the case may be, in trust under this Agreement and the Collateral Documents for
the equal and ratable benefit of the Secured Parties (and the Persons for whom
the Secured Parties act as trustee, agent or fiduciary, as applicable), without
preference, priority or distinction of any thereof over any other by reason of
difference in time of issuance, sale or otherwise, as provided herein.  Each
Secured Party, by executing and delivering this Agreement, and each Person for
whom such Secured Party acts as trustee, agent or fiduciary, as applicable, by
acceptance of the benefits of this Agreement and the Collateral Documents, (i)
consents to the appointment of the Collateral Agent as agent hereunder and
grants to the Collateral Agent all rights and powers necessary for the
Collateral Agent to perform its obligations hereunder, (ii) confirms that the

remedies or give any such consents or approvals relating to any Collateral or
the Collateral Documents or itself make any claim under the Title Policies.  If
the Companies request that the Collateral Agent or the Secured Parties (or any
Person for whom such Secured Party acts as a trustee, agent or fiduciary, as
applicable) elect to defer for 3 years the effective date of regulatory
amendments effective July 1, 1997 with respect to Washington State Business and
Occupancy Tax, the Collateral Agent or such Secured Party is hereby authorized
to do so, and by accepting the benefits of this Agreement, each Person for whom
a Secured Party acts as trustee, agent or fiduciary, as applicable, hereby
consents to such action.

                 2.2      Remedies.  (a)  Upon the occurrence and during the
continuance of an Event of Default under the Indenture, the Note Majority
Holders shall have the right at any time, and, upon the occurrence and during
the continuance of an Event of Default under the Term Loan Agreement, the Term
Loan Note Majority Holders shall have the right at any time, to direct in one

Agent and the Secured Parties that any right or remedy available to the
Collateral Agent and the Trustee or the Term Loan Agent, as the case may be,
with respect to the Collateral  be exercised by the Collateral Agent on behalf
of both Secured Parties (subject to Section 6.3 hereof), which Enforcement
Notice shall be effective 10 days from the date of delivery thereof, provided,
however, that the Note Majority Holders or the Term Loan Note Majority Holders,
as the case may be, taking such action must hold an aggregate principal amount
of Notes or Term Loan Notes, as the case may be, representing at least 15% of
the Total Amount of Secured Obligations.  Each Enforcement Notice shall state
that an Event of Default either under the Indenture or the Term Loan Agreement
exists and generally describe the nature of and any relevant facts relating to
such Event of Default.  Following receipt of any Enforcement Notice, the
Collateral Agent shall, subject to the provisions hereof relating to
indemnification of the Collateral Agent by the Companies, take the actions
directed therein and any other actions which it deems proper and which are not
inconsistent with such direction, provided, however, the Collateral Agent is
not obligated to take any actions outside the Enforcement Notice.

                                                                              10




                 (b)  Upon the effective date of an Enforcement Notice from the
Note Majority Holders or the Term Loan Note Majority Holders, as the case may
be, the Collateral Agent shall notify PCAC and/or PAI, as applicable, in
writing that the Collateral Agent has received such Enforcement Notice,
enclosing a copy of such Enforcement Notice.  An Enforcement Notice shall be
deemed to be in effect hereunder only if such notice shall have been given and
not rescinded, annulled or withdrawn in writing by the Note Majority Holders or
the Term Loan Note Majority Holders, as applicable, by whom such notice was
given.

                 (c)      Whether or not the Collateral Agent has been directed
to exercise any right or remedy with respect to the Collateral pursuant to the
provisions of this Section 2.2, the Bank Lenders shall have the right, subject
to all relevant provisions of the Bank Credit Agreement, to pursue remedies
with respect to Obligor Collateral in accordance with the provisions of the
Bank Credit Agreement, all related agreements and this Agreement.  In the event
that the Collateral Agent has been so instructed to pursue remedies with
respect to the Collateral, the Collateral Agent shall take such steps as it
deems reasonable and appropriate to avoid interfering with the Agent Bank's
exercise of rights and remedies with respect to Obligor Collateral.

                 (d)  In the event that the Agent Bank shall attempt to
exercise any of its remedies with respect to Obligor Collateral, the Collateral
Agent (i) shall not hinder, delay or otherwise prevent the Agent Bank from
taking any and all action to the extent permitted by law which the Agent Bank
deems necessary to enforce its security interest in the Obligor Collateral and
realize thereon and (ii) to the extent that the Collateral Agent is in
possession of the Mortgaged Property, shall permit the Agent Bank to access and
occupy the Mortgaged Property and to use the Equipment, in each case without
rent, for a period not to exceed 90 days from the date Agent Bank receives
written notice from the Collateral Agent that it has acquired possession of the
Mortgaged Property, or such shorter period as is necessary for the Agent Bank
to complete Obligor Collateral consisting of work-in-process, to store Obligor
Collateral constituting inventory and to otherwise remove such Obligor
Collateral and complete its exercise of remedies in respect thereof.  Agent
Bank shall indemnify the Collateral Agent for all damage to the Mortgaged
   11
                                                                              11



Property or the Equipment (ordinary wear and tear excepted) proximately caused
by the negligence or willful misconduct of the Agent Bank or its agents or
employees.  The Collateral Agent further agrees that it will not enforce any
statutory, possessory or other liens (including, without limitation, rights of
levy) with respect to the Obligor Collateral without the prior written consent
of the Agent Bank.

                 (e)  Without limiting the provisions of the preceding
paragraphs (c) and (d), the Collateral Agent shall not seek to enforce any
rights under or with respect to the agreements (the "Tacoma Sales Agreements")
listed as items 3 and 4 on Annex 2 to the Security Agreement (as in effect of
the date hereof) or any related Collateral (as defined in the Security
Agreement) and shall not retain any proceeds thereof until the Agent Bank has
collected all Accounts Receivable (as defined in the Bank Credit Agreement as
in effect on the date hereof in existence under the Tacoma Sales Agreements and
completed and sold all Inventory (as defined in the Bank Credit Agreement as in
effect on the date hereof) pursuant to the terms of the Tacoma Sales Agreements
to the purchasers thereunder, to the extent that such Accounts Receivable and
Inventory were included in the calculation of the Borrowing Base (as defined on
the Bank Credit Agreement as in effect on the date hereof) prepared by PAAC for
the purpose of calculating loans made to PAAC under the Bank Credit Agreement
and delivered to the Agent Bank most recently prior to the acceleration of any
of the Secured Obligations (and in connection therewith the Agent Bank may
enforce Contract Rights under the Tacoma Sales Agreements), provided that (i)
the Agent Bank shall seek to collect such Accounts Receivable, sell such
Inventory and otherwise enforce Contract Rights in respect of the Tacoma Sales
Agreements reasonably promptly and otherwise in a commercially reasonable
manner that will not unreasonably prejudice the remaining rights of the
Collateral Agent and the Secured Parties with respect to such agreements; and
(ii) upon payment in full of such Accounts Receivable and the sale of such
Inventory pursuant to the Tacoma Sales Agreements, (x) the Agent Bank shall
have no further lien on or other interest in the Tacoma Sales Agreements or in
any Accounts Receivable or Contract Rights (as defined on the Bank Credit
Agreement as in effect on the date hereof) in respect thereof and (y) the
Tacoma Sales Agreements and all
   12
                                                                              12



Accounts Receivable and Contract Rights in respect thereof shall be deemed
deleted from the definition of Obligor Collateral.

                 2.3      Determinations Relating to Collateral.  In the event
(i) the Collateral Agent shall receive any written request from any Obligor
under any Collateral Document for consent or approval with respect to any
matter or thing relating to any Collateral or such Obligor's obligations with
respect thereto or (ii) there shall be due to or from the Collateral Agent
under the provisions of any Collateral Document any material performance or the
delivery of any material instrument or (iii) the Collateral Agent shall have
actual knowledge of any nonperformance by any Obligor of any covenant or any
breach of any representation or warranty of any Obligor set forth in any
Collateral Document, then, in each such event, the Collateral Agent shall,
within five Business Days (as defined in the Indenture, as in effect on the
date hereof), advise the Secured Parties in writing of the matter or thing as
to which consent has been requested or the performance or instrument required
to be delivered or the nonperformance or breach of which the Collateral Agent
has become aware.  The Majority Holders shall have the exclusive authority to
direct the Collateral Agent's response to any of the circumstances contemplated
in clauses (i), (ii) and (iii) above, provided that the Majority Holders
include the Term Loan Note Majority Holders.

                 2.4      Right to Make Advances.  If an advance of funds shall
at any time be required for the preservation or maintenance of any Collateral,
then, upon three Business Days' notice to the applicable Obligor, the
Collateral Agent or either Secured Party shall be entitled (but shall not be
obligated) to make such advance (it being understood that the Trustee shall not
be obligated to make any such advance other than in accordance with the terms
of the Indenture and that the Term Loan Agent shall not be obligated to make
any such advance other than in accordance with the terms of the Term Loan
Agreement).  Each such advance shall be reimbursed, with interest from the date
such advance was made (at the rate initially borne by the Notes or the Term
Loan Notes, as applicable), by the applicable Obligor, upon demand by the
Collateral Agent or such Secured Party, as the case may be, and if the
applicable Obligor fails to comply with any such demand, out of the proceeds of

Secured Party shall remit such funds promptly to the Collateral Agent for
distribution to the Collateral Agent or such other Secured Party, as the case

required pursuant to and in accordance with the provisions of the Indenture or
the Term Loan Agreement, respectively, advise in writing the Persons for whom
it acts as trustee, agent or fiduciary of the matters or thing to which such
vote or consent pertain and afford such Persons an opportunity to indicate

prescribed time period) a response to the matters or things set forth in such
writing.  The results of such voting or consent solicitation shall be promptly
reported in writing to the Collateral Agent and shall be certified as correct
to the best knowledge of such Secured Party.  Any determination as to whether
the requisite vote or consent has been obtained shall be made by the Collateral
Agent on the basis of such written information, which information may be

not be liable for errors in such determinations unless the Collateral Agent
shall have been grossly negligent or shall have acted in bad faith in
connection therewith.

the Collateral Agent, and PCAC requests in writing that the Collateral Agent

herefrom shall be entitled to rely upon any release executed by the Collateral
Agent hereunder as sufficient for the purposes hereof.

         designate a purchaser, or under the order or orders directing such
         sale, as the case may be;

                 (iv)  in the event that the award for such property or the
         proceeds of such sale, or a specified portion thereof, shall be
         certified to have been deposited with the trustee, mortgagee or other
         holder of a Lien which is permitted by the Collateral Documents to be
         prior to the Lien of the Collateral Documents, that the property to be
         released, or a specified portion thereof, is or immediately before
         such taking or purchase was subject to such prior Lien permitted by
         the Collateral Documents, and that such deposit is required by such

hereof, the Majority Holders (provided that such Majority Holders include the
Term Loan Majority Holders) shall have the right to direct the Collateral
Agent, and if so directed, the Collateral Agent shall have the power, to
institute and to maintain such suits and proceedings as such Majority Holders
may deem expedient to prevent any impairment of the Collateral by any acts
which may be unlawful or in violation of any of the Collateral Documents, and
such suits and proceedings as such Majority Holders may deem expedient to
preserve or protect their interests in the Collateral (including power to
institute and maintain suits or proceedings to restrain the enforcement of or
compliance with any legislative or other governmental enactment, rule or order
that may be unconstitutional or otherwise invalid if the enforcement of, or
compliance with, such enactment, rule or order would impair the Liens of the
Collateral Agent in the Collateral or be prejudicial to the interests of the
Secured Parties).

                 3.6  Purchaser Protected.  In no event shall any purchaser in
good faith of any property purported to be released hereunder be bound to
ascertain the authority of the Collateral Agent to execute the release or to
inquire as to the satisfaction of any conditions required by the provisions
hereof for the exercise of such authority or to see to the application of any
consideration given by such purchaser or other transferee; nor shall any
purchaser or other transferee of any property or rights permitted by this
Article 3 to be sold be under obligation to ascertain or inquire into the
authority of PAI or PCAC to make any such sale or other transfer.

                 3.7  Powers Exercisable by Receiver or Trustee.  In case the
Collateral shall be in the possession of a receiver or trustee, lawfully
appointed, the powers conferred in this Article 3 upon PAI and PCAC with
respect to the release, sale or other disposition of such property may be
exercised by such receiver or trustee, and an instrument signed by such
receiver or trustee shall be deemed the equivalent of any similar instrument
   25
                                                                              25



of PAI or PCAC, as the case may be, or of any officer or officers thereof
required by the provisions of this Article 3.

                 3.8  Determinations Relating to Collateral.  In the event (i)
the Collateral Agent shall receive any written request from PCAC or PAI under
any Collateral Document for consent or approval with respect to any matter or
thing relating to any Collateral or the obligations of any Obligor with respect
thereto or (ii) there shall be due to or from the Collateral Agent under the
provisions of any Collateral Document any performance or the delivery of any
instrument or (iii) the Collateral Agent shall have actual knowledge of any
nonperformance by any Obligor of any covenant or any breach of any
representation or warranty of such Obligor set forth in any Collateral
Document, then, in each such event, the Collateral Agent shall be entitled to
hire experts, consultants, agents and attorneys to advise the Collateral Agent
on the manner in which the Collateral Agent should respond to such request or
render any requested performance or response to such nonperformance or breach.
The Collateral Agent shall be fully protected in the taking of any action
recommended or approved by any such expert, consultant, agent or attorney or
agreed to by the Majority Holders and the Term Loan Note Majority Holders.

                 3.9  Form and Sufficiency of Release.  In the event that PAI
or PCAC has sold, exchanged, or otherwise disposed of or proposes to sell,
exchange or otherwise dispose of any portion of the Collateral which under the
provisions of this Article 3 may be sold, exchanged or otherwise disposed of by
PAI or PCAC, and the applicable Obligor requests the Collateral Agent to
furnish a written disclaimer, release or quitclaim of any interest in such
property under any of the Collateral Documents, the Collateral Agent shall
execute such an instrument promptly after satisfaction of the conditions set
forth herein for delivery of such instrument.  Notwithstanding the preceding
sentence, all purchasers and grantees of any property or rights purporting to
be released herefrom shall be entitled to rely upon any release executed by the
Collateral Agent hereunder as sufficient for the purposes of this Indenture and
as constituting a good and valid release of the property therein described from
the Lien of this Indenture and the Collateral Documents.
   26
                                                                              26




                 3.10  Possession and Use of Collateral.  Subject to and in
accordance with the provisions of this Agreement and the other Collateral

Agreement or Event of Default under either the Indenture or the Term Loan
Agreement shall have occurred and be continuing, the Obligors shall have the
right to remain in possession and retain exclusive control of the Collateral
(other than Trust Moneys, as defined in Section 4.1 hereof, securities and
other personal property held by, or required to be deposited or pledged with,
the Collateral Agent hereunder or under the other Collateral Documents), to
operate, manage, develop, use and enjoy the Collateral (other than Trust

proceeds and other income thereof (other than Trust Moneys, securities and
other personal property held by, or required to be deposited or pledged with,
the Collateral Agent hereunder or under the other Collateral Documents).

                 3.11  Additional Indebtedness and Additional Collateral.  In
the event that PAAC or the Subsidiary Guarantors incur additional Indebtedness
(the "Additional Obligation") as permitted under Section 1008 of the Indenture
and Section 7.2.2 of the Term Loan Agreement, and provided that (a) the assets
or property acquired or constructed with the Additional Obligation (the
"Additional Collateral") are pledged and a first priority mortgage or security
interest (as applicable) therein is granted to the Collateral Agent to become a
part of the Collateral securing the Secured Obligations on a pari passu basis,
and the other conditions set forth in Section 1012(j) of the Indenture and
clause (j) of Section 7.2.2 of the Term Loan Agreement are satisfied, and (b)
the Collateral Agent shall have received an endorsement to its Title Policies
insuring the continuing priority of the Mortgages as set forth in the Title
Policies, then this Agreement shall be amended to add as Secured Parties the
holders of the Additional Obligation or any trustee or other representative
thereof (the "Additional Secured Party") and to permit the Additional Secured
Party to exercise rights and remedies in accordance therewith, and the other
Collateral
   27
                                                                              27



Documents will be amended to add the Additional Obligation to the definition of
Secured Obligations therein.

soon as practicable after receipt as follows:

                 FIRST:  To the Collateral Agent in an amount equal to the
Collateral Agent's Fees which are unpaid as of the applicable Distribution Date
and to any Secured Party which has theretofore advanced or paid any such
Collateral Agent's Fees in an amount equal to the amount thereof so advanced or
paid by such Secured Party and to reimburse to the Collateral Agent and any

defined in the Indenture as in effect on the date hereof) or to the permanent
repayment or prepayment of any Senior Indebtedness (as defined in the Indenture
as in effect on the date hereof) then outstanding; and (iii) any such Trust

used to make an Asset Sale Offer pursuant to Section 1009 of the Indenture.
   29
                                                                              29

in this Article 4 conferred upon the Obligors with respect to the withdrawal or
application of Trust Moneys may be exercised by such receiver or trustee, in
which case a certificate signed by such receiver or trustee shall be deemed the
equivalent of any Officers' Certificate required by this Article.  If the
Collateral Agent shall be in possession of any of the Collateral hereunder or

Collateral Agent in its discretion, provided, however, that the Collateral

Default either under the Indenture or the Term Loan Agreement or an Event of
Default either under the Indenture or the Term Loan Agreement has occurred and

soon as practicable, apply the Trust Moneys and any Insurance Proceeds, Net
Awards, Rents (as defined in the Mortgages) or other amounts or proceeds from
the sale or other disposition of or realization upon any Collateral (including
proceeds of any claim under the Title Policies) as follows: first to the

the product of (x) the total amount available for distribution on such
Distribution Date under this Section 6.1 (such amount, "Total Net Proceeds")
and (y) the Trustee's Pro Rata Share as of such Distribution Date and (ii) to
the Term Loan Agent in an amount equal to the product of (x) Total Net Proceeds
and (y) the Term Loan Agent's Pro Rata Share as of such Distribution Date.

                 (b)  Upon payment in full of all Collateral Agent's Fees and
all Secured Obligations, any balance shall be paid by the Collateral Agent to
PAAC or the successors or assigns of PAAC, as their interests may appear, or to
such Person who may be lawfully entitled to receive the same.

                 6.2      Payment Provisions.  For the purposes of Section 6.1,

recognized or allowed by any bankruptcy proceeding, be treated as due and owing
on the Secured Obligations.

                 6.3  Foreclosure of Less than the Total Secured Obligations.
In the event that the Collateral Agent is not authorized pursuant to Section
2.2(b) to accelerate the Secured Obligations as a whole in connection with an
exercise of remedies with respect to the Collateral, and the Trustee or the
Term Loan Agent, as the case may be, does not otherwise accelerate its
respective obligation prior to the exercise of remedies by the Collateral Agent
under the applicable Mortgage, the proceeds of such exercise of remedies shall
be applied, notwithstanding Section 6.1, solely to the obligation being
accelerated.

legality or sufficiency of the Collateral Documents or this Agreement or of the
Secured Obligations, and the Collateral Agent shall incur no liability or
responsibility in respect of any such matters.  The Collateral Agent shall not
be responsible for insuring the Trust Estate or for the payment of taxes,
charges, assessments or Liens upon the Trust Estate, except that, subject to
the provisions of Section 8.4(c), in the event the Collateral Agent enters into
possession of a part or all of the Collateral, the Collateral Agent shall use
reasonable efforts to preserve the part in its possession.

                 (b)      The Collateral Agent shall not be required to
ascertain or inquire as to the performance by any Obligor of any of the
covenants or agreements contained herein, in any Collateral Document or in any
Debt Instrument or other document
   46
                                                                              46



evidencing or securing the Secured Obligations.  Whenever it is necessary, or
in the opinion of the Collateral Agent advisable, for the Collateral Agent to
ascertain the amount of Secured Obligations then held by a Secured Party (or
any Person for whom a Secured Part acts as trustee, agent or fiduciary), the
Collateral Agent may rely on a certificate as to such amount from any trustee,
agent or fiduciary constituting or representing such Secured Party and if any
such Secured Party shall not provide such information to the Collateral Agent,
such Secured Party shall not be entitled to receive payments hereunder (in
which case the amounts otherwise payable to such Secured Party shall be held in
trust for such Secured Party in the Collateral Account) until such Secured
Party has provided such information to the Collateral Agent.

                 (c)      The Collateral Agent shall not be personally liable
for any action taken or omitted to be taken by it in accordance with this
Agreement or any Collateral Document or any Debt Instrument or other document
evidencing or securing the Secured Obligations except for its own gross
negligence or willful misconduct.

                 8.3      Delegation of Duties.  The Collateral Agent may
execute any of the trusts or powers hereof and perform any duty hereunder
either directly or by or through agents or attorneys-in-fact.  The Collateral
Agent shall be entitled to advice of counsel concerning all matters pertaining
to such trusts, powers and duties.  The Collateral Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys-in-fact
selected by it without gross negligence of willful misconduct in the employment
of such agents or attorneys-in-fact.

                 8.4      Reliance by the Collateral Agent.  (a) The Collateral
Agent may consult with counsel, and any opinion of such counsel shall be full
and complete authorization and protection in respect of any action taken or
suffered by it hereunder in accordance therewith.  The Collateral Agent shall
have the right at any time to seek instructions concerning the administration
of the Trust Estate from any court of competent jurisdiction.
   47
                                                                              47




                 (b)      The Collateral Agent may rely, and shall be fully
protected in acting, upon any resolution, statement, certificate, instrument,
opinion, direction, instruction, report, notice, request, consent, order, bond
or other paper or document which it has no reason to believe to be other than
genuine and to have been signed or presented by the proper party or parties or,
in the case of cables, telecopies and telexes, to have been sent by the proper
party or parties.  In the absence of its gross negligence or willful
misconduct, the Collateral Agent may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Collateral Agent and conforming to
the requirements of this Agreement or any Collateral Document.

                 (c)      The Collateral Agent shall not be under any
obligation to exercise any of the rights or powers vested in the Collateral
Agent by this Agreement unless the Collateral Agent shall have been provided
adequate security and indemnity against the costs, expenses and liabilities
that may be incurred by it in compliance with such request or direction,
including, without limitation, such reasonable advances as may be requested by
the Collateral Agent.  Nothing in this Agreement shall obligate any Secured
Party or any Person for whom a Secured Party acts as trustee, agent or
fiduciary, as applicable to provide any such security or indemnity or to make
any such advance unless such Secured Party or Person agrees to do so, in its
sole discretion.

                 8.5      Resignation or Removal of the Collateral Agent.  (a)
The Collateral Agent may at any time, (i) by giving 60 days' prior written
notice to the Secured Parties and the Companies, resign and be discharged of
the responsibilities hereby created, such resignation to become effective upon
the appointment of a successor collateral agent or collateral agents by the
Majority Holders and the acceptance of such appointment by such successor
collateral agent or collateral agents or (ii) be removed from its capacity as
the Collateral Agent with or without cause by the Majority Holders.  If no
successor collateral agent or collateral agents shall be appointed and approved
within 60 days from the date of the giving of the aforesaid notice of
resignation or within 60 days from the date of such removal, the Collateral
Agent (notwithstanding the termination of all of its other duties
   48
                                                                              48



and obligations hereunder by reason of such resignation or such removal) shall,
or any Secured Party may, apply to any court of competent jurisdiction to
appoint a successor collateral agent or collateral agents to act hereunder.
Any successor collateral agent or collateral agents so appointed by such court
shall immediately and without further act be superseded by any successor
collateral agent or collateral agents appointed by the Majority Holders upon
the acceptance of such appointment by such successor collateral agent or
collateral agents.

                 (b)      If at any time the Collateral Agent shall resign or
otherwise become incapable of acting, or if at any time a vacancy shall occur
in the office of the Collateral Agent by virtue of the removal of the
Collateral Agent pursuant to clause (ii) of Section 8.5(a) or for any other
cause, a successor collateral agent or collateral agents may be appointed by
the Majority Holders, and the powers, duties, authority and title of the
predecessor collateral agent or collateral agents shall be terminated and
cancelled without procuring the resignation of such predecessor collateral
agent or collateral agents, and without any other formality (except as may be
required by applicable law).

                 (c)      The appointment and designation referred to in
subsection 8.5(b) shall, after any required filing, be full evidence of the
right and authority to make the same and of all the facts therein recited, and
this Agreement shall vest in such successor collateral agent or collateral
agents, without any further act, deed or conveyance, all of the estate and
title of its predecessor or their predecessors, and upon such filing for record
the successor collateral agent or collateral agents shall become fully vested
with all the estates, properties, rights, powers, trusts, duties, authority and
title of its predecessor or their predecessors; but such predecessor or
predecessors shall, nevertheless, on the written request of the Majority
Holders, the Companies or its or their successor collateral agent or collateral
agents, execute and deliver an instrument transferring to such successor or
successors all the estates, properties, rights, powers, trusts, duties,
authority and title of such predecessor or predecessors hereunder.  Each such
predecessor or predecessors shall deliver all securities and moneys held by it
or them to such successor collateral agent or collateral agents.
   49
                                                                              49




                 (d)      Any required filing for record of the instrument
appointing a successor collateral agent or collateral agents as hereinabove
provided shall be at the expense of the Companies.  The resignation of any
collateral agent or collateral agents and the instrument or instruments
removing any collateral agent or collateral agents, together with all other
instruments, deeds and conveyances provided for in this Article 8 shall, if
required by law, be forthwith recorded, registered and filed by and at the
expense of the Companies, wherever this Agreement is recorded, registered and
filed.

                 8.6      Status of Successors to the Collateral Agent.  Every
successor to the Collateral Agent appointed pursuant to Section 8.5 shall be a
bank or trust company in good standing and having power so to act, incorporated
under the laws of the United States or any State thereof or the District of
Columbia, and having its principal corporate trust office within the 48
contiguous States, and shall also have capital, surplus and undivided profits
of not less than $100,000,000, if there be such an institution with such
capital, surplus and undivided profits willing, qualified and able to accept
the trust upon reasonable or customary terms.

                 8.7      Merger of the Collateral Agent.  Any corporation into
which the Collateral Agent may be merged, or with which it may be consolidated,
or any corporation resulting from any merger or consolidation to which the
Collateral Agent shall be a party, shall be the Collateral Agent under this
Agreement without the execution or filing of any paper or any further act on
the part of the parties hereto.

                 8.8      Appointment of Additional and Separate Collateral
Agent.  Whenever (i) the Collateral Agent shall deem it necessary or prudent
(in accordance with the advice or opinion of its counsel) in order to conform
to any law of any jurisdiction in which all or any part of the Collateral shall
be situated or to make any claim or bring any suit with respect to or in
connection with the Collateral, or (ii) the Collateral Agent shall be advised
by counsel satisfactory to it that it is so necessary or prudent in the
interest of the Secured Parties, then, in any such case, the Collateral Agent
shall execute and deliver from time to time all instruments and agreements
necessary or proper to
   50
                                                                              50



constitute another bank or trust company or one or more Persons approved by the
Collateral Agent either to act as additional trustee or trustees of all or any
part of the Trust Estate, jointly with the Collateral Agent, or to act as
separate trustee or trustees of all or any part of the Trust Estate, in any
such case with such powers as may be provided in such instruments or
agreements, and to vest in such bank, trust company or Person as such
additional trustee or separate trustee, as the case may be, any property,
title, right or power of the Collateral Agent deemed necessary or advisable by
the Collateral Agent.  The Companies and the Secured Parties hereby consent to
all actions taken by the Collateral Agent under the foregoing provisions of
this Section 8.8.


                                   ARTICLE 9

                        CERTAIN INTERCREDITOR PROVISIONS

                 9.1  Contesting Liens or Security Interest.  The Collateral
Agent, each Secured Party and, by acceptance of the benefits of this Agreement
and the Collateral Documents, each Person for whom a Secured Party acts as
trustee, agent or fiduciary, as applicable, hereby agree that (a) the liens and
security interests granted to the Collateral Agent under the Collateral
Documents shall be treated, as among the Secured Parties and each of such
Persons, as having equal priority and shall at all times be shared by the
Secured Parties as provided herein, regardless of any claim or defense
(including, without limitation, any claims under the fraudulent transfer,
preference or similar avoidance provisions of applicable bankruptcy, insolvency
or other laws affecting the rights of creditors generally) to which the
Collateral Agent or any Secured Party or any of such Persons may be entitled or
subject and (b) none of them shall contest the validity, perfection, priority
or enforceability of any lien or security interest granted to the Collateral
Agent.

                 9.2  No Additional Rights for Companies Hereunder.  If a
Secured Party shall enforce its rights or remedies in violation of the terms of
this Agreement, the Companies agree that they shall not raise such violation as
a defense to collection or
   51
                                                                              51



enforcement by the other Secured Party with respect to the Indenture Obligation
or the Term Loan Obligation, as the case may be, or assert such violation as a
counterclaim or basis for setoff or recoupment against either Secured Party.

                 9.3  Concerning Collateral Agent.  Notwithstanding anything to
the contrary set forth herein, no provision of this Agreement shall require the
Collateral Agent to expend or risk its own funds or otherwise incur any
financial liability in the performance of its duties hereunder, or in the
exercise of any of its powers if it shall have reasonable grounds for believing
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                 9.4  Authority.  Each of the parties hereto represents and
warrants to all other parties hereto that the execution, delivery and
performance by or on behalf of such party of this Agreement has been duly
authorized by all necessary action, corporate or otherwise, does not violate
any provision of law, governmental regulation, or any agreement or instrument
by which such party is bound, and requires no governmental or other consent
that has not been obtained and is not in full force and effect.


                                   ARTICLE 10

                   TERMINATION; EXPIRATION OF CERTAIN RIGHTS

                 10.1  Termination.  This Agreement shall terminate when all
amounts owing in respect of all the Secured Obligations shall have been paid in
full in cash.

                 10.2  Amendment of Collateral Documents.  Subject to the
requirements of Sections 2.2, 3.2(c) and 4.5 hereof, the Majority Holders
(provided that the Majority Holders include the Term Loan Note Majority
Holders) shall have the exclusive authority to direct the Collateral Agent to
amend, supplement or waive any provision of any Collateral Document or to
direct the Collateral Agent to forebear from enforcing any provision of any
Collateral Document; provided, however, that no such amendment, supplement or
waiver shall affect the right of any Secured Party
   52
                                                                              52



(or any Person for whom a Secured Part acts as trustee, agent or fiduciary) not
consenting thereto in writing to equal and ratable security under the
Collateral Documents.  In addition, no amendment or modification to any of the
Collateral Documents shall impose any additional obligations or
responsibilities upon any Secured Party or otherwise adversely effect its
rights hereunder without the consent of each of the Secured Parties affected
thereby.


                                   ARTICLE 11

                                 MISCELLANEOUS

                 11.1  Amendments to Financing Arrangements or to This
Agreement.  The Collateral Agent, the Term Loan Agent and the Trustee shall
each use its best efforts to notify the other or others of any amendment,
modification or waiver to any document evidencing or securing the Secured
Obligations, but the failure to do so shall not create a cause of action
against the party failing to give such notice or create any claim or right on
behalf of any third party.  Each of the parties shall, upon request of the
other or others, provide copies of all such modifications, amendments and
waivers and copies of all other documentation relevant to the Collateral.  All
modifications, amendments and waivers of this Agreement must be in writing and
duly executed by an authorized officer of the Collateral Agent and each Secured
Party to be binding and enforceable, and the written consent of the Companies
shall be required only if the amendment, modification or waiver would impose,
or have the effect of imposing, on the Companies, more restrictive covenants or
greater obligations than those applicable to the Companies under this
Agreement, which consent shall not be unreasonably withheld, provided, however,
the written consent of the Companies shall not be required with respect to an
amendment of this Agreement pursuant to clause (b) of Section 3.11.

                 11.2     Notices, Distributions and Payments.  (a) In each
