("Exodus"), a Delaware Corporation, on the one hand, and Commtouch Software ("Company"), on the other This Agreement is made in reference to the following facts: As of January 9, 2002, Exodus contends that Company owes an outstanding debt to Exodus in the amount of $491,442 as payment for services provided through January 1, 2002 by Exodus to Company in accordance with the terms of the Master Services Agreement, Professional Services Agreement, or Internet Data Center Services Agreement between Exodus and Company dated March 25, 1998 (the "Contract"); and Company disputes its obligation to pay the full amount that Exodus contends it is owed under the Contract; and WHEREAS, it is now the desire and intention of Exodus and Company to settle and resolve all disputes, differences and claims relating to the Contract which exist between them as of the date of this Agreement, with the exception of obligations arising out of this Agreement. NOW, THEREFORE, AND IN CONSIDERATION OF THE MUTUAL PROMISES AND RELEASES CONTAINED HEREIN, THE PARTIES DO HEREBY AGREE AS FOLLOWS: 1. Unless otherwise stated in Exhibit A, Company agrees to pay Exodus the sum of $300,000 on or before January 10, 2002 or the payment shall be deemed untimely. All payments are to be made by via wire transfer to: Wells Fargo Bank, Palo Alto, CA ABA 121000248 ACCT# 4950037887 In the name of Exodus Communications, Inc. 2. In the event of any failure to make a timely payment, as required under Paragraph 1 of this Agreement, Company agrees to pay the amount in Paragraph 1 as well as any and all reasonable attorneys' fees and costs incurred by Exodus in collecting such payment balance from Company. 3. Except for the promises or obligations made or undertaken in this Agreement, upon Exodus' receipt of the last payment required under Paragraph 1 of this Agreement, Exodus and Company, on behalf of themselves and their respective successors and assigns, each hereby releases the other and its current and former officers, directors, shareholders, employees, affiliates, representatives, and agents from any and all claims, demands, and causes of action of any kind whatsoever, whether or not now known, suspected or claimed, which either ever had, now has, or claims to have had relating or connected to, or arising out of, the Contract. These mutual releases apply and extend to all rights, causes of action, or claims asserted, or which could have been asserted, by either party to this Agreement as of the date of this Agreement, irrespective of the theory of recovery that could have been asserted provided, however, that nothing herein shall be deemed to release extracontractual claims or claims or causes of action the Debtors could bring under chapter 5 of the Bankruptcy Code. 4. It is the intention of Exodus and Company in executing this Agreement and in rendering and receiving the consideration called for by this Agreement that this Agreement shall be and is a full and final accord and satisfaction and mutual general release of and from all matters relating to the Contract. 5. Exodus and Company each acknowledges that it is aware of Section 1542 of the Civil Code of the State of California, which provides as follows: A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor. Exodus and Company each waives and relinquishes any right or benefit which it has or may have under Section 1542 of the Civil Code of the State of California. Exodus and Company each acknowledge that they are aware that they or their attorneys or agents may hereafter discover claims or facts in addition to or different from those which they now know or believe to exist with respect to the subject matter of the Contract. Nonetheless, it is their intention fully, finally, and forever to settle and release all disputes and differences relating to the Contract, known or unknown, suspected or unsuspected, which now exist, may exist, or heretofore have existed between them, except as otherwise expressly provided in this Agreement. In furtherance of this intention, the releases herein given shall be and remain in effect as full and complete mutual releases, except as otherwise expressly provided, notwithstanding the discovery or existence of any such additional or different claim or fact. 6.

The language of this Agreement shall be construed as a whole according to its fair meaning, and not strictly for or against one of the parties. 8. Following Exodus' receipt of the payment in Paragraph 1, Company agrees to remove its equipment in accordance with the Contract within five (5) business days of such payment and if not, Exodus is hereby authorized to remove the Company's equipment from the Customer Area (as defined in the Contract) for storage and charge the Company storage fees until the Company's equipment is removed.
