Credit facility.
A.  Purpose.  Advances made under this Line of Credit shall be used
for working capital purposes.

Section 2.02 as the "Variable Rate".)  The Variable Rate shall be
adjusted concurrently with any change in the Reference Rate.
Interest shall be calculated on the basis of 360 days per year but
charged on the actual number of days elapsed.
C.  Payment of Interest.  The Borrower hereby promises and agrees to
pay interest monthly on the first day of each month, commencing on
April 1, 1998.

promises and agrees to pay to the Bank in full the aggregate unpaid
principal balance of all Advances then outstanding, together with
all accrued and unpaid interest thereon.
Any payment received by the Bank shall, at the Bank's option, first
be applied to pay any late fees or other fees then due and unpaid,
and then to interest then due and unpaid and the remainder thereof
(if any) shall be applied to reduce principal.
E.  Late Fee.  If any regularly scheduled payment of principal
and/or interest (exclusive of the final payment upon maturity), or
any portion thereof, under this Line of Credit is not paid within

to five percent (5%) of such past due payment may be assessed and
shall be immediately payable.

hereunder shall be conclusively deemed to have been made at the
request of and for the benefit of the Borrower (i) when credited to

received from the Borrower in form acceptable to the Bank, which
notice shall be received not later than 2:00 p.m. (California Time)
on the date specified for such Advance, which date shall be a

the following fees in connection with this facility:  The Borrower
shall be assessed and shall pay to the Bank each quarter in arrears,

the Bank shall be under no further obligation to advance any monies
thereafter.
I.  Line Account.  The Bank shall maintain on its books a record of
account in which the Bank shall make entries for each Advance and
such other debits and credits as shall be appropriate in connection
with the Line of Credit facility (the "Line Account").  The Bank
shall provide the Borrower with a monthly statement of the
Borrower's Line Account, which statement shall be considered to be
correct and conclusively binding on the Borrower unless the Bank is
notified by the Borrower to the contrary within thirty (30) days
after the Borrower's receipt of any such statement which is deemed
to be incorrect.
J.  Amounts Payable on Demand.  If the Borrower fails to pay on
demand any amount so payable under this Agreement, the Bank may, at
its option and without any obligation to do so and without waiving
any default occasioned by the Borrower's failure to pay such amount,
create an Advance in an amount equal to the amount so payable, which
Advance shall thereafter bear interest as provided under this Line
of Credit facility.
In addition, the Borrower hereby authorizes the Bank, if and to the
extent payment owed to the Bank under this Line of Credit facility
is not made when due, to charge, from time to time, against any or
all of the deposit accounts maintained by the Borrower with the Bank
any amount so due.

Letters of Credit shall, unless earlier terminated in accordance
with the terms of this Agreement, automatically terminate on March
15, 1999 and no Letter of Credit shall expire on a date which is
more than 90 days after such date.
C.  Limitations on Letters of Credit.  Each Letter of Credit shall
be in form and substance and in favor of beneficiaries satisfactory
to the Bank, provided that the Bank may refuse to issue a Letter of
Credit due to the nature of the transaction or its terms or in
connection with any transaction where the Bank, due to the
beneficiary or the nationality or residence of the beneficiary,
would be prohibited by any applicable law, regulation or order from
issuing such Letter of Credit.
D.  Issuance of Letters of Credit.  Prior to the issuance of each
Letter of Credit but in no event later than 10:00 a.m. (California
time) on the day such Letter of Credit is to be issued (which shall

necessary to conduct the Borrower's business as now conducted.
6.08.  Change in Ownership.  There shall occur a sale, transfer,
disposition or encumbrance (whether voluntary or involuntary), or an
agreement shall be entered into to do so, with respect to more than 10%
of the issued and outstanding capital stock of the Borrower.
 
SECTION VII
REMEDIES ON DEFAULT
 
 
 Upon the occurrence of any Event of Default, the Bank may, at its sole
election, without demand and upon only such notice as may be required by
law:
7.01.  Acceleration.  Declare any or all of the Borrower's indebtedness
owing to the Bank, whether under this Agreement or under any other
document, instrument or agreement, immediately due and payable, whether
or not otherwise due and payable.
7.02.  Cease Extending Credit.  Cease making Advances or otherwise
extending credit to or for the account of the Borrower under this
Agreement or under any other agreement now existing or hereafter entered
into between the Borrower and the Bank.
7.03.  Termination.  Terminate this Agreement as to any future
obligation of the Bank without affecting the Borrower's obligations to
the Bank or the Bank's rights and remedies under this Agreement or under
any other document, instrument or agreement.
7.04.  Letters of Credit.  In addition to any other remedies available
to the Bank under this Agreement or otherwise, the Bank may require the
Borrower to pay immediately to the Bank, for application against any
drawings under any outstanding Letters of Credit, the outstanding
principal amount of any such Letters of Credit which have not expired.
Any portion of the amount so paid to the Bank which is not applied to
satisfy draws under any such Letters of Credit or any other obligations
of the Borrower to the Bank shall be repaid to the Borrower without
interest.
7.05.  Non-Exclusivity of Remedies.  Exercise one or more of the Bank's
rights set forth herein or seek such other rights or pursue such other
remedies as may be provided by law, in equity or in any other agreement
now existing or hereafter entered into between the Borrower and the
Bank, or otherwise.
 
SECTION VIII
MISCELLANEOUS PROVISIONS
 
 
8.01.  Default Interest Rate.  If an Event of Default has occurred and
is continuing, the Bank, at its option, may require the Borrower to pay
to the Bank interest on any Indebtedness or amount payable under this
Agreement at a rate which is 3% in excess of the rate or rates otherwise
then in effect under this Agreement.
8.02.  Reimbursement of Certain Costs in Connection With Letters of
Credit.  The Borrower shall, upon the Bank's request, promptly pay to
and reimburse the Bank for all costs incurred and payments made by the
Bank by reason of any future assessment, reserve, deposit or similar
requirement or any surcharge, tax or fee imposed upon the Bank or as a
result of the Bank's compliance with any directive or requirement of any
regulatory authority pertaining or relating to any Letters of Credit.
8.03.  Reliance.  Each warranty, representation, covenant and agreement
contained in this Agreement shall be conclusively presumed to have been
relied upon by the Bank regardless of any investigation made or
information possessed by the Bank and shall be cumulative and in
addition to any other warranties, representations, covenants or
agreements which the Borrower shall now or hereafter give, or cause to
be given, to the Bank.
8.04.  Dispute Resolution.
A.  Disputes.  It is understood and agreed that, upon the request of
any party to this Agreement, any dispute, claim or controversy of
any kind, whether in contract or in tort, statutory or common law,
legal or equitable, now existing or hereinafter arising between the
parties in any way arising out of, pertaining to or in connection
with: (i) this Agreement, or any related agreements, documents or
instruments, (ii) all past and present loans, credits, accounts,
deposit accounts (whether demand deposits or time deposits), safe
deposit boxes, safekeeping agreements, guarantees, letters of
credit, goods or services, or other transactions, contracts or
agreements of any kind, (iii) any incidents, omissions, acts,
practices, or occurrences causing injury to any party whereby
another party or its agents, employees or representatives may be
liable, in whole or in part, or (iv) any aspect of the past or
present relationships of the parties, shall be resolved through a
two-step dispute resolution process administered by the Judicial
Arbitration & Mediation Services, Inc. ("JAMS") as follows:
B.  Step I - Mediation.  At the request of any party to the dispute,
claim or controversy, the matter shall be referred to the nearest
office of JAMS for mediation, which is an informal, non-binding
conference or conferences between the parties in which a retired
judge or justice from the JAMS panel will seek to guide the parties
to a resolution of the case.
C.  Step II - Arbitration (Contracts Not Secured By Real Property).
Should any dispute, claim or controversy remain unresolved at the
conclusion of the Step I Mediation Phase, then (subject to the
restriction at the end of this subparagraph) all such remaining
matters shall be resolved by final and binding arbitration before a
different judicial panelist, unless the parties shall agree to have
the mediator panelist act as arbitrator.  The hearing shall be
conducted at a location determined by the arbitrator in Los Angeles,
California (or such other city as may be agreed upon by the parties)
and shall be administered by and in accordance with the then
existing Rules of Practice and Procedure of JAMS and judgement upon
any award rendered by the arbitrator may be entered by any State or
Federal Court having jurisdiction thereof.  The arbitrator shall
determine which is the prevailing party and shall include in the
award that party's reasonable attorneys' fees and costs.  This
subparagraph shall apply only if, at the time of the submission of
the matter to JAMS, the dispute or issues involved do not arise out
of any transaction which is secured by real property collateral or,
if so secured, all parties consent to such submission.
As soon as practicable after selection of the arbitrator, the
arbitrator, or the arbitrator's designated representative, shall
determine a reasonable estimate of anticipated fees and costs of the
arbitrator, and render a statement to each party setting forth that
party's pro-rata share of said fees and costs.  Thereafter, each
party shall, within 10 days of receipt of said statement, deposit
said sum with the arbitrator.  Failure of any party to make such a
deposit shall result in a forfeiture by the non-depositing party of
the right to prosecute or defend the claim which is the subject of
the arbitration, but shall not otherwise serve to abate, stay or
suspend the arbitration proceedings.
D.  Step II - Trial By Court Reference (Contracts Secured By Real
Property).  If the dispute, claim or controversy is not one required
or agreed to be submitted to arbitration, as provided in the above
subparagraph, and has not been resolved by Step I mediation, then
any remaining dispute, claim or controversy shall be submitted for
determination by a trial on Order of Reference conducted by a
retired judge or justice from the panel of JAMS appointed pursuant
to the provisions of Section 638(1) of the California Code of Civil
Procedure, or any amendment, addition or successor section thereto,
to hear the case and report a statement of decision thereon.  The
parties intend this general reference agreement to be specifically
enforceable in accordance with said section.  If the parties are
unable to agree upon a member of the JAMS panel to act as referee,
then one shall be appointed by the Presiding Judge of the county
wherein the hearing is to be held.  The parties shall pay in
advance, to the referee, the estimated reasonable fees and costs of
the reference, as may be specified in advance by the referee.  The
parties shall initially share equally, by paying their proportionate
amount of the estimated fees and costs of the reference.  Failure of
any party to make such a fee deposit shall result in a forfeiture by
the non-depositing party of the right to prosecute or defend any
cause of action which is the subject of the reference, but shall not
otherwise serve to abate, stay or suspend the reference proceeding.
E.  Provisional Remedies, Self Help and Foreclosure.  No provision
of, or the exercise of any rights under any portion of this Dispute
Resolution provision, shall limit the right of any party to exercise
self help remedies such as set off, foreclosure against any real or
personal property collateral, or the obtaining of provisional or
ancillary remedies, such as injunctive relief or the appointment of
a receiver, from any court having jurisdiction before, during or
after the pendency of any arbitration.  At the Bank's option,
foreclosure under a deed of trust or mortgage may be accomplished
either by exercise of power of sale under the deed of trust or
mortgage, or by judicial foreclosure.  The institution and
maintenance of an action for provisional remedies, pursuit of
provisional or ancillary remedies or exercise of self help remedies
shall not constitute a waiver of the right of any party to submit
the controversy or claim to arbitration.
8.05.  Waiver of Jury.  The Borrower and the Bank hereby expressly and
voluntarily waive any and all rights, whether arising under the
California constitution, any rules of the California Code of Civil
Procedure, common law or otherwise, to demand a trial by jury in any
action, matter, claim or cause of action whatsoever arising out of or in
any way related to this Agreement or any other agreement, document or
transaction contemplated hereby.
8.06.  Restructuring Expenses.  In the event the Bank and the Borrower
negotiate for, or enter into, any restructuring, modification or
refinancing of the Indebtedness under this Agreement for the purposes of
remedying an Event of Default, The Bank, may require the Borrower to
reimburse all of the Bank's costs and expenses incurred in connection
therewith, including, but not limited to reasonable attorneys' fees and
the costs of any audit or appraisals required by the Bank to be
performed in connection with such restructuring, modification or
refinancing.
8.07.  Attorneys' Fees.  In the event of any suit, mediation,
arbitration or other action in relation to this Agreement or any
document, instrument or agreement executed with respect to, evidencing
or securing the indebtedness hereunder, the prevailing party, in
addition to all other sums to which it may be entitled, shall be
entitled to reasonable attorneys' fees.
8.08.  Notices.  All notices, payments, requests, information and
demands which either party hereto may desire, or may be required to give
or make to the other party shall be given or made to such party by hand
delivery or through deposit in the United States mail, postage prepaid,
or by Western Union telegram, addressed to the address set forth below
such party's signature to this Agreement or to such other address as may
be specified from time to time in writing by either party to the other.
8.09.  Waiver.  Neither the failure nor delay by the Bank in exercising
any right hereunder or under any document, instrument or agreement
mentioned herein shall operate as a waiver thereof, nor shall any single
or partial exercise of any right hereunder or under any document,
instrument or agreement mentioned herein preclude other or further
exercise thereof or the exercise of any other right; nor shall any
waiver of any right or default hereunder or under any other document,
instrument or agreement mentioned herein constitute a waiver of any
other right or default or constitute a waiver of any other default of
the same or any other term or provision.
8.10.  Conflicting Provisions.  To the extent that any of the terms or
provisions contained in this Agreement are inconsistent with those
contained in any other document, instrument or agreement executed
pursuant hereto, the terms and provisions contained herein shall
control.  Otherwise, such provisions shall be considered cumulative.
8.11.  Binding Effect; Assignment.  This Agreement shall be binding upon
and inure to the benefit of the Borrower and the Bank and their
respective successors and assigns, except that the Borrower shall not
have the right to assign its rights hereunder or any interest herein
without the Bank's prior written consent.  The Bank may sell, assign or
grant participations in all or any portion of its rights and benefits
hereunder.  The Borrower agrees that, in connection with any such sale,
grant or assignment, the Bank may deliver to the prospective buyer,
participant or assignee financial statements and other relevant
information relating to the Borrower and any guarantor.
8.12.  Jurisdiction.  This Agreement, any notes issued hereunder, and
any documents, instruments or agreements mentioned or referred to herein
shall be governed by and construed according to the laws of the State of
California, to the jurisdiction of whose courts the parties hereby
submit.
8.13.  Headings.  The headings set forth herein are solely for the
purpose of identification and have no legal significance.
8.14.  Entire Agreement.  This Agreement and all documents, instruments
and agreements mentioned herein constitute the entire and complete
understanding of the parties with respect to the transactions
contemplated hereunder.  All previous conversations, memoranda and
writings between the parties or pertaining to the transactions
contemplated hereunder that are not incorporated or referenced in this
Agreement or in such documents, instruments and agreements are
superseded hereby.
 
 
IN WITNESS WHEREOF, this Agreement has been executed by the parties
hereto as of the date first hereinabove written.
