PART I

Item 1. Business

THE COMPANY

     References in this Report to “Connetics,” “the Company,” “we,” “our” and “us” refer to Connetics Corporation, a Delaware corporation, and its consolidated subsidiaries. Unless the context specifically requires otherwise, “we” includes Connetics Australia Pty Ltd. Our principal executive offices are located at 3290 West Bayshore Road, Palo Alto, California 94303. Our telephone number is (650) 843-2800. Connetics®, Luxíq®, and OLUX® are registered trademarks, and Extina™, Actiza™, Liquipatch™, Solux™ and the seven interlocking “C’s” design are trademarks, of Connetics. All other trademarks or service marks appearing in this Report are the property of their respective companies. We disclaim any proprietary interest in the marks and names of others.

     Connetics is a specialty pharmaceutical company focusing exclusively on the treatment of dermatological conditions. We currently market two pharmaceutical products, OLUX® Foam (clobetasol propionate), 0.05%, and Luxíq® Foam (betamethasone valerate), 0.12%. Our commercial business is focused on the dermatology marketplace, which is characterized by a large patient population that is served by a relatively small number of treating physicians. Our two dermatology products have clinically proven therapeutic advantages for the treatment of dermatoses in a novel formulation, and we are providing quality customer service to dermatologists through our experienced sales and marketing professionals.

Table of Contents

     We established the Connetics Center for Skin Biology with a goal of connecting the scientific understanding of skin disease with better treatment options. The Center was created to bring together dermatologists and pharmacologists from across the country to interact with our researchers to explore how topical drugs interact with and penetrate the skin. The purpose of the Center is to learn how to optimize drug penetration, distribution, and efficiency at the targeted treatment site on the skin, and to assess novel formulations and new delivery technologies. The Center will assist in the continued development of innovative topical dermatology products through rigorous scientific evaluation of products and product candidates. We believe this novel approach to drug development will enable us to bring even more effective and novel treatments to our product platform and the dermatology market.

     Our products, OLUX and Luxíq, compete in the topical steroid market. According to NDC Health, in 2002, the value of the retail topical steroid market for mid-potency and high and super-high potency steroids was $831 million. Luxíq competes in the mid-potency steroid market and OLUX competes in the high- and super-high potency steroid market.

     Dermatological diseases often persist for an extended period of time and are treated with a variety of clinically proven drugs that are delivered in a variety of formulations, including solutions, creams, gels and ointments. These existing delivery systems often inadequately address a patient’s needs for efficacy and cosmetic elegance, and the failure to address those needs may decrease patient compliance. We believe that the proprietary foam delivery system unique to OLUX and Luxíq has significant advantages over conventional therapies for dermatoses. The foam formulation liquefies when applied to the skin, and enables the active therapeutic agent to penetrate rapidly. When the foam is applied, it dries quickly, and does not leave any residue, stains or odor. We believe that the combination of the increased efficacy and the cosmetic elegance of the foam may actually improve patient compliance and satisfaction. In market research sponsored by Connetics, 80% of patients said that they preferred the foam to other topical delivery vehicles.

     We acquired our wholly-owned subsidiary, Connetics Australia Pty Ltd. (formerly Soltec Research Pty Ltd.) in 2001. The acquisition, for which we paid approximately U.S. $16.9 million, was intended to provide us with powerful product innovation and development capabilities and to fuel an extensive new product pipeline as well as contributing revenue and profits to our financial results. We have leveraged our broad range of drug delivery technologies by entering into license agreements with many well-known dermatology companies around the world. Those license agreements for marketed products bear royalties payable to us. In connection with the acquisition, we gained worldwide rights to a number of unique topical delivery systems, including several distinctive aerosol foams including water-, ethanol- and petrolatum- based foams. Consolidating the rights to these technologies enables us to populate our own product development portfolio, as well as pursue business development agreements with other pharmaceutical companies for over-the-counter and foreign markets.

OUR STRATEGY

     Our principal business objective is to be a leading specialty pharmaceutical company focused on providing innovative treatments in the field of dermatologic disease. To achieve this objective, we intend to continue to pursue our commercial strategy of maximizing product sales by leveraging novel delivery technologies, accelerating the processes of getting products to market, and targeting specific market opportunities with unmet needs. We have described our development paradigm as a “4:2:1 model.” We strive in any given year to have four product candidates in product formulation, two product candidates in late-stage clinical trials, and one product or new indication launched commercially. We fuel our product pipeline by a combination of internally developing product candidates and in-licensing novel products that fit with our broader strategy. Key elements of our business and commercialization strategy include the following:

•

Maximizing Near-Term Commercial Opportunities for OLUX and Luxíq. We have a focused sales force dedicated to establishing OLUX and Luxíq as the standard of care. Our commercial strategy permits us to effectively reach the majority of the treating dermatologists. In 2002, we introduced sample-size versions of both our products. In December 2002, we received approval from the FDA to market OLUX for the treatment of non-scalp psoriasis, specifically the short-term topical treatment of mild to moderate plaque-type psoriasis of non-scalp regions excluding the face and intertriginous areas.

Table of Contents

	•		Advancing the Development of Novel Dermatology Drugs. We plan to continue to leverage our investment in Connetics Australia and the Center for Skin Biology to enhance our ability to develop novel products and drug delivery technologies for the dermatology market.
	•		Broadening Our Product Portfolio Through Development, License or Acquisition. We believe that we can leverage our dermatology-dedicated sales force by marketing additional products to the dermatology market. In 2002, we acquired the rights to Velac®, a first-in-class combination of 1% clindamycin and 0.025% tretinoin for the treatment of acne. Also in 2002, we in-licensed the rights to access the clinical, regulatory and manufacturing records of a currently approved and marketed dermatological product. Connetics intends to reformulate and market the product using its proprietary foam delivery vehicle. Details regarding the product and the target market were not disclosed. We are evaluating the licensing or acquisition of additional product candidates. We may also acquire additional technologies or businesses that we believe will enhance our research and development capabilities.
	•		Selective Collaborations. As we expand certain aspects of our development pipeline and delivery technologies, we intend to partner with pharmaceutical or biotech companies to gain access to additional marketing expertise, such as over-the-counter or non-U.S. markets. Our approach to partnership will be on a selective basis, seeking to maintain the highest possible value of our product candidates.

OUR PRODUCTS

OLUX Foam

     OLUX is a foam formulation of clobetasol propionate, one of the most widely prescribed super high-potency topical steroids. OLUX has been proven to deliver rapid and effective results for scalp and non-scalp psoriasis. In fact, according to Physician Global Assessments, significantly more patients were completely clear or almost clear after two weeks of treatment.

     We began selling OLUX in November 2000 for the short-term, topical treatment of inflammatory and pruritic manifestations of moderate to severe corticosteroid-responsive scalp dermatoses. In moderate to severe scalp psoriasis significantly more patients (74%) treated with OLUX achieved 90 - 100% clearance (Investigators’ Global Assessment) within two weeks as compared with patients treated with placebo (10%; p<0.001). In a more rigorous assessment of efficacy from the Phase III clinical trial, treatment success was achieved in 63% of OLUX -treated patients compared to 57% of patients treated with clobetasol solution.

     In December 2002, the FDA approved our supplemental New Drug Application, or sNDA, to market OLUX for a non-scalp indication. The sNDA was based on results from a 279-patient, placebo-controlled, randomized, double-blind, Phase III clinical trial of OLUX for the treatment of mild-to-moderate non-scalp psoriasis. During the study, patients treated with OLUX experienced a statistically significant improvement in clearance of disease (p < 0.0001) over patients in the placebo group after treatment twice a day for 14 days. Patients were evaluated using the Physician’s Static Global Assessment score as the primary endpoint, and patient’s global assessment and erythema, scaling, plaque thickness, and pruritus baselines as secondary endpoints. In non-scalp psoriasis significantly more patients (68%) treated with OLUX achieved a Physician’s Static Global Assessment score of 0 or 1 within two weeks as compared with patients treated with placebo (21%; p<0.001). In a more rigorous assessment of efficacy, treatment success was achieved in 28% of OLUX-treated patients vs. 3% of patients treated with placebo. Treatment success was scored on a severity scale from 0 to 5, and was defined as a Physician’s Static Global Assessment score of 0 or 1, plus a plaque thickness score of 0, an erythema score of 0 or 1, and a scaling score of 0 or 1 at endpoint. There was no statistical difference in the reported adverse events between the OLUX and placebo groups. The most common adverse events reported were application site reactions (burning and dryness).

     A separate study conducted at Stanford University School of Medicine, presented at the Annual Hawaii Dermatology Seminar in January 2002, compared the safety and effectiveness, patient satisfaction, quality of life, and cost-effectiveness of two clobetasol regimens in the treatment of psoriasis. In a single-blind design, 29 patients were randomized to receive either clobetasol foam on the skin and scalp or a combination of clobetasol cream on the skin and lotion on the scalp for 14 days. Severity of disease and quality of life were evaluated using several tools, including the Psoriasis Area Severity Index and the Dermatology Life Quality Index. The trial showed that the

increased improvement in clinical severity, decreased application time, and increased perception of relative efficacy, combined with similar cost of treatment, suggest that OLUX is a better choice than cream and solution for some patients. This study supports our belief that improved patient compliance with the foam will yield better treatment results than the same active ingredient in other formulations.

     Mipharm S.p.A., which holds a license to market OLUX in Italy, filed a Marketing Authorization Application, or MAA, in April 2002 for OLUX with the Medicines Control Agency, or MCA, in the United Kingdom. It is our intention to submit the MAA to all additional concerned member states in the European Union after the MCA grants authorization, using a process called the Mutual Recognition process. We are seeking commercial partners outside the territory licensed to Mipharm.

Luxíq Foam

     Luxíq is a foam formulation of betamethasone valerate, a mid-potency topical steroid prescribed for the treatment of mild-to-moderate steroid-responsive scalp dermatoses such as psoriasis, eczema and seborrheic dermatitis. We began selling Luxíq commercially in the United States in April 1999. In a clinical trial, a majority of patients were judged to be almost clear or completely clear (90-100%) of scalp psoriasis at the end of treatment as judged by Investigator’s Global Assessment of response. Luxíq also significantly reduced scaling, erythema, and plaque thickness, as compared with betamethasone valerate lotion.

PRODUCT CANDIDATES AND CLINICAL TRIALS

     Our product candidates require extensive clinical evaluation and clearance by the FDA before we can sell them commercially. Our 4:2:1 development model anticipates that we will conduct simultaneous studies on several products at a given time. However, we regularly re-evaluate our product development efforts. On the basis of these re-evaluations, we have in the past, and may in the future, abandon development efforts for particular products. In addition, any product or technology under development may not result in the successful introduction of a new product.

     At the end of 2002, we had three product candidates in Phase III clinical trials. We are in Phase III clinical trials with Extina™, a foam formulation of a 2% concentration of the antifungal drug ketoconazole, for the treatment of seborrheic dermatitis. The Extina clinical program consists of a pivotal trial and two small supplemental clinical studies required by the FDA. In the pivotal trial, which completed enrollment in late January 2003, patients were treated for four weeks in a double-blind, placebo- and active-controlled protocol. Subject to a successful outcome, we intend to submit a New Drug Application, or NDA, to the FDA for Extina in mid-2003. We believe Extina will compete primarily in the topical antifungal market, representing approximately $484 million in U.S. prescriptions in 2002. Prescriptions for all antifungals in the U.S. in 2002 were approximately $693 million.

     We are in Phase III clinical trials with Actiza™, a formulation of 1% clindamycin in our proprietary foam delivery system, for the treatment of acne. The Actiza clinical program consists of a pivotal trial, a pilot trial, and two small supplemental clinical studies required by the FDA. In the pivotal trial, patients will be treated for 12 weeks in a double-blind, placebo- and active-controlled protocol. Subject to a successful outcome, we intend to submit an NDA to the FDA for Actiza in late 2003. We believe Actiza will compete primarily in the topical antibiotic market, representing approximately $594 million in U.S. prescriptions in 2002. Prescriptions for the entire U.S. acne market in 2002 were approximately $1.5 billion not including oral antibiotics.

     In December, we initiated the Phase III program for Velac® gel, a first-in-class combination of 1% clindamycin and 0.025% tretinoin for the treatment of acne. The Velac clinical program consists of two pivotal trials, and two small supplemental clinical studies required by the FDA. The two pivotal trials will enroll approximately 2,000 patients. Assuming successful clinical development, we anticipate that we will submit an NDA to the FDA for Velac in 2004 and be able to launch Velac in mid-2005. We believe Velac will compete with topical retinoids as well as topical antibiotics, representing approximately $977 million in U.S. prescriptions in 2002. Prescriptions for the entire U.S. acne market in 2002 were approximately $1.5 billion not including oral antibiotics.

     In February 2003, we began a promotional giveaway to dermatologists of Solux™, a sunscreen formulated in our proprietary foam delivery system. The goal of the program is to introduce the foam delivery vehicle to a broad physician audience.

     In addition to the product candidates described above, we are also developing the foam technology for other disease indications. Our most promising preclinical candidates include a petrolatum-based foam as line extensions for OLUX and Luxíq, and other formulation candidates in early stages of development. We are exploring various product formulations for Liquipatch™ as well.

ROYALTY-BEARING PRODUCTS AND LICENSED TECHNOLOGY

     Foam Technology. In December 2001, we entered into an agreement granting Pharmacia Corporation exclusive global rights, excluding Japan, to our proprietary foam drug delivery technology for use with Pharmacia’s Rogaine® hair loss treatment. The license with Pharmacia will expand the reach of the foam vehicle to the non-prescription (over-the-counter) pharmaceutical market. Under the agreement, Pharmacia paid us an initial licensing fee, and agreed to pay us when it achieves specified milestones, plus a royalty on product sales. We have recognized $1.0 million under the agreement through December 31, 2002. Pharmacia will be responsible for most product development activities and costs.

     Before April 2001, Connetics Australia (under the name Soltec) had entered into a number of other agreements for the foam technology. Connetics Australia licensed the technology to betamethasone valerate foam to Celltech plc in Europe, and Celltech has licensed the worldwide rights to their patent on the steroid foam technology to us through Connetics Australia. We pay Celltech royalties on all sales worldwide of foam formulations containing steroids. Celltech markets their product as Bettamousse® (the product equivalent of Luxíq), and pays us royalties on those sales. We have license agreements with Bayer (in the U.S.) and Pfizer and Mipharm (internationally) for the use of pyrethrin foam for head lice. That product is marketed in the U.S. as RID®, as Banlice® in Australia, and as Milice® in Italy. We receive royalties on sales of those products. In 2002, on a consolidated basis, we received $307,000 in royalties for foam-based technology. We have development agreements with other companies to develop the foam for specific indications.

     We have licensed to Mipharm commercial rights for Italy to OLUX, and we will receive milestone payments and royalties on future product sales. In April 2002, Mipharm began the process to obtain marketing authorization in Europe, by filing a Marketing Authorization Application with the Medicines Control Agency in the United Kingdom. Under the Mutual Recognition process in Europe, after the MCA approves the MAA, we will be able to submit the MAA to all other European Union concerned member states for approval to sell OLUX. We retained marketing and manufacturing rights for the rest of Europe and are seeking commercial partners outside of Mipharm’s territory.

     Aerosol Spray. Connetics Australia has licensed to a major international company the rights to a super-concentrated aerosol spray that is marketed in the U.S. and internationally. We receive royalties on sales of the product. In 2002, on a consolidated basis, we received $2.4 million in royalties in connection with this agreement.

     Liquipatch. We have agreements with several companies to develop Liquipatch™ for various indications. In June 2001, we entered into a global licensing agreement with Novartis Consumer Health SA for the Liquipatch drug-delivery system for use in topical antifungal applications. The agreement followed successful pilot development work and gives Novartis the exclusive, worldwide right to use the Liquipatch technology in the topical antifungal field. In March 2002, Novartis paid $580,000 to exercise its then-existing option to expand the license agreement. Novartis will be responsible for all development costs, and will be obligated to pay license fees, milestone payments and royalties on future product sales. We have development agreements with other companies to develop Liquipatch for specific indications.

     Actimmune®. In 1995, we acquired from Genentech, Inc. the exclusive development and marketing rights to interferon gamma for dermatological and other indications in the U.S., Japan, and Canada. Interferon gamma is one of a family of proteins involved in the regulation of the immune system and has been shown to reduce the frequency and severity of certain infections. In April 2000, we assigned our remaining rights and obligations under the license with Genentech and the corresponding supply agreement to InterMune Pharmaceuticals, Inc. (now InterMune, Inc.), to develop Actimmune for various infections and fungal diseases. In exchange, InterMune paid us approximately $6.1 million, of which $942,000 was paid to us in March 2001 and the balance was paid in 2000. We recorded $172,000 in royalty revenue related to Actimmune sales in 2002. In August 2002, we entered into an

5

Table of Contents

agreement with InterMune to terminate our exclusive option for certain rights in the dermatology field in exchange for a payment of $350,000. We recognized the full amount of this revenue in 2002.

     Ridaura®. In April 2001, we sold all of our rights and interests in Ridaura® (auranofin) to Prometheus Laboratories, Inc. Ridaura is a prescription pharmaceutical product for the treatment of rheumatoid arthritis. The decision to divest the product was consistent with our decision to focus exclusively on dermatology. Under the terms of the agreement with Prometheus, we sold all of our rights, interests and assets for or related to the use, manufacture or sale of Ridaura in the United States and Puerto Rico for $9.0 million in cash plus a royalty on annual sales of Ridaura in excess of $4.0 million per calendar year through March 2006. We received no royalties in 2002. Prometheus agreed to assume, effective as of the closing date of the transaction, our obligations under existing agreements with Pharmascience, Inc. and SmithKline Beecham Corporation (now known as GlaxoSmithKline).

SALES AND MARKETING

     We have an experienced, highly productive sales and marketing organization, which is 100% dedicated to dermatology. As of March 3, 2003, we had 76 employees in our sales and marketing organization, including 60 field sales directors and representatives.

     Our marketing efforts are focused on assessing and meeting the needs of dermatologists, residents, dermatology nurses, and physicians’ assistants. Our sales representatives focus on cultivating relationships of trust and confidence with the physicians they call on. Of the 7,500 U.S. dermatologists our sales force called on in 2002, we focused our efforts on the approximately 5,000 dermatologists who are responsible for approximately 90% of all prescriptions written by dermatologists in the United States. To achieve our marketing objectives, we use a variety of advertising, promotional material (including journal advertising, promotional literature, and rebate coupons), specialty publications, participation in educational conferences, support of continuing medical education activities, and advisory board meetings, as well as product internet sites to convey basic information about our products and our company. Our corporate website at http://www.connetics.com includes fundamental information about the company as well as descriptions of ongoing research, development and clinical work. Our product websites, at http://www.olux.com and http://www.luxiq.com, provide information about the products and their approved indications, as well as copies of the full prescribing information, the patient information booklet, and rebate coupons.

     In addition to traditional marketing approaches and field sales relationships with dermatologists, we sponsor several programs that support the dermatology field. We currently provide funding to sponsor one dermatology resident at the Stanford University Medical School, and a dermatology fellow at the University of California – San Francisco. We are working to provide an innovative surgery-tracking program for dermatology residents. We also provide corporate sponsorship to various dermatology groups, including the National Psoriasis Foundation, the Dermatology Foundation, the Skin Disease Education Foundation, and the Foundation for Research & Education in Dermatology. In 2002, we sponsored 15 children to attend Camp Wonder, a summer camp sponsored by the Childrens’ Skin Disease Foundation for children suffering from serious and fatal skin diseases.

COMPETITION

     The specialty pharmaceutical industry is characterized by intense market competition, extensive product development and substantial technological change. We also face competition from other manufacturers of prescription pharmaceuticals for our dermatology products as well as other products that we may develop and market in the future. Many of our competitors are large, well-established pharmaceutical, chemical, cosmetic or health care companies with considerably greater financial, marketing, sales and technical resources than those available to us. Additionally, many of our present and potential competitors have research and development capabilities that may allow such competitors to develop new or improved products that may compete with our product lines. Our products could be rendered obsolete or made uneconomical by the development of new products to treat the conditions addressed by our products, technological advances affecting the cost of production, or marketing or pricing actions by one or more of our competitors. Each of our products competes for a share of the existing market with numerous products that have become standard treatments recommended or prescribed by dermatologists.

Table of Contents

     OLUX and Luxíq compete with a number of corticosteroid brands in the super-, high- and mid-potency categories for the treatment of inflammatory skin conditions. Competing brands include Halog® and Ultravate®, marketed by Bristol-Myers Squibb Company; Elocon® and Diprolene®, marketed by Schering-Plough Corporation; Locoid®, marketed by Ferndale Labs; Temovate® and Cutivate®, which are marketed by GlaxoSmithKline as of late 2002; DermaSmoothe FS®, marketed by Hill Dermaceuticals; and Psorcon®, marketed by Dermik Laboratories, Inc. In February 2003, Biogen announced that the FDA had approved its systemic drug, Amevive, for the treatment of psoriasis. In addition, both OLUX and Luxíq compete with generic (non-branded) pharmaceuticals, which claim to offer equivalent therapeutic benefits at a lower cost. In some cases, insurers and other third-party payors seek to encourage the use of generic products making branded products less attractive, from a cost perspective, to buyers.

     Many of our existing or potential competitors, particularly large pharmaceutical companies, have substantially greater financial, technical and human resources than we do. In addition, many of these competitors have more collective experience than we do in undertaking preclinical testing and human clinical trials of new pharmaceutical products and obtaining regulatory approvals for therapeutic products. Accordingly, our competitors may succeed in obtaining FDA approval for products more rapidly or successfully than we do.

     We intend to compete on the basis of the quality and efficacy of our products and unique drug delivery vehicles, combined with the effectiveness of our marketing and sales efforts. Competing successfully will depend on our continued ability to attract and retain skilled and experienced personnel, to identify, secure the rights to, and develop pharmaceutical products and compounds, and to exploit these products and compounds commercially before others are able to develop competitive products.

CUSTOMERS

     We sell product directly to wholesale distributors. Patients have their prescriptions filled by pharmacies that buy the drug from the wholesalers. Accordingly, the number of prescriptions written for our products only indirectly affects our product revenues. Our customers include the nation’s leading wholesale pharmaceutical distributors, such as McKesson HBOC, Inc., Cardinal Health, Inc., and AmerisourceBergen Corporation, and major drug chains. During 2002, Cardinal Health, McKesson, and AmerisourceBergen accounted for 43%, 26%, and 23%, respectively, of our gross product revenues. The distribution network for pharmaceutical products is subject to increasing consolidation. As a result, a few large wholesale distributors control a significant share of the market. In addition, the number of independent drug stores and small chains has decreased as retail consolidation has occurred. Further consolidation among, or any financial difficulties of, distributors or retailers could result in the combination or elimination of warehouses, which may result in reductions in purchases of our products, returns of our products, or cause a reduction in the inventory levels of distributors and retailers, any of which could have a material adverse impact on our business. If we lose any of these customer accounts, or if our relationship with them were to deteriorate, our business could also be materially and adversely affected.

RESEARCH AND DEVELOPMENT AND PRODUCT PIPELINE

     Innovation by our research and development operations is very important to the success of our business. Our research and development expenses were $25.8 million in 2002, $19.2 million in 2001, and $21.9 million in 2000. Our goal is to discover, develop and bring to market innovative products that address unmet healthcare needs. Our substantial investment in research and development supports this goal. We have the rights to a variety of pharmaceutical agents in various stages of pre-clinical and clinical development in several novel delivery technologies.

     Our development activities involve work related to product formulation, preclinical and clinical study coordination, regulatory administration, manufacturing, and quality control and assurance. Many pharmaceutical companies conduct early stage research and drug discovery, but to obtain the most value from our development portfolio, we are focusing on later-stage development. This approach helps to minimize the risk and time requirements for us to get a product on the market. Our strategy involves targeting product candidates that we believe have large market potential, and then rapidly evaluating and formulating new therapeutics by using previously approved active ingredients reformulated in our proprietary delivery system. This product development strategy allows us to conduct limited preclinical safety trials, and to move rapidly into safety and efficacy testing in

7

Table of Contents

humans with products that offer significant improvements over existing products. A secondary strategy is to evaluate the acquisition of products from other companies.

     We have developed several additional aerosol foams similar to our foam delivery system for OLUX and Luxíq, including water-, ethanol- and petrolatum-based foams. We have also developed Liquipatch, a multi-polymer gel-matrix delivery system that applies to the skin like a normal gel and dries to form a very thin, invisible, water-resistant film. This film enables a controlled release of the active agent, which we believe will provide a longer treatment period. We anticipate developing one or more new products in the aerosol foam or Liquipatch formulations, by incorporating leading dermatologic agents in formulations that are tailored to treat specific diseases or different areas of the body.

     All products and technologies under development require significant commitments of personnel and financial resources. In addition to our in-house staff and resources, we contract a substantial portion of development work to outside parties. For example, we typically engage contract research organizations to manage our clinical trials. We have contracts with vendors to conduct product analysis and stability studies, and we outsource all of our manufacturing scale-up and production activities. We also use collaborative relationships with pharmaceutical partners and academic researchers to augment our product development activities, and from time to time we enter into agreements with academic or university-based researchers to conduct various studies for us.

PATENTS AND PROPRIETARY RIGHTS

     Our success will depend in part on our ability and our licensors’ ability to obtain and retain patent protection for our products and processes, to preserve our trade secrets, and to operate without infringing the proprietary rights of third parties. We are pursuing several U. S. and international patent applications, although we cannot be sure that any of these patents will ever be issued. We also have acquired rights from the assignment of rights to patents and patent applications from certain of our consultants and officers. These patents and patent applications may be subject to claims of rights by third parties. If there are conflicting claims to the same patent or patent application, we may not prevail and, even if we do have some rights in a patent or application, those rights may not be sufficient for the marketing and distribution of products covered by the patent or application.

     We own or are exclusively licensed under pending applications and/or issued patents worldwide relating to OLUX and Luxíq, recombinant human relaxin, and other products in the earlier stages of research. We own over 20 patents related to the technologies developed by Connetics Australia, expiring between 2003 and 2018, and we have several pending applications.

     The delivery technology that is the basis for OLUX and Luxíq is covered by a U.S. patent on methods of treating various skin diseases using a foam pharmaceutical composition comprising a corticosteroid active substance, a propellant and a buffering agent. The Liquipatch technology is covered by one U.S. patent.

     With respect to patent applications that we or our licensors have filed, and patents issued to us or our licensors, we cannot assure you that:

	•		any of our or our licensors’ patent applications will issue as patents,
	•		any issued patents will provide competitive advantage to us, or
	•		our competitors will not successfully challenge or circumvent any issued patents.

     We rely on and expect to continue to rely on unpatented proprietary know-how and continuing technological innovation in the development and manufacture of many of our principal products. We require all our employees, consultants and advisors to enter into confidentiality agreements with us. These agreements, however, may not provide adequate protection for our trade secrets or proprietary know-how in the event of any unauthorized use or disclosure of such information. In addition, others may obtain access to or independently develop similar or equivalent trade secrets or know-how.

TRADEMARKS

     We believe that trademark protection is an important part of establishing product and brand recognition. We own 12 registered trademarks and several trademark applications and common law trademarks. United States federal registrations for trademarks remain in force for 10 years and may be renewed every 10 years after issuance, provided the mark is still being used in commerce. However, any such trademark or service mark registrations may not afford us adequate protection, and we may not have the financial resources to enforce our rights under any such trademark or service mark registrations. If we are unable to protect our trademarks or service marks from infringement, any goodwill developed in such trademarks or service marks could be impaired.

MANUFACTURING

     We do not operate manufacturing or distribution facilities for any of our products. Instead, we contract with third parties to manufacture our products for us. Company policy and the FDA require that we contract only with manufacturers that comply with current Good Manufacturing Practice, or cGMP, regulations and other applicable laws and regulations. Currently, DPT, Miza Pharmaceuticals and Accra Pac Group, Inc. manufacture commercial supplies of OLUX and Luxíq, as well as physician samples of those products for us. DPT also manufactures clinical supplies for our various clinical trial programs. On March 12, 2002, we entered into agreements with DPT to construct an aerosol filling line at DPT’s plant in Texas and to manufacture and fill our commercial aerosol products. The aerosol line was completed in September 2002, and effective February 21, 2003, is approved for the manufacture of OLUX in the United States. We anticipate that DPT will be approved to manufacture Luxíq commercially in the spring of 2003.

WAREHOUSING AND DISTRIBUTION

     Currently, all of our product distribution activities are handled by Cardinal Health Specialty Pharmaceutical Services (formerly CORD Logistics, Inc.). Cardinal Health Specialty Pharmaceutical Services, or SPS, is a division of Cardinal Health, which was our largest customer in 2002. For more information about our customers, see “Customers” above, and Note 2 of Notes to Consolidated Financial Statements. SPS stores and distributes products to our customers from a warehouse in Tennessee. When SPS receives a purchase order, it processes the order into a computerized distribution database. Generally, our customers’ orders are shipped from SPS within 24 hours after their order is received. Once the order has shipped, SPS generates and mails out invoices on our behalf. Any delay or interruption in the distribution process or in payment by our customers could have a material effect on our business.

GOVERNMENT REGULATION

     Generally – Product Development. The pharmaceutical industry is subject to regulation by the FDA under the Food, Drug and Cosmetic Act, by the states under state food and drug laws, and by similar agencies outside of the United States. In order to clinically test, manufacture, and market products for therapeutic use, we must satisfy mandatory procedures and safety and effectiveness standards established by various regulatory bodies. We have provided a more detailed explanation of the standard we are subject to under “Factors Affecting Our Business and Prospects — We may spend a significant amount of money to obtain FDA and other regulatory approvals, which may never be granted” and “— We cannot sell our current products and product candidates if we do not obtain and maintain governmental approvals” below.

     We expect that all of our prescription pharmaceutical products will require regulatory approval by governmental agencies before we can commercialize them, although the nature and extent of the review process for our potential products will vary depending on the regulatory categorization of particular products. Federal, state, and international regulatory bodies govern or influence, among other things, the testing, manufacture, labeling, storage, record keeping, approval, advertising, and promotion of our products on a product-by-product basis. Failure to comply with applicable requirements can result in, among other things, warning letters, fines, injunctions, penalties, recall or seizure of products, total or partial suspension of production, denial or withdrawal of approval, and criminal prosecution. Accordingly, ongoing regulation by governmental entities in the United States and other countries will be a significant factor in the production and marketing of any pharmaceutical products that we have or may develop.

Table of Contents

     Product development and approval within this regulatory framework, and the subsequent compliance with appropriate federal and foreign statutes and regulations, takes a number of years and involves the expenditure of substantial resources. Generally, a company must conduct pre-clinical studies before it can obtain FDA approval for a new therapeutic agent. The basic purpose of pre-clinical investigation is to gather enough evidence on the potential new agent through laboratory experimentation and animal testing, to determine if it is reasonably safe to begin preliminary trials in humans. The sponsor of these studies submits the results to the FDA as a part of an investigational new drug application, which the FDA must review before human clinical trials of an investigational drug can start. We have filed and will continue to be required to sponsor and file investigational new drug applications, and will be responsible for initiating and overseeing the clinical studies to demonstrate the safety and efficacy that are necessary to obtain FDA approval of our product candidates.

     Clinical trials are normally done in phases and generally take two to five years, but may take longer, to complete. Phase I trials generally involve administration of a product to a small number of patients to determine safety, tolerance and the metabolic and pharmacologic actions of the agent in humans and the side effects associated with increasing doses. Phase II trials generally involve administration of a product to a larger group of patients with a particular disease to obtain evidence of the agent’s effectiveness against the targeted disease, to further explore risk and side effect issues, and to confirm preliminary data regarding optimal dosage ranges. Phase III trials involve more patients, and often more locations and clinical investigators than the earlier trials. At least one such trial is required for FDA approval to market a drug.

     The rate of completion of our clinical trials depends upon, among other factors, the rate at which patients enroll in the study. Patient enrollment is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites and the eligibility criteria for the study. Delays in planned patient enrollment may result in increased costs and delays, which could have a material adverse effect on our business. In addition, side effects or adverse events that are reported during clinical trials can delay, impede, or prevent marketing approval.

     The Food, Drug and Cosmetic Act includes provisions for accelerating the FDA approval process under certain circumstances. For example, we used the so-called 505(b)(2) application process for both OLUX and Luxíq, which permitted us to satisfy the requirements for a full NDA by relying on published studies or the FDA’s findings of safety and effectiveness based on studies in a previously-approved NDA sponsored by another applicant, together with the studies generated on our products. While the FDA evaluation used the same standards of approval as an NDA, the number of clinical trials required to support a 505(b)(2) application, and the amount of information in the application itself, may be substantially less than that required to support an NDA application. The 505(b)(2) process will not be available for all of our other product candidates, and as a result the FDA process may be longer for those product candidates than it was for OLUX and Luxíq.

     After we complete the clinical trials of a new drug product, we must file an NDA with the FDA. We must receive FDA clearance before we can commercialize the product, and the FDA may not grant approval on a timely basis or at all. The FDA can take between one and two years to review an NDA, and can take longer if significant questions arise during the review process. In addition, if there are changes in FDA policy while we are in product development, we may encounter delays or rejections that we did not anticipate when we submitted the new drug application for that product. We may not obtain regulatory approval for any products that we develop, even after committing such time and expenditures to the process. Even if regulatory approval of a product is granted, it may entail limitations on the indicated uses for which the product may be marketed.

     Our products will also be subject to foreign regulatory requirements governing human clinical trials, manufacturing and marketing approval for pharmaceutical products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement are similar, but not identical, to FDA requirements, and they vary widely from country to country.

     Manufacturing. The FDA regulates and inspects equipment, facilities, and processes used in the manufacturing of pharmaceutical products before providing approval to market a product. If after receiving clearance from the FDA, we make a material change in manufacturing equipment, location, or process, we may have to undergo additional regulatory review. We must apply to the FDA to change the manufacturer we use to produce

10

Table of Contents

any of our products. We and our contract manufacturers must adhere to cGMP and product-specific regulations enforced by the FDA through its facilities inspection program. The FDA also conducts regular, periodic visits to re-inspect equipment, facilities, and processes after the initial approval. If, as a result of these inspections, the FDA determines that our (or our contract manufacturers’) equipment, facilities, or processes do not comply with applicable FDA regulations and conditions of product approval, the FDA may seek sanctions and/or remedies against us, including suspension of our manufacturing operations.

     Post-Approval Regulation. The FDA continues to review marketed products even after granting regulatory clearances, and if previously unknown problems are discovered or if we fail to comply with the applicable regulatory requirements, the FDA may restrict the marketing of a product or impose the withdrawal of the product from the market, recalls, seizures, injunctions or criminal sanctions. In its regulation of advertising, the FDA from time to time issues correspondence to pharmaceutical companies alleging that some advertising or promotional practices are false, misleading or deceptive. The FDA has the power to impose a wide array of sanctions on companies for such advertising practices.

     Pharmacy Boards. We are required in most states to be licensed with the state pharmacy board as either a manufacturer, wholesaler, or wholesale distributor. Many of the states allow exemptions from licensure if our products are distributed through a licensed wholesale distributor. The regulations of each state are different, and the fact that we are licensed in one state does not authorize us to sell our products in other states. Accordingly, we undertake an annual review of our license status and that of SPS to ensure continued compliance with the state pharmacy board requirements.

     Fraud and Abuse Regulations. We are subject to various federal and state laws pertaining to health care “fraud and abuse,” including anti-kickback laws and false claims laws. Anti-kickback laws make it illegal for a prescription drug manufacturer to solicit, offer, receive, or pay any remuneration in exchange for, or to induce, the referral of business, including the purchase or prescription of a particular drug. The federal government has published regulations that identify “safe harbors” or exemptions for certain payment arrangements that do not violate the anti-kickback statutes. We seek to comply with the safe harbors where possible. Due to the breadth of the statutory provisions and the absence of guidance in the form of regulations or court decisions addressing some of our practices, it is possible that our practices might be challenged under anti-kickback or similar laws. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented for payment to third party payors (including Medicare and Medicaid) claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services. Our activities relating to the sale and marketing of our products may be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as the possibility of exclusion from federal health care programs (including Medicare and Medicaid).

     We participate in the Federal Medicaid rebate program established by the Omnibus Budget Reconciliation Act of 1990, as well as several state supplemental rebate programs. Under the Medicaid rebate program, we pay a rebate to each state Medicaid program for our products that are reimbursed by those programs. As a manufacturer currently of single source products only, the amount of the rebate for each of our products is set by law as the greater of 15.1% of the average manufacturer price of that product, or the difference between the average manufacturer price and the best price available from the company to any customer, with the final rebate amount adjusted upward if increases in average manufacturer price since product launch have outpaced inflation. The Medicaid rebate amount is computed each quarter based on our submission to the United States Department of Health and Human Services Centers for Medicare and Medicaid Services of our current average manufacturer price and best price for each of our products. As part of our revenue recognition policy, we provide reserves on this potential exposure at the time of product shipment.

     Federal law also requires that any company that participates in the Medicaid program must extend comparable discounts to qualified purchasers under the Public Health Services, or PHS, pharmaceutical pricing program. The PHS pricing program extends discounts comparable to the Medicaid rebate to a variety of community health clinics and other entities that receive health services grants from the PHS, as well as hospitals that serve a disproportionate share of poor Medicare and Medicaid beneficiaries.

11

Table of Contents

     We also make our products available to authorized users of the Federal Supply Schedule, of FSS, of the General Services Administration under an FSS contract negotiated by the Department of Veterans Affairs. The Veterans Health Care Act of 1992, or VHCA, imposes a requirement that the prices a company such as Connetics charges the Veterans Administration, the Department of Defense, the Coast Guard, and the PHS be discounted by a minimum of 24% off the average manufacturer price charged to non-federal customers. Our computation of the average price to non-federal customers is used in establishing the FSS price for these four purchasers. The government maintains the right to audit the accuracy of our computations. Among the remedies available to the government for failure to accurately calculate FSS pricing and the average manufacturer price charged to non-federal customers is recoupment of any overpayments made by FSS purchasers as a result of errors in computations that affect the FSS price.

     The Medicaid rebate statute and the VHCA also provide that, in addition to penalties that may be applicable under other federal statutes, civil monetary penalties may be assessed for knowingly providing false information in connection with the pricing and reporting requirements under the laws. The amount that may be assessed is up to $100,000 for each item of false information. We have provided additional information about the risks associated with participation in the Medicaid and similar programs, under “Factors Affecting Our Business and Prospects – Our sales depend on payment and reimbursement from third party payors, and if they reduce or refuse payment or reimbursement, the use and sales of our products will suffer, we may not increase our market share, and our revenues and profitability will suffer” and “—The growth of managed care organizations and other third-party reimbursement policies may have an adverse effect on our pricing policies and our margins” below.

MARKETING TO HEALTHCARE PROFESSIONALS

     A number of guidelines were issued in 2002 relating to how pharmaceutical manufacturers interact with doctors and other healthcare professionals. We intend for our relationships with doctors to benefit patients and to enhance the practice of medicine, and at the same time represent the interests of our stockholders in maintaining and growing our company. We have adopted internal policies that emphasize to our employees that all interactions with healthcare professionals should be focused on informing them about our products, providing scientific and educational information, or supporting medical research and education. Recent draft guidance issued by the Office of Inspector General of Health and Human Services recommends significant restrictions on how pharmaceutical companies can interact with the medical community. We believe that effective marketing of our products is necessary to ensure that patients have access to the products they need, and that the products are correctly used for maximum patient benefit. Our marketing and sales organization is critical to achieving these goals, because they foster relationships that enable us to inform healthcare professionals about the benefits and risks of our products, provide scientific and educational information, support medical research and education, and obtain feedback and advice about our products through consultation with medical experts. We intend to closely follow developments in this field, and to continue to assess the impact that any new regulations might have on our business.

MARKETING EXCLUSIVITY

     The FDA has the power to grant pharmaceutical companies new drug product exclusivity for a drug, independent of any orphan drug or patent term exclusivity accorded to that drug. This marketing exclusivity essentially prevents competition from other manufacturers who wish to put generic versions of the product into U.S. commerce. The FDA has granted us marketing exclusivity for foam-based products incorporating clobetasol propionate until May 26, 2003. The exclusivity prevents other parties from submitting or getting approval for any application before the exclusive period expires. The FDA determines whether a drug is eligible for exclusivity on a case-by-case basis. The FDA may grant three-year exclusivity provided that the application included at least one new clinical investigation other than bioavailability studies, the investigation was conducted or sponsored by the drug company, and the reports of the clinical investigation were essential to the approval of the application. At the time we submitted the sNDA for the expanded label for OLUX, we requested exclusivity for the new indication. The FDA has not advised us of its position on that issue.

THIRD PARTY REIMBURSEMENT

     Our operating results will depend in part on whether adequate reimbursement is available for our products from third-party payors, such as government entities, private health insurers and managed care organizations.

12

Table of Contents

     Medicare, Medicaid, health maintenance organizations and other third-party payors may not authorize or otherwise budget such reimbursement. Because of the size of the patient population covered by managed care organizations, marketing of prescription drugs to them and the pharmacy benefit managers that serve many of these organizations is important to our business. Managed care organizations and other third-party payors try to negotiate the pricing of medical services and products to control their costs. Managed care organizations and pharmacy benefit managers typically develop formularies to reduce their cost for medications. Due to their lower costs, generic products are often favored on such formularies. The breadth of the products covered by formularies varies considerably from one managed care organization to another, and many formularies include alternative and competitive products for treatment of particular medical conditions. The exclusion of a product from a formulary can sharply reduce usage of that product in the managed care organization’s patient population. In some cases, third-party payors will pay or reimburse users or suppliers of a prescription drug product only a portion of the product purchase price. Consumers and third-party payors may not view our marketed products as cost-effective, and consumers may not be able to get reimbursement or reimbursement may be so low that we cannot market our products on a competitive basis. If managed care organizations or other third-party payors do not provide adequate reimbursement levels for our products, or if those reimbursement policies predominantly favor the use of generic products, our sales could decline and our business could be seriously harmed.

     Furthermore, federal and state regulations govern or influence the reimbursement to health care providers of fees in connection with medical treatment of certain patients. We cannot predict the likelihood that federal and state legislatures will pass laws related to health care reform or lowering pharmaceutical costs. Continued significant changes in the health care system could have a material adverse effect on our business.

RELAXIN DEVELOPMENT PROGRAM

Overview

     In addition to our commercial business, we own the development and commercialization rights to a recombinant form of a natural human hormone called relaxin. Relaxin reduces the hardening, or fibrosis, of skin and organ tissue, dilates existing blood vessels and stimulates new blood vessel growth. Relaxin circulates in the blood and has a broad spectrum of biological activities.

     In October 2000, we announced that our pivotal trial for scleroderma showed no statistically significant difference between the response to relaxin and the response to placebo with respect to the “primary endpoint” of that trial. There were, however, statistically significant responses with respect to secondary parameters measured in that trial. Infertility, peripheral vascular disease, cardiovascular disease, and kidney disease represent opportunities for relaxin’s biologic properties of enhancing blood flow.

     Based on the result of the pivotal trial, and following an extensive evaluation of other potential uses for relaxin, on May 23, 2001, we announced our decision to reduce our investment in relaxin in favor of focusing our resources on expanding our dermatology business, and to pursue a license partner or other strategic alternative for the relaxin program. As part of that decision we reduced our work force by eliminating 27 positions related to relaxin. Prior to May 2001, our strategy had been to retain U.S. rights for all potential indications for the drug. We maintain North American rights for relaxin and have entered into collaborative relationships for this program for markets outside of the United States. We have licensed rights to relaxin development and commercialization to Paladin Labs, Inc. for Canada, and to F.H. Faulding & Co. for Australia.

Relaxin Alliances

     Canadian and Australian Licenses. In July 1999, we entered into a collaboration and exclusive license agreement with Paladin Labs, Inc. for the development and commercialization of relaxin in Canada. In April 2000, we entered into a collaboration and exclusive license agreement with Faulding for the development and commercialization of relaxin in Australia. Although we have discontinued our development efforts for relaxin for scleroderma, Paladin and Faulding have indicated that they will continue the collaboration for other indications. Under the terms of the agreements, Paladin and Faulding would owe additional milestone payments for the approval of non-scleroderma indications for relaxin in Canada and Australia, respectively. Paladin is responsible for all development and commercialization activities in Canada, and is obligated to pay royalties on all sales of relaxin in

13

Table of Contents

Canada. Faulding is responsible for all development and commercialization activities in Australia, and will pay royalties on all sales of relaxin in Australia. In October 2001, Faulding was acquired by Mayne Group Limited, Australia’s largest private health care provider.

     Genentech. We are party to an agreement with Genentech which grants to us exclusive rights, for indications other than reproductive indications, to make, have made, use, import and sell certain products derived from recombinant human relaxin. Many of our relaxin patent rights are owned by The Florey Institute, and we license them through Genentech. Genentech retains co-exclusive rights for reproductive indications. The agreement also includes technology transfer, supply, and intellectual property provisions, including a provision requiring us to meet milestones. If we fail to achieve designated milestones, Genentech may terminate the license. Upon termination, the patent rights and know-how we licensed from Genentech would revert to Genentech, and under certain circumstances depending on the reason for the termination, Genentech would automatically receive a non-exclusive, sublicensable and fully paid up license to our relaxin technology.

ENVIRONMENTAL REGULATION

     Our research and development activities involve the controlled use of hazardous and biohazardous materials, chemicals such as solvents and active pharmaceutical agents, compressed gases, and certain radioactive materials, such as hydrogen-3, carbon-14, and phosphorous-33. We are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of such materials and certain waste products. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state, federal, and local laws and regulations, we cannot completely eliminate the risk of accidental contamination or injury from these materials.

     Compliance with federal, state and local laws regarding the discharge of materials into the environment or otherwise relating to the protection of the environment has not had, and is not expected to have, any adverse effect on our capital expenditures, earnings or competitive position. We are not presently a party to any litigation or administrative proceeding with respect to our compliance with such environmental standards. In addition, we do not anticipate being required to expend any funds in the near future for environmental protection in connection with our operations.

EMPLOYEES

     As of March 3, 2003, we had 190 full-time employees. Of the full-time employees, 76 were engaged in sales and marketing, 79 were in research and development and 35 were in general and administrative positions. We believe our relations with our employees are good.

FACTORS AFFECTING OUR BUSINESS AND PROSPECTS

     There are many factors that affect our business and results of operations, some of which are beyond our control. The following describes some of the important factors that may cause the actual results of our operations in future periods to differ materially from the results currently expected or desired, and so materially affect our future developments and performance. This list of factors that may affect future performance and the accuracy of forward-looking statements is illustrative, but not exhaustive. Accordingly, you should evaluate all forward-looking statements with the understanding of their inherent uncertainty. Due to the foregoing factors, we believe that quarter-to-quarter comparisons of our results of operations are not a good indication of our future performance.

Risks Related To Our Business

Our operating results may fluctuate, and this fluctuation could cause financial results to be below expectations.

     Our operating results may fluctuate from period to period for a number of reasons, and even a relatively small revenue shortfall may cause a period’s results to be below our expectations or projections. A revenue shortfall could arise from any number of factors, some of which we cannot control. For example, we may face:

•

lower than expected demand for our products,

14

Table of Contents

	•		changes in the government’s or private payors’ reimbursement policies for our products,
	•		changes in wholesale buying patterns,
	•		increases in returns of our product, or rebates paid for our products,
	•		increased competition from new or existing products, or
	•		changes in our product pricing strategies.

Of these, we would only have control over changes in our product pricing strategies, and of course there may be other factors that affect our revenues in any given period.

If we do not obtain the capital necessary to fund our operations, we will be unable to develop or market our products.

     Product revenue from sales of our marketed products does not currently cover the full cost of developing products in our pipeline. We currently believe that our available cash resources will be sufficient to fund our operating and working capital requirements for at least the next 12 months. If in the future our product revenue does not continue to grow or we are unable to raise additional funds when needed, we may not be able to market our products as planned or continue development of our other products. Accordingly, we may need to raise additional funds through public or private financings, strategic relationships or other arrangements.

If we do not achieve and sustain profitability, stockholders may lose their investment.

     Except for fiscal year 2000, we have lost money every year since our inception. We had net losses of $27.3 million in 1999, $16.0 million in 2000 (after excluding a one-time gain of $43.0 million on sales of stock we held in InterMune, and the associated income tax), $16.7 million in 2001, and $16.6 million for the year ended December 31, 2002. Our accumulated deficit was $126.1 million at December 31, 2002. We may incur additional losses during the next few years. If we do not eventually achieve and maintain profitability, our stock price may decline.

Our total revenue depends on receiving royalties and contract payments from third parties, and we cannot control the amount or timing of those revenues.

     We generate contract and royalty revenue by licensing our products to third parties for specific territories and indications. Our reliance on licensing arrangements with third parties carries several risks, including the possibilities that:

	•		a product development contract may expire or a relationship may be terminated, and we will not be able to attract a satisfactory alternative corporate partner within a reasonable time,
	•		we may be contractually bound to terms that, in the future, are not commercially favorable to us, and
	•		royalties generated from licensing arrangements may be insignificant.

If any of these events occurs, we may not be able to successfully develop our products.

If we fail to protect our proprietary rights, competitors may be able to use our technologies, which would weaken our competitive position, reduce our revenues and increase our costs.

     We believe that the protection of our intellectual property, including patents and trademarks, is an important factor in product recognition, maintaining goodwill, and maintaining or increasing market share. If we do not adequately protect our rights in our trademarks from infringement, any goodwill which has been developed in those marks could be lost or impaired. If the marks we use are found to infringe upon the trademark of another company, we could be forced to stop using those marks, and as a result we could lose all the goodwill which has been developed in those marks and could be liable for damaged caused by an infringement.

Table of Contents

     Our commercial success depends in part on our ability and the ability of our licensors to obtain and maintain patent protection on technologies, to preserve trade secrets, and to operate without infringing the proprietary rights of others.

     We are pursuing several U. S. and international patent applications, although we cannot be sure that any of these patents will ever be issued. We also have acquired rights from the assignment of rights to patents and patent applications from certain of our consultants and officers. These patents and patent applications may be subject to claims of rights by third parties. If there are conflicting claims to the same patent or patent application, we may not prevail and, even if we do have some rights in a patent or application, those rights may not be sufficient for the marketing and distribution of products covered by the patent or application.

     The patents and applications in which we have an interest may be challenged as to their validity or enforceability. Challenges may result in potentially significant harm to our business. The cost of responding to these challenges and the inherent costs to defend the validity of our patents, including the prosecution of infringements and the related litigation, could be substantial whether or not we are successful. Such litigation also could require a substantial commitment of management’s time. A judgment adverse to us in any patent interference, litigation or other proceeding arising in connection with these patent applications could materially harm our business.

     The ownership of a patent or an interest in a patent does not always provide significant protection. Others may independently develop similar technologies or design around the patented aspects of our technology. We only conduct patent searches to determine whether our products infringe upon any existing patents when we think such searches are appropriate. As a result, the products and technologies we currently market, and those we may market in the future, may infringe on patents and other rights owned by others. If we are unsuccessful in any challenge to the marketing and sale of our products or technologies, we may be required to license the disputed rights, if the holder of those rights is willing, or to cease marketing the challenged products, or to modify our products to avoid infringing upon those rights. Under these circumstances, we may not be able to obtain a license to such intellectual property on favorable terms, if at all. We may not succeed in any attempt to redesign our products or processes to avoid infringement.

We rely on our employees and consultants to keep our trade secrets confidential.

     We rely on trade secrets and unpatented proprietary know-how and continuing technological innovation in developing and manufacturing our products. We require each of our employees, consultants and advisors to enter into confidentiality agreements prohibiting them from taking our proprietary information and technology or from using or disclosing proprietary information to third parties except in specified circumstances. The agreements also provide that all inventions conceived by an employee, consultant or advisor, to the extent appropriate for the services provided during the course of the relationship, shall be our exclusive property, other than inventions unrelated to us and developed entirely on the individual’s own time. Nevertheless, these agreements may not provide meaningful protection of our trade secrets and proprietary know-how if they are used or disclosed. Despite all of the precautions we may take, people who are not parties to confidentiality agreements may obtain access to our trade secrets or know-how. In addition, others may independently develop similar or equivalent trade secrets or know-how.

If we do not successfully partner or commercialize relaxin, we may lose fundamental intellectual property rights to the product.

     Licenses with Genentech, Inc. and The Howard Florey Institute of Experimental Physiology and Medicine require us to use our best efforts to commercialize relaxin. If we fail to successfully commercialize relaxin, our rights under these licenses may revert to Genentech and the Florey Institute. The termination of these agreements and subsequent reversion of rights could prevent us from leveraging our additional patents and know-how by securing a partnership arrangement for the relaxin program.

Our use of hazardous materials exposes us to the risk of environmental liabilities, and we may incur substantial additional costs to comply with environmental laws.

     Our research and development activities involve the controlled use of hazardous materials, chemicals and various radioactive materials. We are subject to laws and regulations governing the use, storage, handling and disposal of these materials and certain waste products. In the event of accidental contamination or injury from these materials, we could be liable for any damages that result and any liability could exceed our resources. We may also be required to incur significant costs to comply with environmental laws and regulations as our research activities increase.

Risks Related To Our Products

Future manufacturing difficulties could delay future revenues from product sales of OLUX and Luxíq.

     Manufacturing facilities are subject to ongoing periodic inspection by the FDA and corresponding state agencies, including unannounced inspections, and must be licensed before they can be used in commercial manufacturing of our products. If DPT, AccraPac or Miza cannot provide us with our product requirements in a timely and cost-effective manner, or if the product they are able to supply cannot meet commercial requirements for shelf life, our sales of marketed products could be reduced and we could suffer delays in the progress of clinical trials for products under development. In addition, any commercial dispute with any of our suppliers could result in delays in the manufacture of product, and affect our ability to commercialize our products. We cannot be certain that manufacturing sources will continue to be available or that we can continue to out-source the manufacturing of our products on reasonable or acceptable terms. Any loss of a manufacturer or any difficulties that could arise in the manufacturing process could significantly affect our inventories and supply of products available for sale. If we are unable to supply sufficient amounts of our products on a timely basis, our market share could decrease and, correspondingly, our profitability could decrease.

If our contract manufacturers fail to comply with cGMP regulations, we may be unable to meet demand for our products and may lose potential revenue.

     All of our contractors must comply with the applicable FDA cGMP regulations, which include quality control and quality assurance requirements as well as the corresponding maintenance of records and documentation. If our contract manufacturers do not comply with the applicable cGMP regulations and other FDA regulatory requirements, our sales of marketed products could be reduced and we could suffer delays in the progress of clinical trials for products under development. We do not have control over our third-party manufacturers’ compliance with these regulations and standards. Our business interruption insurance, which covers the loss of income for up to $10.0 million, may not completely mitigate the harm to our business from the interruption of the manufacturing of products caused by certain events, as the loss of a manufacturer could still have a negative effect on our sales, margins and market share, as well as our overall business and financial results.

If our supply of finished products is interrupted, our ability to maintain our inventory levels could suffer.

     We try to maintain inventory levels that are no greater than necessary to meet our current projections. Any interruption in the supply of finished products could hinder our ability to timely distribute finished products. If we are unable to obtain adequate product supplies to satisfy our customers’ orders, we may lose those orders and our customers may cancel other orders and stock and sell competing products. This in turn could cause a loss of our market share and negatively affect our revenues.

     Supply interruptions may occur and our inventory may not always be adequate. Numerous factors could cause interruptions in the supply of our finished products including shortages in raw material required by our manufacturers, changes in our sources for manufacturing, our failure to timely locate and obtain replacement manufacturers as needed and conditions effecting the cost and availability of raw materials.

We cannot sell our current products and product candidates if we do not obtain and maintain governmental approvals.

     Pharmaceutical companies are subject to heavy regulation by a number of national, state and local agencies. Of particular importance is the FDA in the United States. It has jurisdiction over all of our business and administers requirements covering testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of our products. Failure to comply with applicable regulatory requirements could, among other things, result in fines; suspensions of regulatory approvals of products; product recalls; delays in product distribution, marketing and sale; and civil or criminal sanctions.

     The process of obtaining and maintaining regulatory approvals for pharmaceutical products, and obtaining and maintaining regulatory approvals to market these products for new indications, is lengthy, expensive and uncertain. The manufacturing and marketing of drugs, including our products, are subject to continuing FDA and foreign regulatory review, and later discovery of previously unknown problems with a product, manufacturing process or facility may result in restrictions, including withdrawal of the product from the market. The FDA is permitted to revisit and change its prior determinations and it may change its position with regard to the safety or effectiveness of our products. Even if the FDA approves our products, the FDA is authorized to impose post-marketing requirements such as:

	•		testing and surveillance to monitor the product and its continued compliance with regulatory requirements,
	•		submitting products for inspection and, if any inspection reveals that the product is not in compliance, the prohibition of the sale of all products from the same lot,
	•		suspending manufacturing,
	•		recalling products, and
	•		withdrawing marketing approval.

Even before any formal regulatory action, we could voluntarily decide to cease distribution and sale or recall any of our products if concerns about the safety or effectiveness develop.

     To market our products in countries outside of the United States, we and our partners must obtain similar approvals from foreign regulatory bodies. The foreign regulatory approval process includes all of the risks associated with obtaining FDA approval, and approval by the FDA does not ensure approval by the regulatory authorities of any other country.

     In its regulation of advertising, the FDA from time to time issues correspondence to pharmaceutical companies alleging that some advertising or promotional practices are false, misleading or deceptive. The FDA has the power to impose a wide array of sanctions on companies for such advertising practices, and the receipt of correspondence from the FDA alleging these practices can result in the following:

	•		incurring substantial expenses, including fines, penalties, legal fees and costs to comply with the FDA’s requirements,
	•		changes in the methods of marketing and selling products,
	•		taking FDA-mandated corrective action, which may include placing advertisements or sending letters to physicians rescinding previous advertisements or promotion, and
	•		disruption in the distribution of products and loss of sales until compliance with the FDA’s position is obtained.

     In recent years, various legislative proposals have been offered in Congress and in some state legislatures that include major changes in the health care system. These proposals have included price or patient reimbursement constraints on medicines and restrictions on access to certain products. We cannot predict the outcome of such initiatives, and it is difficult to predict the future impact of the broad and expanding legislative and regulatory requirements affecting us.

We may spend a significant amount of money to obtain FDA and other regulatory approvals, which may never be granted.

     Successful product development in our industry is highly uncertain, and the process of obtaining FDA and other regulatory approvals is lengthy and expensive. Very few research and development projects produce a commercial product. Product candidates that appear promising in the early phases of development may fail to reach the market for a number of reasons, including that the product candidate did not demonstrate acceptable clinical trial results even though it demonstrated positive preclinical trial results, or that the product candidate was not effective in treating a specified condition or illness, or that the FDA did not approve our product candidate for its intended use.

     To obtain approval, we must show in preclinical and clinical trials that our products are safe and effective. The FDA approval processes require substantial time and effort, the FDA continues to modify product development guidelines, and the FDA may not grant approval on a timely basis or at all. Clinical trial data can be the subject of differing interpretation, and the FDA has substantial discretion in the approval process. The FDA may not interpret our clinical data the way we do. The FDA may also require additional clinical data to support approval. The FDA can take between one and two years to review new drug applications, or longer if significant questions arise during the review process. We may not be able to obtain FDA approval to conduct clinical trials or to manufacture and market any of the products we develop, acquire or license. Moreover, the costs to obtain approvals could be considerable and the failure to obtain or delays in obtaining an approval could have a significant negative effect on our business.

If OLUX and Luxíq do not sustain market acceptance, our revenues will not be predictable and may not cover our operating expenses.

     Our future revenues will depend upon dermatologist and patient acceptance of OLUX and Luxíq. Factors that could affect acceptance of OLUX and Luxíq include:

	•		satisfaction with existing alternative therapies,
	•		the effectiveness of our sales and marketing efforts,
	•		the cost of the product as compared with alternative therapies, and
	•		undesirable and unforeseeable side effects.

We cannot predict the potential long-term patient acceptance of, or the effects of competition and managed health care on, sales of either product.

We rely on third parties to conduct clinical trials for our products, and those third parties may not perform satisfactorily.

     We do not have the ability to independently conduct clinical studies, and we rely on third parties to perform this function. If these third parties do not perform satisfactorily, we may not be able to locate acceptable replacements or enter into favorable agreements with them, if at all. If we are unable to rely on clinical data collected by others, we could be required to repeat, extend the duration of, or increase the size of, clinical trials, which could significantly delay commercialization and require significantly greater expenditures.

If we are unable to develop new products, our expenses may continue to exceed our revenue indefinitely, without any return on the investment.

Table of Contents

     We currently have a variety of new products in various stages of research and development and are working on possible improvements, extensions and reformulations of some existing products. These research and development activities, as well as the clinical testing and regulatory approval process, which must be completed before commercial quantities of these developments can be sold, will require significant commitments of personnel and financial resources. Delays in the research, development, testing or approval processes will cause a corresponding delay in revenue generation from those products. Regardless of whether they are ever released to the market, the expense of such processes will have already been incurred.

     We re-evaluate our research and development efforts regularly to assess whether our efforts to develop a particular product or technology are progressing at a rate that justifies our continued expenditures. On the basis of these re-evaluations, we have abandoned in the past, and may abandon in the future, our efforts on a particular product or technology. Products we are researching or developing may never be successfully released to the market. If we fail to take a product or technology from the development stage to market on a timely basis, we may incur significant expenses without a near-term financial return.

If we do not successfully integrate new products into our business, we may not be able to sustain revenue growth and we may not be able to compete effectively.

     When we acquire or develop new products and product lines, we must be able to integrate those products and product lines into our systems for marketing, sales and distribution. If these products or product lines are not integrated successfully, the potential for growth is limited. The new products we acquire or develop could have channels of distribution, competition, price limitations or marketing acceptance different from our current products. As a result, we do not know whether we will be able to compete effectively and obtain market acceptance in any new product categories. A new product may require us to significantly increase our sales force and incur additional marketing, distribution and other operational expenses. These additional expenses could negatively affect our gross margins and operating results. In addition, many of these expenses could be incurred prior to the actual distribution of new products. Because of this timing, if the new products are not accepted by the market, or if they are not competitive with similar products distributed by others, the ultimate success of the acquisition or development could be substantially diminished.

We rely on the services of a single company to distribute our products to our customers.

     All of our product distribution activities are handled by SPS. SPS stores and distributes our products from a warehouse in Tennessee. Any delay or interruption in the process or in payment could result in a delay delivering product to our customers, which could have a material effect on our business.

Our sales depend on payment and reimbursement from third party payors, and if they reduce or refuse payment or reimbursement, the use and sales of our products will suffer, we may not increase our market share, and our revenues and profitability will suffer.

     Our products’ commercial success is dependent, in part, on whether third-party reimbursement is available for the use of our products by hospitals, clinics, doctors and patients. Third-party payors include state and federal governments, under programs such as Medicare and Medicaid, managed care organizations, private insurance plans and health maintenance organizations. Over 70% of the U.S. population now participates in some version of managed care. Because of the size of the patient population covered by managed care organizations, it is important to our business that we market our products to them and to the pharmacy benefit managers that serve many of these organizations. Payment or reimbursement of only a portion of the cost of our prescription products could make our products less attractive, from a net-cost perspective, to patients, suppliers and prescribing physicians. Managed care organizations and other third-party payors try to negotiate the pricing of medical services and products to control their costs. Managed care organizations and pharmacy benefit managers typically develop formularies to reduce their cost for medications. Formularies can be based on the prices and therapeutic benefits of the available products. Due to their lower costs, generics are often favored. The breadth of the products covered by formularies varies considerably from one managed care organization to another, and many formularies include alternative and competitive products for treatment of particular medical conditions. Exclusion of a product from a formulary can lead to its sharply reduced usage in the managed care organization patient population. If our products are not

20

Table of Contents

included within an adequate number of formularies or adequate reimbursement levels are not provided, or if those policies increasingly favor generic products, our market share and gross margins could be negatively affected, as could our overall business and financial condition.

     In 2002, we expanded our contracts with managed care organizations in an effort to increase the inclusion of our products on formularies and reduce the co-payments required to be made by the ultimate consumer. To the extent that our products are purchased by patients through a managed care group with which we have a contract, our average selling price is lower than it would be for a non-contracted managed care group. We take reserves for the estimated amounts of rebates we will pay to managed care organizations each quarter. Any increase in returns and any increased usage of our products through Medicaid or managed care programs will affect the amount of rebates that we owe.

Risks Related To Our Industry

We face intense competition, which may limit our commercial opportunities and our ability to become profitable.

     The specialty pharmaceutical industry is highly competitive. Competition in our industry occurs on a variety of fronts, including developing and bringing new products to market before others, developing new technologies to improve existing products, developing new products to provide the same benefits as existing products at less cost and developing new products to provide benefits superior to those of existing products.

     Most of our competitors are large, well-established companies in the fields of pharmaceuticals and health care. Many of these companies have substantially greater financial, technical and human resources than we have to devote to marketing, sales, research and development and acquisitions. Some of these competitors have more collective experience than we do in undertaking preclinical testing and human clinical trials of new pharmaceutical products and obtaining regulatory approvals for therapeutic products. As a result, they have a greater ability to undertake more extensive research and development, marketing and pricing policy programs. Our competitors may develop new or improved products to treat the same conditions as our products treat or make technological advances reducing their cost of production so that they may engage in price competition through aggressive pricing policies to secure a greater market share to our detriment. Our commercial opportunities will be reduced or eliminated if our competitors develop and market products that are more effective, have fewer or less severe adverse side effects or are less expensive than our products. These competitors also may develop products that make our current or future products obsolete. Any of these events could have a significant negative impact on our business and financial results, including reductions in our market share and gross margins.

     Our products compete with generic pharmaceuticals, which claim to offer equivalent benefit at a lower cost. In some cases, insurers and other health care payment organizations encourage the use of these less expensive generic brands through their prescription benefits coverage and reimbursement policies. These organizations may make the generic alternative more attractive to the patient by providing different amounts of reimbursement so that the net cost of the generic product to the patient is less than the net cost of our prescription brand product. Aggressive pricing policies by our generic product competitors and the prescription benefits policies of insurers could cause us to lose market share or force us to reduce our margins in response.

The growth of managed care organizations and other third-party reimbursement policies may have an adverse effect on our pricing policies and our margins.

     If managed care organizations or other third-party payors do not provide adequate reimbursement levels for our products, or if those reimbursement policies predominantly favor the use of generic products, our sales could decline and our business could be seriously harmed. Managed care initiatives to control costs have influenced primary-care physicians to refer fewer patients to specialists such as dermatologists. Further reductions in these referrals could have a material adverse effect on the size of our potential market as well as our business, financial condition and results of operation.

     Furthermore, federal and state regulations govern or influence the reimbursement to health care providers of fees in connection with medical treatment of certain patients. In the U.S., there have been, and we expect there will continue to be, a number of state and federal proposals that could limit the amount that state or federal

21

Table of Contents

governments will pay to reimburse the cost of drugs. Continued significant changes in the health care system could have a material adverse effect on our business. In addition, we believe the increasing emphasis on managed care in the U.S. will continue to put pressure on the price and usage of our products, which may in turn adversely impact product sales. Further, when a new therapeutic product is approved, the availability of governmental and/or private reimbursement for that product is uncertain, as is the amount for which that product will be reimbursed. We cannot predict the availability or amount of reimbursement for our products or product candidates, and current reimbursement policies for existing products may change at any time. Changes in reimbursement policies or health care cost containment initiatives that limit or restrict reimbursement for our products may cause our revenues to decline.

If product liability lawsuits are brought against us, we may incur substantial costs.

     Our industry faces an inherent risk of product liability claims from allegations that our products resulted in adverse effects to the patient or others. These risks exist even with respect to those products that are approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA. Our insurance may not provide adequate coverage against potential product liability claims or losses. We also cannot be certain that our current coverage will continue to be available in the future on reasonable terms, if at all. Even if we are ultimately successful in product liability litigation, the litigation would consume substantial amounts of our financial and managerial resources, and might create adverse publicity, all of which would impair our ability to generate sales. If we were found liable for any product liability claims in excess of our coverage or outside of our coverage, the cost and expense of such liability could severely damage our business, financial condition and profitability.

Risks Related To Our Stock

Our stock price is volatile and the value of your investment in our stock could decline in value.

     The market prices for securities of specialty pharmaceutical companies like Connetics have been and are likely to continue to be highly volatile. As a result, investors in these companies often buy at very high prices only to see the price drop substantially a short time later, resulting in an extreme drop in value in the stock holdings of these investors. In the past two fiscal years, the price of our common stock has ranged from a low of $4.06 per share to a high of $14.55 per share. In addition, the volatility could result in securities class action litigation. Any litigation would likely result in substantial costs, and divert our management’s attention and resources.

Our charter documents and Delaware law contain provisions that could delay or prevent a change in control, even if the change in control would be beneficial to our stockholders.

     Our certificate of incorporation authorizes our board of directors to issue undesignated preferred stock and to determine the rights, preferences, privileges and restrictions of the preferred stock without further vote or action by our stockholders. The issuance of preferred stock could make it more difficult for third parties to acquire a majority of our outstanding voting stock. We also have a stockholder rights plan, which entitles existing stockholders to rights, including the right to purchase shares of preferred stock, in the event of an acquisition of 15% or more of our outstanding common stock, or an unsolicited tender offer for such shares. We have also entered into “change in control” agreements with our directors, officers, and key employees. Those change in control agreements provide for severance payments to be made in the event of a change in control of the company. Provisions of Delaware law, our rights plan, our charter documents, and other arrangements, including a provision eliminating the ability of stockholders to take actions by written consent, could delay or make difficult the removal of our current management or a merger, tender offer or proxy contest involving us. Further, our stock option and purchase plans generally provide for the assumption of such plans or substitution of an equivalent option of a successor corporation or, alternatively, at the discretion of the board of directors, exercise of some or all of the option stock, including non-vested shares, or acceleration of vesting of shares issued pursuant to stock grants, upon a change of control or similar event.

     The following discussion should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements filed with this Report.

OVERVIEW

     Our commercial business is focused on the dermatology marketplace, which is characterized by a large patient population that is served by relatively small, and therefore more accessible, groups of treating physicians. We currently market two pharmaceutical products, OLUX and Luxíq. Both products have clinically proven therapeutic advantages and we are providing quality customer service to physicians through our experienced sales and marketing professionals. In December 2002, we received approval from the FDA to sell OLUX for the treatment of non-scalp psoriasis.

     In addition to revenue from product sales, we receive royalties on sales of RID and Actimmune in the U.S., and internationally on sales of Banlice, Milice, Bettamousse, and on a super-concentrated aerosol spray licensed worldwide. We are also entitled to receive royalties on future sales of Ridaura. We have licenses with Novartis and with Pharmacia, which have the potential to bear royalties in the future depending on approval of their products for sale.

     In April 2001, we completed the acquisition of Connetics Australia for approximately $16.9 million. We accounted for this transaction using the purchase method and allocated $1.1 million of the purchase price to in-process research and development, based on an independent valuation, and the balance to the tangible assets of Connetics Australia, existing technology and goodwill. In April 2001 we sold our rights to Ridaura, including inventory, to Prometheus for $9.0 million in cash plus a royalty on annual sales in excess of $4.0 million for five years, resulting in a gain of $8.0 million in 2001.

     In addition to our commercial business, we own the rights to a recombinant form of a natural hormone called relaxin. On May 23, 2001, we announced our decision to reduce our investment in the development of relaxin and to search for licensing opportunities or other strategic alternatives for the product. We eliminated 27 employee positions related to relaxin. In 2001, we recorded a $1.1 million charge representing estimated costs accrued in connection with the reduction in workforce and the wind down of relaxin development contracts. In the second quarter of 2002, we recorded an additional charge of $312,000 representing the final payment due under the agreement with Boehringer Ingelheim.

CRITICAL ACCOUNTING POLICIES

     The fundamental objective of financial reporting is to provide useful information that allows a reader to comprehend our business activities. To aid in that understanding, we have identified our “critical accounting policies” which are used in preparing the consolidated financial statements. These policies have the potential to have a more significant impact on our financial statements, either because of the significance of the financial statement item to which they relate, or because they require us to make estimates and judgments due to the uncertainty involved in measuring, at a specific point in time, events that are continuous in nature.

     Revenue Recognition. We record contract revenue for research and development as it is earned based on the performance requirements of the contract. We recognize royalty revenue in the quarter in which the royalty payment is either received from the licensee or may be reasonably estimated, which is typically one quarter following the related sale by the licensee. We recognize non-refundable contract fees for which no further performance obligations exist, and for which we have no continuing involvement, on the earlier of when the payments are received or when collection is assured. Commencing January 1, 2000, we recognize revenue from non-refundable upfront license fees ratably over the period in which we have continuing development obligations when, at the time the agreement is executed, there remains significant risk due to the incomplete state of the product’s development. Revenue associated with substantial “at risk” performance milestones, as defined in the respective agreements, is recognized based upon the achievement of the milestones. We recognize revenue under R&D cost reimbursement contracts as the related costs are incurred.

Table of Contents

     Returns, Rebates and Chargebacks Reserves. We recognize product revenue net of allowances for estimated returns, rebates and chargebacks. We are obligated to accept from customers the return of pharmaceuticals that have reached their expiration date. As part of our revenue recognition policy, we estimate future product returns, rebates and chargeback payments. These estimates determine our revenue reserves. We make these estimates based primarily on our past return, rebate and chargeback experience. We also consider the volume and price mix of products in the retail channel, trends in distributor inventory, economic trends that might impact patient demand for our products (including competitive environment), the economic value of the rebates being offered and other factors. In the past, actual returns, rebates and chargebacks have not generally exceeded our reserves. However, actual returns, rebates and chargebacks in the future period are inherently uncertain. Any changes in our Medicaid liability, any increase in returns, as well as increased usage of our products through managed care programs, will affect the amount of rebates that we owe. If we changed our assumptions and estimates, our revenue reserves would change, which would impact the net revenue we report. In addition, if actual returns, rebates and chargebacks are significantly greater than the reserves we have established, the actual results would decrease our reported revenue. Conversely, if actual returns, rebates and chargebacks are significantly less than our reserves, this would increase our reported revenue.

     Goodwill, Purchased Intangibles and Other Long-Lived Assets — Impairment Assessments. We make judgments about the recoverability of goodwill, purchased intangible assets and other long-lived assets whenever events or changes in circumstances indicate an other than temporary impairment in the remaining value of the assets recorded on our balance sheet. To judge the fair value of long-lived assets, we make various assumptions about the value of the business that the asset relates to and typically estimate future cash flows to be generated by the asset or, in the case of goodwill, the enterprise. This may include assumptions about future prospects for the asset and typically involves computation of the estimated future cash flows to be generated. Based on these judgments and assumptions, we determine whether we need to take an impairment charge to reduce the value of the asset stated on our balance sheet to reflect its actual fair value. Judgments and assumptions about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors such as changes in our business strategy and our internal forecasts. Although we believe the judgments and assumptions we have made in the past have been reasonable and appropriate, different judgments and assumptions could materially impact our reported financial results. More conservative assumptions of the anticipated future benefits from these assets would result in greater impairment charges, which would decrease net income and result in lower asset values on our balance sheet. Conversely, less conservative assumptions would result in smaller impairment charges and higher asset values. For more details about how we make these judgments, see Note 2 in our Notes to Consolidated Financial Statements.

RESULTS OF OPERATIONS

Revenues

Table of Contents

     Our product revenues were $47.6 million in 2002 compared to $30.9 million in 2001 and $20.1 million in 2000. We recognize product revenue net of allowances for estimated returns, rebates and chargebacks. The increase in total product revenue in 2002 was due to continued sales growth of OLUX and Luxíq. This increase was the result of volume and price increases, partially offset by increases in our revenue allowances. The increase in total product revenue in 2001 over 2000 was due to sales growth of Luxíq, and to our first full year of sales of OLUX, which we launched in November 2000. We also recognized product revenue on sales of Ridaura until the April 2001 sale of that product line to Prometheus. Effective April 1, 2000, in connection with our agreement with InterMune, we sold our remaining Actimmune product rights. When we acquired Connetics Australia in April 2001, we began to recognize product revenue on some over-the-counter products they sell and royalty revenue in association with royalty bearing contracts to which Connetics Australia is a party.

     License, contract, royalty and other revenues were $5.2 million in 2002 compared to $3.1 million in 2001 and $20.7 million in 2000. The increase in royalty revenue from 2001 to 2002 was primarily related to increased sales of an aerosol spray product that we have licensed to a third party. The increase in license revenue in 2002 from 2001 was partially due to revenue recognized in association with an agreement we entered into in December 2001 with Pharmacia Corporation and an expanded license agreement with Novartis.

     The agreement with Pharmacia granted Pharmacia exclusive global rights, excluding Japan, to our proprietary foam drug-delivery technology for use in Pharmacia’s Rogaine hair loss treatment. We recognized $1.0 million under the Pharmacia agreement in 2002. The agreement with Novartis expanded the existing global license to Novartis consumer health to cover Liquipatch drug-delivery system for use in topical antifungal applications. Novartis will continue to be responsible for all product development cost, and pay us license fees, milestone payments and royalties on future product sales. We recognized $580,000 of revenue related to this agreement in the quarter ended March 31, 2002.

     The decrease in license revenue in 2001 from 2000 was in part due to our decision in May 2001 to reduce our investment in the development of relaxin. Through the end of 2002, we had not entered into any new licensing opportunities or other strategic alternatives for relaxin. Effective April 1, 2000 we assigned to InterMune our remaining rights and obligations under a license with Genentech for Actimmune and the corresponding supply agreement. In exchange, InterMune paid us approximately $5.2 million in 2000. InterMune paid an additional $942,000 by the end of March 2001, which was offset by related product rebates and chargebacks of $171,000. In August 2002, we entered into an agreement with InterMune to terminate our exclusive option for certain rights in the dermatology field in exchange for an up-front, non-refundable payment of $350,000. We recognized the full amount of this revenue in 2002.

     We anticipate that product revenue will increase in 2003 due to continued sales growth of OLUX and Luxíq. We also anticipate that license and contract revenue will decrease, as several revenue streams from 2002 will not recur in 2003, while royalty revenue is expected to remain about the same in 2003. Beyond 2003, we expect license revenue to fluctuate significantly depending on whether we enter into additional collaborations, when and whether we or our partners achieve milestones under existing agreements, and the timing of any new business opportunities that we may identify.

Cost of Product Revenues

     Our cost of product revenues includes the third party costs of manufacturing OLUX, Luxíq, Ridaura (until April 2001), and Actimmune (until April 2000), royalty payments based on a percentage of our product revenues and product freight and distribution costs from SPS, the third party that handles all of our product distribution activities. We recorded cost of product revenues of $4.2 million in 2002 compared to $3.1 million in 2001 and $3.9 million in 2000. The increase in total cost of product revenues in 2002 was the result of an increase in sales volumes. On a percentage basis, cost of product revenues decreased to 8.8% in 2002 from 10.1% in 2001. When we acquired Connetics Australia, we began to eliminate all intercompany transactions in consolidation, which included our royalty expense and Connetics Australia’s related royalty income. The decrease in cost of product revenues from 2001 to 2002 on a percentage basis was primarily due to the elimination of intercompany royalties, partially offset by an increase in the cost per unit of our products. The decrease in cost of product revenues from 2000 to 2001 was primarily due to the elimination of intercompany royalties, as well as a change in product mix as a result of discontinuing sales of Ridaura, which had higher manufacturing costs than our other products. We sold the rights to Ridaura to Prometheus in April 2001.

30

Table of Contents

We anticipate a slight increase in the cost of product revenues in 2003, on a per unit basis as we shift the production of our products to domestic suppliers.

Research and Development

     Research and development expenses include costs of personnel to support our research and development activities, costs of preclinical studies, costs of conducting our clinical trials, such as clinical investigator fees, monitoring costs, data management and drug supply costs, external research programs, and an allocation of facilities costs, salaries and benefits, and overhead costs such as rent, supplies and utilities. Research and development expenses increased in 2002 to $25.8 million, compared to $19.2 million in 2001 and $21.9 million in 2000.

In 2002, our research and development expenses primarily consisted of:

	•		$7.4 million on preclinical and clinical research in the development of new dermatology products,
	•		$5.1 million on quality assurance and quality control in the enhancement of existing dermatology products,
	•		$3.9 million on the optimization of manufacturing and process development for existing dermatology products,
	•		$2.7 million on manufacturing, process development and optimization of dermatology products under development,
	•		$1.9 million on quality assurance and quality control in the development of new dermatology products,
	•		$1.3 million on basic research and formulation of new dermatology products, and
	•		$1.1 million on the regulatory review of new and existing dermatology products.

In 2001, our research and development expenses primarily consisted of:

	•		$6.1 million on new dermatology product efforts,
	•		$4.9 million on relaxin development efforts prior to the May 2001 decision to reduce investment in the program,
	•		$7.6 million on development efforts to expand the usage of existing dermatology products, and
	•		$0.6 million to integrate Connetics Australia into our research and development efforts from April 2001.

In 2000, our research and development expenses primarily consisted of:

	•		$10.8 million toward the manufacturing scale-up of relaxin,
	•		$6.3 million for conducting a Phase II/III trial of relaxin for the treatment of scleroderma,
	•		$1.8 million for increased personnel in our organization, and
	•		$1.8 million in expenses associated with the initiation of clinical trials of relaxin.

Table of Contents

     We are currently conducting research on a number of potential therapeutic products for new indications that are in various phases of clinical and pre-clinical development. Pharmaceutical research and development programs, by their nature, require a substantial amount of financial and human resources and the FDA may not approve our product candidates for marketing. The costs to develop all of our potential drugs through all clinical phases would cost substantially more than the funds currently available to us. We are unable to predict the level of spending until near the end of the various programs because of the uncertainty of FDA approval of clinical study programs. We caution that many of our development efforts could experience delays, setbacks and failures, with no assurance that any of our clinical research will reach the stage of an NDA or that the NDA will be approved.

     The following table sets forth the status of, and costs attributable to, our current research and clinical development programs. The actual timing of completion of those phases could differ materially from the estimates provided in the table. For a discussion of the risks and uncertainties associated with the timing of completing a product development phase, see the discussion of clinical risks set forth in “Factors Affecting Our Business and Prospects.” Clinical development is inherently uncertain and expense levels may fluctuate unexpectedly because we cannot accurately predict the timing and level of such expenses.

     Pharmaceutical products that we develop internally can take several years to research, develop and bring to market in the United States. We cannot reliably estimate the overall completion dates or total costs to complete our major research and development programs. The clinical development portion of these programs can span several years and any estimation of completion dates or costs to complete would be highly speculative and subjective due to the numerous risks and uncertainties associated with developing pharmaceutical products. The FDA defines the steps required to develop a drug in the U.S. Clinical development typically involves three phases of study, and the most significant costs associated with clinical development are the Phase III trials as they tend to be the longest and largest studies conducted during the drug development process. The lengthy process of seeking these approvals, and the subsequent compliance with applicable statutes and regulations, require the expenditure of substantial resources. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could materially adversely affect our business. For additional discussion of the risks and uncertainties associated with completing development of potential products, see “Factors Affecting Our Business and Prospects — We cannot sell our current products and product candidates if we do not obtain and maintain governmental approvals” and “—We may spend a significant amount of money to obtain FDA and other regulatory approvals, which may never be granted” and “— If we are unable to develop new products, our expenses may continue to exceed our revenue indefinitely, without any return on the investment.”

Selling, General and Administrative Expenses

     Selling, general and administrative expenses were $37.6 million in 2002, $36.1 million in 2001, and $26.7 million in 2000. The increase in 2002 over 2001 was primarily due to:

32

Table of Contents

	•		$1.3 million increase compared to 2001 related to the introduction of product samples,
	•		$2.7 million increase compared to 2001 in labor and benefit expenses due to increased head count as well as having a full year of expanded sales force compared to eight months in 2001, and
	•		an increase compared to 2001 in depreciation expenses related to equipment purchased to support increased headcount, as well as a full year of depreciation related to equipment supporting the expanded sales force,
	•		partially offset by $2.6 million in non-cash stock compensation expense in 2001 that did not recur in 2002.

The increase in 2001 over 2000 was primarily due to:

	•		the addition of 32 employees in our sales and marketing organizations,
	•		additional market research and sales costs related to the OLUX launch and the launch of OLUX and Luxíq 50 gram units,
	•		$1.1 million for the amortization of intangibles associated with the acquisition of Connetics Australia in 2001, and
	•		$2.6 million in non-cash stock compensation charges.

We expect selling, general and administrative expenses to remain consistent or be slightly higher in 2003 due to the commencement of marketing efforts relating to the anticipated outcome of clinical trials for antifungal foam and anti-acne foam.

Acquired In-Process Research and Development

     In May 2002, we entered into an agreement with Yamanouchi Europe B.V. to license Velac® gel (a first in class combination of 1% clindamycin, and 0.025% tretinoin). We have licensed exclusive rights to develop and commercialize the product in the U.S. and Canada, and have licensed non-exclusive rights in Mexico. Under the terms of the agreement, we paid Yamanouchi an initial $2.0 million licensing fee, which we recorded as acquired in-process research and development expense during the quarter ended June 30, 2002, because the product remains in clinical development and has no alternative future use. In the fourth quarter of 2002, we initiated a Phase III trial for Velac. Under the terms of the agreement, we recorded an additional $2.0 million of acquired in-process research and development expense related to this milestone.

     In April 2001, we completed the acquisition of Connetics Australia (then known as Soltec) for approximately $16.9 million. We accounted for this transaction using the purchase method and allocated $1.1 million of the purchase price to acquired in-process research and development, based on an independent valuation, and the balance to the tangible assets of Connetics Australia, existing developed technology and goodwill. Acquired in-process research and development consisted of several projects, which involved the use of novel technologies to improve the delivery of drugs. The projects were and still are in various stages of development and are subject to substantial risks, and did not have alternative future uses. The value of the in-process research and development was determined by an independent valuation expert using a discounted cash flow analysis with a rate of 20%. In addition, the stage of completion of each project was considered in determining the value.

     These projects may not meet either technological or commercial success. The products under development have no foreseeable alternative future uses. The estimates we used in valuing in-process research and development were based on assumptions we believe to be reasonable, but they are inherently uncertain and unpredictable. Our assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur. Accordingly, actual results may vary from the results projected for purposes of determining the fair value of the acquired in-process research and development.

Loss on program termination (relaxin)

     In the second quarter of 2001 we recorded a $6.0 million charge representing estimated costs accrued in connection with the reduction in workforce and the wind down of relaxin development contracts. In the fourth quarter of 2001 we reversed $4.9 million of this charge due to the settlement of potential amounts owed. In the second quarter of 2002 we recorded an additional charge of $312,000, representing the final payment due under an agreement with Boehringer Ingelheim. For additional information, see Note 10 in our Notes to Consolidated Financial Statements for a discussion of the relationship with Boehringer Ingelheim.

Interest and other income (expense), net

     Interest income was $823,000 for 2002, compared to $2.5 million for 2001 and $2.1 million for 2000. The decrease in interest income in 2002 from 2001 was the result of lower cash and investment balances, combined with a decrease in market interest rates on investments. The increase in interest income in 2001 over 2000 arose from the high cash and investment balance which arose from the sale of InterMune shares in December 2000.

     Interest expense was $11,000 in 2002, compared to $46,000 in 2001 and $235,000 in 2000. Interest expense in 2002 was primarily related to a financing arrangement associated with our corporate insurance policies. There were no capital leases outstanding during 2002. The decrease in interest expense in 2001 over 2000 resulted from lower interest expense associated with lower balances outstanding for obligations under capital leases, and long term debt.

     Other income (expense) was a net income of $227,000 in 2002 compared to a net expense of $519,000 in 2001 and zero in 2000. The net other income in 2002 was directly related to the rents received from two sublease arrangements. The net other expense in 2001 was primarily due to a $555,000 net loss on a foreign exchange forward contract partially offset by rents received from a sublease arrangement. The contract was entered into in relation to a business combination and does not qualify as a hedge under SFAS 133. The purpose of the contract was to lock in the purchase price paid for Connetics Australia. The foreign exchange forward contract was terminated on the closing date of the acquisition of Connetics Australia.

Income Taxes

     Income tax expense was $181,000 in 2002 compared to $345,000 in 2001 and $1.0 million in 2000. Income tax expense for 2002 reflects $798,000 of foreign tax provision recorded by Connetics Australia, substantially offset by a U.S. tax benefit of $617,000. The U.S. tax benefit arose principally because of the provisions of the Job Creation and Worker Assistance Act of 2002 enacted on March 9, 2002, which allows taxpayers to carry back net operating losses generated in 2001 and 2002 to offset alternative minimum tax previously paid. Income tax expense in 2001 arose from the taxable operating results of Connetics Australia. The income tax provision for 2000 consisted of alternative minimum tax paid as a result of a $43.0 million gain from the sale of securities. For a more complete description of our income tax position, refer to Note 13 in our Notes to Consolidated Financial Statements.

Change in Accounting Principle

     Effective January 1, 2000, we changed our method of accounting for nonrefundable up-front license fees to recognize such fees over the expected research and development period. The $5.2 million cumulative effect of the change in accounting principle, calculated as of January 1, 2000, was reported as a charge in the year ended December 31, 2000. The cumulative effect was initially recorded as deferred revenue and is being recognized as revenue over the research and development period of the agreements. During the year ended December 31, 2000, the impact of this change in accounting method (excluding the cumulative effect itself) increased net income by $4.4 million or $0.15 per share. This increase consists of $4.9 million revenue deferred in the cumulative effect that was recognized as income in 2000 under the new accounting method, offset by the impact of deferring upfront fees received in 2000. During 2000, approximately $4.1 million of revenue deferred as a component of the cumulative effect charge was fully recognized in the fourth quarter when two of our collaboration partners terminated their agreements with us as a result of the failure of relaxin to meet the primary endpoint in a Phase III trial, and we were released from further obligations. Revenue for both 2002 and 2001 includes $132,000 of revenue previously

34

Table of Contents

recognized and included in the cumulative effect adjustment. The unamortized balance of deferred revenue at December 31, 2002, of approximately $527,000 is expected to be recognized as revenue of approximately $132,000 per year during the years ending 2003 through 2006. The pro forma amounts presented in the statement of operations were calculated assuming the accounting change had been in effect for prior periods, and was made retroactive to prior periods.

LIQUIDITY AND CAPITAL RESOURCES

     Sources and Use of Cash. We have financed our operations to date primarily through proceeds from equity financings, sale of investments, collaborative arrangements with corporate partners, bank loans, and product revenues. At December 31, 2002, cash, cash equivalents and short-term investments totaled $33.1 million, compared to $46.3 million at December 31, 2001 and $79.9 million at December 31, 2000. Accounts receivable, net, totaled $4.3 million at December 31, 2002, compared to $5.4 million at December 31, 2001. Our cash balances are held in a variety of interest-bearing instruments including high-grade corporate bonds, commercial paper and money market accounts.

     Cash Flows from Operating Activities. Cash used in operations was $12.5 million for 2002 compared to $24.6 million for 2001 and $15.3 million in 2000. Net loss of $16.6 million for 2002 was affected by non-cash charges of $2.1 million of depreciation and amortization expense and a $2.1 million gain on the sale of investments. Cash usage was partially offset by a decrease in accounts receivable of approximately $1.1 million related to timing of sales and collection of outstanding amounts, and an increase in accounts payable of approximately $4.1 million related to increased development costs.

     Net loss of $16.7 million for 2001 was affected by non-cash charges of $2.0 million of depreciation and amortization expense and $555,000 in other expense related to the foreign exchange forward contract, acquired in-process research and development charge of $1.1 million related to the Connetics Australia acquisition, a one-time $1.1 million charge related to the reduction in the relaxin program, and non-cash compensation charges in the amount of $2.6 million, more than offset by the $8.0 million gain on the sale of the Ridaura product line. The primary reason for the decrease in operating cash flows in 2001 was that we had a $122,000 gain on the sale of InterMune stock in 2001 compared to a $43.0 million gain in 2000 and an unfavorable change in working capital accounts in 2001 of approximately $5.9 million.

     Net income of $27.0 million for 2000 was affected by the gain on sale of InterMune stock of $43.0 million, partially offset by non-cash charges of $764,000 of depreciation and amortization expense and $1.0 million non-cash compensation expense.

     Cash Flows from Investing Activities. Investing activities provided $10.9 million in cash during 2002 compared to cash used in investing activities of $29.9 million in cash during 2001 and $44.2 million provided by investing activities in 2000. The principal source of cash from investing activities in 2002 was net sales of short-term investments, which was partially offset by the use of cash to construct an aerosol filling line at DPT’s plant in Texas. The principal uses of cash for investing activities in 2001 were net purchases of short-term investments and the acquisition of Connetics Australia, which were partially offset by proceeds from the sale of the Ridaura product line.

     Cash Flows from Financing Activities. Financing activities provided $6.5 million in cash during 2002 compared to cash used in financing activities of $200,000 in 2001 and to cash provided by financing activities of $21.0 million in 2000. The principal sources of cash from financing activities in 2002 were proceeds from the sale of common stock of $5.1 million pursuant to the exercise of warrants and stock options and the $1.4 million reduction of restricted cash in connection with the requirements of an operating lease arrangement and collateral on various officer loans.

     Working Capital Working capital decreased to $25.2 million at December 31, 2002 from $44.0 million at December 31, 2001. Our working capital primarily decreased as we used cash in operations and for the purchase of acquired in-process research and development. Working capital decreased to $44.0 million at December 31, 2001

35

Table of Contents

from $71.0 million at December 31, 2000. Our working capital primarily decreased as we used cash in operations and acquired Connetics Australia. The decrease was partially offset by the sale of the Ridaura product line.

     Contractual Obligations and Commercial Commitments. As of December 31, 2002, we had the following contractual obligations and commitments:

	(1)		We lease laboratory and office facilities under noncancelable operating leases, which expire through 2005. In March 2002 we entered into an agreement with DPT to construct an aerosol filling line at DPT’s plant in Texas. Under the agreement we are obligated to pay approximately $56,000 per year in rent, for an indefinite period of time, for the pro rata portion of DPT’s facility allocated to the aerosol line. We also lease various automobiles and office equipment under similar leases, expiring through 2006. These obligations are to be partially offset by $458,000 to be received from subleasing arrangements with third parties.
	(2)		In 2002 we entered into short term financing arrangements related to our corporate insurance policies. All remaining amounts related to these financing arrangements will be paid in 2003 and have been included in Other Accrued Liabilities on the Consolidated Balance Sheet.
	(3)		In March 2002 we entered into a manufacturing and supply agreement with DPT that requires minimum purchase commitments, beginning six months after the opening of the commercial production line and continuing for 10 years. Also in 2002 we entered into a license agreement that requires minimum royalty payments beginning in 2005 and continuing for fifteen years.

As of December 31, 2002, we had no off-balance sheet financing arrangements or commitments other than those disclosed in the table above.

     Restricted Cash and Cash Equivalents. As of December 31, 2002, $724,000 of our total cash and cash equivalents balance was restricted cash, held in various certificates of deposit, for specific purposes: $111,000 relates to collateral on a personal bank loan to one of our officers, and $613,000 relates to a deposit required in connection with a noncancelable operating lease.

     We believe our existing cash, cash equivalents and short-term investments, cash generated from product sales and collaborative arrangements with corporate partners, will be sufficient to fund our operating expenses, debt obligations and capital requirements through at least the next 12 months. Future revenues from sales are uncertain as we are subject to patent risks and competition from new products, and products under development may not be safe and effective or approved by the FDA, or we may not be able to produce them in commercial quantities at reasonable costs, and the products may not gain satisfactory market acceptance. Our future capital uses and requirements will depend on numerous factors, including the progress of our research and development programs, the progress of clinical testing, the time and costs involved in obtaining regulatory approvals, the cost of filing, prosecuting, and enforcing patent claims and other intellectual property rights, competing technological and market developments, the level of product revenues, and the possible acquisition of new products and technologies. A key element of our strategy is to in-license or acquire additional marketed or late-stage development products. A portion of the funds needed to acquire, develop and market any new products may come from our existing cash, which will result in fewer resources available to our current products and clinical programs. We are currently evaluating a number of business development opportunities, including the possibility of acquiring or in-licensing other products. If we successfully reach agreements with third parties, these transactions may require us to use some of our available cash, or to raise additional cash by liquidating some of our investment portfolio and/or raising additional funds through equity or debt financings in connection with the transaction.

     We currently have no commitments for any additional financings. If we need to raise additional money to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to raise additional funds when needed, we may not be able to market our products as planned or continue development of our other products, or we could be required to delay, scale back or eliminate some or all of our research and development programs.

RECENT ACCOUNTING PRONOUNCEMENTS

     SFAS 146. In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146, “Accounting for Costs Associated with Exit and Disposal Activities” (SFAS 146). This statement revises the accounting for exit and disposal activities under Emerging Issues Task Force Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity.” Specifically, SFAS 146 requires that companies record the costs to exit an activity or dispose of long-lived assets when those costs are incurred. SFAS 146 requires that the measurement of the liability be at fair value. The provisions of SFAS 146 are effective prospectively for exit or disposal activities initiated after December 31, 2002. Upon the adoption of SFAS 146, previously issued financial statements shall not be restated. We will assess the impact of adoption of SFAS 146 based on the nature of transactions ongoing at the adoption date.

     SFAS 148. In December 2002, the FASB issued Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure.” This statement amends SFAS No. 123, “Accounting for Stock-Based Compensation,” to provide alternative methods of transition for an entity that changes to the fair value method of accounting for stock-based employee compensation. In addition, SFAS 148 amends the disclosure provisions of SFAS 123 and APB Opinion No. 28, “Interim Financial Reporting” to require expanded and more prominent disclosure of the effects of an entity’s accounting policy with respect to stock-based employee compensation. SFAS 148 does not amend SFAS 123 to require companies to account for employee stock options using the fair value method. However, the disclosure provisions of SFAS 148 are applicable to all companies with stock-based employee compensation, regardless of whether they account for the compensation using the fair value method of SFAS 123 or the intrinsic value method of APB Opinion No. 25. The provisions of SFAS 148 are effective for fiscal years ending after December 15, 2002. See “Stock-Based Compensation” in Note 2 of our Notes to Consolidated Financial Statements for disclosures required by SFAS 148.

     FIN 45. In November 2002, the FASB issued Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”). FIN 45 requires that upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation it assumes under that guarantee. FIN 45 is effective on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. Our adoption of FIN 45 did not have a material effect on our financial position or results of operations.

     FIN 46. In January 2003, the FASB issued Interpretation 46, “Consolidation of Variable Interest Entities” (“FIN 46”). FIN 46 requires that companies that control another entity through interests other than voting interests should consolidate the controlled entity. FIN 46 applies to variable interest entities created after January 31, 2003, and to variable interest entities in which an enterprise obtains an interest after that date. The consolidation requirements apply to older entities in the first fiscal year or interim period beginning after June 15, 2003. Certain disclosure requirements apply to all financial statements issued after January 31, 2003, regardless of when the variable interest entity was established. The adoption of FIN 46 is not expected to have a significant impact on our financial position or results of operations.

OUR BUSINESS STRATEGY MAY CAUSE FLUCTUATING OPERATING RESULTS

     Our operating results and financial condition may fluctuate from quarter to quarter and year to year depending upon the relative timing of events or uncertainties that may arise. For example, the following events or occurrences could cause fluctuations in our financial performance from period to period:

•

changes in the levels we spend to develop new product lines,

Table of Contents

	•		changes in the amount we spend to promote our products,
	•		changes in treatment practices of physicians that currently prescribe our products,
	•		changes in reimbursement policies of health plans and other similar health insurers,
	•		forward-buying patterns by wholesalers that may result in significant quarterly swings in revenue reporting,
	•		increases in the cost of raw materials used to manufacture our products,
	•		the development of new competitive products by others,
	•		the mix of products that we sell during any time period, and
	•		our responses to price competition.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

     Interest Rate Risk. Our holdings of financial instruments comprise a mix of securities that may include U.S. corporate debt, U.S. government debt, and commercial paper. All such instruments are classified as securities available for sale. The average time to maturity of our investments is 87 days. Generally, we do not invest in portfolio equity securities or commodities or use financial derivatives for trading purposes. Our market risk exposure consists principally of exposure to reductions in interest rates. The table below presents the principal amounts and weighted average interest rates by year of maturity for our investment portfolio as of December 31, 2002 (in thousands):

     Foreign Currency Exchange Risk. Certain payments by third parties to Connetics Australia are made in local currency or Australian dollars, and payments by Connetics Australia to Celltech in the U.K. are made in Australian dollars. Any fluctuations in the currencies of our licensees or licensors against the Australian or the U.S. dollar will cause our royalty revenues and expenses to fluctuate as well. We currently do not hedge our exposure to changes in foreign currency exchange rates. Interest income from our investments is sensitive to changes in the general level of U.S. interest rates, particularly since the majority of our investments are in short-term instruments. Due to the nature of our short-term investments, we have concluded that we face minimal material market risk exposure.

Our disclosure controls and procedures are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based on their evaluation, the CEO and CFO concluded that the company’s disclosure controls and procedures were effective in timely alerting them to material information required to be included in our periodic SEC reports. There have been no significant changes in Connetics’ internal controls or in other factors that could significantly affect internal controls since their evaluation.
