22. Arbitration.

(a) Resolution of Disputes. The parties will submit all controversies, disputes or claims among them arising out of or relating to this agreement, the transactions contemplated hereby or the Assignment to binding arbitration as provided below. The rules governing the arbitration and all related preliminary proceedings will be agreed upon by the parties. If they are unable to agree on those rules within 30 days of written request for agreement, the Rules for Commercial Arbitration of the American Arbitration Association ("AAA"), as amended from time to time and as modified by this Agreement, will control. The dispute will be presented to a. single arbitrator (the "Arbitrator"), sitting in San Diego, California.

(b) Selection of the Arbitrator. The parties will jointly select the Arbitrator within fifteen (15) days after demand for arbitration is made by a party. If the parties are unable to agree on an Arbitrator within that period, then any party may request that the AAA select the Arbitrator in accordance with its then existing rules for doing so. The Arbitrator must possess substantive legal experience in the principal issues in dispute.

(c) Discovery. Any discovery permitted shall be limited to information directly relevant to the controversy in arbitration. In the event of discovery disputes, the Arbitrator is directed to issue orders as are appropriate to limit discovery in accordance with the foregoing and as are reasonable in light of the issues in dispute, the amount in controversy, and other relevant considerations. To the extent the parties are unable to agree on the scope of discovery, the Arbitrator will require the party seeking discovery on an issue to present the legal and factual basis for the dispute and will permit the party opposing discovery to respond. The Arbitrator will permit discovery on an issue only if he or she concludes that there is a reasonable and good faith basis in law and in fact for bringing the allegations and that the discovery appears likely to present substantive evidence regarding that dispute. The Arbitrator may allow limited discovery to permit investigation of some of the disputes or to determine whether a claim has sufficient basis in law or in fact to warrant further discovery. The Arbitrator, however, will issue appropriate orders to restrict the scope of that discovery. The federal or state rules of procedure and evidence will not apply to the arbitration proceedings, including the rules of discovery. The Arbitrator will consider claims of privilege, work product and other restrictions on discovery as appear to be warranted. (d) Fees. The Arbitrator will award the prevailing party its attorney's and experts' fees and disbursements incurred in resolving the dispute and will award double costs and expenses or other sanctions to the extent the Arbitrator finds any dispute advanced in the proceedings to be frivolous or without a good faith basis in fact and in Law when the dispute was first presented for arbitration.

(e) Award/Consent to Jurisdiction. Except as may otherwise be agreed in writing by the parties or as ordered by the Arbitrator upon substantial justification shown, the hearing for the dispute will be held within ninety (90) days of submission of the dispute to arbitration. The Arbitrator will render a final award within thirty (30) days following conclusion of the hearing and any required post-hearing briefing or other proceedings ordered by the Arbitrator. The Arbitrator will state the factual and legal basis for the award. The decision of the Arbitrator will be final and binding, except as provided in the Federal Arbitration Act, 9 U.S.C. 1, et seq., and except for errors of law based on the findings of fact. Final judgment may be entered upon the award in any court of competent jurisdiction but entry of judgment will not be required to make the award effective. By signing below, the parties irrevocably submit to the exclusive jurisdiction and venue of the state and federal courts and arbitration forums located in San Diego, California.

23. MUTUAL WAIVER OF RIGHT TO JURY TRIAL. SELLER, PURCHASER AND BORROWER EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (i) THIS AGREEMENT; OR (ii) THE ASSIGNMENT OR (iii) ANY OTHER PRESENT OR FUTURE INSTRUMENT OR AGREEMENT AMONG SELLER, PURCHASER AND BORROWER; OR (iii) ANY CONDUCT, ACTS OR OMISSIONS OF SELLER, PURCHASER OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SELLER, PURCHASER OR BORROWER; IN EACH OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.
