operation of law.

     

    2.3          Authority of
Manager.  The Manager shall have the authority to take actions
on behalf of the Company to the maximum extent permitted by the Act, subject to
any limitations or requirements expressly set forth in this

operation of the Company in accordance with this Agreement.  The Sole
Member and the Manager (if different from the Sole Member) shall be entitled to

incur any such management expenses, unless such management expenses arose from a
material violation of this Agreement, gross negligence, willful misconduct or a
knowing violation of criminal law.

     

    2.5          Compensation.  Unless

    TRANSFER
OF INTEREST

following requirements are satisfied:  (a) the proposed transaction
would apply to the entire interest of the Sole Member in the Company; (b) the
proposed transaction would involve one transferee; (c) such transferee tenders
full payment of the required purchase price; (d) such transferee executes, in

that the proposed transaction would not violate any federal or state securities
laws or any other applicable laws.  The Sole Member acknowledges and

result in more than one member and thereby cause the Company to be reclassified
for tax purposes.

     

    4.2          Effect of
Transfer.  If the Sole Member transfers the entire interest of
the Sole Member in the Company in accordance with this Agreement, such transfer
