     Section 3.01. Claims for Benefits. Any claim relating to benefits under

<PAGE>   9
the Compensation Committee determines that any claimant is not entitled to
receive all or part of the benefits claimed, it will mail or deliver written
notice to such claimant of (a) its determination and the reasons therefor, with
appropriate references to pertinent Plan provisions, and (b) the procedure for
review of its determination. Such notice shall, if appropriate, also explain how
a claimant may perfect the claim and why submission of additional information is
necessary to do so. Such notice shall be provided within 90 days after
submission of the claim. If the claimant does not receive notice of a decision
within such 90-day period, the claimant's claim shall be deemed denied.

     Section 3.02. Administrative Appeal. An applicant for benefits whose claim
has been denied in whole or in part, or the duly authorized representative of
such claimant, may, within 60 days after receipt of written notice of such
denial (or after the claim is deemed denied), request a review thereof and
submit to the Compensation Committee in writing such additional information as
the claimant desires. A claimant who submits a claim for review shall have a
reasonable opportunity to submit issues and comments in writing and to review
pertinent documents. The Compensation Committee will then render its final
decision with the specific reasons therefore (including references to pertinent
Plan provisions) and notify the claimant in writing of such decision within 60
days after the submission of such request for review. If the claimant does not
receive notice of such decision within such 60-day period, the claim for review
shall be deemed denied.

     Section 3.03. Negotiation. Subject to Section 3.05, in case a dispute or
controversy shall arise between any Participant (or any person claiming by,
through or under any Participant) and the Company (including the Compensation
Committee) relating to or arising out of this Plan or a benefit claim for which
a final administrative appeal has been denied (or deemed denied) pursuant to
Section 3.02, either disputant may give written notice to the other disputant
("Dispute Notice") that it wishes to resolve such dispute or controversy by
negotiations, in which event the disputants shall attempt in good faith to
negotiate a resolution of such dispute or controversy. If the dispute or
controversy is not so resolved within 30 days after the effective date of the
Dispute Notice, subject to Section 3.05, either disputant may initiate
arbitration of the matter as provided in Section 3.04. All negotiations pursuant
to this Section 3.03 shall be held at the Company's principal offices in
Houston, Texas (or such other place as the disputants shall mutually agree) and
shall be treated as compromise and settlement negotiations for the purposes of
the federal and state rules of evidence and procedure.

     Section 3.04. Arbitration. Subject to Section 3.05, any dispute or
controversy (a) which arises out of or relates to this Plan or a benefit claim
for which a final administrative appeal has been denied (or deemed denied)
pursuant to Section 3.02 and (b) which has not been resolved by negotiations in
accordance with Section 3.03 within 30 days of the effective date of the Dispute
Notice shall, upon the request of either disputant, be finally settled by
arbitration conducted expeditiously in accordance with the labor arbitration
rules of the American Arbitration Association. The arbitrator shall be not
empowered to award damages in excess of compensatory damages and each disputant
shall be deemed to have irrevocably waived any damages in excess of compensatory
damages. The arbitrator's decision shall be final and legally binding on the
disputants and their successors and assigns. The fees and expenses of the

                                      -9-

<PAGE>   10

arbitrator shall be borne solely by the prevailing disputant or, in the event
there is no clear prevailing disputant, as the arbitrator deems appropriate. All
arbitration conferences and hearings shall be held in Houston, Texas.

     Section 3.05. Exclusivity, etc. The dispute resolution procedures set forth
in Sections 3.03 and 3.04 shall not apply to any matter which, by the express
provisions of this Plan, is to be finally determined by the Compensation
Committee or by an accounting firm or employee benefits firm unless and until
the Compensation Committee, accounting firm or employee benefits firm issues its
decision (in the case of the Compensation Committee, in accordance with Sections
3.01 and 3.02). Any such determination by the Compensation Committee or an
accounting firm or employee benefits firm shall be final and may not be
overturned unless such determination is found to be arbitrary and capricious or
an abuse of discretion. No legal action may be brought with respect to this Plan
except for the purpose of specifically enforcing the provisions of this Article
III or for the purpose of enforcing any arbitration award made pursuant to
Section 3.04.

respects the rights and obligations of all parties with an interest in this
Plan, given the powers, rights and duties specifically stated elsewhere in this
Plan and, in addition, is given full power and final discretionary authority to:

          (i) make determinations with respect to the administration of this
     Plan, construe and interpret its provisions, take all other actions deemed
     necessary or advisable for the proper administration of this Plan and
     determine all questions arising under this Plan, including the power to
     determine the rights or eligibility of Participants and any other persons,
     and the amounts of their benefits under this Plan, and to remedy
     ambiguities, inconsistencies or omissions;

     may be necessary for the proper and efficient administration of this Plan;

          (iii) enforce this Plan in accordance with its terms and in accordance
     with any rules of procedure and regulations adopted by the Compensation
     Committee pursuant to clause (ii) above; and

          (iv) employ agents, attorneys, accountants or other persons (who also
     may be employed by the Company), and allocate, delegate or reallocate to
     them such powers, rights and duties as the Compensation Committee may
     consider necessary or advisable to properly carry out the administration of
     this Plan; provided, however, that such allocation or delegation and the
     acceptance thereof by such agents, attorneys, accountants or other persons
     are in writing.

     (b) Subject to applicable law, any determination, construction or
interpretation of the provisions of this Plan, and any decision on any matter
within the discretion of the Compensation Committee, that is made by the
Compensation Committee in good faith shall be binding on all persons. In case of
any claim that the Compensation Committee (or any member thereof) did not act in
good faith, the burden of proof shall rest with the person or entity claiming
the absence of good faith.

compensation for their services relating to this Plan. Any expenses properly
incurred by the Compensation Committee incident to this Plan, including the cost

     (d) The Company shall indemnify and hold harmless each member of the
Compensation Committee against and all expenses and liabilities arising out of
his or her administrative functions or fiduciary responsibilities, including any
expenses and liabilities that are caused by or result from an act or omission
constituting the negligence of such member in the performance of such functions
or responsibilities, but excluding expenses and liabilities that are caused by
or result from such member's own gross negligence or willful misconduct.
Expenses against which such member shall be indemnified hereunder shall include,
without limitation, the amounts of any settlement or judgment, costs, counsel
fees and related charges reasonably incurred in connection with a claim asserted
or a proceeding brought or settlement thereof.

     Section 4.05. Release of Claims. As a condition to receipt of the benefits
under this Plan, a Participant will be required to sign an agreement, to be
prepared by Holdings, in which he or she unconditionally and irrevocably
releases the Company and its successors, assigns, divisions, subsidiaries,
representatives, agents, officers, directors, stockholders and employees from
any claims, demands and causes of action relating to or arising out of the
termination of his or her employment with the Company, including any statutory
claims under the Age Discrimination in Employment Act of 1967, the Americans
with Disabilities Act of 1990, the Civil Rights Acts of 1964 and 1991 and the

demands and causes of action pertaining to (a) any benefits that are to be
provided after the date of such agreement pursuant to the terms of this Plan,

Key Employee Protection Plan (as the same may hereafter be amended or modified

any employment agreement between such Participant and the Company.

     Section 4.06. Assignability. The Company shall have the right to assign
this Plan and to delegate its duties and obligations hereunder, but not
otherwise; provided, however, that no such assignment shall relieve or discharge
the Company of or from any of its obligations under this Plan. Unless otherwise
approved by the Compensation Committee, no Participant shall transfer or assign
any of his or her rights under this Plan except by will or the laws of descent
and distribution. Except as otherwise provided by law, no benefit, right or
interest of any Participant under this Plan shall be subject to pledge,
encumbrance or charge, seizure, attachment or legal, equitable or other process,
or be liable for, or subject to, debts, liabilities or other obligations.

     Section 4.07. Consolidations, Mergers, Etc. Each of Holdings and Chemicals
will require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of its business,
operations or assets to expressly assume and agree to perform this Plan in
writing, in the same manner and to the same extent that Holdings or Chemicals,
as the case may be, would be required to perform hereunder if no such succession
had taken place.

     Section 4.08. Benefit and Burden. This Plan shall be binding upon and inure
to the benefit of the Company and its successors and assigns. This Plan and all
rights of each Participant shall inure to the benefit of and be enforceable by

personal or legal representatives, executors, administrators, heirs and
permitted assigns. If any Participant should die while any amounts are due and
payable to such Participant hereunder, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Plan to such
Participant's devisees, legatees or other designees or, if there be no such
devisees, legatees or other designees, to such Participant's estate.

     Section 4.09. Notices. All notices and other communications provided for in
this Plan shall be in writing and shall be sent, delivered or mailed, addressed
(a) if to Holdings, Chemicals or any other Subsidiary, at Holdings' principal
office address or such other address as Holdings may have designated by written
notice to all Participants for purposes hereof, directed to the attention of the
Treasurer, and (b) if to any Participant, at his or her residence address on the
records of Holdings or to such other address as he or she may have designated to
Holdings in writing for purposes hereof. Each such notice or other communication
shall be deemed to have been duly given or mailed by United States registered
mail, return receipt requested, postage prepaid, except that any change of
notice address shall be effective only upon receipt.

     Section 4.10. Withholdings. The Company shall have the right to deduct from
any payment hereunder all taxes (federal, state or other) and other payments
which it is required to withhold therefrom.

     Section 4.11. No Employment Rights Conferred. Nothing contained in this
Plan shall (i) confer upon any Participant any right with respect to
continuation of employment with the Company or (ii) subject to the rights and
benefits of any Participant hereunder, interfere in any way with the right of
the Company to terminate such Participant's employment at any time.

     Section 4.12. Governing Law. This Plan shall be governed in accordance with
the laws of the State of Texas (without giving effect to conflicts of laws
principles thereof) and applicable federal law.

     IN WITNESS WHEREOF, and as conclusive evidence of the adoption of this Plan
by the Holdings Board and the Chemicals Board, Holdings and Chemicals have each
caused this Plan to be duly executed in its name and behalf by its proper
officer thereunto duly authorized as of March 8, 2001.
