possible, and (ii) it will take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market.

4.10. Use of Proceeds. The Company will use the net proceeds from the sale of the Securities to repay existing debt, for working capital purposes and the development of a residential leasing platform, and not for the redemption of any Common Stock or Common Stock Equivalents.

4.11. Subsequent Equity Sales . From the date hereof until the date that is 30 days after the Effective Date, without the prior written consent of the Placement Agent, the Company shall not issue shares of Common Stock or Common Stock Equivalents; provided, however, the 30-day period set forth in this Section 4.11 shall be extended for the number of Trading Days during such period in which (i) trading in the Common Stock is suspended by any Trading Market within such 30-day period, or (ii) within 30 days after the Effective Date of the Initial Registration Statement, the Registration Statement is not effective or the prospectus included in the Registration Statement may not be used by the Investors for the resale of the Shares and Warrant Shares (other than Cut Back Shares). Notwithstanding the foregoing, in no event shall this Section 4.11 prohibit the Company from issuing shares of Common Stock or Common Stock Equivalents (i) in connection with acquisitions or strategic transactions approved by a majority of the disinterested directors of the Company, including, without limitation, acquisitions and strategic transaction disclosed in the SEC Reports as of the date hereof, provided that any such issuance shall only be to a Person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives 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, (ii) upon the exercise of any options or warrants outstanding on the date hereof, (iii) upon the exercise of the Warrants, (iv) to employees, directors or consultants pursuant to any stock option or equity incentive or employee stock purchase plan, or (v) upon the conversion of any indebtedness owed to Riverside Renewable Energy Investments, LLC or its affiliates outstanding on the date hereof, whether convertible or not on the date hereof, provided that any Common Stock issued upon such conversion shall be valued at no less than the Per Share Purchase Price.

Upon a termination in accordance with this Section 6.5, the Company and the terminating Investor(s) shall not have any further obligation or liability (including as arising from such termination) to the other and no Investor will have any liability to any other Investor under the Transaction Documents as a result therefrom.

6.9. Governing Law . All questions concerning the construction, validity, enforcement and interpretation of this Agreement 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 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, employees or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts 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 the any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

6.10. Survival . The representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery of the Securities.

6.11. Execution . This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. 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.

6.12 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.

6.13. Rescission and Withdrawal Right . Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Investor exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Investor may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

6.14. Replacement of Securities . If any certificate or instrument evidencing any Securities 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. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. Notwithstanding the foregoing, the terms of the Warrants shall govern the replacement, exchange and substitution of the Warrants.

6.15. Remedies . In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Investors and the Company will be entitled to specific performance under the Transaction Documents. The parties hereto 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.

6.16. Payment Set Aside . To the extent that the Company makes a payment or payments to any Investor pursuant to any Transaction Document or an Investor enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any

law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.17. Independent Nature of Investors’ Obligations and Rights . The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Securities pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor.

6.18. Limitation of Liability . Notwithstanding anything herein to the contrary, the Company acknowledges and agrees that the liability of an Investor arising directly or indirectly, under any Transaction Document of any and every nature whatsoever shall be satisfied solely out of the assets of such Investor, and that no trustee, officer, other investment vehicle or any other Affiliate of such Investor or any investor, shareholder or holder of shares of beneficial interest of such an Investor shall be personally liable for any liabilities of such Investor.

6.19. Further Assurances . Each party hereto shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

2. Registration .

(a) On or prior to its applicable Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering the resale of all Registrable Securities not already covered by an existing and effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. Each Registration Statement required to be filed under this Agreement shall be filed on Form S-3 (or if the Company is not then eligible to utilize such form of registration, it shall utilize such other available form appropriate for such purpose) and contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement, other than as to the characterization of any Holder as an underwriter, which shall not occur without such Holder’s written consent) the “Plan of Distribution” attached hereto as Annex B . The Company shall cause each Registration Statement required to be filed under this Agreement to be declared effective under the Securities Act as soon as possible but, in any event, no later than its Effectiveness Date, and shall use its reasonable best efforts to keep each such Registration Statement continuously effective during its entire Effectiveness Period. By 5:00 p.m. (New York City time) on the Business Day immediately following the Effective Date of each Registration Statement, the Company shall file with the Commission in accordance with Rule 424 the final

3

prospectus to be used in connection with sales pursuant to such Registration Statement (whether or not such filing is technically required under such Rule). If for any reason other than due solely to SEC Restrictions, a Registration Statement is effective but not all outstanding Registrable Securities are registered for resale pursuant thereto, then the Company shall prepare and file by the applicable Filing Date an additional Registration Statement to register the resale of all such unregistered Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415.

(b) Notwithstanding anything to the contrary contained in this Section 2, if the Company receives Commission Comments, and following discussions with and responses to the Commission in which the Company uses its reasonable best efforts and time to cause as many Registrable Securities for as many Holders as possible to be included in the Registration Statement filed pursuant to Section 2(a) without characterizing any Holder as an underwriter (and in such regard uses its reasonable best efforts to cause the Commission to permit the affected Holders or their respective counsel to participate in Commission conversations on such issue together with Company Counsel, and timely conveys relevant information concerning such issue with the affected Holders or their respective counsel), the Company is unable to cause the inclusion of all Registrable Securities, then the Company may, following not less than three Trading Days prior written notice to the Holders (i) remove from the Registration Statement such Registrable Securities (the “ Cut Back Shares ”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities, in each case as the Commission may require in order for the Commission to allow such Registration Statement to become effective; provided , that in no event may the Company name any Holder as an underwriter without such Holder’s prior written consent (collectively, the “ SEC Restrictions ”). Unless the SEC Restrictions otherwise require, any cut-back imposed pursuant to this Section 2(b) shall be allocated among the Registrable Securities of the Holders on a pro rata basis. No registration delay payments under Section 2(c) shall accrue on or as to any Cut Back Shares, and the required Effectiveness Date for such Registration Statement will be tolled, until such time as the Company is able to effect the registration of the Cut Back Shares in accordance with any SEC Restrictions (such date, the “ Restriction Termination Date ”). From and after the Restriction Termination Date, all provisions of this Section 2 (including, without limitation, the registration delay payment provisions, subject to tolling as provided above) shall again be applicable to the Cut Back Shares (which, for avoidance of doubt, retain their character as “Registrable Securities”) so that the Company will be required to file with and cause to be declared effective by the Commission such additional Registration Statements in the time frames set forth herein as necessary to ultimately cause to be covered by effective Registration Statements all Registrable Securities.

(c) If: (i) a Registration Statement is not filed on or prior to its Filing Date covering the Registrable Securities required under this Agreement to be included therein (if the Company files a Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a) hereof, the Company shall not be deemed to have satisfied this clause (i)), or (ii) a Registration Statement is not declared effective by the Commission on or prior to its required Effectiveness Date or if by the Business Day immediately following the Effective Date, the Company shall not have filed a “final” prospectus for the Registration Statement with the Commission under Rule 424(b) in accordance with the terms hereof (whether or not such a prospectus is technically required by such Rule), or (iii) after its

4

Effective Date, without regard for the reason thereunder or efforts therefor, such Registration Statement ceases for any reason to be effective and available to the Holders as to all Registrable Securities to which it is required to cover at any time prior to the expiration of its Effectiveness Period for more than an aggregate of 30 Trading Days (which need not be consecutive), or (iv) the Company fails, during the period from the six month anniversary of the Closing Date to the one year anniversary of the Closing Date, to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company pursuant to the Exchange Act, other than Form 8-K reports (any such failure or breach being referred to as an “Event,” and for purposes of clauses (i), (ii), or (iv) the date on which such Event occurs, or for purposes of clause (iii) the date which such 30 Trading Day-period is exceeded, being referred to as “Event Date” ), then in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial registration delay payments and not as a penalty, equal to the product of (x) the product of (A) 1.0% multiplied by (B) the quotient of (i) the number of such Holder’s Registrable Securities that are not then covered, but are required to be covered, by a Registration Statement that is then effective and available for use by such Holder divided by (ii) the total number of such Holder’s Registrable Securities multiplied by (y) the aggregate Investment Amount paid by such Holder for the Shares pursuant to the Purchase Agreement. The parties hereto agree that in no event will the Company be liable for any registration delay payments under this Agreement in excess of 1.0% of the aggregate Investment Amount of the Holders in any 30-day period and the maximum aggregate registration delay payments payable to a Holder under this Agreement shall be 10% of the aggregate Investment Amount paid by such Holder pursuant to the Purchase Agreement. The partial registration delay payments pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a month prior to the cure of an Event (except in the case of the first Event Date), and shall cease to accrue (unless earlier cured) upon the expiration of the Effectiveness Period. For the avoidance of doubt, in no event shall the Company be liable for registration delay payments with respect to Cut Back Shares.

(d) Each Holder agrees to furnish to the Company a completed Questionnaire in the form attached to this Agreement as Annex C (a “Selling Holder Questionnaire” ). The Company shall not be required to include the Registrable Securities of a Holder in a Registration Statement and shall not be required to pay any registration delay payments under Section 2(c) to any Holder who fails to furnish to the Company a fully completed Selling Holder Questionnaire at least two Trading Days prior to the Filing Date (subject to the requirements set forth in Section 3(a)).

3. Registration Procedures .

In connection with the Company’s registration obligations hereunder, the Company shall:

(a) (i) Not less than four Trading Days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto, the Company shall furnish to each Holder copies of the “Selling Stockholders” section of such document, the “Plan of Distribution” and any risk factor contained in such document that addresses specifically this

5

transaction or the Selling Stockholders, as proposed to be filed, which documents will be subject to the review of such Holder. Subject to Section 3(a)(ii) below, the Company shall not file a Registration Statement, any Prospectus or any amendments or supplements thereto in which the “Selling Stockholder” section thereof differs from the disclosure received from a Holder in its Selling Holder Questionnaire (as amended or supplemented). The Company shall not file a Registration Statement, any Prospectus or any amendments or supplements thereto in which it (a) characterizes any Holder as an underwriter, (b) excludes a particular Holder due to such Holder refusing to be named as an underwriter, or (c) reduces the number of Registrable Securities being registered on behalf of a Holder except pursuant to, in the case of subsections (b) or (c), the Commission Comments, without, in each case, such Holder’s express written authorization.

(ii) Each Holder acknowledges that the Commission’s staff takes the position that any selling stockholder who is a broker-dealer or an affiliate of a broker dealer must be identified as an underwriter in a resale registration statement. Notwithstanding anything to the contrary in this Agreement, upon receipt by the Company of Commission Comments requiring the Company to either exclude Registrable Securities held by a Holder or deem such Holder to be an underwriter with respect to Registrable Securities they seek to include in such Registration Statement, the Company shall not be required to include the Registrable Securities of such Holder in a Registration Statement and shall not be required to pay any registration delay payments under Section 2(c) to any such Holder that refuses to be identified as an underwriter in a Registration Statement. Notwithstanding the foregoing, a Holder that is an affiliate of a broker-dealer shall not be identified as an underwriter in a Registration Statement so long as the Holder represents to the Company that such holder (y) purchased the Registrable Securities being registered for resale in the ordinary course of business and (x) at the time of the purchase, the Holder had no agreements or understanding, directly or indirectly, with any person to distribute such Registrable Securities.

(b) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably possible provide the Holders true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that would not result in the disclosure to the Holders of material and non-public information concerning the Company; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statement(s) and the disposition of all Registrable Securities covered by each Registration Statement.

6

(c) Notify the Holders as promptly as reasonably possible (and, in the case of (i)(A) below, not less than three Trading Days prior to such filing and, in the case of (v) below, not less than three Trading Days prior to the financial statements in any Registration Statement becoming ineligible for inclusion therein) and (if requested by any such Person) confirm such notice in writing no later than one Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders that pertain to the Holders as a Selling Stockholder or to the Plan of Distribution, but not information which the Company believes would constitute material and non-public information); and (C) with respect to each Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) Use its reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

(e) Furnish to each Holder, upon request and without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Person (including those previously furnished) promptly after the filing of such documents with the Commission unless a requested document is available on EDGAR.

(f) Promptly deliver to each Holder, upon request and without charge, as many copies of each Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request unless a requested document is available on EDGAR.

(h) Cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement(s), which certificates shall be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request.

4. Registration Expenses . All fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement.

5. Indemnification .

(a) Indemnification by the Company . The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, investment advisors, partners, members and employees of each of them, each

8

Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all out of pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and expenses (collectively, “ Losses ”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, 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, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (1) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex B hereto for this purpose) or (2) in the case of an occurrence of an event of the type specified in Section 3(c)(ii)-(v), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of an Advice or an amended or supplemented Prospectus, but only if and to the extent that following the receipt of the Advice or the amended or supplemented Prospectus the misstatement or omission giving rise to such Loss would have been corrected. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b) Indemnification by Holders . Each Holder shall, severally and not jointly, 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 incurred, arising solely out of or based solely upon: (x) such Holder’s failure to comply with the prospectus delivery requirements of the Securities Act or (y) any untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising solely out of or based solely upon any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading to the extent, but only to the extent that, (1) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement (it being understood that the Holder has approved Annex B hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 3(c)(ii)-(v), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or

9

defective and prior to the receipt by such Holder of an Advice or an amended or supplemented Prospectus, but only if and to the extent that following the receipt of the Advice or the amended or supplemented Prospectus the misstatement or omission giving rise to such Loss would have been corrected. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings . If any 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: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) 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 (3) 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). 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) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided , that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

10

(d) Contribution . If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), 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 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 was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 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 5(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

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

6. Miscellaneous .

(a) Remedies . In the event of a breach by the Company or by a Holder, of any of their respective obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b) No Piggyback on Registrations . Neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in a Registration Statement other than the Registrable Securities.

11

(c) Compliance . Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement.

The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

(e) Piggy-Back Registrations . If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, or a registration statement filed pursuant to either the Registration Rights Agreement, dated June 3, 2013, between the Company and the investors party thereto or the Underwriting Agreement, dated November 20, 2013, between the Company and the underwriter party thereto, then the Company shall send to each Holder written notice of such determination and, if within fifteen calendar days after receipt of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights and subject to the applicable terms of such registration rights.

(f) Amendments and Waivers . The provisions of this Agreement, including the provisions of this Section 6(f), may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders of no less than a majority in interest of the then outstanding Registrable Securities, and any amendment to any provision of this Agreement made in accordance with this Section shall be binding on all Investors and Holders, as applicable. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of certain Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority of the Registrable Securities to which such waiver or consent relates; provided , further that no amendment or waiver to any provision of this Agreement relating to naming any Holder or requiring the naming of any Holder as an underwriter may be effected in any manner without such Holder’s prior written consent. Section 2(a) may not be amended or waived except by written consent of each Holder affected by such amendment or waiver.

Plan of Distribution

The Selling Stockholders and any of their pledgees, donees, transferees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or quoted or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling shares:

The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

The Selling Stockholders may from time to time pledge or grant a security interest in some or all of the Shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of Common Stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

Upon the Company being notified in writing by a Selling Stockholder that any material arrangement has been entered into with a broker-dealer for the sale of Common Stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such Selling Stockholder and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such the shares of Common Stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction. In addition, upon the Company being notified in writing by a Selling Stockholder that a donee or pledgee intends to sell more than 500 shares of Common Stock, a supplement to this prospectus will be filed if then required in accordance with applicable securities law.

The Selling Stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, that can be attributed to the sale of Securities will be paid by the Selling Stockholder and/or the purchasers. Each Selling Stockholder has represented and warranted to the Company that it acquired the securities subject to this Registration Statement in the ordinary course of such Selling Stockholder’s business and, at the time of its purchase of such securities such Selling Stockholder had no agreements or understandings, directly or indirectly, with any person to distribute any such securities.

The Company has advised each Selling Stockholder that it is the view of the Commission that it may not use shares registered on this Registration Statement to cover short sales of Common Stock made prior to the date on which this Registration Statement shall have been declared effective by the Commission. If a Selling Stockholder uses this prospectus for any sale of the Common Stock, it will be subject to the prospectus delivery requirements of the Securities Act. The Selling Stockholders will be responsible to comply with the applicable provisions of the Securities Act and Exchange Act, and the rules and regulations thereunder promulgated, including, without limitation, Regulation M, as applicable to such Selling Stockholders in connection with resales of their respective shares under this Registration Statement.

The Company is required to pay all fees and expenses incident to the registration of the shares, but the Company will not receive any proceeds from the sale of the Common Stock. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
