    Mr.
      Tompkins:

    

    Reference
      is made to that certain Term Sheet (the “Term Sheet”), dated August 21, 2006,
      relating to a proposed business combination between GoFish Corporation (f/k/a
      Unibio Inc.), a Nevada corporation (the “Company”) and GoFish Technologies,
      Inc., a California corporation (“GoFish”), and a related private placement
      financing (the “Transactions”). In connection with the Transactions, the
      Company, GoFish, GF Acquisition Corp., a California corporation, ITD Acquisition
      Corp., a Delaware corporation, and Internet Television Distribution Inc., a
      Delaware corporation (“ITD”), entered into that certain Agreement and Plan of
      Merger and Reorganization (the “Merger Agreement”), dated as of October 27,
      2006, pursuant to which GoFish shareholders received common stock, par value
      $0.001 per share, of the Company (the “Common Stock”) in consideration for
      shares of GoFish held by them at the effective time of the merger. In accordance
      with the Merger Agreement, among other things, ITD Acquisition Corp. will merge
      with and into ITD, with ITD remaining as the surviving entity and a wholly-owned
      subsidiary of the Company. As a result, the Company will issue up to 3,500,000
      shares of Common Stock to the sold stockholder of ITD, Internet Television
      Distribution LLC, in which Tabreez Verjee and Riaz Valani are the only members.
      In consideration of the Company, GoFish and ITD entering into the Transactions,
      and for Tompkins Capital Group to facilitate the Transactions and for other
      good
      and valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged, the undersigned hereby agrees as follows:

    

    1. The
      undersigned hereby covenants and agrees, except as provided herein, not to
      (1)
      offer, sell, contract to sell or otherwise dispose of and (2) transfer title

      acquired by the undersigned pursuant to or in connection with the Merger
      Agreement (including as a result of shares owned as a GoFish shareholder and
      shares owned beneficially as a member of Internet Television Distribution LLC),
      during the period commencing on the “Closing Date” (as that term is defined in
      the Term Sheet) and ending on the 24-month anniversary of the Closing Date
      (the

      Capital Group (which consent shall not be unreasonably withheld).
      Notwithstanding the foregoing, the undersigned shall be permitted from time
      to
      time during the Lockup Period, without the prior written consent of the Company
      or Tompkins Capital Group, as applicable, (i) to acquire shares of Common Stock
      pursuant to the undersigned’s participation in the Company’s stock option plan,
      or (ii) to transfer all or any part of the Acquired Shares to any family member,
      for estate planning purposes or to an affiliate thereof (as such term is defined
      in Rule 405 under the Securities Exchange Act of 1933, as amended), provided
      that such transferee agrees with the Company and Tompkins Capital Group to
      be
      bound hereby, and in any transaction in which holders of the Common Stock of
      the
      Company participate or have the opportunity to participate pro rata, including,
      without limitation, a merger, consolidation or binding share exchange involving
      the Company, a disposition of the Common Stock in connection with the exercise
      of any rights, warrants or other securities distributed to the Company’s
      stockholders, or a tender or exchange offer for the Common Stock, and no
      transaction contemplated by the foregoing clauses (i) or (ii) shall be deemed
      a
      Prohibited Sale for purposes of this Letter Agreement.

      Letter Agreement shall be governed by and construed in accordance with the
      laws
