No executive officer, to the knowledge of the Company, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and the continued employment of each such executive officer does not subject the Company to any liability with respect to any of the foregoing matters.

Other than as set forth on Schedule 3.1(hh)(ii), the exercise in full of the Warrants (without regard to any limitations on exercise of the Warrants) will not result in any fundamental transaction, change of control or similar event, the requirement to make any payment (whether of cash or otherwise) or adjustment or issue any shares of Common Stock or other securities with respect to any fundamental transaction, change of control or similar event, or an event that with the passage of time could result in a fundamental transaction, change of control or similar event under any agreement (including, without limitation, any employment agreement), outstanding security (including, without limitation, any option or warrant to purchase Common Stock) or other instrument.

(ii) Shell Company Status. The Company is not and has never been, prior to the date hereof, an issuer subject to Rule 144(i) under the Securities Act.

(jj) Acknowledgment Regarding Purchaser’s Purchase of Securities. The Company acknowledges and agrees that each Purchaser is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Purchaser, together with its other Attribution Parties, is (i) an officer or director of the Company or the Subsidiary, (ii) assuming the accuracy of the Purchasers’ representation set forth in Section 3.2(g), an Affiliate of the Company or the Subsidiary or (iii) assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2(g), to the knowledge of the Company, a “beneficial owner” (as defined for purposes of Rule 13d-3 of the 0000 Xxx) of more than 10% of the aggregate number of shares of Common Stock currently outstanding. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company or the Subsidiary (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Purchaser or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Purchaser’s purchase of the Securities. The Company further represents to each Purchaser that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives.

(kk) U.S. Real Property Holding Corporation. The Company is not, has never been, and so long as any Securities remain outstanding, shall not become, a U.S. real property holding corporation within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended, and the Company shall so certify upon any Purchaser’s request.

(ll) Acknowledgement Regarding Buyers’ Trading Activity.

The Company further understands and acknowledges that one or more Purchasers may engage in hedging and/or trading activities (including long and short sales) at various times during the period that the Securities are outstanding. The Company acknowledges that such aforementioned hedging and/or trading activities (including long and short sales) do not constitute a breach of this Agreement, the Securities or any of the documents executed in connection herewith.

None of the Company, any of its predecessors, any affiliated issuer, any director, executive officer, other officer of the Company participating in the offering hereunder, any beneficial owner of 20% or more of the Company's outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the Securities Act) connected with the Company in any capacity at the time of sale (each, an "Issuer Covered Person" and, together, "Issuer Covered Persons") is subject to any of the "Bad Actor" disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a "Disqualification Event"). The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event.

(nn) Series D 2014 Documentation. No provision of any of the Series D 2014 Documentation or any other agreement relating thereto, restricts (x) any issuance, payment, the availability of any right or application of any obligation pursuant to this Agreement or any Transaction Document or (y) any issuance of Common Stock or Common Stock Equivalents.

3.2 Representations and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as of the date hereof and as of the Closing Date (unless as of a specific date therein) to the Company as follows:

(a) Organization; Authority. Such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate, partnership, limited partnership, limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by this Agreement and the other Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and the other Transaction Documents and performance by such Purchaser of the transactions contemplated by this Agreement and the other Transaction Documents have been duly authorized by all necessary corporate, partnership, limited partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b) Own Account. Such Purchaser (i) understands that the Securities are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account and not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities law, (ii) has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state securities law, and (iii) has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state securities law (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business.

(c) Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which it exercises any Warrants it will be, (i) an “accredited investor” as defined in Rule 501 under the Securities Act and (ii) either a “qualified institutional buyer” as defined in Rule 144A under the Securities Act or a “large institutional accredited investor”. Such Purchaser is not required to be registered as a broker-dealer under the Exchange Act.

(d) Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

(e) No Tax or Legal Advice. Such Purchaser understands that nothing in this Agreement, any other Transaction Document or any other materials presented to such Purchaser in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. Such Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities.

(f) General Solicitation. Such Purchaser 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. Such Purchaser has had a pre-existing relationship with the Company prior to contemplating an investment contemplated under these Transaction Documents.

(g) Condition of the Company; Independent Investigation. Such Purchaser acknowledges that it has concluded to its satisfaction its own independent investigation of the Company, its business and its assets and acknowledges that such Purchaser has been provided access to the personnel, properties, assets, premises, books and records and other documents and data of the Company for such purpose, including, without limitation, access to the SEC Reports. Such Purchaser acknowledges that it has made its own decision to consummate the transactions contemplated herein based on its independent review.

(h) Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement. Other than to other Persons party to this Agreement and the Purchaser’s employees, representatives and agents, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future.

The Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 Transfer Restrictions.

(a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement or Rule 144 (in connection with which the Company may require the Purchaser to provide reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144), 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. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Purchaser effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document.

(b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities in the following form:

THIS SECURITY HAS 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, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (B) PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY, OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

(c) Certificates evidencing the Shares and Warrant Shares, or the applicable portion thereof, shall not contain any legend (including the legend set forth in Section 4.1(b) hereof), (i) once a registration statement (including the Registration Statement) covering the resale of such Shares and the Warrant Shares is effective under the Securities Act, (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, or (iii) if such Shares or Warrant Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares and Warrant Shares and without volume or manner-of-sale restrictions. At the Purchaser’s request, for the applicable portion of the Shares and Warrant Shares, the Company shall cause its counsel to issue a legal opinion to the Transfer Agent within two (2) Trading Days after the Effective Date if required by the Transfer Agent to effect the removal of the legend hereunder. When the Shares or Warrant Shares may be sold under Rule 144 without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares or Warrant Shares and without volume or manner-of-sale restrictions, then such Warrant Shares shall be issued free of all legends. The Company agrees that following the Effective Date of a Registration Statement with respect to the Shares and Warrant Shares registered on such Registration Statement, or at such time as such legend is no longer required under this Section 4.1(c), it will, no later than three (3) Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent of (A) a certificate representing the applicable portion of the Shares or Warrant Shares, as the case may be, issued with a restrictive legend and (B) to the extent the Purchaser is an Affiliate of the Company (it being agreed and acknowledged that the Purchaser shall not be deemed to be an Affiliate of the Company at any time that the Purchaser Condition is satisfied) any documentation reasonably requested by the Company demonstrating such Purchaser’s compliance with all of the applicable requirements of Rule 144 (such third (3rd) Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. If the Company shall fail for any reason or for no reason to issue to such Purchaser of the Securities on or before the Legend Removal Date a certificate without such legend or to issue such Securities to such Purchaser by electronic delivery at the applicable balance account at DTC, and if on or after such Trading Day the Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Purchaser of such Securities that the Purchaser anticipated receiving without legend from the Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Purchaser’s request and in the Purchaser’s discretion, either (i) pay cash to the Purchaser in an amount equal to the Purchaser’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such unlegended Securities shall terminate, or (ii) promptly honor its obligation to deliver to the Purchaser such unlegended Securities or to issue such Securities to such Purchaser by electronic delivery at the applicable balance account at DTC as provided above and pay cash to the Purchaser in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Weighted Average Price (as defined in the Warrants) of the Common Stock on the Legend Removal Date. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Certificates for Securities subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by (X) upon the request of the Purchaser, crediting the Purchaser’s or its designee’s balance account with the DTC through DWAC, or to the Purchaser’s or its designee’s direct registration account, provided that the Transfer Agent is participating in the DRS or FAST Program, or (Y) if the Transfer Agent is not participating in either the DRS or FAST Program, issuing and dispatching by overnight courier to the address as specified in the notice section hereof, a certificate registered in the Company’s share register in the name of the Purchaser.

(d) Each Purchaser, severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if Securities are sold pursuant to a registration statement (including the Registration Statement), they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding.

4.2 Continued Registration; Public Information. Until such time that the Purchaser owns no Securities, the Company covenants to use reasonable best efforts to maintain the registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and 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 even if the Company is not then subject to the reporting requirements of the Exchange Act, and if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities, including without limitation, under Rule 144.

4.3 Integration. The Company shall not 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 or that would be integrated with the offer or sale of the Securities such that it would require stockholder approval for purposes of the rules and regulations of any Trading Market or otherwise unless stockholder approval is obtained before the closing of such subsequent transaction.

4.4 Warrants. The Company hereby covenants and agrees to comply with each and every one of its obligations and other terms set forth in the Warrants, including, without limitation, Section 3(d) of the Warrants and Section 5 of the Series C 2014 Warrants, for so long as any such Warrants remain outstanding.

4.5 Shareholder Rights Plan and Anti-Takeover Plans. Assuming that the Purchaser does not beneficially own any Common Stock or Common Stock Equivalents not purchased from the Company immediately prior to the execution of this Agreement, at no time following the Company’s issuance of the Shares, Warrants or Warrant Shares (assuming the exercise in full of the Warrants without regard to any limitations on exercise of the Warrants) will any claim be raised or enforced by the Company or, with the consent of or without the opposition of the Company, any other Person, that (i) any Purchaser is an “Acquiring Person” or functionally equivalent Person under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement), or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company or other similar anti-takeover provision under the Company’s certificate of incorporation or the laws of its state of incorporation, (ii) any Purchaser could be deemed to trigger the provisions of any such plan or arrangement or other anti-takeover provision, in whole or in part, by virtue of receiving Shares or Warrants under this Agreement or Warrant Shares upon exercise of any such Warrants or under any other agreement between the Company and the Purchasers, assuming that the facts and circumstances that exist as of the Closing Date are not materially changed by a Purchaser (it being agreed and acknowledged by the Company that neither an exercise of any or all of the Warrants (assuming the exercise in full of the Warrants without regard to any limitations on exercise of the Warrants) nor any waiver of Section 2(d) of the Warrants in accordance with the terms thereof shall be deemed to be a material change in the facts and circumstances that exist as of the Closing Date), or (iii) any Purchaser is an “Interested Stockholder” or an “Affiliate” or “Associate” of an “Interested Stockholder” (as such terms are defined in Section 203 of the Delaware General Corporation Law). For the avoidance of doubt, no Purchaser’s ownership of any or all of the Securities or the 2012 Securities shall be taken into account when calculating such Purchaser’s percentage ownership in the Company and shall not count towards any ownership threshold for purposes of any control share acquisition, business combination, poison pill (including any distribution under a rights agreement), or other similar anti-takeover provision under the Company’s certificate of incorporation or bylaws or the laws of its state of incorporation (including Section 203 of the Delaware General Corporation Law).

4.6 Securities Laws Disclosure; Publicity. The Company shall (a) by 5:30 p.m. (New York City time) on December 24, 2014, issue a press release disclosing all material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. From and after the issuance of such press release, the Company shall have publicly disclosed all material, non-public information delivered to any of the Purchasers (or any of their respective Affiliates or any of their or their Affiliates’ respective officers, directors, employees, advisors, representatives or agents) by the Company, the Subsidiary or any of their respective Affiliates or any of their officers, directors, employees, shareholders, advisors, representatives or agents (collectively, the “Company Group”). The Company acknowledges and agrees that the Purchasers (and their respective Affiliates) do not owe the Company Group or any other Person any duty of confidentiality, duty to not use or duty to not trade (or any similar duty or obligation) with respect to any information of, about, regarding, or related to the Company and that the Purchasers shall be unrestricted from trading the Common Stock of the Company. Except as required to be disclosed in any SEC Reports pursuant to applicable law and regulation (provided that the Purchasers shall be consulted by the Company in connection with any such disclosure prior to its release or use), without the prior written consent of any applicable Buyer, neither the Company nor any of its Subsidiaries or affiliates shall disclose the name of such Buyer in any filing, announcement, release or otherwise.

4.7 Non-Public Information. From and after the filing of the press release contemplated by Section 4.6, the Company covenants and agrees that neither it, the Subsidiary, nor any other Person acting on its or their behalf, will provide any Purchaser or its agents or counsel with any material non-public information, unless prior thereto such Purchaser shall have entered into a written agreement with the Company regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in the securities of the Company. If a Purchaser has, or believes it has, received any material, nonpublic information regarding the Company or the Subsidiary from the Company, the Subsidiary or any of their respective officers, directors, Affiliates or agents, it may provide the Company with written notice thereof. The Company shall, within two (2) Trading Days of receipt of such notice, make public disclosure of such material, nonpublic information. To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent, the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality with respect to, or a duty not to trade on the basis of or otherwise not to use, such material, non-public information. The Company understands and confirms that the Purchasers are in the business of trading public securities such as the Common Stock of the Company and will rely on the provisions of Sections 4.6 and 4.7 and the other representation, warranties and provisions in this Agreement and the other Transaction Documents in effecting transactions in Common Stock of the Company.

4.8 Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder primarily for the ongoing development of bremelanotide for treatment of female sexual dysfunction, preclinical and clinical development of its melanocortin receptor-1 peptide program, preclinical and clinical development of its PL-3994 product and preclinical and clinical development of other portfolio products, and for working capital and general corporate purposes.

4.9 Indemnification of Purchasers. Subject to the provisions of this Section 4.9, the Company will indemnify and hold each Purchaser and its Affiliates, investment manager, directors, officers, stockholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the Affiliates, directors, officers, stockholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all 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 that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of, failure to comply with or adhere to, misrepresentation with respect to or relating to, or any act or omission inconsistent with, any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents, including, without limitation, and for purposes of clarification, any claims any Purchaser Party may have against the Company for any such breach, failure misrepresentation, act or omission pursuant to any provision of any Transaction Document, including, without limitation, Sections 4.4, 4.5 and 4.17 through 4.24 of this Agreement, or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser Parties, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such Purchaser Parties of state or federal securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or willful malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable written opinion of counsel to the Purchasers furnished to the Company, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent, that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such Purchaser Parties of state or federal securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or willful malfeasance. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 4.9 shall be the same as those set forth in Section 5 of the Registration Rights Agreement.

4.10 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants. The Company shall reserve and so long as any Securities are outstanding, the Company shall continue to reserve and keep available at all times, free of preemptive rights, a number of shares of Common Stock equal to the maximum number of Shares issuable pursuant to this Agreement and Warrant Shares issuable pursuant to any exercise of the Warrants (without regard to any restrictions on exercise thereof) (the “Required Reserve Amount”).

4.11 Listing of Common Stock. The Company hereby agrees to use commercially reasonable efforts to maintain the listing or quotation of the Common Stock on the Trading Market on which it is currently listed, and the Company shall apply to list or quote the Shares and Warrant Shares on such Trading Market and use commercially reasonable efforts to secure the listing of the Shares and Warrant Shares on such Trading Market in the time and manner required thereby. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will then include in such application the Shares and Warrant Shares, and will take such other action as is necessary to cause the Shares and Warrant Shares to be listed or quoted on such other Trading Market in the time and manner required thereby. The Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market.

4.12 Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid to any Purchaser (or any Affiliate of a Purchaser) to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of securities or otherwise.

4.13 Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.6. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described in Section 4.6, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents. Notwithstanding the foregoing, any Purchaser may disclose the existence and terms of this transaction and the information included in the Transaction Documents if it reasonably believes it is required to make such disclosure in order to comply with applicable law, regulation or rule (including, without limitation, any rule, regulation or policy statement of (i) any organized securities exchange, market or automated quotation system on which the Company’s securities are listed or quoted, (ii) any self-regulatory organization of which a party is a member, or (iii) any legal or judicial process) or as part of any audit or regulatory examination. Notwithstanding the foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser nor any other Attribution Party makes any representation, warranty or covenant hereby that it or any other Attribution Party will not engage in effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.6, (ii) no Purchaser nor any other Attribution Party shall be restricted or prohibited from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.6, and (iii) no Purchaser nor any other Attribution Party shall have any duty of confidentiality to the Company after the issuance of the initial press release as described in Section 4.6. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.

4.14 Blue Sky Filings; Violation of Law. (i) The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser. (ii) Neither the Company, nor any of its Subsidiaries, nor any director, officer, agent, employee or other Person acting on behalf of the Company or any of its Subsidiaries will undertake any action that would be reasonably likely to constitute a breach of the representations and warranties provided in Sections 3.1(l) or 3.1(bb) hereof if such action had been taken on or prior to the Closing Date.

4.15 Acknowledgment of Dilution. The Company and each of the Purchasers acknowledges that the issuance of the Securities may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the Shares and Warrant Shares pursuant to the Transaction Documents, are not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

4.16 Public Information. At any time during the period commencing on the six (6) month anniversary of the Closing Date and ending at such time that all of the Securities, if a registration statement is not available for the resale of all of the Securities, may be sold without restriction or limitation pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1), if the Company shall (i) fail to use its best efforts to satisfy the requirements of Rule 144(c)(1), including, without limitation, the failure to satisfy the current public information requirement under Rule 144(c) or (ii) if the Company has ever been an issuer described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Company shall fail to use its best efforts to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”) then, as partial relief for the damages to any Purchaser or other holder of Securities by reason of any such delay in or reduction of its ability to sell the Securities (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each such Purchaser and holder an amount in cash equal to one percent (1.0%) of the aggregate Subscription Amount of such Purchaser or holder’s Securities on the day of a Public Information Failure and on every thirtieth (30th) day (pro rated for periods totaling less than thirty (30) days) thereafter until the earlier of (i) the date such Public Information Failure is cured and (ii) such time that such public information is no longer required pursuant to Rule 144. The payments to which a Purchaser and other holders shall be entitled pursuant to this Section 4.16 are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Public Information Failure Payments are incurred and (II) the third Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. The Company shall be liable for all payments to each Purchaser pursuant to this Section 4.16 and such payments shall be a liability and debt obligation of the Company, and each Purchaser shall be a creditor of the Company with respect to such obligation, that is immediately due and payable pursuant to and in accordance with this Section 4.16.

4.17 Additional Issuances of Securities. Prior to the one (1) year anniversary of the Closing Date the Company shall not issue any securities pursuant to any Post-Closing Registration Statement. So long as the Initial Purchasers beneficially own in the aggregate Common Stock or Common Stock Equivalents equal to or convertible or exercisable, as the case may be, into at least 5% of the Company’s outstanding shares of Common Stock (calculated as if the Warrants and the 2012 Warrants were exercised in full without regard to any limitations on exercise of the Warrants or the 2012 Warrants), the Company shall not without the written consent of the Initial Purchasers, and the Company shall not permit its Subsidiary to, directly or indirectly, (i) issue a number of shares of Common Stock (including shares underlying any Common Stock Equivalents) in excess of (I) during calendar year 2015, fifteen percent (15%) (as adjusted for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement) of the aggregate number of shares of Common Stock and Common Stock Equivalents outstanding after the Closing, and (II) in any calendar year thereafter, ten percent 10% (as adjusted for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement) of the aggregate number of shares of Common Stock and Common Stock Equivalents outstanding after Closing; provided that this clause (i) (subject to the first sentence of this Section 4.17) shall not apply to Excluded Securities, or (ii) authorize or grant, or otherwise increase or modify any authorization or grant or existing right under, any option to purchase any of the Company’s or its Subsidiaries’ equity or equity equivalent securities, including restricted stock units and options to purchase Common Stock pursuant to the Company’s 2011 Stock Incentive Plan or any other Approved Stock Plan; provided that the Company may take the foregoing actions in this clause (ii) in an amount that does not exceed in the aggregate the number of shares of Common Stock and Common Stock Equivalents permissibly issuable pursuant to an Approved Stock Plan.

4.18 Right of Participation. (a) From and after the Closing Date until the Right of Participation End Date, the Company shall not, and the Company shall not permit its Subsidiary to, directly or indirectly, effect any Subsequent Equity Placement unless the Company shall have first complied with this Section 4.18.

(i) Prior to entering into any Subsequent Equity Placement with any Person other than the Purchasers, the Company shall deliver to each Purchaser an irrevocable written notice (the “Offer Notice”) of any proposed or intended issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Placement”) in a Subsequent Equity Placement, which Offer Notice shall (w) offer to issue and sell to or exchange with such Purchasers their respective Requisite Percentages of the Offered Placement (the “Purchaser Amount”), in each instance allocated among such Purchasers as indicated by the Purchasers, (x) identify and describe the Offered Placement, (y) describe whether the Offered Placement is at the market or provide a range (such range not to exceed fifteen percent (15%) above or below market) of the anticipated discount to market, including warrant coverage, and describe other material terms upon which they are to be issued, sold or exchanged (to the extent known), and the approximate number or amount of the securities or Indebtedness expected to comprise the Offered Placement to be issued, sold or exchanged and (z) identify the persons or entities (if known) to which or with which the securities or Indebtedness comprising the Offered Placement are to be offered, issued, sold or exchanged (the “Basic Amount”).

(ii) To accept an Offer, whether of the entirety of the Purchaser Amount or a portion thereof, such Purchaser must deliver a written notice to the Company prior to the end of the fifth (5th) Business Day after such Purchaser’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of such Purchaser’s Purchaser Amount, which may be all or any portion of such Purchaser’s Purchaser Amount, that such Purchaser elects to purchase (the “Notice of Acceptance”). Notwithstanding anything to the contrary contained herein, if the Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to the Purchasers a new Offer Notice and the Offer Period shall expire on the fifth (5th) Business Day after such Purchaser’s receipt of such new Offer Notice.

(iii) The Company shall have ten (10) Business Days from the expiration of the Offer Period above to consummate the Subsequent Equity Placement with respect to all or any part of such Offered Placement as to which a Notice of Acceptance has not been given by the Purchasers (the “Refused Placement”) pursuant to a definitive agreement (the “Subsequent Placement Agreement”) but only upon terms and conditions (including, without limitation, unit prices and interest rates (or within such range)) that are not more favorable to the acquiring Person or Persons or less favorable to the Company than those set forth in the Offer Notice.

(iv) In the event the Company shall propose to sell less than 80% of all the securities or Indebtedness comprising the Refused Placement (any such sale to be in the manner and on the terms specified in Section 4.18(a)(iv) above), then prior to the end of the fifth (5th) Business Day after such Purchaser’s receipt of written notice of the Company’s proposal to sell such reduced amount of securities or Indebtedness comprising the Refused Placement, each Purchaser may, at its sole option and in its sole discretion, reduce the number or amount of the securities or Indebtedness comprising the Offered Placement specified in its Notice of Acceptance or revoke its Notice of Acceptance. In the event the Company shall propose to sell less than 100% but 80% or more of all the securities or Indebtedness comprising the Refused Placement (any such sale to be in the manner and on the terms specified in Section 4.18(a)(iv) above), then prior to the end of the fifth (5th) Business Day after such Purchaser’s receipt of written notice of the Company’s proposal to sell such reduced amount of securities or Indebtedness comprising the Refused Placement, each Purchaser may, at its sole option and in its sole discretion, proportionally reduce the number or amount of the securities or Indebtedness comprising the Offered Placement specified in its Notice of Acceptance. In the event that any Purchaser so elects to reduce the number or amount of securities or Indebtedness comprising the Offered Placement specified in its Notice of Acceptance or revoke its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Placement unless and until such securities have again been offered to the Purchasers in accordance with Section 4.18(a)(ii) above.

(v) Any securities or Indebtedness comprising the Offered Placement not acquired by the Purchasers or other Persons in accordance with Section 4.18(a)(iv) above may not be issued, sold or exchanged until they are again offered to the Purchasers under the procedures specified in this Agreement.

(vi) The purchase by the Purchasers of any securities comprising the Offered Placement is subject in all cases to the preparation, execution and delivery by the Company and the Purchasers of a purchase agreement relating to such Offered Placement reasonably satisfactory in form and substance to the Purchasers and their respective counsel. The Company and the Purchasers agree that if any Purchaser elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or provisions whereby any Purchaser shall be required to agree to any restrictions in trading as to any securities of the Company owned by such Purchaser prior to such Subsequent Equity Placement.

(vii) Notwithstanding anything to the contrary in this Section 4.18 and unless otherwise agreed to by the Purchasers, the Company shall either confirm in writing to the Purchasers that the transaction with respect to the proposed Subsequent Equity Placement has been abandoned or shall publicly disclose its intention to consummate the transactions contemplated by the proposed Subsequent Equity Placement, in either case in a manner such that the Purchasers will not be in possession of material non-public information, by the twentieth (20th) Business Day following delivery of any Offer Notice. If by the twentieth (20th) Business Day following delivery of any Offer Notice no public disclosure regarding a transaction with respect to the proposed Subsequent Equity Placement has been made, and no notice regarding the abandonment of such transaction has been received by the Purchasers, such transaction shall be deemed to have been abandoned and the Purchasers shall not be deemed to be in possession of any material, non-public information with respect to the Company. Should the Company decide to pursue such transaction with respect to the proposed Subsequent Equity Placement, the Company shall provide each Purchaser with another Offer Notice and each Purchaser will again have the right of participation set forth in this Section 4.18(a). The Company shall not be permitted to deliver more than one Offer Notice to the Purchasers in any forty (40) Business Day period.

(b) The restrictions contained in this Section 4.18 shall not apply in connection with the issuance of any Excluded Securities. Notwithstanding anything to the contrary contained herein, all rights of any Purchaser set forth in this Section 4.18 shall be assignable at the election of any Purchaser to one or more of any Purchaser’s Affiliates, but not otherwise. For purposes of clarification, the provisions of this Section 4.18 are to apply to any Subsequent Equity Placement, including multiple Subsequent Equity Placements, whether related or unrelated, during the period covered hereby.

(c) If and to the extent that any Purchaser, including Affiliates and Attribution Parties of the Purchaser, has a right to participate in any offering of securities of the Company under any other agreement, including without limitation a right to participate arising under Section 4.18 of the 2012 Offering SPA (the "Prior Rights"), none of the rights hereunder shall modify, limit or supersede such Prior Rights; provided, however, that the securities that such Purchaser may purchase hereunder and pursuant to the Prior Rights shall not be aggregated.

4.19 Fundamental Transactions. The Company covenants and agrees while any Warrants are outstanding, it (i) will not permit (to the extent within its control), (ii) will take all necessary action to prevent both the occurrence or consummation of (including, without limitation, adopting a poison pill or other similar anti-takeover provision or method) and the requirement to make any payment or adjustment or issue any shares of Common Stock or other securities with respect to, and (iii) will not be party to, any fundamental transaction, change of control or similar event, or an event that with the passage of time could result in a fundamental transaction, change of control or similar event under any agreement (including, without limitation, any employment agreement), outstanding security (including, without limitation, any option or warrant to purchase Common Stock) or other instrument or make any announcement of any of the foregoing. In furtherance of the foregoing and without limiting in any manner any other rights of the Purchasers or obligations of the Company set forth in any of the Transaction Documents, in the event the Company learns of any third party attempting or seeking to take action to cause a fundamental transaction, change of control or similar event (including, without limitation, through a tender or exchange offer), or an event that with the passage of time could result in a fundamental transaction, change of control or similar event (including, without limitation, through a tender or exchange offer) under any agreement (including, without limitation, any employment agreement), outstanding security (including, without limitation, any option or warrant to purchase Common Stock) or other instrument, that does not conform to the requirements of the Transaction Documents and that does not afford or grant the Purchasers all of the rights and payments they would receive in a Company Controlled Fundamental Transaction (including, without limitation, any payments they would receive if they were holders of the shares of Common Stock issuable upon exercise of the Warrants (without regard to any limitation on the exercise of the Warrants)), subject to the exercise by the Board of Directors of the Company of its fiduciary duties in accordance with applicable law, the Company covenants and agrees to take all reasonable efforts to adopt a poison pill, and to the extent that any previously adopted poison pill ceases to be effective, to re-adopt a poison pill, or any other anti-takeover provision or method necessary to prevent such fundamental transaction, change of control or similar event (including, without limitation, through a tender or exchange offer), or event that with the passage of time could result in a fundamental transaction, change of control or similar event (including, without limitation, through a tender or exchange offer) under any agreement or other instrument, that does not conform to the requirements of the Transaction Documents and that does not afford or grant the Purchasers all of the rights and payments they would receive in a Company Controlled Fundamental Transaction (including, without limitation, any payments they would receive if they were holders of the shares of Common Stock issuable upon exercise of the Warrants (without regard to any limitation on the exercise of the Warrants)). The Company covenants and agrees while any Warrants are outstanding, that it will not permit, will take all necessary action to prevent (including, without limitation, adopting a poison pill or other similar anti-takeover provision), and will not be party to, any Fundamental Transaction unless the Company and each applicable acquirer or beneficial owner of securities that is directly or indirectly party to or associated with any applicable Fundamental Transaction, including each Successor Entity or Successor Entities, jointly and severally agrees (x) to the requirements and other provisions set forth in the Warrants, including, without limitation, Section 3(d) thereto and all requirements to issue cash, securities (including, without limitation any options or warrants to purchase Common Stock) or other assets thereunder, and (y) to treat each holder of the Warrants (each, a “Holder”) in all respects no worse than as if such Holder was a holder of Warrant Shares and no worse (and, other than in

connection with a Company Controlled Fundamental Transaction (as defined in the Warrants), no better) than its treatment of any other holder of shares of Common Stock. For purposes of clarification, the foregoing shall mean that no Fundamental Transaction shall occur or be consummated unless (i) to the extent set forth in the Warrants, each Holder shall have the right to require the Company and/or the Successor Entity and/or Successor Entities, jointly and severally, to deliver upon the occurrence or consummation, and it shall be a required condition to such occurrence or consummation, of the Fundamental Transaction or at any time thereafter, in satisfaction of the Warrants, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights and any shares of Common Stock) which each Holder would have been entitled to receive upon the happening of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental Transaction, had the Warrants been exercised in full (without regard to any limitations on exercise of the Warrants) with such Holder becoming a holder of such shares of Common Stock issuable upon such exercise immediately prior to such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental Transaction; (ii) it is recognized that the purpose of this Section 4.19 is to assure that in all circumstances of any Fundamental Transaction or similar corporate type transaction, each Holder will have rights pursuant to the terms of the Warrants no worse (and, other than in connection with a Company Controlled Fundamental Transaction, no better) in any way than or adversely affected relative to or in any manner not as advantageous (or, other than in connection with a Company Controlled Fundamental Transaction, disadvantageous) as those of a holder of the number of shares of Common Stock issuable upon exercise of the Warrants (without regard to any limitations on exercise of the Warrants) as if the Warrants had already been exercised into Common Stock (without regard to any limitations on exercise of the Warrants) prior to such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental Transaction and shall not receive worse (or, other than in connection with a Company Controlled Fundamental Transaction pursuant to the terms of the Warrants, better) treatment, be prejudiced or adversely affected relative to (or treated in any manner not as advantageous or, other than in connection with a Company Controlled Fundamental Transaction, disadvantageous) as the treatment afforded to any holders of shares of Common Stock in such Fundamental Transaction or similar corporate type transaction by virtue of the fact that a Holder holds a Warrant rather than the shares of Common Stock issuable upon exercise of the Warrant (without regard to any limitations on exercise of the Warrant); (iii) it is specifically intended that no Person attempt to structure a transaction in any manner to circumvent the intent of this Section 4.19 and therefore the provisions of this Section 4.19 shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4.19 and pursuant to the terms of the Warrants to the extent necessary to correct this paragraph or any portion hereof which may be defective or inconsistent with the intended treatment of each Holder, or to make changes or supplements necessary or desirable to properly give effect to such treatment, as no worse (or, other than in connection with a Company Controlled Fundamental Transaction, no better) in any way than or adversely effected relative to or in any manner not as advantageous (or, other than in connection with a Company Controlled Fundamental Transaction, disadvantageous) as a holder of the number of shares of Common Stock issuable upon exercise of the Warrants (without regard to any limitations on exercise of the Warrants) in any Fundamental Transaction or similar corporate type transaction as herein contained; (iv) it is specifically intended, among other events and transactions, that any tender offer or similar transaction made with respect to the Company or 50% or more of the Common Stock is deemed a Fundamental Transaction under the Warrants; (v) it is acknowledged that notwithstanding any provision that may be interpreted to the contrary, as provided in the Warrants each Holder has an express right to receive at least the same proportion and amount of cash, if any, per Warrant Share (provided, that the foregoing shall in no way limit the rights of the Holder to get any Fundamental Transaction Warrant Early Termination Price (as defined in the Warrants) entirely in cash) that each holder of a share of Common Stock is entitled to receive from the Company or any Successor Entity or Successor Entities, upon any Fundamental Transaction (such as a cash merger or cash tender offer) where cash comprises any portion of the applicable consideration or payment, that they would have been entitled to receive had they exercised their Warrants prior to the Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental Transaction (without regard to any limitations on the exercise of this Warrant); (vi) it is acknowledged that the provisions of this Section 4.19 may not be waived, modified or otherwise implemented otherwise than in strict conformity with the intention hereof and shall apply to a successor holder of the Warrants and any Successor Entity or Successor Entities, and (vii) notwithstanding any provision of this Agreement, the Warrants or any other agreement or contract that could in any way be read to limit the right of any Holder to elect and receive at any time in perpetuity any payments pursuant to the Warrants, no provision of this Agreement, the Warrants or any other agreement or contract shall limit the rights of any Holder (including, without limitation, the right to receive any Redemption Price (as defined in the Warrants)) to receive at any time in perpetuity any payments pursuant to the Warrants. The Purchasers shall be third party beneficiaries to any agreements between the Company and any applicable Successor Entity in order to give effect to this Section 4.19.

4.20 Subdivisions. So long as any Warrants are outstanding, the Company shall not subdivide (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares or take any other action or otherwise allow the Exercise Price (as defined in the Warrants) of the Warrants to be less than the par value of the Common Stock.

4.21 Contrary Positions. The Company covenants and agrees not to take any position contrary to (x) the representations set forth in Section 3.1(hh) and Section 3.1(jj), as if each such representation was made on any date from and after the Closing Date assuming (i) the facts and circumstances that exist as of the Closing Date are not materially changed by a Purchaser and (ii) with respect to the representation in clause (ii) of the first sentence of Section 3.1(jj), the Purchaser Condition is satisfied or (y) any of its other representations set forth herein, as if each such representation was made on the Closing Date, assuming the facts and circumstances that exist as of the Closing Date with respect to such representations are not materially changed. The Company acknowledges and agrees that, with respect to Section 3.1(hh) neither an exercise of any or all of the Warrants or the 2012 Warrants (assuming the exercise in full of the Warrants and the 2012 Warrants without regard to any limitations on exercise of the Warrants or the 2012 Warrants) nor any waiver of Section 2(d) of the Warrants in accordance with the terms thereof shall be deemed to be a material change in the facts and circumstances that exist as of the Closing Date.

4.22 No Stock Buy-Backs, Dividends or Purchase Rights. So long as any Purchaser holds any of the Securities, the Company shall not redeem, repurchase or otherwise reduce the number of outstanding shares of Common Stock (except for stock repurchases in the ordinary course of business in connection with tax withholding obligations upon vesting of restricted stock or restricted stock units issued under an Approved Stock Plan in the amount not to exceed fifty percent (50%) of the vested amount of the restricted stock and restricted stock units). So long as the Purchasers in the aggregate beneficially own Common Stock or Common Stock Equivalents equal to or convertible or exercisable, as the case may be, into at least 20% of the Company’s outstanding shares of Common Stock (calculated as if the Warrants and the 2012 Warrants were exercised in full without regard to any limitations on exercise of the Warrants or the 2012 Warrants), the Company shall not, and the Company shall not permit its Subsidiary to, directly or indirectly, (x) declare or make any dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of its Common Stock, capital stock or Common Stock Equivalents, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) or (y) grant, issue or sell any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of its capital stock or Common Stock Equivalents.

4.23 Existence of Liens. So long as the Purchasers in the aggregate beneficially own Common Stock or Common Stock Equivalents equal to or convertible or exercisable, as the case may be, into at least 20% of the Company’s outstanding shares of Common Stock (calculated as if the Warrants and the 2012 Warrants were exercised in full without regard to any limitations on exercise of the Warrants or the 2012 Warrants), the Company shall not, and the Company shall not permit its Subsidiary to, directly or indirectly, allow or suffer to exist any Lien other than Permitted Liens.

4.24 Amendments and Future Agreements. So long as any Purchaser holds any of the Warrants, the Company shall not (i) amend, waive, modify or terminate any provision of any outstanding securities (including, without limitation, any warrants) or (ii) be party to any transaction (including any contract, agreement or other arrangement) or issue any security (including, without limitation, any option or warrant to purchase Common Stock) or other instrument, with a provision or term (including, without limitation, any fundamental transaction, change of control or similar event provision) which in any way (I) restricts the Company’s ability to issue any shares of Common Stock or other securities as a result of, the Company’s issuance of, any of the Securities, Warrants, 2012 Securities or 2012 Warrants or (II) restricts the Company’s ability to make any payment in full or any adjustment under any of the Securities, Warrants, 2012 Securities or 2012 Warrants or (III) is triggered by, or could require the Company to make any payment or adjustment or issue any shares of Common Stock or other securities as a result of, the Company’s issuance of, any of the Securities, Warrants, 2012 Securities or 2012 Warrants.

4.25 2012 Offering. Notwithstanding any provision of this Agreement or any Transaction Document that could or may be construed to the contrary, nothing in this Agreement or any Transaction Document shall in any manner whatsoever (i) modify, limit, or supersede any provision of any agreement entered into or any right of the purchasers in the 2012 Offering or obligation of the Company relating to or arising from the 2012 Offering or (ii) require or allow for any payment or issuance to be made in connection with the offering contemplated hereby (including the Warrants) unless a payment or issuance obligation is triggered and made in connection with the 2012 Offering Documentation (including the 2012 Warrants) such that if any event triggers a payment under a Transaction Document (including the Warrants), such event shall also be deemed to trigger a payment under the 2012 Offering Documentation (including the 2012 Warrants).

Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or 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 other manner permitted by law.

5.10 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 each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, 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 or “.pdf” signature page were an original thereof.

5.11 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

5.12 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 (in the case of mutilation), 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, if requested by the Company, the posting of a customary bond. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

5.13 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. The Company therefore agrees that the Holders shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security. In the event that the Purchaser delivers a Fundamental Transaction Early Termination Notice (as defined in the Warrants) pursuant to a Clause C Fundamental Transaction (as defined in the Warrants) and the Company pays in full to the Purchaser, pursuant to and in accordance with the terms of Section 3(d) of the Warrants, the related Fundamental Transaction Warrant Early Termination Price (as defined in the Warrants), the Purchaser shall not be entitled to any other payment for damages hereunder with respect to such redeemed Warrants solely in connection with such Clause C Fundamental Transaction.

5.14 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers, and the Company acknowledges that the Purchasers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations, the transactions contemplated by the Transaction Documents, the Company or its Common Stock. Each Purchaser shall be entitled, at its own expense, 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 Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents.

5.15 Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

5.16 Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement.

WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
