ACQUISITION OR DISPOSITION OF ASSETS.

In addition, the Company assumed substantially all the liabilities of Isolation Systems as part of the Acquisition, including the payment of transaction fees associated with the Acquisition approximately in the aggregate of U.S. $1,900,000. The Asset Purchase Agreement contains customary representations and warranties from Isolation Systems and the Company and post-closing covenants including non-competition in the virtual private network area and non-solicitation and non-hiring of former Isolation Systems' employees hired by Shiva. The terms of the Acquisition were determined on the basis of arm's-length negotiations. In addition, as part of the Acquisition, Shiva and Isolation Systems entered into an agreement pursuant to which Shiva has agreed to indemnify Isolation Systems for certain potential post-closing liabilities up to an amount equal to U.S.$6,500,000. The Company, Isolation Systems and State Street Bank and Trust Company have entered into an Escrow Agreement providing, among other things, that $1,476,409 of the Purchase Price will be held in escrow to secure certain indemnification obligations of Isolation Systems to the Company under the Asset Purchase Agreement. Prior to the Acquisition, Isolation Systems developed virtual private network hardware and software solutions. The Company currently intends to continue Isolation Systems' business substantially in the manner conducted by Isolation Systems immediately prior to the Acquisition. The Acquisition was approved by the Board of Directors of the Company, and by the Board of Directors and the stockholders of Isolation Systems.
