PART I Item 1. BUSINESS INTRODUCTION-FORWARD LOOKING STATEMENTS - --------------------------------------- Except for statements of historical fact, the statements herein are forward- looking and are subject to a number of risks and uncertainties that could cause actual results to differ materially from the statements made. These include, among others, uncertainty associated with timely development, approval, launch and acceptance of new products, establishment of new corporate alliances, progress in research and development programs and other factors described below under the headings "APP Technology", "Products", "Manufacturing", "Marketing", "Government Regulation", "Patents and Trade Secrets" and "Competition". In addition, such risks and uncertainties also include the matters discussed under Management's Discussion and Analysis of Financial Condition and Results of Operations in Item 7 below. COMPANY OVERVIEW - ---------------- In this Annual Report on Form 10-K, the "Company", "A.P. Pharma", "APP", "we", "us", and "our", refer to A.P. Pharma, Inc. We are a specialty pharmaceutical company focused on the development of pharmaceutical products utilizing our proprietary polymer-based drug delivery systems. Our focus is the development and commercialization of bioerodible injectable and implantable systems under the trade name Biochronomer(TM). Our business strategy is twofold: - - to develop selected proprietary products, funding them through the preliminary phases of regulatory review before entering partnerships to share costs and to earn a share of future profits; and - - to license our proprietary technologies to corporate partners after the successful completion of reimbursed feasibility studies to earn research and development fees, licensing fees, milestone payments and royalties. Initial targeted areas of application for our drug delivery technologies include pain management; anti-inflammatory, oncology and ophthalmology applications; device coatings and DNA delivery. Product development programs are primarily funded by royalties from topical prescription products currently marketed by pharmaceutical partners, proceeds from the divestiture of our cosmeceutical product lines in July 2000, fees we receive from collaborative partners, and proceeds from the sale of our Analytical Standards business in February 2003. Bioerodible polymers are of increasing interest within the pharmaceutical and biotechnology community for use in both drug delivery applications and as devices. We have made substantial progress in developing bioerodible polymers that potentially represent a significant improvement over existing drug delivery systems. The major point of difference is that our polymers have been specifically designed as drug delivery systems and are versatile. Erosion times can be varied from hours to days, weeks or months and mechanical properties can be adjusted to produce materials ranging from injectable gels, coatings, to strands, wafers, films or microspheres. In addition, the manufacturing is reproducible, has been scaled up and the polymers are stable at room temperature, provided they are stored under anhydrous conditions. In studies, the polymers were observed to erode to completion and, once the drug was released, no polymer remained. In addition, the polymers bioerode with low acidity, thus potentially allowing the delivery of sensitive proteins and DNA. We filed our first Investigational New Drug Application ("IND") in the fourth quarter of 2001 for our product candidate APF112 for the treatment of post- surgical pain following arthroscopic knee surgery, and completed Phase I human clinical trials in the first half of 2002. In August 2002, we withdrew the proposed protocol for a Phase II clinical study in response to questions raised by the United States Food and Drug Administration ("FDA") regarding the duration of mild-to-moderate irritation observed in preclinical studies. This mild-to-moderate irritation was observed following administration into the knee joint of certain animal species. In December 2002, we announced that we had agreed on an action plan with the FDA that could allow us to initiate Phase II human clinical studies in the middle of 2003. We modified the formulation of APF112 to minimize irritation, and decided to initially target pain management following surgery to repair inguinal hernias. More than 5.3 million abdominal surgeries are performed annually in the United States ("U.S.") and, with the demonstration of efficacy of APF112 in the treatment of post-surgical pain, we believe that there are more than 20 million surgical procedures performed annually in the U.S. for which the product could be utilized. We have also entered into fee-paying feasibility studies with several companies to develop a variety of products using our Biochronomer(TM) delivery systems. These products are being developed in the areas of ophthalmology, device coatings and DNA delivery. In general, these research and development arrangements provide for us to receive research and development fees from our collaborators. Five of these development programs have now moved into in vivo testing and, if they are concluded successfully, could lead to licensing agreements under which a partner would pay for development costs and we would receive a license fee, research and development fees, milestone payments and a royalty upon a product's marketing clearance and commercialization. In February 1997, we received FDA marketing clearance for our first pharmaceutical product based on the original patented Microsponge(R) technology, Retin-A Micro(R), which was licensed to Ortho Neutrogena, a member of the Johnson & Johnson family of companies. This product was launched in the United States in March 1997. Retin-A Micro was also launched in Canada in the third quarter of 2001 and Phase III clinical trials were completed in Europe in 2002. In May 2002, the FDA granted marketing clearance for a new low-dose formulation of Retin-A Micro, which was launched in July 2002. We licensed to Dermik Laboratories, an Aventis company, a Microsponge-based formulation incorporating 5-fluorouracil (5-FU) for the treatment of actinic keratoses, a precancerous skin condition. The product was launched in the first quarter of 2001 under the brand name Carac(TM). This product has a number of advantages over existing topical therapies, including less irritation with shorter duration of therapy and reduced dosage frequency. Until July 2000, we engaged in the development, manufacturing, and out- licensing of the aforementioned topical pharmaceutical products as well as a variety of cosmeceutical and toiletry products. In July 2000, we sold our cosmeceutical and toiletry product lines, together with certain technology rights to topical pharmaceuticals, to RP Scherer, a subsidiary of Cardinal Health. We received $25 million at closing and are entitled to receive further annual earnout amounts for the subsequent three years, the amounts of which are dependent on the performance of the product lines sold. We recorded approximately $3 million at the end of the first earnout period ending June 30, 2001, which represents earnout payments received of $3.6 million less reserves for certain indemnification claims allowable under the sale agreement, and approximately $200,000 for the second earnout period ending June 30,2002. Under the sale agreement, we retained the rights to our topical prescription products, which are marketed by our corporate partners, Johnson & Johnson and Aventis, and on which we continue to receive royalties. In February 2003, we sold the assets of our wholly-owned subsidiary, APS Analytical Standards, Inc., to GFS Chemicals of Columbus, Ohio, for $2.1 million in cash and the right to receive royalties for the next five years. The Company, founded in February 1983 as a California corporation under the name AMCO Polymerics, Inc., changed its name to Advanced Polymer Systems, Inc. in 1984 and was reincorporated in Delaware in 1987. We changed our name to A.P. Pharma, Inc. in May 2001 to reflect the new pharmaceutical focus of the Company. APP TECHNOLOGY - -------------- We have made significant investment and progress in the development of bioerodible drug delivery systems. Specifically, we have developed two families of polymers, each with unique attributes. The first family is known collectively as poly(ortho esters) under the trade name Biochronomer(TM); polymers in the second family are known collectively as block copolymers of poly(ortho esters) and poly(ethylene glycol) under the trade name Bioerodimer(TM). The two polymer families are covered by US patent 5,968,543, issued October 19, 1999 and US patent 5,939,453, issued August 17, 1999. Both are broad composition of matter patents. A number of other patent applications have been filed. Current product development work takes advantage of the versatility of these materials, and is exemplified by forms that range from injectable gels into which drugs can be incorporated by a simple mixing procedure, to solid devices that can be fabricated at temperatures low enough to allow the incorporation of materials such as proteins that require mild fabrication conditions. Our primary focus has been on advancing our Biochronomer technology, which is designed to release drugs at selected implantation sites such as at the site of a surgical procedure, under the skin, in joints, in the eye, or in muscle tissue. Key benefits of this technology include the ability to fabricate the poly(ortho ester) polymers into a variety of drug delivery forms - ranging from wafers and strands to microspheres and injectable gels to enable various means of administration into the body. Also under development are device applications. Because both mechanical properties and erosion rates can be controlled, these polymers are emerging as promising materials for device coatings that could be useful in cardiovascular applications such as stent coatings, and in the development of scaffolding materials used in tissue engineering. The Biochronomer polymer is a poly(ortho ester) that is produced by a condensation reaction between a diketene acetal and a diol, or mixture of diols. This reaction is highly reproducible and kilo quantities of polymer have been produced according to Good Manufacturing Practices (GMP). Approximately one hundred in vivo and in vitro studies have been completed to advance understanding of this innovative drug delivery technology. The data demonstrate that Biochronomer systems have potential in a wide range of applications, including pain management; osteoarthritis; anti-adhesion, anti- inflammatory, anti-infective; ophthalmic diseases, bone growth, device coatings, restenosis and tissue engineering. Importantly, the initial toxicology data indicate that the technology is safe for use in the body. Studies demonstrate complete and controlled bioerosion of the polymers. Furthermore, Biochronomer systems have controlled drug-release rates, both short-term and long-term. Through an academic collaboration, we are also developing water-soluble Bioerodimer polymers with the intent to maximize the concentration of anti- cancer agents in solid tumors and to minimize their concentration in healthy tissue. PRODUCTS - -------- Ethical Pharmaceutical Products - ------------------------------- We define ethical pharmaceutical products as prescription products that are promoted primarily through the medical profession. We are developing several pharmaceutical product candidates that will require marketing clearance from the FDA before they can be sold in the United States. We believe that the benefits offered by our delivery systems will create valuable product differentiation and advantages in large, profitable markets. Results from various preclinical studies reaffirm that this technology offers the potential to reduce drug side effects, maintain or improve therapeutic efficacy and potentially increase patient compliance with a less frequent treatment regimen. The following ethical dermatological products incorporating the Microsponge technology have already been developed and commercialized: Retin-A Micro: In February 1997, we received FDA marketing clearance for Microsponge-entrapped tretinoin for improved acne treatment. Tretinoin has been marketed in the United States by Ortho Neutrogena (formerly Ortho Dermatological), a Johnson & Johnson ("J&J") subsidiary, under the brand name RETIN-A(R) since 1971. It has proven to be a highly effective topical acne medication. However, skin irritation among sensitive individuals can limit patient compliance with the prescribed therapy. We believe this patent- protected approach to drug delivery reduces the potentially irritating side effects of tretinoin. Ortho Dermatological began marketing this product in March 1997 under the brand name Retin-A(R) Micro (TM). We receive royalty income based on the sales of this product over the life of the applicable patents. During 2001, Ortho launched this product in Canada and has now completed Phase III clinical trials in Europe in preparation for a European Union filing. Additionally, Ortho received FDA marketing clearance in the United States for a second Retin-A Micro formulation and launched the product in July of 2002. Carac: In the fourth quarter of 2000, Dermik Laboratories, an Aventis company, received U.S. marketing clearance for an APP-developed formulation containing Microsponge-entrapped 5-fluorouracil (5-FU) for the treatment of actinic keratoses. This product was launched under the trade name Carac(TM) in the first quarter of 2001. We receive royalties based on the sales of this product over the life of the applicable patents. Products Under Development - -------------------------- Our efforts in pharmaceutical markets include additional applications using our Biochronomer technology that are under development, as noted below. The first product candidate that incorporates the Biochronomer(TM) System targets the management of pain in patients following surgery for inguinal hernias. With the demonstration of efficacy in treating post-surgical pain, we believe that there will be substantial potential for this product as there are approximately 20 million surgical procedures performed annually in the U.S. for which the product could potentially be utilized. The treatment strategy is to provide 24 to 36 hours of localized post- surgical pain relief by delivering the drug mepivacaine directly to the surgical site. Mepivacaine is a well-known drug for localized pain relief, and it has an extensive safety protocol. APF112 is designed to minimize the use of opioids (morphine-like drugs) which are currently used in the majority of surgical procedures as a means of managing post-operative pain but with unpleasant side effects - nausea, disorientation, sedation, constipation, vomiting, urinary retention and, in some situations, life-threatening respiratory depression. Other Products - -------------- Analytical Standards. We initially developed microspheres (precursors to the Microsponge system) for use as a testing standard for gauging the purity of municipal drinking water. Marketed nationwide, these microspheres are suspended in pure water to form an accurate, stable, reproducible turbidity standard for the calibration of turbidimeters used to test water purity. We have also developed standards for the calibration of spectrophotometers and colorimeters. In February 2003, we announced the sale of the assets of this subsidiary to GFS Chemicals, Inc. of Columbus, Ohio for $2.1 million in cash and the right to receive royalties for five years at rates ranging from 5% to 15% of sales of analytical standards products. MARKETING - --------- A key part of our business strategy is to form collaborations with pharmaceutical partners. We have therefore negotiated fee-paying feasibility agreements with several pharmaceutical and biotechnology companies for the development of prescription products incorporating the Biochronomer delivery system. In general, we grant limited marketing exclusivity in defined markets for defined periods to our partners. However, after development is completed and a partner commercializes a formulated product utilizing our delivery systems, we can exert only limited influence over the manner and extent of our partner's marketing efforts. Our key marketing relationships currently involving only the Microsponge delivery system for prescription products are as follows: Johnson & Johnson Inc. In May 1992, we entered into a development and license agreement with Ortho-McNeil Pharmaceutical Corporation ("Ortho"), a subsidiary of J&J, related to tretinoin-based products incorporating our Microsponge technology. As part of the agreement, certain license fees and milestone payments were paid to us by Ortho. The license fees provided Ortho with exclusive distribution or license rights for all Ortho tretinoin products utilizing our Microsponge system. Ortho's exclusivity will continue as long as annual minimum royalty payments are made, governed by the life of the applicable patents owned by us. In February 1997, we received FDA marketing clearance for the first product covered by this agreement, Microsponge-entrapped tretinoin. This product has been marketed by Ortho Dermatological since March 1997 as Retin-A(R) Micro. We received a payment of $3,000,000 from Ortho upon receipt of the FDA approval, of which half is a milestone payment that was recognized as revenue in 1997 and half as prepaid royalties which was recorded as deferred revenues. Ortho pays us a royalty on product sales. In accordance with the licensing agreement, 25% of the royalties we earn is applied against deferred revenues after certain annual minimum royalty payments are met. Should these minimums not be achieved, Ortho would lose its exclusivity and we would regain marketing rights to the retinoid products. Dermik. In March 1992, we restructured our 1989 joint venture agreement with Dermik, an Aventis company. As part of the agreement Aventis received certain exclusive marketing rights. Product applications include a 5-FU treatment for actinic keratoses (precancerous skin lesions). In the fourth quarter of 1999, Dermik filed an NDA for this product and expanded its agreement with us to cover two additional indications, in return for milestone payments and royalties upon successful development. We received $500,000 on execution of this amendment representing a milestone payment of $250,000 and prepaid royalties of $250,000. In the fourth quarter of 2000 Dermik received FDA marketing clearance for the product, which was launched under the trade name Carac(TM) in the first quarter of 2001 and we received a milestone payment of $50,000. In 2002, we recognized the prepaid royalties as revenues because Dermik decided not to pursue the two additional applications covered by the 1999 amendment. Dermik's exclusivity will continue as long as annual minimum royalty payments are made, governed by the life of the applicable patents. GOVERNMENT REGULATION - --------------------- Ethical Products - ---------------- In order to clinically test, produce and sell products for human therapeutic use, mandatory procedures and safety evaluations established by the FDA and comparable agencies in foreign countries must be followed. The procedure for seeking and obtaining the required governmental clearances for a new therapeutic product includes preclinical animal testing to determine safety and efficacy, followed by human clinical testing. This can take many years and require substantial expenditures. In the case of third party agreements, we expect that our corporate partners will partially fund the testing and the approval process with guidance from us. We intend to seek the necessary regulatory approvals for our proprietary products as they are being developed. PATENTS AND TRADE SECRETS - ------------------------- As part of our strategy to protect our current products and to provide a foundation for future products, we have filed a number of United States patent applications on inventions relating to specific products, product groups, and processing technology. We have also filed foreign patent applications on our polymer technology with the European Union, Japan, Australia, South Africa, Canada, Korea and Taiwan. We have a total of 11 issued United States patents and an additional 98 issued foreign patents. Currently, we have over 26 pending patent applications worldwide. The patents on the Microsponge(R) system expire between October 2005 and September 2016. The patents on the bioerodible systems expire between January 2016 and November 2021. Although we believe the bases for these patents and patent applications are sound, they are untested, and there is no assurance that they will not be successfully challenged. There can be no assurance that any patent previously issued will be of commercial value, that any patent applications will result in issued patents of commercial value, or that our technology will not be held to infringe patents held by others. We rely on unpatented trade secrets and know-how to protect certain aspects of our production technologies. Our employees, consultants, advisors and corporate partners have entered into confidentiality agreements with us. These agreements, however, may not necessarily provide meaningful protection for our trade secrets or proprietary know-how in the event of unauthorized use or disclosure. In addition, others may obtain access to, or independently develop, these trade secrets or know-how. COMPETITION - ----------- In the development of bioerodible poly(ortho esters) for implantation applications, there is competition from a number of other bioerodible systems, especially polymers based on lactic and glycolic acid and to a lesser extent, polyanhydrides. We believe that our proprietary bioerodible Biochronomer(TM) polymers have a number of important advantages. Among these are ease of manufacturing, ability to control both erosion times and mechanical properties, the simultaneous drug delivery and erosion process, resulting in complete polymer disappearance when all the drug has been delivered. Also, the polymer bioerodes with low acidity, thus potentially allowing the delivery of sensitive proteins and DNA. The attribute of the second family of bioerodible polymers, the block copolymers of poly(ortho esters) and poly(ethylene glycols) is that a hydrophobic (water-repelling) bioerodible segment can be connected to a water-soluble segment. There are other such polymers, but we believe that our proprietary material is superior because the hydrophobic poly(ortho ester) segment can greatly increase the efficiency of drug entrapment making transport to tumors much more effective. HUMAN RESOURCES - --------------- As of February 28, 2003, we had 34 full-time employees, 8 of whom hold PhDs. There were 25 employees engaged in research and development and quality control, and 9 working in finance, business development, human resources and administration. We consider our relations with employees to be satisfactory. None of our employees is covered by a collective bargaining agreement. AVAILABLE INFORMATION - --------------------- We make available free of charge on or through our Internet website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports as soon as reasonably practicable after they are electronically filed with, or furnished to, the Securities and Exchange Commission. Our Internet website address is "www.appharma.com". Item 2. PROPERTIES We lease 26,067 square feet of laboratory, office and warehouse space in Redwood City, California. The current annual rent expense for the Redwood City facility is approximately $641,000. We occupied a production facility and warehouse in Lafayette, Louisiana that was sold to RP Scherer in July 2000. The construction of the facility in 1986 was financed primarily by 15-year, tax-exempt industrial development bonds. In 1995, we extinguished the bond liability through an "insubstance defeasance" transaction by placing United States government securities in an irrevocable trust to fund all future interest and principal payments. The defeased debt balance outstanding of $2,500,000 as of December 31, 2002 will be repaid on January 25, 2005 using the proceeds from the maturities of the United States government securities held in the irrevocable trust. Our existing research and development and administrative facilities are not yet being used at full capacity and management believes that these facilities are adequate and suitable for current and anticipated needs. Item 3. LEGAL PROCEEDINGS None. Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS None.

These are the first two of three possible contractual payments under the sale agreement. Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Summary of Critical Accounting Policies The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals. Actual results could differ materially from those estimates. The items in our financial statements requiring significant estimates and judgments are as follows: Revenue Recognition - ------------------- Royalties - --------- Contractually required minimum royalties are recorded ratably throughout the contractual period. Royalties in excess of minimum royalties are recognized as earned when the related product is shipped to the customer by our licensees based on information that we receive from our licensees. Contract Revenues - ----------------- We have licensing agreements that generally provide for us to receive periodic minimum payments, royalties, and/or non-refundable license fees. These licensing agreements typically require a non-refundable license fee and allow partners to sell our proprietary products in a defined field or territory for a defined period. The license agreements provide for us to earn future revenue through royalty payments. These non-refundable license fees are initially reported as deferred revenues and recognized as revenues over the estimated life of the product to which they relate as we have continuing involvement with licensees until the related product is discontinued. Revenue recognized from deferred license fees is classified as Contract Revenues in the accompanying consolidated statements of operations. License fees received in connection with arrangements where our company has no continuing involvement are recognized as contract revenues when the amounts are received or when collectibility is assured, whichever is earlier. A milestone payment is a payment made to us by a third party or corporate partner upon the achievement of a predetermined milestone as defined in a legally binding contract. Milestone payments are recognized as contract revenue when the milestone event has occurred and we have completed all milestone related services such that the milestone payment is currently due and is non-refundable. Contract revenues also relate to research and development arrangements that generally provide for our company to invoice research and development fees based on full-time equivalent hours for each project. Revenues from these arrangements are recognized as the related development costs are incurred. These revenues approximate the costs incurred. Product Revenues - ---------------- Product revenues relate to our sales of analytical standards for the calibration of turbidimeters used to test water purity and are recorded upon shipment of products when four basic criteria are met: 1) persuasive evidence of an arrangement exists, 2) delivery has occurred or services have been rendered, 3) the fee is fixed and determinable, and 4) collectibility is reasonably assured. Determination of criteria 3 and 4 are based on management's judgments regarding the fixed nature of the fees charged for products delivered and the collectibility of those fees. Should changes in conditions cause management to determine these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected. STATEMENTS OF OPERATIONS HIGHLIGHTS (in thousands) - -------------------------------------------------- For the Years Ended December 31, Annual % Change -------------------------------- --------------- 2002 2001 2000 02/01 01/00 ------ ------ ------ ----- ----- Royalties $4,026 $3,227 $2,081 25% 55% Contract revenues 644 38 122 1,595% (69%) Product sales 1,145 1,122 1,163 2% (4%) ------ ------ ------ Total revenues 5,815 4,387 3,366 33% 30% Expenses Cost of product sales 445 440 497 --% (11%) Research and development 6,699 7,348 3,713 (9%) 98% Selling and marketing 471 473 594 --% (20%) General and administrative 3,024 3,247 2,869 (7%) 13%

Results of Operations for the years ended December 31, 2002 and 2001 - -------------------------------------------------------------------- Except for statements of historical fact, the statements herein are forward- looking and are subject to a number of risks and uncertainties that could cause actual results to differ materially from the statements made. These include, among others, uncertainty associated with timely development, approval, launch and acceptance of new products, establishment of new corporate alliances, progress in research and development programs, and other risks described below or identified from time to time in our Securities and Exchange Commission filings. Our revenues are derived principally from royalties, license and research and development fees and sales of analytical standards products. Under strategic alliance arrangements entered into with certain corporations, we may receive non-refundable upfront fees, milestone payments and royalties based on third party product sales. Royalties for 2002 increased by $799,000 or 25%, to $4,026,000 from $3,227,000 in the prior year. This increase related to a 29% increase in royalties earned on sales of Carac(TM), a topical prescription treatment for actinic keratoses that was launched in the first quarter of 2001 by our marketing partner, Dermik Laboratories, an Aventis company. Also, royalties on sales of Retin-A(R) Micro by Ortho Neutrogena, a Johnson and Johnson company, increased by 23% over the prior year following the launch of a new low-dose formulation in July 2002 after FDA marketing clearance and a direct- to-consumer advertising program of the product. Royalty income is expected to increase in 2003 assuming continued market share growth for the Retin-A Micro product line, the continuation of Ortho Neutrogena's direct-to-consumer advertising program and the continued growth of Carac sales. Contract revenues for 2002 were $644,000 compared with $38,000 in the prior year. This was due to the initiation of collaborative research and development arrangements with prospective corporate partners during the year, and the forfeiture by a partner of certain rights to a proprietary Microsponge(R) formulation. Product revenues for 2002 relating to sales of analytical standards increased by 2% or $23,000 to $1,145,000 from $1,122,000 in the prior year. Gross profit on sales of analytical standards were flat at 61%. In February 2003, we sold the assets of APS Analytical Standards, Inc., to GFS Chemicals of Columbus, Ohio and do not expect to report product sales or cost of sales relating to this business in the future. Research and development expense for 2002 decreased by $649,000, or 9%, to $6,699,000 from $7,348,000 due mainly to the delayed entry into Phase II clinical trials of our product candidate for post-surgical pain management incorporating our Biochronomer(TM) drug delivery system. This compares with higher expenses incurred in the prior year related to preparation for the filing of an Investigational New Drug Application (IND), together with the costs associated with the manufacture of GMP materials for use in clinical programs. Research and development expense is expected to increase in 2003 as our lead product candidate enters Phase II human clinical studies in mid- year. The delay caused by the withdrawal of the Phase II protocol in August 2002 deferred a portion of the anticipated increase in research and development spending until 2003. This delay could result in a delay in the filing of a New Drug Application ("NDA") for APF112, and hence could result in a delay in the product candidate's marketing clearance and initiation of revenue streams. The scope and magnitude of future research and development expenses are difficult to predict at this time given the number of studies that will need to be conducted for any of our potential products. In general, biopharmaceutical development involves a series of steps, beginning with identification of a potential target, and includes proof of concept in animals and Phase I, II, and III clinical studies in humans. Each step of this process is typically more expensive than the previous one, so success in development results in increasing expenditures. Our research and development expenses currently include costs for scientific personnel, animal studies, supplies, equipment, consultants, patent filings, overhead allocation and sponsored research at academic and research institutions. Future research and development expenses would also include costs related to human clinical trials. Products in Development - ----------------------- We have a number of product candidates in various stages of development, some of which are the subject of collaborations with potential corporate partners. The following table sets forth the current opportunities for our own portfolio of product candidates, the compound selected, the delivery time and the status. CURRENT OPPORTUNITIES Drug Indication Compound Delivery Duration Status - ---------- -------- ----------------- ------ Acute pain relief Mepivacaine Less than 1 week Pre-Phase II (post-surgical) Site-specific Meloxicam 2-4 weeks Pre-IND Anti-inflammatory Chronic pain Relief Mepivacaine 4-6 weeks Preclinical Post-surgical Anti-adhesions Undisclosed Less than 1 week Research In addition, several feasibility studies are ongoing with corporate collaborators in the areas of ophthalmology, device coating, restenosis and immune stimulation. The major components of research and development expenses for 2002, 2001 and 2000 were as follows (in thousands): 2002 2001 2000 ------ ------ ------ Internal general research and development costs $4,827 $4,167 $2,879 External polymer development and preclinical programs 1,872 3,181 834 ----- ----- ----- $6,699 $7,348 $3,713 ===== ===== ===== Internal general research and development costs include employee salaries and benefits, laboratory supplies, depreciation, professional fees and allocation of overhead. External polymer development and preclinical programs include expenditures on technology and product development, preclinical evaluation, regulatory and toxicology consultants, and polymer manufacturing, all of which are performed by third parties. Selling and marketing expense for analytical standards products for 2002 was essentially flat at $471,000 compared with $473,000 in the prior year. Following the sale of the Analytical Standards business in February 2003 we will not incur these selling and marketing expenses. General and administrative expense for 2002 of $3,024,000 decreased by $223,000 or 7% from $3,247,000 in the prior year due mainly to decreased professional fees and a provision for doubtful note receivable, partially offset by higher investor relations expenses. General and administrative expense includes salaries and related expenses, professional fees, directors' fees, investor relations costs, insurance expense and overhead allocation, and is expected to be consistent in 2003. General and administrative expenses in 2001 included an allowance for doubtful accounts of $418,000 relating to a note receivable arising from our sale of certain proprietary rights to a consumer product in 1999. As payments on the note were not received on a timely basis, an allowance was recorded against the note. In 2002, an additional allowance of $19,000 was recorded on the remaining outstanding balance, net of payments received. Payments received were recorded as recovery of the receivable. Interest income for 2002 decreased by $516,000 to $590,000 from $1,106,000 due mainly to reduced interest rates on reduced cash balances. Interest income is expected to decrease in 2003 as cash balances decrease. On July 25, 2000, we completed the sale of certain technology rights for topical pharmaceuticals and cosmeceutical product lines and associated assets to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. Income (loss) from discontinued operations represents the net contribution (loss) attributable to the cosmeceutical and toiletries product lines which were sold to RP Scherer Corporation in July 2000. For the year 2002, the net income from discontinued operations relating to changes in estimates totaled $172,000, compared with $525,000 in the prior year. The gain on disposition of discontinued operations recorded in 2002 of $216,000 related mainly to the net earnout income resulting from the sale of our cosmeceutical product lines in 2000, compared with $2,890,000 in the prior year. The earnout income is the second of three contractual annual payments, the amounts of which are dependent on the performance of the cosmeceutical business. Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer's combined sales of products to Ortho Neutrogena and Dermik ("Gross Profit Guaranty"). The guaranty period commenced on July 1, 2000 and ends on the earlier of July 1, 2010 or the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equals or exceeds the guaranteed gross profit. Payments for the Gross Profit Guaranty aggregated $243,000 for the first two guaranty years. We expect the annual Gross Profit Guaranty payments to range from approximately $100,000 to $150,000 for the remainder of the guaranty period. Results of Operations for the years ended December 31, 2001 and 2000 - -------------------------------------------------------------------- Royalties for 2001 increased by $1,146,000 or 55%, to $3,227,000 from $2,081,000 in 2000. This increase related primarily to royalties earned on sales of Carac(TM), a topical prescription treatment for actinic keratoses which was launched in the first quarter of 2001 by our marketing partner, Dermik Laboratories, an Aventis company. Royalties on sales of Retin-A(R) Micro by Ortho Neutrogena, a Johnson and Johnson company, also increased following a direct-to-consumer advertising program of the product. Product revenues for 2001 relating to sales of analytical standards decreased by 4% or $41,000 to $1,122,000 from $1,163,000 in 2000. Gross profit on sales of analytical standards increased from 57% to 61% due mainly to a change in the sales mix with fewer sales of lower margin instruments. Research and development expense for 2001 increased by $3,635,000, or 98%, to $7,348,000 from $3,713,000 in 2000 due mainly to costs of preclinical studies required for the filing of an Investigational New Drug Application (IND) involving our bioerodible Biochronomer(TM) drug delivery system for a treatment for post-surgical pain, and our ongoing product development programs. Selling and marketing expense for analytical standards products for 2001 decreased by $121,000 or 20% to $473,000 from $594,000 in 2000 due mainly to lower advertising expenses on sales of analytical standards. General and administrative expense for 2001 of $3,247,000 increased by $378,000 or 13% over 2000 due mainly to a reserve recorded on a note receivable. General and administrative expense includes salaries and related expenses, professional fees, directors' fees, investor relations costs, insurance expense and overhead allocation. Interest income for 2001 increased by $289,000, or 35%, to $1,106,000 from $817,000 in 2000 due mainly to the receipt of $25 million in July 2000 as proceeds from the sale of our cosmeceutical and toiletries product lines to RP Scherer Corporation. Interest expense for 2001 decreased by $294,000, or 100%, to $0 due to the repayment of all previously outstanding debt upon the Company's receipt of the $25 million proceeds from RP Scherer. On July 25, 2000, we completed the sale of certain technology rights for topical pharmaceuticals and its cosmeceutical product lines and associated assets to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. Income/loss from discontinued operations represents the net contribution/loss attributable to the cosmeceutical and toiletries product lines which were sold to RP Scherer Corporation in July 2000. For the year 2001, the net income from discontinued operations totaled $525,000, compared with $1,163,000 in 2000. The gain recorded in 2001 related to the disposition of discontinued operations includes net earnout income of approximately $3 million from the sale of our cosmeceutical product lines in the prior year, which represents additional earnout income of $3.6 million less reserves for certain indemnification claims allowable under the sale agreement. The earnout income is the first of three contractual annual payments. The gain on disposition of discontinued operations in the prior year represents the gain realized on the sale of the cosmeceutical business completed in July 2000. Capital Resources and Liquidity - ------------------------------- Total assets as of December 31, 2002 were $17,799,000 compared with $23,507,000 at December 31, 2001. Cash, cash equivalents and marketable securities decreased by $5,373,000 to $14,121,000 at December 31, 2002 from $19,494,000 at December 31, 2001. Net cash used in operating activities for the years ended December 31, 2002, 2001 and 2000 was $5,131,000, $6,491,000 and $3,116,000, respectively. The decrease in net cash used in operating activities from 2001 to 2002 was primarily due to reduced research and development expenses resulting from the delay in the initiation of the Phase II human clinical studies for our product candidate for post-surgical pain. Net cash provided by investing activities for the years ended December 31, 2002, 2001 and 2000 was $4,720,000, $3,550,000 and $8,972,000, respectively, with decreasing proceeds from the sale of our discontinued operations in each of 2001 and 2002, offset by higher net sales of marketable securities in 2002. Net cash provided by financing activities was $75,000 for the year ended December 31, 2002 compared to $66,000 for the year ended December 31, 2001 and net cash used in financing activities of $3,068,000 for the year ended December 31, 2000. The net cash provided by financing activities in 2002 and 2001 was mainly due to proceeds from issuances of shares under the Employee Stock Purchase Plan. The cash used in financing activities in 2000 was primarily the result of the repayment of our long-term debt. In the current year, we have also financed our operations, including technology and product research and development, from royalties received on sales of Retin-A Micro and Carac, earnout income from RP Scherer, the profits from the sale of analytical standard products and interest earned on short- term investments. On February 13, 2002 ("closing date"), we completed the sale of the assets of our wholly-owned subsidiary, APS Analytical Standards, Inc. to GFS Chemicals, Inc., a private company based in Columbus, Ohio. We received $2.1 million in cash on the closing date and we are entitled to receive royalties on sales varying from 5% to 15% for five years following the closing, with guaranteed minimum annual royalty payments. Our existing cash and cash equivalents, marketable securities, collections of trade accounts receivable, together with interest income and other revenue- producing activities including royalties, license and option fees and research and development fees, are expected to be sufficient to meet our cash needs for at least the next two years, assuming no changes to existing business plans. Our future capital requirements will depend on numerous factors including, among others, royalties from sales of products of third party licensees; our ability to enter into collaborative research and development and licensing agreements; progress of product candidates in preclinical and clinical trials; investment in new research and development programs; time required to gain regulatory approvals; resources that we devote to self-funded products; potential acquisitions of technology, product candidates or businesses; and the costs of defending or prosecuting any patent opposition or litigation necessary to protect our proprietary technology. We occupy leased facilities under an agreement that expires in two years. We also lease certain office equipment under operating leases. The contractual obligations for the next five years and thereafter are as follows, in thousands: Years Ending Minimum December 31, Payments ----------- -------- 2003 $ 705 2004 602 2005 12 2006 7 ----- $1,326 ===== Reclassifications - ----------------- Certain reclassifications have been made to the prior year financial statements to conform with the presentation in 2002. The provision for doubtful note receivable in 2001 was reclassified from income from discontinued operations to general and administrative expenses. A milestone payment received in 2001 was reclassified from royalty revenue to contract revenues. License, research and development, and option fees were reclassified to contract revenues. Recent Accounting Pronouncements - -------------------------------- In July 2001, the FASB issued FAS 141, "Business Combinations" (FAS 141). FAS 141 supersedes APB 16, "Business Combinations," and FAS 38, "Accounting for Preacquisition Contingencies of Purchased Enterprises." FAS 141 requires the purchase method of accounting for all business combinations initiated after June 30, 2001 and eliminates the pooling-of-interests method. FAS 141 also includes guidance on the initial recognition and measurement of goodwill and other intangible assets arising from business combinations completed after June 30, 2001. The adoption of FAS 141 did not have a material effect on our financial position or results of operations. In July 2001, the FASB issued FAS 142, "Goodwill and Other Intangible Assets" (FAS 142). FAS 142 supersedes APB 17, "Intangible Assets," and requires the discontinuance of goodwill amortization. In addition, FAS 142 includes provisions regarding the reclassification of certain existing recognized intangibles as goodwill, reassessment of the useful lives of existing recognized intangibles, reclassification of certain intangibles out of previously reported goodwill and the testing for impairment of existing goodwill and other intangibles out of previously reported goodwill and other intangibles. FAS 142 was required to be applied for fiscal years beginning after December 15, 2001, with certain early adoption permitted. The adoption of FAS 142 did not have a material effect on our financial position or results of operations. In August 2001, the FASB issued FAS 143, "Accounting for Asset Retirement Obligations" (FAS 143). FAS 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. FAS 143 was effective for our year ended December 31, 2002, and did not have a material effect on our financial position or results of operations. In October 2001, the FASB issued FAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (FAS 144), which supersedes FAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" (FAS 121). FAS 144 addresses financial accounting and reporting for the impairmment of long-lived assets and for long-lived assets to be disposed of. However, FAS 144 retains the fundamental provisions of FAS 121 for: 1) recognition and measurement of the impairment of long-lived assets to be held and used; and 2) measurement of long-lived assets to be disposed of by sale. FAS 144 was effective for fiscal years beginning after December 15, 2001. The adoption of FAS 144 did not have a material effect on our financial condition or results of operations. In June 2002, the FASB issued FAS 146, "Accounting for Costs Associated with Exit or Disposal Activities," which addresses accounting for restructuring, discountinued operation, plant closing, or other exit or disposal activity. FAS 146 requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. FAS 146 is to be applied prospectively to exit or disposal activities initiated after December 31, 2002. The adoption of FAS 146 is not expected to have a significant impact on our financial position or results of operations. In November 2002, the FASB issued Interpretation No. 45 (or FIN 45), "Guarantor's Accounting and Disclosure requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." FIN 45 elaborates on the existing disclosure requirements for most guarantees, including residual value guarantees issued in conjunction with operating lease agreements. It also clarifies that at the time a company issues a guarantee, the company must recognize an initial liability for the fair value of the obligation it assumes under that guarantee and must disclose that information in its interim and annual financial statements. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002. The adoption of the disclosure requirements in November 2002 and the recognition requirements in January 2003 of FIN 45 neither had nor are anticipated to have a material impact on our results of operations or financial position. In November 2002, the FASB issued Emerging Issues Task Force (EITF) Issue No. 00-21, "Revenue Arrangements with Multiple Deliverables." EITF Issue No. 00- 21 addresses certain aspects of the accounting by a company for arrangements under which it will perform multiple revenue-generating activities. EITF Issue No. 00-21 addresses when and how an arrangement involving multiple deliverables should be divided into separate units of accounting. EITF Issue No. 00-21 provides guidance with respect to the effect of certain customer rights due to company nonperformance on the recognition of revenue allocated to delivered units of accounting. EITF Issue No. 00-21 also addresses the impact on the measurement and/or allocation of arrangement consideration of customer cancellation provisions and consideration that varies as a result of future actions of the customer or the company. Finally, EITF Issue No. 00-21 provides guidance with respect to the recognition of the cost of certain deliverables that are excluded from the revenue accounting for an arrangement. The provisions of EITF Issue No. 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We are currently evaluating the effect that the adoption of EITF Issue No. 00-21 will have on our results of operations and financial position. In December 2002, the FASB issued Statement No. 148, "Accounting for Stock- Based Compensation - Transition and Disclosure" (or FAS 148). FAS 148 amends FAS 123 "Accounting for Stock-Based Compensation" to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, FAS 148 amends the disclosure requirements of FAS 123 to require more prominent disclosures in both annual and interim financial statements about the method used on reported results. The additional disclosure requirements of FAS 148 are effective for fiscal years ending after December 15, 2002. We have elected to continue to follow the intrinsic value method of accounting as prescribed by Accounting Principles Board Opinion No. 25 (or APB 25), "Accounting for Stock Issued to Employees," to account for employee stock options, and have adopted the disclosure requirements of FAS 148. In January 2003, the FASB issued Interpretation No. 46 (or FIN 46), "Consolidation of Variable Interest Entities." FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or entitled to receive a majority of the entity's residual returns or both. The consoidation requirements of FIN 46 apply immediately to variable interest entities created after January 31, 2003. The consolidation requirements apply to older entities in the first fiscal year or interim period beginning after June 15, 2003. Certain of the disclosure requirements apply to all financial statements issued after January 31, 2003, regardless of when the variable interest entity was established. We do not have variable interest entities and do not expect the adoption of FIN 46 to have a material impact on our results of operations and financial position. ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS - ------------------------------------------------- Our business is subject to various risks, including those described below. You should carefully consider these risk factors, together with all of the other information included in this Form 10-K. Any of these risks could materially adversely affect our business, operating results and financial condition. OUR BIOERODIBLE DRUG DELIVERY SYSTEM BUSINESS IS AT AN EARLY STAGE OF DEVELOPMENT. Our bioerodible drug delivery system business is at an early stage of development. Our ability to produce bioerodible drug delivery systems that progress to and through clinical trials is subject to, among other things: - success with our research and development efforts; - selection of appropriate therapeutic compounds for delivery; - the required regulatory approval. Successful development of delivery systems will require significant preclinical and clinical testing prior to regulatory approval in the United States and elsewhere. In addition, we will need to determine whether any potential products can be manufactured in commercial quantities at an acceptable cost. Our efforts may not result in a product that can be marketed. Because of the significant scientific, regulatory and commercial milestones that must be reached for any of our research programs to be successful, any program may be abandoned, even after significant resources have been expended. WE MAY NEED ADDITIONAL CAPITAL TO CONDUCT OUR OPERATIONS AND DEVELOP OUR PRODUCTS, AND OUR ABILITY TO OBTAIN THE NECESSARY FUNDING IS UNCERTAIN. We may require additional capital resources in order to conduct our operations and develop our products. While we estimate that our existing capital resources, royalty income and interest income will be sufficient to fund our current level of operations for at least the next two years based on current business plans, we cannot guarantee that this will be the case. The timing and degree of any future capital requirements will depend on many factors, including: - continued scientific progress in our research and development programs; - the magnitude and scope of our research and development programs; - our ability to maintain and establish strategic collaborations or partnerships for research, development, clinical testing, manufacturing and marketing; - our progress with preclinical and clinical trials; - the time and costs involved in obtaining regulatory approvals; - the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims. We intend to acquire additional funding through strategic collaborations, in the form of license fees, research and development fees and milestone payments. In the event that additional funds are obtained through arrangements with collaborative partners, these arrangements may require us to relinquish rights to some of our technologies, product candidates or products that we would otherwise seek to develop and commercialize ourselves. If sufficient funding is not available, we may be required to delay, reduce the scope of or eliminate one or more of our research or development programs, each of which could have a material adverse effect on our business. ENTRY INTO CLINICAL TRIALS WITH ONE OR MORE PRODUCTS MAY NOT RESULT IN ANY COMMERCIALLY VIABLE PRODUCTS. We do not expect to generate any significant revenues from product sales for a period of several years. We may never generate revenues from product sales or become profitable because of a variety of risks inherent in our business, including risks that: - clinical trials may not demonstrate the safety and efficacy of our products; - completion of clinical trials may be delayed, or costs of clinical trials may exceed anticipated amounts; - we may not be able to obtain regulatory approval of our products, or may experience delays in obtaining such approvals; - we and our licensees may not be able to successfully market our products. BECAUSE WE OR OUR COLLABORATORS MUST OBTAIN REGULATORY APPROVAL TO MARKET OUR PRODUCTS IN THE UNITED STATES AND FOREIGN JURISDICTIONS, WE CANNOT PREDICT WHETHER OR WHEN WE WILL BE PERMITTED TO COMMERCIALIZE OUR PRODUCTS. Federal, state and local governments in the United States and governments in other countries have significant regulations in place that govern many of our activities. The preclinical testing and clinical trials of the products that we develop ourselves or that our collaborators develop are subject to government regulation and may prevent us from creating commercially viable products from our discoveries. In addition, the sale by us or our collaborators of any commercially viable product will be subject to government regulation from several standpoints, including the processes of: - manufacturing; - advertising and promoting; - selling and marketing; - labeling; and - distributing. We may not obtain regulatory approval for the products we develop and our collaborators may not obtain regulatory approval for the products they develop. Regulatory approval may also entail limitations on the indicated uses of a proposed product. The regulatory process, particularly for biopharmaceutical products like ours, is uncertain, can take many years and requires the expenditure of substantial resources. Any product that we or our collaborative partners develop must receive all relevant regulatory agency approvals or clearances, if any, before it may be marketed in the United States or other countries. In particular, human pharmaceutical therapeutic products are subject to rigorous preclinical and clinical testing and other requirements by the Food and Drug Administration in the United States and similar health authorities in foreign countries. The regulatory process, which includes extensive preclinical testing and clinical trials of each product in order to establish its safety and efficacy, is uncertain, can take many years and requires the expenditure of substantial resources. Data obtained from preclinical and clinical activities is susceptible to varying interpretations that could delay, limit or prevent regulatory agency approvals or clearances. In addition, delays or rejections may be encountered as a result of changes in regulatory agency policy during the period of product development and/or the period of review of any application for regulatory agency approval or clearance for a product. Delays in obtaining regulatory agency approvals or clearances could: - significantly harm the marketing of any products that we or our collaborators develop; - impose costly procedures upon our activities or the activities of our collaborators; - diminish any competitive advantages that we or our collaborative partners may attain; or - adversely affect our ability to receive royalties and generate revenues and profits. In addition, the marketing and manufacturing of drugs and biological products are subject to continuing FDA review, and later discovery of previously unknown problems with a product, its manufacture or its marketing may result in the FDA requiring further clinical research or restrictions on the product or the manufacturer, including withdrawal of the product from the market. WE DEPEND ON OUR COLLABORATORS TO HELP US COMPLETE THE PROCESS OF DEVELOPING AND TESTING OUR PRODUCTS AND OUR ABILITY TO DEVELOP AND COMMERCIALIZE PRODUCTS MAY BE IMPAIRED OR DELAYED IF OUR COLLABORATIVE PARTNERSHIPS ARE UNSUCCESSFUL. Our strategy for the development, clinical testing and commercialization of our products requires entering into collaborations with corporate partners, licensors, licensees and others. We are dependent upon the subsequent success of these other parties in performing their respective responsibilities and the cooperation of our partners. Our collaborators may not cooperate with us or perform their obligations under our agreements with them. We cannot control the amount and timing of our collaborators' resources that will be devoted to our research activities related to our collaborative agreements with them. Our collaborators may choose to pursue existing or alternative technologies in preference to those being developed in collaboration with us. Under agreements with collaborators, we may rely significantly on them, among other activities, to: - fund research and development activities with us; - pay us fees upon the achievement of milestones; and - market with us any commercial products that result from our collaborations. OUR RELIANCE ON THE RESEARCH ACTIVITIES OF OUR NON-EMPLOYEE SCIENTIFIC ADVISORS AND OTHER RESEARCH INSTITUTIONS, WHOSE ACTIVITIES ARE NOT WHOLLY WITHIN OUR CONTROL, MAY LEAD TO DELAYS IN TECHNOLOGICAL DEVELOPMENTS. We have relationships with scientific advisors at academic and other institutions, some of whom conduct research at our request. These scientific advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. We have limited control over the activities of these advisors and, except as otherwise required by our collaboration and consulting agreements, can expect only limited amounts of their time to be dedicated to our activities. If our scientific advisors are unable or refuse to contribute to the development of any of our potential discoveries, our ability to generate significant advances in our technologies will be significantly harmed. THE LOSS OF KEY PERSONNEL COULD SLOW OUR ABILITY TO CONDUCT RESEARCH AND DEVELOP PRODUCTS. Our future success depends to a significant extent on the skills, experience and efforts of our executive officers and key members of our scientific staff. We may be unable to retain our current personnel or attract or assimilate other highly qualified management and scientific personnel in the future. The loss of any or all of these individuals could harm our business and might significantly delay or prevent the achievement of research, development or business objectives. WE FACE INTENSE COMPETITION FROM OTHER COMPANIES. Most or all of the products we could develop or commercialize will face competition from different therapeutic agents intended for treatment of the same indications or from other products incorporating drug delivery technologies. The competition potentially includes all of the pharmaceutical companies in the world. Many of these pharmaceutical companies have more financial resources, technical staff and manufacturing and marketing capabilities than we do. To the extent that we develop or market products incorporating drugs that are off-patent, or are being developed by multiple companies, we will face competition from other companies developing and marketing similar products. Pharmaceutical companies are increasingly using advertising, including direct-to-consumer advertising, in marketing their products. The costs of such advertising are very high and are increasing. It may be difficult for our company to compete with larger companies investing greater resources in these marketing activities. Other pharmaceutical companies are aggressively seeking to obtain new products by licensing products or technology from other companies. We will be competing to license or acquire products or technology with companies with far greater financial and other resources. INABILITY TO OBTAIN SPECIAL MATERIALS COULD SLOW DOWN OUR RESEARCH AND DEVELOPMENT PROCESS. Some of the critical materials and components used in our developed products are sourced from a single supplier. An interruption in supply of a key material could significantly delay our research and development process. Special materials must often be manufactured for the first time for use in drug delivery systems, or materials may be used in the systems in a manner different from their customary commercial uses. The quality of materials can be critical to the performance of a drug delivery system, so a reliable source of a consistent supply of materials is important. Materials or components needed for our drug delivery systems may be difficult to obtain on commercially reasonable terms, particularly when relatively small quantities are required, or if the materials traditionally have not been used in pharmaceutical products. PATENTS AND OTHER INTELLECTUAL PROPERTY PROTECTION MAY BE DIFFICULT TO OBTAIN OR INEFFECTIVE. Patent protection generally has been important in the pharmaceutical industry. Our existing patents may not cover future products, additional patents may not be issued, and current patents or patents issued in the future may not provide meaningful protection or prove to be of commercial benefit. In the United States, patents are granted for specified periods of time. Some of our earlier patents have expired, or will expire, over the next several years. Other companies may successfully challenge our patents in the future. Others may also challenge the validity or enforceability of our patents in litigation. If any challenge is successful, other companies may then be able to use the invention covered by the patent without payment. In addition, if other companies are able to obtain patents that cover any of our technologies or products, we may be subject to liability for damages and our activities could be blocked by legal action unless we can obtain licenses to those patents. In addition, we utilize significant unpatented proprietary technology and rely on unpatented trade secrets and proprietary know-how to protect certain aspects of our products and technologies and the methods used to manufacture them. Other companies have or may develop similar technology which will compete with our technology. OUR ROYALTY REVENUES COULD DECLINE. Our royalty revenues in future periods could vary significantly. Major factors which could have an effect on our royalty revenues include, but are not limited to: - our partners' decisions about amounts and timing of advertising support for Retin-A Micro and Carac. - our partners' decisions about other promotion and marketing support for Retin-A Micro and Carac. - the timing of approvals for new product applications both in the United States and abroad. - the expiration or invalidation of patents. - decreases in licensees' sales of product due to competition, manufacturing difficulties or other factors that affect sales of product, including regulatory restrictions on the advertising of pharmaceutical products. Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK Our exposure to market rate risk for changes in interest rates relates primarily to our investment portfolio. We do not use derivative financial instruments. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments of high credit quality and relatively short average maturities. We also manage our interest rate risk by maintaining sufficient cash and cash equivalents such that we are typically able to hold our investments to maturity. At December 31, 2002 and 2001, respectively, our cash equivalents and marketable securities include corporate and other debt securities of approximately $13,665,000 and $19,289,000. Short-term investments with effective maturities of less than three months totaled approximately $2,826,000 and $3,412,000 at December 31, 2002 and 2001, respectively. Investments with maturities between three months and one year at December 31, 2002 and 2001, respectively, totaled $5,618,000 and $7,102,000. Investments with maturities between one and two years totaled $5,221,000 and $8,775,000 at December 31, 2002 and 2001, respectively. Notwithstanding our efforts to manage interest rate risks, there can be no assurances that we will be adequately protected against the risks associated with interest rate fluctuations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - ------------------------------------------ DECEMBER 31, 2002, 2001 AND 2000 - -------------------------------- Note 1 Business A.P. Pharma, Inc. ("APP") is developing patented polymer-based delivery systems to enhance the safety and effectiveness of pharmaceutical compounds. Projects are currently conducted under feasibility and development arrangements with pharmaceutical and biotechnology companies. New products and technologies under development include bioerodible polymers for injectable and implantable drug delivery. On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceuticals and cosmeceutical product lines and other assets ("cosmeceutical and toiletry business") to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. The terms of the agreement with RP Scherer provided for a payment of $25 million at closing and additional earnout amounts based on the performance of business sold over a period of three years ending June 30, 2003. We received an aggregate of $3.8 million during the first two years of the earnout period. We are entitled to receive an additional amount in 2003 which will depend on the performance of the business sold (see Note 11 "Discontinued Operations"). Note 2 Summary of Significant Accounting Policies Principles of Consolidation - --------------------------- The consolidated financial statements include the financial statements of APP and its wholly owned subsidiary, APS Analytical Standards, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. Cash Equivalents and Marketable Securities - ------------------------------------------ For purposes of the Consolidated Statements of Cash Flows and Consolidated Balance Sheets, we consider all short-term investments that have original maturities of less than three months to be cash equivalents. Investments with effective maturities longer than three months are classified as marketable securitites. Investments consist primarily of commercial paper, bankers acceptances, master notes and corporate debt securities. We have classified all our investments in certain debt and equity securities as "available-for-sale", and therefore are recorded at fair value with unrealized gains and losses reported as a separate component of shareholders' equity. Financial Instruments - --------------------- The carrying value of our financial instruments, including marketable securities and accounts receivable, approximate fair value. Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments and trade accounts receivable. We invest excess cash in a variety of high grade short- term, interest-bearing securities. This diversification of risk is consistent with our policy to ensure safety of principal and maintain liquidity. Allowance for Doubtful Accounts and Note Receivable - --------------------------------------------------- Allowances are recorded for accounts and note receivable at such time management determines that the collection of those receivables is not reasonably assured. Interest income under the terms of note receivable agreement is recorded when cash is received or collectiblity is reasonably assured. The note receivable, net of the related reserve, is included in prepaid expenses and other assets in the accompanying balance sheet. Inventory - --------- Inventory is stated at the lower of cost or market value, utilizing the average cost method. Property and Equipment - ---------------------- Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: equipment and machinery, 3 to 5 years; furniture and fixtures, 5 years; and leasehold improvements, over the shorter of the respective lease terms or the respective useful lives of the leasehold improvements. Long-Lived Assets - ----------------- As circumstances dictate, we evaluate whether changes have occurred that would require revision of the remaining estimated lives of recorded long- lived assets or that render those assets not recoverable. Recoverability of assets to be held and used is determined by comparing the undiscounted net cash flows of long-lived assets to their respective carrying values. If such assets are considered to be impaired, the amount of impairment to be recognized is measured based on the projected discounted cash flows using an appropriate discount rate. See "Recent Accounting Pronouncements". Stock-Based Compensation - ------------------------ We have elected to account for stock-based compensation related to employees using the intrinsic value method. Accordingly, except for stock options issued to non-employees and restricted stock awards to employees and directors, no compensation cost has been recognized for our stock option plans and stock purchase plan. Compensation related to options granted to non-employees is periodically remeasured as earned. In accordance with FAS No. 123, "Accounting for Stock-Based Compensation," as amended by FAS No. 148, "Accounting for Stock-Based Compensation-Transition and Disclosure," we have provided, below, the pro forma disclosures of the effect on net income (loss) and income (loss) per share as if FAS No. 123 had been applied in measuring compensation expense for all periods presented (see Note 9 "Shareholders' Equity"). 2002 2001 2000 ----------- ----------- --------- Net income (loss) - as reported $(3,778) $(2,514) $ 8,552 Add back: Deduct: Stock-based employee compensation expense determined under FAS 123 (601) (696) (1,293) ------- -------- ------- Net income (loss) - pro-forma $(4,379) $(3,210) $7,259 ====== ====== ====== Basic income (loss) per common share - as reported $(0.19) $(0.12) $0.42 Basic income (loss) per common share - pro-forma $(0.21) $(0.16) $0.36 Diluted income (loss) per common share - as reported $(0.19) $(0.12) $0.42 Diluted income (loss) per common share - pro-forma $(0.21) $(0.16) $0.36 Use of Estimates - ---------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals. Actual results could differ materially from those estimates. Revenue Recognition - ------------------- Royalties - --------- Contractually required minimum royalties are recorded ratably throughout the contractual period. Royalties in excess of minimum royalties are recognized as earned when the related product is shipped to the end customer by our licensees based on information provided to us by our licensees. Contract Revenues - ----------------- We have licensing agreements that generally provide for periodic minimum payments, royalties, and/or non-refundable license fees. These licensing agreements typically require a non-refundable license fee and allow our partners to sell our proprietary products in a defined field or territory for a defined period. The license agreements provide for APP to earn future revenue through royalty payments. These non-refundable license fees are initially reported as deferred revenues and recognized as revenues over the estimated life of the product to which they relate as we have continuing involvement with licensees until the related product is discontinued. Revenue recognized from deferred license fees is classified as Contract revenues in the accompanying consolidated statements of operations. License fees received in connection with arrangements where we have no continuing involvement are recognized as contract revenues when the amounts are received or when collectibility is assured, whichever is earlier. A milestone payment is a payment made by a third party or corporate partner to us upon the achievement of a predetermined milestone as defined in a legally binding contract. Milestone payments are recognized as contact revenue when the milestone event has occurred and we have completed all milestone related services such that the milestone payment is currently due and is non-refundable. Contract revenues also relate to research and development arrangements that generally provide for the company to invoice research and development fees based on full-time equivalent hours for each project. Revenues from these arrangements are recognized as the related development costs are incurred. These revenues approximate the costs incurred. Product Revenues - ---------------- Product revenues relate to our sales of analytical standards for the calibration of turbidimeters used to test water purity and are recorded upon shipment of products when four basic criteria are met: 1) persuasive evidence of an arrangement exists, 2) delivery has occurred or services have been rendered, 3) the fee is fixed and determinable, and 4) collectibility is reasonably assured. Determination of criteria 3 and 4 are based on management's judgments regarding the fixed nature of the fees charged for products delivered and the collectibility of those fees. Should changes in conditions cause management to determine these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected. Earnings (Loss) Per Share - ------------------------- Basic earnings (loss) per share is computed based on the weighted-average number of common shares outstanding. Diluted earnings per share is computed based on the weighted-average number of common shares outstanding and dilutive potential common shares outstanding. See Note 10 "Earnings Per Share". Concentrations of Credit Risk - ----------------------------- Financial instruments which potentially expose our company to concentrations of credit risk consist primarily of trade accounts receivable and receivables from contract revenues. Approximately 70% and 82% of the trade receivables and receivables from contract revenues were concentrated with two customers in the pharmaceutical industry as of December 31, 2002 and 2001, respectively. Approximately 73%, 75% and 62% of the net sales were concentrated with two, two and one customers for the years ended December 31, 2002, 2001 and 2000, respectively. To reduce credit risk, we perform ongoing credit evaluations of our customers' financial conditions. We do not generally require collateral for customers with accounts receivable balances. Segment and Geographic Information - ---------------------------------- Our operations are confined to a single business segment, the design and commercialization of polymer technologies for pharmaceutical and other applications. Substantially all of our revenues are derived from customers within the United States. Royalty and contract revenues from two domestic customers amounted to approximately 44% and 29% of total revenues for the year ended December 31, 2002. Royalty revenues from two domestic customers amounted to approximately 49% and 26% of total revenues for the year ended December 31, 2001. Revenues from one domestic customer amounted to 62% for the year ended December 31, 2000. Recent Accounting Pronouncements - -------------------------------- In July 2001, the FASB issued FAS 141, "Business Combinations" (FAS 141). FAS 141 supersedes APB 16, "Business Combinations," and FAS 38, "Accounting for Preacquisition Contingencies of Purchased Enterprises." FAS 141 requires the purchase method of accounting for all business combinations initiated after June 30, 2001 and eliminates the pooling-of-interests method. FAS 141 also includes guidance on the initial recognition and measurement of goodwill and other intangible assets arising from business combinations completed after June 30, 2001. The adoption of FAS 141 did not have a material effect on our financial position or results of operations. In July 2001, the FASB issued FAS 142, "Goodwill and Other Intangible Assets" (FAS 142). FAS 142 supersedes APB 17, "Intangible Assets," and requires the discontinuance of goodwill amortization. In addition, FAS 142 includes provisions regarding the reclassification of certain existing recognized intangibles as goodwill, reassessment of the useful lives of existing recognized intangibles, reclassification of certain intangibles out of previously reported goodwill and the testing for impairment of existing goodwill and other intangibles out of previously reported goodwill and other intangibles. FAS 142 was required to be applied for fiscal years beginning after December 15, 2001, with certain early adoption permitted. The adoption of FAS 142 did not have a material effect on our financial position or results of operations. In August 2001, the FASB issued FAS 143, "Accounting for Asset Retirement Obligations" (FAS 143). FAS 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. FAS 143 was effective for our year ended December 31, 2002, and did not have a material effect on our financial position or results of operations. In October 2001, the FASB issued FAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (FAS 144), which supersedes FAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" (FAS 121). FAS 144 addresses financial accounting and reporting for the impairmment of long-lived assets and for long-lived assets to be disposed of. However, FAS 144 retains the fundamental provisions of FAS 121 for: 1) recognition and measurement of the impairment of long-lived assets to be held and used; and 2) measurement of long-lived assets to be disposed of by sale. FAS 144 was effective for fiscal years beginning after December 15, 2001. The adoption of FAS 144 did not have a material effect on our financial condition or results of operations. In June 2002, the FASB issued FAS 146, "Accounting for Costs Associated with Exit or Disposal Activities," which addresses accounting for restructuring, discountinued operation, plant closing, or other exit or disposal activity. FAS 146 requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. FAS 146 is to be applied prospectively to exit or disposal activities initiated after December 31, 2002. The adoption of FAS 146 is not expected to have a significant impact on our financial position or results of operations. In November 2002, the FASB issued Interpretation No. 45 (or FIN 45), "Guarantor's Accounting and Disclosure requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." FIN 45 elaborates on the existing disclosure requirements for most guarantees, including residual value guarantees issued in conjunction with operating lease agreements. It also clarifies that at the time a company issues a guarantee, the company must recognize an initial liability for the fair value of the obligation it assumes under that guarantee and must disclose that information in its interim and annual financial statements. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002. The adoption of the disclosure requirements in November 2002 and the recognition requirements in January 2003 of FIN 45 neither had nor are anticipated to have a material impact on our results of operations or financial position. In November 2002, the FASB issued Emerging Issues Task Force (EITF) Issue No. 00-21, "Revenue Arrangements with Multiple Deliverables." EITF Issue No. 00- 21 addresses certain aspects of the accounting by a company for arrangements under which it will perform multiple revenue-generating activities. EITF Issue No. 00-21 addresses when and how an arrangement involving multiple deliverables should be divided into separate units of accounting. EITF Issue No. 00-21 provides guidance with respect to the effect of certain customer rights due to company nonperformance on the recognition of revenue allocated to delivered units of accounting. EITF Issue No. 00-21 also addresses the impact on the measurement and/or allocation of arrangement consideration of customer cancellation provisions and consideration that varies as a result of future actions of the customer or the company. Finally, EITF Issue No. 00-21 provides guidance with respect to the recognition of the cost of certain deliverables that are excluded from the revenue accounting for an arrangement. The provisions of EITF Issue No. 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We are currently evaluating the effect that the adoption of EITF Issue No. 00-21 will have on our results of operations and financial position. In December 2002, the FASB issued Statement No. 148, "Accounting for Stock- Based Compensation - Transition and Disclosure" (or FAS 148). FAS 148 amends FAS 123 "Accounting for Stock-Based Compensation" to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, FAS 148 amends the disclosure requirements of FAS 123 to require more prominent disclosures in both annual and interim financial statements about the method used on reported results. The additional disclosure requirements of FAS 148 are effective for fiscal years ending after December 15, 2002. We have elected to continue to follow the intrinsic value method of accounting as prescribed by Accounting Principles Board Opinion No. 25 (or APB 25), "Accounting for Stock Issued to Employees," to account for employee stock options, and have adopted the disclosure requirements of FAS 148. In January 2003, the FASB issued Interpretation No. 46 (or FIN 46), "Consolidation of Variable Interest Entities." FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or entitled to receive a majority of the entity's residual returns or both. The consoidation requirements of FIN 46 apply immediately to variable interest entities created after January 31, 2003. The consolidation requirements apply to older entities in the first fiscal year or interim period beginning after June 15, 2003. Certain of the disclosure requirements apply to all financial statements issued after January 31, 2003, regardless of when the variable interest entity was established. We do not have variable interest entities and do not expect the adoption of FIN 46 to have a material impact on our results of operations and financial position. Reclassifications - ----------------- Certain reclassifications have been made to the prior year financial statements to conform with the presentation in 2002. The provision for doubtful note receivable in 2001 was reclassified from income from discontinued operations to general and administrative expenses. A milestone payment received in 2001 was reclassified from royalty revenues to contract revenues. Revenues from license, research and development, and option fees were reclassified to contract revenues. Note 3 Cash Equivalents and Marketable Securities We consider all of our investments in debt and equity securities as available-for-sale and, accordingly, we have recorded these investments at fair value. Realized gains totaled $81,000, $84,000, and $6,000 for the years ended December 31, 2002, 2001 and 2000, respectively. There were no realized losses for the years ended December 31, 2002, 2001 and 2000. The cost of securities sold is based on the specific identification method. At December 31, 2002 and 2001, the amortized cost and estimated market value of investments in debt securities and cash are set forth in the tables below: December 31, 2002 (in thousands) ------------------------------------------------ Unrealized Unrealized Estimated Cost Gains Losses Market Value ------ ---------- ---------- ------------ Available-for-sale: Corporate debt securities $ 3,755 $ 14 $ (1) $ 3,768 Other debt securities 9,834 63 -- 9,897 ------ --- --- ------ Total available-for- sale 13,589 77 (1) 13,665 Cash 456 -- -- 456 ------ --- --- ------ Totals $14,045 $ 77 $ (1) $14,121 ====== === === ====== December 31, 2001 (in thousands) ------------------------------------------------ Unrealized Unrealized Estimated Cost Gains Losses Market Value ------ ---------- ---------- ------------ Available-for-sale: Corporate debt securities $10,071 $187 $ (1) $10,257 Other debt securities 8,980 52 -- 9,032 ------ --- --- ------ Total available-for- sale 19,051 239 (1) 19,289 Cash 205 -- -- 205 ------ --- --- ------ Totals $19,256 $239 $ (1) $19,494 ====== === === ====== The table below summarizes fair value disclosures at December 31 (in thousands): 2002 2001 ----------------------- ---------------------- Fair Fair Cost Value Cost Value ---- ---------- --------- ---------- Cash $ 456 $ 456 $ 205 $ 205 Cash equivalents 2,826 2,826 3,413 3,413 Marketable securities 10,763 10,839 15,638 15,876 ------ ------ ------ ------ Totals $14,045 $14,121 $19,256 $19,494 ====== ====== ====== ====== The cost and estimated fair value of available-for-sale debt securities as of December 31, 2002, by contractual maturity, consisted of the following (in thousands): Estimated Cost Market Value ----------- ------------ Available-for-sale: Due in one year or less $ 8,432 $ 8,444 Due after one or more years 5,157 5,221 ------ ------ Total available-for sale 13,589 13,665 Cash 456 456 ------ ------ Totals $14,045 $14,121 ====== ====== Note 4 Inventory The major components of inventory are as follows: December 31, (in thousands) --------------------------- 2002 2001 ---- ---- Raw materials $ 35 $ 27 Finished goods 33 33 ---- --- Total inventory $ 68 $ 61 ==== === Note 5 Property and Equipment Property and equipment consist of the following: December 31, (in thousands) --------------------------- 2002 2001 ---------- ---------- Leasehold improvements $ 1,359 $1,355 Furniture and equipment 3,651 3,263 ------ ------ Total property and equipment 5,010 4,618 Accumulated depreciation and amortization (3,374) (2,950) ------- ------ Property and equipment, net $ 1,636 $1,668 ======= ===== Depreciation expense amounted to $460,000, $400,000 and $375,000 for the years ended December 31, 2002, 2001 and 2000, respectively. Note 6 Accrued Expenses Accrued expenses consist of the following: December 31, (in thousands) ------------------ 2002 2001 ---- ---- Professional fees $ 178 $ 234 Accrued salaries 156 128 Accrued bonus and commission expenses 196 395 Clinical studies 205 450 Other 210 202 ----- ----- Total $ 945 $1,409 ===== ===== Note 7 Long-Term Debt In July 2000, we extinguished debt that was obtained in March 1999 with an original amount of $4 million and a fixed interest rate of 13.87%. Principal and interest payments were due in equal monthly installments over a period of forty-eight months commencing March 1999. Interest expense in 2000, prior to the extinguishment, was $244,000. In September 1995, we extinguished $2.5 million of Industrial Revenue Bonds through an "in-substance defeasance" transaction by placing approximately $2.5 million of United States government securities in an irrevocable trust to fund all future interest and principal payments. In accordance with the agreement, the investments held in the irrevocable trust shall be the exclusive source of all principal and interest payments and we have no liability for any shortfall in payments due. In addition, we have relinquished all rights with respect to the amounts held in the trust. The defeased debt balance outstanding of $2.5 million as of December 31, 2002 will be repaid on January 15, 2005 using the proceeds from the maturities of the United States government securities held in the irrevocable trust. The bond liability and related assets held in trust are not reflected in the accompanying consolidated balance sheets. Note 8 Commitments Total rental expense for facilities and equipment was $655,000, $516,000 and $587,000 for 2002, 2001 and 2000, respectively. Rental expense differs from cash payments under lease arrangements by $12,000, $148,000 and $62,000, in 2002, 2001 and 2000 as the Company's sales agreement to RP Scherer (see Note 11, "Discontinued Operations") allowed for RP Scherer to occupy a portion of the leased office facilities rent-free through January 25, 2002. The total amount of free rent provided to RP Scherer was accrued and charged to discontinued operations in 2000. Our future minimum lease payments under noncancelable operating leases for facilities as of December 31, 2002 are as follows (in thousands): Years Ending Minimum December 31, Payments ------------ ----------- 2003 $ 705 2004 602 2005 12 2006 7 ------ $1,326 ====== As part of the sale of our cosmeceutical and toiletry business to RP Scherer Corporation in July 2000, we guaranteed a minimum gross profit percentage on RP Scherer's sales of products to Ortho Neutrogena and Dermik. See Note 11 "Discontinued Operations". Note 9 Shareholders' Equity Shareholders Rights Plan - ------------------------ On August 19, 1996, the Board of Directors approved a Shareholders Rights Plan under which shareholders of record on September 3, 1996 received a dividend of one Preferred Stock purchase right ("Rights") for each share of common stock outstanding. The Rights were not exercisable until 10 business days after a person or group acquired 20% or more of the outstanding shares of common stock or announced a tender offer that could have resulted in a person or group beneficially owning 20% or more of the outstanding shares of common stock (an "Acquisition") of the Company. The Board of Directors approved an increase in threshold to 30% in December 1997. Each Right, should it become exercisable, will entitle the holder (other than acquirer) to purchase company stock at a discount. The Board of Directors may terminate the Rights plan or, under certain circumstances, redeem the rights. In the event of an Acquisition without the approval of the Board, each Right will entitle the registered holder, other than an acquirer and certain related parties, to buy at the Right's then current exercise price a number of shares of common stock with a market value equal to twice the exercise price. In addition, if at the time when there was a 30% shareholder, we were to be acquired by merger, shareholders with unexercised Rights could purchase common stock of the acquirer with a value of twice the exercise price of the Rights. The Board may redeem the Rights for $0.01 per Right at any time prior to Acquisition. Unless earlier redeemed, the Rights will expire on August 19, 2006. Stock-Based Compensation Plans - ------------------------------ We have two types of stock-based compensation plans, which consist of a stock purchase plan and two stock option plans. In 1997, our stockholders approved our 1997 Employee Stock Purchase Plan (the "Plan"). Under the Plan, we are authorized to issue up to 400,000 shares of common stock to our employees, nearly all of whom are eligible to participate. Under the terms of the Plan, employees can elect to have up to a maximum of 10 percent of their base earnings withheld to purchase our common stock. The purchase price of the stock is 85 percent of the lower of the closing prices for our common stock on: (i) the first trading day in the enrollment period, as defined in the Plan, in which the purchase is made, or (ii) the purchase date. The length of the enrollment period may not exceed a maximum of 24 months. Enrollment dates are the first business day of May and November and the first enrollment date was April 30, 1997. Approximately 42 percent of eligible employees participated in the Plan in 2002. Under the Plan, we issued 63,086 shares in 2002, 36,109 shares in 2001 and 36,825 shares in 2000. The weighted average fair value of purchase rights granted during 2002, 2001 and 2000 were $0.60, $1.47 and $1.90, respectively. The weighted average exercise price of the purchase rights exercised during 2002, 2001 and 2000 were $1.18, $1.82 and $3.05, respectively. We had 167,339 and 230,425 shares reserved for issuance under the stock purchase plan at December 31, 2002 and 2001, respectively. We have various stock option plans for employees, officers, directors and consultants. We grant stock options under the 2002 Stock Incentive Plan ("2002 Plan") and the Non-Qualified Stock Plan. The Company is authorized to issue up to 500,000 and 250,000 shares under the 2002 Plan and Non-Qualified Stock Plan, respectively. The options are granted at fair market value and expire no later than ten years from the date of grant. The options are exercisable in accordance with vesting schedules that generally provide for them to be fully exercisable four years after the date of grant. Any shares that are issuable upon exercise of options granted under the 2002 Plan and the Non-Qualified Stock Plan that expire or become unexercisable for any reason without having been exercised in full are available for future grant and issuance under the same stock option plan. In 2002, we granted options to purchase 12,500 shares of common stock to non- employees under the 2002 Plan. These options were granted in exchange for services to be rendered and vest over a period of two to four years. We recorded compensation expense related to option grants to non-employees of approximately $22,000 and $11,000 in 2002 and 2001, respectively, which represents the fair market value of the portion of the awards that vested during 2002 and 2001. The unvested shares held by consultants have been and will be revalued using the Black-Scholes option pricing model at the end of each accounting period. No stock options were granted to non-employees, and no stock options held by non-employees vested in 2000. The following table summarizes option activity for 2002, 2001 and 2000: 2002 2001 2000 ----------------- ------------------ -------------------- Weighted Weighted Weighted Average Average Average Exercise Exercise Exercise Shares Price Shares Price Shares Price ----------------- ------------------ -------------------- Outstanding at beginning of year 3,427,042 $5.25 3,910,177 $5.87 3,660,048 $6.30 Granted 316,000 1.87 467,000 2.51 507,000 3.12 Exercised -- -- -- -- -- -- Expired or Forfeited (835,905) 6.44 (950,135) 6.46 (256,871) 6.56 --------- --------- --------- Outstanding at end of year 2,907,137 4.54 3,427,042 5.25 3,910,177 5.87 ========= ========= ========= Options exercisable at year end 2,239,632 2,674,679 5.93 3,224,583 6.33 Shares available for future grant at year end 384,332 193,933 176,056 Weighted-average fair value of options granted during the year $1.76 $1.32 $1.70 The following table summarizes information about stock options outstanding at December 31, 2002: OPTIONS OUTSTANDING OPTIONS EXERCISABLE ---------------------------------- ------------------- Weighted Weighted Weighted Range of Average Average Average Exercise Number Contractual Exercise Number Exercise Prices Outstanding Life Price Exercisable Price - ----------- ----------- ----------- --------- ----------- --------- $1.00-$2.88 757,345 8.8 years $ 2.17 227,059 $ 2.39 $2.95-$4.63 780,500 6.5 3.74 649,531 3.86 $5.00-$5.88 768,250 2.0 5.42 762,000 5.42 $6.00-$10.25 601,042 3.8 7.42 601,042 7.42 --------- --------- $1.00-$10.25 2,907,137 5.4 $ 4.54 2,239,632 $ 5.20 ========= ========= We have adopted the disclosure only provisions of FAS 123 "Accounting for Stock-Based Compensation." Accordingly, except for stock options issued to non-employees and restricted stock awards to employees, no compensation cost has been recognized for the various stock option plans and stock purchase plan. The compensation cost that has been charged against income for the stock options issued to non-employees and restricted stock awards to employees and directors was $55,000, $123,000 and $180,000 for 2002, 2001 and 2000, respectively. The information regarding net income (loss) and earnings (loss) per share included in Note 2, "Summary of Significant Accounting Policies", prepared in accordance with FAS 123 has been determined as if we had accounted for our employee stock options and employee stock plan under the fair value method prescribed by FAS 123 and the earnings (loss) per share method under FAS 128. The fair value of options was estimated at the date of grant using a Black- Sholes option valuation model with the following weighted-average assumptions for 2002, 2001 and 2000, respectively: risk-free interest rates of 3.81%, 4.3% and 4.8%, dividend yields of 0%; volatility factors of the expected market price of our Common Stock of 114%, 62% and 58%, and a weighted-average expected life of the option of five years. The fair value of each award under the stock purchase plan was also estimated using the Black-Scholes option pricing model. For purchase rights granted in 2002, the multiple option approach with the following assumptions was used for expected terms of eighteen and twenty-four months: risk free interest rates of 1.7 percent and 3.2 percent; volatility factors of 69 percent and 68 percent; and dividend yield of zero. The purchase rights granted in 2001 were valued using the following assumptions for expected terms of eighteen and twenty-four months: risk free interest rates of 2.4 percent and 4.2 percent; volatility factors of 71 percent and 67 percent; and dividend yield of zero. The purchase rights granted in 2000 were valued using the following assumptions for expected terms of six, twelve, eighteen and twenty-four months: risk-free interest rate of 6.4 percent; volatility of 58 percent; and dividend yield of zero. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. For purposes of disclosures pursuant to FAS 123 as amended by FAS 148, the estimated fair value of options is amortized to expense over the options' vesting period. In 2001, we accelerated the vesting of options to purchase 40,000 shares of common stock held by the directors who departed the board as part of the refocusing of our company. As the exercise prices of these options exceeded our common stock's fair market value per share on the date of termination of services, we did not record compensation expense associated with these stock option accelerations. Also in 2001, we modified the 1992 Stock Option Plan to extend the exercise period of vested stock options upon employee termination, from up to 30 days after the date of termination to up to 90 days after the date of termination. We did not record compensation expense associated with this modification in 2002 and 2001, as none of the affected options were exercised during 2002 and 2001 and the number of stock options that may be affected in future periods was not estimable on the date of modification. Note 10 Earnings (Loss) Per Share The following table sets forth the computation of our basic and diluted loss per share (in thousands): 2002 2001 2000 ---- ---- ---- Loss from continuing operations $(4,166) $(5,929) $(3,758) ====== ====== ====== Net income (loss) (3,778) (2,514) 8,552 ====== ====== ====== Shares calculation: Weighted average shares outstanding - basic 20,409 20,276 20,179 Effect of dilutive securities: Stock options, employee stock purchase plan and stock to be issued to directors -- -- 33 Warrants -- -- 1 ------ ------ ------ Weighted average shares outstanding - diluted 20,409 20,276 20,213 ====== ====== ====== Basic income (loss) per common share: Loss from continuing operations $ (0.20) $ (0.29) $ (0.19) ====== ====== ====== Net income (loss) $ (0.19) $ (0.12) $ 0.42 ====== ====== ====== Diluted income (loss) per common share: Loss from continuing operations $ (0.20) $ (0.29) $ (0.19) ====== ====== ====== Net income (loss) $ (0.19) $ (0.12) $ 0.42 ====== ====== ====== The following options were outstanding during the periods presented, but were not included in the computation of diluted earnings per share since inclusion of these potentially dilutive securities would have been anti-dilutive for the periods presented (in thousands, except exercise prices): 2002 2001 2000 ---- ---- ---- Number outstanding 3,146 3,427 3,572 Range of exercise prices $1.00 - $10.25 $1.69 - $10.88 $3.88 - $15.00 Note 11 Discontinued Operations On July 25, 2000, we completed the sale of certain technology rights for our topical pharmaceuticals and cosmeceutical product lines and other assets ("cosmeceutical and toiletry business") to RP Scherer Corporation, a subsidiary of Cardinal Health, Inc. We received $25 million at closing and are entitled to receive further earnout amounts for the subsequent three years up to a maximum of $26.5 million, the amounts of which are dependent on the performance of the business sold. During the first two years of the earnout period, we received an aggregate of $3.8 million. The earnout is calculated based on gross profit earned by the business sold over a three- year period. The terms of the agreement with RP Scherer provide for an earnout of 20% to 60% of gross profit of the business sold over a threshold that increases each year. Each earnout year has a different minimum level of gross profit that should be achieved before any earnout income can be received. In addition to the minimum gross profit levels, each earnout period has three additional gross profit thresholds that correspond to a specific earnout percentage up to a maximum of 60%. Earnout thresholds for the third and final year are higher than the first two years. The cosmeceutical and toiletry business is reported as a discontinued operation for all periods presented in the accompanying Consolidated Statements of Operations. Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer's combined sales of products to Ortho Neutrogena and Dermik ("Gross Profit Guaranty"). The guaranty period commenced on July 1, 2000 and ends on the earlier of July 1, 2010 or the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equals or exceeds the guaranteed gross profit. Payments for the Gross Profit Guaranty aggregated $243,000 for the first two guaranty years. We expect the annual Gross Profit Guaranty payments to range from approximately $100,000 to $150,000 for the remainder of the guaranty period. As there is no minimum amount of Gross Profit Guaranty due, no accrual for the guaranty is estimable. The agreements with RP Scherer also included an indemnification for existing liabilities not assumed by RP Scherer and net realizable value of assets sold. The accompanying consolidated balance sheets as of December 31, 2002 and 2001 include a liability of $314,000 and $602,000, respectively, for an indemnification claim related to inventory deemed obsolete which was paid to RP Scherer in January 2003. Income from discontinued operations represents changes in estimates relating to the discontinued operations and consists of the following (in thousands): For the years ended December 31, 2002 December 31, 2001 ----------------- ----------------- Change in estimate for Kligman lawsuit settlement $ -- $(94) Provision for doubtful accounts and note receivable (28) -- Recovery of doubtful accounts receivables -- 220 Change in estimate for professional fees, severance costs and guarantees 135 74 Change in estimate of provision for income taxes and tax refunds 65 325 --- --- Total change in estimate $172 $525 === === Revenues relating to the discontinued operation totaled $0, $0 and $10,199,000 for the years ended December 31, 2002, 2001 and 2000, respectively. "Gain on disposal of discontinued operations" in the accompanying Consolidated Statement of Operations for the year ended December 31, 2001 is reported net of allowances for claims made by RP Scherer, mostly due to an indemnification claim relating to inventory deemed obsolete, pursuant to the agreement. "Gain on disposal of discontinued operations" for the year ended December 31, 2000 is reported net of a provision for income taxes of $450,000. The following table sets forth the Company's basic and diluted income per common share from discontinued operations excluding the gain on sale for the years ended December 31, 2002, 2001 and 2000: For the years ended December 31, -------------------------------- 2002 2001 2000 ---- ---- ---- Basic income per common share from discontinued operations $0.01 $0.03 $0.06 Diluted income per common share from discontinued operations $0.01 $0.03 $0.06 As of December 31, 2002, net assets relating to the discontinued operation include trade receivables of $195,000 and a provision for doubtful accounts and note receivable of $28,000. Liabilities related to the discontinued operation in the amount of $514,000 include severance costs and accruals for indemnification claims related to inventory and gross profit guarantees. These liabilities are reported as accrued disposition costs in the accompanying consolidated balance sheets. Cash used in discontinued operations primarily relates to payments of severance costs to former employees who were terminated as a result of the sale of the cosmeceutical and toiletry business. A total of 56 positions, primarily in the manufacturing, marketing and research and development departments and associated general and administrative staff, were eliminated as a result of the sale. During the year ended December 31, 2000, we recorded severance charges related to salaries and benefits in gain on disposition of discontinued operations. The total amount of severance- related charges was approximately $3,685,000, of which approximately $3,540,000 has been paid to date, including $495,000 in the current year. Approximately $145,000 remains accrued as of December 31, 2002. The accrued severance of approximately $145,000 is expected to be paid by July 31, 2003. Note 12 Defined Contribution Plan We have a defined contribution plan covering substantially all of our employees. In the past three calendar years, we made matching cash contributions equal to 50% of each participant's contribution during the plan year up to a maximum amount equal to the lesser of 3% of each participant's annual compensation or $5,500, $5,250 and $5,100 for 2002, 2001 and 2000 , respectively, and such amounts were recorded as expense in the corresponding years. We may also contribute additional discretionary amounts to the defined contribution plan as we may determine. For the years ended December 31, 2002, 2001 and 2000, we contributed to the plan approximately $79,000, $56,000 and $106,000, respectively. No discretionary contributions have been made to the plan since its inception. Note 13 Income Taxes There is no provision for income taxes because we have incurred operating losses. Deferred income taxes reflect the net tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets are as follows (in thousands): December 31, ------------------------ 2002 2001 ---- ---- Deferred Tax Assets: Net operating loss carryforwards $ 24,000 $22,300 Research credits 2,000 2,400 Capitalized research expenses 300 200 Other 1,000 1,400 ------- ------- Total deferred tax assets 27,300 26,300 Valuation allowance (27,300) (26,300) ------- ------ Net deferred tax assets -- -- ======= ====== Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased (decreased) by $1,000,000, $289,500, and ($604,500) during 2002, 2001, and 2000, respectively. Deferred tax assets related to carryforwards at December 31, 2002 include approximately $2,800,000 associated with stock option activity for which any subsequently recognized tax benefits will be credited directly to stockholders' equity. As of December 31, 2002, we had net operating loss carryforwards for federal income tax purposes of approximately $70,000,000 which expire in the years 2003 through 2022 and federal research and development tax credits of approximately $1,200,000 which expire in the years 2003 through 2022. As of December 31, 2001, we had net operting loss carryforwards for state income tax purposes of approximately $2,000,000 which expire in the years 2004 through 2013 and state research and development tax credits of approximately $1,100,000 which do not expire. We also have federal alternative minimum tax carryforwards of approximately $164,000 which do not expire. Utilization of our net operating loss and credit carryforwards may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of the net operating loss and credits before utilization. Note 14 Significant Agreements Ortho Neutrogena Corporation - ---------------------------- In May 1992, we entered into development and licensing and investment agreements with Ortho Neutrogena (formerly Ortho-McNeil Pharmaceutical Corporation) ("Ortho") for the development of retinoid products. The first product is a Microsponge system entrapment of tretinoin (trans-retinoic acid or "t-RA"), a prescription acne drug product for which FDA approval was received in February 1997. A second product licensed to Ortho is a Microsponge entrapment of a retinoid to be used for the treatment of photodamaged skin. In February 1995, we received $750,000 in prepaid royalties and an additional $750,000 as a milestone payment on the submission to the FDA of its New Drug Application ("NDA") for the tretinoin prescription acne treatment. The milestone payment was recognized as revenue upon receipt. The prepaid royalties of $750,000 were recorded as deferred revenue. In February 1997, upon receipt of approval from the FDA to market Retin-A Micro(R) (tretinoin gel) microsphere for the treatment of acne, we received $3 million from Ortho, $1.5 million of which was a milestone payment that was recognized as revenue in 1997 and $1.5 million of which was prepaid royalties that was recorded as deferred revenue. As of December 31, 2002, $595,000 of these payments remained in deferred revenues. Ortho pays us a royalty on product sales. In accordance with the licensing agreement, 25% of the royalties we earn is applied against deferred revenues after certain annual minimum royalty payments are met. Should these minimums not be achieved, Ortho would lose its exclusivity and we would regain marketing rights to the retinoid products. Dermik - ------ In March 1992, we restructured a 1989 joint venture agreement with Dermik, an Aventis company. As part of the agreement, Aventis received certain exclusive marketing rights. Product applications include a 5-FU treatment for actinic keratoses. In 1998, this agreement was amended to give Dermik an exclusive worldwide license to Microsponge-entrapped 5-FU and to increase the royalty payable to us from 5% to 10%. In 1999, Dermik filed an NDA for this product and expanded its agreement with us to cover two additional indications, in return for milestone payments and royalties upon successful development. We received $500,000 on the execution of this amendment representing a milestone payment of $250,000 and prepaid royalties of $250,000. In 2000, Dermik received FDA marketing clearance for the product, which was launched under the trade name Carac(TM) in 2001 and we received a milestone payment of $50,000. In accordance with the agreement, the prepaid royalties were to be creditable against further royalties in at least two indications containing the Licensed Product. During 2002, Dermik decided not to pursue the additional indications covered by the 1999 amendment, thereby forfeiting its prepaid royalties. The accompanying Consolidated Statements of Operations include $237,000 in earned contract revenues in 2002. Dermik's exclusivity will continue as long as annual minimum royalty payments are made, governed by the life of our applicable patents. Note 15 Subsequent Event On February 13, 2002 (the "closing date"), we completed the sale of the assets of our wholly-owned subsidiary, APS Analytical Standards, Inc. to GFS Chemicals, Inc., a private company based in Columbus, Ohio. We received $2.1 million in cash on the closing date and are entitled to receive royalties on sales varying from 5% to 15% for five years following the closing, with guaranteed minimum annual royalty payments. The net carrying amount of the APS Analytical Standards subsidiary consists of the following (in thousands): December 31, 2002 ----------------- Assets: Cash $ 78 Accounts Receivable, net 165 Inventory 68 Other Assets -- Property and Equipment 10 --- Total Assets $321 --- Liabilties: Accounts Payable $ 18 Accrued Expenses 54 --- Total Liabilities 72 --- Net Carrying Amount $249 === Note 16 Quarterly Results of Operations (Unaudited) The following table presents summarized results of operations for each of our quarters in the years ended December 31, 2002 and 2001.
