Unless otherwise agreed by Bank and Borrower, any Loan requested by Borrower

Bank.

     Bank shall maintain an account on its books in the name of Borrower
(the "Loan Account") on which Borrower will be charged with all Loans and
Letters of Credit Fees and reimbursement obligations, and any other payment
obligations of Borrower.  In accordance with Section 2.6 and 2.13, the Loan

substantially in the form of Exhibit B hereto, in the maximum amount of Loans
available under the Commitment as originally in effect and dated as of the
date of this Agreement.  The Bank shall enter in its records the amount of

the Prime Rate changes.

Prime Rate plus three percent (3) %.

          (c)     Interest under Section 2.4(a) shall be

charge all principal and interest on Loans, and all Letter of Credit
Obligations, to the Loan Account using Bank's auto-debit system.  Whenever
any payment to be made hereunder shall be stated to be due on a day which is
not a Business Day, such payment shall be made on the next succeeding
Business Day and such extension of time shall be included in the computation
of any interest or fees.  In the event that there are insufficient funds in
the Loan Account for payment of such amounts, Borrower hereby authorizes
Bank, at its option, without prior notice to Borrower, to charge all such
amounts to Borrower as a Loan, which amounts thereafter shall accrue interest
as a Loan.  Any interest not paid when due shall be compounded and shall
thereafter accrue interest at the rate then applicable to Loans.

     Section 2.7     Optional Prepayments.  The Borrower may prepay
the Loans, in whole or in part, at any time, without premium or penalty

to carry on their respective businesses as now conducted and to enter into
and perform their obligations under the Loan Documents executed by them and
(in the instance of the Borrower) to issue the Note.  The Borrower and each
of its Subsidiaries are duly qualified and in good standing as a foreign
corporation in each jurisdiction in which the character of the properties
owned, leased or operated by it or the business conducted by it makes such
qualification necessary.

     Section 4.2     Authorization and Validity.  The execution,
delivery and performance by the Borrower and each of the Guarantors of the
Loan Documents executed by them have been duly authorized by all necessary
corporate action by the Borrower or Guarantors, and the Loan Documents
constitute the legal, valid and binding obligations of the Borrower or
Guarantor that executed them, enforceable against the Borrower in accordance
with their respective terms, subject to limitations as to enforceability
which might result from bankruptcy, insolvency, moratorium and other similar
laws affecting creditors' rights generally and subject to limitations on the
availability of equitable remedies.

     Section 4.3     No Conflict; No Default.  The execution,
delivery and performance by the Borrower and each Guarantor of the Loan
Documents executed by them will not (a) violate any provision of any law,
statute, rule or regulation or any order, writ, judgment, injunction, decree,
determination or award of any court, governmental agency or arbitrator
presently in effect having applicability to the Borrower or Guarantors,
(b) violate or contravene any provisions of the Articles (or Certificate) of
Incorporation or by-laws of the Borrower or Guarantors, or (c) result in a
breach of or constitute a default under any indenture, loan or credit
agreement or any other agreement, lease or instrument to which the Borrower
or any Guarantor is a party or by which it or any of its properties may be
bound or result in the creation of any Lien on any asset of the Borrower or
any Subsidiary.  Neither the Borrower nor any Subsidiary is in default under
or in violation of any such law, statute, rule or regulation, order, writ,
judgment, injunction, decree, determination or award or any such indenture,
loan or credit agreement or other agreement, lease or instrument in any case
in which the consequences of such default or violation could cause or have a
Material Adverse Effect.  No Default or Event of Default has occurred and is
continuing.

     Section 4.4     Government Consent.  No order, consent,
approval, license, authorization or validation of, or filing, recording or
registration with, or exemption by, any governmental or public body or
authority is required on the part of the Borrower or any Guarantor to
authorize, or is required in connection with the execution, delivery and
performance of, or the legality, validity, binding effect or enforceability
of, the Loan Documents.

     Section 4.5     Financial Statements and Condition.  The
Borrower's audited consolidated financial statements as at March 31, 2000 and
its company-prepared consolidated financial statements as at December 31,
2000, as heretofore furnished to the Bank, have been prepared in accordance
with GAAP on a consistent basis and fairly present the financial condition of
the Borrower and its Subsidiaries as at such dates and the results of their
operations and changes in financial position for the respective periods then
ended.  As of the dates of such financial statements, neither the Borrower
nor any Subsidiary had any material obligation, contingent liability,
liability for taxes or long-term lease obligation which is not reflected in
such financial statements or in the notes thereto.  Since December 31, 2000,
no Material Adverse Effect has occurred.

     Section 4.6     Litigation and Contingent Liabilities.
Except as described in Exhibit C, there are no actions, suits or proceedings
pending or, to the knowledge of the Borrower, threatened against or affecting
the Borrower or any Subsidiary or any of their properties before any court or
arbitrator, or any governmental department, board, agency or other
instrumentality which, if determined adversely to the Borrower or such
Subsidiary, could constitute a Material Adverse Effect.  Except as described
in Exhibit D, neither the Borrower nor any Subsidiary has any contingent
liabilities which are material to the Borrower and the Subsidiaries as a
consolidated enterprise.

     Section 4.7     Compliance.  The Borrower and its
Subsidiaries are in material compliance with all statutes and governmental
rules and regulations applicable to them.

     Section 4.8     Environmental, Health and Safety Laws.
There does not exist any violation by the Borrower or any Subsidiary of any
applicable federal, state or local law, rule or regulation or order of any
government, governmental department, board, agency or other instrumentality
relating to environmental, pollution, health or safety matters which will or
threatens to impose a material liability on the Borrower or a Subsidiary or
which would require a material expenditure by the Borrower or such Subsidiary
to cure.  Neither the Borrower nor any Subsidiary has received any notice to
the effect that any part of its operations or properties is not in material
compliance with any such law, rule, regulation or order or notice that it or
its property is the subject of any governmental investigation evaluating
whether any remedial action is needed to respond to any release of any toxic
or hazardous waste or substance into the environment, the consequences of
which non-compliance or remedial action could cause or have a Material
Adverse Effect.

     Section 4.9     ERISA.  Each Plan complies with all material
applicable requirements of ERISA and the Code and with all material
applicable rulings and regulations issued under the provisions of ERISA and
the Code setting forth those requirements.  No Reportable Event, other than a
Reportable Event for which the reporting requirements have been waived by
regulations of the PBGC, has occurred and is continuing with respect to any
Plan.  All of the minimum funding standards applicable to such Plans have
been satisfied and there exists no event or condition which would permit the
institution of proceedings to terminate any Plan under Section 4042 of ERISA.
The current value of the Plans' benefits guaranteed under Title IV or ERISA
does not exceed the current value of the Plans' assets allocable to such
benefits.

     Section 4.10    Regulation U.  The Borrower is not engaged
in the business of extending credit for the purpose of purchasing or carrying
margin stock (as defined in Regulation U of the Board of Governors of the
Federal Reserve System) and no part of the proceeds of any Loan will be used
to purchase or carry margin stock or for any other purpose which would
violate any of the margin requirements of the Board of Governors of the
Federal Reserve System.

     Section 4.11    Ownership of Property; Liens.  Each of the
Borrower and the Subsidiaries has good and marketable title to its real
properties and good and sufficient title to its other properties, including
all properties and assets referred to as owned by the Borrower and its
Subsidiaries in the audited financial statement of the Borrower referred to
in Section 4.5 (other than property disposed of since the date of such
financial statement in the ordinary course of business).  None of the
properties, revenues or assets of the Borrower or any of its Subsidiaries is
subject to a Lien, except for (a) Liens disclosed in the financial statements
referred to in Section 4.5, (b) Liens listed on Exhibit E, or (c) Liens
allowed under Section 6.12.

     Section 4.12    Taxes.  Each of the Borrower and the
Subsidiaries has filed all federal, state and local tax returns required to
be filed and has paid or made provision for the payment of all taxes due and
payable pursuant to such returns and pursuant to any assessments made against
it or any of its property and all other taxes, fees and other charges imposed
on it or any of its property by any governmental authority (other than taxes,
fees or charges the amount or validity of which is currently being contested
in good faith by appropriate proceedings and with respect to which reserves
in accordance with GAAP have been provided on the books of the Borrower).  No
tax Liens have been filed and no material claims are being asserted with
respect to any such taxes, fees or charges.  The charges, accruals and
reserves on the books of the Borrower in respect of taxes and other
governmental charges are adequate.

     Section 4.13    Trademarks, Patents.  Each of the Borrower
and the Subsidiaries possesses or has the right to use all of the patents,
trademarks, trade names, service marks and copyrights, and applications
therefor, and all technology, know-how, processes, methods and designs used
in or necessary for the conduct of its business, without known conflict with
the rights of others.

     Section 4.14    Investment Company Act.  Neither the
Borrower nor any Subsidiary is an "investment company" or a company
"controlled" by an investment company within the meaning of the Investment
Company Act of 1940, as amended.

     Section 4.15    Public Utility Holding Company Act.  Neither
the Borrower nor any Subsidiary is a "holding company" or a "subsidiary
company" of a holding company or an "affiliate" of a holding company or of a
subsidiary company of a holding company within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

     Section 4.16    Subsidiaries.  Exhibit F sets forth as of
the date of this Agreement a list of all Subsidiaries and the number and
percentage of the shares of each class of capital stock owned beneficially or
of record by the Borrower or any Subsidiary therein, and the jurisdiction of
incorporation of each Subsidiary.

     Section 4.17    Partnerships and Joint Ventures.   Exhibit G
sets forth as of the date of this Agreement a list of all partnerships or
joint ventures in which the Borrower or any Subsidiary is a partner (limited
or general) or joint venturer.

Section 7.2  	Remedies.

		Section 7.2.1	Generally.	 If (a) any Event of
Default described in Sections 7.1(e), (f) or (g) shall occur with respect to
the Borrower, the Commitment shall automatically terminate and the
outstanding unpaid principal balance of the Note, the accrued interest
thereon and all other obligations of the Borrower to the Bank under the Loan
Documents shall automatically become immediately due and payable; or (b) any
other Event of Default shall occur and be continuing, then the Bank may take
any or all of the following actions:  (i) declare the Commitment terminated,
whereupon the Commitment shall terminate, (ii) declare the outstanding unpaid
principal balance of the Note, the accrued and unpaid interest thereon and
all other obligations of the Borrower to the Bank under the Loan Documents to
be forthwith due and payable, whereupon the Note, all accrued and unpaid
interest thereon and all such obligations shall immediately become due and
payable, in each case without demand or notice of any kind, all of which are
hereby expressly waived, anything in this Agreement or in the Note to the
contrary notwithstanding, (iii) exercise all rights and remedies under any
other instrument, document or agreement between the Borrower and the Bank,
and (iv) enforce all rights and remedies under any applicable law.

		Section 7.2.2 	Letters of Credit.	 In
addition to the remedies described in the Section immediately preceding this
Section, if any Event of Default described in Section 7.1(e), (f) or (g)
shall have occurred, or if any other Event of Default shall have occurred and
the Bank shall have declared that the principal balance of the Note is due
and payable, the Borrower shall pay to the Bank an amount equal to all the
Letter of Credit Obligations.  Such payment shall be in cash, other
immediately available funds or in the form of other collateral acceptable to
the Bank (including, without limitation, letters of credit in form and from
banks acceptable to Bank) and shall be pledged to the Bank (or in the case of
letters of credit, shall be for the benefit of Bank and with such presentment
conditions as are acceptable to Bank).  Such collateral shall be held by the
Bank until the outstanding Letters of Credit are terminated without payment
or are paid and Letter of Credit Obligations with respect thereto are
payable.  In the event the Borrower defaults in the payment of any Letter of
Credit Obligations, the proceeds of the collateral held by Bank shall be
applied to the payment thereof.  The Borrower acknowledges and agrees that
the Bank would not have an adequate remedy at law for failure by the Borrower
to pay immediately to the Bank the amount provided under this Section, and
that the Bank shall have the right to require the Borrower to perform
specifically such undertaking whether or not any of the Letter of Credit
Obligations are due and payable.  Upon the failure of the Borrower to make
any payment required under this Section, the Bank may proceed to use all
remedies available at law or equity to enforce the obligation of the Borrower
to pay or reimburse the Bank.  The balance of any payment due under this
Section shall bear interest payable on demand until paid in full at a per
annum rate equal to the Prime Rate plus 3.00%.


ARTICLE VIII  	MISCELLANEOUS

Section 8.1  	Waiver and Amendment.  No failure on the
part of the Bank or the holder of the Note to exercise and no delay in
exercising any power or right hereunder or under any other Loan Document
shall operate as a waiver thereof; nor shall any single or partial exercise
of any power or right preclude any other or further exercise thereof or the
exercise of any other power or right.  The remedies herein and in any other
instrument, document or agreement delivered or to be delivered to the Bank
hereunder or in connection herewith are cumulative and not exclusive of any
remedies provided by law.  No notice to or demand on the Borrower not
required hereunder or under the Note shall in any event entitle the Borrower
to any other or further notice or demand in similar or other circumstances or
constitute a waiver of the right of the Bank or the holder of the Note to any
other or further action in any circumstances without notice or demand.  No
amendment, modification or waiver of any provision of the Loan Documents or
consent to any departure by the Borrower therefrom shall be effective unless
the same shall be in writing and signed by the Bank, and then such amendment,
modifications, waiver or consent shall be effective only in the specific
instances and for the specific purpose for which given.

Section 8.2 	Expenses and Indemnities.  Whether or not
any Loan is made hereunder, the Borrower agrees to reimburse the Bank upon

employees of the Bank) in connection with the preparation, review, execution,
delivery, amendment, modification, interpretation, collection and enforcement
of the Loan Documents.  The Borrower agrees to pay, and save the Bank
harmless from all liability for, any stamp or other taxes which may be
payable with respect to the execution or delivery of the Loan Documents.  The
Borrower agrees to indemnify and hold the Bank harmless from any loss or
expense which may arise or be created by the acceptance of telephonic or
other instructions for making Loans or disbursing the proceeds thereof,
except that Borrower shall not indemnify Bank for Bank's own gross
negligence.  The obligations of the Borrower under this Section 8.2 shall
survive any termination of this Agreement.

Section 8.3 	Notices.  Except when telephonic notice is
expressly authorized by this Agreement, any notice or other communication to

as such party shall have specified to the other party hereto in writing.  All
periods of notice shall be measured from the date of delivery thereof if
manually delivered, from the date of sending thereof if sent by telegram,
telex or facsimile transmission, from the first Business Day after the date
of sending if sent by overnight courier, or from four days after the date of
mailing if mailed; provided, however, that any notice to the Bank under
Article II hereof shall be deemed to have been given only when received by
the Bank.

Section 8.4 	Successors.  This Agreement shall be binding
upon the Borrower and the Bank and their respective successors and assigns,
and shall inure to the benefit of the Borrower and the Bank and the
successors and assigns of the Bank.  The Borrower shall not assign its rights
or duties hereunder without the written consent of the Bank.

Section 8.5 	Participations and Information.  The Bank
may sell participation interests in any or all of the Loans and in all or any
portion of the Commitment to any Person.  The Bank may furnish any
information concerning the Borrower in the possession of the Bank from time
to time to participants and prospective participants and may furnish
information in response to credit inquiries consistent with general banking
practice.

Section 8.6 	Severability.  Any provision of the
Agreement which is prohibited or unenforceable in any jurisdiction shall, as
to such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

Section 8.7  	Captions.  The captions or headings herein
and any table of contents hereto are for convenience only and in no way
define, limit or describe the scope or intent of any provision of this
Agreement.

Section 8.8  	Entire Agreement.  This Agreement,  the
Note, the Security Agreements executed by Borrower and the Guarantors, the
Guaranties and any of the Letter of Credit Agreements in existence at the
time of the execution of this Agreement, embody the entire agreement and
understanding between the Borrower and the Bank with respect to the subject
matter hereof and thereof.  This Agreement supersedes all prior agreements
and understandings relating to the subject matter hereof.

Section 8.9	Counterparts.  This Agreement may be executed in
any number of counterparts, all of which taken together shall constitute one
and the same instrument, and either of the parties hereto may execute this
Agreement by signing any such counterpart.

Section 8.10	Governing Law.  THE VALIDITY, CONSTRUCTION
AND ENFORCEABILITY OF THIS AGREEMENT AND THE NOTE SHALL BE GOVERNED BY THE
INTERNAL LAWS OF THE STATE OF CALIFORNIA, WITHOUT GIVING EFFECT TO CONFLICT
OF LAWS PRINCIPLES THEREOF, BUT GIVING EFFECT TO FEDERAL LAWS OF THE UNITED
STATES APPLICABLE TO NATIONAL BANKS.

Section 8.11 	Consent to Jurisdiction.  AT THE OPTION OF
THE BANK, THIS AGREEMENT AND THE NOTE MAY BE ENFORCED IN ANY FEDERAL COURT OR
CALIFORNIA STATE COURT SITTING IN LOS ANGELES COUNTY, CALIFORNIA; AND THE
BORROWER CONSENTS TO THE JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVES
ANY ARGUMENT THAT VENUE IN SUCH FORUMS IS NOT CONVENIENT.  IN THE EVENT THE
BORROWER COMMENCES ANY ACTION IN ANOTHER JURISDICTION OR VENUE UNDER ANY TORT
OR CONTRACT THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP
CREATED BY THIS AGREEMENT, THE BANK AT ITS OPTION SHALL BE ENTITLED TO HAVE
THE CASE TRANSFERRED TO ONE OF THE JURISDICTIONS AND VENUES ABOVE-DESCRIBED,
OR IF SUCH TRANSFER CANNOT BE ACCOMPLISHED UNDER APPLICABLE LAW, TO HAVE SUCH
CASE DISMISSED WITHOUT PREJUDICE.

Section 8.12 	Waiver of Jury Trial.  THE BORROWER AND THE
BANK EACH WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO

DELIVERED IN CONNECTION HEREWITH OR (b) ARISING FROM ANY BANKING RELATIONSHIP
EXISTING IN CONNECTION WITH THIS AGREEMENT, AND AGREE THAT ANY SUCH ACTION OR
PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.
