Delaware that, in either case, are incidental to and necessary, suitable or
convenient for the accomplishment of the above-mentioned purposes.

the Company.

     Section 2.08. NO STATE LAW PARTNERSHIP. No provisions of this Agreement
(including, without limitation, the provisions of Article 6) shall be deemed or
construed to constitute a partnership (including, without limitation, a limited
partnership) or joint venture, or the Sole Member a partner or joint venturer of
or with any Director or the Company, for any purposes.

     Section 2.09. ADDRESS OF THE SOLE MEMBER. The address of the Sole Member is
set forth on EXHIBIT A, as amended from time to time, attached hereto and made a

                                  ARTICLE III.

                                      TERM

     Section 3.01. COMMENCEMENT. The Company's term commenced upon the filing of
the Certificate with the Secretary on January 29, 1999. The existence of the
Company as a separate legal entity shall continue until the cancellation of the
Certificate as provided in the Act.

     Section 3.02. CONTINUATION. Notwithstanding any provision of this
Agreement, a Bankruptcy of the Sole Member will not cause the Sole Member to
cease to be a member of the Company, and upon the occurrence of such an event,
the business of the Company shall continue without dissolution. Notwithstanding
any other provision of this Agreement, the Sole Member waives any right it might
have under Section 18-801(b) of the Act to agree in writing to dissolve the
Company upon the occurrence of a Bankruptcy of the Sole Member or the occurrence
of any other event which under the Act would otherwise cause the Sole Member to
cease to be a member of the Company.


                                   ARTICLE IV.

                              CAPITAL CONTRIBUTIONS

     Section 4.01. CAPITAL CONTRIBUTION. The Sole Member may be required or
shall be permitted to make Capital Contributions in cash or property to the
Company on such terms and conditions as may be agreed to by the Sole Member from
time to time. The amounts so contributed by the Sole Member shall be credited to
the Sole Member's capital account, as provided in Section 4.02 below. The Sole
Member shall have a Membership Interest of one hundred percent (100%) of the
Company.

     Section 4.02. CAPITAL ACCOUNT. The Company shall establish an individual
Capital Account for the Sole Member (the "Capital Account").

     Section 4.03. INTEREST ON AND RETURN OF CAPITAL ACCOUNT. The Sole Member
shall be entitled to interest on its Capital Contribution to the extent
permitted in the Indenture and the Basic Documents.

                                   ARTICLE V.

                               ALLOCATIONS; BOOKS

     Section 5.01. ALLOCATIONS OF INCOME AND LOSS.

     (a) BOOK ALLOCATIONS. The net income and net loss of the Company shall be
allocated entirely to the Capital Account of the Sole Member.


                                      -14-


   15


     (b) TAX ALLOCATIONS. Because the Company is not making (and will not make)
an election to be treated as an association taxable as a corporation under
Section 301.7701-3(a) of the U.S. Treasury Regulations, and because the Company
is a business entity that has a single owner and is not a corporation, it shall
be disregarded as an entity separate from its owner for federal income tax
purposes under Section 301.7701-3(b)(1) of the U.S. Treasury Regulations.
Accordingly, all items of income, gain, loss, deduction and credit of the
Company for all taxable periods will be treated for federal income tax purposes,
and for state and local income and other tax purposes to the extent permitted by
applicable law, as realized or incurred directly by the Sole Member. To the
extent not so permitted, all items of income, gain, loss, deduction and credit
of the Company shall be allocated entirely to the Sole Member.

     Section 5.02. BOOKS OF ACCOUNT. At all times during the continuance of the
Company, the Company shall maintain or cause to be maintained full, true,
complete and correct books of account in accordance with GAAP, using the fiscal
year and taxable year of the Sole Member. In addition, the Company shall keep
all records required to be kept pursuant to the Act.

     Section 5.03. DISTRIBUTIONS. The Company may make distributions to the Sole
Member from time to time upon the unanimous vote of the Management Committee.
Notwithstanding any provision to the contrary contained in this Agreement, the
Company shall not be required to make a distribution to the Sole Member on
account of its interest in the Company if such distribution would violate
Section 18-607 of the Act or any other applicable law or any of the Basic
Documents.

                                   ARTICLE VI.

                            MANAGEMENT OF THE COMPANY

     Section 6.01. MANAGEMENT OF COMPANY. Except as otherwise provided in this
Agreement, the property and business of the Company shall be controlled and
managed by the Management Committee provided, however, that except as otherwise
provided in this Agreement, the Officers acting alone can bind or execute any
instrument on behalf of the Company, and may sign all checks, drafts, and other
instruments obligating the Company to pay money. Notwithstanding the last
sentence of Section 18-402 of the Act, except as provided in this Agreement, a
Director may not bind the Company. Prior to the entry into any Sale Agreement
and the acquisition of any Transition Property, the Sole Member shall appoint
two Independent Directors. In the event that an Independent Director withdraws,
resigns or is removed as Independent Director, the Sole Member shall appoint, as
soon as reasonably practicable, a successor Independent Director. The Company
shall pay each Independent Director an annual fee totaling not less than
$1,000 per year. Each Director, including each Independent Director, is hereby
deemed to be a "manager" within the meaning of Section 18-101(10) of the Act.


                                      -15-


   16


     Section 6.02. WITHDRAWAL OF DIRECTOR. Notwithstanding anything herein to
the contrary, an Independent Director may not withdraw or resign as a Director
of the Company without the consent of the Sole Member.

     Section 6.03. DUTIES OF DIRECTORS. To the fullest extent permitted by
applicable law, including without limitation Section 18-1101(c) of the Act, the
fiduciary duty of the Directors, including the Independent Directors, in respect
of any decision on any matter referred to in this Agreement shall be owed solely
to the Company (including its creditors) and not to the Sole Member or any other
holder of an equity interest in the Company as may exist at such time. Each
Director shall execute and deliver the Management Agreement.

     Section 6.04. REMOVAL OF DIRECTOR. A Director (including the Independent
Director) may be removed at any time, with or without cause, upon the written
election of the Sole Member.

     Section 6.05. QUORUM: ACTS OF THE MANAGEMENT COMMITTEE. At all meetings of
the Management Committee, a majority of the Directors shall constitute a quorum
for the transaction of business and, except as otherwise provided in any other
provision of this Agreement, the act of a majority of the Directors present at
any meeting at which there is a quorum shall be the act of the Management
Committee. If a quorum shall not be present at any meeting of the Management
Committee, the Directors present at such meeting may adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a
quorum shall be present. The Directors may participate in meetings of the
Management Committee by means of telephone conference or similar communications
equipment that allows all persons participating in the meeting to hear each
other, and such participation in a meeting shall constitute presence in person
at the meeting. If all the participants are participating by telephone
conference or similar communications equipment, the meeting shall be deemed to
be held at the principal place of business of the Company. Any action required
or permitted to be taken at any meeting of the Management Committee or any
committee thereof 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 Directors having not less than the minimum number
of votes that would be necessary to authorize or take such action at a meeting.
Unless otherwise provided in the Agreement, on any matter that is to be voted on
by Directors, the Directors may vote in person or by proxy.

     Section 6.06. OFFICERS. The Sole Member may, from time to time as it deems
advisable, appoint officers of the Company (the "Officers") and assign in
writing titles (including, without limitation, President, Vice President,
Secretary, and Treasurer) to any such person. Unless the Sole Member decides
otherwise, if the title is one commonly used for officers of a business
corporation formed under the Delaware General Corporation Law the assignment of
such title shall constitute the delegation to such person of the authorities and
duties that are normally associated with that office. Any delegation pursuant to
this Section 6.06 may be revoked at any time by the Sole Member. The Officers
shall be those individuals listed on Schedule 6.06 from


                                      -16-


   17


time to time attached hereto. The Sole Member may revise Schedule 6.06 in its
sole discretion at any time.

                                  ARTICLE VII.

                     DISSOLUTION, LIQUIDATION AND WINDING-UP

     Section 7.01. DISSOLUTION. The Company shall be dissolved and its affairs
shall be wound up upon the occurrence of the earliest of the following events:

     (a) subject to Section 2.07, the election to dissolve the Company made in
writing by the Sole Member and each Director, including without limitation each
Independent Director, as permitted by the Basic Documents;

     (b) the occurrence of any event that causes the Sole Member of the Company
to cease to be a member of the Company unless the business of the Company is
continued without dissolution in a manner permitted by the Act; or

     (c) the entry of a decree of judicial dissolution of the Company pursuant
to Section 18-802 of the Act.

     Section 7.02. ACCOUNTING. In the event of the dissolution, liquidation and
winding-up of the Company, a proper accounting shall be made of the Capital
Account of the Sole Member and of the net income or net loss of the Company from
the date of the last previous accounting to the date of dissolution.

     Section 7.03. CERTIFICATE OF CANCELLATION. As soon as possible following
the occurrence of any of the events specified in Section 7.01 and the completion
of the winding up of the Company, the person or entity winding up the business
and affairs of the Company shall cause to be executed a Certificate of
Cancellation of the Certificate in such form as shall be prescribed by the
Secretary and file the Certificate of Cancellation of the Certificate as
required by the Act.

     Section 7.04. WINDING UP. Upon the occurrence of any event specified in
Section 7.01, the Company shall continue solely for the purpose of winding up
its affairs in an orderly manner, liquidating its assets, and satisfying the
claims of its creditors. The Sole Member shall be responsible for overseeing the
winding up and liquidation of the Company, shall take full account of the
liabilities of the Company and its assets, shall either cause its assets to be
sold or distributed, and if sold as promptly as is consistent with obtaining the
fair market value thereof, shall cause the proceeds therefrom, to the extent
sufficient therefor, to be applied and distributed as provided in Section 7.06.

     Section 7.05. ORDER OF PAYMENT OF LIABILITIES UPON DISSOLUTION. After
determining that all known debts and liabilities of the Company, including all
contingent, conditional or unmatured liabilities of the Company, in the process
of winding-up, including, without


                                      -17-


   18


limitation, debts and liabilities to the Sole Member in the event it is a
creditor of the Company to the extent otherwise permitted by law, have been paid
or adequately provided for, the remaining assets shall be distributed in cash or
in kind to the Sole Member.

     Section 7.06. LIMITATIONS ON PAYMENTS MADE IN DISSOLUTION. Except as
otherwise specifically provided in this Agreement, the Sole Member shall be
entitled to look solely to the assets of the Company for the return of its
positive Capital Account balance and shall have no recourse for its Capital
Contribution and/or share of net income (upon dissolution or otherwise) against
any Director or the Management Committee.

                                  ARTICLE VIII.

                             TRANSFER AND ASSIGNMENT

     Section 8.01. TRANSFER OF MEMBERSHIP INTERESTS.

     (a) The Sole Member may transfer its Membership Interest, but the
transferee shall not be admitted as a member except in accordance with Section
8.02. Until the transferee is admitted as a member, the Sole Member shall
continue to be the sole member of the Company and to be entitled to exercise any
rights or powers of the Sole Member with respect to the Membership Interest
transferred.

     (b) Any purported transfer of any Membership Interest in violation of the
provisions of this Agreement shall be wholly void and shall not effectuate the
transfer contemplated thereby. Notwithstanding anything contained herein to the
contrary, the Sole Member may not transfer any Membership Interest in violation
of any provision of this Agreement or in violation of any applicable Federal or
state securities laws.

     Section 8.02. ADMISSION OF TRANSFEREE AS MEMBER. A transferee of a
Membership Interest desiring to be admitted as a member must execute a
counterpart of, or an agreement adopting, this Agreement and shall not be
admitted without the unanimous affirmative vote of the Management Committee,
which vote must include the affirmative vote of the Independent Directors. Upon
admission of the transferee as a member, the transferee shall have, to the
extent of the Membership Interest transferred, the rights and powers and shall
be subject to the restrictions and liabilities of the Sole Member under this
Agreement and the Act. Notwithstanding anything in this Agreement to the
contrary, any successor to the Sole Member by merger or consolidation in
compliance with the Basic Documents shall, without further act, be the Sole
Member hereunder, and such merger or consolidation shall not constitute a
transfer for purposes of this Agreement.

                                   ARTICLE IX.

     Section 9.01. NOTICES. All notices or other communications required or

shall bear the signatures of all of the parties reflected hereon as the
signatories.

     Section 9.04. SEVERABILITY. The provisions of this Agreement are

     Section 9.05. ENTIRE AGREEMENT. This Agreement contains the entire
understanding among the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and

solely of the Company, and neither the Sole Member nor any Director or Officer

the Company. To the extent permitted by applicable law, no Director or Officer

                                   ARTICLE X.

                                 INDEMNIFICATION

     Section 10.01. INDEMNIFICATION. Subject to Section 10.03 of this Article,
the Company shall, to the fullest extent permitted by law, 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
Company) by reason of the fact that he is or was a director, manager, officer,
employee or agent of the Company, or is or was serving at the request of the
Company as a manager, director, officer, employee or agent of another 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,
proceeding or in enforcing such person's right to indemnification hereunder, 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 Company, 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 Company, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.


     Section 10.02. INDEMNIFICATION FOR SUITS BY OR IN RIGHT OF COMPANY. Subject
to Section 10.03 of this Article, the Company shall, to the fullest extent
permitted by law, 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 Company to procure a judgment in its favor by reason of the
fact that he is or was a director, manager, officer, employee or agent of the
Company, or is or was serving at the request of the Company as a manager,
director, officer, employee or agent of another 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 or enforcing such person's right to
indemnification hereunder, 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
Company; 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 Company 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 as the Court of Chancery or such other court shall deem proper.


                                      -21-


   22


     Section 10.03. AUTHORIZATION. Any indemnification under this Article
(unless ordered by a court) shall be made by the Company only as authorized in
the specific case upon a determination that indemnification of the manager,
officer, employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 10.01 or Section 10.02, of
this Article, as the case may be. Such determination shall be made (i) by
independent legal counsel in a written opinion or (ii) by the Sole Member. To
the extent, however, that a manager, officer, employee or agent of the Company
has been successful on the merits or otherwise in defense of any action, suit or
proceeding described above, 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, without the necessity of
authorization in the specific case.

     Section 10.04. GOOD FAITH. For purposes of any determination under Sections
10.03 or 9.09 of this Agreement, a person shall be deemed to have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company, or, with respect to any criminal action or proceeding,
to have had no reasonable cause to believe his conduct was unlawful, if his
action is based on the records or books of account of the Company or another
enterprise, or on information supplied to him by the officers of the Company or
another enterprise in the course of their duties, or on the advice of legal
counsel for the Company or another enterprise or on information or records given
or reports made to the Company or another enterprise by an independent certified
public accountant or by an appraiser or other expert selected with reasonable
care by the Company or another enterprise. The term "another enterprise" as used
in this Section 10.04 shall mean any corporation, partnership, limited liability
company, joint venture, trust or other enterprise of which such person is or was
serving at the request of the Company as a manager, director, officer, employee
or agent. The provisions of this Section 10.04 shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth in Sections
10.01 or 10.02 of this Article, as the case may be.

     Section 10.05. COURT ACTION. Notwithstanding any contrary determination in
the specific case under Section 10.03 of this Article, and notwithstanding the
absence of any determination thereunder, any manager, officer, employee or agent
may apply to any court of competent jurisdiction in the State of Delaware for
indemnification to the extent otherwise permissible under Sections 10.01 and
10.02 of this Article. The basis of such indemnification by a court shall be a
determination by such court that indemnification of the manager, officer,
employee or agent is proper in the circumstances because he has met the
applicable standards of conduct set forth in Section 10.01 and 10.02 of this
Article, as the case may be. Notice of any application for indemnification
pursuant to this Section 10.05 shall be given to the Company promptly upon the
filing of such application.

     Section 10.06. EXPENSES. Expenses incurred in defending or investigating a
threatened or pending action, suit or proceeding may be paid by the Company in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of


                                      -22-


   23



the manager, officer, employee or agent to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Company as authorized in this Article.

     Section 10.07. NON-EXCLUSIVITY. The indemnification and advancement of
expenses provided by or granted pursuant to this Article 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, contract,
vote or pursuant to the direction (howsoever embodied) of any court of competent
jurisdiction or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, it being the policy of the
Company that indemnification of the persons specified in Sections 10.01 and
10.02 of this Article shall be made to the fullest extent permitted by law. The
provisions of this Article shall not be deemed to preclude the indemnification
of any person who is not specified in Section 10.01 or 10.02 of this Article but
who the Company has the power or obligation to indemnify under the provisions of
the Act, or otherwise.

     Section 10.08. INSURANCE. The Company may purchase and maintain insurance
on behalf of any person who is or was a manager, officer, employee or agent of
the Company, or is or was serving at the request of the Company as a manager,
director, officer, employee or agent of another company, partnership, joint
venture, trust or other enterprise against any liability asserted against
him/her and incurred by him/her in any such capacity, or arising out of his/her
status as such, whether or not the Company would have the power or the
obligation to indemnify him against such liability under the provisions of this
Article.

     Section 10.09. CONSOLIDATION/MERGER. For purposes of this Article,
references to "the Company" shall include, in addition to the Company, any
constituent company (including any constituent of a constituent) absorbed in a
consolidation or merger that, if its separate existence had continued, would
have had the power and authority to indemnify its managers, directors, officers,
and employees or agents, so that any person who is or was a manager, director,
officer, employee or agent of such constituent company, or is or was serving at
the request of such constituent company as a manager, director, officer,
employee or agent of another company, partnership, joint venture, trust or other
enterprise, shall stand in the same position under the provisions of this
Article with respect to the resulting or surviving company as he would have with
respect to such constituent company if its separate existence had continued.
