appointment of a receiver, or the exercise of other provisional remedies (any
and all of which may be initiated pursuant to applicable law), each controversy,
dispute or claim between the parties arising out of or relating to the Loan
Documents, which controversy, dispute or claim is not settled in writing within
thirty (30) days after the "Claim Date" (defined as the date on which a party
subject to the Loan Documents gives written notice to all other parties that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 et seq. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning the Loan Documents, including whether such
controversy, dispute or claim is subject to the reference proceeding and except
as set forth above, the parties waive their rights to initiate any legal
proceedings against each other in any court or jurisdiction other than the
Superior Court in the County where the Real Property, if any, is located or Los
Angeles County if none (the "Court"). The referee shall be a retired Judge of
the Court selected by mutual agreement of the parties, and if they cannot so
agree within forty-five (45) days after the Claim Date, the referee shall be
promptly selected by the Presiding Judge of the Court (or his representative).
The referee shall be appointed to sit as a temporary judge, with all of the
powers for a temporary judge, as authorized by law, and upon selection should
take and subscribe to the oath of office as provided for in Rule 244 of the
California Rules of Court (or any subsequently enacted Rule). Each party shall
have one peremptory challenge pursuant to CCP ss.170.6. The referee shall (a) be
requested to set the matter for hearing within sixty (60) days after the Claim
Date and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date. Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP ss.644 in any court in the State of
California having jurisdiction. Any party may apply for a reference proceeding
at any time after thirty (30) days following notice to any other party of the
nature of the controversy, dispute or claim, by filing a petition for a hearing
and/or trial. All discovery permitted by this Agreement shall be completed no
later than fifteen (15) days before the first hearing date established by the
referee. The referee may extend such period in the event of a party's refusal to
provide requested discovery for any reason whatsoever, including, without
limitation, legal objections raised to such discovery or unavailability of a
witness due to absence or illness. No party shall be entitled to "priority" in
conducting discovery. Depositions may be taken by either party upon seven (7)
days written notice, and request for production or inspection of documents shall
be responded to within ten (10) days after service. All disputes relating to
discovery which cannot be resolved by the parties shall be submitted to the
referee whose decision shall be final and binding upon the parties. Pending
appointment of the referee as provided herein, the Superior Court is empowered
to issue temporary and/or provisional remedies, as appropriate.



                                                                              7

<PAGE>   8

        b. Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with respect to the course of the reference
proceeding. All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter except that when any
party so requests, a court reporter will be used at any hearing conducted before
the referee. The party making such a request shall have the obligation to
arrange for and pay for the court reporter. The costs of the court reporter at
the trial shall be borne equally by the parties.

        c. The referee shall be required to determine all issues in accordance
with existing case law and the statutory laws of the State of California. The
rules of evidence applicable to proceedings at law in the State of California
will be applicable to the reference proceeding. The referee shall be empowered
to enter equitable as well as legal relief, to provide all temporary and/or
provisional remedies and to enter equitable orders that will be binding upon the
parties. The referee shall issue a single judgment at the close of the reference
proceeding which shall dispose of all of the claims of the parties that are the
subject of the reference. The parties hereto expressly reserve the right to
contest or appeal from the final judgment or any appealable order or appealable
judgment entered by the referee. The parties hereto expressly reserve the right
to findings of fact, conclusions of laws, a written statement of decision, and
the right to move for a new trial or a different judgment, which new trial, if
granted, is also to be a reference proceeding under this provision.

        d. In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration. The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, ss.1280 through ss.1294.2 of the CCP as
amended from time to time. The limitations with respect to discovery as set
forth hereinabove shall apply to any such arbitration proceeding.

This Agreement is executed on behalf of the parties by duly authorized
representatives as of _____, 19__.
