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

<PAGE>

  -  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

<PAGE>

     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

<PAGE>

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.

     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

<PAGE>


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

<PAGE>

     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

<PAGE>

     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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

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

<PAGE>

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.

DIRECTOR COMPENSATION

     Non-employee directors are entitled to receive $2,000 for each Board and

are reimbursed for their expenses in attending such meetings.  Directors are 
not precluded from serving the Company in any other capacity and receiving 
compensation therefor.  In addition, directors are entitled to receive 
options ("Director Options") pursuant to the Company's 1995 Stock Option 
Plan.  Director Options are exercisable in four equal annual installments 
commencing six months from the date of grant and expire the earlier of 10 
years after the date of grant or 90 days after the termination of the

BOARD COMMITTEES AND DESIGNATED DIRECTORS

     The Board of Directors has an Executive Committee, a Compensation 
Committee and an Audit Committee.  The Executive Committee exercises all the 
power and authority of the Board of Directors in the management of the 
Company between Board meetings, to the extent permitted by law.  The 
Compensation Committee makes recommendations to the Board concerning salaries 
and incentive compensation for officers and employees of the Company and may 
administer the Company's 1995 Stock Option Plan.  The Audit Committee reviews 
the results and scope of the audit and other accounting related matters.

     The Board of Directors met six times during 1997 and also took action by 
unanimous written consent.  The Executive Committee met two times and also 
took action by unanimous written consent, and the Compensation Committee and 
Audit Committee each met one time.  Each of the current directors of the 
Company attended at least 75% of the aggregate of (i) the meetings of the 
Board of Directors and (ii) meetings of any Committees of the Board on which 
such person served which were held during the time such person served.

     The Company has agreed, if requested by D.H. Blair Investment Banking 
Corp., the underwriter of the IPO ("Blair"), to nominate a designee of Blair 
to the Company's Board of Directors until January 18, 2001.

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

<PAGE>

(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.

                     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.

                           (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

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:

(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.

                           (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.

   Summarized financial information for Ansan is as follows:

if any.  In addition, in order to maintain license and other rights during 
product development, the Company must comply with various conditions 
including the payment of patent related costs and obtaining additional equity 
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

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

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.

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

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

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   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:

</TABLE>

   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.

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.

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.

                                PREFERENCES AND RIGHTS
                                       OF THE 
                         SERIES C CONVERTIBLE PREFERRED STOCK
                             (par value $.001 per share)

                                          of

                            TITAN PHARMACEUTICALS, INC.
                                a Delaware Corporation

                                      __________

                           Pursuant to Section 151 of the 
                   General Corporation Law of the State of Delaware
                                      __________

     The undersigned DOES HEREBY CERTIFY that the following resolution was duly
adopted by the Board of Directors (the "Board of Directors") of Titan
Pharmaceuticals, Inc., a Delaware corporation (the "Corporation"), at a meeting
held on July 29, 1997:

     RESOLVED, that one series of the class of authorized preferred stock, $.001
par value, of the Corporation is hereby created and that the designations,
powers, preferences and relative, participating, optional or other special
rights of the shares of such series, and qualifications, limitations or
restrictions thereof, are hereby fixed as follows (this instrument hereinafter
referred to as the "Designation"):

     1.   NUMBER OF SHARES AND DESIGNATIONS.  222,400 shares of the preferred
stock, $.001 par value, of the Corporation are hereby constituted as a series of
preferred stock of the Corporation designated as Series C Convertible Preferred
Stock (the "Series C Preferred Stock").

     2.   DIVIDEND PROVISIONS.  Subject to the rights of any series of Preferred
Stock that may from time to time come into existence, the holders of share of
Series C Preferred Stock shall be entitled to receive dividends, when, as and if
declared by the Board of Directors, out of any assets legally available
therefor, ratably with any declaration or payment of any dividend (payable other
than solely in Common Stock or other securities and rights convertible into or
entitling the holder thereof to receive, directly or indirectly, additional
shares of Common Stock of this Corporation) on the Common Stock or other junior
securities of this Corporation.

     3.   LIQUIDATION PREFERENCE.

          (a)  Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary ("Liquidation"), the holders of
record of the shares of the Series C Preferred Stock shall be entitled to
receive, before and in preference to any distribution or 

<PAGE>

payment of assets of the Corporation or the proceeds thereof may be made or 
set apart for the holders of Common Stock or any other security junior to the 
Series C Preferred Stock in respect of distributions upon Liquidation out of 
the assets of the Corporation legally available for distribution to its 
stockholders, an amount in cash equal to $.01 per share (subject to 
adjustment in the event of stock splits, combinations or similar events) plus 
an amount equal to all accrued and unpaid dividends, if any, on each share of 
Series C Preferred Stock on the date fixed for the distribution of assets of 
the Corporation (the "Series C Liquidation Preference").  If, upon such 
Liquidation, the assets of the Corporation available for distribution to the 
holders of Series C Preferred Stock and any other series of preferred stock 
then outstanding ranking on parity with the Series C Preferred Stock upon 
liquidation ("Parity Stock") shall be insufficient to permit payment in full 
to the holders of the Series C Preferred Stock and Parity Stock, then the 
entire assets and funds of the Corporation legally available for distribution 
to such holders and the holders of the Parity Stock then outstanding shall be 
distributed ratably among the holders of the Series C Preferred Stock and 
Parity Stock based upon the proportion the total amount distributable on each 
share upon liquidation bears to the aggregate amount available for 
distribution on all shares of the Series C Preferred Stock and of such Parity 
Stock, if any.

          (b)  Upon the completion of the distributions required by subparagraph
(a) of this Paragraph 3 and any other distribution that may be required with
respect to series of preferred stock that may from time to time come into
existence, the holders of Common Stock shall be entitled to receive an aggregate
amount equal to the sum of stated capital plus additional paid-in capital
attributable to the Common Stock, as reflected on the Corporation's audited
consolidated balance sheet as of the end of the fiscal year next preceding the
date of such distribution, which aggregate amount shall be distributed ratably
among the holders of Common Stock in proportion to the number of shares of
Common Stock held by each such holder.  If, upon the occurrence of such event,
the assets and funds thus distributed among the holders of the Common Stock
shall be insufficient to permit the payment to such holders of the full
aforesaid aggregate amount, then the entire remaining assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Common Stock in proportion to the number of shares of
Common Stock held by each such holder.  

          (c)  Upon the completion of the distributions required by subparagraph
(b) of this Paragraph 3, the remaining assets of the Corporation available for
distribution to stockholders shall be distributed among the holders of Series C
Preferred Stock, Parity Stock and the Common Stock PRO RATA based on the number
of shares of Common Stock held by each and issuable upon conversion of all such
Series C Preferred Stock or Parity Stock.

          (d)   For purposes of this Paragraph 3, a merger or consolidation or a
sale of all or substantially all of the assets of the Corporation shall be
considered a Liquidation except (i) in the event that in such a transaction, the
holders of the Series C Preferred Stock receive securities of the surviving
corporation having substantially similar rights as the Series C Preferred Stock
and the stockholders of the Corporation immediately prior to such transaction
are holders of at least a majority of the voting securities of the surviving
corporation immediately thereafter or (ii) in the event of a merger or
consolidation in which the Corporation is not the surviving entity, the

                                        -2-

<PAGE>

Corporation elects to convert the Series C Preferred Stock into an equal number
of shares of Common Stock as set forth in Paragraph 5(b) below.

     4.   OPTIONAL REDEMPTION BY CORPORATION.  In the event that the outstanding
shares of Series C Preferred Stock have not converted into shares of Common
Stock pursuant to Paragraph 5(a) or (b) below or the Corporation has not
received a notice of Conditional Approval (as defined below), then at any time
after September __, 2004 (the "Original Redemption Date"), the Corporation may
redeem all, but not less than all, of the outstanding shares of Series C
Preferred Stock at a redemption price equal to the aggregate par value of such
shares (the "Redemption Price") plus accrued and unpaid dividends, if any.  In
the event that a notification from the United States Food and Drug
Administration (the "FDA") granting a conditional approval (a "Conditional
Approval") of either Cea Vac, TriGem or TriAB (the "Drugs") is received by the
Corporation prior to the Original Redemption Date and the outstanding shares of
Series C Preferred Stock have not converted into shares of Common Stock pursuant
to Paragraph 5(a) or (b) below, the Original Redemption Date shall be extended
until the latest date on which the Corporation has received a withdrawal notice
with respect to each Conditional Approval received prior to the Original
Redemption Date (the "Extended Redemption Date") and, in the event the Original
Redemption Date is extended, the Corporation may redeem all, but not less than
all, of the outstanding shares of Series C Preferred Stock at the Redemption
Price, plus accrued and unpaid dividends, if any, at any time after the Extended
Redemption Date.   .

     5.   CONVERSION. 

          (a)  AUTOMATIC CONVERSION.  Upon receipt of notification (the
"Notification") from the FDA that any of the Drugs are approved for final
marketing and commercialization by the Corporation (the "Conversion Event"),
PROVIDED that the Conversion Event occurs prior to the (i) Original Redemption
Date or (ii) the Extended Redemption Date in the event a Conditional Approval
exists at the time of the Notification, each share of Series C Preferred Stock
then outstanding shall, by virtue of and immediately prior to the Conversion
Event and without any action on the part of the holder thereof (except as set
forth in Paragraph 5(c) below), be deemed automatically converted into that
number of shares of Common Stock into which the Series C Preferred Stock would
then be converted at the then effective Conversion Rate (as defined below). 
Each share of Series C Preferred Stock shall be convertable into one share of
Common Stock (the "Conversion Rate"), subject to adjustment as set forth in
Paragraph 5(d).

          (b)  OPTIONAL CONVERSION BY CORPORATION.  At any time the share of
Series C Preferred Stock are outstanding, the Corporation shall have the right
to elect to convert any or all of the shares of Series C Preferred Stock
outstanding immediately prior to such conversion, and upon such election by the
Corporation, and without any action on the part of the holder thereof (except as
set forth in Paragraph 5(c) below), each share of Series C Preferred Stock then
outstanding shall be deemed automatically converted into that number of shares
of Common Stock into which the Series C Preferred Stock would then be converted
at the then effective Conversion Rate.

                                        -3-

<PAGE>

          (c)  MECHANICS OF CONVERSION.  In the event that the Series C
Preferred Stock is converted into shares of Common Stock pursuant to Paragraph
(a) or (b) above, the holder of the Series C Preferred Stock shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series C Preferred Stock, and shall
give written notice to the Corporation at its principal corporate office, which
notice shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued.  The Corporation
shall, as soon as practicable thereafter, issue and deliver to such holder of
Series C Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid.  Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series C Preferred Stock to be converted, and the
person or persons entitled to receive the shares of Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock as of such date.  

          (d)  CONVERSION RATE ADJUSTMENTS.  The Conversion Rate of the Series C
Preferred Stock shall be subject to adjustment from time to time as set forth
below.

               (i)  In case the Corporation shall (a) issue Common Stock as a
dividend or distribution on any class of the capital stock of the Company,
(b) split or otherwise subdivide its outstanding Common Stock, (c) combine the
outstanding Common Stock into a smaller number of shares, or (d) issue by
reclassification of its Common Stock (except in the case of a merger,
consolidation or sale of all or substantially all of the assets of the Company
as set forth in subparagraph 5(d)(ii) below) the Conversion Rate in effect on
the record date for any stock dividend or the effective date of any such other
event shall be adjusted so that the holder of each share of the Series C
Preferred Stock shall thereafter be entitled to receive, upon the conversion of
such share, the number of shares of Common Stock or other capital stock which it
would own or be entitled to receive immediately after the happening of any of
the events mentioned above had such share of the Series C Preferred Stock been
converted immediately prior to the close of business on such record date or
effective date.  The adjustments herein provided shall become effective
immediately following the record date for any such stock dividend or the
effective date of any such other events.  There shall be no adjustment in the
Conversion Rate in the event that the Company pays a cash dividend.

               (ii) In case of any reclassification or similar change of
outstanding shares of Common Stock of the Company, or in case of the
consolidation or merger of the Company with another corporation, subject to
subparagraph 5(b), or the conveyance of all or substantially all of the assets
of the Company in a transaction in which holders of the Common Stock receive
shares of stock or other property including cash, each share of the Series C
Preferred Stock shall, after such event and subject to the other rights of the
Series C Preferred Stock as set forth elsewhere herein, be convertible only into
the number of shares of stock or other securities or property, including cash,
to which a holder of the number of shares of Common Stock of the Company
deliverable upon conversion of such shares of the Series C Preferred Stock 

                                        -4-

<PAGE>

would have been entitled upon such reclassification, change, consolidation, 
merger or conveyance had such share been converted immediately prior to the 
effective date of such event.

          (e)  The Company shall at all times reserve and keep available, out of
its authorized but unissued shares of Common Stock or out of shares of Common
Stock held in its treasury, solely for the purpose of effecting the conversion
of the shares of the Series C Preferred Stock, the full number of shares of
Common Stock deliverable upon the conversion of all shares of the Series C
Preferred Stock from time to time outstanding.  The Company shall from time to
time in accordance with Delaware law take all steps necessary to increase the
authorized amount of its Common Stock if at any time the authorized number of
shares of Common Stock remaining unissued shall not be sufficient to permit the
conversion of all of the shares of the Series C Preferred Stock.

          (f)  (i)  No fractional shares or scrip representing fractional shares
of Common Stock shall be issued upon the conversion of the Series C Preferred
Stock.  In lieu of any fractional shares to which a holder would otherwise be
entitled, the Company shall pay cash, equal to such fraction multiplied by the
closing price (determined as provided in subparagraph (ii) of this Paragraph
5(f)) of the Common Stock on the day of conversion.

               (ii) For the purposes of any computation under subparagraph
5(f)(i), the current market price per share of Common Stock on any date shall be
deemed to be the average of the daily closing prices for the 20 consecutive
business days prior to the day in question.  The closing price for each day
shall be the last sales price regular way or in case no sale takes place on such
day, the average of the closing high bid and low asked prices regular way, in
either case (a) as officially quoted by the Nasdaq SmallCap Market or the Nasdaq
National Market or such other market on which the Common Stock is then listed
for trading, or (b) if, in the reasonable judgment of the Board of Directors of
the Company, the Nasdaq SmallCap Market or the Nasdaq National Market is no
longer the principal United States market for the Common Stock, then as quoted
on the principal United States market for the Common Stock, as determined by the
Board of Directors of the Company, or (c) if, in the reasonable judgment of the
Board of Directors of the Company, there exists no principal United States
market for the Common Stock, then as reasonably determined by the Board of
Directors of the Company. 

          (g)  The Company will not, by amendment of its Certificate of
Incorporation, as amended, or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the provisions of this Paragraph 5 and in the taking of all such action as may
be necessary or appropriate in order to protect the conversion rights of the
holders of the Series C Preferred Stock against impairment.

     6.   VOTING RIGHTS.  

                                        -5-

<PAGE>

          (a)  Except as otherwise specifically provided herein or by applicable
law, the Series C Preferred Stock shall have no right to vote with respect to
any question upon which holders of the Corporation's capital stock have the
right to vote.  

          (b)  So long as any shares of the Series C Preferred Stock remain
outstanding, the consent of two-thirds of the holders of the then outstanding
Series C Preferred Stock, voting as one class, either expressed in writing or at
a meeting called for that purpose, shall be necessary to repeal, amend or
otherwise change this Designation or the Certificate of Incorporation of the
Company, as amended, in a manner which would alter or change the powers,
preferences, rights privileges, restrictions and conditions of the Series C
Preferred Stock so as to adversely affect the Series C Preferred Stock.  The
Series C Preferred Stock shall have no right to vote with respect to the
authorization and/or issuance by the Company of any new series of preferred

with, or senior to those of the Series C Preferred Stock.

          (c)  Each share of the Series C Preferred Stock shall entitle the
holder thereof to one vote on all matters to be voted on by the holders of the
Series C Preferred Stock, as set forth above.

     7.   STATUS OF REDEEMED OR CONVERTED STOCK.  In the event any shares of
Series C Preferred Stock shall be redeemed or converted pursuant to Paragraph 4
or 5 hereof, the shares so redeemed or converted shall be cancelled and shall
not be issuable by the Corporation.  The Certificate of Incorporation of the
Corporation, as amended, may be appropriately amended from time to time to
effect the corresponding reduction in the Corporation's authorized capital
stock.

     8.   TRANSFERABILITY.  The holders of the Series C Preferred Stock shall
not sell, assign or otherwise transfer any shares of Series C Preferred Stock
without the written consent of the Corporation.

                                PREFERENCES AND RIGHTS
                                       OF THE 
                         SERIES D CONVERTIBLE PREFERRED STOCK
                             (par value $.001 per share)

                                          of

                            TITAN PHARMACEUTICALS, INC.
                                a Delaware Corporation

                                      __________

                           Pursuant to Section 151 of the 
                   General Corporation Law of the State of Delaware
                                      __________

     The undersigned DOES HEREBY CERTIFY that the following resolution was duly
adopted by the Board of Directors (the "Board of Directors") of Titan
Pharmaceuticals, Inc., a Delaware corporation (the "Corporation"), at a meeting
held on November 3, 1997:

     RESOLVED, that one series of the class of authorized preferred stock, $.001
par value, of the Corporation is hereby created and that the designations,
powers, preferences and relative, participating, optional or other special
rights of the shares of such series, and qualifications, limitations or
restrictions thereof, are hereby fixed as follows (this instrument hereinafter
referred to as the "Designation"):

     1.   NUMBER OF SHARES AND DESIGNATIONS.  606,061 shares of the preferred
stock, $.001 par value, of the Corporation are hereby constituted as a series of
preferred stock of the Corporation designated as Series D Convertible Preferred
Stock (the "Series D Preferred Stock").

     2.   DIVIDEND PROVISIONS.  Subject to the rights of any series of Preferred
Stock that may from time to time come into existence, the holders of share of
Series D Preferred Stock shall be entitled to receive dividends, when, as and if
declared by the Board of Directors, out of any assets legally available
therefor, ratably with any declaration or payment of any dividend (payable other
than solely in Common Stock or other securities and rights convertible into or
entitling the holder thereof to receive, directly or indirectly, additional
shares of Common Stock of this Corporation) on the Common Stock or other junior
securities of this Corporation.

     3.   LIQUIDATION PREFERENCE.

          (a)  Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary ("Liquidation"), the holders of
record of the shares of the Series D Preferred Stock shall be entitled to
receive, before and in preference to any distribution or 


<PAGE>

payment of assets of the Corporation or the proceeds thereof may be made or 
set apart for the holders of Common Stock or any other security junior to the 
Series D Preferred Stock in respect of distributions upon Liquidation out of 
the assets of the Corporation legally available for distribution to its 
stockholders, an amount in cash equal to $.05 per share (subject to 
adjustment in the event of stock splits, combinations or similar events) plus 
an amount equal to all accrued and unpaid dividends, if any, on each share of 
Series D Preferred Stock on the date fixed for the distribution of assets of 
the Corporation (the "Series D Liquidation Preference").  If, upon such 
Liquidation, the assets of the Corporation available for distribution to the 
holders of Series D Preferred Stock and any other series of preferred stock 
then outstanding ranking on parity with the Series D Preferred Stock upon 
liquidation ("Parity Stock") shall be insufficient to permit payment in full 
to the holders of the Series D Preferred Stock and Parity Stock, then the 
entire assets and funds of the Corporation legally available for distribution 
to such holders and the holders of the Parity Stock then outstanding shall be 
distributed ratably among the holders of the Series D Preferred Stock and 
Parity Stock based upon the proportion the total amount distributable on each 
share upon liquidation bears to the aggregate amount available for 
distribution on all shares of the Series D Preferred Stock and of such Parity 
Stock, if any.

          (b)  Upon the completion of the distributions required by subparagraph
(a) of this Paragraph 3 and any other distribution that may be required with
respect to series of preferred stock that may from time to time come into
existence, the holders of Common Stock shall be entitled to receive an aggregate
amount equal to the sum of stated capital plus additional paid-in capital
attributable to the Common Stock, as reflected on the Corporation's audited
consolidated balance sheet as of the end of the fiscal year next preceding the
date of such distribution, which aggregate amount shall be distributed ratably
among the holders of Common Stock in proportion to the number of shares of
Common Stock held by each such holder.  If, upon the occurrence of such event,
the assets and funds thus distributed among the holders of the Common Stock
shall be insufficient to permit the payment to such holders of the full
aforesaid aggregate amount, then the entire remaining assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Common Stock in proportion to the number of shares of
Common Stock held by each such holder.  

          (c)  Upon the completion of the distributions required by subparagraph
(b) of this Paragraph 3, the remaining assets of the Corporation available for
distribution to stockholders shall be distributed among the holders of Series D
Preferred Stock, Parity Stock and the Common Stock PRO RATA based on the number
of shares of Common Stock held by each and issuable upon conversion of all such
Series D Preferred Stock or Parity Stock.

     4.   REDEMPTION.  The Series D Preferred Stock is not redeemable.

     5.   CONVERSION. 

          (a)  OPTIONAL CONVERSION. The holder shall have the right, at any time
after January 29, 1999, to convert any or all of the shares of Series D
Preferred Stock outstanding immediately prior to such conversion into that
number of shares of Common Stock equal to the 

                                        -2-

<PAGE>

multiple of the following two fractions: (a) the number of shares of Series D 
Preferred Stock to be converted divided by 606,061 and (b) 5,000,000 divided 
by the conversion price in effect at the time of conversion (the "Conversion 
Price").  The Conversion Price shall mean the average of the closing prices 
for the Corporation's Common Stock for any 20 consecutive trading days during 
the period from January 1, 1999 through June 30, 1999 (the "Market Price") 
chosen by Novartis Pharma AG ("Novartis"); provided, however,  if the Market 
Price is greater than $9.00 (the "Ceiling"), the Conversion Price will be 
$9.00 and if the Market Price is less than $7.50 (the "Floor"), the 
Conversion Price will be $7.50.  The closing price for each day shall be the 
last sales price of the day or in case no sale takes place on such day, the 
average of the closing high bid and low asked prices, in either case (a) as 
officially quoted by the Nasdaq SmallCap Market or the Nasdaq National Market 
or such other market on which the Common Stock is then listed for trading, or 
(b) if, in the reasonable judgment of the Board of Directors of the 
Corporation, the Nasdaq SmallCap Market or the Nasdaq National Market is no 
longer the principal United States market for the Common Stock, then as 
quoted on the principal United States market for the Common Stock, as 
determined by the Board of Directors of the Corporation, or (c) if, in the 
reasonable judgment of the Board of Directors of the Corporation, there 
exists no principal United States market for the Common Stock, then as 
reasonably determined by the Board of Directors of the Corporation. The 
number of shares of Common Stock into which each share of Series D Preferred 
Stock is convertible is hereinafter collectively referred to as the 
"Conversion Rate." The Conversion Rate is subject to adjustment pursuant to 
the provisions of Paragraph 5(d) below.

          (b)  AUTOMATIC CONVERSION.  If at any time the Corporation effects a
merger, consolidation or sale of substantially all of its assets (a "Conversion
Event"), each share of Series D Preferred Stock then outstanding shall, by
virtue of and immediately prior to the Conversion Event and without any action
on the part of the holder thereof (except as set forth in Paragraph 5(c) below),
be deemed automatically converted into that number of shares of Common Stock
into which the Series D Preferred Stock would then be converted at either (i)
the Market Price as of the date of the first public announcement of the
Conversion Event (subject to the Floor and Ceiling set forth in Paragraph 5(a)
above) in the event the Conversion Event occurs prior to the earlier of June 30,
1999 or establishment by Novartis of the Conversion Price or (ii) the Conversion
Price.

          (c)  MECHANICS OF CONVERSION.  In the event that the Series D
Preferred Stock is converted into shares of Common Stock pursuant to Paragraphs
5(a) or 5(b) above, the holder of the Series D Preferred Stock shall surrender
the certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series D Preferred Stock, and shall
give written notice to the Corporation at its principal corporate office, which
notice shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued.  The Corporation
shall, as soon as practicable thereafter, issue and deliver to such holder of
Series C Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid.  Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series D Preferred Stock to be converted, 

                                        -3-

<PAGE>

and the person or persons entitled to receive the shares of Common Stock 
issuable upon such conversion shall be treated for all purposes as the record 
holder or holders of such shares of Common Stock as of such date.  

          (d)  CONVERSION RATE ADJUSTMENTS.  The Conversion Rate shall be
adjusted in case the Corporation shall, at any time prior to conversion of the
Series D Preferred Stock pursuant to Paragraphs 5(a) or 5(b) above, (a) issue
Common Stock as a dividend or distribution on any class of the capital stock of
the Corporation, (b) split or otherwise subdivide its outstanding Common Stock,
(c) combine the outstanding Common Stock into a smaller number of shares, or
(d) issue securities by reclassification of its Common Stock (except in the case
of a merger, consolidation or sale of all or substantially all of the assets of
the Corporation) so that the holder of each share of the Series D Preferred
Stock shall thereafter be entitled to receive, upon the conversion of such
share, the number of shares of Common Stock or other capital stock which it
would own or be entitled to receive immediately after the happening of any of
the events mentioned above had such share of the Series D Preferred Stock been
converted immediately prior to the close of business on such record date or
effective date.  There shall be no adjustment in the Conversion Rate in the
event that the Corporation pays a cash dividend.

          (e)  The Corporation shall at all times reserve and keep available,
out of its authorized but unissued shares of Common Stock or out of shares of
Common Stock held in its treasury, solely for the purpose of effecting the
conversion of the shares of the Series D Preferred Stock, the full number of
shares of Common Stock deliverable upon the conversion of all shares of the
Series D Preferred Stock from time to time outstanding.  The Corporation shall
from time to time in accordance with Delaware law take all steps necessary to
increase the authorized amount of its Common Stock if at any time the authorized
number of shares of Common Stock remaining unissued shall not be sufficient to
permit the conversion of all of the shares of the Series D Preferred Stock.

          (f)  No fractional shares or scrip representing fractional shares of
Common Stock shall be issued upon the conversion of the Series D Preferred
Stock.  In lieu of any fractional shares to which a holder would otherwise be
entitled, the Corporation shall pay cash, equal to such fraction multiplied by
the Market Price of the Common Stock on the day of conversion.

          (g)  The Corporation will not, by amendment of its Certificate of
Incorporation, as amended, or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Paragraph 5 and in the taking of all such action as
may be necessary or appropriate in order to protect the conversion rights of the
holders of the Series D Preferred Stock against impairment.

     6.   VOTING RIGHTS.  

                                        -4-

<PAGE>

          (a)  In addition to any other rights provided for herein or by law,
the holders of Series D Preferred Stock shall be entitled to vote, together with
the holders of Common Stock as one class, on all matters as to which holders of
Common Stock shall be entitled to vote, in the same manner and with the same
effect as such Common Stock holders.  In any such vote each share of Series D
Preferred Stock shall entitle the holder thereof to one vote per share.

          (b)  So long as any shares of the Series D Preferred Stock remain
outstanding, the consent of two-thirds of the holders of the then outstanding
Series D Preferred Stock, voting as one class, either expressed in writing or at
a meeting called for that purpose, shall be necessary to repeal, amend or
otherwise change this Designation or the Certificate of Incorporation of the
Corporation, as amended, in a manner which would alter or change the powers,
preferences, rights privileges, restrictions and conditions of the Series D
Preferred Stock so as to adversely affect the Series D Preferred Stock.  The
Series D Preferred Stock shall have no right to vote with respect to the
authorization and/or issuance by the Corporation of any new series of preferred
stock whether or not the terms of such preferred stock are junior to, on parity
with, or senior to those of the Series D Preferred Stock.

          (c)  Each share of the Series D Preferred Stock shall entitle the
holder thereof to one vote on all matters to be voted on by the holders of the
Series D Preferred Stock, as set forth above.

     7.   STATUS OF  CONVERTED STOCK.  In the event any shares of Series D
Preferred Stock shall be redeemed or converted pursuant to Paragraph 5 hereof,
the shares so converted shall be cancelled and shall not be issuable by the
Corporation.  The Certificate of Incorporation of the Corporation, as amended,
may be appropriately amended from time to time to effect the corresponding
reduction in the Corporation's authorized capital stock.

     8.   MISCELLANEOUS.

          (a)  There is no sinking fund with respect to the Series D Preferred
Stock.

          (b)  The shares of the Series D Preferred Stock shall not have any
preferences, voting powers or relative, participating, optional, preemptive or
other special rights except as set forth above in this Designation and in the
Certificate of Incorporation of the Corporation, as amended.

                                        -5-

<PAGE>

     9.   RIGHT TO ELECT DIRECTORS.  

     During the period that the Series D Preferred Stock is outstanding and in
the event of a Default, the holders of Series D Preferred Stock shall
immediately have the right to elect two members of the Corporation's Board of
Directors.  "Default" shall be defined to mean the failure of the Corporation to
pay any dividend on the Series D Preferred Stock declared by the Board of
Directors when due, which failure shall continue for a period of two years.

     IN WITNESS WHEREOF, Titan Pharmaceuticals, Inc. has caused this Designation
to be executed this 17th day of November, 1997.
