Under the terms of the agreement, Almirall will provide Ironwood with
up to $55 million in near-term payments, including a $40 million upfront
licensing fee. Pre-commercial licensing fees and milestone payments total
$95 million. In addition, Ironwood will receive escalating royalties on
linaclotide sales. Almirall will be responsible for activities relating to
regulatory approval and commercialization, as well as expenses for the
European market. Ironwood continues to retain all rights to linaclotide
outside of North America and Europe.

"We are very pleased to be joining forces with Almirall to develop and
commercialize linaclotide for the millions of patients in Europe who suffer
from IBS-C and currently lack adequate therapies. Almirall presented us
with the best strategy to rapidly and effectively deliver linaclotide to
the market, and terms that, should linaclotide meet our expectations, allow
us to share approximately half of the long term value of the product," said
Peter Hecht, Ironwood's chief executive officer.

About Linaclotide

Linaclotide is a first-in-class compound in Phase 3 clinical
development for the treatment of IBS-C and chronic constipation (CC).
Linaclotide demonstrated proof of concept in a comprehensive Phase 2b
program, comprised of two clinical studies in over 700 patients with either
IBS-C or CC. In patients with IBS-C, linaclotide significantly reduced
abdominal pain and bloating and improved bowel function throughout the
12-week treatment period. In patients with CC, linaclotide reduced
constipation throughout the 4-week treatment period. In both studies the
most common adverse event was diarrhea. Linaclotide is a once daily, orally
delivered peptide that acts locally in the gut with no detectable systemic
exposure at therapeutic doses. Linaclotide is an agonist of guanylate
cyclase type-C, a receptor found on the lining of the intestine. Issued
composition of matter patents for linaclotide in the United States and
Europe provide protection beyond 2024. In September 2007, Ironwood and
Forest Laboratories, Inc. entered into a 50/50 collaboration to co-develop
and co-promote linaclotide in United States.

There are currently few available therapies to treat this disorder. In the
five major European markets alone, an estimated nine million patients
