In February 2006, Cialis had achieved market share leadership in eleven
countries, including France, Portugal, Saudi Arabia, South Africa and Venezuela.
In France, Cialis has been the market leader for 14 consecutive months and held
a 51% share for February 2006.(2)

"We are proud of the market share leadership Cialis has achieved," stated
Gaetano Crupi, Cialis Global Brand Development Leader for Lilly. "This time last
year, Cialis was the share leader in just five countries. As 2006 unfolds, we

expect Cialis to emerge as the category leader in additional markets as share
gains continue and overall sales continue to grow."

Lilly ICOS is evaluating the use of tadalafil, the active ingredient in Cialis,
for its potential use in a number of medical indications in addition to erectile
dysfunction.

Paul Clark, ICOS Chairman and CEO, added, "At this time, we are finalizing the
design of a Phase 2b clinical study to evaluate several doses of tadalafil for
symptoms of benign prostatic hyperplasia. Patient enrollment in a multi-national
Phase 3 study in pulmonary arterial hypertension continues. And, in the second
half of 2006, we expect to announce the results of the Phase 2 proof of concept
study in hypertension. We are excited that tadalafil might benefit patients in
additional indications."

2006 First Quarter Financial Results
- ------------------------------------

For the three months ended March 31, 2006, Lilly ICOS reported net income of
$65.0 million, compared to a net loss of $41.7 million for the three months
ended March 31, 2005, primarily due to the $72.6 million increase in worldwide
sales of Cialis and a $50.5 million reduction in selling, general and
administrative expenses.

Total Lilly ICOS revenue for the 2006 first quarter was $178.4 million, compared
to $119.0 million for the first quarter of 2005. Lilly ICOS revenue for the 2006
period included $11.1 million in royalties on sales reported by Lilly, compared
to $7.8 million in royalty revenue for the first quarter of 2005. The increase
in net sales of Cialis in the U.S. includes the impact of an estimated $27
million aggregate reduction in U.S. wholesaler inventories of Cialis in the 2005
first quarter.

Cost of sales, including royalties payable equal to 5% of net product sales, was
8.0% of net product sales in the 2006 first quarter, compared to 8.8% in the
2005 first quarter. The percentage decrease was primarily due to price increases
since the beginning of 2005.

The $50.5 million decrease in selling, general and administrative expenses, in
2006 compared to 2005, was primarily due to refinements to our U.S. sales force
configuration and lower direct to consumer marketing expenditures in the 2006
first quarter.
