##### Table of Contents



Risks Related to Our Liquidity and Need for Financing
 We estimate that our current liquidity and capital resources are sufficient to fund our operations
into early 2010. However, we will need substantial additional funds to expand operations, which we
may not be able to raise on favorable terms, or at all.
     We are seeking to maximize the value of our assets and to address our liabilities and raise
additional capital for our existing business. We are attempting to pursue asset out-licenses, asset
sales, mergers or similar strategic transactions. There can be no assurance that we will be
successful in executing a strategic transaction.
   17




---



##### Table of Contents



We have incurred losses since inception and expect to incur significant losses in the foreseeable
future and may never become profitable.
   The recent downturn in the U.S. economy and the recent pressure on capital markets increase the
possibility of and may exacerbate the impact of any adverse effects on our financial position and
business prospects. Continued economic adversity may lead to or accelerate a decrease in the
trading price of our common stock and make it more difficult for us to raise capital, enter into
collaborations or maintain our compliance with the minimum listing standards of the NYSE Amex stock
exchange.
   18




---



##### Table of Contents



If we are unable to successfully implement our cash preservation efforts, our business could be
materially adversely affected.
  We are currently not in compliance with NYSE Amex rules regarding the minimum shareholders equity
requirement and are at risk of being delisted from the NYSE Amex stock exchange, which may subject
us to the SECs penny stock rules and decrease the liquidity of our common stock. If our common
stock is delisted, this would likely make capital raising efforts more difficult.
      19

##### Table of Contents



In addition to our current operational requirements, we will need substantial additional capital to
develop our product candidates and for our future operations. If we are unable to obtain such funds
when needed, we may have to delay, scale back or terminate our product development efforts or our
business.
  
    
    the scope of our clinical trials, which is significantly influenced by
the quality of clinical data achieved as trials are completed and the
requirements established by regulatory authorities;
    
    the speed with which we complete our clinical trials, which depends on
our ability to attract and enroll qualifying patients and the quality
of the work performed by our clinical investigators;
    
    the time required to prosecute, enforce and defend our intellectual
property rights, which depends on evolving legal regimes and
infringement claims that may arise between us and third parties;
    
    the ability to manufacture at scales sufficient to supply commercial
quantities of any of our product candidates that receive regulatory
approval, which may require levels of effort not currently
anticipated; and
    
    the successful commercialization of our product candidates, which will
depend on our ability to either create or partner with an effective
commercialization organization and which could be delayed or prevented
by the emergence of equal or more effective therapies.
   20

##### Table of Contents



Risks Related to Our Business and Operations
 Our business prospects are difficult to evaluate because we are developing complex and novel
medical product candidates.
  
    
    limited financial resources;
    
    developing novel, commercial-grade drug substances;
    
    testing and evaluating a new chemical entity and its effects in
highly-complex biological systems;
    
    marketing new products for which a market is not yet established and
may never become established;
    
    challenges related to the approval and acceptance of drug candidates
by United States federal and international regulatory authorities;
    
    delays inherent in the execution of clinical trials;
    
    high product development costs that result from all of these factors;
    
    competition from other therapies and drug candidates promoted by
entities with significantly more capital resources and marketing
expertise than us; and
    
    difficulty recruiting qualified employees for management and other positions.
  21

##### Table of Contents



We may not successfully establish and maintain development and testing relationships with third
party service providers and collaborators, which could adversely affect our ability to develop our
product candidates.
   
    
    we do not achieve our objectives under our collaboration agreements;
    
    we or our collaborators are unable to obtain patent protection for the
products or proprietary technologies we develop in our collaborations;
    
    we are unable to manage multiple simultaneous product development
collaborations;
    
    our collaborators become competitors of ours or enter into agreements
with our competitors;
    
    we or our collaborators encounter regulatory hurdles that prevent
commercialization of our product candidates; or
    
    we develop products and processes or enter into additional
collaborations that conflict with the business objectives of our other
collaborators.

##### Table of Contents



We are subject to intense government regulation and we may not receive regulatory approvals for our
new drug candidates.
   
    
    the FDA or other health regulatory authorities, or IRBs, do not
approve a clinical trial protocol or place a clinical trial on hold;
    
    suitable patients do not enroll in a clinical trial in sufficient
numbers or at the expected rate, or data is adversely affected by
trial conduct or patient drop out;
    
    patients experience serious adverse events, including adverse side
effects of our drug candidates, for a variety of reasons that may or
may not be related to our product candidates, including the advanced
stage of their disease and other medical problems;
    
    patients in the placebo or untreated control group exhibit greater
than expected improvements or fewer than expected adverse events;
    
    third-party clinical investigators do not perform the clinical trials
on the anticipated schedule or consistent with the clinical trial
protocol and good clinical practices, or other third-party
organizations do not perform data collection and analysis in a timely
or accurate manner;

##### Table of Contents




    
    service providers, collaborators or co-sponsors do not adequately
perform their obligations in relation to the clinical trial or cause
the trial to be delayed or terminated;
    
    regulatory inspections of manufacturing facilities, which may, among
other things, require us or a co-sponsor to undertake corrective
action or suspend the clinical trials;
    
    the interim results of the clinical trial are inconclusive or negative;
    
    the clinical trial, although approved and completed, generates data
that is not considered by the FDA or others to be sufficient to
demonstrate safety and efficacy; and
    
    changes in governmental regulations or administrative actions affect
the conduct of the clinical trial or the interpretation of its
results.
  Mauro Bove, a member of our Board, is also a director and officer of Sigma-Tau Finanziaria S.p.A,
which together with its affiliates comprise our largest stockholder group, a relationship which
could give rise to a conflict of interest involving Mr. Bove.

We are heavily reliant on our license from the National Institutes of Health for the rights to Tß4,
and any loss of these rights would adversely affect our business.
  All of our drug candidates are based on a single compound that has yet to be proven effective in
human subjects.

    be found ineffective or cause harmful side effects during pre-clinical
studies or clinical trials;
    
    fail to receive necessary regulatory approvals;
    
    be precluded from commercialization by proprietary rights of third parties;
    
    be difficult to manufacture on a large scale; or
    
    be uneconomical or otherwise fail to achieve market acceptance.
  We have no manufacturing or formulation capabilities and are dependent upon third-party suppliers
to provide us with our product candidates. If these suppliers do not manufacture our product
candidates in sufficient quantities, at acceptable quality levels and at acceptable cost, or if we
are unable to identify suitable replacement suppliers if needed, our clinical development efforts
could be delayed, prevented or impaired.
