7.             Amendment is a “Loan Document”.  This Amendment (and, for the avoidance of doubt, the LSAA) is a Loan Document and all references to a “Loan Document” in the Credit Agreement and the other Loan Documents (including, without limitation, all such references in the representations and warranties in the Credit Agreement and the other Loan Documents) shall be deemed to include this Amendment (and the LSAA).

8.             Representations and Warranties; No Default.  Each Loan Party represents and warrants to the Administrative Agent and each Lender that the Budget has been prepared by the Borrower and reflects the Borrower’s good faith estimate of all necessary expenditures and that, after giving effect to this Amendment, (a) the representations and warranties of each Loan Party contained in Article V of the Credit Agreement (other than the Credit Agreement Representation Exclusions) or any other Loan Document, or which are contained in any document furnished at any time under or in connection herewith or therewith, are true, correct and complete in all material respects (except to the extent any such representation or warranty is already qualified by materiality, in which case it shall be true, correct and complete in all respects) on and as of the date hereof, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct in all material respects (except to the extent any such representation or warranty is already qualified by materiality, in which case it shall be true, correct and complete in all respects) as of such earlier date, (b) other than the Specified Events of Default, no Default exists, and (c) no event or circumstance exists or is expected to occur prior to the Bridge Loan Maturity Date which would constitute a violation of any of the terms of any MPT Document other than to the extent waived by MPT.

9.             No Other Changes.  Except as modified hereby, all of the terms and provisions of the Loan Documents shall remain in full force and effect.

10.          Counterparts; Delivery.  This Amendment may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.  Delivery of an executed counterpart of this Amendment by facsimile or other electronic imaging means shall be effective as an original.

11.          Recordation of the Bridge Loans.  Upon execution and delivery hereof, the Borrower will record the Bridge 2 Loans made by the Bridge 2 Lenders in the Register in accordance with Section 11.06(c) of the Credit Agreement (as amended by this Amendment).

12.          FATCA.  For the avoidance of doubt and for purposes of determining withholding Taxes imposed under FATCA, the Borrower and the Administrative Agent shall treat (and the Lenders hereby authorize the Administrative Agent to treat) the Bridge Loans as not qualifying as “grandfathered obligations” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).

13.          Amendment, Modification and Waiver.  This Amendment may not be amended, modified or waived except by an agreement or instrument in writing signed and delivered on behalf of each of the parties hereto.

14.          Governing Law.  This Amendment shall be deemed to be a contract made under, and for all purposes shall be construed in accordance with, the laws of the State of New York.

15.          Acknowledgment of Assignments.  The Loan Parties hereby acknowledge (and consent and agree to) the sale and assignment of all Loans and other Obligations mentioned in the documents attached as Schedule E to the assignee Lenders set forth therein and the Lenders listed on the signature pages to this Amendment (and the appointment of Deerfield Management as successor Administrative Agent as set forth in the LSAA).

16.          Severability.  If any provision of this Amendment is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Amendment shall not be affected or impaired thereby and (b) the parties hereto shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a

provision in a particular jurisdiction or court shall not invalidate or render unenforceable such provision in any other jurisdiction or court.

17.          Reaffirmation. Each Loan Party as debtor, grantor, pledgor, guarantor, assignor, or in any other similar capacity in which such Loan Party grants Liens or security interests in its property or otherwise acts as accommodation party or guarantor, as the case may be, hereby (a) ratifies and reaffirms all of its payment and performance obligations, contingent or otherwise, under each of the Loan Documents to which it is a party (after giving effect hereto) and (b) to the extent such Loan Party granted Liens on or security interests in any of its property pursuant to any such Loan Document as security for or otherwise guaranteed (including the Guaranty) the Obligations and/or its obligations under or with respect to the Loan Documents, ratifies and reaffirms such guarantee (including Guaranty) and grant of security interests and Liens and confirms and agrees that such security interests and Liens hereafter secure (and such guarantees (including the Guaranty) guarantee) all of the Obligations as amended hereby.  Each of the Loan Parties hereby consents to this Amendment and acknowledges that each of the Loan Documents remains in full force and effect and is hereby ratified and reaffirmed.  The execution of this Amendment shall not (i) operate as a waiver of any right, power or remedy of the Administrative Agent and the Lenders, (ii) constitute a waiver of any provision of any of the Loan Documents or (iii) serve to effect a novation of the Obligations.

18.          Ratification of Liability; Acknowledgment of Rights.  Each Loan Party hereby ratifies and confirms its respective liabilities, obligations (including Obligations), guarantees (including the Guaranty) and agreements under the Credit Agreement and the other Loan Documents and the Liens and security interests created thereby, and acknowledges that: (i) it has no defenses, claims or set-offs to the enforcement by the Administrative Agent or any Lender of such liabilities, obligations (including Obligations), guarantees (including the Guaranty) and agreements; and (ii) the Administrative Agent and the Lenders (in each case, including their predecessors) have fully performed all undertakings owed to such Loan Party as of the date hereof.

19.          No Disregard of Loan Documents.  Each Loan Party acknowledges that the parties hereto have not entered into a mutual disregard of the terms and provisions of the Credit Agreement or the other Loan Documents, or engaged in any course of dealing in variance with the terms and provisions of the Credit Agreement or the other Loan Documents, within the meaning of any applicable Law of the State of New York or otherwise.

20.          Effect on Loan Documents.

(a)           The Credit Agreement and each of the other Loan Documents shall be and remain in full force and effect in accordance with their respective terms and hereby are ratified and confirmed in all respects.  The execution, delivery, and performance of this Amendment shall not operate, except as expressly set forth herein, as a forbearance, waiver, consent or modification of any right, power,

12

or remedy of the Administrative Agent or any lender under the Credit Agreement or any other Loan Document.  The forbearance, waivers, consents and modifications herein are limited to the specifics hereof (including facts or occurrences on which the same are based), shall not apply with respect to any facts or occurrences other than those on which the same are based, shall not excuse any non-compliance with the Loan Documents, and shall not operate as a consent to any matter under the Loan Documents.  Except for the forbearance. waivers, consents and other modifications expressly set forth above, the text of the Credit Agreement and all other existing Loan Documents shall remain unchanged and in full force and effect and the Administrative Agent and each Lender expressly reserves the right to require strict compliance with the terms of the Credit Agreement and the other Loan Documents.  Neither the Administrative Agent nor any Lender is obligated to consider or consent to any additional request by any Loan Party for any other forbearance, waiver, consent or other modification with respect to the Credit Agreement or any other Loan Document.  To the extent that any terms, conditions or provisions of this Amendment shall contradict or be in conflict with any terms, conditions or provisions of the Credit Agreement or the other Loan Documents, after giving effect to this Amendment, such terms, conditions and provisions are hereby deemed modified or amended accordingly to reflect the terms and conditions of the Credit Agreement and the other Loan Documents as modified or amended hereby.

(b)           Upon and after the effectiveness of this Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, “herein”, “hereof” or words of like import referring to the Credit Agreement, and each reference in the other Loan Documents to “the Credit Agreement”, “thereunder”, “therein”, “thereof” or words of like import referring to the Credit Agreement, shall mean and be a reference to the Credit Agreement as modified and amended hereby.

(c)           The provisions of Sections 1.02, 11.14(b), 11.14(c), 11.14(d) and 11.15 of the Credit Agreement shall be incorporated herein mutated mutandis.

21.          No Waiver; Cumulative Remedies.  No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.  The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

22.          Headings.  The headings listed herein are for convenience only and do not constitute matters to be construed in interpreting this Amendment.

23.          Construction.  This Amendment shall not be construed more strictly against the Administrative Agent or any Lender merely by virtue of the fact that the same has been prepared by the Administrative Agent, any Lender or their respective counsel, it being recognized that the  Loan Parties, the Administrative Agent and the Lenders have contributed substantially and materially to the preparation of this Amendment, and each party acknowledges and waives any claim contesting the existence and the adequacy of the consideration given by any of the other parties hereto in entering into this Amendment.

24.          Relationship of Loan Parties and the Administrative Agent and the Lenders.  The relationship between the Loan Parties, on the one hand, and the Administrative Agent and the Lenders, on the other hand, is solely that of debtor and creditor, and the Administrative Agent and the Lenders have no fiduciary or other special relationship with the Loan Parties, and no term or condition of this Amendment or any other Loan Document shall be construed so as to deem the relationship between the Loan Parties, on the one hand, and the Administrative Agent and the Lenders, on the other hand, to be other than that of debtor and creditor.
