Mr. Eric D. Roiter
Senior Vice President and General Counsel
Fidelity Investments
82 Devonshire Street
Boston, MA 02109

Dear Mr. Roiter,

Lyondell Chemical Company is interested in and would like to address Fidelity's
concerns regarding the proposed Amended and Restated Lyondell Chemical Company
1999 Long-Term Incentive Plan (the "Plan"), as presented in Lyondell's Proxy
Statement dated April 4, 2002. We understand that Fidelity has two principal
areas of concern:

1.   The restriction period for restricted stock awards should normally be at
     lease three years. Restricted stock awards with a restriction period of
     less than three years (but at least one year) may be acceptable if the
     restricted stock award is performance based. Our practice has been to vest
     restricted stock in three equal annual installments, beginning one year
     after the date of grant. Management is willing to recommend to the
     Compensation Committee of Lyondell's Board of Directors that it adopt an
     amendment to the Plan to make its current practice explicit in the Plan.

2.   The Board or Compensation Committee should not be authorized to materially
     amend the Plan without shareholder approval. Management is willing to
     recommend to the Compensation Committee of Lyondell's Board of Directors
     that it adopt an amendment to the Plan to restate Section 14 in its
     entirety, as follows:

     Amendment or Termination. The Committee may amend, alter, or discontinue
     the Plan, but no amendment, alteration or discontinuation shall be made
     which would impair the rights of a Participant under any Award theretofore
     granted without the Participant's consent, except such an amendment made to
     cause the Plan to comply with applicable law, stock exchange rules or
     accounting rules. In addition, no such amendment shall be made without the
     approval of the Company's shareholders to the extent such approval is
     required by law or agreement or if such amendment would:

     (a)  expand the classes of persons to whom Awards may be made under Section
          3 of this Plan;

     (b)  increase the number of shares of Common Stock authorized for grant
          under Section 5 of this Plan;


     (c)  increase the number of shares which may be granted under Awards to any
          one Participant under Section 5 of this Plan;

     (d)  increase the number of shares available for Awards of Restricted
          Stock;

     (e)  permit unrestricted shares of Common Stock to be granted other than in
          lieu of cash payments under other incentive plans and programs of the
          Company and its Subsidiaries;

     (f)  allow the creation of additional types of Awards;

     (g)  permit shortening the restriction periods with respect to Restricted
          Stock Awards, the vesting periods with respect to Options or Phantom
          Stock or removing or waiving Performance Goals except to the extent
          permitted under Sections 9 and 11 of the Plan or as the Committee
          otherwise deems appropriate in the case of the death, disability or
          retirement of a Participant or with respect to a Change in Control of
          Lyondell; or

     (i)  change any of the provisions of this paragraph of Section 14.

          The Committee may amend the terms of any Option or other Award
     theretofore granted, prospectively or retroactively, but no such amendment
     (a) shall cause a Performance-Based Award to cease to qualify for the
     Section 162(m) exemption or (b) impair the rights of any Participant
     without the Participant's consent except such an amendment made to cause
     the Plan or Award to qualify for any exemption provided by Rule 16b-3.

          Subject to the above provisions, the Committee shall have authority to
     amend the Plan to take into account changes in law and tax and accounting
     rules as well as other developments, and to grant Awards which qualify for
     beneficial treatment under such rules without shareholder approval. No
     Awards shall be granted more than ten years after the Effective Date.

Please note that Section 6 of the Plan already prohibits a reduction in the
exercise price of outstanding Options. As a result, no amendment is necessary to
prohibit the repricing of Options.

We appreciate the opportunity to resolve your concerns regarding the Plan.

Sincerely yours,


KERRY A. GALVIN
