Each Grantor recognizes that the provisions of certain of the Loan Documents require Persons that become Subsidiaries of the Company and that are not already parties hereto, to execute and deliver a Grantor Addendum attached hereto as Exhibit O, whereupon each such Person shall become a Grantor hereunder with the same force and effect as if originally a Grantor hereunder on the Closing Date, and each Grantor agrees that its obligations hereunder shall not be discharged, limited or otherwise affected by reason of the same, or by reason of the Secured Party’s actions in effecting the same or in releasing any Grantor hereunder, in each case without the necessity of giving notice to or obtaining the consent of such Grantor or any other Grantor.

5.	CERTAIN PROVISIONS RELATING TO EQUITY INTERESTS

5.1 Ownership; After-Acquired Equity Interests.

(a) Each Grantor will cause the Equity Interests pledged by it or required to be pledged hereunder to constitute at all times 100% of the capital stock or other Equity Interests in each issuer held by such Grantor thereof, and unless the Secured Party shall have given its prior written consent, no Grantor will cause or permit any such issuer to issue or sell any new capital stock, any warrants, options or rights to acquire the same, or other Equity Interests of any nature to any person other than any Grantor, or cause, permit or consent to the admission of any other person other than another Grantor as a stockholder, partner or member of any such issuer.

(b) If any Grantor shall, at any time and from time to time after the Closing Date, acquire any additional capital stock or other Equity Interests in any Person of the types described in the definition of the term “Equity Interests,” the same shall be automatically deemed to be Equity Interests, and to be pledged to the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds pursuant to Section 2.1, and such Grantor will forthwith pledge and deposit the same with the Secured Party (or its agent or bailee) and deliver to the Secured Party (or its agent or bailee) any certificates or instruments therefor, together with the endorsement of such Grantor (in the case of any promissory notes or other Instruments), undated stock powers (in the case of Equity Interests evidenced by certificates) or other necessary instruments of transfer or assignment, duly executed in blank and in form and substance satisfactory to the Secured Party, together with such other certificates and instruments as the Secured Party (or its agent or bailee) may reasonably request (including financing statements or appropriate amendments thereto), and will promptly thereafter deliver to the Secured Party (or its agent or bailee) a fully completed and duly executed amendment to this Agreement in the form of Exhibit J (each, a “Pledge Amendment”) in respect thereof. Each Grantor hereby authorizes the Secured Party to attach each such Pledge Amendment to this Agreement, and agrees that all such Collateral listed on any Pledge Amendment shall for all purposes be deemed Collateral hereunder and shall be subject to the provisions hereof; provided that the failure of any Grantor to execute and deliver any Pledge amendment with respect to any such additional Collateral as required hereinabove shall not impair the security interest of the Secured Party, the Lenders or the MHR Funds in such Collateral or otherwise adversely, affect the rights and remedies of the Secured Party, the other Lenders or the MHR Funds hereunder with respect thereto.

(c) If any Equity Interests (whether now owned or hereafter acquired) included in the Collateral are “uncertificated securities” within the meaning of the Uniform Commercial Code or are otherwise not evidenced by any certificate or instrument, each applicable Grantor will promptly notify the Secured Party thereof and will promptly take and cause to be taken, and will (if the issuer of such uncertificated securities is a person other than a subsidiary of the Grantor) use its best efforts to cause the issuer to take, all actions required under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law, to enable the Secured Party to acquire “control” (within the meaning of such term under Section 8-106 (or its successor provision) of the Uniform Commercial Code) of such uncertificated securities to perfect the security interest of the Secured Party therein.

5.2 Voting Rights. So long as no Event of Default shall have occurred and be continuing (or would occur as a result thereof), each Grantor shall be entitled to exercise all voting and other consensual rights pertaining to its Equity Interests pledged hereunder (subject to each Grantor’s obligations under Section 6.2), and for that purpose the Secured Party will execute and deliver or cause to be executed and delivered to each applicable Grantor all such proxies and other instruments as such Grantor may reasonably request in writing to enable such Grantor to exercise such voting and other consensual rights; provided, however, that such Grantor shall not cast a vote, give consent or exercise any right or take any action which would impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Investment Agreement, this Agreement or any other Loan Document.

5.3 Dividends and Other Distributions. So long as no Event of Default shall have occurred and be continuing (or would occur as a result thereof) and subject in all cases to the terms and conditions of the Loan Documents, all interest, income, dividends, distributions and other amounts payable in cash in respect of the Equity Interests pledged hereunder may be paid to, retained by or used by the Grantors; provided, however, that all such interest, income, dividends, distributions and other amounts shall, at all times after the occurrence and during the continuance of an Event of Default be paid to the Secured Party (or its bailee or agent) and retained by it (or its bailee or agent) as part of the Collateral (except to the extent applied upon receipt to the repayment of the Obligations). The Secured Party (or its bailee or agent) shall also be entitled at all times (whether or not during the continuance of an Event of Default) to receive directly, and to retain as part of the Collateral, (i) all interest, income, dividends, distributions or other amounts paid or payable in cash or other property in respect of any Equity Interests pledged hereunder in connection with the dissolution, liquidation, recapitalization or reclassification of the capital of the applicable issuer to the extent representing an extraordinary, liquidating or other distribution in return of capital, (ii) all additional Equity Interests or other securities or property (other than cash) paid or payable or distributed or distributable in respect of any Equity Interests pledged hereunder in connection with any non-cash dividend, distribution, return of capital, spin-off, stock split, split-up, reclassification, combination of shares or interests or similar rearrangement, and (iii) without affecting any restrictions against such actions contained in the Loan Documents, all additional Equity Interests or other securities or property (including cash) paid or payable or distributed or distributable in respect of any Equity Interests pledged hereunder in connection with any consolidation, merger, exchange of securities, liquidation or other reorganization. All interest, income, dividends, distributions or other amounts that are received by any Grantor in violation of the provisions of this Section shall be received in trust for the benefit of the Secured Party, shall be segregated from other property or funds of such Grantor and shall be forthwith delivered to the Secured Party (or its bailee or agent) as Collateral in the same form as so received (with any necessary endorsements).

6.	REMEDIES

6.1 Events of Default. As used herein, the terms “Default” and “Event of Default” shall refer to (i) such terms as defined in any of the Loan Agreement, Convertible Notes, the 2012 Bridge Notes, the Reimbursement Notes, the 2014 Loan Agreement or any other Loan Document and (ii) the Company’s breach of any representation, covenant or agreement under the Royalty Agreement and the Company’s failure to remedy such breach on or before the 10th day after it occurs; provided, however, that for purposes of this Agreement or any other Security Document, a Stockholder Approval Default shall not constitute an Event of Default unless the Company shall be in breach of its obligations under Section 12.2(b) of the Loan Agreement. In addition, each Grantor hereby acknowledges and agrees that the failure by any Grantor to perform or fulfill any covenant, obligation or agreement contained in this Agreement or the Investment and Exchange Agreement shall also constitute an “Event of Default” for purposes hereunder.

6.2 Remedies.

(a) If an Event of Default shall have occurred and be continuing, the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds shall be entitled to exercise in respect of the Collateral all of the rights, powers and remedies provided for herein or otherwise available to it under the Loan Agreement or any other Loan Document, by law, in equity or otherwise, including, without limitation, all rights and remedies of a secured party under the Uniform Commercial Code. Without limiting the generality of the foregoing, the Secured Party, on its own behalf and on behalf of the Lenders and the MHR Funds, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees that, upon the occurrence and continuance of an Event of Default, at the Secured Party’s request, to assemble the Collateral and make it available to the Secured Party at places which the Secured Party shall reasonably select, whether at such Grantor’s premises or elsewhere.

(b) Subject to Article 7 hereof, the Secured Party shall never be under any obligation to collect, attempt to collect, protect or enforce the Collateral or any security therefor, which each Grantor agrees and undertake to do at their expense, but the Secured Party may do so, but without any obligation to do so, in its discretion at any time after the occurrence and during the continuance of an Event of Default, and at such time the Secured Party shall have the right to take any steps by judicial process or otherwise it may deem proper to effect the collection of all or any portion of the Collateral or to protect or to enforce the Collateral or any security therefor. During the continuance of an Event of Default, upon notice by the Secured Party to the relevant Grantor or Grantors, the Secured Party or its nominee may exercise (A) all voting, consent, corporate and other rights pertaining to the Collateral at any meeting of shareholders, partners or members, as the case may be, of the relevant issuer or issuers of Equity Interests or Collateral or otherwise and (B) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to the Collateral as if it were the absolute owner thereof (including the right to exchange at its discretion any and all of the Collateral upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate structure of any issuer of Equity Interests, the right to deposit and deliver any and all of the Collateral with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Secured Party may determine), all without liability except to account for property actually received by it, but the Secured Party shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) In order to permit the Secured Party to exercise the voting and other consensual rights which it may be entitled to exercise pursuant hereto and to receive all dividends and other distributions which it may be entitled to receive hereunder in the event of and during the continuance of an Event of Default, (i) each Grantor shall promptly execute and deliver (or cause to be executed and delivered) to the Secured Party all such proxies, dividend payment orders and other instruments as the Secured Party may reasonably request, and (ii) without limiting the effect of clause (i) above, such Grantor hereby grants to the Secured Party an irrevocable proxy to vote all or any part of the Collateral and to exercise all other rights, powers, privileges and remedies to which a holder of the Collateral would be entitled (including giving or withholding written consents of shareholders, partners or members, as the case may be, calling special meetings of shareholders, partners or members, as the case may be, and voting at such meetings), which proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Collateral on the record books of the issuer thereof) by any other person (including the issuer of such Collateral or any officer or agent thereof) during the continuance of an Event of Default and which proxy shall only terminate upon the payment in full of the Obligations.

(d) The Secured Party agrees that, notwithstanding anything to the contrary set forth in any Deposit Account Control Agreement or any Account Control Agreement, it shall not issue a Blockage Notice under any Deposit Account Control Agreement or any Account Control Agreement or issue any other orders, notices, requests or other instructions asserting exclusive control over or otherwise directing disposition of funds in any Controlled Deposit Account or any other Controlled Account, unless and until an Event of Default shall have occurred and be continuing.

6.3 Application of Proceeds.

(a) Following the occurrence of an Event of Default, and in connection with the liquidation and sale of any of the Collateral in the exercise of remedies pursuant to the terms of this Agreement and the Loan Documents, the Secured Party shall apply the net proceeds of any action taken by it pursuant to this Section 6.3, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Secured Party and any Secured Party, including reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Loan Documents shall prescribe, and only after such application and after the payment by the Secured Party of any other amount required by any provision of law to any Grantor.

(b) In the event the Secured Party shall pay any taxes, assessments, interests, costs, penalties or expenses incident to or in connection with the collection of the Collateral or protection or enforcement of the Collateral or any security therefore or in connection with any of its rights or duties hereunder, Grantor, upon demand of the Secured Party, shall pay to the Secured Party the full amount thereof with interest at a rate per annum equal to the rate per annum at which interest would then be payable on amounts due under the Convertible Notes, and so long as the Secured Party shall be entitled to any such payment, this Agreement shall operate as security therefor as fully and to the same extent as it operates as security for payment of the other Obligations secured hereunder, and for the enforcement of such repayment the Secured Party shall have every right and remedy provided for enforcement of payment of the Obligations.

(c) The expression “payment in full” or “paid in full” or any similar term or phrase when used in this Agreement shall mean the indefeasible payment in full in cash of all Obligations owing to the Secured Party, the Lenders and the MHR Funds.

(d) Each Grantor shall remain liable to the extent of any deficiency between the amount of all Proceeds realized upon sale, other disposition or collection of the Collateral, and monies held as Collateral pursuant to this Agreement and the aggregate amount of Obligations.

6.4 Collateral Accounts.

(a) Upon the occurrence and during the continuance of an Event of Default, the Secured Party shall have the right to cause to be established and maintained, at its principal office or such other location or locations as it may establish from time to time in its discretion, one or more accounts (collectively, “Collateral Accounts”) for the collection of cash Proceeds of the Collateral. Such Proceeds, when deposited into such Collateral Accounts, shall continue to constitute Collateral for the Obligations and shall not constitute payment thereof until applied as herein provided. The Secured Party shall have sole dominion and control over all funds deposited in any Collateral Account, and such funds may be withdrawn therefrom only by the Secured Party. Upon the occurrence and during the continuance of an Event of Default, the Secured Party shall apply amounts held in the Collateral Accounts in payment of the Obligations in the manner provided for in Section 6.3 hereof.

(b) Upon the request of the Secured Party at any time during the continuance of an Event of Default, each Grantor shall notify Account Debtors that the Accounts or General Intangibles have been collaterally assigned to the Secured Party for its own behalf and on behalf of the Lenders and the MHR Funds and that payments in respect thereof shall be made directly to the Secured Party for its own behalf and on behalf of the Lenders and the MHR Funds. In addition, without notice to the Grantors, the Secured Party, for its own behalf and on behalf of the Lenders and the MHR Funds, may at any time during the continuance of an Event of Default enforce such Grantor’s rights against such Account Debtors and obligors of General Intangibles.

6.5 Grant of License. Each Grantor hereby grants to the Secured Party for its own behalf and on behalf of the Lenders and the MHR Funds an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to any Grantor) to use, license or sublicense any Patent Collateral, Trademark Collateral, Copyright Collateral or Know-How Collateral now owned or licensed or hereafter acquired or licensed by such Grantor (to the extent and only to the extent any of the foregoing does not constitute Excluded Collateral), wherever the same may be located throughout the world, for such term or terms, on such conditions and in such manner as the Secured Party shall determine, whether general, special or otherwise, and whether on an exclusive or nonexclusive basis, and including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof. The use of such license or sublicense by the Secured Party shall be exercised, at the option of the Secured Party, and only upon the occurrence and during the continuation of an Event of Default; provided that any license, sublicense or other transaction entered into by the Secured Party in accordance herewith shall be binding upon each applicable Grantor notwithstanding any subsequent cure of an Event of Default.

6.6 The Grantors Remain Liable. Notwithstanding anything herein to the contrary, (i) each Grantor shall remain liable under all Contracts to which it is a party included within the Collateral (including, without limitation, all Investment Agreements) to perform all of its obligations thereunder to the same extent as if this Agreement had not been executed, (ii) the exercise by the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds of any of its rights or remedies hereunder shall not release any Grantor from any of its obligations under any of such Contracts, and (iii) except as specifically provided for herein below, the Secured Party shall not have any obligation or liability by reason of this Agreement under any of such Contracts, nor shall the Secured Party be obligated to perform any of the obligations or duties of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder. This Agreement shall not in any way be deemed to obligate the Secured Party or any purchaser at a foreclosure sale under this Agreement to assume any of a Grantor’s obligations, duties or liabilities under any Investment Agreement, including, without limitation, any Grantor’s obligations, if any, to manage the business and affairs of the applicable partnership, joint venture, limited liability company, limited liability partnership or other issuer (collectively, the “Partner Obligations”), unless the Secured Party or purchaser otherwise agrees in writing to assume any or all of such Partner Obligations. In the event of foreclosure by the Secured Party in accordance with the terms of this Agreement, then except as provided in the preceding sentence, each applicable Grantor shall remain bound and obligated to perform its Partner Obligations and the Secured Party shall not be deemed to have assumed any Partner Obligations. In the event the Secured Party or any purchaser at such a foreclosure sale elects to become a substitute partner or member in place of a Grantor, the party making such election shall adopt in writing such Investment Agreement and agree to be bound by the terms and provisions thereof; and subject to the execution of such written agreement, each Grantor hereby irrevocably consents in advance to the admission of the Secured Party or any such purchaser as a substitute partner or member to the extent of the Equity Interests acquired pursuant to such foreclosure sale, and agrees to execute any documents or instruments and take any other action as may be necessary or as may be reasonably requested in connection therewith. The powers, rights and remedies conferred on the Secured Party hereunder are solely to protect their interest and privilege in such Contracts, as Collateral, and shall not impose any duty upon them to exercise any such powers, rights or remedies.

6.7 Registration Rights.

(a) If the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds shall determine to exercise its right to sell any or all securities that constitute Collateral pursuant to Section 6.2, and if in the opinion of the Secured Party it is necessary or advisable to have such Collateral, or any portion thereof to be registered under the provisions of the Securities Act, the relevant Grantor shall use its best efforts to cause the issuer thereof to (i) execute and deliver, and cause the directors and officers of such issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Secured Party, necessary or advisable to register such securities, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of such securities, or that portion thereof to be sold and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Secured Party, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Grantor agrees to cause such issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Secured Party shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act.

(b) Each Grantor recognizes that the Secured Party may be unable to effect a public sale of any or all such pledged securities by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise or may determine that a public sale is impracticable or not commercially reasonable and, accordingly, may resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Secured Party shall be under no obligation to delay a sale of any of such pledged securities for the period of time necessary to permit the issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such issuer would agree to do so.

(c) Each Grantor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the pledged securities pursuant to this Section 6.7 valid and binding and in compliance with any and all other applicable requirements of law. Each Grantor further agrees that a breach of any of the covenants contained in this Section 6.7 will cause irreparable injury to the Secured Party, that the Secured Party have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 6.7 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Investment and Exchange Agreement.

6.8 Right of Set-Off. Each Grantor recognizes and agrees that with respect to any time or other deposit, certificate of deposit or any other balance of account standing to the credit of such Grantor on the books of the Secured Party wherever located, the Secured Party has a right of set-off to the full extent permitted by law. Each Grantor further agrees that the Secured Party may exercise such right of set-off at any time when an Event of Default shall occur and be continuing, regardless of the stated maturity of any time deposit or other such credit balance.

6.9 Waivers by the Grantors. Each Grantor, to the greatest extent not prohibited by applicable law, hereby (i) agrees that it will not invoke, claim or assert the benefit of any rule of law or statute now or hereafter in effect (including, without limitation, any right to prior notice or judicial hearing in connection with the Secured Party’s possession, custody or disposition of any Collateral or any appraisal, valuation, stay, extension, moratorium or redemption law), or take or omit to take any other action, that would or could reasonably be expected to have the effect of delaying, impeding or preventing the exercise of any rights and remedies in respect of the Collateral, the absolute sale of any of the Collateral or the possession thereof by any purchaser at any sale thereof, and waives the benefit of all such laws and further agrees that it will not hinder, delay or impede the execution of any power granted hereunder to the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds, but that it will permit the execution of every such power as though no such laws were in effect, (ii) waives all rights that it has or may have under any rule of law or statute now existing or hereafter adopted to require the Secured Party to marshal any Collateral or other assets in favor of such Grantor or any other party or against or in payment of any or all of the Obligations, and (iii) waives all rights that it has or may have under any rule of law or statute now existing or hereafter adopted to demand, presentment, protest, advertisement or notice of any kind (except notices expressly provided for herein or in the Loan Documents) or to require the Secured Party to pursue any third party for any of the Obligations.

7.	THE SECURED PARTY

The Secured Party will hold all items of the Collateral at any time that may be received under this Agreement in accordance with the provisions hereof and the Loan Documents. The obligations of the Secured Party as holder of the Collateral and interests therein and with respect to the disposition thereof, and otherwise under this Agreement and the Loan Documents, are only those expressly set forth in this Agreement and the Loan Documents. The powers conferred on the Secured Party hereunder are solely to protect its interest, on its own behalf and on behalf of the Lenders and the MHR Funds, in the Collateral, and shall not impose any duty upon it to exercise any such powers.

The Secured Party shall not be liable to any Grantor (i) for any loss or damage sustained by such Grantor, or (ii) for any loss, damage, depreciation or other diminution in the value of any of the Collateral that may occur as a result of or in connection with or that is in any way related to any exercise by Secured Party of any right or remedy under this Agreement, any failure to demand, collect or realize upon any of the Collateral or any delay in doing so, or any other act or failure to act on the part of Secured Party, except to the extent that the same is caused by its own gross negligence or willful misconduct. In connection with its appointment and acting hereunder, the Secured Party is entitled to all rights, privileges, protections, immunities and indemnities provided to it under the Loan Documents. Without limiting the foregoing, the Secured Party shall not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Secured Party in good faith.

7.2 Further Assurances. Each Grantor agrees that it will join with the Secured Party to execute and, at its own expense, file and refile under the Uniform Commercial Code such financing statements, continuation statements and other documents and instruments in such offices as necessary or as the Secured Party may reasonably deem necessary or appropriate, and wherever required or permitted by law, in order to perfect and preserve the Secured Party’s security interest in the Collateral, and hereby authorizes the Secured Party to sign and file financing statements and amendments thereto relating to all or any part of the Collateral without the signature of such Grantor, and agrees to do such further acts and things (including, without limitation, making any notice filings with state tax or revenue authorities required to be made by account creditors in order to enforce any Accounts in such state) and to execute and deliver to the Secured Party such additional collateral conveyances, collateral assignments, agreements and instruments (including without limitation subordination and/or intercreditor agreements) as the Secured Party may reasonably require or reasonably deem advisable to perfect, establish, confirm and maintain the security interest and Lien provided for herein, to carry out the purposes of this Agreement or to further assure and confirm unto the Secured Party its rights, powers and remedies hereunder.

(iv) to pay or discharge taxes, Liens or other encumbrances levied or placed on or threatened against the Collateral, the legality or validity thereof and the amounts necessary to discharge the same to be determined by the Secured Party in its reasonably exercised discretion, any such payments made by the Secured Party to become Obligations of the Grantors to the Secured Party, the Lenders and the MHR Funds, due and payable immediately and without demand;

(v) to file any claims or take any action or institute any proceedings in a court of law or equity that the Secured Party may deem necessary or advisable for the collection of any of the Collateral or otherwise to enforce the rights of the Secured Party with respect to any of the Collateral;

(vi) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with any and all of the Collateral as fully and completely as though the Secured Party was the absolute owner of the Collateral for all purposes, and to do from time to time, at the Secured Party’s option and the Grantors’ expense, all other acts and things deemed necessary by the Secured Party to protect, preserve or realize upon the Collateral for its own behalf and on behalf of the Lenders and the MHR Funds and to more completely carry out the purposes of this Agreement;

(b) Except as otherwise provided herein, if any Grantor fails to perform or fulfill any covenant, obligation or agreement contained in this Agreement after written request to do so by the Secured Party (provided, however, that no such request shall be necessary at any time after the occurrence and during the continuance of an Event of Default), the Secured Party may itself perform, or cause the performance of, such covenant or agreement and may take any other action provided hereunder, and the reasonable expenses so incurred in connection therewith shall be payable by the Grantors under Section 8.1.

8.	MISCELLANEOUS

8.1 Indemnity and Expenses. The Secured Party and the Secured Party’s Affiliates and each of their respective officers, directors, managers, partners, shareholders, employees, lenders, advisors, agents and other representatives and any Affiliate of the foregoing, and each of their respective successors and permitted assigns and each Person who controls any of the foregoing, within the meaning of the Securities Act and the Exchange Act, shall be entitled to all indemnities and reimbursement of all fees, costs and expenses and other protections provided in the other Loan Documents, and such indemnification and fee, cost and expense reimbursement provisions in the other Loan Documents are each incorporated by reference herein.

8.2 No Waiver by Course of Conduct; Cumulative Remedies. The rights and remedies of the Secured Party expressly set forth in this Agreement and the Loan Documents are cumulative and in addition to, and not exclusive of, all other rights and remedies available at law, in equity or otherwise. No failure or delay on the part of the Secured Party in exercising any of its rights, powers or privileges shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege or be construed to be a waiver of any Default or Event of Default. No course of dealing between the Grantors and the Secured Party or employees shall be effective to amend, modify or discharge any provision of this Agreement or any other Loan Document or to constitute a waiver of any Default or Event of Default. No notice to or demand upon any Grantor in any case shall entitle such Grantor or any other Grantor to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of the Secured Party to exercise any right or remedy or take any other or further action in any circumstances without notice or demand.

8.3 Grantors’ Obligations Absolute. Each Grantor agrees that its obligations hereunder, and the security interest granted to and all rights, remedies and powers of the Secured Party hereunder, are irrevocable, absolute and unconditional and shall not be discharged, limited or otherwise affected by reason of any of the following, whether or not such Grantor has knowledge thereof:

(i) any change in the time, manner or place of payment of, or in any other term of, any Obligations, or any amendment, modification or supplement to, restatement of, or consent to any rescission or waiver of or departure from, or any other Loan Document or any agreement or instrument delivered pursuant to any of the foregoing;

(ii) the invalidity or unenforceability of any Obligations or any provisions of the Loan Documents or any agreement or instrument delivered pursuant to any of the foregoing;

(iii) the addition or release of Grantors hereunder or the taking, acceptance or release of any Obligations or additional Collateral or other security therefor;

(iv) any sale, exchange, release, substitution, compromise, non-perfection or other action or inaction in respect of any Collateral or other direct or indirect security for any Obligations, or any discharge, modification, settlement, compromise or other action or inaction in respect of any Obligations;

(v) any agreement not to pursue or enforce or any failure to pursue or enforce (whether voluntarily or involuntarily as a result of operation of law, court order or otherwise) any right or remedy in respect of any Obligations or any Collateral or other security therefor, or any failure to create, protect, perfect, secure, insure, continue or maintain any liens in any such Collateral or other security;

(vi) the exercise of any right or remedy available under any of the Loan Documents, at law, in equity or otherwise in respect of any Collateral or other security for any Obligations, in any order and by any manner thereby permitted, including, without limitation, foreclosure on any such Collateral or other security by any manner of sale thereby permitted, whether or not every aspect of such sale is commercially reasonable;

(vii) any bankruptcy, reorganization, arrangement, liquidation, insolvency, dissolution, termination, reorganization or like change in the corporate structure or existence of the Grantors or any other person directly or indirectly liable for any Obligations;

(viii) any manner of application of any payments by or amounts received or collected from any person, by whomsoever paid and howsoever realized, whether in reduction of any Obligations or any other obligations of the Grantors or any other person directly or indirectly liable for any Obligations regardless of what Obligations may remain unpaid after any such application; or

(ix) any other circumstance that might otherwise constitute a legal or equitable discharge of, or a defense, set-off or counterclaim available to, the Grantors, or a surety or guarantor generally, other than the occurrence of the payment in full of the Obligations.

8.4 Amendments, Waivers, etc. No amendment, modification, waiver, discharge or termination of, or consent to any departure by any Grantor from, any provision of this Agreement, shall be effective unless in a writing executed by the parties hereto and delivered to the Secured Party, and then the same shall be effective only in the specific instance and for the specific purpose for which given.

8.5 Subrogation; Termination and Release; Survival. This Agreement shall create a continuing security interest in the Collateral and shall secure the payment and performance of all of the Obligations as the same may arise and be outstanding at any time and from time to time from and after the Closing Date, and shall terminate when all the Obligations have been paid in full (or, in the case of the Convertible Notes, the 2012 Bridge Notes or the Reimbursement Notes, converted in full into shares of the Company’s common stock in accordance with the terms of the Convertible Notes, the 2012 Bridge Notes or the Reimbursement Notes, respectively), and the Secured Party on its own behalf and on behalf of the Lenders and the MHR Funds is hereby subrogated to all of the Grantors’ interests, rights and remedies in respect to the Collateral and all security now or hereafter existing with respect thereto and all guaranties and endorsements thereof and with respect thereto until such time as all of the Obligations have been paid in full, at which time the Secured Party shall execute and deliver to the Grantors all documents reasonably necessary to evidence termination of such security interest and shall return physical possession of any Collateral then held by the Secured Party to the Grantors. For the avoidance of doubt, the Obligations under (a) the Royalty Agreement shall continue to be secured by the Royalty Agreement Collateral and this Agreement shall continue in full force and effect so long as the Royalty Agreement remains in force and effect, notwithstanding the repayment in full of the Obligations under the 2014 Loan Agreement, the Convertible Notes, the 2012 Bridge Notes and the Reimbursement Notes (or, in the case of the Convertible Notes, the 2012 Bridge Notes or the Reimbursement Notes, the conversion in full into shares of the Company’s common stock in accordance with the terms of the Convertible Notes, the 2012 Bridge Notes or the Reimbursement Notes, respectively) and (b) the 2014 Term Loan, to the extent such Obligations were incurred pursuant to Section 3(c) of the 2014 Loan Agreement after the date that all amounts of principal and interest had been repaid in full under the 2014 Term Loan and no further Borrowings (as such term is defined in the 2014 Loan Agreement) were permitted under Section 2 of the 2014 Loan Agreement, shall be secured by the Royalty Agreement Collateral and this Agreement shall continue in full force and effect so long as such Obligations remain outstanding. Upon any sale or other disposition by any Grantor of any Collateral in a transaction expressly permitted hereunder or under or pursuant to the Loan Documents, or any amendment or waiver hereunder or thereunder, the lien and security interest created by this Agreement in and upon such Collateral shall be automatically released; and in connection with any such release or termination, the Secured Party, at the request and expense of the applicable Grantor, will execute and deliver to such Grantor such documents and instruments evidencing such release or termination as such Grantor may reasonably request and will assign, transfer and deliver to such Grantor, without recourse and without representation or warranty, such of the Collateral as may then be in the possession of the Secured Party (or, in the case of any partial release of Collateral, such of the Collateral so being released as may be in its possession). All representations, warranties, covenants and agreements herein shall survive the execution and delivery of this Agreement and any Pledge Amendment or Grantor Addendum; provided, however, that Sections 6.3, 6.5, 6.6, 8.1, 8.5 and 8.13 and all indemnities of the Grantors in favor of the Secured Party contained in this Agreement shall survive, and remain in full force and effect regardless of the termination of the security interest or this Agreement.

8.6 Notices. All notices and other communications provided for hereunder shall be given to the parties in the manner and subject to the other notice provisions set forth in the Loan Documents.

8.7 Severability. To the extent any provision of this Agreement is prohibited by or invalid under the applicable law of any jurisdiction, such provision shall be ineffective only to the extent of such prohibition or invalidity and only in such jurisdiction, without prohibiting or invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction.

8.8 Headings. The headings of the various sections and subsections of this Agreement have been inserted for convenience only and shall not in any way affect the meaning or construction of any of the provisions hereof.

8.9 Bankruptcy; Reinstatement. This Agreement is a legal, valid and binding obligation of each Grantor. This Agreement will remain in full force and effect and enforceable to the maximum extent provided in Section 510(a) of the Bankruptcy Code, and all references herein to a Grantor will be deemed to apply to such entity as debtor-in-possession and to any trustee in bankruptcy for the estate of such entity. Each Grantor further agrees that, if any payment made by any Grantor or other Person and applied to the Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of Collateral are required to be returned by any the Secured Party or any Secured Party to such Grantor, its estate, trustee, receiver or any other party, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, any lien or security interest or other Collateral securing such liability shall be and remain in full force and effect, as fully as if such payment had never been made or, if prior thereto the lien or security interest granted hereby or other Collateral securing such liability hereunder shall have been released or terminated by virtue of such cancellation or surrender), such Lien or other Collateral shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect any Lien or other Collateral securing the obligations of any Grantor in respect of the amount of such payment. Notwithstanding any other provision of this Section, the Secured Party will be entitled to file any necessary pleadings, motions, objections or agreement which assert rights or interests available to unsecured creditors of any Grantor arising under either the Bankruptcy Code or applicable non-bankruptcy law.

8.10 Injunctive Relief. It is hereby agreed and acknowledged that it will be impossible to measure in money the damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them and that in the event of any such failure, an aggrieved Person will be irreparably damaged and will not have an adequate remedy at law. Any such Person shall, therefore, be entitled (in addition to any other remedy to which it may be entitled in law or in equity) to injunctive relief, including, without limitation, specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

If, on and after the Final Withdrawal Date, MHR and its Affiliates shall not hold any of the Secured Loan or the Convertible Notes, a new Secured Party satisfactory to the Company and not less than a majority in principal amount of the Secured Loan or the Convertible Notes, as applicable, shall be appointed by such parties and upon the acceptance of its appointment as Secured Party hereunder, the resigning Secured Party shall be released from all further obligations under this Agreement. Subject to Section 8.11(b), prior to the Final Withdrawal Date, the Secured Party may not assign, transfer or delegate any of its rights or obligations as Secured Party under this Agreement without the prior written consent of the Company.

(b) Notwithstanding anything to the contrary set forth in Section 8.11(a), the MHR Funds’ may assign, transfer or delegate their rights under this Agreement with respect to the Royalty Agreement Collateral to any party to whom the MHR Funds’ have assigned their rights under the Royalty Agreement.

8.12 Counterparts. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute but one contract, and shall become effective when copies hereof which, when taken together, bear the signatures of each of the parties hereto shall be delivered to the Secured Party. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed signature page hereto.
