any property distributed to such Member.

      (b)  Each Member's Capital Account shall be decreased by the amount of 
cash and the gross fair market value of any Company property (other than cash)

relating to the maintenance of Capital Accounts are intended to comply with

consistent with such Regulations. In the event the Board of Members determines
that it is prudent to modify the manner in which the Capital Accounts, or any
adjustments thereto, are computed in order to comply with such Regulations, the
Board of Members may make such modification, provided that it is not likely to
have a material effect on the amounts distributed to any Member pursuant to
Section 8.2 hereof upon the dissolution of the Company. The Board of Members
also shall make any adjustments that are necessary or appropriate to maintain
equality between the Capital Accounts of the Members and the amount of Company
capital reflected on the Company's balance sheet, as computed for book purposes,
in accordance with Regulations Section 1.704-1(b)(2)(iv)(q), and make any
appropriate modifications in the event unanticipated events might otherwise
cause this Agreement not to comply with Regulations Section 1.704-1(b). Other
than as specifically required under this Article II, no Member shall have any
deficit restoration obligation or obligation to make any additional Capital
Contribution.
