A. Indemnification.

1. Indemnification of Directors and Officers. The Corporation shall indemnify and hold harmless, to the fullest extent permitted by the DGCL, each person (and the heirs, executors or administrators of such person) who was or is a party or is threatened to be made a party to, or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, limited liability company, joint venture, trust or other enterprise. The right to indemnification conferred in this Article VIII shall also include the right to have the Corporation pay directly or cause to be paid directly the expenses incurred in connection with any such proceeding in advance of its final disposition to the fullest extent authorized by the DGCL. The right to indemnification conferred in this Article VIII shall be a contract right.

2. Indemnification of Employees and Agents. The Corporation may, by action of the Board, indemnify the employees and agents of the Corporation to such extent and to such effect as the Board of Directors shall determine to be appropriate and authorized by the DGCL.

3. Insurance. The Corporation shall have the right, power and authority 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, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article VIII and the DGCL.

4. Non-Exclusivity of Rights; Continuation of Rights. The rights and authority conferred in this Article VIII shall not be exclusive of any other right that any person may otherwise have or hereafter acquire.

B. Elimination of Certain Liability of Directors. No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, as the same exists or hereafter may be amended, or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended to authorize the further elimination or limitation of liability of directors, then the liability of a director of the Corporation, in addition to the limitation on personal liability provided herein, shall be limited to the fullest extent permitted by the amended DGCL. Any repeal or modification of this Article VIII by the stockholders of the Corporation shall be prospective only and shall not adversely affect any limitation on the personal liability of a director of the Corporation existing at the time of such repeal or modification.

ARTICLE IX

Meetings of stockholders may be held within or without the State of Delaware, as the Bylaws may provide. Any action required or permitted to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding Common Stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of Common Stock entitled to vote thereon were present and voted, and shall be delivered to the Corporation.

The books of the Corporation may be kept (subject to any provision contained in the DGCL) within or outside of the State of Delaware at such place or places as may be designated from time to time by the Board or in the Bylaws.

ARTICLE X

Neither any contract or other transaction between the Corporation and any other corporation, partnership, limited liability company, joint venture, firm, association, or other entity (an “Entity”), nor any other acts of the Corporation with relation to any other Entity will, in the absence of fraud, to the fullest extent permitted by applicable law, in any way be invalidated or otherwise affected by the fact that any one or more of the directors or officers of the Corporation are pecuniary or otherwise interested in, or are directors, officers, partners, or members of, such other Entity (such directors, officers, and Entities, each a “Related Person”). Any Related Person may be a party to, or may be pecuniary or otherwise interested in, any contract or transaction of the Corporation; provided, however, that the fact that person is a Related Person or is pecuniary or otherwise interested in such contract or transaction is disclosed or is known to the Board or a majority of directors present at any meeting of the Board at which action upon any such contract or transaction is taken. Any director of the Corporation who is also a Related Person or who is pecuniary or otherwise interested in such contract or transaction may be counted in determining the existence of a quorum at any meeting of the Board during which any such contract or transaction is authorized and may vote thereat to authorize any such contract or transaction, with like force and effect as if such person were not a Related Person or were not pecuniary or otherwise interested in such contract or transaction. Any director of the Corporation may vote upon any contract or any other transaction between the Corporation and any subsidiary or affiliated Entity without regard to the fact that such person is also a director, officer, manager, general partner or other fiduciary of such subsidiary or affiliated Entity.

Any contract, transaction or act of the Corporation or of the directors of the Corporation that is ratified at any annual meeting of the stockholders of the Corporation, or at any special meeting of the stockholders of the Corporation called for such purpose, will, insofar as permitted by applicable law, be as valid and as binding as though ratified by every stockholder of the Corporation; provided, however, that any failure of the stockholders to approve or ratify any such contract, transaction or act, when and if submitted, will not be deemed in any way to invalidate the same or deprive the Corporation, its directors, officers or employees, of its or their right to proceed with such contract, transaction or act.

Subject to any express agreement that may from time to time be in effect, (x) any director or officer of the Corporation who is also an officer, director, partner, employee, managing director or other affiliate of either Apollo Management VIII, L.P., on behalf of its investment funds (“Apollo”), or any of its respective affiliates (collectively, the “Managers”) and (y) the Managers and their affiliates, may, and shall have no duty not to, in each case on behalf of the Managers or their affiliates (the persons and entities in clauses (x) and (y), each a “Covered Manager Person”), to the fullest extent permitted by applicable law, (i) carry on and conduct, whether directly, or as a partner in any partnership, or as a member or manager in any limited liability company or as a joint venturer in any joint venture, or as an officer, director or stockholder of any corporation, or as a participant in any syndicate, pool, trust or

association, any business of any kind, nature or description, whether or not such business is competitive with or in the same or similar lines of business as the Corporation, (ii) do business with any client, customer, vendor or lessor of any of the Corporation or its affiliates, and (iii) make investments in any kind of property in which the Corporation may make investments. To the fullest extent permitted by Section 122(17) of the DGCL, the Corporation hereby renounces any interest or expectancy of the Corporation to participate in any business of the Managers or their affiliates, and waives any claim against a Covered Manager Person and shall indemnify a Covered Manager Person against any claim that such Covered Manager Person is liable to the Corporation or its stockholders for breach of any fiduciary duty solely by reason of such person’s or entity’s participation in any such business.

In the event that a Covered Manager Person acquires knowledge of a potential transaction or matter which may constitute a corporate opportunity for both (x) the Covered Manager Person, in his or her Apollo-related capacity, as the case may be, or Apollo or its affiliates, as the case may be, and (y) the Corporation, to the fullest extent permitted by law, the Covered Manager Person shall not have any duty to offer or communicate information regarding such corporate opportunity to the Corporation. To the fullest extent permitted by Section 122(17) of the DGCL, the Corporation hereby renounces any interest or expectancy of the Corporation in such corporate opportunity and waives any claim against each Covered Manager Person and shall indemnify a Covered Manager Person against any claim that such Covered Manager Person is liable to the Corporation or its stockholders for breach of any fiduciary duty solely by reason of the fact that such Covered Manager Person (i) pursues or acquires any corporate opportunity for its own account or the account of any affiliate, (ii) directs, recommends, sells, assigns or otherwise transfers such corporate opportunity to another person or (iii) does not communicate information regarding such corporate opportunity to the Corporation.

Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article X.

This Article X may not be amended, modified or repealed without the prior written consent of each of the Managers.

In the event of a conflict between this Article X and any other Article or provision of this Amended and Restated Certificate of Incorporation, this Article X shall prevail under all circumstances. Notwithstanding anything to the contrary herein, under no circumstances shall any employee of the Corporation or any of its subsidiaries be deemed to be a “Covered Manager Person”, and under no circumstances shall the Corporation waive or renounce any interest or expectancy of the Corporation in, or in being offered any opportunity to participate in, any business opportunities that are presented to any Manager who is also an employee of the Corporation or any of its subsidiaries, irrespective of whether such employee is a director or officer of the Corporation of any of its affiliates.

ARTICLE XI

Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Corporation, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, stockholder, employee or agent of the Corporation to the Corporation or the Corporation’s stockholders, (c) any action asserting a claim arising pursuant to any provision of the DGCL or (d) any action asserting a claim governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article XI.

ARTICLE XII

The Corporation elects not to be governed by Section 203 of the DGCL.
