 AGREEMENT
  1.  Purpose of this
Agreement.
  This Agreement is intended as a full
and final settlement and compromise of any and all Claims (as that term is
defined hereinafter) that any Primal Party, on the one hand, and any CyberSource
Party, on the other hand, has or may have against the other arising out of,
concerning, pertaining to or otherwise connected with the subject matter of this
Agreement.  Neither this Agreement nor any of its terms is admissible
in any proceeding among or between any Primal Party, on the one hand, and any
CyberSource Party, on the other hand, except in a proceeding to interpret or
enforce its terms.  It is the intention of the Parties that this
Agreement shall be effective as a full and final accord and satisfaction of any
and all Claims  among or between any Primal Party, on the one hand,
and any CyberSource Party, on the other hand (including, without limitation,
those obligations arising under the Loan Documents).
  2.  Payment and Other
Consideration.
  A.           Primal
shall pay and deliver or cause to be paid and delivered to CyberSource in
immediately available funds in the form of either a certified check or wire
transfer the sum of ONE HUNDRED THOUSAND DOLLARS (USD$100,000.00) (the “Settlement Amount”),
within five (5) business days of the date on which the last Party to execute
this Agreement signs this Agreement and provides a fully-executed signature page
to the other Parties.
  B.           The
above payment by Primal shall be accepted by CyberSource in full settlement and
satisfaction of all obligations of any and all Primal Parties pursuant to the
Loan Documents and any and all other obligations of any kind whatsoever owed by
any Primal Party to any CyberSource Party or its predecessors in
interest.
  C.           The
CyberSource Parties’ releases as more particularly set forth in Section 3,
below, are expressly conditioned on receipt of the Settlement
Amount.   Upon receipt of the Settlement Amount, CyberSource
promptly shall deliver or cause to be delivered to Primal for cancellation
originals or copies of each of the Loan Documents, to the extent such documents
have not previously been delivered to a Primal Party for cancellation; provided
that in the event CyberSource is not able to locate and, therefore, does not
return all of the originals of the Loan Documents to Primal, the Primal Parties
and CyberSource Parties hereby deem any and all unreturned originals to have
been canceled and of no further force and effect.
  D.           Effective
immediately upon receipt by CyberSource of the Settlement Amount, each
CyberSource Party hereby releases and terminates any and all of its interest in
the security interests it had, has or may have upon any assets (real and
personal) of any Primal Party (including, without limitation, any security
interests it has pursuant to the Security Agreement).  The CyberSource
Parties agree that, upon the effectiveness of such releases, it hereby grants to
the Primal Parties the right and authority to take, or cause to be taken, at the
Primal Parties’ sole cost and expense, all appropriate action, and to do, or
cause to be done, all things reasonably necessary, proper, or advisable in order
to effectuate such release and termination (including, without limitation,
approving and/or signing any termination statement necessary to release the
financing statement and other UCC filings previously filed with the California
Secretary of State, the United States Patent and Trademark Office, or any
similar governmental authority) and make effective the provisions of this
Agreement.

Claims.

an Insolvency
 3
 Event (as
hereinafter defined) during such one hundred (100)-day period; or (ii) if an
Insolvency Event has occurred within such 100 days, the date that any and all
limitations periods for an action for the avoidance of the payment has passed
without any such action’s having been commenced, each of the CyberSource
Parties, for itself and its respective predecessors, successors, assigns,
attorneys and other representatives, hereby releases and forever discharges each

law, statutory or otherwise), whether known or unknown, fixed or contingent,
anticipated or unanticipated, which any such releasing party has, may have, or
may hereafter have or claim to have, against any of them respecting anything
whatsoever done or omitted to be done on or prior to the date of this Agreement,
based on, arising out of, or in connection with (a) the Loan Documents and (b)
any and all other contracts, agreements, arrangements, or obligations among or

trustee, receiver, liquidator, custodian, or other similar official of it or any

current and former partners, members, agents, parents, subsidiaries,

affiliates, attorneys and other representatives, and each of the CyberSource
Parties, for itself and its respective predecessors, successors, assigns,

its respective predecessors, successors, assigns, affiliates, attorneys and
other representatives, and each of the CyberSource Parties, for itself and its
respective predecessors, successors, assigns, affiliates, attorneys and other

suspected or unsuspected, which they may have had, may have or may hereafter
