Overview

    Matrix® Pharmaceutical, Inc. ("Matrix" or "the Company") is a development-stage company that is developing novel drug product candidates for cancer based on its internal research and development capabilities and through in-licensing of product candidates from other pharmaceutical companies.

    The Company is a leader in the formulation and development of novel pharmaceutical product candidates that are designed to improve the delivery of cancer drugs for more effective treatment of solid tumors. The Company has applied its expertise in tumor biology and physiology, advanced imaging techniques, pharmaceutical chemistry, polymer chemistry, analytical chemistry and biochemistry, and chemical engineering to develop proprietary systems that facilitate the direct delivery and retention of anticancer agents in solid tumors. The Company has developed aqueous-based protein gel systems for delivery of water-soluble chemotherapeutic agents and non-aqueous semi-solid systems for delivery of chemotherapeutic agents that are poorly water soluble. Two product candidates that utilize the Company's aqueous-based protein gel systems are currently being evaluated in human clinical trials. These are IntraDose® (cisplatin/epinephrine) Injectable Gel and MPI 5020 Radiopotentiator. IntraDose incorporates cisplatin, an established chemotherapeutic agent. MPI 5020 incorporates fluorouracil, another established chemotherapeutic agent.

    In addition to developing product candidates based on its technology, the Company also licenses product candidates for development, utilizing its expertise to identify and subsequently implement appropriate development strategies for in-licensed compounds. In-licensed in 1998, Matrix is developing FMdC as an intravenously-administered therapeutic in non-small cell lung cancer, colorectal cancer, hematologic and other cancers.

Matrix Technology

    Aqueous-based protein systems.  IntraDose and MPI 5020 Radiopotentiator are based on the Company's patented injectable gel technology, in which a chemotherapeutic drug is combined with a protein matrix and, in IntraDose, a vasoconstrictor, to create an injectable gel. This gel enables targeted delivery of anticancer drugs by direct injection into solid tumors. The Matrix delivery system localizes the release of drug, maintaining high drug concentrations at the tumor or lesion site and increasing the duration of exposure of the targeted tissue to the therapeutic agent. The activity of Intradose is further enhanced by the addition of epinephrine, a vasoconstrictor which reduces local blood flow and acts as a "chemical tourniquet" to further hold the drug at the site of the disease.

    The Company believes that its technology may allow the development of new products from established drugs or newer agents which may be available from other companies or institutions. Whether or not the chosen drugs or compounds are "off-patent," when they are incorporated into the Company's proprietary drug delivery system, the resulting products are proprietary to the Company. The Company, therefore, expects to be competitive in the marketplace and have a proprietary position in such products for the length of the patents on its technology and resulting products.

    Cisplatin and fluorouracil are widely used as systemic agents to treat solid tumors. These chemotherapeutic drugs exert a cytotoxic effect on dividing cells at various stages during their growth and multiplication. Cells that undergo rapid and unregulated cell division are more susceptible than normal cells to the effects of such drugs. Unfortunately, normal cells (e.g., bone marrow and gastrointestinal mucosa cells) rapidly divide and are also sensitive to the cytotoxic drugs. This toxicity to normal tissue limits the maximum dosing permitted with systemically administered chemotherapeutic drugs and often results in a tolerated dose that is substantially lower than the dose necessary to kill all diseased tissue. Suboptimal dosing contributes to the emergence of drug resistance among remaining cancer cells, complicating further drug therapy.

    The Company believes that the principal advantages of its aqueous-based protein systems technology include:


    Anhydrous Delivery Vehicles ("ADV").  Approximately half of the anti-cancer drugs in use today, including paclitaxel, etoposide, and teniposide, are poorly soluble in water, posing difficulties for administration by conventional systemic routes such as intravenous ("IV") injection or infusion. The solubilizing agents employed in several of these drug products to prepare suitable IV solutions may add to toxicity. The Company has developed a series of non-aqueous delivery vehicles (anhydrous delivery vehicles, or ADVs) which in preclinical experiments significantly enhance the local efficacy of these drugs compared to the efficacy obtained when these drugs are delivered systemically using more conventional aqueous delivery systems. The Company believes that ADV carriers may be applicable to a large variety of water-insoluble drugs, with the potential to significantly improve the clinical utility of these agents. The Company believes that this technology may also lend itself well to water-soluble drugs that have limited stability when dissolved in aqueous media. Until such time as a corporate partner is identified and additional financial resources are provided, the Company does not intend to initiate clinical development of any product candidate based on the ADV technology.

IntraDose Injectable Gel

    Matrix is developing IntraDose Injectable Gel for head and neck cancer and a variety of other solid tumors. Ninety percent of cancer patients suffer from solid tumors (i.e., carcinomas and sarcomas). Approximately 70% of these patients have local disease with no evidence of metastatic disease at the time of diagnosis. Conventional therapies for cancer include surgery, radiation and systemic drug therapy. Despite continued advances in these treatments, they are limited by negative side effects, such as loss of normal body functions, weakness, loss of appetite and nausea, which are the result of the killing, altering or removing of normal cell tissue. Therefore, quality of life factors such as pain management and control of other tumor related symptoms become important, as do the potential to retard disease progression and possibly prolong survival.

    The Company's IntraDose product candidate represents a new approach to the treatment of solid tumors. IntraDose is designed for direct injection into solid tumors, including primary, metastatic and recurrent tumors. Imaging techniques such as endoscopy, ultrasound, computerized tomography ("CT" scan) and magnetic resonance imaging ("MRI" scan) have substantially increased the number of solid tumors potentially treatable by the Company's products. The Company believes IntraDose may be efficacious when used as a single agent as well as when used in combination with conventional treatment modalities. In addition, the Company believes that treatments with IntraDose may be given in any out-patient setting that is equipped to administer cytotoxic drugs, offering the potential for cost-effective treatment without in-patient hospitalization for surgery or prolonged chemotherapy.

Head and Neck Cancer/Other Solid Tumors

    The Company is currently completing two randomized placebo-controlled Phase III clinical trials for head and neck cancer. Enrollment for these two studies was completed in January 2000 with patient treatment and follow-up expected to be completed during the first half of 2000. Two open-label Phase III trials in other solid tumors including recurrent chest wall metastases (from breast cancer, ovarian cancer and lung cancer), esophageal cancer, melanoma, and various other carcinomas were completed in 1999. These tumors may be either primary, recurrent, or metastatic. The Company believes that these cancers are well suited to a direct injection with the Company's IntraDose product as they are either visible, palpable or easily accessible with an endoscope. The Company plans to utilize data from its trials in head and neck cancer and other solid tumors to support its request for approval of the broadest possible label for IntraDose in the United States and Western Europe.

    Head and Neck Cancer Market.  The prevalence of head and neck cancer in the United States is estimated at 134,000 patients. In addition, the Company estimates that approximately 41,000 new cases of head and neck cancer are diagnosed annually in the United States and 73,000 new cases are diagnosed annually in Western Europe, based on data from the American Cancer Society and The International Agency for Research on Cancer, a unit of the World Health Organization. The incidence (number of new cases per year) is highest in patients with high rates of cigarette smoking and consumption of alcoholic beverages. Cancers of the head and neck are predominately squamous cell carcinomas. Of these, approximately 60% to 70% are diagnosed as later stage disease which has spread beyond the site of origin, and 30% to 40% are diagnosed as early stage disease that is localized. Cancers of the head and neck are often difficult to treat with conventional surgery and radiotherapy techniques. Tumor location can make surgical resection difficult or impossible due to proximity to vital body structures and/or cosmetic or functional considerations, while radiotherapy often damages surrounding healthy tissues. The use of systemic chemotherapy in the management of head and neck cancers has been limited by the difficulty of achieving adequate and lasting tumor responses without incurring unacceptable side effects. This has led to a continuing investigation of new chemotherapeutics and combinations of chemotherapy, radiation, and surgery. The most important limitation of the available therapies for head and neck cancer is the high recurrence rate, generally 50% or higher.

    A standard course of chemotherapy for patients with head and neck cancer often requires hospitalization with daily intravenous infusion of chemotherapy. The majority of patients who receive chemotherapy will also require ancillary supportive treatments, such as intravenous fluids, nutritional support, antiemetics or growth factor support to control the toxic side effects of the chemotherapy. Clinical results suggest that the use of IntraDose may not require some or any of these supportive treatments.

    Other Solid Tumor Market.  Tumors that can be accessed and injected directly or by means of an endoscopic procedure or minimally invasive technique include chest wall metastases from primary breast cancer, tumors of the esophagus, and malignant melanomas of the skin. The Company believes that approximately 76,000 cases are diagnosed each year in the United States (comprised of approximately 25,000 cases of chest wall metastases from primary breast cancer, 10,000 cases of esophageal cancer, and 41,000 cases of malignant melanoma) and that approximately 71,000 cases are diagnosed each year in

4


Western Europe (approximately 26,000 in chest wall metastases from primary breast cancer, 24,000 in esophageal cancer, and 21,000 in malignant melanoma), based on data from the American Cancer Society and The International Agency for Research on Cancer. Recurrent solid tumors of these types were evaluated in the Company's open-label Phase III trials. Metastatic tumors found in the chest wall and other locations are usually treated with systemic chemotherapy and radiotherapy. However, this approach often leads to the development of drug resistance or cumulative radiation toxicity. Currently there are few treatment options for recurrent tumors.

    Clinical Studies.  In 1992, an open-label Phase I/II clinical trial for the treatment of head and neck cancer and other solid tumors was initiated. This clinical trial was conducted in 45 patients with a total of 82 treated tumors. The study was published in Otolaryngology-Head and Neck Surgery, the journal of the American Academy of Otolaryngology-Head and Neck Surgery Foundation. Forty-one of the 45 patients had received radiotherapy or cancer drug therapy prior to being treated with IntraDose, factors which reduce the likelihood of a significant response to the future use of chemotherapy. In this trial, 39% (32 of 82) of all treated tumors exhibited a complete response (100% reduction in tumor volume) and 50% of all treated tumors (41 of 82) exhibited a complete response or partial response (greater than 50% reduction in tumor volume). A response was defined as tumor reduction of any duration, rather than duration lasting at least 28 days, the standard clinical definition of a response, because some patients received systemic chemotherapy for treatment of disease progression in distant, untreated tumors shortly after being treated successfully with IntraDose. Sixteen of the complete responses (19.5% of treated tumors) without other therapy could be followed for at least 28 days without other therapy and had a lasting complete response. The median duration of complete response was 125 days.

    IntraDose achieved these response rates in these patients with advanced disease without causing a clinically unacceptable level of systemic toxicity. Dose-limiting toxicity was not observed in this trial, and the overall side effects were deemed to be moderate in severity when compared to standard chemotherapy regimens. The most commonly observed side effects were irritation, inflammation and damage to the tissues in and around the injected tumor. However, these patients did not experience any of the principal side effects associated with the systemic use of cisplatin, including nephrotoxicity and ototoxicity.

    In June 1995, the Company announced initiation of two Phase III trials for patients with head and neck cancer and two trials for patients with other solid tumors. The randomized double-blind, placebo-controlled Phase III head and neck cancer trials were designed to enroll approximately 180 evaluable patients, 90 patients in the United States trial and 90 patients in the European trial. The two Phase III studies for other solid tumors were open-label studies designed to include approximately 130 evaluable patients, 65 in the United States and 65 in Western Europe. Patients enrolled in these Phase III trials had advanced recurrent or refractory disease. The study endpoints are objective tumor responses (i.e., durable tumor shrinkage at or greater than 28 days of at least 50%) and achievement of pre-selected treatment goals, such as prevention of obstruction of vital structures, pain control, wound care, improvement in ability to hear, see, and eat, prevention of breakthrough of the skin and other paliative benefits.

    In September 1998, the Company announced that the other solid tumor studies were fully enrolled with 127 patients. In November 1998, preliminary clinical results were presented on a subset of patients at the 16th annual Chemotherapy Foundation Symposium. In May 1999, updated study results were presented at the American Society of Clinical Oncology ("ASCO"). Data were presented at ASCO on 102 evaluable patients including 28 women with advanced breast cancer, 25 patients with malignant melanoma, 18 patients with esophageal cancer and 31 patients with a variety of recurrent and metastatic primary tumors. For most patients, two or more tumors were treated, including one that was identified by the physician before the start of treatment as most troublesome, that is, the tumor that was most threatening or bothersome to the patient. Patients achieved objective tumor response rates of 50% in the most troublesome breast tumors, 48% in the most troublesome malignant melanomas and 39% in the most troublesome esophageal cancer. Among the breast tumors, six of the 14 responses were complete (100% reduction of tumor volume for at least 28 days) and eight were partial (50% or greater reduction of tumor

5


volume for at least 28 days). Among the melanomas, six of the 12 responses were complete and six were partial. Eight of the 12 melanoma responses were sustained until the patients went off study. The other four patients received additional therapies during study follow-up for distant melanomas not treated with IntraDose. Among the esophageal patients, seven patients out of 18 had partial responses. In patients with recurrent breast cancer, 46% (13/28) achieved a patient benefit as assessed by the investigator and/or the patient against predetermined treatment goals. Of the patients with malignant melanoma, 36% (9/25) achieved a patient benefit. Of the patients with esophageal cancer, 44% (8/18) achieved a patient benefit. The therapy was generally well tolerated with 23% or fewer of the patients experiencing the nausea and vomiting symptoms typically related to intravenous chemotherapy. The most commonly reported side effects were local tissue reactions including but not limited to necrosis, erythema (redness) and swelling at the treatment site and injection-related pain. There was a positive and statistically significant association between "Most Troublesome Tumor ("MTT") response and achievement of patient benefit: patients with MTT responses were twice as likely to attain benefit as those with less than a 50% MTT response (i.e. "nonresponder").

    In January 2000, the Company announced that the head and neck cancer studies were fully enrolled with a total of 179 patients, 88 in North America and 91 outside North America. The Company had previously disclosed that, in consultation with the FDA, study entry criteria had been revised to exclude patients with neck tumors close to the carotid artery, who are susceptible to cerebral vascular events including strokes and other serious neurological adverse events. If results from these two studies are adequate, the Company anticipates using the data from these trials to support regulatory submissions in the United States in the fourth quarter of 2000 and Western Europe in early 2001.

Liver Cancer

    Two types of cancers are commonly found in the liver—primary hepatocellular cancer (cancer arising from liver cells) and tumors originating in other tissues (most commonly from colorectal cancer) that have metastasized to the liver. Primary liver cancer is a significant health problem worldwide and especially in the parts of the world where hepatitis B is prevalent (e.g., Japan, Korea and Southeast Asia). It is estimated that there will be 540,000 new cases in 2000 worldwide. The Company believes the incidence of primary hepatocellular cancer is approximately 14,500 in the United States and 17,500 in Western Europe and the incidence of hepatic metastases from colorectal cancers is approximately 36,000 and 73,000 in the United States and Western Europe, respectively, based on data available from the American Cancer Society and The International Agency for Research on Cancer. However, some experts predict that the incidence of primary hepatocellular cancer may increase due to the frequency of hepatitis B and C carriers. There are currently no FDA approved drug or pharmaceutical therapies for the treatment of primary hepatocellular cancer. The Company believes that this is an area where there is significant unmet medical need.

    When possible, surgery is most often the first line treatment for both types of liver tumors. However, a majority of patients with liver tumors are inoperable due to tumor location, tumor size, and extent of disease. For unresectable liver cancer, treatments have included the use of systemic chemotherapy, radiotherapy, cryotherapy, hepatic arterial infusion of chemotherapy and chemoembolization (blocking or draining a blood vessel while injecting chemotherapy), all of which are applicable to a minority of patients and have had limited beneficial results. Due to the limited availability and effectiveness of current therapies, the Company believes that at most approximately 50% of all patients with liver cancer are treated. The Company believes that IntraDose may offer enhanced tumor reduction as well as outpatient flexibility with the potential for improved quality of life as compared to non-surgical alternatives.

    In 1992, clinical investigators began treating patients with both forms of unresectable liver cancer in a Phase I/II clinical trial program. The investigators treated 28 patients who had 25 tumors evaluable for tumor necrosis (tumor destruction, estimated by CT scan). Ten of the 25 evaluable tumors exhibited at least 90% necrosis in response to IntraDose treatment. Patients were treated in an outpatient setting, with the treatment guided by either CT or ultrasound.

6



    Patients treated in this study did not experience the typical side effects associated with intravenous cisplatin, such as nephrotoxicity, neurologic changes or ototoxicity. In addition, in a pharmacokinetics study conducted in patients treated at the M.D. Anderson Cancer Center, less than 10% of the platinum levels anticipated from a standard intravenous dose of cisplatin were found in patient plasma after treatment with IntraDose. The majority of the IntraDose product was confined to the treated tumor.

    In 1997, the Company initiated two open-label Phase II trials for patients with liver cancer. A Phase II trial for patients with primary hepatocellular cancer was initiated at medical centers in the United States, Europe, and Hong Kong. A Phase II trial for patients with cancers metastatic to the liver from colorectal cancer was initiated at medical centers in the United States and Europe. These trials are designed to evaluate tumor necrosis and tumor response (as measured by CT scan), time to tumor progression, pattern of disease progression, and patient survival.

    In April, 1999, the Company expanded enrollment in the Phase ll primary hepatocellular cancer study from 37 patients up to a maximum of 55 patients.

    In August 1999, the company concluded enrollment in the Phase ll trial for patients with colorectal cancer metastatic to the liver. Thirty-one patients have been entered on study with follow-up and analysis to be completed and announced at an appropriate medical conference in 2000.

    In November 1999, the Company announced that 12 of 29 (41%) evaluable patients with primary hepatocellular cancer responded to treatment with IntraDose. Of the initial 12 responders, six experienced complete response (100% reduction in viable tumor volume) while the other six responders showed a reduction in viable tumor of at least 50%. As of this report, the median survival was in excess of 15 months. Two patients of the 12 subsequently progressed, after 197 and 156 days of response respectively. In both patients, progression was due to development of new tumors distant from the treated tumors and not due to growth of the treated tumors.

    Tumor response in this trial has been determined utilizing investigator site imaging techniques to estimate and assess the amount of necrotic tissue versus viable tumor in identified tumors. No independent review of the imaging response has been used in determining tumor response and the Company expects that an independent review could lead to differing measurements of tumor response.

FMdC

    FMdC, licensed from Hoechst Marion Roussel, Inc. in September 1998, is a new chemical entity that belongs to a class of anticancer and antiviral agents known as nucleoside analogs. Several nucleoside analogs are marketed for treatment of certain leukemias or lymphomas, malignancies of white blood cells. In addition, another nucleoside analog is marketed for treatment of pancreatic cancer and non-small cell lung cancer, both of which are solid tumor malignancies. Preclinical testing indicates that FMdC may have activity against solid tumors and may also be active against cancers of hematopoietic or blood cell origin.

    FMdC is an analog of deoxycytidine, one of the four nucleotides, or bases, that form DNA. Researchers believe FMdC has several modes of action. The two most important of these are thought to be DNA chain termination during DNA replication and repair and inhibition of ribonucleotide reductase, an enzyme that manufactures nucleotides (nucleic acid bases) for incorporation into DNA. FMdC can be incorporated directly into the replicating strand of DNA. Once FMdC is incorporated, the enzymes responsible for further synthesis cannot add additional nucleotides to the DNA chain. This causes the DNA chain to terminate before it is completely copied and leads to the death of the cell. The incorporation of FMdC into DNA is also facilitated by FMdC's inhibition of ribonucleotide reductase, as this inhibition reduces the supply of the nucleic acid bases that are necessary for DNA replication. Additionally, experiments indicate that FMdC suppresses production of a protein that stimulates the growth of blood vessels near tumors, suggesting that FMdC also may have anti-angiogenic properties.

7



    Animal studies by Hoechst Marion Roussel and now by the Company indicate that FMdC is effective against a broad spectrum of human and rodent tumors, including tumors of the lung, colon, breast (estrogen-dependent and estrogen-independent), prostate, ovaries, and pancreas. It has been shown in laboratory studies to be a more effective DNA chain terminator and inhibitor of ribonucleotide reductase than certain other nucleoside analogs with known cytotoxic activity.

    In an intravenous dosage form, FMdC was generally well tolerated in four Phase I studies conducted by Hoechst Marion Roussel, Inc. Side effects included fever, flushing, and clinically manageable reductions in white blood cell counts. FMdC has a relatively long plasma half life of three to six hours, which also may make it more effective than other nucleoside analogs. A Phase I trial of an oral dosage form of FMdC has been completed in Japan by Kyowa Hakko, Ltd.. The Company believes that an oral formulation may eventually be of benefit in terms of outpatient and administrative flexibility.

Lung Cancer

    The American Cancer Society estimates that non-small cell lung cancer is the leading cause of cancer deaths in the United States, accounting for 75% of the 160,100 lung cancer deaths expected this year as well as 75% of the 171,500 expected new cases of lung cancer. Lung cancer is also one of the most common forms of cancer and one of the most frequent causes of death from cancer in the European Union. The International Agency for Research on Cancer estimates that 182,398 new cases of lung cancer are diagnosed each year in the European Union and 173,042 deaths occur each year from lung cancer.

    First line treatment of non-small cell lung cancer is often initially treated with surgery or radiation treatments. Many patients are not eligible for curative surgery. Relapse rates are high, due it is believed, to the presence of metastatic disease. For relapsing patients, treatment options are single-agent chemotherapy, combination-agent chemotherapy, or best supportive care. The advent of newer chemotherapeutic agents has improved patient response, but durable complete responses for more than one year are infrequently achieved. Effective new agents with novel mechanisms of anticancer activity and favorable toxicity profiles are needed to improve the outcome for these patients.

    In February 1999, a Phase II study of FMdC in patients with non-small cell lung cancer was initiated in the United States. In October 1999, the Company closed enrollment in this Phase ll study as the result of the application of a predetermined stopping rule. Preliminary analysis of the evaluable patients did not show meaningful clinical activity with FMdC as a stand-alone therapy in this indication at the dose and regimen tested. The Company also plans to evaluate alternative dose levels and regimens.

Colon and Rectal Cancer

    The prevalence of colorectal cancer is estimated to be over 540,000 patients in the United States and 575,000 in the European Union. Growth in the incidence of colorectal cancer is increasing in both the United States and Europe. The American Cancer Society estimates that there will be 129,000 new cases of colorectal cancer in the United States. According to the International Agency for Research on Cancer almost 200,000 new cases are expected in the European Union. Surgery is the primary treatment for colon and rectal cancer. Unfortunately approximately 55% of patients will either not be amenable to surgical cure or have recurrent cancer subsequent to surgery.

    Chemotherapy is used for paliation for patients who are not cured by surgery. Chemotherapy with an intravenous fluorouracil-based treatment is considered to be standard. Fluorouracil has been shown to be more cytotoxic, with increased response rates but with variable effects on survival, when given in combination with leucovorin or methotrexate. Continuous-infusion fluorouracil regimens have also resulted in increased response rates in some studies, with a modest benefit in median survival. Fluorouracil is in the class of drugs called fluoropyrimidines. Several oral fluoropyrimidines are being evaluated in phase II-III trials. Recently the NDA was filed for one oral fluoropyrimidine, capecitabine, for advanced colorectal cancer. Approximately 15-20% of patients have a palliative partial response to

8


fluoropyrimidines. Irinotecan (CPT-11) is a topoisomerase-I inhibitor with a 10% to 20% partial response rate in patients who have received no prior chemotherapy, and in patients progressing on 5-FU. CPT-11 is now considered standard palliative therapy for patients who do not respond to or progress on 5-FU.

    In May 1999, a Phase ll study of FMdC in patients with colon cancer was initiated in the United States. This study is currently in progress and is expected to be completed during the first half of 2000.

Combination Therapies

    Preclinical studies performed by the Company indicated synergistic activity of FMdC and certain other agents. The Company commenced additional focused phase Ia/Ib studies of FMdC for lung cancer during 2000 in combination with cisplatin, which could potentiate the response to FMdC.

    In February 2000, the Company commenced development of combination therapies with a phase I study to evaluate FMdC in combination with fluorouracil. Depending upon the results of this trial, the Company may consider additional trials to evaluate FMdC in combination therapy with fluorouracil for other cancers including colon cancer.

Hematologic Cancer

    Matrix is also collaborating with M.D. Anderson Cancer Center, where phase I/II investigator sponsored studies are being conducted in a variety of hematologic cancers and lymphoma. These studies commenced in November 1999.

MPI 5020 Radiopotentiator

    Radiation therapy remains a critical tool in the management of many types of solid tumors. However, radiation resistance, hypoxic tumor cells, and normal tissue sensitivity to radiation has limited the benefit of this therapy. Using its platform technologies, the Company has demonstrated in preclinical experiments that intratumoral delivery of radiopotentiating agents significantly enhances the effects of radiation in solid tumors. The Company's lead candidate in this area, MPI 5020, is a fluorouracil based product that uses the Company's aqueous protein gel technology.

    In 1997, the Company initiated a Phase I trial in chest wall metastatic disease from recurrent breast cancer at medical centers in the United States. This dose-escalation study is intended to evaluate the safety of MPI 5020 when administered in conjunction with standard radiotherapy and to compare the effect on tumor regression of tumors treated with MPI 5020 and radiotherapy to tumors treated with radiotherapy alone.

    Preliminary information from this ongoing trial was reported at the annual meeting of the American Society for Therapeutic Radiation and Oncology in October 1998 and at the Annual San Antonio (Texas) Breast Cancer Symposium in December 1998. Patients have been treated in five dose-escalation and frequency-schedule treatment regimens, and the combined use of radiation therapy and MPI 5020 has been found to be feasible and well tolerated.

    The Company has concluded the dose escalation phase of development and is currently gathering and analyzing clinical data. No further clinical work is expected on MPI 5020 during 2000. Further clinical development of the MPI 5020 program will depend on a number of factors including the ability of the Company to secure adequate funding from other pharmaceutical companies.

Preclinical Programs

    The Company has focused certain preclinical research efforts on delivery of topoisomerase inhibitors and tubulin-binding agents through Matrix's proprietary ADV technology. Topoisomerase inhibitors and tubulin-binding agents are classes of chemical compounds that have demonstrated potent anti-cancer

9


activity in vitro and in vivo but are poorly water soluble. In order to be administered intravenously, many of these chemical compounds have been formulated with solubilizing agents that may cause serious systemic side effects. The Company believes its ADV technology may improve the therapeutic ratio (i.e., to increase a drug's local effectiveness and/or significantly reduce dose-limiting side effects which result from its systemic administration) of these and other poorly water soluble anti-cancer agents.

    Further clinical development of the ADV technology will depend on the ability of the Company to secure funding from other pharmaceutical companies.

AccuSite™ Injectable Gel

    The Company has withdrawn its new drug application for AccuSite™ Injectable Gel in the United States as it was deemed non-approvable by the FDA. In 1999, the Company withdrew all license applications to market AccuSite™ Injectable Gel in Europe.

Manufacturing and Supply

    Matrix maintains worldwide manufacturing rights to all of its products. The Company has manufactured collagen for IntraDose and MPI 5020 at facilities it operated in San Jose and Milpitas, California, and obtained other product components from contract manufacturing facilities. The Company's San Jose and Milpitas facilities were closed during 1998 as part of a restructuring of the Company's work force and consolidation of manufacturing operations in a 67,000 square foot research and manufacturing facility in San Diego, California, which the Company acquired in 1995. In March 1998, the Company entered into a sale and leaseback agreement for the San Diego facility. See Item 2, "Properties." Following extensive renovations, the San Diego facility became operational in 1998 for the non-sterile purification of collagen and aseptic processing and sterile filling of collagen gels as well as for all materials-receiving activities, labeling, packaging and shipping operations. The Company intends to use the San Diego facility to meet its near-term clinical trials and long-term commercial scale production requirements for collagen for its IntraDose products. The Company will also utilize the San Diego facility for contract manufacturing for other pharmaceutical and medical device companies in order to generate revenues and offset operating costs. The facility has passed inspection by the State of California but will require approval by the U.S. Food and Drug Administration prior to commercialization of products manufactured there. The Company has acquired supplies of FMdC sufficient for anticipated near-term pre-clinical and clinical needs. For longer-term production of FMdC, the Company plans to contract for chemical production needs and do a combination of internal and contract manufacturing for pharmaceutical production needs.

    The Company's ability to conduct clinical trials on a timely basis, to obtain regulatory approvals and to commercialize its products will depend in part upon its ability to manufacture its products, either directly or through third parties, at a competitive cost and in accordance with applicable FDA and other regulatory requirements, including cGMP regulations. Several of the materials used in the Company's products are available from a limited number of suppliers. These items, including collagen gel and various bulk drug substances, have generally been available to Matrix on commercially reasonable terms. If the Company's manufacturing facilities are not able to produce sufficient quantities of collagen gel in accordance with applicable regulations, the Company would have to obtain collagen gel from another source and gain regulatory approval for that source. Matrix has negotiated and intends to continue to negotiate supply agreements, as appropriate, for the raw materials and components utilized in its products.

Sales and Marketing

    The Company currently owns worldwide marketing rights for all its products under development, except for FMdC in Japan. The Company's business strategy is to market or co-market IntraDose and its other oncology product candidates, if approved, in the United States and to license its products outside the

10


United States to pharmaceutical partners who have substantially greater resources and experience in local markets. See "Risk Factors—We Have Limited Manufacturing and Sales and Marketing Experience."

Patents and Proprietary Rights

    The Company's policy is to aggressively seek patent protection and to enforce all of its intellectual property rights. In the United States, the Company has eleven issued patents, one allowed patent and four pending applications. In Western Europe, the Company has three issued patents and seven pending applications. The Company has four issued patents and several pending applications in Japan. Ten of the eleven patents issued in the United States relate to the Company's base technologies. The first of these three patents claims compositions consisting of collagen or fibrinogen as protein matrices, cytotoxic and antiproliferative drugs, and (optionally) a vasoconstrictive agent. This patent also covers the method of use of these compositions in treating cancerous or hyperproliferative lesions by local application; it expires in the United States in 2003 and in Europe in 2005. A second patent, which expires in the United States in 2007, includes pharmaceutical compositions consisting of a range of cytotoxic agents (including radionuclides, etc.) in combination with vasoconstrictive agents and (optionally) a variety of other tissue modifiers, formulated in aqueous pharmacologically acceptable vehicles. The method of use of these compositions in treating cancerous lesions by local application is also covered. A third patent covers certain formulations of the ADV technology for delivering water-insoluble anti-cancer drugs, and specifically covers water-immiscible fatty acid ester matrices containing cytostatic agents and their use for treating cancer via intralesional administration. Another patent application covering Intradose composition of matter claims has been allowed in the United States and is in prosecution in Europe. This patent will expire in 2015 in the United States and Europe. Two additional patents in the United States, which expire in 2015, cover certain drug-containing collagen gels, including MPI 5020, AccuSite and, potentially, other products developed by the Company. The other issued patents cover a key aspect of the Company's collagen manufacturing process, as well as other ancillary drug products.

    As part of the in-licensing agreement of FMdC, the Company has received licenses to a patent portfolio on this technology in the United States, Europe and many other countries with the exception of Japan. The first of these patent families is a composition-of-matter and method-of-use case covering FMdC (and related compounds) and their use in treating neoplastic or viral disease. The European patents in this family expire in 2009, and the last of the U.S. patents in this family expires in 2014. A second patent family covers the synthetic method by which FMdC is made; the last of these patents expire in 2013 in the United States and Europe. Another U.S. patent covers the use of combinations of FMdC and radiation (U.S. expiry 2014, ex-U.S. in prosecution) and several other synthetic process and method-of-use patents (combination chemotherapy with other cytotoxic drugs, combination antiviral therapy, etc.) are issued in Europe or in prosecution in the United States and Europe.

Competition

    The development of therapeutic agents for human disease is intensely competitive. Many different approaches are being developed or have already been adopted for routine use for the management of diseases targeted by the Company. Certain cancers and skin diseases are targets for therapeutic product development at numerous entities, many of which have greater human and financial resources than the Company. In addition, conventional drug therapy, surgery and other more established treatments and modalities will compete with the Company's products.

    The pharmaceutical industry is subject to rapid and substantial technological change. Technological competition from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase. Most of these entities have significantly greater research and development capabilities, as well as substantial marketing, financial and managerial resources, and represent significant competition for the Company. Acquisitions of, or investments in, competing biotechnology companies by large pharmaceutical companies could increase such

11


competitors' financial, marketing and other resources. There can be no assurance that developments by others will not render the Company's products or technologies noncompetitive, or that the Company will be able to keep pace with technological developments. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Some of these products may have an entirely different approach or means of accomplishing the therapeutic effect than products being developed by the Company. These competing products may be more effective and less costly than the products developed by the Company.

    The Company's competitive position depends upon, among other factors, its ability to attract and retain qualified personnel, obtain patent protection or otherwise develop proprietary products or processes and secure sufficient capital resources to complete product development and regulatory processes. The Company expects that competition among products approved for sale will be based, among other factors, on product activity, safety, reliability, availability, price, patent position and new usage and purchasing patterns established by managed care and other group purchasing organizations.

Government Regulation

    The Company and its products are subject to comprehensive regulation by the FDA in the United States and by comparable authorities in other countries. These national agencies and other federal, state, and local entities regulate, among other things, the preclinical and clinical testing, safety, effectiveness, approval, manufacture, labeling, marketing, export, storage, record keeping, advertising, and promotion of the Company's products.

    The process required by the FDA before the Company's products may be approved for marketing in the United States generally involves (i) preclinical laboratory and animal tests; (ii) submission to the FDA of an IND, which must become effective before clinical trials may begin; (iii) adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug for its intended indication; (iv) submission to the FDA of an NDA, and; (v) FDA review of the NDA in order to determine, among other things, whether the drug is safe and effective for its intended uses. When a product contains more than one active drug component, as do some of the Company's current product candidates, the FDA may request that additional data be submitted in order to demonstrate the contribution of each such component to clinical efficacy.

    Clinical trials are typically conducted in three sequential phases which may overlap. During Phase I, when the drug is initially given to human subjects, the product is tested for safety, dosage tolerance, absorption, metabolism, distribution, and excretion. Phase II involves studies in a limited patient population to (i) evaluate preliminarily the efficacy of the product for specific, targeted indications, (ii) determine dosage tolerance and optimal dosage, and (iii) identify possible adverse effects and safety risks. Phase III trials are undertaken in order to further evaluate clinical efficacy and safety within an expanded patient population at geographically dispersed clinical study sites. The FDA may suspend clinical trials at any point in this process if it concludes that clinical subjects are being exposed to an unacceptable health risk.

    FDA approval of the Company's products, including a review of the manufacturing processes and facilities used to produce such products, is required before such products may be marketed in the United States. The process of obtaining approvals from the FDA can be costly, time consuming, and subject to unanticipated delays. Any failure or delay in obtaining such approvals would adversely affect the ability of the Company to market its proposed products. Moreover, even if regulatory approval is granted, such approval may include significant limitations on indicated uses for which a product could be marketed.

    The processes required by European regulatory authorities before the Company's products can be marketed in Western Europe are similar to those in the United States. First, appropriate preclinical laboratory and animal tests as well as analytical product quality tests must be done, followed by submission of a CTX or similar documentation before human clinical trials can be initiated. Upon completion of

12


adequate and well controlled clinical trials in humans that establish the drug is safe and efficacious, regulatory approval must be obtained from the relevant regulatory authorities.

    The proposed products and technologies of the Company may also be subject to certain other federal, state, and local government laws and regulations, including, but not limited to, various environmental laws, the Occupational Safety and Health Act, and state, local, and foreign counterparts to such laws. Compliance with such laws and regulations does not have, nor is such compliance presently expected to have, a material adverse effect on the business of the Company.

Research and Development

    The Company's sponsored research and development expenses were approximately $27,214,000, $20,186,000 and $17,743,000 in 1997, 1998, and 1999, respectively.

Employees

    As of December 31, 1999, the Company had a total of 93 full-time employees, including 21 in research and development, 26 in medical and regulatory affairs, biostatistics, and technical services, 26 in manufacturing, and 20 in other departments. The Company believes that it has been successful in attracting and retaining skilled and experienced personnel; however, competition for such personnel is intense and there can be no assurance that the Company will be successful at attracting and retaining qualified personnel in the future. None of the Company's employees are covered by collective bargaining agreements and management considers relations with its employees to be good.

RISK FACTORS

We May Not Receive Regulatory Approvals of our Product Candidates, Manufacturing Processes and Production Facilities

    The preclinical and clinical testing, manufacturing, and marketing of our products are subject to extensive regulation by numerous governmental authorities in the United States and other countries, including the Food and Drug Administration, or FDA. Among other requirements, the FDA must approve our product candidates, manufacturing processes and production facilities before we may market them in the United States. Similarly, a foreign governmental authority must typically approve the marketing of a product before that product's manufacturer can market it in a particular foreign country. We have no products approved by the FDA and we do not expect to achieve profitable operations unless our product candidates now under development receive FDA and foreign regulatory approval and are thereafter commercialized successfully. Subsequent to the approval of AccuSite by foreign authorities in certain countries in Europe all marketing applications have been withdrawn. We have had only limited experience in submitting and pursuing regulatory applications. The process of obtaining FDA approvals can be costly, time consuming and subject to unanticipated delays, and we can give no assurance that the FDA will grant us any approvals on a timely basis, or at all.

    The process of obtaining FDA regulatory approval involves a number of steps that, taken together, may involve seven years or more from the initiation of clinical trials and require the expenditure of substantial resources. Among other requirements, this process requires that the product candidate undergo extensive preclinical and clinical testing to demonstrate its safety and efficacy for its intended uses. We must also file a New Drug Application, or NDA, requesting FDA approval. When a product contains more than one component that contributes to the product's effect, as do some of our current product candidates, the FDA may request that additional data be submitted in order to demonstrate the contribution of each such component to clinical efficacy.

    In addition, prior to approval of a product, the FDA must inspect and accept the product's manufacturing facilities as being in compliance with its Good Manufacturing Practices, or GMP, regulations. We can give no assurance that the FDA will accept our San Diego manufacturing facility, and failure to receive or maintain such acceptance would materially and adversely affect our business.

    When we submit an NDA, the FDA must review and interpret our analysis of the results of our clinical studies submitted as part of the NDA. Any FDA interpretation may differ from our analysis, and we can give no assurance that the FDA will accept our data or our interpretation of that data. NDAs for drug candidates that the FDA determines address life-threatening diseases may be given more rapid ("fast track") regulatory review, which is generally six months from submission. IntraDose Injectable Gel was granted "fast track" status in May 1999. Although this designation is expected to shorten the review period compared to NDAs that do not have "fast track" status, it does not increase or decrease the probability of FDA approval. In addition, changes in applicable law or FDA policy during the period of product development and FDA regulatory review may result in the delay or rejection of our NDA. Any failure to obtain, or delay in obtaining, FDA approvals would adversely affect our ability to market our proposed products. Moreover, even if FDA approval is granted, the approval may include significant limitations on indicated uses for which a product could be marketed.

    Violations of regulatory requirements at any stage, including the preclinical and clinical testing process, the approval process or after approval, may result in adverse consequences, including the FDA's delay in approving or refusal to approve a product, withdrawal of an approved product from the market, and/or the imposition of criminal penalties against the manufacturer and/or the NDA holder. In addition, the subsequent discovery of previously unknown problems relating to a marketed product may result in restrictions on such product, manufacturer, or the NDA holder, including withdrawal of the product from the market. Also, new government requirements may be established that could delay or prevent regulatory approval of our products under development.

14



    The processes required by European regulatory authorities before our product candidates can be marketed in Western Europe are similar to those in the United States. We must first complete appropriate preclinical laboratory and animal tests as well as analytical product quality tests and then submit a clinical trial exemption or similar documentation before we can initiate human clinical trials. Upon completion of adequate and well-controlled clinical trials in humans that establish that the drug is safe and efficacious, we must obtain regulatory approval from the relevant regulatory authorities.

Uncertainties Associated with Clinical Trials

    We have conducted and plan to continue to undertake extensive and costly clinical testing to assess the safety and efficacy of our potential products. Failure to comply with FDA regulations applicable to clinical testing can result in delay, suspension, or cancellation of this testing, or refusal by the FDA to accept the results of this testing. In addition, we or the FDA may modify or suspend clinical trials at any time if the FDA concludes that the subjects or patients participating in the trials are being exposed to unacceptable health risks. Further, we can give no assurance that human clinical testing will show any current or future product candidate to be safe and effective or provide data suitable for submission to the FDA.

    We are currently conducting multiple clinical trials in the United States and certain foreign countries, including two ongoing Phase III trials. The rate of completion of our clinical trials depends upon, among other factors, the rate of patient enrollment. Patient enrollment is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites and the eligibility criteria for the study. We experienced slower than planned accrual of patients in our ongoing Phase III trials. Delays in completing enrollment in other clinical studies may result in increased costs and delays, which could materially and adversely affect our business. Generally, similar considerations apply to clinical testing that is subject to regulatory oversight by foreign authorities and/or that is intended to be used in connection with foreign marketing applications.

    Additionally, we extended enrollment in a Phase II Intradose trial beyond the original number of patients planned for that study. Although this action was taken due to the encouraging results observed to date, final study results may be different from the preliminary outcomes as more patients are entered onto the study and as patients are followed for a longer period of time.

We Have a History of Losses and Our Future Profitability is Uncertain

    We incorporated in 1985 and have experienced significant losses since that date. As of December 31, 1999, our accumulated deficit was approximately $187,967,000. We have not generated revenues from our products or product candidates and expect to incur significant additional losses over the next several years. In order to achieve a profitable level of operations, we must successfully develop products, obtain regulatory approvals for our products, enter into agreements for product commercialization outside the United States, and develop an effective sales and marketing organization in the United States. We can give no assurance that we will complete our product development efforts, that we will obtain the required regulatory approvals, that we will manufacture or market any products successfully, or that we will achieve profitability.

We Will Require Additional Financing

    We have expended and will continue to expend substantial funds to complete the research and development of our product candidates. We may require additional funds for these purposes through additional equity or debt financings, collaborative arrangements with corporate partners or from other sources. We can give no assurance that such additional funds will be available on acceptable terms, if at all. Our business could be materially and adversely affected if adequate funds are not available from operations or additional sources of financing. Based on our current operating plan, we anticipate that our

15


existing capital resources will be adequate to satisfy our capital needs through at least mid-2001. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

We Have Limited Manufacturing and Sales and Marketing Experience

    We intend to market and sell certain of our product candidates, if successfully developed and approved, through our own dedicated sales force in the United States and through pharmaceutical licensees in Europe. We can give no assurance that we will be able to establish a successful direct sales organization or co-promotion or distribution arrangements. In addition, we can give no assurance that resources will be available to us to fund our marketing and sales expenses, many of which must be incurred before sales commence. Failure to establish a marketing and sales capability in the United States or outside the United States may materially and adversely affect our business.

    Our ability to conduct clinical trials on a timely basis, to obtain regulatory approvals and to commercialize our products will depend in part upon our ability to manufacture our products, either directly or through third parties, at a competitive cost and in accordance with applicable FDA and other regulatory requirements, including GMP regulations. We closed our manufacturing facilities in San Jose and Milpitas, California in March 1998 and transferred manufacturing personnel to a research and manufacturing facility in San Diego, California that we acquired in 1995 to meet our anticipated long-term commercial scale production requirements. We expect that the San Diego facility and contract manufacturers should provide sufficient production capacity to meet clinical requirements. We can give no assurance that we will be able to validate this facility in a timely manner or that this facility will be adequate for our long-term needs without delaying our ability to meet product demand or to manufacture in a cost-effective manner. We expect to continue to use selected contract manufacturers, in addition to our own manufacturing capability, for some or all of our product components. Failure to establish additional manufacturing capacity on a timely basis materially and adversely affect our business.

We Depend on Our Sources of Supply

    Several of the materials used in our product candidates are available from a limited number of suppliers. These items, including collagen gel and various bulk drug substances, have generally been available to us and others in the pharmaceutical industry on commercially reasonable terms. If our manufacturing facilities are not able to produce sufficient quantities of collagen gel in accordance with applicable regulations, we would have to obtain collagen gel from another source and gain regulatory approval for that source. We can give no assurance that we would be able to locate an alternative, cost-effective source of supply of collagen gel.

    We have negotiated and intend to continue to negotiate supply agreements, as appropriate, for the raw materials and components utilized in our products. Any interruption of supply could materially and adversely affect our ability to manufacture our products, complete clinical trials, or commercialize our products. In addition, the issuance in 1996 of a U.S. patent for cisplatin, a chemotherapeutic drug that is the active compound in our IntraDose Injectable Gel product, could limit our ability to commercialize this product in the United States if the newly-issued patent were upheld, if IntraDose were found to infringe that patent, and if we were unable to obtain a license under that patent. See "Uncertainty Regarding Patents and Proprietary Rights."

Uncertainty Regarding Patents and Proprietary Rights

    Our success depends in part on our ability to obtain patent protection for our products and to preserve our trade secrets and operate without infringing on the proprietary rights of third parties. We have not conducted an exhaustive patent search and we can give no assurance that patents do not exist or could not be filed which would materially and adversely affect our ability to market our products or maintain our competitive position with respect to our products. Our patents may not prevent others from

16


developing competitive products using related technology. Other companies that obtain patents claiming products or processes useful to us may bring infringement actions against us. As a result we may be required to obtain licenses from others to develop, manufacture or market our products. We can give no assurance that we will be able to obtain any such licenses on commercially reasonable terms, if at all. We also rely on trade secrets and proprietary know-how that we seek to protect, in part, by confidentiality agreements with our employees, consultants, suppliers and licensees. We can give no assurance that these third parties will not breach these agreements, that we would have adequate remedies for any breach, or that our trade secrets will not otherwise become known or be independently developed by competitors.

    We can give no assurance that the U.S. Patent and Trademark Office, or PTO, will approve our pending patent applications, and or that any patent issued to, or licensed by us will provide protection that has commercial significance. In this regard, the patent position of pharmaceutical compounds and compositions is particularly uncertain. Even issued patents may later be modified or revoked by the PTO in proceedings instituted by us or others. In addition, we can give no assurance that our patents will afford protection against competitors with similar compounds or technologies, that others will not obtain patents with claims similar to those covered by our patents or applications, or that others' patents will not adversely affect our ability to conduct our business.

    In 1996, for instance, the PTO granted a composition-of-matter patent for the cytotoxic drug cisplatin in the United States licensed to a pharmaceutical company whose use patent on cisplatin as an anti-tumor agent expired in December 1996. We believe on advice of patent counsel that our IntraDose product candidate, which contains cisplatin, does not infringe this new patent. Moreover, the key claims of this new patent were found invalid by the 7th U.S. District Court in October 1999. However, if the court's decision is appealed and overturned, and if IntraDose were found to infringe that upheld patent, there can be no assurance that we would be able to obtain a license to the patent on commercially reasonable terms, if at all, in order to commercialize IntraDose in the United States.

    We believe that obtaining foreign patents may be more difficult than obtaining domestic patents because of differences in patent laws, and recognize that our patent position therefore may be stronger in the United States than abroad. In addition, the protection provided by foreign patents, once they are obtained, may be weaker than that provided by domestic patents.

Risks Related to Rapid Technological Change and Substantial Competition

    The pharmaceutical industry is subject to rapid and substantial technological change. Technological competition in the industry from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase. Most of these entities have significantly greater research and development capabilities, as well as substantially more marketing, financial and managerial resources than us, and represent significant competition for us. Acquisitions of, or investments in, competing biotechnology companies by large pharmaceutical companies could increase these competitors' financial, marketing and other resources. We can give no assurance that developments by others will not render our products or technologies noncompetitive or that we will be able to keep pace with technological developments. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Some of these products may have an entirely different approach or means of accomplishing similar therapeutic endpoints than products that we are developing. These competing products may be more effective and less costly than the products that we are developing. In addition, conventional drug therapy, surgery and other more familiar treatments and modalities will compete with our products.

    Any product that we successfully develop and for which we gain regulatory approval must then compete for market acceptance and market share. Accordingly, important competitive factors, in addition to completion of clinical testing and the receipt of regulatory approval, will include product efficacy, safety,

17


timing and scope of regulatory approvals, availability of supply, marketing and sales capability, reimbursement coverage, pricing and patent protection.

Pharmaceutical Pricing and Adequate Reimbursement is Uncertain

    The continuing efforts of governmental and third party payers to contain or reduce the costs of health care through various means may affect the future revenues, profitability, and availability of capital for biopharmaceutical companies. For example, in certain foreign markets pricing or profitability of prescription pharmaceuticals is subject to government control. In the United States, there have been, and we expect that there will continue to be, a number of federal and state proposals to implement similar government control. Specific legislation is currently being reviewed concerning the reimbursement of oncology drugs. While we cannot predict whether any such legislative or regulatory proposals will be adopted, the announcement or adoption of such proposals could materially and adversely affect our prospects.

    Our ability to commercialize our products successfully will depend in part on the extent to which appropriate oncology-related reimbursement levels for the cost of such products and related treatment are obtained from government authorities, private health insurers and other organizations, such as health maintenance organizations, or HMOs. Third-party payers are increasingly challenging the prices charged for medical products and services. Also, the trend towards managed health care in the United States and the concurrent growth of organizations like HMOs, which could control or significantly influence the purchase of health care services and products, as well as legislative proposals to reform health care or reduce government insurance programs, may limit prices we can charge for our products. The cost containment measures that health care payers and providers are instituting and the effect of any health care reform could adversely affect our ability to sell our products and may materially and adversely affect our business.

We Depend on Qualified and Key Personnel

    Because of the specialized nature of our business, our ability to maintain our competitive position depends on our ability to attract and retain qualified management and scientific personnel. Competition for such personnel is intense. We can give no assurance that we will be able to continue to attract or retain such persons.

Risks Associated with Product Liability Exposure; Limited Insurance Coverage

    We face an inherent business risk of exposure to product liability claims in the event that the use of products during research or commercialization results in adverse effects. While we will continue to take appropriate precautions, we can give no assurance that we will avoid significant product liability exposure. Although we maintain product liability insurance for clinical studies and contract service activities, we can give no assurance that this coverage will be adequate or that adequate insurance coverage for future clinical or commercial activities will be available at all, or at an acceptable cost, or that a product liability claim would not materially adversely affect our business or financial condition.

Risks Associated with Hazardous Materials and Products

    Our research and development involves the controlled use of hazardous materials, such as cytotoxic drugs, other toxic and carcinogenic chemicals and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by federal, state and local regulations, we cannot completely eliminate the risk of accidental contamination or injury from these materials. In the event of this type of accident, we could be held liable for any resulting damages, and any such liability could be extensive. We are also subject to substantial regulation relating to occupational health and safety, environmental protection, hazardous substance

18


control, and waste management and disposal. The failure to comply with such regulations could subject us to, among other things, fines and criminal liability.

    Certain chemotherapeutic agents that we employ in our aqueous-based protein systems, Anhydrous Delivery Vehicles, and regional delivery technology are known to have toxic side effects, particularly when used in traditional methods of administration. Each product incorporating a chemotherapeutic agent will require separate FDA approval as a new drug under the procedures specified above. Bovine collagen is a significant component of our protein matrix. Two rare autoimmune connective tissue conditions, polymyositis and dermatomyositis, have been alleged to occur with increased frequency in patients who have received cosmetic collagen treatments. Based upon the occurrence of these conditions, the FDA requested a major manufacturer of bovine collagen products for cosmetic applications to investigate the safety of such uses of its collagen. In October 1991, an expert panel convened by the FDA to examine this issue found no statistically significant relationships between injectable collagen and the occurrence of autoimmune disease, but noted that certain limitations in the available data made it difficult to establish a statistically significant association.

    In addition, bovine sourced materials are of some concern because of transmission of Bovine Spongiform Encephalopathy, or BSE. We have taken all precautions to minimize the risk of contamination of our collagen with BSE, including the use of United States-sourced hides. The Committee For Proprietary Medicinal Products, a steering committee of the European Medicines Evaluation Agency, has determined that materials made from bovine skin are unlikely to result in any risk of contamination, indicating minimal risk of transmission of BSE.

Our Stock Price is Volatile and We Have Not Declared Any Dividends

    The market prices for securities of biopharmaceutical and biotechnology companies (including us) have historically been highly volatile, and, in addition, the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Future announcements concerning us, our competitors or other biopharmaceutical products, governmental regulation, developments in patent or other proprietary rights, litigation or public concern as to the safety of products that we or others have developed and general market conditions may have a significant effect on the market price of our securities. We have not paid any cash dividends on our Common Stock and do not anticipate paying any dividends in the foreseeable future.

Risks Associated with Anti-Takeover Provisions

    Certain provisions of our Certificate of Incorporation and Bylaws may make it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, control of us. These provisions could limit the price that certain investors might be willing to pay in the future for shares of our Common Stock. Our Board of Directors has the authority to issue shares of Preferred Stock and to determine the price, rights, preferences, privileges and restrictions of those shares without any further vote or action by the stockholders.

    The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any Preferred Stock that may be issued in the future. The issuance of Preferred Stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock. We have no present plans to issue shares of Preferred Stock. Certain provisions of Delaware law applicable to us could also delay or make more difficult a merger, tender offer or proxy contest involving us, including Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless certain conditions are met.

Impact of Year 2000

    In prior years, the Company discussed the nature and progress of its plans to become Year 2000 ready. In late 1999, the Company completed its remediation and testing of systems. As a result of those planning and implementation efforts, the Company experienced no significant disruptions in mission critical information technology and non-information technology systems and believes those systems successfully responded to the Year 2000 date change. The Company spent approximately $100,000 during 1999 in connection with remediating its systems. The Company is not aware of any material problems resulting from Year 2000 issues, either with its products, its internal systems, or the products and services of third parties. The Company will continue to monitor its mission critical computer applications and those of its suppliers and vendors throughout the year 2000 to ensure that any latent Year 2000 matters that may arise are addressed promptly. Although we have converted our internal systems, we cannot fully predict to what extent our business would be affected if any of our suppliers' systems and services are not Year 2000 compliant.

Item 2. Properties

    In March 1998, the Company entered into an agreement with a real estate investment trust for the sale and leaseback of its San Diego manufacturing facility structured as an $18,425,000 purchase and a $6,000,000 convertible loan secured by specific manufacturing related building improvements. The lease has a term of 13 years with options to renew for up to 25 years. Net cash from the lease and loan agreement, after the payment of the existing mortgage and escrow and other related fees, totaled approximately $13,798,000 and is being used to fund operating expenses and capital purchases.

    In 1996, the Company entered into an agreement to lease out a portion of its San Diego manufacturing facility. The original lease which had a term of two years ending July 1998 was extended through July 1999 resulting in rental income of $4,472,000 during the three-year period. In September, 1999 the Company entered into another three-year lease which will result in $2,429,000 in rental income.

    During September 1997, the Company's management suspended further development and commercialization of AccuSite after being notified that the FDA did not approve AccuSite as a treatment for genital warts. Pursuant to the restructuring plan which was established in the third quarter of 1997, the Operations group relocated to the San Diego facility from its Northern California facilities during the fourth quarter of 1997. During the first quarter of 1998, the Company terminated its lease obligation on the manufacturing facility in San Jose and negotiated termination agreements for the manufacturing and storage facilities located in Milpitas, California. Costs associated with the termination of the leases and write-off of leasehold improvements for the leased facilities have been accrued in current liabilities on the balance sheet. See "Management Discussion and Analysis—Results of Operations."

    In May 1994, the Company entered into an 18-year lease agreement beginning in January 1996, for a facility totaling approximately 50,000 square feet in Fremont, California.

    The following discussion should be read in conjunction with the consolidated financial statements and related notes included on pages 36-53.

Overview

    Since the Company's inception in 1985, the primary focus of its operations has been research and development and, to date, it has not received any revenues from the commercial sale of products. The Company has a history of operating losses and expects to incur substantial additional losses over the next several years as it continues to develop its current and future products. For the period from its inception (February 11, 1985) to December 31, 1999, the Company has incurred a cumulative net loss of $187,967,000.

Results of Operations

Years ended December 31, 1999 and 1998.

    The Company had no revenues for 1999 or 1998.

    Research and development expenses for 1999 decreased by 12% to $17,743,000 as compared to $20,186,000 for 1998. The decrease was due to reduced clinical trial program costs including the other solid tumor program which was completed during the fourth quarter of 1998, lower per patient costs for the Company's Intradose programs, lower depreciation, personnel costs and certain manufacturing costs at the San Diego facility. This was partially offset by higher rental expense at the San Diego facility and by the higher costs associated with the FMdC clinical trial program. The increase in the San Diego rent expense is due to lower rental income from the sublease of a portion of the facility.

    For the year ended December 31, 1999, there was no license fee expense as compared to the $4,000,000 license fee in 1998, which was an initial payment to in-license a systemic anticancer agent known as FMdC that is in the early stages of clinical development.

    General and administrative expenses for 1999 decreased by 13% to $5,762,000 compared to $6,649,000 for 1998. The decrease was due to lower personnel costs, consulting, legal and relocation expenses.

    Interest income for 1999 decreased by 31% to $3,091,000 as compared to $4,491,000 as a result of lower average cash balances during the year.

    Other income decreased to $969,000 for 1999 as compared to $6,791,000 for 1998 due primarily to the receipt of $4,000,000 from a settlement with an insurance company and $2,108,000 from the gain on sale and leaseback of the San Diego facility, both of which occurred in 1998.

    Interest expense decreased by 14% to $1,553,000 for 1999 as compared to $1,796,000 for 1998 due to the payoff of certain equipment leases and declining interest payments on equipment loans.

    As of December 31, 1999, the Company had federal and state net operating loss carryforwards of approximately $182,500,000 and $40,000,000, respectively. The Company also had federal research and development tax credit carryforwards of approximately $3,900,000. The federal net operating loss and credit carryforwards will expire at various dates beginning in the year 2000 through 2019, if not utilized. The state of California net operating losses will expire at various dates beginning in 2000 through 2004, if not utilized.

Years ended December 31, 1998 and 1997.

    The Company had no revenues for 1998 or 1997.

    Research and development expenses for 1998 decreased by 26% to $20,186,000 as compared to $27,214,000 for 1997. The decrease was primarily due to lower personnel costs, the suspension of clinical

25


trials for AccuSite™ Injectable Gel and lower consulting expenses. The decrease was partially offset by higher depreciation expense and building rent expense in 1998 in connection with the sale and leaseback transaction for the San Diego manufacturing facility.

    An in-license fee of $4,000,000 was recorded during the third quarter of fiscal 1998 in connection with a new agreement to in-license a systemic anticancer agent known as FMdC which is in the early stages of clinical development. There were no license fees in the year ended 1997.

    General and administrative expenses for 1998 decreased by 53% to $6,649,000 compared to $14,270,000 for 1997. The decrease was due primarily to lower litigation-related expenses, the absence of AccuSite-related product marketing expenses and lower personnel costs.

    For 1998, no special charges were recorded as compared to special charges of $4,518,000 which were recorded during the third quarter of fiscal 1997 in connection with the decision to suspend further development and commercialization of AccuSite. Management suspended the AccuSite program after the FDA notified the Company that it was not prepared to approve AccuSite as a treatment for genital warts. In September 1997, costs to conclude the clinical trials and commercial programs associated with AccuSite were accrued. The Company reduced its workforce by 63 employees, of which 46 positions related to manufacturing, resulting in severance expenses of $1,478,000. Additional expenses included the write-off of inventory related to AccuSite of $1,245,000, costs totaling $1,194,000 associated with the shut down of the Company's Northern California facilities and write-off of manufacturing equipment, the closing of clinical trials with respect to AccuSite of $414,000, and committed sales and marketing costs associated with AccuSite of $187,000. At December 31, 1998, the remaining reserve balance of $513,000 was included in current liabilities and is primarily for future cash payments related to facility lease costs.

    Interest income decreased by 20% to $4,491,000 as compared to $5,561,000 as a result of lower average cash balances during the year.

    Other income increased to $6,791,000 for 1998 as compared to $1,819,000 for 1997 due primarily to the receipt of $4,000,000 from a settlement with an insurance company, $2,108,000 from the gain on sale and leaseback of the San Diego facility and $560,000 from amortization of a five year non-compete agreement.

    Interest expense increased by 62% to $1,796,000 for 1998 as compared to $1,109,000 for 1997 due to the impact of new building and equipment financing loans of $10,000,000 in the fourth quarter of 1997 and $6,000,000 in 1998 offset by the payoff of the San Diego mortgage loan in the amount of $9,840,000 in 1998.

Liquidity and Capital Resources

    At December 31, 1999, the Company had $46,971,000 in cash, cash equivalents and marketable securities, compared to $66,545,000 at December 31, 1998. The decrease of $19,574,000 in cash, cash equivalents and short-term investments during the year ended December 31, 1999 reflects $19,271,000 of cash disbursements used to fund operating activities, payments of $1,755,000 on debt and capital lease obligations and capital purchases of $428,000. This was partially offset by cash received for the purchase of the Company's common stock in the amount of $1,743,000.

    In September 1998, the Company entered into an agreement to license a systemic anticancer agent known as FMdC for $4,000,000. The in-license fee was recorded in the third quarter of 1998.

    In April 1998, the Company received $4,000,000 from an insurance company for the reimbursement of legal expenses incurred during prior years. The payment settles litigation between the Company and the insurer over coverage under the Company's general liability policy. The payment was recorded as other income in the second quarter of 1998.

26


    In March 1998, the Company entered into an agreement with a real estate investment trust for the sale and leaseback of its San Diego manufacturing facility structured as an $18,425,000 purchase and a $6,000,000 convertible loan secured by specific manufacturing related building improvements. The lease has a term of 13 years with the option to renew up to 25 years. Net cash from the lease and loan agreement, after the payment of the existing mortgage and escrow and other related fees, totaled approximately $13,798,000 and is being used to fund operating expenses and capital purchases.

    In October 1997, the Company received $10,000,000 before commitment fees, as part of a five-year equipment financing agreement maturing in 2002. The agreement is secured by equipment purchased by the Company between October 21, 1995 and March 31, 1998.

    Special charges of approximately $4,518,000 were recorded during the third quarter of 1997 in connection with the decision to suspend further development and commercialization of AccuSite. See "Results of Operations". Total cash payments in 1999 for restructuring were approximately $513,000 with no amount payable at December 31, 1999.

    In September 1995, the Company repurchased from Medeva PLC all marketing rights related to its AccuSite product for $2,000,000, to be paid over a period of five years. As of December 31, 1999, the remaining balance of this obligation was $500,000.

    The Company has financed its operations and capital asset acquisitions from its inception through the sale of equity securities, interest income, and capital lease and debt financing. The Company expects to finance its continued operating requirements principally with cash on hand and marketable securities as well as additional capital that may be generated through equity and debt financings and collaborative agreements.

    The Company's working capital and capital requirements will depend on numerous factors, including the progress of the Company's research and development programs, preclinical testing and clinical trial activities, the timing and cost of obtaining regulatory approvals, the levels of resources that the Company devotes to the development of manufacturing and marketing capabilities, technological advances and the status of competitors.

    The Company expects to incur substantial additional costs relating to the continued clinical development of its oncology products, continued research and development programs, the development of manufacturing capabilities, and general working capital requirements. The Company anticipates that its existing and committed capital resources will enable it to maintain its current and planned operations at least through mid-2001. The Company may require additional outside financing to complete the process of bringing current products to market, and there can be no assurance that such financing will be available on favorable terms, if at all.

    Capital expenditures for environmental control efforts were not material during the 1999 and 1998 fiscal years.

Year 2000

    In prior years, the Company discussed the nature and progress of its plans to become Year 2000 ready. In late 1999, the Company completed its remediation and testing of systems. As a result of those planning and implementation efforts, the Company experienced no significant disruptions in mission critical information technology and non-information technology systems and believes those systems successfully responded to the Year 2000 date change. The Company spent approximately $100,000 during 1999 in connection with remediating its systems. The Company is not aware of any material problems resulting from Year 2000 issues, either with its products, its internal systems, or the products and services of third parties. The Company will continue to monitor its mission critical computer applications and those of its suppliers and vendors throughout the year 2000 to ensure that any latent Year 2000 matters that may arise are addressed promptly.

MATRIX PHARMACEUTICAL, INC.
(a development stage company)

Notes to Consolidated Financial Statements

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Basis of presentation.  Matrix Pharmaceutical, Inc. (the "Company") was incorporated in California on February 11, 1985 and reincorporated in Delaware in January 1992. The Company's principal activities to date have involved research and development of drug delivery systems using proprietary technology, in-licensing of a product candidate, recruiting key personnel, establishing a manufacturing process and raising capital to finance its development operations. The Company is classified as a development stage company.

    In the course of its development activities, the Company has sustained continuing operating losses and expects such losses to continue over the next several years. The Company has financed its operations and capital acquisitions primarily through stock issuances, capital leases, and subsequent to 1996, by long-term debt.

    Certain amounts have been reclassified to conform with current period classification.

    Principles of consolidation.  The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary after elimination of all material intercompany balances and transactions.

    Cash and cash equivalents and short-term investments.  The Company invests its excess cash in government and corporate debt securities. Highly liquid investments with maturities of three months or less at the date of acquisition are considered by the Company to be cash equivalents. All other investments are reported as short-term investments.

    Marketable securities available-for-sale.  All marketable securities are classified as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses reported as a separate component of stockholders' equity. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretions of discounts to maturity. Such amortization is included in interest income. Realized gains and losses and declines in value judged to be other than temporary for available-for-sale securities are included in interest and other expense. The cost of securities sold is based on the specific identification method.

    Depreciation and amortization.  The Company depreciates property and equipment using the straight-line method over the assets' estimated useful lives. Building and improvements are depreciated over 25 years. Laboratory, operating and office equipment and furniture are depreciated over 10 years and computer equipment over five years. Leasehold improvements are depreciated over the shorter of the estimated useful life or the lease term. Amortization of equipment under capital leases is included with depreciation expense.

    Research and development.  The Company expenses research and development costs as incurred.

    Stock based compensation.  Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), encourages, but does not require, companies to record compensation costs for stock-based employee compensation plans at fair value. The Company has elected to continue to account for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), and related Interpretations. Accordingly, compensation costs for stock options granted to employees and directors is measured as the excess, if any, of the quoted market price of the Company's stock at the date of

42


the grant over the amount an employee must pay to acquire the stock. Note 11 to the Consolidated Financial Statements contains a summary of the pro forma effects to reported net loss and per share data for 1997, 1998 and 1999 as if the Company had elected to recognize compensation cost based upon the fair value of options granted at grant date as prescribed by SFAS 123.

    Net loss per share.  Basic and diluted loss per share has been calculated using the weighted average common shares outstanding. Common equivalent shares from stock options and warrants are not included in the diluted loss per share calculations because their inclusion would be antidilutive.

    Segments.  The Company operates in a single operating segment and therefore no additional segment disclosures have been provided.

    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 these estimates.

    Recent Accounting Pronouncements.  In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative Financial Instruments and for Hedging Activities, which provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. SFAS No. 133 is effective for years beginning after June 15, 1999 and is not anticipated to have a significant impact on the Company's results of operations or financial condition when adopted.

    Included in cash equivalents at December 31, 1999 and 1998 are $13,929,000 and $23,575,000, respectively, of available-for-sale securities. The Company invests in repurchase agreement securities which are collateralized by U.S. government securities which have a market value of 102% of the investment. The securities are marked to market daily to ensure that the market value of the underlying assets remain sufficient. All available-for-sale securities have maturities of less than one year.

3. GAIN ON SALE AND LEASEBACK TRANSACTION

    In March 1998, the Company completed an agreement with a real estate investment trust for the sale and leaseback of its San Diego office/laboratory and manufacturing facility and an adjacent parcel of land. The transaction was structured as an $18,425,000 sale and a $6,000,000 convertible loan secured by specific manufacturing related building improvements. Under the terms of the agreement, the Company will lease the facility for 13 years with options to renew up to an additional 25 years. Matrix will pay an average of $2,108,000 in annual lease expense.

    This rental expense is partially offset by rental income from a portion of the facility leased to another bio-pharmaceutical company. In 1996, the Company entered into an agreement to lease out a portion of its San Diego manufacturing facility. The original lease which had a term of two years ending July 1998 was extended through July 1999 resulting in rental income of $4,472,000 during the three-year period. In September 1999, the Company entered into a three-year lease with another company which is expected to result in $2,429,000 in rental income over the three year term of the lease. Net cash from the lease and loan agreement, after the payment of the existing mortgage and escrow and other related fees, totaled approximately $13,798,000 and is being used to fund operating expenses and capital purchases. The total gain on the transaction is $5,769,000 of which $1,882,000 was recognized during the year ended December 31, 1998 as an immediate gain while the remaining balance has been deferred and is being recorded to income over the 13-year lease term.

4. OTHER INCOME

    Other income during 1998 of $6,791,000 includes the receipt of $4,000,000 from a settlement with an insurance company, $2,108,000 from the gain on sale and leaseback of the San Diego facility and $560,000 from amortization of the five year non-compete agreement.

6. DEBT AND CAPITAL LEASE OBLIGATIONS

    As noted in Footnote 3, the Company completed an agreement with a real estate investment trust for the sale and leaseback of its San Diego office/laboratory and manufacturing facility and an adjacent parcel of land. The transaction was structured as an $18,425,000 sale and a $6,000,000 convertible loan secured by specific manufacturing related building improvements. The loan bears interest at 11% per annum and the entire principal balance is due on March 26, 2002. The Company has the right prior to the maturity date to cause the lender to convert the loan to a lease agreement based upon the attainment of certain strategic alliances or joint ventures with a cumulative value in excess of $15,000,000 as measured by initial and milestone payments. In the event the Company meets certain milestones and chooses to exercise this option, rent shall be increased by $660,000 per year from approximately $1,920,000 as per the lease agreement. The lender also has the right to purchase the improvements in exchange for the outstanding principal balance of the loan up to $6,000,000 and to convert the loan to a lease agreement at any time during the loan period.

    In October 1997, the Company entered into a five-year equipment financing agreement for $10,000,000. The loan bears 9% interest per annum and matures in 2002.

    Assets purchased under debt (installment notes) or capital lease financing arrangements consist of building and related improvements, leasehold improvements, laboratory, operating, office and computer equipment with a cost of approximately $14,034,000 at December 31, 1998 and 1999. Accumulated depreciation of these assets totaled approximately $2,545,000 and $4,296,000 at December 31, 1998 and 1999, respectively. The weighted average interest rate for debt and capital lease obligations was 9.7% in 1998 and 1999. Future payments under capital leases, including interest of $20,000 total $122,000 as of December 31, 1999.

Notes to Consolidated Financial Statements (Continued)

8.  SPECIAL CHARGES

    Special charges of $4,518,000 were recorded during the third quarter of 1997 in connection with the decision to suspend further development and commercialization of AccuSite. No special charges were recorded in 1998. Management suspended the AccuSite program after the FDA notified the Company that it was not prepared to approve AccuSite as a treatment for genital warts. In September 1997, restructuring costs to conclude the clinical trials and commercial programs associated with AccuSite were accrued. The Company reduced its workforce by 63 employees, of which 46 positions related to manufacturing, resulting in severance expenses of $1,478,000. Additional expenses included the write-off of inventory related to AccuSite of $1,245,000, costs totaling $1,194,000 associated with the shut down of the Company's Northern California facilities and write-off of manufacturing equipment, the closing of clinical trials with respect to AccuSite of $414,000, and sales and marketing costs associated with AccuSite of $187,000. At December 31, 1999, the reserve had no remaining balance.

9.  LITIGATION

    On December 21, 1994, Collagen Corporation ("Collagen") filed a lawsuit against the Company in Santa Clara County Superior Court alleging misappropriation of trade secrets concerning the Company's manufacturing process for collagen and seeking unspecified damages and injunctive relief. The Company denied all allegations of the complaint and subsequently filed a cross-complaint against Collagen and Howard Palefsky, Collagen's former Chairman and Chief Executive Officer, seeking recovery of damages for defamation and violations of state law unfair competition.

    On May 23, 1997, the lawsuit between the parties was settled on mutually agreeable terms and dismissed with prejudice. All claims by and against all parties have been released. Matrix agreed that for a period of five years it shall not manufacture or sell products directly competitive with Collagen's current core products. Collagen has granted Matrix a non-exclusive license to certain Collagen intellectual property for certain non-monetary consideration.

10.  STOCKHOLDERS' EQUITY

    Preferred Share Purchase Rights Plan.  On April 17, 1995, the Company's Board of Directors adopted a Preferred Share Purchase Rights Plan under which stockholders receive one one-hundredth Series B junior participating preferred share purchase rights for each share of Matrix common stock. The rights will be distributed as a non-taxable dividend, will expire on May 28, 2005, and will be exercisable only if a person or group acquires 20% or more of the Company's common stock or announces a tender offer for 20% or more of the Company's common stock. The Board of Directors designated 150,000 shares as Series B junior participating preferred stock. As of December 31, 1999, no shares were issued or outstanding.

11.  STOCK OPTION PLANS

    1991 Directors Stock Option Plan.  The Board of Directors adopted a Directors Stock Option Plan (the "Directors Plan") in 1991. Under the Directors Plan, each individual who first becomes a non-employee member of the Board of Directors is automatically granted a non-statutory option to purchase 40,000 shares of common stock which vest over a three-year period. Each non-employee director (upon re-election to the Board) will automatically receive an option to purchase 3,000 shares of common stock which vest over a one-year period. In May 1994, an additional 200,000 shares were reserved for

issuance pursuant to the Directors Plan. In March 1997 the Director's Plan was amended such that all vested, unexercised options would remain outstanding for the full 10-year option term, regardless of whether the optionee continued to serve on the board. At the same time, an additional 250,000 shares were reserved for issuance under the Director's Plan. The aggregate maximum number of shares which may be issued under the automatic option grant program is 592,858 shares. At December 31, 1999, the total number of common shares reserved for issuance under director's stock options was 592,858, of which 289,301 were exercisable and 213,033 remain available for grant. In 1999, 18,000 shares were granted.

    1988 Restricted Stock Plan.  The Company's 1988 Restricted Stock Plan ("the Plan") permits the Company to (i) grant incentive options at 100 percent of fair value at the date of grant; (ii) grant non-qualified options at 85 percent of fair value or greater; and (iii) grant purchase rights authorizing the sale of common stock at 85 percent of fair value subject to stock purchase agreements. Options may become exercisable immediately or in installments over time as specified in each option agreement. Shares purchasable under immediately exercisable options and under purchase rights may be subject to repurchase by the Company in the event of termination of employment; the Company's repurchase right shall lapse in one or more installments over the purchaser's period of service. The term of the Plan is ten years. Options have a maximum term of ten years, except options granted to ten-percent stockholders which have a maximum term of five years. In May 1994, an additional 450,000 shares of common stock were reserved for issuance pursuant to the Plan. In May 1996, an additional 850,000 shares of common stock were reserved for issuance pursuant to the Plan. In June 1997, an additional 2,000,000 shares were reserved for issuance pursuant to the Plan. In March 1999, an additional 400,000 shares were reserved for issuance pursuant to the Plan. At December 31, 1999, the total number of common shares reserved for issuance under restricted stock options was 5,030,953 of which 391,677 remain available for grant.

    Shared Investment Program.  In March 1997, the Board of Directors authorized a special risk sharing arrangement designated as the Shared Investment Program ("the Program"). Under the Program, the Company's executive officers and other key managerial personnel were given the opportunity to purchase shares of Common Stock in an individually designated amount per participant determined by a Committee of the Board of Directors. A total of 370,000 shares were purchased under the Program by nine eligible employees at $6.25 per share, the fair market value of the Common Stock on June 25, 1997, for an aggregate consideration of $2,312,500. The purchase price was paid through the participant's delivery of a full-recourse promissory note payable to the Company. Each note bears interest at 6.69% compounded semi-annually and has a maximum term of nine years. The notes are secured by a pledge of the purchased shares with the Company. The Company recorded notes receivables from participants in this program originally for $2,312,500 in the equity section in the Consolidated Balance Sheet. In 1998, one employee repaid $31,250 and during 1999 two employees repaid a total of $135,864 resulting in a remaining balance of $2,145,386 at December 31, 1999.

    On October 29, 1997, the Board of Directors approved a resolution to offer eligible employees, including executive officers, holding stock options granted under the Plan, the opportunity to exchange their existing stock options for new options at the then current fair market value of $3.94 per share. The resolution maintains the same vesting schedule for unvested shares as was applicable for the existing stock options, but increases the service period for those shares previously vested. Vested existing options exchanged for the new options will vest 50% after six months and 50% after one year.

    The Company applies APB 25, "Accounting for Stock Issued to Employees." Pro forma information regarding net loss per share is required by SFAS 123, "Accounting for Stock-Based Compensation," and has been determined as if the Company had accounted for its employee and director stock options under the fair value method described in that Statement. The Black-Scholes option pricing model is used to calculate the fair value of these options for 1997, 1998, and 1999 with the following assumptions: dividend yield of zero % for all three years, volatility factors of 0.57 for 1997, 0.74 for 1998 and 1.03 for 1999, risk-free interest rate of 6.2% for 1997, 6.1% for 1998 and 6.7% for 1999, assumed forfeiture rate of 10.57% for 1997 and 1998, 7.65% for 1999 and an expected life of 4.0 years for all three years.

    The Black-Scholes options 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 the Company's 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. However, the Company has presented the pro forma net loss and pro forma basic and diluted net loss per common share using the assumptions noted above.

    Had compensation costs for the Company's stock option plans been determined based upon the fair value at the grant date for awards under these plans consistent with the methodology prescribed under

50


SFAS 123, the Company's net loss and net loss per share for 1997, 1998, and 1999 would have been as follows:

 
  For the Years ended December 31,
 
 
  1997
  1998
  1999
 
 
  (In thousands)

 
Net loss—as reported   $ (39,731 ) $ (21,349 ) $ (20,998 )
Net loss—pro forma   $ (41,006 ) $ (22,525 ) $ (22,807 )
Basic and diluted net loss per share—as reported   $ (1.85 ) $ (0.97 ) $ (0.94 )
Basic and diluted net loss per share—pro forma   $ (1.90 ) $ (1.02 ) $ (1.02 )

    The weighted average fair value of options granted at fair market value during 1997, 1998, and 1999, is estimated at $2.23, $2.01 and $1.36, respectively on the date of grant. The weighted average fair value of options granted at below fair market value during 1997 and 1999 is estimated at $2.19 and $0.92 on the date of grant, respectively. No options were granted at below fair market value in 1998.

    SFAS 123 is effective for options granted by the Company commencing January 1, 1995. All options granted before January 1, 1995 have not been valued and no pro forma compensation expense has been recognized. However, any option granted before January 1, 1995 that was repriced in 1996 is treated as a new grant within 1996 and valued accordingly. In addition, as compensation expense is recognized over the vesting period of the option, the proforma effect was not fully reflected until 1999.

    1999 Employee Stock Purchase Plan.  In May 1999, the "1999 Employee Stock Purchase Plan" was approved by the shareholders with an initial 700,000 shares reserved. The Plan permits eligible employees to acquire shares of the Company's common stock through periodic payroll deductions of up to 15% of total compensation. No more than 3,000 shares may be purchased on any purchase date per employee. Each offering period will have a maximum duration of 24 months. The price at which the common stock may be purchased is 85% of the lesser of the fair market value of the Company's common stock on the first day of the applicable offering period or on the last day of the respective purchase period. No shares were issued under the plan in 1999.

12. INCOME TAXES

    As of December 31, 1999, the Company had federal and state net operating loss carryforwards of approximately $182,500,000 and $40,000,000, respectively. The Company also had federal research and development tax credit carryforwards of approximately $3,900,000. The federal net operating loss and credit carryforwards will expire at various dates beginning in the year 2000 through 2019, if not utilized. The state of California net operating losses will expire at various dates beginning in 2000 through 2004, if not utilized.

    Utilization of the Company's net operating loss carryforwards and credits may be subject to an annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The Company does not expect the limitation to impact its ability to utilize all of its current net operating loss and credit carryforwards.

12. INCOME TAXES (Continued)

    Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets for financial reporting and the amount used for income tax purposes. Significant components of the Company's deferred tax assets for federal and state income taxes for the years ended December 31, 1997, 1998, and 1999 are as follows:

At December 31,

  1997

Net deferred tax assets   $   $   $  
   
 
 
 

    The net valuation allowance increased by $17,800,000, $9,200,000 and $7,300,000 in 1997, 1998 and 1999, respectively.

13. RELATED PARTIES

    During the years ended December 31, 1999, 1998, and 1997, legal fees of approximately $72,000, $244,000 and $2,816,000, respectively, were paid to Brobeck, Phleger & Harrison, a law firm in which a current director of the Company previously served as a senior partner. As of December 31, 1999 and 1998, amounts owed to Brobeck, Phleger, & Harrison were $4,000 and $16,000, respectively.

    In 1997, a director of the Company received $750,000 in exchange for promissory notes secured by a deed of trust. The notes were payable in 1998 and accrued interest at 7% per annum. In 1998, the director repaid $346,000 of principal and accrued interest of $4,000. The remaining balance of $404,000 was repaid during 1999.

    During 1997, two officers received $100,000 and $500,000, respectively, in exchange for non-interest bearing promissory notes secured by deeds of trust. During 1999, one officer received $100,000 in exchange for an interest bearing promissory note secured by a deed of trust. The outstanding loans are to be forgiven over a period of three to seven years from their inception and one loan was amended in October 1999 to be forgiven in full upon receipt of marketing approval from the FDA for Intradose. The compensation charge relating to the forgiveness is being amortized on a straight-line basis over the original note terms.

14. EMPLOYEE SAVINGS AND RETIREMENT PLAN

    The Company adopted a 401(k) savings and retirement plan in January 1990. The plan covers all eligible employees who are 21 years of age or older. In May 1996, the Board of Directors approved a matching contribution under the Company's 401(k) plan. Under this program the Company makes a matching contribution on behalf of each eligible employee equal to 50% of salary deferral contribution which began on January 1, 1997. At the end of each quarter, the Company issues new shares of its common

52


stock, using the fair market value, for its matching contribution. Company matching contributions were $424,000, $295,000 and $280,000 in 1997, 1998 and 1999, respectively.

15. FMdC LICENSE AGREEEMENT

    In September 1998, the Company entered into an agreement to license a systemic anticancer agent known as FMdC for $4 million. Under the terms of the license agreement, the Company may be obligated to make additional milestone payments and royalties on product sales.
