(7) days of payment in full of the Revised December Payment, ClickAction shall file a termination statement with the California Secretary of State sufficient to terminate ClickActions second priority security interest in the Purchased Assets

4.    General Release by the Parties.    Elibrium and ClickAction, on behalf of themselves and their past and present officers, stockholders, directors, agents,
employees, predecessors, successors, assigns and Affiliates (collectively, the Related Parties), each hereby





(a)  release and forever discharge the other party and such partys Related Parties of and from any and all known and unknown claims, debts, liabilities, costs, actions, demands, contracts, suits,
expenses, damages, actions and causes of action of any kind or nature which the releasing party and/or any of its Related Parties may now have or may now claim to have against the other party or any of its Related Parties which in any way arise out
of the transactions contemplated by the Purchase Agreement, including, without limitation, any known and unknown claims, debts, liabilities, costs, actions, demands, contracts, suits, expenses, damages, actions and causes of action of any kind or
nature relating, directly or indirectly, to the Dispute;

out of the Purchase Agreement, whether the same are known, unknown or hereafter discovered or ascertained but which exist as of the date hereof. The parties acknowledge that they have been advised by legal counsel and are familiar with the
provisions of California Civil Code Section 1542, which provides as follows:

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.





The parties, being aware of said Code Section, hereby expressly, knowingly and intentionally waive any rights they may have thereunder, as well as under any other statute or common law principles of similar
effect.





6.    Assumption of Liabilities.    Notwithstanding anything to the
contrary in the Purchase Agreement, Elibrium hereby agrees, as of the Effective Date, to assume, pay, perform and discharge any and all liabilities or obligations arising from or related to the Purchased Assets, regardless of whether such
liabilities or obligations arose or accrued before, on or after the Closing Date (the Assumed Liabilities). Elibrium hereby further agrees to indemnify ClickAction and each of its Related Parties against, and agrees to hold
each of them harmless from, any and all Losses incurred or suffered by them relating to or arising from the Assumed Obligations in accordance with the indemnification procedures set forth in Article XIII of the Purchase Agreement.





7.Effect of this Agreement.    Nothing in this Agreement shall be deemed to release either
party hereto from (a) any obligations incurred or specified under this Agreement or (b) any claims under the Purchase Agreement as amended hereby accruing subsequent to the date of this Agreement. In the event and to the extent that there is a
conflict between the provisions of this Agreement and the provisions of the Purchase Agreement, this Agreement shall prevail.

after this Agreement is executed or in the absence of this Agreement; provided, however, that ClickAction shall have the right to issue any press release it reasonably deems necessary to comply with its obligations under the Securities Exchange Act
of 1934, as amended, and any other applicable laws if Elibrium fails to timely make any of the payments set forth in Section 2 above or otherwise breaches this Agreement.

charter documents or cause a breach under any other instrument or contract to which it is a party, (c) it has duly and validly executed and delivered this Agreement and (d) this Agreement is a legal, valid and binding obligation of such party,
enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors rights generally and general equity principles.

between the parties regarding settlement of their claims relating to the Purchase Agreement and supersedes any and all prior and contemporaneous agreements, representations and negotiations, including, without limitation, the Preliminary Settlement
Agreement, dated as of December 16, 2001, between ClickAction and Elibrium.
