    Corporation shall transfer the Facilities to F&J, LLC; and (ii) F&J, LLC
    shall assume all loans secured by the Facilities (including any loans made
    or guaranteed by the SBA), in each case in a manner pre-approved by Bristol
    in its absolute and sole discretion. Shareholder acknowledges that Surviving
    Corporation is retaining title to the Facilities for a period of one (1) day
    following the Closing Date to simplify negotiations and to accommodate
    Shareholder, and Shareholder expressly agrees that he will indemnify, defend
    and hold harmless Bristol, Purchaser and Surviving Corporation from and

    any other right or remedy available to Bristol, Purchaser or Surviving
    Corporation under this indemnity, under the other provisions of this
    Agreement, at law, in equity or otherwise, Bristol, Purchaser and/or
    Surviving Corporation shall have the right to offset such Liability against
    (i) any fees or commissions otherwise due Shareholder under that certain
    Independent Contractor Agreement described in Section 6.2, below; or (ii)
