Other than the Assumed Liabilities, the Buyer is not assuming and shall not be liable for any Liabilities of the Sellers.

Section 2.5 Consents to Certain Assignments.

(a) Notwithstanding anything in this Agreement or any Ancillary Agreement to the contrary, this Agreement and the Ancillary Agreements shall not constitute an agreement to transfer or assign any asset, permit, claim or right or any benefit arising thereunder or resulting therefrom if an attempted assignment thereof, without the consent of a third party, would constitute a breach or other contravention under any agreement or Law to which any Seller is a party or by which it is bound, or in any way adversely affect the rights of the Sellers or, upon transfer, the Buyer under such asset, permit, claim or right, unless the applicable provisions of the Bankruptcy Code permits and/or the Sale Order authorizes the assumption and assignment of such asset, permit, claim, or right irrespective of the consent or lack thereof of a third party. If, with respect to any Transferred Asset, such consent is not obtained or such assignment is not attainable pursuant to the Bankruptcy Code or the Sale Order, then such Transferred Asset shall not be transferred hereunder, and, without prejudice to any of the conditions to the obligations of the Buyer as set forth in Section 7.3 hereof, the Closing shall proceed with respect to the remaining Transferred Assets and the Sellers and the Buyer shall each use their commercially

reasonable efforts, and subject to Section 5.17, the Buyer shall cooperate with the Sellers, to obtain any such consent and to resolve the impracticalities of assignment after the Closing; provided that nothing in this Agreement or any Ancillary Agreement shall require any Seller, the Buyer or any of their respective Affiliates to make any payment or initiate any Action (other than Actions for relief from the Bankruptcy Court) to obtain consent to the transfer of any Transferred Asset as contemplated by this Agreement or any Ancillary Agreement.

(b) If (i) notwithstanding the applicable provisions of Sections 363 and 365 of the Bankruptcy Code and the Sale Order and the reasonable best efforts of the Sellers and Buyer, any consent is not obtained prior to Closing and as a result thereof the Buyer shall be prevented by a third party from receiving the rights and benefits with respect to a Transferred Asset intended to be transferred hereunder, (ii) any attempted assignment of a Transferred Asset would adversely affect the rights of the Sellers thereunder so that the Buyer would not in fact receive all the rights and benefits contemplated, (iii) any Transferred Asset is not otherwise capable of sale and/or assignment (after giving effect to the Sale Order and the Bankruptcy Code), then, in each case, the Sellers shall, subject to any approval of the Bankruptcy Court that may be required, at the written request of the Buyer, cooperate with the Buyer in any lawful and commercially reasonable arrangement under which the Buyer would, to the extent practicable, obtain the economic claims, rights and benefits under such asset and assume the economic burdens and obligations with respect thereto in accordance with this Agreement, including by subcontracting, sublicensing or subleasing to the Buyer. Seller Parent shall promptly pay to the Buyer when received all monies received by the Sellers under such Transferred Asset or any claim or right or any benefit arising thereunder and the Buyer shall indemnify, defend, hold harmless and promptly pay the Sellers for all Liabilities of the Sellers associated with such arrangement.

Section 2.6 Contract Designation.

(a) No later than three (3) Business Days following the entry of the Sales Procedures Order, the Sellers shall deliver to the Buyer a true, correct and complete, to the Knowledge of the Sellers, list (the "Executory Contract List") of all Contracts (including for the avoidance of doubt, any insurance policies and binders that are Transferred Assets and any settlement agreements) related to the Transferred Assets and/or the Business or otherwise used, or held for use, in connection with the Transferred Assets and/or the Business (each, an "Executory Contract"). The Executory Contract List shall describe, in reasonable detail, (i) the monetary amounts that must be paid and nonmonetary obligations that otherwise must be satisfied, including pursuant to Section 365(b)(1)(A) and (B) of the Bankruptcy Code, in order for the Buyer to assume the Transferred Contracts pursuant to this Agreement ("Undisputed Cure Claims"), and (ii) in the case of any Designated Contract, a good faith estimate of the applicable Designated Contract Make-Whole Amount for such Contract. The Sellers will use commercially reasonable efforts to provide the Buyer with (i) copies of each such Contract and (ii) information as to the Liabilities under each such Contract sufficient for the Buyer to make a reasonably informed assessment whether to designate such Contracts as Excluded Assets.

(b) Subject to the entry of the Sale Procedures Order and to the terms and provisions thereof, no later than the tenth (10th) Business Day following entry of the Sale Procedures Order, a copy of the Executory Contract List, which shall be in form and substance acceptable to the Buyer, shall be served on all necessary parties. The Executory Contract List

shall identify the Undisputed Cure Claim, if any, associated with each Contract listed therein, shall identify the Buyer, and shall indicate that the Buyer will, if necessary, provide evidence of adequate assurance of future performance at the Sale Hearing. Any counterparty to an Executory Contract included on the Executory Contract List shall have the time period prescribed by the Sale Procedures Order, or, if no such time period is given, a reasonable amount of time prior to the Auction, to object to the Cure Claims listed on the Executory Contract List and to adequate assurance of future performance.

(c) To the extent a counterparty to an Executory Contract objects or otherwise challenges the Undisputed Cure Claims determined by the Sellers and asserts a different monetary amount that must be paid and/or nonmonetary obligations that otherwise must be satisfied, including pursuant to Section 365(b)(1)(A) and (B) of the Bankruptcy Code, in order for the Buyer to assume such Executory Contract pursuant to this Agreement, the difference between the Undisputed Cure Claims determined by the Sellers and such amounts and/or nonmonetary obligations determined by such counterparty shall be referred to as the "Disputed Cure Claims."

(d) At any time at least three (3) Business Days before the date of the Auction (the "Pre-Auction Designation Date"), the Buyer may designate in writing any Executory Contract as a Transferred Contract to be assumed by it pursuant to this Agreement or remove any Executory Contract previously designated by the Buyer as a Transferred Contract; provided, that, with respect to any newly designated Transferred Contracts, the Sellers shall promptly (x) serve notice on the applicable counterparties setting forth the Sellers' intention to assume and assign such Executory Contracts to Buyer (which notice shall include the applicable proposed Cure Claims) and (y) file or otherwise make any necessary motions before the Bankruptcy Court seeking approval of such assumption and assignment. The Sellers shall pay at Closing any Undisputed Cure Claims associated with the assumption of a Transferred Contract (other than a Designated Contract) that is an Executory Contract or such other amount as agreed to by and among the Sellers, the Buyer and the counterparty. The Sellers shall pay any Disputed Cure Claim associated with the assumption of a Transferred Contract (other than a Designated Contract) that is an Executory Contract pursuant to an Order of the Bankruptcy Court or mutual agreement between the Sellers, the Buyer and the counterparty to the applicable Transferred Contract. To the extent any Transferred Contract (other than a Designated Contract) is subject to a Cure Claim, the Sellers shall pay such Cure Claim directly to the applicable counterparty. The Buyer shall pay at Closing any Undisputed Cure Claims associated with the assumption of a Designated Contract or such other amount as agreed to by and among the Sellers, the Buyer and the counterparty to any Designated Contract. The Buyer shall pay any Disputed Cure Claim associated with the assumption of a Designated Contract pursuant to an Order of the Bankruptcy Court or mutual agreement between the Sellers, the Buyer and the counterparty to the applicable Designated Contract. To the extent any Transferred Contract (other than a Designated Contract) is subject to a Cure Claim, the Sellers shall pay such Cure Claim directly to the applicable counterparty. To the extent any Designated Contract is subject to a Cure Claim, the Buyer shall pay such Cure Claim directly to the applicable counterparty. Subject to Section 2.6(e), in no event shall the Buyer be responsible for curing any defaults under the Transferred Contracts arising prior to Closing or, except with respect to any Designated Contract, otherwise satisfying the Cure Claims relating to the Transferred Contracts. Notwithstanding anything contained herein to the contrary, the Buyer shall only assume, and (other than, for the avoidance of doubt,

the payment at Closing of the applicable Designated Contract Make-Whole Amounts) shall only be responsible for, Contracts designated by it as Transferred Contracts.

(e) Buyer shall continue to be entitled to designate in writing any Contract as a Transferred Contract following the Pre-Auction Designation Date but prior to the fifth Business Day prior to the Closing Date (and, in the event of any such designation, the Sellers shall use commercially reasonable efforts to comply with the notice and filing obligations set forth in clauses (x) and (y) of the first sentence of Section 2.6(d)); provided, that, unless otherwise agreed to in writing by and among the Sellers, the Buyer and the applicable counterparty, the Buyer shall pay all Cure Claims associated with the assumption of any Transferred Contract designated as such pursuant to this Section 2.6(e), which payment shall, in the case of any Cure Claim, be made at the Closing and, in the case of any Disputed Cure Claim, pursuant to an Order of the Bankruptcy Court.

Section 2.7 Consideration.

(a) Subject to Section 2.7(b), the aggregate consideration for the sale, assignment, transfer, conveyance and delivery of the Transferred Assets to the Buyer at the Closing shall consist of (x) (collectively, the "Purchase Price"): (i) the Specified DIP Credit Bid Consideration, (ii) the Specified Prepetition Credit Bid Consideration, (iii) the Treximet Consideration, (iv) an amount in cash equal to $5,000,000 (five million dollars) (the "Cash Component"), (v) at the election of the Buyer in the event there is any Positive Product Working Capital, such amount either in cash or Positive Product Working Capital Credit Bid Consideration, or a combination thereof and (vi) the Lockbox Cash Amount, and (y) the assumption at Closing of the Assumed Liabilities; provided, that the Cash Component shall be increased by the excess (if any) of Buyer Taxes paid by Sellers prior to the Closing ("Seller-Paid Buyer Taxes"), over Seller Taxes not paid by Sellers prior to Closing ("Unpaid Seller Taxes"), or reduced (but not below zero) by the excess (if any) of Unpaid Seller Taxes over Seller-Paid Buyer Taxes (as applicable).

(b) In the event the Bankruptcy Court approves a Treximet Sale, the Treximet Consideration shall no longer constitute part of the Purchase Price.

Section 2.8 Determination of the Purchase Price. Not less than five (5) Business Days prior to the anticipated Closing Date, the Sellers shall deliver to the Buyer a written statement setting forth their good faith estimate of the Excess Cash Amount, Net Product Working Capital, Seller-Paid Buyer Taxes, and Unpaid Seller Taxes, together with reasonable supporting evidence (the "Pre-Closing Statement"). The Pre-Closing Statement shall be accompanied by a certificate of the Chief Financial Officer of the Seller Parent certifying that the Pre-Closing Statement (and the estimates set forth therein) have been prepared in accordance with the Accounting Principles and the Reference Statement. The Sellers shall cause their respective Representatives to assist the Buyer and its Representatives in its review of the Pre-Closing Statement and provide any information as may be reasonably requested by the Buyer in order to allow it to review the calculations set forth in the Pre-Closing Statement. The Sellers shall consider in good faith any comments or objections to any amounts set forth on the Pre-Closing Statement that are notified to it by the Buyer at least 2 Business Days prior to the Closing, and, prior to the Closing, the Sellers may make any modification to the Pre-Closing Statement as requested or approved by the

Buyer. If Buyer reasonably believes that the Pre-Closing Statement has not been prepared in good faith by the Sellers in accordance with the Accounting Principles and the Reference Statement, Buyer shall be entitled to seek, and the Sellers shall cooperate in seeking, expedited review by the Bankruptcy Court to determine whether the Pre-Closing Statement has not been prepared in good faith by the Sellers in accordance with the Accounting Principles and the Reference Statement, in which case the Closing shall be delayed until such time as the Bankruptcy Court has made its determination with respect to the Pre-Closing Statement (and, notwithstanding anything to the contrary in this Agreement, the Outside Date shall be extended to account for such delay). The Pre-Closing Statement, as modified by the Sellers as requested or in good faith following (and in accordance with) any determination by the Bankruptcy Court or as approved by the Buyer, and the Excess Cash Amount, Net Product Working Capital, Seller-Paid Buyer Taxes, and Unpaid Seller Taxes amounts, as set forth on the Pre-Closing Statement (as so modified, if applicable) shall be deemed to be final and binding on the Parties for all purposes hereunder.

Section 2.12 Withholding. The Buyer and its Affiliates and Representatives shall be entitled to deduct and withhold from the consideration otherwise payable to the Sellers pursuant to this Agreement such Taxes as may be required to be deducted and withheld from such consideration under the Code or any other applicable provision of U.S. or foreign Tax Law. If Buyer reasonably believes that it is obligated under applicable Law to deduct or withhold any Taxes from the consideration payable to Sellers, it shall notify Seller Parent prior to the date such withholding is required to be made of its intention to withhold, which notice shall include a statement of the amounts it intends to deduct or withhold in respect of making of such payment and the applicable provision of law requiring the Buyer to withhold or deduct, in each case ten (10) days prior to the date such withholding is required to be made (unless a change in applicable Law prevents the Buyer from providing ten (10) days' advance notice, in which case notice shall be provided as soon as possible following the Buyer becoming aware of such change in Law), and shall reasonably cooperate with Seller to reduce or eliminate such deduction or withholding. To the extent that any amounts are so deducted or withheld, such deducted and withheld amounts shall be (a) remitted by the relevant payor to the applicable Governmental Authority and (b) treated for all purposes of this Agreement as having been paid to the Seller in respect of which such deduction and withholding was made, provided that, notwithstanding anything in this Agreement to the contrary, if withholding on the consideration otherwise payable to a Seller results from a present or former connection between the Designated Buyer and the jurisdiction (other than (x) the United States or (y) Ireland, in the case of a Designated Buyer that is organized under the Laws of Ireland (or a resident of Ireland for Tax purposes) purchasing Transferred Assets and/or assuming Assumed Liabilities from a Seller that is organized under the Laws of Ireland (or a resident of Ireland for Tax purposes) imposing such withholding and such withholding could reasonably be avoided by the use of a Designated Buyer in a different jurisdiction, Buyer shall be required to pay such additional amounts as may be necessary in order that the net amount received by Seller after such withholding or deduction shall equal the amount that would have been received if no withholding or deduction had been made.

Section 2.13 Designated Contract Make-Whole Amounts:

(a) At least three (3) Business Days prior to the Closing Date, the Sellers shall deliver to the Buyer a written notice (the “Make-Whole Notice”) setting forth the Sellers’ good faith calculation of the Designated Contract Make-Whole Amount for each Excluded Designated Contract (with respect to each Excluded Designated Contract, the “Estimated Make-Whole Amount”). Buyer shall have two (2) Business Days after receipt of the Make-Whole Notice to

dispute in good faith any Estimated Make-Whole Amount set forth in the Make-Whole Notice by delivering a written notice to the Sellers (a “Dispute Notice”) setting forth in reasonable detail its disagreement with the calculation of such Estimated Make-Whole Amount and Buyer’s calculation of the Designated Contract Make-Whole Amount for such Excluded Designated Contract (the “Closing Make-Whole Payment”); provided that if Buyer does not timely deliver a Dispute Notice with respect to any Estimated Make-Whole Amount such Estimated Make-whole Amount shall be deemed to be the Closing Make-Whole Payment for such Excluded Designated Contract.

(b) At the Closing, Buyer shall deliver to the Sellers an amount in cash equal to the Closing Make-Whole Payment for each Excluded Designated Contract by wire transfer of immediately available funds to a bank account or bank accounts designated in writing by Seller Parent to the Buyer at least two (2) Business Days prior to the Closing Date.

(c) If the Estimated Make-Whole Amount for any Excluded Designated Contract does not equal the Closing Make-Whole Payment for such Excluded Designated Contract (each, a “Disputed Make-Whole Amount”), the Parties shall submit each such Disputed Make-Whole Amount for resolution to a nationally recognized certified public accounting firm as may be mutually selected by Buyer and Seller Parent (such firm, the “Auditor”). Seller Parent and Buyer shall promptly provide their assertions regarding each unresolved Disputed Make-Whole Amount in writing to the Auditor and each other. The Auditor shall be instructed to render its determination with respect to each Disputed Make-Whole Amount as soon as reasonably possible (which the Parties agree shall be no later than 20 days following the date on which the Disputes are referred to the Auditor). The Auditor shall base its determination solely on (i) the written submissions of the Parties and shall not conduct an independent investigation and (ii) the extent (if any) to which each Disputed Make-Whole Amount requires adjustment in order to be determined in accordance with the definition of Designated Contract Make-Whole Amount (including the definitions of the defined terms used therein). The Auditor shall not assign a value to any Disputed Make-Whole Payment submitted to the Auditor that is greater than the Estimated Make-Whole Payment or less than the Closing Make-Whole Payment for the applicable Excluded Designated Contract. The determination of the Auditor shall be final, conclusive and binding on the Parties. The Designated Contract Make-Whole Amount for any Excluded Designated Contract, as determined by the Auditor pursuant to this Section 2.13(c), is referred to herein as the “Final Make-Whole Amount” for such Excluded Designated Contract. If the Final Make-Whole Amount for any Excluded Designated Contract exceeds the Closing Make-Whole Payment for such Excluded Designated Contract (a “Make-Whole Surplus”), the Buyer shall promptly (and in any event within two (2) Business Days) deliver to the Sellers an amount in cash equal to such Make-Whole Surplus by wire transfer of immediately available funds to a bank account or bank accounts designated in writing by Seller Parent. All fees and expenses of the Auditor relating to the work, if any, to be performed by the Auditor hereunder with respect to any Disputed Make-Whole Amount shall be borne between Buyer, on the one hand, and the Sellers, on the other hand, based upon a fraction, the numerator of which is the portion of the difference between the Estimated Make-Whole Amount and Closing Make-Whole Payment of the applicable Excluded Designated Contract not awarded to the applicable party and the denominator of which is the difference between the Estimated Make-Whole Amount and Closing Make-Whole Payment of the applicable Excluded Designated Contract. For example, if the Estimated Make-Whole Amount for an Excluded Designated Contract is $1,000,000, and the

Closing Make-Whole Payment for such Excluded Designated Contract is $500,000, and the Auditor determines that the Final Make-Whole Amount is $600,000, the Sellers shall bear 80% of the fees and expenses of the Auditor and Buyer shall bear 20% of the fees and expenses of the Auditor.

Each Business Employee who accepts an offer of employment made pursuant to this Section 5.4 and who becomes an active employee of the Buyer or of one of its Affiliates shall be a "Transferred

Employee." The Sellers shall reasonably cooperate with the Buyer in effecting the Transferred Employees' transfer of employment from the Sellers to the Buyer or an Affiliate of the Buyer as contemplated hereby. Each offer of employment made pursuant to this Section 5.4 shall be contingent upon the Closing and the issuance of the Sale Order.

(c) Through and after the Closing Date, each Seller shall comply with its WARN Act obligations, if any. To the extent that any actions taken by Seller pursuant to this Section 5.4 trigger WARN Act obligations with respect to Business Employees who do not become Transferred Employees, Sellers shall be wholly responsible for such obligations.

(d) As promptly as practicable (but no later than 30 days) after the date hereof, Buyer and Sellers shall cooperate in good faith to (i) identify which Employee Plans shall be the Assumed Plans, together with any funding arrangements relating thereto (including but not limited to all assets, trusts, insurance policies and administration service contracts related thereto) to the extent relating to Transferred Employees and (ii) to effect the transfer of such Assumed Plans and funding arrangements related thereto effective as of the Closing.

(e) The Buyer shall pay all unpaid wages and salaries, in respect of Transferred Employees, which are earned or accrued during the payroll period in which the Closing Date occurs.

(g) The Sellers and the Buyer may determine to seek Bankruptcy Court authorization to implement an employee incentive plan, in a mutually agreed upon form (which form shall be agreed by each of the Parties in their sole discretion) (the "Employee Incentive Plan").

(h) To the extent permitted by Law, all unused vacation and paid time off of the Transferred Employees accrued as of the Closing Date shall, effective as of the Closing Date or, if later, the date on which such Transferred Employee becomes an employee of the Buyer, be transferred to and assumed by the Buyer and the Buyer shall honor such accrued vacation on the same basis as under the Sellers' vacation policy as in effect immediately prior to the Closing.

(k) For purposes of each Buyer Plan providing medical, dental, hospital, pharmaceutical or vision benefits to any Transferred Employee, the Buyer shall use reasonable best efforts to cause to be waived all pre-existing condition exclusions and actively-at-work requirements of such Buyer Plan for such Transferred Employee and his or her covered dependents (unless such exclusions or requirements were applicable under Sellers Plans). In addition, the Buyer shall use reasonable best efforts to cause any co-payments, deductible and other eligible expenses incurred by such Transferred Employee and/or his or her covered dependents under any Sellers Plan providing, medical, dental, hospital, pharmaceutical or vision benefits during the plan year during which the Closing Date occurs to be credited for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Transferred Employee and his or her covered dependents for the applicable plan year of each comparable Buyer Plan in which he or she participates.

(l) As soon as practicable following the Closing Date, with respect to the Employee Plans that are tax-qualified defined contribution plans, the Buyer shall permit the Transferred Employees to roll over their account balances and outstanding loan balances, if any, thereunder into an "eligible retirement plan" within the meaning of Section 402(c)(8)(B) of the Code maintained by the Buyer or an Affiliate.

(n) The provisions of this Section 5.4 are for the sole benefit of the Parties to this Agreement only and shall not be construed to grant any rights, as a third party beneficiary or otherwise, to any person who is not a Party to this Agreement, nor shall any provision of this Agreement be deemed to be the adoption of, or an amendment to, any employee benefit plan, as that term is defined in Section 3(3) of ERISA, or otherwise to limit the right of the Buyer or Sellers to amend, modify or terminate any such employee benefit plan. In addition, nothing contained herein shall be construed to (i) prohibit any amendments to or termination of any

employee benefit plans or (ii) prohibit the termination or change in terms of employment of any employee (including any Transferred Employee) as permitted under applicable Law. Nothing herein, expressed or implied, shall confer upon any employee (including any Transferred Employee) any rights or remedies (including, without limitation, any right to employment or continued employment for any specified period) of any nature or kind whatsoever, under or by reason of any provision of this Agreement.

Section 5.5 Consents and Filings; Further Assurances.

The Parties will coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other Parties may reasonably request in connection with the foregoing and in seeking early termination of any applicable waiting or similar periods under applicable Law.

The cost of transition services (including the post-Closing costs during the transition period of maintaining the Leases that would have been rejected but for the Buyer's intention to use the facilities related to such Leases to conduct transition services) shall be borne by the Buyer (and shall include a reasonable and customary administrative markup).
