             SECTION IV - REPRESENTATIONS, WARRANTIES AND COVENANTS

                 Trustor hereby represents, warrants and covenants as follows:

                 (a)  Good Title; Authority and Validity.  Trustor has good and
marketable title to the Mortgaged Property and the landlord's interest and
estate under or in respect of the Leases, subject to the Excepted Liens, and
has, in all material respects, full corporate power and lawful authority to
bargain, grant, sell, mortgage, assign, transfer, convey and grant a security
interest in all of the Mortgaged Property all in the manner and form herein
provided and without obtaining the waiver, consent or approval of any lessor,
sublessor, Governmental Authority or entity or other party whomsoever or
whatsoever which has not been obtained, except in the case of certain
environmental permits and approvals which, by their terms, are not transferable
or cannot be transferred without the prior approval of the issuing agency.  The
Improvements upon the Land are all within the boundary lines of the Land except
as set forth on Schedule 1 attached hereto or have the benefit of valid
easements, and there are no encroachments thereon that would materially impair
the use thereof.  The Mortgaged Property is free and clear of any and all Liens
or encumbrances of any nature or kind except for the Excepted Liens and the
Leases.  Trustor has all necessary permits, franchises, licenses,
rights-of-way, servitudes or other rights or authority needed in connection
with the operation and maintenance of the Chlor Alkali Plant, except where the
failure to have the same would not have a Material Adverse Effect; all of the
Plant Agreements are presently in full force and effect and no default has
occurred or exists thereunder, except where such default would not individually
or in the aggregate have a Material Adverse Effect; except as provided in the
Excepted Liens, Trustor's grant of a Lien and security interest in the
Mortgaged Property in the manner herein provided does not result in the
creation or imposition of any other Lien or security interest, adverse claim or
option upon any of the Mortgaged Property.  Trustor's chief executive





                                      -10-
   12
office and chief place of business is located at the address set forth in the
initial paragraph of this Deed of Trust.  Trustor will not change its name,
identity or corporate structure or its chief executive office or chief place of
business without notifying the Deed of Trust Trustee and Beneficiary at least
thirty (30) days prior to the effective date of such change.

                 (b)  Defense of Title.  Trustor will warrant and defend title
to the Mortgaged Property, subject to Excepted Liens, against the claims and
demands of all other Persons whomsoever and will maintain and preserve the Lien
created hereby so long as any of the Secured Obligations secured hereby remains
unpaid.  Should an adverse claim be made against the title to any material part
of the Mortgaged Property, Trustor agrees it will immediately notify
Beneficiary in writing thereof and defend against such adverse claim to the
extent necessary to preserve the Deed of Trust Trustee's and Beneficiary's
rights and benefits hereunder, subject to Excepted Liens, and Trustor further
agrees that the Deed of Trust Trustee and/or Beneficiary may take such other
reasonable action as they deem advisable to protect and preserve their
interests in the Mortgaged Property, and in such event Trustor will indemnify
the Deed of Trust Trustee and Beneficiary against any and all costs, reasonable
attorney's fees and other expenses which they may incur in defending against
any such adverse claim.  Such obligations shall be payable on demand and shall
bear interest from the date of demand therefor until paid at the Note Rate.
Any proceeds of any policy of title insurance maintained by Trustor with
respect to the Mortgaged Property shall, for the purposes of this Deed of
Trust, be paid and applied in the same manner as Insurance Proceeds (as
hereinafter defined).

                 (c)  First Lien.  This Deed of Trust is, and always will be
kept, a direct first Lien and security interest upon the Mortgaged Property,
subject to the Excepted Liens, and Trustor will not create or suffer to be
created or permit to exist any Lien, security interest or charge prior or
junior to or on parity with the Lien and security interest of this Deed of
Trust upon the Mortgaged Property or any part thereof or upon the rents,
issues, revenues, profits or other income therefrom, except for the Excepted
Liens.

                 (d)  Maintenance of Mortgaged Property.  Trustor will at its
own expense do or cause to be done all things necessary to preserve and keep in
full repair, working order and efficiency,





                                      -11-
   13
reasonable wear and tear excepted, all of the Mortgaged Property, including,
without limitation, all equipment, machinery and facilities, and from time to
time will make all the needful and proper repairs, renewals and replacements so
that at all times the state and condition of the Mortgaged Property will be
fully preserved and maintained, unless the failure to repair, renew or replace
would not materially interfere with the present use or operation of the
Mortgaged Property.

                 (e)  Performance of Contracts; Operation of Plant.  Trustor
will promptly pay and discharge all rentals, or other payments and will perform
or cause to be performed each and every act, matter or thing required by, each
and all of the contracts, instruments or agreements executed in connection with
or incident to the ownership and operation of the Chlor Alkali Plant (including
without limitation the Plant Agreements) and being a portion of the Mortgaged
Property and will do all other things necessary to keep unimpaired Trustor's
rights with respect thereto and to prevent any forfeiture thereof or default
thereunder, unless such forfeiture or default would not individually or in the
aggregate have a Material Adverse Effect.  Trustor will operate the facilities
comprising the Chlor Alkali Plant in a good and workmanlike manner and in
accordance with the practices of the industry and in compliance in all material
respects with all Governmental Requirements affecting ownership and operation
of such facilities, including without limitation, Environmental Laws.

                 (f)  Payment by the Trustee and/or Beneficiary.  Trustor
agrees that if Trustor fails to perform any act or to take any action which
Trustor is required to perform or take hereunder or pay any money which Trustor
is required to pay hereunder (taking into account applicable grace or cure
periods), the Deed of Trust Trustee and/or Beneficiary in Trustor's name or its
own name may, but shall not be obligated to, during the continuance of an Event
of Default, perform or cause to perform such act or take such action or pay
such money, and any expenses so incurred by the Deed of Trust Trustee or
Beneficiary and any money so paid by the Deed of Trust Trustee or Beneficiary
shall be a demand obligation owing by Trustor to the Deed of Trust Trustee or
Beneficiary, and the Deed of Trust Trustee or Beneficiary, upon making such
payment, shall be subrogated to all





                                      -12-
   14
of the rights of the Person receiving such payment.  Each amount due and owing
by Trustor to holders of the Secured Obligations and/or the Deed of Trust
Trustee pursuant to this Deed of Trust shall bear interest from the date of
such expenditure or payment or other occurrence which gives rise to such amount
being owed to the Deed of Trust Trustee or Beneficiary until paid at the Note
Rate, and all such amounts together with such interest thereon shall be a part
of the Secured Obligations and shall be secured by this Deed of Trust.

                 (g)  Name of Trustor.  Trustor does not do business with
respect to the Mortgaged Property under any name other than Pioneer Chlor
Alkali Company, Inc.

                 (h)  Operation by Third Parties.  To the extent any of the
Mortgaged Property is operated by a party or parties other than Trustor,
Trustor's covenants as expressed in this Section IV are modified to require
that Trustor use its best efforts (including without limitation the reasonable
exercise of all rights and remedies as are available to Trustor) to obtain
compliance with such covenants by the operator or operators of the Mortgaged
Property.

                 (i)      Compliance with Laws.  The Chlor Alkali Plant
complies in all material respects with all local zoning, land use, setback and
other development, use and occupancy requirements of governmental authorities
except for possible nonconforming uses or violations which do not and will not
materially interfere with the present use, operation or maintenance thereof as
now used, operated or maintained.

                 (j)  Payment of Taxes, Insurance Premiums, Assessments;
Compliance with Law and Insurance Requirements.  (i)  Unless contested in
accordance with the provisions of subsection IV(j)(v) hereof, Trustor shall pay
and discharge or cause to be paid and discharged, from time to time when the
same shall become due, all real estate and other taxes, special assessments,
levies, permits, inspection and license fees, all premiums for insurance, all
water and sewer rents and charges, and all other public charges imposed upon or
assessed against the Mortgaged Property or any part thereof or upon the
revenues, rents, issues, income and profits of the Mortgaged Property,
including, without





                                      -13-
   15
limitation, those arising in respect of the occupancy, use or possession
thereof.

             (ii)         During the continuance of an Event of Default,
Trustor shall deposit with Beneficiary, on the first day of each month, an
amount reasonably estimated by Trustor to be equal to one-twelfth (1/12th) of
the annual taxes, assessments and other items required to be discharged by
Trustor under subsection IV(j)(i) and amounts reasonably estimated by Trustor
to be necessary to maintain the insurance coverages contemplated in subsection
IV(l) below, which estimates shall not be less than one-twelfth (1/12th) of the
annual taxes, assessments, insurance premiums and other items required to be
discharged by Trustor during the year immediately preceding the year during
which such Event of Default occurred.  Such amounts shall be held by
Beneficiary without interest to Trustor and applied to the payment of each
obligation in respect of which such amounts were deposited, in such order or
priority as Beneficiary shall determine, on or before the date on which such
obligation would become delinquent.  If at any time the amounts so deposited by
Trustor shall, in Beneficiary's judgment, be insufficient (when added to the
installments anticipated to be paid thereafter) to discharge any of such
obligations when due, Trustor shall, immediately upon demand, deposit with
Beneficiary such additional amounts as may be requested by Beneficiary.
Nothing contained in this subsection IV(j) shall affect any right or remedy of
the Deed of Trust Trustee or Beneficiary under any provision of this Deed of
Trust or of any statute or rule of law to pay any such amount from its own
funds (provided, however, that neither the Deed of Trust Trustee nor
Beneficiary shall in any event be obligated to pay any of such amounts from its
own funds) and to add the amount so paid, together with interest at the Note
Rate, to the Secured Obligations, or relieve Trustor of its obligations to make
or provide for the payment of the annual taxes, assessments and other charges
required to be discharged by Trustor under subsection IV(j)(i).  Trustor hereby
grants to Beneficiary a security interest in all sums held pursuant to this
subsection IV(j)(ii) to secure payment and performance of the Secured
Obligations.  During the continuance of any Event of Default, Beneficiary may
apply all or any part of the sums held pursuant to this subsection IV(j)(ii) to
payment and performance of the Secured Obligations in accordance with the
provisions of





                                      -14-
   16
the Intercreditor Agreement.  Trustor shall redeposit with Beneficiary an
amount equal to all amounts so applied as a condition to the cure, if any, of
such Event of Default, in addition to fulfillment of any other required
conditions.

            (iii)  Unless contested in accordance with the provisions of
subsection IV(j)(v), Trustor shall timely pay (or obtain a bond in the amount
of) all lawful claims and demands of mechanics, materialmen, laborers,
warehousemen, employees, suppliers, government agencies administering worker's
compensation insurance, old age pensions and social security benefits and all
other claims, judgments, demands or amounts of any nature which, if unpaid or
not bonded, could result in or permit the creation of a Lien (other than an
Excepted Lien) on the Mortgaged Property or any part thereof or the Rents
arising therefrom, or which might result in forfeiture of all or any part of
the Mortgaged Property.

             (iv)  Trustor shall maintain, or cause to be maintained, in full
force and effect, all permits, certificates, authorizations, consents,
approvals, registrations, filings, licenses, franchises or other instruments
now or hereafter required by any Governmental Authority to operate or use and
occupy the Chlor Alkali Plant and the Equipment for its intended uses
(collectively, the "Permits"; each, a "Permit"), unless the failure to maintain
such Permits would not individually or in the aggregate have a Material Adverse
Effect.  Trustor represents that, to its knowledge and subject to those
requirements for notice, approval or reissuance set forth by applicable law,
none of the Permits will be subject to cancellation, forfeiture or any
limitation on the scope thereof solely by virtue of the execution of this Deed
of Trust or the foreclosure of the Lien hereof.  Unless contested in accordance
with the provisions of subsection IV(j)(v), Trustor shall comply promptly with,
or cause prompt compliance with, all requirements set forth in the Permits and
all Governmental Requirements applicable to all or any part of the Mortgaged
Property or the condition, use or occupancy of all or any part thereof or any
recorded deed of restriction, declaration, covenant running with the land or
otherwise, now or hereafter in force unless the compliance therewith would not
individually or in the aggregate have a Material Adverse Effect.  Trustor shall
not initiate or consent to any change in the





                                      -15-
   17
zoning, subdivision or any other use classification of the Land, if such action
could have a material adverse effect on the Lien of this Deed of Trust or
materially impair the present use and operation of the Mortgaged Property or
materially impair Beneficiary's rights or benefits hereunder, without the prior
written consent of Beneficiary.

                 (v)  Trustor may at its own expense contest the amount or
applicability of any of the obligations described in subsections IV(j)(i),
IV(j)(iii) and IV(j)(iv) by appropriate legal proceedings, prosecution of which
operates to prevent the collection or enforcement thereof or the sale or
forfeiture of the Mortgaged Property or any part thereof to satisfy such
obligations; provided, however, that (A) any such contest shall be conducted in
good faith by appropriate legal proceedings promptly instituted and diligently
conducted and (B) in connection with such contest, Trustor shall have made
provision for the payment or performance of such contested obligation on
Trustor's books if and to the extent required by generally accepted accounting
principles then utilized by Trustor in the preparation of its financial
statements, or shall have deposited with Beneficiary a sum sufficient to pay
and discharge such obligation and Beneficiary's estimate of all interest and
penalties related thereto.  Notwithstanding the foregoing provisions of this
subsection IV(j)(v), (A) no contest of any such obligations may be pursued by
Trustor if such contest would expose the Deed of Trust Trustee, Beneficiary, or
any other Secured Party to any possible criminal liability or, unless Trustor
shall have furnished an Additional Undertaking (as hereinafter defined)
therefor satisfactory to the Deed of Trust Trustee, Beneficiary, or such other
Secured Party, as the case may be, any civil liability for failure to comply
with such obligations and (B) if at any time payment or performance of any
obligation contested by Trustor pursuant to this subsection IV(j)(v) shall
become necessary to prevent the delivery of a tax or similar deed conveying the
Mortgaged Property or any portion thereof because of nonpayment or
nonperformance, Trustor shall pay or perform the same in sufficient time to
prevent the delivery of such tax or similar deed.

             (vi)  Trustor shall not in its use and occupancy of the Chlor
Alkali Plant or the Equipment (including, without





                                      -16-
   18
limitation, in the making of any Alteration) take any action that would cause
the termination, revocation or denial of any insurance coverage required to be
maintained under this Deed of Trust or that pursuant to written notice from any
applicable insurer, would be the basis for a defense to any claim under any
insurance policy maintained in respect of the Chlor Alkali Plant or the
Equipment and Trustor shall otherwise comply in all material respects with the
requirements of any insurer that issues a policy of insurance in respect of the
Chlor Alkali Plant or the Equipment.

            (vii)  Trustor shall, promptly upon receipt of any written notice
regarding any failure by Trustor to pay or discharge any of the obligations
described in subsection IV(j)(i) or (vi), furnish a copy of such notice to
Beneficiary.  Trustor shall, promptly upon receipt of any written notice
regarding any failure by Trustor to pay or discharge any of the obligations
described in subsection IV(j)(iii) or (iv), furnish a copy of such notice to
Beneficiary, if such failure would have a Material Adverse Effect.

                 (k)  Certain Tax Law Changes.  In the event of the passage
after the date of this Deed of Trust of any law deducting from the value of
real property, for the purpose of taxation, amounts in respect of any Lien
thereon or changing in any way the laws for the taxation of deeds of trust or
debts secured by deeds of trust for state or local purposes or the manner of
the collection of any such taxes, and imposing a new tax, either directly or
indirectly, on this Deed of Trust or the interest of any Secured Party in any
Mortgaged Property (other than income, franchise or similar taxes imposed on
such Secured Party), or in the event that any regulation or regulatory
amendment becoming effective after the date hereof imposes any State tax on
interest income received with respect to any Secured Obligation, Trustor shall
promptly pay the applicable Secured Party such amount or amounts as may be
necessary from time to time to pay such tax.

                 (l)  Required Insurance Policies.  (i)  Trustor shall
maintain, or cause to be maintained, in full force and effect the following
insurance coverages in respect of the Chlor Alkali Plant and the Equipment:





                                      -17-
   19
                 (A)  Physical hazard insurance on an "all risk" basis covering
         hazards commonly covered by fire and extended coverage, lightning,
         civil commotion, hail, riot, strike, water damage, sprinkler leakage,
         collapse and malicious mischief, in an amount equal to the full
         replacement cost of the Improvements and all Equipment, with such
         deductibles as would be maintained by a prudent operator of property
         similar in use and configuration to the Chlor Alkali Plant and located
         in the locality where the Chlor Alkali Plant is located.  "Full
         replacement cost" means the cost of construction to replace the
         Improvements and the Equipment, exclusive of depreciation, excavation,
         foundation and footings, as determined from time to time by a proper
         officer of Trustor in consultation with its insurance company or
         insurance agent, as appropriate;

                 (B)  Comprehensive general liability insurance against claims
         for bodily injury, death or property damage occurring on, in or about
         the Chlor Alkali Plant and any adjoining streets, sidewalks and
         passageways and covering any and all claims, including, without
         limitation, all legal liability, subject to customary exclusions, to
         the extent insurable, imposed upon Beneficiary or any Secured Party
         and all court costs and attorneys' fees, arising out of or connected
         with the possession, use, leasing, operation or condition of the Chlor
         Alkali Plant, with policy limits and deductibles in such amounts as
         would be maintained by a prudent operator of property similar in use
         and configuration to the Chlor Alkali Plant and located in the
         locality where the Chlor Alkali Plant is located;

                 (C)  Workers' compensation insurance as required by the laws
         of the State to protect Trustor against claims for injuries sustained
         in the course of employment at the Chlor Alkali Plant;

                 (D)  Comprehensive boiler and machinery insurance to cover
         sudden and accidental breakdown, including but not limited to,
         explosion of any boilers and machinery located on the Chlor Alkali
         Plant or comprising any Equipment, with policy limits and deductibles
         in such amounts as would be maintained by a prudent operator of
         property similar in use





                                      -18-
   20
         and configuration to the Chlor Alkali Plant and the Equipment and

                 (E)      Comprehensive automobile liability insurance policy
         against claims for bodily injury, death and property damage covering
         all owned, leased, non-owned and hired motor vehicles, including
         loading and unloading in such amounts as would be maintained by a
         prudent operator of property similar in use and configuration to the
         Chlor Alkali Plant and the Equipment and located in the locality where
         the Chlor Alkali Plant is located;

                 (F)      Business interruption insurance on an annual basis in
         amounts not less than the projected gross profit of the Chlor Alkali
         Plant during the applicable twelve-month period but in no event less
         than the amount necessary to pay the fixed charges and other expenses
         of owning, operating and maintaining the Mortgaged Property for the
         same period;

                 (G)  To the extent not otherwise covered by the insurance
         required under clauses (A) and (B) of this subsection IV(l)(i), during
         the performance of any alterations, renovations, repairs, restorations
         or construction, broad form Builders Risk Insurance on an all-risk
         completed value basis; and

                 (H)  Such other insurance, against such risks and with policy
         limits and deductibles in such amounts as would be maintained by a
         prudent operator of property similar in use and configuration to the
         Chlor Alkali Plant and located in the locality in which the Chlor
         Alkali Plant is located.

                 (ii)   Trustor may maintain the coverages required by this
subsection IV(l) under blanket policies covering the Chlor Alkali Plant and
other locations owned or operated by Trustor if the terms of such blanket
policies otherwise comply with the provisions of this subsection IV(l) and
contain specific coverage allocations in respect of the Chlor Alkali Plant
determined in accordance with the provisions of this subsection IV(l).  All
insurance policies in respect of the coverages required by subsections
IV(l)(i)(A), IV(l)(i)(D), IV(l)(i)(G) and, if





                                      -19-
   21
applicable, IV(l)(i)(H) shall be in amounts at least sufficient to prevent
coinsurance liability and all losses thereunder shall be payable to
Beneficiary, as loss payee, subject to the terms of the Intercreditor
Agreement, pursuant to a standard noncontributory New York mortgage endorsement
or local equivalent, and each such policy shall, to the extent obtainable at
commercially reasonable costs, (A) include effective waivers (whether under the
terms of such policy or otherwise) by the insurer of all claims for insurance
premiums against all loss payees and named insureds other than Trustor and all
rights of subrogation against any named insured, and (B) provide that any
losses thereunder shall be payable notwithstanding (1) any act, failure to act,
negligence of, or violation or breach of warranties, declarations or conditions
contained in such policy by Trustor or Beneficiary or any other named insured
or loss payee, (2) the occupation or use of the Chlor Alkali Plant or the
Equipment for purposes more hazardous than permitted by the terms of the
policy, (3) any foreclosure or other proceeding or notice of sale relating to
the Chlor Alkali Plant or the Equipment or (4) any change in the title to or
ownership or possession of the Chlor Alkali Plant or the Equipment; provided,
however, that (with respect to items contemplated in clauses (3) and (4) above)
any notice requirements of the applicable policies are satisfied.  All
insurance policies in respect of the coverages required by subsections
IV(l)(i)(B), IV(l)(i)(E) and, if applicable, IV(l)(i)(H) shall name Beneficiary
as an additional insured.  Each policy of insurance required under this
subsection IV(l) shall provide that (A) notices of any failure by Trustor to
pay any insurance premium in respect thereof, be furnished to Beneficiary
contemporaneously with any such notice given to Trustor and (B) it may not be
cancelled or otherwise terminated without at least twenty (20) days' prior
written notice to Beneficiary and shall permit Beneficiary to pay any premium
therefor within twenty (20) days after receipt of any notice stating that such
premium has not been paid when due.  The policy or policies of such insurance
or certificates of insurance evidencing the required coverages and all renewals
or extensions thereof shall be delivered to Beneficiary upon receipt by
Trustor.  Settlement of any claim under any of the insurance policies referred
to in this subsection IV(l) (other than the insurance contemplated in clause(C)
of this subsection IV(l)(i)) which in Trustor's reasonable judgment involves
loss of





                                      -20-
   22
$1,000,000 or more, shall require the prior approval of Beneficiary (acting
pursuant to the provisions of the Intercreditor Agreement) and Trustor shall
use its best efforts to cause each such insurance policy to contain a provision
to such effect.

                 (iii)  At least fifteen (15) days prior to the expiration of
any insurance policy required by this subsection IV(l), Trustor shall deliver
to Beneficiary evidence that such policy or policies shall be renewed or
extended and Trustor shall deliver promptly to Beneficiary after receipt
thereof the policy or policies renewing or extending such expiring policy or
renewal or extension certificates or other evidence of renewal or extension,
together with a receipt showing payment of the premium thereof.

                 (iv)  Trustor shall not purchase additional policies in
respect of the insurance coverages required to be maintained under this
subsection IV(l), unless Beneficiary is included thereon as an additional named
insured and, if applicable, with loss payable to Beneficiary under an
endorsement containing the provisions described in subsection IV(l)(ii) and the
policy evidencing such insurance otherwise complies with the requirements of
subsection IV(l)(ii).  Trustor immediately shall notify Beneficiary whenever
any such separate insurance policy is obtained and promptly shall deliver to
Beneficiary the policy or certificate evidencing such insurance.

                 (m)  Inspection.  Trustor shall permit Beneficiary, by its
agents, accountants and attorneys, to visit and inspect the Mortgaged Property
upon reasonable prior notice at such times as may be reasonably requested by
Beneficiary.

                 (n)  Trustor To Maintain Improvements.  Trustor shall not
commit any waste on the Chlor Alkali Plant or with respect to any Equipment or
make any change in the use of the Chlor Alkali Plant or any Equipment.  Trustor
represents and warrants that (i) to Trustor's knowledge, the Chlor Alkali Plant
is served by all electric, gas, sewer, water facilities and any other utilities
required or necessary for the current use thereof and any easements or
servitudes necessary to the furnishing of such utility service by Trustor have
been obtained and duly recorded,





                                      -21-
   23
and (ii) Trustor has access to the Chlor Alkali Plant from public roads
sufficient to allow Trustor and its tenants and invitees to conduct its and
their businesses at the Chlor Alkali Plant as it is currently conducted.
Trustor shall not materially alter the occupancy or use of the Chlor Alkali
Plant without the prior written consent of Beneficiary.  Except as otherwise
permitted by the Intercreditor Agreement no Improvements comprising a portion
of the Chlor Alkali Plant may be demolished nor shall any Equipment be removed
without the prior written consent of Beneficiary.

                 (o)  Leases.  (i)  All of the Leases are valid and effective
in accordance with their respective terms, except that the enforcement thereof
may be subject to (i) bankruptcy, insolvency, reorganization, moratorium or
other similar law affecting or relating to enforcement of creditors' rights
generally, and (ii) general equitable principles.  To Trustor's knowledge,
Trustor is not in material breach of or in default (and to Trustor's knowledge,
no event has occurred which with due notice or lapse of time or both, may
constitute such a material breach or default) under any Lease, and no party to
any Lease has given Trustor written notice of or made a claim with respect to
any breach or default, the consequences of which, individually or in the
aggregate, would have a Material Adverse Effect on Trustor.

                 (ii)  Trustor shall manage and operate the Mortgaged Property
or cause the Mortgaged Property to be managed and operated in a reasonably
prudent manner and, except as otherwise permitted under subsection IV(p), will
not enter into any Lease (or any amendment or modification thereof) or other
agreement subsequent to the date hereof with any Person which, in the
reasonable judgment of Trustor, individually or in the aggregate, would have a
Material Adverse Effect on the value of the property subject thereto.

                 (iii)  Trustor shall not:

                 (A)  receive or collect, or permit the receipt or collection
         of, any rental or other payments under any Lease more than one (1)
         month in advance of the respective period in respect of which they are
         to accrue, except that (a) in





                                      -22-
   24
         connection with the execution and delivery of any Lease or of any
         amendment to any Lease, rental payments thereunder may be collected
         and received in advance in an amount not in excess of one (1) month's
         rent and (b) Trustor may receive and collect escalation and other
         charges in accordance with the terms of each Lease;

                 (B)  assign, transfer or hypothecate (other than to
         Beneficiary hereunder or as otherwise permitted under subsection IV(p)
         of this Deed of Trust) any rental or other payment under any Lease
         whether then due or to accrue in the future, the interest of Trustor
         as lessor under any Lease or the rents, issues, revenues, profits or
         other income of the Mortgaged Property;

                 (C)  enter into any Lease after the date hereof that does not
         contain terms to the effect as follows:

                          (1)  such Lease and the rights of the tenant
                 thereunder shall be subject and subordinate to the rights of
                 Beneficiary under and the Lien of this Deed of Trust;

                          (2)  such Lease has been assigned as collateral
                 security by Trustor as landlord thereunder to Beneficiary
                 under this Deed of Trust;

                          (3)  in the case of any foreclosure hereunder, the
                 rights and remedies of the tenant in respect of any
                 obligations of any successor landlord thereunder shall be
                 limited to the equity interest of such successor landlord in
                 the Chlor Alkali Plant and any successor landlord shall not
                 (a) be liable for any act, omission or default of any prior
                 landlord under the Lease or (b) be required to make or
                 complete any tenant improvements or capital improvements or
                 repair, restore, rebuild or replace the demised premises or
                 any part thereof in the event of damage, casualty or
                 condemnation or (c) be required to pay any amounts to tenant
                 arising under the Lease prior to such successor landlord
                 taking possession;





                                      -23-
   25
                          (4)  the tenant's obligation to pay rent and any
                 additional rent shall not be subject to any abatement,
                 deduction, counterclaim or setoff as against Beneficiary or
                 any purchaser upon the foreclosure of any portion of the Chlor
                 Alkali Plant or the giving or granting of a deed in lieu
                 thereof by reason of a landlord default occurring prior to
                 such foreclosure, and Beneficiary or such purchaser will not
                 be bound by any advance payments of rent in excess of one
                 month or any security deposits unless such security was
                 actually received; and

                          (5)  the tenant agrees to attorn, at the option of
                 Beneficiary or any purchaser of the Chlor Alkali Plant, to the
                 successor owner upon a foreclosure of the Chlor Alkali Plant
                 or the giving or granting of a deed in lieu thereof; and

                 (D)  terminate or permit the termination of any Lease of
         space, accept surrender of all or any portion of the space demised
         under any Lease prior to the end of the term thereof or accept
         assignment of any Lease to Trustor which, in the reasonable judgment
         of Trustor, individually or in the aggregate, would have a Material
         Adverse Effect or materially impair the Lien of this Deed of Trust
         therein unless:

                          (1)  the tenant under such Lease has not paid the
                 equivalent of two months' rent and Trustor has made reasonable
                 efforts to collect such rent; or

                          (2)  Trustor shall deliver to Beneficiary an
                 Officers' Certificate to the effect that Trustor has entered
                 into a new Lease (or Leases) for the space covered by the
                 terminated or assigned Lease with a term (or terms) which
                 expire(s) no earlier than the date on which the terminated or
                 assigned Lease was to expire (excluding renewal options), and
                 with a tenant (or tenants) having a creditworthiness (as
                 reasonably determined by Trustor) sufficient to pay the rent
                 and other charges due under the new Lease (or Leases), and the
                 tenant(s) shall have commenced paying rent,





                                      -24-
   26
                 including, without limitation, all operating expenses and
                 other amounts payable under the new Lease (or Leases), without
                 any abatement or concession, in an amount at least equal to
                 the amount which would have then been payable under the
                 terminated or assigned Lease.

                 (iv)  Trustor timely shall perform and observe all the terms,
covenants and conditions required to be performed and observed by Trustor under
each Lease and will not engage in any conduct in respect of any Lease which
would have individually or in the aggregate a Material Adverse Effect or
materially impair the Lien of this Deed of Trust or the security interest
created hereby.  Trustor promptly shall notify Beneficiary of the receipt of
any notice from any lessee under any Lease claiming that Trustor is in material
default in the performance or observance of any of the terms, covenants or
conditions thereof to be performed or observed by Trustor and will cause a copy
of each such notice to be delivered promptly to Beneficiary.

                 (p)  Transfer Restrictions.  Except as otherwise permitted by
the Intercreditor Agreement, Trustor shall not, without the prior written
consent of Beneficiary, further mortgage, encumber, hypothecate, sell, convey
or assign all or any part of the Mortgaged Property or suffer any of the
foregoing to occur by operation of law or otherwise (each a "Transfer");
provided, however, Trustor may so encumber the Mortgaged Property to the extent
such encumbrances are of the kind listed in clause (e) of the definition of
"Excepted Liens".  Any proceeds of such permitted Transfer shall be deemed
Collateral Proceeds (as such term is defined in the Indenture) and are hereby
assigned and shall be paid to Beneficiary to be held in the Collateral Account
and disbursed pursuant to the Intercreditor Agreement.

                 (q)  Destruction; Condemnation.

                 (i)  Destruction; Insurance Proceeds.  If there shall occur
any damage to, or loss or destruction of, the Improvements and Equipment, or
any part of any thereof (each, a "Destruction"), Trustor shall promptly send to
Beneficiary a notice setting forth the nature and extent of such Destruction.
The proceeds of any insurance payable in respect of any such





                                      -25-
   27
Destruction are hereby assigned and shall be paid to Beneficiary to be held in
the Collateral Account; provided, however, that so long as no Event of Default
shall have occurred and be continuing, if such proceeds are in an amount less
than $1,000,000, such proceeds shall be paid directly to Trustor.  All
insurance proceeds paid to Beneficiary pursuant to this subsection, less the
amount of any expenses incurred in litigating, arbitrating, compromising or
settling any claim arising out of such Destruction (the "Insurance Proceeds"),
shall constitute Trust Moneys and be applied in accordance with the provisions
of subsections IV(q)(iii), IV(q)(iv) and IV(q)(v).

                 (ii)  Condemnation; Assignment of Award.  If there shall occur
any taking of the Mortgaged Property or any part thereof, in or by condemnation
or other eminent domain proceedings pursuant to any law, general or special, or
by reason of the temporary requisition of the use or occupancy of the Mortgaged
Property or any part thereof, by any governmental authority, civil or military
(each, a "Taking"), Trustor immediately shall notify Beneficiary upon receiving
notice of such Taking or commencement of proceedings therefor.  Beneficiary may
(but shall not be obligated to) participate in any proceedings or negotiations
which might result in any Taking. Beneficiary may be represented by counsel
satisfactory to it at the expense of Trustor.  Trustor shall deliver or cause
to be delivered to Beneficiary all instruments requested by it to permit such
participation.  Trustor shall in good faith and with due diligence file and
prosecute what would otherwise be Trustor's claim for any such award or payment
and cause the same to be collected and paid over to Beneficiary, and hereby
irrevocably authorizes and empowers Beneficiary, in the name of Trustor as its
true and lawful attorney-in-fact or otherwise, during the continuance of an
Event of Default to collect and to receipt for any such award or payment, and,
in the event Trustor fails so to act, to file and prosecute such claim.
Trustor shall pay all costs, fees and expenses incurred by Beneficiary in
connection with any Taking and seeking and obtaining any award or payment on
account thereof.  Any proceeds, award or payment in respect of any Taking are
hereby assigned and shall be paid to Beneficiary to be held in the Collateral
Account; provided, however, that so long as no Event of Default shall have
occurred and be continuing, if such proceeds are in an amount less than





                                      -26-
   28
$1,000,000, such proceeds shall be paid directly to Trustor.  Trustor shall
take all steps necessary to notify the condemning authority of such assignment.
Such proceeds, award or payment paid to Beneficiary, less the amount of any
expenses incurred in litigating, arbitrating, compromising or settling any
claim arising out of such Taking ("Net Award"), shall constitute Trust Moneys
and be applied in accordance with the provisions of subsections IV(q)(iii),
IV(q)(iv) and IV(q)(v).

                 (iii)  Payment or Restoration.  So long as no Event of Default
shall have occurred and be continuing, Trustor shall have the right, at
Trustor's option, to require Beneficiary to apply such Net Award or Insurance
Proceeds to the payment of the Secured Obligations, in accordance with the
Intercreditor Agreement or to perform a restoration (each, a "Restoration") of
the affected portions of the Chlor Alkali Plant and the Equipment.  In the
event that Trustor elects to make such payment, such Net Award or Insurance
Proceeds shall be delivered to the Beneficiary to be held as Trust Moneys
subject to withdrawal and application by Beneficiary in accordance with the
provisions of the Intercreditor Agreement.  In the event Trustor elects to
perform a Restoration, Trustor shall give written notice ("Restoration Election
Notice") of such election to Beneficiary within twenty (20) business days after
the date that Beneficiary receives the applicable Insurance Proceeds or Net
Award, as the case may be.  Trustor shall, within twenty (20) business days
following the date of delivery of a Restoration Election Notice, commence and
diligently continue to perform the Restoration of that portion or portions of
the Chlor Alkali Plant and Equipment subject to such Destruction or affected by
such Taking so that, upon the completion of the Restoration, the Mortgaged
Property shall be in the same condition and shall be of at least equal utility
for its intended purposes as the Mortgaged Property was immediately prior to
such Destruction or Taking.  Trustor shall so complete such Restoration with
its own funds to the extent that the amount of any Net Award or Insurance
Proceeds is insufficient for such purpose.  In the event Beneficiary does not
receive a Restoration Election Notice within such twenty (20) business day
period, Beneficiary shall apply such Insurance Proceeds or Net Award to the
payment of the Secured Obligations, in accordance with the provisions of the
Intercreditor Agreement.





                                      -27-
   29

                 (iv)  Restoration.  In the event a Restoration is to be
performed under this subsection IV(q)(iv), Beneficiary shall not release any
part of the Net Award or the Insurance Proceeds except in accordance with the
provisions of subsection IV(q)(v) and Trustor shall, prior to commencing any
work to effect a Restoration of the Chlor Alkali Plant and the Equipment,
promptly (but in no event later than one-hundred twenty (120) days following
any Destruction or Taking) furnish to Beneficiary:

                 (A)  complete plans and specifications (the "Plans and
         Specifications") for the Restoration;

                 (B)  an officers' certificate stating that all permits and
         approvals required by law to commence work in connection with the
         Restoration have been obtained;

                 (C)  a certificate (an "Architect's Certificate") of an
         independent, reputable architect or engineer acceptable to Beneficiary
         and licensed in the State (1) stating that the Plans and
         Specifications have been reviewed and approved by the signatory
         thereto, (2) containing such signatory's estimate (an "Estimate") of
         the costs of completing the Restoration, and (3) upon completion of
         such Restoration in accordance with the Plans and Specifications, the
         utility of the Chlor Alkali Plant and the Equipment will be equal to
         or greater than the utility thereof immediately prior to the
         Destruction or Taking relating to such Restoration; and

                 (D)  if the Estimate exceeds the Insurance Proceeds or the Net
         Award, as the case may be, by $5,000,000 or more, an Additional
         Undertaking in an amount equal to not less than the Estimate less the
         amount of the Insurance Proceeds or the Net Award, as the case may be,
         then held by Beneficiary for application toward the cost of such
         Restoration.

                 Upon receipt by Beneficiary of each of the items required
pursuant to clauses (A) through (D) above, Beneficiary shall acknowledge
receipt of the Plans and Specifications.  Promptly upon such acknowledgment of
receipt by Beneficiary, Trustor shall commence and diligently continue to
perform the Restoration substantially in accordance with such Plans and
Specifications and in material compliance with all Governmental





                                      -28-
   30
Requirements, free and clear of all Liens except Excepted Liens.  Trustor shall
so complete such Restoration with its own funds to the extent that the amount
of any Net Award or Insurance Proceeds is insufficient for such purpose.

                 (v)  Restoration Advances Following Destruction or Taking of
Mortgaged Property.  In the event Trustor performs a Restoration of the Chlor
Alkali Plant and Equipment as provided in subsection IV(q)(iv), Beneficiary
shall apply any Insurance Proceeds or Net Award held by Beneficiary on account
of the Destruction or Taking to the payment of the cost of performing such
Restoration pursuant to the relevant provisions of the Intercreditor Agreement.
In the event there shall be any surplus after application of the Net Award or
the Insurance Proceeds to Restoration of the Chlor Alkali Plant and the
Equipment, such surplus shall become Net Proceeds, as defined in the Indenture
and shall be paid by Beneficiary to the Note Trustee for application in
accordance thereunder; provided, however, that if an Event of Default shall
have occurred and be continuing, such surplus shall be applied by Beneficiary
to the payment of the Secured Obligations, in accordance with Article 6 of the
Intercreditor Agreement.  Notwithstanding anything to the contrary herein, if a
Destruction or Taking of all or substantially all of the Mortgaged Property
occurs on a date which is less than 12 months prior to Maturity, as such term
is defined in the Indenture, all Insurance Proceeds and Net Awards shall be
applied to the permanent repayment or prepayment of any Secured Obligations
then outstanding in accordance with the Intercreditor Agreement.

                 (r)  Alterations.  Trustor shall not make any material
structural addition, modification or change (each, an "Alteration") to the
Chlor Alkali Plant or the Equipment which would materially diminish the utility
of the Mortgaged Property or impair the Lien of this Deed of Trust thereon.
Whether or not Beneficiary has consented to the making of any Alteration,
Trustor shall (i) complete each Alteration promptly, in a good and workmanlike
manner and in material compliance with all applicable local laws, ordinances
and requirements and (ii) pay when due all claims for labor performed and
materials furnished in connection with such Alteration, unless contested in
accordance with the provisions of subsection IV(j)(v).





                                      -29-
   31
                 (s)  Hazardous Material.

                 (i)  Except with respect to those matters which would not
reasonably be expected to have a Material Adverse Effect, to the best knowledge
of Trustor, Trustor holds all Permits required to permit Trustor to conduct its
business in the manner now conducted and none of the Trustor's operations are
being conducted in a manner that violates in any material respect the terms and
conditions under which any such Permit was granted, including without
limitation, under any Environmental Laws, except those permits that are
expected to be transferred in the ordinary course after the date hereof; to the
best knowledge of Trustor all such Permits are valid and in full force and
effect; and to the knowledge of Trustor, no suspension, cancellation,
revocation or termination of any such Permit is threatened.

                 (ii)  Except as set forth in the Term Loan Agreement, there
are no material claims, actions, suits, proceedings or investigations pending
or to the knowledge of Trustor, threatened, before any Governmental Authority
or before any arbitrator brought by or against Trustor or with respect to any
of the Mortgaged Property the basis of which is any Environmental Law.

                 (iii)  Trustor shall (or shall cause other parties obligated
to do so under contract or indemnity to) (A) take all commercially reasonable
actions to comply with any and all applicable present and future Environmental
Laws relating to the Chlor Alkali Plant; (B) pay in a timely fashion the cost
of any removal, response measure or corrective action relating to any Hazardous
Materials required by any Environmental Law or any order, regulation, consent
decree or similar agreement or instrument and keep the Mortgaged Property free
of any Lien imposed pursuant to any Environmental Law; (C) take all
commercially reasonable actions to not release, discharge or dispose of any
Hazardous Materials on, under or from the Mortgaged Property in violation of
any Environmental Law; (D) apply any insurance proceeds or other sums received
by it in respect of the removal of any Hazardous Material or any other
corrective action relating to any Hazardous Material to such removal or
corrective action; and (E) not take, or fail to take any action with respect to
any Environmental Laws or in connection with any Hazardous Materials that could
reasonably be expected to result in the incurrence of any obligation or
liability of any Secured Party.  During the continuance of an Event of Default,
in the event Trustor fails to comply with the covenants in the preceding
sentence, Beneficiary may (upon receipt of an indemnity satisfactory to
Beneficiary), in addition to any other remedies set forth herein, but shall not
be obligated to, as trustee for and at Trustor's sole cost and expense cause to
be taken, any remediation, removal, response or corrective action relating to
Hazardous Materials that is required by Environmental Law and is not being done
or contested by Trustor.  Any costs or expenses incurred by Beneficiary for
such purpose shall be immediately due and payable by Trustor and shall bear
interest at the Note Rate.  Trustor shall provide to Beneficiary and its agents
and employees access to the Mortgaged Property to take any action required by
Environmental Laws, or in





                                      -30-
   32
connection with any Hazardous Materials, that could be expected to result in
the incurrence of any obligation or liability of any Secured Party, if Trustor
fails to do so and such action or removal is required under any Environmental
Laws as provided above.  Upon written request by Beneficiary, which shall
include a reasonably specific statement of the basis thereof (which shall be
specific to the condition of the Mortgaged Property and the alleged violation
of Environmental Law) and which shall be made not more frequently than once in
any twelve-month period or at any time that Beneficiary is exercising its
remedies under this Deed of Trust, Beneficiary shall have the right (upon
receipt of an indemnity satisfactory to Beneficiary), but shall not be
obligated, at the sole cost and expense of Trustor, to conduct an environmental
audit or review of the Mortgaged Property relating to the specific items as
required in writing or relating to the remedy that Beneficiary is exercising
under this Deed of Trust by persons or firms appointed by Beneficiary, and
Trustor shall cooperate in all reasonable respects in the conduct of such
environmental audit or review, including, without limitation, by providing
reasonable access to the Mortgaged Property and to all records relating
thereto.  Such audit or review shall be conducted in a manner that would not
reasonably be expected to impose any additional material obligation upon, or
materially increase any obligation of, OCC Tacoma, Inc. or its successors
("OCC") under that certain Asset Purchase Agreement dated as of June 17, 1997
between OCC and Pioneer Companies, Inc., which





                                      -31-
   33
agreement was assigned by Pioneer Companies, Inc. to Trustor pursuant to the
Assignment and Assumption Agreement dated as of June 17, 1997, or any Related
Agreements (as defined in said Asset Purchase Agreement), with respect to
Hazardous Materials at the Mortgaged Property.  Trustor shall indemnify and
hold the Secured Parties harmless from and against all loss, cost, damage or
expense (including, without limitation, attorneys' fees) that any Secured Party
may sustain by reason of the assertion against such party of any claim relating
to such Hazardous Materials or actions taken with respect thereto as authorized
hereunder.  Nothing contained herein shall result in any Secured Party being
deemed an "owner" or "operator" under applicable Environmental Law.

                 (iv)  Trustor may at its own expense contest the amount or
applicability of any of the obligations described in the first sentence of
subsection IV(s)(iii) by appropriate legal proceedings, prosecution of which
operates to prevent the enforcement thereof; provided, however, that (A) any
such contest shall be conducted in good faith by appropriate legal proceedings
promptly instituted and diligently conducted and (B) in connection with such
contest, Trustor shall have made provision for the payment or performance of
such contested obligation on Trustor's books if and to the extent required by
generally accepted accounting principles then utilized by Trustor in the
preparation of its financial statements, or shall have deposited with
Beneficiary a sum sufficient to pay and discharge such obligation and
Beneficiary's estimate of all interest and penalties related thereto.
Notwithstanding the foregoing provisions of this subsection IV(s)(iv), no
contest of any such obligations may be pursued by Trustor if such contest would
expose the Deed of Trust Trustee, Beneficiary, or any other Secured Party to
any possible criminal liability or, unless Trustor shall have furnished an
Additional Undertaking (as hereinafter defined) therefor satisfactory to the
Deed of Trust Trustee, Beneficiary or such other Secured Party, as the case may
be, any civil liability for failure to comply with such obligations.

                 (t)  Asbestos.  Trustor shall not install nor permit to be
installed in the Mortgaged Property friable asbestos or any asbestos-containing
material (collectively, "ACM") except in





                                      -32-
   34
compliance with all applicable Environmental Laws respecting such material.
With respect to any ACM currently present in the Mortgaged Property, except
with respect to matters which would not have a Material Adverse Effect, Trustor
shall comply with all federal, state or local laws, regulations or orders
applicable to ACM located on the Chlor Alkali Plant, all at Trustor's sole cost
and expense.  If Trustor shall fail so to comply with such laws or regulations,
Beneficiary may (upon receipt of an indemnity satisfactory to Beneficiary)
during the continuance of an Event of Default, but shall not be obligated to,
in addition to any other remedies set forth herein, take those steps reasonably
necessary to comply with applicable law, regulations or orders.  Any costs or
expenses incurred by Beneficiary for such purpose shall be immediately due and
payable by Trustor and bear interest at the Note Rate.  Trustor shall provide
to Beneficiary and its agents and employees reasonable access to the Mortgaged
Property upon reasonable prior notice to remove such ACM if Trustor fails to do
so and removal is required under any Environmental Law as provided for above;
provided, however, that nothing contained herein shall obligate Beneficiary to
exercise any rights under such license.  Trustor shall indemnify and hold the
Secured Party harmless from and against all loss, cost, damage and expense that
any Secured Party may sustain as a result of the presence of any ACM and any
removal thereof in compliance with any applicable Environmental Law.

                 (u)  Books and Records; Reports.  Trustor shall keep proper
books of record and account, which shall accurately represent the financial
condition of Trustor and the business affairs of Trustor relating to the
Mortgaged Property.  Beneficiary and its authorized representatives shall have
the right, from time to time, upon reasonable prior notice to examine the books
and records of Trustor relating to the operation of the Mortgaged Property at
the office of Trustor.

                 (v)  No Claims Against Beneficiary.  Nothing contained in this
Deed of Trust shall constitute any consent or request by Beneficiary, express
or implied, for the performance of any labor or services or the furnishing





                                      -33-
   35
of any materials or other property in respect of the Chlor Alkali Plant or any
part thereof, nor as giving Trustor any right, power or authority to contract
for or permit the performance of any labor or services or the furnishing of any
materials or other property in such fashion as would permit the making of any
claim against Beneficiary in respect thereof or any claim that any Lien based
on the performance of such labor or services or the furnishing of any such
materials or other property is prior to the Lien of this Deed of Trust.

                 (w)  Utility Services.  Trustor shall pay, or cause to be
paid, when due all charges for all public or private utility services, all
public or private rail and highway services, all public or private
communication services, all sprinkler systems, and all protective services, any
other services of whatever kind or nature at any time rendered to or in
connection with the Chlor Alkali Plant or any part thereof, shall comply in all
material respects with all contracts relating to any such services, and shall
do all other things reasonably required for the maintenance and continuance of
all such services to the extent required to fulfill the obligations set forth
in subsection IV(n).

                 (x)  Notwithstanding any provisions herein to the contrary,
Trustor shall retain the right, at all times prior to foreclosure (or
deed-in-lieu thereof), to exercise custody and control with respect to actions
to be taken at the Mortgaged Property relating to the environmental condition
thereof, but only to the extent Trustor's exercise of such custody and control
of the Mortgaged Property is necessary for Trustor and/or its affiliates to
retain any and all benefits inuring to Trustor and/or its affiliates under the
indemnification provided by OCC in Article III of the Environmental Operating
Agreement dated as of June 17, 1997 between Trustor and OCC.

          SECTION V - ASSIGNMENT OF LEASES, RENTS, ISSUES AND PROFITS

                 (a)  Trustor absolutely, presently and irrevocably assigns,
transfers and sets over to Beneficiary and grants to Beneficiary, subject to
the terms and conditions hereof, all Trustor's estate, right, title and
interest (the "Trustor's Interest") in the Leases including, without
limitation, the following:

                 (i)  the immediate and continuing right to receive and collect
         Rents payable by all tenants or other parties pursuant to Leases;





                                      -34-
   36
             (ii)  all claims, rights, powers, privileges and remedies of
         Trustor, whether provided for in any Lease or arising by statute or at
         law or in equity or otherwise, consequent on any failure on the part
         of any tenant to perform or comply with any term of any Lease;

            (iii)  all rights to take all actions upon the happening of a
         default under any Lease as shall be permitted by such Lease or by law,
         including, without limitation, the commencement, conduct and
         consummation of proceedings at law or in equity; and

             (iv)  the full power and authority, in the name of Trustor or
         otherwise, to enforce, collect, receive and receipt for any and all of
         the foregoing and to do any and all other acts and things whatsoever
         which Trustor or any landlord is or may be entitled to do under the
         Leases.

                 (b)  Any Rents receivable by Beneficiary hereunder, after
payment of all proper costs and charges, shall be applied, in accordance with
the Intercreditor Agreement, to all amounts due and owing with respect to the
Secured Obligations.  Beneficiary shall be accountable to Trustor only for
Rents actually received by Beneficiary pursuant to this assignment.  The
collection of such Rents and the application thereof shall not cure or waive
any Event of Default or waive, modify or affect notice of an Event of Default
or invalidate any act done pursuant to such notice.

                 (c)  So long as no Event of Default shall have occurred and be
continuing, Trustor shall have a license to collect and apply the Rents and to
enforce the obligations of tenants under the Leases.  Immediately upon the
occurrence and during the continuance of any Event of Default, the license
granted in the immediately preceding sentence shall cease and terminate, with
or without any notice, action or proceeding.  Upon such Event of Default and
during the continuance thereof, Beneficiary may (but shall not be obligated to)
to the fullest extent permitted by the Leases (i) exercise any of Trustor's
rights under the Leases, (ii) enforce the Leases, (iii) demand, collect, sue
for, attach, levy, recover, receive, compromise and adjust, and make, execute
and deliver receipts and releases for all Rents or other payments





                                      -35-
   37
that may then be or may thereafter become due, owing or payable with respect to
the Leases and (iv) generally do, execute and perform any other act, deed,
matter or thing whatsoever that ought to be done, executed and performed in and
about or with respect to the Leases, as fully as allowed or authorized by the
Trustor's Interest.

                 (d)  During the continuance of an Event of Default, Trustor
hereby irrevocably authorizes and directs the tenant under each Lease to pay
directly to, or as directed by, Beneficiary all Rents accruing or due under its
Lease.  Trustor hereby authorizes the tenant under each Lease to rely upon and
comply with any notice or demand from Beneficiary for payment of Rents to
Beneficiary and Trustor shall have no claim against any tenant for Rents paid
by such tenant to Beneficiary pursuant to such notice or demand.

                 (e)  Trustor at its sole cost and expense shall enforce all
material provisions of the Leases in accordance with their terms.  Neither this
Deed of Trust nor any action or inaction on the part of Beneficiary shall
release any tenant under any Lease, any guarantor of any Lease or Trustor from
any of their respective obligations under the Leases or constitute an
assumption of any such obligation on the part of Beneficiary.  No action or
failure to act on the part of Trustor shall adversely affect or limit the
rights of Beneficiary under this Deed of Trust or, through this Deed of Trust,
under the Leases.

                 (f)  All rights, powers and privileges of Beneficiary herein
set forth are coupled with an interest and are irrevocable, subject to the
terms and conditions hereof, and Trustor shall not take any action under the
Leases or otherwise which is inconsistent with this Deed of Trust or any of the
terms hereof and any such action inconsistent herewith or therewith shall be
void.  Trustor shall, from time to time, upon request of Beneficiary, execute
all instruments and further assurances and all supplemental instruments and
take all such action as Beneficiary from time to time may reasonably request in
order to perfect, preserve and protect the interests intended to be assigned to
Beneficiary hereby.





                                      -36-
   38
                 (g)  Trustor shall not, unilaterally or by agreement,
subordinate, amend, modify, extend, discharge, terminate, surrender, waive or
otherwise change any term of any of the Leases in any manner which would
violate this Deed of Trust.  If the Leases shall be amended as permitted
hereby, they shall continue to be subject to the provisions hereof without the
necessity of any further act by any of the parties hereto.

                 (h)  Nothing contained herein shall operate or be construed to
(i) obligate the Deed of Trust Trustee or Beneficiary to perform any of the
terms, covenants or conditions contained in the Leases or otherwise to impose
any obligation upon the Deed of Trust Trustee or Beneficiary with respect to
the Leases (including, without limitation, any obligation arising out of any
covenant of quiet enjoyment contained in the Leases in the event that any
tenant under a Lease shall have been joined as a party defendant in any action
by which the estate of such tenant shall be terminated) or (ii) place upon the
Deed of Trust Trustee or Beneficiary any responsibility for the operation,
control, care, management or repair of any portion of the Mortgaged Property.

                 (i)  Beneficiary may also, at any time after an Event of
Default, apply to any court of competent jurisdiction for the appointment of a
receiver and Trustor agrees that such appointment shall be made upon a prima
facie showing of a claimed Event of Default without reference to any offsets or
defenses against such Event of Default.  Such receiver shall have all the
rights and powers provided to Beneficiary pursuant to this section or otherwise
provided hereunder or by law.  Said receiver may borrow monies and issue
certificates therefor.  Said certificates shall be a lien on the Mortgaged
Property subordinate only to this Deed of Trust and the Leases; provided,
however, that should any of said certificates be acquired by Beneficiary the
amount thereof shall constitute additional indebtedness secured hereby.  Such
receiver may lease all or any portion of the Mortgaged Property on such terms
and for such a term (which may extend beyond the terms of such receiver's
appointment and/or, if Beneficiary so consents, sale of the Mortgaged Property
hereunder) as such receiver may deem appropriate in its sole and absolute
discretion.  The entering upon and taking possession of the Mortgaged Property
pursuant to





                                      -37-
   39
this section and the collection of the Rents, issues and profits therefrom
shall not cure or waive any Event of Default or notice of an Event of Default
hereunder or invalidate any act of Beneficiary pursuant thereto.


                       SECTION VI - EVENTS OF DEFAULT

                 (a)  Events of Default.  As used in this Deed of Trust,
"Event of Default" shall mean the occurrence of an Event of Default under the
Indenture or the Term Loan Agreement or a breach or violation of the terms of
this Deed of Trust.

                 (b)  Remedies.  Upon the occurrence and during the continuance
of any Event of Default, in addition to any other rights and remedies
Beneficiary may have pursuant to this Deed of Trust or as provided by law, and
without limitation, Beneficiary may, subject to the terms of the Intercreditor
Agreement, declare all sums secured hereby immediately due and payable in full
and/or take such action, without notice or demand, as it deems advisable and is
permitted by law to protect and enforce its rights against Trustor and in and
to the Mortgaged Property, including, but not limited to, the following
actions, each of which may be pursued concurrently or otherwise, at such time
and in such manner as Beneficiary may determine, in its sole discretion,
without impairing or otherwise affecting the other rights and remedies of
Beneficiary, except to the extent otherwise provided by law:

                 (i)  (A)  Beneficiary shall have the right and option to
         foreclose this Deed of Trust judicially, in the same manner as a
         mortgage, or direct the Deed of Trust Trustee to sell the Mortgaged
         Property pursuant to the Deed of Trust Trustee's power of sale in
         accordance with the Washington Deed of Trust Act (RCW Ch. 61.24) and
         the procedures set forth below.  The procedure for exercise of the
         Deed of Trust Trustee's power of sale shall be as follows:

                 Upon written request therefor by Beneficiary specifying the
         nature of the default, or the nature of the several defaults, and the
         amount or amounts due and owing, the Deed of Trust Trustee shall
         execute a written notice of breach





                                      -38-
   40
         and of its election to cause the Mortgaged Property to be sold to
         satisfy the obligation secured hereby, and shall cause such notice to
         be recorded and otherwise given according to law.

                 Notice of sale having been given as then required by law and
         not less than the time then required by law having elapsed after
         recordation of such notice of breach, the Deed of Trust Trustee,
         without demand on Trustor, shall sell the Mortgaged Property at the
         time and place of sale specified in the notice, as provided by
         statute, either as a whole or in separate parcels and in such order as
         it may determine, at public auction to the highest and best bidder for
         cash in lawful money of the United States, payable at time of sale.
         Trustor agrees that such a sale (or a sheriff's sale pursuant to
         judicial foreclosure) of all the Mortgaged Property as real estate
         constitutes a commercially reasonable disposition thereof, but that
         with respect to all or any part of the Mortgaged Property which may be
         personal property the Deed of Trust Trustee shall have and exercise,
         at Beneficiary's sole election, all the rights and remedies of a
         secured party under the Uniform Commercial Code.  Whenever notice is
         permitted or required hereunder or under the Uniform Commercial Code,
         ten (10) days shall be deemed reasonable.  The Deed of Trust Trustee
         may postpone sale of all or any portion of the Mortgaged Property, and
         from time to time thereafter may postpone such sale, as provided by
         statute.  The Deed of Trust Trustee shall deliver to the purchaser its
         deed and bill of sale conveying the Mortgaged Property so sold, but
         without any covenant or warranty, express or implied.  The recital in
         such deed and bill of sale of any matters or facts shall be conclusive
         proof of the truthfulness thereof.  Any person other than the Deed of
         Trust Trustee, including Trustor or Beneficiary, may purchase at such
         sale.

                 After deducting all costs, fees and expenses of the Deed of
         Trust Trustee and of this trust, including the cost of evidence of
         title search and reasonable counsel fees in connection with sale, the
         Deed of Trust Trustee shall apply the proceeds of sale to payment of:
         all sums expended under the terms hereof not then repaid, with accrued
         interest at





                                      -39-
   41
         the Default Rate of interest specified in the Note; all other sums
         then secured hereby; and the remainder, if any, to the clerk of the
         superior court of the county in which the sale took place, as provided
         in RCW 61.24.080.

                 (B)  Trustor agrees to surrender possession of the hereinabove
         described Mortgaged Property to the purchaser at the aforesaid sale,
         immediately after such sale, in the event such possession has not
         previously been surrendered by Trustor.  Upon receipt of the sale
         price in the case of a third party purchase or upon the crediting of
         the applicable portion of the Secured Obligations to the sales price
         if the purchaser is Beneficiary, the Deed of Trust Trustee is hereby
         authorized, empowered and directed to make due conveyance to the
         purchaser or purchasers, with general warranty binding upon Trustor
         and the heirs, successors and assigns of Trustor.  The right of sale
         hereunder shall not be exhausted by one or more such sales, and the
         Deed of Trust Trustee may make other and successive sales until all of
         the Mortgaged Property be legally sold or all of the Secured
         Obligations shall have been paid.  Trustor hereby irrevocably appoints
         the Deed of Trust Trustee to be the attorney of Trustor and in the
         name and on behalf of Trustor to execute and deliver any deeds,
         transfers, conveyances, assignments, assurances and notices which
         Trustor ought to execute and deliver and do and perform any and all
         such acts and things which Trustor ought to do and perform under the
         covenants herein contained and generally, to use the name of Trustor
         in the exercise of all or any of the powers hereby conferred on the    
         Deed 




                                      -40-
   42
         of Trust Trustee.  Recitals contained in any conveyance made by the 
         Deed of Trust Trustee to any purchaser at any sale made pursuant hereto
         shall conclusively establish the truth and accuracy of the matters
         therein treated, including, without limiting the generality of the
         foregoing, nonpayment of the unpaid principal sum of, or the interest
         accrued on, any of the Secured Obligations after the same has become
         due and payable, advertisement and conduct of such sale in the manner
         provided herein and appointment of any successor trustee hereunder.
         The Deed of Trust Trustee or its successor or substitute may appoint
         or delegate any one or more persons as agent to perform any act or
         acts necessary or incident to any sale held by the Deed of Trust
         Trustee, including the posting of notices and the conduct of sale, but
         in the name and on behalf of the Deed of Trust Trustee, his successor
         or substitute.  If the Deed of Trust Trustee or his successor or
         substitute shall have given notice of sale hereunder, any successor or
         substitute Deed of Trust Trustee thereafter appointed may complete the
         sale and the conveyance of the property pursuant thereto as if such
         notice had been given by the successor or substitute Deed of Trust
         Trustee conducting the sale.

                 (ii)      (A)  Upon the occurrence and during the continuance
         of any Event of Default, the Deed of Trust Trustee or Beneficiary
         shall have the right and power to proceed by a suit or suits in equity
         or at law, whether for the specific performance of any covenant or
         agreement herein contained or in aid of the execution of any power
         herein granted, or for any foreclosure hereunder or for the sale of
         the Mortgaged Property under the judgment or decree of any court or
         courts of competent jurisdiction, or for the appointment of a receiver
         pending any foreclosure hereunder or the sale of the Mortgaged
         Property under the order of a court or courts of competent
         jurisdiction or under executory or other legal process, or for the
         enforcement of any other appropriate legal or equitable remedy.  Any
         money advanced by the Deed of Trust Trustee and/or Beneficiary in
         connection with any such receivership shall be a demand obligation
         (which obligation Trustor hereby expressly promises to pay) owing by
         Trustor to the Deed of Trust Trustee and/or Beneficiary and shall bear
         interest from the date of making such advance by the Deed of Trust
         Trustee and/or Beneficiary until paid at the Note Rate.

                 (B)  Trustor agrees to the full extent that it lawfully may,
         that, in case one or more of the Events of Default shall have occurred
         and shall not have been remedied, then, and in every such case, the
         Deed of Trust Trustee or Beneficiary shall have the right and power to
         enter into and upon and take possession of all or any part of the
         Mortgaged Property in the possession of Trustor, its successors or
         assigns, or its or their agents or servants, and may exclude Trustor,
         its successors or assigns, and all persons claiming under Trustor, and
         its or their agents or servants wholly or





                                      -41-
   43
         partly therefrom; and, holding the same, the Deed of Trust Trustee may
         use, administer, manage, operate and control the Mortgaged Property
         and conduct the business thereof to the same extent as Trustor, its
         successors or assigns, might at the time do and may exercise all
         rights and powers of Trustor, in the name, place and stead of Trustor,
         or otherwise as the Deed of Trust Trustee shall deem best.  All costs,
         expenses and liabilities of every character incurred by the Deed of
         Trust Trustee and/or Beneficiary in administering, managing,
         operating, and controlling the Mortgaged Property shall constitute a
         demand obligation (which obligation Trustor hereby expressly promises
         to pay) owing by Trustor to the Deed of Trust Trustee and/or
         Beneficiary and shall bear interest from date of expenditure until
         paid at the Note Rate, all of which shall constitute a portion of the
         Secured Obligations and shall be secured by this Deed of Trust and by
         any other instrument securing the Secured Obligations.  In connection
         with any action taken by the Deed of Trust Trustee and/or Beneficiary
         pursuant to this subsection (ii), the Deed of Trust Trustee and/or
         Beneficiary shall not be liable for any loss sustained by Trustor
         resulting from any act or omission of the Deed of Trust Trustee and/or
         Beneficiary in administering, managing, operating or controlling the
         Mortgaged Property, including a loss arising from the ordinary
         negligence of the Deed of Trust Trustee and/or Beneficiary, unless
         such loss is caused by its own gross negligence or willful misconduct
         and bad faith, nor shall the Deed of Trust Trustee and/or Beneficiary
         be obligated to perform or discharge any obligation, duty or liability
         of Trustor.

                 (C)  Trustor shall and does hereby agree to indemnify the Deed
         of Trust Trustee and/or Beneficiary for, and to hold the Deed of Trust
         Trustee and/or Beneficiary harmless from, any and all liability, loss
         or damage which may or might be incurred by the Deed of Trust Trustee
         and/or





                                      -42-
   44
         Beneficiary by reason of this Deed of Trust or the exercise of rights
         or remedies hereunder, including a loss arising from the ordinary
         negligence of the Deed of Trust Trustee and/or Beneficiary, except as
         such liability, loss or damage is occasioned by the gross negligence
         or willful misconduct of such party; should the Deed of Trust Trustee
         and/or Beneficiary make any expenditure on account of any such
         liability, loss or damage, the amount thereof, including costs,
         expenses and reasonable attorneys' fees, shall be a demand obligation
         (which obligation Trustor hereby expressly promises to pay) owing by
         Trustor to the Deed of Trust Trustee and/or Beneficiary and shall bear
         interest from the date expended until paid at the Note Rate, shall be
         a part of the Secured Obligations and shall be secured by this Deed of
         Trust and any other instrument securing the Secured Obligations.

                 (D)  Trustor hereby assents to, ratifies and confirms any and
         all actions of the Deed of Trust Trustee and/or Beneficiary with
         respect to the Mortgaged Property taken under this paragraph (ii).

                 (iii)  Every right, power and remedy herein given to the Deed
         of Trust Trustee and Beneficiary shall be cumulative and in addition
         to every other right, power and remedy herein specifically given or
         now or hereafter existing in equity, at law or by statute; and each
         and every right, power and remedy whether specifically herein given or
         otherwise existing may be exercised from time to time and so often and
         in such order as may be deemed expedient by the Deed of Trust Trustee
         and Beneficiary, and the exercise, or the beginning of the exercise,
         of any such right, power or remedy shall not be deemed a waiver of the
         right to exercise, at the same time or thereafter any other right,
         power or remedy.  No delay or omission by the Deed of Trust Trustee or
         Beneficiary in the exercise of any right, power or remedy shall impair
         any such right, power or remedy or operate as a waiver thereof or of
         any other right, power or remedy then or thereafter existing.

                 (iv)  To the extent permitted under applicable law,
         Beneficiary shall have the right (but shall not be obligated to) to
         become the purchaser at any sale held by the Deed of Trust Trustee or
         by any receiver or public officer, whether by power of sale, judicial
         procedure or otherwise, and shall have the right (but shall not be
         obligated to) to have all or any part of the Secured Obligations then
         owing credited





                                      -43-
   45
         against the amount of the bid made by Beneficiary at such sale.

                 (v)  Upon any sale, whether under the power of sale hereby
         given or by virtue of judicial proceedings, it shall not be necessary
         for the Deed of Trust Trustee or any public officer acting under
         execution or order of court to have physically present or
         constructively in his or her possession any of the Mortgaged Property,
         and Trustor hereby agrees to deliver all of such personal property to
         the purchasers at such sale on the date of sale, and if it should be
         impossible or impracticable to make actual delivery of such property,
         then the title and right of possession to such property shall pass to
         the purchaser at such sale as completely as if such property had been
         actually present and delivered.

                 (vi)  Upon any sale, whether made under the power of sale
         hereby given or by virtue of judicial proceedings, the receipt of the
         Deed of Trust Trustee, or of the officer making a sale under judicial
         proceedings, shall be a sufficient discharge to the purchaser or
         purchasers at any sale for his or her or their purchase money, and
         such purchaser or purchasers, his or her or their assigns or personal
         representatives, shall not, after paying such purchase money and
         receiving such receipt of the Deed of Trust Trustee or of such officer
         therefor, be obliged to see to the application of such purchase money,
         or be in anywise answerable for any loss, misapplication or
         nonapplication thereof.

                 (vii)  (A)  Any sale or sales of the Mortgaged Property or any
         part thereof, whether under the power of sale herein granted and
         conferred or under and by virtue of judicial proceedings, shall
         operate to divest all right, title, interest, claim and demand
         whatsoever, either at law or in equity, of Trustor of, in and to the
         premises and the property sold, and shall be a perpetual bar, both at
         law and in equity, against Trustor, its successors and assigns, and
         against any and all persons claiming or who shall thereafter claim all
         or any of the property sold from, through or under Trustor, its
         successors and assigns; and Trustor, if





                                      -44-
   46
         requested by the Deed of Trust Trustee or Beneficiary to do so, shall
         join in the execution and delivery of all proper conveyances,
         assignments and transfers of the properties so sold.

                 (B)  The proceeds of any sale of the Mortgaged Property or any
         part thereof and all other moneys received by the Deed of Trust
         Trustee in any proceedings for the enforcement hereof, whose
         application has not elsewhere herein been specifically provided for,
         shall be applied first, to the payment of all expenses incurred by the
         Deed of Trust Trustee or Beneficiary incident to the enforcement of
         this Deed of Trust or any of the Secured Obligations (including,
         without limiting the generality of the foregoing, expenses of any
         entry or taking of possession, of any sale, of advertisement thereof,
         and of conveyances, and court costs, compensation of agents and
         employees and reasonable legal fees), and to the payment of all other
         charges, expenses, liabilities and advances incurred or made by the
         Deed of Trust Trustee or Beneficiary under this Deed of Trust or in
         executing any trust or power hereunder; and then to the payment of the
         Secured Obligations in such order and manner as is determined by
         Beneficiary in its sole discretion, subject to the terms of the
         Intercreditor Agreement.

                 (C)  Beneficiary may resort to any security given by this Deed
         of Trust or to any other security now existing or hereafter given to
         secure the payment of any of the Secured Obligations secured hereby,
         in whole or in part, and in such portions and in such order as may
         seem best to Beneficiary in its sole discretion, subject to the terms
         of the Intercreditor Agreement, and any such action shall not in
         anywise be considered as a waiver of any of the rights, benefits or
         liens created by this Deed of Trust.

                 (D)  Trustor agrees, to the full extent that it may lawfully
         so agree, that it will not at any time insist upon or plead or in any
         manner whatever claim or take the benefit or advantage of any
         appraisement, valuation, stay, extension or redemption law now or
         hereafter in force, in order to prevent or hinder the enforcement or
         foreclosure of this Deed of Trust or the absolute sale of the
         Mortgaged Property





                                      -45-
   47
         or the possession thereof by any purchaser at any sale made pursuant
         to any provision hereof, or pursuant to the decree of any court of
         competent jurisdiction; but Trustor, for itself and all who may claim

         hereof, and agrees that any court having jurisdiction to foreclose

         referred to herein and now in force, of which Trustor or its successor
         or successors might take advantage despite the provisions hereof,
         shall hereafter be repealed or cease to be in force, such law shall
         not thereafter be deemed to constitute any part of the contract herein
         contained or to preclude the operation or application of the
         provisions hereof.

                 (E)  If the proceeds of any sale or other lawful disposition
         of the Mortgaged Property by the Deed of Trust Trustee and/or
         Beneficiary are insufficient to pay the Secured Obligations, then
         Trustor shall pay or cause to be paid any deficiency.

                 (viii)  Without in any manner limiting the generality of any
         of the other provisions of this Deed of Trust; (A) some portions of
         the goods described or to which reference is made herein are or are to
         become fixtures on the land described or to which reference is made
         herein; (B) the security interests created hereby under the Uniform
         Commercial Code will attach to minerals including oil and gas; (C)
         this instrument is to be filed of record in the real estate records as
         a financing statement; and (D) Trustor is the record owner of the real
         estate or interests in the real estate comprised of the Mortgaged
         Property.

                 (ix)  The Mortgaged Property may be sold in one or more
         parcels and in such manner and order as Beneficiary, in its sole
         discretion, may determine.

                 Beneficiary's exercise of the foregoing remedies will not be
construed to constitute Beneficiary as a mortgagee in possession of the
Mortgaged Property nor to obligate Beneficiary to take any action or to incur
expenses or perform or discharge any obligation, duty or liability of Trustor
under any lease, or for the control, care, management, or repair of the
Mortgaged Property; nor will it operate to make Beneficiary responsible or
liable for any waste committed on the Mortgaged Property by any Person or for
any dangerous or defective condition of the Mortgaged Property, or for any act
or omission relating to the management, upkeep, repair, or control of the
Mortgaged Property that results in loss or injury or death to any Person.

notice thereof, or to see to the payment of or be under any duty in respect of
any tax or assessment or other governmental charge which may be levied or
assessed on the Mortgaged Property, or any part thereof, or against Trustor, or

agreements contained herein.  The Deed of Trust Trustee shall not be
responsible for the execution, acknowledgment or validity of this Deed of Trust
or of any instrument in addition or supplemental hereto or for the sufficiency
of the security purported to be created hereby, and makes no representation in

Trustee shall have the right to consult with counsel upon any matters arising
hereunder and shall be fully protected in relying as to legal matters on the
