PART I

Item 1.  Description of Business
- ------

     Somatogen is a biopharmaceutical company developing specialty 
oxygen therapeutics and other pharmacological agents utilizing its 
proprietary recombinant hemoglobin technology. The Company's lead 
recombinant hemoglobin molecule is rHb1.1. The Company's first 
proposed application of rHb1.1 is as an oxygen carrying pharmaceutical
designed to treat blood loss in surgery, which the Company proposes 
to market under the registered trademark "Optro." Concerns about 
transfusions with donated blood have created a significant need for 
a safe alternative. These concerns include transmission of infectious
diseases (such as AIDS and hepatitis), maintaining an adequate supply,
the need to type and cross-match prior to transfusion and transfusion-
related immunosuppression.

     In June 1994, Somatogen entered into a global strategic alliance 
with Eli Lilly and Company ("Lilly") whereby Lilly is co-developing 
Optro (the "Lilly Alliance") and in September 1995, Somatogen and 
Lilly agreed to amend certain terms of the Lilly Alliance. Under 
the terms of the Lilly Alliance, Lilly is responsible for establishing
manufacturing facilities to supply Optro for Phase III clinical trials 
and for global commercialization. In North America, the Company's 
expanded Phase II and Phase III trials for Optro will be performed in 
conjunction with Lilly's clinical and research groups, and Lilly and 
Somatogen will co-promote the product, splitting the development costs
and sharing equally in the profits. Outside North America, except in 
Scandinavia, Lilly will be responsible for clinical development of 
Optro and related costs, and will have exclusive marketing rights.
Lilly will pay Somatogen a royalty on product sales outside North 
America. Lilly has invested $30,000,000 in exchange for Somatogen 
Common Stock.  The Lilly Alliance originally contemplated a March 1996
determination date at which Lilly would have made a decision whether 
to proceed with the clinical development and commercialization of 
Optro.  The September 1995 amendment to the Lilly Alliance accelerated
$7,000,000 of the $10,000,000 equity investment which Lilly would have 
made at such determination date.  Pursuant to the amendment,  Lilly 
made such $7,000,000 equity investment in October 1995. In addition,

the amendment eliminated the March 1996 determination date and 
combined all remaining milestone equity investments into a single 
$7,000,000 milestone equity investment to be made if the joint 
Somatogen-Lilly steering committee for the alliance determines that
certain conditions have been met. The amendment also modified the 
termination provisions of the alliance, which provide for payment 
of certain financial consideration by Lilly to Somatogen in the 
event that the alliance is terminated under certain circumstances. 
Pharmacia & Upjohn, Inc. ("Pharmacia") has the marketing rights to 
Optro in Scandinavia under its 1991 agreement with Somatogen.

Background

  The Hemoglobin Molecule

     Blood is a complex fluid composed of several distinct types of 
cells suspended in plasma.  Red blood cells, which form the vast 
majority of blood's cellular population, are responsible for 
transporting and delivering oxygen throughout the body.  Hemoglobin 
is the portion of the red blood cell that captures oxygen in the 
lungs.  The red blood cell then transports the oxygen to the tissues 
where the oxygen is released and metabolized.

     Hemoglobin is a protein composed of four separate peptide 
chains (called "globins") with similar amino acid sequences: two alpha
chains and two beta chains.  Each globin chain combines with an 
iron-containing component (called "heme") to form the hemoglobin 
molecule.  The iron atom contained in each heme group directly 
binds one oxygen molecule, allowing four oxygen molecules to bind 
to each hemoglobin molecule.

     Variations in the amino acid sequence of the globin chain can 
influence the oxygen delivery characteristics of hemoglobin.  Variant
forms of hemoglobin are commonly referred to as "mutants." Hemoglobin 
mutants with a high oxygen affinity bind oxygen readily in the lungs 
but do not release oxygen as readily to the tissues.  Conversely, 
hemoglobin mutants with a low oxygen affinity bind oxygen somewhat 
less readily in the lungs but may release it more easily to the 
tissues.

SOMATOGEN, INC.

  Blood Transfusion

     Somatogen estimates that approximately 12.5 million units of red 
blood cells are transfused annually in the U.S.  The U.S. supply of 
red blood cells for transfusion is managed primarily by non-profit 
organizations that recruit donors, collect, screen and test blood, 
separate and purify its useful components and distribute the final 
product.  According to a 1992 study, the average direct cost of a 
unit of red blood cells was $205.  Based on such price, the Company 
estimates the total U.S. red blood cell transfusion market to be 
approximately $2.5 billion annually.  The Company estimates that 
international red blood cell transfusion markets represent at least an 
additional $2.5 billion annually.  The direct costs of red blood cell 
transfusion do not include the significant additional indirect costs 
of treating patients who incur complications resulting from adverse 
transfusion reactions and blood-borne infections.  The Company believes
that the price of a red blood cell substitute, if successfully 
developed, should reflect both direct and indirect costs of 
transfusion with red blood cells as well as any other specific 
therapeutic advantages that such product may have.

     Approximately 8.9 million units of red blood cells are transfused
annually in the U.S. as a treatment for blood loss as a result of 
surgery or other causes of acute blood loss.  The loss of blood during
surgery or from other acute causes reduces the body's ability to meet
the metabolic demands of the tissues and places additional stress on 
the cardiovascular system.  In patients who have suffered only mild to
moderate blood loss, cardiovascular stress can be mitigated and the 
metabolic demands of the tissues can be met through infusion of a 
volume-expanding solution such as saline or human serum albumin.  
However, in cases where a patient has lost greater amounts of blood, 
the reduction of the blood's oxygen-carrying capacity can have adverse
physiological effects.  At the present time, oxygen-carrying capacity 
can be enhanced only by a transfusion of red blood cells.

     The past decade has seen an increase in the incidence of 
blood-borne infectious diseases, such as AIDS and hepatitis, which 
has heightened the awareness of both health care professionals and 
patients to the inherent risks of blood transfusions.  Although new 
tests have been developed, such tests have not entirely eliminated 
the risk of infectious blood-borne disease transmission. In addition, 
















<PAGE>  6
SOMATOGEN, INC.


despite improved testing standards, human error still results in the 
release of contaminated units of blood.  Furthermore, some infectious
diseases are known to contaminate the blood supply but cannot be 
avoided because no reliable or cost effective diagnostic tests exist.
New infectious agents can suddenly appear in the blood supply, and it
can take years to develop a reliable test for such agents.  Several 
years elapsed between the appearance of AIDS and the development of 
a reliable test, and numerous patients contracted AIDS from 
transfusions during that time.  The current blood supply is 
dependent upon volunteer donors.  Increasingly stringent donor- 
screening criteria have caused the donor pool, and therefore the 
potential supply of blood, to contract.  As a consequence, the cost 
and intricacy of collecting, testing and storing blood has greatly 
increased in recent years.

     Red blood cell transfusions require complex typing and 
cross-matching to avoid potentially fatal reactions following 
transfusion.  An individual has a specific combination of major 
antigens (A, B, AB or O and Rh+ or Rh-) which naturally occur on 
the surface of each red blood cell.  Transfusion with red blood 
cells having antigens different from those of the recipient's red 
blood cells may result in serious and potentially fatal systemic 
reactions.  Accident victims and persons with rare blood types may 
die while awaiting compatible blood.  In addition, clerical error
continues to result in transfusion-related complications due to 
administration of the wrong blood type.

     Donated blood is fractionated to separate red blood cells from 
other blood components such as platelets and plasma.  However, a 
small quantity of white blood cells sometimes remains, which can 
cause delayed transfusion problems, such as graft-versus-host 
disease.  Donor blood also must be refrigerated or frozen, and 
when refrigerated it has a recommended shelf life of 35 to 42 
days.  These characteristics make it difficult to transfuse blood 
at an accident site or in an ambulance.





















<PAGE>  7
SOMATOGEN, INC.

     The problems associated with human donor blood have stimulated 
numerous efforts to reduce transfusions with donated blood.  The risk 
of blood-borne infectious disease has caused transfusion guidelines 
to be changed so that certain patients who historically would have 
received transfusions are no longer transfused.  Some hospital 
transfusion review committees have characterized a transfusion of 
donor blood as an "undesirable outcome" of surgery.  Certain patients 
in good health can elect to deposit their own blood prior to surgery,
potentially reducing or eliminating their need to receive donor blood.
In certain types of surgical procedures, lost blood can be collected, 
treated and reinfused, or blood loss can be reduced through the use 
of drugs. Modest blood loss can often be treated with a non-oxygen 
carrying fluid such as saline or human serum albumin.

     There have been numerous attempts to develop a red blood cell 
substitute, and a number of companies continue to actively pursue 
development of a red blood cell substitute. Hemoglobin extracted 
from human or bovine red blood cells ("stroma-free hemoglobin") has 
long been explored for such use.  However, stroma-free hemoglobin 
has several characteristics which must be corrected in order to  
make it suitable for use as a blood substitute.  First, when human 
hemoglobin is removed from the human red blood cell, its oxygen 
affinity increases, thereby causing the hemoglobin to bind oxygen 
too tightly and significantly reducing oxygen delivery to the tissues.
In order for human-derived stroma-free hemoglobin to be used as a red 
blood cell substitute, its oxygen affinity must be reduced by chemical
treatment resulting in additional cost to manufacture.  Such 
modification, however, is not required for bovine-derived hemoglobin.
Second, stroma-free hemoglobin tends to dissociate (or separate) into 
two alpha-beta globin pairs (called "dimers") which can be toxic to the
kidneys.  Dissociation can be avoided in stroma-free hemoglobin by 
chemically linking, polymerizing or otherwise chemically modifying 
the hemoglobin molecule resulting in additional cost to manufacture.
Recently, genetically engineered animals and plants (transgenic 
animals and plants) have been explored as potential sources of 
human-type hemoglobin.  Synthetic products designed to carry oxygen,
 such as perfluorocarbons ("PFCs"), have also been explored as 
potential red blood cell substitutes.  To date, no product based on 
stroma-free hemoglobin, transgenic plants or animals has been 
approved for human use as a blood substitute in the U.S.  See 
"Competing Technologies."

SOMATOGEN, INC.

Somatogen's Recombinant Hemoglobin Technology

     The Company believes it is a leader in characterizing the 
protein chemistry and molecular biology of the human hemoglobin 
molecule and in developing recombinant human hemoglobin.  Somatogen
believes that it is the only company to have successfully cloned, 
expressed and purified recombinant hemoglobin that binds oxygen in 
a manner similar to hemoglobin contained in human red blood cells.
The Company is using genetic engineering to develop other forms of 
hemoglobin with molecular characteristics designed to address 
specific clinical needs.
  
     Somatogen has used its proprietary recombinant hemoglobin 
technology to develop its first  potential product, Optro, an 
oxygen therapeutic designed to treat human blood loss in surgery. 
The U.S. Food and Drug Administration ("FDA") has authorized, 
and Somatogen and Lilly are currently performing, clinical trials 
in anesthetized surgical patients undergoing blood loss to gather 
efficacy/activity data and safety data in a large Phase II, multi-
site clinical trial.  See "Clinical Development Strategy" and 
"Government Regulation." Somatogen believes that Optro may offer 
a safe, effective and economically viable solution to the problems 
of red blood cell transfusion while avoiding the historical problems
of stroma-free hemoglobin because it:

     --   Eliminates the risk of infectious disease 
          transmission.  Because Optro is produced 
          recombinantly, it has no risk of transmission of
          human blood-borne infectious diseases such as AIDS
          and hepatitis.

     --   Offers universal compatibility regardless of blood 
          type.  Hemoglobin, unlike red blood cells, does not
          need to be typed and cross-matched.  As a result, 
          the Company believes that Optro will eliminate the 
          risk of potentially fatal post-transfusion 
          reactions due to errors in blood-type matching, and 
          that it may be used in situations where either time 
          does not permit cross-matching or it is not 
          possible to store numerous blood types.

















<PAGE>  9
SOMATOGEN, INC.

     --   Reduces dependence on blood from donors.  Because 
          Optro is produced through fermentation in E. coli, 
          its supply is not limited by the availability of 
          blood from the donor population.

     --   Provides longer shelf life.  Somatogen believes 
          that Optro will have a shelf life substantially 
          longer than the 35 to 42 days currently recommended
          for refrigerated red blood cells.  The Company is 
          conducting real time stability tests of Optro; the 
          Company has demonstrated a shelf life in excess of nine
          months at 4 degrees Celsius, and the Company believes 
          that the shelf life at 4 degrees Celsius may be 12 months
          or longer.

     --   Avoids the need for chemical modifications.  
          Somatogen has addressed the inherent limitations of 
          extracellular hemoglobin by synthesizing a 
          hemoglobin molecule that is very similar to human 
          hemoglobin but which has been genetically altered 
          to prevent the molecule from fragmenting in the 
          bloodstream.  By making these changes at the 
          genetic level, Somatogen avoids the need to modify 
          the hemoglobin molecule through chemical 
          processing.

     --   Improves oxygen-delivery capability.  Somatogen has 
          genetically engineered Optro in a manner which it 
          believes, based on animal studies, may release 
          oxygen to tissues in the body more effectively than 
          the hemoglobin contained in transfused red blood 
          cells.  Recent nuclear magnetic resonance 
          spectroscopy tests in animals to measure tissue
          high energy phosphates (and metabolic 
          intermediates) suggest that Optro is more effective 
          in delivering oxygen to tissue than red blood 
          cells.

Products in Development

     Somatogen is using its recombinant hemoglobin technology to 
develop products for a range of therapeutic and diagnostic 
applications.  These products include Optro, the Company's initial 
oxygen-carrying pharmaceutical.   The Company is currently 
performing expanded safety and efficacy studies of Optro in 
anesthetized surgical patients who are experiencing blood loss.

     The Company believes that rHb1.1, or other forms of genetically
engineered hemoglobin which the Company is currently pursuing might 
be useful in treating chronic anemia through its ability to stimulate 
red blood cell development (erythropoeisis).

     Listed below is a summary of the potential applications of the 
Company's recombinant human hemoglobin products currently in 
development:

     Acute Blood Replacement.  Optro, the potential oxygen-carrying 
therapeutic application of rHb1.1, has been initially targeted for use
as a replacement for acute blood loss in discrete clinical indications.

          Intraoperative Blood Replacement.  The Company 
     believes that Optro may be useful in the treatment of 
     blood loss that occurs in surgery.  Concern regarding 
     transmission of infectious diseases and other adverse 
     effects of giving donor blood has given rise to efforts
     to reduce or eliminate transfusions of donor blood 
     whenever practicable.  A number of techniques are 
     currently utilized to maximize the conservation of 
     blood, including autologous donation (self-donation), 
     intraoperative cell salvage, intraoperative hemodilution, 
     and use of various pharmacologic agents to reduce 
     intraoperative blood loss.  Notwithstanding these 
     efforts, over 2.5 million surgical patients are exposed 
     to blood transfusions with donated blood in the U.S. 
     each year.  Somatogen believes that Optro may play a 
     role in providing surgical patients with an alternative 
     to transfusion with donor blood.

















<PAGE> 11
SOMATOGEN, INC.

          Trauma.  Somatogen believes that Optro may also be 
     useful in the hospital emergency room and in settings 
     outside of the hospital environment because Optro does 
     not require typing or cross-matching, thereby 
     eliminating the time required to perform such functions 
     or the need to store multiple units of Type O blood 
     (which may be administered to anyone regardless of blood 
     type).  Initial recent results from animal studies 
     indicate that Optro is more efficacious than blood in 
     resuscitation from hypovolemia (a condition resulting 
     from extensive blood loss), a common problem often 
     associated with trauma. 

     Erythropoiesis/chronic anemia.  The Company believes that rHb1.1 
may have promise in stimulating the production of new red blood cells,
and that rHb1.1 may exert this effect by different mechanisms than 
existing therapeutics such as erythropoietin ("EPO").  rHb1.1 may also
serve as a source of iron in anemias where iron deficiency is important
(i.e., anemias unresponsive to EPO in patients with chronic renal 
failure). The Company has demonstrated hematopoietic activity of rHb1.1
in an animal model of induced anemia and in human hematopoietic tissues
in vitro.  Somatogen recently initiated Phase I clinical studies in 
patients with chronic renal failure and primary bone marrow cancer. 

Second Generation rHbs 

     Somatogen has constructed several different forms of recombinant 
hemoglobin that have been genetically engineered and, in some cases 
chemically modified to achieve enhanced attributes including extended 
circulating half-life.  The Company believes that such a modified 
recombinant hemoglobin may be useful in a number of applications 
requiring extended circulating half-life such as severe trauma and 
surgical procedures that involve extensive blood loss.  In addition, 
the Company believes that these molecules may be applicable in some 
of the applications identified above for Optro.  These molecules are 
currently in the research stage and early preclinical testing.

     The Company's products will require significant additional 
research and development, including extensive preclinical and clinical
testing, before the Company will be able to obtain FDA or foreign 
regulatory approval for any indication, if at all.  There can be no 
assurance that the Company's research and development efforts will be 















<PAGE> 12
SOMATOGEN, INC.

successful, that any of the Company's products under development, 
including Optro, will prove to be safe or effective in clinical trials, 
that the Company will be able to obtain FDA approval to sell any 
products, that any products can be manufactured at acceptable cost and 
with appropriate quality, or that any products, if and when approved, 
can be successfully marketed.

Clinical Development Strategy

   Oxygen Delivery Indications

     Somatogen is currently pursuing clinical development of Optro 
for intraoperative ("IO") blood replacement and acute normovolemic 
hemodilution ("ANH"). The clinical trials of Optro are being conducted
in three sequential phases (Phases I, II and III), although the phases
may overlap. The Phase I trials, which have been completed, gathered
data on safety (adverse effects) and dosage tolerance and preliminary
data on pharmacokinetics (clinical pharmacology). Following completion
of the Phase I trials, the Company reviewed the results of such trials
with the FDA, which authorized the Company to proceed to early Phase II
trials. The Company initiated these trials in the fall of 1994 in 
order to provide additional safety data, and to gather preliminary 
efficacy/activity information, in surgical patients undergoing blood 
loss. These trials were completed in September 1995. In these trials 
there have been no clinically significant, treatment-related adverse 
effects. In July 1996, Somatogen and Lilly commenced expanded Phase II
trials in surgical patients in order to gather additional safety 
information as well as more comprehensive efficacy/activity 
information. Following successful completion of the Phase II trials, 
Phase III trials would be undertaken to establish safety and efficacy 
in a larger population of surgical patients in order to provide the 
basis for the filing of a product license application with the FDA. 
In North America, the expanded Phase II and Phase III trials will be 
performed in conjunction with Lilly's clinical and research groups. 
Outside North America, Lilly will be responsible for clinical 
development of Optro except in Scandinavia where Pharmacia will be 
responsible for clinical development if necessary.




















<PAGE> 13
SOMATOGEN, INC.

     There can be no assurance that any of the clinical testing will 
be completed successfully within any specified time period, if at all,
with respect to Optro or any of the Company's products. There can also
 be no assurance that such testing will show Optro or any other product
to be safe or efficacious. Furthermore, the Company or the FDA may 
suspend clinical trials at any time if the subjects or patients 
participating in such trials are thought to be exposed to unacceptable
health risks. The Company is aware of four blood substitute products 
developed by other companies which began clinical trials that were 
subsequently halted due to safety concerns; all four of these 
companies have since announced that they have resumed clinical 
trials. Although the Company believes that its products are 
substantially different from these other blood substitute products, 
there can be no assurance that the Company will not encounter 
problems in clinical trials which will cause the Company or the 
FDA to suspend clinical trials or which will result in delays in 
the Company's clinical trials. See "Risk Factors -- Uncertainties 
Regarding Clinical Trials."

Late Phase II Clinical Trials

     In July 1996, the Company commenced patient enrollment in a 
multi-center, late Phase II study of the IO use of Optro to deliver 
oxygen and restore blood volume as a treatment for acute blood loss 
during surgery.  The study will examine the safety and efficacy of 
using 25 to 100 gram doses of Optro to replace one to four units of 
blood lost  by patients undergoing elective surgery.  The study will
enroll approximately 200 patients at 30 sites throughout the U.S. 
and Canada.

  Early Phase II Clinical Trials

     Intraoperative Blood Replacement: This single blinded, 
controlled trial was designed to study safety and to gather 
preliminary efficacy/activity data in patients who experience 
blood loss during surgery. This multi-center clinical trial 
involved 23 patients, of whom 16 received Optro at doses ranging 
up to 100 grams and seven patients received donated blood as a 
control. Six Optro patients received doses of 25 grams, four 
received doses of 50 grams, three received doses of 75 grams, and 
three received doses of 100 grams. The first three patients at the 
25 gram dose level were infused at a controlled rate, 















<PAGE> 14
SOMATOGEN, INC.

and all other patients were infused at a rate comparable to the rate of
infusion in blood transfusions. There were no clinically significant, 
treatment-related adverse events in this clinical trial. Patients in 
this trial received no prophylactic pre-treatment with any drugs to 
manage or avoid potential symptoms or side effects of Optro. None of
the patients in this study experienced the gastrointestinal symptoms
that had been seen in certain subjects in the Company's prior Phase I
clinical trials. In certain patients, there were transitory elevations
of amylase and lipase (pancreatic enzymes), which spontaneously 
resolved without treatment and which investigators determined not to 
be clinically significant.

     Acute Normovolemic Hemodilution: This single blinded, controlled 
study was designed to measure safety and to gather preliminary 
efficacy/activity data in patients who donate blood and receive Optro 
just prior to surgery, at doses ranging up to 50 grams. Ten patients 
were dosed, of whom seven received Optro and three received saline as 
a control. Three patients received 12.5 grams, one patient received 25
grams and three patients received 50 grams of Optro. Patients in this 
trial received no prophylactic pre-treatment with any drugs to manage 
or avoid potential symptoms or side effects of Optro. There were no 
clinically significant, treatment-related adverse events, and no 
gastrointestinal symptoms in any of the patients in this study. As in 
the IO trial, certain patients experienced transitory elevations of 
amylase and lipase levels, which spontaneously resolved without 
treatment and which investigators determined not to be clinically 
significant.

  Phase I and Phase I/II Clinical Trials

     From 1991 through 1994, the Company conducted a series of safety
trials of Optro, initially in normal volunteers (Phase I) and later 
in surgical patients (Phase I/II). These trials involved an aggregate
of 120 subjects and patients, of whom 99 received Optro and 21 received
control solutions. The maximum dose in these safety trials was 25 
grams.

     In the course of the trials, certain subjects experienced 
transitory mild to moderate symptoms, including certain 
gastrointestinal symptoms. The Company instituted manufacturing 
process changes which reduced the incidence of certain symptoms, 
and used several common pharmacologic agents as appropriate to 
prevent or manage these symptoms.

Chronic Anemia Indication

     The Company has initiated Phase I trials of its recombinant 
hemoglobin, rHb1.1, as an agent for stimulating red blood cell 
formation (hematopoiesis).   The first study was initiated in June 
1996 and  will evaluate the safety and hematopoietic activity of 
repeated low doses of rHb1.1 in approximately 50 patients with 
anemia resulting from end stage renal disease.  The randomized, 
double-blind, placebo-controlled trial is a dose-ranging study 
being conducted at five sites within the U.S.  Participants in 
the trial will have been on hemodialysis for six months or more, 
and will have responded to treatment with exogenous erythopoietin.

     The Company plans to initiate a second Phase I trial.  The trial 
is expected to evaluate the safety and hematopoietic activity of 
repeated low doses of rHb1.1 in approximately 20 patients with chronic 
anemia due to primary bone marrow failure and malignancy.  This 
randomized, open-label dose-ranging study is being conducted at one 
site in the U.S.

Research and Development

     Somatogen's research and development efforts are focused on 
clinical trials of Optro, process development and new product
development.  In the process development area, Somatogen is working 
on improving all phases of its existing pilot manufacturing processes 
in order to allow economical commercial scale production.  Somatogen 
is also developing recombinant hemoglobin products for additional 
applications.

     In fiscal 1996, 1995 and 1994, net research and development 
expenses were $16,949,000, $14,968,000 and $18,029,000, respectively.
Somatogen expects these expenses to increase during the foreseeable 
future.

Manufacturing

     The Company's ability to operate profitably will depend on the 
manufacturing of recombinant hemoglobin products in very large 
quantities and at a competitive cost, while consistently achieving 
appropriate levels of product purity. To date, Somatogen has 
manufactured its initial product in a pilot facility and only in 
limited quantities. To successfully establish commercial manufacturing
capacity, improvements must be made in enhancing manufacturing 
processes, scaling up such processes, reducing product costs and 
demonstrating the consistent manufacture of a clinically safe product.
The Company's alliance with Lilly will provide additional resources 
and expertise to assist in achieving these development goals. The 
implementation and testing of process improvements in the Company's 
pilot production facility may affect the production schedule for 
clinical material, which may in turn affect the rate of progress in 
clinical trials for Optro. Somatogen has devoted substantial resources
to developing an efficient production process capable of producing 
recombinant hemoglobin. Somatogen has genetically engineered 
recombinant hemoglobin to overcome certain of the inherent limitations
of naturally occurring hemoglobin. By addressing these limitations at 
the genetic level, Somatogen has avoided the need to modify the 
hemoglobin molecule through chemical processing.

     Optro is produced through a fermentation process as a stable, 
fully functional, properly folded, soluble intracellular protein. 
Optro is produced by introducing the alpha and beta globin genes for
Optro into a host cell (E. coli), growing large quantities of the 
genetically engineered host cells, breaking open the cells to 
remove the hemoglobin, and purifying the hemoglobin. In order to 
function properly, the globin chains must be properly folded. 
Additionally, four heme groups must be properly incorporated into 
the molecule. Somatogen's proprietary technology enables it to produce
the entire hemoglobin molecule in E. coli without the need for any 
subsequent steps to correctly assemble the molecule. The Company has 
also developed proprietary purification techniques for Optro using 
standard column chromatography and conventional large scale processing
equipment.



















<PAGE> 17
SOMATOGEN, INC.

    Somatogen constructed and is operating a pilot production 
facility consisting of approximately 24,000 square feet. The Company's
pilot manufacturing facility includes a 600 and 1,500 liter fermentor 
for production of Optro. The pilot manufacturing facility includes the
equipment necessary to produce hemoglobin in E. coli, to separate the 
hemoglobin from the cells and to purify the hemoglobin. This facility 
has been producing Optro since December 1990 and is anticipated to 
have sufficient capacity to meet clinical needs for Phase II clinical
trials.

     Under the terms of the Company's collaboration with Lilly, Lilly
will assume responsibility for producing material for the Company's 
Phase III trials as well as commercial production thus eliminating 
the need for Somatogen to build commercial scale manufacturing 
facilities for Optro at an estimated cost of more than $150,000,000.
Such material is anticipated to be produced at an existing Lilly 
facility in the United Kingdom, which will require significant 
modifications. Moreover, Lilly, as the Company's manufacturing 
partner, must adhere to cGMP regulations and to guidelines enforced 
by the FDA and other regulatory agencies through their facilities 
inspection programs. A delay in the completion of modifications to 
such facilities or the need to modify such facilities to continue 
to comply with FDA and other regulatory agency rules could delay 
Somatogen's ability to complete its clinical trials and to seek 
regulatory approvals for the sale of Optro. To the extent the 
Company has manufacturing requirements for non-oxygen carrying 
indications of rHb1.1, or other products outside the Lilly 
Alliance, the Company may need to develop additional manufacturing
facilities.

     The manufacturing process for Optro requires substantial 
amounts of water and other raw materials. Although these raw 
materials are currently available in quantities sufficient to meet 
the Company's current needs, there can be no assurance that these 
raw materials will be available in sufficient quantities to meet 
the needs for commercial production at an acceptable cost, or that 
regulatory agencies will approve the use of these raw materials. 
If the Company or Lilly were to experience raw material shortages, 
such shortages could affect its ability to produce products.


















<PAGE> 18
SOMATOGEN, INC.

     In order to manufacture Optro at a commercial scale at an 
acceptable cost, Somatogen and Lilly must make further improvements 
in certain existing process technologies, and complete adaptation of 
these technologies for use at a large scale. This work is focused on 
reducing product cost, improving current expression levels, improving 
recovery of recombinant hemoglobin following fermentation, enhancing 
purification yields through use of improved techniques and materials, 
and increasing product stability. Somatogen believes that developing a 
cost-effective manufacturing process for commercial scale production 
of Optro with a consistently high level of purity will require 
improvements to some phases of its existing pilot manufacturing 
processes, but should not require any fundamental technological 
breakthroughs. While many of these improvements have now been 
demonstrated at 6,000 liter scale, there can be no assurance that 
the Company will be able to successfully implement any of these 
improvements as scale-up of the process to commercial levels (50,000 
liter) proceeds. The Company's products will be given in large 
dosages. They must be rigorously purified since impurities may lead 
to serious and potentially fatal toxic reactions. The Company must 
also develop extremely sensitive analytical techniques to show that 
it has achieved acceptable levels of purity. There can be no 
assurance that the Company will be able to achieve or maintain 
an appropriate level of product purity or that it can develop assays
 that are sufficiently sensitive to demonstrate the required high 
level of purity. As part of its clinical development program, the 
Company has made process improvements to reduce or eliminate certain 
side effects. The time required to implement some of these improvements
has resulted in extending the length of the clinical trials. There can 
also be no assurance that process changes will not require clinical 
studies which would require additional expenditures and may cause 
delays in the clinical development of Optro.

     The Company's agreement with Lilly provides that Lilly has 
certain rights to terminate the agreement. There can be no assurance 
that the collaboration will continue and result in successful 
commercialization of Optro. If the Lilly collaboration were 
discontinued, Somatogen would be required to seek other alternatives 
for further manufacturing, clinical development and marketing 
activities.  There can be no assurance that Somatogen would be able 
to develop acceptable alternatives in a timely manner in the event 
that the Lilly Alliance were to be discontinued.

Sales and Marketing

     Because the initial target market for Optro is replacement of 
blood lost in surgery, Somatogen and Lilly will focus their marketing 
and selling efforts on key operating room personnel, including 
anesthesiologists and surgeons. The Company's strategic alliance with 
Lilly contemplates that Lilly will be responsible for marketing, 
sales and distribution of Optro in all markets outside of North 
America. The alliance also contemplates that the Company and Lilly 
will jointly market and sell Optro in North America, while Lilly 
will assume sole responsibility for distribution. The Company is 
required to contribute to the total selling effort in North America 
in order to maintain a profit sharing relationship. Given the fact 
that the customers are highly concentrated in the hospital setting,
the Company and Lilly believes they can achieve optimal sales coverage 
in North America with a relatively small specialized sales force. 
There can be no assurance that the Company will be able to build 
such a sales force for Optro or any other potential products or 
that its sales and marketing efforts will be successful.

     There can be no assurance that Somatogen or its partners will
receive the necessary governmental approvals to market and distribute
Optro in any country.

     Somatogen may enter into additional strategic alliances with 
Lilly or other companies to develop and promote products for 
erythropoiesis/anemia and other non-oxygen carrying indications.

Patents and Trade Secrets

     Proprietary protection for the Company's products, processes 
and know-how is important to Somatogen's business. The Company's 
policy is to file patent applications to protect technology, 
inventions and improvements that are considered important to the 
development of its business. The Company also relies upon trade 
secrets, know-how, continuing technological innovation and licensing 
opportunities to develop and maintain its competitive position.

     The Company seeks patent protection for its proprietary 
technology and products in the United States and in foreign countries.
The Company's products and inventions may involve both synthetic 
compounds that are not naturally occurring and synthetic forms of 















<PAGE> 20
SOMATOGEN, INC.


naturally occurring molecules. To the extent that the Company's 
products or inventions are synthetic chemical compounds that are 
not natural products, they may, provided standard patentability 
criteria are met, be afforded patent protection under well settled 
principles and procedures established by the U.S. and other patent 
offices. To the extent Somatogen's products or inventions are 
synthetic forms of naturally occurring molecules, the extent and 
nature of the protection available is less certain.

     The Company's patents include claims for certain hemoglobin 
compositions and for the methods of use of certain hemoglobin 
compositions as a blood substitute. The Company has filed or 
licensed patent applications in the U.S. and in certain other 
countries seeking protection for recombinant hemoglobin technology 
and compounds developed by the Company and/or the Medical Research 
Council ("MRC"). In July 1991, the Company's initial U.S. patent 
was issued covering blood substitute products based upon hemoglobin 
that has been genetically engineered to improve its ability to 
deliver oxygen to the tissues. This patent will expire in the year 
2008. Similar patents have been issued jointly to the Company and 
the MRC in the United Kingdom (expiring in 2007) and Australia 
(expiring in 2004). A European patent containing certain related 
claims has also been granted, but is being opposed by another 
company. Somatogen has entered into an agreement with the MRC, 
which grants the Company the exclusive right to make, use and sell 
products covered by such U.S. and U.K. patents and certain additional 
foreign counterparts. The Company has agreed to pay the MRC a royalty 
on net sales in certain countries of artificial hemoglobin products 
using the MRC know-how or covered by an MRC patent for a period of 
15 years from the date of agreement. Patents covering methods of 
expressing and genetically stabilizing hemoglobin have been issued 
to the Company in Australia, South Africa and New Zealand. A patent 
covering non-naturally occurring disulfide-stabilized hemoglobin has 
also been issued in the U.S. (expiring in 2008). The remaining 
hemoglobin-related patent applications owned, co-owned or licensed 
by the Company are pending.




















<PAGE> 21
SOMATOGEN, INC.

     The patent positions of biotechnology firms, including 
Somatogen, are generally uncertain and involve complex legal and 
factual questions. Consequently, the Company does not know whether 
any of its pending applications will result in the issuance of any 
patents or whether any issued patents will provide significant 
proprietary protection or will be circumvented or invalidated. 
Since patent applications in the U.S. are maintained in secrecy 
until patents issue and publication of discoveries in the scientific 
or patent literature tend to lag behind actual discoveries by several 
months, Somatogen cannot be certain that it was the first creator of 
inventions covered by pending patent applications or that it was the 
first to file patent applications for such inventions. The Company 
is aware of certain U.S. patents owned by other parties who may 
claim infringement by certain products or processes contemplated by 
the Company. The Company believes that certain of such patents may 
be invalid. The Company believes that licenses would be available 
for other patents, that the Company's contemplated products, 
processes or methods could be used in a manner that would avoid 
infringement, could be modified to avoid infringement, or are not 
material to the Company's business. There can, however, be no 
assurance that  licenses would be available on terms acceptable to 
the Company, or its partners, or at all. If the Company cannot 
obtain such licenses and cannot show such unlicensed patents to 
be invalid or unenforceable, the Company could encounter delays 
in product market introductions and incur substantial additional 
costs while it attempts to design around such intellectual property 
rights, or it could be prevented from the development, manufacture 
or sale of products requiring such licenses. There also can be no 
assurance that any modifications effected by the Company in an effort
to avoid infringement of certain patents would be successful or would 
not result in infringement of other patents. Moreover, there can be 
no assurance that all U.S. patents that may pose a risk of 
infringement have been identified. Additionally, the Company has 
not sought to identify foreign patent applications or patents 
which might affect its future foreign sales or operations. The 
Company could incur substantial costs in defending against suits 
brought against it on such U.S. or foreign intellectual property 
rights or prosecuting suits which the Company 



















<PAGE> 22
SOMATOGEN, INC.

brings against other parties to protect its intellectual property 
rights. Competitors or potential competitors may have filed 
applications for, or have received patents and may obtain additional 
patents and proprietary rights relating to, compounds or processes 
competitive with those of the Company. The Company has not reached a 
final decision as to all details of its manufacturing process, and 
modifications to that process may increase the patent infringement 
risks faced by the Company.

     The Company also relies upon unpatented trade secrets, and there 
can be no assurance that others will not independently develop 
substantially equivalent proprietary information and techniques, or 
otherwise gain access to the Company's trade secrets or disclose such 
technology, or that the Company can meaningfully protect its rights to 
its unpatented trade secrets. Somatogen requires each of its employees,
consultants and advisors to execute a confidentiality agreement upon 
the commencement of an employment or consulting relationship with the 
Company. There can be no assurance, however, that these agreements will
provide meaningful protection for the Company's trade secrets in the 
event of unauthorized use or disclosure of such information.

Competing Technologies

     Problems associated with the transfusion of human donor blood 
have stimulated numerous efforts to reduce transfusion with donated 
blood. Most efforts to develop a blood substitute have concentrated 
on developing stroma-free hemoglobin from human or bovine red blood 
cells. Stroma-free hemoglobin must be rigorously purified to remove 
all of the non-hemoglobin elements of the red blood cell to avoid 
potentially severe reactions resulting from the contaminating elements.
In addition, stroma-free hemoglobin must be chemically modified in order
to prevent dissociation into dimers which can be toxic to the kidneys.
Hemoglobin derived from human red blood cells must also be chemically 
modified to reduce its oxygen affinity.























<PAGE> 23
SOMATOGEN, INC.



     The use of stroma-free hemoglobin suffers from certain inherent 
limitations. Hemoglobin that is obtained from human blood may carry a 
risk of transmission of blood-borne infectious disease. The 
technologies for inactivating viral agents in human blood are rather 
limited and unproven at present. In addition, the supply of human-
derived hemoglobin is dependent on the availability of human donor 
blood. Today, there is not a ready supply of excess human blood. An 
alternative approach to the supply problem associated with human-
derived hemoglobin is to derive products from plants or animals that 
have been genetically engineered to produce human hemoglobin 
(transgenic plants or animals). However, Somatogen believes that the 
transgenic production of hemoglobin may have a number of limitations, 
including many of the same limitations as stroma-free hemoglobin. At 
least four other companies have announced that they have commenced 
human clinical trials of hemoglobin-based oxygen carrying solutions.  
One of these companies, Baxter International Inc., has announced that 
they have received FDA approval to commence two pivotal phase III 
studies with their human derived hemoglobin solution.

     Several of the Company's competitors are currently developing 
products derived from bovine hemoglobin, which has a molecular 
structure that is different from human hemoglobin. One of the Company's
competitors is attempting to modify bovine-derived hemoglobin by 
attaching polyethylene glycol molecules in an effort to mask the 
differences between bovine and human hemoglobin from the human immune 
system. Just as hemoglobin sourced from human red cells carries a risk 
of blood-borne disease transmission, hemoglobin sourced from animal red
blood cells may also transmit blood-borne disease.

     Certain other non-hemoglobin molecules have also been explored as 
blood substitutes. PFCs, inert chemicals which are capable of 
dissolving and transporting oxygen, have been studied most extensively.
PFCs are synthetically produced thereby eliminating the risk of 
transmission of infectious diseases, can transport large amounts of 
oxygen, and have no antigenicity thereby eliminating the need for 
blood-typing and cross-matching. The Company is aware that two of its 
potential competitors have commenced human trials for the use of a PFC-
based product as a blood substitute.

















<PAGE> 24
SOMATOGEN, INC.



     The mechanism of oxygen transport by PFC compounds is very 
different from hemoglobin or blood. Oxygen is physically dissolved 
into PFC emulsions, with no specific bonding interaction with the 
perfluorocarbon molecules. Thus, a linear increase in available 
oxygen results in a linear increase in the amount of oxygen dissolved 
in the PFC carrier, in contrast to the sigmoidal oxygen saturation-
dissociation curve for hemoglobin. Consequently, PFCs require very 
high oxygen levels in the lung in order for them to dissolve 
physiologically meaningful amounts of oxygen. To achieve these high 
levels of oxygen, patients must be ventilated with very high levels 
of oxygen. Current anesthesia practice does not utilize high oxygen 
inspiration during surgery, and in many situations it is considered 
dangerous.

Competition

     Optro will compete directly with red blood cells for volume 
expansion and oxygen delivery applications and with other solutions 
for volume expansion applications. Additionally, Optro may supply 
clinical utility in specific clinical situations where the use of 
red blood cells is not necessary. There can be no assurance that 
Optro or any other product of Somatogen will have advantages which 
will be significant enough to cause medical professionals to adopt 
its use rather than to continue to use established therapies. The 
pricing of Somatogen's products in relation to established therapies 
could also affect market acceptance of such products. Somatogen 
believes, however, that Optro will compete on the basis of quality 
because it may offer a safe and cost-effective solution to the 
problems of red blood cell transfusions, while avoiding the problems 
of stroma-free hemoglobin. See "Somatogen's Recombinant Hemoglobin 
Technology."

     Competition in the pharmaceutical industry is intense. There 
are many pharmaceutical companies, biotechnology companies, public 
and private universities and research organizations actively engaged
in research and development of blood substitute products. Many of the
Company's existing or potential competitors have substantially 
greater financial, technical and human resources than the Company 
and may be better equipped to develop, manufacture and market 
products. 















<PAGE> 25
SOMATOGEN, INC.

In addition, many of these companies have extensive experience in 
preclinical testing and human clinical trials. These companies may 
develop and introduce products and processes competitive with or 
superior to those of the Company. Companies pursuing several competing 
technologies have entered or are expected to enter clinical trials for 
their products. There can be no assurance that the Company will be able
to compete successfully.

Government Regulation

     Regulation by governmental authorities in the United States and 
foreign countries will significantly affect the Company's and Lilly's 
ability to manufacture and market the Company's products and to 
conduct the Company's ongoing research and product development 
activities. All of Somatogen's current and anticipated future 
products will require regulatory approval by appropriate government 
agencies before those products can be commercialized. Human 
therapeutic products are subject to rigorous preclinical and 
clinical testing and other approval procedures by the FDA and 
similar health authorities in foreign countries. Various federal, 
state and foreign statutes also govern or influence the manufacture, 
safety, labeling, storage, record keeping and marketing of such 
products. The process of obtaining these approvals is costly and 
time-consuming. Moreover, ongoing compliance with these requirements 
can require the expenditure of substantial resources. Any failure by 
the Company or Lilly or other collaborators or licensees to obtain, 
or any delay in obtaining, required regulatory approvals would 
adversely affect the marketing of the Company's products and its 
ability to derive product or royalty revenue.

     Preclinical testing is generally conducted in animal or in 
vitro models to evaluate the potential efficacy and safety of a 
compound before it is administered to humans. The results of these 
studies are submitted to the FDA as part of an Investigational New 
Drug Application ("IND"), which must be reviewed before human 
clinical testing can begin. The Company's preclinical studies for 
the initial indications for Optro described in the Company's first 
IND were completed in April 1991, and such studies did not show 
any significant toxic effect of Optro. These studies were performed 
in part by an independent preclinical testing lab, and the protocols
were designed in consultation with the FDA.
















<PAGE> 26
SOMATOGEN, INC.


     Clinical trials involve the administration of the investigational 
new drug to healthy subjects and to patients, under the supervision of 
a qualified principal investigator. Clinical trials are conducted 
under protocols that detail the objectives of the study, the 
parameters to be used to monitor safety and the efficacy/activity 
criteria to be evaluated. Each protocol and subsequent amendments 
must be submitted to the FDA. In addition, each clinical study must 
be conducted in accordance with "Good Clinical Practices" as 
prescribed by the FDA. Each clinical study is conducted under the 
auspices of an independent Institutional Review Board ("IRB") at 
the institution at which the study will be conducted. The IRB will 
consider, among other things, ethical factors, the safety of human 
subjects and patients, and the possible liability of the institution.

     Following completion of the Company's Phase I clinical trials, 
the Company reviewed the results of such trials with the FDA, which 
authorized the Company to proceed to early Phase II trials in 
surgical patients undergoing blood loss. The Company initiated 
these trials in the fall of 1994. See "Clinical Development 
Strategy." There can be no assurance that clinical testing will 
be completed successfully within any specified time period, if at 
all, with respect to any of the Company's products subject to such 
testing. Furthermore, the Company or the FDA may suspend clinical 
trials at any time if it is felt that the subjects or patients are 
being exposed to an unacceptable health risk. The Company is aware 
of four blood substitute products developed by other companies which 
began clinical trials that were subsequently halted due to safety 
concerns; all four of these companies have since announced that they 
have resumed and are continuing clinical trials. Although the Company 
believes that its products are substantially different from other 
blood substitute products, there can be no assurance that the Company 
will not encounter problems in clinical trials which will cause the 
Company to delay or suspend clinical trials.























<PAGE> 27
SOMATOGEN, INC.

     In the case of biologic products such as the Company's 
recombinant hemoglobin, the results of pharmaceutical development 
and the preclinical and clinical testing are submitted to the FDA 
in the form of a product license application ("PLA"), and the 
results, data and facility description are submitted to the FDA in
the form of an establishment license application ("ELA").  Under 
user fee legislation the ELA must be submitted within six months 
under standard review and three months under expedited review.  The 
PLA and ELA must be approved before commercial sales may begin. The 
FDA may respond to the PLA and ELA by granting a product license, 
or by denying the applications if it finds that the applications do 
not meet the criteria for regulatory approval. 

The FDA also may respond by requiring the Company to perform 
additional testing or supply additional information. Notwithstanding 
the submission of such data, the FDA may ultimately decide that the 
applications do not satisfy its regulatory criteria for licensing. 
The testing and approval process is likely to require substantial 
time and effort. There can be no assurance that approval will be 
granted for any of Somatogen's products on a timely basis, if at 
all. Somatogen has made and must continue to make substantial 
financial commitments in order to prove safety and efficacy/
activity of Optro in humans to receive FDA approval of Optro.

     In addition to regulations enforced by the FDA, the Company 
also may be subject to regulation under the Occupational Safety 
and Health Act, the Environmental Protection Act, the Toxic 
Substances Control Act, the Resource Conservation and Recovery 
Act, the Comprehensive Environmental Response, the Compensation 
and Liability Act, the National Environmental Policy Act, the 
Clean Air Act, the Medical Waste Tracking Act, the federal Water 
Pollution Control Act and other present and potential future 
federal, state or local regulations. See "Manufacturing."
























<PAGE> 28
SOMATOGEN, INC.


     The regulatory process, which includes preclinical and clinical 
testing of each product to establish its safety and efficacy and post-
marketing studies, can take many years and requires the expenditure 
of substantial resources. Data obtained from preclinical and clinical 
activities are susceptible to varying interpretations which could 
delay, limit or prevent FDA regulatory approval. In addition, delays 
or rejections may be encountered based upon changes in FDA policy 
during the period of product development and FDA regulatory review 
of each submitted new product license application. Similar delays may 
also be encountered in foreign countries. Each manufacturing facility 
for a biologic product, such as Optro, must also be licensed by the 
FDA. There can be no assurance that even after such time and 
expenditures, regulatory approval will be obtained for any products 
developed by Somatogen or any manufacturing facility intended to 
produce such products by the Company or Lilly. Moreover, if 
regulatory approval of a product is granted, such approval may 
entail limitations on the indicated uses for which it may be
 marketed. Further, even if such regulatory approval is obtained, 
a marketed product, manufacturer and manufacturing facilities are 
subject to continual review and periodic inspections, and later 
discovery of previously unknown problems with a product, manufacturer 
or facility may result in restrictions on such product or 
manufacturer, including withdrawal of the product from the market. 
Failure to comply with the applicable regulatory requirements 
can, among other things, result in fines, suspension of regulatory 
approvals, product recalls, operating restrictions and criminal 
prosecution. Further, additional governmental regulation may be 
established which could prevent or delay regulatory approval of the 
Company's products.

Reimbursement

     Somatogen's ability to successfully commercialize its products 
will depend in part on the extent to which reimbursement of the cost of 
such products and related treatment will be available from government 
health administration authorities, private health insurers and other 
organizations.  Third-party payors are increasingly challenging the price
of medical products and services. Significant uncertainty exists 
as to the reimbursement status of newly approved health care products, 
and there can be no assurance that adequate third-party coverage will 
be available to enable Somatogen to maintain price levels sufficient 
for realization of an appropriate return on its investment in product 
development.  The public and the federal government have recently 
focused significant attention on reforming the health care system in 
the U.S. A number of health care reform measures have been suggested, 
including price controls on therapeutics.  Public discussion of such 
measures is likely to continue, and concerns about the potential 
effects on different possible proposals have been reflected in the 
volatility of the stock prices for companies in health care and related 
industries.  Although the Company cannot predict which, if any, of such 
reform proposals will be adopted, when they may be adopted or what 
impact they may have on the Company, adoption of certain of the 
proposals could have a material adverse effect on the Company and its 
business and could cause volatility in the market price of the 
Company's stock.

Human Resources

     As of July 31, 1996 Somatogen employed 200 individuals, of whom 
approximately 56 hold Ph.D., M.D. or other advanced degrees.  Of its 
total work force, 83 employees are dedicated to manufacturing, 65 
are engaged in research and development activities and 52 are devoted
to support and administrative activities.  A significant number of 
the Company's management and professional employees have had prior 
experience with pharmaceutical, biotechnology or medical products 
companies.  Somatogen believes that it has been successful in 
attracting skilled and experienced scientific personnel and that 
it maintains good relations with its employees. The Company's 
success will depend in large part upon its ability to attract and 
retain these and future employees.  The Company faces competition 
in this regard from other companies, research and academic 
institutions and government entities.















<PAGE> 30
SOMATOGEN, INC.


     Somatogen's success is highly dependent on the continued services
of a limited number of skilled managers and scientists.  The loss of 
any of these individuals could have a material adverse effect on the 
Company.  In addition, the success of the Company will depend upon, 
among other factors, successful recruitment and retention of additional
highly skilled and experienced management and technical personnel.  
There can be no assurance that the Company will be able to retain 
existing employees, or find, attract or retain additional personnel 
on acceptable terms given the competition among numerous pharmaceutical
and health care companies, universities and non-profit research 
institutions of such personnel.

     Somatogen's anticipated growth and expansion into areas and 
activities requiring additional expertise, such as clinical testing, 
government approval, manufacturing, sales and marketing, are expected 
to place increased demands on the Company's resources.  These demands 
are expected to require the addition of new management personnel and 
the development of additional expertise by existing management 
personnel.  The failure to acquire such services or to develop such 
expertise will adversely affect prospects for the Company's success.

comprise approximately 76,900 square feet located in Boulder, 
Colorado.  The Company's laboratories are equipped for research 
activities in biochemistry, analytical chemistry and synthetic 
chemistry.  The leases covering these facilities expire beginning 
in February 1997.  The Company anticipates that its current 
facilities will meet the Company's research and development 
needs through fiscal 1997.

     The Company has a pilot manufacturing facility consisting 
of approximately 24,000 square feet.  The Company's lease covering 
this facility expires in October 1997.   

     In September 1992, the Company began construction  of a 
clinical manufacturing facility ("CMF-1"), which was designed 
to expand the Company's capacity to produce Optro for U.S. and 
international clinical trials, as well as support initial 
commercial production.  After entering into the Lilly Alliance, 
the Company reevaluated its manufacturing facility requirements,
 cancelled construction of the CMF-1 facility and recorded a 
charge of approximately $29 million in fiscal 1994.  The land, 
building and related equipment of CMF-1 and land intended for 
construction of a  larger commercial manufacturing facility 
are being held for sale.

Item 3.  Legal Proceedings
- ------
     In December 1991, a warrantholder, with warrants to purchase 
an aggregate of 1,112 shares of Common Stock at a weighted average 
exercise price of $46.51 per share, filed a complaint in the 
District Court for the City and County of Denver, Colorado, James 
McCabe v. Somatogen, Inc., Charles H. Scoggin and James C.T. 
Linfield, apparently claiming, among other things, that he is 
entitled to warrants to purchase one-half of one percent of the 
number of shares of the Company's Common Stock outstanding as of 
an unspecified date for an aggregate exercise price of $59,512.  
The trial court granted summary judgment in favor of the Company 
in May 1994 on all claims.  The grant of summary judgment was 
sustained in June 1996 by the Colorado Court of Appeals, and the 
Colorado Supreme Court has declined to hear the warrantholder's 
appeal.  

     In October 1994, three other warrantholders with warrants 
to purchase an aggregate of 2,375 shares of Common Stock at a 
weighted average exercise price of $60 per share, filed a complaint 
in the District Court of the City and County of Denver, Colorado, 
Kenneth D. Anderson, et al. v. Somatogen, Inc. asserting claims 
similar to those asserted by James McCabe.  In July 1995, the 
trial court granted summary judgment in favor of the Company on 
all claims.  The warrantholders have appealed the grant of summary 
judgment.  The Colorado Court of Appeals has not yet rendered a 
decision on such appeal.  The Company believes that the 
warrantholders claims in the foregoing proceedings are without 
merit and that the outcome of the litigation will not have a 
material effect on the Company's capital structure or financial 
position.

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


     Except for the historical information contained herein, the 
following discussion contains forward-looking statements that 
involve risks and uncertainties.  The Company's actual results 
could differ materially from those discussed here.  Factors that 
could cause or contribute to such differences include, but are 
not limited to, those discussed in this section and elsewhere in 
this Form 10-K.  

     Since 1987, Somatogen has been a development stage company and 
has devoted substantially all of its efforts and resources to 
research and development related to its recombinant hemoglobin 
technology.  The Company has been unprofitable to date and expects 
to incur substantial and increasing operating losses for the next 
several years due to continued requirements for product and process 
research and development, preclinical and clinical testing, 
regulatory activities and establishment of a sales and marketing 
organization. For the period from its inception to June 30, 1996, 
the Company incurred a cumulative net loss of $136,955,000.  The 
amount of future net losses and the time required by the Company 
to achieve profitability are highly uncertain.  There can be no 
assurance that the Company will be able to achieve profitability 
at all or on a sustained basis.   

     In June 1994, the Company entered into the Lilly Alliance 
whereby Lilly is co-developing Somatogen's lead human hemoglobin 
product, Optro and in September 1995, Somatogen and Lilly agreed 
to amend certain terms of the Lilly Alliance.  Somatogen and Lilly
 share certain development costs of Optro.  Lilly has responsibility 
for commercial-scale manufacture of the product and will have 
exclusive marketing rights worldwide, except in North America and 
Scandinavia.  Lilly and Somatogen will co-promote Optro in North 
America.  Lilly will pay a royalty to the Company on sales of Optro 
outside North America (except in Scandinavia, where Pharmacia has 
the right to market Optro).

Results of Operations

     Fiscal year ended June 30, 1996 ("fiscal 1996") as compared to 
the fiscal years ended   June 30, 1995 ("fiscal 1995") and June 30, 
1994 ("fiscal 1994"):

SOMATOGEN, INC.


Revenue

     The Company had no revenue for fiscal 1996 and 1995.  The 
Company had revenue of $11,000 for fiscal 1994.  Fiscal 1994 
revenue was derived primarily from a cost plus fixed fee 
government contract with the U.S. Navy which expired in September 
1993 and research and development grants.

Operating Expenses

     For fiscal 1996, total operating expenses increased 10% to 
$21,099,000 from $19,250,000 for fiscal 1995, due to increased 
research and development efforts as further described herein.  

     For fiscal 1995, total operating expenses decreased to 
$19,250,000 from $51,422,000 for fiscal 1994.  Fiscal 1994 
operating expenses included a $29,194,000 non-recurring charge 
related to the writedown of manufacturing assets.  Excluding the 
non-recurring charge, total operating expenses decreased 13% from 
$22,228,000 in fiscal 1994, primarily due to the sharing of Optro 
development costs with Lilly.  

     Net research and development expense for fiscal 1996 increased 
by 13% to $16,949,000 from $14,968,000 in fiscal 1995.  For fiscal 
1995, net research and development expenses decreased by 17% from 
$18,029,000 in fiscal 1994.

     Excluding Lilly reimbursements, research and development 
expense for fiscal 1996 increased by 5% to $19,849,000 from 
$18,890,000 for fiscal 1995.  For fiscal 1995, research and 
development expense increased by 5% from $18,029,000 in fiscal 
1994.  These increases are primarily a result of increased 
expenditures related to product and process development, 
including preclinical trials.  

     Reimbursements from Lilly aggregated $6,150,000 and $4,022,000
in fiscal 1996 and 1995, respectively.  There were no reimbursements
from Lilly in fiscal 1994.  The increase in the reimbursements from 
Lilly is primarily a result of increased reimbursable clinical 
development expenditures and from the September 1995 amendment to 
the Lilly Alliance which provided that, effective January 1, 1996, 
certain process development expenditures would be reimbursable.

SOMATOGEN, INC.


     Reimbursements to Lilly aggregated $3,250,000 and $100,000 in 
fiscal years 1996 and 1995, respectively.  There were no reimbursements
to Lilly in fiscal 1994.  The increase in reimbursements to Lilly 
results from the sharing of clinical development costs and from 
sharing process development costs which began January 1, 1996 
pursuant to the September 1995 amendment to the Lilly Alliance.  

     Reimbursements attributable to the Lilly Alliance may vary 
significantly from quarter to quarter and year to year.

     General, administrative and marketing expenses for fiscal 1996 
of $4,150,000 decreased $132,000 or 3% compared to fiscal 1995.  
For fiscal 1995, general, administrative and marketing expenses 
of $4,282,000 increased $83,000 or 2% compared to fiscal 1994.

     The Company incurred a non-recurring charge, which was 
principally non-cash, for the year ended June 30, 1994 associated 
with the writedown of its clinical manufacturing assets of 
$29,194,000.

Interest Income and Other, Net.

     For fiscal 1996, net interest income and other increased 
$930,000, or 43% to $3,076,000.  The increase is the result of 
interest earned from higher average cash and investment balances 
and decreased interest expense resulting from lower debt and 
capital lease balances.

     For fiscal 1995, net interest income and other increased 
203% to $2,146,000 from $708,000 in fiscal 1994.  The increase 
is the result of higher average cash and investment balances, 
lower debt and capital lease balances and higher yields on U.S.
 government securities, commercial paper and money market funds 
held by the Company.

Taxes

     The Company incurred losses for federal income tax purposes 
in fiscal 1996, 1995 and 1994 and therefore incurred no tax 
liability or expense for any of those years.
















<PAGE> 42
SOMATOGEN, INC.



     At June 30, 1996, the Company had net operating loss 
carryforwards for federal income tax purposes of approximately 
$109,000,000.  Under the federal income tax laws, approximately 
$3,000,000 of these loss carryforwards cannot be utilized due to 
prior changes in stock ownership.  The remainder of the loss 
carryforwards will expire in the years 2003 through 2011.  
Future changes in stock ownership could result in a further 
limitation on the utilization of present and future loss 
carryforwards.  The Company also has research and development
tax credit carryforwards of approximately $3,700,000 which 
expire in the years 2003 through 2011.

    Deferred tax assets have been reduced to the amount 
realizable, zero, by a valuation allowance based on the 
Company's history of losses.

Liquidity and Capital Resources

     Somatogen's operations to date have consumed substantial 
amounts of cash.  Negative cash flow from operations is expected 
to increase during fiscal 1997 compared to the levels experienced 
in fiscal 1996, and to increase in subsequent fiscal years as the 
clinical trials for Optro increase in scope and the preclinical 
and clinical studies of new products are undertaken.  Somatogen 
will need to raise significant additional funds in order to fund 
the Company's future operations and capital expenditures prior 
to commercialization of the Company's products.  The Company has 
relied primarily on public and private offerings of equity and 
cost sharing and equity investments pursuant to the Lilly Alliance 
to fund its operations and upon equipment leasing arrangements to 
finance the acquisition of capital equipment for the Company's 
laboratory and pilot manufacturing facilities.    

     At June 30, 1996 the Company had cash, cash equivalents and 
short-term investments of $54,276,000.  The Company's cash, cash 
equivalents and short-term investments increased approximately 
$16,367,000 during fiscal 1996.  This increase is primarily due to 
cash proceeds provided from the issuance of common stock offset 
partially by the use of cash for operations.

SOMATOGEN, INC.


     In September 1992, the Company commenced construction of a 
clinical manufacturing facility.  The Company had also acquired 
land for, and begun the design of, a larger commercial 
manufacturing facility.  In conjunction with entering into 
the Lilly Alliance, an evaluation of the Company's future 
manufacturing requirements was completed and construction of 
the clinical manufacturing facility was discontinued.  During 
the fourth quarter of fiscal 1994, the Company recognized a non-
recurring charge, which was principally non-cash, associated 
with the writedown of its clinical and commercial manufacturing 
assets of approximately $29,200,000.  The components of the 
charge included approximately $21,000,000 for the clinical 
manufacturing facility, $6,000,000 for related manufacturing 
equipment and approximately $2,200,000 for engineering design 
costs for the proposed commercial manufacturing facility.  Land 
and building related to manufacturing facilities and the related 
manufacturing equipment aggregating $6,446,000 are classified 
in Somatogen's balance sheet as assets held for sale.  

     For the year ended June 30, 1996, the Company realized 
$941,000 in proceeds from the sale of clinical manufacturing 
assets.  At June 30, 1994, approximately $1,700,000 was recorded 
as an accrual related to obligations resulting from the 
discontinuance of construction of the clinical manufacturing 
facility and related activities.  At June 30, 1996, the balance 
of this accrual is $457,000.  

     The Company believes the aggregate carrying value of all 
assets held for sale approximates the assets' net realizable 
value; however, the Company continues to monitor estimated 
realizable values on a quarterly basis.  There can be no assurance 
that the Company will realize the aggregate carrying value of 
assets held for sale. Proceeds from such asset sales are being 
used for general corporate purposes.

     The Company historically has leased a significant portion of 
the equipment used in its laboratory and pilot manufacturing 
facilities.  As of June 30, 1996, the Company had outstanding 
capital lease obligations of $170,000.  Additionally, the Company 
had aggregate future operating lease obligations of approximately 
$1,700,000 at June 30, 1996.  The Company spent $2,009,000 during 
the year ended June 30, 1996 for the purchase of capital equipment 
and leasehold improvements.

SOMATOGEN, INC.

     During the fiscal year beginning July 1, 1996, the Company's 
operating requirements include increases in research and development
costs, including costs related to clinical trials and product 
development and manufacturing.  The Company's capital spending 
program includes purchases of additional equipment for its research 
and development laboratories and pilot manufacturing facility.  
In subsequent fiscal years, the Company's operating requirements 
will include continuing increases in research and development 
funding to cover the costs of expanded preclinical and clinical 
trials and product development, including reimbursements to Lilly, 
as well as general, administrative, marketing and distribution 
expenses.

     In order to meet its long-term financing requirements, the 
Company may pursue a number of financing alternatives, including 
public and/or private offerings of securities and additional strategic
alliances.  However, there can be no assurance that the Company 
will be able to raise additional financing from any of such sources,
or that any additional funding which may become available to the 
Company will be on acceptable terms.  The Company's ability to 
raise additional financing may be dependent on many factors beyond 
the Company's control, including the state of the capital markets 
and the rate of progress of the Company's clinical field trials.  
Any additional financing that the Company may be able to obtain 
could result in substantial dilution to existing stockholders.  
If adequate funds are not available, the Company will be required 
to significantly curtail operations.  Any such action could impact 
the Company's research and development programs, including the 
Company's clinical field trial program.  Any of these events 
could adversely affect the Company's ability to commercialize
 its products. 

     Cash requirements for the Company may vary materially from 
those now planned due to results of research and development,
results of clinical testing, changes in focus and direction of 
the Company's research and development programs, manufacturing 
processes, competitive and technological advances, the FDA 
regulatory process, changes in the Company's marketing and 
distribution strategy and other factors.

Item 9.  Changes in and Disagreements with Accountants on Accounting
- ------   and Financial Disclosure

     The Company, effective August 24, 1994, engaged Price 
Waterhouse LLP as its independent accountants.  The former 
independent accountants for the Company were Ernst & Young LLP.  
There were no disagreements with Ernst & Young LLP on any matter 
of accounting principles or practices, financial statement 
disclosure, or audit scope or procedure in connection with the 
audits of the Company's financial statements for the fiscal years 
ended June 30, 1994 and 1993 or for any subsequent interim period 
which disagreements, if not resolved to the satisfaction of Ernst & 
Young LLP, would have caused Ernst & Young LLP to make reference 
to the matter in their report, and neither report contained an 
adverse opinion or disclaimer of opinion or was qualified or 
modified as to uncertainty, audit scope or accounting principles.  
The Company has received a letter from its former auditors
concurring with the above statement.  The decision to change 
auditors was recommended by the Company's Audit Committee and

                     Report of Independent Accountants
                     ---------------------------------



To the Board of Directors and Stockholders of
Somatogen, Inc.


In our opinion, the accompanying consolidated balance sheet and the 
related consolidated statements of operations, of stockholders' equity 
and of cash flows present fairly, in all material respects, the 
financial position of Somatogen, Inc. (a development stage enterprise) 
at June 30, 1996 and 1995, and the results of their operations and 
their cash flows for the two fiscal years then ended and for the period 
from inception (June 10, 1985) to June 30, 1996, in conformity with 
generally accepted accounting principles.  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 of these statements in accordance with 
generally accepted auditing standards which 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, assessing the accounting 
principles used and significant estimates made by management, and 
evaluating the overall financial statement presentation.  We believe 
that our audits provide a reasonable basis for the opinion expressed 
above.

                        Report of Independent Auditors
                        ------------------------------

The Board of Directors and Stockholders
Somatogen, Inc.

     We have audited the accompanying consolidated balance sheet of 
Somatogen, Inc. (a corporation in the development stage), as of June 
30, 1994, and the related consolidated statements of operations, 
stockholders' equity and cash flows for the year ended June 30, 1994, 
and for the period from July 10, 1985 (inception) to June 30, 1994 
(not separately  presented herein).   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 consolidated financial statements referred to 
above present fairly, in all material respects, the consolidated 
financial position of Somatogen, Inc. at June 30, 1994, and the 
consolidated results of its operations and its cash flows for the year 
ended   June 30, 1994, and for the period from July 10, 1985 
(inception) to June 30, 1994, in conformity with generally accepted 
accounting principles.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1.  Organization and Summary of Significant Accounting Policies

     Organization:

     Somatogen, Inc. (the "Company") was organized in 1985.  The 
Company has devoted substantially all of its efforts and resources 
since 1987 to research and development related to its recombinant 
hemoglobin technology and is considered to be in the development 
stage.  The Company was reincorporated in the State of Delaware 
in March 1989.  The Company's corporate research and development 
offices and pilot production facility are located in Boulder, Colorado.

     Principles of consolidation:   

     The accompanying consolidated financial statements include the 
accounts of the Company and its previously owned subsidiary.  All 
significant intercompany transactions and accounts have been eliminated
in consolidation.

     Significant estimates:

     The preparation of financial statements in conformity with 
generally accepted accounting principles requires management to make 
estimates and assumptions that affect the reported amounts and 
disclosure of assets and liabilities as of the date of the financial 
statements and the reported amounts of expenses during the periods.  
Significant estimates have been made by management in the preparation
of these financial statements, in particular with respect to the 
carrying value and realizability of the assets held for sale.  Actual
results could differ from estimates making it reasonably possible that
a change in the estimates could occur in the near term.

     Cash and cash equivalents and short-term investments:  

     The Company considers all highly liquid investments with a maturity
of three months or less when purchased to be cash equivalents.  Short-
term investments are carried at cost plus accrued interest and consist
of commercial paper and government obligations, having original 
maturities of longer than three months but less than one year, held 
at financial institutions.  The carrying values of the Company's cash
equivalents and short-term investments approximate their market values
based on quoted market prices.  All cash equivalents and short-term 
investments are expected to be held to maturity.

     Property and equipment purchased are depreciated using the 
straight-line method over their estimated useful lives.  Property and
equipment acquired under capital lease agreements are amortized using 
the straight-line method over the shorter of the useful life or the 
related lease term.  Accumulated depreciation for leased equipment was 
$6,853,000 and $6,526,000 at June 30, 1996 and 1995, respectively.

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     Assets held for sale:

     Land and building related to manufacturing facilities and the 
related manufacturing equipment, aggregating $6,446,000 and 
$7,407,000 at June 30, 1996 and June 30, 1995, respectively, are 
classified as assets held for sale.  These assets are carried at 
their estimated net realizable value (See Note 2).

     Other assets:  

     Other assets at June 30, 1996 and 1995 include approximately 
$1,010,000 and $560,000, respectively, of patent costs, net of 
accumulated amortization, which are capitalized as incurred and 
amortized over a twelve-year period. 

     Revenue recognition: 

     Technology disclosure fees, licensing fees and option payments, 
related to future performance, are deferred and recorded as revenue 
as they are earned over specified future performance periods.  In 
return for contract payments, contract partners have received or 
will receive certain marketing and/or manufacturing rights and 
material for clinical use and testing.  Revenue recognized under 
arrangements with Pharmacia & Upjohn, Inc. aggregated approximately 
$4,500,000 for the period from July 10, 1985 (inception) to June 30, 
1996.   Research and development fees and grant revenue irrevocably 
received are recognized as revenue when received.

     Research and development costs:  

     Research and development costs are expensed as incurred.  These 
costs consist of direct and indirect costs associated with specific 
projects as well as fees paid to various laboratories that conduct 
certain activities on behalf of the Company.

                      (A Corporation in the Development Stage)

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     Pursuant to an alliance between Somatogen and Eli Lilly and 
Company ("Lilly") entered into on June 24, 1994, Lilly is co-
developing Somatogen's lead human hemoglobin product, Optro, sharing
in and being reimbursed for certain clinical development costs and 
contributing advisory and support services.  Expense reimbursements 
from Lilly and payable to Lilly are disclosed as separate components
of research and development in the Consolidated Statement of Operations. 

     Net loss per share:

     Net loss per share is computed using the weighted average number
of shares of common stock outstanding.  Common equivalent shares from
stock options and warrants are excluded from the computation as their
effect would dilute the loss per share for all periods presented.

     New accounting standards:

     In June 1995, the Financial Accounting Standards Board (the 
"FASB") issued Statement of Financial Accounting Standards No. 121, 
Accounting for the Impairment of Long-lived Assets to be Disposed of 
("Statement 121") which requires companies to review long-lived 
assets and certain identifiable intangibles to be held, used or 
disposed of, for impairment whenever events or changes in 
circumstances indicate that the carrying amount of an asset may 
not be recoverable.  The Company is required to adopt Statement 
121 for fiscal 1997.  The Company believes the adoption of 
Statement 121 will not have a significant effect on its financial 
statements.

     In October 1995, the FASB issued Statement of Financial 
Accounting Standards No. 123, "Accounting for Stock-Based 
Compensation" ("Statement 123"), which requires that the Company's 
financial statements include certain disclosures about stock-based 
employee compensation arrangements.  As allowed by Statement 123, 
the Company will continue to apply the accounting provisions of 
Accounting Principles Board Opinion No. 25; accordingly the adoption 
of Statement 123 will have no effect on the Company's financial 
position or results of operations.

     Reclassifications:

     Certain prior year amounts on the consolidated financial 
statements and footnotes have been reclassified to conform to 
the current year presentation.

Note 2.   Lilly Alliance

     In June 1994, the Company entered into a global strategic 
alliance with Lilly whereby Lilly will co-develop Somatogen's 
lead human hemoglobin product, Optro, (the "Lilly Alliance") and 
in September 1995, Somatogen and Lilly agreed to amend certain 
terms of the Lilly Alliance.  Under the terms of the Lilly Alliance,
Lilly is responsible for establishing manufacturing facilities to 
supply Optro for Phase III clinical trials and for global 
commercialization.  In North America, the Company's expanded  
Phase II and Phase III trials for Optro will be performed in 
conjunction with Lilly's clinical and research groups, and Lilly 
and Somatogen will co-promote the product, splitting the development
costs and sharing equally in the profits.  Outside of North America,
except in Scandinavia, Lilly will be responsible for clinical 
development of Optro and related costs, and will have exclusive 
marketing rights.  Lilly will pay Somatogen a royalty on Optro 
sales outside North America.  

     Lilly has invested $30,000,000 in exchange for Somatogen 
common stock, including a $2,000,000 milestone equity investment 
in Somatogen made on September 18, 1995, as a result of Somatogen's 
completion of enrollment in its early Phase II clinical trials and 
a $7,000,000 equity investment made on October 27, 1995 in 
conjunction with Somatogen's October 18, 1995 public common 
stock offering.  The September 1995 amendment to the Lilly 
Alliance accelerated $7,000,000 of the $10,000,000 equity 
investment which Lilly would have made in March 1996 if it 
determined at such time to proceed with the clinical development 
and commercialization of Optro.  In addition, the amendment 
eliminated the March 1996 determination date and combined all 
remaining milestone equity investments into a single $7,000,000 
milestone equity investment to be made if the joint Somatogen-Lilly 
steering committee for the alliance determines that certain 
conditions have been met.

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     The amendment also modified the termination provisions of 
the alliance, which provide for payment of certain financial 
consideration by Lilly to Somatogen in the event that the alliance 
is terminated under certain circumstances.  Pharmacia & Upjohn, 
Inc. has the marketing rights to Optro in Scandinavia under its 
1991 agreement with Somatogen.  

     In accordance with the terms of the Lilly Alliance, Somatogen 
and Lilly share certain development costs.  Pursuant to the September 
1995 amendment, effective January 1, 1996 Somatogen and Lilly began 
to share certain process improvement costs.  

     As a result of the Lilly Alliance, the Company discontinued 
all activity surrounding its clinical and commercial manufacturing 
facilities and reduced the carrying value of these manufacturing 
facilities to their estimated net realizable values during the year
ended June 30, 1994.  The fiscal 1994 charge to operations of 
$29,200,000 included approximately $21,000,000 for the clinical 
manufacturing facility under construction, $6,000,000 for the 
related clinical manufacturing equipment and $2,200,000 for the 
engineering design costs of the commercial manufacturing facility.
Approximately $1,700,000 of the charge was related to liabilities 
accrued at June 30, 1994 to terminate certain construction 
contracts and provide for costs to ready certain assets for sale.  
Approximately $457,000 of this balance is remaining at June 30, 1996.

Note 3.   Income taxes

     At June 30, 1996, the Company had net operating loss 
carryforwards for federal income tax reporting purposes of 
approximately $109,000,000.  Under the federal income tax laws, 
approximately $3,000,000 of these carryforwards cannot be utilized 
due to prior changes in stock ownership.  The remainder of the 
loss carryforwards will expire in the years 2003 through 2011.  
Future changes in stock ownership could result in a further 
limitation on the utilization of present and future loss 
carryforwards.  The Company also has research and development 
tax credit carryforwards of approximately $3,700,000 which will 
expire in the years 2003 through 2011.

</TABLE>

     There were no material deferred tax liabilities as of June 30, 
1996 or June 30, 1995. 

     At June 30, 1996 and 1995, a valuation allowance for deferred 
tax assets of $54,400,000 and $47,100,000, respectively, are required
to reduce the deferred tax assets to the amount realizable, zero, 
based on the Company's history of losses.  The valuation allowance 
increased by $7,300,000 during the year ended June 30, 1996, 
primarily due to additional losses incurred during the year for 
which no tax benefit was recorded. 

Note 4.   Leases

     The Company leases office, production and research and 
development facilities as well as certain equipment under agreements 
that expire at various dates through October 1998.  Total rent 
expense charged to operations for the years ended June 30, 1996,

available lease-line facilities to finance the purchases.  Under the 
terms of certain master lease agreements, the Company has the option 
to purchase the leased equipment at its fair market value or at 
specified percentages of its original cost at the end of the lease

                      (A Corporation in the Development Stage)

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     At June 30, 1996, total shares available for grant under the 
Stock Option Plan, the Consultants' Plan and the Directors'  Plan 
are 148,598, 34,000 and 128,905, respectively,   

     During 1994 certain employees, excluding senior management, 
holding options to purchase shares of the Company's common stock 
exchanged their existing vested and unvested options for the same 
number of options at $7.75 per share which was the market value at 
the date of exchange.  The vesting period on all the replacement 
options began on April 4, 1994 and continues quarterly over a period 
of three years with a term of six years.  Options are not exercisable 
before the first anniversary date of the optionee's employment.  
Options for 103,930 were exchanged in fiscal 1994 and are reflected 
in both the cancellation and grant activity of the preceding 
options outstanding table.

     Warrants:

     As of June 30, 1996, the Company had warrants outstanding 
to purchase 85,000 shares of common stock at an exercise price of 
$9.75 per share. 

     The Company is a party to two separate legal proceedings with 
one individual warrantholder and another group of warrantholders. 
All of the warrantholders have alleged that they are entitled to 
adjustments in the number of shares and the exercise price of their 
warrants, and have asserted claims for securities fraud, common law 
fraud and breach of fiduciary duty.  The trial court has granted 
summary judgment in favor of the Company on all claims of the 
individual warrantholder in May of 1994 and in July of 1995 on all 
claims of the group of warrantholders.  The grant of summary 
judgment on the individual warrantholder's claim was sustained by 
the Colorado Court of Appeals and the Colorado Supreme Court has 
declined to hear the warrantholder's appeal.  The group of 
warrantholders have appealed the grant of summary judgment and 
the Colorado Court of Appeals has not yet rendered a decision on 
such appeal.  The Company believes that the warrantholders' claims 
are without merit, and that the outcome of the litigation will not 
have a material effect on the Company's capital structure or financial
position.   The warrants expired in October 1993.
