The Securities will be secured pursuant to the security documents listed on Schedule IV hereto (the “Security Documents”) by a lien on the Collateral (as defined herein).

prior written consent of Credit Suisse; provided, however, that, prior to the completion of the distribution of the Securities by the Initial Purchasers (as determined by Credit Suisse), the Company will not file any document under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Offering Circular unless, prior to such proposed filing, the Company has furnished Credit Suisse (and, upon request, to each of the other Initial Purchasers) with a copy of such document for its review and Credit Suisse has not reasonably objected to the filing of such document. The Company will promptly advise Credit Suisse when any document filed under the Exchange Act that is incorporated by reference in the Disclosure Package or the Final Offering Circular shall have been filed with the Commission.

(c) If at any time prior to the completion of the sale of the Securities by the Initial Purchasers (as determined by Credit Suisse), any event occurs as a result of which the Disclosure Package or the Final Offering Circular, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it should be necessary to amend or supplement the Disclosure Package or the Final Offering Circular to comply with applicable law, the Issuers will (x) if such time is prior to the date that is nine months from the date of the Final Offering Circular, at the Issuers’ expense and (y) if otherwise, at the Initial Purchasers’ expense, promptly (i) notify Credit Suisse of any such event; (ii) subject to the requirements of paragraph (b) of this Section 5, prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or the Final Offering Circular to Credit Suisse and counsel for the Initial Purchasers (and, upon request, to each of the other Initial Purchasers) without charge in such quantities as they may reasonably request.

(e) The Issuers will arrange, upon the request of Credit Suisse, for the qualification of the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as Credit Suisse may designate and will maintain such qualifications in effect so long as required for the sale of the Securities; provided that in no event shall any Issuer be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. The Issuers will promptly advise Credit Suisse of the receipt by any Issuer of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(f) The Initial Purchasers shall have received, by the Closing Date, fully executed copies of Amendment No. 10 to the Revolving Credit Facility, reasonably satisfactory to Initial Purchasers counsel, which amendment shall permit the issuance of the Securities as contemplated in the Disclosure Package and Indenture.

7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Issuers to perform any agreement herein or comply with any provision hereof other than by reason of a default by any Initial Purchaser, the Issuers will reimburse the Initial Purchasers on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution.

(a) The Issuers, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Circular, Disclosure Package, the Final Offering Circular, any Issuer Written Information or any other written information used by or on behalf of the Issuers in connection with the offer or sale of the Securities, or in any amendment or supplement thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Offering Circular, the Disclosure Package, the Final Offering Circular, any Issuer Written Information or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Issuers by or on behalf of the Initial Purchasers specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless each Issuer, each of their directors, each of their officers, and each person who controls such Issuer within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from such Issuer to each Initial Purchaser, but only with reference to written information relating to the Initial Purchasers furnished to such Issuer by or on behalf of the Initial Purchasers specifically for inclusion in the Preliminary Offering Circular, the Disclosure Package, any Issuer Written Information or the Final Offering Circular or in any amendment or supplement thereto. This indemnity agreement will be in addition to any liability that the Initial Purchasers may otherwise have. Each Issuer acknowledges that the statements regarding market-making activities in the seventh paragraph and the eighth and ninth paragraphs under the heading “Plan of Distribution” in the Preliminary Offering Circular and the Final Offering Circular constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Offering Circular, the Disclosure Package, Issuer Written Information or the Final Offering Circular in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize in writing the indemnified party to employ separate counsel at the expense of the indemnifying party; provided, however, the indemnifying party shall not be liable for the fees and expenses of more than one such separate counsel (together with local counsel) in connection with any action or related proceeding in the same jurisdiction. An indemnifying party will not, without the prior written consent of the indemnified parties, which consent shall not be unreasonably withheld, delayed or conditioned, settle, compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuers and each Initial Purchaser severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Issuers and any Initial Purchaser may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuers on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuers and each Initial Purchaser severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuers on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Issuers shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Initial Purchasers shall be

deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuers on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Issuers and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of any Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls an Issuer within the meaning of either the Act or the Exchange Act and each officer and director of an Issuer shall have the same rights to contribution as such Issuer, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default of Initial Purchasers. If any Initial Purchaser or Initial Purchasers default in their obligations to purchase the Notes hereunder and the aggregate principal amount of the Notes that such defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of the Notes, Credit Suisse may make arrangements satisfactory to the Company for the purchase of such Notes by other persons, including any of the Initial Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Initial Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Notes that such defaulting Initial Purchasers agreed but failed to purchase. If any Initial Purchaser or Initial Purchasers so default and the aggregate principal amount of the Notes with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Notes and arrangements satisfactory to Credit Suisse and the Company for the purchase of such Notes by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Initial Purchaser or the Company, except as provided in Section 11. As used in this Agreement, the term “Initial Purchaser” includes any person substituted for an Initial Purchaser under this Section 9. Nothing herein will relieve a defaulting Initial Purchaser from liability for its default.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Initial Purchasers, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in securities generally on the New York Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on such exchange or the Nasdaq National Market; (ii) trading of any securities of the Company shall have been suspended on any exchange or over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Initial Purchasers, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Preliminary Offering Circular and the Final Offering Circular.

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuers or their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Issuers or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Initial Purchasers, will be mailed, delivered or sent by facsimile transmission to c/o Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, New York 10010-3629, Attention: LCD-IBD; or, if sent to the Issuers, will be mailed, delivered or facsimile transmission to (814)  ###-###-#### and confirmed to it at 15 Bradley Street, Warren, Pennsylvania 16365, attention of the Legal Department; provided, however, that any notice to an Initial Purchaser pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Initial Purchaser.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(i) hereof, no other person will have any right or obligation hereunder.

14. Representation of Initial Purchasers. You will act for the several Initial Purchasers in connection with this purchase, and any action under this Agreement taken by you will be binding upon all the Initial Purchasers.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuers and the Initial Purchasers, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

17. No Fiduciary Duty. Each Issuer hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) each Initial Purchaser is acting as principal and not as an agent or fiduciary of the Issuers and (c) the Issuers’ engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, each Issuer agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any Initial Purchaser has advised or is currently advising the Issuers on related or other matters). Each Issuer agrees that it will not claim that any Initial Purchaser has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to such Issuer, in connection with such transaction or the process leading thereto.

18. Waiver of Tax Confidentiality. Notwithstanding anything herein to the contrary, purchasers of the Securities (and each employee, representative or other agent of a purchaser) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of any transaction contemplated herein and all materials of any kind (including opinions or other tax analyses) that are provided to the purchasers of the Securities relating to such U.S. tax treatment and U.S. tax structure, other than any information for which nondisclosure is reasonably necessary in order to comply with applicable securities laws.
