     3.  Pledgee’s Duties . To the extent permitted under the Uniform Commercial Code as in effect in the State of Michigan from time to time (the “Code”) and the provisions of this Agreement, Pledgee shall have no duty with respect to the Membership Interest Collateral. Without limiting the generality of the foregoing, Pledgee shall be under no obligation to take any steps necessary to preserve rights in the Membership Interest Collateral against any other parties or to exercise any rights represented thereby; provided , however , that Pledgee may, at his option, do so, and any and all expenses incurred in connection therewith shall be for Pledgor’s sole account.

     4.  Distributions . So long as no Event of Default (as defined in the Loan Agreements) has occurred and is continuing, Pledgor shall be entitled to receive for its own use all dividends and distributions with respect to the Membership Interest Collateral. If an Event of Default has occurred and is continuing, Pledgor shall not be entitled to receive or retain any dividends or distributions paid in respect of the Membership Interest Collateral, and any and all such dividends or distributions shall be forthwith delivered to the Pledgee to hold as collateral and shall, if received by Pledgor, be received in trust for delivery to the Pledgee, and be segregated from the other property or accounts of Pledgor until delivered to the Pledgee.

     5.  Representations, Warranties and Covenants . Pledgor represents, warrants and covenants that:
