UPDATES TO PROSPECTUS

The following replaces the paragraph under "New Jersey" in the "Suitability Standards" section of the Prospectus:

New Jersey - New Jersey investors must have either (a) a minimum liquid net worth of at least $100,000 and a minimum annual gross income of not less than $100,000, or (b) a minimum liquid net worth of $350,000. For these purposes, "liquid net worth" is defined as that portion of net worth (total assets exclusive of home, home furnishings, and automobiles, minus total liability) that consists of cash, cash equivalent and readily marketable securities. In addition, a New Jersey investor's investment in us, our affiliates, and other non-publicly traded direct investment programs (including real estate investment trusts, business development companies, oil and gas programs, equipment leasing programs and commodity pools (each, a "DIP Category"), but excluding unregistered, federally and state exempt private offerings) may not exceed ten percent (10%) of their liquid net worth. However, New Jersey investors who are accredited investors, as defined at N.J.S.A. 49:3-49(p), may not invest more than ten percent (10%) of their liquid net worth in each DIP Category.
