MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion of the financial condition and results of operations of the Company should be read in conjunction with the Financial Statements and the related Notes thereto included elsewhere in this Form 10-K. Except for historical information contained herein, the discussion in this section contains forwardlooking statements, including, without limitation, statements regarding timing and results of clinical trials, the establishment of corporate partnering arrangements, the anticipated commercial introduction of the Company's products and the timing of the Company's cash requirements. These forward- looking statements involve certain risks and uncertainties that could cause actual results to differ materially from those in such forward-looking statements. Potential risks and uncertainties include, without limitation, those mentioned in this report and in particular, the factors described in Part II, under the heading "Risk Factors". <PAGE 3> Overview Since its inception in 1991, Aradigm has been engaged in the development of pulmonary drug delivery systems. As of December 31, 1997, the Company had an accumulated deficit of $35.8 million. The Company has been unprofitable since inception and expects to incur additional operating losses over at least the next several years as the Company's research and development efforts, preclinical and clinical testing activities and manufacturing scale-up efforts expand and as the Company plans and builds its late-stage clinical and early commercial production capabilities. To date, Aradigm has not sold any products and does not anticipate receiving significant revenue from products in 1998. The sources of working capital have been equity financing, financing of equipment acquisitions, interest earned on investments of cash and revenues from research and feasibility agreements and development contracts. The Company has performed and has been compensated for expenses incurred during initial feasibility work and for work performed under collaborative agreements. Once feasibility is demonstrated, the Company's strategy is to enter into development contracts with pharmaceutical corporate partners. These partners will pay for research and development expenses and will make additional payments to the Company as it achieves certain significant milestones. The Company also expects to receive royalties from its corporate partners based on revenues received from product sales and to receive revenue from the manufacturing of unit dose packets and hand-held devices. However, there can be no assurance that the Company will be able to generate sufficient product or contract research revenue to become profitable or to sustain profitability. <PAGE 4> Results of Operations Years Ended December 31, 1997, 1996 and 1995 Contract and License Revenue. The Company reported revenues from contracts and license fees of $3.7 million in 1997 compared to $730,000 in 1996 and $155,000 in 1995. The increase in 1997 revenue was due primarily to a development and commercialization agreement that was executed with SmithKline Beecham in September 1997 to develop and commercialize a pulmonary delivery system for providing breakthrough pain relief using narcotic analgesics. Under the terms of the agreement, Aradigm could receive up to approximately $30 million in milestones and development payments by the time the first product is commercialized. Additional milestones and development costs would be paid if SmithKline Beecham and Aradigm decided to develop additional narcotic analgesics for delivery with the AERx Pain Management System. Included in 1996 revenues were $500,000 of license fees from a human clinical feasibility testing agreement and $230,000 of contract research revenues. 1995 revenues were derived entirely from contract research agreements. Costs of development contract research revenue approximate such revenue and are included in research and development expense. <PAGE 5> Research and Development Expenses. Research and development expenses have increased each year since the Company's inception; these expenses were $12.7 million in 1997 compared to $8.0 million in 1996 and $3.4 million in 1995. Research and development expenses in 1997, 1996 and 1995 represented 65%, 73% and 60% of total expenses, respectively. Research and development expenses in 1997 increased by 60% over 1996, attributable primarily to hiring of additional scientific personnel and expenses associated with the expansion of research and development efforts on the AERx system. Research and development expenses in 1996 increased by 132% over 1995, similarly attributable to hiring additional scientific personnel, increased costs associated with the expansion of research and development efforts on the AERx and SmartMist systems and initiation of additional clinical testing of the AERx and SmartMist systems. These expenses represent proprietary research expenses as well as the costs related to contract research revenue and include salaries and benefits of scientific and development personnel, laboratory supplies, consulting services and the expenses associated with the development of manufacturing processes. The Company expects research and development spending to increase significantly over the next few years as the Company continues to expand its development activities under collaborative agreements, and plans, builds and scales up a late stage clinical and early stage commercial manufacturing facility. <PAGE 6> General and Administrative Expenses. General and administrative expenses were $6.7 million in 1997 compared to $3.0 million in 1996 and $2.3 million in 1995. General and administrative expenses increased by 128% in 1997 compared to 1996 and 27% in 1996 compared to 1995, attributable primarily to support of the Company's increased research efforts, additional facilities expense, administrative staffing, business development and marketing activities. The Company expects to incur greater general and administrative expenses in the future as it expands its research, development and manufacturing activities and increases its efforts to develop collaborative relationships with corporate partners. Interest Income. Interest income increased to $1.3 million in 1997 from $1.2 million in 1996 and $206,000 in 1995. Interest income in 1997 was consistent with that in 1996 due to similar average cash balances during those two years. Interest income increased significantly in 1996 compared to 1995 primarily due to increased average cash balances in 1996 resulting from the sales of preferred stock in December 1995 and common stock in June 1996 in conjunction with the Company's initial public offering. Interest Expense. Interest expense was $234,000 in 1997 compared to $52,000 in 1996 and $20,000 in 1995. These increases resulted primarily from higher outstanding capital lease and equipment loan balances under the Company's equipment lines of credit. Net Operating Loss Tax Carryforwards. As of December 31, 1997, the Company had federal net operating loss tax carryforwards of approximately $35.0 million. These carryforwards will expire beginning in the year 2006. Utilization of net operating loss carryforwards may be subject to substantial annual limitation due to the ownership change limitation provided for by the Internal Revenue Code of 1986. The annual limitation may result in the expiration of net operating loss carryforwards before utilization. <PAGE 7> Liquidity and Capital Resources The Company has financed its operations since inception primarily through private placements and public offerings of its capital stock, proceeds from financings of equipment acquisitions, contract research revenue and interest earned on investments. As of December 31, 1997, the Company had received approximately $54.0 million in net proceeds from sales of its capital stock. The Company also has a $5.0 million equipment line of credit, of which approximately $2.9 million remains available for purchases through September 1998. As of December 31, 1997, the Company had cash, cash equivalents and short-term investments of approximately $24.3 million. Net cash used in operating activities in 1997, was $7.8 million compared to $7.1 million in 1996. This increase resulted primarily from an increase in net loss of $5.6 million and increases in current assets, largely offset by net increases in accrued liabilities and deferred revenue. Net cash used in operating activities in 1996 was $7.1 million compared to $5.2 million in 1995. This increase resulted primarily from an increase in net loss of $3.6 million partially offset by an increase in accrued liabilities and accounts payable reduced by a net increase in current assets. Net cash used in investing activities in 1997 was $463,000 compared to $11.9 million in 1996. This resulted primarily from the Company's receipt of net proceeds from investment maturities partially offset by expenditures made for capital equipment. Net cash used in investing activities in 1996 was $11.9 million compared to $535,000 in 1995. The increase resulted primarily from the Company's net purchase of investments and additional capital expenditures. <PAGE 8> Net cash provided by financing activities in 1997 was $6.4 million primarily from the receipt of proceeds from equipment loans and issuances of common stock partially offset by repayment of capital lease obligations. Net cash provided by financing activities in 1996 of $24.3 million was due primarily to the receipt of net proceeds from the Company's initial public offering. Net cash provided by financing activities for 1995 was $11.7 million, primarily a result of $11.6 million in net proceeds from the issuance of preferred stock. The development of the Company's technology and proposed products will require a commitment of substantial funds to conduct the costly and timeconsuming research and preclinical and clinical testing activities necessary to develop and refine such technology and proposed products and to bring any such products to market. The Company's future capital requirements will depend on many factors, including continued progress in the research and development of the Company's technology and drug delivery systems, the ability of the Company to establish and maintain favorable collaborative arrangements with others, progress with preclinical studies and clinical trials, the time and costs involved in obtaining regulatory approvals, the cost of development and the rate of scale up of the Company's production technologies, the cost involved in preparing, filing, prosecuting maintaining and enforcing patent claims and the need to acquire licenses or other rights to new technology. <PAGE 9> The Company expects that its existing capital resources, committed funding from its existing corporate partnership with SmithKline Beecham and projected interest income will enable the Company to maintain current and planned operations through at least 1998. However, there can be no assurance that the Company will not need to raise substantial additional capital to fund its operations prior to such time. There can be no assurance that additional financing will be available on acceptable terms or at all. The Company's cash requirements, however, may vary materially from those now planned because of results of research and development efforts, including capital expenditures and funding preclinical and clinical trials, manufacturing scaleup in connection with the commercialization of the SmartMist system, and manufacturing capacity for preclinical, clinical and full scale manufacturing requirements of the AERx system. The Company may seek additional funding through collaborations or through public or private equity or debt financings. However, there cannot be any assurance that additional financing can be obtained on acceptable terms, or at all. If additional funds are raised by issuing equity securities, dilution to shareholders may result. If adequate funds are not available, the Company may be required to delay, to reduce the scope of, or to eliminate one or more of its research and development programs, or to obtain funds through arrangements with collaborative partners or other sources that may require the Company to relinquish rights to certain of its technologies or products that the Company would not otherwise relinquish. <PAGE 10> As the year 2000 approaches, an issue impacting all companies has emerged regarding how existing application software programs and operating systems can accommodate this date value. In brief, many existing application software products in the marketplace were designed to accommodate only a two digit date position which represents the year (e.g., "95" is stored on the system and represents the year 1995). As a result, the year 1999 (i.e., "99") could be the maximum date value systems will be able to accurately process. Management is in the process of working with its software vendors to assure that the Company is prepared for the year 2000. Management does not anticipate that the Company will incur significant operating expenses or be required to invest heavily in computer system improvements to be year 2000 compliant. Risk Factors Except for historical information contained herein, the discussion in this section contains forward-looking statements, including, without limitation, statements regarding timing and results of clinical trials, the establishment of corporate partnering arrangements, the anticipated commercial introduction of the Company's products and the timing of the Company's cash requirements. These forward- looking statements involve certain risks and uncertainties that could cause actual results to differ materially from those in such forward- looking statements. <PAGE 11> Early Stage of Company Aradigm, incorporated in January 1991, is in an early stage of development, has a limited history of operations and has generated only limited revenues to date. The Company has only one product, the SmartMist Respiratory Management System, cleared for commercial sale, and virtually all of its potential products are in an early stage of research or development. There can be no assurance that the Company's research and development efforts will be successful, that any potential products will be proven safe and effective, that regulatory clearance or approval for the sale of any of its potential products will be obtained or that the SmartMist system or any of the Company's potential products can be manufactured in commercial quantities or at an acceptable cost or marketed successfully. History of Losses; Anticipated Future Losses The Company has not been profitable since inception and, through December 31, 1997, has incurred a cumulative deficit of approximately $35.8 million. The Company expects to continue to incur substantial losses over at least the next several years as the Company's research and development efforts, preclinical and clinical testing activities, marketing and manufacturing scale-up efforts expand and as the Company plans and builds its late stage clinical and early commercial production capabilities. To achieve and sustain profitable operations, the Company, alone or with others, must successfully market and sell the SmartMist Respiratory Management System and develop, obtain regulatory approval for, manufacture, introduce, market and sell products utilizing the Company's AERx technologies. There can be no assurance that the Company can generate sufficient product revenue to become profitable or to sustain profitability. <PAGE 12> Uncertainty of Successful Product Development The Company's AERx systems are at an early stage of development and are being tested using patient operated prototypes. The AERx systems will require substantial additional development, preclinical and clinical testing and investment before they can be commercialized. To further develop its AERx systems, the Company must address many engineering and design issues, including ensuring that the device has the ability to deliver a reproducible amount of drug into the bloodstream and can be manufactured successfully as a hand-held system. No assurance can be made that the Company will be successful in addressing these design, engineering and manufacturing issues. Additionally, the Company may need to formulate and will need to package drugs for delivery by its AERx systems. There can be no assurance that the Company will be able to successfully formulate and package such drugs. The Company will need to demonstrate that drugs delivered by its AERx systems remain safe and efficacious and that over time and under differing storage conditions, such drugs will not be subject to physical or chemical instability or other problems that would prohibit the AERx systems from being commercially viable. While development efforts are at different stages for different products, there can be no assurance that the Company will be successful in any of its product development efforts, or that the Company will not abandon some or all of its proposed products. Failure by the Company to successfully develop its potential products in a timely manner would have a material adverse effect on the Company. <PAGE 13> Uncertainty of Successful Product Commercialization The Company's success in commercializing its products will be dependent upon many factors, including acceptance by health care professionals and patients. Acceptance of the Company's products will largely depend on demonstrating that the Company's products are competitive with alternate delivery systems with respect to safety, efficacy, ease of use and price. The Company believes that market acceptance of its SmartMist system will depend largely upon health care professionals and third-party payors determining that the SmartMist system offers medical and economic benefits over existing asthma therapies. In addition, the SmartMist system is specifically designed for the canisters currently used by some of the leading manufacturers of MDIs. If, among other things, manufacturers decide to change the dimensions of their canisters, the Company could be adversely affected. Moreover, MDIs use chlorofluorocarbons("CFCs") as a propellant for the medication. The Company is aware of initiatives and international agreements to ban CFCs, which could have an adverse effect on the Company. In order to commercialize the SmartMist system, the company is pursuing collaborations with pharmaceutical firms, disease management companies and managed care organizations in order to develop the market for this product and to realize its potential as part of a broader disease management program. There can be no assurance that the SmartMist system or the Company's products in development will prove competitive or that the Company will be successful in taking products from their current state of development to commercial introduction or success. Failure by the Company to successfully commercialize its potential products in a timely manner would have a material adverse effect on the Company. <PAGE 14> Dependence Upon Collaborative Partners and Need for Additional Collaborative Partners The Company's commercialization strategy is dependent, in part, on the Company's ability to enter into agreements with collaborative partners. The Company's ability to successfully develop and commercialize its first AERx system, the AERx Pain Management System, is dependent on the Company's corporate partnership with SmithKline Beecham. SmithKline Beecham has agreed to undertake certain collaborative activities with the Company, fund research and development activities with the Company, make certain payments to the Company upon achievement of certain milestones and pay royalties to the Company if and when a product is commercialized. If SmithKline Beecham fails to conduct these collaborative activities in a timely manner or at all, the preclinical or clinical development or commercialization of the AERx Pain Management System will be delayed. In addition, the agreement may be terminated by SmithKline Beecham and there can be no assurance that development and milestone payments will be received. Should the Company fail to receive development funds or achieve milestones set forth in the agreement, or should SmithKline Beecham breach or terminate the agreement, the Company's business, financial condition and results of operations would be materially adversely affected. <PAGE 15> The Company will need to enter into additional agreements with corporate partners to conduct the clinical trials, manufacturing, marketing and sales necessary to commercialize its other potential products. In addition, the Company's ability to apply the AERx system to any proprietary drugs, including new drugs, biotechnology drugs or established drugs in proprietary formulations, will depend on the Company's ability to establish and maintain corporate partnerships or other collaborative arrangements with the holders of proprietary rights to such drugs. There can be no assurance that the Company will be able to establish such additional corporate partnerships or collaborative arrangements on favorable terms or at all, or that its existing or any future corporate partnerships or collaborative arrangements will be successful. In addition, there can be no assurance that existing or future corporate partners or collaborators will not pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including the Company's competitors. There can be no assurance that disputes will not arise in the future with the Company's existing or future corporate partners or collaborators, and any such disagreements could lead to delays in the research, development or commercialization of any potential products or result in litigation or arbitration which would be time consuming and expensive. Should any corporate partner or collaborator fail to develop or commercialize successfully any product to which it has obtained rights from the Company, the Company's business, financial condition and results of operations may be materially adversely affected. <PAGE 16> Limited Manufacturing Experience The Company has only limited experience in manufacturing. To date, the Company has scaled-up its manufacturing capabilities to support the product launch of the SmartMist system. In the event the SmartMist system achieves market acceptance, the Company will need to further increase its current manufacturing capacity. In addition, the Company is in the process of increasing the production of disposable drug packets for the AERx system for later stage clinical trials. The Company anticipates making significant expenditures to attempt to provide for the high volume manufacturing required for multiple AERx products, if such products are successfully developed. There can be no assurance that manufacturing and quality control problems will not arise as the Company attempts to scale-up, or that any such scaleup can be achieved in a timely manner or at a commercially reasonable cost. Any failure to surmount such problems could delay or prevent late stage clinical testing and commercialization of the Company's products. The Company's manufacturing facilities and those of its contract manufacturers will be subject to periodic regulatory inspections by the FDA and other federal and state regulatory agencies and such facilities must comply with good manufacturing practice ("GMP") requirements of the FDA. There can be no assurance the Company will satisfy such regulatory requirements and any failure to satisfy GMP and other requirements could have a material adverse effect on the Company. <PAGE 17> The Company uses contract manufacturers to produce key components, assemblies and subassemblies for its SmartMist devices and intends to use contract manufacturers in a similar way in connection with clinical and commercial manufacturing of its AERx devices. There can be no assurance that Aradigm will be able to enter into or maintain satisfactory contract manufacturing arrangements. Certain components of Aradigm's current and potential products are or will be available initially only from single sources. While the Company has contingency plans for alternate suppliers, there can be no assurance that the Company could find alternate suppliers for such components. Even if new suppliers are secured, there can be no assurance that this would not significantly reduce or eliminate the Company's ability to supply product during any transition. A delay of or interruption in production could have a material adverse effect on the Company's business, financial condition and results of operations. Future Capital Needs; Uncertainty of Additional Funding The Company's operations to date have consumed substantial and increasing amounts of cash. The negative cash flow from operations is expected to continue in the foreseeable future. The development of the Company's technology and proposed products will require a commitment of substantial funds. In addition, costly and time consuming research and preclinical and clinical testing activities must be conducted to develop, refine and commercialize such technology and proposed products. The Company's future capital requirements will depend on many factors, including continued progress in the research and development of the Company's technology and drug delivery systems, the ability of the Company to establish and maintain favorable collaborative arrangements with others, progress with preclinical studies and clinical trials, the time and costs involved in obtaining regulatory approvals, the cost of development and the rate of scaleup of the Company's production technologies, the cost involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and the need to acquire licenses or other rights to new technology. <PAGE 18> The Company has financed its operations since inception primarily through private placements and public offerings of its capital stock, proceeds from financings of equipment acquisitions, contract research revenue and interest earned on investments. The Company anticipates that its existing resources, anticipated payments from its existing corporate partners and projected interest income, will enable the Company to maintain its current and planned operations through 1998. However, there can be no assurance that the Company will not need to raise substantial additional capital to fund its operations prior to such time. There can be no assurance that additional financing will be available on acceptable terms or at all. If additional funds are raised by issuing equity securities, substantial dilution to shareholders may result. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate one or more of its research or development programs or obtain funds through arrangements with collaborative partners or others that may require the Company to relinquish rights to certain of its technologies, product candidates or products that the Company would not otherwise relinquish. <PAGE 19> Dependence Upon Proprietary Technology; Uncertainty of Patents and Proprietary Technology The field of aerosolized drug delivery is crowded and a substantial number of patents have been issued in this field. Competitors and institutions may have applied for other patents and may obtain additional patents and proprietary rights relating to products or processes competitive with those of the Company. Patents or other publications may hinder or prevent the Company from obtaining patent protection being sought or draw into question the validity of patents already issued to the Company. In addition, patents issued to others might provide competitors with the ability to prevent the Company from making its products or carrying out processes necessary for use of its products. The Company may not be able to obtain a license under any such patent and may thereby be prevented from making products or carrying out processes which are important or essential to the business of the Company. Although issued patents are presumed valid under federal law, none of the patents of the Company has been challenged in litigation. There can be no assurance that any of such patents will be found valid if challenged. There also can be no assurance that any of the applications will issue or if issued will later be found valid if challenged. Further, there can be no assurance that any issued patents or applications which might later issue as patents will provide the Company with a degree of market exclusivity sufficient for the Company to profitably compete against its competitors. Pending United States applications are maintained in secret until they are issued as patents and as such can not be searched by the Company. There may be pending applications which will later issue as patents which will create infringement issues for the Company. Further, patents already issued to the Company or applications of the Company which are pending may become involved in interferences that could be resolved in favor of competitors of the Company and involve the expenditure of substantial financial and human resources of the Company. <PAGE 20> Company policy is to require its officers, employees, consultants and advisors to execute proprietary information and invention assignment agreements upon commencement of their relationships with the Company. There can be no assurance, however, that these agreements will provide meaningful protection for the Company's inventions, trade secrets or other proprietary information in the event of unauthorized use or disclosure of such information. Violations of such agreements are difficult to police. See "Business Intellectual Property and Other Proprietary Rights." Government Regulation; Uncertainty with Preclinical and Clinical Testing All medical devices and new drugs, including the Company's products under development, are subject to extensive and rigorous regulation by the federal government, principally the FDA, and by state and local governments. Such regulations govern the development, testing, manufacture, labeling, storage, premarket clearance or approval, advertising, promotion, sale and distribution of such products. If medical devices or drug products are marketed abroad, they also are subject to regulation by foreign governments. The regulatory process for obtaining FDA premarket clearances or approvals for medical devices and drug products is generally lengthy, expensive and uncertain. Securing FDA marketing clearances and approvals often requires the submission of extensive clinical data and supporting information to the FDA. Product clearances and approvals, if granted, can be withdrawn for failure to comply with regulatory requirements or upon the occurrence of unforeseen problems following initial marketing. <PAGE 21> There can be no assurance that the Company will be able to obtain necessary regulatory clearances or approvals on a timely basis, if at all, for any of its products under development, and delays in receipt or failure to receive such clearances or approvals or failure to comply with existing or future regulatory requirements could have a material adverse effect on the Company. Moreover, regulatory clearances or approvals for products such as medical devices and new drugs, even if granted, may include significant limitations on the uses for which such products may be marketed. Certain changes to marketed medical devices and new drugs are subject to additional FDA review and clearance or approval. There can be no assurance that any clearances or approvals that are required, once obtained, will not be withdrawn or that compliance with other regulatory requirements can be maintained. Further, failure to comply with applicable FDA and other regulatory requirements can result in sanctions being imposed on the Company or the manufacturers of its products, including warning letters, fines, product recalls or seizures, injunctions, refusals to permit products to be imported into or exported out of the United States, refusals of FDA to grant premarket clearance or premarket approval of medical devices and drugs or to allow the Company to enter into government supply contracts, withdrawals of previously approved marketing applications and criminal prosecutions. The Company received 510(k) clearance from the FDA in 1996 for the SmartMist system. The Company has made modifications to the SmartMist system since receiving clearance, which the Company believes do not require the submission of new 510(k) notifications to the FDA. There can be no assurance, however, that the FDA would agree with any of the Company's determinations not to submit a new 510(k) notice for any of these changes or would not require the Company to submit a new 510(k) notice for any of the changes made to the device. If the FDA requires the Company to submit a new 510(k) notice for any modification to the SmartMist system, the Company may be prohibited from marketing the modified device until the 510(k) notice is cleared by the FDA, which could have a material adverse effect on the Company. The Company may also be subject to certain user fees that the FDA is authorized to collect under the Prescription Drug User Fees Act of 1992 for certain drugs, including insulin and morphine. This act expired on September 30, 1997, and legislation to reauthorize it has been passed by the House and Senate. It must be reconciled in a House-Senate conference and signed by the President to become law. <PAGE 22> Before the Company can file for regulatory approvals for the commercial sale of the Company's potential AERx products, the FDA will require extensive preclinical and clinical testing to demonstrate the safety and efficacy of such potential products. To date, the Company has tested an early prototype patient-operated version of the AERx Pain Management System with morphine on a limited number of healthy volunteers in Phase I clinical trials in the United States. Failure of the Company to progress to more advanced clinical trials would have a material adverse effect on the Company. There can be no assurance that the Company will be able to manufacture sufficient quantities of the disposable unit-dose packets to support any future clinical trials of the AERx system, or that the design requirements of the AERx system will make it feasible for development beyond the prototype currently being used. The timing of completion of clinical trials is dependent upon, among other factors, the enrollment of patients. Patient recruitment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the study and the existence of competitive clinical trials. Delays in planned patient enrollment in the Company's current trials or future clinical trials may result in increased costs, program delays or both, which could have a material adverse effect on the Company. <PAGE 23> The Company also is developing applications of its AERx system for the delivery of insulin and other compounds. These applications are in an early stage of development and the regulatory requirements associated with obtaining the necessary marketing approvals from the FDA and other regulatory agencies are not known. There can be no assurance that these applications of the AERx system will prove to be viable or that any necessary regulatory approvals will be obtained in a timely manner, if at all. Although the Company believes the data regarding the Company's potential products is encouraging, the results of initial preclinical and clinical testing of the products under development by the Company are not necessarily predictive of results that will be obtained from subsequent or more extensive preclinical and clinical testing. Furthermore, there can be no assurance that clinical trials of products under development will demonstrate the safety and efficacy of such products at all or to the extent necessary to obtain regulatory approvals. Companies in the medical device, pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to demonstrate adequately the safety and efficacy of a therapeutic product under development could delay or prevent regulatory approval of the product and would have a material adverse effect on the Company. <PAGE 24> In addition, due to limited experience with chronic administration of drugs delivered via the lung for systemic effect, the FDA may require clinical data to demonstrate that such chronic administration is safe. There can be no assurance that the Company will be able to present such data in a timely manner, or at all. The FDA and other regulatory agency requirements for manufacturing, product testing and marketing can vary depending upon whether the product is a medical device or a drug. Manufacturers of medical devices and drugs also are required to comply with the applicable GMP requirements, which relate to product testing and quality assurance as well as the corresponding maintenance of records and documentation. There can be no assurance that the Company will be able to comply with the applicable GMP and other FDA regulatory requirements as it scales up its manufacturing operations. Such failure could have a material adverse effect on the Company. In addition, in order for the Company to market its products in Europe and in certain other foreign jurisdictions, the Company and its distributors and agents must obtain required regulatory approvals and clearances and otherwise comply with extensive regulations regarding safety and quality. These regulations, including the requirements for approvals or clearance to market and the time required for regulatory review, vary from country to country. There can be no assurance that the Company will obtain regulatory approvals in such countries or that it will not be required to incur significant costs in obtaining or maintaining its foreign regulatory approvals. Delays in receipt of approvals to market the Company's products, failure to receive these approvals, or future loss of previously received approvals could have a material adverse effect on the Company's business, financial condition and results of operations. <PAGE 25> Because the Company's AERx Pain Management System clinical studies involve morphine, the Company is registered with the Drug Enforcement Agency ("DEA") and its facilities are subject to inspection and DEA export, import, security and production quota requirements. There can be no assurance that the Company will not be required to incur significant costs to comply with DEA regulations in the future or that such regulations will not have a material adverse effect on the Company. Highly Competitive Markets; Risk of Alternative Therapies The medical device, pharmaceutical and biotechnology industries are highly competitive and rapidly evolving. The Company's success will depend on its ability to successfully develop products and technologies for pulmonary drug delivery. If a competing company were to develop or acquire rights to a better pulmonary delivery device, the Company could be materially and adversely affected. The Company is in competition with pharmaceutical, biotechnology and drug delivery companies and other entities engaged in the development of alternative drug delivery systems or new drug research and testing, as well as with entities producing and developing injectable drugs. The Company is aware of a number of companies currently seeking to develop new products and non-invasive alternatives to injectable drug delivery, including oral, intranasal and transdermal delivery systems and colonic absorption systems. The Company also is aware of other companies currently engaged in the development and commercialization of pulmonary drug delivery systems and enhanced injectable drug delivery systems. Many of the Company's competitors have greater research and development capabilities, experience, manufacturing, marketing, sales, financial and managerial resources than the Company and represent significant competition for the Company. Acquisitions of competing drug delivery companies by large pharmaceutical companies or partnering arrangements between such companies could enhance competitors' financial, marketing and other resources. The Company's competitors may succeed in developing competing technologies, obtaining FDA approval for products more rapidly than the Company and gaining greater market acceptance of their products than the Company's products. There can be no assurance that developments by others will not render some or all of the Company's proposed products or technologies uncompetitive or obsolete, which would have a material adverse effect on the Company. <PAGE 26> Dependence on Key Personnel The Company is dependent upon a limited number of key management and technical personnel. The loss of the services of one or more of such key employees could have a material adverse effect on the Company. In addition, the Company's success will depend upon its ability to attract and retain additional highly qualified sales, management, manufacturing and research and development personnel. The Company faces intense competition in its recruiting activities, and there can be no assurance that the Company will be able to attract or retain qualified personnel. Exposure to Product Liability The research, development and commercialization of medical devices and therapeutic products entails significant product liability risks. If the Company succeeds in commercializing products using the SmartMist system or the AERx system and if it succeeds in developing additional devices and new products, the use of such products in clinical trials and the commercial sale of such products may expose the Company to liability claims. These claims might be made directly by consumers or by pharmaceutical companies or others selling such products. Companies often address the exposure of such risk by obtaining product liability insurance. Although the Company currently maintains limited product liability insurance, there can be no assurance that the Company will be able to obtain additional or maintain existing insurance on acceptable terms, or at all, or in amounts sufficient to protect the Company. A successful claim brought against the Company in excess of the Company's insurance coverage would have a material adverse effect on the Company's business. <PAGE 27> Uncertainty Related to Third-Party Reimbursement In both domestic and foreign markets, sales of the Company's current and potential products, if any, will depend in part on the availability of reimbursement from third-party payors such as government health administration authorities, private health insurers and other organizations. Third-party payors are increasingly challenging the price and cost effectiveness of medical products and services. Significant uncertainty exists as to the reimbursement status of newly approved health care products. There can be no assurance that any of the Company's current and potential products will be reimbursable by thirdparty payors. In addition, there can be no assurance that the Company's current and potential products will be considered cost-effective or that adequate third-party reimbursement will be available to enable Aradigm to maintain price levels sufficient to realize a profit. Legislation and regulations affecting the pricing of pharmaceuticals may change before the Company's current and potential products are approved for marketing and any such changes could further limit reimbursement. <PAGE 28> Hazardous Materials The Company's operations involve the controlled use of hazardous materials, chemicals and various radioactive compounds. Although the Company believes that its safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, the Company could be held liable for any damages that result and such liability could exceed the resources of the Company. Possible Volatility of Stock Price The market prices for securities of many companies, including the Company, engaged in pharmaceutical development activities historically have been highly volatile and the market from time to time has experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Prices for the Company's Common Stock may be influenced by many factors, including investor perception of the Company, fluctuations in the Company's operating results and market conditions relating to the pharmaceutical industry. In addition, announcements of technological innovations or new commercial products by the Company or its competitors, delays in the development or approval of the Company's product candidates, developments or disputes concerning patent or proprietary rights, publicity regarding actual or potential developments relating to products under development by the Company or its competitors, regulatory developments in both the United States and foreign countries, public concern as to the safety of drug technologies and economic and other external factors, as well as period-to-period fluctuations in financial results, may have a significant impact on the market price of the Common Stock. Finally, future sales of substantial amounts of Common Stock by existing shareholders could also adversely affect the prevailing price of the Common Stock. In the past, following periods of volatility in the market price of a company's securities, class action securities litigation has often been instituted against such a company. Any such litigation instigated against the Company could result in substantial costs and a diversion of management's attention and resources, which could have a material adverse effect on the Company's business, financial condition and operating results. <PAGE 29> Item 8.

Organization and Summary of Significant Accounting Policies Organization and Basis of Presentation Aradigm Corporation (the "Company") was incorporated in California. Through June 1997, prior to the signing of the Company's collaborative agreement with SmithKline Beecham (see Note 7), the Company was in the development stage. Since inception, Aradigm has been engaged in the development and commercialization of noninvasive pulmonary drug delivery systems. The Company does not anticipate receiving significant revenue from the sale of products in the upcoming year. Principal activities to date have included obtaining financing, recruiting management and technical personnel, securing operating facilities, conducting research and development, and expanding commercial production capabilities. These factors indicate that the Company's ability to continue its research, development and commercialization activities is dependent upon the ability of management to obtain additional financing as required. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. <PAGE 35> Depreciation and Amortization The Company records property and equipment at cost and calculates depreciation using the straight-line method over the estimated useful lives of the respective assets, generally four to seven years. Machinery and equipment acquired under capital leases is amortized over the useful lives of the assets. Leasehold improvements are amortized over the shorter of the term of the lease or useful life of the improvement. Revenue Recognition Contract revenues consist of revenue from collaboration agreements and feasibility studies. The Company recognizes revenue ratably under the agreements as costs are incurred. Deferred revenue represents the portion of research payments received that has not been earned. In accordance with contract terms, upfront and milestone payments from collaborative research agreements are considered reimbursements for costs incurred under the agreements and, accordingly, are generally deferred when received and recognized as revenue based on actual efforts expended over the remaining terms of the agreements. Nonrefundable signing or license fee payments that are not dependent on future performance under collaborative agreements are recognized as revenue when received. Costs of contract revenue approximate such revenue and are included in research and development expenses. <PAGE 36> Net Loss Per Share Effective December 31, 1997, the Company adopted Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"). SFAS 128 requires the presentation of basic earnings (loss) per share and diluted earnings (loss) per share, if more dilutive, for all periods presented. In accordance with SFAS 128, basic net loss per share has been computed using the weighted average number of shares of common stock outstanding during the period. Net loss per share for 1996 and 1995 have been retroactively restated to apply the requirements of Staff Accounting Bulletin No. 98, issued by the SEC in February 1998 ("SAB 98"). Under SAB 98, certain shares of common stock and options to purchase shares of common stock issued at prices substantially below the per share price of shares sold in the Company's initial public offering previously included in the computation of shares outstanding pursuant to Staff Accounting Bulletin Nos. 55, 64 and 83 are now excluded from the computation. The following pro forma per share data, as adjusted, is provided to show the calculation on a consistent basis for 1997, 1996 and 1995. It has been computed as described above, but includes the retroactive effect from the date of issuance of the conversion of convertible preferred stock to common shares upon the closing of the Company's initial public offering in June 1996. A reconciliation of shares used in the calculation of historical and pro forma, as adjusted, basic and diluted net loss per share follows: <PAGE 37> Year ended December 31, 1997 1996 1995 Net loss $(14,684) $(9,082) $(5,433) Basic and Diluted Weighted average common shares outstanding used in computing basic and diluted net loss 10,280,091 6,098,038 1,004,133 per share Basic and diluted net loss per $ (1.43) $(1.49) $(5.41) share Pro Forma Basic and Diluted, as adjusted Shares used in computing basic and diluted net loss per 10,280,091 6,098,038 1,004,133 share Adjusted to reflect the effect - 2,529,456 3,503,468 of the assumed conversion of preferred stock Shares used in computing pro forma basic and diluted net 10,280,091 8,627,494 4,507,601 loss per share, as adjusted Pro forma basic and diluted net loss per share, as $ (1.43) $(1.05) $(1.21) adjusted Had the Company been in a net income position, diluted earnings per share would have included the shares used in the computation of pro forma basic net loss per share as well as an additional 222,031 shares related to outstanding options and warrants not included above (as determined using the treasury stock method). <PAGE 38> Employee Benefit Plans The Company has a 401(k) Plan which stipulates that all full time employees with at least three months of employment can elect to contribute to the 401(k) Plan, subject to certain limitations, up to 20% of salary on a pretax basis. The Company has the option to provide matching contributions but has not done so to date. Recent Accounting Pronouncements In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive Income," and Statement of Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related Information," which require additional disclosures to be adopted beginning in the first quarter of 1998 and on December 31, 1998, respectively. Under SFAS 130, the Company is required to display comprehensive income and its components as part of the Company's full set of financial statements. SFAS 131 requires that the Company report financial and descriptive information about its reportable operating segments. The Company is evaluating the impact, if any, of SFAS 130 and SFAS 131 on its future financial statement disclosures, but does not believe the additional disclosure will be material to the financial statements. Reclassifications Certain reclassifications of prior year amounts have been made to conform with current year presentation. 2. Financial Instruments Cash Equivalents and Investments The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The Company places its cash and cash equivalents in money market funds, commercial paper and corporate master notes. The Company's shortterm investments consist of corporate notes and market auction preferred securities with maturities ranging from 3 to 12 months. Other investments consist of corporate notes with maturities greater than 12 months. <PAGE 39> The Company classifies its investments as available-for sale. Available-for-sale investments are recorded at fair value with unrealized gains and losses reported in the statement of shareholders' equity. Fair values of investments are based on quoted market prices, where available. Realized gains and losses, which have been immaterial to date, are included in interest and other income and are derived using the specific identification method for determining the cost of investments sold. Dividend and interest income is recognized when earned. The following summarizes the Company's cash equivalents and investments: Estimated Fair Value at December 31, 1997 1996 Cash and cash equivalents: Money market fund $ 6,000 $17,000 Commercial paper 14,331,000 16,939,000 $ 14,337,000 $16,956,000 Short-term investments: Commercial paper $ 3,272,000 $ - Corporate notes 3,216,000 6,978,000 Market auction preferred securities 2,300,000 1,100,000 $ 8,788,000 $8,078,000 Investments: Corporate notes $ - $3,002,000 As of December 31, 1997 and 1996, the difference between the estimated fair value and the amortized cost of available-for sale securities was immaterial. As of December 31, 1997, the average portfolio duration was approximately two months, and the contractual maturity of any single investment did not exceed six months from the balance sheet date. <PAGE 40> 3. Inventories Inventories are stated at the lower of cost (first-in first out basis) or market. Inventories consist of the following: December 31, 1997 1996 Raw materials $479,000 $ - Finished goods 41,000 - $520,000 $ - 4. Property and Equipment Property and equipment consist of the following: December 31, 1997 1996 Machinery and equipment $3,294,000 $601,000 Furniture and fixtures 434,000 273,000 Lab equipment 1,048,000 594,000 Computer equipment and software 755,000 496,000 Leasehold improvements 288,000 201,000 5,819,000 2,164,000 Less accumulated depreciation and (1,402,000) (711,000) amortization $4,417,000 $1,453,000 Property and equipment at December 31, 1997 includes assets under capitalized leases of approximately $3,322,000 ($980,000 in 1996). Accumulated amortization related to leased assets was approximately $392,000 at December 31, 1997 ($344,000 in 1996). <PAGE 41> 5. Leases and Commitments In August 1997, the Company obtained an additional $5.0 million equipment lease line of credit of which approximately $2.9 million remains available at December 31, 1997 for purchases through September 1998. Amounts borrowed under the Company's equipment lines of credit bear interest at rates from 10% to 15% and are collateralized by the equipment purchased. Under the terms of the lease agreements, the Company has the option to purchase the leased equipment at a negotiated price at the end of each lease term. The Company leases its office and laboratory facilities under several operating leases expiring through the year 2014. Future minimum lease payments under noncancelable operating and capital leases at December 31, 1997 are as follows: Operating Capital Leases Leases Years ending December 31: 1998 $843,000 $954,000 1999 1,066,000 842,000 2000 1,298,000 723,000 2001 1,620,000 684,000 2002 and thereafter 33,539,000 462,000 Total minimum lease payments $38,366,000 3,665,000 Less amount representing interest (944,000) Present value of future lease 2,721,000 payments Current portion of capital lease (582,000) obligations Noncurrent portion of capital lease $2,139,000 obligations Rent expense under these operating leases totaled $420,000, $197,000, and $76,000 for the years ended December 31, 1997, 1996, and 1995, respectively. <PAGE 42> 6. Shareholders' Equity Capital Stock In June 1996, the Company completed the initial public offering of its common stock. The Company issued 2,500,000 shares for net proceeds of $24.6 million. Prior to the closing of the initial public offering, the Company effected a three-for-two split of its outstanding common stock. Concurrent with the closing of the initial public offering, previously outstanding shares of Series A, B, C, D and E preferred stock were converted into 5,611,911 shares of common stock. All share and per share data in the accompanying financial statements has been adjusted retroactively to give effect to the stock split. Stock Warrants In September 1997, in connection with a consulting agreement, the Company issued a warrant that entitles the holder to purchase 170,000 shares of common stock at an exercise price of $8.96 per share. This warrant is exercisable through August 2003. In June 1995, in connection with a master lease agreement, the Company issued a warrant that entitles the holder to purchase 37,500 shares of common stock at an exercise price of $4.23 per share. This warrant is exercisable through June 20, 1998. At December 31, 1997, the Company has reserved 207,500 shares of its common stock for issuance upon exercise of these common stock warrants. No amounts have been recorded for the above warrant issuances as the amounts were determined to be immaterial at the time of issuance. <PAGE 43> 1996 Equity Incentive Plan In April 1996, the Company's Board of Directors adopted and the Company's shareholders approved the 1996 Equity Incentive Plan (the "Plan"), which amended and restated the 1992 Stock Option Plan. Options granted under the Plan may be either incentive or nonstatutory stock options. At December 31, 1997, the Company had authorized 1,980,000 shares of common stock for issuance under the Plan. Options granted under the Plan expire no later than ten years from the date of grant. For incentive and nonstatutory stock option grants, the option price shall be at least 100% and 85%, respectively, of the fair value on the date of grant, as determined by the Board of Directors. If at any time the Company grants an option, and the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the option price shall be at least 110% of the fair value and shall not be exercisable more than five years after the date of grant. Options granted under the 1996 Equity Incentive Plan are immediately exercisable and generally vest over a period of four years from the date of grant. Under the Plan, employees may exercise options in exchange for a note payable to the Company. As of December 31, 1997 and 1996, notes receivable from shareholders of $386,000 and $483,000, respectively, were outstanding. These notes generally bear interest at 6% and are due and payable in regular installments over a five year period. Any unvested stock issued is subject to repurchase agreements whereby the Company has the option to repurchase unvested shares upon termination of employment at the original issue price. The common stock has voting rights but does not have resale rights prior to vesting. During 1997, the Company granted options to purchase 550,600 shares of common stock none of which were exercised. The Company has repurchased a total of 24,229 shares in accordance with these agreements. As of December 31, 1997, 219,410 shares of the Company's common stock remained subject to repurchase and 985,099 shares were reserved for issuance upon exercise of options. <PAGE 44> The following is a summary of activity under the Plan: Options Outstanding Shares Available Weighted for Grant Number of Price Per Average of Shares Share Exercise Options Price Balance at 270,825 539,175 $0.10- $0.29 December 31, 1994 $0.37 Shares 150,000 - $ - $ - authorized Shares granted (290,550) 290,550 $0.33- $0.43 $0.43 Shares - (335,876) $0.33- $0.38 exercised $0.43 Shares 41,607 (41,607) $0.33- $0.39 cancelled $0.43 Balance at 171,882 452,242 $0.10- $0.30 December 31, 1995 $0.43 Shares 1,005,000 - $- $- authorized Shares granted (523,520) 523,520 $0.57- $3.66 $9.88 Shares - (662,629) $0.10- $0.53 exercised $5.33 Balance at 653,362 313,133 $0.10- $5.45 December 31, 1996 $9.88 Shares granted (550,600) 550,600 $6.88- $8.75 $12.88 Shares - (5,625) $5.33 $5.33 exercised Shares 24,229 - $0.37- $0.49 repurchased $0.57 Shares 26,825 (26,825) $5.33- $6.03 cancelled $9.88 Balance at 153,816 831,283 $0.10- $7.62 December 31, 1997 $12.88 Options Outstanding and Exercisable Weighted Weighted Average Average Remaining Exercise Price Range Number Exercise Contractual Price Life (in years) $0.10-$2.00 69,033 $0.46 6.6 $4.00-$6.88 188,900 $5.70 8.7 $7.00-$9.88 473,200 $8.42 9.2 $11.13-$12.88 100,150 $12.35 9.8 $0.10-$12.88 831,283 $7.62 9.0 The Company has elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), and the related Interpretations in accounting for its employee and non-employee director stock options because, as discussed below, the alternative fair value accounting provided for under Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), requires use of option pricing valuation models that were not developed for use in valuing employee stock options. Under APB 25, the Company has generally recognized no compensation expense with respect to such awards. <PAGE 45> The Company recorded deferred compensation of approximately $495,000 for the difference between the grant price and the deemed fair value of certain of the Company's common stock options granted in 1996. This amount is being amortized over the vesting period of the individual options, generally a 48 month period. Deferred compensation expense recognized in the years ended December 31, 1997 and 1996 was approximately $204,000 and $187,000, respectively. The weighted average fair value of options granted during 1996 with an exercise price below the deemed fair value of the Company's common stock on the date of grant was $2.15. There were no such grants in 1997. The weighted average fair value of options granted during 1997 and 1996 with an exercise price equal to the fair value of the Company's common stock on the date of grant was $3.35 and $5.60, respectively. Pro forma information regarding net loss and basic and diluted net loss per share is required by SFAS 123, which also requires that the information be determined as if the Company had accounted for its employee and non- employee director stock options granted subsequent to December 31, 1994 under the fair value method prescribed by this statement. The fair value of options was estimated at the date of grant using the Black-Scholes option pricing model with the following assumptions: a risk-free interest rate ranging from 5.7%-6.4%, 5.1%-5.8% and 5.5%-7.9% for the years ending December 31, 1997, 1996 and 1995, respectively; a dividend yield of 0.0%; a volatility factor of the expected market price of the Company's common stock of 0.7; and a weighted average expected option life of four years. Options granted prior to the Company's initial public offering in June 1996 have a volatility factor of 0.0. <PAGE 46> For purposes of pro forma disclosure, the estimated fair value of the options is amortized to expense over the vesting period of the options using the straight-line method. Pro forma information on the above basis is as follows: Year ended December 31, 1997 1996 1995 Pro forma net loss $(14,960,000) $(9,117,000) $(5,437,000) Net loss - as reported $(14,684,000) $(9,082,000) $(5,433,000) Pro forma basic and $ (1.46) $ (1.50) $(5.41) diluted net loss per share Basic and diluted net $ (1.43) $ (1.49) $(5.41) loss per share - as reported The effects of applying SFAS 123 for pro forma disclosures are not likely to be representative of the effects on reported net loss for future years. Pro forma net loss for the year ended December 31, 1997 reflects compensation expense for three years' vesting, while the year ending December 31, 1998 will reflect compensation expense for four years' vesting of outstanding stock options. Employee Stock Purchase Plan Under the Employee Stock Purchase Plan (the "Purchase Plan"), 150,000 shares of common stock have been authorized for issuance. Shares may be purchased under the Purchase Plan at 85% of the lesser of the fair market value of the common stock on the grant date or purchase date. As of December 31, 1997, 21,824 shares have been issued under the Purchase Plan. 1996 Non-Employee Directors' Stock Option Plan The 1996 Non-Employee Directors' Stock Option Plan (the "Directors' Plan") authorizes the grant of 225,000 options for the Company's common stock. As of December 31, 1997, 52,500 options have been granted under the Directors' Plan. <PAGE 47> 7. Collaborative Agreements In September 1997, the Company executed a development and commercialization agreement with SmithKline Beecham covering use of the AERx Pain Management System for the delivery of narcotic analgesics. The Company and SmithKline Beecham will collaborate on the development of the products within this field. Under the terms of the agreement, SmithKline Beecham has been granted exclusive worldwide sales and marketing rights to the AERx Pain Management System for use with such analgesics, and Aradigm retains all manufacturing rights. If this system receives regulatory approval, Aradigm expects to sell devices and drug packets to SmithKline Beecham and to receive royalties on sales by SmithKline Beecham. Pursuant to the SmithKline Beecham agreement, Aradigm could receive up to approximately $30 million in milestone and product development payments, and $10 million in equity investments if and when the first product from the collaboration is commercialized. In October 1997, the Company received $14 million from SmithKline Beecham under the agreement, of which $5 million resulted from the sale of shares of Aradigm Common Stock. Additional milestone and product development payments will be paid if Aradigm and SmithKline Beecham decide to jointly develop additional AERx products which incorporate other opiates or opioids. Through December 31, 1997, the Company has recognized total contract revenue of $2.7 million. <PAGE 48> In December 1996, the Company entered into a feasibility agreement with a pharmaceutical company to determine the feasibility of using the Company's AERx(TM) Pulmonary Drug Delivery System for the delivery of a specified drug. The agreement provides for a $169,500 research and development payment and a $237,500 payment upon acceptance by the pharmaceutical company of certain specified deliverables. All revenue under this agreement was recognized in 1997. In December 1995, the Company entered into a feasibility agreement with a pharmaceutical company to determine the feasibility of using the Company's AERx Pulmonary Drug Delivery System for the delivery of a specified drug. The agreement provided for a $260,000 research and development payment. Under this agreement, revenues of $30,000 and $230,000 were recognized in 1995 and 1996, respectively. In November 1996, the Company entered into a second such agreement with the pharmaceutical company that provided for a $140,000 research and development payment. Costs associated with research and development activities attributable to these agreements are expected to approximate the revenues recognized. The agreement also provided for a nonrefundable license fee of $500,000 upon execution of the agreement, which was recognized as revenue in 1996. 8. Related Party Transactions <PAGE 49> At December 31, 1997, the Company has notes receivable, including accrued interest, totaling $303,000 from officers of the Company. Included therein are $153,000 of promissory notes bearing interest at 6%-7% per annum, generally due and payable three years from the date of the notes, and collateralized by certain personal assets of the officers and a $90,000 full recourse promissory note bearing no interest and due and payable in September 1998. At December 31, 1997, the fair value of these notes is not materially different from their carrying values. The fair values were estimated using discounted cash flow analyses, using interest rates currently offered for loans with similar terms and to borrowers of similar credit quality. 9. Income Taxes The Company uses the liability method to account for income taxes as required by Statement of Financial Accounting Standards No. 109, "Accounting for Income taxes". Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using enacted tax rules and laws that are expected to be in effect when the differences are expected to reverse. Significant components of the Company's deferred tax assets are as follows: December 31, 1997 1996 Net operating loss carryforward $13,735,000 $7,336,000 Research and development credit 1,769,000 851,000 carryforward Other 36,000 611,000 Gross deferred tax assets 15,540,000 8,798,000 Valuation allowance (15,540,000) (8,798,000) Net deferred tax assets $ - $ - The valuation allowance increased by $6,742,000 and $3,751,000 in 1997 and 1996, respectively. <PAGE 50> At December 31, 1997, the Company had net operating loss carryforwards of approximately $35,000,000 for federal income tax purposes expiring in the years 2006 through 2012 and net operating losses for state income tax purposes of $33,000,000 expiring in the years 1998 through 2002. At December 31, 1997, the Company had research and development credit carryforwards for federal income tax purposes of approximately $1,380,000, which expire in the years 2006 through 2012. Because of the "change in ownership" provisions of the Tax Reform Act of 1986, utilization of the Company's tax net operating loss carryforwards and tax credit carryforwards may be subject to an annual limitation in future periods. As a result of the annual limitation, a portion of these carryforwards may expire before ultimately becoming available to reduce future income tax liabilities. <PAGE 51> PART IV Item 14.
