submitted to it, the Neutral Firm shall deliver to Phillips and Chevron its
determination of the Actual Net Working Capital and/or Actual Contributed Cash,
which determination shall be final and binding on the Parties and then shall be
deemed such Party's Actual Net Working Capital and/or Actual Contributed Cash.
The fees and expenses of the Neutral Firm shall be allocated between Phillips
and Chevron by the Neutral Firm.

            (d) After a determination of either Party's Contributed Cash shall
have become final and binding on Phillips and Chevron as described in Section
3.3(c), the Company shall pay to such Party an amount equal to the Actual
Contributed Cash of such Party.

            (e) After a determination of both Parties' Actual Net Working
Capital shall have become final and binding on Phillips and Chevron as described
in Section 3.3(c):

               (i)   if both of the C Chem Working Capital Difference and the P
     Chem Working Capital Difference are greater than or equal to zero, then the
     absolute difference between the C Chem Working Capital Difference and the P
     Chem Working Capital Difference shall be a loan to the Company and the
     Company shall pay such difference either to Chevron, if the C Chem Working
     Capital Difference is greater than the P Chem Working Capital Difference,
     or to Phillips, if the P Chem Working Capital Difference is greater than
     the C Chem Working Capital Difference;

               (ii)  if both of the C Chem Working Capital Difference and the P
     Chem Working Capital Difference are less than zero, then the absolute
     difference between the C Chem Working Capital Difference and the P Chem
     Working Capital Difference shall be a loan to the Company and the Company
     shall pay such difference either to Chevron, if the C Chem Working Capital
     Difference is closer to zero than the P Chem Working Capital Difference, or
     to Phillips, if the P Chem Working Capital Difference is closer to zero
     than the C Chem Working Capital Difference;

               (iii) if the C Chem Working Capital Difference is greater than
     or equal to zero and the P Chem Working Capital Difference is less than
     zero, then the sum of the C Chem Working Capital Difference and the
     absolute value of the P Chem Working Capital Difference shall be a loan to
     the Company and the Company shall pay such sum to Chevron; or

               (iv)  if the P Chem Working Capital Difference is greater than
     or equal to zero and the C Chem Working Capital Difference is less than
     zero, then the sum of the P Chem Working Capital Difference and the
     absolute value of the C Chem Working Capital Difference shall be a loan to
     the Company and the Company shall pay such sum to Phillips.

                                   ARTICLE IV

                   REPRESENTATIONS AND WARRANTIES OF PHILLIPS

            Phillips hereby represents and warrants to each of Chevron and the
Company that, except as disclosed on the Phillips Disclosure Schedule (PROVIDED
that, as used in this Article IV only, unless the context otherwise requires,
all references to Phillips (and/or its Affiliates) shall be deemed to refer to
Phillips and all of the Subsidiaries of Phillips, but in each case, only with
respect to the businesses of P Chem):

            Section 4.1 Corporate Organization. Phillips and the P Chem
Subsidiaries are duly organized, validly existing and in good standing under the
laws of their respective jurisdictions of incorporation or organization. Each of
Phillips and each P Chem Subsidiary has all requisite corporate power and
authority to own or lease all of its properties and assets and to carry on its
businesses as it is now being conducted, and is duly licensed or qualified to do
business in each jurisdiction in which the nature of the businesses conducted by
it or the character or location of the properties and assets owned or leased by
it makes such licensing or qualification necessary, except where the failure to
be so licensed or qualified would not have, individually or in the aggregate, a
Material Adverse Effect on either Phillips or P Chem, as applicable. True and
complete copies of the certificate of incorporation and by-laws or comparable
organizational documents of each P Chem Subsidiary, in effect as of the date of
this Agreement, have previously been made available by Phillips to Chevron.

            Section 4.2 Capitalization. Schedule 4.2 of the Phillips Disclosure
Schedule sets forth a complete list of all of the P Chem Subsidiaries and their
respective jurisdictions of organization and capitalization as of the date
hereof. All of the outstanding shares of capital stock or outstanding limited
liability company interests of each P Chem Subsidiary are validly issued, fully
paid and nonassessable, and, except as set forth on Schedule 4.2 of the Phillips
Disclosure Schedule, such shares or interests are owned by Phillips or a
wholly-owned Subsidiary of Phillips free and clear of any material Lien with
respect thereto. Except as described above, as of the date of this Agreement,
there are not, and, at the Closing, there will not be, any capital stock or
other equity interests in any P Chem Subsidiary issued or outstanding or any
subscriptions, options, warrants, calls, rights, convertible securities or other
agreements or commitments of any character obligating any P Chem Subsidiary to
issue, transfer or sell any of its capital stock or other equity interests, or
any agreements, arrangements or understandings granting any person any rights in
any P Chem Subsidiary similar to capital stock or other equity interests. Except
as set forth on Schedule 4.2 of the Phillips Disclosure Schedule, P Chem does
not include any material interest in any corporation, partnership, joint venture
or other entity.

            Section 4.3 Authority; No Violation. (a) Phillips has full corporate
power and authority to execute and deliver this Agreement and the Amended LLC
Agreement, and to consummate the transactions contemplated by this Agreement and
the Amended LLC Agreement. The execution and delivery of this Agreement and the
Amended LLC Agreement and the consummation of the transactions contemplated by
this Agreement and the Amended LLC Agreement have been duly and validly approved
by all corporate action on the part of Phillips. No other corporate proceedings
on the part of Phillips or any of its Affiliates are necessary to approve this
Agreement or the Amended LLC Agreement or to consummate the transactions
contemplated by this Agreement or the Amended LLC Agreement. This Agreement has
been duly and validly executed and delivered by Phillips, and, assuming due
authorization, execution and delivery by Chevron and the Company, constitutes a
valid and binding obligation of Phillips, enforceable against Phillips in
accordance with its terms.

            (b) Phillips has full corporate power, right and authority to
transfer and convey, or cause to be transferred and conveyed, to the Company at
the Closing, P Chem.

            (c) The execution, delivery and performance of this Agreement and
the Amended LLC Agreement by Phillips do not, and the consummation by Phillips
of the transactions contemplated by this Agreement and the Amended LLC Agreement
will not, constitute (i) a breach or violation of, or a default under, the
certificate of incorporation or by-laws of Phillips, (ii) constitute a breach or
violation of, or a default under, or give rise to any Lien, any buy-out right,
any right of first offer or refusal, any acceleration of remedies, or any
right of termination under or trigger any "change of control" rights or remedies
under, any indenture, license, contract, agreement or other instrument to which
Phillips is a party or by which any of its properties or assets may be bound, or
(iii) assuming compliance with the applicable requirements of the HSR Act,
violate any law, rule, regulation, judgment, decree or order applicable to P
Chem or any of its properties or assets, except, in the case of (ii) and (iii),
for such breaches, violations, defaults, Liens, accelerations or rights as would
not be reasonably expected, individually or in the aggregate, to result in a
Material Adverse Effect on P Chem or to adversely affect the ability of Phillips
to consummate the transactions contemplated by this Agreement or the Amended LLC
Agreement.

            Section 4.4 Consents and Approvals. Except for applicable
requirements of the HSR Act and the European Commission, no notice to, filing
with, authorization of, exemption by, or consent or approval of, or the taking
of any other action in respect of, any Governmental Entity or any other Person
on the part of Phillips is necessary for the consummation by Phillips of the
transactions contemplated by this Agreement, except where the failure to provide
such notice, make such filing or obtain such authorization, exemption, consent
or approval would not, individually or in the aggregate, be reasonably expected
to result in a Material Adverse Effect on P Chem or to adversely affect the
ability of Phillips to consummate the transactions contemplated by this
Agreement or the Amended LLC Agreement.

            Section 4.5 Licenses; Compliance with Applicable Law. Phillips or
a P Chem Subsidiary holds all licenses, franchises, permits and authorizations
(each, a "Permit") necessary for the lawful conduct of P Chem's businesses under
and pursuant to, and has complied with and is not in default under, any
applicable laws, statutes, orders, rules or regulations of any Governmental
Entity relating to P Chem, except, in each case, where the failure to hold such




                                      -18-


<PAGE>


Permit or such noncompliance or default would not, individually or in the
aggregate, have a Material Adverse Effect on P Chem. To Phillips' knowledge, the
businesses of P Chem are not being and have not been conducted in violation of
any applicable laws or any orders, writs, injunctions or decrees of any
Governmental Entity, except for such violations, if any, as would not,
individually or in the aggregate, have a Material Adverse Effect on P Chem.

            Section 4.6 Financial Statements; Undisclosed Liabilities. Phillips
has previously made available to Chevron copies of the unaudited consolidated
balance sheets of P Chem as of December 31, for the fiscal years 1998 and 1999,
and the related unaudited consolidated statements of income and cash flows for
the years then ended. The financial statements referred to in this Section 4.6
fairly present in all material respects (except for the absence of footnotes)
the financial position of P Chem at December 31, 1999 and 1998, and the results
of its operations and its cash flows for the respective fiscal periods therein
set forth. The financial statements described in this Section 4.6 (including the
related notes, if any) comply in all material respects with applicable internal
Phillips accounting requirements with respect thereto; and these statements
(including the related notes, if any) have been prepared in all material
respects in accordance with GAAP consistently applied during the periods
involved, except for the absence of footnotes. P Chem does not have any
liabilities required by GAAP to be set forth on a consolidated balance sheet of
P Chem (other than as set forth in the notes thereto, if any), except (i) as set
forth on the P Chem December 31 Balance Sheet, (ii) for liabilities incurred in
the ordinary course of business since December 31, 1999 and (iii) for
liabilities that would not reasonably be expected to have a Material Adverse
Effect on P Chem. The financial statements described in this Section 4.6
(including the related notes, if any) are derived from the financial statements
used in preparing Phillips' audited financial statements set forth in Phillips'
filings with the SEC. Schedule 4.6 of the Phillips Disclosure Schedule sets
forth the P Chem December 31 Balance Sheet.

            Section 4.7  Brokers' Fees.  Except for Goldman, Sachs & Co.,
neither Phillips nor any Affiliate of Phillips nor any of their respective
officers or directors has employed any broker or finder or incurred any
Liability for any brokers' fees, commissions or finders' fees in connection with
the transactions contemplated by this Agreement or the Amended LLC Agreement.

            Section 4.8 Absence of Certain Changes or Events. From December 31,
1999 through the date of this Agreement, the businesses of P Chem have been
operated in the ordinary and normal course in all material respects, and there
has not been:

            (a) any event (whether covered by insurance or not) that,
individually or in the aggregate, has had or would reasonably be expected to
have a Material Adverse Effect on P Chem;

            (b) any increase in compensation (including severance or termination
pay) payable to or to become payable to any consultants, officers, directors,
employees or agents working in connection with the businesses of P Chem or any

made to, for or with any of such consultants, officers, directors, employees or
agents, in each case, other than (i) general increases or changes reasonably
consistent with past practices and applicable to at least 10% of the employees
of




                                      -19-

Phillips and its Subsidiaries, or (ii) other increases that are in accordance
with past practice and are not material in the aggregate;

            (c) any change in financial accounting methods, principles or
practices by P Chem materially affecting its assets, Liabilities or businesses,
except insofar as such change may have been required by a change in GAAP;

            (d) any indebtedness for borrowed money incurred by P Chem other
than from Phillips or its Affiliates, any issuance of debt securities by P Chem
other than to Phillips or its Affiliates, any assumption, guarantee, endorsement
or other action that would result in P Chem having responsibility for the
obligations of any other Persons, or any mortgage or encumbrance on properties
or assets of P Chem other than Liens that do not materially restrict or detract
from the value of such properties or assets; or

            (e) any declaration, setting aside or payment of any distribution
(other than in cash), directly or indirectly, except as permitted by this
Agreement.

            Section 4.9  Legal Proceedings. (a) As of the date hereof, neither
Phillips nor any of its Subsidiaries is a party to any, and there are no pending
or, to Phillips' knowledge, threatened, legal, administrative, arbitral or other
proceedings, claims, actions or governmental or regulatory investigations of any
nature against Phillips or any of its Subsidiaries that (i) individually or in
the aggregate, would reasonably be expected to have a Material Adverse Effect on
P Chem, or (ii) would adversely affect the ability of Phillips to consummate the
transactions contemplated by this Agreement or the Amended LLC Agreement.
Schedule 4.9 of the Phillips Disclosure Schedule lists all legal,
administrative, arbitral or other proceedings relating to the businesses and
operations of P Chem to which Phillips or any of its Subsidiaries is a party,
and all pending or, to Phillips' knowledge, theatened claims which are material
to the business and operations of P Chem.

            (b) There is no injunction, order, judgment or decree imposed upon
P Chem, or any assets of P Chem, which has had, or would reasonably be expected
to have, a Material Adverse Effect on P Chem.

            Section 4.10 Contracts. (a) Schedule 4.10(a) of the Phillips
Disclosure Schedule sets forth a true and complete list, as of the date of this
Agreement, of all contracts, agreements and commitments of the following
categories, whether oral or written, express or implied, to which Phillips or

Contracts"):

               (i)   any employment, product design or development, personal

               (ii)  any contract involving or requiring expenditures or

<PAGE>


               (iii)  any contract containing covenants limiting the freedom
of P Chem to engage in any line of business or compete with any Person or
operate at any location;

               (iv)   any contract granting a right of first refusal or first
negotiation other than for the purchase of goods or services in the aggregate
less than $2,000,000;

               (v)    any partnership or joint venture agreement;

               (vi)   any agreement for the acquisition, sale or lease of

               (ix)   any contract between P Chem, on the one hand, and
Phillips or any Affiliate of Phillips (other than P Chem), on the other hand;
and

               (x)    any commitments and agreements to enter into any of
the foregoing.

            (b) Each P Chem Material Contract is a valid, binding and
enforceable (except as such enforceability may be subject to any bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other laws, now
or hereafter in effect, relating to or limiting creditors' rights generally)
obligation of P Chem. There is no default under any P Chem Material Contract by
P Chem or, to Phillips' knowledge, by any other party thereto, and no event has
occurred that with the lapse of time or the giving of notice or both would
constitute a default thereunder by P Chem, or, to Phillips' knowledge, any other
party, which default or event, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect on P Chem. As of the
date of this Agreement, no party to any P Chem Material Contract has given
notice to P Chem or made a claim against P Chem with respect to any breach or
default thereunder, which breach or default, individually or in the aggregate,
would reasonably be expected to have a Material Adverse Effect on P Chem. As of
the date of this Agreement, there has been no amendment or modification of any
of the P Chem Material Contracts, except as specifically listed on Schedule
4.10(a) of the Phillips Disclosure Schedule. The enforceability of any P Chem
Material Contract shall not be impaired by the execution and delivery of this
Agreement or the Amended LLC Agreement or the consummation of the transactions
contemplated hereby or thereby, and, as of the date of this Agreement, no P Chem
Material Contract requires that a transaction of the kind contemplated by this
Agreement or the Amended LLC Agreement receive the approval of any party to such
P Chem Material Contract, except where such impairments or failures to receive
approvals, individually or in the aggregate, would not reasonably be expected to
have a Material Adverse Effect on P Chem.

            (c) As of the date of this Agreement, Phillips has delivered to
Chevron or otherwise made available to Chevron at the offices of Phillips or its
Subsidiaries true, correct and complete copies of all P Chem Material Contracts.

and data, including trade secrets, as are necessary to permit P Chem to conduct
its businesses as currently conducted (collectively, the "P Chem Intellectual

use would not, individually or in the aggregate, have a Material Adverse Effect
on P Chem.

            (b) To Phillips' knowledge, the conduct of the businesses of P Chem
as currently conducted does not infringe the valid proprietary rights of any
third party, and there are no present or threatened infringements of the P Chem

Adverse Effect on P Chem. There are no pending or, to Phillips' knowledge,

            (d) There does not now exist, nor do any circumstances exist that

            (e) Except as specifically provided in Annex A and except for stock
options granted by Phillips to P Chem Employees, neither the execution and

insurance, immigration, and occupational safety and health, and is not engaged

be expected to cause a Material Adverse Effect on P Chem. Neither Phillips nor
any Subsidiary of Phillips is a party to any collective bargaining agreement or
other labor union contract with respect to any P Chem Employee, and, to

to organize any P Chem Employees. No claim has been made by any labor

P Chem.

            Section 4.18 Year 2000. Phillips has developed and implemented a

knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of its acquisition of Company Interests.

present intention of distributing or selling the Company Interests. Phillips
agrees that the Company Interests may not be sold, transferred, offered for
sale, pledged, hypothecated or otherwise disposed of without registration under

available under the Securities Act, and without compliance with foreign
securities laws, in each case, to the extent applicable.

elsewhere in this Agreement or in the Phillips Disclosure Schedule, as of the

carry on its businesses as it is now being conducted, and is duly licensed or
qualified to do business in each jurisdiction in which the nature of the
businesses conducted by it or the character or location of the properties and
assets owned or leased by it makes such licensing or qualification necessary,
except where the failure to be so licensed or qualified would not have,
individually or in the aggregate, a Material Adverse Effect on either Chevron or
C Chem, as applicable. True and complete copies of the certificate of
incorporation and by-laws or comparable organizational documents of each C Chem
Subsidiary, in effect as of the date of this Agreement, have previously been
made available by Chevron to Phillips.

            Section 5.2 Capitalization. Schedule 5.2 of the Chevron Disclosure

respective jurisdictions of organization and capitalization, as of the date
hereof. All of the outstanding shares of capital stock or outstanding limited
liability company interests of each C Chem Subsidiary are validly issued, fully
paid and nonassessable, and, except as set forth on Schedule 5.2 of the Chevron
Disclosure Schedule, such shares or interests are owned by Chevron or a
wholly-owned Subsidiary of Chevron free and clear of any material Lien with
respect thereto. Except as described above, as of the date of this Agreement,
there are not, and, at the Closing, there will not be, any capital stock or
other equity interests in any C Chem Subsidiary issued or outstanding or any
subscriptions, options, warrants, calls, rights, convertible securities or other
agreements or commitments of any character obligating any C Chem Subsidiary to
issue, transfer or sell any of its capital stock or other equity interests, or
any agreements, arrangements or understandings granting any person any rights in
any C Chem Subsidiary similar to capital stock or other equity interests. Except

the Amended LLC Agreement. The execution and delivery of this Agreement and the
Amended LLC Agreement and the consummation of the transactions contemplated by
this Agreement and the Amended LLC Agreement have been duly and validly approved
by all corporate action on the part of Chevron. No other corporate proceedings
on the part of Chevron or any of its Affiliates are necessary to approve this
Agreement or the Amended LLC Agreement or to consummate the transactions
contemplated by this Agreement or the Amended LLC Agreement. This Agreement has
been duly and validly executed and delivered by Chevron, and, assuming due
authorization, execution and delivery by Phillips and the Company, constitutes a
valid and binding obligation of Chevron, enforceable against Chevron in
accordance with its terms.

            (b) Chevron has full corporate power, right and authority to
transfer and convey, or cause to be transferred and conveyed, to the Company at
the Closing, C Chem.

            (c) The execution, delivery and performance of this Agreement and
the Amended LLC Agreement by Chevron do not, and the consummation by Chevron of
the transactions contemplated by this Agreement and the Amended LLC Agreement
will not, constitute (i) a breach or violation of, or a default under, the
certificate of incorporation or by-laws of Chevron, (ii) constitute a breach or
violation of, or a default under, or give rise to any Lien, any buy-out right,
any right of first offer or refusal, any acceleration of remedies, or any




                                      -26-


<PAGE>


right of termination under or trigger any "change of control" rights or remedies
under, any indenture, license, contract, agreement or other instrument to which
Chevron is a party or by which any of its properties or assets may be bound, or
(iii) assuming compliance with the applicable requirements of the HSR Act,
violate any law, rule, regulation, judgment, decree or order applicable to C
Chem or any of its properties or assets, except, in the case of (ii) and (iii),
for such breaches, violations, defaults, Liens, accelerations or rights as would
not be reasonably expected, individually or in the aggregate, to result in a
Material Adverse Effect on C Chem or to adversely affect the ability of Chevron
to consummate the transactions contemplated by this Agreement or the Amended LLC
Agreement.

            Section 5.4 Consents and Approvals. Except for applicable
requirements of the HSR Act and the European Commission, no notice to, filing
with, authorization of, exemption by, or consent or approval of, or the taking
of any other action in respect of, any Governmental Entity or any other Person
on the part of Chevron is necessary for the consummation by Chevron of the
transactions contemplated by this Agreement, except where the failure to provide
such notice, make such filing or obtain such authorization, exemption, consent
or approval would not, individually or in the aggregate, be reasonably expected
to result in a Material Adverse Effect on C Chem or to adversely affect the
ability of Chevron to consummate the transactions contemplated by this Agreement
or the Amended LLC Agreement.

            Section 5.5 Licenses; Compliance with Applicable Law. Chevron or a
C Chem Subsidiary holds all Permits necessary for the lawful conduct of C Chem's
businesses under and pursuant to, and has complied with and is not in default
under, any applicable laws, statutes, orders, rules or regulations of any
Governmental Entity relating to C Chem, except, in each case, where the failure
to hold such Permit or such noncompliance or default would not, individually or
in the aggregate, have a Material Adverse Effect on C Chem. To Chevron's
knowledge, the businesses of C Chem are not being and have not been conducted in
violation of any applicable laws or any orders, writs, injunctions or decrees of
any Governmental Entity, except for such violations, if any, as would not,
individually or in the aggregate, have a Material Adverse Effect on C Chem.

has previously made available to Phillips copies of the unaudited consolidated
balance sheets of C Chem as of December 31, for the fiscal years 1998 and 1999,
and the related unaudited consolidated statements of income and cash flows for
the years then ended. The financial statements referred to in this Section 5.6
fairly present in all material respects (except for the absence of footnotes)
the financial position of C Chem at December 31, 1999 and 1998, and the results
of its operations and its cash flows for the respective fiscal periods therein
set forth. The financial statements described in this Section 5.6 (including the
related notes, if any) comply in all material respects with applicable internal
Chevron accounting requirements with respect thereto; and these statements
(including the related notes, if any) have been prepared in all material
respects in accordance with GAAP consistently applied during the periods
involved, except for the absence of footnotes. C Chem does not have any
liabilities required by GAAP to be set forth on a consolidated balance sheet of
C Chem (other than as set forth on the notes thereto, if any), except (i) as set
forth on the C Chem December 31 Balance Sheet, (ii) for liabilities incurred in
the ordinary course of business since December 31, 1999 and (iii) for
liabilities that would not reasonably be expected to have a Material Adverse

contemplated hereby or thereby, and, as of the date of this Agreement, no C Chem
Material Contract requires that a transaction of the kind contemplated by this

approvals, individually or in the aggregate, would not reasonably be expected to
have a Material Adverse Effect on C Chem.

title or Liens described on Schedules 5.11(a)(i) and 5.11(a)(ii) of the Chevron

lessor under any C Chem Lease to terminate such C Chem Lease prior to the
scheduled expiration thereof, and (iii) neither Chevron nor any C Chem
Subsidiary is currently participating in any discussions or negotiations
regarding termination of any C Chem Lease of a property at which C Chem conducts

the Closing have, such ownership of or such rights by license or other agreement
to use all patents and patent applications, trademarks and service marks,
trademark and service mark registrations and applications, trade names, logos,
copyrights and copyright registrations and applications, proprietary information
and data, including trade secrets, as are necessary to permit C Chem to conduct
its businesses as currently conducted (collectively, the "C Chem Intellectual
Property"), except where the failure to have such ownership, license or right to
use would not, individually or in the aggregate, have a Material Adverse Effect
on C Chem.

            (b) To Chevron's knowledge, the conduct of the businesses of C Chem
as currently conducted does not infringe the valid proprietary rights of any
third party, and there are no present or threatened infringements of the C Chem
Intellectual Property by any third party, except, in either case, for such
infringements that would not, individually or in the aggregate, have a Material
Adverse Effect on C Chem. There are no pending or, to Chevron's knowledge,
threatened infringement proceedings, litigation or claims by any Person against

            Section 6.1 Investigation of Business; Access to Properties and
Records. (a) From the date of this Agreement through the Closing, Phillips and
Chevron shall cause P Chem and C Chem, respectively, to afford to
representatives of the other Party reasonable access to their offices,
properties, books and records, during normal business hours, in order that the
other Party may have a full opportunity to make such investigations as it
desires of their affairs; PROVIDED, HOWEVER, that such investigation shall be at
reasonable times and upon reasonable notice and shall not unreasonably disrupt
the personnel or operations of Phillips or P Chem, or Chevron or C Chem,
respectively. All requests for access to the offices, properties, books, and
records relating to P Chem or C Chem shall be made to such representatives as
may be designated in writing by Phillips or Chevron, as appropriate (the
"Designated Representatives"), which Designated Representatives shall be solely
responsible for coordinating all such requests and all access permitted
hereunder. Neither Phillips nor Chevron nor their respective representatives
shall contact any of the employees, customers or suppliers of the other Party
and its Subsidiaries, in connection with the transactions contemplated by this
Agreement and the Amended LLC Agreement, whether in person or by telephone, mail
or other means of communication, without the specific prior written
authorization of the other Party's Designated Representatives, which consent
shall not be unreasonably withheld.

            (b) Any information provided to a Party or its representatives
pursuant to this Agreement or the Amended LLC Agreement shall be held by such
Party and its representatives in accordance with, and shall be subject to the
terms of, the Confidentiality Agreement and the Amended LLC Agreement, as
applicable. From and after the Closing, each Party shall, and shall cause its
Affiliates to, maintain in confidence and not use nonpublic information of the

            (c) Except as contemplated by this Agreement and the Amended LLC
Agreement, each of Phillips and Chevron agrees, and agrees to cause its
representatives not to, until the earlier of the Closing or termination of this
Agreement in accordance with its terms, not to (i) enter into any agreement with
any third party, or engage in any discussions with attorneys, investment
bankers, other advisors or representatives, or any third party, regarding a
transaction involving the sale of, or creation of a joint venture involving, all
or any material portion of the

or dispose of such books and records, to offer first in writing, at least 60
days prior to such destruction or disposition, to surrender them to Phillips or
Chevron, respectively, and (ii) following the Closing Date to afford Phillips
and Chevron, their respective accountants and counsel, during normal business
hours, upon reasonable notice, full access to such books and records to the
extent that such access may be requested for any legitimate purpose at no cost
to Phillips or Chevron (other than for reasonable out-of-pocket expenses);
PROVIDED, HOWEVER, that nothing herein shall limit any of Phillips' or Chevron's
respective rights of discovery pursuant to any legal proceeding. The Company
shall have the same rights, and Phillips and Chevron, respectively, the same
obligations, as are set forth in this Section 6.1(d) with respect to any books,
non-privileged records and employees of Phillips or Chevron pertaining to the
Company and its Subsidiaries, with the exception of Tax Returns. The Company
will provide additional information to the extent reasonably requested and
required by Phillips or Chevron for a legitimate purpose.

conditions of this Agreement and the Amended LLC Agreement, each of Phillips and
Chevron agrees to use its best commercially reasonable efforts to promptly (i)
take, or cause to be taken, all actions and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement
and the Amended LLC Agreement, (ii) obtain and maintain all approvals, consents,

will consult each other on, all submissions and communications relating to P
Chem or C Chem, as the case may be, made with any third party and/or any
Governmental Entity in connection with the transactions contemplated by this
Agreement and the Amended LLC Agreement.

            (b) Notwithstanding anything to the contrary in this Agreement, in

applicable, and consummated prior to the Closing pursuant to Sections 6.2, 6.4
or 6.5, at the Closing, all after-Tax proceeds from such sale shall be held by P
Chem or C Chem, as applicable, and the representations and warranties in
Articles IV and V shall be deemed to be adjusted appropriately.

            (c) In furtherance and not in limitation of the foregoing, each of

Anything in this Agreement to the contrary notwithstanding, this Agreement shall

<PAGE>


            (c) The failure by the Parties to obtain any required consent,
waiver, confirmation, novation or approval with respect to any contract, lease
or Permit shall not relieve either Party from its obligation to consummate at
the Closing the transactions contemplated by this Agreement or the Amended LLC
Agreement or any other obligations hereunder or thereunder unless such failures
would, in the aggregate, have a Material Adverse Effect on C Chem or P Chem.

            (d) If any consent, waiver, confirmation, novation or approval is
not obtained prior to the Closing with respect to any contract, lease or Permit
described in subparagraph (b) of this Section 6.8, then Phillips or Chevron, as
applicable, shall establish, or cause to be established, an agency type or other
arrangement satisfactory to the other Party and to the Company under which
Phillips or Chevron, as applicable, shall hold, or cause to be held, such
interest, lease or Permit for the Company and the Company would obtain the
Claims and benefits and assume the corresponding Liabilities thereunder in
accordance with this Agreement (including by means of any subcontracting,
sublicensing or subleasing arrangement) or under which Phillips or Chevron, as
applicable, would enforce, or cause to be enforced, at the direction of and for
the benefit of the Company with the Company assuming and agreeing to pay
Chevron's or Phillips' (or their respective Affiliates') obligations and
expenses, any and all Claims and benefits of Phillips or Chevron (or their
respective Affiliates) against a third party thereto; PROVIDED, HOWEVER, that
Phillips' or Chevron's obligation to maintain, or cause to be maintained, any
such arrangement shall terminate upon the earliest to occur of: (i) the
expiration or termination of such contract, lease or Permit in accordance with
its terms (without regard to any extensions, automatic or otherwise); or (ii)
with regard to a Permit, such time as the Company shall obtain a Permit in
reasonable substitution therefor, or have its application for such substitute
Permit denied. In any such arrangement, Phillips or Chevron, as applicable,
shall promptly pay, or cause to be paid, to the Company when received, all
moneys relating to the period after the Closing Date received by it under any
contract or any Claim, right or benefit arising thereunder not transferred
pursuant to this Section 6.8, and the Company shall promptly pay, perform or
discharge when due any Liability arising thereunder after the Closing Date.

            (b) The Company and Chevron acknowledge that, from and after the

<PAGE>


agreements relating to operating and supply commitments (including pricing)
between, the P Chem Subsidiaries and/or the Company and/or its wholly owned
subsidiaries, on the one hand, and Phillips and its Affiliates, on the other
hand. Schedule 6.11(b)(i) of the Phillips Disclosure Schedule sets forth a list
of such agreements to be entered into as of the Closing Date in the forms
attached to Schedule 6.11(b)(i) of the Phillips Disclosure Schedule, such forms
being agreed to as of the date hereof. Section 6.11(b)(ii) of the Phillips
Disclosure Schedule sets forth a list of such agreements to be entered into as
of the Closing Date (and the assets, properties or subject matter to which such
agreements pertain) which shall be based on customary terms consistent with past
practice and consistent in all material respects with financial information
previously provided by Phillips to Chevron with regard to P Chem, except as may
otherwise be provided in Schedule 6.11(b)(ii). The C Chem Subsidiaries and/or
the Company and/or its wholly owned subsidiaries, on the one hand, and Chevron
and its Affiliates, on the other hand, shall enter into agreements relating to
operating and supply commitments (including pricing) between, the C Chem
Subsidiaries and/or the Company and/or its wholly owned subsidiaries, on the one
hand, and Chevron and its Affiliates, on the other hand. Schedule 6.11(b)(i) of
the Chevron Disclosure Schedule sets forth a list of such agreements to be
entered into as of the Closing Date in the forms attached to Schedule 6.11(b)(i)
of the Chevron Disclosure Schedule, such forms being agreed to as of the date
hereof. Section 6.11(b)(ii) of the Chevron Disclosure Schedule sets forth a list
of such agreements to be entered into as of the Closing Date (and the assets,
properties or subject matter to which such agreements pertain) which shall be
based on customary terms consistent with past practice and consistent in all
material respects with financial information previously provided by Chevron to
Phillips with regard to C Chem, except as may otherwise be provided in Schedule
6.11(b)(ii).

            (c) The P Chem Subsidiaries and/or the Company and/or its wholly
owned subsidiaries, on the one hand, and Phillips and its Affiliates, on the
other hand, shall enter into the lease and sublease agreements set forth in
Schedule 6.11(c) of the Phillips Disclosure Schedule as of the Closing Date, in
the forms attached to Schedule 6.11(c) of the Phillips Disclosure Schedule, such
forms being agreed to as of the date hereof. The C Chem Subsidiaries and/or the
Company and/or its wholly owned subsidiaries, on the one hand, and Chevron and

agreements set forth in Schedule 6.11(c) of the Chevron Disclosure Schedule as
of the Closing Date, in the forms attached to Schedule 6.11(c) of the Chevron
Disclosure Schedule, such forms being agreed to as of the date hereof.

            (d) With regard to assets and facilities involving P Chem, C Chem
or the Company and/or its wholly owned subsidiaries, on the one hand, and
Phillips or Chevron, on the other hand, other than assets and facilities for
which arrangements have been provided in the agreements listed in Schedule
6.11(b) or 6.11(c) of the Chevron Disclosure Schedule or in Schedule 6.11(b) or
6.11(c) of the Phillips Disclosure Schedule, such assets and facilities shall,
to the extent reasonably practicable (including taking into account the costs of
any actions taken), be severed, divided or otherwise separated from each other
so that the P Chem Subsidiaries, C Chem Subsidiaries or the Company and/or its
wholly owned subsidiaries, on the one hand, and Phillips or Chevron, on the
other hand, shall own and control their respective assets as of the Closing
Date; PROVIDED, HOWEVER, that none of Phillips, Chevron or the Company or its
wholly owned subsidiaries shall be obligated to make significant expenditures to
effect such separation prior to the Closing Date. Actions taken and expenditures
incurred to separate




                                      -43-


<PAGE>


the shared assets and facilities shall be subject to the agreement of Phillips,
Chevron and the Company. Such separation may include subdivision of real
property, subleasing or other division of shared buildings or premises and
allocation of shared working capital, equipment and other assets. Such
separation shall be effected in a manner that does not unreasonably disrupt
either the businesses of P Chem, C Chem or the Company or its wholly owned
subsidiaries or the businesses of Phillips or Chevron, and minimizes, to the
extent practicable, current and future costs (and losses of tax or other
economic benefits) of the respective businesses. With respect to any assets or
facilities that cannot reasonably be separated or otherwise allocated as
provided above, (i) right, title and interest shall be allocated between
Phillips and its Affiliates (other than the P Chem Subsidiaries, the Company
and/or its wholly owned subsidiaries) and the Company and between Chevron and
its Affiliates (other than the C Chem Subsidiaries, the Company and/or its
wholly owned subsidiaries) based on which entity predominantly uses or holds
such asset or facility for use or to which entity's business the asset or
facility predominantly relates, and (ii) the other entity shall have a right to
use such assets or facilities in its businesses in a manner consistent with past
practice for a period which is coterminous with the life of the asset or
facility described in (i) (and the coextensive obligation to pay its allocable
share of any costs or expenses related to such asset or facility pursuant to the
last sentence of this Section 6.11(d)). To the extent the separation of assets
and facilities cannot be achieved in a reasonably practicable manner, the
parties will enter into appropriate arrangements regarding the shared assets and
facilities. Such arrangements shall provide that any costs related to the use of
shared assets or facilities that are not separated as of the Closing Date shall
be allocated, with respect to the twelve month period beginning immediately
after the Closing Date, based on the methodology historically used by Phillips
or Chevron, as applicable, and, for any period thereafter, using such reasonable
manner as agreed by Phillips and the Company or by Chevron and the Company, as
applicable; provided, that the Company may terminate such arrangements at any
time after six months after the Closing Date upon written notice to the other
party or parties to such arrangements, and any party to such arrangements may
terminate the arrangements at any time after twelve months from the Closing Date
upon written notice to the other party or parties to such arrangements.

            (e) From and after the Closing Date, (i) Phillips shall be entitled
to require the Company or P Chem, as applicable, to convey, transfer, lease or
assign to Phillips or a Phillips Subsidiary (other than the Company or a P Chem
Subsidiary) any Phillips Excluded Assets that shall not have been conveyed,
transferred, leased or assigned by P Chem prior to the Closing, and (ii) Chevron
shall be entitled to require the Company or C Chem, as applicable, to convey,
transfer, lease or assign to Chevron or a Chevron Subsidiary (other than the
Company or a C Chem Subsidiary) any Chevron Excluded Assets that shall not have
been conveyed, transferred, leased or assigned by C Chem prior to the Closing.

            Section 6.12  Company Integration Expenses.  All integration
expenses (excluding corporate expenses of Phillips or Chevron) shall be borne
by the Company.

            Section 6.13 Insurance. (a) Phillips and the Company acknowledge
that the programs and policies of insurance maintained by Chevron and its
Affiliates to provide coverage in favor of the C Chem operations shall be
terminated effective 12:01 A.M. on the day following the Closing Date. From and
after the Closing Date, except as otherwise provided in this Agreement, all risk
of loss with respect to properties and assets of C Chem shall be borne by the




                                      -44-


<PAGE>


Company, notwithstanding any insurance coverage that Phillips or Chevron have
for their own benefit. With respect to events occurring after December 31, 1999
but prior to the Closing Date, the C Chem operations shall be entitled to the
benefits of insurance from independent sources (not affiliated with Chevron),
including insurance benefits from third-party reinsurance of any
Chevron-affiliated insurance company maintained by or for the benefit of the C
Chem operations with respect to properties and assets of C Chem; PROVIDED,
HOWEVER, that, notwithstanding anything to the contrary contained in this
Agreement, the Company is not an "insured" under any Chevron-affiliated
insurance company policy with respect to events occurring from and after the
Closing Date and therefore is not entitled to any insurance recovery under such
insurance; PROVIDED, HOWEVER, that, notwithstanding anything to the contrary
contained in this Agreement, Chevron retains its status as an "insured" under
any Chevron-affiliated insurance company policy including its rights to such
insurance for liability arising out of the transactions contemplated by this
Agreement. Further, the Company shall indemnify and hold harmless Chevron and
its Affiliates from any retroactive premiums imposed by any insurer under
programs or policies maintained by Chevron prior to the Closing as a result of
any claims made after the Closing Date with respect to the properties and assets
of C Chem, regardless of the date of loss.

            (b) Chevron and the Company acknowledge that the programs and
policies of insurance maintained by Phillips and its Affiliates to provide
coverage in favor of the P Chem operations shall be terminated effective 12:01
A.M. on the day following the Closing Date. From and after the Closing Date,
except as otherwise provided in this Agreement, all risk of loss with respect to
properties and assets of P Chem shall be borne by the Company, notwithstanding
any insurance coverage that Phillips or Chevron have for their own benefit. With
respect to events occurring after December 31, 1999 but prior to the Closing
Date, the P Chem operations shall be entitled to the benefits of insurance from
independent sources (not affiliated with Phillips), including insurance benefits
from third-party reinsurance of any Phillips-affiliated insurance company
maintained by or for the benefit of the P Chem operations with respect to
properties and assets of P Chem; PROVIDED, HOWEVER, that, notwithstanding
anything to the contrary contained in this Agreement, from and after the Closing
Date, the Company is not an "insured" under any Phillips-affiliated insurance
company policy with respect to events occurring from and after the Closing Date
and therefore is not entitled to any insurance recovery under such insurance;
PROVIDED, HOWEVER, that, notwithstanding anything to the contrary contained in
this Agreement, Phillips retains its status as an "insured" under any
Phillips-affiliated insurance company policy including its rights to such
insurance for liability arising out of the transactions contemplated by this
Agreement. Further, the Company shall indemnify and hold harmless Phillips and
its Affiliates from any retroactive premiums imposed by any insurer under
programs or policies maintained by Phillips prior to the Closing as a result of
any claims made after the Closing Date with respect to the properties and assets
of P Chem, regardless of the date of loss.

            (c) Each of Phillips and Chevron shall cooperate to cause the
Company to have insurance from independent sources (not affiliated with either
Phillips or Chevron) in such amounts and against such risks and losses as are
customary for companies conducting the businesses to be conducted by the
Company.

            Section 6.14 Guarantees. (a) In the event that, after the Closing
Date, Phillips or any Affiliate of Phillips (other than the Company and its
Subsidiaries) remains liable for any guarantees (whether of payment or
performance), letters of credit or other undertakings it has delivered prior to
the Closing Date to others for the benefit of P Chem, the Company agrees to
indemnify and hold harmless Phillips or such Affiliate of Phillips from any
cost, expense or loss (including reasonable attorneys' fees) incurred by
Phillips or such Affiliate of Phillips arising, directly or indirectly,
therefrom, except insofar as such cost, expense or loss constitutes or arises
from a matter with respect to which the Company or any of its Affiliates
(excluding Phillips) is entitled to indemnification hereunder. Any such
guarantees, letters of credit or other undertakings (including performance
guarantees) are set forth on Schedule 6.14(a) of the Phillips Disclosure
Schedule. The Company shall use its commercially reasonable best efforts
(including an offer of a substitute guarantee, letter of credit or undertaking)
to cause or procure the release, as soon as practicable following the Closing
Date, of all Liabilities of Phillips or any Affiliate of Phillips (other than
the Company and its Subsidiaries) with respect to such guaranties, letters of
credit or other undertakings from any of the P Chem Liabilities; PROVIDED
HOWEVER, that neither the Company nor its Subsidiaries shall incur any cost or
expense in causing or procuring such release.

            (b) In the event that, after the Closing Date, Chevron or any
Affiliate of Chevron (other than the Company and its Subsidiaries) remains
liable for any guarantees (whether of payment or performance), letters of credit
or other undertakings it has delivered prior to the Closing Date to others for
the benefit of C Chem, the Company agrees to indemnify and hold harmless Chevron
or such Affiliate of Chevron from any cost, expense or loss (including
reasonable attorneys' fees) incurred by Chevron or such Affiliate of Chevron
arising, directly or indirectly, therefrom, except insofar as such cost, expense
or loss constitutes or arises from a matter with respect to which the Company or
any of its Affiliates (excluding Chevron) is entitled to indemnification
hereunder. Any such guarantees, letters of credit or other undertakings
(including performance guarantees) are set forth on Schedule 6.14(b) of the
Chevron Disclosure Schedule. The Company shall use its commercially reasonable
best efforts (including an offer of a substitute guarantee, letter of credit or
undertaking) to cause or procure the release, as soon as practicable following
the Closing Date. of all Liabilities of Chevron or any Affiliate of Chevron
(other than the Company and its Subsidiaries) with respect to such guaranties,
letters of credit or other undertakings from any of the C Chem Liabilities;
PROVIDED HOWEVER, that neither the Company nor its Subsidiaries shall incur any
cost or expense in causing or procuring such release.

            Section 6.15 Actions by Affiliates of Phillips and Chevron. Each of
Phillips and Chevron shall ensure that each of its Affiliates (other than,
following the Closing, the Company and its Subsidiaries) takes all actions
necessary to be taken by such Affiliate in order to fulfill the obligations of
Phillips or Chevron, as the case may be under this Agreement.

            Section 6.16 Financing. Each of Phillips and Chevron shall use its
commercially reasonable best efforts and cooperate with each other to cause the
Company to secure, by the Closing Date or as soon as practicable thereafter,
bank credit facilities of $1,670,000,000 (or such lesser amount as would allow
the Company to maintain an investment-grade debt rating) on reasonably available
commercial terms mutually agreeable to the Parties (the "Financing"). Upon the
funding of the Financing, the Company shall distribute 50% of the




                                      -46-


<PAGE>


net proceeds of the Financing to Phillips and 50% of the net proceeds of the
Financing to Chevron; PROVIDED, HOWEVER, that the amount distributed to Phillips
shall be reduced by (a) the sum of any P Chem Liability as of the Closing Date
representing indebtedness for borrowed money of a P Chem Subsidiary other than
indebtedness of the entities set forth on Schedule 6.16 of the Phillips
Disclosure Schedule and other than debt incurred in the ordinary course of
business (pursuant to financial arrangements or plans previously disclosed to
Chevron) by such entities, and (b) the SOLP adjustment amount set forth on
Schedule 6.16 of the Phillips Disclosure Schedule, and the amount distributed to
Chevron shall be reduced by the sum of any C Chem Liability as of the Closing
Date representing indebtedness for borrowed money of a C Chem Subsidiary other
than indebtedness of the entities set forth on Schedule 6.16 of the Chevron
Disclosure Schedule and other than debt incurred in the ordinary course of
business (pursuant to financial arrangements or plans previously disclosed to
Phillips) by such entities; and PROVIDED, FURTHER that the distributions set
forth in this sentence shall be done in accordance with the terms of Section
9.2(f) of the Amended LLC Agreement.

            Section 6.17  Special Indemnities and Risk Allocation between the
Company and the Parties.  The provisions of Annex C are hereby incorporated
herein.

            Section 6.18  Intellectual Property. (a) At the Company's election
and expense, P Chem Patent Rights will be transferred and assigned to the
Company upon Closing or at such later time as the Company may specify, subject
to Phillips' reservation of (1) an irrevocable, nonexclusive royalty free
worldwide license extendible to Phillips' Patent Subsidiaries for use in
Phillips' and such Patent Subsidiaries' own business operations and (2) an
irrevocable, nonexclusive royalty free worldwide right to Phillips, or its
designee, to license any of its Affiliates or any third party for use in any
field other than a field primarily related to the P Chem or C Chem business
without obligation to account to any other party. If the Company elects not to
be assigned any or all of the P Chem Patent Rights, Phillips shall provide the
Company with an exclusive license under such P Chem Patent Rights as indicated
in subsection (b) below. Notwithstanding the foregoing, Phillips shall not be
obligated to assign to the Company title to specific letters patent and patent
applications which contain claims that cover technology and inventions that are
not primarily used by or identified as relating to the P Chem business or to the
extent that such assignment would compromise or adversely impact the validity or
enforceability of other letters patent and patent applications owned by
Phillips. Nothing in this Agreement shall be deemed to require that Phillips
obtain or maintain any patent; provided, however, that prior to Phillips'
abandonment of any P Chem patent by failure to pay maintenance fees or taxes or
by disclaimer of rights or other dedication to the public, Phillips will offer
to assign such P Chem patent to the Company at the Company's expense.

            (b) Upon Closing, Phillips shall and shall cause, if necessary,
its Patent Subsidiaries to grant to the Company the exclusive, irrevocable,
royalty free worldwide right and license, including the right to sublicense, to
practice, make, use and sell under all P Chem Proprietary Technology and P Chem
Patent Rights not otherwise assigned to Company; PROVIDED, HOWEVER, that
Phillips reserves (1) an irrevocable, nonexclusive royalty free worldwide
license extendible to Phillips' Patent Subsidiaries for use in Phillips' and
such Patent Subsidiaries' own business operations and (2) an irrevocable,
nonexclusive royalty free worldwide right to Phillips, or its designee, to
license any of its Affiliates or any third party for use in any field other than
a field primarily related to the P Chem or C Chem business without




                                      -47-


<PAGE>


obligation to account to any other party. Phillips shall and shall cause its
Affiliates and third parties to take appropriate measures to protect the
confidentiality of P Chem Proprietary Technology and to limit its use, which
shall be no less stringent than measures Phillips takes with respect to its own
proprietary technology of the same type and shall cause its Affiliates and third
parties to accept any applicable restrictions placed on proprietary technology
by others.

            (c) The Company shall have (1) an irrevocable, royalty-free
worldwide license under any proprietary technology owned or otherwise licensable
by Phillips or its Patent Subsidiaries not contained in the definition of P Chem
Proprietary Technology and (2) an irrevocable, royalty-free worldwide immunity
from suit under any patent rights which are owned or otherwise licensable by
Phillips or its Patent Subsidiaries not contained within the definition of P
Chem Patent Rights, insofar, and only insofar as such proprietary technology and
claims of such patent rights cover technology and inventions that are used in
the P Chem or C Chem business as of the Closing Date, or which embody technology
or inventions relating to the P Chem or C Chem business conceived by the Company
or on its behalf prior to the later of (i) December 31, 2000 or (ii) the
six-month anniversary of the Closing Date, provided such patent rights are based
on applications for patents filed or claiming priority from applications filed
heretofore or hereafter prior to three years after the Closing Date, in each
case subject to the terms and conditions, including the obligation to account to
third parties, under which such rights are held. Such license and immunity from
suit shall be limited to the conduct of the Company's business operations
primarily related to the P Chem or C Chem business, including without limitation
research, development, and demonstration activities, the manufacture, use, or
sale of P Chem or C Chem products and the licensing of P Chem or C Chem
technology by the Company, and may be extended by the Company to its Affiliates,
contractors, suppliers, customers and other third parties, only as appropriate
for the purpose of conducting such P Chem or C Chem business and P Chem or C
Chem licensing operations; PROVIDED, HOWEVER, that no licenses or immunities
will be granted to Company covering technology and inventions that are part of
Phillips non-P Chem technology licensing packages being offered as of the date
that is the later of December 31, 2000 or the six-month anniversary of the
Closing Date, except under separate agreement by the Company and Phillips
thereto. The Company shall and shall cause its Affiliates and third parties to
take appropriate measures to protect the confidentiality of such proprietary
technology and to limit its use as provided above, which shall be no less
stringent than measures the Company takes with respect to its own proprietary
technology of the same type and shall cause its Affiliates and third parties to
accept any applicable contractual restrictions placed on proprietary technology
obtained from others..

            (d) Promptly after the later of (i) December 31, 2000 or (ii) the
six-month anniversary of the Closing Date, Phillips shall fully disclose and, if
necessary, shall cause its Patent Subsidiaries to fully disclose and make
available to the Company any and all P Chem Proprietary Technology not
theretofore disclosed and made available to Company, including any inventions
within the scope of the P Chem Patent Rights, and shall cooperate and cause its
personnel to cooperate with the Company or its nominee as may be reasonably
required in order to obtain patent protection therefor.

            (e) At the Company's election and expense, C Chem Patent Rights will
be transferred and assigned to the Company upon Closing or at such later time as
the Company may specify, subject to Chevron's reservation of (1) an irrevocable,
nonexclusive royalty free




                                      -48-


<PAGE>


worldwide license extendible to Chevron's Patent Subsidiaries for use in
Chevron's and such Patent Subsidiaries' own business operations and (2) an
irrevocable, nonexclusive royalty free worldwide right to Chevron, or its
designee, to license its Affiliates or any third party for use in any field
other than a field primarily related to the P Chem or C Chem business without
obligation to account to any other party. If the Company elects not to be
assigned any or all of the C Chem Patent Rights, Chevron shall provide the
Company with an exclusive license under such C Chem Patent Rights as indicated
in subsection (f) below. Notwithstanding the foregoing, Chevron shall not be
obligated to assign to the Company title to specific letters patent and patent
applications which contain claims that cover technology and inventions that are
not primarily used by or identified as relating to the C Chem business or to the
extent that such assignment would compromise or adversely impact the validity or
enforceability of other letters patent and patent applications owned by Chevron.
Nothing in this Agreement shall be deemed to require that Chevron obtain or
maintain any patent; provided, however, that prior to Chevron's abandonment of
any C Chem patent by failure to pay maintenance fees or taxes or by disclaimer
of rights or other dedication to the public, Chevron will offer to assign such C
Chem patent to Company at Company's expense.

            (f) Upon Closing, Chevron shall and shall cause, if necessary, its
Patent Subsidiaries to grant to the Company the exclusive, irrevocable, royalty
free worldwide right and license, including the right to sublicense, to
practice, make, use and sell under all C Chem Proprietary Technology and C Chem
Patent Rights not otherwise assigned to the Company; PROVIDED, HOWEVER, that
Chevron reserves (1) an irrevocable, nonexclusive royalty free worldwide license
extendible to Chevron's Patent Subsidiaries for use in Chevron's and such Patent
Subsidiaries' own business operations and (2) an irrevocable, nonexclusive
royalty free worldwide right to Chevron, or its designee, to license its
Affiliates or any third party for use in any field other than a field primarily
related to the P Chem or C Chem business without obligation to account to any
other party. Chevron shall and shall cause its Affiliates and third parties to
take appropriate measures to protect the confidentiality of C Chem Proprietary
Technology and to limit its use, which shall be no less stringent than Chevron
takes with respect to its own proprietary technology of the same type and shall
cause its Affiliates and third parties to accept any applicable contractual
restrictions placed on proprietary technology obtained from others.

            (g) The Company shall have (1) an irrevocable, royalty-free
worldwide license under any proprietary technology owned or otherwise licensable
by Chevron or its Patent Subsidiaries not contained in the definition of C Chem
Proprietary Technology and (2) an irrevocable, royalty-free worldwide immunity
from suit under any patent rights which are owned or otherwise licensable by
Chevron or its Patent Subsidiaries not contained within the definition of C Chem
Patent Rights, insofar as, and only insofar as such proprietary technology and
claims of such patent rights cover technology and inventions that are used in
the C Chem or P Chem business as of the Closing Date or which embody technology
or inventions relating to C Chem or P Chem business conceived by the Company or
on its behalf prior to the later of (i) December 31, 2000 or (ii) the six-month
anniversary of the Closing Date, provided such patent rights are based on
applications for patents filed or claiming priority from applications filed
heretofore or hereafter prior to three years after the Closing Date; in each
case subject to the terms and conditions, including the obligation to account to
third parties, under which such rights are held. Such license and immunity from
suit shall be limited to the conduct of the Company's business




                                      -49-


<PAGE>


operations primarily related to the P Chem or C Chem business, including without
limitation research, development, and demonstration activities, the manufacture,
use, or sale of P Chem or C Chem products and the licensing of P Chem or C Chem
technology by the Company, and may be extended by the Company to its Affiliates,
contractors, suppliers, customers and to other third parties, only as
appropriate for the purpose of conducting such P Chem or C Chem business and P
Chem or C Chem licensing operations; PROVIDED, HOWEVER, that no licenses or
immunities will be granted to the Company covering technology and inventions
that are part of Chevron non-C Chem technology licensing packages being offered
as of the date that is the later of December 31, 2000 or the six-month
anniversary of the Closing Date, except under separate agreement by the Company
and Chevron thereto. Company shall and shall cause its Affiliates and third
parties to take appropriate measures to protect the confidentiality of such
proprietary technology and to limit its use as provided above as the Company
takes with respect to its own proprietary technology of the same type and shall
cause its Affiliates and third parties to accept any applicable contractual
restrictions placed on proprietary technology obtained from others.

            (h) Promptly after the later of (i) December 31, 2000 or (ii) the
six-month anniversary of the Closing Date, Chevron shall fully disclose and, if
necessary, shall cause its Patent Subsidiaries to fully disclose and make
available to the Company any and all C Chem Proprietary Technology not
theretofore disclosed and made available to the Company, including any
inventions within the scope of C Chem Patent Rights, and shall cooperate and
cause its personnel to cooperate with the Company or its nominee as may be
reasonably required in order to obtain patent protection therefor.

            (i) The Company's exclusive license granted under subsections (b)
and (f) above and subject to the reservations therein, shall include, without
limitation, the exclusive right to file, prosecute or abandon patent
applications, issue patents, and license third parties under such patent rights
and proprietary technology and the exclusive right to enforce such patents and
proprietary technology rights, including the exclusive discretion to commence,
control and settle any litigation and other proceedings and to recover for past,
present, or future damages and other relief under such patents and proprietary
technology rights; and the licensor shall participate in any such litigation or
proceedings and provide the Company with such information and assistance as
reasonably necessary for such litigation or other proceedings, including
execution of documents and assignment of such patent or proprietary technology
to the Company upon the Company's request and at the Company's cost.

            (j) Phillips and Chevron recognize that each has entered into
numerous agreements with third parties which contain provisions for the transfer
of technology and improvements and for granting licenses and patent rights to
such technology and improvements, and it is the intent of Chevron and Phillips
that such third parties shall not acquire rights pursuant to this Agreement or
at Closing except through separately negotiated contractual provisions with the
Company. Consequently, notwithstanding anything in this Agreement to the
contrary, the Company's licenses and rights to assignment under P Chem Patent
Rights and C Chem Patent Rights and rights to use P Chem Proprietary Technology
and C Chem Proprietary Technology shall not include:

               (i)   the right for the Company to disclose P Chem Proprietary
Technology to any third party or to license or sublicense any third party to use
P Chem




                                      -50-


<PAGE>


Proprietary Technology or to license or sublicense any third party under P Chem
Patent Rights pursuant to contractual obligations entered into or otherwise
existing between Chevron and such third party prior to Closing; and

               (ii)  the right for the Company to disclose C Chem Proprietary
Technology to any third party or to license or sublicense any third party to use
C Chem Proprietary Technology or to license or sublicense any third party under
C Chem Patent Rights pursuant to contractual obligations entered into or
otherwise existing between Phillips and such third party prior to closing;

unless and until the Company after Closing has executed a separate written
agreement with such third party providing for such disclosure, license or
sublicense of proprietary technology or patent rights.

            (k) All registered trademarks, other than Trademarks and Logos,
which are primarily used or identified as relating to the P Chem business as
listed in Schedule 6.18 of the Phillips Disclosure Schedule and to the C Chem
business as listed in Schedule 6.18 of the Chevron Disclosure Schedule and all
foreign counterparts thereof, shall be assigned to the Company at Closing (with
recording of such assignments in the applicable trademark registration issuance
office to occur as soon as practicable after the Closing with the costs of such
assignment to be borne by the Company, subject to such written agreements,
licenses or consents as exist as of the Closing Date.

            Section 6.19 K-Resin Contribution. (a) Phillips shall make a cash
advance to the Company that may be either repaid in part to Phillips or added to
and treated as part of the capital contribution that Phillips and its Affiliates
are making at the Closing, in any case, as set forth in this Section 6.19(a). At
Closing, Phillips shall advance to the Company $70 million, subject to
adjustment depending on the calendar month by which the Company has produced at
the K-Resin Plant (and/or Designated Replacement Facilities) and sold into the
market an aggregate of 143 million pounds of K-Resin, of which at least 114
million pounds must be of prime quality (the "Target Quantities") and subject to
a maximum cap of $109 million. No adjustment shall be due if Target Quantities
are achieved later than November 30, 2001 but prior to the close of business on
December 31, 2001, and in such event the entire advance shall be added to
Phillips' capital contribution to the Company. For each calendar month prior to
December 2001 by which Target Quantities have been achieved, Phillips' advance
shall be repaid by $3.2 million and the balance of the advance shall be treated
as a capital contribution to the Company. If it is determined that the Target
Quantities have not been achieved by December 31, 2001, then the entire advance
shall be treated as a capital contribution to the Company and, on the tenth
business day of each calendar month after December 2001 until Target Quantities
have been achieved, Phillips shall make an additional capital contribution of
$3.2 million to the Company; provided that no contribution will be due after
December 2002 even if Target Quantities have not been achieved by December 31,
2002.

            (b) In addition to the capital contribution set forth in
Section 6.19(a), Phillips shall make a capital contribution to the Company equal
in amount to the tax-adjusted shortfall (the "Tax-Adjusted Shortfall") from the
Projected K-Resin EBITDA for the period commencing on the Closing Date and
ending on the earlier of (i) December 31, 2002 or (ii) six months after




                                      -51-


<PAGE>


production capacity equal to 370 million pounds per year has been restored at
the K-Resin Plant (the "Cut-Off Date"), subject to a maximum cap of $30 million.
The amount of Phillips' contribution pursuant to this Section 6.19(b) shall be
determined as soon as practicable after the Cut-Off Date, and any contribution
which is then due shall be made within three business days of such
determination. However, no capital contribution will be due unless there is a
cumulative EBITDA shortfall at the end of the period. The "Tax-Adjusted
Shortfall" is an amount equal to the product of (i) the applicable cumulative
EBITDA shortfall and (ii) the excess of 100% over the applicable Tax Rate (as
defined in the Amended LLC Agreement). The "Tax-Adjusted Shortfall" shall be
determined after giving effect to the provisions contained below in Section
6.19(e).

            (c) The Parties intend that the capital contributions set forth in
Sections 6.19(a) and 6.19(b) above are intended to be capital contributions to
the Company and not taxable income to the Company or its members. In furtherance
of this intent, Phillips shall indemnify Chevron and the Class C Members of the
Company on a Net After-Tax Basis against any income or franchise tax incurred in
the event that any such capital contribution is treated as taxable income.
Phillips shall indemnify Chevron and the Class C Members of the Company on a Net
After-Tax Basis against any income or franchise tax in the event that there is a
disguised sale under section 707(a)(2)(B) of the Internal Revenue Code or
corresponding provision of state or local law by Chevron or any Class C Member
that would not have occurred but for Phillips capital contributions in Sections
6.19(a) and 6.19(b) and any related distribution to Chevron or any Class C
Member or payment of a liability by the Company or any of its Subsidiaries,
provided, however, that in each case the terms and conditions of the Amended LLC
Agreement have been complied with.

            (d) Phillips shall, by assignment or other means, take appropriate
steps to ensure that the Company promptly receives, for the period following the
Closing, the benefits of and proceeds (the "BI Insurance Proceeds") from any
insurance policy for losses from business interruption ("BI Insurance Policy")
due to the K-Resin Accident.

            (e) The Company shall have the economic benefit of any BI Insurance
Policy and any BI Insurance Proceeds and shall include such proceeds in the
calculation of its taxable income for federal income tax purposes, and Phillips
shall have no indemnity obligation with respect to any such income. When
actually received by the Company, such proceeds will be credited toward the
K-Resin Plant EBITDA. The amount credited toward the K-Resin Plant EBITDA will
be equal to 100% of the amount of the BI Insurance Proceeds unless it is
determined by a Final Determination with respect to the Company or Phillips that
the Company should not include such proceeds in the calculation of its taxable
income for federal income tax purposes then the amount credited towards the
K-Resin Plant EBITDA shall be equal to the product of the amount of such
proceeds and a fraction (expressed as a percent), the numerator of which is 100
and the denominator of which is 100 minus the Tax Rate. In the event that the
Company receives the BI Insurance Proceeds and it is so determined that the
Company should not include such proceeds in the calculation of its taxable
income for federal income tax purposes, the Company shall refund to Phillips an
amount equal to the product of (i) the BI Insurance Proceeds and (ii) the Tax
Rate. Phillips, as a member of the Company and on behalf of the Company, will
have sole and exclusive authority to manage any recovery under a BI




                                      -52-



<PAGE>

Insurance Policy, and the Company will cooperate fully with Phillips in making
and establishing claims and in seeking to maximize recovery under the BI
Insurance Policies.

            Section 8.1  Termination.  This Agreement may be terminated at any
time prior to the Closing by:

            (b) the mutual written consent of Phillips and Chevron;

            (c) either Phillips or Chevron if the Closing has not occurred by
the close of business on September 30, 2000; PROVIDED, HOWEVER, that the failure
to consummate the transactions contemplated by this Agreement did not result
from the failure by the party seeking termination of this Agreement to fulfill
any material undertaking or commitment provided for herein that is required to
be fulfilled prior to the Closing;

            (d) either Phillips or Chevron if the other Party shall have
breached or failed to perform in any material respect any of its respective
representations, warranties, covenants or other agreements contained in this
Agreement, which breach or failure to perform (i) would give rise to the failure
of a condition set forth in Section 7.1(a) or 7.2(a), as applicable, and (ii)
cannot be or has not been cured within 30 days after the giving of written
notice to Phillips or Chevron, as applicable; or

            (e) either Phillips or Chevron in the event that any order, law,
statute, ordinance, rule, regulation or decree becomes effective (and final and
nonappealable), permanently restraining, enjoining or otherwise prohibiting or
making illegal or otherwise prohibiting the consummation of a material portion
of the transactions contemplated by this Agreement or the Amended LLC Agreement,

            (b) Subject to the provisions of this Article IX, Chevron shall

and (ii) any failure by Chevron to perform any covenant or agreement hereunder.

            (c) Matters relating to indemnification for Taxes shall not be
governed by this Article IX (other than this Section 9.2(c)), except to the
extent otherwise provided in Annex B. The parties hereto agree that the
indemnification provisions in Annex B shall be the exclusive remedy of the
parties with respect to breaches of the representations and warranties in
Sections 6.1 and 6.2 of Annex B, except for actions grounded in fraud, with
respect to which the remedies and limitations set forth in this Agreement shall
not apply or in any manner limit the scope or availability of any other remedy
at law or in equity.

            Section 9.3 Indemnification Procedure. All claims by any Indemnified

Notwithstanding the foregoing, any covenants or agreements contained in this

            Section 9.5 Indemnification Limitation. (a) Each Indemnified Party

or otherwise.

            (b) Phillips' obligation to indemnify Chevron and its Affiliates

shall have exceeded the Basket. If the aggregate amount of Damages sustained by
Chevron and its Affiliates and the Company and its Affiliates as described in
Section 9.2(a)(i) exceeds the Basket, then Chevron and its Affiliates and the
Company and its Affiliates shall be entitled to assert claims under this Article
IX for indemnification for the amount of such Damages in excess of the Basket
only; PROVIDED that Phillips' obligation with respect to indemnification under
Section 9.2(a)(i) shall not exceed the Cap in the aggregate.

            (c) Chevron's obligation to indemnify Phillips and its Affiliates
and the Company and its Affiliates as provided in Section 9.2(b)(i) shall not
become effective until the aggregate of all Damages sustained by Phillips and

9.2(b)(i) shall have exceeded the Basket. If the aggregate amount of Damages
sustained by Phillips and its Affiliates and the Company and its Affiliates as
described in Section 9.2(b)(i) exceeds the Basket, then Phillips and its
Affiliates and the Company and its Affiliates shall be entitled to assert claims
under this Article IX for indemnification for the amount of such Damages in
excess of the Basket only; PROVIDED that Chevron's obligation with respect to
indemnification under Section 9.2(b)(i) shall not exceed the Cap in the

Company or their respective Affiliates shall be entitled to assert claims for
indemnification under this Article IX unless the aggregate amount of Damages
claimed in any individual Claim Notice exceeds $2,000,000 in the aggregate.

            (e) For avoidance of doubt, the indemnification provisions set forth

any manner limit the scope or availability of any other remedy at law or in

deemed to be true to the extent the breach thereof is reasonably attributable to

operate (including chemicals price levels), to general economic conditions in
the United States (including prevailing interest rate and stock market levels,)
or to the transactions contemplated by this Agreement or the Amended LLC
Agreement.

            Section 9.7 Knowledge Qualifiers. For purposes of determining
Damages and rights to indemnification under this Article IX, the representations
and warranties set forth in Sections 4.5 and 5.5 shall be read without giving

Trial. (a) This Agreement shall be governed by and construed in accordance with
the laws of the State of Delaware without reference to the choice of law
principles thereof.

in any action arising out of or




                                      -58-


<PAGE>


relating to this Agreement, and hereby irrevocably agrees that all claims in
respect of such action may be heard and determined in such Delaware state or
federal court. Each party hereto hereby irrevocably waives, to the fullest
extent it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding. The parties hereto further agree, to
the extent permitted by law, that final and unappealable judgment against any of
them in any action or proceeding contemplated above shall be conclusive and may
be enforced in any other jurisdiction within or outside the United States by

the fact and amount of such judgment.

            (c) To the extent that any party hereto has or hereafter may acquire
any immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, each
party hereto hereby irrevocably waives such immunity in respect of its
obligations with respect to this Agreement.

            (d) Each party hereto waives, to the fullest extent permitted by
applicable laws, any right it may have to a trial by jury in respect of any
action, suit or proceeding arising out of or relating to this Agreement. Each
party hereto certifies that it has been induced to enter into this Agreement by,

agreement between the parties with respect to the subject matter hereof, and
there are no agreements, understandings, representations or warranties between
the parties other than those set forth or referred to herein. Except for Annex C
hereto and Articles IX and XI, which are intended to benefit, and to be

intended to confer upon any Person not a party hereto (and their successors and
assigns) any rights or remedies hereunder.

whether or not the transactions contemplated in this Agreement or the Amended
LLC Agreement are consummated, all legal and other costs and expenses incurred
in connection with this Agreement and the Amended LLC Agreement and the

                                  ARTICLE III

                                  COMPENSATION

            Section 3.1   Compensation Generally. Without limiting the scope of
Section 2.3, except as provided in the following sentence and in Section 3.2,
Phillips or Chevron or their respective Subsidiaries, as applicable, shall
retain all liability and responsibility for wages, salary, overtime pay,
bonuses, incentive pay, and other cash compensation of P Chem Employees and C
Chem Employees attributable to periods before the Transfer Date. Effective as of
the Transfer Date, the Company and its Subsidiaries shall assume and be solely
responsible for (a) all accrued but unused vacation and sick leave entitlements
of Transferred Employees


<PAGE>


attributable to periods before the Transfer Date and (b) all wages, salary,
overtime pay, bonuses, incentive pay, vacation pay, sick pay and other cash
compensation of Transferred Employees attributable to the period beginning on
the Transfer Date. From and after the Transfer Date, the Company shall provide
to Transferred Employees all wages, salary, overtime pay, bonuses, vacation pay,
sick pay, other cash compensation and cash and equity-based incentive
compensation on such terms as may be determined from time to time by the Company
in its sole discretion.

            Section 3.2   Incentive Compensation. If the Transfer Date is on or
before December 31, 2000, Phillips and Chevron shall determine the amounts of
the annual bonuses (the "Bonuses") earned by Transferred Employees for the year
2000 under its bonus plans, and the Company shall reimburse Phillips (in the
case of Transferred P Chem Employees) and Chevron (in the case of Transferred C
Chem Employees) for a pro-rata portion of the Bonuses, based upon the number of
days in such year after the Transfer Date. Such reimbursement shall be net of
the employer's share of any employment taxes relating to such pro-rata Bonuses
for the period before the Transfer Date and required to be paid by the Company
or any of its Subsidiaries. Nothing contained herein shall preclude Phillips or
Chevron from designating the Company as an "affiliate" under their respective
stock option and incentive plans for purposes of continued vesting, exercise and
payouts under their respective stock option and incentive plans.

            Section 3.3   Indemnification and Reimbursement. Notwithstanding
anything to the contrary in this Annex, the Company shall indemnify Phillips and
Chevron, respectively, for all employment-related liabilities and Termination
Costs of P Chem Employees and C Chem Employees incurred during the period
beginning on the Closing Date and continuing through the Transfer Date, and
shall reimburse Phillips and Chevron, respectively, for all employment-related
expenses of P Chem Employees and C Chem Employees incurred during the period
beginning on the Closing Date and continuing through the Transfer Date, through
the provisions of the Transition Services Agreement.

                                   ARTICLE IV

                                EMPLOYEE BENEFITS

            Section 4.1   Employee Benefits Generally. (a) Effective as of the
Transfer Date, except as provided in Section 4.2(b), the Transferred Employees
shall cease to be active participants in the Parent Plans. Effective as of the
Closing Date, neither the Company nor any of its Subsidiaries shall be a
participating employer in any Parent Plan. Phillips and Chevron shall remain
solely responsible for all liabilities with respect to the Phillips Plans and
the Chevron Plans, respectively, and the Company and its Subsidiaries shall not
assume any Parent Plan and shall have no obligations and shall assume no
liabilities with respect to the Parent Plans, in each case except as
specifically provided in Section 4.2(b) and Section 4.5(d) below.

            (b) From and after the Transfer Date, the Company and its
Subsidiaries shall be solely responsible for providing Transferred Employees
with employee benefits, including without limitation welfare, savings and
pension benefits, which shall be designed by the Company in its sole discretion.
Phillips and Chevron shall provide the Company and its Subsidiaries with all
necessary transition assistance to enable them to develop and implement


<PAGE>


their compensation and benefit plans and programs. The Company and its
Subsidiaries shall provide compensation and benefits to Transferred Employees
sufficient such that neither Phillips (and its Subsidiaries), nor Chevron (and
its Subsidiaries), shall incur any Severance Costs with respect to the
Transferred Employees. If the Company (or its Subsidiaries) offers employment to
any Employee whose Severance Costs were reimbursed pursuant to Section 2.3 the
Company (or its Subsidiary) may, as a condition to the acceptance of such offer,
require the Employee to repay the amount of such reimbursement.

            (c) For purposes of eligibility to participate and vesting under all
compensation and benefit plans applicable to Transferred Employees on or after
the Transfer Date, the Company and its Subsidiaries shall give Transferred
Employees credit for all applicable service with Phillips and its Subsidiaries
(including the P Chem Subsidiaries), or Chevron and its Subsidiaries (including
the C Chem Subsidiaries), as applicable, before the Transfer Date. For these
purposes, the applicable service for a Transferred P Chem Employee shall be
determined by the elapsed time since his or her Service Award Entry Date as
recorded in the personnel records of Phillips.

            Section 4.2   Severance Benefits. The Company and its Subsidiaries
shall provide to each Transferred P Chem Employee and each Transferred C Chem
Employee whose employment terminates on or before the first anniversary of the
Closing Date cash severance benefits at least equal to the greater of the
applicable Severance Amount and the applicable Required Severance Amount,
subject to the execution by such Transferred P Chem Employee or Transferred C
Chem Employee of a Release.

            Section 4.3   Pension Benefits. Effective as of the Transfer Date,
Phillips shall cause the Transferred P Chem Employees to be 100% vested in their
accrued benefit under the Retirement Income Plan of Phillips Petroleum Company
and any nonqualified excess plan associated with such plan (collectively, the
"Phillips RIP") as required by the terms thereof, and Chevron shall cause the
Transferred C Chem Employees to be 100% vested in their accrued benefit under
the Chevron Corporation Retirement Plan and any nonqualified excess plan
associated with such plan (collectively, the "Chevron RP"). The Company shall
establish a retirement plan for the Transferred Employees. In no event shall the
benefit provided under the Company's retirement plan (expressed as a life
annuity commencing at age 65), be less than the benefit the Transferred
Employees would have obtained under the Phillips RIP or the Chevron RP, as
applicable, taking into account only service with Phillips or Chevron, as
applicable, prior to the Transfer Date and the final average pay from the
Company and its Subsidiaries, reduced by the benefit actually accrued under the
Phillips RIP or the Chevron RP, as applicable.

            Section 4.4   Savings Plans. (a) Effective as of the Transfer Date,
Phillips shall cause the Transferred P Chem Employees to be 100% vested in their
accrued benefit under the Phillips Savings Plans, and Chevron shall cause the
Transferred C Chem Employees to be 100% vested in their accrued benefits under
the Chevron Savings Plan.

            (b) The Company, Phillips and Chevron shall take all reasonable
steps necessary and appropriate so that Transferred Employees who participated
in the Phillips Savings Plans or the Chevron Savings Plan, as applicable, and
who have loans outstanding from


<PAGE>


any such plan as of the Transfer Date may continue to repay such loans using
voluntary payroll deductions from their paychecks from the Company and its
Subsidiaries.

            Section 4.5   Welfare Benefits. Without limiting the generality of
the above provisions, this Section 4.5 contains certain specific provisions
regarding the provision of benefits under Welfare Benefit Plans, unemployment
compensation benefits and workers compensation benefits.

            (a) Effective as of the Transfer Date, the Company shall cause the
Transferred Employees to be eligible to be covered by such Welfare Benefit Plans
sponsored by the Company and/or one or more of its Subsidiaries as the Company
shall determine to implement.

            (b) Except as specifically provided in Section 4.5(d) below: (i)
Phillips and its Subsidiaries shall be solely responsible for (A) claims of
Transferred P Chem Employees and their eligible beneficiaries and dependents for
workers compensation, unemployment compensation and under Welfare Benefit Plans
that are incurred before the Transfer Date, and (B) claims relating to COBRA
Coverage attributable to "qualifying events" occurring on or before the Transfer
Date with respect to any Transferred P Chem Employees and their eligible
beneficiaries and dependents; (ii) Chevron and its Subsidiaries shall be solely
responsible for (I) claims of Transferred C Chem Employees and their eligible
beneficiaries and dependents for workers compensation, unemployment compensation
and under Welfare Benefit Plans that are incurred before the Transfer Date, and
(II) claims relating to COBRA Coverage attributable to "qualifying events"
occurring on or before the Transfer Date with respect to any Transferred C Chem
Employees and their eligible beneficiaries and dependents; and (iii) the Company
and its Subsidiaries shall be solely responsible for (x) claims of Transferred
Employees and their eligible beneficiaries and dependents for workers
compensation and unemployment compensation benefits and claims under Welfare
Benefit Plans that are incurred on or after the Transfer Date, and (y) claims
relating to COBRA Coverage attributable to "qualifying events" occurring after
the Transfer Date with respect to Transferred Employees and their beneficiaries
and dependents. A medical/dental claim shall be considered incurred on the date
when the medical services are rendered or medical supplies are provided, and not
when the condition arose or when the course of treatment began. An unemployment
compensation or workers compensation claim shall be considered incurred before
the Transfer Date if the occurrence leading up to the claim occurs before the
Transfer Date.

            (c) Each Transferred Employee who is employed in an eligible job
classification shall be immediately eligible to participate, without any waiting
time, in any and all Welfare Benefit Plans sponsored by the Company and its
Subsidiaries for the benefit of Transferred Employees (such plans, collectively,
the "New Welfare Plans") to the extent coverage under such New Welfare Plan
replaces coverage under a similar Phillips Plan or Chevron Plan, in which such
Transferred Employee was previously eligible to participate (such plans,
collectively, the "Old Welfare Plans"). For purposes of each New Welfare Plan
providing medical, dental, pharmaceutical and/or vision benefits, the Company
shall cause all pre-existing condition exclusions and actively-at-work
requirements of such New Welfare Plan to be waived for Transferred Employees and
their eligible beneficiaries and dependents, to the extent such exclusions and
restrictions did not apply under the applicable Old Welfare Plan, and the
Company shall cause any Eligible Expenses incurred by any Transferred Employee
and his or


<PAGE>


her eligible beneficiaries and dependents during the portion of the plan year of
the Old Welfare Plan ending on the Transfer Date, to be taken into account under
such New Welfare Plan for purposes of satisfying all deductible, coinsurance and
maximum out-of-pocket requirements applicable to such Transferred Employee and
his or her eligible beneficiaries and dependents for the applicable plan year as
if such amounts had been paid in accordance with such New Welfare Plan.

            (d) The Company shall establish one or more flexible spending plans
(collectively, the "New FSP") in which Transferred Employees shall be eligible
to participate following the Transfer Date. Phillips, Chevron and the Company
shall take all reasonable steps necessary or appropriate so that the account
balances under the Phillips FSP or the Chevron DCP, as applicable, of each
Transferred Employee who has elected to participate therein in the year in which
the Transfer Date occurs shall be transferred, as soon as practicable after the
Transfer Date, from the Phillips FSP or the Chevron DCP, as applicable, to the
New FSP, and so that the contribution elections of each such Transferred
Employee as in effect immediately before the Transfer Date remain in effect
under the New FSP immediately after the transfer of such account balance. If the
aggregate amount of the transferred account balances of Transferred P Chem
Employees or Transferred C Chem Employees is negative, then the Company shall
pay Phillips or Chevron, as applicable, the amount of such aggregate negative
balance promptly following such account balance transfer. Notwithstanding the
provisions of Section 4.5(b), from and after the date a Transferred Employee's
FSP account is transferred in accordance with this Section 4.5(d), the Company
shall be solely responsible for, and shall satisfy from the New FSP, all claims,
whether incurred before, on or after the Transfer Date, for which such
Transferred Employee was entitled to seek reimbursement under the Phillips FSP
or the Chevron DCP for the year in which the Transfer Date occurs.

                                  TAX BENEFITS

            Section 5.1   Tax Benefits Generally. It is the intention of
Phillips, Chevron and the Company that any tax deductions or other tax benefits
associated with any compensation or benefits payable to P Chem Employees and C
Chem Employees by any of them be enjoyed by the party that bears the economic
cost thereof, whether through direct payment or provision of such compensation
or benefits or through reimbursement, and they agree to cooperate to ensure such
result to the greatest extent possible, through allocation of partnership
deductions, adjustment of the amounts of any reimbursement or otherwise.

                                   ARTICLE VI

                                FOREIGN BENEFITS

in this Annex to the contrary, the Company may adopt or maintain compensation
and benefit plans and programs of Phillips and/or Chevron in Puerto Rico and
locations outside the United States, where appropriate and agreed by both
Phillips and Chevron (but not including any equity-based plans).

          Section 2.4  Limitation on Tax Indemnities.

          (a) As provided in Section 9.2(c) of the Contribution Agreement, the
indemnification provided in Sections 2.1, 2.2 and 2.3 shall not be subject to
the limitations set forth in Section 9.5 of the Contribution Agreement except as
otherwise set forth herein.

          (b) Chevron's indemnification obligations under Section 2.1(b) shall
not become effective until, and no claims for indemnification under this Article
II may be asserted unless, the aggregate amount of Taxes subject to
indemnification under Section 2.1(b) (determined without regard to this Section
2.4(b)) exceeds the Tax Basket Amount and, if the aggregate amount of Taxes so
determined exceeds the Tax Basket Amount, then Phillips and the Company shall be
entitled to assert claims under this Article II for indemnification for the
amount in excess of the Tax Basket Amount only; provided, that the obligation
with respect to indemnification under Article II hereof shall be subject to, and
included in determining, the Cap. For the avoidance of doubt, Taxes referred to

indemnification under Section 2.2.

          (d) The amount of any indemnification pursuant to Section 2.1 or
2.2 shall be reduced to the extent both the amount was accrued as a liability

December 31 Balance, as the case may be, and




                                      -4-

Capital or Chevron's Actual Net Working Capital under Section 3.3 of the
Contribution Agreement, as the case may be.

Indemnifying Party") shall be required to make any indemnity payments to a party
seeking payments (a "Tax Indemnified Party") pursuant to Article II until there
occurs a Final Determination of the liability for which indemnification is
sought. Any such payment to a Tax Indemnified Party shall be made not later than
twenty (20) business days after receipt by the Tax Indemnifying Party of written
notice of such Final Determination together with written notice from the Tax
Indemnified Party stating that any payment for which the Tax Indemnified Party
is to be indemnified pursuant to Article II has been paid by the Tax Indemnified
Party, the payment requested and documentation reasonably establishing payment
of the amount sought to be indemnified. If at any time prior to a Final
Determination a party controlling a Tax Proceeding pursuant to Section 3.1(a) or
(b) hereof elects to pay a Tax and to pursue a claim for refund of such Tax, the
party controlling the Tax Proceeding shall have sole responsibility for the
payment of such Tax and shall be entitled to any refund thereof. The obligations
and rights set forth in the preceding sentence are independent from, and not in
limitation of, the obligations and rights set forth in the first two sentences
of this Section 2.4(e) and the other provisions of Article II.

Schedule, as the case may be.

          (g) Notwithstanding any other provision of this Article II, (i) in
the case of a breach of a warranty or representation set forth in Section 6.1,
the amount subject to indemnification under Section 2.1(a) or 2.1(b) shall be
the incremental amount of Taxes incurred by the Company, its Subsidiaries and
the Phillips Group in the aggregate that would not have been incurred but for
such breach of warranty or representation, and (ii) in the case of a breach of a
warranty or representation set forth in Section 6.2, the amount subject to
indemnification under Section 2.2(a) or 2.2(b) shall be the incremental amount
of Taxes incurred by the Company, its Subsidiaries and the Chevron Group in the
aggregate that would not have been incurred but for such breach of warranty or
representation.

          (h) To the extent not inconsistent with any provisions of this Tax
Matters Annex, Article III of Annex C to the Contribution Agreement, governing
Dispute Resolution Procedure, shall be incorporated into this Tax Matters Annex.

                                  ARTICLE III

                                 TAX PROCEDURES

                                      -5-


<PAGE>


          (a) Chevron shall be entitled to control in all respects, including
with respect to settlement, any Tax Proceeding with respect to any Tax if
Chevron would have an indemnity obligation with respect to such Tax under
Section 2.1 and the resolution of the Tax will not result in any
non-indemnifiable liability for the Company. None of the Company or its
Subsidiaries and Phillips and its Subsidiaries shall be entitled to participate
in any such Tax Proceeding.

          (b) Phillips shall be entitled to control in all respects, including
with respect to settlement, any Tax Proceeding with respect to any Tax if
Phillips would have an indemnity obligation with respect to such Tax under
Section 2.2 and the resolution of the Tax will not result in any
non-indemnifiable liability for the Company. None of the Company or its
Subsidiaries and Chevron and its Subsidiaries shall be entitled to participate
in any such Tax Proceeding.

          (c) if (i) neither Chevron nor Phillips is entitled to control a Tax
Proceeding because the Tax which is the subject of the Tax Proceeding is both an
indemnifiable Tax and a non-indemnifiable Tax or (ii) the party entitled to
control a Tax Proceeding elects not to control such Tax Proceeding or fails to
do so, the Tax Matters Partner, acting in accordance with Section 9.6 of the
Amended LLC Agreement, shall control such Tax Proceeding.

          Section 3.2  Allocation of Certain Taxes.

          (a) If a Chevron Acquired Entity or a Phillips Acquired Entity (each
an "Acquired Entity") is permitted but not required under applicable state,
local or foreign Income Tax laws to treat the Closing Date as the last day of a
taxable period, then the parties shall cause such Acquired Entity to treat that
day as the last day of a taxable period.

          (b) In the case of Income Taxes and other taxes based upon income or
receipts arising in a taxable period of a Chevron Acquired Entity or a Phillips
Acquired Entity that includes but does not end on the Closing Date, except as
provided in Section 3.2(c), the allocation of such Taxes between the Pre-Closing
Period and the Post-Closing Period shall be made on the basis of an interim
closing of the books as of the end of the Closing Date. For the avoidance of
doubt, for purposes of this Section 3.2(b), the taxable year of each Acquired
Entity that is a partnership or "flowthrough" entity, shall be treated as if it
ended at the close of business on the Closing date and Taxes attributable to the
income and gain of such entities through the close of business on the Closing
date shall be treated as Pre-Closing Period Taxes.

          (c) In the case of (i) property Taxes and other taxes that are not
based upon income or receipts and (ii) AD VALOREM Taxes, in either case
attributable to any taxable period that includes but does not end on the Closing
Date, the portion of such Taxes attributable to the Pre-Closing Period shall be
the amount of such Taxes for the entire taxable period, multiplied by a fraction
the numerator of which is the number of calendar days in such taxable period
ending on and including the Closing Date and the denominator of which is the
entire number of calendar days in such taxable period, and the balance of such
Taxes shall be attributable to the Post-Closing Period.

for any Pre-Closing Period, without the prior written consent of Chevron, in the
case of any such Tax Return that could affect the indemnification obligations of
Chevron under this Annex or any Taxes for which Chevron is otherwise
responsible, or Phillips, in the case of any such Tax Return that could affect
the indemnification obligations of Phillips under this Annex or any Taxes for
which Phillips is otherwise responsible.

          Section 3.4   Cooperation and Exchange of Information. Chevron,
Phillips and the Company shall (and each shall cause its respective Subsidiaries
to) cooperate with one another with respect to Tax matters. As soon as
practicable, but in any event within 30 days after the request of Chevron,
Phillips or the Company, from and after the Closing Date, the Company shall
deliver to Chevron or Phillips, respectively, and Chevron or Phillips, as the
case may be, shall deliver to the Company, such information and data and make

received from or sent to any Governmental Entity that relate to the Company and

related workpapers, documents relating to rulings or other determinations by any

respective Subsidiaries to) make its employees and facilities available on a
mutually convenient basis to provide explanation of any documents or information
