NINTH: The Corporation reserves the right to amend, alter or repeal any provision contained in this Certificate of Incorporation in the manner now or hereafter prescribed by statute, and all rights of stockholders herein are subject to this reservation.

TENTH: A director of this Corporation shall not be personally liable to this Corporation or its shareholders for monetary damages for a breach of the director’s fiduciary duty, except in the event of any of the following:

(a)

A breach of the director’s duty of loyalty to the Corporation or its shareholders;

(b)

Acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

(c)

A violation of Section 174 of the General Corporation Law of the State of Delaware; and

(d)

A transaction from which the director derived an improper personal benefit.

ELEVENTH:

(a) Right to Indemnification . Except as prohibited by law, every director and officer of the Corporation shall be entitled as of right to be indemnified by the Corporation against all expenses and liability (as those terms are defined below in this Section) incurred by such person in connection with any actual or threatened claim, action, suit or proceeding, whether civil, criminal, administrative, investigative or other, or whether brought by or against such person or by or in the right of the Corporation or otherwise, in which such person may be involved, as a party or otherwise, by reason of such person being or having been a director or officer of the Corporation or a subsidiary of the Corporation or by reason of the fact that such person is or was serving at the request of the Corporation as a director, officer, employee, fiduciary or other representative of another corporation, partnership, joint venture, trust, employee benefit plan or other entity (such claim, action, suit or proceeding hereinafter being referred to as an “Action”); provided, however, that no such right to indemnification shall exist with respect to an Action brought by an indemnitee (as defined below) against the Corporation (an “Indemnitee Action”) except as provided in the last sentence of this Section. Persons who are not directors or officers of the Corporation may be similarly indemnified in respect of service to the Corporation or a subsidiary of the Corporation or to another such entity at the request of the Corporation to the extent the Board of Directors of the Corporation at any time designates any of such persons as entitled to the benefits of this Article. As used in this Article, “indemnitee” includes each director and officer of the Corporation and each other person designated by the Board of Directors of the Corporation as entitled to the benefits of this Article; “expenses” means all expenses actually and reasonably incurred, including fees and expenses of counsel selected by an indemnitee; and “liability” means all liability incurred, including the amounts of any judgments, excise taxes, fines or penalties and any amounts paid in settlement. An indemnitee shall be entitled to be indemnified pursuant to this Article against expenses incurred in connection with an Indemnitee Action if (i) the Indemnitee Action is instituted under Section

Page 2

(c) of this Article and the indemnitee is successful in whole or in part in such Indemnitee Action, (ii) the indemnitee is successful in whole or in part in another Indemnitee Action for which expenses are claimed or (iii) the indemnification for expenses is included in a settlement of, or is awarded by a court in, such other Indemnitee Action.

(b) Right to Advancement of Expenses . Every indemnitee shall be entitled as of right to have the expenses of the indemnitee in defending any Action or in bringing and pursuing any Indemnitee Action under Section (c) of this Article paid in advance by the Corporation prior to final disposition of the Action or Indemnitee Action, provided that the Corporation receives a written undertaking by or on behalf of the indemnitee to repay the amount advanced if it should ultimately be determined that the indemnitee is not entitled to be indemnified for the expenses.

(c) Right of Indemnitee to Bring Action . If a written claim for indemnification under Section (a) of this Article or for advancement of expenses under Section (b) of this Article is not paid in full by the Corporation within 30 days after the claim has been received by the Corporation, the indemnitee may at any time thereafter bring an Indemnitee Action to recover the unpaid amount of the claim and, if successful in whole or in part, the indemnitee shall also be entitled to be paid the expense of bringing and pursuing such Indemnitee Action. The only defense to an Indemnitee Action to recover on a claim for indemnification under Section (a) of this Article shall be that the conduct of the indemnitee was such that, under Delaware law, the Corporation is prohibited from indemnifying the indemnitee for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel and stockholders) to have made a determination prior to the commencement of such Indemnitee Action that indemnification of the indemnitee is proper in the circumstances, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or stockholders) that the conduct of the indemnitee was such that indemnification is prohibited by Delaware law, shall be a defense to such Indemnitee Action or create a presumption that the conduct of the indemnitee was such that indemnification is prohibited by Delaware law. The only defense to an Indemnitee Action to recover on a claim for advancement of expenses under Section (b) of this Article shall be failure by the indemnitee to provide the undertaking required by Section (b) of this Article.

(d) Funding and Insurance . The Corporation may create a trust fund, grant a security interest, cause a letter of credit to be issued or use other means (whether or not similar to the foregoing) to ensure the payment of all sums required to be paid by the Corporation to effect indemnification as provided in this Article. The Corporation may purchase and maintain insurance to protect itself and any indemnitee against any expenses or liability incurred by the indemnitee in connection with any Action, whether or not the Corporation would have the power to indemnify the indemnitee against the expenses or liability by law or under the provisions of this Article.

(e) Non-Exclusivity; Nature and Extent of Rights . The rights to indemnification and advancement of expenses provided for in this Article shall (i) not be deemed exclusive of any other rights, whether now existing or hereafter created, to which any indemnitee may be entitled under any agreement, provision in the Certificate of Incorporation or By-Laws of

Page 3

the Corporation, vote of stockholders or disinterested directors or otherwise, (ii) be deemed to create contractual rights in favor of each indemnitee who serves at any time while this Article is in effect (and each such indemnitee shall be deemed to be serving in reliance on the provisions of this Article), (iii) continue as to each indemnitee who has ceased to have the status pursuant to which the indemnitee was entitled or was designated as entitled to indemnification under this Article and inure to the benefit of the heirs and legal representatives of each indemnitee and (iv) be applicable to Actions commenced after this Article becomes effective, whether arising from acts or omissions occurring before or after this Article becomes effective. Any amendment or repeal of this Article or adoption of any By-Law of this Corporation or other provision of the Certificate of Incorporation of this Corporation that has the effect of limiting in any way the rights to indemnification or advancement of expenses provided for in this Article shall operate prospectively only and shall not affect any action taken, or any failure to act, by an indemnitee prior to such amendment, repeal, By-Law or other provision becoming effective.

(f) Partial Indemnity . If an indemnitee is entitled under any provision of this Article to indemnification by the Corporation for some or a portion of the expenses or liability incurred by the indemnitee in the preparation, investigation, defense, appeal or settlement of any Action or Indemnitee Action but not, however, for the total amount thereof, the Corporation shall indemnify the indemnitee for the portion of such expenses or liability to which the indemnitee is entitled.

THE UNDERSIGNED, being the incorporator above named for the purposes of forming a corporation pursuant to the General Corporation Law of the State of Delaware, has signed this instrument the 20 ^th day of November, 2009 and does thereby acknowledge that it is his act and deed and that the facts stated therein are true.

Section 6. Quorum and Transaction of Business . A majority of the whole authorized number of directors shall constitute a quorum for the transaction of business, except that a majority of the directors in office shall constitute a quorum for filling a vacancy on the board. Whenever less than a quorum is present at the time and place appointed for any meeting of the board, a majority of those present may adjourn the meeting from time to time, until a quorum shall be present.

Section 8. Regular Meetings . Regular meetings of the board of directors shall be held at such times and places, within or without the State of Delaware, as the board of directors may, by resolution, from time to time determine.

Section 10. Notice of Annual or Special Meetings . Notice of the time and place of each annual or special meeting shall be given to each director by the secretary or by the person or persons calling such meeting. Such notice need not specify the purpose or purposes of the meeting and may be given in any manner or method and at such time so that the director receiving it may have reasonable opportunity to attend the meeting. Such notice shall, in all events, be deemed to have been properly and duly given if mailed at least forty-eight hours prior to the meeting and directed to the residence of each director as shown upon the secretary’s records. The giving of notice shall be deemed to have been waived by any director who shall attend and participate in such meeting and may be waived, in writing, by any director either before or after such meeting.

Section 11. Compensation . The directors, as such, shall be entitled to receive such reasonable compensation, if any, for their services as may be fixed from time to time by

-3-

resolution of the board, and expenses of attendance, if any, may be allowed for attendance at each annual, regular or special meeting of the board. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 2. Meetings of Executive Committee . Subject to the provisions of these By-laws, the executive committee shall fix its own rules of procedure and shall meet as provided by such rules or by resolutions of the board of directors, and it shall also meet at the call of the chairman of the board, the chief executive officer, the president, the chairman of the executive committee or any two members of the committee. Unless otherwise provided by such rules or by such resolutions, the provisions of Section 10 of Article II relating to the notice required to be given of meetings of the board of directors shall also apply to meetings of the members of the executive committee. A majority of the executive committee shall be necessary to constitute a quorum. The executive committee may act in writing without a meeting, but no such action of the executive committee shall be effective unless concurred in by all members of the committee.

Section 3. Other Committees . The board of directors may by resolution provide for such other standing or special committees as it deems desirable, and discontinue the same at its pleasure. Each such committee shall have such powers and perform such duties, not inconsistent with law, as may be delegated to it by the board of directors.

ARTICLE VI

Indemnification and Insurance

-6-

Section 1. Indemnification in Non-Derivative Actions . The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, manager, employee or agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Section 2. Indemnification in Derivative Actions . The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, manager, employee or agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 3. Indemnification as a Matter of Right . To the extent that a director, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article VI, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith.

Section 4. Determination of Conduct . Any indemnification under Sections 1 and 2 of this Article VI (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 and 2 of this Article VI. Such determination shall be made (1) by the board of directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if

-7-

obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders.

Section 5. Advance Payment of Expenses . Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this section.

Section 6. Nonexclusivity . The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VI shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office.

Section 7. Liability Insurance . The Corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, manager, employee or agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify him against such liability under the provisions of this section.

Section 8. Corporation . For purposes of this Article VI, references to “the Corporation” shall include, in addition to the resulting entity, any constituent entity (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, members, managers and employees or agents, so that any person who is or was a director, officer, member, manager, employee or agent of such constituent entity, or is or was serving at the request of such constituent entity as a director, officer, member, manager, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article VI with respect to the resulting or surviving entity as he would have with respect to such constituent entity if its separate existence had continued.

Section 9. Employee Benefit Plans . For purposes of this Article VI, references to any “other enterprise” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article VI.

Section 10. Continuation . The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VI shall, unless otherwise provided when

-8-

authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

ARTICLE VII

Certificates for Shares

Section 1. Form and Execution . Certificates for shares, certifying the number of full-paid shares owned, shall be issued to each stockholder in such form as shall be approved by the board of directors. Such certificates shall be signed by the chairman or vice-chairman of the board of directors, the chief executive officer or the president or a vice president and by the secretary or an assistant secretary or the treasurer or an assistant treasurer; provided, however, that the signatures of any of such officers and the seal of the Corporation upon such certificates may be facsimiles, engraved, stamped or printed. If any officer or officers who shall have signed, or whose facsimile signature shall have been used, printed or stamped on any certificate or certificates for shares, shall cease to be such officer or officers, because of death, resignation or otherwise, before such certificate or certificates shall have been delivered by the Corporation, such certificate or certificates shall nevertheless be as effective in all respects as though signed by a duly elected, qualified and authorized officer or officers, and as though the person or persons who signed such certificate or certificates, or whose facsimile signature or signatures shall have been used thereon, had not ceased to be an officer or officers of the Corporation.

Section 2. Registration of Transfer . Any certificate for shares of the Corporation shall be transferable in person or by attorney upon the surrender thereof to the Corporation or any transfer agent therefor (for the class of shares represented by the certificate surrendered) properly endorsed for transfer and accompanied by such assurances as the Corporation or such transfer agent may require as to the genuineness and effectiveness of each necessary endorsement.

Section 3. Lost, Destroyed or Stolen Certificates . A new share certificate or certificates may be issued in place of any certificate theretofore issued by the Corporation which is alleged to have been lost, destroyed or wrongfully taken upon (i) the execution and delivery to the Corporation by the person claiming the certificate to have been lost, destroyed or wrongfully taken of an affidavit of that fact, specifying whether or not, at the time of such alleged loss, destruction or taking, the certificate was endorsed, and (ii) the furnishing to the Corporation of indemnity and other assurances, if any, satisfactory to the Corporation and to all transfer agents and registrars of the class of shares represented by the certificate against any and all losses, damages, costs, expenses or liabilities to which they or any of them may be subjected by reason of the issue and delivery of such new certificate or certificates or in respect of the original certificate.

Section 4. Registered Stockholders . A person in whose name shares are of record on the books of the Corporation shall conclusively be deemed the unqualified owner and holder thereof for all purposes and to have capacity to exercise all rights of ownership. Neither the Corporation nor any transfer agent of the Corporation shall be bound to recognize any equitable interest in or claim to such shares on the part of any other person, whether disclosed upon such certificate or otherwise, nor shall they be obliged to see to the execution of any trust or obligation.

B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement or the Guarantee and Collateral Agreement, as applicable.

C. The Grantors have entered into the Guarantee and Collateral Agreement in order to induce the Lenders to make Loans and the Issuing Bank to issue Letters of Credit. Section 7.16 of the Guarantee and Collateral Agreement provides that additional Domestic Subsidiaries of the Loan Parties may become Subsidiary Guarantors and Grantors under the Guarantee and Collateral Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary (a “ New Subsidiary ”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Subsidiary Guarantor and Grantor under the Guarantee and Collateral Agreement in order to induce the Lenders to make additional Loans and the Issuing Bank to issue additional Letters of Credit and as consideration for Loans previously made and Letters of Credit previously issued.

Accordingly, the Agent and the New Subsidiary agree as follows:

SECTION 1. In accordance with Section 7.16 of the Guarantee and Collateral Agreement, the New Subsidiary by its signature below becomes a Grantor and Subsidiary Guarantor under the Guarantee and Collateral Agreement with the same force and effect as if originally named therein as a Grantor and Subsidiary Guarantor and the New Subsidiary hereby (a) agrees to all the terms and provisions of the Guarantee and Collateral Agreement applicable to it as a Grantor and Subsidiary Guarantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor and Subsidiary Guarantor thereunder are true and correct in all material respects on and as of the date hereof. In furtherance of the foregoing, the New Subsidiary, as

security for the payment and performance in full of the Secured Obligations (as defined in the Guarantee and Collateral Agreement), does hereby create and grant to the Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Guarantee and Collateral Agreement) of the New Subsidiary.
