            WellPoint Reports 2003 Second Quarter Earnings
                      of $1.49 Per Diluted Share


    THOUSAND OAKS, Calif.--(BUSINESS WIRE)--July 22, 2003--WellPoint
Health Networks Inc. (NYSE:WLP), the nation's second largest health
insurer, today announced that net income for the quarter ended June
30, 2003 was $224.5 million, or $1.49 per diluted share. Net income
for the second quarter of 2002 was $166.7 million, or $1.09 per
diluted share, before an extraordinary gain. Including the
extraordinary gain, which was discussed in the Company's second
quarter 2002 earnings press release, net income for the second quarter
of 2002 was $170.7 million, or $1.12 per diluted share.
    Medical membership was 13.4 million at June 30, 2003, compared
with 13.0 million at the end of the second quarter of 2002. The
year-over-year increase in membership resulted from strong sales in
WellPoint's key geographies, primarily California, Georgia and
Missouri. During the second quarter, the Company's medical membership
declined by 73,000 members, primarily because of membership reductions
in existing accounts related to the soft economy, higher lapse rates
in small and large group employer business in California due to price
increases, the withdrawal from the Medi-Cal program in Orange County,
California, and the attrition of two large non-risk accounts in the
Company's HealthLink business.
    Specialty membership was 49.4 million at June 30, 2003, compared
with 45.3 million at June 30, 2002. The increase in specialty
membership was due primarily to growth in the pharmacy benefit
management, behavioral health, dental and life insurance businesses.
    "Our ability to offer a broad array of innovative products that
are priced right is key to our outstanding performance," said Leonard
D. Schaeffer, WellPoint's chairman and chief executive officer. "We
also are effectively using technology to enhance customer service and
reduce administrative expenses."

    Highlights from the second quarter of 2003 include:

    --  Revenues exceeded $4.9 billion, up 15 percent from the second
        quarter of 2002

    --  The medical care ratio of 81.0 percent was lower than the
        first quarter of 2003 (81.7 percent) and the second quarter of
        2002 (81.5 percent)

    --  The selling, general and administrative expense ratio of 16.0
        percent was lower than the first quarter of 2003 (16.4
        percent) and the second quarter of 2002 (16.7 percent)

    --  WellPoint signed a definitive merger agreement on June 3, 2003
        with Cobalt Corporation, the publicly traded holding company
        of Blue Cross & Blue Shield United of Wisconsin

    --  WellPoint completed its acquisition of Golden West Dental &
        Vision, adding more than 275,000 dental and vision members, on
        June 30, 2003

    "WellPoint's continued focus on its business process resulted in
another strong quarter," said David C. Colby, WellPoint's chief
financial officer. "Our disciplined focus on pricing resulted in
strong revenue growth and higher operating margins. Due to this strong
performance, the Company's debt-to-total capitalization ratio was
reduced from 22.5 percent at March 31, 2003 to 20.9 percent at June
30, 2003."
    Operating cash flow for the second quarter of 2003 was $108
million. Operating cash flow for the quarter was affected by income
tax payments of $306 million resulting from increased taxable income
and the timing of quarterly estimated tax payments. In addition, cash
flow was affected by the delayed timing of payments from the Medi-Cal
program ($38 million) which were received in early July 2003.
    "This quarter we are providing more information for shareholders
to understand our estimate of medical claims payable," Colby
continued. "Days in medical claims payable increased by 0.1 days
during the second quarter. In addition, a six-month rollforward of
medical claims payable shows a consistent reserving methodology from
the prior year."
    "As a result of our second quarter performance, we are increasing
our earnings per diluted share guidance for 2003 to the $5.60 to $5.65
range from the previous guidance of $5.50," said Colby.

ended June 30, 2003 is scheduled to begin at approximately 11:00 a.m.

(A) Results of operations for the six months ended June 30, 2002
    included five months of RightCHOICE operating results.

(B) In April 2002, the FASB issued Statement of Financial Accounting
    Standards No. 145, "Rescission of FASB Statements No. 4, 44 and
    64, Amendment of FASB Statement No. 13, and Technical Corrections
    as of April 2002" ("SFAS No. 145"). With the rescission of FASB
    Statement No. 4, gains and losses from the extinguishment of debt
    should be classified as extraordinary items only if they meet the
    criteria in APB Opinion No. 30. In applying the provisions of APB
    Opinion No. 30, WellPoint had determined that the extinguishment
    of debt under its Zero Coupon Convertible Subordinated Debentures
    did not meet the requirements of unusual or infrequent and
    therefore would not be included as an extraordinary item with the
    rescission of FASB Statement No. 4. For the six months ended June
    30, 2002, WellPoint reclassified an extraordinary loss of $2.1
    million, which includes a tax benefit of $0.8 million, to interest
    expense.

The table above shows the components of changes in medical claims
payable for the periods indicated. Medical claims payable include
claims in process as well as provisions for the estimate of incurred
but not reported claims and provisions for disputed claims
obligations. Such estimates are developed using actuarial principles
and assumptions that consider, among other things, contractual
requirements, historical utilization trends and payment patterns,
benefits changes, medical inflation, product mix, seasonality,
membership and other relevant factors. In developing its best estimate
of medical claims payable, the Company consistently applies the
principles and assumptions listed above from year to year, while also
giving due consideration to the potential variability of these
factors. Because medical claims payable includes various actuarially
developed estimates, the Company's actual claims expense may be more
or less than the Company's previously developed estimates. As shown in
the table above, for each of the six months ended June 30, 2003, 2002
and 2001, the Company's actual health care claim expenses related to
prior years have been less than the estimates previously made by the
Company.
