5.2 Confidentiality. Except as otherwise required in the performance of obligations under this Agreement and except as otherwise required by law, any nonpublic information received by a party or its advisors from the other party shall be kept confidential and shall not be used or disclosed for any purpose other than in furtherance of the transactions contemplated by this Agreement. The obligation of confidentiality shall not extend to information (a) which is or shall become generally available to the public other than as a result of an unauthorized disclosure by a party to this Agreement or a person to whom a party has provided such information, (b) which is or becomes known by or available to a party to this Agreement on a nonconfidential basis prior to its disclosure by one party to the other pursuant to this Agreement, or (c) which is or becomes available to a party on a nonconfidential basis from a source other than a party to this Agreement. Upon termination of this Agreement, each party shall promptly return any confidential information received from the other party and, upon request, shall destroy any copies of such information in its possession. The covenants of the parties contained in this Section 5.2 shall survive any termination of this Agreement.

5.3 Notification. Each party to this Agreement shall promptly notify the other parties in writing of the occurrence, or pending or threatened occurrence, of any event that would constitute a breach or violation of this Agreement by any party or that would cause any representation or warranty made by the notifying party in this Agreement to be false or misleading in any respect. Any such notification shall not limit or alter any of the representations, warranties or covenants of the parties set forth in this Agreement nor any rights or remedies a party may have with respect to a breach of any representation, warranty or covenant.

5.4 Further Assurances. The parties hereto shall deliver any and all other instruments or documents required to be delivered pursuant to, or necessary or proper in order to give effect to, all of the terms and provisions of this Agreement including, without limitation, all necessary stock powers and such other instruments of transfer as may be necessary or desirable to transfer ownership of the DOC Shares or the ADSX Exchange Shares and to consummate the transactions contemplated by this Agreement.

ARTICLE VI

Additional Agreements

6.1 Survival of the Representations and Warranties. The representations and warranties of ADSX and of DOC set forth in this Agreement shall terminate immediately following the Closing Date (or any alternative closing date).

6.2 Investigation. The representations, warranties, covenants and agreements set forth in this Agreement shall not be affected or diminished in any way by any investigation (or failure to investigate) at any time by or on behalf of the party for whose benefit such representations, warranties, covenants and agreements were made. All statements contained herein or in any schedule, certificate, exhibit, list or other document delivered pursuant hereto or in connection with the transactions contemplated hereby shall be deemed to be representations and warranties for purposes of this Agreement.

6.3 Arbitration. Any and all claims, disputes or matters in controversy arising under this Agreement which the parties are unable to settle by mutual agreement shall be resolved by binding arbitration pursuant to the Commercial Arbitration Rules of the American Arbitration Association as in force at the time (“AAA”).

(a) A party which desires to submit a claim, dispute or controversy to binding arbitration under this Section 6.3 shall so notify the other parties, and if after 30 days from the date of such notice the claim, dispute or controversy remains unsettled, any party may petition the AAA for arbitration of the claim, dispute or controversy. Matters submitted to arbitration shall be resolved in accordance with the decision of a panel of three arbitrators selected by the AAA. The arbitrators shall be experienced in the resolution of commercial disputes arising in the context of negotiated acquisitions of businesses, and the place of arbitration shall be either West Palm Beach or Delray Beach, Florida.

(b) The three arbitrators shall investigate the facts and shall hold hearings at which the parties to this Agreement may present evidence and arguments, be represented by counsel and conduct cross-examination. In determining any question, matter or dispute before them, the arbitrators shall apply the provisions of this Agreement and shall not have the power to add to, modify or change any of the provisions of this Agreement. The three arbitrators shall render a written decision upon the matter presented to them by a majority vote within 90 days after the date on which the hearings and presentation of evidence are concluded, unless a longer period is provided under the rules of the AAA. The decision rendered by the arbitrators shall be final and binding on, and unappealable by, the parties. Judgment upon the decision rendered in such arbitration may be entered by any court having jurisdiction thereof. No party to an arbitration proceeding shall be considered in default hereunder during the pendency of arbitration proceedings relating to a disputed default. If the three arbitrators fail to render a timely decision, then, to the extent permitted by law, any party shall have the right to institute an action or proceeding in such court as shall be appropriate in the circumstances, and, upon the institution of such action, the arbitration proceeding shall be terminated and shall be of no further force and effect. The arbitrators shall determine in what proportion the parties shall bear the fees and expenses of the arbitrators, and each party shall otherwise bear its own fees and expenses, including expenses of legal counsel and other advisors or consultants. It is the intention of the parties that arbitration as described above be the sole and exclusive means available to them for the resolution of claims, disputes or matters in controversy arising under this Agreement, other than claims, disputes and matters arising under those provisions referred to in the first sentence of this Section 6.3, and only in the event that the arbitrators fail to render a decision in accordance with the foregoing provisions shall a party have the right to institute legal action with respect to such claim, dispute or matter. Accordingly, it shall be a complete defense to any action instituted by a party with respect to a claim, dispute or matter in controversy under this Agreement that such claim, dispute or matter has not first been submitted to arbitration in accordance with the foregoing provisions.
