TO EACH PURCHASER LISTED ON THE ATTACHED

SCHEDULE A WHO IS A SIGNATORY HERETO (COLLECTIVELY WITH THEIR RESPECTIVE

SUCCESSORS AND ASSIGNS, THE “PURCHASERS”):

Ladies and Gentlemen:

THIS SENIOR SECURED NOTE AND WARRANT PURCHASE AGREEMENT (this “Agreement”) is hereby entered into by and among the Purchasers, JAZZ PHARMACEUTICALS, INC., a Delaware corporation (the “Company”), and JPI COMMERCIAL, LLC, a Delaware limited liability company (the “Borrower”), with reference to the following:

The Company has organized the Borrower, a wholly owned Subsidiary of Company, to acquire the Transferred Orphan Assets from Orphan Medical, LLC (“Orphan”), a wholly owned Subsidiary of the Company, and to acquire and hold the LUVOX^® CR Intellectual Property.

The Purchasers have agreed, subject to the terms and conditions hereof, to furnish debt financing to the Borrower by way of the purchase of the Borrower’s senior secured notes in order to provide the Company with funds (1) for the acquisition of the LUVOX^® CR Assets and the marketing and distribution of LUVOX^® CR in the United States, (2) to enable the Company to refinance certain Indebtedness of Orphan owing to the holders of the Orphan Notes, which Indebtedness is guaranteed by the Company and secured by, among other things, certain of the Transferred Orphan Assets, and (3) for general corporate purposes.

Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

NOW THEREFORE, the Purchasers, the Company and the Borrower hereby agree as follows:

SECTION 1. AUTHORIZATION, SALE AND ISSUANCE OF NOTES AND WARRANTS.

Section 1.1 Authorization.

(a) The Borrower has authorized the issue and sale of up to $150,000,000 aggregate principal amount of its 15% Senior Secured Notes (the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13 of this Agreement) due June 24, 2011, which shall be comprised of up to $70,000,000 of Tranche A Notes (the “Tranche A Notes”) and $80,000,000 of Tranche B Notes (the “Tranche B Notes” and, together with the Tranche A Notes, the “Notes”). The Tranche A Notes shall be substantially in the form set forth on Exhibit A-1 and the Tranche B Notes shall be substantially in the form set forth in Exhibit A-2.

(b) The Company has further authorized the issuance and sale to each Purchaser of Warrants (the “Warrants”, such term to include any such warrants issued in substitution therefor pursuant to the terms thereof) to purchase common stock, par value $0.0001 per share, of the Company (“Common Stock”), each substantially in the form set forth in Exhibit B.

Section 1.2 Sale and Purchase of the Notes and Warrants. Subject to the terms and conditions of this Agreement:

(a) (i) The Borrower hereby agrees to issue and sell to each Purchaser signatory hereto at the Initial Closing, and each such Purchaser agrees to purchase from the Borrower, at the Initial Closing, a Tranche A Note in the aggregate principal amount of Tranche A Notes to be purchased set forth opposite such Purchaser’s name on Schedule A attached hereto under the heading “INFORMATION RELATING TO PURCHASERS AT INITIAL CLOSING”, in each case at a purchase price of 100% of the aggregate principal amount of such Tranche A Note. The Borrower further hereby agrees to issue to each such Purchaser a Tranche B Note, and each such Purchaser agrees to acquire from the Borrower, at the Initial Closing, a Tranche B Note in the aggregate principal amount of Tranche B Notes to be exchanged set forth opposite such Purchaser’s name on Schedule A attached hereto under the heading “Purchasers at Initial Closing”, in each case in exchange for an identical aggregate principal amount of Orphan Notes, which shall be all of the Orphan Notes held by such Purchaser. The aggregate principal amount of all Tranche A Notes issued and sold at the Initial Closing shall not exceed $40,000,000.

(ii) The Borrower shall have the right, but not the obligation, to issue and sell, and the Purchasers set forth on Schedule A under the heading “INFORMATION RELATING TO PURCHASERS AT SUBSEQUENT CLOSING”, or Affiliate(s) of such Purchasers designated thereby and reasonably acceptable to the Borrower, agree to purchase from the Borrower, at the Subsequent Closing, Tranche A Notes in an aggregate principal amount (determined by the Borrower) not to exceed $30,000,000, at a purchase price of 100% of the aggregate principal amount of such Tranche A Notes.

(iii) Each Purchaser’s obligation hereunder is several and not joint with the other Purchasers’ obligations such that no Purchaser shall have any obligation or liability to any Person for the performance or nonperformance by any other Purchaser hereunder.

(b) As further consideration for the purchase of the Tranche A Notes by the Purchasers pursuant to Section 1.2(a), and with the Company’s express acknowledgement of its direct and indirect benefit received in connection with such financial accommodations, the Company agrees to issue and deliver at the applicable Closing to each Purchaser then purchasing a Tranche A Note, a Warrant to purchase the number of shares of the Common Stock as determined as follows:

(i) with respect to the Initial Closing, that number of shares of the Common Stock set forth opposite such Purchaser’s name on Schedule A attached hereto under the heading “INFORMATION RELATING TO PURCHASERS AT INITIAL CLOSING”; and

(ii) with respect to the Subsequent Closing, that number of shares of the Common Stock as shall equal the quotient obtained by dividing (a) 20% of the principal amount of the Tranche A Note purchased by such Purchaser at the Subsequent Closing by (b) the Subsequent Closing Exercise Price (as defined below), and rounding down the resulting quotient to the nearest whole share of Common Stock.

In the case of the Warrants issued at the Initial Closing, the exercise price per share of such Warrants shall be $14.23. In the case of the Warrants issued at the Subsequent Closing, the exercise price per share shall be the greater of (i) $2.00 or (ii) the product of 1.2 times the volume weighted average closing price (as based on price quotations published by a nationally recognized stock quotation service reasonably agreed upon by the Borrower, the Company and the applicable Purchaser) of the Company’s Common Stock for the period of 30 consecutive days ending on the date notice of the Subsequent Closing is given pursuant to Section 1.3(a) (the “Subsequent Closing Exercise Price”).

(c) The Borrower, the Company and each Purchaser hereby acknowledge and agree that the Tranche A Notes and Warrants issued in accordance with this Agreement constitute an “investment unit” for the purposes of Section 1273(c)(2)(A) of the Code. In accordance with Sections 1273(c)(2)(A) and 1273(b)(2) of the Code, the issue price of the investment unit is 100% of the aggregate principal amount of the Tranche A Note set forth opposite each such Purchaser’s name on Schedule A. Allocating that issue price between the Tranche A Note and Warrant issued at the Initial Closing based on their relative fair market values, as required by Section 1273(c)(2)(B) of the Code and Treasury Regulation Section 1.1273-2(h)(1), results in (i) the Tranche A Note having an

issue price of 95.06% of the aggregate principal amount of such Note and (ii) the Warrant having a purchase price of 4.94% of the aggregate principal amount of such Tranche A Note. The allocation of the issue price for Tranche A Notes and Warrants issued at the Subsequent Closing shall be as reasonably agreed by the Borrower, the Company and the applicable Purchaser at the time of the Subsequent Closing. The Borrower, the Company and each Purchaser agree to prepare their respective federal income tax returns in a manner consistent with the foregoing agreement.

Section 1.3 Closings. (a) The issuance and sale of the Tranche A Notes and the exchange of the Tranche B Notes, in each case pursuant to Section 1.2(a)(i), and the issuance and delivery of the accompanying Warrants, shall occur at a closing (the “Initial Closing”) to be held at the offices of the Company, 3180 Porter Drive, Palo Alto, California 94304, at 10:00 a.m. local time, on March 17, 2008. The issuance and sale of the Tranche A Notes pursuant to Section 1.2(a)(ii) (if any), and the issuance and delivery of the accompanying Warrants, shall occur at a closing (the “Subsequent Closing” and, together with the Initial Closing, the “Closings”) to be held at the such offices of the Company, at 10:00 a.m. local time, on a Business Day determined by the Borrower and the Company and specified in a notice from the Borrower and the Company to the Purchaser of such Tranche A Notes that the Borrower intends to issue and sell such Tranche A Notes and Warrants on such date, which in any case shall be not less than three Business Day after the date of delivery of such notice. Notwithstanding the foregoing, the Initial Closing or the Subsequent Closing may be held at such other place and time as may be agreed upon by the Borrower, the Company, and all of the applicable Purchasers, except that the Subsequent Closing shall in no event occur after January 31, 2009. For the avoidance of doubt, the Closings described in this Section 1.3 shall be subject in all cases to satisfaction of the conditions set forth in Section 4 hereof.

(b) At the Initial Closing, the Borrower will deliver to, or at the direction of, each Purchaser purchasing a Tranche A Note and/or exchanging Tranche B Note at the Initial Closing a Tranche A Note in the form of a single Tranche A Note and/or a Tranche B Note in the form of a single Tranche B Note, as applicable, in each case dated the date of the Initial Closing and registered in such Purchaser’s name, against (i) in the case of Tranche A Notes, delivery by such Purchaser to the Borrower of immediately available funds in the amount of the purchase price therefor by wire transfer to the account of the Borrower, identified in writing by the Borrower prior to such Initial Closing, and (ii) in the case of Tranche B Notes, delivery of Orphan Notes in the aggregate principal amount of the Tranche B Notes to be exchanged therefor; provided that the Borrower and any holder of Orphan Notes that is unable to deliver such Orphan Notes at the Initial Closing agree that, pending subsequent delivery of such Orphan Notes, such exchange shall for all purposes of this Agreement be deemed to have occurred at the Initial Closing and the Borrower shall hold the Tranche B Notes to which such holder is entitled in trust for, and deliver the same to, such holder upon receipt of such Orphan Notes. It is expressly acknowledged and agreed by all of the parties to this Agreement that (y) upon consummation of the issuance and sale of the Tranche A Notes and accompanying Warrants and the exchange (or deemed exchange) of the Tranche B Notes for Orphan Notes at the Initial Closing, all outstanding Orphan Notes shall be continued as Tranche

B Notes hereunder and the Lien of the Collateral Agent on behalf of the holders of Orphan Notes shall be continued as security for the obligations of the Credit Parties under this Agreement, the Notes, and the other Related Documents, and (z) all Orphan Notes (including any such Orphan Notes to be subsequently delivered as agreed pursuant to this paragraph (b)) shall be cancelled and no longer be outstanding and the Orphan Note Purchase Agreement and the Related Documents (as defined in the Orphan Note Purchase Agreement) (other than the Warrants (as defined in the Orphan Note Purchase Agreement)) shall terminate and have no further force or effect, except those provisions that are expressly stated to survive such termination or the payment of the Orphan Notes or expressly continued under the Related Documents (as defined herein).

(c) At the Subsequent Closing, the Borrower will deliver to or at the direction of the Purchaser purchasing a Tranche A Note at the Subsequent Closing a Tranche A Note in the form of a single Tranche A Note, dated the date of the Subsequent Closing and registered in such Purchaser’s name, against delivery by such Purchaser to the Borrower of immediately available funds in the amount of the purchase price therefor by wire transfer to the account of the Borrower, identified in writing by the Borrower prior to such Closing.

(d) At each Closing, the Company will deliver to or at the direction of each Purchaser purchasing a Tranche A Note at such Closing a Warrant dated the date of such Closing and registered in the name of such Purchaser, and evidencing the right of such Purchaser to purchase that number of shares of the Company’s Common Stock as determined in accordance with the provisions of Section 1.2(b).

Section 1.4 Payment Terms of the Notes. The Notes shall bear interest, in the amounts and payable at the times set forth therein, and shall be due and payable in full on the maturity date set forth therein or as otherwise provided for under this Agreement without defense, set off or counterclaim of any sort. All payments required to be made under the Notes shall be made in the manner and to the account of each Purchaser as set forth in the Notes.

SECTION 2. COMPANY GUARANTY.

Section 2.1 Background. The Company hereby acknowledges and affirms that, as the sole beneficial owner of all of the membership interests of the Borrower, it will directly or indirectly receive certain benefits from the credit accommodations provided for under this Agreement and is therefore willing to guaranty the prompt payment and performance of the Obligations of the Borrower, on the terms set forth in this Section 2.

Section 2.2 Company Guaranty. For value received and in consideration for the Purchasers’ execution of this Agreement and the purchase of the Notes, the Company unconditionally guarantees (a) the full and prompt payment when due, whether at maturity or earlier, by reason of acceleration or otherwise, and at all times thereafter, of all of the indebtedness and obligations of every kind and nature of the Borrower to each Purchaser, or any permitted assignee of any Purchaser, pursuant to the terms of this Agreement and the other Related Documents, howsoever created, arising or evidenced, whether direct or indirect, absolute

or contingent, joint or several, now or hereafter existing, or due or to become due, and howsoever owned, held or acquired by such Purchaser, whether through discount, premium, purchase, direct loan or as collateral or otherwise, and whether principal, interest, fees, costs, expenses or otherwise (including without limitation any interest, Make-Whole Amount, fees or expenses accruing following the commencement of any insolvency, receivership, reorganization or bankruptcy case or proceeding relating to the Borrower, whether or not a claim for post-petition interest, Make-Whole Amount, fees or expenses is allowed in such case or proceeding); and (b) the prompt, full and faithful discharge by the Borrower of each and every term, condition, agreement, representation and warranty now or hereafter made by the Borrower to the Purchasers under this Agreement and the other Related Documents (all such indebtedness and obligations listed in (a) and (b) of this sentence being hereinafter referred to as the “Obligations”). The Company further agrees to pay all reasonable out-of-pocket costs and expenses, including, without limitation, all court costs and reasonable attorneys’ fees paid or incurred by any Purchaser in collecting all or any part of the Obligations from, or in prosecuting or defending any action against, the Company. All amounts payable by the Company under this Section 2 shall be payable upon demand and shall be made in lawful money of the United States, in immediately available funds.

Section 2.3 No Fraudulent Conveyance. It is intended that the Company’s guaranty under this Section 2 (the “Company Guaranty”), and any Liens granted by the Company to secure the Company Guaranty, do not constitute a “Fraudulent Conveyance” (as hereinafter defined). Consequently, the Company agrees that if the Company Guaranty, or any Liens securing the Company Guaranty, would, but for the application of this sentence, constitute a Fraudulent Conveyance, the Company Guaranty and each such Lien shall be valid and enforceable only to the maximum extent that would not cause the Company Guaranty or such Lien to constitute a Fraudulent Conveyance, and the Company Guaranty or the other Related Documents providing for such Lien shall automatically be deemed to have been amended accordingly at all relevant times. For purposes hereof, “Fraudulent Conveyance” means a fraudulent conveyance under Section 548 of the Bankruptcy Code or a fraudulent conveyance or fraudulent transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, nation or other governmental unit, as in effect from time to time.

Section 2.4 Unconditional Guaranty. The Company hereby agrees that its obligations under the Company Guaranty shall be unconditional, irrespective of (i) the validity or enforceability of the Obligations or any part thereof, or of any Notes, Related Documents or other document evidencing all or any part of the Obligations, (ii) the absence of any attempt to collect from the Borrower or any other guarantor of all or any part of the Obligations or other action to enforce the same, (iii) the waiver or consent by any Purchaser with respect to any provision of any instrument evidencing the Obligations, or any part thereof, or any other agreement heretofore, now or hereafter executed by the Borrower or any other guarantor of all or any part of the Obligations, and delivered to such Purchaser, (iv) failure by any Purchaser or the Collateral Agent to take any steps to perfect and maintain its security interest in, or to preserve its rights to, any security or collateral for the Obligations or any guaranty, (v) the existence or nonexistence of any defenses which may be available to the Borrower or any other guarantor of

all or any part of the Obligations, (vi) the institution of any proceeding under Chapter 11 of Title 11 of the United States Code (11 U.S.C. § 101 et seq.), as amended (the “Bankruptcy Code”), or any similar proceeding, by or against the Borrower or any other guarantor, or any Purchaser’s election in any such proceeding of the application of Section 1111(b)(2) of the Bankruptcy Code, (vii) any borrowing or grant of a security interest by the Borrower, as debtor-in-possession, under Section 364 of the Bankruptcy Code (or use of cash collateral under Section 363 of the Bankruptcy Code), (viii) the disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of the Purchasers’ claim(s) for repayment of the Obligations, or (ix) any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor other than the indefeasible payment in full of all Obligations.

Section 2.5 Waiver. The Company hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of receivership or bankruptcy of the Borrower or other guarantors, protest or notice with respect to the Obligations and all demands whatsoever, and covenants that the Company Guaranty will not be discharged, except by complete and indefeasible payment and performance of the Obligations. The Company further waives notice of (i) acceptance of the Company Guaranty, (ii) the existence or incurring from time to time of any Obligations guarantied hereunder, and (iii) the existence of any Default or Event of Default, the making of demand, nonpayment, or the taking of any action by any Purchaser or the Collateral Agent, under this Agreement or any of the other Related Documents. At any time that the Notes become due and payable, whether by maturity or acceleration, any holder of a Note may, in its sole election (regardless of whether the liability of Borrower or any other guarantor of all or any part of the Obligations has matured or may then be enforced), proceed directly and at once, without notice, against the Company to collect and recover the full amount or any portion of the Obligations, without first proceeding against the Borrower or any other guarantor, or against any security or collateral for the Obligations. The Company agrees that the Company Guaranty constitutes a guarantee of payment when due and not of collection.

Section 2.6 Authorization. The Purchasers and the Collateral Agent are hereby authorized, without notice or demand and without affecting the liability of the Company hereunder, at any time and from time to time to (i) renew, extend, accelerate or otherwise change the time for payment of, or other terms relating to, the Obligations or otherwise modify, amend or change the terms of this Agreement, any Note or any other Related Document (subject to the terms hereof and thereof), now or hereafter executed by the Borrower, the Company or any other guarantor and delivered to any of the Purchasers; (ii) accept partial payments on the Obligations; (iii) take and hold security or collateral for the payment of the Obligations guaranteed hereby, or for the payment of the Company Guaranty, or for the payment of any other guaranties of the Obligations, and exchange, enforce, waive and release any such security or collateral; (iv) apply such security or collateral and direct the order or manner of sale or other disposition thereof as in its discretion it may determine; and (v) settle, release, compromise, collect or otherwise liquidate the Obligations and any security or collateral therefor in any manner, without affecting or impairing the obligations of the Company hereunder.

Section 2.7 Responsibility. The Company hereby assumes responsibility for keeping itself informed of the financial condition of the Borrower and any and all endorsers and/or other guarantors of any instrument or document evidencing all or any part of the Obligations and of all other circumstances bearing upon the risk of nonpayment of the Obligations or any part thereof, and the Company hereby agrees that neither the Purchasers nor the Collateral Agent shall have any duty to advise the Company of information known to any Purchaser or the Collateral Agent regarding such condition or any such circumstances or to undertake any investigation. If any of the Purchasers or the Collateral Agent, each in their respective discretion, undertakes at any time or from time to time to provide any such information to the Company, such Purchaser or the Collateral Agent, as applicable, shall be under no obligation to update any such information or to provide any such information to the Company on any subsequent occasion. The Company further acknowledges that the Company has examined or had the opportunity to examine this Agreement and the other Related Documents, and waives any defense which may exist resulting from the Company’s failure to receive or examine at any time this Agreement or the other Related Documents.

Section 2.8 Consent. The Company consents and agrees that none of the Purchasers or the Collateral Agent shall be under any obligation to marshal any assets in favor of the Company or against or in payment of any or all of the Obligations. The Company further agrees that, to the extent that the Borrower, the Company or any other Person makes a payment or payments to the Purchasers, or any Purchaser receives any proceeds of collateral, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to the Borrower, its estates, trustees, receivers or any other Person, including, without limitation, the Company, under any bankruptcy law, state or federal law, common law or equitable theory, then to the extent of such payment or repayment, the Obligations or the part thereof which has been paid, reduced or satisfied by such amount, and the Company’s obligations hereunder with respect to such portion of the Obligations, shall be reinstated and continued in full force and effect as of the date such initial payment, reduction or satisfaction occurred.

Section 2.9 Transfer. Subject to the provisions of Section 13, any Purchaser may sell or assign the Obligations or any part thereof, or grant participations therein, pursuant to the terms of this Agreement and in any such event, each and every immediate or remote assignee or holder of, or participant in, all or any of the Obligations shall have the right to enforce the Company Guaranty, by suit or otherwise, for the benefit of such assignee, holder or participant, as fully as if herein by name specifically given such right, but each Purchaser shall have an unimpaired right, prior and superior to that of any such assignee, holder or participant, to enforce the Company Guaranty for the benefit of such Purchaser, as to any part of the Obligations retained by such Purchaser.

Section 2.10 Continuation. The Company Guaranty shall continue in full force and effect (and may not be revoked or terminated), and the Purchasers shall be entitled to purchase the Notes on the faith hereof, until such time as all of the Obligations have been indefeasibly paid and satisfied in full.

Any and all rights of any nature of the Company to subrogation, contribution, reimbursement or indemnity and any right of the Company to recourse to any assets or property of, or payment from, the Borrower or any other guarantor of all or any part of the Obligations as a result of any payments made or to be made hereunder for any reason, are hereby unconditionally waived by the Company, and the Company shall not at any time exercise any of such rights unless and until all of the Obligations have been indefeasibly paid and satisfied in full.

So long as an Event of Default exists, no payment of any kind (by voluntary payment, prepayment, acceleration, setoff or otherwise) of any portion of the Subordinated Debt may be made by Borrower or received or accepted by the Company at any time. Until such time as the Obligations have been indefeasibly paid and satisfied in full, the Company will not (i) obtain any Lien on any property of the Borrower to secure the Subordinated Debt, or (ii) commence any lawsuit, action or proceeding of any kind against the Borrower to recover all or any part of the Subordinated Debt. Any payments received by the Company in violation of this Section 2.12 shall be held in trust for and immediately remitted to the Purchasers.

SECTION 3. SECURITY INTERESTS.

Section 3.1 Grant of Security Interests. To secure the full and prompt payment and performance of the Obligations and the Company Guaranty, including all renewals, extensions, restructurings and refinancings of any or all of the foregoing, each of the Borrower and the Company hereby grants to the Collateral Agent, for the benefit of the holders of the Notes, a continuing Lien in and to all right, title and interest of Borrower and the Company in the following property, respectively, of the Borrower and the Company, whether now owned or existing or hereafter acquired thereby or arising and regardless of where located, including the products and proceeds thereof (all being collectively referred to as the “Collateral”):

Accounts;

ii)

Deposit Accounts (as defined in the UCC);

iii)

Documents of Title;

iv)

Equipment;

General Intangibles;

vi)

Inventory;

vii)

Investment Property; and

viii)

Other Collateral;

provided, however, that notwithstanding any of the other provisions set forth in this Section 3, this Agreement shall not constitute a grant of a security interest in (a) any ownership interests of any Foreign Subsidiary or (b) any property to the extent that such grant of a security interest is prohibited by any requirements of law of a Governmental Authority, requires a consent not obtained of any Governmental Authority pursuant to such requirement of law or is prohibited by, or constitutes a breach or default under or results in the termination of or requires any consent

not obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to such property or any applicable shareholder or similar agreement, except to the extent that such requirement of law or the term in such contract, license, agreement, instrument or other document or shareholder or similar agreement providing for such prohibition, breach, default or termination or requiring such consent is ineffective under applicable law.

Section 3.2 Perfection of Security Interests. Each of the Borrower and the Company hereby authorizes the Collateral Agent to prepare and file such financing statements or amendments thereof (including financing statements and amendments thereof describing the Collateral as “all assets” or “all personal property” or words to that effect) as the Collateral Agent or the Purchasers may from time to time deem necessary or appropriate in order to perfect and maintain the security interests granted hereunder in accordance with the UCC or the Uniform Commercial Code of any applicable jurisdiction. Each of the Borrower and the Company shall, at the Collateral Agent’s request, at any time and from time to time, execute and deliver to the Collateral Agent within ten (10) Business Days of such request, such documents and other agreements and instruments (and pay the cost of filing or recording the same in all public offices deemed reasonably necessary or desirable by the Collateral Agent or the Purchasers) and do such other acts and things as the Collateral Agent may deem necessary or desirable in order to establish and maintain a valid, attached and perfected security interest in the Collateral in favor of the Collateral Agent for the benefit of the Purchasers (free and clear of all other liens, claims and rights of third parties whatsoever, whether voluntarily or involuntarily created, except as otherwise permitted by Section 10.3) to secure payment of the Obligations, and in order to facilitate the collection of the Collateral. Each of the Borrower and the Company irrevocably hereby makes, constitutes and appoints the Collateral Agent (and all Persons designated by the Collateral Agent for that purpose) as the Borrower’s and the Company’s respective true and lawful attorney and agent-in-fact to file such financing statements and other similar documents, agreements and instruments as may be necessary to preserve and perfect the Collateral Agent’s security interest in the Collateral. Each of the Borrower and the Company acknowledges and agrees that the Collateral is intended to encompass all assets and property of Borrower and the Company (subject to the terms and conditions of this Agreement) and if at any time Borrower or the Company acquires any interest in any assets or property a security interest in which cannot be perfected by the filing of a financing statement in the appropriate jurisdiction or any assets or property a security interest in which can be perfected by the filing of a financing statement in the appropriate jurisdiction but that are not covered by the security interest grant set forth above (e.g., commercial tort claims, it being certified by Borrower or the Company that it has no interest in any commercial tort claims as of the Initial Closing), then the Borrower or the Company, as appropriate, will, if reasonably requested by the Collateral Agent, cause such assets or property to become part of the Collateral and take such reasonable steps as the Collateral Agent or the Purchasers may require in accordance with this Section 3.2. Each of the Borrower and the Company hereby agree to give the Collateral Agent prompt notice of any commercial tort claim filed by the Company or any of its subsidiaries.

Section 3.3 Possession of Collateral and Related Matters. Until an Event of Default has occurred and is continuing, both of the Borrower and the Company shall have the right, except as otherwise provided in this Agreement, to (a) sell or lease any of their Inventory normally held thereby for any such purpose, (b) use and consume any raw materials, work in process or other materials normally held thereby for such purpose and (c) dispose of any assets to the extent permitted under Section 10.2. If any Inventory is in the possession or control of any warehouseman or the Company’s or the Borrower’s, as applicable, agents or processors, then the Borrower or the Company, as applicable, shall, upon the Collateral Agent’s request, notify such warehouseman, agent or processor of the Collateral Agent’s security interest in such Inventory and, upon the Collateral Agent’s request, instruct them to hold all such Inventory for the Collateral Agent’s account and subject to the Collateral Agent’s instructions.

Section 3.4 Continuing Security Interest; Termination.

(a) This Section 3 creates a continuing security interest in the Collateral and shall (i) remain in full force and effect until the payment or satisfaction in full of the Obligations (other than any contingent indemnity obligations), (ii) be binding upon the Borrower and the Company, and their respective successors and assigns and (iii) except to the extent that the rights of any transferor or assignor are limited by the terms of this Agreement, inure, together with the rights and remedies of the Collateral Agent, to the benefit of the Collateral Agent and the holders of Notes. The Borrower’s and the Company’s successors and assigns shall include, without limitation, a receiver, trustee or debtor-in possession thereof or therefor.

(b) Upon the payment in full in cash of the Obligations (other than any contingent indemnity obligations), the security interests granted pursuant to this Section 3 shall terminate and all rights to the Collateral shall revert to the Borrower and the Company, as applicable. Upon any such termination of the security interests hereunder, the Borrower and the Company shall each be entitled to the return, upon its request and at its expense, of such of the Collateral held by the Collateral Agent as shall not have been sold or otherwise applied pursuant to the terms hereof and the Collateral Agent will, at the Borrower’s and the Company’s expense, execute and deliver to the Borrower or the Company, as applicable such other documents as they shall reasonably request to evidence such termination. In connection with any transfers, sales or other dispositions of assets permitted under this Agreement or any other release of Collateral that may be required in connection with any other action which is permitted by this Agreement, the Collateral Agent will release and terminate the Liens granted under this Agreement with respect to such assets.

Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not reasonably be expected to be, individually or in the aggregate, Material.

No Credit Party is engaged principally or as one of its activities, in the business of extending credit for the purpose of “purchasing” or “carrying” any “margin stock” as such terms are defined in Regulation U of the Federal Reserve Board as now and from time to time hereafter in effect. None of the proceeds of the Notes will be used, directly or indirectly, for the purpose of purchasing or carrying any margin stock or for any other purpose which might cause any of the Notes under this Agreement to be considered a “Purpose credit” within the meaning of Regulations T, U, or X of the Board of Governors of the Federal Reserve Board.

Section 5.16 Foreign Assets Control Regulations, Etc. Neither the sale of the Notes by the Borrower hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto. Without limiting the foregoing, neither the Company nor any of its Subsidiaries (a) is or will become a blocked person described in Section 1 of Executive Order 13224 of September 23, 2001 Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism (66 Fed. Reg. 49049 (2001)) or (b) engages or will engage in any dealings or transactions, or be otherwise associated, with any such person.

Section 5.17 Status under Certain Statutes. No Credit Party is an “investment company” registered or required to be registered subject to regulation under the Investment Company Act of 1940, as amended, or is subject to regulation under the Public Utility Holding Company Act of 1935, as amended, or the Federal Power Act, as amended.

SECTION 6. REPRESENTATIONS OF THE PURCHASERS.

Section 6.1 Representations to the Borrower and the Company. Each Purchaser represents and warrants to the Borrower and the Company, severally and not jointly, with respect to its purchase of the Notes and, to the extent applicable, Warrants as follows:

(a) Purchaser is purchasing the Note and Warrant for investment for Purchaser’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act. Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and, in any case, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of investing in the Securities. Purchaser has not been formed for the purpose of investing in the Securities.

(b) Purchaser understands that the Note and Warrant that Purchaser is purchasing have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein.

(c) Purchaser further acknowledges and understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available and the Securities may be imprinted with a legend indicating such restrictions on the transferability thereof.

(d) Purchaser understands that the Securities are presently characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company and the Borrower in a transaction not involving a public offering and that under such laws and applicable regulations, such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, Purchaser represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

(e) Purchaser represents that at least one of the following statements is an accurate representation as to each source of funds (a “Source”) to be used by such Purchaser to pay the purchase price of the Notes to be purchased by such Purchaser hereunder:

(i) if such Purchaser is an insurance company, the Source does not include assets allocated to any separate account maintained by you in which any employee benefit plan (or its related trust) has any interest, other than a separate account that is maintained solely in connection with your fixed contractual obligations under which the amounts payable, or credited, to such plan and to any participant or beneficiary of such plan (including any annuitant) are not affected in any manner by the investment performance of the separate account; or

(ii) the Source is either (i) an insurance company pooled separate account, within the meaning of Prohibited Transaction Exemption (“PTE”) 90-1 (issued January 29, 1990), or (ii) a bank collective investment fund, within the meaning of the PTE 91-38 (issued July 12, 1991) and, except as Purchaser has disclosed to the Company in writing pursuant to this paragraph (b), no employee benefit plan or group of plans maintained by the same employer or employee organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund; or

(iii) the Source constitutes assets of an “investment fund” (within the meaning of Part V of the QPAM Exemption) managed by a “qualified professional asset manager” or “QPAM” (within the meaning of Part V of the QPAM Exemption), no employee benefit plan’s assets that are included in such investment fund, when combined with the assets of all other employee benefit

plans established or maintained by the same employer or by an affiliate (within the meaning of Section V(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, exceed 20% of the total client assets managed by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a person controlling or controlled by the QPAM (applying the definition of “control” in Section V(e) of the QPAM Exemption) owns a 5% or more interest in the Company and (x) the identity of such QPAM and (y) the names of all employee benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this paragraph (iii); or

(iv) the Source is a governmental plan; or

(v) the Source is one or more employee benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans, each of which has been identified to the Company in writing pursuant to this paragraph (v); or

(vi) the Source does not include assets of any employee benefit plan, other than a plan exempt from the coverage of ERISA.

As used in this Section 6.1, the terms “employee benefit plan,” “governmental plan,” “party in interest” and “separate account” shall have the respective meanings assigned to such terms in Section 3 of ERISA.

Section 6.2 Exculpation of the Purchasers. Each Purchaser acknowledges that it is not relying upon any Person (including the Collateral Agent or any other Purchaser), other than the Company and its officers (acting in their respective capacities as representatives of the Company), in deciding to invest and in making its investment in the purchase of the Notes and Warrants. Each Purchaser agrees that none of the Collateral Agent, the other Purchaser or any of their respective controlling Persons, officers, directors, partners, agents or employees shall be liable to such Purchaser for any losses incurred by such Purchaser in connection with its purchase of the Notes and Warrants.

In addition to paying the remaining outstanding principal amount and the interest due on the Notes on the maturity date thereof or upon acceleration of the Notes pursuant to Section 12, all as guaranteed by the Company Guaranty, if a Mandatory Prepayment Event occurs, the Borrower and the Company each agree as follows:

(a) Promptly upon the consummation of such Mandatory Prepayment Event, the Borrower shall give the holders of the Notes written notice of such Mandatory Prepayment Event with a description in reasonable detail of such Mandatory Prepayment Event including, the calculation of the Net Proceeds received in connection therewith and, for each holder of a Note, the amount of such holder’s Pro Rata Portion of such Net Proceeds.

(i) Each holder of a Note shall have the option, exercised by written notice to the Borrower, prior the end of business on the date that is 21 days after receiving notice of the Mandatory Prepayment Event (the “End Release Date”), to require that all or any portion of such holder’s Pro Rata Portion of the Net Proceeds, in such holder’s discretion, be applied as a prepayment in reduction of the outstanding principal balance of the then outstanding Notes then held by such Holder.

(ii) If and to the extent that any holder of a Note declines to require a mandatory prepayment or otherwise waives the provisions of this Section 8.1 in connection with any Mandatory Prepayment Event, in either case in a writing signed by such holder, or, if such holder fails to give notice prior to the End Release Date requiring a full or partial prepayment of such holder’s Note or Notes pursuant to clause (i) above, then an amount equal to such holder’s Pro Rata Portion of the Net Proceeds shall be released from the collateral account and freely available to the Company and its Subsidiaries for all legal purposes permitted by this Agreement.

The Borrower may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of the Notes, in a minimum amount not less than $5,000,000 and in increments of at least $1,000,000 in excess of such minimum, in the case of a partial prepayment, at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount, if any, determined for the prepayment date with respect to such principal amount. The Borrower will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 5 days prior to the date fixed for such prepayment. Each such notice shall specify such date, the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid, and the interest and Make-Whole Amount, if any, to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of Senior Financial Officer specifying the computation of the Make-Whole Amount due in connection with such prepayment, setting forth the details of such computation. In the case of

each partial prepayment of the Notes made pursuant to this Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

Section 8.3 Contingent Required Redemption. If, at any time after end of the calendar quarter in which [ * ], the Annualized Aggregate Net Product Sales of the Company are less than $[ * ], then the Majority Holders may, by notice to the Company and the Borrower, require the Borrower to redeem up to $30,000,000 outstanding principal amount of the Notes at a redemption price equal to par plus all accrued and unpaid interest on the Notes to be redeemed. Such redemption shall occur on a date fixed by the Borrower by notice to the Note holders not less than 30 and not more than 90 days after receipt of notice from the Majority Holders under this Section, and shall be effected pro rata among all holders of Notes according to the aggregate principal amount of Notes held by each such holder.

Section 8.4 Maturity, Surrender, Etc. In the case of each prepayment or redemption of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Borrower shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. All such prepayments and redemptions shall be pro rata as among the Tranche A Notes and Tranche B Notes.

Section 9.2 Insurance. The Borrower will, and will cause each of its Subsidiaries to, and the Company will, and will cause each Subsidiary to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including

The Collateral Agent shall be named as “lender’s loss payee” on all insurance policies relating to any Collateral and as “additional insured” under all liability policies (except Directors’ and Officers’ Insurance, automobile insurance, workers’ compensation, fiduciary liability and employment practices), in each case pursuant to appropriate endorsements in form and substance reasonably satisfactory to the Collateral Agent.

Section 9.6 Minimum Cash Balance. If at any time on or after the date on which financial statements of the Company for the fiscal quarter ended March 31, 2009 are required to be delivered pursuant to Section 7.1, and for so long as, the Annualized Aggregate Net Product Sales of the Company are less than $[ * ] (on or after such date), the Borrower shall maintain a minimum cash balance equal to 15% of the then outstanding principal amount on the Notes in a deposit or other similar demand investment account that is pledged to the Collateral Agent for the benefit of the Purchasers as collateral security for the prompt and full payment of the Notes and which such account is subject to a control account agreement, in form and substance reasonably satisfactory to the Collateral Agent, between the applicable financial intermediary where such account is held and the Collateral Agent.

(a) The Borrower will not, and will not permit its Subsidiaries to, and the Company will not, and will not permit its Subsidiaries to, create, issue, assume, guarantee or otherwise incur or in any manner be or become liable in respect of any Indebtedness, except:

(i) Indebtedness evidenced by the Notes;

(ii) unsecured Indebtedness incurred by the Company or any Domestic Subsidiary of the Company other than the Borrower (or any of the Borrower’s Subsidiaries) so long as no principal of such Indebtedness is scheduled to mature prior to the stated maturity of the Notes;

(iv) secured Indebtedness (hereinafter referred to as the “Permitted Other Secured Indebtedness”) created, issued, assumed, guaranteed or otherwise incurred by the Company or any Domestic Subsidiary of the Company other than the Borrower (or any of the Borrower’s Subsidiaries) so long as no principal of

such Indebtedness is scheduled to mature prior to the stated maturity of the Notes; provided that at the time of creation, issuance, assumption, guarantee or incurrence thereof and after giving effect thereto and to the application of the proceeds thereof, the ratio of (i) Consolidated Secured Indebtedness at such time to (ii) Consolidated EBITDA, as measured for the then trailing four most recently completed fiscal quarters of the Company, shall not be in excess of 3.0 to 1.0;

(v) Indebtedness (hereinafter referred to as the “Permitted Acquisition Indebtedness”) created, issued, assumed, guaranteed or otherwise incurred by the Company or any Subsidiary of the Company other than the Borrower (or any of the Borrower’s Subsidiaries) used to finance (or assumed in connection with) the acquisition of a pharmaceutical or biotechnology product (including by way of the acquisition of stock or other similar ownership interests of the Person owning the target product); provided that at the time of creation, issuance, assumption, guarantee or incurrence thereof and after giving effect thereto and to the application of the proceeds thereof, the aggregate outstanding principal amount of such Indebtedness permitted by this clause (v) shall not exceed three times the lower of:

a. the annualized EBITDA of the Person or product being acquired as measured for the then most recent 12 months ended; and

(vi) Indebtedness represented by currency swaps or letters of credit entered into or issued, as the case may be, in the ordinary course of business of a Credit Party; and

(vii) Any amounts owing under the Settlement Agreements.

(b) The renewal, extension, increase or refunding of any Indebtedness originally permitted to be issued, incurred or outstanding pursuant to Section 10.1(a) shall constitute the issuance of additional Indebtedness which is, in turn, subject to the limitations of the applicable provisions of this Section 10.1.

(c) Any Person that becomes a Subsidiary after the date hereof shall for all purposes of this Section 10.1 be deemed to have created, assumed or incurred at the time it becomes a Subsidiary all Indebtedness of such Person existing immediately after it becomes a Subsidiary which Indebtedness, in turn, shall be subject to the limitations of this Section 10.1 including, for the avoidance of doubt, any exceptions set forth herein.

(d) Each Credit Party, the Collateral Agent and each Purchaser acknowledges and agrees that, notwithstanding the incurrence or assumption of any of the Indebtedness permitted to be incurred or assumed pursuant to Section 10.1(a), the Liens granted to the Collateral Agent for the benefit of the holders of Notes as collateral security for the payment of the Obligations (including, without limitation, the Liens on the Collateral provided for in Section 3 hereof) shall remain in place as valid and enforceable Liens; provided, however, that the Purchasers and the Collateral Agent hereby agree that, in the case of the incurrence or assumption of any Permitted Purchase Money Indebtedness, any Permitted Receivables/Inventory Indebtedness or any Permitted Acquisition Indebtedness, if requested by the Company, the Collateral Agent shall agree, in a writing that is in form and substance reasonably acceptable thereto, with the applicable creditor or creditors holding such Permitted Purchase Money Indebtedness, such Permitted Receivables/Inventory Indebtedness or such Permitted Acquisition Indebtedness, as the case may be, to subordinate any Liens which the Collateral Agent has or holds on the assets being acquired or financed in favor of the Liens expressly permitted to be incurred under Sections 10.3(a)(i), 10.3(a)(ii) and 10.3(c), respectively, in connection with such acquisition.

for ongoing payment of royalties and milestones (but, for the avoidance of doubt, not sales or divestitures of rights in Xyrem^® or monetizations of royalty streams therein) so long as, at the time of such sale, transfer or disposition and after giving effect thereto, no Default or Event of Default shall exist (a “Permitted Product Transfer”);

(d) selling, transferring or otherwise disposing of any Product of the Borrower other than Xyrem^®, Antizol, or LUVOX^® CR so long as, at the time of such sale, transfer or disposition and after giving effect thereto, no Default or Event of Default shall exist (a “Permitted Product Disposition”);

(g) engaging in a transaction whereby any Subsidiary of the Company (other than the Borrower or a direct Subsidiary of the Borrower) merges or consolidates with or into the Company or any Subsidiary that is a Domestic Subsidiary; provided that in any merger or consolidation involving the Company, the Company shall be the surviving or continuing corporation; and,

(h) (i) engaging in licensing agreements between and among the Borrower, the Company and the Collateral Agent according to the terms of, and in the form set forth in, Exhibit C hereto (“Xyrem License Agreement”), Exhibit D hereto (“Antizol License Agreement”), and Exhibit E hereto (“LUVOX^® CR License Agreement”, and together with the Xyrem License Agreement and the Antizol License Agreement, the “JPI Commercial License Agreements”), (ii) selling, transferring or otherwise disposing of any property of the Borrower or any of its Subsidiaries to the Company or any of its Domestic Subsidiaries as set forth in the License Agreements; provided, however, that the provisions of Section 10.2 (c), (e) and (f) shall not apply to the rights and property permitted to be transferred to the Company pursuant to this Section 10.2(h).

Section 10.3 Limitation on Liens. The Borrower will not, and will not permit its Subsidiaries to, and the Company will not, and will not permit its Subsidiaries to, create or incur, or suffer to be incurred or to exist, any Lien (except Permitted Liens) on its or their property, whether now owned or hereafter acquired, or upon any income or profits therefrom; provided, however, that the foregoing shall neither restrict nor operate to prevent:

(a) Liens on property of the Company or any Subsidiary of the Company other than the Borrower (or any of the Borrower’s direct Subsidiaries) created solely for the purpose of securing (i) Permitted Purchase Money Indebtedness so long as (x) such Liens shall not extend to or cover property of the Company or such Subsidiary other than the property so acquired in respect of such Permitted Purchase Money Indebtedness, and (y) the principal amount of the Indebtedness secured by any such Liens shall at no time exceed the original purchase price of such fixed assets and (ii) Permitted Receivables/Inventory Indebtedness;

(c) Liens on property of the Company or any Subsidiary of the Company other than the Borrower (or any of the Borrower’s direct Subsidiaries) created solely for the purpose of securing (or assumed in connection with) Permitted Acquisition Indebtedness, so long as such Liens shall not extend to or cover property of the Company or such Subsidiary other than the property being acquired in connection with such Permitted Acquisition Indebtedness; or

(d) Liens on property of the Company or any Subsidiary of the Company created solely for the purpose of consummating a Permitted Product Transfer permitted by Section 10.2(b), so long as such Liens shall not extend to or cover property of the Company or such Subsidiary other than the property which is the subject of such Permitted Product Transfer.

Section 10.4 Restricted Payments. The Borrower will not, and will not permit its Subsidiaries to, and the Company will not, and will not permit its Subsidiaries to, except as hereinafter provided: declare or pay any dividends (other than, solely in the case of the Company, dividends payable solely in capital stock of the Company), either in cash or property, on any shares of its capital stock of any class; directly or indirectly, or through any Subsidiary or through any Affiliate of the Company, purchase, redeem or retire any shares of its capital stock of any class or any warrants, rights or options to purchase or acquire any shares of its capital stock (other than in connection with the repurchase of common stock by the Company from current or former employees, directors or consultants of the Company upon the termination of their status as such); voluntarily prepay any unsecured Indebtedness permitted pursuant to Section 10.1(a)(ii) or Permitted Other Secured Indebtedness; or make any other payment or distribution, either directly or indirectly or through any Subsidiary, in respect of its capital stock; provided, however, that the foregoing shall neither apply to nor operate to prevent any Subsidiary of the Borrower or the Company from making a dividend or similar distribution to the Borrower, the Company or any Domestic Subsidiary thereof.

Section 10.5 Subsidiaries, Acquisitions and Investments. The Borrower will not, and will not permit its Subsidiaries to, and the Company will not, and will not permit its Subsidiaries to, create or capitalize any Subsidiary after the date hereof, enter into any transaction or series of related transactions in which it acquires all or any significant portion of the assets or capital stock (or other similar equity interests) of another Person or make any other Investments other than Permitted Investments; provided, however, that this Section shall neither apply to nor operate to prevent the Company or any of its Subsidiaries from:

(a) creating and capitalizing a Subsidiary that is a Domestic Subsidiary, acquiring all or a significant portion of the assets of any Person or acquiring all or a significant portion of the capital stock (or other similar equity interests) of another Person if (i) the Company and its Subsidiaries comply with the requirements set forth in Section 9.7(a) in respect of any New Subsidiary created, (ii) any such assets or stock (or other similar equity interests) directly acquired is subject to the continuing security interests set forth in Section 3 subject to any Liens permitted by Section 10.3, and (iii) no Default or Event of Default otherwise exists as of the time of the creation or capitalization of any such New Subsidiary; or

For purposes of this Section 10.5, at any time when a Person becomes a Subsidiary, all Investments of such Person at such time shall be deemed to have been made by such Person, as a Subsidiary, at such time, which Investments, in turn, shall be subject to the limitations of this Section 10.5, including, for the avoidance of doubt, any exceptions set forth herein.

Section 10.6 Transactions with Affiliates.

Neither the Company nor the Borrower nor any other Credit Party shall amend, supplement or otherwise modify its respective certificate of incorporation, bylaws, certificate of formation, or other constituent agreements, as applicable, as in effect on the date hereof in any manner that is materially adverse to the interests of the holders of the Notes or the Warrants.

Section 10.9 Settlement Agreements. Neither the Borrower nor the Company nor any Subsidiary thereof (including, without limitation, Orphan) shall take any action which would adversely affect the ability of such party or that of any other of the Borrower, the Company or any Subsidiary thereof to comply in all respects with, perform, or not breach or default with respect to, any of its obligations in respect of each of the Settlement Agreements, except, solely in the case of the Corporate Integrity Agreement, for such failures to comply or perform, and such breaches and defaults, as would not individually or collectively constitute a Material Breach or Default.

SECTION 12. REMEDIES ON DEFAULT, ETC.

Section 12.1 Acceleration.

(a) If an Event of Default with respect to the Company described in paragraph (g) or (h) of Section 11 (other than an Event of Default described in clause (i) of paragraph (g) or described in clause (vi) of paragraph (g) by virtue of the fact that such clause encompasses clause (i) of paragraph (g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any Event of Default other than those set forth in Section 12.1(a) has occurred and is continuing, the Majority Holders may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c) At any time that the Notes become due and payable under this Section 12.1, whether automatically or by declaration, each Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon and (ii) in the event that the Notes have become due by reason of an Event of Default described in Sections 11(a), (b), (g), (h) or (j), the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. Each of the Company and the Borrower acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for), and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default described in Sections 11(a), (b), (g), (h) or (j), is intended to provide compensation for the deprivation of such right under such circumstances.

Section 12.2 Other Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

Section 12.3 Certain Remedies as to Collateral. If any Event of Default shall have occurred and be continuing, in addition to and not in limitation of any rights or remedies available to the holders of Notes at law or in equity, the Collateral Agent may (and shall, if so directed by the Majority Holders) exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the affected Collateral) and may also (a) notify any or all obligors on the Accounts to make all payments

directly to the Collateral Agent; (b) require the Borrower and the Company to, and the Borrower and the Company hereby agree that they will, at their expense and upon request of the Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Collateral Agent and make it available to the Collateral Agent at a place to be designated by the Collateral Agent which is reasonably convenient to both parties; (c) without notice or demand or legal process, enter upon any premises of the Borrower and the Company and take possession of the Collateral; and (d) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, at such time or times, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Collateral Agent may deem commercially reasonable. The Borrower and the Company agree that, to the extent notice of sale shall be required by law, at least ten (10) days notice to the Borrower and the Company of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. At any sale of the Collateral, if permitted by law, the Collateral Agent may bid (which bid may be, in whole or in part, in the form of cancellation of indebtedness) for the purchase of the Collateral or any portion thereof for the account of the Collateral Agent and/or disclaim all warranties. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Borrower and the Company shall remain liable for any deficiency. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed thereof, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, the Borrower and the Company hereby specifically waive all rights of redemption, stay or appraisal which they have or may have under any law now existing or hereafter enacted. The Collateral Agent shall not be required to proceed against any Collateral but may proceed against the Borrower and the Company directly.

Section 12.4 Appointment of Attorney-in-Fact. Effective upon the occurrence and during the continuation of an Event of Default, the Borrower and the Company hereby constitute and appoint the Collateral Agent as their attorney-in-fact with full authority in the place and stead of the Borrower and the Company and in their name, the Collateral Agent or otherwise, from time to time in the Collateral Agent’s discretion to take any action and to execute any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including: (a) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral; (b) to adjust, settle or compromise the amount or payment of any Account, or release wholly or partly any customer or obligor thereunder or allow any credit or discount thereon; (c) to receive, endorse, and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) above; (d) to file any claims or take any action or institute any proceedings that the Collateral Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral; (e) to sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, assignments, verifications and notices in connection with Accounts and other documents relating to the Collateral; and (f) to execute on behalf of the Company the assignment of the Antizol Contracts, LUVOX^® CR Contracts, and Xyrem Contracts pursuant to Section 12.9. The appointment of the Collateral Agent as the Borrower’s and the Company’s attorney and the Collateral Agent’s rights and powers are coupled with an interest and are irrevocable until no Event of Default shall exist or payment in full and complete performance of all of the Obligations.

Section 12.5 Limitation on Duty of the Collateral Agent with Respect to Collateral. Beyond the safe custody thereof, the Collateral Agent shall have no duty with respect to any Collateral in its possession or control (or in the possession or control of any agent or bailee) or with respect to any income thereon or the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. The Collateral Agent shall not be liable or responsible for any loss or damage to any of the Collateral, or for any diminution in the value thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee or other agent or bailee selected by the Collateral Agent in good faith.

Section 12.6 Application of Proceeds. Upon the occurrence and during the continuance of an Event of Default, (a) the Borrower and the Company irrevocably waive the right to direct the application of any and all payments at any time or times thereafter received by the Collateral Agent from or on behalf of the Borrower and the Company, and the Borrower and the Company hereby irrevocably agree that the Collateral Agent shall have the continuing exclusive right to apply and to reapply any and all payments received at any time or times after the occurrence and during the continuance of an Event of Default against the Obligations in such manner as the Collateral Agent may deem advisable notwithstanding any previous entry by the Collateral Agent upon any books and records and (b) the proceeds of any sale of, or other realization upon, all or any part of the Collateral shall be applied: first, to all fees, costs and expenses incurred by the Collateral Agent or the Purchasers with respect to this Agreement, the other Related Documents or the Collateral; second, to accrued and unpaid interest and any Make-Whole Amount due on the Notes; and third, to the principal amounts of the Obligations outstanding.

Section 12.7 License of Intellectual Property. To the extent permitted under any relevant agreement entered into by the Company or the Borrower relating to its Intellectual Property, the Borrower and the Company hereby grant to the Collateral Agent for the benefit of the holders of Notes, effective only upon the occurrence and during the continuance of any Event of Default hereunder, the non-exclusive limited right and license to use all Intellectual Property owned, or licensed from a third-party by, the Borrower or the Company together with any goodwill associated therewith (to the extent owned by the Borrower or the Company), solely to the extent necessary to enable the Collateral Agent to realize on the Collateral and any successor or assign of the Collateral Agent to enjoy the benefits of the Collateral. This limited right and license shall inure to the benefit of all successors, assigns and transferees of the Collateral Agent and its successors, assigns and transferees, whether by voluntary conveyance, operation of law, assignment, transfer, foreclosure, deed in lieu of foreclosure or otherwise. Such right and license is granted free of charge, without requirement that any monetary payment whatsoever be made to the Borrower and the Company by the Collateral Agent.

Section 12.8 No Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of the Collateral Agent or any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice the Collateral Agent’s or such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon the Collateral Agent or any holder of a Note shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Borrower and the Company under Section 15, the Company will pay to the Collateral Agent and to the holder of each Note on demand such further amount as shall be sufficient to cover all reasonable costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

SECTION 13. REGISTRATION; TRANSFER; SUBSTITUTION OF NOTES.

Section 13.1 Registration of Notes. The Borrower shall keep at its principal executive office a register for the registration and registration of transfers of Notes.

Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit A. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. Notes shall not be transferred in denominations of less

than $5,000,000 (or, in the case of any transfer to an existing holder of a Note or an Affiliate thereof, $1,000,000); provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than $5,000,000.

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it, or

the Borrower at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Section 13.4 Securitization. The Borrower hereby acknowledges that the holders of Notes and their permitted transferees may sell or securitize the Obligations (a “Securitization”) owing thereto through the pledge of the Obligations as collateral security for loans to such holders or their permitted transferees or through the sale of the right to payment on the Obligations or the issuance of direct or indirect undivided interests in the Obligations. The Borrower shall cooperate with the holders of Notes to effect any proposed Securitization including, without limitation, by providing such information as may be reasonably requested by the holders in connection with the rating of the Obligations by a nationally recognized ratings agency in connection with the Securitization.

principal executive office or at the place of payment most recently designated by the Borrower pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Borrower in exchange for a new Note or Notes pursuant to Section 13.2. The Borrower will afford the benefits of this Section 14.2 to any Purchaser that is the direct or indirect transferee of any Note purchased by such Purchaser under this Agreement and that has made the same agreement relating to such Note as such Purchaser has made in this Section 14.2.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the other Related Documents, the purchase or transfer by a holder of any Note or Warrant of such Note or Warrant or portion thereof or interest therein and the payment of any Note or the exercise of any Warrant, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of any holder of a Note. All statements contained in any certificate or other instrument delivered by or on

behalf of the Borrower or the Company pursuant to this Agreement shall be deemed representations and warranties of the Borrower or the Company under this Agreement. Subject to the preceding sentence, this Agreement and the other Related Documents embody the entire agreement and understanding between the Purchasers and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.

SECTION 17. AMENDMENT AND WAIVER.

Section 17.1 Requirements. This Agreement and the Notes may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company, the Borrower and the Majority Holders, except that no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (a) change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on, the Notes, (b) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (c) amend any of Sections 8.1, 11(a), 12.1(a) and (b), 17.1 or 20 or the definition of Majority Holders set forth on Schedule B. The Warrants may be amended, and the observance of any term thereof may be waived (either retroactively or prospectively) as provided therein. Notwithstanding the foregoing, the provisions of Section 4.2 and, solely with respect to the Subsequent Closing, Section 4.3, may be amended only with the written consent of the Borrower, the Company and all of the Purchasers obligated to purchase Notes to be issued and sold at the Subsequent Closing, and may be waived by any such Purchaser, but only to the extent applicable to such Purchaser. Notwithstanding the provisions of this Section 17.1 to the contrary, no amendment or modification to this Agreement or the Notes that materially and adversely affects the rights of any Purchaser in a manner disproportionate to other Purchasers shall be effective with respect to such Purchaser or the Notes held by such Purchaser unless such amendment or modification has been approved in writing by the Majority Holders and an additional Purchaser that is not an Affiliate of such approving Majority Holders.

Section 17.2 Solicitation of Holders of Notes.

(a) Solicitation. The Borrower will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Borrower and the Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b) Payment. Neither the Borrower nor the Company will directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver

or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

Section 17.3 Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Borrower without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Borrower and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

Section 17.4 Notes Held by Company, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Subsidiaries shall be deemed not to be outstanding.

Each of the Company and the Borrower agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by a holder of any Note in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company and the Borrower or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

SECTION 20. CONFIDENTIAL INFORMATION.

For the purposes of this Section 20, “Confidential Information” means information delivered to a Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is related to the business or property of the Company or its Subsidiaries or to this Agreement or the other Related Documents; provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser without restriction prior to the time of such disclosure as evidenced by its written records, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on its behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to a holder of a Note under Section 7.1(a) or (b) that are otherwise publicly available, except in the case of clause (a), (b), or (c), to the extent such information came from a source known to such Purchaser to be bound by an obligation of confidentiality to the Company as any of its Subsidiaries. Each Purchaser agrees to maintain the confidentiality of such Confidential Information for a period of at least 7 years in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered thereto, which procedures shall be at least as stringent as those used by such Purchaser with respect to its own important confidential information; provided that a Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by such Purchaser’s Notes) who are bound to the terms of this Section 20 or are otherwise bound by a duty of confidentiality at least as restrictive as the terms of this Section 20, (ii) such Purchaser’s financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Person who is permitted to purchase a Note or Warrant from such Purchaser pursuant to the terms hereof or of

Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20.

SECTION 21. THE COLLATERAL AGENT.

Section 21.1 Appointment; Nature of Relationship. LB I Group Inc. is appointed by the Purchasers as the Collateral Agent hereunder and under each of the other Related Documents, and each of the Purchasers irrevocably authorizes the Collateral Agent (for so long as the Collateral Agent remains in such capacity under this Agreement) to act as the contractual representative of such Purchaser with only the rights and duties expressly set forth herein and in the other Related Documents. The Collateral Agent agrees to act as such contractual representative upon the express conditions contained in this Section 21. Notwithstanding the use of the defined term “Collateral Agent” it is expressly understood and agreed that the Collateral Agent shall not have any fiduciary responsibilities to any Purchaser by reason of this Agreement and that the Collateral Agent is merely acting as the representative of the Purchasers with only those duties as are expressly set forth in this Agreement and the other Related Documents. In its capacity as the Purchasers’ contractual representative, the Collateral Agent (i) does not assume any fiduciary duties to any of the Purchasers, (ii) is a “representative” of the Purchasers within the meaning of Section 9-511 of the UCC and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Related Documents. Each of the Purchasers agrees to assert no claim against the Collateral Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Purchaser waives.

Section 21.2 Powers. The Collateral Agent shall have and may exercise such powers under the Related Documents as are specifically delegated to the Collateral Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Collateral Agent shall have no implied duties or fiduciary duties to the Purchasers, or any obligation to the Purchasers to take any action hereunder or under any of the other Related Documents except any action specifically provided by the Related Documents required to be taken by the Collateral Agent.

Section 21.3 General Immunity. Neither the Collateral Agent nor any of its directors, officers, agents or employees shall be liable to the Company, the Borrower, any Subsidiary or Affiliate of the Company or the Borrower, or any Purchaser for any action taken or omitted to be taken by it or them hereunder or under any other Related Documents or in connection herewith or therewith except to the extent such action or inaction is found in a final judgment by a court of competent jurisdiction to have arisen solely from (i) the gross negligence or willful misconduct of such Person or (ii) breach of contract by such Person with respect to the Related Documents.

Section 21.4 No Responsibility for Loans, Creditworthiness, Collateral, Recitals, Etc. Neither the Collateral Agent nor any of its directors, officers, Collateral Agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (i) any statement, warranty or representation made in connection with any Related Document or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of any obligor under any Related Document; (iii) the satisfaction of any condition specified in Section 4, except receipt of items required to be delivered solely to the Collateral Agent; (iv) the existence or possible existence of any Default or Event of Default or (v) the validity, effectiveness or genuineness of any Related Document or any other instrument or writing furnished in connection therewith. The Collateral Agent shall not be responsible to any Purchaser for any recitals, statements, representations or warranties herein or in any of the other Related Documents, for the perfection or priority of any of the Liens on any of the Collateral, or for the execution, effectiveness, genuineness, validity, legality, enforceability, collectability, or sufficiency of this Agreement or any of the other Related Documents or the transactions contemplated thereby, or for the financial condition of any guarantor of any or all of the Obligations, the Company or any of its Subsidiaries.

Section 21.5 Action on Instructions of Purchasers. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Related Document in accordance with written instructions signed by the Majority Holders (or any other percentage of Purchasers specified to be the applicable percentage in this Agreement or any other Related Document to act on specified matters), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Purchasers and on all holders of Notes. The Collateral Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Related Document unless it shall first be indemnified to its satisfaction by the Purchasers pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

Section 21.6 Employment of Collateral Agents and Counsel. The Collateral Agent may execute any of its duties as the Collateral Agent hereunder and under any other Related Document by or through employees, agents, and attorney-in-fact and shall not be answerable to the Purchasers, except as to money or securities received by it or its authorized agents. The Collateral Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Collateral Agent and the Purchasers and all matters pertaining to the Collateral Agent’s duties hereunder and under any other Related Document.

Section 21.7 Reliance on Documents; Counsel. The Collateral Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Collateral Agent, which counsel may be employees of the Collateral Agent.

Section 21.8 The Collateral Agent’s Reimbursement and Indemnification. The Purchasers agree to reimburse and indemnify the Collateral Agent ratably in proportion to the principal amount of their respective Notes outstanding from time to time (i) for any amounts not reimbursed by the Borrower or the Company for which the Collateral Agent is entitled to reimbursement under the Related Documents, (ii) for any other expenses incurred by the Collateral Agent on behalf of the Purchasers, in connection with the preparation, execution, delivery, administration and enforcement of the Related Documents and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of the Related Documents or any other document delivered in connection therewith or the transactions contemplated thereby, or the enforcement of any of the terms thereof or of any such other documents, provided that no Purchaser shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have arisen solely from the gross negligence or willful misconduct of the Collateral Agent.

Section 21.9 Rights as a Purchaser. With respect to its Notes, the Collateral Agent shall have the same rights and powers hereunder and under any other Related Document as any Purchaser and may exercise the same as though it were not the Collateral Agent, and the term “Purchaser” or “Purchasers” shall, unless the context otherwise indicates, include the Collateral Agent in its individual capacity.

Section 21.10 Successor Collateral Agent. The Collateral Agent may resign at any time by written notice to the Purchasers and the Credit Parties, and the Collateral Agent may be removed at any time with or without cause by written notice received by the Collateral Agent from the Majority Holders. Upon any such resignation or removal, the Majority Holders shall have the right to appoint, on behalf of the Credit Parties and the Purchasers, a successor Collateral Agent. If no successor Collateral Agent shall have been so appointed by the Majority Holders and shall have accepted such appointment within thirty days after the retiring Collateral Agent’s giving notice of resignation, then the retiring Collateral Agent may appoint, on behalf of the Credit Parties and the Purchasers, a successor Collateral Agent. Notwithstanding anything herein to the contrary, so long as no Default has occurred and is continuing, each such successor Collateral Agent shall be subject to approval by the Credit Parties, which approval shall not be unreasonably withheld. Upon the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent, such successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the other Related Documents. After any retiring Collateral Agent’s resignation hereunder as Collateral Agent, the provisions of this Section 21 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Collateral Agent hereunder and under the other Related Documents.

Section 21.11 Collateral Documents.

(a) Each Purchaser authorizes the Collateral Agent to enter into the Collateral Documents to which it is a party and to take all action contemplated by such documents. Each Purchaser agrees that no holder of the Notes (other than the Collateral Agent) shall have the right individually to seek to realize upon the security granted by any Collateral Document, it being understood and agreed that such rights and remedies may be exercised solely by the Collateral Agent for the benefit of the holders of the Notes upon the terms of the Collateral Documents.

(b) In the event that any Collateral is hereafter pledged by any Person as collateral security for the Obligations, the Collateral Agent is hereby authorized to execute and deliver on behalf of the holders of the Notes any Related Documents necessary or appropriate to grant and perfect a Lien on such Collateral in favor of the Collateral Agent on behalf of the holders of the Notes.

(c) The Purchasers hereby authorize the Collateral Agent, at its option and in its discretion, to (y) release any Lien granted to or held by the Collateral Agent upon any Collateral and/or (z) release any guarantor from its obligations under any Guaranty (i) upon the satisfaction of all of the Obligations at any time arising under or in respect of this Agreement or the Related Documents or the transactions contemplated hereby or thereby; (ii) in connection with any transaction permitted by, but only in accordance with, the terms of the applicable Related Document; or (iii) in connection with any transaction approved, authorized or ratified in writing by the Majority Holders, unless such release is required to be approved by all of the Purchasers hereunder. Upon request by the Collateral Agent at any time, the Purchasers will confirm in writing the Collateral Agent’s authority to release particular types or items of Collateral pursuant to this Section 21.11.

(d) Upon any sale or transfer of assets constituting Collateral which is permitted pursuant to the terms of any Related Document, or consented to in writing by the Majority Holders, the Collateral Agent shall (and is hereby irrevocably authorized by the Purchasers to) execute such documents as may be necessary to evidence the release of the Liens granted to the Collateral Agent for the benefit of the holders of the Notes herein or pursuant hereto upon the Collateral that was sold or transferred; provided, however, that (i) the Collateral Agent shall not be required to execute any such document on terms which, in the Collateral Agent’s reasonable opinion, would expose the Collateral Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of the Company or any of its Subsidiaries in respect of) all interests retained by the Company or any of its Subsidiaries, including (without limitation) the proceeds of the sale, all of which shall continue to constitute part of the Collateral.

SECTION 22. MISCELLANEOUS.

Section 22.1 Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. Neither the Borrower nor the Company shall be entitled to assign its rights hereunder without the written consent of each Purchaser and the Collateral Agent.

Section 22.2 Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day.

Section 22.3 Headings. Section headings used in this Agreement are for convenience of reference only and are not a part of this Agreement for any other purpose.

Section 22.4 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 22.5 Construction.

Section 22.6 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument.

The Borrower and the Company further agree, jointly and severally, to defend, protect, indemnify, and hold harmless the Collateral Agent and each and all of the holders of Notes, each of their respective Affiliates and their respective officers, directors, employees, attorneys and agents (collectively, the “Indemnitees”) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel for such Indemnitees in connection with any investigative, administrative or judicial proceeding, whether or not such Indemnitees shall be designated a party thereto), imposed on, incurred by, or asserted against such Indemnitees in any manner relating to or arising out of this Agreement, or any other Related Documents (collectively, the “Indemnified Matters”); provided, however, that neither the Borrower nor the Company shall have any obligation to an Indemnitee hereunder with respect to Indemnified Matters caused by or resulting from (a) a dispute among the Purchasers or a dispute between any Purchaser and the Collateral Agent, or (b) the willful misconduct or gross negligence of such Indemnitee.
