Polymer and Petrochemical, Inc., a Delaware corporation ("Company"), and Wayne

as of January 1, 2004 (the "Effective Date"). The Company and the Executive are
sometimes referred to herein as the "Parties."

      This Agreement shall replace the employment agreement entered into between
Executive and Westlake Monomers Corporation (the "Prior Agreement"), which was
assigned to the Company as of January 1, 1996.

      1. Employment. The Company hereby employs the Executive and the Executive
hereby accepts continuing employment with the Company upon the terms and

Agreement, devote such of his entire time, attention, energies and business
efforts to his duties to the Company and its subsidiaries (the "Westlake Group")
as are reasonably necessary to carry out his duties specified in Paragraph 2.2
below. The Executive shall not, during the term of this Agreement, engage in any
other business activity (whether or not such business activity is pursued for
gain, profit or other pecuniary advantage) if such business activity would
impair the Executive's ability to carry out his duties hereunder. This Paragraph
2.1, however, shall not be construed to prevent the Executive from investing his
personal assets as a passive investor in such form or manner as will not
contravene the policies of the Westlake Group.
<PAGE>
      2.2. Position and Duties. The Executive shall serve as Vice President (or
in such other office of comparable or greater responsibility as the board of
directors of a Westlake Group company may determine) and shall perform,
faithfully and diligently, the services and functions relating to such office or
otherwise reasonably incident to such office as may be designated from time to
time by the board of directors of companies in the Westlake Group; provided that
all such services and functions shall be reasonable and within the Executive's
area of expertise; and provided further that the Executive shall be physically
capable of performing the same.

      3. Salary and Other Benefits. Subject to the terms and conditions of this
Agreement:

      3.1. Salary. As compensation for his services under and during the term of
his employment under this Agreement, the Executive shall be paid an annual base
salary ("Base Salary") of not less than $245,018.00, payable in accordance with
the Company's normal payroll practice. The Base Salary may be increased (but not
decreased) from time to time in the sole discretion of the Board of Directors.

      3.2. Other Benefits. As long as the Executive is employed hereunder, the
Executive shall be entitled to receive the following benefits in addition to his
Base Salary:

            (a) Executive shall be entitled to the benefits described in
      Paragraph 3.3 below.

            (b) The Executive shall have the right to participate in all group
      benefit plans offered by the Company (including without limitation,
      disability, accident, medical, vision, dental, life insurance,
      hospitalization, vacation, savings and pension), all
<PAGE>
      in accordance with the Company's regular policies with respect to its
      salaried employees. The Executive's service with BFG Intermediates Co.
      Inc. shall be considered for eligibility and vesting purposes on the same
      basis as other salaried employees hired by the Company from BFG
      Intermediates Co. Inc.

            (c) The Executive shall be entitled to reimbursement for reasonable
      out-of-pocket expenses incurred by him in the course of the performance of
      his duties hereunder in accordance with policies of the Company.

            (d) In order to promote the interests of the Westlake Group,

      benefits of the Company's relocation policy at any time during the term of
      this Agreement.

      3.3. Accrued Deferred Compensation. The Executive was awarded 600,000
"Units" in a deferred compensation "Plan" under the Prior Agreement. The Company
and Executive agree that the Plan, and in particular the formulas set forth
therein to derive the "Adjusted Value" of a Unit, has ceased to function as a
meaningful measure of the Executive's contributions to the success of the
Company. In lieu of Executive's rights under the Prior Agreement in the "Plan,"
the Company agrees to pay Executive, and Executive agrees to accept from the
Company, as deferred compensation to
<PAGE>
Executive, a lump-sum payment in the amount of $1,781,385.00 (the "Deferred
Payment"). The Deferred Payment shall be payable on the earlier of (1) the date
Executive retires or otherwise ceases to be an employee of the Company for any
reason, and (2) January 3, 2005.

      4. Term. The term of this Agreement shall be for an initial period of two
years commencing on the Effective Date and ending on December 31, 2005, and
shall thereafter automatically be extended on a year-to-year basis unless either
the Executive or the Company gives the other Party ninety (90) days written
notice prior to the date that the term of this Agreement would otherwise expire.

      5. Termination and Resignation. The Company shall have the right to
terminate the Executive's employment hereunder at any time and for any reason,
and upon any such termination the Executive shall be entitled to receive from
the Company prompt payment of the amount determined pursuant to the applicable
sub-paragraph of Paragraph 6 below. The Executive shall have the right to
terminate his employment hereunder at any time by retirement or resignation, and
he shall thereupon be entitled to receive from the Company prompt payment of the
amount determined pursuant to the applicable sub-paragraph of Paragraph 6 below.

      6. Payments Upon Termination and Resignation.

      6.1. Pro Rata Payment. If the Executive dies, becomes disabled (being the
inability of the Executive to perform his normal employment duties for the
remainder of the term of this Agreement because of either physical or mental
incapacity), is terminated for Cause or voluntarily resigns (as defined in
Paragraph 3), then in each case the Executive shall be entitled to receive (in
addition to the Deferred Payment under
<PAGE>
Paragraph 3.3) only his Base Salary on a pro rata basis to the date of death,
disability, termination for Cause or voluntary resignation.

      6.2. Base Salary Payment. If the Company terminates the Executive's
employment without Cause, then the Executive shall be entitled to receive (in
addition to the Deferred Payment under Paragraph 3.3) his Base Salary to the
date of termination and a lump sum payment equal to one year's Base Salary.

      7. Preservation of Business; Fiduciary Responsibility. The Executive shall
use his best efforts to preserve the business and organization of the Westlake
Group companies, to keep available the services of their present employees and
to preserve their business relations with their suppliers, distributors,
customers and others. The Executive shall not commit any act, or in any way
assist others to commit any act, which would injure the Westlake Group. So long
as the Executive is employed hereunder, the Executive shall observe and fulfill
proper standards of fiduciary responsibility attendant upon his service and
office and shall comply with the terms of the policy statements of all the
companies in the Westlake Group.

written, between the Parties with respect to the subject matter hereof, but this
Agreement shall not replace or supersede any current or future agreements or
understandings with other companies in the Westlake Group to the extent they

the original intent of this Agreement to the extent legally possible, but all
other provisions of this Agreement shall remain in full force and effect.

Company and the Company shall continue all its financial obligations contained
in this Agreement, including the Deferred Payment.

      In the event of an assignment of this Agreement, all covenants, conditions
and provisions hereunder shall inure to the benefit of and be enforceable

and the same instrument.

provision of the Agreement by the other Party shall not operate or be construed
as a waiver by such Party of any subsequent breach of such other Party.

under this Agreement all federal, state, city or other taxes as may be required
pursuant to any law or governmental regulation or ruling.
