5)             Effectiveness.  This Amendment shall become effective on and as of October 2, 2014 (the “Effective Date”), so long as each of the following conditions precedent shall have been satisfied or waived, as determined by the Agent, on or prior to such date:  (a) the Agent shall have received this Amendment, duly executed and delivered by each Borrower and Guarantor; and (b) the Agent shall have received an amendment to the existing forbearance agreement with respect to the Term Debt in form and substance reasonably satisfactory to Agent, duly executed and delivered by the Borrower, the Term Debt Required Lenders and the Term Debt Agent; provided, however, that this Amendment shall immediately cease to be effective as of 5:00 p.m. New York time on October 3, 2014 (and the Forbearance Period Termination Date shall thereupon be deemed to have occurred) if the Borrowers shall have failed by such time to pay all costs and expenses of outside legal counsel to the Agent invoiced to the Borrowers on or prior to October 3, 2014.

6)             Costs, Fees and Expenses.  Without limiting the obligations of the Borrowers or any Guarantor under the Revolving Credit Agreement or the Other Documents, the Borrowers ratify and reaffirm their reimbursement and indemnification obligations under Sections 16.5 and 16.9 of the Revolving Credit Agreement, including without limitation, their obligation to pay all out-of-pocket costs and expenses, including without limitation, the fees and disbursements of counsel and the fees and expenses of any accountants and financial advisors engaged by Agent or Required Lenders, incurred by the Agent in connection with this Amendment and the administration and enforcement of the Forbearance Agreement and the transactions contemplated hereby.

On and after the Effective Date, each reference in or to the “Forbearance Agreement,” “thereunder,” “thereof” or words of like import referring to the Forbearance Agreement shall mean and be a reference to the Forbearance Agreement, as amended by this Amendment.  All representations and warranties of the Borrowers and any Guarantors set forth in the Forbearance Agreement shall be deemed to have been remade on the date hereof, after giving effect to this Amendment.  Each Borrower and Guarantor reconfirms and ratifies the Revolving Credit Agreement, the Other Documents and all other documents executed in connection therewith except to the extent the Forbearance Agreement is expressly modified by this Amendment; and each Borrower and Guarantor

confirms that all such documents have remained in full force and effect since the date of their execution. This Amendment (subject to Section 5 hereof) shall be effective upon execution and delivery by Borrowers, the Agent and the Consenting Lenders.

9)             Loan Party Release; Covenant Not to Sue.

(a)         Release.  In consideration of the delivery of this Amendment and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, unconditionally, freely and voluntarily, after consultation with counsel and becoming fully and adequately informed as to the relevant facts, circumstances and consequences, each Borrower and Guarantor, for itself and on behalf its successors and assigns, and its present and former members, affiliates, subsidiaries, divisions, predecessors, directors, officers, attorneys, employees, agents, legal representatives and other representatives, and any Person acting for or on behalf of, or claiming through it (each Borrower and Guarantor and all such other Persons being hereinafter referred to collectively as the “Releasing Parties” and individually as a “Releasing Party”), hereby waives, releases, remises and forever discharges the Agent and each Lender, and each of their respective Affiliates, and each of their respective successors in title, past, present and future officers, directors, employees, limited partners, general partners, investors, attorneys, assigns, subsidiaries, shareholders, trustees, agents and other professionals and all other persons and entities to whom the Agent or any Lender would be liable if such persons or entities were found to be liable to any Borrower or Guarantor (each a “Releasee” and collectively, the “Releasees”), from any and all past, present and future claims, suits, liens, lawsuits, adverse consequences, amounts paid in settlement, debts, deficiencies, diminution in value, disbursements, demands, obligations, liabilities, causes of action, damages, losses, costs and expenses of any kind or character, whether based in equity, law, contract, tort, implied or express warranty, strict liability, criminal or civil statute or common law (each a “Claim” and collectively, the “Claims”), whether known or unknown, fixed or contingent, direct, indirect, or derivative, asserted or unasserted, matured or unmatured, foreseen or unforeseen, past or present, liquidated or unliquidated, suspected or unsuspected, which any Releasing Party ever had from the beginning of the world, now has, or might hereafter have against any such Releasee, which Claims relate, directly or indirectly, to any act or omission by any Releasee that occurred on or prior to the date of this Agreement and relate, directly or indirectly, to the Revolving Credit Agreement, any Other Document, any Borrower or Guarantor or any acts or omissions of any such Releasee that occurred on or prior to the date of this Agreement with respect to the Revolving Credit Agreement or any Other Document, any Borrower or Guarantor or the lender-borrower relationship evidenced by the Other Documents, except for the duties and obligations set forth in this Agreement and the duties and obligations set forth in the Other Documents to be performed on or after the date of this Amendment.  As to each and every Claim released hereunder, each Releasing Party waives the benefit of each provision of applicable federal or state law (including

without limitation the laws of the state of New York), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.

Each Releasing Party acknowledges that it may hereafter discover facts different from or in addition to those now known or believed to be true with respect to such Claims, and agrees that this instrument shall be and remain effective in all respects notwithstanding any such differences or additional facts.  Each Releasing Party understands, acknowledges and agrees that the release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

(b)         Covenant Not to Sue.  Each Releasing Party hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee above that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by such Releasing Party pursuant to the above release.  Each Releasing Party further agrees that it shall not dispute the validity or enforceability of the Revolving Credit Agreement or any of the Other Documents or any of its obligations thereunder, or the validity, priority, enforceability or the extent of Agent’s Lien on any item of Collateral under the Revolving Credit Agreement or the Other Documents.  If any Releasing Party or any of its respective successors, assigns, or officers, directors, employees, agents or attorneys (solely in their capacities as officers, directors, employees, agents and attorneys), or any Person acting for or on behalf of, or claiming through it violate the foregoing covenant, each Borrower and Guarantor, for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by such Releasee as a result of such violation.

10)      No Waiver; Cumulative Remedies.  No failure to exercise and no delay in exercising, on the part of the Agent or the Lenders, any right, remedy, power or privilege under the Forbearance Agreement, the Revolving Credit Agreement or any Other Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege under this Amendment, the Revolving Credit Agreement or any Other Document preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.  The rights, remedies, powers and privileges of the Agent and the Lenders provided under this Amendment, the Revolving Credit Agreement and the Other Documents are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

11)      Execution in Counterparts.  This Amendment may be executed by one or more of the parties hereto on any number of separate counterparts (including by telecopy or electronic transmission), and all of which counterparts taken together shall be deemed to constitute one and the same instrument.  Each party executing this Amendment represents that such party has the full authority and legal power to do so.

12)      Severability.  Any provision of this Amendment which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any

such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

13)      Indemnity; Governing Law; Jury Trial Waiver.  The provisions of Sections 7.4, 7.12 and 7.13 of the Forbearance Agreement are hereby incorporated by reference, mutatis mutandis, and shall be deemed to be a part hereof as if restated herein in their entirety.
