ARTICLE III

MEMBERSHIP

Section 3.1 Membership Interests; Additional Members.

Holdings is the sole initial Member of the Company as reflected in Exhibit A attached hereto.  Additional Persons may be admitted to the Company as Members, and Membership Interests may be issued, on such terms and conditions as the existing Members, voting as a single class, may determine at the time of admission.  The terms of admission or issuance must specify the Sharing Ratios applicable thereto and may provide for the creation of different classes or groups of Members or Membership Interests having different (including senior) rights, powers and duties.  The Members may reflect the creation of any new class or group in an amendment to this Agreement, indicating the different rights, powers and duties, and such an amendment shall be approved and executed by the Members in accordance with the terms of this Agreement.  Any such admission shall be effective only after such new Member has executed and delivered to the Members and the Company an instrument containing the notice address of the new Member, the new Member’s ratification of this Agreement and agreement to be bound by it.

Section 3.2 Access to Information.

Each Member shall be entitled to receive any information that it may request concerning the Company for any purpose reasonably related to such Member’s interest in the Company; provided, however, that this Section 3.2 shall not obligate the Company to create any information that does not already exist at the time of such request (other than to convert existing information from one medium to another, such as providing a printout of information that is stored in a computer database).  Each Member shall also have the right, upon reasonable notice, and at all reasonable times during usual business hours to inspect the properties of the Company and to audit, examine and make copies of the books of account and other records of the Company for any purpose reasonably related to such Member’s interest in the Company.  Such right may be

(b) The Company and the Members agree that the rights, duties and obligations of the Members in their capacities as members of the Company are only as set forth in this Agreement and as otherwise arise under the Act.  Furthermore, the Members agree that, to the fullest extent permitted by Applicable Law, the existence of any rights of a Member, or the exercise or forbearance from exercise of any such rights, shall not create any duties or obligations of the Member in its capacity as a member of the Company, nor shall such rights be construed to enlarge or otherwise to alter in any manner the duties and obligations of such Member.

Section 3.4 Withdrawal.

A Member does not have the right or power to Withdraw.

Section 3.5 Meetings.

A meeting of the Members may be called at any time at the request of any Member.

Section 3.7 Conference Telephone Meetings.

Any Member may participate in a meeting of the Members by means of conference telephone or similar communications equipment or by such other means by which all Persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting.

ARTICLE IV

OF MEMBERSHIP INTERESTS

Section 4.1 Assignment; Admission of Assignee as a Member.

Subject to this Article IV, a Member may assign in whole or in part its Membership Interests.  An Assignee has the right to be admitted to the Company as a Member, with the Membership Interests (and attendant Sharing Ratio) so transferred to such Assignee, only if (a) the Member making the Disposition (a “Disposing Member”) has granted the Assignee either (i) all, but not less than all, of such Disposing Member’s Membership Interests or (ii) the express right to be so admitted and (b) such Disposition is effected in strict compliance with this Article IV.  If a Member transfers all of its Membership Interest in the Company pursuant to this Article IV, such admission shall be deemed effective immediately prior to the transfer and, immediately upon such admission, the transferor Member shall cease to be a member of the Company.

Any Disposition of Membership Interests and any admission of an Assignee as a Member shall also be subject to the following requirements, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with:

(a) Payment of Expenses.  The Disposing Member and its Assignee shall pay, or reimburse the Company for, all reasonable costs and expenses incurred by the Company in connection with the Disposition and admission of the Assignee as a Member.

(b) No Release.  No Disposition of Membership Interests shall effect a release of the Disposing Member from any liabilities to the Company or the other Members arising from events occurring prior to the Disposition, except as otherwise may be provided in any instrument or agreement pursuant to which a Disposition of Membership Interests is effected.

(c) Agreement to be Bound.  The Assignee shall execute a counterpart to this Agreement or other instrument by which such Assignee agrees to be bound by this Agreement.

If the Company does not have sufficient cash to pay its obligations, any Member(s) that may agree to do so may advance all or part of the needed funds to or on behalf of the Company. Any advance described in this Section 5.3 will constitute a loan from the Member to the Company, will bear interest at a lawful rate determined by the Members from the date of the advance until the date of payment and will not be a Capital Contribution.

Section 5.4 Return of Contributions.

Except as expressly provided herein, no Member is entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its capital account or its Capital Contributions.  An unreturned Capital Contribution is not a liability of the Company or of any Member.  A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contributions.

All Membership Interests issued pursuant to, and in accordance with, the requirements of this Article V shall be fully paid and non-assessable Membership Interests, except as such non-assessability may be affected by Sections 18-303, 18-607 and 18-804 of the Act.

(b) To the fullest extent permitted by Applicable Law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 9.1(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 9.1, the Indemnitee is not entitled to be indemnified upon receipt by the Company of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 9.1.

(c) The indemnification provided by this Section 9.1 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

20

(d) The Company may purchase and maintain (or reimburse its Affiliates for the cost of) insurance on behalf of the Indemnitees, the Company and its Affiliates and such other Persons as the Company shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 9.1, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to Applicable Law shall constitute “fines” within the meaning of Section 9.1; and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Company.

(f) In no event may an Indemnitee subject the Members to personal liability by reason of the indemnification provisions set forth in this Agreement.

(h) The provisions of this Section 9.1 are for the benefit of the Indemnitees, their heirs, successors, assigns, executors and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(i) No amendment, modification or repeal of this Section 9.1 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Company, nor the obligations of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 9.1 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

(j) TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AND SUBJECT TO SECTION 9.1(a), THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 9.1 ARE INTENDED BY THE PARTIES TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT.

(b) Subject to any limitations set forth in Article VII and Article VIII, the Board and any committee thereof may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through the Company’s Officers or agents, and neither the Board nor any committee thereof shall be responsible for any misconduct or negligence on the part of any such Officer or agent appointed in good faith by the Board.

(c) Except as expressly set forth in this Agreement, no Member or any other Indemnitee shall have any duties or liabilities, including fiduciary duties, to the Company or any Member, notwithstanding any duty otherwise existing at law or in equity, and the provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of the Members or any other Indemnitee otherwise existing under Applicable Law or in equity, are agreed by the Members to replace such other duties and liabilities of the Members and such other Indemnitee.

(d) No amendment, modification or repeal of this Section 9.2 or any provision hereof shall in any manner affect the limitations on the liability of any Indemnitee under this Section 9.2 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Subject to compliance with Section 7.1(d), the Company may merge or consolidate with one or more domestic or foreign corporations, limited liability companies, statutory trusts or associations, real estate investment trusts, common law trusts or unincorporated businesses, including a partnership (whether general or limited (including a limited liability partnership)), or convert into any such domestic or foreign entity, pursuant to a written agreement of merger or consolidation (“Merger Agreement”) or a written plan of conversion (“Plan of Conversion”), as the case may be, in accordance with this Article 13.  The surviving entity to any such merger, consolidation or conversion is referred to herein as the “Surviving Business Entity.”

Section 13.2 Procedure for Merger, Consolidation or Conversion.

(a) The merger, consolidation or conversion of the Company pursuant to this Article 13 requires the prior approval of a majority of the Board and compliance with Section 13.3.

(b) If the Board shall determine to consent to a merger or consolidation, the Board shall approve the Merger Agreement, which shall set forth:

(i) the names and jurisdictions of formation or organization of each of the business entities proposing to merge or consolidate;

(ii) the name and jurisdiction of formation or organization of the Surviving Business Entity that is to survive the proposed merger or consolidation;

(iii) the terms and conditions of the proposed merger or consolidation;

(iv) the manner and basis of exchanging or converting the equity securities of each constituent business entity for, or into, cash, property or interests, rights, securities or obligations of the Surviving Business Entity; and (A) if any general or limited partner interests, securities or rights of any constituent business entity are not to be exchanged or

25

converted solely for, or into, cash, property or general or limited partner interests, rights, securities or obligations of the Surviving Business Entity, the cash, property or interests, rights, securities or obligations of any general or limited partnership, corporation, trust, limited liability company, unincorporated business or other entity (other than the Surviving Business Entity) which the holders of such general or limited partner interests, securities or rights are to receive in exchange for, or upon conversion of their interests, securities or rights and (B) in the case of securities represented by certificates, upon the surrender of such certificates, which cash, property or general or limited partner interests, rights, securities or obligations of the Surviving Business Entity or any general or limited partnership, corporation, trust, limited liability company, unincorporated business or other entity (other than the Surviving Business Entity), or evidences thereof, are to be delivered;

(v) a statement of any changes in the constituent documents or the adoption of new constituent documents (the articles or certificate of incorporation, articles of trust, declaration of trust, certificate or agreement of limited partnership, certificate of formation, limited liability company agreement or other similar charter or governing document) of the Surviving Business Entity to be effected by such merger or consolidation;

(vi) the effective time of the merger, which may be the date of the filing of the certificate of merger pursuant to Section 13.4 or a later date specified in or determinable in accordance with the Merger Agreement; provided, however, that if the effective time of the merger is to be later than the date of the filing of such certificate of merger, the effective time shall be fixed at a date or time certain at or prior to the time of the filing of such certificate of merger and stated therein; and

(vii) such other provisions with respect to the proposed merger or consolidation as are deemed necessary or appropriate by the Board.

(c) If the Board shall determine to consent to a conversion of the Company, the Board shall approve and adopt a Plan of Conversion containing such terms and conditions that the Board determines to be necessary or appropriate.

Section 13.3 Approval by Members of Merger, Consolidation or Conversion.

(a) The Board, upon its approval of the Merger Agreement or Plan of Conversion, as the case may be, shall direct that the Merger Agreement or the Plan of Conversion, as applicable, be submitted to a vote of the Members, whether at a meeting or by written consent.  A copy or a summary of the Merger Agreement or the Plan of Conversion, as applicable, shall be included in or enclosed with the notice of a special meeting or the written consent.

(b) The Merger Agreement or the Plan of Conversion, as applicable, shall be approved upon receiving the affirmative vote or consent of Members representing a Majority Interest.

(c) After such approval by vote or consent of the Members, and at any time prior to the filing of the certificate of merger, consolidation or conversion pursuant to

26

Section 13.4, the merger, consolidation or conversion may be abandoned pursuant to provisions therefor, if any, set forth in the Merger Agreement or the Plan of Conversion, as the case may be.

Section 13.4 Certificate of Merger, Consolidation or Conversion.

(a) Upon the required approval by the Board and the Members of a Merger Agreement or a Plan of Conversion, as the case may be, a certificate of merger, consolidation or conversion, as applicable, shall be executed and filed with the Secretary of State of the State of Delaware in conformity with the requirements of the Act and shall have such effect as provided under the Act or other Applicable Law.

(b) A merger, consolidation or conversion effected pursuant to this Article 13 shall not (i) to the fullest extent permitted by Applicable Law, be deemed to result in a transfer or assignment of assets or liabilities from one entity to another having occurred or (ii) require the Company (if it is not the Surviving Business Entity) to wind up its affairs, pay its liabilities or distribute its assets as required under Article 12 of this Agreement or under the applicable provisions of the Act.

Section 14.3 Entire Agreement; Superseding Effect.

This Agreement constitutes the entire agreement of the Members relating to the Company and the transactions contemplated hereby, and supersedes all provisions and concepts contained in all prior contracts or agreements between the Members with respect to the Company, whether oral or written, including the Original Limited Liability Company Agreement.

Section 14.4 Effect of Waiver or Consent.

Except as otherwise provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Member in the performance by that Member of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Member of the same or any other obligations of that Member with respect to the Company.  Except as otherwise provided in this Agreement, failure on the part of a Member to complain of any act of any Member or to declare any Member in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Member of its rights with respect to that default until the applicable statute-of-limitations period has run.

Section 14.5 Amendment or Restatement.

This Agreement may be amended or restated only by a written instrument executed by all Members; provided, however, that, notwithstanding anything to the contrary contained in this Agreement, each Member agrees that the Board, without the approval of any Member, may amend any provision of the Delaware Certificate and this Agreement, and may authorize any Officer to execute, swear to, acknowledge, deliver, file and record any such amendment and whatever documents may be required in connection therewith, to reflect any change that does not require consent or approval (or for which such consent or approval has been obtained) under this Agreement or does not materially adversely affect the rights of the Members.

Section 14.6 Binding Effect.

Subject to the restrictions on Dispositions set forth in this Agreement, this Agreement is binding on and shall inure to the benefit of the Members and their respective successors and permitted assigns.

Section 14.7 Governing Law; Severability.

THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, EXCLUDING ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE GOVERNANCE

28

OR THE CONSTRUCTION OF THIS AGREEMENT TO THE LAW OF ANOTHER JURISDICTION.  In the event of a direct conflict between the provisions of this Agreement and any mandatory, non-waivable provision of the Act, such provision of the Act shall control.  If any provision of the Act may be varied or superseded in a limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter.  If any provision of this Agreement or the application thereof to any Member or circumstance is held invalid or unenforceable to any extent, (x) the remainder of this Agreement and the application of that provision to other Members or circumstances is not affected thereby and (y) the Members shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the Members in substantially the same economic, business and legal position as they would have been in if the original provision had been valid and enforceable.

Section 14.8 Venue.

Any and all claims, suits, actions or proceedings arising out of, in connection with or relating in any way to this Agreement shall be exclusively brought in the Court of Chancery of the State of Delaware (or, to the extent the Court of Chancery lacks jurisdiction, any other state court in the State of Delaware).  Each party hereto unconditionally and irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, to the extent the Court of Chancery lacks jurisdiction, any other state court in the State of Delaware) with respect to any such claim, suit, action or proceeding and waives any objection that such party may have to the laying of venue of any claim, suit, action or proceeding in the Court of Chancery (or other state court) of the State of Delaware.

Section 14.9 Further Assurances.

In connection with this Agreement and the transactions contemplated hereby, each Member shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions.

Section 14.10 Waiver of Certain Rights.

Each Member, to the fullest extent permitted by Applicable Law, irrevocably waives any right it may have to maintain any action for dissolution of the Company or for partition of the property of the Company.

Section 14.11 Counterparts.

This Agreement may be executed in any number of counterparts with the same effect as if all signing parties had signed the same document.  All counterparts shall be construed together and constitute the same instrument.  To the fullest extent permitted by Applicable Law, the use of facsimile signatures and signatures delivered by email in portable document format (.pdf) affixed in the name and on behalf of a party is expressly permitted by this Agreement.
