The initial appointees as Managers are as follows: Leroy M. Ball and Michael J. Mocniak. Each Manager shall hold office at the pleasure of the Majority-in-Interest.

If a meeting place is not so designated, the meeting shall be held at the Company’s principal office. Notwithstanding anything to the contrary in this Section 5.1, the Managers may take without a meeting any action contemplated to be taken by the Managers under this Agreement if such action is approved by the written consent of a majority of the Managers (which may be executed in counterparts).

At all meetings of the members, a Majority-in-Interest shall constitute a quorum for the transaction of business. Any action required or permitted to be taken at any meeting of the Members, or of any committee thereof, may be taken without a meeting if at least a majority of the Members or at least a majority of the members of such committee, as the case may be, consent thereto in writing (which consent may be executed in counterparts). No Member shall be prohibited from voting on a matter solely because the matter relates to such Member or an Affiliate of such Member.

(b) Committees. The Members may establish such committees, advisory councils and delegate duties to such Persons as the Members shall from time to time determine and such Persons shall serve in such capacities at the discretion of the Members.

(c) Certain Approvals by Members. Any action or transaction proposed to be effected by or on behalf of the Company that would require a vote of

stockholders under the Delaware General Corporation Law if the Company were a Delaware corporation shall require the consent of a Majority-in-Interest; provided, however, that such approval shall not be deemed to imply that any Member shall be entitled to, and no Member shall be entitled to, any form of appraisal rights of any kind under any circumstances.

Section 5.3. Delegation; Officers. The Managers shall have the power to delegate authority to such officers, employees, agents and representatives of the Company as it may from time to time deem to be appropriate.

Section 5.7. Reliance on Acts of the Managers and Others. No financial institution or other Person dealing with an officer, Manager, Member or other agent or attorney-in-fact for the Company will be required to ascertain whether any such officer, Manager, Member or other agent or attorney-in-fact is an authorized agent acting in accordance with this Agreement, but such financial institution or such other Person will be protected in relying solely upon the deed, transfer or assurances in the execution of such instrument or instruments by the officer, Manager, Member or other agent or attorney-in-fact thereof.

Section 5.8. Activity of Members. No Member or an Affiliate thereof shall engage or be interested in, as a stockholder, officer, agent, employee or otherwise, any business or undertaking which directly competes in any manner with any business in which the Company is engaged; provided, however, that the foregoing shall not prevent a Member from having a beneficial interest in any publicly traded company so long as such Member’s interest does not exceed five percent (5%) of the issued and outstanding stock of such company.

Section 5.9. Conflicts of Interest. Subject to the other express provisions of this Agreement, each Member, Manager, and officer of the Company at any time and from time to time may engage in and possess interests in other business ventures of any and every type and description, independently or with others, with no obligation to offer to the Company or any other Member, Manager or officer the right to participate therein. The Company may transact business with any Member, Manager, officer or Affiliate thereof, provided the terms of those

transactions are no less favorable than those the Company could obtain from unrelated third parties.

Section 5.10. Indemnity of the Managers, Officers, Employees, and Other Agents.

(a) The Company shall indemnify, to the fullest extent now or hereafter permitted by law, each Manager (including each former Manager) of the Company who was or is made a party to or a witness in or is threatened to be made a party to or a witness in any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was an authorized representative of the Company, against all expenses (including attorneys’ fees and disbursements), judgments, fines (including excise taxes and penalties) and amounts paid in settlement actually and reasonably incurred by such person in connection with such action or proceeding.

(b) The Company shall pay all expenses (including attorneys’ fees and disbursements) incurred by a Manager (including a former Manager) referred to in Section 5.10(a) hereof in defending or appearing as a witness in any action or proceeding described in Section 5.10(a) hereof in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of such person to repay all amounts advanced if it is ultimately determined that he or she is not entitled to be indemnified by the Company as provided in Section 5.10(d) hereof.

(c) The Company may, as determined by a Majority-in-Interest from time to time, indemnify to the fullest extent now or hereafter permitted by law, any person who was or is made a party to or a witness in or is threatened to be made a party to or a witness in, or was or is otherwise involved in, any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was an authorized representative of the Company, both as to action in such person’s official capacity and as to action in another capacity while holding such office or position, against all expenses (including attorneys’ fees and disbursements), judgments, fines (including excise taxes and penalties), and amounts paid in settlement actually and reasonably incurred by such person in connection with such action or proceeding. The Company may, as determined by a Majority-in-Interest from time to time, pay expenses incurred by any such person by reason of his or her participation in an action or proceeding referred to in this Section 5.10(c) in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Company as provided in Section 5.10(d) hereof.

(d) Indemnification under this Section shall not be made by the Company in any case where a court determines that the alleged act or failure to act giving rise to the claim for indemnification is expressly prohibited by the Act or any successor statute in effect at the time of such alleged action or failure to take action.

(e) The Company may purchase and maintain insurance on behalf of any person who is or was a Manager, or is or was an authorized representative of the Company, against any liability asserted against or incurred by such person in any such capacity, or arising

(f) Each Manager shall be deemed to act in such capacity in reliance upon such rights of indemnification and advancement of expenses as are provided in this Section. The rights of indemnification and advancement of expenses provided by this Section shall not be deemed exclusive of any other rights to which any person seeking indemnification or advancement of expenses may be entitled under any agreement, statute or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office or position, and shall continue as to a person who has ceased to be an authorized representative of the Company and shall inure to the benefit of the heirs and personal representatives of such person. Indemnification and advancement of expenses under this Article shall be provided whether or not the indemnified liability arises or arose from any threatened, pending or completed action by or in the right of the Company. Any repeal or modification of this Article shall not adversely affect any right or protection existing at the time of such repeal or modification to which any person may be entitled under this Section.

(g) For purposes of this Section, references to “the Company” shall include all constituent limited liability companies, corporations or other entities absorbed in a consolidation, merger or division, as well as the surviving or new limited liability companies, corporations or other entities surviving or resulting therefrom, so that (i) any person who is or was an authorized representative of a constituent, surviving or new limited liability company, corporation or other entity shall stand in the same position under the provisions of this Section with respect to the surviving or new limited liability company, corporation or other entity as such person would if he or she had served the surviving or new limited liability company, corporation or other entity in the same capacity and (ii) any person who is or was an authorized representative of the Company shall stand in the same position under the provisions of this Section with respect to the surviving or new corporation or other entity as such person would with respect to the Company if its separate existence had continued.

(h) For the purposes of this Section, the term “authorized representative” shall mean a Manager, officer, employee or agent of the Company or of any subsidiary of the Company, or a trustee, custodian, administrator, committeeman or fiduciary of any employee benefit plan established and maintained by the Company or by any subsidiary of the Company, or a person serving another corporation, partnership, joint venture, trust or other enterprise in any of the foregoing capacities at the request of the Company.

(i) No Member shall have any obligation to indemnify any other Member, officer, employee, agent or other authorized representative of the Company under any circumstances.

(j) No Member, Manager, officer, Company employee or Affiliate thereof or their respective agents and/or the legal representatives of any of them shall be liable to any Member, the Company or any other Person for mistakes of judgment or for action or inaction which such Member, Manager, officer, Company employee, Affiliate, agents or legal representatives reasonably believed to be in or not opposed to the best interests of the Company unless such action or inaction constitutes willful misconduct, bad faith, gross negligence or reckless disregard of his or its duties and, with respect to any criminal action, such party

reasonably believes his conduct was lawful. Each Member and Manager may (on its own behalf or on the behalf of any Representative, any Affiliates of such Member or their respective agents and/or legal representatives of any of them), consult with counsel, accountants and other experts in respect of the Company’s affairs and such Person shall be fully protected and justified in any action or inaction which is taken in accordance with the advice or opinion of such counsel, accountants or other experts. Notwithstanding any of the foregoing to the contrary, the provisions of this Section shall not be construed so as to relieve (or attempt to relieve) any Person of any liability, to the extent (but only to the extent) that such liability may not be waived, modified or limited under applicable law, but shall be construed so as to effectuate the provisions of this Section to the fullest extent permitted by law.

Notwithstanding the foregoing, any Transfer pursuant to this Section 9.2 which, alone or together with previous transfers, causes a termination of the Company pursuant to Section 708 of the IRC shall require the prior written consent of the Members.

Section 9.3. Transferee Not Member in Absence of Unanimous Consent. Notwithstanding anything contained in this Agreement to the contrary, if all of the remaining Members do not approve by written consent (which consent may be withheld at their sole and absolute discretion) of the proposed Transfer of an Interest, the proposed transferee shall have no right to participate in the management of the business and affairs of the Company or to become a Member. Rather, such transferee shall become only an assignee of a Member with rights only to distributions and no voting rights, and shall not have the rights of a substituted Member.

Section 9.4. Withdrawal. Each Member shall have the right to withdraw from the Company at any time upon written notice to the Company; such Member’s withdrawal shall be effective on the date specified in the withdrawing Member’s notice or upon such earlier date as the Members may determine. Such withdrawn Member shall receive from the Company at the effective date of such withdrawn Member’s withdrawal cash in an amount equal to its Capital Account. From and after the effective date of such withdrawal, such withdrawn Member shall have no further right or interest in the Company or any of its assets or records or affairs and such withdrawn Member shall no longer be a Member in the Company.
