                           (c). Confidentiality; Public Announcements.

(i). The Parties undertake with each other that they shall treat as strictly confidential all information received or obtained by them or their employees, agents or advisers in connection with the entry into or the performance of this Agreement including information relating to the provisions of this Agreement, the negotiations leading up to this Agreement, the subject matter of this Agreement, and the business or affairs of any other Party and subject to the provisions of this section that they will not at any time hereafter make use of or disclose or divulge to any Person any such information and shall use all reasonable efforts to prevent the publication or disclosure of any such information.

(ii). The restrictions contained in this section shall not: (A) apply to any disclosure which, pursuant to relevant Laws and rules, any governmental authority requires any Party to make, provided that written consent as to the form and content (which consent shall not be unreasonably withheld) of the other Party has been obtained prior to any disclosure of information in public announcement involving such other Party; (B) restrict or prohibit any Party in or from making any disclosure to any professional adviser for the purposes of obtaining necessary professional advice; provided such Party shall procure that such professional adviser observes the confidentiality obligation set forth in this section; and (C) apply to information which was in the public domain or otherwise known to the relevant Party before it was furnished to it by another Party hereto or, after it was furnished to that Party, entered the public domain otherwise than as a result of a breach by that Party of this section or a breach of a confidentiality obligation by the disclosing Party, where the breach was known to that Party.

(iii). No Party shall make, nor shall cause to be made, any press release or public announcement in respect of this Agreement, the identity of the parties to this Agreement or the transactions contemplated thereby or otherwise communicate with any news media without the prior written consent of the other Party, unless otherwise required by Law or applicable stock exchange regulation (and then only after consultation with the other Party), and the Parties shall cooperate as to the timing and contents of any such press release, public announcement or communication.  In the event that any Party or any of his agents, representatives, Affiliates, or employees becomes legally compelled to disclose any such confidential information, such Party shall provide the other Party with prompt written notice of such requirement so that such other Party may seek a protective order or other remedy, or provide a written consent as to the form and content of the disclosure (which consent shall not be unreasonably withheld) of the other Party prior to any such disclosure of confidential information.  In the event that such protective order or other remedy is not obtained, or such other Party waives compliance with this section, the Party legally compelled to disclose such confidential information shall furnish only that portion of such confidential information which is legally required to be provided and exercise all reasonable efforts to obtain assurances that confidential treatment will be accorded to such information.

            (d). Severability.  If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

            (e). Entire Agreement.  This Agreement constitutes the entire agreement of the Parties with respect to the subject matter hereof and thereof and supersedes all prior agreements and undertakings, both written and oral, among the Parties with respect to the subject matter hereof and thereof.

            (f). Assignment.  This Agreement may not be assigned by operation of law or otherwise without the express written consent of the Parties (which consent may be granted or withheld in the sole discretion of the Parties) and any such assignment or attempted assignment without such consent shall be void.

           (g). Amendment.  This Agreement may not be amended or modified except by an instrument in writing signed by all of the Parties, or by a waiver in accordance with this Agreement.

           (h). Waiver.  Any Party to this Agreement may: (i) extend the time for the performance of any of the obligations or other acts of any other Party; (ii) waive any inaccuracies in the representations and warranties of any other Party contained herein or in any document delivered by such other Party pursuant hereto; or (iii) waive compliance with any of the agreements of any other Party or conditions to such Party's obligations contained herein.  Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the Party to be bound thereby.  Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement.  The failure of any Party to assert any of his rights hereunder shall not constitute a waiver of any of such rights.  All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

           (i). Successors and Assigns.  This Agreement shall be binding upon and inure solely to the benefit of the Parties and their respective successors and permitted assigns.

           (j). Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction).

           (k). Counterparts.  This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

           (l). Further Assurances.  Each of the Parties shall, from time to time at the request of the other Party, furnish the other Party such further information or assurances, execute and deliver such additional documents, instruments and conveyances, and take such other actions and do such other things, as may be necessary or desirable to carry out the provisions of this Agreement and give effect to the transactions contemplated hereby, including without limitation any assignment instruments, joinders or agreements to be bound by the Agreements or the Securities.
