employment termination) shall terminate immediately on the date the Participant

exercisable only by him, or, if a Participant is mentally incapacitated, the
Award shall be exercisable by his guardian or legal representative. The
Committee may prescribe and include other restrictions on transfer in applicable
Award Agreements. Any attempted assignment or transfer in violation of this
Section shall be null and void. When the Participant dies, the Participant's

be prohibited except by will or the laws of descent and distribution, unless
transfers are made to the original Participant or a person to whom the original
Participant could have transferred as described above. No transfer shall be
effective unless and until the Committee is provided with written notice of the
transfer, in the form and manner the Committee prescribes . Following transfer,
any Awards shall continue to be subject to the same terms and conditions that
applied immediately before transfer, and, except as otherwise provided, the term
"Participant" shall be deemed to refer to the transferee. The consequences of
Employment termination shall continue to apply to the original Participant, and,
after Employment termination, the Awards shall be exercisable by the transferee
only to the extent and for the periods specified in this Plan and the Award
Agreement.

     10. Adjustments.

     (a) The existence of outstanding Awards shall not affect the Company's or
its Partners' right or power to make or authorize any or all adjustments,
recapitalization, reorganizations or other changes in the ownership of the
Company or its business or any Company merger or consolidation, or any issue of
bonds, debentures, preferred or prior preference stock (whether or not the issue
is prior to, on a parity with or junior to the Common Stock) or other
obligations, or the Company's dissolution or liquidation, or any sale or
transfer of all or any part of its assets or business, or any other Company act
or proceeding of any kind, whether or not similar to the acts or proceedings

     (b) If any Common Stock distribution, split, recapitalization,
extraordinary distribution, merger, consolidation, combination or exchange of
shares of Common Stock occurs or if the Company's ownership structure changes,
or a merger, consolidation or similar corporate transaction involving the
Company or an Affiliate occurs, or there is a sale of a substantial portion of
the Company's or an Affiliate's assets, or any other event occurs that the
Committee determines justifies an adjustment, the Committee may adjust
outstanding Awards as it deems necessary and appropriate in its sole discretion.
Adjustments include, but are not limited to, modifying Weighting Factors,
Proportional Fair Market Value and the formula to calculate Composite Fair
Market Value, issuing additional or substitute Awards, adjusting the Exercise
Price and/or number of Option Shares associated with Equistar Options,
accelerating exercisability of Equistar Options or the vesting of Restricted
Equistar Shares, immediately cashing out Equistar Options or Restricted Equistar
Shares or adjusting Performance Goals and targets associated with Performance
Shares and Cash Awards.

     11. Tax Withholding. The Company has the right to deduct applicable taxes
from any Award payment and, when cash is delivered under this Plan, to withhold
an appropriate amount of cash to pay taxes required by law or to take other
action necessary in the Company's opinion to satisfy all tax withholding
obligations.

     12. Amendment or Termination. The Committee may amend, alter or discontinue
this Plan, but no amendment or alteration that would impair any Participant's
right under any Award that he has been granted shall be made without his
consent. No Awards shall be granted more than ten years after the Effective
Date.

is satisfied based on the advice of its counsel that payment will comply with
applicable federal and state securities laws.

accounts may be established for Participants who are entitled to cash or rights
under this Plan, any account is used merely as a bookkeeping convenience. The
Company shall not be required to segregate any assets that may at any time be
represented by cash or rights, nor shall this Plan be construed to provide for
segregation, nor shall the Company, the Partnership Governance Committee or the
Committee be deemed to be a trustee of any cash or rights granted under this
Plan. Any Company liability or obligation to any Participant for a grant of cash
or rights under this Plan shall be based solely on any contractual obligations
created by this Plan and any Award Agreement, and no Company liability or
obligation shall be deemed to be secured by any pledge or other encumbrance on
any Company property. Neither the Company, the Partnership Governance Committee,
the Committee or any Affiliate is required to give any security or bond to
perform any obligation created by this Plan.

     15. Miscellaneous. Any Award granted under this Plan shall not impose any
obligation on the Company to maintain any Participant as an Employee and shall
not diminish the Company's or any Affiliate's power to discharge any Participant
at any time.

                                                                          Page 7
