ARTICLE V
PRICE

SECTION 5.1 Price of Chlorine. Each calendar quarter during the Term,

each calendar quarter during the Term (other than the initial calendar quarter),
OCC Tacoma shall provide to Pioneer a written notification of the Price
applicable to chlorine during the preceding calendar quarter and which shall be

calendar quarter pursuant to this Agreement. At all times during the Term,
Pioneer shall take such measures, and implement and utilize such procedures, as
will ensure that access to the Price applicable to chlorine sold to OCC Tacoma
pursuant to this Agreement (i) will be limited to employees of Pioneer who have
a need to know such information for the purpose of discharging Pioneer's
financial and accounting obligations, and (ii) will not be provided to (A) any
personnel of Pioneer or any of its Affiliates who exercise any pricing, sales or

non-use shall not apply to any information that (i) was in the public domain at
the time of disclosure by OxyChem or any of its Affiliates to Pioneer; (ii)
enters the public domain through no fault of Pioneer; (iii) was communicated to
Pioneer by any other Person free of any obligation of confidence; or (iv) was
developed by officers, employees or agents of or consultants to Pioneer
independently of and without reference to the proprietary information of
OxyChem. The Price of chlorine sold hereunder, shall not be deemed to be within
the public domain, or communicated free of any obligation of confidence, for
purposes of the provisions of this paragraph simply because it is known by the
U.S. Gulf Coast contract customers of OCC Tacoma or OxyChem.

12
(c) The Price of chlorine which shall be in effect for the initial
calendar quarter, or portion thereof if this Agreement is not effective as of
the first day of the initial calendar quarter, shall be determined as provided
in Section 5.1 above, using the Price applicable to chlorine during the
calendar quarter immediately preceding the calendar quarter in which this
Agreement shall become effective.

(d) Pioneer shall invoice OCC Tacoma on the date of shipment for
each shipment of chlorine delivered during the preceding month at the Price
specified by OCC Tacoma as applicable during such period pursuant to this
Article V. Payment terms for Pioneer's invoice shall be net thirty (30) days
from the date of the invoice with OCC Tacoma to pay interest (not to exceed the
maximum lawful rate) on any amounts past due in accordance with Pioneer's
standard terms and conditions for like customers, a copy of which is attached
as Appendix C to this Agreement. Shipments made in a calendar quarter prior to
OCC Tacoma's notification of Price pursuant to Section 5.2(a) shall be invoiced
at the Price applicable to shipments during the prior calendar quarter. Within
five (5) days after receipt of such notice from OCC Tacoma, Pioneer shall send
a statement to OCC Tacoma reflecting any adjustments to invoices which are
necessary to conform to the Price for the then current quarter. All amounts
due as shown by such statement shall be reflected in Pioneer's invoices for next
succeeding shipments hereunder.

SECTION 5.3 Pioneer's Right to Audit. Within sixty (60) days
following any quarterly notification by OCC Tacoma of the Price pursuant to the
provisions of Section 5.2, and upon not less than fifteen (15) days' notice in
advance by Pioneer, OCC Tacoma shall permit, and shall cause OxyChem to permit,
the Oxy Accountant to have access to and examine OCC Tacoma's and OxyChem's
books and records sufficient to permit the verification of the calculation of
the Price of chlorine in effect during such calendar quarter. The Oxy
Accountant shall report to Pioneer its conclusion concerning the accuracy of
OCC Tacoma's calculations of the foregoing items, and, if inaccurate, what the
Oxy Accountant considers to be a correct adjustment. OxyChem shall instruct
the Oxy Accountant not to disclose any additional information to Pioneer. The
reasonable cost of such audit shall be borne by Pioneer, provided, however,
that, if any such audit results in a finding that an adjustment of more than
one percent (1%) to the Price of chlorine is required to comply with the
provisions of Section 5.1, then the cost of such audit shall be borne by OCC
Tacoma.

ARTICLE VI

the Initial Year and the two consecutive years after the Initial Year, in
addition to the Price for such chlorine, OCC Tacoma shall be responsible for
the actual freight cost incurred in shipping such chlorine from the Tacoma
Plant, or such other shipping point as the Parties may agree, to the designated
Delivery Points. OCC Tacoma may, at its sole option, and upon five business
days' prior notice, elect (i) to require Pioneer to ship chlorine on a freight
prepaid and collect basis, or (ii) to arrange directly with a provider of

provider and Pioneer shall have no liability for such costs.

(b) For each shipment of chlorine pursuant to this Agreement during
the fourth and fifth years of the Term, in addition to the Price for such
chlorine, OCC Tacoma shall be responsible for fifty percent (50%) of the actual
freight cost incurred in shipping such chlorine from the Tacoma Plant, or such
other shipping point as the Parties may agree, to the designated Delivery
Points and Pioneer shall be responsible for the remaining fifty percent (50%)
of such freight cost. OCC Tacoma may, at its sole option, and upon five
business days' prior notice, elect (i) to require Pioneer to ship chlorine on a
freight prepaid and collect basis, or (ii) to arrange directly with a provider
of transportation services for the shipment of such chlorine. In the case of
clause (i) above, fifty percent (50%) of the freight costs shall be added to
Pioneer's invoice for chlorine and such invoice shall be paid by OCC Tacoma as
provided in Section 5.2. In the case of

8
14
clause (ii) above, OCC Tacoma shall be responsible to pay the applicable
transportation charges directly to the transportation service provider and

against Pioneer's invoice with respect to such chlorine.

(c) OCC Tacoma shall pay any applicable rail car demurrage charges in
accordance with Pioneer's standard terms and conditions, attached as Appendix C
to this Agreement.

(d) Pioneer and OCC Tacoma shall cooperate in exercising reasonable
commercial efforts to reduce net transportation costs on shipments of chlorine
pursuant to this Agreement.

(e) Regardless of the manner in which freight costs are allocated in
this Agreement, all chlorine sold by Pioneer pursuant to this Agreement shall
be delivered in rail cars owned or leased by Pioneer. OCC Tacoma shall have no
responsibility to provide or otherwise to make rail cars available to Pioneer
for the shipment of chlorine pursuant to this Agreement, nor, except as
otherwise provided in this Agreement, for any cost or expense in connection
therewith.

SECTION 6.4 OCC Tacoma's Right to Audit Certain Transportation
Charges. Within sixty (60) days following the receipt of any invoice from
Pioneer which includes transportation charges to be reimbursed by OCC Tacoma
pursuant to Section 6.3(a)(i) or Section 6.3(b)(i), and upon not less than
fifteen (15) days' prior notice by OxyChem, Pioneer shall permit the Pioneer
Accountant to have access to and examine Pioneer's books and records sufficient
to permit the verification of the transportation charges reflected on such
invoice. The Pioneer Accountant shall report to OCC Tacoma its conclusion
concerning the accuracy of Pioneer's invoice in respect of such transportation
charges, and, if inaccurate, what the Pioneer Accountant considers to be a
correct adjustment. Pioneer shall instruct the Pioneer Accountant not to
disclose any additional information to OCC Tacoma. The reasonable cost of such
audit shall be borne by OCC Tacoma, provided, however, that if any such audit
results in a finding that an adjustment of more than one percent (1%) to the
invoice in respect of such transportation charges is required to comply with the
provisions of Section 6.3, then the cost of such audit shall be borne by
Pioneer.

ARTICLE VII
MEASUREMENT

SECTION 7.1 Rail Car Delivery.

(a) If chlorine is delivered in rail tank cars loaded at the Tacoma
Plant, the quantity of chlorine shall be determined by rail tank car weigh
scales or other mutually agreed measuring device which shall be operated,
maintained and regularly calibrated by Pioneer in accordance with accepted
industry practice. Pioneer's weights and measures shall govern except in case
of demonstrated error.

(b) If chlorine is delivered in rail tank cars loaded by a third
party, the quantity of chlorine so delivered shall be determined by rail tank
car weigh scales or other measuring device

9
15

employed in connection with the loading of such rail cars in accordance with
accepted industry practice. Third party weights and measures shall govern
except in case of demonstrated error.

SECTION 7.2 Calibration of Measuring Devices.

(a) In respect of any chlorine delivered hereunder the quantity of
which is measured by devices operated by Pioneer, Pioneer shall give OCC Tacoma
at least three (3) days' prior notice of any calibration test to be performed
on any such device, and OCC Tacoma may elect to have a representative present
at any such test. If a level of inaccuracy is determined by such test at plus or
minus one percent (1%) or more of full scale, Pioneer shall restore the
measuring device to a condition of accuracy, and billings shall be corrected
for any shipment(s) known to be affected by such inaccuracy.

(b) In respect of any chlorine delivered hereunder the quantity of
which is measured by devices operated by a third party, Pioneer shall exercise
reasonable commercial efforts to afford to OCC Tacoma (i) at least (3) days'
prior notice of any calibration test (of which Pioneer has advance knowledge)
to be performed on any such device, and (ii) an opportunity for OCC Tacoma to
have a representative present at any such test. If a level of inaccuracy is
determined by such test at plus or minus one percent (1%) or more of full
scale, Pioneer's billings to OCC Tacoma shall be corrected for any shipment(s)
known to be affected by such inaccuracy.

capital, net taxable earned surplus, or asset value, and (ii) any taxes (and
any interest, additions to tax or penalties imposed in connection therewith)
imposed on or in respect of equipment used to produce or transport chlorine)

Pioneer furnishes to OCC Tacoma satisfactory written evidence of the amount and

(a) Except to the extent caused by any breach of OCC Tacoma's
obligations hereunder, any act or omission of OCC Tacoma, its agents or
contractors, or any condition, event or action occurring after the time the tank
car is constructively or actually placed at the Delivery Point ("Delivery Time")
which is caused by any Person other than Pioneer, Pioneer assumes full
responsibility for any liability arising out of the manufacture, handling,
storage, loading, transportation and, to the extent attributable to any defect
in the vehicle or vessel used to deliver chlorine, the unloading of any chlorine
sold hereunder and compliance or non-compliance with any law or regulations
relating thereto, including, without limitation, laws or regulations with
respect to the protection of health, safety and the environment. With respect to
matters for which Pioneer is liable under the preceding sentence, Pioneer shall
defend, indemnify and hold harmless OCC Tacoma, its Affiliates, and their
respective officers, directors, representatives and employees from and against
all losses, liabilities, damages and expenses ("Losses") made against or
incurred by OCC Tacoma, its Affiliates, or their respective officers, directors,
representatives and employees arising out of any claim, suit or proceeding
("Claim") by any governmental agency or any third party which alleges death,
personal or economic injury, or damages to, or spills or releases on or into,
any private or public property, resources or the environment, to the extent
caused or contributed to by chlorine sold hereunder.

(b) Except to the extent caused by any breach of Pioneer's
obligations hereunder, any act or omission of Pioneer, its agents or
contractors, or any condition, event or action occurring prior to the Delivery
Time which is caused by any Person other than OCC Tacoma, OCC Tacoma assumes
full responsibility for any liability arising out of the handling, storage and
unloading of any chlorine sold hereunder and compliance or non-compliance with
any law or regulations relating thereto, including, without limitation, laws or
regulations with respect to the protection of health, safety and the
environment, provided, however, that OCC Tacoma shall have no responsibility for
any liability arising out of the unloading of any chlorine sold hereunder which
is attributable to any defect in the vehicle or vessel used to deliver such
chlorine. With respect to matters for which OCC Tacoma is liable under the
preceding sentence, OCC Tacoma shall defend, indemnify and hold harmless
Pioneer, its Affiliates, and their respective officers, directors,
representatives and employees from and against all Losses made against or
incurred by Pioneer, its Affiliates, or their respective officers, directors,
representatives and employees arising out of any Claim by any governmental
agency or any third party which alleges death, personal or economic injury, or
damages to, or spills or releases on or into, any private or public property,
resources or the environment, to the extent caused or contributed to by
chlorine sold hereunder.

(c) Neither Party shall be liable for claims of the employees,
contractors or agents of the other Party who are subject to workers'
compensation laws. Notwithstanding anything to the contrary herein, neither
Party shall be responsible for protection of the employees, agents or

12
18
contractors of the other Party or liable for any failure to provide such
protection, including, without limitation, compliance with occupational safety

SECTION 10.2 Procedures for Indemnification.

(a) Promptly (and in any event within thirty (30) days) after a
Party or Parties to be indemnified (whether one or more, the "Indemnified
Party") receives notice of any Claim covered by Section 10.1, the Indemnified
Party shall, if a Claim in respect thereof is to be made pursuant to Section
10.1, notify the Party from whom indemnification is sought (the "Indemnifying
Party") in writing of such Claim; provided, however, that the failure to so
notify the Indemnifying Party shall not relieve the Indemnifying Party from any
liability which it may have to the Indemnified Party pursuant to Section
10.1, except to the extent of any material detriment suffered by the
Indemnifying Party as a result of such failure. The amount of each Claim for
indemnity, together with a list identifying each separate item of Loss to the
extent known, shall be set forth in the Claim notice delivered to the
Indemnifying Party. In the event that a Claim arises out of, or results from,
Claims of third parties, the Indemnifying Party may at its option undertake the
defense thereof by counsel or representatives chosen by it which are reasonably
acceptable to the Indemnified party. The Indemnifying Party shall have the sole
right to compromise or settle any such Claim if (i) such settlement or
disposition shall impose no material obligation or burden whatsoever on the
Indemnified Party which is not wholly discharged by the Indemnifying Party and
shall provide a full release to the Indemnified Party, and (ii) the
Indemnifying Party shall be fully capable of performing its obligations
pursuant to such settlement or disposition. Each of the Indemnifying Party and
the Indemnified Party shall be entitled to consult with each other, to the
extent it reasonably requests, in respect of the defense of such Claim and shall
cooperate in the defense of any such Claim, including making its officers,
directors, employees and books and records available for use in defending
against such Claim, and it shall take those commercially reasonable actions
within it power which are necessary to preserve any legal defenses to such
matters.

(b) If the Indemnifying Party, within a reasonable time after
notice of any third party Claim, fails to undertake the defense of such Claim,
the Indemnified Party will, by notice to the Indemnifying Party of its intent
to do so, have the right to undertake the defense of such Claim with counsel or
representatives chosen by it which are reasonably acceptable to the Indemnifying
Party. The Losses of the Indemnified Party shall include the reasonable costs
and expenses incurred in any such defense of a third party's Claim.
Notwithstanding the foregoing, the Indemnified Party shall have no right to
settle or compromise any such Claim without the prior written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.

ARTICLE XI

EXCUSE OF PERFORMANCE

SECTION 11.1 Excuse of Performance.

(a) Performance of any obligation under this Agreement may be
suspended by either Party without liability, to the extent that: an Act of God;
war; riot; fire; explosion; accident; flood; sabotage; mechanical breakdown;
involuntary plant shutdown; governmental laws, regulations or orders; or any
other cause (except financial) beyond the reasonable control of such Party; or
any labor trouble, strike, walkout, lockout or injunction (whether or not such
labor event is within the reasonable control of such Party), delays, prevents,
restricts, or limits the performance of, this Agreement or the consumption,
sale or use of chlorine, provided however, that if any of the foregoing events
shall delay, prevent, restrict or limit OCC Tacoma's ability to receive
chlorine at Ingleside, Texas, then for the first thirty days of any such period
of suspension, OCC Tacoma shall not be relieved of its obligations under this
Agreement to the extent that no such event delays, prevents, restricts or
limits the ability of OCC Tacoma or any of its Affiliates to receive chlorine
at any other State of Texas or Gulf Coast delivery point. The affected Party
may invoke this provision by promptly notifying the other Party in writing of
the nature and estimated duration of the suspension period and shall exercise
all reasonable diligence in curing such condition.

(b) In the event that either Party exercises its right to suspend
performance hereunder, the Term of this Agreement and the obligations of the
Parties to purchase and sell chlorine hereunder allocable to such period that
performance is suspended shall be extended one day for each day of such
suspension provided that the suspension shall not exceed 30 days. In the event
that such suspension is great than 30 days but less than 180 days, this
Agreement shall remain in effect with the obligations of the Parties to
purchase and sell chlorine hereunder suspended and an amount of chlorine
determined by multiplying the annual volume of chlorine to be delivered and
received in the year in which the suspension of performance occurs (as fixed
pursuant to Section 3.3) by a fraction, the numerator of which is the number of
days in which performance is suspended (less thirty days in the case of OCC
Tacoma) and the denominator of which is 365, deducted from the obligations
contained herein to purchase and sell. If any such suspension lasts more than
180 days, the Party as to whom performance of its obligations under this
Agreement has not been suspended may terminate this Agreement by providing the
other Party written notice of its intent to terminate.

ARTICLE XII

DEFAULT AND REMEDIES

SECTION 12.1 Default and Remedies.

(a) In the event that: (i) OCC Tacoma shall fail to pay any invoice
in accordance with the terms of this Agreement, (ii) any Party shall fail, in
any material respect, in the due

14
20

performance or observance by it of any of the terms, covenants or agreements
contained in this Agreement, or (iii) any Party shall become or be adjudicated
insolvent, bankrupt, or if a receiver or trustee shall be appointed for any
Party or its property or a petition for reorganization or arrangement under any
bankruptcy or insolvency law shall be approved, or an assignment shall be made
for the benefit of creditors of any Party, or any Party shall file a voluntary
petition in bankruptcy or shall consent to the appointment of a receiver or
trustee, this Agreement shall, in the case of a default under clause (iii),
immediately terminate, and in the case of a default under clause (i) or (ii),
the non-defaulting Party shall have the right, at its sole discretion, to
terminate this Agreement if the defaulting Party shall have failed to (A) cure
the default within twenty (20) days of written notice of default, or (B) except
in the case of a default under clause (i), diligently pursue the curing of the
default, which termination remedy shall be in addition to all of its remedies at
law or in equity, including, without limitation, those set forth in Section
12.1(b), to recover damages by reason of such default. In the event of any such
termination, all sums then owing by any Party under this Agreement shall become
and be immediately due and payable, without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived by the Parties.

(b) The Parties agree that the covenants and obligations contained
in this Agreement relate to special, unique and extraordinary matters and that
a violation of any of the terms hereof would cause irreparable injury in an
amount which would be difficult or impossible to estimate or determine and for
which any remedy at law would be inadequate. As such, the Parties agree that if
either Party fails or refuses to fulfill any of its obligations under this
Agreement or to make any payment hereunder, then the other Party shall have the
remedy of specific performance, which remedy shall be cumulative and
nonexclusive and shall be in addition to any other rights and remedies
otherwise available at law or in equity and to which such Party might be
entitled.

SECTION 12.2 Certain Damages Excluded. In no event shall either
Party to this Agreement, or its Affiliates, have any liability to the other
Party, or its Affiliates, for any (i) loss of business opportunities or for
speculative or prospective profits, or (ii) special, indirect, consequential,
incidental or punitive damages, provided, however, that in the event of any
breach or failure by OCC Tacoma to take and purchase the quantities of chlorine
provided for hereunder, Pioneer shall be entitled to recover the difference, if
any, between amounts realized from any sale in mitigation of damages resulting
form such breach or failure in performance by OCC Tacoma and the amount that
would have been realized by Pioneer but for such breach or failure in
performance by OCC Tacoma, plus freight costs actually incurred by Pioneer and
which otherwise would have been payable by OCC Tacoma pursuant to the
provisions of this Agreement.

SECTION 12.3 Duty to Mitigate. Each Party shall take all such
reasonable actions as may be necessary to mitigate damages for which such Party
may claim damages or indemnification under this Agreement, provided, however,
that in no event shall Pioneer be obligated to sell and deliver chlorine
committed for but not taken and purchased by OCC Tacoma to other than delivery
points east of the Rocky Mountains.

ARTICLE XIII

MISCELLANEOUS

SECTION 13.1 Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the Parties and their respective
successors and permitted assigns, but neither this Agreement nor any of the
rights, interests or obligations hereunder shall be assigned, by operation of
law or otherwise (other than as a result of any merger or consolidation), by
any Party without the prior express written consent of the other Party;
provided, however, that, notwithstanding the foregoing, (i), in connection with
the sale of the Tacoma Plant as a whole, or any sale of the properties and
assets of any Party substantially as an entirety, to any Person, the Party
making such sale may assign this Agreement, or its rights hereunder, to such
Person, (ii) any Party may assign this Agreement, or its rights hereunder, to
any Affiliate of such Party, and (iii) Pioneer shall have the right to
collaterally assign its rights under this Agreement to any bank, financial
institution or other lender (or any such entity acting as an indenture trustee
on behalf of any Person) that provides financing in connection with (x) the
transactions contemplated by the Asset Purchase Agreement or any Related
Agreement (including any renewal, extension or rearrangement of such financing)
or (y) working capital financing for Facility Operations, provided, however,
that no such collateral assignment shall release, discharge or otherwise excuse
Pioneer from the performance of its obligations under this Agreement; provided,
further, that (A), in the case of any assignment referred to in clause (i) or
(ii) of this Section 13.1, prior to any such assignment, the Person to which
such assignment shall be made shall expressly assume, by an instrument in
writing reasonably satisfactory to OCC Tacoma or Pioneer, as the case may be,
executed and delivered to OCC Tacoma or Pioneer, as the case may be, the
performance and observance of every obligation, covenant and agreement in this
Agreement on the part of the Party making such assignment to be performed or

Party on any other Person (including any such additional Party) from its

sought to be enforced. No waiver by any Party of any default,
misrepresentation or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any such occurrence. Neither
the failure nor any delay by any Party in exercising any right, power or
privilege under this Agreement will operate as a waiver of such right, power or
privilege, and no single or partial exercise of any such right, power or
privilege will preclude any further or other exercise of such right, power or
privilege or the exercise of any other right, power or privilege.

Parties agree that any court proceedings arising out of this Agreement may be

Parties consent to the jurisdiction of such courts. Each Party irrevocably
waives (a) any objection which such Party may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of, or relating
to, this Agreement brought in any such court, (b) any claim that any such suit,
action or proceeding brought in any such court has been brought in an
inconvenient forum, and (c) the right to object, with respect to any such
claim, suit, action or proceeding brought in any such court, that such court
does not have jurisdiction over such Party. In addition, any such suit, action
or proceeding may be brought in any court having jurisdiction pursuant to the
