Summary of Current CVX Terms

 

Three month process, which culminated in merger
agreement announcement on April 4, 2005

All known interested parties, including CNOOC, were
included

UCL provided equal information and access to all
interested parties

Board directed the process and was active in every step

CNOOC engaged in thorough due diligence but failed to
put in a bid

Original Chevron Merger Agreement

 

On June 22, 2005, CNOOC presented Unocal with an
unsolicited proposal

Proposed acquisition would be financed through approximately              
$16 billion of debt and $3 billion of available cash of UCL and CNOOC

CNOOC’s parent company (an entity wholly owned by the Chinese
government) agreed to finance up to $7 billion of the purchase price
through financing on terms that were favorable to CNOOC

UCL immediately sought and obtained a merger agreement
waiver from CVX to allow full and complete discussions and
negotiations with CNOOC to firm up the proposal

After obtaining the waiver, UCL provided CNOOC with
continued information and access

CNOOC $67/share Proposal

 

Board directed UCL’s management and advisors to address
major contractual risks with CNOOC before discussing the
price level of the bid

Enforceability

CNOOC has no U.S. assets

Judgments of U.S. courts are not recognized in China, where
CNOOC has the vast majority of its assets

U.S. approvals, particularly Exon-Florio

Transaction requires a recommendation from Committee on
Foreign Investments in the U.S. (“CFIUS”) and presidential
approval

90-day process (before giving effect to pending legislation)

Could preclude transaction closing

Certainty of consummation notwithstanding lengthy approval
process

CNOOC $67/share Proposal (cont’d.)

 

Board sought improved offers from both CNOOC and CVX

CNOOC acknowledged board authorization for $69 bid, but
declined to increase above $67

CNOOC discussed with UCL the possibility of (but did not
make) a highly conditional $69/share offer.  CNOOC’s
conditions:

Unocal (rather than CNOOC) to pay the CVX breakup fee
(despite prior CNOOC agreement to pay)

Unocal to support the bid in all forums (even though this would
result in breach of the CVX agreement)

Unocal Board to change its recommendation in favor of CNOOC

In response to negotiations by UCL, CVX raised to its
current offer

UCL Negotiations After Receiving
CNOOC $67/share Proposal

 

Risks of political process in Congress and CFIUS approval process

Delays due to Hong Kong Stock Exchange approval process

Lengthy pre-closing process enhances the risk of external events
resulting in material adverse change or otherwise preventing
completion

Limitations to recovery of damages against CNOOC

Damages recoverable only if CNOOC breaches the agreement

No damage recovery for failure to obtain U.S. and foreign regulatory
clearances, including CFIUS or failure to close due to material adverse
change

Potential recovery from proposed $2.5 billion escrow (< $6/share after tax)
could be far less than actual damages suffered and result in prolonged
litigation before any recovery is received

Difficulties in enforcing in foreign courts judgments obtained in the U.S.

Material Factors in Board’s Decision to
Recommend New CVX Transaction

 

State and local governmental issues relating to UCL
environmental liabilities and guarantees

Difficulties of retaining and motivating key employees in
the event of a new, prolonged pre-closing period

Cash vs. stock and cash

Long-term value of CVX and short-term negative effects
of the current situation on the current value of CVX stock

Material Factors in Board’s Decision to
Recommend New CVX Transaction
(cont’d.)

 

We recommend the CVX offer

Board is willing to accept the additional risks and
complexities of a CNOOC transaction if the price offered     
is sufficient to compensate UCL stockholders for the
additional risks

The CNOOC offer may not be available to UCL
stockholders in the future, including if UCL stockholders do
not approve the CVX agreement at the August 10 meeting

CNOOC is not bound by either the current offer or the
contractual protections negotiated by UCL in such event
