OR, AT ITS OPTION, IN ITS OWN NAME, COUPLED WITH AN INTEREST, TO COLLECT, RECEIVE, RECEIPT FOR, CREATE, PREPARE, COMPLETE, EXECUTE, ENDORSE, DELIVER, AND FILE ANY AND ALL INSURANCE APPLICATIONS, REMITTANCES, INSTRUMENTS, DOCUMENTS, CHATTEL PAPER, AND OTHER WRITINGS, TO GRANT AN EXTENSION TO, COMPROMISE, SETTLE, WAIVE, NOTIFY, AMEND, ADJUST, CHANGE, AND RELEASE ANY OBLIGATION OF ANY ACCOUNT GRANTOR, OBLIGOR, INSURER, OR OTHER PERSON PERTAINING TO ANY COLLATERAL, AND TAKE ANY OTHER ACTION DEEMED BY SECURED PARTY TO BE NECESSARY OR DESIRABLE TO ESTABLISH, PERFECT, PROTECT, OR ENFORCE THE SECURED PARTY'S INTEREST IN THE COLLATERAL. Grantor shall execute FSA/CCC Power of Attorney

forms and any other documents required to enable Secured Party to execute any and all documents necessary for application for, compliance or reporting of necessary information for all FSA/CCC programs. Secured Party has no duty to exercise any of the authority granted in this paragraph. Secured Party shall not be liable for any act or failure to act in connection with the collection of or the preservation of any rights with respect to the Collateral described in this paragraph.

(a)Grantor hereby acknowledges Lender has entered into a collateral agency agreement between the Secured Parties (the “Collateral Agency Agreement”) which, as amended, modified, or restated, permits Lender to act as a Collateral Agent in servicing the applicable Loan.

(b)The MCA, the other Transaction Documents, and each other agreement or instrument made or entered into in connection with each of the Secured Obligations (collectively, the “Secured Obligation Documents”), collectively: (i) represent the sum of the understandings and agreements between Collateral Agent, Secured Parties, and Grantor concerning this credit; (ii) replace any prior oral or written agreements between Collateral Agent, Secured Parties, and Grantor concerning this credit; and (iii) are intended by Collateral Agent, Secured Parties, and Grantor as the final, complete and exclusive statement of the terms agreed to by them. The Secured Obligation Documents also grant further rights to Collateral Agent and Secured Parties, and contain further agreements and affirmative and negative covenants by Grantor which apply to this Master Security Agreement and to the Collateral.

(c)Each waiver by Collateral Agent or Secured Parties must be in writing, and no waiver is to be construed as a continuing waiver. No waiver is to be implied from any delay or failure by Collateral Agent or Secured Parties to take action on account of any default of Grantor. Consent by Collateral Agent or Secured Parties to any act or omission by Grantor must not be construed as a consent to any other or subsequent act or omission or waiver of the requirement for Collateral Agent’s or Secured Parties’ consent to be obtained in any future or other instance. The exercise by Collateral Agent or Secured Parties of any right or remedy under this Master Security Agreement or the other Secured Obligation Documents or under Applicable Law, shall not: cure or waive a breach, Event of Default or Notice of default under this Master Security Agreement or invalidate any act performed pursuant to any such default or Notice; or nullify the effect of any notice of default or sale (unless all Secured Obligations then due have been paid and performed and all other defaults under the Secured Obligation Documents, including any Hedging Agreements, have been cured); or impair the security of this Master Security Agreement; or prejudice Collateral Agent or Secured Parties, or any receiver appointed in accordance with this Master Security Agreement, in the exercise of any right or remedy afforded any of them under this Master Security Agreement; or be construed as an affirmation by Collateral Agent or Secured Parties of any tenancy, lease or option, or a subordination of the Lien of this Master Security Agreement.

(d)Grantor waives all rights, legal and equitable, it may now or hereafter have to require marshaling of assets or to require upon foreclosure sales of assets in a particular order. Each successor and assign of Grantor, including any holder of a Lien subordinate to this Master Security Agreement, by acceptance of its interest or Lien agrees that it shall be bound by the above waiver, as if it had given the waiver itself.

(e)If Grantor consists of more than one Person, each Grantor (a) acknowledges that this Master Security Agreement is the independent and several obligation of each Grantor and may be enforced against each Grantor separately, whether or not enforcement of any right or remedy hereunder has been sought against any other Grantor; and (b) agrees that its liability hereunder and under any other Secured Obligation Document shall be absolute, unconditional, continuing and irrevocable. GRANTOR EXPRESSLY WAIVES ANY REQUIREMENT THAT COLLATERAL AGENT OR SECURED PARTIES EXHAUST ANY RIGHT, POWER OR REMEDY AND PROCEED AGAINST THE OTHER GRANTORS UNDER THIS MASTER SECURITY AGREEMENT, OR ANY OTHER SECURED OBLIGATION DOCUMENTS, OR AGAINST ANY OTHER PERSON UNDER ANY GUARANTY OF, OR SECURITY FOR, ANY OF THE SECURED OBLIGATIONS.

(f)If Grantor is comprised of multiple Persons, any Person comprising Grantor is hereby authorized to bind all Parties comprising Grantor. Collateral Agent and Secured Parties may, at any time and without Notice, waive any prior requirement that requests, authorizations, or other actions be taken only by a Designated Person.

(g)This Master Security Agreement shall inure to the benefit of and shall be binding upon the Parties and their respective successors and assigns; provided that Grantor shall not assign its rights or obligations hereunder without Secured Parties’ consent. However, this Paragraph does not waive the provisions of Section 5(h) of this Master Security Agreement; and Grantor shall not assign its rights or obligations hereunder without the consent of Collateral Agent and Secured Parties. Collateral Agent and Secured Parties may transfer all or any portion of its rights under the Secured Obligation Documents to any other Person. Collateral Agent and Secured Parties may disclose to any actual or proposed transferee any information that Grantor has delivered to Collateral Agent or Secured Parties in connection with the negotiation of this Master Security Agreement or pursuant to the Secured Obligation Documents; and Grantor shall cooperate fully with Collateral Agent and Secured Parties in providing that information to any actual or proposed transferee. Any individual signing this Master Security Agreement does so on his or her own behalf and on behalf of his or her marital community, and agrees that recourse may be had against community assets and against his or her separate property for the satisfaction of all indebtedness, liabilities and obligations of Indemnitor under this Master Security Agreement.

(h)All rights and remedies under this Master Security Agreement and the Secured Obligation Documents are cumulative, and the exercise of any one or more of them does not constitute an election of remedies.

(i)Any provision of any Secured Obligation Document which is prohibited or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions of that Secured Obligation Document or affecting the validity or enforceability of that provision in any other jurisdiction; except that if such provision relates to the payment of any monetary sum, then Collateral Agent may, at its option, declare all Secured Obligations immediately due and payable.

(j)This Master Security Agreement may not be amended, changed, modified, altered, or terminated without the prior written consent of Collateral Agent and Secured Parties.

(k)This Master Security Agreement shall be governed exclusively by the applicable laws of the State of Kentucky (the “Governing Law State”) without regard or reference to its conflict of laws principles. Grantor understands that the laws of the Governing Law State may differ from the

laws of the State where Grantor resides or otherwise is located or where the Collateral is located. However, Grantor understands, agrees and acknowledges that (a) this Master Security Agreement and the Secured Obligation Documents have significant and substantial contacts with the Governing Law State,

(b) it is convenient to Grantor and Lender to select the law of the Governing Law State to govern this Master Security Agreement and the transactions evidenced hereby, (c) the transactions evidenced by this Master Security Agreement bear a reasonable connection to the laws of the Governing Law State, (d) the choice of the internal laws of the Governing Law State was made for good and valid reasons, and (e) the choice of the Governing Law State constitutes good and valuable consideration for Secured Parties to enter into the Secured Obligation Documents and Secured Parties have entered into the Secured Obligation Documents in reliance on this choice.

(l)GRANTOR IRREVOCABLY AGREES THAT, AT THE OPTION OF COLLATERAL AGENT, ALL ACTIONS, PROCEEDINGS OR COUNTERCLAIMS ARISING OUT OF OR RELATING TO THIS MASTER SECURITY AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT WILL BE LITIGATED IN IN ANY CIRCUIT COURT OR UNITED STATES DISTRICT COURT OF THE GOVERNING LAW STATE (AS DEFINED IN SECTION 12.09 OF THE MCA). GRANTOR IRREVOCABLY CONSENTS TO SERVICE, JURISDICTION, AND VENUE OF THOSE COURTS FOR ALL SUCH ACTIONS, PROCEEDINGS AND COUNTERCLAIMS AND WAIVES ANY OTHER VENUE TO WHICH IT MIGHT BE ENTITLED BY VIRTUE OF DOMICILE, HABITUAL RESIDENCE, OR OTHERWISE.

(m)This Master Security Agreement may be executed in counterparts, each of which will be an original and all of which together are deemed one and the same instrument.

(n)Collateral Agent is authorized to execute any other documents or take any other actions necessary to effectuate this Master Security Agreement and the consummation of the transactions contemplated herein.

(o)Collateral Agent is authorized to file in any Uniform Commercial Code jurisdiction, any such financing statement or amendment as Collateral Agent deems necessary or desirable to perfect its security interest, including but not limited, to a financing statement or amendment indicating the collateral as “all assets,” “all personal property,” or “all personal property and fixtures” of Grantor.

(p)Collateral Agent and Secured Parties are authorized to order a credit report and verify all other credit information, including past and present loans and standard references from time to time to evaluate the creditworthiness of Grantor. Without limitation, a copy of the consent for release of information, general authorization or similar document on file with Collateral Agent or Secured Parties shall authorize third Persons to provide the information requested from time to time.

(q)Each Party has participated in negotiating and drafting this Master Security Agreement, so if an ambiguity or a question of intent or interpretation arises, this Master Security Agreement is to be construed as if the Parties had drafted it jointly, as opposed to being construed against a Party because it was responsible for drafting one or more provisions of this Master Security Agreement.

(r)GRANTOR, AND BY ACCEPTANCE HEREOF, COLLATERAL AGENT (A) COVENANTS AND AGREES NOT TO ELECT A TRIAL BY JURY IN ANY ACTION OR PROCEEDING FOR THE RESOLUTION OF ANY CONTROVERSY OR CLAIM THAT ARISES OUT OF OR RELATES TO: (I) THIS MASTER SECURITY AGREEMENT; OR (II) ANY SECURED OBLIGATION DOCUMENT, WHETHER ARISING IN CONTRACT, TORT OR BY STATUTE (INDIVIDUALLY AND COLLECTIVELY, A “CONTROVERSY OR CLAIM”); AND, (B) TO THE EXTENT PERMITTED BY APPLICABLE LAW, WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY CONTROVERSY OR CLAIM TO THE EXTENT SUCH RIGHT EXISTS NOW OR IN THE FUTURE. THE PROVISIONS OF THIS SECTION ARE GIVEN KNOWINGLY AND VOLUNTARILY; AND ARE A MATERIAL INDUCEMENT FOR THE SECURED PARTIES ENTERING INTO THE SECURED OBLIGATION DOCUMENTS.
