         a. Purchaser Bears Economic Risk. Purchaser acknowledges that it has
such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Shares and

it own account for investment purposes only and not with a view towards further

receive and review information about the Company concerning its assets, business
operations, management, and financial condition, and other information which the
Purchaser may consider to be relevant to its decision whether to purchase the
Shares. Additionally, Purchaser represents that it has had the opportunity to
ask questions and receive answers from the Company and its management concerning
the business and financial affairs of the Company and the Purchaser desires no
additional information with respect to the Company and/or its investment in the
Shares.

Shares must be held indefinitely unless they are registered pursuant to the
Securities Act or an exemption from such registration is available. Purchaser is

satisfaction of certain conditions, including, among other things: the
availability of certain current public information about the Company, the resale
occurring not less than one year after a party had purchased and paid for the
security to be sold, the sale being through an unsolicited broker's transaction

Purchaser is bound; or (iii) any written or oral contract, agreement, or
