good faith on behalf of the Company. Whenever in this Agreement a Covered Person
is permitted or required to make decisions in good faith, the Covered Person
shall act under such standard and shall not be subject to any other or different
standard imposed by this Agreement or any relevant provisions of law or in
equity or otherwise.

            (b) A Covered Person shall be fully protected in relying in good

      18. Fiduciary Duty. To the extent that, at law or in equity, a Covered
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Company or to the Member, a Covered Person acting under this Agreement
shall not be liable to the Company or to the Member for such Covered Person's
good faith reliance on the provisions of this Agreement. The provisions of this
Agreement, to the extent that they restrict the duties and liabilities of a
Covered Person otherwise existing at law or in equity, are agreed by the Member
to replace such other duties and liabilities of such Covered Person.

      19. Indemnification. To the fullest extent permitted by applicable law, a
Covered Person shall be entitled to indemnification from the Company for any
loss, liability, damage or claim incurred by such Covered Person by reason of
any act or omission performed or omitted by such Covered Person in good faith on
behalf of the Company; provided, that any indemnity under this Section 19 shall
be provided out of and to the extent of the Company's assets only, and no
Covered Person shall have any personal liability on account thereof.

benefit of the Member and the Company and inure to the benefit of the Covered
Persons and, in each case, their respective successors and permitted assigns.

      21. Severability. The invalidity or unenforceability of any particular
provision of this Agreement shall not affect the other provisions hereof, and
this Agreement shall be construed in all respects as if such invalid or
unenforceable provision was omitted.

Member with respect to the subject matter hereof and supersedes all prior
agreements and understandings pertaining thereto.
