    (a) forestalling any potential lawsuits from current shareholders of the
    Constituent Corporations and thus supporting the financial viability of UCB
    on an ongoing basis, (b) inducing the investment by the Purchaser
    contemplated by this Agreement, thus protecting Bernau's investment in the

    of Section 10.4) and in such denominations as the Purchaser requests, (ii)
    Bernau shall deliver to UCB certificates representing the Cancellation
    Shares to be transferred to UCB registered in UCB's name and UCB shall take

    and (iii) UCB shall deliver to the Purchaser certificates representing the
    Purchase Shares, registered in the Purchaser's name (subject to the

    consisting of (a) a certified or bank check in the name of UCB in the
    amount of $2,750,000 plus an amount equal to the difference between the
    full amount of the $2,750,000 Bridge Loans and the actual amount loaned by
    UBA under the Bridge Loans and (b) if all of the outstanding principal
    amount due under the Bridge Loans has been repaid, a certified or bank
    check in the name of UCB in the amount of $2,750,000, otherwise, by
    contributing to UCB the aggregate principal amount due under the Bridge
    Loans as of the Closing Date."
