them, as set forth above, from any and all Claims, including those that are
unknown, unsuspected or unforeseen or that are presently unknown and
unanticipated.

It is understood and agreed that the releases as referred to herein are full and
final releases by Employer of Employee, and that such full and final releases
include, without limitation, all unknown and unanticipated claims, injuries,
debts, or damages, as well as those now known or disclosed. With respect to any
claims by Employer against Employee, Employer expressly waives the Provisions of
California Civil Code section 1542 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."

obligations of the parties under this Agreement shall be conclusively determined
by binding arbitration, The arbitration shall be conducted as follows:

      8.1 Binding Arbitration. Any dispute between the parties shall be
submitted to, and conclusively determined by, binding arbitration in accordance
with this paragraph. The provisions of this paragraph shall not preclude any
party from seeking injunctive or other provisional or equitable relief in order
to preserve the status quo of the parties pending resolution of the dispute, and
the filing of an action seeking injunctive or other provisional relief shall not
be construed as a waiver of that party's arbitration rights. The arbitration of
any dispute between the parties to this Agreement shall be governed by the
provisions of the California Arbitration Act (California Code of Civil Procedure
section 1280 et seq., including the provisions contained in section 1283.05).

      8.2 Initiation of Arbitration. In the case of any dispute between the
parties to this Agreement, either party shall have the right to initiate the
binding arbitration process provided for in this paragraph by serving upon the
other party a demand for arbitration. Notwithstanding any other provision of
law, in order to be enforceable a demand for arbitration must be served within
sixty (60) days of the date on which a party discovers or reasonably should have
discovered, facts giving rise to a dispute as defined above.

      8.3 Selection of Arbitrators. Within thirty (30) days of service of a
demand for arbitration by either party to this Agreement, the parties shall
endeavor in good faith to select a single arbitrator. If they fail to do so
within that time period, each party shall have an additional period of fifteen
(15) days in which to appoint an arbitrator and those arbitrators within fifteen
(15) days shall select an additional arbitrator. If any party fails to appoint
an arbitrator or if the arbitrators initially selected by the parties fail to
appoint an additional arbitrator within the time specified herein, any party may
apply to have an arbitrator appointed for the party who has failed to appoint,
or to have the additional arbitrator appointed, by the presiding judge for the
Superior Court, Sutter County, California. If the presiding judge, acting in his
or her personal capacity, is unable or unwilling to appoint the additional

motions prior to the taking of evidence on the merits of the dispute. By way of
example, such dispositive motions would include, but not be limited to, those
which would entitle a party to summary judgement or summary adjudication of
issues pursuant to Code of Civil Procedure section 437c or resolution of a
special defense as provided for at Code of Civil Procedure section 597. In the
event a party to the arbitration requests that the arbitrators resolve a
dispositive motion, the arbitrators shall receive and consider any written or
oral arguments regarding the dispositive motion, and shall receive and consider
any evidence specifically relating thereto, and shall render a decision thereon,
before hearing any evidence on the merits of the dispute. The arbitration shall
proceed with due dispatch and a decision shall be rendered within sixty (60)
days after the appointment of the final arbitrator. Such decision shall be in
such written form that a judgment may be entered on it in any court of competent
jurisdiction in the State of California.

      8.7 Limitation on Scope of Arbitrators' Award or Decision. Employer and
Employee agree that if the arbitrators find any disputed claim to be
meritorious, the arbitrators shall have the authority to order legal and/or
equitable relief appropriate to the claim.

      8.8 Costs of Arbitration; Attorneys' Fees. While the arbitration is
pending, each party shall bear equally the costs of the arbitration and shall
bear its own attorneys' fees. However, at the conclusion of the arbitration,

party the costs, including the costs of the arbitration, and attorneys' fees
incurred by that party in participating in the arbitration process.
