bankruptcy, insolvency, receivership, arrangement, or similar proceedings or
upon an assignment for the benefit of creditors, or upon any other marshaling or
composition of the assets and liabilities of such other Debtor, or otherwise,
(such events, collectively, the "Insolvency Events"): (i) all amounts owing on
account of the Senior Debt shall first be paid, in full, in cash, or payment
provided for in cash or in cash equivalents, before any Subordinated Debt
Payment is made; and (ii) to the extent permitted by applicable law, any
Subordinated Debt Payment to which such Debtor would be entitled except for the
provisions hereof, shall be paid or delivered by the trustee in bankruptcy,
receiver, assignee for the benefit of creditors, or other liquidating lender

          SECTION 4  Payments On Subordinated Debt.

and until such Event of Default is cured or waived, no Debtor shall, without the
prior written consent of Agent:

          (a)  accelerate, make demand, or otherwise make due and payable prior
to the original due date thereof any Subordinated Debt or bring suit or
institute any other actions or proceedings to enforce its rights or interests in
respect of the obligations of any other Debtor owing to such Debtor;

          (b)  exercise any rights under or with respect to guaranties of the
Subordinated Debt, if any;

          (c)  exercise any rights to set-offs and counterclaims in respect of
any indebtedness, liabilities, or obligations of such Debtor to any other Debtor
against any of the Subordinated Debt; or

other than Agent or any Lender in commencing, any bankruptcy, insolvency, or
receivership proceeding against the other Debtor.

          SECTION 6  Payment Over To Agent. In the event that, notwithstanding
the provisions of Sections 3, 4, or 5, any Subordinated Debt Payments shall be
received in contravention of such Sections 3, 4, or 5 by any Debtor before all
Senior Debt is paid, in full, in cash or cash equivalents, such Subordinated
Debt Payments shall be held in trust for the benefit of the Lender Group and
shall be paid over or delivered to Agent for application to the payment, in
full, in cash or cash equivalents of all Senior Debt remaining unpaid to the
extent necessary to give effect to such Sections 3, 4, or 5, after giving effect
to any concurrent payments or distributions to Agent in respect of the Senior
Debt.

          SECTION 7  Authorization To Agent. If, while any Subordinated Debt is
outstanding, any Insolvency Event shall occur and be continuing with respect to
any Debtor or its property: (i) Agent hereby is irrevocably authorized and
empowered (in the name of each other Debtor or otherwise), but shall have no
obligation, to demand, sue for, collect, and receive every payment or
distribution in respect of the Subordinated Debt and give acquittance therefor
and to file claims and proofs of claim and take such other action (including
voting the Subordinated Debt) as it may deem necessary or advisable for the
exercise or enforcement of any of the rights or interests of Agent; and (ii)
each other Debtor shall promptly take such action as Agent reasonably may
request (a) to collect the Subordinated Debt, to the extent permitted by law,
for the account of the Lender Group and to file appropriate claims or proofs of
claim in respect of the Subordinated Debt, (b) to execute and deliver to Agent
such powers of attorney, assignments, and other instruments as it may request to
enable it to enforce any and all claims with respect to the Subordinated Debt,
and (c) to collect and receive any and all Subordinated Debt Payments, to the
extent permitted by law.

          SECTION 8  Certain Agreements Of Each Debtor.

          (a)  No Benefits. Each Debtor understands that there may be various
agreements among Agent, the Lenders, and any other Debtor evidencing and
governing the Senior Debt, and each Debtor acknowledges and agrees that such
agreements are not intended to confer any benefits on such Debtor unless such
Debtor is also a party thereto and that Agent and the Lenders shall have no
obligation to such Debtor or any other Person to exercise any rights, enforce
any remedies, or take any actions which may be available to them under such
agreements unless such Debtor is also a party thereto.

          (b)  No Interference. Each Debtor acknowledges that certain other
Debtors have granted to Agent for the benefit of the Lender Group security
interests in all of such other Debtor's assets, and agrees not to interfere with
or in any manner oppose a disposition of any Collateral by Agent in accordance
with applicable law.

          (c)  Reliance by Agent and Lenders. Each Debtor acknowledges and
agrees that Agent and the Lenders will have relied upon and will continue to
rely upon the subordination provisions provided for herein and the other
provisions hereof in entering into the Loan Documents and making or issuing the
Advances, the Letters of Credit, or other financial accommodations thereunder.

<PAGE>

          (d)  Waivers. Except as provided under the Loan Agreement, each Debtor
hereby waives any and all notice of the incurrence of the Senior Debt or any
part thereof and any right to require marshaling of assets.

          (e)  Obligations of Each Debtor Not Affected. Each Debtor hereby
agrees that at any time and from time to time, without notice to or the consent
of such Debtor, without incurring responsibility to such Debtor, and without
impairing or releasing the subordination provided for herein or otherwise
impairing the rights of Agent hereunder: (i) the time for any other Debtor's
performance of or compliance with any of its agreements contained in the Loan
Documents may be extended or such performance or compliance may be waived by
Agent or the Lenders; (ii) the agreements of any other Debtor with respect to
the Loan Documents may from time to time be modified by such other Debtor,
Agent, and the Lenders for the purpose of adding any requirements thereto or
changing in any manner the rights and obligations of such other Debtor, Agent,
or the Lenders thereunder; (iii) the manner, place, or terms for payment by any
other Debtor of Senior Debt or any portion thereof may be altered or the terms
for payment extended, or the Senior Debt of any other Debtor may be renewed in
whole or in part; (iv) the maturity of the Senior Debt of any other Debtor may
be accelerated in accordance with the terms of any present or future agreement
by any other Debtor, Agent, and the Lenders; (v) any Collateral may be sold,
exchanged, released, or substituted and any Lien in favor of Agent may be
terminated, subordinated, or fail to be perfected or become unperfected; (vi)
any Person liable in any manner for Senior Debt may be discharged, released, or
substituted; and (vii) all other rights against the other Debtors, any other
Person, or with respect to any Collateral may be exercised (or Agent may waive
or refrain from exercising such rights).

          (f)  Rights of Agent Not to Be Impaired. No right of Agent or the
Lenders to enforce the subordination provided for herein or to exercise its
other rights hereunder shall at any time in any way be prejudiced or impaired by
any act or failure to act by any Debtor, Agent, or the Lenders hereunder or
under or in connection with the other Loan Documents or by any noncompliance by
the other Debtors with the terms and provisions and covenants herein or in any
other Loan Document, regardless of any knowledge thereof Agent or the Lenders
may have or otherwise be charged with.

          (g)  Financial Condition of the Debtors. Except as provided under the
Loan Agreement or by applicable law, no Debtor shall have any right to require
Agent to obtain or disclose any information with respect to: (i) the financial
condition or character of any other Debtor or the ability of any other Debtor to
pay and perform Senior Debt; (ii) the Senior Debt; (iii) the Collateral or other
security for any or all of the Senior Debt; (iv) the existence or nonexistence
of any guarantees of, or any other subordination agreements with respect to, all
or any part of the Senior Debt; (v) any action or inaction on the part of Agent
or any other Person; or (vi) any other matter, fact, or occurrence whatsoever.

          (h)  Acquisition of Liens or Guaranties. No Debtor shall, without the
prior consent of Agent, acquire any right or interest in or to any Collateral
not owned by such Debtor or accept any guaranties for the Subordinated Debt.

          SECTION 9  Subrogation.

                                        5

<PAGE>

          (a)  Subrogation. Until the payment and performance in full of all
Senior Debt, each Debtor agrees to postpone, and shall not directly or
indirectly exercise, any rights that it may acquire by way of subrogation under
this Agreement, by any payment or distribution to Agent hereunder or otherwise.
Upon the payment and performance in full of all Senior Debt, each Debtor shall
be subrogated to the rights of Agent and Lenders to receive payments or
distributions applicable to the Senior Debt until the Subordinated Debt shall be
paid in full. For the purposes of the foregoing subrogation, no payments or
distributions to Agent of any cash, property, or securities to which any Debtor
would be entitled except for the provisions of Section 3, 4, or 5 shall, as
among such Debtor, its creditors (other than Agent and the Lenders), and the
other Debtors, be deemed to be a payment by the other Debtors to or on account
of the Senior Debt.

          (b)  Payments Over to the Debtors. If any payment or distribution to
which any Debtor would otherwise have been entitled but for the provisions of
Section 3, 4, or 5 shall have been applied pursuant to the provisions of Section
3, 4, or 5 to the payment of all amounts payable under the Senior Debt, such
Debtor shall be entitled to receive from Agent or the Lenders any payments or
distributions received by Agent or the Lenders in excess of the amount
sufficient to pay in full in cash all amounts payable under or in respect of the
Senior Debt. If any such excess payment is made to Agent or the Lenders, Agent
or the Lenders shall promptly remit such excess to such Debtor and until so
remitted shall hold such excess payment for the benefit of such Debtor.

          SECTION 10 Continuing Agreement; Reinstatement.

          (a)  Continuing Agreement. This Agreement is a continuing agreement of
subordination and shall continue in effect and be binding upon each Debtor until
payment and performance in full in cash of the Senior Debt. The subordinations,
agreements, and priorities set forth herein shall remain in full force and
effect regardless of whether any party hereto in the future seeks to rescind,
amend, terminate, or reform, by litigation or otherwise, its respective
agreements with the other Debtor.

          (b)  Reinstatement. This Agreement shall continue to be effective or
shall be reinstated, as the case may be, if, for any reason, any payment of the
Senior Debt by or on behalf of any other Debtor shall be rescinded or must
otherwise be restored by Agent or the Lenders, whether as a result of an
Insolvency Event or otherwise.

          SECTION 11 Transfer Of Subordinated Debt. No Debtor may assign or
transfer its rights and obligations in respect of the Subordinated Debt without
the prior written consent of Agent, and any such transferee or assignee, as a
condition to acquiring an interest in the Subordinated Debt shall agree to be
bound hereby, in form satisfactory to Agent.

          SECTION 12 Obligations Of The Debtors Not Affected. The provisions of
this Agreement are intended solely for the purpose of defining the relative
rights of each Debtor against the other Debtors, on the one hand, and of Agent
and the Lenders against the Debtors, on the other hand. Nothing contained in
this Agreement shall (i) impair, as between each Debtor and the other Debtors,
the obligation of the other Debtors to pay their respective obligations with
respect to the Subordinated Debt as and when the same shall become due and
payable, or (ii)

                                        6

<PAGE>

otherwise affect the relative rights of each Debtor against the other Debtors,
on the one hand, and of the creditors (other than Agent or the Lenders) of the
other Debtors against the other Debtors, on the other hand.

          SECTION 13 Endorsement Of Debtor Documents; Further Assurances And
Additional Acts.

          (a)  Endorsement of Debtor Documents. At the request of Agent, all
documents and instruments evidencing any of the Subordinated Debt, if any, shall
be endorsed with a legend noting that such documents and instruments are subject
to this Agreement, and each Debtor shall promptly deliver to Agent evidence of
the same.

          (b)  Further Assurances and Additional Acts. Each Debtor shall
execute, acknowledge, deliver, file, notarize, and register at its own expense
all such further agreements, instruments, certificates, financing statements,
documents, and assurances, and perform such acts as Agent reasonably shall deem
necessary or appropriate to effectuate the purposes of this Agreement, and
promptly provide Agent with evidence of the foregoing reasonably satisfactory in
form and substance to Agent.

          SECTION 14 Notices. All notices and other communications hereunder to
Agent shall be in writing and shall be mailed, sent or delivered in accordance
with the Loan Agreement and all notices and other communications hereunder to a
Debtor shall be in writing and shall be mailed, sent or delivered in care of
Borrower in accordance with the Loan Agreement.

          SECTION 15 No Waiver; Cumulative Remedies. No failure on the part of
Agent or the Lenders to exercise, and no delay in exercising, any right, remedy,
power, or privilege hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right, remedy, power, or privilege
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power, or privilege. The rights and remedies under this Agreement
are cumulative and not exclusive of any rights, remedies, powers, and privileges
that may otherwise be available to Agent and the Lenders.

          SECTION 16 Costs And Expenses. Each of the Debtors, jointly and
severally, agrees to pay to Agent on demand the (a) reasonable out-of-pocket
costs and expenses of Agent, and the reasonable fees and disbursements of
counsel to Agent, in connection with the negotiation, preparation, execution,
delivery, and administration of this Agreement, and any amendments,
modifications, or waivers of the terms thereof; and (b) all reasonable
out-of-pocket costs and expenses of Agent, and the reasonable fees and
disbursements of counsel, in connection with the enforcement or attempted
enforcement of, and preservation of rights or interests under, this Agreement,
including any losses, reasonable out-of-pocket costs and expenses sustained by
Agent as a result of any failure by any Debtor to perform or observe its
obligations contained in this Agreement.

          SECTION 17 Survival. All covenants, agreements, representations and
warranties made in this Agreement shall, except to the extent otherwise provided
herein, survive the execution and delivery of this Agreement, and shall continue
in full force and effect so long

                                        7

<PAGE>

as any Senior Debt remains unpaid. Without limiting the generality of the
foregoing, the obligations of each Debtor under Section 16 shall survive the
satisfaction of the Senior Debt.

          SECTION 18 Benefits Of Agreement. This Agreement is entered into for
the sole protection and benefit of the parties hereto and their successors and
assigns, and no other person shall be a direct or indirect beneficiary of, or
shall have any direct or indirect cause of action or claim in connection with,
this Agreement.

          SECTION 19 Binding Effect. This Agreement shall be binding upon, inure
to the benefit of and be enforceable by each Debtor, Agent, and the Lenders and
their respective successors and permitted assigns.

          SECTION 20 Governing Law. This Agreement shall be governed by, and
construed and enforced in accordance with, the law of the State of California.

          SECTION 21 Submission To Jurisdiction; Waiver of Jury Trial. Each
Debtor hereby (i) submits to the exclusive jurisdiction of the courts of the
County of Los Angeles, State of California and the federal courts of the United
States sitting in the County of Los Angeles, State of California, for the
purpose of any action or proceeding arising out of or relating to this
Agreement, (ii) agrees that all claims in respect of any such action or
proceeding may be heard and determined in such courts, or at the sole option of
Agent, in any other court which has subject matter jurisdiction over the matter
in controversy, (iii) irrevocably waives (to the extent permitted by applicable
law) any objection which it now or hereafter may have to the laying of venue of
any such action or proceeding brought in any of the foregoing courts, and any
objection on the ground that any such action or proceeding in any such court has
been brought in an inconvenient forum, (iv) agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner permitted by law,
and (v) EACH DEBTOR HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF
THE TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH DEBTOR
REPRESENTS THAT EACH SUCH PARTY HAS REVIEWED THIS WAIVER AND EACH SUCH PARTY
KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION
WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF THIS AGREEMENT MAY BE
FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

          SECTION 22 Entire Agreement; Amendments And Waivers.

          (a)  Entire Agreement. This Agreement constitutes the entire agreement
of each of the Debtors and Agent with respect to the matters set forth herein
and supersedes any prior agreements, commitments, drafts, communications,
discussions, and understandings, oral or written, with respect thereto. None of
the terms or conditions of this Agreement imposes on the Debtors any obligation
or liability under any Loan Document (other than this Agreement). The foregoing
notwithstanding, the terms and conditions of this Agreement shall not in any way

                                        8

<PAGE>

limit or affect the obligations or liabilities of any Debtor under the Loan
Documents to which such Debtor is a party.

          (b)  Amendments and Waivers. No amendment to any provision of this
Agreement shall in any event be effective unless the same shall be in writing
and signed by each of the Debtors and Agent; and no waiver of any provision of
this Agreement, or consent to any departure by any Debtor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent.
Any such amendment, waiver, or consent shall be effective only in the specific
instance and for the specific purpose for which given.

          SECTION 23 Conflicts. In case of any conflict or inconsistency between
any terms of this Agreement, on the one hand, and any documents or instruments
in respect of the Subordinated Debt, on the other hand, then the terms of this
Agreement shall control.

          SECTION 24 Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
all applicable laws and regulations. If, however, any provision of this
Agreement shall be prohibited by or invalid under any such law or regulation in
any jurisdiction, it shall, as to such jurisdiction, be deemed modified to
conform to the minimum requirements of such law or regulation, or, if for any
reason it is not deemed so modified, it shall be ineffective and invalid only to
the extent of such prohibition or invalidity without affecting the remaining
provisions of this Agreement or the validity or effectiveness of such provision
in any other jurisdiction.

          SECTION 25 Interpretation. This Agreement is the result of
negotiations between, and has been reviewed by the respective counsel to, the
Debtors and Agent and is the product of all parties hereto. Accordingly, this
Agreement shall not be construed against Agent merely because of Agent's
involvement in the preparation hereof.

          SECTION 26 Counterparts; Telefacsimile Execution. This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute but one and the same
agreement. Delivery of an executed counterpart of this Agreement by
telefacsimile shall be equally effective as delivery of an original executed
counterpart of this Agreement. Any party delivering an executed counterpart of
this Agreement by telefacsimile also shall deliver an original executed
counterpart of this Agreement but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Agreement.

          SECTION 27 Termination Of Agreement. Upon indefeasible payment and
performance in full of the Senior Debt, this Agreement shall terminate and Agent
shall promptly execute and deliver to each Debtor such documents and instruments
as shall be reasonably necessary to evidence such termination; provided,
however, that the obligations of each Debtor under Section 16 shall survive such
termination.

                            [Signature page follows.]
