ITEM 1.   DESCRIPTION OF BUSINESS.

GENERAL

Ansan Pharmaceuticals, Inc. ("Ansan" or the "Company") is a development 
stage, biopharmaceutical company engaged in the acquisition and further 
development of drugs intended to treat cancer, blood disorders and other 
serious diseases.  The Company attempts to in-license product candidates that 
are past the initial discovery stage.  Such products have already undergone 
preliminary toxicity testing and have demonstrated some level of biological 
activity in animal experiments. The Company believes that acquiring products 
that meet such requirements may allow it to reduce product development time 
frames, reduce the research rejection rate due to safety and toxicity 
concerns, and achieve a higher probability of ultimate commercialization.

The Company was incorporated in Delaware in November 1992 and has been funded 
through private placements of its securities, as well as an initial public 
offering of its securities (the "IPO") in August and September 1995.

The Company will require substantial additional funds in order to conduct the 
several phases of clinical testing in human subjects necessary to complete 
development and to commercialize any of its present or future products.  
There can be no assurance that additional funding will be available to the 
Company on acceptable terms, if at all.  The Company's strategy may be to 
seek joint venture, licensing or other collaborative arrangements with one or 
more pharmaceutical companies which will bear certain costs of further 
development and the regulatory approval process necessary to commercialize 
therapeutics in the United States and in foreign markets.  It is not 
anticipated that any of the Company's current product candidates will receive 
the requisite regulatory approval for commercialization in the United States 
for several years, if at all.

The statements in this report which are not historical facts are 
forward-looking statements that involve risks and uncertainties, including, but 
not limited to, the results of research and development efforts, the results of 
preclinical and clinical testing, the effect of regulation by the United States 
Food and Drug Administration ("FDA") and other agencies, the impact of 
competitive products, product development, commercialization and technological 
difficulties, the results of financing efforts, the effect of the Company's 
accounting policies, and other risks detailed in the Company's Securities and 
Exchange Commission filings.

PRODUCTS AND APPLICATIONS UNDER DEVELOPMENT

The Company's initial product candidates are novel synthetic analogs of 
butyric acid, a molecule occurring naturally in certain foods.  The Company 
believes that these drugs may ultimately prove to be useful in the areas of 
oncology and hematology, and for the treatment of diseases and disorders 
characterized by abnormal cellular proliferation.  Also, in May 1996, the 
Company signed a licensing agreement with Boehringer Ingelheim GmbH  to 
acquire the rights in the United States and the European Union to develop a 
new intravenous formulation of the drug apafant for all clinical indications. 
The Company believes that apafant may ultimately prove to be useful in the 
treatment of acute pancreatitis.

AN9

Chemotherapy, a major component of cancer treatment today, is increasingly 
used as an adjunct to other cancer therapies, such as radiation and surgery, 
to improve the efficacy of treatment.  In addition, chemotherapy is usually 
the primary treatment against metastases, solid tumors, and cancers such as 
hematologic malignancies, which cannot be excised by surgery.  Traditional 
chemotherapeutic agents are cytotoxic, that is, they function by killing 
actively dividing cells.  Traditional cytotoxic chemotherapeutics, therefore, 
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 intestinal lining, which may lead to side effects such as anemia, 
nausea, vomiting and risk of infection.

Cells change as they mature and differentiate, that is, reach their final 
shape, size and function.  Cancer cells, however, often tend to be relatively 
immature or undifferentiated, which may lead to unregulated growth.  Unlike 
traditional cytotoxic chemotherapy, "differentiation therapy" represents a 
relatively new direction in cancer research.  It 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. 


                                      2

<PAGE>

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, it is believed, sparing normal cells (whether or not they are 
rapidly dividing).  Many members of the oncology community believe apoptosis 
to be a highly promising approach to cancer therapy, although it has yet to 
be confirmed as a therapeutic approach applicable across a broad range of 
tumor types.  Consequently, there has been a concentrated effort to find 
"apoptotic drugs."

The Company believes AN9 may be such a drug.  The Company also believes that 
apoptotic agents will reduce the debilitating side effects associated with 
traditional cancer therapies, including bone marrow depression, 
gastrointestinal effects, mucositis and alopecia (hair loss), and thus permit 
more extensive treatment.  However, there can be no guarantee that any 
putative apoptotic agent will ultimately prove to be as broadly efficacious 
across different types of tumors as cytotoxic agents have proven to be in the 
past.

Preliminary experiments have suggested that the natural substance butyric 
acid might be a potential therapy with effects on differentiation and, 
potentially, apoptosis.  IN VITRO testing has demonstrated butyric acid to be 
an effective anticancer agent, as reflected in differentiation of tumor cells 
and growth arrest, against a variety of human tumor cells, but, historically, 
its clinical utility has been hampered by rapid clearance and metabolism in 
tissue cell cultures, resulting in relatively low potency IN VIVO.  In an 
effort to overcome the disadvantages associated with butyric acid, the 
Company's founding scientists undertook research designed to identify novel 
analogs of butyric acid which would show both better IN VIVO potency and 
possibly less rapid metabolic clearance than butyric acid itself.  This 
effort led to the development of the Company's first novel analog of butyric 
acid, AN9, which in laboratory studies has exhibited significant IN VITRO 
potency and which also has useful pharmacokinetic properties such as rapid 
tissue uptake and uniform tissue distribution (including the ability to cross 
the blood brain barrier).  Moreover, AN9 has also been shown to modulate the 
expression of the "cancer genes," C-MYC and C-JUN and to activate the 
expression of the putative tumor suppressor genes, RB and P53.

AN9 appears to demonstrate broad anticancer activity IN VITRO and to promote 
cellular differentiation, suggesting that AN9 may also lead to the cessation 
of growth and then apoptosis in cancer cells.  The Company has also tested 
AN9 IN VITRO against a broad range of human cancer types and has documented 
its activity against numerous tumor cell lines, including, among others, 
leukemia, lung and colon carcinoma, melanoma, pancreatic carcinoma, breast 
and ovarian carcinoma.  AN9 has also demonstrated anticancer activity in 
preclinical studies completed by Clinical Trials Research Center, an 
organization headed by Dr. Daniel Von Hoff.  Dr. Von Hoff, who has advised 
the Company in scientific matters, evaluated AN9 for its anticancer activity 
against a number of clinical specimens collected from patients with solid 
tumors, including breast cancer, ovarian cancer and melanoma resistant to 
existing cytotoxic agents.  These studies indicated that AN9 was more 
effective at inhibiting tumor cell growth in a substantially larger 
percentage of these specimens than were several currently marketed cytotoxic 
agents.  While not active in all IN VIVO experimental settings,  the efficacy 
of AN9 has also been demonstrated in animal models of lung cancer, melanoma 
and moncytic leukemia.

Because of their toxicity, traditional anticancer chemotherapeutic agents 
often must be given in cycles with prolonged "rest periods" between doses. 
This toxicity is often a limiting factor that prevents successful eradication 
of cancer cells.  The Company believes that the potential for lower toxicity 
of AN9 may permit its administration for extended periods, thus potentially 
allowing a more successful eradication of cancer cells and prevention of 
recurrence.

PIVANEX-TM- INJECTION

Pivanex-TM- Injection ("Pivanex"), is an injectable formulation of AN9. While 
butyric acid has been shown to be an effective anticancer agent IN VITRO, 
clinical testing of butyric acid has been hindered by its low potency, rapid 
metabolic clearance and the suspected inability to achieve therapeutic levels 
in target tissues.  The Company believes that Pivanex may have 
characteristics that overcome certain of these problems. Preclinical studies 
of Pivanex have demonstrated a reduction in metastatic spread of cancer 
cells, without unacceptable IN VIVO toxicity in animal studies.  Furthermore, 
IN VITRO studies have shown anticancer activity of Pivanex against a broad 
range of animal cancer cell lines (lung, skin, white blood cell) and against 
certain human cancer cell lines (breast, ovarian, lung, colon and pancreatic 
cancers and melanoma). Positive results have been observed in certain IN VIVO 
animal studies as well although not in all models.  Taken together, the data 
suggest that Pivanex development efforts could potentially result in an 
effective anticancer therapeutic agent with low toxicity.  Clinical testing 
of Pivanex in cancer


                                      3

<PAGE>

patients began in November 1995 pursuant to an Investigational New Drug 
Application ("IND") approved by the United States Food and Drug 
Administration ("FDA").

Animal data generated in parallel with the current clinical study of Pivanex 
have suggested that when Pivanex is administered by vein the highest 
concentrations of drug may be available to treat tumors that are located in 
the lungs.  Substantially less drug is available after intravenous 
administration to treat tumors located outside of the lung.  As a consequence 
of these findings, an effort has been made to enroll patients with lung 
cancer in the current clinical study.  The Company performed an interim 
analysis of the current Pivanex clinical study in November 1996. Nine 
patients had been enrolled and no serious adverse events had been reported. 
Of the nine patients three had lung cancer.  The other six patients enrolled 
previously had cancers located in sites other than the lungs (such as the 
colon or liver), and there was no objective evidence of response to treatment 
in these six patients.

Of the three patients with lung cancer, one had squamous cell carcinoma. This 
patient was enrolled in August 1996, and subsequently received two courses of 
therapy with Pivanex.  Following the first course, there was approximately a 
50% reduction in the tumor volume, as measured by an x-ray technique known as 
computerized tomography.  A repeat x-ray after the second course showed no 
further decrease in tumor size.

The Company and the principal investigator of the clinical trial find this 
reported result encouraging.  There can be no assurance, however, that the 
observed shrinkage of the tumor resulted from the administration of Pivanex, 
can be maintained for any meaningful duration or can be reproduced in other 
patients.  Substantial additional clinical testing will be required to 
establish and verify the safety and efficacy of Pivanex.  These trials will 
require at least two or more years to complete, and there can be no assurance 
that such trials will result in the regulatory approval required for the 
commercialization of Pivanex.

Because of the animal findings regarding the availability of drug to treat 
tumors located in various tissues, the company is currently evaluating 
additional routes of administration for Pivanex, including:

    1.  intraperitoneal administration for treatment of malignancies such as 
        ovarian cancer (The Company has recently shown in laboratory testing 
        that a solution of AN9 given by intraperitoneal administration 
        improves the survival of  animals having human ovarian cancers 
        implanted in the peritoneal cavity.)

    2.  intra-arterial infusions for the treatment of primary or metastatic
        livers cancers

AN9 TOPICAL

It has been previously shown in laboratory testing that direct application of a
solution of AN9 to human melanoma cells can inhibit growth of this type of
cancer.  Pursuant to this observation, the Company has been performing certain
experiments to enable the filing of an IND for a newly developed topical
formulation of AN9 ("AN9 Topical").  The Company has met with the FDA regarding
such an effort.  As a result, the Company may decide to file an IND to proceed
with clinical testing of AN9 Topical in the future.  However, the Company must
complete certain additional toxicology studies before an IND can be submitted,
and there can be no assurance that these studies can be concluded successfully
or in a timely manner.  Accordingly, there can be no assurance that the IND will
be filed in a timely manner or at all and no assurance that the FDA will
ultimately approve the IND if one is filed.

AN10

NOVAHEME-TM- INJECTION

Novaheme Injection ("Novaheme") is an intravenous formulation of AN10, 
another novel analog of butyric acid, that the Company is developing for the 
treatment of -Beta--hemoglobinopathies. These are genetic disorders that 
impair one's ability to produce adult hemoglobin ("HbA"), the oxygen-carrying 
protein of red blood cells.  The most common of the -Beta--hemoglobinopathies 
are -Beta--thalassemia and sickle-cell anemia.  In normal 
adults, HbA comprises more than 99% of hemoglobin.  Patients suffering from 
- -Beta--thalassemia produce little or no HbA, while those with 
sickle-cell anemia produce structurally aberrant HbA. Complications of 
sickle-cell anemia include stroke, aplastic crisis, pain and swelling, 
bacterial infections and organ damage.  Currently, medical efforts to treat 
sickle-cell anemia are directed towards intervention in acute crises and 
prevention of respiratory infections.  Patients with


                                      4

<PAGE>

severe symptoms may require several hospitalizations a year.  Patients with 
- -Beta--thalassemia require transfusions to sustain life, but the onset of 
iron overload may result in disability or death in many patients by early 
adulthood.  To date, no effective conventional therapy exists for 
- -Beta--thalassemia, and treatment is limited to management of symptoms and 
complications of both the disease and its treatments.

Limited clinical studies have demonstrated that agents which increase 
cellular levels of fetal hemoglobin ("HbF") reduce disease symptoms in 
patients with sickle-cell anemia.  Whether the change in HbF levels is the 
proximate cause of, or in any way a contributing factor to, the reduction in 
symptoms is not certain.  In laboratory tests, Novaheme appears to markedly 
increase levels of HbF expression, as well as the percentage of blood cells 
that express HbF, and is distributed widely when given intravenously, with 
certain dosing regimens. In addition, EX VIVO studies conducted on a human 
red blood cell line have shown Novaheme to be more potent than butyric acid, 
hydroxyurea, and isobutyramide in increasing HbF levels.  While these results 
are encouraging, there can be no assurance that EX VIVO increases in HbF will 
predict similar changes IN VIVO, will predict improvement in symptoms, or 
that patients will otherwise benefit from such changes.

The Company was recently awarded U. S. Patent No. 5,569,675 covering the use 
of Novaheme for the treatment of serious blood disorders such as sickle cell 
disease or -Beta--thalassemia.  The Company is currently seeking a 
development partner for this product. There can be no assurance that the 
Company will be successful in identifying a suitable partner.

AN10 TOPICAL

The Company is also pursuing a development program with a topical formulation 
of AN10 ("AN10 Topical").  Recent animal studies suggest that AN10 Topical 
may prove to have potential utility in reducing chemotherapy-induced 
alopecia, or hair loss, in patients with cancer.  The Company expects to 
complete certain animal and laboratory testing, and plans to file an IND for 
AN10 Topical during the first half of 1997.  There can be no assurance that 
the ongoing animal and laboratory testing will be successful or will be 
completed in a timely manner. Accordingly, there can be no assurance that the 
IND will be filed in a timely manner or at all, and no assurance that the FDA 
will approve the IND if one is filed.

APAFANT

Apafant was originally developed by Boehringer Ingelheim as an oral treatment 
for asthma.  Boehringer Ingelheim has previously conducted extensive clinical 
trials in the US and in other countries using the oral form of the drug.  

Ansan is now pursuing a development program for an injectable formulation of 
apafant for the treatment of acute pancreatitis.  Acute pancreatitis is an 
inflammation of the pancreas. Its causes include gallstones, alcohol abuse 
and infection. Patients with moderate to severe pancreatitis receive only 
supportive care in an intensive care unit.  During an episode of 
pancreatitis, patients are at risk of organ failure, including loss of lung, 
kidney and liver function.  In a significant number of cases pancreatitis is 
fatal.  There  is currently no FDA approved therapy for the treatment of 
pancreatitis.

Apafant is a platelet activating factor ("PAF") antagonist.  PAF is an 
inflammatory substance produced in the body that is known to play a role in 
acute pancreatitis. In certain experiments, acute pancreatitis, and the 
resulting end organ damage and failure, can be induced in laboratory animals 
by the injection of PAF.  Treatment with apafant has been demonstrated to 
protect laboratory animals in certain models of PAF-induced organ damage, as 
well as other models of multiple organ system failure.  The Company believes 
that a drug that can prevent organ damage and  failure could be beneficial in 
treating patients with pancreatitis. 

The Company plans file an IND for apafant for acute pancreatitis during 1997. 
There can be no assurance that the IND will be filed in a timely manner or at 
all and no assurance that the FDA will approve the IND if one is filed. 

LICENSE AGREEMENTS

The Company has obtained, from Bar-Ilan Research and Development Co., Ltd.
("Bar-Ilan") in Israel, an exclusive worldwide license (the "Bar-Ilan License"),
to a United States patent and corresponding foreign patents and patent
applications covering AN9 and other butyric acid analogs, and a United States
patent directed to the use of AN10 and other butyric acid analogs to treat
hemaglobinopathies.  The Bar-Ilan License provides for the payment by the


                                      5

<PAGE>

Company to Bar-Ilan of royalties based on sales of products and processes 
incorporating the licensed technology, subject to minimum annual amounts 
which commenced in 1995, as well as a percentage of any income derived from 
any sublicense of the licensed technology.  The Company must also pay all 
costs and expenses incurred in patent prosecution and maintenance.  The 
minimum annual royalty for 1996 was $15,000,  and will increase annually.  
The minimum annual royalty will be $20,000 and $25,000 for 1997 and 1998 
respectively and $60,000 per annum for 1999 and beyond.

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

In May of 1996, the Company signed a licensing agreement with Boehringer 
Ingelheim to acquire the rights in the United States and the European Union 
to develop a new intravenous formulation of the drug apafant for all clinical 
indications.  Pursuant to the agreement, the Company may be obligated to make 
future milestone and royalty payments to Boehringer Ingelheim.  However, 
under certain circumstances, Boehringer Ingelheim may participate in the 
further development and commercialization of apafant and, in such 
circumstances, would be obligated to make milestone and royalty payments to 
Ansan.

SCIENTIFIC ADVISORS

Since the Company's inception, the Company has sought the advisory services 
of a number of scientists, researchers and clinicians with extensive 
experience in the Company's fields of interest (the "Scientific Advisors").  
The Scientific Advisors have assisted the Company in identifying scientific 
and product development opportunities, in reviewing and evaluating with 
management the progress of research programs, and in recruiting and 
evaluating scientists and other employees.  It is expected that the 
Scientific Advisors will continue to meet with management and key scientific 
employees of the Company in groups or individually on an informal basis.

PATENTS AND PROPRIETARY RIGHTS

The Company's success will depend, in part, on its ability, and the ability 
of its licensor(s), to obtain protection for its products and technologies 
under United States and foreign patent laws, to preserve its 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 the Company's potential products which have been licensed by the 
Company from Bar-Ilan, or that it may license from others in the future, will 
result in patents being issued, that any issued patents will afford adequate 
protection to the Company or not be challenged, invalidated, infringed or 
circumvented, or that any rights granted thereunder will afford additional 
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 also 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 in suits brought against it or 
any of its 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 the Company's 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 its products and technologies.  No assurance can be given that any 
licenses required under any such patents or proprietary rights would be made 
available on terms acceptable to the Company, if at all.

The Company is aware of the existence of prior art references which may 
affect the validity of certain claims in the issued patent, which claims 
broadly cover AN10, among other compounds.  Reexamination of such patent by 
the U.S. Patent and Trademark Office ("PTO"), in light of these references, 
may be necessary in order to obtain valid


                                      6

<PAGE>

claims which are both free of the prior art and which specifically cover 
AN10.  In the course of preparing for reexamination or otherwise, additional 
prior art may be uncovered which might affect the validity of such proposed 
narrow claims.  Such art would need to be brought to the attention of the 
PTO, in connection with any reexamination.  Moreover, there can be no 
assurance that the PTO will grant a request for reexamination, or if granted, 
that such reexamination will result in the issuance of the desired claims.  
In any event, given that the already-uncovered prior art references relate to 
compounds but not to methods of treatment, the existence of such references 
would not, as a matter of U.S. patent law, be expected to affect any claims 
directed to the use of AN10 to treat fetal hemoglobinopathies as covered in 
U.S. Patent No. 5,569,675 issued in October 1996, which the Company has 
licensed from Bar-Ilan.

The Company is also aware of other patents (the "Perrine patents") which 
appear to cover the administration of butyric acid, during gestation or 
infancy, to ameliorate -Beta--globin disorders, including sickle cell anemia 
and -Beta--thalassemia, by increasing the level of fetal hemoglobin.  To the 
extent that AN10 converts to butyric acid and in the event the Company's 
commercial activities include administration of AN10 during gestation and/or 
infancy, such activities could give rise to issues of infringement of the 
Perrine patents.

The Company also relies on trade secrets and proprietary know-how, which it 
seeks to protect, in part, by confidentiality agreements with its employees, 
consultants, advisors, and others.  There can be no assurance that employees 
of the Company, consultants, advisors, or others, will maintain the 
confidentiality of such trade secrets or proprietary information, or that the 
trade secrets or proprietary information 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. 

SUPPLIERS

The Company currently obtains from outside suppliers the supplies (I.E., drug 
substance) of Pivanex and Novaheme necessary to create the formulations for 
use in its research and development efforts.  The Company believes that such 
drug substances are relatively easy and inexpensive to synthesize when 
compared with many other products on the market or currently in development 
by others and that there are numerous vendors that could manufacture Pivanex 
and Novaheme. Nevertheless, there can be no assurance that such vendors will, 
in fact, agree to perform the requested activities for the Company. There can 
be no assurance, furthermore, that the Company will not experience delays or 
other supply problems that may materially adversely affect the Company's 
research and development efforts or that the Company will be able to obtain 
an alternate source of supply on a timely basis.

MANUFACTURING AND MARKETING

The Company neither has nor may have in the foreseeable future the resources 
to manufacture or directly market on a commercial scale any products that it 
may develop.  In connection with its research and development activities, the 
Company may seek to enter into collaborative arrangements with larger 
pharmaceutical, health care or chemical companies to assist in funding the 
substantial development costs associated with bringing drug products to 
market. These entities may also be responsible for commercial scale 
manufacturing, which will be subject to applicable FDA regulations (see 
"Government Regulation"). The Company anticipates that such arrangements may 
involve the granting by it of exclusive or semi-exclusive rights to sell 
specific products to specified market segments or in particular geographic 
territories in exchange for a royalty or other financial considerations.

To date, the Company has not entered into any commercial manufacturing or 
marketing agreements for any of its proposed products.  There can be no 
assurance that the Company will be able to enter into any such arrangements 
on favorable terms, or at all.  Such collaborative marketing arrangements, 
whether licenses, joint ventures or otherwise, may result in lower revenues 
than would otherwise be generated if the Company conducted the marketing of 
its own products.  To the extent that the Company ultimately determines to 
undertake commercial scale manufacturing or direct marketing activities, it 
will require substantial additional personnel and financial resources.

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


                                      7

<PAGE>

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.

The Company is aware that Alpha Therapeutics Corporation ("Alpha") is 
currently developing, through technology covered by the Perrine patents, a 
butyrate-related treatment for blood disorders that would directly compete 
with the Company's Novaheme product.  The Company has also become aware of 
recently published clinical results regarding arginine butyrate, another 
butyrate-related treatment for blood disorders that would directly compete 
with the Company's Novaheme product, which results suggest that when arginine 
butyrate is given intravenously for several weeks to a small number of 
patients, it does not significantly increase blood hemoglobin levels.  There 
can be no assurance that Novaheme will prove to be more efficacious in the 
treatment of blood disorders than the drug under development by Alpha or than 
arginine butyrate or that, in the event that Novaheme is approved for 
commercialization, that Novaheme will gain wider market acceptance than the 
Alpha product.  In addition, Novaheme will face competition from hydroxyurea, 
a therapeutic agent currently marketed for other indications and which has 
just completed clinical testing for the treatment of blood disorders.  
Although the Company believes that hydroxyurea will only have limited 
effectiveness in the treatment of hemoglobinopathies since initial studies 
have shown it to be toxic and, in certain experimental models, less effective 
than Novaheme at increasing the EX VIVO expression of HbF levels, there can 
be no assurance that Novaheme will ultimately prove to be more efficacious at 
treating blood disorders than hydroxyurea or that, in the event that Novaheme 
is approved for commercialization, that it will gain wider market acceptance 
than hydroxyurea.

In addition, 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

The Company's research and development activities are, and the production and 
marketing of the Company's 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, record keeping, 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 the 
Company to enter into government supply contracts, withdrawal of previously 
approved applications and criminal prosecution.

In order to obtain FDA approval of a new drug, the 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 preclude the Company
from marketing any products it may develop.  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.


                                      8

<PAGE>

The FDA may also require post-marketing testing and surveillance of approved 
products, or place other conditions on its 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 Federal Food, Drug, and Cosmetic Act and the regulations promulgated 
thereunder govern the testing, manufacture, safety, effectiveness, labeling, 
storage, record keeping, approval, advertising and promotion of new drugs.  
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.

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.

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 Company's 
proposed products, cause the Company to undertake costly procedures and 
furnish a competitive advantage to more substantially capitalized companies 
with which the Company expects to compete.  In addition, the extent of 
potentially adverse government regulations which might arise from future 
administrative action or legislation cannot be predicted.

RELATIONSHIP WITH TITAN PHARMACEUTICALS, INC.

The Company was founded as a wholly-owned subsidiary of Titan 
Pharmaceuticals, Inc. ("Titan").  Certain officers and directors of Titan 
serve as directors of the Company.  Since the Company's inception, Titan has 
provided certain executive, administrative, financial, business development 
and regulatory services to the Company.

In March 1997, the Company entered into a financing agreement with Titan.  
The agreement included an initial payment to the Company of $1,000,000 in 
exchange for a one-year note issued to Titan.  Titan may convert the note 
into Ansan common stock at a predetermined price for a period of ninety days. 
In conjunction with the financing agreement, Titan was issued an option to 
purchase additional common stock of the Company at a predetermined price for 
a period of ninety days.  As part of the financing agreement Titan will, 
under certain circumstances, acquire additional rights to purchase Ansan 
common stock, and under other circumstances, be obligated to purchase Ansan 
common stock.  (See "Item 12 - Certain Relationships and Related 
Transactions" and "Item 11 - Security Ownership of Certain Beneficial Owners 
and Management.")

EMPLOYEES

The Company currently has seven full-time employees.  The Company's future 
success depends in significant part upon the continued service of its key 
scientific personnel and executive officers and its 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 
the Company can retain its key employees or that it can attract, assimilate 
or retain other highly qualified technical and managerial personnel in the 
future.

ITEM 6.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

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 other sources.

RESULTS OF OPERATIONS

Since its inception in November 1992, the Company's efforts have been 
principally devoted to research and development, securing patent protection 
and raising capital.  From the inception through December 31, 1996, the 
Company has incurred an accumulated deficit of $9,080,000.  These losses have 
resulted from expenditures for research and development and general 
administrative activities including legal and professional activities, and 
are expected to continue for the foreseeable future.  Through December 31, 
1996, research and development expenses totaled $5,584,000, and general and 
administrative expenses totaled $2,914,000.

Research and Development expenses for 1996 were $1,181,000, as compared to 
$1,421,000 for 1995, a decrease of $240,000, or 17%.  The higher level of 
expenditures in 1995 is attributed to costs incurred in anticipation of the 
Company's clinical trial that commenced in the first quarter of 1996.  These 
costs included expenditures for preparation and compilation of the IND, 
toxicology studies and manufacturing.  Also, during the second of half of 
1995, the Company reorganized much of its research and development activities 
that are performed by outside vendors by establishing new vendor 
relationships, and moving certain functions in-house.  This reorganization 
has resulted in a cost savings to the Company.

General and administrative expenses for 1996 were $1,257,000, as compared to
$1,048,000 for 1995, an increase of $209,000, or 20%.  The increase can be
attributed to an issuance of stock to a member of management, a portion of


                                     11

<PAGE>

which was allocated to general and administrative expenses.  In addition, the 
1996 expenses reflect post-IPO expenditures such as investor relations and 
directors and officers insurance.

As a result of the foregoing expenses, the Company incurred an operation loss 
of $2,438,000 during 1996 compared with $2,469,000 during 1995.  The Company 
expects to continue to incur substantial research and development costs in 
the future as a result of funding ongoing (i) research and 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.  
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.

Other income includes interest income of $157,000 during 1996 as compared to 
$78,000 during 1995. The increase was a result of a substantial increase in 
the amount of cash and short-term investments subsequent to the Company's IPO 
in August 1995.  Interest expense was $431,000 during 1995 which included a 
non-cash charge of $400,000 relating to a discount attributed to Class A 
Warrants issued in a bridge financing of debt securities prior to the 
Company's IPO.

In May 1996, the Company signed a license agreement with Boehringer Ingelheim 
GmbH to acquire the rights in the United States and the European Union to 
develop a new intravenous formulation of the drug apafant for all clinical 
indications.

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

LIQUIDITY AND CAPITAL RESOURCES

Ansan is party to a master capital equipment lease, and the Company and three 
other majority-owned subsidiaries of Titan have entered into a sublease and 
assignment with Titan under such lease for which the Company is jointly and 
severally liable.  At December 31, 1996, the amount outstanding under the 
equipment lease was $747,000, with monthly payments of $30,459.

In March 1997, Titan and Ansan entered into an agreement for financing 
pursuant to which Titan advanced Ansan $1,000,000 in return for a debenture 
(the "Debenture") which is convertible at any time prior to June 21, 1997 
into 333,333 shares of common stock. The Debenture bears interest at prime 
plus 2% and is due in March 1998. In connection with the issuance of the 
Debenture, Ansan granted Titan an option (the "First Option") to acquire an 
additional 333,333 shares of Ansan common stock for an aggregate purchase 
price of $1,000,000. The First Option expires on June 21, 1997.

In the event the Debenture is converted to equity, Ansan will grant Titan two 
additional options (respectively, the "Second Option" and the "Third 
Option"). The Second Option will be exercisable for two years from the date 
to purchase up to 1,630,000 shares of Ansan common stock at an exercise price 
of $3.75 per share. The Third Option will be exercisable through August 8, 
2000 to purchase up to 500,000 additional shares at an exercise price of 
$6.50 per share. Titan will be obligated to exercise the Second Option for 
the purchase of specified numbers of shares in the event Titan's outstanding 
Class A Warrants are exercised, provided Ansan has not completed public or 
private equity financings resulting in specified gross proceeds prior to the 
date such a purchase obligation arises.

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 fundraising activities over at
least the next several years.  While the Company believes that its current
capital resources will be sufficient


                                     12

<PAGE>

to sustain its planned operations for approximately one year, the company 
will be required to seek additional financing to continue its activities 
beyond that period.  However, the Company's capital requirements may change 
depending on numerous factors including, but not limited to, the progress of 
research and development programs, the results of clinical studies, the 
timing of regulatory approvals, technological advances, determinations as to 
the commercial potential of the Company's products, and the status of 
competitive products.  In addition, expenditures will be dependent upon 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.  In the event that the 
Company fails to raise any funds it requires, it may be necessary for the 
Company to out-license rights it would prefer to retain, or to significantly 
curtail its activities or cease operations.

more than 10% of a registered class of the Company's equity securities to 
file with the Securities and Exchange Commission (the "SEC") 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

                            EMPLOYMENT AGREEMENTS

annual increases in accordance with Company policies, in addition to an 
automatic cost of living adjustment based upon the consumer price index.  In 
addition, under the terms of the Shalson Employment Agreement, the Company is 
obligated to pay Mr. Shalson a bonus equal to 4% of the net proceeds paid to 
the Company by institutional investors and corporate partners he secures 
within the first two years of his employment.  Such payments are subject to a 
limitation of 8% of the total net proceeds received by the Company for any 
such investment when combined with other fees payable to third parties in 
connection with any such financing and certain other exceptions contained in 
the agreement.  The Company also issued to Mr. Shalson, pursuant to the 
Shalson Employment Agreement, options to purchase an aggregate of 132,000 
shares of the Company's Common Stock, at an exercise price of $3.00 per 
share.  The options granted will vest as to 16,500 shares on August 15, 1997 
and the balance of 115,500 shares will vest in forty-two equal monthly 
installments thereafter.  The Shalson Employment Agreement provides that in 
the event Mr. Shalson's employment is terminated without good cause (as 
defined), the Company will pay Mr. Shalson severance equal to six months' 
base salary if the termination occurs during the first two years and 12

to offset by other salary received by Mr. Shalson.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

Louis R. Bucalo, Chairman of the Company's Board of Directors, is also 
President, Chief Executive Officer and a member of the Board of Directors of 
Titan, the majority stockholder of the Company.  Lindsay A. Rosenwald, a 
director of the Company, is also a member of the Board of Directors of Titan.

In 1992, Titan purchased 327,446 shares of Common Stock of the Company for 
nominal consideration.  In May 1994, Titan purchased 532,651 shares of the 
Company's Series A Preferred Stock for $992,592 in cash and the forgiveness 
of a debt in the amount of $1,449,064, which shares were converted into 
532,651 shares of Common Stock upon completion of the IPO.  In connection 
with Titan's purchase of the Series A Preferred Stock of the Company, Titan 
was granted the right, exercisable in prescribed circumstances, to demand or 
to participate in certain registrations of the Company's securities under the 
Securities Act of 1933.


                                     18

<PAGE>

From its inception in November 1992 until May 1995, the Company received 
loans from Titan to enable it to fund its operations.  At March 31, 1995, the 
aggregate amount of such loans outstanding was $1,551,252.  Upon the closing 
of the IPO, the March 31, 1995 balance was converted into shares of the 
Company's Common Stock at the conversion rate of $4.40 per share.  From April 
1995 through May 1995, Titan made additional non-interest bearing working 
capital advances to the Company in the aggregate amount of $108,280, which 
amount were repaid with cash.

Since the Company's inception, Titan has provided certain executive, 
administrative, financial, business development and regulatory services to 
the Company.  The Company pays Titan for such services on a quarterly basis.  
The Company also pays for any out-of-pocket expenses incurred by Titan in 
providing the services to the Company.  During the period from inception 
through December 31, 1993, the year ended December 31, 1994, the year ended 
December 31, 1995, and the year ended December 31, 1996, the Company incurred 
expenses in the aggregate of  approximately $205,000, $523,000, $376,000 and 
$57,000 respectively, pursuant to the services arrangement.  Furthermore, the 
Company uses certain facilities and equipment leased by Titan and reimburses 
Titan on a quarterly basis for the expenses incurred by Titan with respect to 
such use, in addition to having entered an assignment and sublease with 
Titan, along with the other subsidiaries of Titan, under the equipment lease 
to which Titan is a party.  At December 31, 1996, the amount outstanding 
under the equipment lease was approximately $747,000.

In July 1994, Louis R. Bucalo, Chairman of the Board of the Company, received 
options to purchase 15,052 shares of Common Stock at an exercise price of 
$.29 per share.

In May 1994, nine members of Titan's Board of Directors, including Lindsay A. 
Rosenwald a director of the Company, each received options under the 
Company's 1993 Stock Option Plan to purchase 335 shares of Common Stock at an 
exercise price of $.29 per share.

In March 1997, Titan and Ansan entered into an agreement for financing 
pursuant to which Titan advanced Ansan $1,000,000 in return for a debenture 
(the "Debenture") which is convertible at any time prior to June 21, 1997 
into 333,333 shares of common stock. The Debenture bears interest at prime 
plus 2% and is due in March 1998. In connection with the issuance of the 
Debenture, Ansan granted Titan an option (the "First Option") to acquire an 
additional 333,333 shares of Ansan common stock for an aggregate purchase 
price of $1,000,000. The First Option expires on June 21, 1997.

In the event the Debenture is converted to equity, Ansan will grant Titan two 
additional options (respectively, the "Second Option" and the "Third 
Option"). The Second Option will be exercisable for two years from the date 
to purchase up to 1,630,000 shares of Ansan common stock at an exercise price 
of $3.75 per share. The Third Option will be exercisable through August 8, 
2000 to purchase up to 500,000 additional shares at an exercise price of 
$6.50 per share. Titan will be obligated to exercise the Second Option for 
the purchase of specified numbers of shares in the event Titan's outstanding 
Class A Warrants are exercised, provided Ansan has not completed public or 
private equity financings resulting in specified gross proceeds prior to the 
date such a purchase obligation arises.

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 stockholders 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
Ansan Pharmaceuticals, Inc.

     We have audited the accompanying balance sheets of Ansan 
Pharmaceuticals, Inc. (a development stage company) as of December 31, 1995 
and 1996, and the related statements of operations, stockholders' equity (net 
capital deficiency), and cash flows for the years then ended and for the 
period from incorporation (November 6, 1992) to December 31, 1996.  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 financial position of Ansan 
Pharmaceuticals, Inc. (a development stage company) at December 31, 1995 and 
1996, and the results of its operations and its cash flows for the years then 
ended and for the period from incorporation (November 6, 1992) to December 
31, 1996 in conformity with generally accepted accounting principles.

                                                  ERNST & YOUNG LLP

                          ANSAN PHARMACEUTICALS, INC
                        (a development stage company)
                        NOTES TO FINANCIAL STATEMENTS


1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY

     Ansan Pharmaceuticals, Inc. (the "Company") was incorporated in the 
State of Delaware on November 6, 1992 to engage in the development of analogs 
of butyric acid for the treatment of cancer, blood disorders and other 
serious diseases.

    RELATIONSHIP WITH TITAN PHARMACEUTICALS, INC.

     Titan Pharmaceuticals, Inc. ("Titan"), a biopharmaceutical company 
engaged, through the operations of its subsidiaries and affiliates, in the 
development of new proprietary therapeutic products for use in the fields of 
cancer, immunology, viral diseases, and disorders of the central nervous 
system, was the Company's parent until the Company's initial public offering 
(the "Offering") in August 1995 (see Note 5).  Immediately subsequent to the 
Offering, Titan's interest was reduced to a 44%.  Through December 31, 1996, 
the Company contracted with Titan for facilities and equipment, and certain 
administrative, financial, regulatory, business development and human 
resource services. Titan has previously supplied working capital financing to 
the Company and may in the future provide such financing.  At December 31, 
1996, Titan owned approximately 43% of Ansan.  Certain members of Titan's 
management and/or Board of Directors are also members of the Company's Board 
of Directors.

    BASIS OF PRESENTATION

     The Company's activities since incorporation have primarily consisted of 
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, and expects to incur increasing losses and require additional 
financial resources to achieve commercialization of its products.

   The Company is engaged in a number of long-term development projects which 
involve experimental technologies.  The Company has incurred losses since 
inception of $9.1 million and expects such losses to continue for at least 
the next several years.  The projects may require substantial expenditures 
and take a number of years to develop prior to commercialization. Therefore, 
the Company will need to obtain additional funds to continue its research and 
development activities, fund operating expenses, pursue regulatory approval, 
and build production, sales, and marketing activities, as necessary. Sources 
of capital may include the issuance of equity or debt securities to Titan or 
others (See Note 8), and collaborative agreements. Management believes 
sufficient capital will be available to achieve planned business objectives 
through at least 1997.

   In May 1995, the board of directors and stockholders of the Company 
authorized a 0.1723399-for-one reverse stock split.  Prior to the Offering, 
each share of Series A preferred stock and common stock were split into 
0.1723399 shares of preferred stock and common stock, respectively.  The 
accompanying financial statements are adjusted to reflect the stock split on 
a retroactive basis.


                                     F-8

    USE OF ESTIMATES

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

    CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     The Company considers all highly liquid investments purchased with an 
original maturity of 90 days or less to be cash equivalents.  Cash 
equivalents included $11,808 in money market funds at December 31, 1996.

     At December 31, 1995 and 1996, the Company had $3,809,000 and 
$1,500,000, respectively, of auction rate preferred stock (preferred stock in 
money market mutual funds), classified as "available for sale."  These 
amounts are stated at cost which approximate estimated fair 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.  Leasehold improvements are amortized over the 
remaining period of the lease.

    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 
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.

    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.

    NET LOSS PER SHARE

     Net loss per share is computed using the weighted average number of 
common shares outstanding.  Common equivalent shares are excluded from the 
computation as their effect is antidilutive, except that, pursuant to the 
Securities and Exchange Commission ("SEC") Staff Accounting Bulletins, common 
equivalent shares (stock options, warrants and preferred stock) issued during 
the period commencing 12 months prior to March 31, 1995 at prices below the 
public offering price have been included in the calculation as if they were 
outstanding for all periods presented (using the treasury stock method for 
stock options and the if-converted method for the assumed conversion of the 
payable to Titan as of March 31, 1995).  However, shares to be held in escrow 
are not treated as outstanding for any period (see Note 5.) Net loss per 
share calculated on this basis for the year ended December 31, 1995 was $2.28

     Pro forma net loss per share has been computed as described above and 
also gives effect, pursuant to SEC policy, to common equivalent shares from 
convertible preferred stock issued more than 12 months prior to the IPO that 
automatically converted upon completion of the Company's IPO (using the 
if-converted method) from the original date of issuance.

</TABLE>

     Depreciation expense was $1,659 and $22,323 for the years ended December 
31, 1995 and 1996, respectively.

3.  SPONSORED RESEARCH AND LICENSE AGREEMENTS

     In July 1994, the Company entered into a research agreement with a 
university.  Under the terms of the agreement, the Company agreed to fund 
research of $105,700 through December 31, 1994.  The agreement was extended 
six months beyond the original term to allow for completion of the scope of 
the research program.  During the year ended December 31, 1995, the Company 
incurred sponsored research expenses of $62,000 related to this agreement.

     In 1992, the Company entered into research and license agreements with 
Bar-Ilan Research and Development Company, Ltd. ("Bar-Ilan"), an entity 
located in Israel.  The research agreement expired during 1994.  Pursuant to 
the license agreement, the Company receives certain exclusive worldwide 
licenses to inventions and confidential information related to the research 
program in exchange for the research funding and specified royalties on 
future sales and/or sublicensing arrangements.  To maintain license 
exclusivity, the Company made royalty payments of $10,000 and $15,000 in 1995 
and 1996, respectively.  The Company is obligated to make minimum royalty 
payments of $20,000 in 1997, $25,000 in 1998 and $60,000 in each calendar 
year thereafter. In connection with this license agreement, Bar-Ilan 
also entered into a stock purchase agreement with the Company.

     In May 1996, the Company signed a licensing agreement with Boehringer 
Ingelheim GmbH ("Boehringer") to acquire the rights in the United States and 
the European Union to develop a new intravenous formulation of the drug 
ApafantTM for all clinical indications.  The Company intends to proceed with 
further development and, if possible, clinical testing of the drug.  Pursuant 
to the agreement, the Company made a license payment of $50,000 in 1996, and 
may be obligated to make future milestone and royalty payments to Boehringer. 
 However, under certain circumstances, Boehringer may participate in further 
development and commercialization of ApafantTM and, in such circumstances, 
would be obligated to make milestone and royalty payments to Ansan.

4.  LEASES

     The Company leases facilities under an operating lease that expires in 
December 1998.  Rent expense totaled $56,831 for the year ended December 31, 
1996.  Future minimum lease payments total $54,479 for the years ending 
December 31, 1997 and 1998.

5.  STOCKHOLDERS' EQUITY

    PREFERRED STOCK

     In May 1994, the Company issued 532,651 shares of Series A Preferred 
Stock to Titan for cash of $992,592 and in exchange for forgiveness of a 
payable to Titan of $1,449,064.  Concurrent with the Offering, the preferred 
stock automatically converted into 532,651 shares of common stock.

    UNIT OFFERING

     In August 1995, the Company issued 1,300,000 units, at $5.00 per unit in 
the Offering.  Each unit consisted of one share of common stock, one 
redeemable class A warrant, and one class B warrant.  The net proceeds (after 
underwriter's discount and expenses, and other costs associated with the 
Offering) totaled $5,107,000.  At the closing of the Offering, all of the 
Company's outstanding preferred stock automatically converted into 532,651 
shares of common stock, and the Company issued 352,557 shares of common stock 
to Titan in exchange for forgiveness of $1,551,252 of intercompany debt.  In 
September 1995 the Company issued an additional 195,000 units, at $5.00 per 
share, in accordance with the underwriter's over-allotment option.  The net 
proceeds from the exercise of the underwriter's over-allotment option (after 
underwriter's discount and expenses) totaled $848,250.  Each class A warrant 
entitles the holder to purchase one share of common stock and one class B 
warrant at an exercise price of $6.50 per share.  Each class B warrant 
entitles the holder to purchase one share of common stock an exercise price 
of $8.75 per share.

     In connection with the Offering, the holders of the Company's common 
stock and options to purchase common stock placed, on a pro rata basis, 
363,740 shares and options to purchase 36,260 shares of common stock into 
escrow (the "Escrow Shares" and "Escrow Options", respectively).  The Escrow 
Shares and Escrow Options are not transferable or assignable; however, the 
Escrow Shares may be voted.  Holders of Escrow Options may exercise their 
options prior to their release from escrow; however, the shares issuable upon 
any such exercise will continue to be held in escrow.  The Escrow Shares and 
Escrow Options will be released from escrow if, and only if, certain earnings 
or market price criteria have been met.  If the conditions are not met by 
March 31, 2000, the Escrow Shares and Escrow Options will be canceled and 
contributed to the Company's capital.

     The release of Escrow Shares and Escrow Options held by employees, 
officers, directors, consultants and their relatives will be deemed 
compensatory.  Accordingly, the Company will recognize as compensation 
expense, during the period in which the earnings or market price targets are 
met, a one-time charge to reflect the then fair market value of the shares 
released from escrow.  Such charges could substantially reduce the Company's 
net income or increase the Company's loss.  The amount of compensation 
expense recognized by the Company will not affect the Company's total 
stockholders' equity.

    BRIDGE LOAN WARRANTS

     In May and June 1995, the Company completed a bridge financing with 
gross proceeds of  $1,425,000.  In conjunction with the bridge notes, the 
Company issued class A warrants to purchase an aggregate of 712,500 shares of 
Common Stock.  In 1995, the Company recognized a $400,000 charge related to 
the issuance of the warrants.  The principal and accrued interest on the 
bridge notes were repaid out of the proceeds from the Offering.

     COMMON STOCK

      During 1996, the Company issued 40,000 shares of common stock to an 
employee, resulting in $323,000 in compensation expense.

     STOCK PURCHASE AGREEMENTS

      Through December 31, 1996, the Company has issued 18,095 shares of 
common stock to officers, employees and consultants under stock purchase 
agreements. Certain shares are subject to repurchase by the Company, as 
determined by the board of directors, at the original issuance price.  The 
repurchase rights will lapse as the shares vest over a period of five years 
from the issuance date. During 1996, the Company exercised its repurchase 
rights with respect to 804 shares.  At December 31, 1996, 1,178 shares are 
subject to repurchase.

    STOCK OPTION PLAN

     Under the Company's 1993 Stock Option Plan which was amended and 
restated (the "1993 Plan"), pursuant to which incentive stock options may be 
granted to employees, and nonstatutory stock options may be granted to 
employees, directors, consultants and affiliates of the Company.  A total of 
141,710 shares of Common Stock has been reserved and authorized for issuance 
under the 1993 Plan.  No further options will be granted under the Company's 
1993 Plan.  In May 1995, the Company adopted the 1995 Stock Option Plan (the 
"1995 Option Plan"). A total of 150,000 shares of Common Stock are reserved 
and authorized for issuance under the 1995 Option Plan.  

     Options granted under the 1993  and 1995 Plans expire no later than ten 
years from the date of grant, except when the grantee is a 10% shareholder of 
the Company or an affiliate company, in which case the maximum term is five 
years from the date of grant.  The exercise price shall be at least 100%, 85% 
and 110% of the fair value of the stock subject to the option on the grant 
date, as determined by the board of directors, for incentive stock options, 
nonstatutory stock options and options granted to 10% shareholders of the 
Company or affiliate company, respectively.  Options granted under the 1993 
Option Plan 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 as the shares vest over a period 
of five years from the date of grant.

Activity under the 1993 and 1995 Option Plans is summarized below:

     The Company recorded deferred compensation of $277,784 for the 
difference between the grant price and the deemed fair value of the Company's 
common stock for certain options granted in the 12-month period prior to the 
offering.  The deferred compensation is being amortized to expense over the 
vesting period of the options.

     From incorporation through December 31, 1994, the Company issued options 
for 12,066 shares outside the 1993 Plan at exercise prices ranging from $0.06 
to $0.29.  These options are exercisable immediately upon grant; however, 
the shares issuable upon exercise of the options are subject to repurchase by 
the Company.  Such repurchase right will lapse as the shares vest over a 
period of three to five years from the date of grant.

     The following table summarizes information about options outstanding at 
December 31, 1996:

</TABLE>

     Of the 129,770 options outstanding at December 31, 1995, 36,607 were 
exercisable at that date.  All options granted under the 1993 Plan are 
immediately exercisable, of which 44,532 shares of common stock underlying 
the options as of December 31, 1996 would be subject to repurchase by the 
Company should certain options be exercised and the optionee's employment or 
consulting relationship terminate.

    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 and loss 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 1996 and 1995:  weighted-average 
volatility factor of 0.7; no expected dividend payments; weighted-average 
risk-free interest rates in effect of 6.27% and 6.00%, respectively; and a 
weighted-average expected life of 4.04 and 4.46, 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, 1995 and 1996 was $0.77 
and $1.54, 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:

Pro forma net loss per share        $      (1.94)       $       (0.98)

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

6.  RELATED PARTY TRANSACTIONS

     On May 31, 1994, the Company entered into an agreement with Titan 
providing for the allocation of costs by Titan to the Company for certain 
services provided during 1994 and 1995 in managing the affairs of the 
Company, consisting primarily of occupancy and equipment charges.  These 
expenses are allocated among Titan and Titan's subsidiaries and affiliates 
based upon the relative percentage of effort expended by Titan on each 
subsidiary's affairs and relative use of assets held by Titan, including 
those under a master capital equipment lease.  Management believes these 
allocations to be reasonable.

     Research and development expenses allocated to the Company from Titan 
were approximately $114,000 for the year ended December 31, 1995.  General 
and administrative expenses allocated to the Company were $398,000 and 
$57,000 for the years ended December 31, 1995 and 1996, respectively.

     No interest has been charged on the net payable to Titan.  Activity 
under the payable to Titan is summarized as follows:

     LEASE COMMITMENT

      Titan is party to a master capital equipment lease, pursuant to which 
the Company and three other Titan majority-owned subsidiaries are jointly and 
severally liable under a sublease and assignment agreement for monthly 
payments (currently totaling $30,459) under the lease, should Titan be unable 
to service the equipment lease.  As of December 31, 1996, the amount 
outstanding under the lease was approximately $747,000.

7.  INCOME TAXES

     As of December 31, 1996, the Company had federal net operating loss 
carryforwards of approximately $8,600,000.  The Company also had federal 
research and development tax credit carryforwards of approximately $200,000.  
The net operating loss and credit carryforwards will expire at various dates 
beginning in 2008 through 2011, if not utilized.

     Utilization of the net operating losses and credits may be subject to a 
substantial annual limitation due to the "change in ownership" provisions of 
the Internal Revenue Code of 1986 and similar state provisions.  The annual 
limitation may result in the expiration of net operating losses and credits 
before utilization.

     Significant components of the Company's deferred tax assets for federal 
and state income taxes are as follows:

     The net valuation allowance increased by $1,000,000 during the year 
ended December 31, 1995.

8.  SUBSEQUENT EVENTS

    UNAUDITED

     In March 1997, Titan and Ansan entered into an agreement for financing 
pursuant to which Titan advanced Ansan $1,000,000 in return for a debenture 
(the "Debenture") which is convertible at any time prior to June 21, 1997 
into 333,333 shares of common stock. The Debenture bears interest at prime 
plus 2% and is due in March 1998. In connection with the issuance of the 
Debenture, Ansan granted Titan an option (the "First Option") to acquire on 
additional 333,333 shares of Ansan common stock for an aggregate purchase 
price of $1,000,000.  The First Option expires on June 21, 1997.

     In the event the Debenture is converted to equity, Ansan will grant 
Titan two additional options (respectively, the "Second Option" and the 
"Third Option").  The Second Option will be exercisable for two years from 
the date of grant to purchase up to 1,630,000 shares of Ansan common stock at 
an exercise price of $3.75 per share.  The Third Option will be exercisable 
through August 8, 2000 to purchase up to 500,000 additional shares at an 
exercise price of $6.50 per share.  Titan will be obligated to exercise the 
Second Option for the purchase of specified numbers of shares in the event 
Titan's outstanding Class A Warrants are exercised, provided Ansan has not 
completed public or private equity financings resulting in specified gross 
proceeds prior to the date such a purchase obligation arises.
