During the Co-Promotion Period, Altana shall not, and shall cause its Affiliates not to, directly or indirectly, (a) market, Promote, distribute, sell or accept orders for the sale of any Competing Product in the Territory, or (b) assist or cooperate in any way with any other Person in connection with the marketing, Promotion, distribution, selling or acceptance of orders for the sale of any Competing Product in the Territory.

(a) Altana shall indemnify, defend and hold harmless Salix and its officers, directors, partners, shareholders, employees and agents from and against any and all Damages arising out of or relating to (i) any breach of any covenant or undertaking of Altana, including, without limitation, any failure to obtain or maintain requisite approvals or licenses, and/or any failure to comply with Applicable Laws, including, without limitation, those prohibiting the “off-label” Promotion of the Product by Altana or its Representatives, (ii) the inaccuracy or breach of any representation or warranty made by Altana, (iii) the gross negligence or willful misconduct of Altana or its Representatives, or (iv) any claim or action of a third Party arising out of the performance of this Agreement by Altana or its Representatives.

(b) Salix shall indemnify, defend and hold harmless Altana and its Affiliates, officers, directors, partners, shareholders, employees and agents from and against any Damages arising out of or relating to (i) any breach of any covenant or undertaking of Salix, including, without limitation, any failure to obtain or maintain requisite approvals or licenses or any failure to comply with Applicable Laws, including, without limitation, those prohibiting the “off-label” Promotion of the Product by Salix or its Representatives, (ii) the inaccuracy or breach of any representation or warranty made by Salix, (iii) the gross negligence or willful misconduct of Salix or its Representatives, or (iv) any claim or action of a third Party arising out of the performance of this Agreement by Salix or its Representatives.

11.2. Notice and Control of Litigation. If any claim or liability is asserted in writing against a Party entitled to indemnification under Section 11.1 (the “Indemnified Party”) which would give rise to a claim under this Section 11, the Indemnified Party shall notify the person providing the indemnity (“Indemnifying Party”) in writing of the same within ten (10) days of receipt of such written assertion of a claim or liability. The Indemnifying Party shall have the right to defend the claim and control the defense, settlement and prosecution of any litigation,

provided that, unless the Indemnified Party otherwise agrees in writing, the Indemnifying Party may not settle the claim if such settlement does not include a complete and unconditional release of the Indemnified Party. The Indemnified Party shall have the right to participate, but not control, any such defense or settlement at its expense. If the Indemnifying Party, within fifteen (15) days after notice of such claim, fails to undertake to defend such claim, the Indemnified Party will (upon further notice to the Indemnifying Party) have the right to undertake the defense, compromise or settlement of such claim on behalf of and for the account and risk of the Indemnifying Party, subject to the right of the Indemnifying Party to assume the defense of such claim at any time prior to settlement, compromise or final determination thereof. All Parties agree to cooperate as reasonably necessary in the defense of such matters. Should the Indemnified Party fail to notify the Indemnifying Party in the time required above, the Indemnified Party shall not be entitled to indemnification for such claim to the extent that the Indemnified Party’s failure to notify in the time required above materially adversely affects the Indemnifying Party’s ability to defend such matter.

SALIX PHARMACEUTICALS ANNOUNCES XIFAXAN™ CO-PROMOTION

ALTANA Pharma US to Focus on Primary Care Physicians

RALEIGH, NC, February x, 2005 - Salix Pharmaceuticals, Ltd. (Nasdaq:SLXP) today announced that the Company has entered into a co-promotion agreement with ALTANA Pharma US, Inc. to promote XIFAXAN™ (rifaximin) tablets 200mg.

Under the terms of the agreement, ALTANA Pharma US will utilize one of its sales forces with approximately 250 representatives to promote XIFAXAN to the primary care physician market, which includes family practice, general practice and certain internal medicine physicians. This ALTANA sales force currently promotes Protonix® (pantoprazole) for the treatment of erosive gastroesophageal reflux disease (GERD) as part of a co-promotion agreement with Wyeth. Protonix is the most successful product of the ALTANA Pharma group with worldwide market sales of more than $3 billion in 2004. XIFAXAN is a nonsystemic, gastrointestinal-selective, oral antibiotic for the treatment of travelers’ diarrhea caused by noninvasive strains of E. coli in patients 12 years of age and older.

Commenting on the agreement, Xxxxxxx Xxxxx, President and Chief Executive Officer, Salix, stated, “We are very pleased with the opportunity this co-promotion provides for us to capture a greater share of the market for XIFAXAN. ALTANA Pharma is currently detailing one gastrointestinal product on the US market to primary care physicians, and XIFAXAN represents an excellent addition to their product offering to this target audience. This co-promotion will

allow Salix to continue to focus its sales efforts on its primary target audience – gastroenterologists – while at the same time allowing ALTANA Pharma the opportunity to expand the XIFAXAN market by generating exposure to its target audience - primary care physicians.”

Xxxx Xxxxxxxx, Vice President, Sales, ALTANA Pharma US, stated, “ALTANA Pharma is excited with the opportunity to co-promote XIFAXAN. We are focused on growing our business by means of diversifying our product portfolio in selected therapeutic areas. This agreement should serve as an excellent opportunity for our primary care sales force to expand our current gastroenterology business.”

Financial terms of the agreement were not disclosed.

Salix Pharmaceuticals, Ltd., headquartered in Raleigh, North Carolina, develops and markets prescription pharmaceutical products for the treatment of gastrointestinal diseases. Salix’s strategy is to in-license late-stage or marketed proprietary therapeutic drugs, complete any required development and regulatory submission of these products, and market them through the Company’s 100-member gastroenterology specialty sales and marketing team. XIFAXAN™ (rifaximin) tablets 200 mg are indicated for the treatment of patients (³12 years of age) with travelers’ diarrhea caused by noninvasive strains of Escherichia coli. XIFAXAN should not be used in patients with diarrhea complicated by fever or blood in the stool or diarrhea due to pathogens other than Escherichia coli. XIFAXAN should be discontinued if diarrhea symptoms get worse or persist more than 24-48 hours and alternative antibiotic therapy should be considered. In clinical trials, XIFAXAN was generally well tolerated. The most common side effects (vs. placebo) were flatulence 11.3% (vs. 19.7%), headache 9.7% (vs. 9.2%), abdominal pain 7.2% (vs. 10.1 %) and rectal tenesmus 7.2% (vs. 8.8%).
