                       ICOS Corporation Reports Net Income
        of $9.7 Million, Fifteen Cents Per Share, for 2006 Third Quarter



    BOTHELL, Wash.--(BUSINESS WIRE)--Nov. 2, 2006--ICOS Corporation
(Nasdaq:ICOS) today released its financial results for the three and
nine months ended September 30, 2006, and summarized recent events.

    For the three months ended September 30, 2006, ICOS reported net
income of $9.7 million ($0.15 per share), compared to a proforma net
loss of $19.3 million ($0.30 per share) for the three months ended
September 30, 2005.(1)

    Lilly ICOS'(2) 2006 third quarter net income grew to $79.6
million, compared to $19.8 million in the 2005 third quarter.
Worldwide sales of Cialis(3) in the third quarter of 2006 totaled
$245.6 million, an increase of 26% compared to $195.1 million in the
third quarter of 2005.

    During the third quarter of 2006, Lilly ICOS initiated a
double-blind, placebo-controlled Phase 2b clinical study to evaluate
tadalafil (the active ingredient in Cialis) as a potential treatment
for the symptoms of benign prostatic hyperplasia (BPH). Patients in
the study are to be administered one of four doses of tadalafil or
placebo, once-a-day for 12 weeks. The study is designed to enroll more
than 1,000 patients and may serve as a pivotal study to support
regulatory filings seeking approval of tadalafil for the treatment of
BPH.

    Patient enrollment is progressing on schedule in a 400 patient,
multi-national Phase 3 study evaluating the efficacy and safety of
tadalafil in treating patients with pulmonary arterial hypertension.

    Later this year, Lilly ICOS expects to file, with the FDA, for an
expanded indication for Cialis, as a once-a-day treatment for men with
erectile dysfunction. Regulatory filings for Cialis, as a once-a-day
treatment for erectile dysfunction, occurred in Europe and Canada in
mid-2006.

    A Lilly ICOS proof-of-concept Phase 2 study, in hypertension, was
recently completed, in which 180 patients were dosed once-a-day with 5
mg tadalafil, 20 mg tadalafil, or placebo, for eight weeks. The
results were consistent with results previously reported from clinical
pharmacology studies conducted for the ED indication. Patients in the
5 mg tadalafil group had a mean blood pressure decline of 5.5/7.5 mm
Hg. Patients in the 20 mg tadalafil group had a mean blood pressure
decline of 5.5/8.3 mm Hg. Results at both doses were statistically
significantly better than the mean 2.1/3.0 mm Hg decrease noted among
patients in the placebo group. Treatment was well tolerated by the men
and women in the study. Dyspepsia and headache were the most frequent
adverse events. The magnitude of reduction in blood pressure induced
by tadalafil in this clinical trial would likely be insufficient for
tadalafil to compete successfully in the broad hypertension
marketplace for first line therapy. Lilly ICOS is considering next
steps for this program.

    Our 50% share of Lilly ICOS earnings was $40.0 million in the
third quarter of 2006, compared to $10.0 million in the third quarter
of 2005. The $30.0 million improvement primarily reflects growth in
the sales of Cialis around the world and planned reductions in
marketing and selling expenses.

    ICOS Corporation's total revenue was $20.6 million in the third
quarter of 2006, compared to $20.8 million in the third quarter of
2005.

    Collaboration revenue from Lilly ICOS totaled $16.4 million in the
2006 third quarter, compared to $13.6 million in the third quarter of
2005. The increase primarily reflects reimbursable costs of 40
contract (non-employee) sales representatives retained to promote
Cialis in the U.S. beginning in January 2006.

    Co-promotion services revenue was $1.8 million in the 2005 third
quarter, representing fees earned under a co-promotion arrangement
which ended in December 2005.

    Total operating expenses were $51.3 million for the three months
ended September 30, 2006, compared to proforma $49.9 million for the
three months ended September 30, 2005. Operating expenses for the
three months ended September 30, 2006 include $5.4 million in stock
option expense, due to a change in accounting for employee stock
options effective January 1, 2006. On a proforma basis, operating
expenses for the three months ended September 30, 2005 include $7.9
million in stock option expense.

    For the nine months ended September 30, 2006, ICOS reported net
income of $15.1 million ($0.23 per share), compared to a proforma net
loss of $104.0 million ($1.63 per share) for the nine months ended
September 30, 2005.(4)

    At September 30, 2006, we had cash, cash equivalents, investment
securities and associated interest receivable of $187.8 million.

    On October 17, 2006, ICOS announced that it had entered into an
Agreement and Plan of Merger with Eli Lilly and Company, whereby Lilly
will acquire all of the outstanding stock of ICOS for a purchase price
of $32 per share in cash. Closing of the transaction is expected
around 2006 year-end, subject to approval by the shareholders of ICOS
and other customary closing conditions.

Bothell, Washington, is dedicated to bringing innovative therapeutics
to patients. Through Lilly ICOS LLC, ICOS is marketing its first
product, Cialis (tadalafil), for the treatment of erectile
dysfunction. ICOS is working to develop treatments for serious unmet
