(z) Investment Company Act Status. The Company is not, and as a result of and immediately upon the Closing will not be, an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

(aa) Independent Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents. The Company acknowledges that the decision of each Purchaser to purchase Notes and Debt Warrants pursuant to this Agreement has been made by such Purchaser independently of any other purchase and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges that for reasons of administrative convenience only, the Transaction Documents have been prepared by counsel for one of the Purchasers and such counsel does not represent all of the Purchasers but only such Purchaser and the other Purchasers have retained their own individual counsel with respect to the transactions contemplated hereby. The Company acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby. The Company acknowledges that each Purchaser 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 Purchaser to be joined as an additional party in any proceeding for such purpose.

(bb) No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Notes and the Debt Warrants pursuant to this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Securities pursuant to Regulation D and Rule 506 thereof under the Securities Act nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings if to do so would prevent the Company from selling Securities pursuant to Regulation D and Rule 506 thereof under the Securities Act or otherwise prevent a completed offering of Securities hereunder. Except as set forth on Schedule 2.1(bb) hereto, the Company does not have any registration statement pending before the SEC or currently under the SEC’s review and since December 31, 2010, the Company has not offered or sold any of its equity securities or debt securities convertible into shares of Common Stock.

(cc) Dilutive Effect. The Company understands and acknowledges that its obligation to issue Conversion Shares upon conversion of the Notes in accordance with this Agreement and the Notes is absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interest of other stockholders of the Company.

(dd) DTC Status. Except as set forth on Schedule 2.1(dd) hereto, the Company’s transfer agent is a participant in and the Common Stock is eligible for transfer pursuant to the Depository Trust Company Automated Securities Transfer Program. The name, address, telephone number, fax number, contact person and email of the Company transfer agent is set forth on Schedule 2.1(dd) hereto.

(ee) Governmental Approvals. Except for the filing of any notice prior or subsequent to the Closing that may be required under applicable state and/or federal securities laws (which if required, shall be filed on a timely basis) and the declaration of the effectiveness of any registration statements filed by the Company pursuant to the Transaction Documents, no authorization, consent, approval, license, exemption of, filing or registration with any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, is or will be necessary for, or in connection with, the execution or delivery of the Conversion Shares, or for the performance by the Company of its obligations under the Transaction Documents.

(ff) Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(gg) Trading Activities. Except as set forth herein or in the Notes, it is understood and acknowledged by the Company that none of the Purchasers have been asked to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Securities for any specified term. The Company further understands and acknowledges that (a) one or more Purchasers may engage in hedging and/or trading activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Conversion Shares are being determined and (b) such hedging and/or trading activities, if any, can reduce the value of the existing stockholders’ equity interest in the Company both at and after the time the hedging and/or trading activities are being conducted. The Company acknowledges that such aforementioned hedging and/or trading activities, assuming such trading and hedging activities are in compliance with all applicable securities laws, do not constitute a breach of this Agreement, the Notes, the Debt Warrants or any of the documents executed in connection herewith.

2.2 Representations and Warranties of the Purchasers. Each of the Purchasers hereby represents and warrants to the Company with respect solely to itself and not with respect to any other Purchaser as follows as of the date hereof and as of the Closing Date:

(a) Organization and Standing of the Purchasers. If the Purchaser is an entity, such Purchaser is a corporation, limited liability company or partnership duly incorporated or organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization.

(b) Authorization and Power. Each Purchaser has the requisite power and authority to enter into and perform this Agreement, the Amendment Agreement and the Security Agreement and to purchase the Securities being sold to it hereunder. The execution, delivery and performance of this Agreement, the Amendment Agreement and the Security Agreement by each Purchaser and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate or partnership action, and no further consent or authorization of such Purchaser or its Board of Directors, stockholders, or partners, as the case may be, is required. When executed and delivered by the Purchasers, this Agreement, the Amendment Agreement and the Security Agreement shall constitute valid and binding obligations of each Purchaser enforceable against such Purchaser in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable principles of general application.

(c) Acquisition for Investment. Each Purchaser is purchasing the Securities solely for its own account and not with a view to or for sale in connection with distribution. Each Purchaser does not have a present intention to sell any of the Securities, nor a present arrangement (whether or not legally binding) or intention to effect any distribution of any of the Securities to or through any person or entity; provided, however, that by making the representations herein, such Purchaser does not agree to hold the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with federal and state securities laws applicable to such disposition. Each Purchaser acknowledges that it: (i) has such knowledge and experience in financial and business matters such that Purchaser is capable of evaluating the merits and risks of Purchaser’s investment in the Company; (ii) is able to bear the financial risks associated with an investment in the Securities; and (iii) has been given full access to such records of the Company and the Subsidiaries and to the officers of the Company and the Subsidiaries as it has deemed necessary or appropriate to conduct its due diligence investigation.

(d) Rule 144. Each Purchaser understands that the Securities must be held indefinitely unless such Securities are registered under the Securities Act or an exemption from registration is available. Each Purchaser acknowledges that such person is familiar with Rule 144 of the rules and regulations of the SEC, as amended, promulgated pursuant to the Securities Act (“Rule 144”), and that such Purchaser has been advised that Rule 144 permits resales only under certain circumstances. Each Purchaser understands that to the extent that Rule 144 is not available, such Purchaser will be unable to sell any Securities without either registration under the Securities Act or the existence of another exemption from such registration requirement.

(e) General. Each Purchaser understands that the Securities are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Securities. Each Purchaser understands that no United States federal or state agency or any government or governmental agency has passed upon or made any recommendation or endorsement of the Securities. Commencing on the date that the Purchasers were initially contacted regarding the investment in the Securities (pursuant to this Agreement), none of the Purchasers has engaged in any short sale of the Common Stock and will not engage in any short sale of the Common Stock prior to public announcement of the transactions contemplated by this Agreement pursuant to Section 3.10.

(f) No General Solicitation. Each Purchaser acknowledges that the Securities were not offered to such Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media, or broadcast over television or radio; or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications. Each Purchaser, in making the decision to purchase the Securities, has relied upon independent investigation made by it and has not relied on any information or representations made by third parties, and was not solicited through any pending registration statement of the Company described on Schedule 2.1(bb).

(g) Accredited Investor. Each Purchaser is an “accredited investor” (as defined in Rule 501 of Regulation D), and such Purchaser 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 Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act and such Purchaser is not a broker-dealer. Each Purchaser acknowledges that an investment in the Securities is speculative and involves a high degree of risk.

(h) Certain Fees. The Purchasers have not employed any broker or finder or incurred any liability for any brokerage or investment banking fees, commissions, finders’ structuring fees, financial advisory fees or other similar fees in connection with the Transaction Documents.

(i) Independent Investment. No Purchaser has agreed to act with any other Purchaser for the purpose of acquiring, holding, voting or disposing of the Securities purchased hereunder for purposes of Section 13(d) under the Exchange Act, and each Purchaser is acting independently with respect to its investment in the Securities.

2.3 Outstanding Notes and Purchase Rights. Each Purchaser represents and warrants that as of the Effective Date, such Purchaser holds the Company securities in the principal amounts set forth on such Purchaser’s signature page hereto.

ARTICLE 3

COVENANTS

Unless otherwise specified in this Article, for so long as any Notes or Debt Warrants remain outstanding in whole or in part, the Company covenants with each Purchaser as follows, which covenants are for the benefit of each Purchaser and their respective permitted assignees.

3.1 Securities Compliance. The Company shall notify the SEC in accordance with its rules and regulations, of the transactions contemplated by any of the Transaction Documents and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Securities to the Purchasers, or their respective subsequent holders.

3.2 Registration and Listing. The Company shall cause its Common Stock to continue to be registered under Sections 12(b) or 12(g) of the Exchange Act, to comply in all respects with its reporting and filing obligations under the Exchange Act and to not take any action or file any document (whether or not permitted by the Securities Act or the rules promulgated thereunder) to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act or Securities Act. The Company will take all action necessary to continue the listing or trading of its Common Stock on the OTC Bulletin Board (the “Principal Market”). The Company further covenants that it will take such further action as the Purchasers may reasonably request from time to time to enable the Purchasers to sell the Securities without registration under the Securities Act pursuant to the exemption provided by Rule 144 promulgated under the Securities Act. Upon the request of the Purchasers, the Company shall deliver to the Purchasers a written certification of a duly authorized officer as to whether it has complied with such requirements.

3.3 Inspection Rights. Provided the same would not be in violation of Regulation FD, the Company shall permit, during normal business hours and upon reasonable request and reasonable notice, each Purchaser or any employees, agents or representatives thereof, so long as such Purchaser shall be obligated hereunder to purchase the Notes or shall beneficially own any Conversion Shares, for purposes reasonably related to such Purchaser’s interests as a stockholder, to examine the publicly available, non-confidential records and books of account of, and visit and inspect the properties, assets, operations and business of the Company and any Subsidiary, and to discuss the publicly available, non-confidential affairs, finances and accounts of the Company and any Subsidiary with any of its officers, consultants, directors, and key employees.

3.4 Compliance with Laws. The Company shall comply, and cause each Subsidiary to comply, with all applicable laws, rules, regulations and orders, noncompliance with which would be reasonably likely to have a Material Adverse Effect.

3.5 Keeping of Records and Books of Account. The Company shall keep and cause each Subsidiary to keep adequate records and books of account, in which complete entries will be made in accordance with GAAP consistently applied, reflecting all financial transactions of the Company and its Subsidiaries, and in which, for each fiscal year, all proper reserves for depreciation, depletion, obsolescence, amortization, taxes, bad debts and other purposes in connection with its business shall be made.

3.6 Reporting Requirements. If the Company ceases to file its periodic reports with the SEC, or if the SEC ceases making these periodic reports available via the Internet without charge, then the Company shall furnish the following to each Purchaser so long as such Purchaser shall be obligated hereunder to purchase the Securities or shall beneficially own Securities:

(a) Quarterly Reports on Form 10-Q (or an equivalent form), including financial statements, promptly following the end of each quarter, and in any event within 45 days of the end of each quarter, if such reports are no longer filed with the SEC or as soon as practical after the document is filed with the SEC, and in any event within five days after the document is filed with the SEC;

(b) Annual Reports on Form 10-K (or an equivalent form), including financial statements, promptly following the end of each year, and in any event within 90 days of the end of each year, if such reports are no longer filed with the SEC or as soon as practical after the document is filed with the SEC, and in any event within five days after the document is filed with the SEC; and

(c) Copies of all notices, information and proxy statements in connection with any meetings that are, in each case, provided to holders of shares of Common Stock, contemporaneously with the delivery of such notices or information to such holders of Common Stock.

3.8 Use of Proceeds. The proceeds from the sale of the Securities hereunder shall be used by the Company for general corporate purposes. In no event shall the proceeds be used to redeem any Common Stock or securities convertible, exercisable or exchangeable into Common Stock, other than the repayment of debt pursuant to its terms, or to settle any outstanding litigation in excess of $100,000 per occurrence.

3.9 Reporting Status. So long as a Purchaser beneficially owns any of the Securities, the Company shall timely file all reports required to be filed with the SEC pursuant to the Exchange Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination.

3.10 Disclosure of Transaction. The Company shall issue a press release describing the material terms of the transactions contemplated hereby (the “Press Release”) no later than 9:00 A.M. Eastern Time on the first Trading Day following the effective date of this Agreement. The Company shall also file with the SEC, concurrently with the Press Release, a Current Report on Form 8-K (the “Form 8-K”) describing the material terms of the transactions contemplated hereby, which Press Release and Form 8-K shall be subject to prior review and comment by the Purchasers. “Trading Day” means any day during which the principal exchange on which the Common Stock is traded shall be open for trading.

3.11 Disclosure of Material Information. The Company covenants and agrees that neither it nor any other person acting on its behalf has provided or will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. The Company understands and confirms that each Purchaser shall be relying on the foregoing representations in effecting transactions in securities of the Company. In the event of a breach of the foregoing covenant by the Company, or any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, the Company shall publicly disclose any material, non-public information in a Form 8-K within one business day of the date that it discloses such information to any Purchaser. In the event that the Company discloses any material, non-public information to a Purchaser and fails to publicly file a Form 8-K in accordance with the above, a Purchaser shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents. No Purchaser shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents, for any such disclosure.

3.12 Pledge of Securities. The Company acknowledges that the Securities may be pledged by a Purchaser in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The 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 the 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; provided that a Purchaser and its pledgee shall be required to comply with the provisions of Article 5 hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. At the Purchasers’ expense, the Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by a Purchaser.

3.13 Amendments to Charter Documents. The Company shall not, without the written consent of the Requisite Purchasers, amend or waive any provision of the Certificate or Bylaws of the Company in any way that would adversely affect exercise rights, voting rights, conversion rights, prepayment rights, redemption rights or other rights of the holder of the Securities.

3.14 Maintenance of Insurance. The Company shall maintain, and cause each of its Subsidiaries to maintain, insurance with responsible and reputable insurance companies or associations (including, without limitation, comprehensive general liability, hazard, rent and business interruption insurance) with respect to its properties (including all real properties leased or owned by it) and business, in such amounts and covering such risks as is required by any governmental authority having jurisdiction with respect thereto or as is carried generally in accordance with sound business practice by companies in similar businesses similarly situated.

3.17 Subsequent Financings.

(b) For purposes of this Agreement, a Subsequent Financing shall not include the issuance of any Securities under the terms of this Agreement or Transaction Documents (including in connection with any adjustments to the conversion price of any such Securities pursuant to their terms).

3.18 Lock-Up Agreement. If, during the Lockup Period (as defined below), the Company hires or appoints any new officer or director who is required to comply with the reporting obligations under Section 16 of the Exchange Act and who has not executed a Lock-Up Agreement (as defined below), the Company shall cause each such executive officer and director to execute and deliver to the Purchasers a Lock-Up Agreement in connection with the commencement of such officer’s or director’s services to the Company. “Lockup Period” shall mean the earlier of (a) the date that is six (6) months following the Closing and (b) the date the Company enters into a strategic alliance or partnership with an unaffiliated Major Pharma Entity whereby the Company receives an upfront cash payment of at least $15,000,000. “Major Pharma Entity” shall mean any pharmaceutical or biotechnology company (including, for purposes of this Section, its direct and indirect majority-owned subsidiaries or a group of companies acting in concert) (1) whose total market capitalization is at least $2 billion or (2) with more than $500 million in revenue related to sales of pharmaceutical products or services.

The consent of the Requisite Purchasers shall be required for both the timing of and ratio for such reverse stock split; provided that no such consent shall be required to allow the Company to effect a reverse stock split beginning on the date that is one day following the one year anniversary of the Closing Date.

INDEMNIFICATION

6.1 General Indemnity. The Company agrees to indemnify and hold harmless the Purchasers (and their respective directors, officers, affiliates, members, managers, employees, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the Purchasers as a result of any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein.

6.2 Indemnification Procedure. Any party entitled to indemnification under this Article 6 (an “indemnified party”) will give written notice to the indemnifying party of any matter giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article 6 except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnifying party a conflict of interest between it and the indemnified party exists with respect to such action, proceeding or claim (in which case the indemnifying party shall be responsible for the reasonable fees and expenses of one separate counsel for the indemnified parties), to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within 30 days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party’s costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent. Notwithstanding anything in this Article 6 to the contrary, the indemnifying party shall not, without the indemnified party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification obligations to defend the indemnified party required by this Article 6 shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party shall refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.

ARTICLE 7

MISCELLANEOUS

7.1 Purchasers’ Agent.

(a) Appointment. The Purchasers hereby appoint Tang Capital Partners, LP, as the “Agent” for the Purchasers under the Security Agreement and the Collateral Agreement and Agent agrees to act as Agent in accordance with the terms and conditions of this Agreement, the Security Agreement and the Collateral Agreement. Notwithstanding anything to the contrary herein, the Agent may be removed or replaced with the written consent of the Requisite Purchasers (as defined in the Security Agreement). “Collateral”, as used herein, shall mean all of the collateral over which the Purchasers are granted a security interest pursuant to Security Agreement and the Collateral Agreement, collectively.

(b) Powers and Duties of Agent, Indemnity by Purchasers.

(i) Until the full release of the security interest in the Collateral, the Purchasers hereby authorize Agent to take all actions, to make all decisions and to exercise all powers and remedies on their behalf under the provisions of the H Notes and G Notes, including without limitation all such actions, decisions and powers as are reasonably incidental thereto. The Agent may execute any of its duties hereunder by or through agents, designees or employees. The powers conferred on the Agent hereunder are solely to ratably protect the interests in the Collateral of the holders of the H Notes and G Notes and shall not impose any duty upon it to exercise any such powers, provided that the Agent shall take (or refrain from taking) any action upon the written direction of the holders of 66 2/3% of the then outstanding principal amount of the either of the H Notes or G Notes, and shall act on behalf of, and for the ratable benefit of, the holders of the H Notes and G Notes in good faith and in a manner that it reasonably believes treats all holders of H Notes and G Notes proportionally, with respect to each series of notes. Except for the safe custody of any Collateral in its possession or control and the accounting for moneys actually received by it, the Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Agent has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession or control if such Collateral is accorded treatment substantially equal to that which it accords its own property. The Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects with reasonable care.

(ii) Neither the Agent nor any of its affiliates, partners, directors, members, officers, agents, designees, employees, trustees, or advisors (collectively, “Indemnified Persons”) shall be liable or responsible to any Purchaser for any action taken or omitted to be taken in good faith by Agent or any other such Indemnified Persons hereunder or under any related agreement, instrument or document (unless any such action taken or omitted to be taken shall be caused by the willful misconduct or gross negligence of such Indemnified Persons), nor shall any Indemnified Person be liable or responsible to any such Purchaser for (i) the validity, effectiveness, sufficiency, enforceability or enforcement of any Note, this Agreement or any other Transaction Document or any instrument or document delivered hereunder or thereunder or relating thereto; (ii) the title of Company to any of the Collateral (as defined in the Security Agreement) or the freedom of any of the Collateral from any prior or other liens or security interests; (iii) the determination, verification or enforcement of Company’s compliance with any of the terms and conditions of the either of the H Notes or G Notes; (iv) the failure by Company to deliver any instrument, agreement, financing statement or other document required to be delivered pursuant to the terms of any H Notes or G Notes; or (v) the receipt, disbursement, waiver, extension or other handling of payments or proceeds made or received with respect to the Collateral, the servicing of the Collateral or the enforcement or the collection of any amounts owing with respect to the Collateral.

(iii) To the extent not paid by Company, each Purchaser agrees to pay to the Agent, promptly on demand, such Purchaser’s Pro Rata (as defined in the Security Agreement) share of the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of the Agent’s counsel and of any experts and agents, that the Agent may incur in connection with: (i) the administration of the Security Agreement or Collateral Agreement or any other Transaction Document; (ii) the custody or preservation of, or the collection from or other realization upon, any of the Collateral; (iii) the exercise or enforcement of any of the rights of the Agent or the holders of H Notes or G Notes; or (iv) the failure by Company to perform or observe any of the provisions hereof. To the extent not indemnified by Company, each Purchaser hereby agrees to hold the Agent harmless, and to indemnify the Indemnified Persons from and against its Pro Rata share of any and all claims, losses, damages, taxes, expenses or liabilities (including without limitation reasonable attorneys fees and expenses) that may be incurred by such Indemnified Persons and that arise out of or are related to the performance by Agent of its services as Agent hereunder, unless such liability shall be caused by the willful misconduct or gross negligence of such Indemnified Persons. The undertakings in this Section shall survive the payment of all Secured Obligations (as defined in the Security Agreement), with respect to the H Notes, and the Security Interest Filing (as defined in the Collateral Agreement), with respect to the G Notes, and the resignation or replacement of the Agent.

(c) No Reliance. Each Purchaser represents to the Agent that it has made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and credit worthiness of the Company, and made its own decision to accept the Notes and to extend credit to the Company independently based on such documents and information as it has deemed appropriate and without reliance upon the Agent or any of its partners, directors, members, officers, agents, designees or employees. Each Purchaser agrees that the Agent shall not have any duty or responsibility to provide such Purchaser with any credit or other information concerning the business, prospects, operations, property, financial and other condition or credit worthiness of the Company.

(d) Agent in Individual Capacity. Tang Capital Partners, LP may make investments, purchase notes and generally engage in any kind of business with the Company as though Tang Capital Partners, LP were not the Agent under the Security Agreement or Collateral Agreement and without notice to or consent of the Purchasers. The Purchasers acknowledge that, pursuant to such activities, Tang Capital Partners, LP, or its affiliates may receive information regarding the Company and its subsidiaries and affiliates (including information that may be subject to confidentiality obligations in favor of any of the foregoing entities) and acknowledge that the Agent shall be under no obligation to provide such information to them unless it receives such information in its capacity as Agent. With respect to its Notes and Debt Warrants, Tang Capital Partners, LP shall have the same rights and powers under this Agreement as any other Purchaser and may exercise the same as though it were not the Agent, and the terms “Purchaser” and “Purchasers” include Tang Capital Partners, LP in its individual capacity.

7.2 Fees and Expenses. Except as provided in Section 7.1(b)(iii), each party shall pay the fees and expenses of its advisors, counsel, accountants and other experts, if any, and all other expenses, incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement and the transactions contemplated hereby; provided, however, that the Company shall pay all documented, actual attorneys’ fees and expenses (including disbursements and out-of-pocket expenses) incurred by the Lead Purchaser or the Agent in connection with (i) the preparation, negotiation, execution and delivery of the Transaction Documents and the transactions contemplated thereunder, which payment shall be made at the Closing (which payment may be withheld from the amount delivered to the Company by the Lead Purchaser at the Closing); and (ii) any amendments, modifications or waivers of this Agreement or any of the other Transaction Documents, including the transactions contemplated hereunder and thereunder. In addition, the Company shall pay all reasonable fees and expenses incurred by the Purchasers or the Agent in connection with the enforcement of this Agreement or any of the other Transaction Documents, including, without limitation, all reasonable attorneys’ fees and expenses; provided, however, that in the event that the enforcement of this Agreement is contested and it is finally judicially determined that the Purchasers or the Agent was not entitled to the enforcement of the Agreement sought, then the Purchasers or the Agent, as the case may be, seeking enforcement shall reimburse the Company for all fees and expenses paid pursuant to this sentence.

7.3 Specific Performance; Consent to Jurisdiction; Venue.

(a) The Company and the Purchasers acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement or the other Transaction Documents were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement or the other Transaction Documents and to enforce specifically the terms and provisions hereof or thereof without the requirement of posting a bond or providing any other security, this being in addition to any other remedy to which any of them may be entitled by law or equity.

(b) The parties agree that venue for any dispute arising under this Agreement will lie exclusively in the state or federal courts located in New York County, New York, and the parties irrevocably waive any right to raise forum non conveniens or any other argument that New York is not the proper venue. The parties irrevocably consent to personal jurisdiction in the state and federal courts of the state of New York. The Company and each Purchaser consent to process being served in any such suit, action or proceeding by mailing a copy thereof 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 in this Section 7.2 shall affect or limit any right to serve process in any other manner permitted by law. The parties hereby waive all rights to a trial by jury.

7.4 Entire Agreement; Amendment. This Agreement and the Transaction Documents contain the entire understanding and agreement of the parties with respect to the matters covered hereby and, except as specifically set forth herein or in the other Transaction Documents, neither the Company nor any Purchaser make any representation, warranty, covenant or undertaking with respect to such matters, and they supersede all prior understandings and agreements with respect to said subject matter, all of which are merged herein. No provision of this Agreement may be waived or amended on behalf of all Purchasers other than by a written instrument signed by the Company and the Purchasers holding at least 66 2/3% of the combined principal amount of the then outstanding Notes, including the Notes that have been issued by way of payment of interest in kind and the Conversion Notes potentially issuable upon exercise of the Debt Warrants (for clarity, even if the Debt Warrants have not been exercised, the underlying Conversion Notes will still be considered Notes for this purpose) (the “Requisite Purchasers”); provided that if any of the rights under this Agreement of any Purchaser then holding Securities are materially diminished or the obligations under this Agreement of any Purchaser then holding Securities are materially increased by such waiver or amendment, in each case in a manner that is not similar in all material respects to the effect on the rights or obligations of other Purchasers, then such waiver or amendment shall not be effective with respect to such adversely affected Purchaser without the written consent of such adversely affected Purchaser. Notwithstanding the foregoing, (a) nothing provided in this Section 7.4 shall limit an individual Purchaser’s right to waive or amend any provision of this Agreement on its own behalf and (b) no provision of this Agreement may be modified or amended that would affect the rights or duties of the Agent hereunder unless the same is in writing and signed by the Agent. The Purchasers acknowledge that any amendment or waiver effected in accordance with this Section 7.4 shall be binding upon each Purchaser (and their permitted assigns) and the Company, including, without limitation, an amendment or waiver that has an adverse effect on any or all Purchasers.

7.5 Notices. Any notice, demand, request, waiver or other communication required or permitted to be given hereunder shall be in writing and shall be effective (a) upon hand delivery, by telecopy, facsimile or electronic transmission to the address(es) or number designated below (if delivered on a business day during normal business hours where such notice is to be received), or the first business day following such delivery (if delivered other than on a business day during normal business hours where such notice is to be received) or (b) on the second business day following the date of mailing by express courier service, fully prepaid, addressed to such address, or upon actual receipt of such mailing, whichever shall first occur.

7.6 Waivers. No waiver by either party of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right accruing to it thereafter.

7.7 Headings. The article, section and subsection headings in this Agreement are for convenience only and shall not constitute a part of this Agreement for any other purpose and shall not be deemed to limit or affect any of the provisions hereof.

7.8 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and assigns. The Purchasers may assign the Securities and its rights under this Agreement and the other Transaction Documents and any other rights hereto and thereto without the consent of the Company.

7.10 Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to any of the conflicts of law principles which would result in the application of the substantive law of another jurisdiction. This Agreement shall not be interpreted or construed with any presumption against the party causing this Agreement to be drafted.

7.11 Survival.

7.12 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and shall become effective when counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart.

7.13 Publicity. The Company agrees that it will not disclose, and will not include in any public announcement, the names of the Purchasers without the consent of the Purchasers, which consent shall not be unreasonably withheld or delayed, or unless and until such disclosure is required by law, rule or applicable regulation, and then only to the extent of such requirement. Notwithstanding the foregoing, the Purchasers consent to being identified in any filings the Company makes with the SEC to the extent required by law or the rules and regulations of the SEC.

7.14 Severability. The provisions of this Agreement are severable and, in the event that any court of competent jurisdiction shall determine that any one or more of the provisions or part of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision or part of a provision of this Agreement and this Agreement shall be reformed and construed as if such invalid or illegal or unenforceable provision, or part of such provision, had never been contained herein, so that such provisions would be valid, legal and enforceable to the maximum extent possible.

7.15 Further Assurances. From and after the date of this Agreement, upon the request of the Purchasers or the Company, the Company and each Purchaser shall execute and deliver such instruments, documents and other writings as may be reasonably necessary or desirable to confirm and carry out and to effectuate fully the intent and purposes of this Agreement and the other Transaction Documents

7.16 Representation of Lead Purchaser. It is acknowledged by each Purchaser that the Lead Purchaser has retained Ropes & Xxxx LLP to act as its counsel in connection with the transactions contemplated by the Transaction Documents and that Ropes & Xxxx LLP has not acted as counsel for any Purchaser, other than the Lead Purchaser, in connection with the transactions contemplated by the Transaction Documents and that none of such Purchasers has the status of a client for conflict of interest or any other purposes as a result thereof.

7.17 Sharing of Payments. Each Purchaser severally agrees that if it receives (i) payment of principal on the Maturity Date (as defined in the Notes) or (ii) payment of the Prepayment Price (as defined in the Notes), in each case in an amount that is ratably more than any other Purchaser (based on the principal amount of the Notes held by such Purchaser (in the case of (i) above) or the Notes held by such Purchaser being prepaid at such time (in the case of (ii) above) relative to the principal amount of all Notes held by the Purchasers (in the case of (i) above) or all Notes held by the Purchasers being prepaid at such time (in the case of (ii) above)), then: (a) the Purchaser receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from the other Purchasers a participation in the Notes held by the other Purchasers (in the case of (i) above) or the Notes held by the other Purchasers being prepaid at such time (in the case of (ii) above) and shall pay to the other Purchasers a purchase price in an amount so that the share of the Notes held by each Purchaser after the receipt of such payment shall be in the same proportion that existed prior to the receipt of such payment; and (b) such other adjustments and purchases of participations shall be made from time to time as shall be equitable to ensure that all Purchasers share any such payment ratably as aforesaid in accordance with the applicable Note; provided that, if all or any portion of a disproportionate payment obtained as a result of such payment is thereafter recovered from the purchasing Purchaser by the Company or any Person claiming through or succeeding to the rights of Company, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest. Each Purchaser that purchases a participation pursuant to this Section 7.17 shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement and the other Transaction Documents with respect to the portion of the Notes purchased to the same extent as though the purchasing Purchaser were the original owner of the Notes purchased. The Company expressly consents to the foregoing arrangements and agrees that any Purchaser holding a participation in a Note so purchased may exercise any and all rights with respect to the participation as fully as if such Purchaser were the original owner of the Note purchased. In addition, without limiting the foregoing, prior to the full release of the security interest in the Collateral, all payments received by any Purchaser in respect of the Collateral shall be received in trust for the benefit of the Agent for the benefit of the holders of the H Notes and G Notes, shall be segregated from other funds of such Purchaser, and shall be forthwith paid over to the Agent for the benefit of the holders of the H Notes and G Notes in the same form as so received (with any necessary endorsement) for distribution as set forth in the Security Agreement and Collateral Agreement.

7.18 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 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 hereto or thereto, shall be deemed to constitute the Purchaser as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any 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.
