(b) The definition of “Restricted Investment” is hereby deleted in its entirety and replaced with the following:

“ “Restricted Investment” means any loan, advance, capital contribution or transfer (including by way of guaranty or other similar arrangement) in or to any Unrestricted Subsidiary, Homebuilding Joint Venture or any Person in which the Company, directly or indirectly, has an ownership interest but less than an 80% ownership interest; provided, however, that loans, advances, capital contributions or transfers (including by way of guaranty or other similar arrangement) to a Homebuilding Joint Venture shall be counted as a Restricted Investment only to the extent that the aggregate at any one time outstanding of all such amounts expended (or with respect to guaranties or similar arrangements the amounts then guaranteed) exceeds, subsequent to December 31, 1996, $30 million for any one Homebuilding Joint Venture or 25% of Consolidated Tangible Net Worth in the aggregate for all Homebuilding Joint Ventures. In the case of any loan to value maintenance agreement (or similar agreement) by which the Company or any Restricted Subsidiary agrees to maintain for a joint venture a minimum ratio of indebtedness outstanding to value of collateral property, only amounts owing by the Company or the Restricted Subsidiary (or which would be owing upon demand of the lender) under such agreements will be counted as a Restricted Investment. Restricted Investment shall include the fair market value of the net assets of any Restricted Subsidiary that at any time is designated an Unrestricted Subsidiary. Any property transferred to an Unrestricted Subsidiary, and the net assets of a Restricted Subsidiary that is designated an Unrestricted Subsidiary, shall be valued at fair market value at the time of such transfer, in each case as determined by the Board of Directors of the Company in good faith.”
