      1.1 FORMATION. On December 10, 2003, the Company was formed by filing a
duly executed Certificate of Formation with the Delaware Secretary of State in
accordance with and pursuant to the provisions of the Act (as hereinafter
defined). If there is 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 provides that it may be varied or
superseded in the limited liability company agreement (or otherwise by agreement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be deemed superseded and waived in its entirety if this Agreement contains a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 provisions of this
Agreement would cause the Company not to be taxed as a partnership for federal
income tax purposes under the provisions of the Code, such provisions of the
Agreement shall be void to the extent necessary to ensure the Company is taxed
as a partnership for federal income tax purposes. If there is a conflict between
this Agreement and the Certificate of Formation, the provisions of the
Certificate of Formation shall control.

      8.1 GENERAL POWERS. Management of the Company's business and affairs shall
be exclusively vested in a Board of one or more managers (the "Board of
Managers") elected by the affirmative vote or written consent of Members holding
a majority of the Units. The Members, by virtue of having the status as Members,
shall have no management power over the business and affairs of the Company or
actual or apparent authority to enter into contracts on behalf of, or to
otherwise bind, the Company, provided, however that the Members shall have the
right to execute certain required filings with governmental authorities on
behalf of the Company, including filings to qualify to do business and filings
with the United States Internal Revenue Service. The Board of Managers shall
elect and remove such officers (the "Officers") and hire such employees as it
deems appropriate. The Officers shall have the titles, terms, power, authority,
and duties as determined by the Board of Managers. The Board of Managers and the
Officers (to the extent determined by the Board of Managers) shall have full
power and authority to do all things on such terms as they, in their individual
sole discretion, may deem necessary or appropriate to conduct, or to cause to be
conducted, the business and affairs of the Company.

                                        3


Without limiting the generality of the foregoing, the Board of Managers shall
have the right, power and authority on behalf of the Company:

            (i) to develop, review and approve annual budgets, policies,
      operating guidelines, and other key operational items for the Company;

            (ii) to arrange for such personnel as may be necessary or convenient
to carry out the business and affairs of the Company;

            (iii) to establish such reasonable cash reserves to provide for
anticipated expenses of the Company as the Board of Managers determines to be
necessary for timely payment of such expenses; and

            (iv) to direct the appropriate Officers of the Company to make,
execute, assign, acknowledge and file on behalf of the Company any and all
documents or instruments of any kind which the Board of Managers may deem
necessary or appropriate in carrying out the business and affairs of the
Company, including without limitation, powers of attorney, agreements of
indemnification, documents or instruments of any kind or character, and
amendments thereto (and no person, firm or corporation dealing with the Board of
Managers shall be required to determine or inquire into the authority or power
of the Board of Managers to bind the Company or to execute, acknowledge or
deliver any and all documents in connection therewith).

      8.2 BOARD OF MANAGERS. The managers serving on the Board of Managers
(each, a "Manager" and collectively, the "Managers") need not be Members of the
Company. The initial Manager shall be Michael J. Quillen. Except as otherwise
provided herein, all decisions to be made or actions to be taken by the Company
with respect to the Company's business shall be made by a majority vote of the
Managers serving on the Board of Managers at which a quorum is present. Each
Manager shall have one vote. Successor or additional Managers shall be elected
by the Members. Any Manager may be removed as a Manager, with or without cause,
by the Members.

      8.3 MEETINGS OF BOARD OF MANAGERS; ACTION IN LIEU OF MEETINGS. If at any
time there is more than one Manager, (a) meetings of the Board of Managers may
be held upon the written or telephonic request of any Manager, (b) attendance at
a meeting of a majority of the Board of Managers shall constitute a quorum for
the purpose of transacting business at that meeting, (c) the act of a majority
of the Managers present at a meeting of the Board of Managers at which a quorum
is present shall be deemed to constitute the act of the Board of Managers and
(d) the Board of Managers may conduct meetings by means of a conference
telephone or similar equipment, and may take action by written consent of a
majority of the Managers without a meeting if a majority of the Managers consent
in writing.

      8.4 DUTIES OF THE MANAGERS; FIDUCIARY RELATIONSHIP. Each Manager shall
perform his duties in good faith, in a manner he reasonably believes to be in
the best interests of the

                                        4


Company, and with such care as an ordinarily prudent person in a like position
would use under similar circumstances. Except as provided in Section 9.2, no
Manager shall have any liability to the Company or its Members or assignees for
monetary damages for breach of fiduciary duty.

      8.5 POWERS OF THE BOARD OF MANAGERS; RELIANCE ON EXPERTS.

        (a) Except as otherwise provided in this Agreement, the Board of
  Managers shall have all the powers conferred upon Managers by the Act and this
  Agreement, including but not limited to, (i) the right to choose and hire
  employees; and (ii) the right to select the provider of any insurance to or
  for the benefit of the Company, and purchase, modify or terminate any such
  insurance. The Board of Managers shall have no authority to do any act in
  contravention of either the Certificate of Formation or this Agreement.

        (b) In performing its duties, the Board of Managers shall be entitled to
  rely on information, opinions, reports or statements of one or more agents of
  the Company whom the Managers reasonably believe to be reliable and competent
  in the matters presented or any attorney, public accountant or other person as
  to matters which the Managers reasonably believe to be within such person's
  professional or expert competence.

      8.6 RESIGNATIONS. Any Manager may resign at any time upon notice given in
writing or by electronic transmission. The resignation shall take effect at the
time specified therein, and if no time is specified, at the time of its receipt
by the President or Secretary of the Company. The acceptance of a resignation
shall not be necessary to make it effective.

                                   ARTICLE IX

                    INDEMNIFICATION OF OFFICERS AND MANAGERS

      9.1 INDEMNIFICATION. To the fullest extent permitted by the Act, the
Company shall indemnify its Managers, Officers, employees and agents, or persons
serving at the request of the Company as a manager, director, officer, employee
or agent of another entity, 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 or administrative (each, an "Indemnitee"), against and
from any personal loss, liability or damage incurred as a result of any act or
omission that such Indemnitee believes in good faith to be within the scope of
authority conferred by this Agreement, except for willful misconduct or gross
negligence.

      9.2 EXCULPATION OF LIABILITY OF MANAGERS OR OFFICERS. No Manager or
Officer shall be liable for errors in judgment or for any act or omission if
such person acts in good faith. Notwithstanding anything to the contrary set
forth in this Agreement, no Manager or Officer shall be liable to the Company or
to the Members for monetary damages or losses sustained or liabilities incurred
as a result of any act or omission constituting a breach of such Manager's or
Officer's fiduciary duty, except: (i) for a breach of such person's duty of
loyalty to the Company or the Members; (ii) for acts or omissions not in good
faith or which involve intentional

                                        5


misconduct or a knowing violation of law; or (iii) for any transaction from
which such person derived an improper personal benefit. If the D.G.C.L. is
amended after the date of this Agreement to authorize Delaware corporations to
further eliminate or limit the personal liability of directors of Delaware
corporations, then the liability of a Manager and an Officer to the Company, in
addition to the personal limitations provided herein, shall be further limited
to the fullest extent permitted of Delaware corporations under the D.G.C.L. as
so amended.

the Units.
