2006 Fourth Quarter Financial Results
- -------------------------------------

For the three months ended December 31, 2006, Lilly ICOS reported net income of
$99.9 million, compared to $61.4 million for the three months ended December 31,
2005. Net income for the 2006 fourth quarter was consistent with the guidance
provided by ICOS Corporation in its press release on December 14, 2006. Reported
net income of $99.9 million, in the 2006 fourth quarter, includes the impact of
an increase in wholesaler inventories, an adjustment to royalty income for prior
periods and changes in currency exchange rates on non-U.S. revenues and
expenses, which collectively total approximately $3.8 million and were not
considered in the December 14, 2006 guidance.

Total Lilly ICOS revenue for the fourth quarter of 2006 was $226.7 million,
compared to $174.5 million for the fourth quarter of 2005. It is estimated that
there was a $2.1 million increase in U.S. wholesaler inventories at December 31,
2006, compared to September 30, 2006. Lilly ICOS revenue for the fourth quarter
of 2006 included $12.0 million in royalties on sales reported by Lilly, compared
to $9.0 million in royalty revenue for the fourth quarter of 2005. Royalty
revenue in the fourth quarter of 2006 includes $1.1 million related to
reconciliations of third party sales for prior periods.

In the U.S., market share of total prescriptions of Cialis was 27.1% for the
three months ended December 2006, an increase of 0.8 percentage points compared
to the three months ended September 2006. (3) Based on total prescriptions, the
U.S. ED market grew 4.1%, for the three months ended December 2006, compared to
the three months ended September 2006. Across Europe, Canada, and Mexico, Cialis
captured 35.6% of aggregate market share (tablets shipped from wholesalers to
pharmacies) for the three months ended November 2006, an increase of 0.2
percentage points compared to the three months ended August 2006. (4) Compared
to the 2006 third quarter, changes in currency exchange rates (primarily the
Euro and British Pound) added approximately $0.8 million to reported net income
in the 2006 fourth quarter.

Selling, general and administrative expenses increased $9.9 million from the
fourth quarter of 2005, to $94.4 million in the fourth quarter of 2006. The
increase was primarily due to increased U.S. consumer marketing expenses,
partially offset by the impact of refinements in the U.S. sales force
configuration.


2006 Full-Year Financial Results
- --------------------------------

For the year ended December 31, 2006, Lilly ICOS reported net income of $320.3
million, compared to $37.8 million for the year ended December 31, 2005,
primarily reflecting a $224.4 million increase in worldwide sales of Cialis and
a $96.8 million reduction in selling, general and administrative costs.

Total Lilly ICOS revenue for 2006 was $800.9 million, compared to $610.7 million
for 2005. Lilly ICOS revenue for 2006 includes $45.7 million in royalties on
sales reported by Lilly, compared to $34.0 million in royalty revenue for 2005.
Royalty revenue for 2006 includes $2.6 million related to reconciliations of
third party sales. The increase in total revenue reflects the impact of market
share gains, market growth and price increases.

Cost of sales totaled $59.7 million in 2006, including royalties payable by
Lilly ICOS equal to 5% of its net product sales. Cost of sales, as a percentage
of net product sales, was 7.9% in 2006, compared to 8.2% in 2005. The percentage
decrease was primarily the result of price increases in 2005 and 2006.

Selling, general and administrative expenses were $363.0 million for the year
ended December 31, 2006, compared to $459.8 million for the year ended December
31, 2005. The decrease was primarily due to refinements in the U.S. sales force
configuration and lower consumer marketing expenses.
