Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantor hereunder which shall remain absolute and unconditional as described above:

(e)    any transfer of any assets to or from the Company, including without limitation any transfer or purported transfer to the Company from any person, any invalidity, illegality of, or inability to enforce, any such transfer or purported transfer, any consolidation or merger of the Company with or into any person, any change in the ownership of any shares of capital stock of the Company, or any change whatsoever in the objects, capital structure, constitution or business of the Company;

(f)    any default, failure or delay, willful or otherwise, on the part of the Company or any other person to perform or comply with, or the impossibility or illegality of performance by the Company or any other Person of, any term of the Shelf Agreement, the Notes or any other agreement;

(g)    any suit or other action brought by, or any judgment in favor of, any beneficiaries or creditors of, the Company or any other person for any reason whatsoever, including without limitation any suit or action in any way attacking or involving any issue, matter or thing in respect of the Shelf Agreement, the Notes or any other agreement;

(h)    any lack or limitation of status or of power, incapacity or disability of the Company or any trustee or agent thereof; or

(i)    any other thing, event, happening, matter, circumstance or condition whatsoever, not in any way limited to the foregoing.

Section 5.    Reinstatement.

Notwithstanding any provision of the Shelf Agreement to the contrary, the liability of Guarantor hereunder shall be reinstated and revived and the rights of the Holders shall continue if and to the extent that for any reason any payment by or on behalf of Guarantor or Company is rescinded or must

be otherwise restored by the Holders, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, all as though such amount had not been paid. The determination as to whether any such payment must be rescinded or restored shall be made by the Required Holders in their sole discretion; provided, however, that if the Required Holders choose to contest any such matter at the request of Guarantor, Guarantor agrees to indemnify and hold harmless the holders of the Notes from all costs and expenses (including, without limitation, reasonable attorneys’ fees) of such litigation. To the extent any payment is rescinded or restored, Guarantor’s obligations hereunder shall be revived in full force and effect without reduction or discharge for that payment.

Section 6.    No Waiver; Amendments.

No failure on the part of any holder of any Note to exercise, no delay in exercising and no course of dealing with respect to, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. This Guaranty may not be amended or modified except by written agreement between Guarantor and the Required Holders, except that any amendment or modification to Section 1 shall require the consent of each Holder.

Section 7.    Compromise and Settlement.

No compromise, settlement, release, renewal, extension, indulgence, change in, waiver or modification of any of the Obligations or the release or discharge of Company from the performance of any of the Obligations shall release or discharge Guarantor from this Guaranty or the performance of the obligations hereunder.

All representations and warranties contained herein shall survive the execution and delivery of this Guaranty, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Guarantor pursuant to this Guaranty shall be deemed representations and warranties of the Guarantor under this Guaranty.

Section 10.    Severability.

Section 11.    Subordination of Indebtedness.

Any indebtedness or other obligation of Company now or hereafter held by or owing to Guarantor is hereby subordinated in time and right of payment to all obligations of Company to the Holders, except as such indebtedness or other obligation is expressly permitted to be paid under the Shelf Agreement; and such indebtedness of Company to Guarantor is assigned to the Holders as security for this Guaranty, and if such Holders so request shall be collected, enforced and received by Guarantor in trust for the Holders and to be paid over to such holders on account of the Guaranteed Obligations of Company to such Holders, but without reducing or affecting in any manner the liability of Guarantor under the other provisions of this Guaranty. Any notes now or hereafter evidencing such indebtedness of Company to Guarantor shall be marked with a legend that the same are subject to this Guaranty and shall be delivered to the Holders. Nothing in this Section 11 shall prohibit the Company from making, or Guarantor from accepting, any scheduled payment of principal or interest on any subordinated indebtedness at a time when no Default or Event of Default has occurred and is continuing.

Section 12.    Payment of Expenses.

Guarantor shall pay, promptly on demand, all Expenses incurred by any Holder in defending and/or enforcing this Guaranty. For purposes hereof, “Expenses” shall mean costs and expenses (including reasonable fees and disbursements of any law firm or other external counsel and the allocated

cost of internal legal services and all disbursements of internal counsel) for defending and/or enforcing this Guaranty (including those incurred in connection with appeals or proceedings by or against Guarantor under the United States Bankruptcy Code, or any other bankruptcy or insolvency law, including assignments for the benefit of creditors, compositions, extensions generally with Guarantor’s creditors, or proceedings seeking reorganization, arrangement, or other relief).

This Guaranty shall be binding upon and inure to the benefit of Guarantor and the Holders and their respective successors and assigns, except that Guarantor shall not have the right to assign Guarantor’s rights hereunder or any interest herein without the prior written consent of the Holders, and such direction may be granted or withheld in Holders’ sole discretion. Any such purported assignment by Guarantor without the Holders’ written consent shall be void.

Section 14.    Governing Law; Jurisdiction and Process; Waiver of Jury Trial.

(a)    This Guaranty shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the Commonwealth of Virginia excluding choice‑of‑law principles of the law of such Commonwealth that would permit the application of the laws of a jurisdiction other than such Commonwealth.

(b)    The Guarantor irrevocably submits to the non-exclusive jurisdiction of any Virginia State or federal court sitting in the city of Roanoke, over any suit, action or proceeding arising out of or relating to this Guaranty. To the fullest extent permitted by applicable law, the Guarantor irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

The Guarantor agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service.

(d)    Nothing in this Section 14 shall affect the right of any Holder to serve process in any manner permitted by law, or limit any right that the holders of any of the Notes may

have to bring proceedings against the Guarantor in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.
