gastrointestinal diseases, to sell our products.

We currently market our products, and intend to market future products, if approved by the U.S.
Food and Drug Administration, or FDA, to U.S. gastroenterologists through our own direct sales force. We enter into distribution or licensing relationships outside the United States and in certain markets in the U.S. where a larger sales
organization is appropriate. Currently, our sales and marketing staff consists of approximately 150 people. We believe our sales force also should position us to sell additional products, if and when acquired and/or approved for U.S. marketing.

PRODUCTS

Xifaxan® (rifaximin) tablets

Xifaxan is
a gastrointestinal-specific oral antibiotic that the FDA approved in May 2004 for the treatment of patients 12 years of age and older with travelers diarrhea caused by noninvasive strains ofE coli. According to the Centers for Disease
Control, each year between 30% and 50% of international travelers, an estimated 20.0 million people, develop diarrhea, with approximately 80% of the cases caused by bacteria. Approximately 6.8 million people sought treatment in the United
States for infectious diarrhea in 2006 and approximately 4.1 million of those patients were prescribed a drug.

We believe the
advantages of Xifaxan to treat these infections are two-fold: (1) site-targeted antibiotic delivery; and (2) improved tolerability compared to other treatments. Less than 0.5% of the drug is absorbed into the bloodstream when it is taken
orally. In addition, the drug might also cause fewer side effects or discomforts such as nausea, headache or dizziness than observed with currently available, more highly-absorbed antibiotics. We believe Xifaxan is also less likely to cause harmful
interaction with other drugs a patient may be taking. Furthermore, we believe Xifaxan is unique because there is no other U.S.-approved oral antibiotic with its potential lack of systemic absorption and safety profile.

We launched Xifaxan in the United States in July 2004 using our own direct sales force. We had net product sales of $9.8 million, $30.1 million, $51.6
million and $64.3 million of Xifaxan in the United States in 2004, 2005, 2006 and 2007, respectively. We are exploring potential additional indications, formulations, clinical trials and co-promotion arrangements to capitalize on the potential for
Xifaxan, including our development programs in irritable bowel syndrome, hepatic encephalopathy, C. difficileassociated diarrhea, and prevention of travelers diarrhea. Based on these potential indications, we believe Xifaxan can
potentially compete in an annual U.S. market in excess of approximately $4 billion, comprised of over 12 million patient visits. While the potential market for Xifaxan is large, we expect to capture only a portion of each market due to
competition, market acceptance and/or other factors.

The patents for the rifaximin composition of matter (also covering a process of
making rifaximin and using rifaximin to treat gastrointestinal infectious diseases) expired in May 2001 in the United States and Canada. In May 2006, a U.S. patent (composition of matter and process patent that covers several physical states of
rifaximin) was

##### Table of Contents

issued that we believe extends the patent coverage of the current form of rifaximin until May 22, 2024. Alfa Wasserman S.p.a., the patent owner, has
licensed rights to rifaximin in the United States to Salix. In July 2006, Salix entered into an agreement with Cedars-Sinai Medical Center for the right to use its patent and patent application relating to methods of diagnosis and treating irritable
bowel syndrome and other disorders caused by small intestinal bacterial overgrowth.

Visicol® and OsmoPrep® (sodium phosphate monobasic monohydrate, USP, sodium phosphate dibasic anhydrous, USP) tablets

In September 2005, we acquired Visicol with the completion of the acquisition of InKine Pharmaceutical Company, Inc. Visicol tablets are indicated for
cleansing of the colon as a preparation for colonoscopy in adults 18 years of age or older. Visicol was the first, and it and OsmoPrep are the only, tablet bowel cleansing products approved by the FDA and marketed in the United States. OsmoPrep is a
patented, second-generation tablet bowel cleansing product approved by the FDA in March 2006. OsmoPrep tablets are indicated for cleansing of the colon as a preparation for colonoscopy in adults 18 years of age or older. OsmoPrep offers potential
benefits compared to Visicol such as its lack of microcrystalline cellulose, smaller tablet size and possible lower dose administration. The patent for the formulation and use of OsmoPrep expires in 2013. An additional U.S. patent application for
OsmoPrep is pending that, if issued, could provide patent protection through 2024.

Approximately 5.2 million prescriptions for bowel
cleansing products were written in 2007, representing a market value of $191 million. In terms of prescription dollar sales, the market for bowel cleansing products has been growing at a 28% annual compound rate for the last 5 years. Visicol and
OsmoPrep compete with a number of liquid polyethylene glycol-salt (PEG-salt solution) bowel cleansing products and an over-the-counter oral sodium phosphate solution bowel cleansing product. Net product sales for Visicol were $14.4 million, $20.7
million, $19.9 million, $18.0 million and $2.2 million in 2003, 2004, 2005, 2006 and 2007, respectively. Net product sales for OsmoPrep were $22.5 million in 2006 and $25.4 million in 2007.

MoviPrep® (PEG 3350, sodium sulfate, sodium
chloride, potassium chloride, sodium ascorbate and ascorbic acid) oral solution

In December 2005, we acquired exclusive rights to sell
MoviPrep in the United States from Norgine B.V. MoviPrep is a patent-protected, liquid PEG bowel cleansing product that was approved by the FDA in August 2006. MoviPrep is differentiated from other currently marketed, liquid PEG bowel cleansing
products by the inclusion of ascorbic acid in its formulation. MoviPrep is indicated for bowel cleansing prior to colonoscopy, intestinal surgery and barium enema X-ray examinations. In January 2007 the United States Patent Office issued a patent
providing coverage to September 1, 2024. Net product sales for MoviPrep were $5.0 million in 2006 and $20.1 million in 2007.

Colazal® (balsalazide disodium) capsules

The FDA approved Colazal in 2000 for the treatment of mildly to moderately active uncreative colitis. We launched Colazal to physicians in the United States in January 2001 using our own sales force. In December 2006, the FDA approved
Colazal for use in pediatric patients between 5 to 17 years of age with ulcerative colitis. The pediatric use of Colazal has been granted orphan drug designation. On December 28, 2007, the Office of Generic Drugs, or OGD, approved three generic
balsalazide capsule products. On December 28, 2007, we announced that we had entered into an agreement with Watson Pharma, Inc. to market and sell an authorized generic of Colazal.

Ulcerative colitis is a chronic form of inflammatory bowel disease characterized by inflammation of the lining of the colon. Symptoms of active
ulcerative colitis include rectal bleeding, abdominal pain, increased stool frequency, loss of appetite, fever and weight loss. The cause of ulcerative colitis is unknown and no known cure exists except for the removal of the colon. It is estimated
that as many as 500,000 people in the United States have ulcerative colitis. People are most often diagnosed with the disease in their mid-30s, although the disease can occur at any age.

In clinical trials, Colazal demonstrated at least comparable efficacy and had an improved safety profile as compared to some other oral 5-ASA products.
Other 5-ASA products often do not deliver optimal doses of the active

##### Table of Contents

therapeutic agent to the colon. However, because Colazals proprietary formulation allows approximately 99% of the drug to reach the colon, it can work
more quickly and effectively than comparable doses of other 5-ASA products that deliver less drug to the diseased area.

We had net product
sales of $55.8 million, $85.4 million, $110.3 million, $103.5 million and $92.4 million of Colazal in the United States in, 2003, 2004, 2005, 2006 and 2007 respectively. Colazal net product revenues for 2007 include a $34.6 million reduction
representing our estimate of Colazal previously sold to wholesalers that may be returned to us under our return policy as a result of the generic approvals discussed above.

Azasan® (azathioprine) tablets

In November 2003, we acquired from aaiPharma LLC the exclusive right to sell 25, 75 and 100 milligram dosage strengths of azathioprine tablets in North
America under the brand name Azasan. Azasan is an FDA-approved drug that suppresses immune system responses and is indicated for preventing rejection of kidney transplants and treatment of severe arthritis. In February 2004, we launched the 75 and
100 milligram dosage strengths of Azasan in the United States. Net product sales for Azasan were $2.3 million, $4.4 million, $4.8 million and $3.4 million in 2004, 2005, 2006 and 2007, respectively. The patents and data exclusivity for Azasan have
expired.

Anusol-HC® and
Proctocort® (hydrocortisone) creams and suppositories

In June 2004, we
acquired the exclusive right to sell Anusol-HC 2.5% (hydrocortisone USP) cream, Anusol-HC 25 mg (hydrocortisone acetate) rectal suppositories, Proctocort 1% (hydrocortisone USP) cream and Proctocort 30 mg (hydrocortisone acetate) rectal
suppositories from King Pharmaceuticals, Inc. The two cream products are topical corticosteroids indicated for relief of the inflammatory and pruritic, or itching, manifestations of corticosteroid-responsive dermatoses. The two suppository products
are indicated for use in inflamed hemorrhoids and postirradiation proctitis, as well as an adjunct in the treatment of chronic ulcerative colitis and other inflammatory conditions. Combined net product sales for the Anusol-HC and Proctocort product
lines were $4.1 million, $4.8 million, $3.0 million and $2.9 million in 2004, 2005, 2006 and 2007, respectively. The patents and data exclusivity for Anusol-HC and Proctocort have expired.

Pepcid® (famotidine) for Oral Suspension and Oral
Suspension Diuril® (Chlorothiazide)

In February 2007, we purchased the U.S.
prescription pharmaceutical product rights to Pepcid Oral Suspension and Diuril Oral Suspension from Merck & Co., Inc. Pepcid Oral Suspension is a widely known prescription pharmaceutical product indicated for several gastrointestinal
indications, including the treatment of duodenal ulcer, benign gastric ulcer and gastro-esophageal reflux disease. The acquisition reflects the ongoing execution of our strategy to expand and diversify revenue. Pepcid Oral Suspension and Diuril Oral
Suspension, both liquid formulations of their solid dosage form counterparts, compete in a combined market of approximately $150 million that is concentrated in pediatric and hospitalized patient populations. Net product sales for Pepcid were $22.2
million in 2007. Net product sales for Diuril for 2007 were $0.2 million. The patents and data exclusivity for Pepcid Oral Suspension and Diuril Oral Suspension have expired.

DEVELOPMENT PROGRAMS

Balsalazide Disodium tablets

We have developed an 1100 mg tablet formulation of balsalazide disodium. We believe the convenience the balsalazide tablet formulation is designed to
provide, by means of twice-a-day dosing and a reduced number of pills, demonstrates our ongoing commitment to bring products to market that better serve the needs of gastroenterologists and their patients. On July 17, 2007 we submitted an NDA
to the FDA seeking approval to market an 1100 mg tablet formulation of balsalazide disodium. The application was accepted for filing and is currently under review. We anticipate receiving a response from the FDA by May 16, 2008. The patent for
balsalazide disodium tablets will expire in 2018.

Granulated Mesalamine

In July 2002 we acquired the exclusive development rights in the United States to a granulated mesalamine product from Dr. Falk Pharma GmbH, one of
the most recognized gastroenterology companies worldwide. As part of



4

##### Table of Contents

that transaction, we also received a right of first negotiation with respect to additional Falk products in the United States. The Falk granulated mesalamine
product has already been approved in most of the principal markets of Europe. The Falk granulated mesalamine formulation combines an enteric pH-dependent coating, which provides for delayed release, and a polymer matrix core, which provides for
extended release. This formulation is designed to provide for the distribution of the active ingredient beginning in the small bowel and continuing throughout the colon. If approved in the United States, the products unique prolonged release
mechanism might allow us to expand the range of treatment options for ulcerative colitis. On December 31, 2007 the Company submitted an NDA to the FDA seeking approval to market granulated mesalamine, dosed once-a-day, for the maintenance of
remission in patients with ulcerative colitis. We anticipate receiving a response from the FDA on our NDA for granulated mesalamine during the fourth quarter of 2008. The patent for the treatment of the intestinal tract with the granulated
mesalamine product will expire in 2018.

Xifaxan® (rifaximin) tablets

We are committed to maximizing the commercial potential of our GI-targeted
antibiotic, Xifaxan. We have prioritized our development efforts and have budgeted resources to expedite our late-stage trials in irritable bowel syndrome and hepatic encephalopathy. These studies are generating data that should provide the basis
for forthcoming New Drug Applications.

In September 2007 we announced the successful completion and outcome of our Phase IIb trial to
assess the efficacy and safety of rifaximin in the treatment of patients with diarrhea-associated irritable bowel syndrome (dIBS). Top-line results of this study demonstrate that the protocol-specified, intent-to-treat, co-primary endpoint
comparison of a 14-day course of rifaximin at 550 mg twice-a-day, provides a statistically significant improvement in both adequate relief of dIBS symptoms and adequate relief of bloating, compared to placebo. In December 2007 we met with the FDA to
discuss next steps in the development program. We anticipate initiating two Phase III trials in mid-2008.

The Phase III trial of rifaximin
in the treatment of patients with hepatic encephalopathy continued during 2007. We currently expect to complete patient enrollment in this study during the first quarter of 2008.

In January 2006 we announced the completion of our first of two Phase III trials to evaluate Xifaxan in the prevention of travelers diarrhea. In
this study 210 U.S. students in Mexico received either 600 mg of Xifaxan or a placebo daily for 14 days. The results of the study were highly statistically significant (p<0.0001) with 84 percent of Xifaxan-treated travelers remaining free from TD
versus 50 percent of placebo-treated travelers. In our second Phase III trial to evaluate rifaximin in the prevention of TD in travelers to Thailand, the incidence rate at which international travelers to southern Thailand acquired bacterial
diarrhea was lower than the historical incidence rate. Consequently, due to the low incidence of travelers diarrhea, the study was unable to determine the utility of rifaximin in this particular study population. We have a strong database of
information from other travelers diarrhea prophylaxis trials, and we intend to meet with the FDA to discuss these data and potential next steps. We are assessing the current status of enrollment in our C. difficile-associated diarrhea,
or CDAD, trial. At this time, the study remains open and patient enrollment continues. However, during 2008, we will continue to redirect funds previously allocated to patient recruitment in the CDAD trial to fund other initiatives.

Vapreotide acetate

In September 2006 we acquired
exclusive marketing rights for vapreotide acetate in the United States from the Debiopharm Group. The product is currently undergoing a confirmatory Phase III trial in the United States as a treatment of acute esophageal variceal bleeding. If
approved by the FDA, vapreotide acetate will be the only approved treatment for esophageal variceal bleeding in the United States. Vapreotide acetate has been granted orphan drug designation in the United States, and as a result, if approved, will
have seven years of exclusivity from the approval date.

Metoclopramide-Zydis®

In September 2007 we
acquired exclusive, worldwide rights to metoclopramide-Zydis® from Wilmington Pharmaceuticals. Metoclopramide is indicated for shortterm (412 weeks) therapy for adults with
symptomatic

documented gastroesphageal reflux who fail to respond to conventional therapy and for the relief of symptoms associated with acute and recurrent diabetic
gastric stasis. The licensed compound is a fast-dissolve formulation that has patent protection until 2022, and additional patent protection pending that, if issued, will provide patent protection until 2025. Wilmington has submitted an NDA seeking
approval to market metoclopramide-Zydis to the FDA. Wilmington anticipates receiving a response from the FDA during the fourth quarter of 2008.

COLLABORATIVE AND PRODUCT ACQUISITION AGREEMENTS

We have and will continue to enter into various collaborations and product
acquisition agreements with licensors, licensees and others. To date, we have entered into the following agreements:

Product Acquisitions and
In-License Agreements

aaiPharma LLC

In November 2003, we acquired from aaiPharma LLC for $2.0 million the exclusive right to sell 25, 75 and 100 milligram dosage strengths of azathioprine tablets in North America under the name Azasan. In addition, the agreement provides that
Salix is to pay aaiPharma, on a quarterly basis, a percentage royalty payment based on Salixs net sales of Azasan in exchange for aaiPharma supplying us with drug product. Because the amount of the royalty payment is based on net sales during
a quarter, with no minimum royalty amount, Salix is unable to prospectively disclose the absolute amount of such royalty payments. Royalties are only incurred if there is associated revenue, and then are included in Cost of products sold
in the Statements of Operations.

Alfa Wassermann S.P.A.

In June 1996, Salix entered into a license agreement with Alfa Wassermann S.p.A, a privately held pharmaceutical company headquartered in Italy, pursuant to which Alfa Wassermann licensed to Salix the exclusive rights
to make, use and sell rifaximin (Xifaxan) in the United States and Canada for the treatment of gastrointestinal and respiratory tract diseases. Pursuant to the license agreement, we agreed to pay Alfa Wassermann a net sales-based royalty, as well as
milestone payments. Salix made annual milestone payments in varying amounts to Alfa Wassermann until the commercial launch of Xifaxan in July 2004. No more milestone payments remain under this agreement. Our obligation to pay royalties commenced
upon the commercial launch of the product and continues until the later of (1) the expiration of the period in which the manufacture, use or sale of the products by an unlicensed third party would constitute an infringement on the patent
covering the product or (2) 10 years from commercial launch. Thereafter, the licenses granted to us shall continue as irrevocable royalty-free paid-up licenses. However, we would remain obligated to pay a net sales based royalty for use of the
product trademark if we choose to continue using it after the other licenses expired. Because the amount of the royalty payment is based on net sales during a quarter, with no minimum royalty amount, Salix is unable to prospectively disclose the
absolute amount of such royalty payments. Royalties are only incurred if there is associated revenue, and then are included in Cost of products sold in the Statements of Operations.

Alfa Wassermann has agreed separately to supply us with bulk active ingredient rifaximin at a fixed price. Salix is committed to purchase a percentage of
its rolling 12-month forecast that is updated monthly, and these amounts are included in the Purchase Commitments line of its contractual commitments table in its Managements Discussion and Analysis of Financial Condition and
Results of Operations.

The license agreement does not have a set term and continues until terminated in accordance with its terms. Either
party to the agreement may terminate it following a material breach by the other party and the failure of the breaching party to remedy the breach within 60 days. In addition, Alfa Wassermann has the right to terminate the agreement on three
months written notice in the event that we fail to sell the product for a period of six consecutive months after commercial launch. In addition, Alfa Wassermann may terminate the agreement if we become involved in bankruptcy, liquidation or
similar proceedings. We may terminate the agreement in respect of any indication or any part of the territory covered on 90 days notice, at which point our rights with respect to that indication or territory shall cease.

ALW Partnership

In connection with Salixs acquisition of InKine Pharmaceutical Company, Inc. in September 2005, Salix assumed a license agreement with ALW Partnership for the worldwide rights, in perpetuity, to develop, use,
market, sell, manufacture, have manufactured and sub-license Visicol and improvements, including OsmoPrep, in the field of colonic purgatives, along with ALW Partnerships body of proprietary technical information, trade secrets and related
know-how. Pursuant to this license agreement, Salix pays to Clinical Development Capital, ALWs successor, on a quarterly basis, a percentage royalty payment based on Salixs net sales of these products. Because the amounts of the royalty
payments are based on net sales during a quarter Salix is unable to prospectively disclose the amount of such royalty payments. The agreement requires a minimum annual royalty payment of $0.1 million.

Biorex Laboratories Limited

Pursuant to an agreement
entered into between us and Biorex in 1992, Biorex granted us the exclusive worldwide right (other than Japan, Taiwan, Korea and the United States) to develop, manufacture and sell balsalazide for all disease indications for a period of 15 years
from the date of commercial launch, subject to early termination in certain circumstances, including upon the material breach by either party and, in the case of Biorex, in the event of our bankruptcy or if a sub-licensee of ours terminates or
becomes entitled to terminate its sublicense as a result of actions by us. Pursuant to this agreement, Salix must pay to Biorex a percentage of any gross profits realized by Salix, plus a percentage of fees payable to Salix in connection with any
sublicense by Salix of the rights under the agreement. Under a separate agreement, Biorex granted us the exclusive right to develop, manufacture and sell balsalazide for all disease indications in the United States for a period of nine years from
the date of commercial launch or the term of the applicable patent, whichever is longer. Under these agreements, we paid Biorex fees upon entering into the agreements and are obligated to make additional milestone and royalty payments for the drug.
The royalty payments to be made by us pursuant to the agreement governing the United States are based on net sales, subject to minimum royalty payments for the first five years following commercial launch. Under the agreement governing territories
other than the United States, we are obligated to pay to Biorex a portion of any gross profit on sales of balsalazide outside the United States. Under these agreements, we undertook to complete preclinical testing, perform clinical trials and obtain
regulatory approvals for balsalazide. During 2001, we acquired from Biorex the exclusive right and license to develop, manufacture and sell balsalazide in Japan, Korea and Taiwan. There were no fees paid to Biorex upon entering into this agreement,
but we are obligated to pay Biorex a portion of any upfront payments, milestone payments and gross profit on sales of balsalazide in Japan, Korea and Taiwan as well. Because the amount of the royalty payment is based on net sales during a quarter,
with no minimum royalty amount, Salix is unable to prospectively disclose the absolute amount of such royalty payments. Royalties are only incurred if there is associated revenue, and then are included in Cost of products sold in the
Statements of Operations.

Cedars  Sinai Medical Center

On June 28, 2006, Salix entered into a license agreement with Cedars-Sinai Medical Center, or CSMC, for the right to use a patent and a patent application relating to methods of diagnosing and treating irritable
bowel syndrome and other disorders caused by small intestinal bacterial overgrowth. Under the agreement, CSMC grants Salix the right to use its patent and patent application relating to methods of diagnosis and treating irritable bowel syndrome and
other disorders caused by small intestinal bacterial overgrowth. CSMC also grants Salix a nonexclusive license to use any unpublished research and development information, know-how and technical data of CSMC as necessary to exploit all rights
granted to Salix with respect to rifaximin, with a right to sublicense. As of December 31, 2007, all of the aggregate $1.2 million license fee had been paid. A portion of the $1.2 million was considered an up-front, non-refundable and
irrevocable licensing fee. The balance was considered a prepaid, non-refundable and irrevocable royalty applicable as credit towards royalty amounts due and payable to CSMC, if any, under the agreement. At such time as the use of rifaximin is
approved by the FDA as a treatment for irritable bowel syndrome, Salix will be required to pay CSMC low single digit percentage royalties on net sales of licensed products. An additional term of the license agreement with CSMC provides that Salix
will expend a minimum amount per calendar year to seek and obtain regulatory approval and develop and commercialize licensed products. Because the license agreement provides the ability for Salix to terminate the agreement upon giving written notice
of not less than 90 days, Salix does not include amounts payable under the license agreement as a purchase obligation in its contractual commitments table in Managements Discussion and Analysis of Financial Condition and Results of Operations.

Debiopharm Group

The Debiopharm Group is a global biopharmaceutical development company headquartered in Lausanne, Switzerland. Debiopharm developed vapreotide acetate for the treatment of acute esophageal variceal bleeding. In
September 2006 we acquired the exclusive right to sell, market and distribute vapreotide acetate in the United States. The agreement provides that Salix make milestone payments in an aggregate amount of up to $7.5 million to Debiopharm upon certain
events prior to the commercial launch of the product, and quarterly royalty payments thereafter. As of December 31, 2007, $0.5 million of milestone payments had been made. The remaining milestone payment is contingent upon achievement of
regulatory approval. Because the milestone payment is conditioned upon events that might never occur, we do not consider the potential milestone payment as a purchase obligation nor a commitment to be reported in our contractual commitments table in
Managements Discussion and Analysis of Financial Condition and Results of Operations.

Dr. Falk Pharma GmbH

Pursuant to Salixs license agreement, as amended, with Dr. Falk Pharma GmbH, Salix acquired the rights to develop and market a granulated
formulation of mesalamine. The agreement provides that Salix make milestone payments in an aggregate amount of up to $11.0 million to Dr. Falk upon certain events prior to the commercial launch of the product, and quarterly royalty payments
thereafter. As of December 31, 2007, $3.0 million of milestone payments had been made. The majority of the remaining milestone payments are contingent upon filing a new drug application and achievement of regulatory approval. Because these
milestone payments are conditioned upon events that might never occur, we do not consider the potential milestone payments as purchase obligations nor a commitment to be reported in our contractual commitments table in Managements Discussion
and Analysis of Financial Condition and Results of Operations.

King Pharmaceuticals, Inc.

In June 2004, we acquired the exclusive right to sell Anusol-HC® 2.5% (hydrocortisone USP) cream, Anusol-HC® 25 mg (hydrocortisone acetate) rectal suppositories, Proctocort® 1% (hydrocortisone USP) cream and Proctocort® 30 mg (hydrocortisone acetate) rectal suppositories from King Pharmaceuticals, Inc. We paid $13.0 million cash
for the four products, and entered into a supply agreement for the suppository products and the Anusol-HC cream product with King Pharmaceuticals; an alternate supply arrangement with a contract manufacturer was put in place for the Proctocort cream
product. Once payment amounts under this and other supply agreements are known and are non-cancelable, Salix includes them in its contractual commitments table in Managements Discussion and Analysis of Financial Condition and Results of
Operations.

Merck & Co., Inc.

In February 2007, we entered into a Master Purchase and Sale and License Agreement with Merck & Co., Inc., to purchase the U.S. prescription pharmaceutical product rights to Pepcid Oral Suspension and Diuril Oral Suspension.
Pursuant to the Master Purchase and Sale and License Agreement, Salix paid Merck $55.0 million at the closing of the transaction. In addition, Salix will make additional payments to Merck up to an aggregate of $6.0 million upon the achievement of
certain annual gross sales targets for the acquired Pepcid Oral Suspension and Diuril Oral Suspension products during any of the five calendar years beginning in 2007 and ending in 2011. Because these payments are conditioned upon events that might
never occur, we do not consider these payments as purchase obligations nor a commitment to be reported in our contractual commitments table in Managements Discussion and Analysis of Financial Condition and Results of Operations.

In return for these payments, Salix obtained (1) all rights to the United States regulatory approvals and related data, open purchase orders,
inventory and customer lists related to the acquired oral suspension products, (2) an exclusive license to the Pepcid Oral Suspension and Diuril Oral Suspension trademarks for the use of prescription sale of the acquired oral suspension
products in the U.S., and (3) an exclusive license to certain know-how related to the manufacture of the acquired oral suspension products in the U.S. Merck also agreed to manufacture and supply the acquired oral suspension products to Salix
through December 31, 2008. In the event that Salix is acquired by another

##### Table of Contents

party or if Salix sells all or substantially all of the rights to the acquired oral suspension products, and Merck determines in its reasonable judgment that
such transaction will result in material harm to the Pepcid Oral Suspension name or the licensed trademark, Merck has the right to terminate one or more of the above licenses and the supply obligation.

In the event that a prescription or over-the-counter product with the same active ingredient and strength as Pepcid Oral Suspension is first sold by any
party other than Salix prior to December 2008, Merck shall pay Salix up to $15.0 million depending on the date of such first sale.

Norgine B.V.

In December 2005, we acquired from Norgine B.V. the exclusive rights to sell NRL944 (now marketed by us under the trade name MoviPrep),
a proprietary, liquid PEG bowel cleansing product in the United States. In return we will make upfront and milestone payments to Norgine that could total up to $37.0 million over the term of the agreement. As of December 31, 2007, $17.0 million
of milestone payments had been made. The remaining milestone payments are contingent upon reaching sales thresholds. Because these milestone payments are conditioned upon events that might never occur, we do not consider the potential milestone
payments as purchase obligations nor a commitment to be reported in our contractual commitments table in Managements Discussion and Analysis of Financial Condition and Results of Operations.

Wilmington Pharmaceuticals, LLC

In September 2007, we acquired the exclusive, worldwide right to sell
metoclopramideZydis® from Wilmington Pharmaceuticals, LLC. Under the agreement, we are obligated to make upfront and milestone payments that could total up to $8.0 million over the
term of the agreement. As of December 31, 2007, we had paid $500,000 of these milestone payments. The remaining milestone payments are contingent upon filing a new drug application and regulatory approval. Because these milestone payments are
conditioned upon events that might never occur, we do not consider the potential milestone payments as purchase obligations nor a commitment to be reported in our contractual commitments table in Managements Discussion and Analysis of
Financial Condition and Results of Operations.

Product Out-License Collaborations

Dr. Falk Pharma GmbH

In April 2007, we licensed to Dr. Falk exclusive rights to market
DIACOL 1500 mg Tablets in 28 territories in Europe. We sell DIACOL, or, sodium phosphate monobasic monohydrate, USP, and sodium phosphate dibasic anhydrous, tablets, USP, in the United States under the trade name OSMOPREP Tablets. As
part of the agreement, Dr. Falk also has a nonexclusive option to market DIACOL in Italy and France. Under the terms of the agreement, we may receive up to $4 million in milestone payments, as well as royalty payments based on product
sales. Dr. Falk made the first milestone payment of $1.5 million upon execution of the agreement. Dr. Falk is obligated to use all reasonable efforts to obtain Marketing Authorization by means of the Mutual Recognition Procedure in the
territories and option countries.

This agreement remains in effect until the later of the expiration of the underlying patent and April
2024, unless earlier terminated pursuant to its terms. Falk may terminate at any time with 24 months written notice if it reasonably considers that the continued exploitation of the products in the territory by it is no longer in its commercial
interests, provided that Falk shall have discussed such circumstance and consulted fully with Salix and the parties shall have discussed and if appropriate amended the minimum royalty payments. In the event there shall have occurred a material
adverse breach of the agreement by a party uncured for up to 120 days, the other party may terminate. In addition, Salix may terminate on four months notice upon a Falk change of control unless Falk makes a non-termination payment to Salix.

Menarini Pharmaceutical Industries S.R.L.

Menarini, headquartered in Italy, is the largest manufacturer and distributor of pharmaceuticals in Southern Europe. Menarini also has extensive experience developing and marketing therapies for gastrointestinal disease in its

##### Table of Contents

markets. Under our agreements with Menarini, we granted Menarini certain manufacturing rights and exclusive distribution rights with respect to balsalazide
in Italy, Spain, Portugal and Greece. The agreement calls for additional milestone revenues to be paid to us relating to additional European marketing approvals, if any, in the Menarini territories. Under the terms of the agreements, we will sell
the bulk active ingredient balsalazide to Menarini for marketing and distribution in its territories at cost plus a sales-based royalty. Menarini did not purchase any bulk active ingredient balsalazide from us during 2003, 2005, 2006, or 2007.
During 2004, Menarini paid us approximately $0.1 million related to balsalazide purchases.

Unless terminated sooner in accordance with its
terms, the agreement with Menarini continues until the earlier of the expiration of (1) the patents relating to the product or (2) 15 years from the date of the agreement, provided however that in any case the agreement shall continue for
a period of 10 years from the date of first launch. Either party may terminate the agreement upon a material breach by the other party and the failure to remedy such breach within 30 days in the case of a payment breach or 90 days in the case of any
other material breach or if a party enters liquidation, bankruptcy or similar proceedings.

Mayoly-Spindler S.A.S.

In October 2007, we licensed exclusive rights to market OSMOPREP (sodium phosphate monobasic monohydrate, USP and sodium phosphate dibasic
anhydrous, USP) Tablets in France to MayolySpindler S.A.S of Chatou, France. Under the terms of the agreement, we may receive up to $1 million in milestone payments, as well as royalty payments based on product sales. MayolySpindler will
join the current mutual recognition process being conducted by Dr. Falk Pharma to obtain Marketing Authorization in Europe.

Shire Pharmaceuticals
Group plc

In May 2000, we signed an agreement with Shire Pharmaceuticals Group under which Shire purchased from us the exclusive rights
to balsalazide, for use as a treatment for ulcerative colitis for Austria, Belgium, Denmark, Finland, France, Germany, Iceland, Republic of Ireland, Luxembourg, Norway, The Netherlands, Switzerland, Sweden and the United Kingdom. Under the
agreement, Shire agreed to pay us up to a total of approximately $24.0 million, including approximately $12.1 million in up-front fees and up to $12.0 million upon the achievement of certain milestones. In accordance with our license arrangement
with Biorex Laboratories Limited, our licensor, we share a portion of these payments with Biorex. In May 2000, Shire paid us $9.6 million of cash and $2.5 million by way of the issue of 160,546 new Shire ordinary shares which we subsequently sold.
In August 2000 Shire paid us $4.4 million in connection with the transfer to Shire of the United Kingdom product license for balsalazide. No such additional payments have been made to us by Shire since August 2000. During 2004, we recognized $3.5
million of revenue from collaborative agreements related to this agreement which had previously been deferred. We do not anticipate any future revenues under this agreement.

Zeria Pharmaceutical Co. Ltd.

In August 2001,
InKine Pharmaceutical Company, Inc., which we acquired in September 2005, licensed exclusive commercial rights in Japan to Visiclear® Tablets for colon cleansing to Zeria Pharmaceutical
Co., Ltd. of Tokyo, Japan. Zeria launched Visiclear in June 2007. Visiclear, or sodium phosphate monobasic monohydrate and sodium phosphate dibasic anhydrous, tablets are marketed in the United States under the trade name VISICOL®.

Co-Promotion Agreement with Eisai Inc.

In September 2007, we entered into a Co-Promotion Agreement with Eisai Inc. for Eisai to act as our exclusive co-promoter of Colazal 750 milligram
capsules in the United States and its territories. In February 2008 under the terms of this Agreement, we mutually agreed with Eisai to terminate this agreement as a result of the approval of three generic balsalazide capsule products on
December 28, 2007. During 2007 there were no amounts paid to Eisai under this Agreement.

Supply and Distribution Agreement with Watson Pharma, Inc.

On December 28, 2007, we announced that we entered into a Supply and Distribution Agreement with Watson Pharma, Inc., pursuant to which Watson will
be Salixs exclusive distributor to market and sell an authorized generic of Colazal (balsalazide disodium) Capsules 750 mg, Salixs anti-inflammatory drug approved for the treatment of mildly to moderately active ulcerative colitis, in
the United States. Watson agrees to use commercially reasonable efforts to sell authorized generic Colazal, and has sole discretion to establish prices and terms. Watson will pay Salix a portion of its profits for sales under the agreement, and
Salix will supply Watson with all its requirements for the product. The agreement terminates in October 2011, provided that either party may terminate immediately upon bankruptcy of the other, or for uncured breaches of the other party. Salix may
also terminate on 30 days notice if the agreement has become commercially unviable, if it obtains the right to prohibit other generics from being sold or if it ceases distribution of branded Colazal.

MANUFACTURING

We own no manufacturing facilities. We
have in the past used and plan to continue to use third-party manufacturers to produce material for use in clinical trials and for commercial product. This manufacturing strategy enables us to direct our financial resources to product in-licensing
and acquisition, product development, and sales and marketing efforts, without devoting resources to the time and cost associated with building and maintaining manufacturing facilities.

Currently, under long-term supply agreements, we use balsalazide drug substance (the active pharmaceutical ingredient in Colazal capsules) manufactured
by Omnichem s.a., a subsidiary of Ajinomoto in Belgium, and Pharmazell (formerly Noveon Pharma, GmbH) in Raubling, Germany. Also, under long-term supply agreements, balsalazide is encapsulated into Colazal drug product for us by Nexgen Pharma, inc.
(formerly Anabolic Laboratories) in Irvine, California. Bulk Colazal capsules are packaged into finished Colazal commercial bottles by Nexgen and Carton Service in Norris, Tennessee.

Under our supply agreement with Alfa Wassermann, Alfa Wassermann is obligated to supply us with bulk rifaximin drug substance (the active pharmaceutical
ingredient in Xifaxan tablets) until July 2014 or introduction of a generic product, whichever occurs first. Our supply of rifaximin drug substance is manufactured by ZaCh Systems (formerly Zambon) in Lonigo, Italy, and Aventis in Brindisi, Italy.
Under a long-term supply agreement, rifaximin is converted into Xifaxan drug product for us by Patheon, Inc. in Whitby, Ontario. Bulk Xifaxan tablets are packaged into finished Xifaxan commercial bottles by Pathoen and packaged into Xifaxan
commercial blister packs by Carton Service in Norris, Tennessee.

Under our long-term supply agreement with aaiPharma, aaiPharma produces
our commercial supply of 75 mg and 100 mg Azasan finished product. We are in the process of working with aaiPharma to qualify an additional Azasan drug product manufacturer.

Under our long-term supply agreement with Paddock Laboratories in Minneapolis, Minnesota, Paddock produces our commercial supply of finished product of
Anusol-HC Cream, Anusol-HC Suppositories and Proctocort Suppositories. In addition, through prior supply arrangements between King Pharmaceuticals and Crown Laboratories in Johnson City, Tennessee, Crown continues to produce our commercial supply of
Proctocort Cream finished product.

Under our long-term supply agreement with WellSpring Pharmaceuticals in Oakville, Ontario, WellSpring
produces our commercial supply of OsmoPrep finished product.

Under our long-term supply agreement with Norgine in Hengoed, Wales, Norgine
produces our commercial supply of MoviPrep pouches. We then supply Carton Service in Norris, Tennessee with these MoviPrep pouches for secondary packaging into finished commercial MoviPrep kits.

Merck has agreed to manufacture our commercial supply of Pepcid Oral Suspension and Diuril Oral Suspension through December 2008. We are in the process
of qualifying an alternate manufacturing site for commercial production of Pepcid OS and Diuril OS finished product.

##### Table of Contents

With respect to our products currently under development, namely our encapsulated granulated mesalamine,
our 1100 mg balsalazide tablet formulation and our 550 mg rifaximin tablet formulation, we plan to negotiate commercial supply agreements with the same manufacturers who supplied the drug substance and drug product for the supplies of the Phase III
clinical trial material.

SALES AND MARKETING

We currently market our products and intend, if approved by the FDA, to market future products to U.S. gastroenterologists through our own direct sales force. We enter into distribution relationships outside the United States and in markets
where a larger sales organization is appropriate. Currently, our sales and marketing staff consists of approximately 150 people, which we believe should also position us to sell additional products, if and when acquired and/or approved for U.S.
marketing. Because there is a relatively small number of gastroenterologists that write a majority of the prescriptions in our indications, we believe that the size of our sales force, is appropriate to reach our target physicians. Our sales force
consists of ninety-six employees who regularly call on approximately 11,000 gastroenterologists. We also have nine national account managers who regularly call on major drug wholesalers, managed care organizations, large retail chains, formularies
and related organizations. We believe we have created an attractive incentive program for our sales force that is based upon goals in prescription growth, market share achievement and customer service.

We cultivate relationships of trust and confidence with the high prescribing gastroenterologists in the United States. We use a variety of marketing
techniques to promote our products including sampling, journal advertising, promotional materials, specialty publications, coupons, money-back or product replacement guarantees, educational conferences and informational websites.

PATENTS AND PROPRIETARY RIGHTS

General

The patents for the balsalazide composition of matter and method of treating ulcerative colitis with balsalazide expired in July 2001 in the United
States; however, we were granted five years of new chemical entity data exclusivity for balsalazide until July 2005 and an extension of such patent under the Waxman-Hatch Act through July 2006. We also obtained patent extensions for the composition
of balsalazide in Italy and the United Kingdom until July 2006. We have filed applications for patents relating to additional indications using balsalazide and related chemical substances.

The patents for the rifaximin composition of matter (also covering a process of making rifaximin and using rifaximin to treat gastrointestinal infectious
diseases) expired in May 2001 in the United States and Canada. In May 2006, a U.S. patent (composition of matter and process patent that covers several physical states of rifaximin) was issued that extends the patent coverage of the currently
marketed form of rifaximin to May 22, 2024. Alfa Wasserman S.p.a., the patent owner, has licensed rights to rifaximin in the United States to Salix. In July 2006, Salix entered into an agreement with Cedars-Sinai Medical Center for the right to
use its patent and patent application relating to methods of diagnosis and treating irritable bowel syndrome and other disorders caused by small intestinal bacterial overgrowth.

The patent for the treatment of the intestinal tract with the granulated mesalamine product provides patent coverage to 2018.

The patent for balsalazide 1100 mg tablets provides patent coverage to 2018.

The patent for Visicol provides patent coverage to 2013.

The patent for OsmoPrep provides patent coverage to 2013. Additional patent protection is being sought on OsmoPrep that, if approved, will provide patent coverage to 2024.

The patent for MoviPrep provides patent coverage to 2024. This patent was issued by the USPTO in January 2007 and it contains composition of matter and
kit claims.

The patent for Sanvar expired in 2006; however, we will be applying for Patent Term Restoration.

Data Exclusivity

Rifaximin is a new
chemical entity, therefore, the FDA granted us five year new chemical entity exclusivity when it was approved in May 2004. Therefore, rifaximin has data exclusivity through May 2009.

Although the granulated mesalamine product is not a new chemical entity, it may be entitled to three years of exclusivity from the date of its approval
based on the new clinical investigations that have been required during the approval process. Such exclusivity would have the effect of preventing the FDA from approving an NDA for a granulated mesalamine product which relied upon the new clinical
investigation in our NDA for three years from the date of approval. The patent for the granulated mesalamine protects the product until 2018.

Sanvar is an orphan drug, therefore, the product will be entitled to orphan exclusivity for seven years beginning from the date of the approval of our NDA.

Azasan and the Anusol-HC and Proctocort product lines are mature products, thus, there are no available patent or exclusivity rights.

GOVERNMENT REGULATION

The research, testing, manufacture, marketing and distribution of drug
products are extensively regulated by governmental authorities in the United States and other countries. In the United States, drugs are subject to rigorous regulation by the FDA. The Federal Food, Drug and Cosmetic Act, as amended, and the
regulations promulgated thereunder, and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, record keeping, labeling, promotion and marketing and distribution of
pharmaceutical products. Failure to comply with applicable regulatory requirements may subject a company to administrative sanctions or judicially imposed sanctions such as civil penalties, criminal prosecution, injunctions, product seizure or
detention, product recalls, and total or partial suspension of product marketing and/or approvals. In addition, non-compliance may result in the FDAs refusal to approve pending NDAs or supplements to approved NDAs or in the withdrawal of an
NDA. Any such sanction could result in adverse publicity, which could have a material adverse effect on our business, financial conditions, and results of operation.

The steps ordinarily required before a new pharmaceutical product containing a new chemical entity may be marketed in the United States include: (1) preclinical laboratory tests, preclinical studies in animals
and formulation studies; (2) the submission to the FDA of a notice of claimed investigational exemption for a new drug or antibiotic, which must become effective before clinical testing may commence; (3) adequate and well-controlled
clinical human trials to establish the safety and efficacy of the drug for each indication; (4) the submission of an NDA to the FDA; and (5) FDA review and approval of the NDA prior to any commercial sale or shipment of the drug.
Preclinical tests include laboratory evaluation of product chemistry and formulation, as well as animal studies to assess the potential safety and efficacy of the product. Preclinical tests must be conducted in compliance with Good Laboratory
Practice regulations. The results of preclinical testing are submitted to the FDA as part of an IND. A 30-day waiting period after the filing of each IND is required prior to the commencement of clinical testing in humans. In addition, the FDA may,
at any time during this 30-day period or at any time thereafter, impose a clinical hold on proposed or ongoing clinical trials. If the FDA imposes a clinical hold, clinical trials cannot commence or recommence without FDA authorization and then only
under terms authorized by the FDA. In some instances, the IND application process can result in substantial delay and expense.

Clinical
trials to support NDAs are typically conducted in three sequential phases, but the phases may overlap. In Phase I, the initial introduction of the drug into healthy human subjects or patients, the drug is tested to assess metabolism,
pharmacokinetics and pharmacological actions and safety, including side effects associated with increasing doses. Phase II usually involves studies in a limited patient population to (1) assess the efficacy of the drug in specific, targeted
indications, (2) assess dosage tolerance and optimal dosage and (3) identify possible adverse effects and safety risks. If a compound is found to be potentially effective and to have an acceptable safety profile in



13

##### Table of Contents

Phase II evaluations, Phase III trials are undertaken to further demonstrate clinical efficacy and to further test for safety within an expanded patient
population at geographically dispersed clinical study sites. There can be no assurance that Phase I, Phase II or Phase III testing will be completed successfully within any specified time period, if at all, with respect to any of our products
subject to such testing.

After successful completion of the required clinical testing, generally an NDA is submitted. FDA approval of the
NDA is required before marketing may begin in the United States. The FDA reviews all NDAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA for filing. In such an event, the NDA must be
resubmitted with the additional information and, again, is subject to review before filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. The FDA generally has 10 months in which to review the NDA and
respond to the applicant. The review process is often significantly extended by FDA requests for additional information or clarification regarding information already provided in the submission. The FDA may refer the application to an appropriate
advisory committee, typically a panel of clinicians, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee. If the FDAs evaluation of
the NDA submission or manufacturing facilities is not favorable, the FDA may refuse to approve the NDA or issue a not approvable letter, outlining the deficiencies in the submission and often requiring additional testing or information. If FDA
evaluations of the NDA and the manufacturing facilities are favorable, the FDA may issue either an approval letter or an approvable letter, which usually contains a number of conditions that must be met in order to secure final approval of the NDA.
When and if those conditions have been met to the FDAs satisfaction, the FDA will issue an approval letter, authorizing commercial marketing of the drug for certain indications. Furthermore, approval may entail ongoing requirements for
post-marketing studies, and marketed products, manufacturers and manufacturing facilities are subject to continual review and periodic inspections. In addition, identification of certain side effects after a drug is on the market or the occurrence
of manufacturing problems could cause subsequent withdrawal of approval, reformulation of the drug, additional preclinical testing or clinical trials and changes in labeling of the product.

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a disease or condition that affects
populations of fewer than 200,000 individuals in the United States or a disease whose incidence rates number more than 200,000 where the sponsor establishes that it does not realistically anticipate that its product sales will be sufficient to
recover its costs. The sponsor that obtains the first marketing approval for a designated orphan drug for a given rare disease is eligible to receive marketing exclusivity for use of that drug for the orphan indication for a period of seven years.
Vapreotide acetate, rifaximin for the treatment of hepatic encephalopathy and Colazal for the treatment of mildly to moderately active ulcerative colitis in pediatric patients between 5 to 17 years of age have been granted orphan drug status.

Regulation of Drug Compounds Outside of the United States

Outside the United States, the ability to market a drug is contingent upon receiving marketing authorizations from the appropriate regulatory authorities. The requirements governing the conduct of clinical trials and
marketing authorization vary widely from country to country. Currently, foreign marketing authorizations are applied for at a national level, although within the European Union procedures are available to companies wishing to market a product in
more than one European Union member state. The foreign regulatory approval process includes all of the risks associated with FDA approval set forth above.

If and when necessary, we will choose the appropriate route of European regulatory filing to accomplish the most rapid regulatory approvals. However, the chosen regulatory strategy might not secure regulatory
approvals or approvals of our chosen product indications. Furthermore, we must obtain pricing approval in addition to regulatory approval prior to launching the product in the approving country. Failure to obtain pricing approval in a timely manner
or approval of pricing which would support an adequate return on investment or generate a sufficient margin to justify the economic risk might delay or prohibit the commercial launch of the product in those countries.

COMPETITION

Competition in our business is intense
and characterized by extensive research efforts and rapid technological progress. Technological developments by competitors, earlier regulatory approval for marketing competitive products,



14

##### Table of Contents

or superior marketing capabilities possessed by competitors could adversely affect the commercial potential of our products and could have a material adverse
effect on our revenue and results of operations. We believe that there are numerous pharmaceutical and biotechnology companies, including large well known pharmaceutical companies, as well as academic research groups throughout the world, engaged in
research and development efforts with respect to pharmaceutical products targeted at gastrointestinal diseases and conditions addressed by our current and potential products. In particular, we are aware of products in research or development by
competitors that address the diseases being targeted by our products. Developments by others might render our current and potential products obsolete or non-competitive. Competitors might be able to complete the development and regulatory approval
process sooner and, therefore, market their products earlier than us. Many of our competitors have substantially greater financial, marketing and personnel resources and development capabilities than we do.

For example, many large, well capitalized companies already offer products in the United States and Europe that target the indications for balsalazide,
including mesalamine and the granulated mesalamine product (GlaxoSmithKline plc, Giuliani S.p.A., Axcan Pharma, Inc., Solvay S.A., The Procter & Gamble Company and Shire Pharmaceuticals Group plc), sulfasalazine (Pharmacia &
Upjohn, Inc.), and olsalazine (Pharmacia & Upjohn, Inc.). Asacol, marketed by Proctor & Gamble, is currently the most prescribed product for the treatment of ulcerative colitis in the United States, and Shire recently introduced
once-a-day Lialda. In addition, on December 28, 2007, the Office of Generic Drugs approved three generic balsalazide capsule products.

Several prescription, liquid PEG products compete with Visicol, OsmoPrep and MoviPrep in the bowel cleansing market. These prescription products include Colyte, Golytely, Halflytely, and Nulytely (Braintree) and Trilyte (Schwarz Pharma).
Generic prescription, liquid PEG products are also available. An over-the-counter product, Fleets Phospho-Soda, also competes in the bowel cleansing market.

The most frequently prescribed product for treatment of travelers diarrhea in the United
States currently is ciprofloxacin, commonly known as Cipro® and marketed by Bayer AG. The most frequently prescribed products that compete with Azasan are Imuran®, marketed by Prometheus Laboratories, Inc., and its various generics and Purinethol®, marketed by GATE Pharmaceuticals, and its
various generics. The most frequently prescribed products that compete with Anusol-HC and Proctocort are AnaMantle HC, marketed by Bradley Pharmaceuticals; Analpram HC, marketed by Ferndale Laboratories; Proctofoam-HC and Proctocream-HC, marketed by
Schwartz Pharma; Procto-Kit, marketed by Ranbaxy Pharmaceuticals; and various generics.

EMPLOYEES

As of December 31, 2007, we had approximately 270 full-time employees. We believe that our future success will depend in part on our continued
ability to attract, hire, and retain qualified personnel, including sales and marketing personnel in particular. Competition for such personnel is intense, and there can be no assurance that we will be able to identify, attract, and retain such
personnel in the future. None of our employees are represented by a labor union. We have not experienced any work stoppages and consider our relations with our employees to be good.

Item 1A. Risk Factors

This report contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those discussed in this report. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and elsewhere in this report and in any
documents incorporated in this report by reference.

If any of the following risks, or other risks not presently known to us or that
we currently believe to not be significant, develop into actual events, then our business, financial condition, results of operations or prospects could be materially adversely affected. If that happens, the market price of our common stock could
decline, and stockholders may lose all or part of their investment.

Future sales of Colazal will be significantly less than historical sales due to
the approval of three generic competitors.

Historically we have derived a majority of our revenue from sales of Colazal. On
December 28, 2007, the Office of Generic Drugs, or OGD, approved three generic balsalazide capsule products, and we announced that we had



15

##### Table of Contents

entered into an agreement with Watson Pharma, Inc. to market and sell an authorized generic of Colazal. Watson will pay Salix a portion of its profits for
sales under the agreement, and Salix will supply Watson with all its requirements for the product. The price competition among the generic firms has resulted in dramatic price erosion compared to pricing prior to the generic approvals, and we expect
that the market share that Watson obtains will be significantly less profitable than Colazals previous market share. In addition, we have implemented various programs in 2008 that attempt to reduce the market share lost to the generic
products, however these programs will reduce the profitability of Colazal sales in 2008 and thereafter. As a result, we expect the future sales of Colazal to be significantly less than historical sales.

In the fourth quarter of 2007, we recorded a $34.6 million reserve which is our estimate of Colazal previously sold to wholesalers that may be returned
to us under our return policy as a result of these generic approvals, based on data currently available to us. Since we have limited experience on the actual effect that the generics will have on Colazal demand, this estimate could be adjusted
higher or lower in future periods based on actual returns.

The combined effect of Colazals reduction in market share, the price
erosion in the 5-ASA market and the limited expected contribution from Watsons share of the generic market will have a material adverse effect on our business, financial condition and results of operations. In addition, it is possible that
additional generics could be approved, further increasing competition and pricing pressure.

We expect to be unprofitable and experience negative cash
flow during 2008, and we may need additional capital.

Due to the generic approvals discussed above, we will be unprofitable and have
negative cash flow during 2008. We believe that our current cash and cash equivalents together with cash generated from the sale of our products will be sufficient to fund our operations for 2008. Our future capital requirements will depend on many
factors, including but not limited to:

| | - |  | ----------------------------------------------------

We believe that we will be able to return to a positive cash flow position without requiring additional capital based on our current projections. However these projections may change due to changes in the factors
discussed above, or other factors. If we need additional capital, we might seek additional debt or equity financing or both to fund our operations or acquisitions. If we incur more debt, we might be restricted in our ability to raise additional
capital and might be subject to financial and restrictive covenants. If we issued additional equity, our stockholders could suffer dilution. We might also enter into additional collaborative arrangements that could provide us with additional funding
in the form of equity, debt, licensing, milestone and/or royalty payments. We might not be able to enter into such arrangements or raise any additional funds on terms favorable to us or at all. Our common stock is likely to decrease in value if the
market believes that we will be unable to return to profitability, or that we will be required to raise additional capital.

Our credit
facility contains various representations, warranties and affirmative, negative and financial covenants customary for financings of this type. The financial covenants include a leverage test and a fixed charge test. We were in compliance with these
covenants at December 31, 2007. However, based on our current projections for 2008, we could fall out of compliance with the financial covenants at some point during 2008, unless we obtain a waiver or amend the facility, which we are discussing
with the lender. In the event a waiver or amendment is not obtained, the $15.0 million currently outstanding on the credit facility would be immediately due if one or more of the covenants are violated.

Future sales of Xifaxan and our other marketed products might be less than expected.

We currently market and sell nine primary products, with a majority of our historical revenue derived from sales of Colazal. We expect Xifaxan, which was
launched in mid-2004, OsmoPrep, which we acquired in connection with our acquisition of InKine in September 2005, and MoviPrep, which we acquired from Norgine in December 2005, to be growing and significant sources of revenue in the future. If sales
of our marketed products decline or if we experience product returns significantly in excess of estimated amounts recorded, particularly with respect to Xifaxan, OsmoPrep and MoviPrep, it would have a material adverse effect on our business,
financial condition and results of operations.

The degree of market acceptance of our products among physicians, patients, healthcare
payors and the medical community will depend upon a number of factors including:



| |  |  | the timing of regulatory approvals and product launches by us or competitors, such as the launch of Lialda, and including any generic or over-the-counter
competitors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | perceptions by physicians and other members of the healthcare community regarding the safety and efficacy of the products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | price increases, and the price of our products relative to other drugs or competing treatments;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | patient and physician demand;
| | - |  | -----------------------------



| |  |  | adverse side effects or unfavorable publicity concerning our products or other drugs in our class;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the results of product development efforts for new indications;
| | - |  | ---------------------------------------------------------------



| |  |  | the scope and timing of additional marketing approvals and favorable reimbursement programs for expanded uses;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | availability of sufficient commercial quantities of the products; and
| | - |  | ---------------------------------------------------------------------



| |  |  | our success in getting other companies to distribute our products outside of the U.S. gastroenterology market.
| | - |  | --------------------------------------------------------------------------------------------------------------

Our ability to increase revenue in the future will depend in part on our success in in-licensing or acquiring additional pharmaceutical products.

We currently intend to in-license or acquire pharmaceutical products, like vapreotide acetate, that have been developed beyond the initial discovery phase
and for which late-stage human clinical data is already available, or like Pepcid Oral Suspension, that have already received regulatory approval. These kinds of pharmaceutical products might not be available to us on attractive terms or at all. To
the extent we acquire rights to additional products, we might incur significant additional expense in connection with the development and, if approved by the FDA, marketing of these products. In addition, our license agreement with Alfa Wassermann
provides that we may not promote, distribute or sell any antibiotic product that competes with Xifaxan in the United States and Canada until mid-2009, thereby limiting our ability to acquire, develop or market other antibiotic products.

Regulatory approval of our product candidates is time-consuming, expensive and uncertain, and could result in unexpectedly high expenses and delay our ability to
sell our products.

Development of our products are subject to extensive regulation by governmental authorities in the United States and
other countries. This regulation could require us to incur significant unexpected expenses or delay or limit our ability to sell our product candidates, including specifically granulated mesalamine, metoclopramide-Zydis and balsalazide disodium
tablets, our product candidates that are farthest along in the regulatory approval process. As an example, FDA approval of MoviPrep was delayed from May until August 2006 to resolve regulatory issues, and in early 2008, the FDA announced that
because of its large workload it might not meet its target dates to respond to NDA submissions.

Our clinical studies might be delayed or
halted, or additional studies might be required, for various reasons, including:



| |  |  | the drug is not effective;
| | - |  | --------------------------



| |  |  | patients experience severe side effects during treatment;
| | - |  | ---------------------------------------------------------



17



---

##### Table of Contents

| |  |  | appropriate patients do not enroll in the studies at the rate expected, as has been the case with our Xifaxan Phase III trial in Thailand for the prevention of
travelers diarrhea;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | drug supplies are not sufficient to treat the patients in the studies; or
| | - |  | -------------------------------------------------------------------------



| |  |  | we decide to modify the drug during testing.
| | - |  | --------------------------------------------

If regulatory approval of any product is granted, it will be limited to those indications for which the product has been shown to be safe and effective, as demonstrated to the FDAs satisfaction through clinical studies. We are
developing granulated mesalamine and balsalazide disodium tablets as treatments for ulcerative colitis and vapreotide acetate as a treatment for acute esophageal variceal bleeding, as well as studying Xifaxan for other indications. The FDA may never
approve these compounds in these indications, which would mean we cannot market these compounds for use in these indications.

Regulatory approval, even
if granted, might entail ongoing requirements or restrictions on marketing that could increase our expenses and limit revenue.

Approval
might entail ongoing requirements for post-marketing studies, or limit how or to whom we can sell our products. Even if regulatory approval is obtained, such as with Colazal, Xifaxan Visicol, OsmoPrep, and MoviPrep, labeling and promotional
activities are subject to continual scrutiny by the FDA and state regulatory agencies and, in some circumstances, the Federal Trade Commission. FDA enforcement policy prohibits the marketing of approved products for unapproved, or off-label, uses.
These regulations and the FDAs interpretation of them might increase our expenses, impair our ability to effectively market our products, and limit our revenue.

Failure to comply with manufacturing regulation could harm us financially and could hurt our reputation.

We and our third-party manufacturers are also required to comply with the applicable FDA current Good Manufacturing Practices, or cGMP, regulations, which include requirements relating to quality control and quality assurance, as well as
the corresponding maintenance of records and documentation. Further, manufacturing facilities must be approved by the FDA before they can be used to manufacture our products, and they are subject to additional FDA inspection. Manufacturing
regulations can increase our expenses and delay production, either of which could reduce our margins. In addition, if we fail to comply with any of the FDAs continuing regulations, we could be subject to reputational harm and sanctions,
including:



| |  |  | delays, warning letters and fines;
| | - |  | ----------------------------------



| |  |  | product recalls or seizures and injunctions on sales;
| | - |  | -----------------------------------------------------



| |  |  | refusal of the FDA to review pending applications;
| | - |  | --------------------------------------------------



| |  |  | total or partial suspension of production;
| | - |  | ------------------------------------------



| |  |  | withdrawals of previously approved marketing applications; and
| | - |  | --------------------------------------------------------------



| |  |  | civil penalties and criminal prosecutions.
| | - |  | ------------------------------------------

In addition, the occurrence of manufacturing problems could cause subsequent withdrawal of approval, reformulation of the drug, additional testing or changes in labeling of the product.

Our intellectual property rights might not afford us with meaningful protection.

The intellectual property rights protecting our products might not afford us with meaningful protection from generic and other competition. In addition, because our strategy is to in-license or acquire pharmaceutical
products which typically have been discovered and initially researched by others, future products might have limited or no remaining patent protection due to the time elapsed since their discovery. Competitors could also design around any of our
intellectual property or otherwise design competitive products that do not infringe our intellectual property.

Any litigation that we
become involved in to enforce intellectual property rights could result in substantial cost to us. In addition, claims by others that we infringe their intellectual property could be costly. Our patent or other



18

##### Table of Contents

proprietary rights related to our products might conflict with the current or future intellectual property rights of others. Litigation or patent
interference proceedings, either of which could result in substantial cost to us, might be necessary to defend any patents to which we have rights and our other proprietary rights or to determine the scope and validity of other parties
proprietary rights. The defense of patent and intellectual property claims is both costly and time-consuming, even if the outcome is favorable. Any adverse outcome could subject us to significant liabilities to third parties, require disputed rights
to be licensed from third parties, or require us to cease selling one or more of our products. We might not be able to obtain a license to any third-party technology that we require to conduct our business, or, if obtainable, that technology might
not be available at a reasonable cost.

Upon patent expiration, our drugs could be subject to generic competition, which could negatively
affect our pricing and sales volume. As noted above in Future sales of Colazal will be significantly less than historical sales due to the approval of three generic competitors, this has already happened to balsalazide capsules.

Patent applications relating to rifaxamin compositions and related chemical substances were filed together with Alfa Wasserman and issued
in May 2006. This patent extends patent coverage to 2024. In January 2007, the United States Patent and Trademark Office issued a patent covering composition of matter and kit claims for MoviPrep. The MoviPrep patent provides coverage to September
2024. The patent for Visicol and OsmoPrep will expire in 2013. Additional patent protection is being sought for OsmoPrep that, if approved, will provide patent coverage to 2024. The patent for the treatment of the intestinal tract with the
granulated mesalamine product will provide patent coverage to 2018. The patent for Sanvar expired in 2006; however, we will be applying for patent Term Restoration. There is no assurance that these patents or the patent term restoration will be
issued or granted, respectively. Patent expiration dates listed herein, unless otherwise noted, are for U.S. patents and assume there are no patent term adjustments, extensions or other adverse events that could affect the term or scope of a patent.

Rifaximin is a new chemical entity and was granted a five-year new chemical entity exclusivity by the FDA when it was approved in May
2004. Rifaximin, therefore, has data exclusivity to May 2009. Similarly, Sanvar is a new chemical entity and will be entitled to data exclusivity for five years beginning from the date of the approval of our NDA. In June and September 2007 we
submitted additional Supplements to our Citizen Petition originally filed in April 2005, requesting the director of the Office of Generic Drugs of the Food and Drug Administration adopt guidance applicable to orally administered, locally-acting
gastrointestinal drug products prior to approval of any generic versions of such drugs. The FDA rejected our Citizens Petition and all Supplemental filings in December 2007, allowing the three generic versions of balsalazide capsules to be approved
and making additional generic versions of our products easier to approve that we had hoped.

Because Azasan, Anusol-HC and Proctocort are
mature products there are no patents or data exclusivity rights available, which subjects us to greater risk of generic competition for those products.

We also rely on trade secrets, proprietary know-how and technological advances, which we seek to protect, in part, through confidentiality agreements with collaborative partners, employees and consultants. These
agreements might be breached and we might not have adequate remedies for any such breach. In addition, our trade secrets and proprietary know-how might otherwise become known or be independently developed by others.

We could be exposed to significant product liability claims that could prevent or interfere with our product commercialization efforts.

We might be subjected to product liability claims that arise through the testing, manufacturing, marketing and sale of our products. These claims could
expose us to significant liabilities that could prevent or interfere with our product commercialization efforts. Product liability claims could require us to spend significant time and money in litigation or to pay significant damages. Although we
currently maintain liability coverage for both clinical trials and the commercialization of our products, it is possible that this coverage will be insufficient to satisfy any liabilities that may arise. In the future, we might not be able to obtain
adequate coverage at an acceptable cost or might be unable to obtain adequate coverage at all.

Intense competition might render our products noncompetitive or obsolete.

Competition in our business is intense and characterized by extensive research efforts and rapid technological progress. Technological developments by
competitors, regulatory approval for marketing competitive products, including potential generic or over-the-counter products, or superior marketing resources possessed by competitors could adversely affect the commercial potential of our products
and could have a material adverse effect on our revenue and results of operations. We believe that there are numerous pharmaceutical and biotechnology companies, including large well-known pharmaceutical companies, as well as academic research
groups throughout the world, engaged in research and development efforts with respect to pharmaceutical products targeted at gastrointestinal diseases and conditions addressed by our current and potential products. In particular, we are aware of
products in research or development by competitors that address the diseases being targeted by our products. Developments by others might render our current and potential products obsolete or noncompetitive. Competitors might be able to complete the
development and regulatory approval process sooner and, therefore, market their products earlier than we can.

Many of our competitors have
substantially greater financial, marketing and personnel resources and development capabilities than we do. For example, many large, well-capitalized companies already offer products in the United States and Europe that target the indications for:



| |  |  | Colazal, including Asacol (Proctor & Gamble), sulfasalazine (Pfizer), Dipentum (UCB Pharma Inc.), Pentasa (Shire Pharmaceuticals Group, plc), once-a-day
Lialda (Shire), and three generic balsalazide capsule products;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Xifaxan as approved (travelers diarrhea), including ciprofloxacin, commonly known as Cipro (Bayer AG);
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | Visicol, OsmoPrep and MoviPrep, including Colyte, Golytely, Halflytely, and Nulytely (Braintree) and Trilyte (Schwarz Pharma) and Fleets Phospho-Soda; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Xifaxan under development, including Lotronex® (Prometheus)
and Zelnorm® (Novartis) for IBS.
| | - |  | --------------------------------------------------------------------------------------------

In addition, other products
are in research or development by competitors that address the diseases and diagnostic procedures being targeted by these and our other products.

If
third-party payors do not provide coverage or reimburse patients for our products, our ability to derive revenues will suffer.

Our
success will depend in part on the extent to which government and health administration authorities, private health insurers and other third-party payors will pay for our products. Reimbursement for newly approved healthcare products is uncertain.
In the United States and elsewhere, third-party payors, such as Medicaid, are increasingly challenging the prices charged for medical products and services. Government and other third-party payors are increasingly attempting to contain healthcare
costs by limiting both coverage and the level of reimbursement for new therapeutic products. In the United States, a number of legislative and regulatory proposals aimed at changing the healthcare system have been proposed in recent years. In
addition, an increasing emphasis on managed care in the United States has and will continue to increase pressure on pharmaceutical pricing. While we cannot predict whether legislative or regulatory proposals will be adopted or what effect those
proposals or managed care efforts, including those relating to Medicaid payments, might have on our business, the announcement and/or adoption of such proposals or efforts could increase costs and reduce or eliminate profit margins. Third-party
insurance coverage might not be available to patients for our products. If government and other third-party payors do not provide adequate coverage and reimbursement levels for our products, the market acceptance of these products might be reduced.

We are dependent on third parties to manufacture our products.

We have limited experience and capabilities in manufacturing pharmaceutical products. We do not generally expect to engage directly in the manufacturing of products, but instead contract with others for these
services. A limited number of manufacturers exist which are capable of manufacturing our marketed products and our product candidates. We might fail to contract with the necessary manufacturers or might contract with manufacturers on terms that may
not be entirely acceptable to us. Our manufacturing strategy presents the following risks:



| |  |  | the manufacture of products might be difficult to scale up when required and result in delays, inefficiencies and poor or low yields of quality products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



20

##### Table of Contents

| |  |  | some of our contracts contain purchase commitments that require us to make minimum purchases that might exceed needs or limit the ability to negotiate with other
manufacturers, which might increase costs;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cost of manufacturing certain products might make them prohibitively expensive;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | delays in scale-up to commercial quantities and any change in manufacturers could delay clinical studies, regulatory submissions and commercialization of our
products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | manufacturers are subject to the FDAs cGMP regulations and similar foreign standards, and we do not have control over compliance with these regulations by the
third-party manufacturers; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if we need to change manufacturers, FDA and comparable foreign regulators would require new testing and compliance inspections and the new manufacturers would have
to be educated in the processes necessary for the production of our products.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our results of operations might fluctuate from period
to period, and a failure to meet the expectations of investors or the financial community at large could result in a decline in our stock price.

Our results of operations might fluctuate significantly on a quarterly and annual basis due to, among other factors:



| |  |  | the timing of regulatory approvals and product launches by us or competitors, including potential generic or over-the-counter competitors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the level of revenue generated by commercialized products, including potential increased purchases of inventory by wholesalers in anticipation of potential price
increases or introductions of new dosages or bottle sizes, and subsequent lower than expected revenue as the inventory is used;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of any up-front payments that might be required in connection with any future acquisition of product rights;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of milestone payments that might be required to our current or future licensors;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | fluctuations in our development and other costs in connection with ongoing product development programs;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | the level of marketing and other expenses required in connection with product launches and ongoing product growth;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of the acquisition and integration of businesses, assets, products and technologies; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | general and industry-specific business and economic conditions.
| | - |  | ---------------------------------------------------------------

Our stock price is volatile.

Our stock price has been extremely volatile and might continue to be,
making owning our stock risky. Between January 1, 2005 and March 10, 2008, the price of a share of our common stock varied from a low of $5.53 to a high of $22.79, as adjusted for the 3-for-2 stock split effected in July 2004.

The securities markets have experienced significant price and volume fluctuations unrelated to the performance of particular companies, as a result of
the current credit crisis. In addition, the market prices of the common stock of many publicly traded pharmaceutical and biotechnology companies have in the past been and can in the future be expected to be especially volatile. Announcements of
prescription trends, technological innovations or new products by us or our competitors, generic approvals, developments or disputes concerning proprietary rights, publicity regarding actual or potential medical results relating to products under
development by us or our competitors, regulatory developments in both the United States and other countries, public concern as to the safety of pharmaceutical products, and economic and other external factors, as well as period-to-period
fluctuations in financial results, might have a significant impact on the market price of our common stock.

Antitakeover provisions could discourage a
takeover that stockholders consider to be in their best interests or prevent the removal of our current directors and management.

We
have adopted a number of provisions that could have antitakeover effects or prevent the removal of our current directors and management. We have adopted a stockholder protection rights plan, commonly referred to as a

##### Table of Contents

poison pill. The rights plan is intended to deter an attempt to acquire us in a manner or on terms not approved by our board of directors. The rights plan
will not prevent an acquisition that is approved by our board of directors. We believe our rights plan assisted in our successful defense against a hostile takeover bid earlier in 2003. Our charter authorizes our board of directors to determine the
terms of up to 5,000,000 shares of undesignated preferred stock and issue them without stockholder approval. The issuance of preferred stock could make it more difficult for a third party to acquire, or discourage a third party from acquiring,
voting control in order to remove our current directors and management. Our bylaws also eliminate the ability of the stockholders to act by written consent without a meeting or make proposals at stockholder meetings without giving us advance written
notice, which could hinder the ability of stockholders to quickly take action that might be opposed by management. These provisions could make more difficult the removal of current directors and management or a takeover of Salix, even if these
events could be beneficial to stockholders. These provisions could also limit the price that investors might be willing to pay for our common stock.

On March 10, 2008 the closing price for the common stock as reported on the Nasdaq Global
Market was $5.64. As of March 10, 2008 there were 238 stockholders of record, which excludes stockholders whose shares were held in nominee or street name by brokers.

The securities markets have from time to time experienced significant price and volume fluctuations unrelated to the operating performance of particular
companies. Our stock has been particularly volatile, including for example the approximate 21.8% single-day drop on December 28, 2007, when three generic versions of our drug Colazal were approved. The market prices of the common stock of Salix
and many publicly traded pharmaceutical and biotechnology companies have in the past and can in the future be expected to be especially volatile. Announcements of technological innovations or new products by us or our competitors, developments or
disputes concerning proprietary rights, publicity regarding actual or potential medical results relating to products under development by us or our competitors, regulatory developments in both the United States and other countries, public concern as
to the safety of pharmaceutical products and economic and other external factors, as well as period-to-period fluctuations in our financial results, might have a significant impact on the market price of our common stock.

each calendar year, which closely approximates the last day of the respective fiscal year of the Company. The historical stock performance presented below is not intended to and may not be indicative of future stock performance.

In July 2004, we effected a three-for-two stock split of our common stock. As a result of the
stock split, stockholders as of the record date of June 30, 2004 received one additional common share for every two shares held on the record date. The payment date for the additional shares was July 13, 2004.

Dividend Policy

We have never declared or paid cash
dividends on our common stock. We currently expect to retain future earnings, if any, for use in the operation and expansion of business and do not anticipate paying any cash dividends in the foreseeable future.

Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

We are a specialty pharmaceutical company dedicated to acquiring, developing and commercializing prescription drugs used in the
treatment of a variety of gastrointestinal diseases, which are those affecting the digestive tract. Our strategy is to



| |  |  | identify and acquire rights to products that we believe have potential for near-term regulatory approval or are already approved;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | apply our regulatory, product development, and sales and marketing expertise to commercialize these products; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | use our 150-member specialty sales and marketing team focused on high-prescribing U.S. gastroenterologists to sell our products.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

Our current products demonstrate our ability to execute this strategy. As of December 31, 2007, our primary products were:



| |  |  | XIFAXAN® (rifaximin) Tablets 200 mg;
| | - |  | ------------------------------------



| |  |  | OSMOPREP (sodium phosphate monobasic monohydrate, USP and sodium phosphate dibasic anhydrous, USP) Tablets;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | MOVIPREP® (PEG 3350, Sodium Sulfate, Sodium Chloride,
Potassium Chloride, Sodium Ascorbate and Ascorbic Acid for Oral Solution);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | COLAZAL® (balsalazide disodium) Capsules 750 mg;
| | - |  | ------------------------------------------------



| |  |  | VISICOL® (sodium phosphate monobasic monohydrate, USP, and
sodium phosphate dibasic anhydrous, USP) Tablets;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | AZASAN® Azathioprine Tablets, USP, 75/100 mg;
| | - |  | ---------------------------------------------



| |  |  | ANUSOL-HC® 2.5% (Hydrocortisone Cream, USP), ANUSOL-HC® 25 mg Suppository (Hydrocortisone Acetate);
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | PROCTOCORT® Cream (Hydrocortisone Cream, USP) 1% and
PROCTOCORT® Suppository (Hydrocortisone Acetate Rectal Suppositories) 30 mg;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | PEPCID® (famotidine) for Oral Suspension; and
| | - |  | ---------------------------------------------



| |  |  | Oral Suspension DIURIL® (Chlorothiazide).
| | - |  | -----------------------------------------

We currently market our products, and intend, if approved by the FDA, to market future products to U.S.
gastroenterologists through our own direct sales force. We enter into distribution relationships outside the United States and in certain markets in the U.S. where a larger sales organization is appropriate. Currently, our sales and marketing staff
consists of approximately 150 people.

We generate revenue primarily by selling our products, namely prescription drugs, to pharmaceutical
wholesalers. These direct customers resell and distribute our products to and through pharmacies to patients who have had our products prescribed by doctors. Because demand for our products originates with doctors, our sales force calls on
high-prescribing specialists, primarily gastroenterologists, and we monitor new and total prescriptions for our products as key performance indicators for our business.

Prescriptions result in our products being used by patients, requiring our direct customers to purchase more products to replenish their inventory. However, our revenue might fluctuate from quarter to quarter due to
other factors, such as increased buying by wholesalers in anticipation of a price increase or because of the introduction of new products. Revenue could be less than anticipated in subsequent quarters as wholesalers increased inventory is used
up. For example, wholesalers made initial stocking purchases of OsmoPrep when it was launched in second quarter 2006 and MoviPrep when it was launched in the third quarter of 2006. Also, 2006 Colazal revenue was slightly lower than in the comparable
periods in 2005 even though prescriptions increased in 2006.

##### Table of Contents

In December 2000, we established our own field sales force to market Colazal in the United States.
Currently, this sales force has approximately 100 sales representatives in the field. Although the creation of an independent sales organization involved substantial costs, we believe that the financial returns from our direct product sales have
been and will continue to be more favorable to us than those from the indirect sale of products through marketing partners. In addition, we intend to enter into distribution relationships outside the United States and in markets where a larger sales
organization is appropriate.

Our primary product candidates under development and their status are as follows:

CRITICAL ACCOUNTING POLICIES

General

Our discussion and analysis of our financial condition and results of operations are based
upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and
judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to sales of our products,
bad debts, inventories, investments, intangible assets and legal issues. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis
for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results might differ materially from these estimates under different assumptions or conditions.

Methodologies used and assumptions selected by management in making these estimates, as well as the related disclosures, have been reviewed by and
discussed with the Audit Committee of our Board of Directors.

We believe the following critical accounting policies affect our more
significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We recognize revenue in accordance with the SECs Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements as
amended by Staff Accounting Bulletin No. 104 (together, SAB 101), and FASB Statement No. 48 Revenue Recognition When Right of Return Exists (SFAS 48). SAB 101 states that revenue should not be recognized
until it is realized or realizable and earned. Revenue is realized or realizable and earned when all of the following criteria are met: (a) persuasive evidence of an arrangement exists; (b) delivery has occurred or services have been
rendered; (c) the sellers price to the buyer is fixed and determinable; and (d) collectibility is reasonably assured.

SFAS
48 states that revenue from sales transactions where the buyer has the right to return the product shall be recognized at the time of sale only if (1) the sellers price to the buyer is substantially fixed or determinable at the date



28

of sale, (2) the buyer has paid the seller, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of the product,
(3) the buyers obligation to the seller would not be changed in the event of theft or physical destruction or damage of the product, (4) the buyer acquiring the product for resale has economic substance apart from that provided by
the seller, (5) the seller does not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (6) the amount of future returns can be reasonably estimated. We recognize revenues for
product sales at the time title and risk of loss are transferred to the customer, and the other criteria of SAB 101 and SFAS 48 are satisfied, which is generally at the time products are shipped. Our net product revenue represents our total revenues
less allowances for customer credits, including estimated discounts, rebates, chargebacks, and product returns.

We establish allowances
for estimated rebates, chargebacks and product returns based on numerous qualitative and quantitative factors, including:



| |  |  | the number of and specific contractual terms of agreements with customers;
| | - |  | --------------------------------------------------------------------------



| |  |  | estimated levels of inventory in the distribution channel;
| | - |  | ----------------------------------------------------------



| |  |  | historical rebates, chargebacks and returns of products;
| | - |  | --------------------------------------------------------



| |  |  | direct communication with customers;
| | - |  | ------------------------------------



| |  |  | anticipated introduction of competitive products or generics;
| | - |  | -------------------------------------------------------------



| |  |  | anticipated pricing strategy changes by Salix and/or its competitors;
| | - |  | ---------------------------------------------------------------------



| |  |  | analysis of prescription data gathered by a third-party prescription data provider;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the impact of changes in state and federal regulations; and
| | - |  | -----------------------------------------------------------



| |  |  | estimated remaining shelf life of products.
| | - |  | -------------------------------------------

In our analyses, we use prescription data purchased from a third-party data provider to develop estimates of historical inventory channel pull-through. We utilize an internal analysis to compare historical net product shipments to estimated
historical prescriptions written. Based on that analysis, we develop an estimate of the quantity of product in the channel which may be subject to various rebate, chargeback and product return exposures. At least quarterly for each product line, we
prepare an internal estimate of ending inventory units in the distribution channel by adding estimated inventory in the channel at the beginning of the period, plus net product shipments for the period, less estimated prescriptions written for the
period. Based on that analysis, we develop an estimate of the quantity of product in the channel that might be subject to various rebate, chargeback and product return exposures. This is done for each product line by applying a rate of historical
activity for rebates, chargebacks and product returns, adjusted for relevant quantitative and qualitative factors discussed above, to the potential exposed product estimated to be in the distribution channel. Internal forecasts that are utilized to
calculate the estimated number of months in the channel are regularly adjusted based on input from members of our sales, marketing and operations groups. The adjusted forecasts take into account numerous factors including, but not limited to, new
product introductions, direct communication with customers and potential product expiry issues.

Consistent with industry practice, we
periodically offer promotional discounts to our existing customer base. These discounts are calculated as a percentage of the current published list price and are treated as off-invoice allowances. Accordingly, the discounts are recorded as a
reduction of revenue in the period that the program is offered. In addition to promotional discounts, at the time that we implement a price increase, we generally offer our existing customer base an opportunity to purchase a limited quantity of
product at the previous list price. Shipments resulting from these programs generally are not in excess of ordinary levels, therefore, we recognize the related revenue upon shipment and include the shipments in estimating our various product related
allowances. In the event we determine that these shipments represent purchases of inventory in excess of ordinary levels for a given wholesaler, the potential impact on product returns exposure would be specifically evaluated and reflected as a
reduction in revenue at the time of such shipments.

Allowances for estimated rebates and chargebacks were $9.9 million and $8.0 million as
of December 31, 2007 and 2006, respectively. These allowances reflect an estimate of our liability for items such as rebates due to various



29

##### Table of Contents

governmental organizations under the Medicare/Medicaid regulations, rebates due to managed care organizations under specific contracts and chargebacks due to
various organizations purchasing certain of our products through federal contracts and/or group purchasing agreements. We estimate our liability for rebates and chargebacks at each reporting period based on a methodology of applying the relevant
quantitative and qualitative assumptions discussed above. Due to the subjectivity of our accrual estimates for rebates and chargebacks, we prepare various sensitivity analyses to ensure our final estimate is within a reasonable range as well as
review prior period activity to ensure that our methodology continues to be appropriate. Had a change in one or more variables in the analyses (utilization rates, contract modifications, etc.) resulted in an additional percentage point change in the
trailing average of estimated chargeback and rebate activity in 2007, we would have recorded an adjustment to revenues of approximately $3.1 million, or 1.0%, for the year.

Allowances for product returns were $43.1 million and $6.1 million as of December 31, 2007 and 2006, respectively. These allowances reflect
an estimate of our liability for product that may be returned by the original purchaser in accordance with our stated return policy. The balance at December 31, 2007 includes the $34.6 million charge recorded in the fourth quarter of 2007
reflecting our estimate of Colazal that may be returned to us under our return policy as a result of the approval of three generic balsalazide capsule products by the Office of Generic Drugs on December 28, 2007. We estimate our liability for
product returns at each reporting period based on historical return rates, the estimated inventory in the channel, and the other factors discussed above. Due to the subjectivity of our accrual estimates for product returns, we prepare various
sensitivity analyses to ensure our final estimate is within a reasonable range as well as review prior period activity to ensure that our methodology is still reasonable. A change in assumptions that resulted in a 10% change in forecasted return
rates for all products other than Colazal would have resulted in a change in total product returns liability at December 31, 2007 of approximately $4.5 million and a corresponding change in 2007 net product revenue of less than 2.0%.

Colazal, our balsalazide disodium capsule, has historically accounted for a majority of the Companys revenue. On December 28,
2007, the Office of Generic Drugs, or OGD, approved three generic balsalazide capsule products. As a result of these generic approvals, the Company expects the future sales of Colazal to be significantly less than historical sales of Colazal. In the
fourth quarter of 2007, the Company recorded a $34.6 million reserve which is an estimate of the Companys liability for Colazal that may be returned by the original purchaser in accordance with the Companys stated return policy as a
result of these generic approvals. This estimate was developed based on the following estimates:



| |  |  | our estimate of the quantity and expiration dates of Colazal inventory in the distribution channel based on historical net product shipments less estimated
historical prescriptions written;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our estimate of future demand for Colazal based on the actual erosion of product demand for several comparable products that were previously genericized, and the
most recent demand for Colazal prior to the generic approvals;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the actual demand for Colazal experienced during 2008 subsequent to the generic approvals;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | our estimate of potential cannibalization of Colazal demand by our 1100mg balsalazide tablet which we expect to launch during 2008 if approved by the FDA;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our estimate of the generic market that will be obtained by Watson; and
| | - |  | -----------------------------------------------------------------------



| |  |  | other factors.
| | - |  | --------------

Due to the
subjectivity of this estimate, the Company prepares various sensitivity analyses to ensure the Companys final estimate is within a reasonable range. A change in assumptions that resulted in a 10% change in the quantity of Colazal inventory in
the distribution channel would have resulted in a change in the Colazal return reserve of approximately $8.2 million and a corresponding change in 2007 net product revenue of approximately 3.5%. A change in assumptions that resulted in a 10% change
in the estimated future demand of Colazal would have resulted in a change in the Colazal return reserve of approximately $2.6 million and a corresponding change in 2007 net product revenue of approximately 1.1%.

For the years ended December 31, 2007 and 2006, our absolute exposure for rebates, chargebacks and product returns has grown primarily as a result
of increased sales of our existing products, the approval of new products and the



30

##### Table of Contents

acquisition of products, and also in 2007 as a result of the approval of generic balsalazide capsule products. Accordingly, reductions to revenue and
corresponding increases to allowance accounts have likewise increased. The provision for these revenue-reducing items as a percentage of gross product revenue in the year ended December 31, 2007 and 2006 was 9.7% and 8.8% for rebates,
chargebacks and discounts and was 3.3% and 3.4% for product returns excluding the Colazal return reserve, respectively. The Colazal return reserve was 11.2% of gross product revenue in 2007.

Inventories

Raw materials, work-in-process and
finished goods inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out cost method) or market. In evaluating whether inventory is stated at the lower of cost or market, management considers such factors
as the amount of inventory on hand and in the distribution channel, estimated time required to sell such inventory, remaining shelf life, and current and expected market conditions, including levels of competition, including generic competition.
Inventory at December 31, 2007 consisted of $7.5 million of raw materials, $3.6 million of work-in-process, and $6.6 million of finished goods. Inventory at December 31, 2006 consisted of $14.4 million of raw materials, $2.5 million of
work in process and $8.2 million of finished goods. As of December 31, 2007, we had recorded inventory reserves totaling $0.8 million, compared to $0.7 million as of December 31, 2006, to reduce inventories to their net realizable value.

Intangible Assets and Goodwill

The
Companys intangible assets consist of license agreements, product rights and other identifiable intangible assets, which result from product and business acquisitions. Goodwill represents the excess purchase price over the fair value of assets
acquired and liabilities assumed in a business combination.

When the Company makes product acquisitions that include license agreements,
product rights and other identifiable intangible assets, it records the purchase price of such intangibles, along with the value of the product-related liabilities that we assume, as intangible assets. The Company allocates the aggregate purchase
price to the fair value of the various tangible and intangible assets in order to determine the appropriate carrying value of the acquired assets and then amortizes the cost of the intangible assets as an expense in the consolidated statements of
operations over the estimated economic useful life of the related assets. In accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long Lived Assets, the Company assesses
the impairment of identifiable intangible assets whenever events or changes in circumstances indicate that the carrying value might not be recoverable. The Company believes the following factors could trigger an impairment review: significant
underperformance relative to expected historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for our overall business, and significant negative industry or economic trends.

In assessing the recoverability of its intangible assets, the Company must make assumptions regarding estimated future cash flows and
other factors. If the estimated undiscounted future cash flows do not exceed the carrying value of the intangible assets, the Company must determine the fair value of the intangible assets. If the fair value of the intangible assets is less than the
carrying value, the Company will recognize an impairment loss equal to the difference. The Company reviews goodwill for impairment on an annual basis, and goodwill and other intangible assets for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable.

The Company assesses impairment of goodwill on an
annual basis in accordance with Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets.

In November 2003, the Company acquired from aaiPharma LLC for $2.0 million the exclusive right to sell 25, 75 and 100 milligram dosage strengths of azathioprine tablets in North America under the name Azasan. The purchase price was fully
allocated to product rights and related intangibles and is being amortized over a period of ten years. Although Azasan does not have any patent protection, the Company believes ten years is an appropriate amortization period based on established
product history and managements experience. At December 31, 2007 and 2006, accumulated amortization for the Azasan intangible was $0.8 million and $0.6 million, respectively.

In June 2004, the Company acquired the exclusive U.S. rights to Anusol-HC 2.5% (hydrocortisone Cream USP), Anusol-HC 25 mg Suppository (Hydrocortisone
Acetate), Proctocort Cream (Hydrocortisone Cream USP) 1% and

##### Table of Contents

Proctocort Suppositories (Hydrocortisone Acetate Rectal Suppositories, 30 mg) from King Pharmaceuticals, Inc. for $13.0 million. The purchase price was fully
allocated to product rights and related intangibles and is being amortized over a period of ten years. Although Anusol-HC and Proctocort do not have any patent protection, the Company believes ten years is an appropriate amortization period based on
established product sales history and managements experience. At December 31, 2007 and 2006, accumulated amortization for the King product intangibles was $4.6 million and $3.3 million, respectively.

In September 2005, the Company acquired InKine Pharmaceutical Company, Inc. for $210.0 million. We allocated $74.0 million of the purchase price to
in-process research and development, $9.3 million to net assets acquired and $37.0 million to specifically identifiable product rights and related intangibles with an ongoing economic benefit to us. The Company allocated the remaining $89.7 million
to goodwill, which is not being amortized. The InKine product rights and related intangibles are being amortized over an average period of 14 years, which the Company believes is an appropriate amortization period due to the products patent
protections and the estimated economic lives of the product rights and related intangibles. At December 31, 2007 and 2006, accumulated amortization for the InKine intangibles was $6.8 million and $3.8 million, respectively.

In December 2005, the Company entered into a License and Supply Agreement with Norgine B.V., granting Salix the exclusive right to sell a
patent-protected, liquid PEG bowel cleansing product, NRL 944, in the United States. In August 2006, the Company received Food and Drug Administration marketing approval for NRL 944 under the branded name of MoviPrep. In January 2007 the United
States Patent Office issued a patent providing coverage to September 1, 2024. In August 2006, pursuant to the terms of the Agreement, Salix made a $15.1 million payment to Norgine. The Company is amortizing the milestone payment over a period
of 17.3 years, which the Company believes is an appropriate amortization period due to the products patent protection and the estimated economic life of the related intangible. At December 31, 2007 and 2006, accumulated amortization for
the MoviPrep intangible was $1.2 million and $0.4 million.

In February 2007, the Company entered into a Master Purchase and Sale and
License Agreement with Merck & Co., Inc., to purchase the U.S. prescription pharmaceutical product rights to Pepcid Oral Suspension and Diuril Oral Suspension from Merck. The Company paid Merck $55.0 million at the closing of the
transaction. The purchase price was fully allocated to product rights and related intangibles, and is being amortized over a period of 15 years. Although Pepcid and Diuril do not have any patent protection, the Company believes 15 years is an
appropriate amortization period based on established product history and management experience. At December 31, 2007, accumulated amortization for the Merck products was $3.2 million.

Allowance for Uncollectible Accounts

Based on a
review of specific customer balances, industry experience and the current economic environment, we currently reserve for specific past due accounts that may represent collection concerns plus a percentage of our outstanding trade accounts receivable
balance as an allowance for uncollectible accounts, which at December 31, 2007 and 2006 was approximately $3.1 million and $2.7 million, respectively. Refer to Schedule IIValuation and Qualifying Accounts for a roll-forward of
the allowance for uncollectible accounts.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities from date of purchase of three months or less to be cash equivalents. The Company maintains its cash and cash equivalents in several different
financial instruments with various banks and brokerage houses. This diversification of risk is consistent with Company policy to maintain liquidity and ensure the safety of principal. At December 31, 2007, cash and cash equivalents consisted
primarily of demand deposits, overnight investments in Eurodollars, and money market funds. The Company has not experienced any loss of principal or liquidity in any of its cash and cash equivalents subsequent to year-end through March 13,
2008.

Research and Development

In
accordance with its policy, the Company expenses research and development costs, both internal and externally contracted, as incurred. The Company estimates certain externally contracted development activities to align the related

expense with the level of progress achieved and services rendered during the period. As of December 31, 2007 and 2006, the net asset related to on-going
research and development activities was $8.9 million and $2.1 million, respectively.

Revenues totaled $235.8 million, $208.5 million and $154.9 million for 2007, 2006 and 2005,
respectively. Revenues for the year ended December 31, 2007 included net product revenues of $232.9 million and revenues from collaborative agreements of $2.9 million. Revenues for the year ended December 31, 2006 consisted solely of net
product revenues. Revenues for the year ended December 31, 2005 included net product revenue of $154.7 million and revenues from collaborative agreements of $0.2 million.

Net product revenues for 2007 were $232.9 million, compared to $208.5 million for 2006, and $154.7 million for 2005. The net product revenue increase
from 2006 to 2007 was primarily due to:



| |  |  | price increases on our products;
| | - |  | --------------------------------



| |  |  | increased sales of Xifaxan;
| | - |  | ---------------------------



| |  |  | forty-one weeks of sales for Pepcid, which was acquired during February 2007;
| | - |  | -----------------------------------------------------------------------------



| |  |  | increased Colazal sales, offset by the Colazal return reserve recorded as a result of the approval of three generic balsalazide capsule products on
December 28, 2007;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | $2.2 million in sales to Watson Pharma, Inc. during the fourth quarter of 2007 in connection with their launch of the authorized generic; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a full year of sales for OsmoPrep and MoviPrep, which were launched during the second and fourth quarters of 2006, respectively; offset by
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reduced sales of Visicol.
| | - |  | -------------------------

Total
estimated prescription growth from 2006 to 2007 was 1% for Colazal, 35% for Xifaxan, and 98% for our purgatives.

On December 28,
2007, the Office of Generic Drugs approved three generic balsalazide capsule products. As a result of these generic approvals, the Company expects the future sales of Colazal to be significantly less than historical sales of Colazal. In the fourth
quarter of 2007, the Company recorded a $34.6 million reserve as a reduction of net product revenues. This reserve represents an estimate of the Companys liability for Colazal that may be

##### Table of Contents

returned by the original purchaser in accordance with the Companys stated return policy as a result of these generic approvals. This estimate was
developed based on the following estimates:



| |  |  | our estimate of the quantity and expiration dates of Colazal inventory in the distribution channel based on historical net product shipments less estimated
historical prescriptions written;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our estimate of future demand for Colazal based on the actual erosion of product demand for several comparable products that were previously genericized, and the
most recent demand for Colazal prior to the generic approvals;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the actual demand for Colazal experienced during 2008 subsequent to the generic approvals;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | our estimate of potential cannibalization of Colazal demand by our 1100mg balsalazide tablet which we expect to launch during 2008 if approved by the FDA;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our estimate of the generic market that will be obtained by Watson; and
| | - |  | -----------------------------------------------------------------------



| |  |  | other factors.
| | - |  | --------------

Due to the
subjectivity of this estimate, the Company prepares various sensitivity analyses to ensure the Companys final estimate is within a reasonable range. A change in assumptions that resulted in a 10% change in the quantity of Colazal inventory in
the distribution channel would have resulted in a change in the Colazal return reserve of approximately $8.2 million and a corresponding change in 2007 net product revenue of approximately 3.5%. A change in assumptions that resulted in a 10% change
in the estimated future demand of Colazal would have resulted in a change in the Colazal return reserve of approximately $2.6 million and a corresponding change in 2007 net product revenue of approximately 1.1%.

The net product revenue increase from 2005 to 2006 was primarily due to:



| |  |  | price increases on our products;
| | - |  | --------------------------------



| |  |  | increased Colazal prescriptions, offset by a draw-down of wholesaler inventories during 2006; and
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | increased sales of Xifaxan; offset by
| | - |  | -------------------------------------



| |  |  | increases in revenue-reducing items from 2005 to 2006 due to increases in allowances for managed care agreements as a result of increased product sales and the
allowance for product returns associated with Colazal, Visicol, Anusol and Proctocort.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Total estimated prescription
growth from 2005 to 2006 was 10% for Colazal, 35% for our purgatives and 118% for Xifaxan.

Revenues from collaborative agreements for 2007 consists of an upfront payment of $1.5 million upon execution of an agreement to license exclusive rights to market OsmoPrep, under the name DIACOL, in 28 territories in Europe to
Dr. Falk Pharma GmbH of Freiberg, Germany; a $1.0 million milestone payment from Zeria Pharmaceutical Co., Ltd. of Tokyo, Japan as a result of their receipt of marketing approval of Visiclear® Tablets, for colon cleansing in Japan; and $0.4 million upon execution of an agreement to license exclusive rights to market OSMOPREP in France to Mayoly
 Spindler S.A.S of Chatou, France. Revenues from collaborative agreements for 2007 include $12,000 in royalty income from sales of Visiclear® by Zeria. We did not receive any revenues
from collaborative agreements during 2006. Revenue from collaborative agreements for 2005 was $0.2 million.

Costs and Expenses

Total costs and expenses were $223.9 million, $178.2 million and $216.0 million for 2007, 2006 and 2005, respectively. Higher operating
expenses in absolute terms for 2007 compared to 2006 were due primarily to increased research and development activities; increased cost of products sold related to the corresponding increase in product revenue; increased selling, general and
administrative expenses due to the expansion of our infrastructure; costs related to OsmoPrep and MoviPrep, which were launched during the second and fourth quarters of 2006, respectively; and the acquisition of Pepcid during February 2007.
Excluding the September 2005 one-time charge of $74.0 million for the write-off of in-process research and development associated with the acquisition of InKine, our higher operating



34

##### Table of Contents

expenses in absolute terms for 2006 compared to 2005 were due primarily to increased research and development activities, increased cost of products sold
related to the corresponding increase in product revenues, and increased selling, general and administrative expenses due to the expansion of our sales force in connection with the InKine merger and the launches of OsmoPrep and MoviPrep.

Cost of Products Sold

Cost of
products sold were $55.0 million, $41.4 million and $34.2 million for 2007, 2006 and 2005, respectively. Gross margin on total product revenue, excluding $8.6 million, $4.9 million and $2.3 million in amortization of product rights and intangible
assets for 2007, 2006 and 2005 was 76%, 80% and 78% in 2007, 2006 and 2005, respectively. The increase in cost of products sold in absolute dollars from 2006 to 2007 was primarily due to increased sales of Colazal and Xifaxan, a full year of sales
for OsmoPrep and MoviPrep which were launched during the second and fourth quarters of 2006, respectively, and the acquisition of Pepcid during February 2007. The lower gross margin in 2007 is a result of the return reserve recorded in the fourth
quarter of 2007 for Colazal as a result of the approval of three generic balsalazide capsule products, which reduced net product revenues and the gross margin for 2007.

The increase in cost of products sold from 2005 to 2006 was due primarily to increased sales of Xifaxan and Visicol and the additions of OsmoPrep and MoviPrep during the second and third quarters, respectively. The
lower gross margin in 2005 was primarily due to a one-time write-off of $2.7 million of obsolete inventories associated with the initial launch of Xifaxan. Cost of products sold does not include amortization of product rights and intangibles. Refer
to Critical Accounting Policies  Intangible Assets and Goodwill above.

Fees and Costs Related to License Agreements

Fees and costs related to license agreements were $1.9 million, $1.3 million and
$0.1 million in 2007, 2006 and 2005, respectively, and relate primarily to payments made to Debiovision, Cedars-Sinai, Biorex and Alfa Wassermann under the terms of their respective license agreements. The amount for 2007 also includes payments of
$1.5 million to Clinical Development Capital, the successor licensor of Visicol® and OsmoPrep, for its share of the German, Japanese and French milestone revenue of $2.9 million recognized
during 2007.

Research and Development

Research and development expense was $71.9 million, $47.9 million and $34.5 million for 2007, 2006 and 2005, respectively. The increase in research and development expenses was due primarily to the expansion of our
Colazal life cycle management program through initiatives to strengthen and support our 1100mg balsalazide tablet submission completed in July 2007, studies of granulated mesalamine, and ongoing late-stage studies to expand the Xifaxan label.

The increase in research and development expenses from 2005 to 2006 was due primarily to the expansion of our Colazal life cycle
management program through initiatives to strengthen and support our 1100mg balsalazide tablet submission, our Colazal pediatric exclusivity filing and the costs associated with ongoing late-stage studies to expand the Xifaxan label. To date, we
have incurred research and development expense of approximately $60.3 million for balsalazide, $71.1 million for rifaximin and $27.9 million for granulated mesalamine. Due to the risks and uncertainties of the drug development and regulatory
approval process, research and development expenditures are difficult to forecast and subject to unexpected increases. As disclosed in Note 2 in the Notes to Consolidated Financial Statements, due to increased development activities and the way in
which many of our long-term development contracts are structured, in 2006 we refined our process of estimating development activities to more closely align expenses with the level of progress achieved. We expect research and development costs to
increase in absolute terms as we pursue additional indications and formulations for balsalazide and rifaximin, and continue to develop granulated mesalamine, and if and when we acquire new products.

Selling, General and Administrative

Selling, general and administrative expenses were $86.5 million, $82.6 million and $70.8 million for 2007, 2006 and 2005, respectively. The slight increase in absolute dollars from 2006 to 2007 was primarily due to the expansion of our
infrastructure related to OsmoPrep and MoviPrep, which were launched during the second and fourth quarters of 2006, respectively, the acquisition of Pepcid during February 2007, and the write-off of Colazal samples, offset by reduced spending on the
launch of OsmoPrep.

##### Table of Contents

The increase in absolute dollars from 2005 to 2006 was primarily due to launch and training activities
associated with our two new purgative products, OsmoPrep and MoviPrep, and the expansion of our sales force and infrastructure subsequent to the InKine merger.

Interest and Other Income, Net

Interest and other income, net was $3.3 million, $2.6 million and
$1.2 million in 2007, 2006 and 2005, respectively. Interest and other income, net for 2007 includes $1.2 million received as final settlement of a legal matter initiated by InKine prior to our acquisition of InKine. This increase in interest and
other income, net is offset by a decrease in interest and other income, net primarily due to interest expense of $0.2 million on our credit facility discussed below. The increase from 2005 to 2006 was primarily due to higher average daily cash
balances and increased short-term interest rates.

Provision for Income Tax

Income tax expense was $7.0 million, $1.4 million and $0.7 million in 2007, 2006 and 2005, respectively. Our effective tax rate was 45.8%, 4.2% and
(1.2%) in 2007, 2006 and 2005, respectively, due to utilization of net operating loss carryforwards. The higher than expected rate in 2007 was due to an increase in the valuation allowance for deferred taxes related to the $34.6 million reserve
related to Colazal recorded in the fourth quarter.

At December 31, 2007, 2006 and 2005, we had U.S. federal net operating loss
carryforwards of approximately $37.0 million, $111.1 million and $128.7 million, respectively. These carryforwards will expire on various dates beginning in 2020 through 2024 if not utilized. Utilization of the federal net operating loss and credit
carryforwards may be subject to a substantial annual limitation due to the change in ownership provisions of the Internal Revenue Code. The annual limitation might result in the expiration of net operating losses and credits before
utilization.

Quarterly Results of Operations

See Note 11 of Notes to Consolidated Financial Statements for a presentation of our quarterly results of operations for the years ended December 31, 2007 and 2006.

LIQUIDITY AND CAPITAL RESOURCES

From inception until
first achieving profitability in the third quarter of 2004, we financed product development, operations and capital expenditures primarily from public and private sales of equity securities and from funding arrangements with collaborative partners.
Since launching Colazal in January 2001, net product revenue has been a growing source of cash. As of December 31, 2007, we had $111.3 million in cash, cash equivalents and short-term investments compared to $76.5 million as of
December 31, 2006.

Net cash provided by operating activities was $76.1 million, $17.9 million and $3.0 million in 2007, 2006, and
2005, respectively. Positive operating cash flows in 2007 was primarily attributable to increased earnings before the Colazal return reserve noncash charge, and reduced accounts receivable and inventory balances in 2007. Positive operating cash
flows in 2006 was primarily attributable to increased earnings, partially offset by increased accounts receivable balances due to increased sales in December 2006 and decreased accounts payable and accrued liability balances. Positive operating cash
flows in 2005 were primarily attributable to increased earnings, excluding the impact of non-cash flow items including in-process research and development and depreciation and amortization, partially offset by increased accounts receivable and other
current assets.

Net cash used in investing activities was $59.4 million in 2007 and was primarily attributable to the acquisition of
Pepcid for $55.0 million and the purchase of property and equipment. Net cash used in investing activities was $12.8 million in 2006 and was primarily attributable to the acquisition of MoviPrep and the purchase of property and equipment, partially
offset by $1.0 million of investments that matured or were called by the issuers. Net cash provided by investing activities was $9.5 million in 2005 and was primarily attributable to proceeds from the maturity of investments and net cash acquired in
the InKine acquisition, partially offset by the purchase of property and equipment and product rights.

##### Table of Contents

Net cash provided by financing activities of $18.1 million in 2007 was attributable to $15.0 million of
borrowings under our credit facility entered into in February 2007, and the exercise of stock options. Net cash provided by financing activities of $4.2 million and $6.5 million in 2006 and 2005, respectively, was attributable to the exercise of
stock options.

As of December 31, 2007, we had non-cancelable purchase order commitments for inventory purchases of approximately
$9.6 million. We anticipate significant expenditures related to our on-going sales, marketing, product launch and development efforts associated with 1100mg balsalazide tablets, Xifaxan, Visicol, Azasan, Anusol-HC, Proctocort, OsmoPrep, MoviPrep,
Pepcid Oral Suspension and granulated mesalamine. To the extent we acquire rights to additional products, we will incur additional expenditures.

Our contractual commitments for non-cancelable purchase commitments of inventory, minimum lease obligations for all non-cancelable operating leases, and minimum capital lease obligations (including interest) as of December 31, 2007 are
as follows (in thousands):

In February 2007, we entered into a $100.0 million revolving credit facility that matures in
February 2012. At December 31, 2007, $15.0 million was outstanding under the credit facility. Virtually all of our assets and those of our subsidiaries secure our obligations under the credit facility. The credit facility may be used for
working capital, capital expenditures, acquisitions and other general corporate purposes.

The credit facility bears interest at a rate per
annum equal to, at our option, either (a) a base rate equal to the higher of (i) the Federal Funds Rate plus 1/2 of 1% and (ii) the Bank of America prime rate, or (b) a Eurodollar rate (based on LIBOR), plus, in each case, a
percentage rate that fluctuates, based on the ratio of our funded debt to EBITDA (income before income taxes plus interest expense and depreciation and amortization), from 0.00% to 0.75% for base rate borrowings and 1.00% to 1.75% for Eurodollar
rate borrowings. The rate as of December 31, 2007 on our outstanding borrowings was 6.00%.

The credit facility contains various
representations, warranties and affirmative, negative and financial covenants customary for financings of this type. The financial covenants include a leverage test and a fixed charge test. We were in compliance with these covenants at
December 31, 2007. However, based on our current projections for 2008, we could fall out of compliance with the financial covenants at some point during 2008, unless we obtain a waiver or amend the facility, which we are discussing with the
lender. In the event a waiver or amendment is not obtained, the $15.0 million currently outstanding on the credit facility would be immediately due if one or more of the covenants are violated.

As of December 31, 2007, we had an accumulated deficit of $104.7 million and cash and cash equivalent balances of $111.3 million. We expect to be
unprofitable and experience negative cash flow during 2008, due to the approval of three generic balsalazide capsule products.We believe our cash and cash equivalent balances should be sufficient to satisfy our cash requirements for the
foreseeable future. Based on our current projections, we believe that we will be able to return to a positive cash flow position without requiring additional capital. However, our actual cash needs might vary materially from those now planned
because of a number of factors, including the status of competitive products, including potential generics, intellectual property risks, our success selling products, the results of research and development activities, FDA and foreign regulatory
processes, establishment of and change in collaborative relationships, technological advances by us and other pharmaceutical companies, the actual amount of Colazal returns we receive compared to our current estimates, our ability to maintain our
current credit facility, and whether we acquire rights to additional products. We might seek additional debt or equity financing or both to fund our operations or acquisitions. If we incur more debt, we might be restricted in our ability to raise
additional capital and might be subject

to financial and restrictive covenants. If we issue additional equity, our stockholders could suffer dilution. We might also enter into additional
collaborative arrangements that could provide us with additional funding in the form of equity, debt, licensing, milestone and/or royalty payments. We might not be able to enter into such arrangements or raise any additional funds on terms favorable
to us or at all.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In December 2007, the FASB issued SFAS No. 141 (revised 2007) Business Combinations (SFAS 141R). SFAS 141R is effective for fiscal years beginning on or after December 15, 2008, which means that
we will adopt SFAS 141R in our fiscal year 2009. SFAS 141R replaces SFAS 141 Business Combinations and requires that the acquisition method of accounting (which SFAS 141 called the purchase method) be used for all business combinations,
as well as for an acquirer to be identified for each business combination. SFAS 141R establishes principles and requirements for how the acquirer: (i) recognizes and measures in its financial statements the identifiable assets acquired, the
liabilities assumed, and any noncontrolling interest in the acquiree; (ii) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and (iii) determines what information to disclose to
enable users of financial statements to evaluate the nature and financial affects of the business combination. We are currently evaluating the impact of adoption of SFAS 141R on our consolidated financial position, results of operations and cash
flows.

In December 2007, the FASB issued SFAS No. 160 Noncontrolling Interests in Consolidated Financial Statements, an
amendment of ARB No. 51 (SFAS 160). SFAS 160 is effective for fiscal years beginning on or after December 15, 2008, which means that we will adopt SFAS 160 in our fiscal year 2009. This statement amends ARB 51 to establish accounting
and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 changes accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and
classified as a component of equity in the Consolidated Financial Statements. SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. All other requirements of SFAS 160 shall be applied
prospectively. We do not believe the adoption of SFAS 160 will have a material impact on our consolidated financial position, results of operations and cash flows.

In February 2007, the FASB issued SFAS No. 159 The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS 159 permits entities to choose, at specified election
dates, to measure eligible items at fair value (the Fair Value Option). Unrealized gains and losses on items for which the Fair Value Option has been elected are reported in earnings. The Fair Value Option is applied instrument by
instrument (with certain exceptions), is irrevocable (unless a new election date occurs) and is applied only to an entire instrument. The effect of the first remeasurement to fair value is reported as a cumulative-effect adjustment to the opening
balance of retained earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We do not expect the adoption of SFAS 159 to have a material impact on our consolidated financial position, results of operations or cash
flows.

In September 2006, the FASB issued SFAS No. 157 Fair Value Measurements (SFAS 157), which defines fair value,
establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and expands disclosures about fair value measurements. This Statement applies to other accounting pronouncements that require or permit
fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. SFAS 157 is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. In February 2008, the FASB released FSP No. FAS 157-2. FSP No. FAS 157-2 defers the effective date of FASB 157 for one year for nonfinancial assets and nonfinancial liabilities
that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. It does not defer recognition and disclosure requirements for financial assets and financial liabilities, or for nonfinancial assets and nonfinancial
liabilities that are remeasured at least annually. We do not expect the adoption of SFAS 157 to have a material impact on our consolidated financial position, results of operations or cash flows.

CAUTIONARY STATEMENT

We operate in a highly
competitive environment that involves a number of risks, some of which are beyond our control. The following statement highlights some of these risks. For more detail, see Item 1A  Risk Factors.

##### Table of Contents

Statements contained in this Form 10-K that are not historical facts are or might constitute
forward-looking statements under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Although we believe the expectations reflected in such forward-looking statements are based on reasonable assumptions, our
expectations might not be attained. Forward-looking statements involve known and unknown risks that could cause actual results to differ materially from expected results. Factors that could cause actual results to differ materially from our
expectations expressed in the report include, among others: our need to return to profitability; intense competition, including from generics; the high cost and uncertainty of the research, clinical trials and other development activities involving
pharmaceutical products; the unpredictability of the duration and results of regulatory review of New Drug Applications and Investigational New Drug Applications; the possible impairment of, or inability to obtain intellectual property rights and
the costs of obtaining such rights from third parties; our dependence on our first nine pharmaceutical products, particularly Colazal and Xifaxan, and the uncertainty of market acceptance of our products; the uncertainty of obtaining, and our
dependence on, third parties to manufacture and sell our products; and results of future litigation and other risk factors detailed from time to time in our other SEC filings.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Our purchases of raw materials are
denominated primarily in Euros. Translation into our reporting currency, the U.S. dollar, has not historically had a material impact on our financial position. Additionally, our net assets denominated in currencies other than the U.S. dollar have
not historically exposed us to material risk associated with fluctuations in currency rates. Given these facts, we have not considered it necessary to use foreign currency contracts or other derivative instruments to manage changes in currency
rates. However, these circumstances might change.

Item 8. Financial Statements and Supplementary Data

The information required by this Item is set forth in
the Consolidated Financial Statements and Notes thereto beginning at page F-1 of this Report.

applicable.

Item 9A. Control and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) are designed only to provide reasonable assurance that
information to be disclosed in our Exchange Act Reports is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms. As of the end of the period covered by this report, the Company carried out
an evaluation, under the supervision and with the participation of the Companys management, including the Companys President and Chief Executive Officer and Senior VP, Finance and Administration and Chief Financial Officer, of the
effectiveness of the Companys disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e). Based upon this evaluation, the Companys President and Chief Executive Officer and Senior VP, Finance and Administration and Chief
Financial Officer have concluded that our disclosure controls and procedures are effective to provide the reasonable assurance discussed above.

Managements Report on Internal Control over Financial Reporting

Our management is responsible for establishing and
maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is designed to provide reasonable assurance to our management and board of
directors regarding the preparation and fair presentation of published financial statements. A control system, no matter how well designed and operated, can only provide reasonable, not absolute, assurance that the objectives of the control system
are met and must reflect the fact that there are resource constraints that require management to consider the benefits of internal controls relative to their costs. Because of these inherent limitations, management does not expect that our internal
controls over financial

reporting will prevent all error and all fraud. Under the supervision and with the participation of our management, including our CEO and our Senior VP,
Finance and Administration and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework inInternal Control  Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework inInternal Control  Integrated Framework, our management concluded that our internal control over financial reporting was
effective as of December 31, 2007.

The effectiveness of our internal control over financial reporting as of December 31, 2007,
has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included on page F-2 herein.

Changes in Internal Control over Financial Reporting

There was no change in our internal controls over financial reporting
during the fourth quarter of the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To Board of Directors and Stockholders of

Salix Pharmaceuticals, Ltd.

In our opinion, the
accompanying consolidated balance sheet and the related consolidated statements of operations, stockholders equity and cash flows present fairly, in all material respects, the financial position of Salix Pharmaceuticals, Ltd at
December 31, 2007, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement
schedule listed in the index appearing under item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations
of the Treadway Commission (COSO). The Companys management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting, included in Managements Report on Internal Control over Financial Reporting appearing in Item 9A. Our responsibility is to express opinions on these financial statements, on the
financial statement schedule and on the Companys internal control over financial reporting based on our integrated audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all
material respects. Our audit of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinions.

As discussed in Note 2 to the consolidated financial statements, the Company
changed the manner in which it accounts for uncertain tax positions in 2007.

A companys internal control over financial reporting is
a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company
are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control
over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the
financial statements referred to above present fairly, in all material respects, the consolidated financial position of Salix Pharmaceuticals, Ltd. at December 31, 2006, and the consolidated results of its operations and its cash flows for each
of the two years in the period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Salix Pharmaceuticals, Ltd.s internal control over financial reporting as of December 31, 2006, based on criteria
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 9, 2007 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

ON INTERNAL CONTROL

The Board of Directors and Stockholders of

Salix Pharmaceuticals, Ltd.

We have audited managements assessment, included in the accompanying Managements Report on Internal Control over Financial
Reporting, that Salix Pharmaceuticals, Ltd. maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (the COSO criteria). Salix Pharmaceuticals, Ltd.s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting. Our responsibility is to express an opinion on managements assessment and an opinion on the effectiveness of the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal
control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being
made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets
that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, managements assessment that Salix Pharmaceuticals, Ltd. maintained
effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Salix Pharmaceuticals, Ltd. maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2006, based on the COSO criteria.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Salix Pharmaceuticals, Ltd. as of December 31, 2006, and the related consolidated statements of operations,
stockholders equity, and cash flows for each of the two years in the period ended December 31, 2006 of Salix Pharmaceuticals, Ltd. and our report dated March 9, 2007 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

December 31, 2007

(1) ORGANIZATION AND BASIS
OF PRESENTATION

Salix Pharmaceuticals, Ltd., a Delaware corporation (Salix or the Company), is a specialty
pharmaceutical company dedicated to acquiring, developing and commercializing prescription drugs used in the treatment of a variety of gastrointestinal diseases, which are those affecting the digestive tract.

These consolidated financial statements are stated in U.S. dollars and are prepared under accounting principles generally accepted in the United States.
The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company balances and transactions have been eliminated in the consolidation.

The accompanying consolidated financial statements include all adjustments that, in the opinion of management, are necessary for a fair presentation of
financial position, results of operations, and cash flows.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of consolidated
financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying
notes. Actual results could differ from those estimates.

Revenue Recognition

The Company recognizes revenue in accordance with the SECs Staff Accounting Bulletin No. 101, Revenue Recognition in Financial
Statements as amended by Staff Accounting Bulletin No. 104 (together, SAB 101), and FASB Statement No. 48 Revenue Recognition When Right of Return Exists (SFAS 48). SAB 101 states that revenue
should not be recognized until it is realized or realizable and earned. Revenue is realized or realizable and earned when all of the following criteria are met: (a) persuasive evidence of an arrangement exists; (b) delivery has occurred or
services have been rendered; (c) the sellers price to the buyer is fixed or determinable; and (d) collectibility is reasonably assured.

SFAS 48 states that revenue from sales transactions where the buyer has the right to return the product shall be recognized at the time of sale only if (1) the sellers price to the buyer is substantially
fixed or determinable at the date of sale, (2) the buyer has paid the seller, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of the product, (3) the buyers obligation to the seller would
not be changed in the event of theft or physical destruction or damage of the product, (4) the buyer acquiring the product for resale has economic substance apart from that provided by the seller, (5) the seller does not have significant
obligations for future performance to directly bring about resale of the product by the buyer, and (6) the amount of future returns can be reasonably estimated. The Company recognizes revenues for product sales at the time title and risk of
loss are transferred to the customer, and the other criteria of SAB 101 and SFAS 48 are satisfied, which is generally at the time products are shipped. The Companys net product revenue represents the Companys total revenues less
allowances for customer credits, including estimated discounts, rebates, chargebacks, and product returns.

The Company establishes
allowances for estimated rebates, chargebacks and product returns based on numerous qualitative and quantitative factors, including:



| |  |  | the number of and specific contractual terms of agreements with customers;
| | - |  | --------------------------------------------------------------------------



| |  |  | estimated levels of inventory in the distribution channel;
| | - |  | ----------------------------------------------------------



| |  |  | historical rebates, chargebacks and returns of products;
| | - |  | --------------------------------------------------------

| |  |  | direct communication with customers;
| | - |  | ------------------------------------



| |  |  | anticipated introduction of competitive products or generics;
| | - |  | -------------------------------------------------------------



| |  |  | anticipated pricing strategy changes by the Company and/or its competitors;
| | - |  | ---------------------------------------------------------------------------



| |  |  | analysis of prescription data gathered by a third-party prescription data provider;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the impact of changes in state and federal regulations; and
| | - |  | -----------------------------------------------------------



| |  |  | estimated remaining shelf life of products.
| | - |  | -------------------------------------------

In its analyses, the Company uses prescription data purchased from a third-party data provider to develop estimates of historical inventory channel pull-through. The Company utilizes an internal analysis to compare historical net product
shipments to estimated historical prescriptions written. Based on that analysis, it develops an estimate of the quantity of product in the channel which may be subject to various rebate, chargeback and product return exposures. At least quarterly
for each product line, the Company prepares an internal estimate of ending inventory units in the distribution channel by adding estimated inventory in the channel at the beginning of the period, plus net product shipments for the period, less
estimated prescriptions written for the period. Based on that analysis, the Company develops an estimate of the quantity of product in the channel that might be subject to various rebate, chargeback and product return exposures. This is done for
each product line by applying a rate of historical activity for rebates, chargebacks and product returns, adjusted for relevant quantitative and qualitative factors discussed above, to the potential exposed product estimated to be in the
distribution channel. Internal forecasts that are utilized to calculate the estimated number of months in the channel are regularly adjusted based on input from members of the Companys sales, marketing and operations groups. The adjusted
forecasts take into account numerous factors including, but not limited to, new product introductions, direct communication with customers and potential product expiry issues.

The Company periodically offers promotional discounts to the Companys existing customer base. These discounts are calculated as a percentage of the
current published list price and are treated as off-invoice allowances. Accordingly, the discounts are recorded as a reduction of revenue in the period that the program is offered. In addition to promotional discounts, at the time that the Company
implements a price increase, it generally offers its existing customer base an opportunity to purchase a limited quantity of product at the previous list price. Shipments resulting from these programs generally are not in excess of ordinary levels,
therefore, the Company recognizes the related revenue upon shipment and includes the shipments in estimating various product related allowances. In the event the Company determines that these shipments represent purchases of inventory in excess of
ordinary levels for a given wholesaler, the potential impact on product returns exposure would be specifically evaluated and reflected as a reduction in revenue at the time of such shipments.

Allowances for estimated rebates and chargebacks were $9.7 million and $8.0 million as of December 31, 2007 and 2006, respectively. These allowances
reflect an estimate of the Companys liability for items such as rebates due to various governmental organizations under the Medicare/Medicaid regulations, rebates due to managed care organizations under specific contracts and chargebacks due
to various organizations purchasing our products through federal contracts and/or group purchasing agreements. The Company estimates its liability for rebates and chargebacks at each reporting period based on a methodology of applying quantitative
and qualitative assumptions discussed above. Due to the subjectivity of the Companys accrual estimates for rebates and chargebacks, the Company prepares various sensitivity analyses to ensure the Companys final estimate is within a
reasonable range as well as review prior period activity to ensure that the Companys methodology continues to be appropriate.

Allowances for product returns were $43.1 million and $6.1 million as of December 31, 2007 and 2006, respectively. These allowances reflect an estimate of the Companys liability for product that may be returned by the original
purchaser in accordance with the Companys stated return policy. The balance at December 31, 2007 includes the $34.6 million charge recorded in the fourth quarter of 2007 reflecting our estimate of Colazal that may be returned to us under
our return policy as a result of the approval of three generic balsalazide capsule products by the Office of

Generic Drugs on December 28, 2007. The Company estimates its liability for product returns at each reporting period based on historical return rates,
estimated inventory in the channel and the other factors discussed above. Due to the subjectivity of the Companys accrual estimates for product returns, the Company prepares various sensitivity analyses to ensure the Companys final
estimate is within a reasonable range and also reviews prior period activity to ensure that the Companys methodology is still reasonable.

The Companys provision for revenue-reducing items such as rebates, chargebacks, and product returns as a percentage of gross product revenue in the twelve-month periods ended December 31, 2007 and 2006 was 9.7% and 8.8% for
rebates, chargebacks and discounts and was 14.5% and 3.4% for product returns, respectively.

Colazal, the Companys
balsalazide disodium capsule, has historically accounted for a majority of the Companys revenue. On December 28, 2007, the Office of Generic Drugs, or OGD, approved three generic balsalazide capsule products. As a result of these generic
approvals, the Company expects the future sales of Colazal to be significantly less than historical sales of Colazal. In the fourth quarter of 2007, the Company recorded a $34.6 million reserve which is an estimate of the Companys liability
for Colazal that may be returned by the original purchaser in accordance with the Companys stated return policy as a result of these generic approvals. This estimate is based on an estimate of Colazal inventory in the channel and related
expiration dates of this inventory, estimated erosion of Colazal demand based on the generic approvals and the resulting estimated pull-through of Colazal, and other factors. Due to the subjectivity of this estimate, the Company prepares various
sensitivity analyses to ensure the Companys final estimate is within a reasonable range.

Research and Development

In accordance with its policy, the Company expenses research and development costs, both internal and externally contracted, as incurred. Due to increased
development activity levels and the way in which many of the Companys long-term development contracts are structured, the Company conducted a review of its process of estimating research and development expenses during the first quarter of
2006. Based on that review, the Company refined its process of estimating certain externally contracted development activities to more closely align the related expense with the level of progress achieved and services received during the period. In
accordance with Statement of Financial Accounting Standard No. 154, Accounting Changes and Error Corrections, the refined estimation process was implemented in the first quarter of 2006. As of December 31, 2006, the prepaid
amount related to on-going research and development activities was $2.1 million. This prepaid amount, which was charged to expense in 2007 as the related research and development activities were performed under the contracts, resulted in a reduction
of research and development expense for the year ended December 31, 2006 and a corresponding increase in income from operations of $2.1 million, and net income of $2.0 million, or $0.04 per diluted share. At December 31, 2007, the net
asset related to on-going research and development activities to be charged to expense in future periods was $8.9 million. The refined estimation process will continue to be applied on the same basis in future periods.

Cash and Cash Equivalents

The Company considers all
highly liquid investments with maturities from date of purchase of three months or less to be cash equivalents. The Company maintains its cash and cash equivalents in several different financial instruments with various banks and brokerage houses.
This diversification of risk is consistent with Company policy to maintain liquidity and ensure the safety of principal. At December 31, 2007, cash and cash equivalents consisted primarily of demand deposits, overnight investments in
Eurodollars, and money market funds at reputable financial institutions.

Accounts Receivable

The Company extends credit on an uncollateralized basis primarily to wholesale drug distributors and retail pharmacy chains throughout the United States.
The Company is required to estimate the level of accounts receivable

which ultimately will be uncollectible. The Company calculates this estimate based on a review of specific customer balances, industry experience and the
current economic environment. Currently, the Company reserves for specific accounts plus a percentage of the Companys outstanding trade accounts receivable balance as an allowance for uncollectible accounts. Our allowance for uncollectible
accounts at December 31, 2007 and 2006 was $3.1 million and $2.7 million, respectively.

Fair Value of Financial Instruments

The carrying amounts of the Companys financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable, accrued
liabilities, capital lease obligations and the Companys credit facility, approximated their fair values as of December 31, 2007 and 2006 due to the short-term nature of these financial instruments.

Property and Equipment

Property and equipment are
stated at cost and depreciated over the estimated useful lives of the assets, generally three to five years, using the straight-line method.

Inventories

Raw materials, work-in-process and finished goods inventories are stated at the lower of cost (which
approximates actual cost on a first-in, first-out cost method) or market value. In evaluating whether inventory is stated at the lower of cost or market, management considers such factors as the amount of inventory on hand and in the distribution
channel, estimated time required to sell such inventory, remaining shelf life, and current and expected market conditions, including levels of competition, including generic competition. Inventory at December 31, 2007 consisted of $7.5 million
of raw materials, $3.6 million of work-in-process, and $7.4 million of finished goods. Inventory at December 31, 2006 consisted of $14.4 million of raw materials, $2.5 million of work-in-process and $8.2 million of finished goods. As of
December 31, 2007, inventory reserves totaling $0.8 million, compared to $0.7 million as of December 31, 2006, have been recorded to reduce inventories to their net realizable value.

Intangible Assets and Goodwill

The Companys
intangible assets consist of license agreements, product rights and other identifiable intangible assets, which result from product and business acquisitions. Goodwill represents the excess purchase price over the fair value of assets acquired and
liabilities assumed in a business combination.

When the Company makes product acquisitions that include license agreements, product rights
and other identifiable intangible assets, it records the purchase price of such intangibles, along with the value of the product related liabilities that it assumes, as intangible assets. The Company allocates the aggregate purchase price to the
fair value of the various tangible and intangible assets in order to determine the appropriate carrying value of the acquired assets and then amortizes the cost of the intangible assets as an expense in its consolidated statement of operations over
the estimated economic useful life of the related assets. In accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the Company assesses the impairment of
identifiable intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company believes that the following factors could trigger an impairment review: significant underperformance
relative to expected historical or projected future operating results; significant changes in the manner of the Companys use of the acquired assets or the strategy for the Companys overall business; and significant negative industry or
economic trends.

In assessing the recoverability of its intangible assets, the Company must make assumptions regarding estimated future
cash flows and other factors. If the estimated undiscounted future cash flows do not exceed the carrying value of

the intangible assets, the Company must determine the fair value of the intangible assets. If the fair value of the intangible assets is less than the
carrying value, the Company will recognize an impairment loss in an amount equal to the difference. The Company reviews goodwill for impairment on an annual basis, and goodwill and other intangible assets for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable.

The Company assesses impairment of goodwill on an
annual basis in accordance with Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets.

The following table reflects the components of all specifically identifiable intangible assets as of December 31, 2007 (in thousands):



|                               |  |             |         |                         |   |                   |  |             |         |  |

The following table reflects the components of all specifically identifiable intangible assets as
of December 31, 2006 (in thousands):



|                               |  |             |        |                         |   |                   |  |             |        |  |

Amortization expense is calculated on a straight-line basis over the estimated useful life of the
asset. Amortization expense for the years ended December 31, 2007, 2006 and 2005 was $8.6 million, $4.9 million and $2.3 million, respectively. Estimated amortization expense related to intangible assets existing as of December 31, 2007 is
$9.1 million annually for each of the succeeding five years.

In November 2003, the Company acquired from aaiPharma LLC for $2.0 million
the exclusive right to sell 25, 75 and 100 milligram dosage strengths of azathioprine tablets in North America under the name Azasan. The purchase price was fully allocated to product rights and related intangibles and is being amortized over a
period of ten years. Although Azasan does not have any patent protection, the Company believes ten years is an appropriate amortization period based on established product sales history and managements experience. At December 31, 2007 and
2006, accumulated amortization for the Azasan intangible was $0.8 million and $0.6 million, respectively.

In June 2004, the Company
acquired the exclusive U.S. rights to Anusol-HC 2.5% (hydrocortisone Cream USP), Anusol-HC 25 mg Suppository (Hydrocortisone Acetate), Proctocort Cream (Hydrocortisone Cream USP) 1% and Proctocort Suppositories (Hydrocortisone Acetate Rectal
Suppositories, 30 mg) from King Pharmaceuticals, Inc. for $13.0 million. The purchase price was fully allocated to product rights and related intangibles and is being amortized over a period of ten years. Although Anusol-HC and Proctocort do not
have any patent protection, the Company believes ten years is an appropriate amortization period based on established product sales history and managements experience. At December 31, 2007 and 2006, accumulated amortization for the King
product intangibles was $4.6 million and $3.3 million, respectively.

In September 2005, the Company acquired InKine Pharmaceutical
Company, Inc. for $210.0 million. The Company allocated $74.0 million of the purchase price to in-process research and development, $9.3 million to net assets acquired and $37.0 million to specifically identifiable product rights and related
intangibles with an ongoing economic benefit to the Company. The Company allocated the remaining $89.7 million to goodwill, which is not being amortized. The decrease in goodwill over the twelve-month period ended December 31, 2007 was a result
of the use of net operating income tax loss carryforwards generated by InKine prior to its acquisition by the Company in 2005. The

InKine product rights and related intangibles are being amortized over an average period of 14 years, which the Company believes is an appropriate
amortization period due to the products patent protection and the estimated economic lives of the product rights and related intangibles. At December 31, 2007 and 2006, accumulated amortization for the InKine intangibles was $6.8 million
and $3.8 million, respectively.

In December 2005, the Company entered into a License and Supply Agreement with Norgine B.V., granting
Salix the exclusive right to sell a patented-protected, liquid PEG bowel cleansing product, NRL 944, in the United States. Upon execution of the Agreement, the Company made a $2.0 million payment to Norgine. In August 2006, the Company received Food
and Drug Administration marketing approval for NRL 944 under the branded name of MoviPrep. In January 2007 the United States Patent Office issued a patent providing coverage to September 1, 2024. In August 2006, pursuant to the terms of the
Agreement, Salix made a $15.0 million payment to Norgine. The Company is amortizing the milestone payment over a period of 17.3 years, which the Company believes is an appropriate amortization period due to the products patent protection and
the estimated economic life of the related intangible. At December 31, 2007 and 2006, accumulated amortization for the MoviPrep intangible was $1.2 and $0.4 million, respectively.

In February 2007, the Company entered into a Master Purchase and Sale and License Agreement with Merck & Co. Inc., to purchase the U.S
prescription pharmaceutical product rights to Pepcid Oral Suspension and Diuril Oral Suspension from Merck. The Company paid Merck $55.0 million at the closing of this transaction. The purchase price was fully allocated to product rights and related
intangibles, and is being amortized over a period of 15 years. Although Pepcid and Diuril do not have patent protection, the Company believed 15 years is an appropriate amortization period based on established product history and management
experience. At December 31, 2007, accumulated amortization for the Merck products was $3.2 million.

Asset Impairment

The Company reviews the value of its long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable
to determine if an impairment has occurred. If this review indicates that the assets will not be recoverable, based on an analysis of undiscounted cash flows over the remaining amortization period, the Company will reduce the carrying value of its
long-lived assets accordingly, in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets.

The approval of three generic balsalazide capsule products on December 28, 2007 was a change in circumstance that caused us to review the carrying
amount of our long-lived assets. Based on this review there was no impairment to our long-lived assets and no reduction to their carrying value is required.

Shipping and Handling Costs

The Company does not charge its customers for freight costs. The amounts of such costs are
included in selling, general and administrative expenses and are not material.

Advertising Costs

The Company charges advertising costs to expense as incurred. Advertising expenses were approximately $5.7 million, $2.3 million and $3.2 million for the
years ended December 31, 2007, 2006 and 2005, respectively.

Segment Reporting

The Company operates in a single industry and segment acquiring, developing and commercializing prescription drugs used in the treatment of a variety of
gastrointestinal diseases, which are those affecting the digestive tract. Accordingly, the Companys business is classified as a single reportable segment.

Colazal net product revenues for 2007 include a $34.6 million reduction representing the
Companys estimate of Colazal previously sold to wholesalers that may be returned to the Company under its return policy as a result of the approval of three generic balsalazide capsule products on December 28, 2007.

Comprehensive Income (Loss)

The Company
adopted SFAS No. 130, Reporting Comprehensive Income effective January 1, 1998. SFAS 130 requires that the Company display an amount representing comprehensive income (loss) for the year in a financial statement, which is
displayed with the same prominence as other financial statements. The Company elected to present this information in the Consolidated Statements of Stockholders Equity. Other comprehensive income (loss) consists of foreign currency translation
gains and losses, as well as any unrealized gains and losses on investments. For the periods presented, comprehensive income (loss) approximated reported net income (loss).

Stock-Based Compensation

At December 31, 2007, the Company had one active share-based
compensation plan, the 2005 Stock Plan, allowing for the issuance of stock options and restricted shares. Awards granted from this plan are granted at the fair market value on the date of grant, and vest over periods ranging from one to four years.

On December 30, 2005, the Board of Directors approved the acceleration of the vesting of all outstanding unvested stock options. The
acceleration was effective for all such options outstanding on December 30, 2005, all of which were granted by the Company when the accounting rules permitted use of the intrinsic-value method of accounting for stock options. All of the other
terms and conditions applicable to such outstanding stock option grants still apply. Under APB No. 25, the acceleration resulted in recognition of estimated share-based compensation expense of $0.5 million based on the forfeiture assumptions,
which may change in future periods. The Board of Directors took the action with the belief that is was in the best interest of the stockholders, as it will reduce the Companys stock compensation expense in future periods regarding existing
options in light of new accounting regulations effective beginning in fiscal year 2006. As a result of the accelerations, options to purchase 3.6 million shares of the Companys common stock became immediately exerciseable.

Prior to January 1, 2006, the Company accounted for stock-based awards to employees under the intrinsic value method in accordance with Accounting
Principles Board Opinion, or APB, No. 25, Accounting for Stock Issued to Employees and adopted the disclosure-only alternative of SFAS No. 123, Accounting for Stock-Based Compensation.

In December 2004, the Financial Accounting Standards Board issued SFAS No. 123R, Share-Based Payment, which requires companies to
expense the fair value of employee stock options and other forms of stock-based compensation. This requirement represents a significant change because share-based stock option awards, a historically predominant form of stock compensation for the
Company, were not recognized as compensation expense under APB 25. SFAS No. 123R requires the cost of the award, as determined on the grant date at fair value, to be recognized over the period during which an employee is required to provide
service in exchange for the award, usually the vesting period. The grant-date fair value of the award is estimated using an option-pricing model.

The Company adopted SFAS No. 123R effective January 1, 2006 using the modified-prospective
transition method. The modified-prospective transition method of SFAS No. 123R requires the presentation of pro forma information, for periods presented prior to the adoption of SFAS No. 123R, regarding net income and net income per share
as if the Company had accounted for its stock plans under the fair value method of SFAS No. 123R. For pro forma purposes, fair value of stock option awards was estimated using the Black-Scholes option valuation model. The fair value of all of
the Companys share-based awards was estimated assuming no expected dividends and estimates of expected life, forfeitures, volatility and risk-free interest rate at the time of grant.

Income Taxes

The Company provides for income taxes
under the liability method in accordance with SFAS No. 109, Accounting for Income Taxes. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between
the tax basis of assets or liabilities and their carrying amounts in the consolidated financial statements. The Company provides a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before
the Company is able to realize their benefit or if future deductibility is uncertain.

In June 2006, the FASB issued FASB Interpretation
No. 48 Accounting for Uncertainty in Income Taxes (FIN 48), which is an interpretation of SFAS 109 Accounting for Income Taxes. This interpretation prescribes a recognition threshold and measurement attribute
for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognizing, classification, interest and penalties, accounting in interim periods, disclosure
and transition.

On January 1, 2007, the Company adopted the provisions of FIN 48. As a result of applying the provisions of FIN 48,
the Company recognized an increase of $2.4 million in the liability for unrecognized tax benefits and a reduction in the valuation allowance as of January 1, 2007 for the same amount. The unrecognized tax benefits as December 31, 2007
relate to federal tax credit carryforwards. The Company does not expect the unrecognized tax benefits to change significantly over the next 12 months.

The Company continues to fully recognize its tax benefits which are offset by a valuation allowance to the extent that it is more likely than not that the deferred tax assets will not be realized. The Company does not
expect any significant changes in its unrecognized tax benefits for the next twelve months.

The Company files a consolidated U.S. federal
income tax return and consolidated and separate company income tax returns in many U.S. state jurisdictions. Generally, the Company is no longer subject to federal and state income tax examinations by U.S. tax authorities for years prior to 1993.
The Internal Revenue Service has commenced an examination of the Companys U.S. income tax return for 2005. The Company anticipates that any adjustments as a result of this examination would not be material to its financial position.

The Company recognizes any interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.
During the twelve-month period ended December 31, 2007 there was no such interest or penalties.

Net Income (Loss) Per Share

The Company computes net income (loss) per share in accordance with SFAS No. 128, Earnings Per Share (SFAS 128). Under the
provisions of SFAS 128, basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) by the
weighted average number of common shares and dilutive common share equivalents then outstanding. Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options and the impact of vested restricted stock
grants.

Recently Issued Accounting Pronouncements

In December 2007, the FASB issued SFAS No. 141
(revised 2007) Business Combinations (SFAS 141R). SFAS 141R is effective for fiscal years beginning on or after December 15, 2008, which means that we will adopt SFAS 141R in our fiscal year 2009. SFAS 141R replaces SFAS 141
Business Combinations and requires that the acquisition method of accounting (which SFAS 141 called the purchase method) be used for all business combinations, as well as for an acquirer to be identified for each business combination.
SFAS 141R establishes principles and requirements for how the acquirer: (i) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree;
(ii) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and (iii) determines what information to disclose to enable users of financial statements to evaluate the nature and
financial affects of the business combination. The Company is currently evaluating the impact of adoption of SFAS 141R on the Companys consolidated financial position, results of operations and cash flows.

In December 2007, the FASB issued SFAS No. 160 Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB
No. 51 (SFAS 160). SFAS 160 is effective for fiscal years beginning on or after December 15, 2008, which means that we will adopt SFAS 160 in our fiscal year 2009. This statement amends ARB 51 to establish accounting and reporting
standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 changes accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a
component of equity in the Consolidated Financial Statements. SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. All other requirements of SFAS 160 shall be applied prospectively.
The Company does not believe the adoption of SFAS 160 will have a material impact on the Companys consolidated financial position, results of operations and cash flows.

In February 2007, the FASB issued SFAS No. 159 The Fair Value Option for Financial Assets and Financial Liabilities
(SFAS 159). SFAS 159 permits entities to choose, at specified election dates, to measure eligible items at fair value (the Fair Value Option). Unrealized gains and losses on items for which the Fair Value Option has been elected are
reported in earnings. The Fair Value Option is applied instrument by instrument (with certain exceptions), is irrevocable (unless a new election date occurs) and is applied only to an entire instrument. The effect of the first remeasurement to fair
value is reported as a cumulative-effect adjustment to the opening balance of retained earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company does not expect the adoption of SFAS 159 to have a material
impact on the Companys consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS
No. 157 Fair Value Measurements (SFAS 157), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and



F-17

expands disclosures about fair value measurements. This Statement applies to other accounting pronouncements that require or permit fair value measurements,
the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim
periods within those fiscal years. In February 2008, the FASB released FSP No. FAS 157-2. FSP No. FAS 157-2 defers the effective date of FASB 157 for one year for nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at
fair value in the financial statements on a nonrecurring basis. It does not defer recognition and disclosure requirements for financial assets and financial liabilities, or for nonfinancial assets and nonfinancial liabilities that are remeasured at
least annually. The Company does not expect the adoption of SFAS 157 to have a material impact on the Companys consolidated financial position, results of operations or cash flows.

(5) CREDIT FACILITY

In February 2007, the Company entered into a $100.0 million revolving credit facility that matures in February 2012. At December 31, 2007, $15.0 million was outstanding under the credit facility. Virtually
all assets of the Company and its subsidiaries secure the Companys obligations under the credit facility. Borrowings under the credit facility may be used for working capital, capital expenditures, acquisitions and other general corporate
purposes.

Notes To Consolidated Financial Statements  Continued



The credit facility bears interest at a rate per annum equal to, at the Companys option, either
(a) a base rate equal to the higher of (i) the Federal Funds Rate plus 1/2 of 1% and (ii) the Bank of America prime rate, or (b) a Eurodollar rate (based on LIBOR), plus, in each case, a percentage rate that fluctuates, based on
the ratio of the Companys funded debt to EBITDA (income before income taxes plus interest expense and depreciation and amortization), from 0.00% to 0.75% for base rate borrowings and 1.00% to 1.75% for Eurodollar rate borrowings.

The credit facility contains various representations, warranties and affirmative, negative and financial covenants customary for financings of this
type. The financial covenants include a leverage test and a fixed charge test. The Company was in compliance with these covenants at December 31, 2007. Based on current forecasts, the Company could fall out of compliance with these financial
covenants during 2008, unless the Company obtains a waiver or amends the facility.

(6) STOCKHOLDERS EQUITY

Preferred Stock

A total of 5,000,000 shares of
preferred stock are authorized and issuable. No shares of preferred stock were issued or outstanding as of December 31, 2007.

Common Stock

As of December 31, 2007 the Company was authorized to issue up to 80,000,000 shares of $0.001 par value common stock. As of
December 31, 2007 and 2006, there were 47,708,985 and 47,033,717 shares of common stock issued and outstanding, respectively.

Stockholder Rights
Plan

On January 9, 2003, the Companys Board of Directors adopted an updated stockholder rights plan. Consequently, the Board
authorized the redemption, effective on January 20, 2003, of rights under its existing stockholder rights plan for $0.0001 per right. Pursuant to the updated plan, stock purchase rights were distributed to stockholders at the rate of one right
with respect to each share of common stock held of record as of January 20, 2003. The rights plan is designed to enhance the Boards ability to prevent an acquirer from depriving stockholders of the long-term value of their investment and
to protect stockholders against attempts to acquire the Company by means of unfair or abusive takeover tactics. The rights become exercisable based upon certain limited conditions related to acquisitions of stock, tender offers and business
combinations involving the Company.

Stock Plans

The Companys 1994 Stock Plan (the 1994 Plan) was adopted by the Board of Directors in March 1994 and approved by the stockholders in March 1995. The Companys 1996 Stock Plan (the 1996
Plan) was adopted by the Board of Directors and approved by the Companys stockholders in February 1996. The Companys 2005 Stock Plan (the 2005 Plan) was adopted by the Board of Directors in April 2005 and approved by
the stockholders in June 2005. The stock granted under the 1994 Plan, the 1996 Plan and the 2005 Plan may be either stock options or restricted shares. Stock options expire no later than ten years from the date of grant.

Option prices shall be at least 100% of the fair market value on the date of grant for incentive stock options, and no less than 85% of the fair market
value for nonqualified stock options. If, at the time the Company grants an option, the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the exercise
price for an incentive stock option shall be at least 110% of the fair market value and the option shall not be exercisable more than five years after the date of grant. The options generally become exercisable in increments of 1/48th per month
over a period of 48 months from the date of grant. Options may be granted with different vesting terms as determined by the board of directors. Since inception of the Companys 1994 Plan, 1996 Plan and 2005 Plan the Companys stock option
grants were all at fair market value. Starting in 2006, the Company began issuing restricted shares to employees, executives and directors of the Company.

Stock-Based Compensation

At December 31, 2007, the Company had one active share-based compensation plan, the 2005 Stock Plan, allowing for the issuance of stock options and restricted shares. Awards granted from this plan are granted at
the fair market value on the date of grant and vest over periods ranging from one to four years.

On December 30, 2005, the Board of
Directors approved the acceleration of the vesting of all outstanding unvested stock options. The acceleration was effective for all such options outstanding on December 30, 2005, all of which were granted by the Company when the accounting
rules permitted use of the intrinsic-value method of accounting for stock options. All of the other terms and conditions applicable to such outstanding stock option grants still apply. Under APB No. 25, the acceleration resulted in recognition
of estimated share-based compensation expense of $0.5 million based on forfeiture assumptions, which may change in future periods. The Board of Directors took the action with the belief that it is in the best interests of stockholders, as it will
reduce the Companys stock compensation expense in future periods regarding existing stock options in light of new accounting regulations effective beginning in fiscal year 2006. As a result of the acceleration, options to purchase
3.6 million shares of the Companys common stock became immediately exercisable. If these options had not been accelerated, the Company estimates that additional share-based compensation expense totaling $16.8 million would have been
recognized in 2006, and the estimated balance of $29.8 million would have been recognized over the remaining vesting period of approximately 3.0 years.

Prior to January 1, 2006, the Company accounted for stock-based awards to employees under the intrinsic value method in accordance with Accounting Principles Board Opinion, or APB, No. 25, Accounting
for Stock Issued to Employees and adopted the disclosure-only alternative of SFAS No. 123, Accounting for Stock-Based Compensation.

In December 2004, the Financial Accounting Standards Board issued SFAS No. 123R, Share-Based Payment, which requires companies to expense the fair value of employee stock options and other forms of
stock-based compensation. This requirement represents a significant change because share-based stock option awards, a historically predominate form of stock compensation for the Company, were not recognized as compensation expense under APB 25. SFAS
No. 123R requires the cost of the award, as determined on the date of grant at fair value, to be recognized over the period during which an employee is required to provide service in exchange for the award, usually the vesting period. The
grant-date fair value of the award is estimated using an option-pricing model.

The Company adopted SFAS No. 123R effective
January 1, 2006 using the modified-prospective transition method. The modified-prospective transition method of SFAS No. 123R requires the presentation of pro forma information, for periods presented prior to the adoption of SFAS
No. 123R, regarding net income and net income per share as if the Company had accounted for its stock plans under the fair value method of SFAS No. 123R. For pro forma purposes, fair value of stock option awards was estimated using the
Black-Scholes option valuation model. The fair value of all of the Companys share-based awards was estimated assuming no expected dividends and estimates of expected life, volatility and risk-free interest rate at the time of grant.

The fair value of the Companys stock option awards granted in 2005 was estimated using the following weighted-average assumptions:



|                        |  |      |  
|----------------------- |  | ---- | -
|                        |  | 2005 |  
|Expected life (years)   |  | 5    |  
|Expected volatility     |  | 0.96 |  
|Risk-free interest rate |  | 3.96 | %

Starting in 2006, the Company began issuing restricted shares to employees, executives and directors
of the Company. The restrictions on the restricted stock lapse according to one of two schedules. For employees and executives of the Company, restrictions lapse 25% annually over four years. For board members of the company, restrictions lapse
100% after one year. The fair value of the restricted stock was estimated using an assumed forfeiture rate of 8.1% and is being expensed on a straight-line basis over the period during which the restrictions lapse. For the year ended
December 31, 2007, the Company recognized $3.7 million in share based compensation expense related to the restricted shares. As of December 31, 2007, the total amount of unrecognized compensation cost related to nonvested restricted stock
awards, to be recognized as expense subsequent to December 31, 2007, was approximately $12.2 million, and the related weighted-average period over which it is expected to be recognized is approximately 3.04 years.

compensation expense related to stock options for the year ended December 31, 2006, nor any income tax benefit. The total intrinsic value of options
exercised for the year ended December 31, 2007 was $3.0 million. As of December 31, 2007, there was no unrecognized compensation cost due to the fact that all stock options were fully vested as noted above. For the year ended
December 31, 2007, the Company received $2.1 million in cash from stock option exercises.

(7) INCOME TAXES

As of December 31, 2007, the Company had U.S. federal net operating loss carryforwards of $37.0 million. Of this amount, approximately $20.4 million
is limited by section 382 of the Internal Revenue Code. The Companys remaining net operating loss carryforwards of approximately $16.6 million relates to excess stock option benefit which, if and when realized, will credit additional paid-in
capital. The Company also has gross North Carolina net operating loss carryforwards in the amount of $27.0 million.

The provision for
income taxes in the accompanying consolidated statements of operations for the years ended December 31, 2007, 2006 and 2005 consisted of the following (in thousands):

The Company has provided a valuation allowance for the gross deferred tax asset due to the
uncertainty regarding the Companys ability to realize the entire asset. The valuation allowance has decreased by approximately $8.5 million and $4.8 million during the years ended December 31, 2007 and 2006, respectively.

The deferred tax assets include deferred tax assets and liabilities acquired from InKine which were
fully reserved in the amount of $15.6 million. In the current year, $3.3 million of these deferred tax assets were realized, resulting in a reduction to goodwill.

Utilization of the federal net operating loss carryforwards may be subject to a substantial annual limitation due to the change in ownership provisions of the Internal Revenue Code of 1986. If this limitation applies,
the ultimate ability for the Company to use existing net operating loss carryovers and tax credit carryovers to offset future income may be limited. The Companys net operating loss carryforwards begin to expire at the end of the taxable year
ending December 31, 2020.

A reconciliation of the statutory income tax rate to the effective income tax rate is as follows:

In June 2006, FASB issued FASB Interpretation No. 48 Accounting for Uncertainty in
Income Taxes (FIN 48), which is an interpretation of SFAS 109 Accounting for Income Taxes. This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and
measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

On January 1, 2007, the Company adopted the provisions of FIN 48. As a result of applying the provisions of FIN 48, the Company recorded an increase
of $2.4 million in its unrecognized tax benefits. The unrecognized tax benefits as of December 31, 2007 relate to federal tax credit carryforwards. The Company does not expect our unrecognized tax benefits to change significantly over the next
12 months.

The following table summarizes the activity related to our unrecognized tax benefits (in thousands):



|                                                |  |   |

|                                                |  |   |      

If these unrecognized tax benefits of $2.4 million at December 31, 2007 were recognized, they
would have decreased the Companys annual effective tax rate. No expense has been recorded for interest and penalties related to these tax positions.

The 1993 through 2007 tax years remain subject to examination by federal and state taxing authorities. The 2005 tax year is currently under audit by the Internal Revenue Service.
