AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of December 10, 2015, is made by and among Crealta Holdings LLC, a Delaware limited liability company (the “Company”), Horizon Pharma USA, Inc., a Delaware corporation (“[…***…]”), HZNP Limited, a private company limited by shares organized under the laws of Ireland (the “Purchaser,” and together with […***…], the “Purchasers”), Criostail LLC, a Delaware limited liability company and wholly owned subsidiary of the Purchaser (the “Merger Sub”), […***…], and GTCR Fund X/B LP, a Delaware limited partnership, solely in its capacity as representative (the “Representative”) for […***…] and the Company’s Unitholders and Optionholders (all of whom are listed on the attached Sellers Schedule, collectively, the “Sellers”). Capitalized terms used and not otherwise defined herein have the meanings set forth in Article XI below.

WHEREAS, the Purchasers desire to acquire 100% of the membership interests of the Company through […***…] a reverse subsidiary merger transaction pursuant to which the Merger Sub will merge with and into the Company, with the Company surviving as a wholly owned subsidiary of the Purchaser […***…], on the terms and subject to the conditions set forth herein (the “Merger” and, together with the Stock Purchase, the “Transaction”);

WHEREAS, the respective boards of directors or managers (or the equivalent governing bodies) of the Purchasers, the Merger Sub, […***…] and the Company have approved this Agreement, the Merger and/or the Stock Purchase (as applicable) and the related transactions contemplated hereby, upon the terms and subject to the conditions set forth herein; and

WHEREAS, concurrent with the execution and delivery of this Agreement, as a material inducement to Purchasers’ and Merger Sub’s willingness to enter into this Agreement, each Seller listed on Schedule A has executed and delivered to the Purchaser a Joinder Agreement.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

THE MERGER AND THE STOCK PURCHASE

1.01 The Merger.

(a) Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, the Merger Sub shall merge with and into the Company in accordance with the Delaware Limited Liability Company Act (as amended, “Delaware LLC Law”),

***Confidential Treatment Requested

whereupon the separate existence of the Merger Sub shall cease and the Company shall be the surviving limited liability company (the “Surviving Company”) and a wholly owned subsidiary of the Purchaser […***…].

(b) At the Closing, the Company and the Merger Sub shall cause a certificate of merger substantially in the form of Exhibit A hereto (the “Certificate of Merger”) to be executed, acknowledged and filed with the Secretary of State of the State of Delaware and shall make all other filings or recordings required by Delaware LLC Law in connection with the Merger. The Merger shall become effective at such time (the “Effective Time”) as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware in accordance with the Delaware LLC Law or at such later time as the Purchaser and the Company mutually agree and specify in the Certificate of Merger.

(c) From and after the Effective Time, the Surviving Company shall succeed to all the assets, rights, privileges, powers and franchises and be subject to all of the liabilities, restrictions, disabilities and duties of the Company and the Merger Sub, all as provided under Delaware LLC Law.

1.02 Conversion of Units.

At the Effective Time, by virtue of the Merger and without any action on the part of any party:

(a) Each Unit (and the membership interests represented thereby) issued and outstanding immediately prior to the Effective Time (other than (i) any Units (and the membership interests represented thereby) which are held by any wholly owned Subsidiary of the Company or in the treasury of the Company or by the Purchasers or the Merger Sub, all of which shall cease to be outstanding and be canceled for no consideration and none of which shall receive any payment with respect thereto, and (ii) any Units (and the membership interests represented thereby) which are held by […***…], all of which shall be cancelled for no consideration and converted, without […***…] receiving any payment with respect thereto, into membership interests in the Surviving Company with a fair market value equal to the fair market value of such Units held by […***…], as such membership interests are provided for by the Surviving Company LLC Agreement) and all rights in respect thereof shall, by virtue of the Merger and without any action on the part of the holder thereof, shall cease to exist and shall be converted into and represent solely the right to receive an amount in cash, without interest, equal to (A) the Allocable Portion of the Closing Merger Consideration attributable to such Unit less the portion of the Representative Holdback Amount attributable to such Unit, plus (B) any Additional Merger Consideration attributable to each such Unit (as set forth in the Closing Payment Schedule), plus (C) any Escrow Distribution attributable to such Unit (as set forth in the Closing Payment Schedule). No further transfer of any Units shall be made on the Unit Ownership Ledger after the Effective Time. If, after the Effective Time, a valid certificate previously representing any Units is presented to the Surviving Company, the Purchaser or the Paying Agent (in accordance with Section 1.04), such certificate shall be cancelled and shall be exchanged as provided in this Section 1.02.

***Confidential Treatment Requested

(b) Each membership interest of the Merger Sub (a “Merger Sub Interest”) issued and outstanding immediately prior to the Effective Time shall be converted into membership interests in the Surviving Company, as such common units are provided for by the Surviving Company LLC Agreement. As of the Effective Time, the Merger Sub Interests shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and the holder or holders of such membership interests shall cease to have any rights with respect thereto, except the right to receive membership interests in the Surviving Company to be issued in consideration therefor as provided herein, without interest. As of the Effective Time, the Purchaser and […***…] shall be the holders of all the issued and outstanding units of the Surviving Company.

1.03 Merger Consideration.

(a) At least […***…] Business Days prior to the Closing Date, the Company shall prepare and deliver to the Purchaser a written statement, signed by the Company’s Chief Financial Officer (the “Pre-Closing Statement”), containing its good faith calculation of its estimate of (i) Closing Date Cash (the “Estimated Cash”), (ii) Closing Date Indebtedness (the “Estimated Indebtedness”), (iii) Net Working Capital (the “Estimated Net Working Capital Amount”), and (iv) Transaction Expenses (the “Estimated Transaction Expenses”). During the period beginning on the date of delivery of the Pre-Closing Statement by the Company until the Closing Date, as reasonably requested by the Purchaser, the Company shall consult with the Purchaser (including by giving the Purchaser an opportunity to provide comments to the Pre-Closing Statement), shall work in good faith to resolve any differences the Company and the Purchaser may have with respect to any of the amounts or calculations set forth in the Pre-Closing Statement, and the Company will make available to the Purchaser and its representatives the work papers and other books and records used in preparing the Pre-Closing Statement and afford the Purchaser and its representatives reasonable access to the relevant personnel and its external representatives of the Company to verify the accuracy of such amounts to the extent deemed reasonably necessary by the Purchaser.

(b) Prior to the Closing Date, the Company shall prepare and deliver to the Purchaser a spreadsheet (the “Closing Payment Schedule”), duly certified by the Chief Financial Officer of the Company setting forth:

(i) the calculation of the Closing Merger Consideration;

(ii) with respect to each holder of Units immediately prior to the Effective Time: (A) the name of such holder, (B) whether such holder is a current or former employee of the Company or any of its Subsidiaries, (C) the total number of Units held by such holder as of immediately prior to the Effective Time, with separate indication of the number of Allocated Units and the number of Unallocated Units (D) the portion of the Closing Merger Consideration that such holder is entitled to receive in respect of such Units pursuant to Section 1.02(a), with separate indication of the Closing Merger Consideration attributable to Allocated Units and Unallocated Units, (E) the portion of such holder’s proceeds referenced in the preceding clause (D) that are to be delivered by the Purchasers to the Representative to fund the Representative Holdback Amount under Section 1.08, with separate indication of the portion attributable to

(iii) with respect to each holder of Options immediately prior to the Effective Time: (A) the name of such Optionholder, (B) whether such holder is an employee of the Company or any of its Subsidiaries, (C) the number of Units underlying such Option immediately prior to the Effective Time, (D) the portion of the Closing Merger Consideration that such holder is entitled to receive in respect of such Options pursuant to Section 1.05, (E) the portion of such holder’s proceeds referenced in the preceding clause (D) that are to be delivered by the Purchaser to the Representative to fund the Representative Holdback Amount under Section 1.08, (F) such holder’s Residual Percentage and (G) whether any Taxes are required to be withheld from any portion of the consideration payable to such holder in respect of such Options on account of the performance of services; and

(iv) […***…]

(c) The calculations of Estimated Cash, Estimated Indebtedness, Estimated Net Working Capital and Estimated Transaction Expenses on the Pre-Closing Statement will be prepared and will be determined, on a consolidated basis, in accordance with the terms of Section 2.01 regarding the preparation of the Preliminary Statement.

(d) For purposes of this Agreement, the term “Closing Merger Consideration” means (i) $510,000,000 (the “Base Consideration”), minus (ii) the amount of the Estimated Indebtedness, plus (iii) the amount, if any, by which the Estimated Net Working Capital Amount exceeds the Target Net Working Capital Amount, minus (iv) the amount, if any, by which the Target Net Working Capital Amount exceeds the Estimated Net Working Capital Amount, plus (v) the amount of Estimated Cash, minus (vi) the Escrow Amount, minus (vii) the amount of the Estimated Transaction Expenses, plus (viii) the aggregate exercise price of the Options that are outstanding immediately prior to the Effective Time.

***Confidential Treatment Requested

Working Capital as finally determined pursuant to Article II, plus (v) the amount of Closing Date Cash as finally determined pursuant to Article II, minus (vi) the Escrow Amount, minus (vii) the amount of Transaction Expenses as finally determined pursuant to Article II, plus (viii) the aggregate exercise price of the Options that are outstanding immediately prior to the Effective Time.

1.04 Unit Exchange.

(a) The Purchaser shall cause a paying agent appointed by the Purchaser, and reasonably acceptable to the Representative (the “Paying Agent”), to effect the exchange of cash for the Units which are entitled to payment pursuant to Section 1.02. After the Effective Time, each Unitholder who has surrendered his, her or its Units (together with a certificate or certificates that immediately prior to the Effective Time represented such Units) pursuant to a duly executed and completed letter of transmittal, substantially in the form of Exhibit B attached hereto (each, a “Letter of Transmittal”), to the Paying Agent, shall be entitled to receive from the Paying Agent in exchange therefor the portion of the Closing Merger Consideration into which such Unitholder’s Units shall have been converted as a result of the Merger (less the portion of the Representative Holdback Amount attributable to such Units) as determined pursuant to Section 1.02 (it being agreed that any Unitholder that delivers a duly executed and completed Letter of Transmittal to the Paying Agent in accordance with this Section 1.04 at least […***…] Business Days prior to the Closing shall be paid such consideration by the Paying Agent as promptly as reasonably practicable and, in any event, within […***…] Business Days of the Closing) and thereafter, as, when and if any Additional Merger Consideration and/or Escrow Distribution is payable in accordance with the terms of this Agreement, such Unitholder shall be entitled to be paid the Additional Merger Consideration and/or Escrow Distribution into which such Unitholder’s Units shall have been converted as a result of the Merger as determined pursuant to Section 1.02. Notwithstanding the foregoing, the Closing Merger Consideration with respect to Unallocated Units (less the portion of the Representative Holdback Amount attributable to such Units) that is payable to holders who are not partners of the Company for U.S. federal income Tax purposes prior to the date of this Agreement shall be paid through the payroll system of the Surviving Company and/or its Subsidiaries in accordance with Section 3.02(d). Until so surrendered and exchanged, each Unit shall represent solely the right to receive the Allocable Portion of the Closing Merger Consideration attributable to such Unit (less the portion of the Representative Holdback Amount attributable to such Unit), and any Additional Merger Consideration and/or Escrow Distribution into which it was converted pursuant to Section 1.02. Notwithstanding the foregoing, if any certificate representing such Units shall have been lost, stolen or destroyed, then, upon the making of an affidavit of such fact by the Person claiming such certificate to be lost, stolen or destroyed (which may include an indemnity or bond in customary form), the Paying Agent and/or the Surviving Company, as applicable, shall issue, in exchange for such lost, stolen or destroyed certificate, the Allocable Portion of the Closing Merger Consideration (less the applicable portion of the Representative Holdback Amount) and any Additional Merger Consideration and/or Escrow Distribution to be paid in respect of the Units represented by such certificate, as contemplated by this Article I.

(b) Any amount remaining with the Paying Agent after the […***…] anniversary of the Closing Date may, at the Purchaser’s request, be remitted to the Surviving Company and thereafter any Unitholder shall direct any claims for payment hereunder to the

***Confidential Treatment Requested

Surviving Company as a general creditor thereof. Any such amounts remaining unclaimed by any Unitholder immediately prior to such time when such amounts would otherwise escheat to or become the property of any Governmental Entity, shall, to the extent permitted by applicable Laws, become the property of the Purchaser, free and clear of all claims or interest of any Person previously entitled thereto. Notwithstanding anything to the contrary in this Section 1.04, none of the Paying Agent, the Purchaser, the Surviving Company or any party hereto shall be liable for any amount properly paid to a public official in compliance with any applicable abandoned property, escheat or similar Law.

1.05 Options. The Company shall, as of the Effective Time, cause all Options, whether or not then vested or exercisable, to be canceled and extinguished, no longer be outstanding and cease to represent the right to acquire Units, and in consideration therefor, the Optionholders shall be entitled to receive with respect to each Option: (i) reasonably promptly following the Effective Time an amount in cash, without interest and subject to withholding pursuant to Section 3.03 below, equal to the product of (A) the excess, if any, of the Allocable Portion of the Closing Merger Consideration attributable to each Unit that is subject to such Option over the exercise price per Unit payable upon exercise of such Option, multiplied by (B) the number of Units that would be issued upon exercise of such Option if such holder had exercised such Option in full immediately prior to the Effective Time (the “Closing Option Consideration”), plus (ii) any Additional Merger Consideration attributable to the Common Units underlying such Option to the extent payable in accordance with the terms of this Agreement (as set forth in the Closing Payment Schedule), plus (iii) any Escrow Distribution attributable to the Common Units underlying such Option to the extent payable in accordance with the terms of this Agreement (as set forth in the Closing Payment Schedule).

1.06 Organizational Documents of the Surviving Company.

(a) At the Effective Time and without any further action on the part of the Company or the Merger Sub, the certificate of formation of the Company, as in effect immediately prior to the Effective Time, shall be the certificate of formation of the Surviving Company as of the Effective Time, until duly amended in accordance with applicable Law.

(b) At the Effective Time and without any further action on the part of the Company or the Merger Sub, the limited liability company agreement of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated to read in its entirety as provided by Exhibit C and, commencing as of the Effective Time, shall be the limited liability company agreement of the Surviving Company (the “Surviving Company LLC Agreement”), until thereafter amended as provided therein and by applicable Law.

1.07 Directors and Officers of the Surviving Company.

(a) At the Effective Time, the Company’s board of managers shall resign and the managers of the Merger Sub immediately prior to the Effective Time shall become the managers of the Surviving Company and shall hold office subject to the applicable provisions of the Surviving Company LLC Agreement.

(b) At the Effective Time, the officers of the Merger Sub immediately prior to the Effective Time shall be the officers of the Surviving Company and shall hold office subject to the applicable provisions of the Surviving Company LLC Agreement.

1.08 Representative Holdback. A portion of the proceeds otherwise to be received by the Sellers pursuant to Article I in an aggregate amount equal to $[…***…] (such initial deposit, as it may be decreased at any time in accordance with this Agreement, the “Representative Holdback Amount”) shall be delivered by the Purchasers to the Representative at the Closing, on behalf of the Sellers, by wire transfer of immediately available funds to a segregated account designated by the Representative (which account shall be used only to hold the Representative Holdback Amount and to pay any payments, fees, costs and expenses of the Representative payable by the Representative pursuant to the terms of this Agreement). The portion of the Representative Holdback Amount delivered to, and held by, the Representative on behalf of each such Seller shall be determined pro rata based upon each Seller’s Residual Percentage. The Representative is entitled to pay on behalf of the Sellers, and to the extent paid by the Representative from its own funds, obtain reimbursement for, any reasonable out-of-pocket fees, costs and expenses incurred by the Representative in the performance of its duties hereunder (“Representative Expenses”) from the Representative Holdback Amount, and the Representative shall not use any portion of the Representative Holdback Amount for any other purpose. For all purposes of this Agreement, any and all amounts paid by the Purchasers to the Representative pursuant to this Section 1.08 or otherwise in respect of the Representative Holdback Amount shall be deemed to have been paid to the Sellers and in no event shall the Purchasers or any of their Affiliates have any further obligation or Liability to any Seller in respect thereof. For the avoidance of doubt, any amounts paid by the Purchasers to the Representative in respect of the Representative Holdback Amount shall be treated for Tax purposes as having been received and voluntarily set aside by the Sellers at the time of payment by the Purchasers, and any Tax withholding with respect to such deemed contribution by any Seller shall be satisfied from such Seller’s share of other funds payable to such Seller at such time and shall not reduce the Representative Holdback Amount.

1.09 No Dissenter’s Rights or Appraisal Rights. No holder of Units or Options shall be entitled to any “dissenter’s rights,” “appraisal rights” or any similar remedies under Delaware LLC Law or any other applicable Law. Following the Effective Time, each holder of any Units and/or Options shall be entitled only to the right to receive the appropriate portion of the Closing Merger Consideration, the Additional Merger Consideration (if any) and the Escrow Distribution (if any) payable in respect of such Units and/or Options, as applicable, pursuant to the terms and conditions of this Agreement.

1.10 Stock Purchase.

(a) Sale and Purchase of Shares. At the Closing, upon the terms and subject to the conditions set forth in this Agreement, […***…] agrees to sell, assign, transfer and deliver to […***…], free and clear of any Liens (other than those imposed by federal or state securities laws), and […***…] agrees that it shall purchase and accept delivery from […***…] of, the Shares, free and clear of any Liens (other than those imposed by federal or state securities laws).

***Confidential Treatment Requested

(b) Consideration. At the Closing, […***…] shall cause the Paying Agent to deliver to […***…], as consideration for the Shares, an aggregate amount equal to the Allocable Portion of the Closing Merger Consideration attributable to the Units […***…] (assuming for purposes of calculating such amount that such Units are outstanding at the Effective Time). Additionally, to the extent the Sellers are entitled to receive any Additional Merger Consideration and/or Escrow Distribution, then […***…] shall be entitled to receive, as consideration for the Shares, […***…] Residual Percentage of such Additional Merger Consideration and/or Escrow Distribution in accordance with the terms of this Agreement.

ARTICLE II

MERGER CONSIDERATION ADJUSTMENT

2.01 Final Closing Balance Sheet Calculation. As promptly as possible, but in any event within […***…] days after the Closing Date, the Purchasers will deliver to the Representative unaudited consolidated balance sheets of […***…] and of the Company and its Subsidiaries as of immediately prior to the Closing (the “Closing Balance Sheets”) and a statement showing the calculation of Closing Date Cash, Closing Date Indebtedness and Net Working Capital derived from the Closing Balance Sheets and the Transaction Expenses (together with the Closing Balance Sheets, the “Preliminary Statement”). The calculation of Net Working Capital in the Preliminary Statement shall be prepared in accordance with (i) GAAP, and shall not include any changes in assets or liabilities as a result of purchase accounting adjustments or other changes arising from or resulting as a consequence of the transactions contemplated hereby and (ii) to the extent not inconsistent with clause (i), the accounting methods, policies, categorizations, definitions, principles, assets recognition bases, practices, techniques and procedures (including in respect of management’s exercise of judgment) adopted in connection with the latest balance sheet included in the Audited Financial Statements. The parties agree that the purpose of preparing the Closing Balance Sheets and determining Closing Date Cash, Closing Date Indebtedness and Net Working Capital and the related purchase price adjustment contemplated by this Section 2.01 is to (A) measure the amount of Closing Date Cash and Closing Date Indebtedness and (B) measure changes in Net Working Capital against the Target Net Working Capital Amount, and such processes are not intended to permit the introduction of different judgments, accounting methods, policies, principles, practices, procedures, classifications or estimation methodologies for the purpose of preparing the Closing Balance Sheets or determining Closing Date Cash, Closing Date Indebtedness or Net Working Capital; provided, in each case, that the judgments, accounting methods, policies, principles, practices, procedures, classifications and estimation methodologies used in preparing the Pre-Closing Statement and determining Estimated Cash, Estimated Indebtedness and Estimated Net Working Capital were consistent with the requirements set forth in clauses “(i)” and “(ii)” above. The Representative and its accountants and other representatives shall be permitted reasonable access during normal business hours upon reasonable advance notice to review […***…] the Company’s and its Subsidiaries’ books and records and any work papers related to the preparation of the Preliminary Statement and the adjustments contemplated hereby; provided, that such access does not unreasonably interfere with the business operations of the Purchasers, the Surviving Company or any of their respective Affiliates and that the Persons

***Confidential Treatment Requested

provided such access shall treat any confidential or proprietary information of […***…] the Surviving Company or any of their respective Subsidiaries received in connection therewith as confidential and shall not disclose such information to any third party. The Representative and its accountants and other representatives may make reasonable inquires of the Purchasers, the Surviving Company and their respective accountants regarding questions or disagreements, and the Purchasers shall use their, and shall cause the Surviving Company and its Subsidiaries to use their, commercially reasonable efforts to cause any such accountants to reasonably cooperate with and respond to such inquiries.

ARTICLE XII

MISCELLANEOUS

12.01 Survival of Representations, Warranties, Covenants and Agreements. The representations and warranties of the Company contained in Article V of this Agreement or in any certificate delivered to Parent or Merger Sub by or on behalf of the Company in connection herewith and the covenants and agreements contained in this Agreement that are to be performed by the Company prior to Closing (the “Pre-Closing Covenants”) shall survive until the termination of […***…]; provided, that (a) the Tax Representations shall survive until the date that is […***…] days after the applicable statute of limitations for the subject matter of such representations and warranties expires and (b) the Fundamental Representations shall survive until 11:59 p.m. Pacific Time on the date that is […***…] following the Closing Date; provided, further, that any claim that is properly asserted in writing pursuant to this Article XII prior to the expiration of the survival period applicable to such representation or warranty set forth above shall survive until such claim is finally resolved and satisfied. Except for Section 6.10, the representations and warranties of the Purchasers and Merger Sub contained in this Agreement or in any certificate delivered pursuant to this Agreement shall terminate […***…]. All covenants and other agreements contained in this Agreement other than the Pre-Closing Covenants shall survive […***…] in accordance with their respective terms. It is the express intent of the parties hereto that, if the applicable survival period for an item as contemplated by this Section 12.01 is shorter or longer than the statute of limitations that would otherwise have been applicable to such item, then, by contract, the applicable statute of limitations with respect to such item shall be reduced or extended, as applicable, to the shortened or extended survival period contemplated hereby, as the case may be. The parties hereto acknowledge that the time periods set forth in this Section 12.01 for the assertion of claims under this Agreement are the result of arms’-length negotiation among the parties and that they intend for the time periods to be enforced as agreed by the parties.

12.02 Indemnification by the Sellers. Subject to the other provisions of this Article XII and the Escrow Agreement, following the Closing, each Seller shall, severally and not jointly, in accordance with such Seller’s Residual Percentage, indemnify the Purchasers and the Surviving Company, their respective Affiliates, and each of their respective officers, directors, employees, stockholders, agents, other representatives, successors and permitted assigns (each a “Purchaser Indemnified Party”) in respect of, and hold them harmless against, any Damages suffered, incurred or sustained by any Purchaser Indemnified Party resulting from or arising out of:

(a) any inaccuracy in or breach, as of the date of this Agreement and/or as of the Effective Time (as if such representation or warranty had been made as of the Effective Time), of any representation or warranty made by the Company in Article V of this Agreement or in any certificate delivered to Parent or Merger Sub by or on behalf of the Company in connection herewith;

***Confidential Treatment Requested

(b) any breach or nonfulfillment by any member of the Company Group, […***…] or the Representative of any of their respective covenants, obligations or agreements contained in this Agreement;

(c) regardless of the disclosure of any matter set forth in the Disclosure Schedules, the allocation or misallocation of the Closing Merger Consideration, the Additional Merger Consideration and/or Escrow Distributions amongst the Sellers, including as a result of any inaccuracy or error in the Closing Payment Schedule;

(d) any claim by a current or former holder of Units, Options or Shares or any other Person, seeking to assert, or based upon: (i) ownership or rights to ownership of any shares of capital stock, membership interests or other equity securities of any member of the Company Group, including any claims for breaches of fiduciary duties owed to such Person in such capacity; or (ii) any rights of a stockholder or other equity holder (other than in the case of clauses “(i)” and “(ii)” claims based on the rights of any such Person to receive a portion of the payments contemplated to be made to such Person hereby as and to the extent set forth herein), including any option, preemptive rights or rights to notice or to vote;

(e) any Closing Date Indebtedness or Transaction Expenses in each case, to the extent not taken into account in the calculation of the Final Merger Consideration in accordance with Article II;

(f) regardless of the disclosure of any matter set forth in the Disclosure Schedules, any Indemnified Taxes; and/or

(g) the Splitter LP Liquidation.

12.03 Indemnification Limitations

(a) Except in the case of fraud and claims under Section 9.03, (i) this Article XII shall be the exclusive means for any Purchaser Indemnified Party to collect any Damages for which it is entitled to indemnification under this Agreement and (ii) the Purchaser Indemnified Parties’ sole and exclusive source of recovery for indemnification claims under Section 12.02(a) […***…]; provided, that in no event shall any Seller’s aggregate Liability to the Purchaser Indemnified Parties for indemnification claims pursuant to this Article XII and Section 9.03 exceed […***…]. The parties acknowledge that there shall not be any duplicative recovery for any Damages arising from the same facts and circumstances.

(b) Notwithstanding anything to the contrary contained in this Agreement, no Purchaser Indemnified Party shall be entitled to recover any Damages related to any particular claim for indemnification under Section 12.02(a), unless and until the amount of such Damage

***Confidential Treatment Requested

for which it would otherwise be entitled to indemnification under Section 12.02(a) exceeds $[…***…] (the “Per Claim Deductible”) (it being understood and agreed that (i) any claim for an amount of less than the Per Claim Deductible shall be disregarded in determining whether the Indemnity Deductible has been exceeded and (ii) any Damage or Damages resulting from any single claim or series of related claims arising out of or resulting from the same facts, events, or circumstances shall be deemed to be one and the same claim for these purposes and shall be aggregated in determining whether the Per Claim Deductible was exceeded); provided, that the Per Claim Deductible shall not apply to (i) any claims for fraud or (ii) any Damages related to the inaccuracy in or breach of any of the Fundamental Representations or the Tax Representations.

(c) Notwithstanding anything to the contrary contained in this Agreement, no Purchaser Indemnified Party shall be entitled to recover any Damages under Section 12.02(a) unless and until the aggregate Damages in excess of the Per Claim Deductible for which they would otherwise be entitled to indemnification under Section 12.02(a) exceed $[…***…] (the “Indemnity Deductible”) (at which point the Purchaser Indemnified Parties shall become entitled to be indemnified only for such Damages in excess of the Indemnity Deductible); provided, that the Indemnity Deductible shall not apply to (i) any claims for fraud or (ii) any Damages related to the inaccuracy in or breach of any of the Fundamental Representations or the Tax Representations.

(d) For purposes of Section 12.02(a), a breach shall be determined without regard to any qualification based on materiality, Material Adverse Effect or similar qualifier contained in such representation or warranty (or in any defined term contained in such representation or warranty other than the first sentence of Section 5.06 and the definition of “Material Adverse Effect” in Article XI. Additionally, a Purchaser Indemnified Party’s entitlement to indemnification pursuant to this Agreement will not be affected by any examination made for or on behalf of any of such parties or the knowledge of any of their respective officers, directors, Affiliates, employees, agents or representatives.

(e) No Seller shall be liable to any Purchaser Indemnified Party for any Damages to the extent such Damages constitute punitive damages, except to the extent such punitive damages are sought or obtained by a third party.

(f) The amount of any Damages that are subject to indemnification under this Article XII shall be calculated net of the amount of any insurance proceeds, contribution, indemnification payments or similar payments or reimbursements actually received by the Purchaser Indemnified Parties in respect of such Damages (net of any costs or expenses incurred in obtaining such insurance, indemnification or reimbursement, including any increases in insurance premiums or retro-premium adjustments resulting from such recovery), provided, that nothing in this Section 12.03(f) shall be construed as or give rise to an obligation to seek any such insurance, indemnification or reimbursement. No Purchaser Indemnified Party shall have any right of indemnification hereunder with respect to any Damages or alleged Damages to the extent that the Damage or alleged Damage is included in the calculation of Net Working Capital or deducted as Indebtedness or Transaction Expenses in the determination of Final Merger Consideration.

***Confidential Treatment Requested

(g) All indemnification payments made to the Purchasers from the Escrow Account shall be treated by the parties as an adjustment to the proceeds received by the Sellers pursuant to Article I of this Agreement.

(h) Notwithstanding anything to the contrary contained in this Agreement, the Purchaser Indemnified Parties shall not be entitled to any indemnification for Taxes attributable to transactions occurring on the Closing Date after the Closing outside the Ordinary Course of Business (other than as explicitly contemplated by this Agreement) or transactions that occur or are deemed to occur at or immediately prior to or immediately following the Closing that are solely attributable to Purchaser’s financing of the transactions contemplated by this Agreement.

12.04 Indemnification Claims Procedure.

(a) If a Purchaser Indemnified Party determines in good faith that such Purchaser Indemnified Party has a bona fide claim for indemnification pursuant to this Article XII, then the Purchaser (on behalf of any Purchaser Indemnified Party) shall deliver to the Representative a written notice (a “Claim Notice”) (i) stating that a Purchaser Indemnified Party has a claim for indemnification pursuant to this Article XII, (ii) to the extent possible, providing a good faith non-binding, preliminary estimate of the amount of indemnifiable Damages such Purchaser Indemnified Party claims to have incurred or suffered or could reasonably be expected to incur or suffer (the “Estimated Claim Amount”); and (iii) specifying in reasonable detail (based upon the information then possessed by such Purchaser Indemnified Party) the material facts known to the Purchaser Indemnified Party giving rise to such claim. Subject to this Article XII, no delay in providing such a Claim Notice shall affect a Purchaser Indemnified Party’s rights hereunder, unless (and then only to the extent that) the Sellers are actually and materially prejudiced by such delay. At the time of delivery of any Claim Notice, the Purchaser shall deliver a duplicate copy of such Claim Notice to the Escrow Agent (on behalf of the applicable Purchaser Indemnified Party).

(b) If the Representative in good faith objects to any claim made in a Claim Notice, then the Representative shall deliver a written notice (a “Claim Dispute Notice”) to the Purchaser and the Escrow Agent during the […***…] calendar day period commencing upon receipt by the Representative of the Claim Notice. The Claim Dispute Notice shall set forth in reasonable detail the principal basis for the dispute of any claim made in the relevant Claim Notice. If no Claim Dispute Notice is delivered prior to the expiration of such […***…] calendar day period, then (i) each claim for indemnification set forth in such Claim Notice shall be deemed to have been conclusively determined in favor of the Purchaser Indemnified Party for purposes of this Article XII on the terms set forth in the Claim Notice and (ii) as applicable, if any funds remain in the Escrow Account, then the Purchaser may, in its sole and absolute discretion, direct the Escrow Agent to deliver cash from the Escrow Account to the Purchaser in accordance with this Section 12.04, or as otherwise required pursuant to this Article XII, the Sellers shall make payment to the Purchaser Indemnified Party in respect of the Damages set forth in such Claim Notice.

(c) Following delivery of a Claim Dispute Notice, the Purchaser and the Representative shall attempt in good faith to resolve any such objections raised in such Claim Dispute Notice. If the Purchaser and the Representative agree to a resolution of such objection,

***Confidential Treatment Requested

then (i) a memorandum setting forth the matters conclusively determined by the Purchaser and the Representative shall be prepared and signed by both parties and (ii) as applicable, if such memorandum calls for a payment to a Purchaser Indemnified Party and any funds remain in the Escrow Account, the Purchaser may, in its sole and absolute discretion, direct the Escrow Agent to act in accordance with such memorandum and distribute cash from the Escrow Account in accordance therewith, or as otherwise required pursuant to this Article XII, the Sellers shall make payment to the Purchaser Indemnified Party in accordance with such memorandum.

(d) If no such resolution can be reached during the […***…] calendar day period following receipt of a given Claim Dispute Notice, then upon the expiration of such […***…] calendar day period, either the Purchaser or the Representative may bring suit to resolve the objection in accordance with Sections 12.14 and 12.18 and 12.19. The decision of the trial court as to the validity and amount of any claim in such Claim Notice shall be non-appealable, binding and conclusive upon the Purchaser and the Sellers. As applicable, if such decision calls for a payment to a Purchaser Indemnified Party and any funds remain in the Escrow Account, the Purchaser may, in its sole and absolute discretion, direct the Escrow Agent to act in accordance with such decision and distribute cash from the Escrow Account in accordance therewith, or as otherwise required pursuant to this Article XII, the Sellers shall make payment to the Purchaser Indemnified Party in accordance with such decision. Judgment upon any award rendered by the trial court may be entered in any court having competent jurisdiction.

12.05 Third Party Claims. In the event of the assertion of any actual or possible Proceeding that has been or may be brought or asserted by a third party against a Purchaser Indemnified Party and that may be subject to indemnification pursuant to this Agreement (each, a “Third-Party Claim”), the Purchaser shall proceed with the defense of such Third-Party Claim on its own (and the costs and expenses incurred by the Purchaser in connection with the defense, settlement or resolution of such Third-Party Claim (including reasonable attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs) may be included in the Damages for which the Purchaser may seek indemnification pursuant to a claim made hereunder). Representative shall be entitled to participate in the defense of such action, lawsuit, proceeding, investigation or other claim giving rise to the Purchaser’s claim for indemnification under this Agreement at Representative’s expense, and at its option shall be entitled to assume the defense thereof with reputable counsel reasonably acceptable to the Purchaser; provided that Representative shall continue to be entitled to assert any limitation on any claims contained herein; and provided further that Representative shall not have the right to assume control of such defense if (i) the claim which Representative seeks to control (a) involves a claim that is reasonably likely to have a material adverse effect on the reputation, customer or supplier relations or future business prospects of the Purchasers, the Surviving Company or any of their respective Affiliates, (b) seeks equitable or injunctive relief, except where equitable or injunctive relief is incidental to a primary claim or claims for monetary damages and such claim is not reasonably likely to result in equitable or injunctive relief, (c) is brought by a Governmental Entity, (d) involves criminal allegations or (e) would reasonably be expected to result in greater liability to Purchaser Indemnified Parties than the Sellers, taking into account the Indemnity Deductible, the Escrow Amount and other limitations on indemnification herein or (ii) the Representative (or counsel selected by Representative) has failed or is failing to prosecute or defend such claim, and is provided written notice of such failure by the Purchaser Indemnified Party and such failure is not reasonably cured within […***…] Business Days of receipt of

***Confidential Treatment Requested

such notice. In the event that the Representative assumes the defense of any Third-Party Claim pursuant to the prior sentence, the Purchaser shall be entitled to participate in the defense of such Third Party Claim with separate counsel at the Purchaser’s expense. Neither the Purchaser nor Representative shall not have the right to settle, adjust or compromise such Third-Party Claim without the consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), it being agreed that the other party shall consent to any settlement, adjustment or compromise of such Proceeding unless the settlement will result in injunctive or other equitable relief being imposed against the Sellers, on the one hand, or against the Purchaser or any member of the Company Group, on the other, as the case may be, or the settlement does not expressly and unconditionally release the Sellers, on the one hand, or the Purchaser or the Company Group, on the other, as applicable, from all liabilities and obligations with respect to such Third-Party Claim without prejudice, except for payments that would be required to be paid by Representative representing the Indemnity Deductible and/or the Per Claim Deductible. The Purchasers shall give the Representative prompt notice of the commencement of any such Third-Party Claim against a Purchaser Indemnified Party; provided, that any failure on the part of the Purchaser to so notify the Representative shall not limit any of the obligations of the Sellers pursuant to this Article XII (except and only to the extent such failure actually and materially prejudices the defense of such Third-Party Claim). For the avoidance of doubt, Tax Claims shall be subject to Section 9.03(i) rather than this Section 12.05.

12.06 Release of Escrow Amount.

(a) On the […***…] Business Day following the termination of the Escrow Period, the Escrow Agent shall release the then remaining Escrow Funds (to the extent such funds have not been utilized to pay the Purchaser Indemnified Parties for any indemnification claims under this Article XII) to (i) the Paying Agent for further distribution to the Sellers (other than the Optionholders in respect of Options) and (ii) the Surviving Company (or any successor thereto) for further distribution to the Optionholders in respect of the Options, in each case, in accordance with Section 1.04 and Section 1.05, as applicable; provided, that the Escrow Agent shall retain an amount (up to the total amount of the then remaining Escrow Funds) equal to the amount of any claims for indemnification asserted in good faith prior to the termination of the Escrow Period but which are not yet resolved (each such claim, an “Unresolved Claim”). The amount of the Escrow Funds retained for each Unresolved Claim shall be released (to the extent such funds are not utilized to indemnify any Purchaser Indemnified Party for such Unresolved Claim in accordance with the terms of this Agreement) by the Escrow Agent to the Paying Agent or the Surviving Company, as applicable, in accordance with the prior sentence upon the final and binding resolution of such Unresolved Claim in accordance with this Article XII and the Escrow Agreement.

(b) Notwithstanding anything herein to the contrary, at least […***…] Business Days prior to any Escrow Distribution to the Sellers, the Representative shall deliver to the Purchasers an updated Closing Payment Schedule (which need not be certified by an officer of the Company) setting forth the portion of such Escrow Distribution payable to each Seller.

***Confidential Treatment Requested

12.07 Representative.

(a) Authority. By the approval of this Agreement pursuant to the Delaware LLC Law, the Sellers hereby irrevocably constitute and appoint the Representative as the representative, agent, proxy, and attorney-in-fact for each of the Sellers for all purposes authorized under this Agreement, including the full power and authority on the Sellers’ behalf (i) to consummate the transactions contemplated herein; (ii) to pay such Seller’s expenses incurred in connection with the negotiation and performance of this Agreement (whether incurred on or after the date hereof), including by using funds from the Representative Holdback Amount; (iii) to disburse any funds received hereunder to such Seller and each other Seller; (iv) to endorse and deliver any certificates or instruments representing the Units and execute such further instruments of assignment as the Purchaser or the Merger Sub shall reasonably request; (v) to execute and deliver on behalf of such Seller any amendment or waiver hereto; (vi) (A) to dispute or refrain from disputing, or to deliver instructions, on behalf of such Seller relative to any amounts to be received by such Seller under any Transaction Document or any other agreement contemplated hereby or thereby, any claim made by the Purchaser under any Transaction Document or any other agreement contemplated hereby or thereby, (B) to negotiate and compromise, on behalf of such Seller, any dispute that may arise under, and exercise or refrain from exercising any remedies available under, the Transaction Documents or any other agreement contemplated hereby or thereby (including pursuant to Article XII of this Agreement), and (C) to execute, on behalf of such Seller, any settlement agreement, release or other document with respect to such dispute or remedy; (vii) to engage attorneys, accountants, agents or consultants on behalf of the Sellers in connection with the Transaction Documents or any other agreement contemplated hereby or thereby and paying any fees related thereto; (viii) to take all other actions to be taken by or on behalf of such Seller in connection herewith; (ix) to retain the Representative Holdback Amount and pay amounts therefrom in accordance with this Agreement; and (x) to do each and every act and exercise any and all rights which such Seller or the Sellers collectively are permitted or required to do or exercise under this Agreement or any other Transaction Document; provided, however, that, notwithstanding the foregoing, the Representative shall not have the authority to agree to any amendment of this Agreement or enter into any agreement or take any of the foregoing actions that would treat any Units differently than other Units. Each of the Sellers agrees that such agency and proxy are coupled with an interest, are therefore irrevocable without the consent of the Representative and shall survive the death, incapacity, bankruptcy, dissolution or liquidation of any Seller. If any Seller dies or becomes incapacitated, disabled or incompetent (such deceased, incapacitated, disabled or incompetent Seller being a “Former Seller”) and, as a result, the agency and power of attorney conferred by this Section 12.07 is revoked by operation of law, it shall not be a breach by such Former Seller under this Agreement if the heirs, beneficiaries, estate, administrator, executor, guardian, conservator or other legal representative of such Former Seller (each a “Successor Seller”) confirms the appointment of the Representative as agent and attorney-in-fact for such Successor Seller. All decisions and actions by the Representative (to the extent authorized by this Agreement) shall be binding upon all of the Sellers, and no Seller shall have the right to object, dissent, protest or otherwise contest the same.

(b) Authority; Indemnification. Each Seller agrees that the Purchasers, the Merger Sub and the Surviving Company shall be entitled to rely on any action taken by the Representative, on behalf of such Seller, pursuant to Section 12.07(a) above (an “Authorized

Action”), and that each Authorized Action shall be binding on each Seller as fully as if such Seller had taken such Authorized Action. The Purchasers and the Merger Sub agree that the Representative, as the Representative, shall have no Liability to the Purchaser and the Merger Sub for any Authorized Action, except to the extent that such Authorized Action is found by a court of competent jurisdiction to have constituted fraud or willful misconduct. Each Seller hereby severally (based on such Seller’s Residual Percentage), for itself only and not jointly and severally, agrees to indemnify and hold harmless the Representative against all fees, costs and expenses (including reasonable attorneys’ fees), judgments, fines and amounts incurred by the Representative in connection with any action, suit or proceeding to which the Representative is made a party by reason of the fact it is or was acting as the Representative pursuant to the terms of this Agreement.

(c) Exculpation. The Representative shall not have by reason of this Agreement a fiduciary relationship in respect of any Seller, except in respect of amounts received on behalf of such Seller. The Representative shall not be liable to any Seller for any action taken or omitted by it or any agent employed by it hereunder or under any other document entered into in connection herewith, except that the Representative shall not be relieved of any Liability imposed by law for willful misconduct. The Representative shall not be liable to the Sellers for any apportionment or distribution of payments made by the Representative in good faith, and if any such apportionment or distribution is subsequently determined to have been made in error the sole recourse of any Seller to whom payment was due, but not made, shall be to recover from other Sellers any payment in excess of the amount to which they are determined to have been entitled. The Representative shall not be required to make any inquiry concerning either the performance or observance of any of the terms, provision or conditions of this Agreement.

Reference is made to that certain Agreement and Plan of Merger, dated as of January 13, 2016, (“Merger Agreement”), by and among Crealta Holdings LLC, a Delaware limited liability company (“Company”), Criostail LLC, a Delaware limited liability company (“Merger Sub”), Horizon Pharma USA, Inc., a Delaware corporation […***…], HZNP Limited, a private company limited by shares organized under the laws of Ireland (“Purchaser,” and together with […***…], “Purchasers”), […***…] and GTCR Fund X/B LP, a Delaware limited partnership. Capitalized terms used herein but not defined shall have the meanings specified in the Merger Agreement.

In connection with the merger of Merger Sub with and into Company pursuant to the Merger Agreement (the “Merger”), and as part of the transactions described in the Merger Agreement, the undersigned hereby surrenders the below-described unit certificate(s) (the “Certificate(s)”) representing the Company’s Units (“Company Units”), in exchange for the right to receive, on the terms and subject to the conditions set forth in the Merger Agreement, an amount of cash equal to the Allocable Portion of the Closing Merger Consideration attributable to such Company Unit plus any Additional Merger Consideration attributable to such Company Unit plus any Escrow Distribution attributable to such Company Unit, at the times specified therein.

The undersigned (i) acknowledges that the undersigned has reviewed the Merger Agreement, and understands that the only consideration that the undersigned may be entitled to receive with respect to the undersigned’s Company Units in connection with the Merger is the consideration pursuant to the Merger Agreement (ii) consents to to the adoption and approval of the Merger Agreement and the transactions contemplated thereby, (iii) irrevocably waives any right of dissent under applicable law and (iv) affirms the undersigned’s appointment of the Representative (as defined in the Merger Agreement) pursuant to Section 12.07I of the Merger Agreement (including the limitations set forth therein), which is incorporated by reference herein.

The undersigned acknowledges that, until surrendered in accordance with the terms of the Merger Agreement, each outstanding certificate representing Company Units will be deemed from and after the effective time of the Merger, for all purposes, to evidence only the right to receive cash amounts on the terms and subject to the conditions set forth in the Merger Agreement.

Unless otherwise indicated, the name and address of the owner of the Company Units represented by the Certificate(s) are correctly identified in the table entitled “Description of Units Surrendered” below. The undersigned represents and warrants that the undersigned is the owner of such units or has full power and authority to surrender the Certificate(s) on behalf of such owner, free and clear of all liens, claims and encumbrances. The undersigned will, upon request, execute and deliver any additional documents (the “Additional Documents”) reasonably deemed appropriate or necessary by Continental Stock Transfer & Trust Company (the “Paying Agent”) in connection with the surrender of the Certificate(s), and hereby permits the Paying Agent to send a copy of this Letter of Transmittal and any Additional Documents to the Purchaser. All authority conferred or agreed to be conferred in this Letter of Transmittal shall not be affected by, and shall survive, the undersigned’s death or incapacity, and all of the undersigned’s obligations under this Letter of Transmittal shall be binding upon the undersigned’s successors, assigns, heirs, executors, administrators and legal representatives.

The undersigned understands that surrender of the Certificate(s) will not be in acceptable form until receipt by the Paying Agent of this Letter of Transmittal, duly completed and signed with an original signature, together with all and any Certificate(s).

All questions as to validity, form and eligibility of any surrender of the Certificate(s) hereunder will be determined by the Purchaser (which may delegate power in whole or in part to the Paying Agent) in its reasonable discretion and such determination shall be final and binding. The undersigned understands that delivery of any cash amounts to which the holder of the Certificate(s) is entitled will be made as promptly as practicable after surrender of the Certificate(s) along with the properly completed and executed Letter of Transmittal; provided, however, that the actual amount of consideration to be received by the undersigned is subject to adjustment and the results of certain post-Closing items. The undersigned understands and agrees that a portion of the consideration to which the undersigned may be entitled under the Merger Agreement will be included in (i) escrow funds that will be delivered to an escrow agent (the “Escrow Agent”) and held in escrow pursuant to Section 3.02(e) of the Merger Agreement

***Confidential Treatment Requested

and the terms of the escrow agreement executed among the Escrow Agent, the Representative, the Purchaser and certain other parties thereto on the closing of the Merger (the “Escrow Agreement”), with such amounts to be disbursed by the Escrow Agent in accordance with the Escrow Agreement and (ii) a holdback amount which will be delivered to the Representative and held by the Representative pursuant to Section 1.08 of the Merger Agreement, with such amount to be disbursed by the Representative in accordance with the Merger Agreement. The undersigned further understands that the undersigned may in the future become entitled to receive all, a portion or none of the cash deposited in escrow with the Escrow Agent and of the holdback amount held by the Representative pursuant to Section 1.08 of the Merger Agreement.

The undersigned hereby acknowledges receipt of the documents delivered with this Letter of Transmittal, including, without limitation the Merger Agreement and a Form W-9 or Form W-8 (collectively with this Letter of Transmittal, the “Specified Documents”). The undersigned acknowledges that the undersigned has had the opportunity to review the Specified Documents, that the undersigned has consulted, or had the full opportunity to consult, with independent legal, tax, accounting, regulatory and financial advisors regarding the undersigned’s rights and obligations under the Specified Documents and that the undersigned fully understands the terms and conditions contained, and the transactions provided for, herein and therein. The undersigned further acknowledges and agrees to follow the instructions in the “Instructions” section in this Letter of Transmittal.

The undersigned hereby irrevocably constitutes and appoints the Representative as the true and lawful agent, proxy and attorney-in-fact of the undersigned with respect to the Company Units listed in the “Description of Units Surrendered” section of this Letter of Transmittal, and any and all rights represented thereby, with full power of substitution and resubstitution (such power of attorney being deemed to be an irrevocable power coupled with an interest) and authority, to act in the name, place and stead of the undersigned for purposes of executing any documents and taking any actions that the Representative may, in its sole discretion, determine to be necessary, desirable or appropriate within the bounds of the Representative’s authority under the express terms of the Merger Agreement, including in connection with any claim for indemnification, compensation or reimbursement under Article XII of the Merger Agreement or any of the transactions contemplated thereby (subject to the limitations set forth therein). The authority herein conferred or agreed to be conferred shall not be affected by, and shall survive, the death, incapacity or dissolution of the undersigned, and all grants, appointments, acknowledgments, conveyances, deliveries, waivers and obligations of the undersigned hereunder shall be binding upon the heirs, executors, administrators, trustees in bankruptcy, personal and legal representatives, successors and assigns of the undersigned. This transmittal, and the surrender of Company Unit(s) transmitted by this Letter of Transmittal, are irrevocable, provided that, if the Transaction is not consummated, this Letter of Transmittal will be returned to the undersigned.

The provisions of this Letter of Transmittal may be amended or waived only with the prior written consent of the Company, the Representative and the undersigned.

THE UNDERSIGNED HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS LETTER OF TRANSMITTAL OR THE ACTIONS OF THE PARTIES HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

The undersigned understands and agrees that the method of delivery of the Company Units and this Letter of Transmittal is at the election and risk of the holder of the Company Units. The undersigned hereby acknowledges that the undersigned has read the “Instructions” section in this Letter of Transmittal.

With respect to the undersigned’s surrendered Company Units, this Letter of Transmittal shall be void and of no force and effect if the Closing pursuant to the Merger Agreement fails to occur for any reason and the Merger Agreement is terminated in accordance with its terms.

The undersigned hereby (i) forever waives all dissenter’s, appraisal or similar rights under Delaware law and any other applicable laws, and (ii) withdraws all written objections to the Merger and/or demands for appraisal, if any, with respect to the Company Units owned by the undersigned.

All questions as to validity, form and eligibility of any surrender of Company Units hereby will be determined by Purchaser (which may delegate power in whole or in part to the Paying Agent) and such determination shall be final and binding; provided that if there are any defects in the surrender of the Certificate(s), Purchaser or the Paying Agent shall give notice of such defects to the named unitholder. Purchaser reserve the right to waive any

irregularities or defects in the surrender of any Company Units and its interpretations of the terms and conditions of the Merger Agreement and of this Letter of Transmittal (including these instructions) with respect to such irregularities or defects shall be final and binding.

Letter of Transmittal Required; Surrender of Certificate(s); Lost Certificate(s).

You will not receive any consideration for your Company Units unless and until you deliver this Letter of Transmittal or a facsimile hereof, duly completed and signed, with original signature to the Paying Agent, together with the Certificate(s) representing such Company Units and any required accompanying evidences of authority in form satisfactory to Purchaser. If the Certificate(s) has (have) been lost or destroyed, such fact should be indicated on the face of this Letter of Transmittal. In such event, the Paying Agent will forward additional documentation and instructions necessary to be completed in order to effectively surrender the Company Units represented by such lost or destroyed Certificate(s) (including instructions relating to payment by holder of such lost or destroyed Certificate(s) of an indemnity/surety bond premium equal to 3% of the cash value of the Company Units represented by such Certificate(s) with a minimum of $100.00. No interest will be paid on amounts due for the Company Units.

11. Form W-9. Each unitholder surrendering Units for payment is required to provide the Paying Agent with such holder’s correct Taxpayer Identification Number (“TIN”) and certain other information on a Form W-9 (included in this Letter of Transmittal), or an appropriate IRS Form W-8, as described below. Failure to provide such information or an adequate basis for exemption from backup withholding on the form may subject such holder to federal income tax withholding on cash payments made with respect to certificates by the Payor (as defined below). Please consult the instructions to the enclosed Form W-9 for instructions on how to complete the Form W-9.

IMPORTANT TAX INFORMATION

United States federal income tax law generally requires that if your units are accepted for payment and you are a U.S. Person (as defined below), you or your assignee (in either case, the “Payee”), must provide Purchaser (the “Payor”) with the Payee’s correct TIN, which, in the case of a Payee who is an individual, is generally the Payee’s social security number. If the Payor is not provided with the correct TIN or an adequate basis for an exemption, the Payee may be subject to a $50 penalty imposed by the IRS and backup withholding in an amount equal to 28% (or the then-prevailing rate) of the proceeds received by the Payee pursuant to the Merger. Backup withholding is not an additional tax. Rather, the tax liability of a person subject to backup withholding will be reduced by the amount withheld by the Payor (through the Paying Agent). If withholding results in an overpayment of taxes, a refund may be obtained from the IRS, provided the appropriate information and forms are provided to the IRS and other requirements are satisfied.

To prevent backup withholding, each Payee that is a U.S. Person must provide such Payee’s correct TIN by completing the Form W-9 set forth herein, certifying that (i) the TIN provided is correct, (ii) (a) the Payee is exempt from backup withholding, (b) the Payee has not been notified by the IRS that such Payee is subject to backup withholding as a result of a failure to report all interest or dividends, or (c) the IRS has notified the payee that such Payee is no longer subject to backup withholding, and (iii) the Payee is a U.S. Person (including a U.S. resident alien). For these purposes, a “U.S. Person” is (a) an individual who is a U.S. citizen or U.S. resident alien, (b) a partnership, corporation, company or association created or organized in the United States or under the laws of the United States, (c) an estate (other than a foreign estate), or (d) a domestic U.S. trust (as defined in Treasury Regulation Section ###-###-####-7)).

If the Payee does not have a TIN, such Payee should apply for and receive a TIN prior to submitting the Form W-9; please consult the instructions to the enclosed Form W-9 (the “W-9 Instructions”) for instructions on applying for a TIN. If the Payee does not provide such Payee’s TIN to the Payor by the time of payment, backup withholding will apply.

If the Company Units are held in more than one name or held in a name other than the name of the actual owner, consult the W-9 Instructions for information on which TIN to report.

Exempt Payees are not subject to these backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt Payee that is a U.S. Person should check the “exempt from backup withholding” box on the Form W-9. See the W-9 Instructions for additional instructions. In order for a Payee that is not a U.S. Person to avoid backup withholding, such Payee must submit an appropriate and properly completed Form W-8BEN, W-8BEN-E, W-8ECI, W-8EXP or W-8IMY, signed under penalties of perjury. Such forms, as well as instructions for the same, may be obtained from the IRS at its Internet website: www.irs.gov.

Rules of Engagement for Accounting Firm

If an Accounting Firm is engaged pursuant to Section 2.01, the parties will instruct the Accounting Firm to analyze and resolve the parties’ dispute in accordance with the following guidelines (which guidelines and relevant portions of this Agreement the Accounting Firm will be required to review and commit to acting in accordance with):

Retainer and Fees

The fees, costs and expenses of the Accounting Firm shall be borne by the parties in inverse proportion to the relative success of the parties relating to the disputed items submitted to the Accounting Firm, with such determination of relative success made by the Accounting Firm, or if the Accounting Firm is unwilling to make such a determination, then such fees, costs and expenses shall be borne 50% by the Purchaser and 50% by the Representative (on behalf of the Sellers).

To the extent the Accounting Firm requires a retainer or payment of expenses prior to its final determination, the Purchaser and the Representative (on behalf of the Sellers) will each pay 50% of any retainer and, during the engagement, the Accounting Firm will bill 50% of the total charges to the Purchaser and 50% of the total charges to the Representative (on behalf of the Sellers). Such fees, costs and expenses of the Accounting Firm shall be adjusted, if necessary, pursuant to the first paragraph of this “Retainer and Fees” section.

Parameters of Arbitration

Except as permitted herein in order to clarify or understand any position or argument made by a party in its written submission, the Accounting Firm’s determination of the Net Working Capital, the Closing Date Indebtedness, the Transaction Expenses, and the amount of the Closing Date Cash and the resulting Final Merger Consideration shall be based solely on written presentations submitted by the Purchaser and the Representative which are in accordance with the guidelines and procedures (including the definitions of Closing Date Cash, Closing Date Indebtedness, Transaction Expenses and Net Working Capital) set forth in this Agreement (i.e., not on the basis of an independent review). The Accounting Firm shall consider only the disputed matters that were included in the Objections Statement and the Accounting Firm may not assign a value to any item in dispute greater than the greatest value assigned by the Purchaser in the Preliminary Statement, on the one hand, or the Representative in the Objections Statement, on the other hand, or less than the smallest value for such item assigned by the Purchaser in the Preliminary Statement, on the one hand, or the Representative in the Objections Statement, on the other hand.

The timetable for these proceedings will be governed by the following procedures:

●

Within fourteen (14) calendar days of retaining the Accounting Firm, each of the Purchaser and the Representative shall submit to the Accounting Firm a memorandum (which may include supporting exhibits) setting forth their respective

positions of all unresolved disputed items in accordance with Section 2.01 of this Agreement (the “Initial Report”).

●

Within one (1) Business Day upon receipt of both the Purchaser’s and the Representative’s Initial Reports, the Accounting Firm will distribute a copy of each Initial Report to the other party.

●

Within fourteen (14) calendar days of receiving the other party’s Initial Report from the Accounting Firm, each of the Purchaser and the Representative may (but shall not be required to) submit to the Accounting Firm a memorandum responding to the Initial Report submitted to the Accounting Firm by the other party (the “Rebuttal Report”). The Rebuttal Report is to be responsive solely to the arguments raised, and information submitted, by the other party in its Initial Report and no party may introduce new arguments or rely on new information in the Rebuttal Report that was not part of such party’s Initial Report or which are not directly responsive to an argument raised by the other party’s Initial Report, except to the extent such new arguments or new information are used in direct response to arguments raised and information submitted by the other party in its Initial Report.

●

Within one (1) Business Day upon receipt of the Rebuttal Reports from the Purchaser and the Representative, the Accounting Firm will distribute a copy of each Rebuttal Report to the other party.

●

At any time before or within fifteen (15) calendar days after the submission of the Initial Reports or any Rebuttal Reports by the Purchaser and the Representative, the Accounting Firm may submit written questions to either party following the procedures set forth below in the Section titled “Submission of Questions by the Accounting Firm.”

●

Upon receipt of the Rebuttal Report or notice waiving the right to file such report from both the Purchaser and the Representative and receipt of all responses to any written questions submitted by the Accounting Firm (and responses thereto), the Accounting Firm will endeavor to issue a report containing its findings within fifteen (15) calendar days after the later of (i) receiving both the Purchaser’s and the Representative’s Rebuttal Reports or notice waiving the right to file such report, as applicable, or (ii) any responses (if any) to any written questions submitted by the Accounting Firm to either party following the procedures set forth below in the Section titled “Submission of Questions by the Accounting Firm.”

●

Unless requested by the Accounting Firm in writing pursuant to the terms of the Section titled “Submission of Questions by the Accounting Firm”, neither the Purchaser nor the Representative may present any additional information or arguments to the Accounting Firm, either orally or in writing.

●

The Accounting Firm shall render its decision without conducting a hearing.

Submission of Questions by the Accounting Firm

After receiving both Initial Reports and Rebuttal Reports, if any, the Accounting Firm may submit written questions to the parties for written responses or may direct requests for additional information, calculations, or supporting documentation to the parties reasonably needed by the Accounting Firm in order to clarify or understand any position or argument made by a party in

its written submission, in which case the parties agree to use commercially reasonable efforts to cooperate with such requests (including, without limitation, by ensuring that the Accounting Firm is provided copies of all relevant records of the business in accordance with Article 1.10(b) of this Agreement) in the manner and procedural timing described in this paragraph. If any such questions are addressed to only one party, the Accounting Firm shall submit the questions to that party, with a copy to the other parties. Once received, the party (or parties) to whom the questions are addressed shall have five (5) Business Days to answer the Accounting Firm’s questions, and shall provide a copy of its written answers to the other party at the time they are provided to the Accounting Firm. In response thereto, the other party may, within five (5) Business Days, submit a response to such answer(s) to the Accounting Firm and shall provide a copy of a response to the other party at the time it is provided to the Accounting Firm. If any such questions are addressed to both parties, each party shall have five (5) Business Days from the date of receipt to respond to the Accounting Firm and shall provide a copy of its written answers to the other parties at the time they are provided to the Accounting Firm. In response thereto, each party may, within five (5) Business Days, submit a response to the other party’s answer(s) to the Accounting Firm and shall provide a copy to the other party at the time it is provided to the Accounting Firm.

Adjustment of Time Periods

If the due date for any written submissions to be submitted to the Accounting Firm falls on a day that is not a Business Day, the written submission shall take place on the next Business Day.

Communication between the Accounting Firm and the Parties

The parties agree not to engage in any ex parte communication with the Accounting Firm.

The Accounting Firm will be required to include a representation in its engagement letter that it has not discussed the substance of the disputed matter with either party prior to its joint retention by the parties, and to include a covenant in its engagement letter not to engage in ex parte communications with either party throughout the course of the engagement.

The engagement letter will specifically require the Accounting Firm to review Article 1.10(b) of this Agreement, as well as any other provisions of this Agreement deemed relevant by any of the Purchaser, the Seller or the Accounting Firm.

Nature of Review by Accounting Firm

The Accounting Firm will make its determination in an objective, impartial manner based on inquiry, investigation, and other procedures as it, in its sole discretion may deem necessary, but in all cases consistent with the terms of this Agreement and this Exhibit D.

The Accounting Firm shall agree that between the time the Representative delivered the Objections Statement to the Purchaser and the date hereof, the Purchaser and the Representative may have exchanged certain proposals relating to the disputed items that were intended solely for purposes of facilitating settlement discussions and such proposals were confidential and were provided solely on the condition and understanding that such proposals would not be permitted to be disclosed in any court or arbitration hearing, including with respect to the Accounting

***Confidential Treatment Requested


Citi Preferred Custody Services – Escrow Agent Agreement		Page 2

The Escrow Agent may act in reliance upon any instructions, notice, certification, demand, consent, authorization, receipt, power of attorney or other writing delivered to it by any of the Parties and reasonably believed by it to be genuine without being required to determine the authenticity or validity thereof or the correctness of any fact stated therein, the propriety or validity of the service thereof, or the jurisdiction of the court issuing any judgment or order. The Escrow Agent may act in reliance upon any signature reasonably believed by it to be genuine, and may assume that such person has been properly authorized to do so.

Each of the Parties (in the case of the Representative, solely on behalf of the Participating Securityholders and in its capacity as the Representative, not in its individual capacity) severally and Jointly, agrees to reimburse the Escrow Agent on demand for, and to indemnify and hold the Escrow Agent harmless against and with respect to, any and all loss, liability, damage or reasonable and documented expense (including, but without limitation, reasonable and documented attorneys’ fees, costs and disbursements) that the Escrow Agent may suffer or incur in connection with this Escrow Agreement and its performance hereunder, except to the extent such loss, liability, damage or expense arises from its fraud, willful misconduct or gross negligence as adjudicated by a court of competent jurisdiction. Notwithstanding anything to the contrary set forth herein, Parent, on the one hand, and the Representative (solely on behalf of the Participating Securityholders and in its capacity as the Representative, not in its individual capacity), on the other hand, agree, solely as between themselves, that any obligation to the Escrow Agent for loss, liability, damage or expense under this subsection (d) of Article First shall be borne by the Party or Parties determined by a court of competent jurisdiction through a final order to be responsible for causing the loss, liability, damage or expense for which the Escrow Agent is entitled to reimbursement; provided, however, that if no such determination is made, then Parent on the one hand and the Representative (solely on behalf of the Participating Securityholders and in its capacity as the Representative, not in its individual capacity), on the other hand, shall each be responsible for 50% of any such losses, liabilities, damages or expenses (it being agreed and understood that, in the event that either Parent, on the one hand, or the Representative (solely on behalf of the Participating Securityholders and in its capacity as the Representative, not in its individual capacity), on the other hand, are obligated to make any payment in excess of 50% of any such losses, liabilities, damages or expenses, the paying Party shall be entitled to reimbursement from the non-paying Party). In no event shall the Escrow Agent be responsible for special, indirect or consequential loss or damage of any kind whatsoever, even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

The Escrow Agent may consult with legal counsel of its selection in the event of any dispute or question as to the meaning or construction of any of the provisions hereof or its duties hereunder, and it shall incur no liability and shall be fully protected in acting in accordance with the opinion and instructions of such counsel in respect of such matters.

The Escrow Agent shall have no obligation to invest or reinvest the property held in escrow if all or a portion of such property is deposited with the Escrow Agent after 11:00 AM Eastern Time on the day of deposit.

The Parties to this Escrow Agreement other than the Escrow Agent acknowledge that they are solely responsible for, and that neither Citibank nor any of its affiliates have any responsibility for, any Party’s compliance with any laws, regulations or rules applicable to the use of the services provided by Citibank under this Escrow Agreement, including, but not limited to, any laws, regulations or rules, in such Party’s jurisdiction or any other jurisdiction, relating to tax, foreign exchange and capital control, and for reporting or filing requirements that may apply as a result of such Party’s country of citizenship, domicile, residence or taxpaying status.

Citigroup, Inc., its affiliates, and its employees are not in the business of providing tax or legal advice to any taxpayer outside of Citigroup, Inc. and its affiliates.

ARTICLE THIRD: The Escrow Agent (a) may, in its sole discretion, resign and terminate its position hereunder at any time following 30 calendar days’ written notice to the Parties to the Escrow Agreement herein or (b) may be removed, with or without cause, by Parent and the Representative acting jointly at any time by providing written notice to the Escrow Agent. Within 30 calendar days after receiving the foregoing notice of resignation from the Escrow Agent or within 30 calendar days after giving the foregoing notice of removal to the Escrow Agent, the Parties shall appoint a successor escrow agent and give notice of such successor escrow agent to the Escrow Agent.
