                         Exculpation and Indemnification

     8.1 Exculpation. Notwithstanding any other provisions of this Agreement,
whether express or implied, or any obligation or duty at law or in equity, none
of the Member, or any officers, directors, stockholders, partners, employees,
affiliates, representatives or agents of any of the Member, nor any officer,
employee, representative or agent of the Company (individually, a "Covered
Person" and, collectively, the "Covered Persons") shall be liable to the Company
or any other person for any act or omission (in relation to the Company, its
property or the conduct of its business or affairs, this Agreement, any related
document or any transaction or investment contemplated hereby or thereby) taken
or omitted by a Covered Person in the reasonable belief that such act or
omission is in or is not contrary to the best interests of the Company and is
within the scope of authority granted to such Covered Person by the Agreement,
provided such act or omission does not constitute fraud, willful misconduct, bad
faith, or gross negligence.




     8.2 Indemnification. To the fullest extent permitted by law, the Company
shall indemnify and hold harmless each Covered Person from and against any and
all losses, claims, demands, liabilities, expenses, judgments, fines,
settlements and other amounts arising from any and all claims, demands, actions,
suits or proceedings, civil, criminal, administrative or investigative
("Claims"), in which the Covered Person may be involved, or threatened to be
involved, as a party or otherwise, by reason of its management of the affairs of
the Company or which relates to or arises out of the Company or its property,
business or affairs. A Covered Person shall not be entitled to indemnification
under this Section 8.2 with respect to (i) any Claim with respect to which such
Covered Person has engaged in fraud, willful misconduct, bad faith or gross
negligence or (ii) any Claim initiated by such Covered Person unless such Claim
(or part thereof) (A) was brought to enforce such Covered Person's rights to
indemnification hereunder or (B) was authorized or consented to by the Member.
Expenses incurred by a Covered Person in defending any Claim shall be paid by
the Company in advance of the final disposition of such Claim upon receipt by
the Company of an undertaking by or on behalf of such Covered Person to repay
such amount if it shall be ultimately determined that such Covered Person is not
entitled to be indemnified by the Company as authorized by this Section 8.2.

     8.3 Amendments. Any repeal or modification of this Article VIII by the
Member shall not adversely affect any rights of such Covered Person pursuant to
this Article VIII, including the right to indemnification and to the advancement
of


                                        5

<PAGE>

expenses of a Covered Person existing at the time of such repeal or modification
with respect to any acts or omissions occurring prior to such repeal or
modification.


                                    ARTICLE 9
                                  Miscellaneous

     9.1 Tax Treatment. (a) It is the intention of the Member that, for U.S.
federal, state and local income and franchise tax purposes, the Company shall be
disregarded as an entity separate from the Member, as long as the Member is the
holder of all the beneficial interest in the Company for U.S. federal income tax
purposes. Accordingly, during such period, (i) except to the extent required by
appropriate tax authorities, the Member will file or cause to be filed any
annual or other necessary returns, reports and other forms consistent with the
characterization of the Company as a division or branch of the Member for such
tax purposes, and (ii) all net income of the Company for any month as determined
solely for federal income tax purposes (and each item of income, gain, loss,
credit and deduction entering into the computation thereof) shall be allocated
to the Member and treated in the same manner as if the Company were a division
or branch of the Member.

     (b) In the event that two or more persons become holders of beneficial
interest in the Company for U.S. federal income tax purposes, it is intended
that (i) the Company shall be treated as a partnership for U.S. federal, state
and local income and franchise tax purposes, and such holders shall not take any
position or make any election, in a tax return or otherwise, inconsistent
therewith and (ii) this Agreement will be amended to provide for appropriate
book and tax allocations pursuant to subchapter K of the Internal Revenue Code
of 1986, as amended.

     9.2 Amendments. Amendments to this Agreement and to the Certificate of
Formation shall be approved in writing by the Member. An amendment shall become
effective as of the date specified in the approval of the Member or if none is
specified as of the date of such approval or as otherwise provided in the Act.

     9.3 Severability. If any provision of this Agreement is held to be invalid
or unenforceable for any reason, such provision shall be ineffective to the
extent of such invalidity or unenforceability; provided, however, that the
remaining provisions will continue in full force without being impaired or
invalidated in any way unless such invalid or unenforceable provision or clause
shall be so significant as to materially affect the expectations of the Member
regarding this Agreement. Otherwise, any invalid or unenforceable provision
shall be replaced by the Member


                                        6

<PAGE>

with a valid provision which most closely approximates the intent and economic
effect of the invalid or unenforceable provision.

     9.4 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without regard to the
principles of conflicts of laws thereof.

     9.5 Limited Liability Company. The Member intends to form a limited
liability company and does not intend to form a partnership under the laws of
the State of Delaware or any other laws.
