"Cialis delivered strong worldwide sales in the second quarter, due to both
gains in market share and growth of the ED market," said John Bamforth,
Director, International Marketing, for Lilly. "Cialis has continued to increase
market share across the Lilly ICOS territories every quarter since it was
launched, in 2003. We are especially pleased to note the resumption of
year-over-year growth in the U.S. ED market in the second quarter 2006."

In the U.S., market share of total prescriptions of Cialis reached 26.1% in June
2006, an increase of 2.8 percentage points from June 2005.(3) Across Europe,
Canada, and Mexico, Cialis captured 34.4% of aggregate market share in May 2006,
an increase of 3.5 percentage points from May 2005.(4) For the 2006 second
quarter, the U.S. ED market grew 3.3%, compared to the second quarter of
2005.(5)

Within the past three months, Lilly ICOS has submitted regulatory filings in
Europe and Canada, seeking approval for Cialis Once-A-Day to treat erectile
dysfunction. Lilly ICOS plans to file a supplemental new drug application, for
once-a-day dosing of Cialis, in the United States later this year.

"We are excited about the potential for Cialis as a once-a-day treatment for
ED," remarked Paul Clark, ICOS Chairman and CEO. "The ED medical experts that we
have consulted with are enthusiastic about the possibility that Cialis
Once-A-Day could provide a welcome alternative for the man with ED who takes a
PDE5 inhibitor more frequently than average. In market research, patients with
ED have expressed interest in the possibility of treating this chronic condition
with a once-daily tablet."

Lilly ICOS is continuing to evaluate tadalafil for potential benefits in
treating other medical indications. Later this year, Lilly ICOS is expected to
begin enrolling patients in a Phase 2b clinical study of tadalafil for the
treatment of benign prostatic hyperplasia (BPH). Results will be available from
the Phase 2 proof-of-concept study of tadalafil in hypertension this year. And,
patient enrollment is continuing in a Phase 3 clinical study of tadalafil for
the treatment of pulmonary arterial hypertension, a life threatening condition.


Financial Results
- -----------------

Lilly ICOS reported net income of $75.8 million for the three months ended June
30, 2006, compared to a net loss of $1.7 million for the three months ended June
30, 2005, reflecting a $42.3 million (22%) increase in worldwide sales of Cialis
and a $35.9 million (28%) reduction in selling, general and administrative
expenses.

Total Lilly ICOS revenue for the second quarter of 2006 was $194.3 million,
compared to $154.9 million for the second quarter of 2005, an increase of 25%.
The increase primarily reflects the impact of market share gains, market growth
and price increases. Royalty revenue in the second quarter of 2006 includes $1.5
million related to a reconciliation of third party sales.

Cost of sales was 7.9% of net product sales in the 2006 second quarter, compared
to 8.2% in the 2005 second quarter. The percentage decrease was primarily the
result of price increases in 2005 and 2006.

                                        2



The $35.9 million decrease in selling, general and administrative expenses, in
the second quarter of 2006, compared to the second quarter of 2005, was
primarily due to refinements in our U.S. sales force configuration and lower
consumer marketing expenditures in the second quarter of 2006.

Research and development expenses were $13.8 million in the second quarter of
2006, compared to $18.4 million in the second quarter of 2005. The decrease was
primarily the result of completing, in 2005, the BPH Phase 2 clinical study and
once-a-day dosing trials, as well as other regulatory studies, partially offset
by increased costs associated with the ongoing Phase 2 proof-of-concept study in
hypertension and Phase 3 clinical study in PAH.

For the six months ended June 30, 2006, Lilly ICOS reported net income of $140.7
million, compared to a net loss of $43.4 million for the six months ended June
30, 2005. The improvement was primarily due to the $115.0 million (34%) increase
in worldwide sales of Cialis and an $86.4 million (33%) reduction of selling,
general and administrative expenses.
