ITEM 1. BUSINESS

(a) GENERAL DEVELOPMENT OF BUSINESS

Titan Pharmaceuticals, Inc. ("Titan" or the "Company") is engaged in the
development of therapeutic products for the treatment of cancer, disorders of
the central nervous system ("CNS") and other serious and life-threatening
diseases.

Titan's lead product, Iloperidone, partnered with Novartis Pharma AG, is
targeted to enter phase III testing this year. Iloperidone is being
developed for the treatment of schizophrenia and related psychotic
disorders--a market expected to exceed $4 billion within two years. Also in
the CNS arena, Titan is developing a unique cell based therapeutic,
Spheramine-TM- for the treatment of Parkinson's disease, and an implantable
drug delivery system with applications in the treatment of CNS disorders.
Titan's cancer therapeutics in clinical testing include three
immunotherapeutics--CeaVac-TM-, TriAb-TM-, and TriGem-TM---that are designed
to stimulate a patient's immune system against cancer cells. Another Titan
product in development, Pivanex-TM-, is a small molecule drug that acts as a
differentiating agent and is targeted to start phase II testing this year for
non-small cell lung cancer. Collectively, this cancer product pipeline has
the potential to address more than half of all solid tumor cancers.
Additionally, Titan is developing gene therapy products for treatment of
prostate cancer, head and neck cancer, and other cancers.

The Company was incorporated in Delaware in February 1992 and has been
funded through various sources, including private placements of its
securities, as well as an initial public offering of its securities (the
"IPO") in January 1996.

A portion of Titan's operations are currently conducted through three
consolidated subsidiaries (the "Operating Companies"): Ingenex, Inc.
("Ingenex"), engaged in the development of proprietary gene-based therapies;
ProNeura, Inc., ("ProNeura"), engaged in research and development activities
relating to a polymeric implantable drug delivery technology; and Theracell,
Inc. ("Theracell"), engaged in the development of cell-based therapeutics
intended for the restorative treatment of neurological diseases and CNS
disorders. A fourth subsidiary, Trilex Pharmaceuticals, Inc., ("Trilex") was
merged with and into the Company in 1997. References to the Company and its
products herein include the operations and products of the Operating
Companies.

(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The Company operates in only one business segment.

(c) NARRATIVE DESCRIPTION OF BUSINESS

STRATEGY

The Company's strategy is to acquire and develop therapeutic product
candidates and technologies that address significant unmet medical needs in
the treatment of serious and life threatening diseases. The Company focuses
on product opportunities in clinical and late preclinical testing and may
seek licensing or other collaborative arrangements with one or more
pharmaceutical companies, which will help bear the cost of the regulatory
process and commercialization in the United States and in foreign markets.
When appropriate, the Company will retain rights to market any products which
may be successfully developed and approved for commercialization. The
Company may add additional products to its portfolio through further product
and technology licensing.

PRODUCT DEVELOPMENT PROGRAMS:

ILOPERIDONE- SCHIZOPHRENIA AND RELATED PSYCHOTIC DISORDERS

In January 1997, the Company entered into a license agreement (the "HMRI
Agreement") with Hoechst Marion Roussel, Inc. ("HMRI"), pursuant to which it
acquired an exclusive worldwide license to Iloperidone, an antipsychotic
agent in development for treatment of schizophrenia and related disorders.
Schizophrenia strikes early in life and is generally viewed as a chronic,
life-long disorder. Schizophrenia is characterized by the presence of
"positive" symptoms, such as delusions, hallucinations and disorganized
speech, and "negative" symptoms such as withdrawal and apathy. According to
the World Health Organization, approximately 45 million people worldwide have
some form of schizophrenia or a related pyschotic disorder.

Iloperidone is one of a new class of antipsychotic medications, referred
to as atypical antipsychotics, which are believed to be more effective
against most of the symptoms of schizophrenia with a lower incidence of side
effects than older medications. The results of Phase II trials, which were
completed in 1996, demonstrate that Iloperidone may provide effective
treatment against both positive and negative symptoms of schizophrenia, with
low incidence of extrapyramidal symptoms, one of the most significant side
effects associated with antipsychotic compounds currently on the market. In
the Phase II trials, Iloperidone was administered to approximately 150
patients in various doses. At the most frequently studied dose of 8 mg per
day, incidence of extrapyramidal symptoms did not differ from placebo treated
patients. At higher doses, administered in the absence of placebo
comparators, there was minimal indication of extrapyramidal symptoms. Phase
II tolerance data also supported the safety of Iloperidone at doses of up to
32 mg per day. During initial dose titration, transient postural
hypotension, a property typical of and shared by most antipsychotics, was
easily controlled by administration concurrent with food. Iloperidone is
expected to enter Phase III clinical trials in 1998.

In November 1997, Titan entered into an agreement (the "Novartis
Sublicense") with Novartis Pharma AG ("Novartis") pursuant to which Novartis
was granted a sublicense for the worldwide (with the exception of Japan)
development, manufacturing and marketing of Iloperidone. Pursuant to the
Novartis Sublicense, Novartis paid Titan approximately $17.4 million in
license fees and reimbursement of research and development expenses and made
a $5 million equity investment in Titan, and is required to make additional
milestone and royalty payments to Titan and HMRI.

The Company has been advised by Novartis that it has expanded Titan's
original Phase III clinical development plan to simultaneously pursue a
worldwide (excluding Japan) product development and registration strategy.
Novartis is in the process of manufacturing sufficient new drug substance
that will be used for all the trials and expects to commence clinical trials
in August 1998.

IMMUNOTHERAPEUTICS- COLORECTAL CANCER, BREAST CANCER, AND LUNG CANCER

The Company is engaged in development of cancer therapeutic vaccines
utilizing anti-idiotypic ("anti-id") antibody technology licensed from the
University of Kentucky Research Foundation. The anti-id therapeutics under
development are targeted at a specific epitope (site) that is primarily
present on the targeted cancer cell and is not commonly found on normal
tissue. From a molecular biological perspective the anti-id antibody is
structurally similar to the cancer epitope. When injected into a patient,
the antibody acts as a trigger for the normal immune system's response of
lymphocytes to attack target cancer cells. The amount required to elicit
this response is relatively small at two milligrams per dose, compared with
the tens or hundreds of milligrams per dose utilized in so-called
"traditional" monoclonal therapy or radio imaging.

The Company is developing three separate products that have demonstrated
an immune response in humans against antigens associated with colon cancer,
breast cancer, ovarian cancer, small cell lung cancer, melanoma and other
cancers. All three products have successfully completed Phase I clinical
trials. The products are:

- CeaVac-TM- (3H1). The Company believes this product has potential
utility in the treatment of adenocarcinomas, notably, colorectal
cancer, non-small cell lung cancer, pancreatic cancer and gastric
cancer. Carcinoembryonic antigen ("CEA") is produced by the largest
group of cancers, adenocarcinomas. In particular, this product has
received significant interest in the international oncology community,
as it is the first published report of a vaccine to consistently break
CEA immune tolerance in humans. During 1998, the Company is planning to
initiate a Phase II study in patients with colorectal cancer.

3



- TriAb-TM- (11D10). The Company believes this product has potential
utility in the treatment of breast, ovarian and non-small cell lung
cancer. During 1998, the Company is planning to initiate Phase II
studies in patients with breast cancer.

- TriGem-TM- (1A7) antibody. The Company believes this product has
potential utility in the treatment of cancers that express the GD2
ganglioside, including melanoma, small cell lung cancer and sarcoma.
During 1998, the Company is planning to initiate Phase II studies in
patients with small cell lung cancer.

A number of United States and foreign patent applications covering both
therapeutic and diagnostic applications of the anti-id antibody technology
are pending. A U.S. patent has been issued for TriGem-TM-, and claims have
been allowed for a U.S. patent of TriAb-TM-.

PIVANEX-TM-- LUNG CANCER

Pivanex, is derived from a patented analog of butyric acid, and has
demonstrated in laboratory tests the ability to destroy cancer cells through
the mechanism of cellular differentiation. Traditional cytotoxic
chemotherapeutics tend to kill cancer cells preferentially because cancer
cells divide more often and more rapidly than most normal cells.
Unfortunately, such agents may also kill rapidly dividing normal cells,
including blood cells and cells of the intestine lining, which leads to side
effects such as anemia, nausea, vomiting and risk of infection. Unlike
traditional cytotoxic chemotherapy, differentiation therapy represents a
relatively new direction in cancer research, and involves the development of
agents that, in contrast to the function of cytotoxic agents, induce cancer
cells to differentiate, mature and exhibit more normal growth properties.
Differentiation therapy may also lead to apoptosis, or what is known as
normal "programmed cell death," resulting in the destruction of the cancer
cells while sparing normal cells. Pivanex is currently completing Phase I
clinical trials and has already demonstrated a partial response in a
non-small cell lung cancer patient. During 1998, the Company is planning to
initiate Phase II studies in patients with non-small cell lung cancer.

GENE THERAPY PRODUCTS- CANCER

The Company is currently developing two potential gene therapy products
for the treatment of cancer, RB94 and MDRx1, under exclusive worldwide
licenses from the Baylor College of Medicine and the University of Illinois
at Chicago, respectively. RB94 is a gene therapy product in preclinical
development that combines a truncated variant (p94) of a tumor suppressor
gene (the "RB gene") with a viral vector. The Company believes the form of
the RB protein encoded by the RB94 gene therapy product is more effective at
causing suppression of tumor cells than the full-length RB protein, based on
data demonstrating in vitro suppression of numerous tumor types tested to
date, including tumors of the bladder, prostate, cervix, bone, breast, lung
and fibrous tissue. In addition, preliminary experiments indicate the
modified gene is effective in suppressing some cancer cell lines in vitro
that continue to contain the functional native RB gene.

The potential gene therapy product RB94 will consist of the modified RB
gene and an appropriate liposome or viral vector. The product would be
delivered directly to tumor cells through local application. In
collaboration with MD Anderson Cancer Center in Houston, Texas ("MD
Anderson"), the Company is currently testing RB94 in preclinical studies of
solid tumors in mouse models, and, if successful, the Company expects to file
an IND for a pilot clinical trial in prostate cancer patients by the end of
1998.

The Company is also developing a gene-based chemoprotective product,
MDRx1-TM-, to genetically engineer multidrug resistance into blood progenitor
(or stem) cells in order to protect these otherwise sensitive normal cells
from chemotherapy toxicity. MDRx1-TM-utilizes the human multi-drug
resistance gene (MDR1) which encodes "P-glycoprotein," a membrane protein
capable of pumping a variety of chemicals out of cells. MDRx1-TM- involves
the insertion of the MDR1 gene ex vivo into stem cells that have been removed
from cancer patients in order to render some portion of the stem cells
resistant to chemotherapeutic agents. The modified stem cells are then
reinfused into the patients where they repopulate the blood system with
chemo-resistant blood cells. The conferred resistance would potentially
allow patients to be given higher doses of anti-cancer agents than could be
given under normal circumstances (i.e., if the bone marrow was not
protected). Bone marrow suppression is the biggest dose-limiting toxicity
factor in the treatment of cancer patients because chemotherapy must be
interrupted or reduced in order to allow the bone marrow to recover.
MDRx1-TM- may allow for the administration of greater or more frequent doses
of chemotherapy while protecting the bone marrow and peripheral blood cells.
If this approach proves successful, it is also possible that MDR1 will be
utilized as a co-selective gene to help introduce and maintain other genes of
potential therapeutic value in human cells.

4



Phase I testing has been performed at MD Anderson using a preliminary
form of MDRx1-TM- with patients being treated for ovarian cancer and with
patients being treated for breast cancer to determine whether the MDR1 gene
can be introduced and maintained in humans. The clinical testing involved
introducing ex vivo the MDR1 gene in human blood stem cells extracted from
the bone marrow of cancer patients and then reintroducing the cells, which
have been made resistant to chemotherapeutic agents, where they quickly
repopulate the hematopoietic system. The results of such testing show that
the MDR1 gene has been successfully introduced into a fraction of the donor
bone marrow of many of the patients in the study. A number of issues remain
to be addressed before initiating phase II clinical studies, including
ascertaining the optimal vector for the MDR1 gene and contracting for large
scale production of the final product.

CELL THERAPY PRODUCTS- PARKINSON'S DISEASE

The Company is engaged in the research and development of cell-based
therapeutics intended for use in the restorative treatment of neurologic
diseases. A majority of neurological disorders, including Parkinson's
disease, Alzheimer's disease, stroke and epilepsy, occur when brain cells
(neurons) die. Because neurons cannot readily regenerate in response to
injury or cell death, most current pharmaceutical therapies are directed
toward amplifying the function of the remaining neurons, an approach which
becomes less effective over time as an increasing number of the neurons die.
The Company's proprietary technologies enable the development of cell-based
therapies for minimally-invasive, site specific (i.e., stereotaxic) delivery
to the central nervous system to replace or provide therapeutic factors
precisely where they are needed in order to treat the neurological disease or
disorder.

One of the Company's technologies, licensed on an exclusive worldwide
basis from New York University, involves the direct implantation into the CNS
of microscopic beads ("microcarriers"), the surfaces of which are coated with
live cells that secrete therapeutic factors useful in the treatment of
certain neurological diseases. The beads provide a matrix, or membrane-like
surface, to which cells attach and grow. The Company believes that this cell
coated microcarrier ("CCM-TM-") technology can facilitate site-specific
delivery of missing or deficient neurotransmitters, growth factors and
replacement tissue to diseased or injured areas of the brain by increasing
the survival and successful engraftment of the cells. The Company's initial
product candidate based on this technology is Spheramine-TM-, microcarriers
coated with dopamine-producing human pigmented retinal epithelial ("HPRE")
cells intended for the treatment of Parkinson's disease. Studies conducted
to date have shown improvement in hemiparkinsonian primates after
implantation of Spheramine. Further preclinical studies in primates are in
progress and the Company is also seeking a corporate partner in support of
Phase I clinical trials of this product.

Complementing CCM-TM- is a technology based on Sertoli cells, which has
been licensed exclusively on a worldwide basis from the University of South
Florida. These unique cells secrete a host of growth factors important to
the repair and resprouting of damaged neurons, and thus may be useful in
restoring function in degenerative diseases, including Parkinson's disease,
Huntington's disease, stroke, Alzheimer's disease, epilepsy and traumatic
brain injuries. Additionally, they are capable of providing an
immunologically privileged and nurturing environment to other types of cells
of interest for transplant, and thus, analogous to CCM-TM-, may facilitate
successful engraftment of such cells.

The Company's development efforts with regard to Sertoli cell technology
are at an early stage and there are a number of issues that must be resolved
including the long-term effects of cell implantation, as well as source of
cells in light of continuing controversy regarding the use of porcine tissue
in xenotransplantation due to the possibility of IN VITRO infection of human
cells with retroviruses carried by swine. Product research and development is
being conducted through the University of South Florida and contract research
and manufacturing organizations. Initial product development efforts are
focused towards early-stage Parkinson's disease and Huntington's disease.

The Company's cell therapy efforts are currently performed through
Theracell. Titan currently owns 99% of the outstanding stock of Theracell.

IMPLANTABLE DRUG DELIVERY SYSTEM

The Company is engaged in the development of drug delivery technology
with application in the treatment of a number of neurologic and psychiatric
disorders in which conventional treatment is limited by variability of drug
concentration in blood and poor patient compliance. The technology, which
has been licensed from the Massachusetts Institute of Technology ("MIT"),
consists of a polymeric drug delivery system that potentially can provide
controlled drug release over extended periods (i.e., from three months to
more than one year). The technology involves imbedding the drug

5



of interest in a polymer and extruding implantable product, which is then
implanted subcutaneously to provide systemic delivery as body fluids wash
over the implant and the drug is released. This results in a constant rate
of release similar to intravenous administration. The Company believes that
such long-term, linear release characteristics are highly desirable, avoiding
peak and trough level dosing that poses problems for many CNS and other
therapeutic agents.

The MIT technology offers significant potential benefits to patients
suffering from chronic CNS disorders, including Huntington's disease,
Parkinson's disease, schizophrenia and psychosis and chronic pain by
providing long-term, intravenous type dosing in a single administration, in
an ambulatory outpatient setting. Patients that pose compliance concerns,
including those who are impaired or whose socioeconomic circumstances hinder
compliance with traditional chronic drug administration could also
potentially benefit from this technology. There are, however, a number of
factors that will need to be addressed in the research and development phase
of any product that results from this polymer matrix technology, including
(i) flexibility in dosing; (ii) drug potency; (iii) potential negative
effects from long-term continuous drug delivery; and (iv) feasibility of
device implantation and removal. There can be no assurance that such factors
will be successfully resolved.

The Company is conducting further preclinical evaluation of prototype
products through contract research and manufacturing organizations through
its ProNeura subsidiary. Titan currently owns approximately 79% of ProNeura.

SPONSORED RESEARCH AND LICENSE AGREEMENTS

The Company is party to several agreements with research institutions,
companies, universities and other entities for the performance of research
and development activities and for the acquisition of licenses relating to
such activities.

ILOPERIDONE

Effective December 31, 1996, pursuant to the HMRI Agreement, the Company
acquired an exclusive worldwide license under United States and foreign
patents and patent applications relating to the use of Iloperidone for the
treatment of psychiatric and psychotic disorders and analgesia. The HMRI
Agreement provides for the payment of an upfront license fee in cash and
stock aggregating $9,500,000, as well as substantial additional late stage
milestone payments. See "Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations." The HMRI Agreement also
provides for the payment of royalties on net sales and requires the Company
to satisfy certain other terms and conditions in order to retain its rights
thereunder.

IMMUNOTHERAPEUTICS

The Company has acquired an exclusive, worldwide license under certain
United States and foreign patent and patent applications pursuant to a
license agreement with the University of Kentucky Research Foundation (the
"Kentucky Agreement"). These patent and patent applications relate to the
anti-idiotypic antibodies known as 3H1, 1A7 and 11D10 and their fragments,
derivatives or analogs. The Kentucky Agreement obligates the Company to fund
research at the University of Kentucky, at amounts agreed to on an annual
basis, for the five year period ending November 14, 2001. The Kentucky
Agreement provides for the payment of certain license fees totaling up to a
maximum of $370,000 as well as royalties based on net sales of licensed
products by the Company or any sublicensees. The Company must also pay all
costs and expenses incurred in obtaining and maintaining patents. The
Company must also diligently pursue a vigorous development program with
respect to the licensed technology in order to maintain its license rights
under the Kentucky Agreement.

PIVANEX

The Company has acquired from Bar-Ilan Research and Development Co. Ltd.
("Bar-Ilan") an exclusive, worldwide license to an issued United States
patent and certain foreign patents, and patent applications covering novel
analogs of butyric acid owned by Bar-Ilan University and Kupat Hulim Health
Insurance Institution (the "Bar-Ilan Agreement"). The Bar-Ilan Agreement
provides for the payment by the Company to Bar-Ilan of royalties based on net
sales of products and processes incorporating the licensed technology,
subject to minimum annual amounts commencing in 1995, as well as a percentage
of any income derived from any sublicense of the licensed technology. The
Company must also pay all costs and expenses incurred in patent prosecution
and maintenance. The minimum annual royalties for 1998 are $25,000 and
$60,000, annually thereafter.

6



The Company must also satisfy certain other terms and conditions set
forth in the Bar-Ilan Agreement in order to retain its license rights
thereunder, including the use of reasonable best efforts to bring any
products developed under the Bar-Ilan Agreement to market, and to continue
diligent marketing efforts for the life of the license, the timely
commencement of toxicology testing on small and large animals, the
development of and compliance with a detailed business plan and the timely
payment of royalty fees.

GENE THERAPY PRODUCTS

Through Ingenex, the Company is a party to several license agreements
with the University of Illinois at Chicago ("UIC") which grant the Company
the exclusive worldwide license under certain issued patents and patent
applications, including those relating to methods for preventing multi drug
resistance and the human MDR1 gene (collectively, the "UIC Licenses"). The
exclusive nature of the licenses is subject in certain instances to certain
reservations, including the use of all or part of the subject matter of the
licenses for research, education and other non-commercial purposes. In
addition, the Company's rights under the MDR1 license are subject to a
non-exclusive right granted to Burroughs-Wellcome to transfect cell lines
with the MDR1 gene, and to use the transfectants for research purposes.
Burroughs-Wellcome does not, however, have the right to sell or transfer the
transfectants or any derivatives thereof, without the written authorization
of UIC.

The UIC Licenses provide for the payment of license issue fees totaling,
in the aggregate, approximately $145,000 and a royalty to UIC based on sales
of products and processes incorporating the licensed technology. Each UIC
License also requires the payment of certain annual minimum amounts during
the time periods provided therein. Furthermore, the Company will pay to UIC
(i) royalties based on sublicensing income, (ii) a percentage of revenues
from research relating to the subject matter of each UIC License that is
performed on a contract basis for third parties and (iii) all costs and
expenses associated with patent prosecution and maintenance. The Company
must also satisfy certain other terms and conditions of the UIC Licenses in
order to retain its license rights thereunder, including the use of best
efforts to bring any products developed under the UIC Licenses to market, the
development of and compliance with a detailed business plan, obtaining all
necessary government approvals and the timely payment of license and royalty
fees. In addition, the Company has the right in all instances to elect to
assume control of patent prosecution of the licensed technology. However,
the Company may determine that the benefits of filing for patent protection
are outweighed by costs, security or other constraints. As a result, there
can be no assurances that the Company will obtain or seek patent protection
in all jurisdictions into which it sells products made under the licenses.

Through Ingenex, the Company has obtained additional exclusive,
worldwide licenses from UIC to foreign and domestic patent applications
relating to genes and genetic elements associated with (i) sensitivity to
cisplatin in human cells, (ii) neoplastic transformation and (iii)
sensitivity to chemotherapeutic drugs along with the association of kinesin
with chemotherapeutic drug sensitivity. Further development of the
technologies to which the licensed patent applications relate will depend on
the ability of the Company to enter into corporate partnering arrangements on
acceptable terms. All three of these licenses are subject to certain rights
of third parties for non-commercial research and educational purposes. These
licenses provide for the payment of license issue fees totaling $50,000,
royalties based on sales of products and processes incorporating the licensed
technology, subject to certain minimum annual amounts, and a percentage of
all revenue received from any sublicense of the licensed technology. The
obligations of the Company under these agreements are substantially similar
to those contained in the UIC Licenses.

Through Ingenex, the Company has acquired an exclusive license from MIT
(the "MIT License") under an issued patent relating to the use of MDR genes
for creating and selecting drug resistant mammalian cells. The MIT license
is subject to prior grants of (a) an irrevocable, royalty-free, nonexclusive
license granted to the United States government, (b) non-exclusive licenses
granted to Eli Lilly, Inc. ("Eli Lilly") and Genetics Institute, Inc. for
research purposes and (c) non-exclusive, commercial licenses that may be
granted pursuant to options granted to Eli Lilly and Genetics Institute, Inc.
to use aspects of the licensed technology but only to make products that do
not incorporate genes claimed in the patent, proteins expressed by such genes
or antibodies and inhibitors to such genes. The MIT License provides for the
payment of royalties based on net sales of products and processes
incorporating the licensed technology, subject to certain minimum annual
amounts, a percentage of sublicensing income arising from the license of such
products and processes, and the issuance to MIT of shares of Ingenex's Common
Stock. Under the MIT License, the Company must also use reasonable best
efforts to bring any products developed under the MIT License to market,
develop and comply with a detailed business plan and make timely payment of
license and royalty fees.

7



In October 1992, the Company acquired, through Ingenex, an exclusive,
worldwide license (the "Baylor License") under United States and foreign
patent applications assigned to Baylor College of Medicine relating to the RB
gene, including its use in conferring senescence to tumors that forms the
basis of RB94. The Baylor License provides for royalties based on net sales
of products and processes incorporating the licensed technology, subject to
certain minimum annual amounts and a percentage of sublicensing income
arising from the license of such products and processes. Under the Baylor
License, the Companymust use reasonable best efforts to bring any products
developed under the Baylor License to market, develop and comply with a
detailed business plan, fund research pursuant to the Baylor research
agreement, commence a cancer therapy research program, make timely payment of
royalty fees and pay all costs and expenses incurred in patent filing,
prosecution and maintenance.

CELL THERAPY PRODUCTS

Through Theracell, the Company has acquired an exclusive, worldwide
license under certain United States and foreign patent applications relating
to the CCM-TM- technology pursuant to a research and license agreement (the
"NYU Agreement") with New York University ("NYU"). The NYU Agreement provides
for the payment of royalties based on net sales of products and processes
incorporating licensed technology, as well as a percentage of any income it
receives from any sublicense thereof. Theracell is also obligated to
reimburse NYU for all costs and expenses incurred by NYU in filing,
prosecuting and maintaining the licensed patents and patent applications.

The Company must satisfy certain other terms and conditions of the NYU
Agreement in order to retain its license rights thereunder. These include,
but are not limited to, the use of best efforts to bring licensed products to
market as soon as commercially practicable and to diligently commercialize
such products thereafter, the use of best efforts to carry out the
performance of all efficacy, pharmaceutical, safety, toxicological and
clinical tests and to obtain all appropriate governmental approvals for the
production, use and sale of the licensed products, the development of and
compliance with a detailed business plan and the timely payment of license
and royalty fees.

In March 1996, the Company acquired, through Theracell, an exclusive,
worldwide license under United States and foreign patent applications
relating to the Sertoli cell technology pursuant to a license agreement (the
"USF Agreement") with the University of South Florida and the University of
South Florida Research Foundation, Inc. (collectively, "USF"). The USF
Agreement provides for the payment of royalties based on net sales by the
Company or any sublicensees of products and processes incorporating licensed
technology. The Company is also obligated to reimburse USF for all costs and
expenses incurred by USF in filing, prosecuting and maintaining the licensed
patent rights. The Company must satisfy certain other terms and conditions
of the USF Agreement in order to retain its license rights thereunder. These
include the development and introduction into clinical trials of at least one
product within three years of such date and an additional product every two
years thereafter until commercialization of one product, the timely payment
of license and royalties.

IMPLANTABLE DRUG DELIVERY SYSTEM

Through ProNeura, the Company has acquired from MIT an exclusive
worldwide license to certain United States and foreign patents relating to
the implantable drug delivery system (the "MIT License"). The MIT License
required the Company to invest $1,800,000 in operating capital toward
development of products and processes covered by the MIT License during the
two years ended September 1997. The exclusive nature of the MIT License is
subject to the condition that an IND application had been filed with the FDA
by December 31, 1997. Through December 31, 1997, the Company had spent
approximately $1.3 million on product development and preclinical testing and
had not fully completed the regulatory requirements for an IND application.
The Company is engaged in discussions with MIT regarding the Company's
progress to date and future development plans and does not believe the
foregoing will result in a loss of its exclusivity under the MIT license.
However, there can be no assurance to such effect. The Company must also
satisfy certain other terms and conditions set forth in the MIT License in
order to retain its license rights thereunder, including using its reasonable
best efforts to obtain the necessary regulatory approvals to conduct clinical
testing of the licensed technology and to market such products, if
successfully developed, in the United States and Europe. The MIT License
provides for the payment by the Company of royalties based on sale of
products and processes incorporating the licensed technology, as well as a
percentage of income derived from sublicenses of the licensed technology.

PATENTS AND PROPRIETARY RIGHTS

GENERAL

The Company's success will depend, in part, on its ability, and the
ability of its licensor(s), to obtain protection for their products and
technologies under United States and foreign patent laws, to preserve their
trade secrets, and to operate without infringing the proprietary rights of
third parties. The Company has obtained rights to certain patents and patent
applications and may, in the future, seek rights from third parties to
additional patents and patent applications. There can be no assurance that
patent applications relating to potential products or technologies, including
those licensed from others, or that may be licensed in the future, will
result in patents being issued, that any issued patents will afford adequate
protection or not be challenged, invalidated, infringed, or circumvented, or
that any rights granted thereunder will afford competitive advantages to the
Company. Furthermore, there can be no assurance that others have not
independently developed, or will not independently develop, similar products
and/or technologies, duplicate any of the Company's products or technologies,
or, if patents are issued to, or licensed by the Company, design around such
patents.

There can be no assurance that the validity of any of the patents
licensed to the Company would be upheld if challenged by others in litigation
or that the Company's activities would not infringe patents owned by others.
The Company could incur substantial costs in defending suits brought against
Titan or the Operating Companies or any of their licensors, or in suits in
which the Company may assert, against others, patents in which the Company
has rights. Should the Company's products or technologies be found to
infringe patents issued to third parties, the manufacture, use, and sale of
such products could be enjoined and the Company could be required to pay
substantial damages. In addition, the Company may be required to obtain
licenses to patents or other proprietary rights of third parties, in
connection with the development and use of their products and technologies.
No assurance can be given that any licenses required under any such patents
or proprietary rights would be made available on acceptable terms, if at all.

The Company also relies on trade secrets and proprietary know-how, which
it seeks to protect, in part, by confidentiality agreements with employees,
consultants, advisors, and others. There can be no assurance that such
employees, consultants, advisors, or others, will maintain the
confidentiality of such trade secrets or proprietary information, or that the
trade secrets or proprietary know-how of the Company will not otherwise
become known or be independently developed by competitors in such a manner
that the Company will have no practical recourse.

GENE THERAPY PRODUCTS

The Company is aware of a U.S. patent issued to a third party (the
"Riordan patent") relating to a multidrug resistance. The Riordan patent
describes the isolation of two DNA molecules that code for fractional
portions of the hamster protein associated with multidrug resistance (the
"hamster MDR-1 gene"). A patent licensed by Ingenex (the "Roninson patent")
describes and claims the entire human MDR-1 gene, which is the DNA that codes
for the entire protein associated with multidrug resistance in human cells.
Nonetheless, the Riordan patent claims a DNA molecule coding for a protein,
or a fragment of a protein, that is associated with multidrug resistance in
living cells, including human cells. The Riordan patent has an earlier
effective filing date than the Roninson patent, and there can be no assurance
that the Riordan patent will not be asserted against Ingenex. Thus, it may
be necessary to obtain a license under the Riordan patent to pursue
commercialization of its proposed gene therapy products utilizing the MDR-1
gene. There can be no assurance that such a license, if required, will be
made available to the Company on acceptable terms, if at all.

The Company also is aware of a U.S. patent issued to a third party (the
"Anderson patent") relating to EX VIVO gene therapy. The Anderson patent is
reported to be exclusively licensed to Genetics Therapy, Inc. The Company
believes that the Anderson patent could be asserted to cover gene
therapeutics developed by Ingenex, to the extent that the introduction of a
gene into a subject's cells is performed EX VIVO. In January 1996, it was
reported that an interference proceeding had been instituted in the U.S.
Patent and Trademark Office (the "PTO") between the issued Anderson patent
and two pending patent applications. Depending on the outcome of the
interference, it may or may not be necessary for the Company to obtain a
license from a party to the interference (or its licensee) to pursue
commercialization of its proposed gene therapy products utilizing EX VIVO
gene therapy. There can be no assurance that such a license, if required,
will be made available to the Company on acceptable terms, if at all.

The Company has received notice that three companies, Chiron
Corporation, Novartis and Introgene NV, are opposing the grant of a European
patent corresponding to the Roninson patent with claims directed to the human
MDR-1

9




gene and gene fragments. While the Company, through its licensor, intends to
vigorously respond to the oppositions, no assurance can be given as to the
scope of the claims, if any, which the European Patent Office ultimately will
find patentable.

The Company is aware of the existence of a prior art reference (European
Patent Application 0 259 031) ("EP 0 259 031"), which discloses a DNA
sequence corresponding to the sequence of the RB94 DNA molecule that is
claimed in an issued U.S. patent licensed by the Company from Baylor (the
"Baylor patent"). The Baylor patent also contains claims directed to
specific expression vectors containing these DNA molecules. Although a
patent is presumed valid, there can be no assurance that the claims of the
Baylor patent, if challenged, will not be found invalid. In any event, given
that EP 0 259 031 relates to DNA molecules but not to methods of gene
therapy, the existence of this reference alone would not, as a matter of U.S.
law, be expected to affect the patentability of claims directed to the use of
the RB94 DNA molecule in gene therapy for certain cancers, which gene therapy
claims presently are pending in a related patent application licensed by the
Company from Baylor.

CELL THERAPY PRODUCTS

The PTO has issued a U.S. patent on the core subject material underlying
the NYU License. An Australian patent on the core material of a patent
application underlying the NYU License was granted in May 1996. Prosecution
of various divisional and continuation applications and their foreign
counterparts continues satisfactorily; there can be no guarantee, however,
that additional patents will be granted. The Company is also aware of an
issued United States patent relating to a method for treating defective or
diseased cells in the mammalian CNS by grafting genetically modified donor
cells in the CNS (i.e., the brain), which cells can produce molecules (i.e.,
dopamine) in a sufficient amount to ameliorate the defect or disease. To the
extent Theracell's commercial activities include the grafting of genetically
modified donor cells, such activities could give rise to issues of
infringement of this patent.

The Company is aware of patent applications relating to use of Sertoli
cells in transplantation filed by Research Corporation Technologies (RCT).
These applications may affect validity of certain claims in the USF patent
applications. The Company and USF believe they may have certain rights in
the RCT patents. The exercise of these rights will depend on an inventorship
determination, the outcome of which is uncertain at this time.

COMPETITION

The pharmaceutical and biotechnology industries are characterized by
rapidly evolving technology and intense competition. Many companies of all
sizes, including major pharmaceutical companies and specialized biotechnology
companies, are engaged in the development and commercialization of
therapeutic agents designed for the treatment of the same diseases and
disorders targeted by the Company. Many of the competitors of the Company
have substantially greater financial and other resources, larger research and
development staffs and more experience in the regulatory approval process.
Moreover, potential competitors have or may have patent or other rights that
conflict with patents covering the Company's technologies. In certain
circumstances, it may be difficult or impossible for the Company to obtain
appropriate licenses, which would thereby hamper or prevent the
commercialization of its proposed products. The failure to obtain such
licenses could have a material adverse affect on the business, results of
operations and financial condition of Titan and such Operating Companies,
which in turn may have an adverse affect on the business, results of
operations and financial condition of the Company.

With respect to the product candidate Iloperidone, a similar class of
products is sold by Janssen Pharmaceuticals, Inc. and Eli Lilly, with other
companies continuing to develop competing compounds.

With regard to the Company's immunotherapeutic products, the Company is
aware of several companies involved in the development of cancer therapeutics
that target the same cancers as the products under development by the
Company. Such companies include Progenics, Biomira, AltaRex, Genentech,
ImClone and Glaxo-Wellcome.

With regard to its gene therapy products, the Company is aware of
several development stage and established enterprises that are exploring the
field of human gene therapy or are actively engaged in research and
development in the area of multidrug resistance, including Genetix
Pharmaceuticals, Inc. ("Genetix") and two research organizations receiving
funding from the National Institutes of Health ("NIH"). There can be no
assurance that Ingenex's MDRx1-TM- product will prove to be more efficacious
as a gene therapy than any gene therapy under development by Genetix or
either of the two research organizations. The Company is aware of other
commercial entities that have produced gene therapy products used in human
trials. Further, it is expected that competition in this field will
intensify.

10



With regard to its CNS technologies, the Company is aware of several new
drugs for Parkinson's disease that are in preclinical and clinical
development. The Company is aware that Amgen is pursuing clinical trials in
Parkinson's patients with GDNF and is collaborating with Medtronics, Inc. in
its delivery to the CNS. In addition, the Company is aware of several
well-funded public and private companies that are actively pursuing
alternative cell transplant technologies, including Somatix Therapy
Corporation ("Somatix"), CytoTherapeutics Inc. and Diacrin, Inc. The
technology under development by Diacrin, Inc. involves using antibodies to
eliminate the need for immunosuppression when transplanting fetal pig cells
into Parkinson's patients, and would directly compete with Spheramine-TM-.
There can be no assurance that any of the products under development by
Somatix, CytoTherapeutics Inc. or Diacrin, Inc., or which might be developed
by other entities, will not prove to be more efficacious in the treatment of
Parkinson's disease than the product under development by Theracell.

With regard to its implantable drug delivery system, the Company is
aware of an implantable therapeutic system being developed by ALZA
Corporation. Additionally, companies such as Medtronics, Inc. are developing
implantable pumps that could be used to infuse drugs into the CNS.

In addition to the foregoing, colleges, universities, governmental
agencies and other public and private research organizations are likely to
continue to conduct research and are becoming more active in seeking patent
protection and licensing arrangements to collect royalties for use of
technology that they have developed, some of which may be directly
competitive with the technologies being developed by the Company. These
institutions also compete with the Company in recruiting highly qualified
scientific personnel. The Company expects therapeutic developments in the
areas of oncology and hematology to occur at a rapid rate and competition to
intensify as advances in this field are made. Accordingly, the Company will
be required to continue to devote substantial resources and efforts to
research and development activities.

GOVERNMENT REGULATION

In order to obtain FDA approval of a new drug, a company generally must
submit proof of purity, potency, safety and efficacy, among others. In most
cases, such proof entails extensive clinical and preclinical laboratory
tests. The testing and preparation of necessary applications is expensive
and may take several years to complete. There is no assurance that the FDA
will act favorably or quickly in reviewing submitted applications, and
significant difficulties or costs may be encountered by the Company in its
efforts to obtain FDA approvals, which difficulties or costs could delay or
the marketing of any products which may be developed. The processing of
those applications by the FDA is a lengthy process and may also take several
years. Any future failure to obtain or delay in obtaining such approvals
could 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 any such
products could be marketed. Further, a marketed drug and its manufacturer
are subject to continued review, and later discovery of previously unknown
problems may result in restrictions on such product or manufacturer,
including withdrawal of the product from the market. In addition, new
government regulations may be established that could delay or prevent
regulatory approval of the products under development.

Among the conditions for clinical studies and IND approval is the
requirement that the prospective manufacturer's quality control and
manufacturing procedures conform to good manufacturing practices ("GMP"),
which must be followed at all times. In complying with standards set forth
in these regulations, manufacturers must continue to expend time, moneys and
effort in the area of production and quality control to ensure full technical
compliance.

The FDA may also require post-marketing testing and surveillance of
approved products, or place other conditions on their approvals. These
requirements could cause it to be more difficult or expensive to sell the
products, and could therefore restrict the commercial applications of such
products. Product approvals may be withdrawn if compliance with regulatory
standards is not maintained or if problems occur following initial marketing.
With respect to patented products or technologies, delays imposed by the
governmental approval process may materially reduce the period during which
the Company will have the exclusive right to exploit such technologies.

The procedure for obtaining FDA approval to market a new drug involves
several steps. Initially, the manufacturer must conduct preclinical animal
testing to demonstrate that the product does not pose an unreasonable risk to
human subjects in clinical studies. Upon completion of such animal testing,
an IND must be filed with the FDA before clinical studies may begin. An IND
application consists of, among other things, information about the proposed
clinical trials. Once the IND is approved (or if FDA fails to act within 30
days), the clinical trials may begin.

11



Human clinical trials on drugs are typically conducted in three
sequential phases, although the phases may overlap. Phase I trials typically
consist of testing the product in a small number of healthy volunteers or in
patients, primarily for safety in one or more doses. During Phase II, in
addition to safety, the efficacy of the product is evaluated in up to several
hundred patients and sometimes more. Phase III trials typically involve
additional testing for safety and efficacy in an expanded patient population
at multiple test sites. The FDA may order the temporary or permanent
discontinuation of a clinical trial at any time.

The results of the preclinical and clinical testing on new drugs are
submitted to the FDA in the form of a new drug application ("NDA") for new
drugs. The NDA approval process requires substantial time and effort and
there can be no assurance that any approval will be granted on a timely
basis, if at all. The FDA may refuse to approve an NDA if applicable
regulatory requirements are not satisfied. Product approvals, if granted,
may be withdrawn if compliance with regulatory standards is not maintained or
problems occur following initial marketing.

In addition, the Company's gene therapy product candidates are subject
to guidelines established by NIH, covering deliberate transfers of
recombinant DNA into human subjects conducted within NIH laboratories or with
NIH funds must be approved by the NIH Director. The Director may approve a
procedure if it is determined that no significant risk to health or the
environment is presented. The NIH has established the Recombinant DNA
Advisory Committee (the "RAC") to advise the NIH Director concerning approval
of NIH-supported research involving the use of recombinant DNA. A proposal
will be considered by the RAC only after the protocol has been approved by
the investigator's local Institutional Review Board and other committees.
Although the jurisdiction of the NIH applies only when NIH-funded research or
facilities are involved in any aspect of the protocol, the RAC encourages all
gene transfer protocols to be submitted for its review. The Company intends
to comply with RAC and NIH guidelines even when it may not be subject to them.

The Company believes it is in compliance with all material applicable
regulatory requirements.

FOREIGN REGULATORY ISSUES

Sales of pharmaceutical products outside the United States are subject
to foreign regulatory requirements that vary widely from country to country.
Whether or not FDA approval has been obtained, approval of a product by a
comparable regulatory authority of a foreign country must generally be
obtained prior to the commencement of marketing in those countries. Although
the time required to obtain such approval may be longer or shorter than that
required for FDA approval, the requirements for FDA approval are among the
most detailed in the world and FDA approval generally takes longer than
foreign regulatory approvals.

EMPLOYEES

The consolidated Company currently has 28 full-time employees. The
Company's future success depends in significant part upon the continued
service of its key scientific personnel and executive officers, as well as
those of the Operating Companies and all of such entities' continuing ability
to attract and retain highly qualified scientific and managerial personnel.
Competition for such personnel is intense and there can be no assurance that
key employees can be retained or that other highly qualified technical and
managerial personnel can be retained in the future.

None of the Company's employees is represented by a labor union. The
Company has not experienced any work stoppages and considers its relations
with its employees to be good.

RISK FACTORS

HISTORY OF OPERATING LOSSES; NEED FOR ADDITIONAL FINANCING. The Company
has experienced substantial operating losses since its inception in July
1991. As of December 31, 1997, the Company's accumulated deficit was
approximately $43.5 million. Such losses have been principally the result of
the various costs associated with research and development activities and the
Company's provision of financial, administrative, regulatory and management
services to the Operating Companies. At December 31, 1997, the Company had
working capital of approximately $24 million and believes that available
funds will enable it to fund its operations for at least 18-24 months. The
Company will be required to seek substantial additional financing to
commercialize any products that it may successfully develop. The Company has
no bank lines of credit and there can be no assurance that the Company will
be able to obtain any needed additional financing on commercially reasonable
terms.

EARLY STAGE OF DEVELOPMENT OF PROPOSED PRODUCTS. The Company's proposed
products are at various stages of development and will require significant
further research, development, testing and regulatory clearances prior to

12



commercialization. There can be no assurance that any proposed products will
be successfully developed, prove to be safe and efficacious, receive
requisite regulatory approvals, demonstrate substantial therapeutic benefits
in the treatment of any disease or condition, be capable of being produced in
commercial quantities at reasonable costs or be successfully marketed.
Accordingly, the Company must be evaluated in light of the expenses, delays,
uncertainties and complications typically encountered by newly established
biopharmaceutical businesses, many of which may be beyond the Company's
control. These include, but are not limited to, unanticipated problems
relating to product development, testing, regulatory compliance,
manufacturing, marketing and competition, and additional costs and expenses
that may exceed current estimates. There can be no assurance that the
Company will successfully develop and commercialize any products or ever
achieve profitable operations.

GOVERNMENT REGULATION. The Company's research and development activities
are, and the production and marketing of its products will be, subject to
regulation for safety and efficacy by numerous governmental authorities in
the United States and other countries. In the United States, pharmaceutical
products are subject to rigorous FDA review. The Federal, Food, Drug, and
Cosmetic Act and other federal statutes and regulations govern or influence
the research, testing, manufacture, safety, labeling, storage, recordkeeping,
approval, advertising and promotion of such products. Noncompliance with
applicable requirements can result in fines, recall or seizure of products,
refusal to permit products to be imported into or exported out of the United
States, refusal of the government to approve product approval applications or
to allow a company to enter into government supply contracts, withdrawal of
previously approved applications and criminal prosecution.

There can be no assurance that any required FDA or other governmental
approval will be granted, or if granted, will not be withdrawn. Governmental
regulation may prevent or substantially delay the marketing of the Operating
Companies' proposed products, cause them to undertake costly procedures and
furnish a competitive advantage to more substantially capitalized companies
with which they expect to compete. In addition, the extent of potentially
adverse government regulations, which might arise from future administrative
action or legislation, cannot be predicted.

RELIANCE ON PATENTS AND OTHER PROPRIETARY RIGHTS. The Company's success
will depend, in part, on its ability, and the ability of the Operating
Companies and their licensor(s), to obtain protection for their products and
technologies under United States and foreign patent laws, to preserve their
trade secrets, and to operate without infringing the proprietary rights of
third parties. The Company has obtained rights to certain patents and patent
applications and may, in the future, seek rights from third parties to
additional patents and patent applications. There can be no assurance that
patent applications relating to potential products or technologies, including
those licensed from others, or that the Company may license in the future,
will result in patents being issued, that any issued patents will afford
adequate protection or not be challenged, invalidated, infringed, or
circumvented, or that any rights granted thereunder will afford competitive
advantages to the Company. Furthermore, there can be no assurance that
others have not independently developed, or will not independently develop,
similar products and/or technologies, duplicate any of the Company's products
or technologies, or, if patents are issued to, or licensed by, the Company,
design around such patents.

There can be no assurance that the validity of any of the patents
licensed to the Company would be upheld if challenged by others in litigation
or that the Company's activities would not infringe patents owned by others.
The Company could incur substantial costs in defending itself and/or the
Operating Companies in suits brought against them or any of their licensors,
or in suits in which the Company may assert, against others, patents in which
the Company has rights. Should the Company's products or technologies be
found to infringe patents issued to third parties, the manufacture, use, and
sale of such products could be enjoined and the Company could be required to
pay substantial damages. In addition, the Company may be required to obtain
licenses to patents or other proprietary rights of third parties, in
connection with the development and use of their products and technologies.
No assurance can be given that any licenses required under any such patents
or proprietary rights would be made available on acceptable terms, if at all.

Titan also relies on trade secrets and proprietary know-how, which it
seeks to protect, in part, by confidentiality agreements with employees,
consultants, advisors, and others. There can be no assurance that such
employees, consultants, advisors, or others, will maintain the
confidentiality of such trade secrets or proprietary information, or that the
trade secrets or proprietary know-how of the Company will not otherwise
become known or be independently developed by competitors in such a manner
that the Company will have no practical recourse.

Titan is aware of an issued United States patent (as well as
corresponding patents and patent applications in foreign countries) relating
to multidrug resistance in mammalian cells. This patent claims substantially
the same subject matter as is claimed by certain issued United States patents
that have been licensed by Ingenex. The Company is also aware of an

13



issued United States patent, relating to EX VIVO gene therapy. The Company
believes that this patent claims subject matter that relates to any gene
therapeutic developed by Ingenex to the extent that the introduction of the
gene into the subject's cells is performed EX VIVO. Thus, it may be
necessary for Ingenex to obtain a license under either or both of such
patents to pursue commercialization of its proposed gene therapy products
utilizing the MDR1 gene or EX VIVO therapies, as applicable. There can be no
assurance that Ingenex will be able to obtain such licenses or that such
licenses, if available, can be obtained on terms acceptable to Ingenex.
Failure of Ingenex to obtain such licenses could have a material adverse
effect on the business, financial condition and results of operations of
Ingenex and the Company. Ingenex has received notice that three companies
are opposing the grant of a European patent which has claims directed to the
human MDR1 gene and gene fragments.

COMPETITION AND TECHNOLOGICAL CHANGE. Competition in the pharmaceutical
and biotechnology industries is intense and is expected to increase. The
Company will face competition from numerous companies that currently market,
or are developing, products for the treatment of diseases and disorders
targeted by the Company. Many of these entities have significantly greater
research and development capabilities, experience in obtaining regulatory
approvals and manufacturing, marketing, financial and managerial resources
than the Company. Acquisitions of or investments in competing biotechnology
companies by large pharmaceuticals companies could enhance such competitors'
financial, marketing and other resources. The Company also competes with
universities and other research institutions in the development of products,
technologies and processes. There can be no assurance that competitors of
the Company will not succeed in developing technologies or products that are
more effective than the Company or that will render the Company's products or
technologies noncompetitive or obsolete. In addition, certain of such
competitors may achieve product commercialization or patent protection
earlier than the Company.

DEPENDENCE UPON KEY COLLABORATIVE RELATIONSHIPS AND LICENSE AND
SPONSORED RESEARCH AGREEMENTS. The Company relies significantly on the
resources of third parties to conduct research and development. The Company's
success will depend, in part, on its ability and the ability of the Operating
Companies to maintain existing collaborative relationships and to develop new
collaborative relationships with third parties. There can be no assurance
that the Company will be successful in maintaining its existing collaborative
arrangements or that any collaborative arrangements will lead to the
successful commercialization of products.

The license agreements relating to the in-licensing of technology that
have been or may in the future be entered into by the Company or the
Operating Companies typically require the payment of an up-front license fee
and royalties based on sales of licensed products and processes under the
license and any sublicense with minimum annual royalties, the use of due
diligence in developing and bringing products to market, the achievement of
funding milestones and, in some cases, the grant of stock to the licensor.
The sponsored research agreements that have been or may in the future be
entered into by generally require periodic payments on an annual or quarterly
basis. Some agreements also may require funding or production facilities
relating to clinical research. Failure to meet financial or other
obligations under either license agreements or sponsored research agreements
in a timely manner, the rights to proprietary technology or the right to have
the applicable university or institution conduct research and development
efforts could be lost.

DEPENDENCE ON THIRD PARTIES FOR MANUFACTURING AND MARKETING ACTIVITIES.
To date, the Company has not introduced any products on the commercial
market. To conduct human clinical trials and ultimately to gain market
acceptance, the products under development must be manufactured in compliance
with regulatory requirements and at acceptable costs. It is not expected
that the Company will have the resources in the foreseeable future to
allocate to the manufacture or direct marketing of any proposed products and,
therefore, it is intended that collaborative arrangements be pursued
regarding the manufacture and marketing of any products that may be
successfully developed. There can also be no assurance that additional
collaborative arrangements to manufacture or market any proposed products
will be entered into or, in lieu thereof, that any manufacturing operations
can be successfully established or that any sales force can be successfully
implemented.

DEPENDENCE ON KEY PERSONNEL. The Company is highly dependent on the
services of Dr. Louis R. Bucalo, President and Chief Executive Officer, as
well as the other principal members of management and scientific staff of the
Company and the Operating Companies. The loss of one or more of such
individuals could substantially impair ongoing research and development
programs and the Company's ability to obtain additional financing. The
future success of the Company depends in large part upon its ability and that
of the Operating Companies to attract and retain highly qualified personnel.
This intense competition for such highly qualified personnel from other
pharmaceutical and biotechnology companies, as well as universities and
nonprofit research organizations, and may have to pay higher salaries to
attract and retain such personnel. There can be no assurance that sufficient
qualified personnel can be hired on a timely basis or

14



retained. The loss of such key personnel or failure to recruit additional
key personnel could have a material adverse effect on the Company's business,
financial condition and results of operations.

POTENTIAL ADVERSE EFFECT OF REDEMPTION OF WARRANTS. The Warrants may be
redeemed by the Company at a redemption price of $.05 per Warrant upon not
less than 30 days' prior written notice if the closing bid price of the
Common Stock shall have averaged in excess of $9.10 per share for 30
consecutive trading days ending within 15 days of the notice. Redemption of
the Warrants could force the holders (i) to exercise the Warrants and pay the
exercise price therefor at a time when it may be disadvantageous for the
holders to do so, (ii) to sell the Warrants at the then current market price
when they might otherwise wish to hold the Warrants, or (iii) to accept the
nominal redemption price which, at the time the Warrants are called for
redemption, is likely to be substantially less than the market value of the
Warrants.

CURRENT PROSPECTUS AND STATE REGISTRATION TO EXERCISE WARRANTS. Holders
of Warrants will be able to exercise the Warrants only if (i) a current
prospectus under the Securities Act relating to the shares of Common Stock
underlying the Warrants is then in effect and (ii) such securities are
qualified for sale or exempt from qualification under the applicable
securities laws of the states in which the various holders of Warrants
reside. Although the Company has undertaken and intends to use its best
efforts to maintain a current prospectus covering the shares underlying the
Warrants following completion of the Offering to the extent required by
Federal securities laws, there can be no assurance that the Company will be
able to do so. The value of the Warrants may be greatly reduced if a
prospectus covering the shares issuable upon the exercise of the Warrants is
not kept current or if the securities are not qualified, or exempt from
qualification, in the states in which the holders of Warrants reside.
Persons holding Warrants who reside in jurisdictions in which such securities
are not qualified and in which there is no exemption will be unable to
exercise their Warrants and would either have to sell their Warrants in the
open market or allow them to expire unexercised. If and when the Warrants
become redeemable by the terms thereof, the Company may exercise its
redemption right even if it is unable to qualify the underlying securities
for sale under all applicable state securities laws.

SHARES ELIGIBLE FOR FUTURE SALE. Future sales of the Company's Common
Stock by existing stockholders pursuant to Rule 144 under the Securities Act,
pursuant to an effective registration statement or otherwise, could have an
adverse effect on the price of the Company's securities.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.

The following discussion should be read in conjunction with the
Consolidated Financial Statements and Notes thereto appearing elsewhere in
this report.

The following discussion contains certain forward-looking statements,
within the meaning of the "safe harbor" provisions of the Private Securities
Reform Act of 1995, the attainment of which involves various risks and
uncertainties. Forward-looking statements may be identified by the use of
forward-looking terminology such as "may," "will," "expect," "believe,"
"estimate," "anticipate," "continue," or similar terms, variations of those
terms or the negative of those terms. The Company's actual results may
differ materially from those described in these forward-looking statements
due to, among other factors, the results of ongoing research and development
activities and preclinical testing, the results of clinical trials and the
availability of additional financing through corporate partnering
arrangements or otherwise.

OVERVIEW

Since its inception, the Company's efforts have been principally devoted
to acquiring technologies, research, clinical development, securing patent
protection and raising capital. At December 31, 1997, the Company had an
accumulated deficit of approximately $43,500,000, resulting from expenditures
for research and development and general and administrative activities
including professional fees.

In December 1996, Titan and HMRI entered into the HMRI License, pursuant
to which, the Company paid, during 1997, an up-front license fee of
$9,500,000, payable as follows: (i) $2,000,000 in cash in January 1997; (ii)
$5,500,000 through the issuance 594,595 shares of common stock (the "HMRI
Shares") in January 1997; (iii) and $2,000,000 in cash in July 1997. Pursuant
to the HMRI License, the Company was obligated to pay to HMRI the difference
between $5,500,000 and the net proceeds received by HMRI upon sale of the
HMRI Shares. In February 1998, HMRI sold the HMRI Shares for net proceeds of
approximately $2,456,000. Accordingly, in March 1998, the Company paid to
HMRI the approximately $3,044,000 due. As the Company could have been liable
for the entire $5,500,000, it was not included in stockholders' equity. Upon
the payment to HMRI, approximately $2,456,000 was credited to stockholders'
equity. The HMRI License also provides for substantial future late stage
milestone payments to HMRI, as well as royalty payments on net sales, if any.

In November 1997, Titan and Novartis entered into the Novartis
Sublicense pursuant to which the Company granted Novartis a sublicense for
the worldwide (with the exception of Japan) development, manufacturing and
marketing of Iloperidone. Pursuant to the Novartis Sublicense, Novartis paid
to the Company an up-front license fee of $20,000,000, of which $5,000,000
represents an equity investment in a newly authorized series of convertible
preferred stock (the "Preferred Shares"). In addition, approximately $2.4
million in cash was paid by Novartis as reimbursement of research and
development costs incurred by the Company. The Novartis Sublicense provides
for future payments by Novartis contingent upon the achievement of regulatory
milestones as well as royalty payments on net sales, if any. Novartis has
assumed the clinical development, registration and marketing costs of
Iloperidone. The Preferred Shares were issued pursuant to an agreement (the
"Stock Purchase Agreement") which provides for conversion of such shares into
the Company's Common Stock at the option of Novartis at any time after
January 29, 1999. The conversion price will be equal to the market price
during a period to be specified within the first two fiscal quarters of 1999
and is subject to a floor of $7.50 and a ceiling of $9.00. Accordingly, upon
conversion of the Preferred Shares, the Company will issue a minimum of
555,555 and a maximum of 666,666 shares of Common Stock. The Stock Purchase
Agreement provides that such shares may not be sold, transferred or assigned
prior to November 19, 1999.

Titan has assessed the likely impact on its business of the Year 2000
Issue and does not believe that this issue will present a material problem
for the Company's business or will require significant resources to address.

The Company's business is subject to significant risks including, but
not limited to, the success of its product development efforts, obtaining and
enforcing patents important to the Company's business, competition from other
products and the lengthy as well as expensive regulatory approval process.
There can be no assurance that the Company will have the resources necessary
to conduct the several phases of clinical testing in human subjects necessary
to complete the development and commercialization of any of its products.
The Company's strategy will continue to be to seek public or private
financing through the sale of securities, corporate partnering arrangements
and the licensing of product or technology rights, in order to fund product
development activities and enable the Company to continue to expand its
product portfolio through acquisitions. There can be no assurance that
financing from such sources or others will be available. Additional
expenses, delays, and losses of opportunity that may arise out of these and
other risks could have a material adverse impact on the Company's financial
condition and results of operations.


RESULTS OF OPERATIONS

FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

Total revenues for the year ended December 31, 1997 ("1997") were
$17,500,000 compared with $259,000 for

17



the year ended December 31, 1996 ("1996"). The increase was attributable
to one-time, up-front license fees related to the license of Iloperidone to
Novartis.

Through December 31, 1997, research and development expenses totaled
$47,076,000, and general and administrative expenses totaled $18,242,000.
Research and development expenses for 1997 were $18,810,000 (including
$9,500,000 of acquired in-process research and development), as compared to
$5,567,000 for 1996, an increase of $13,243,000, or 238%. The increase
resulted from the expansion of the Company's development activities,
including the acquisition and further development of Iloperidone. General and
administrative expenses for 1997 were $6,514,000, as compared to $5,264,000
for 1996, an increase of $1,250,000, or 24%. The increase reflects
additional administrative support for the Company's expanded development
activities. General and administrative expenses have declined as a
percentage of total operating expenses, from 49% to 26% in 1996 and 1997
respectively.

Other income/(expense), for 1997 was $8,415,000 compared with
$(2,294,000) for 1996. Other income for 1997 includes approximately
$8,400,000 representing the proceeds from the sale of Ingenex's GSX
technology, and interest income of $666,000. Other income for 1996 includes
interest income of $716,000. Interest expense was $227,000 during 1997 as
compared to $2,011,000 for 1996. Approximately $1,408,000 of the 1996
expense reflects a non-recurring charge due to the repayment in January 1996
of notes issued in a bridge financing ("Bridge Notes"). This non-recurring
charge represents the unamortized portion of the $1,800,000 debt discount and
$458,000 of debt issuance costs relating to the Bridge Notes. Other income
for 1997 and 1996 also includes $591,000 and $999,000, respectively, of
losses representing the Company's share of Ansan's losses.

The Company had net income of $592,000 during 1997 compared with a net
loss of $12,856,000 during 1996. None of the Company's products, however,
have yet been commercialized, and the Company does not expect to generate any
significant revenue for the foreseeable future. The Company expects to incur
substantial research and development costs in the future as a result of
funding ongoing (i) product development programs, (ii) manufacturing of
products for use in clinical trials, (iii) patent and regulatory related
expenses, and (iv) preclinical and clinical testing. The Company also
expects that general and administrative costs necessary to support such
research and development activities will increase. The Company will also
seek to identify new technologies and/or product candidates for possible
in-licensing or acquisition. Accordingly, the Company expects to incur
increasing operating losses for the foreseeable future. There can be no
assurance that the Company will ever achieve profitable operations.

Upon completion of the Company's IPO, in January 1996, the Company's
previously outstanding shares of preferred stock were converted automatically
into shares of common stock at adjusted conversion prices per common share
less than the public offering price per common share. The deemed benefit to
the preferred stockholders approximated $5,400,000, which deemed benefit was
recorded by offsetting charges and credits to additional paid-in capital at
the time of conversion. There was no effect on net loss from the mandatory
conversion. However, the amount increased the loss allocable to common stock
in the calculation of net loss per share in the period of the conversion.

FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995

Total revenues for 1996 were $259,000 and $140,000 for the year ended
December 31, 1995 ("1995") from National Institutes of Health grants.

Research and development expenses for 1996 were $5,567,000, as compared
to $5,888,000 for 1995, a decrease of $321,000, or 5%. The decrease reflects
the deconsolidation of Ansan effective August 1995, the cessation of
operations by Geneic Sciences in September 1995 and the completion of certain
sponsored research for Ingenex in 1995, offset by an in-process research and
development charge of $686,000 in 1995, the addition of ProNeura in late 1995
and Trilex in May 1996.

General and administrative expenses for 1996 were $5,264,000, as
compared to $3,658,000 for 1995, an increase of $1,606,000, or 44%. The
increase includes $805,000 reflecting the addition of Trilex in May 1996, as
well as $688,000 of expenses incurred by Ingenex in conjunction with a
financing that was terminated.

As a result of the foregoing expenses, the Company incurred an operating
loss of $12,856,000 during 1996 compared with $11,693,000 during 1995.

Other income includes interest income of $716,000 during 1996 as
compared to $68,000 during 1995. This increase was a result of a substantial
increase in the amount of cash and short-term investments subsequent to the
Company's IPO in January 1996 and a private placement completed in August
1996. Interest expense was $2,011,000 during 1996 as compared to $1,899,000
for 1995. Other income for 1996 and 1995 also includes $999,000

18



and $457,000, respectively, of losses representing the Company's share of
Ansan's losses.

LIQUIDITY AND CAPITAL RESOURCES

The Company has funded its operation from inception primarily through
private placements of its securities, as well as the IPO. During 1997, the
Company also received approximately $25,861,000 from up-front license fees in
the Novartis transaction and the sale of the GSX technology. The Company is
currently negotiating a $5,000,000 bank line of credit.

Titan has entered into various agreements with research institutions,
universities, and other entities for the performance of research and
development activities and for the acquisition of licenses related to those
activities. The aggregate commitments the Company has under these
agreements, including minimum license payments, for the next 12 months is
approximately $1,302,000. Certain of the licenses provide for the payment of
royalties by the Company on future product sales, if any. In addition, in
order to maintain license and other rights while products are under
development, the Company must comply with customary licensee obligations,
including the payment of patent related costs and meeting project-funding
milestones.

The Company expects to continue to incur substantial additional
operating losses from costs related to continuation and expansion of research
and development, clinical trials, and increased administrative and fund
raising activities over at least the next several years. While the Company
believes it has sufficient working capital to sustain its planned operations
beyond the end of 1998, the Company may seek additional financing sooner,
depending on numerous factors including, but not limited to, the progress of
the Company's research and development programs, the results of clinical
studies,

19



technological advances, determinations as to the commercial potential of the
Company's products, and the status of competitive products. In addition,
certain expenditures will be dependent on the establishment of collaborative
relationships with other companies, the availability of financing, and other
factors. In any event, the Company anticipates that it will require
substantial additional financing in the future. There can be no assurance as
to the availability or terms of any required additional financing, when and
if needed.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

Section 16(a) of the Securities Exchange Act of 1934, as amended,
requires the Company's executive officers, directors and persons who
beneficially own more than 10% of a registered class of the Company's equity
securities to file with the Securities and Exchange Commission initial
reports of ownership and reports of changes in ownership of common stock and
other equity securities of the Company. Such executive officers, directors,
and greater than 10% beneficial owners are required by SEC regulation to
furnish the Company with copies of all Section 16(a) forms filed by such
reporting persons.

Based solely on the Company's review of such forms furnished to the
Company and written representations from certain reporting persons, the
Company believes that all filing requirements applicable to the Company's
executive officers, directors and greater than 10% beneficial owners were
complied with, with the exception of Richard Allen who filed a Form 4 two
months late and Lindsay Rosenwald who filed a Form 5 one month late.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

In March and April 1993, the Company borrowed an aggregate of $700,000
from Dr. Lindsay A. Rosenwald, the co-founder and a director of the Company.
See "Item 12. Security Ownership of Certain Beneficial Owners and
Management." The loan was evidenced by 10% promissory notes payable on
demand. Dr. Rosenwald received warrants that are currently exercisable to
purchase an aggregate of 20,355 shares of Common Stock at an exercise price
of $4.50 per share. In June 1995, the notes, together with accrued interest,
were cancelled in consideration of the issuance to Dr. Rosenwald of shares of
Series A Preferred Stock which subsequently converted into 215,135 shares of
Common Stock.

In April and May 1993, Dr. Rosenwald made loans to the Company in the
aggregate principal amount of $1,014,000. Such loans were repaid, together
with accrued interest at the rate of 7% per annum, from the proceeds of the
private placement of Series A Preferred Stock described below.

In January 1995, the Company agreed to issue warrants to purchase an
aggregate of 7,395 shares of Common Stock at an exercise price of $3.25 per
share to Ray Dirks Research ("RDR") or its designees for services rendered in
connection with a license transaction. Michael Hsu, a director of the
Company, serves as a consultant to RDR and received one-half of such warrants.

In February 1995, Paramount Capital, Inc. ("Paramount") acted as
placement agent in connection with the Company's private placement of Series
B Preferred Stock. Paramount received $103,125 in commissions and a $45,375
expense allowance for services rendered in connection with such private
placement. In addition, designees of Paramount received Series B Preferred
Stock purchase warrants that currently represent warrants to purchase an
aggregate of 46,350 shares of Common Stock at an exercise price of $3.92 per
share. Dr. Rosenwald serves as the President and Chairman of Paramount and
received warrants to purchase 17,961 of such shares.

Between August and October 1995, The Aries Domestic Fund L.P. and The
Aries Trust loaned the Company an aggregate of $250,000 evidenced by the
promissory notes (the "Investor Notes") which bore interest at the rate of
12% per annum and were payable on the earlier of the closing of an initial
public offering or one year from the date of issuance. In accordance with
their terms, the principal amount of the Investor Notes was converted into
$250,000 principal amount of 10% promissory notes

26



(the "Bridge Notes") and 125,000 Class A Warrants as part of a bridge
financing completed in October 1995. Accrued interest on the Investor Notes
was repaid in January 1996. Repayment of the principal and accrued interest
on the Bridge Notes was made upon completion of the Company's initial public
offering in January 1996. Dr. Rosenwald is the President of the general
partner of The Aries Domestic Fund L.P. and serves as investment manager for
The Aries Trust.

The Company believes that all of the transactions set forth above were
made on terms no less favorable to the Company than could have been obtained
from unaffiliated third parties. The Company has adopted a policy that all
future transactions, including loans, between the Company and its officers,
directors, principal shareholders and their affiliates will be approved by a
majority of the Board of Directors, including a majority of the independent
and disinterested outside directors on the Board of Directors, and will
continue to be on terms no less favorable to the Company than could be
obtained from unaffiliated third parties.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS




The Board of Directors and Stockholders
Titan Pharmaceuticals, Inc.

We have audited the accompanying consolidated balance sheets of Titan
Pharmaceuticals, Inc. (a development stage company) as of December 31, 1997
and 1996, and the related consolidated statements of operations,
stockholders' equity (net capital deficiency), and cash flows for each of the
three years in the period ended December 31, 1997 and for the period from
July 25, 1991 (commencement of operations) to December 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Titan
Pharmaceuticals, Inc. (a development stage company) at December 31, 1997 and
1996, and the consolidated results of its operations and its cash flows for
each of the three years in the period ended December 31, 1997 and for the
period from July 25, 1991 (commencement of operations) to December 31, 1997,
in conformity with generally accepted accounting principles.

TITAN PHARMACEUTICALS, INC.
(A DEVELOPMENT STAGE COMPANY)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY AND ITS SEVERAL DEVELOPMENT STAGE SUBSIDIARIES

Titan Pharmaceuticals, Inc. (the "Company" or "Titan"), was incorporated
in February 1992 in the State of Delaware. Titan is a biopharmaceutical
company developing proprietary therapeutics for the treatment of central
nervous system disorders, cancer and other serious and life-threatening
diseases. Titan conducts a portion of its operation through three development
stage biotechnology companies: Ingenex, Inc. ("Ingenex"), Theracell, Inc.
("Theracell") and ProNeura, Inc. ("ProNeura"), collectively, (the "Operating
Companies"). Trilex Pharmaceuticals, Inc. ("Trilex") was incorporated in May
1996, as a wholly owned subsidiary of the Company, to engage in the
development of cancer therapeutic vaccines utilizing anti-idiotypic antibody
technology. In August 1997, Trilex was merged (the "Trilex Merger") with and
into Titan.

INGENEX, INC.

Ingenex is engaged in the development of gene-based therapeutics and the
discovery of medically important genes for the treatment of cancer and viral
diseases. In September 1994, Ingenex issued shares of its Series B
convertible preferred stock to a third party for $1,241,032, net of issuance
costs. In June 1996, Ingenex issued 981,818 shares of common stock to the
Company, converting $5,400,000 of debt payable. Also in June 1996, and in
consideration of a payment to Ingenex of $100,000, Ingenex issued to the
Company an option to purchase an additional 315,789 shares of common stock
which will have an exercise price per share equal to the initial public
offering price of Ingenex common stock and an additional option and a right
of first refusal with respect to future issuances of common stock in order
for the Company to maintain ownership of a majority of the outstanding common
stock. The option expires one year from the date of the consummation of the
initial public offering of Ingenex common stock. In June 1997, Ingenex sold
its GSX System (the "GSX Sale"), a research technology, and certain fixed
assets to Pharmaceutical Product Development, Inc. ("PPD") for $8,722,500 in
cash and the assumption of certain capital lease liabilities and recognized a
gain of $8,361,220. At December 31, 1997, the Company owned 81% of Ingenex,
assuming the conversion of all preferred stock to common.

THERACELL, INC.

Theracell was incorporated in November 1992 to engage in the development
of novel treatments for various neurologic disorders through the
transplantation of neural cells and neuron-like cells directly into the
brain. The Company's ownership in Theracell was 85% through November 1995,
at which time the Company entered into an agreement with the minority
stockholders of Theracell pursuant to which 140,000 shares of the Company's
stock were issued in exchange for all the outstanding shares of Theracell
common stock held by them. In connection with the issuance of the 140,000
shares, the Company recorded a charge for acquired in-process research and
development of $686,000. In November 1995, the former minority stockholders
of Theracell were granted an option to acquire 5% of the issued and
outstanding capital stock of Theracell. These options can be exercised at a
price of $1.59 per share within a period of three years from January 18,
1996. Commencing thirty days after the date Theracell's shares are first
publicly traded, the Theracell options may be subject to redemption under
certain conditions by Theracell on thirty days' written notice at a
redemption price of $0.05 per share if the closing price of Theracell's
common stock for any thirty consecutive trading days ending within fifteen
days of the notice of redemption averages in excess of $3.18 per share. At
December 31, 1997, the Company owned 99% of Theracell.

PRONEURA, INC.

ProNeura was incorporated in October 1995 to engage in the development of
cost effective, long term treatment solutions to neurologic and psychiatric
disorders through an implantable drug delivery system. At December 31, 1997,
the Company owned 79% of ProNeura.

TITAN PHARMACEUTICALS, INC.
(A DEVELOPMENT STAGE COMPANY)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of
Titan and the majority owned Operating Companies. All significant
intercompany transactions and accounts have been eliminated in consolidation.
The financial statements of the Company include the results of Ingenex from
the date Ingenex was incorporated (July 25, 1991), as the entities were under
common control.

The activities of the Company have primarily consisted of establishing
offices and research facilities, recruiting personnel, conducting research
and development, preclinical and clinical studies, performing business and
financial planning and raising capital. Accordingly, the Company is
considered to be in the development stage. The Company has incurred losses
since inception of $43.5 million and expects to incur increasing losses and
require additional financial resources to achieve commercialization of its
products.

The Company anticipates working on a number of long-term development
projects which will involve experimental and unproven technologies. The
projects may require many years and substantial expenditures prior to
commercialization. Therefore, the Company will need to obtain additional
funds from the issuance of equity or debt securities, from corporate
partners, or from other sources to continue its research and development
activities, fund operating expenses, pursue regulatory approvals and build
production, sales and marketing capabilities, as necessary. Management
believes that sufficient capital will be available to achieve planned
business objectives, including supporting certain preclinical development and
clinical testing, through at least 1998.

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

The Company considers all highly liquid investments with an original
maturity of 90 days or less to be cash equivalents. Cash equivalents include
$20,124,561 and $896,970 in money market funds at December 31, 1997 and 1996,
respectively. The Company's investment policy is to maintain liquidity and
ensure safety of principal.

At December 31, 1997, short term investments is comprised of auction rate
preferred stock (preferred stock investments in money market funds),
classified as "available for sale." Such investments are carried at cost,
which approximates their fair market value. The Company has not realized any
gains or losses on its investments.

FURNITURE AND EQUIPMENT

Furniture and equipment is stated at cost and is depreciated using the
straight-line method over the estimated useful lives of the assets ranging
from three to five years.

REVENUE RECOGNITION

Revenue consists of revenue from up-front license fees which have been
recognized in accordance with the related license agreement and government
grants which support the Company's research effort in specific research
projects. These grants generally provide for reimbursement of approved costs
incurred as defined in the various agreements.

SPONSORED RESEARCH

Research and development expenses under sponsored research arrangements
are recognized as the related services are performed, generally ratably over
the period of service. Payments for license fees are expensed when paid.

STOCK-BASED COMPENSATION

In accordance with the provisions of Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"),
the Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and related

F-12

(A DEVELOPMENT STAGE COMPANY)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

interpretations and to adopt the "disclosure only" alternative described in
SFAS 123 in accounting for its employee stock option plans. Under APB 25, if
the exercise price of the Company's employee stock options equals or exceeds
the fair value of the underlying stock on the date of grant, no compensation
expense is recognized.

NET INCOME (LOSS) PER SHARE

Effective December 31, 1997, the Company adopted statement of Financial
Accounting Standards No. 128 "Earnings Per Share" ("SFAS No. 128"). SFAS No.
128 requires the presentation of basic earnings (loss) per share and diluted
earnings (loss) per share, if more dilutive, for all periods presented. In
accordance with SFAS No. 128, basic net income (loss) per share has been
computed using the weighted-average number of shares of common stock
outstanding during the period. Diluted earnings per share includes any
dilutive effects of options, warrants and convertible securities.

The following table sets for the computation of basic and diluted earnings
per share:



1997 1996 1995
----------- ----------- -----------

Weighted-average shares of common stock
outstanding during the period(1) 13,002,050 10,936,046 6,719,634
Effect of dilutive securities:
Employee stock options 284,951 -- --
Unit purchase options 20,615 -- --
Convertible preferred stock 104,110 -- --

Shares used in computation of diluted
earnings per share 13,476,644 10,936,046 6,719,634
----------- ----------- -----------
----------- ----------- -----------


(1) Includes in 1995, on a pro forma basis, 5,293,585 shares of preferred
stock (on an as-if-converted to common basis) which automatically converted
to common stock upon the closing of the Company's initial public offering.

Potentially dilutive securities not included in the computation of diluted
earnings per share:

Options to purchase 1,066,799 shares of common stock at various prices per
share were outstanding during 1997 but were not included in the computation
of diluted earnings per share because the exercise prices of the options were
greater than the average market price of the common shares and, therefore,
the effect would be antidilutive.

Options to purchase 307,200 Units (one share of common stock and one Class A
warrant) at $10.42 per unit were outstanding during 1997 but were not
included in the computation of diluted earnings per share because the
exercise price of the units was greater than the average market price of the
common shares and, therefore, the effect would be antidilutive.

Warrants to purchase 7,031,986 shares of common stock at $6.20 per share were
outstanding during 1997 but were not included diluted earnings per share
because the exercise price of the warrants was greater than the average
market price of the common shares and, therefore, the effect would be
antidilutive.

TITAN PHARMACEUTICALS, INC.
(A DEVELOPMENT STAGE COMPANY)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company issued 222,400 shares of a new class of preferred stock (the
"Series C Preferred") (see Note 7) in connection with the Trilex Merger. The
preferred stock will automatically convert to common stock, only if certain
development milestones are achieved, within certain timeframes. As the
milestones have not yet been met, the Series C Preferred is not included in
the computation of diluted earnings per share in 1997.

Had the Company been in a net income position, diluted earnings per share
in 1996 and 1995 would have included the shares used in the computation of
basic net loss per share for 1996 and for 1995 and the dilutive effect of
10,163,950 and 930,191 shares, respectively, related to outstanding options
and warrants (prior to the application of the treasury stock method).

For purposes of computing per share data for the year ended December 31,
1996, the net loss has been increased by a $5,431,871 deemed dividend (see
Note 7).

Basic net loss per share for the year ended December 31, 1995 has been
retroactively restated to apply the requirements of Staff Accounting Bulletin
No. 98, issued by the SEC in February 1998 ("SAB 98"). Under SAB 98, certain
shares of common stock and options and warrants to purchase shares of common
stock issued at prices substantially below the per share price of shares sold
in the Company's initial public offering previously included in the
computation of shares outstanding for periods prior to the Company's initial
public offering are now excluded from the computation.

USE OF ESTIMATES

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

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In 1997, Statement of Financial Accounting Standards No. 130 ("SFAS 130"),
"Reporting Comprehensive Income," was issued and is required to be adopted by
the Company in 1998.

In 1997, Statement of Financial Accounting Standards No. 131 ("SFAS 131"),
"Disclosure About Segments of an Enterprise and Related Information," was
issued and is required to be adopted by the Company in 1998.

The Company expects the adoption of these statements will not impact
results of operations or financial position, but will require additional
disclosure.

2. INVESTMENT IN ANSAN PHARMACEUTICALS, INC.

Ansan was a majority-owned consolidated subsidiary until its public
offering in August 1995, at which time it became an equity method investee of
the Company.

In November 1997, the shareholders of Ansan Pharmaceuticals, Inc.
("Ansan") approved an Agreement and Plan of Reorganization and Merger between
Ansan and Discovery Laboratories, Inc. ("Discovery"), a development stage
biotechnology company, pursuant to which Discovery was merged with and into
Ansan (the "Ansan Merger").

Pursuant to the Ansan Merger, the Company acquired an exclusive worldwide
license to Ansan's butyrate compounds for anti-cancer and certain other
indications in exchange for the Company's payment of a 2% royalty on net
sales and the Company's transfer to Ansan of all of its equity holdings in
Ansan. Upon completion of the Merger, Ansan repaid approximately $1,170,000
of outstanding indebtedness to the Company.

4. SPONSORED RESEARCH AND LICENSE AGREEMENTS

The Operating Companies have entered into various agreements with research
institutions, universities, and other entities for the performance of
research and development activities and for the acquisition of licenses
related to those activities. Expenses under these agreements totaled
$2,104,105, $1,827,000 and $1,024,000 in the years ended December 31, 1997,
1996 and 1995, respectively.

At December 31, 1997, the annual aggregate commitments the Company has

investments.

5. INGENEX TECHNOLOGY FINANCING AGREEMENT

In January 1995, Ingenex assigned its rights under certain of its
technology license agreements to a capital management partnership in exchange
for $2,000,000. Ingenex licensed back the technology for research and
development purposes and agreed to make monthly payments of $25,000 through
July 1995 and $60,060 from August 1995 through January 1999. Each payment
included implicit interest at approximately 11.6% per annum. At the end of
the payment term, the assigned license rights could be reacquired by Ingenex
for $1.00. As part of the financing agreement, the Company issued to the
capital management partnership a warrant to purchase 112,375 shares of the
Company's Common Stock at a price of $3.56 per share. The warrant expires
January 31, 2002. The capital management partnership has agreed to not sell,
assign, or transfer any securities of the Company without prior written
consent of the Company's underwriter. In connection with the technology
financing the Company issued a finder and a director

warrants to purchase an aggregate of 7,395 shares of the Company's common
stock at an exercise price of $3.25 per share. The warrants expire in

7. STOCKHOLDERS' EQUITY

PREFERRED STOCK

In August 1997, Trilex was merged by and into Titan. In connection with
this transaction, in October 1997, the Company issued 222,400 shares of
Series C preferred stock to certain members of Trilex management and certain
consultants of Trilex. The Series C preferred stock will automatically
convert to common stock, on a one-to-one basis, only if certain development
milestones are achieved, within certain timeframes. Holders of Series C
preferred stock are entitled to receive dividends, when, as and if declared
by the board of directors ratably with any declaration or payment of any
dividend on the common stock or other junior securities of the Company. The
series C preferred stock has a liquidation preference equal to $0.01 per
share. No value was assigned to the Series C preferred stock in the
accompanying financial statements.

In November 1997, Titan issued to Novartis Pharma AG ("Novartis") 606,061
shares of Series D convertible preferred stock (the "Series D Shares"),
pursuant to an agreement by which Titan granted certain technology rights to
Novartis (see Note 11). The Series D Shares were issued pursuant to a stock
purchase agreement which provides for conversion of such shares into the
Company's Common Stock at the option of Novartis at any time after January
29, 1999. The conversion price will be equal to the market price during a
period to be specified within the first two fiscal quarters of 1999 and is
subject to a floor of $7.50 and a ceiling of $9.00. Accordingly, upon
conversion of the Series D Shares, the Company will issue a minimum of
555,555 and a maximum of 666,666 shares of Common Stock. The stock purchase
agreement provides that such shares may not be sold, transferred or assigned
prior to November 19, 1999. Holders of Series D preferred stock are entitled
to receive dividends, when, as and if declared by the board of directors
ratably with any declaration or payment of any dividend on the common stock
or other junior securities of the Company. The Series D Preferred Stock has
a liquidation preference equal to $0.05 per share. Holders of Series D
preferred stock are entitled to vote on a one-to-one basis with the common
stock of the Company.

Each share of Series A and Series B preferred stock outstanding prior to
the Company's IPO was originally convertible into (and carried voting rights
equal to) one share of common stock. In October 1995, pursuant to the terms
of the Series B preferred stock agreement and in contemplation of the IPO,
the board of directors and stockholders approved a change in the conversion
ratio of Series A and Series B preferred stock providing that in the event of
an IPO of common stock on or before March 31, 1996, each share of Series A
and Series B preferred stock would automatically be converted into
1.4310444107 and 1.8993878755 shares of common stock, respectively (the "IPO
Conversion Ratio"). The IPO Conversion Ratio was not higher than the ratio
which otherwise would have applied in an IPO during this period. In
conjunction with the IPO in January 1996 all outstanding shares of Series A
and Series B preferred stock were converted into 5,521,140 shares of common
stock.

The holders of the Series A and Series B preferred stock received common
stock in January 1996 with an aggregate fair value (at the $5 per unit value
of the IPO) which exceeded by approximately $5,400,000 the cost of their
initial investment in the Series A and Series B preferred stock. This amount
has been deemed to be the equivalent of a preferred stock dividend. The
Company recorded the deemed dividend at the time of conversion by offsetting
charges and credits to additional paid in capital, without any effect on
total stockholders' equity (net capital deficiency). There was no effect on
1995 or 1996 net loss or pro forma net loss per share from the mandatory
conversion. However, the amount increased the loss allocable to common
stock, in the calculation of net loss per share in 1996.

COMMON STOCK

In January 1996, the Company issued 3,200,000 units at $5.00 per unit in
its IPO. Each unit consisted of one share of common stock and one redeemable
Class A warrant. The net proceeds (after underwriter's discount and
expenses, and other costs associated with the IPO) totaled $13,690,357. At
the closing of the offering, all of the Company's then outstanding Series A
and Series B preferred stock automatically converted into common stock. In
February 1996, the Company issued an additional 480,000 units, at $5.00 per
unit, in accordance with the underwriter's over-allotment option. The net
proceeds of the underwriter's over-allotment option totaled $2,160,000.

In July and August 1996, the Company completed a private placement (the
"Private Placement") of 1,536,000 units, each unit consisting of one share of
common stock and one redeemable Class A warrant, for total gross proceeds of
$16,000,000. After deducting placement agent fees and other expenses of the
private placement, the net proceeds to the Company were $13,739,628.

WARRANTS

At December 31, 1997, the Company had a total of 7,507,244 warrants
outstanding to purchase common stock, at a weighted average exercise price of
$6.07. Such warrants expire from November 1998 to January 2001. The
warrants include 7,031,986 Class A warrants issued during 1996 in connection
with the IPO, repayment of a bridge financing and the Private Placement.
They entitle the holder to purchase one share of common stock at an exercise
price of $6.20, subject to adjustment in certain circumstances, at any time
for a period of five years. The warrants are subject to redemption by the
Company at $0.05 per warrant on 30 days' prior written notice if the closing
bid price of the Company's common stock averages in excess of $9.10 per share
for 30 consecutive trading days ending within 15 days of the date of notice
of redemption. The Company has reserved a sufficient number of authorized
but unissued shares of common stock for issuance upon exercise of the
warrants.

UNIT PURCHASE OPTIONS

In connection with the IPO, the underwriter was granted an option ("Unit
Purchase Option") to acquire 320,000 additional units at a price of $6.20 per
unit, and in connection with the private, the placement agent was granted a
Unit Purchase Option to purchase an additional 307,200 units at a price of
$10.42 per unit. Each unit consists of one share of common stock and one
Class A warrant.

8. STOCK OPTION PLANS

Under the terms of the Company's amended and restated stock option plan
(the "1993 Option Plan"), incentive stock options may be granted to
employees, and nonstatutory stock options may be granted to employees,
directors and consultants of the Company and Operating Companies. A total of
558,073 shares of common stock have been reserved and authorized for issuance
under the 1993 Option Plan.

Options granted under the 1993 Option Plan expire no later than ten years
from the date of grant, except when the grantee is a 10% shareholder of the
Company or an Operating Company, in which case the maximum term is five years
from the date of grant. The exercise price of incentive stock options,
nonstatutory stock options and options granted to 10% shareholders of the
Company (or the Operating Companies), shall be at least 100%, 85% and 110%,
respectively, of the fair market value of the stock subject to the option on
the grant date. The options are exercisable immediately upon grant, however,
the shares issuable upon exercise of the options are subject to repurchase by
the Company. Such repurchase rights will lapse over a period of up to five
years from the date of grant. At December 31, 1997, 114,194 shares of common
stock underlying the options would be subject to repurchase by the Company
should such options be exercised and the optionees' employment or consulting
relationship terminate. No further options will be granted under the 1993
Option Plan.

In November 1995, the Company adopted the 1995 Stock Option Plan (the
"1995 Option Plan"). A total of 1,300,000 shares of common stock are
reserved and authorized for issuance under the 1995 Option Plan. Options
granted under the 1995 Option Plan expire no later than ten years from the
date of grant, except when the grantee is a 10% shareholder of the Company or
an Operating Company, in which case the maximum term is five years from the
date of grant. The exercise price of incentive stock options, nonstatutory
stock options and options granted to 10% shareholders of the Company (or the
Operating Companies), shall be at least 100%, 85% and 110%, respectively, of
the fair market value of the stock subject to the option on the grant date.
The provisions of the 1995 Option Plan provide for the automatic grant of
nonqualified stock options to purchase shares of common stock to directors of
the Company who are not principal (10%) stockholders of the Company
("Eligible Directors"). Each Eligible Director of the Company was granted an
option to purchase 10,000 shares of common stock upon the effective date of
the IPO. Future Eligible Directors will be granted a Director Option to
purchase 10,000 shares of Common

F-19

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Stock on the date that such person is first elected or appointed a director.
Each Eligible Director will receive an automatic grant of a Director Option
to purchase 2,000 shares of Common Stock on the day immediately following the
date of each annual meeting of stockholders, as long as such director is a
member of the Board of Directors.

The increase in the shares reserved during 1997 was due to options issued
in conjunction with the liquidation of Trilex. The 1995 Option Plan allows
that stock options issued as the result of a merger or consolidation
("Substitute Options") will be added to the maximum number of shares provided
for in the plan. Consequently, Substitute Options are not returned to the
shares reserved under the plan when cancelled. During 1997, 123,576
Substitute Options were cancelled and are included as shares expired during
the year.

Of the options on 1,402,306 shares outstanding at December 31, 1996,
options on 262,344 shares were exercisable at that date. The options
outstanding at December 31, 1997 have been segregated into three ranges for
additional disclosure as follows:

Operating Companies have been and may be granted.

STOCK COMPENSATION

The Company has elected to follow APB 25 and related interpretations in
accounting for its stock options because, as discussed below, the alternative
fair value accounting provided for under SFAS 123 requires use of option
valuation models that were not developed for use in valuing employee stock
options. Under APB 25, because the exercise price of the Company's employee
stock options equals the market price of the underlying stock on the date of
the grant, no compensation expense is recognized.

Pro forma information regarding the net income and earnings per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its employee stock options granted subsequent to 1994 under the fair
value method of that Statement. The fair value for these options was
estimated at the date of grant using a Black-Scholes option pricing model for
the multiple option approach with the following assumptions for 1997, 1996
and 1995: weighted-average volatility factor of 0.7, 0.6, and 0.6,
respectively; no expected dividend payments; weighted-average risk-free
interest rates in effect of 5.5, 6.38, and 6.00, respectively; and a
weighted-average expected life of 3.79, 4.77, and 4.41, respectively.

The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting
restrictions and are fully transferable. In addition, option valuation
models require the input of highly subjective assumptions including the
expected stock price volatility. Because 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 the Company's employee stock options.

Based upon the above methodology, the weighted-average fair value of
options granted during the years ended December 31, 1997, 1996 and 1995 was
$1.90, $5.71and $0.73, respectively.

For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to pro forma net loss over the options' vesting period.
The Company's pro forma information is as follows:



DECEMBER 31,
----------------------------------------------
1997 1996 1995
------------ ------------- -------------

Consolidated pro forma net loss attributable
to common stockholders . . . . . . . . . . $ (2,065,259) $ (20,233,716) $ (11,852,518)

Consolidated pro forma net loss per share . . . $ (0.16) $ (1.85) $ (1.76)




The consolidated pro forma net loss calculated above includes the
estimated fair value of the options granted by each of the operating
companies in 1997 and 1996, calculated on substantially equivalent
assumptions.

Because SFAS 123 is applicable only to options granted subsequent to 1994,
its pro forma effect will not be fully reflected until 1998.

9. MINORITY INTEREST

The $1,241,032 received by Ingenex upon the issuance of Series B
convertible preferred stock has been classified as minority interest in the
consolidated balance sheet and has not been reduced by any portion of the
losses of Ingenex.

Amounts invested by outside investors in the common stock of the
consolidated subsidiaries has been apportioned between minority interest and
additional paid-in capital in the consolidated balance sheets. Losses
applicable to the minority interest holdings of the Operating Companies'
common stock have reduced that interest.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

10. INCOME TAXES

As of December 31, 1997, the Company had federal net operating loss
carryforwards of approximately $31,300,000, of which approximately
$24,500,000 is attributable to the Operating Companies. The net operating
loss carryforwards will expire at various dates beginning in 2008 through
2012, if not utilized.

Utilization of the net operating losses may be subject to a substantial
annual limitation due to the ownership change limitations provided by the
Internal Revenue Code of 1986. The annual limitation may result in the
expiration of net operating losses before utilization.

As of December 31, 1997, the company had deferred tax assets of
approximately $14,500,000, of which approximately $10,200,000 is attributable
to the Operating Companies. The net deferred tax asset has been fully offset
by a valuation allowance. The net valuation allowance increased by
approximately $4,000,000 during 1996.

Significant components of the Company's deferred tax assets for federal
income taxes as of December 31, 1997 and 1996 are as follows:

11. ILOPERIDONE LICENSE AGREEMENTS

In January 1997, the Company entered into an exclusive license agreement
with Hoechst Marion Roussel, Inc. ("HMRI"). The license agreement gave the
Company a worldwide license to HMRI's patent rights and know-how related to
the antipsychotic agent Iloperidone-TM-, including the ability to develop,
use, sublicense, manufacture and sell products and processes claimed in the
patent rights. Pursuant to the license, the Company paid, during 1997, an
up-front license fee of $9,500,000, consisting of: (i) $4,000,000 in cash
and (ii) $5,500,000 through the issuance 594,595 shares of common stock.
The Company is obligated to pay to HMRI the difference between $5.5 million
and the net proceeds, if any, received by HMR upon sale of the above
mentioned common stock. Accordingly, the Company has classified the entire
$5.5 million as a non-current liability under the heading Guaranteed Security
Value in the accompanying balance sheet. Any cash paid under the guarantee
agreement will be charged against this balance, and the remaining balance, if
any, will be transferred to common stock (see Note 12). The Company is
required to make additional benchmark payments as specific milestones are
met. Upon commercialization of the product, the license agreement provides
that the Company will pay royalties based on net sales.

In November 1997, Titan and Novartis Pharma AG ("Novartis") entered into
an agreement (the "Novartis Sublicense") pursuant to which the Company
granted Novartis a sublicense for the worldwide (with the exception of Japan)
development, manufacturing and marketing of Iloperidone. Pursuant to the
Novartis Sublicense, Novartis paid to the Company $20 million consisting of
an up-front license fee of $15 million and $5 million for the purchase of
606,061 shares of Series D convertible preferred stock. In addition,
approximately $2.4 million in cash was paid by Novartis as reimbursement of
research and development costs incurred by the Company. The Novartis
Sublicense provides for future payments by Novartis contingent upon the
achievement of regulatory milestones as well as a royalty on net sales, if
any, of the product. Novartis has assumed the clinical development,
registration and marketing costs of Iloperidone.

12. SUBSEQUENT EVENT ("UNAUDITED")

SALE OF THE HMRI SHARES

In February 1998, HMRI sold the HMRI Shares for net proceeds of
approximately $2,456,000. Accordingly, in March 1998, the Company paid to
HMRI approximately $3,044,000, which will be deducted from Guaranteed
Security Value balance. The remaining balance of $2,456,000 will be
transferred to stockholders' equity.
