certificate theretofore issued by the Company alleged to have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When issuing
such new certificate, the Company may, in its discretion and as a condition
precedent to the issuance thereof, require the holder of such lost, stolen or
destroyed certificate, or the holder's legal representative, to advertise the

employees, affiliates, representatives or agents of the Member, or 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.

         Section 5.2. Indemnification. To the fullest extent permitted by law,
the Company shall indemnify and hold harmless each Covered Person from and
against any and all civil,


                                                                               5


criminal, administrative or investigative losses, claims, demands, liabilities,
expenses, judgments, fines, settlements and other amounts arising from any and
all claims, demands, actions, suits or proceedings, ("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 5.2
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 5.2.

         Section 5.3. Amendments. Any repeal or modification of this Article V
by the Member shall not adversely affect any rights of such Covered Person
pursuant to this Article V, including the right to indemnification and to the
advancement of 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 VI

                                  MISCELLANEOUS

the Company shall timely make any and all necessary elections and filings for
the Company treated as a disregarded entity for U.S. federal income tax purposes
(as well as for any analogous state or local tax purposes).

         Section 6.2. 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.

         Section 6.3. 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 with a valid provision
which most closely approximates the intent and economic effect of the invalid or
unenforceable provision.


                                                                               6



         Section 6.4. Governing Law. This Agreement shall be governed by and

the principles of conflicts of laws thereof.

limited liability company and does not intend to form a partnership under the
laws of the State of Delaware or any other laws.
