many solid tumors and treating the hypoxic environment is currently believed to be a significant unmet medical need. Our product candidates are designed to selectively target the hypoxic microenvironment of tumors either by selective toxin
activation in the case of our hypoxia activated prodrug (HAP) program, including TH-302, or potentially utilizing the consequences of increased uptake of glucose in cancer cells relative to most normal cells. Our product candidate 2-deoxyglucose
(&#147;2DG&#148;) and our recently out-licensed product candidate glufosfamide share certain structural characteristics with glucose but act instead as chemotherapeutic toxins when taken up by a cell. </FONT></P> <P

radiation and drugs or a combination of these approaches. Drugs used to treat cancer include chemotherapeutics, hormones and immune-based therapies. Traditionally, strategies for designing cancer therapies have focused on killing cancer cells that
exhibit rapid division and growth, and most conventional cancer drugs have been evaluated and optimized using cellular and animal models that reflect rapid cell growth. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;

 <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">However, most solid tumors are actually composed of both rapidly and slowly dividing cells.
Conventional cancer treatments are not designed to target the slowly dividing cells found in portions of solid tumors and therefore typically do not succeed in killing all cancerous cells. As a tumor grows, its vasculature is disordered and chaotic,
leaving portions of the tumor with regions where the oxygen concentration is significantly lower than in healthy tissues. This condition is called Tumor Hypoxia. Solid tumors have significant hypoxic regions, and because these regions have limited
access to the blood supply and oxygen, the cells in them divide slowly, making them resistant to traditional chemotherapy and radiation treatment, which target rapidly dividing cells. Similarly, chemotherapeutic agents delivered in the blood supply
are less able to penetrate into hypoxic regions because they are more distant from the blood supply. Moreover, many scientists now believe that hypoxia can lead to genetic mutations, which can give rise to drug resistance and enhanced metastatic
potential. Thus, therapeutics that target hypoxic zones could provide significant additional anti-tumor activity and clinical benefit over current chemotherapeutic and radiation therapies. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Another disadvantage of current cancer therapies that target rapidly dividing cells is their toxic side effects. Because rapidly dividing
cells are also found in many healthy tissues, particularly the gastrointestinal tract, bone marrow and hair follicles, nearly all conventional chemotherapy drugs cause severe side effects, such as diarrhea and reduction in blood cell production,
which may lead to bleeding, infection and anemia, as well as other side effects, such as hair loss. Likewise, radiation generally cannot be administered without causing significant damage to healthy tissue surrounding a tumor. Since TH-302 and
glufosfamide are inactive prodrugs, it is believed that they should not produce the typical adverse side effects associated with chemotherapy observed in otherwise normal healthy tissues. Since our prodrugs are designed to undergo tumor selective
activation, we anticipate that they should have a favorable safety profile and produce less toxicity to normal tissues at the doses that are effective in treating tumors than is the case with traditional therapies. </FONT></P> <P

anticancer activity in multiple preclinical cancer models. TH-302 combines a 2-nitroimidazole oxygen-sensing trigger with a masked deoxyribonucleic acid (&#147;DNA&#148;) crosslinker.&nbsp;Upon
activation in oxygen deficient zones, TH-302 is converted selectively to the drug&#146;s active form, dibromo isophosphoramide mustard, a potent alkylator. TH-302 targets levels of severe hypoxia that are found in tumors but are rare in normal
tissues&#151;this is how selective targeting of the tumor occurs. After conversion to the active form of the drug, the hypoxic cells are exposed to high concentrations of released cytotoxic agent, which can also diffuse into the adjacent regions of
the tumor. We believe that TH-302 will be less likely to produce the systemic hematologic toxicity caused by most cytotoxic chemotherapies, while targeting the hypoxic regions of tumors known to be more difficult to treat with standard therapies.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In addition to all of the standard toxicity and pharmacokinetic studies that are required to enable an investigational new
drug (IND) application, numerous <I>in vitro</I> and <I>in vivo</I> efficacy studies with TH-302 have been conducted. A summary of the pre-clinical efficacy studies with TH-302 follows. In over 20 different human tumor-derived cell lines,
representing 13 different tumor types, have been evaluated for their sensitivity to TH-302 and all were shown to have enhanced sensitivity to TH-302 under hypoxic conditions compared to higher oxygen concentrations. No cell lines that were
investigated were resistant to TH-302 under hypoxic conditions. In addition, we have also evaluated TH-302 in ectopic xenograft models of cancer, in which human tumor cells are implanted beneath the skin of mice and permitted to grow as tumors. More
than 20 of these studies were conducted using five different tumor types and multiple drug combinations. In all of these models, the combination of TH-302 with either chemotherapeutic agents or radiation consistently added efficacy above that seen
with the single agent chemotherapeutic. We conducted animal studies of TH-302&nbsp;in orthotopic mouse models of human cancer, in which human cancer cells are implanted into the corresponding mouse tissue and tumors are allowed to develop before
treatment, to assess&nbsp;the efficacy&nbsp;of TH-302 in treating a variety of cancer types.&nbsp;In these models, TH-302 demonstrated promising efficacy when used in combination with standard chemotherapeutic agents. In an orthotopic mouse model of
human pancreatic cancer,&nbsp;in which mice were treated with either gemcitabine or gemcitabine in combination with TH-302, complete responses were observed in one out of eight animals treated with TH-302 in combination with gemcitabine.&nbsp;In
comparison, no complete responses were seen following single-agent gemcitabine.&nbsp;In a similar mouse model of human prostate cancer, complete responses were observed in four out of eight animals treated with TH-302 in combination with
taxol.&nbsp;In comparison, no complete responses were reported with single-agent taxol.&nbsp;TH-302 was also tested in combination with docetaxel therapy in a metastatic mouse model of human hormone refractory prostate cancer.&nbsp;The combination
of TH-302 with docetaxel resulted in eight out of ten complete responses.&nbsp;In comparison, three out of eight complete responses were reported with single-agent docetaxel. Most recently, TH-302 has been evaluated in a metastatic mouse model of
human lung cancer, alone and in combination with docetaxel. These preclinical results, which reflect our overall experience with cell-based animal models, indicate that combination therapies with TH-302 may be efficacious in the treatment of human
solid tumors. There can be no assurance, however, that these animal studies will accurately predict the results of human clinical trials. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; margin-left:4%"><FONT

STYLE="font-family:Times New Roman" SIZE="2">2DG, for the treatment of solid tumors, was investigated in a Phase 1 clinical trial. 2DG is an orally administered small molecule that aims to treat solid tumors by directly inhibiting glycolysis.
Because tumor cells in general and those in hypoxic zones in particular, are dependent on glycolysis for survival, tumor cells are particularly sensitive to the effect of 2DG. This compound is a synthetic glucose analog that distributes selectively
to tumor tissue because of metabolic changes related to increased glucose consumption. Because tumor cells exhibit increased levels of glucose transport proteins, these cells actively transport 2DG into the cells. Once inside the cell, 2DG
interferes with cellular mechanisms for generating energy by competing with glucose for key enzymes in glycolysis. The <I>in vivo</I> efficacy of 2DG has been studied in mouse and rat models of certain cancers, including sarcomas, adenocarcinomas,
leukemias, melanomas and bladder, colon and breast tumors. In particular, treatment with 2DG, alone and in combination with other chemotherapy resulted in increased lifespan or a reduction in tumor growth in many of these models. Animal studies
suggest that 2DG and docetaxel may work together to kill cancer cells with greater efficacy than either drug alone, without increased risk of side-effects. We developed 2DG based on its specificity for targeting tumor cells and extensive human
safety data, as well as demonstrated animal efficacy that we and our collaborators at the University of Miami published in <I>Cancer Research</I> in January 2004. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

with docetaxel. The clinical trial enrolled patients with previously treated refractory advanced solid tumors. The clinical trial evaluated the effect of 2DG alone and in combination with docetaxel on tumor growth, and provided a preliminary
assessment of efficacy, as assessed by computer tomography. Data from this clinical trial was initially reported at American Society of Clinical Oncology 2005 annual meeting and has been periodically updated. The data suggest that 2DG is well

solid tumors.&nbsp;Solid tumors possess chaotic and insufficient blood flow resulting in regions which are hypoxic or otherwise starved for oxygen. These extremely low oxygen conditions are not found in normal tissues and these hypoxic zones are
found in virtually all solid tumors. The hypoxic zones of tumors are known to be resistant to standard chemotherapeutics and to radiation therapy.&nbsp;Tumor hypoxia correlates with poor prognosis in cancer patients and represents a significant
unmet medical need.&nbsp;The general nature of hypoxia in solid tumors offers the possibility for cancer therapeutics which are broadly useful in many indications with an associated large market opportunity. </FONT></P> <P

inactive compound that is converted in the human body by enzymatic processes that result in the formation of an active drug. The prodrug concept is well established in chemotherapy and, was initially only employed to modify the pharmacokinetic
properties of compounds through non-specific activation processes. More recently has the concept been applied to the design of agents that are selectively activated in tumor tissues through specific activation processes. </FONT></P> <P

and an attached trigger molecule. To prevent general toxicity, the trigger molecule masks the toxin until the prodrug is activated by the low oxygen concentration in the hypoxic zones of solid tumors.&nbsp;Once activated, the toxin kills cells in
its vicinity. We have designed prodrug candidates that are triggered only at the very low oxygen levels found in these hypoxic regions. Our experiments indicate that we can achieve a greater than 100-fold difference in cytotoxicity between cells in
normal oxygen levels and hypoxic cells. Our lead investigational drug candidate, TH-302, was our first product candidate from this program. TH-302 is highly selective and produces a conventional DNA cross-linking toxin upon activation. Hypoxia

large number of patents and frequent litigation based on allegations of patent infringement. For so long as our product candidates are in clinical trials, we believe our clinical activities fall within the scope of the exemptions provided by
35&nbsp;U.S.C. Section&nbsp;271(e) in the United States, which exempts from patent infringement liability activities reasonably related to the development and submission of information to the FDA. This exemption does not apply to commercialization
activities, however; if our product candidates are commercialized, then the possibility of a patent infringement claim against us increases. While we attempt to ensure that our clinical product candidates and the methods we employ to manufacture
them, as well as the methods for their use we intend to promote, do not infringe other parties&#146; patents and other proprietary rights, there can be no assurance that they do not, and competitors or other parties may assert that we infringe their

SIZE="2">In the United States, drug candidates are tested in animals until adequate proof of safety is established. These preclinical studies generally evaluate the mechanism of action of the product and assess the potential safety and efficacy of
the product. Tested compounds must be produced according to applicable current good manufacturing practice, or cGMP, requirements and preclinical safety tests must be conducted in compliance with FDA and international regulations regarding good
laboratory practices, or GLP. The results of the preclinical tests, together with manufacturing information and analytical data, are generally submitted to the FDA as part of an IND, which must become effective before human clinical trials may
commence. The IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA requests an extension or raises concerns about the conduct of the clinical trials as outlined in the application. If the FDA has
any concerns, the sponsor of the application and the FDA must resolve the concerns before clinical trials can begin. Submission of an IND may not result in FDA authorization to commence a clinical trial. A separate submission to the existing IND
must be made for each successive clinical trial conducted during product development, and the FDA must grant permission for each clinical trial to start and continue. Regulatory authorities may require additional data before allowing the clinical
trials to commence or proceed from one Phase to another, and could demand that the trials be discontinued or suspended at any time if there are significant safety issues. Furthermore, an independent institutional review board, or IRB, for each
medical center proposing to participate in the conduct of the clinical trial must review and approve the clinical protocol and patient informed consent before the center commences the clinical trial. </FONT></P> <P

SIZE="2">Clinical trials for new drug candidates are typically conducted in three sequential phases that may overlap. In Phase 1 involves the initial introduction of the drug candidate into humans and are conducted in volunteers or in patients with
a specific disease depending on the intended use. The emphasis in Phase 1 is on testing for safety or adverse effects, dosage, tolerance, metabolism, distribution, excretion, and clinical pharmacology. Phase 2 involves clinical trials in a limited
patient population to determine the initial efficacy of the drug candidate for specific targeted indications, to determine dosage tolerance and optimal dosage and to identify possible adverse side effects and safety risks. Once a compound shows
evidence of effectiveness and is found to have an acceptable safety profile in Phase 2 clinical trials, pivotal controlled Phase 3 clinical trials are undertaken to more fully evaluate clinical outcomes and to establish the overall risk/benefit
profile of the drug, and to provide, if appropriate, an adequate basis for product labeling. During all clinical trials, physicians monitor patients to determine effectiveness of the drug candidate and observe and report any reactions or safety
risks that may result from use of the drug candidate. The FDA, the IRB, or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk. </FONT></P>

candidate&#146;s safety, are submitted to the FDA in the form of an NDA or NDA supplement (for approval of a new indication if the product candidate is already approved for another indication). Under applicable laws and FDA regulations, each NDA
submitted for FDA approval is usually given an internal administrative review within 45 to 60 days following submission of the NDA. If deemed complete, the FDA will &#147;file&#148; the NDA, thereby triggering substantive review of the application.
The FDA can refuse to file any NDA that it deems incomplete or not properly reviewable. The FDA has established internal substantive review goals

legally required to complete its review within these periods, and these performance goals may change over time. Moreover, the outcome of the review, even if generally favorable, is not typically an actual approval, but an &#147;action letter&#148;

time and expense required to bring a product to market may vary substantially. We cannot be certain that we will submit applications for required authorizations to manufacture and/or market potential products or that any such application will be
reviewed and approved by the appropriate regulatory authorities in a timely manner, if at all. Data obtained from clinical activities is not always conclusive and may be susceptible to varying interpretations, which could delay, limit, or prevent
regulatory approval. Success in early stage clinical trials does not ensure success in later stage clinical trials. Even if a product candidate receives regulatory approval, the approval may be significantly limited to specific disease states,
patient populations, and dosages, or have conditions placed on them that restrict the commercial applications, advertising, promotion, or distribution of these products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

and surveillance programs to monitor the effect of approved products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs. The FDA may also
request additional clinical trials after a product is approved. These so-called Phase 4 studies may be made a condition to be satisfied after a drug receives approval. The results of Phase 4 studies can confirm the effectiveness of a product
candidate and can provide important safety information to augment the FDA&#146;s voluntary adverse drug reaction reporting system. The product may be subject to withdrawal of the approval if effectiveness is not confirmed in the Phase 4 studies. Any
products manufactured or distributed by us pursuant to FDA approvals would be subject to continuing regulation by the FDA, including record-keeping requirements and reporting of adverse experiences with the drug. Drug manufacturers and their
subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with good manufacturing practices, which
impose certain procedural and documentation requirements upon us and our third-party manufacturers. We cannot be certain that we or our present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory
requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may halt our clinical trials, require us to recall a drug from distribution, or withdraw approval of the NDA for that drug. Furthermore, even
after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. </FONT></P> <P

Track&#148; approval of potential products intended to treat serious or life-threatening illnesses that have been studied for safety and effectiveness and that demonstrate the potential to address unmet medical needs. The procedures permit early
consultation and commitment from the FDA regarding the preclinical and clinical trials necessary to gain marketing approval. Provisions of this regulatory framework also permit, in certain cases, NDAs to be approved on the basis of valid indirect
measurements of benefit of product effectiveness, thus accelerating the normal approval process. Certain potential products employing our technology might qualify for this accelerated regulatory procedure. Even if the FDA agrees that these potential
products qualify for accelerated approval procedures, the FDA may deny approval of our drugs or may require additional clinical trials before approval. The FDA may also require us to perform post-approval, or Phase 4, studies as a condition of such
early approval. In addition, the FDA may impose restrictions on distribution and/or promotion in connection with any accelerated approval, and may withdraw approval if post-approval studies do not confirm the intended clinical benefit or safety of

STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition, which is
generally a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the identity of the therapeutic
agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. If a product that has orphan drug designation
subsequently receives FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same
disease, except in limited circumstances, for seven years. These circumstances are an inability to supply the drug in sufficient quantities or a situation in which a new formulation of the drug has shown superior safety or efficacy. This
exclusivity, however, also could block the approval of our product for seven years if a competitor obtains earlier approval of the same drug for the same indication. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

federal healthcare programs. In addition, many states have adopted laws similar to the federal Anti-Kickback Law. Some of these state prohibitions apply to referral of patients for healthcare
services reimbursed by any source, not only the Medicare and Medicaid programs. Due to the breadth of these laws, and the potential for additional legal or regulatory change addressing some of our practices, it is possible that our practices or our
relationships with physicians might be challenged under anti-kickback laws, which could harm us. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">False claims laws prohibit
anyone from knowingly presenting, or causing to be presented, for payment to third-party payors (including Medicare and Medicaid) claims for reimbursed items or services, including drugs, that are false or fraudulent, claims for items or services
not provided as claimed, or claims for medically unnecessary items or services. Our future activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of Medicaid rebate information and other
information affecting federal, state and third-party reimbursement of our products, and the sale and marketing of our products, are subject to scrutiny under these laws. In addition, pharmaceutical companies have been prosecuted under the federal
False Claims Act in connection with their off-label promotion of drugs. Penalties for a violation include three times the actual damages sustained by the government, plus mandatory civil penalties of between $5,500 and $11,000 for each separate
false claim. In addition, certain states have enacted laws modeled after the federal False Claims Act. If the government were to allege that we were, or convict us of, violating these false claims laws, we could be subject to a substantial fine and
suffer a decline in our stock price. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; margin-left:2%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><I>Drug Price Competition and Patent Term Restoration Act of 1984 </I></FONT></P> <P
STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Under the Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Amendments, a portion of a product&#146;s
patent term that was lost during clinical development and application review by the FDA may be restored. The Hatch-Waxman Amendments also provide for a statutory protection, known as nonpatent market exclusivity, against the FDA&#146;s acceptance or
approval of certain competitor applications. The Hatch-Waxman Amendments also provide the legal basis for the approval of abbreviated new drug applications, or ANDAs, for generic drugs. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Patent term restoration can compensate for patent life lost during product development and the regulatory review process by returning up to
five years of patent life for a patent that covers a new product or its use. This period is generally one-half the time between the effective date of an IND (falling after issuance of the patent) and the submission date of an NDA, plus the time
between the submission date of an NDA and the approval of that application. Patent term restorations, however, are subject to a maximum extension of five years, and the patent term restoration cannot extend the remaining term of a patent beyond a
total of 14 years. The application for patent term extension is subject to approval by the United States Patent and Trademark Office in conjunction with the FDA. It takes at least six months to obtain approval of the application for patent term
extension. Up to five years of interim one year extensions are available if a product is still undergoing development or FDA review at the time of its expiration. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">The Hatch-Waxman Amendments also provide for a period of statutory protection for new drugs that receive NDA approval from the FDA. If a new drug receives NDA approval as a new chemical entity, meaning
that the FDA has not previously approved any other new drug containing the same active moiety, then the Hatch-Waxman Amendments prohibit an abbreviated new drug application or an NDA where the applicant does not own or have a legal right of
reference to all of the data required for approval, or a &#147;505(b)(2)&#148; NDA, to be submitted by another company for a generic version of such drug, with some exceptions, for a period of five years from the date of approval of the NDA. The
statutory protection provided pursuant to the Hatch-Waxman Amendments will not prevent the filing or approval of a full NDA. In order to gain approval of a full NDA, however, a competitor would be required to conduct its own preclinical
investigations and clinical trials. If NDA approval is received for a new drug containing an active ingredient that was previously approved by the FDA but the NDA is for a drug that includes an innovation over the previously approved drug, for
example, an NDA approval for a new indication or formulation of the drug with the same active ingredient, and if such NDA approval was dependent upon the submission to the FDA of new clinical investigations, other than bioavailability

studies, then the Hatch-Waxman Amendments prohibit the FDA from making effective the approval of an ANDA or a 505(b)(2) NDA for a generic version of such drug for a period of three years from the
date of the NDA approval. This three year exclusivity, however, only covers the innovation associated with the NDA to which it attaches. Thus, the three year exclusivity does not prohibit the FDA, with limited exceptions, from approving ANDAs or
505(b)(2) NDAs for drugs containing the same active ingredient but without the new innovation. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">While the Hatch-Waxman
Amendments provide certain patent term restoration and exclusivity protections to innovator drug manufacturers, it also permits the FDA to approve ANDAs for generic versions of their drugs. The ANDA process permits competitor companies to obtain
marketing approval for a drug with the same active ingredient for the same uses but does not require the conduct and submission of clinical trials demonstrating safety and effectiveness for that product. Instead of safety and effectiveness data, an
ANDA applicant needs only to submit data demonstrating that its product is bioequivalent to the innovator product as well as relevant chemistry, manufacturing and control data. The Hatch-Waxman Amendments also instituted a third type of drug
application that requires the same information as an NDA including full reports of clinical and preclinical studies except that some of the information from the reports required for marketing approval comes from studies which the applicant does not
own or have a legal right of reference. This type of application, a &#147;505(b)(2) NDA,&#148; permits a manufacturer to obtain marketing approval for a drug without needing to conduct or obtain a right of reference for all of the required studies.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Finally, the Hatch-Waxman Amendments require, in some circumstances, an ANDA or a 505(b)(2) NDA applicant to notify the
patent owner and the holder of the approved NDA of the factual and legal basis of the applicant&#146;s opinion that the patent listed by the holder of the approved NDA in FDA&#146;s Orange Book is not valid or will not be infringed (the patent
certification process). Upon receipt of this notice, the patent owner and the NDA holder have 45 days to bring a patent infringement suit in federal district court and obtain a 30-month stay against the company seeking to reference the NDA. The NDA
holder could still file a patent suit after the 45 days, but if they did, they would not have the benefit of the 30-month stay. Alternatively, after this 45-day period, the applicant may file a declaratory judgment action, seeking a determination
that the patent is invalid or will not be infringed. Depending on the circumstances, however, the applicant may not be able to demonstrate a controversy sufficient to confer jurisdiction on the court. The discovery, trial and appeals process in such
suits can take several years. If such a suit is commenced, the Hatch-Waxman Act provides a 30-month stay on the approval of the competitor&#146;s ANDA or 505(b)(2) NDA. If the litigation is resolved in favor of the competitor or the challenged
patent expires during the 30-month period, unless otherwise extended by court order, the stay is lifted and the FDA may approve the application. Under regulations recently issued by the FDA, and essentially codified under the recent Medicare
prescription drug legislation, the patent owner and the NDA holder have the opportunity to trigger only a single 30-month stay per ANDA or 505(b)(2) NDA. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; text-indent:2%"><FONT

registry of open clinical trials involving drugs intended to treat serious or life-threatening diseases or conditions was established under the Food and Drug Administration Modernization Act, or FDMA, in order to promote public awareness of and
access to these clinical trials. Under FDMA, pharmaceutical manufacturers and other clinical trial sponsors are required to post the general purpose of these clinical trials, as well as the eligibility criteria, location and contact information of
the clinical trials. Since the establishment of this registry, there has been significant public debate focused on broadening the types of clinical trials included in this or other registries, as well as providing for public access to clinical trial
results. A voluntary coalition of medical journal editors has adopted a resolution to publish results only from those clinical trials that have been registered with a no-cost, publicly accessible database, such as
<U>http://www.clinicaltrials.gov</U>. The Pharmaceuticals and Research Manufacturers of America has also issued voluntary principles for its members to make results from certain clinical trials publicly available and has established a website for
this purpose. Other groups have adopted or are considering similar proposals for clinical trial registration and the posting of clinical trial results. The state of Maine has enacted legislation, with penalty provisions, requiring the disclosure of
results from clinical trials involving drugs marketed in the state, and similar legislation has been introduced in other states. Federal legislation was introduced in the fall of 2004 to expand <U>http://www.clinicaltrials.gov</U> and to require the
inclusion of clinical trial results in this registry. In some states, such as New York, prosecutors have alleged that a lack of disclosure of clinical trial information constitutes fraud, and these allegations have resulted in settlements with
pharmaceutical companies that include agreements to post clinical trial results. Our failure to comply with any clinical trial posting requirements could expose us to negative publicity, fines, and other penalties, all of which could materially harm
our business. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Risks Related to Our Financial Performance and Operations </B></FONT></P> <P

clinical setting in which it is used, may be based on payments allowed for lower-cost drugs that are already reimbursed, may be incorporated into existing payments for other products or services, and may reflect budgetary constraints and/or Medicare
or Medicaid data used to calculate these rates. Net prices for products also may be reduced by mandatory discounts or rebates required by government health care programs or by any future relaxation of laws that restrict imports of certain medical

experiencing a trend toward containing or reducing costs through various means, including lowering reimbursement rates, limiting therapeutic class coverage and negotiating reduced payment schedules with service providers for drug products. The
Medicare Prescription Drug, Improvement and Modernization Act of 2003, or MMA, became law in November&nbsp;2003 and created a broader prescription drug benefit for Medicare beneficiaries. The MMA also contains provisions intended to reduce or
eliminate delays in the introduction of generic drug competition at the end of patent or nonpatent market exclusivity. The impact of the MMA on drug prices and new drug utilization over the next several years is unknown. The MMA also made
adjustments to the physician fee schedule and the measure by which prescription drugs are presently paid, changing from Average Wholesale Price to Average Sales Price. The effects of these changes are unknown but may include decreased utilization of
new medicines in physician prescribing patterns, and further pressure on drug company sponsors to provide discount programs and reimbursement support programs. There have been, and we expect that there will continue to be, federal and state
proposals to constrain expenditures for medical products and services, which may affect reimbursement levels for our future products. In addition, the Centers for Medicare&nbsp;&amp; Medicaid Services frequently change product descriptors, coverage
policies, product and service codes, payment methodologies and reimbursement values. Third-party payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates and may have sufficient market power to
demand significant price reductions. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; text-indent:2%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B><I>Foreign governments tend to impose strict price controls, which may adversely

being quoted on the NASDAQ Capital Market. Previously, we had fallen out of compliance with continued listing requirements because our common stock did not comply with the $1.00 minimum bid price requirement for continued listing set forth in NASDAQ
Marketplace Rule&nbsp;5450(a)(1) (formerly Rule&nbsp;4450(a)(5)). To regain compliance, effective August&nbsp;20, 2008, we implemented a 1-for-6 reverse stock split of our common stock. After that date, our common stock traded above the minimum
$1.00 bid price for at least ten consecutive business days and on September&nbsp;5, 2008, the NASDAQ Stock Market notified us that we had regained compliance with the minimum bid price requirements. On October&nbsp;16, 2008, the NASDAQ Stock Market
suspended the enforcement of the minimum bid price and market value requirements through January&nbsp;16, 2009. The suspension period was subsequently extended to July&nbsp;31, 2009 and NASDAQ&#146;s enforcement of these rules resumed on Monday,
August&nbsp;3, 2009. NASDAQ does not expect any further extensions of the suspension. Even though we regained compliance with the minimum bid price, we cannot assure you that we will be able to maintain compliance with the minimum bid price
requirement or other listing requirements in the future, and our failure to do so could result in the delisting of our shares from the NASDAQ Capital Market. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px; text-indent:2%"><FONT

at an exercise price of $2.23 per share. In addition, on August&nbsp;29, 2008, we issued outstanding warrants to purchase an aggregate of 3,588,221&nbsp;shares of our common stock, at an exercise price of $2.34 per share, which exercise price was
subsequently reduced to $1.86 per share on October&nbsp;5, 2009 under the anti-dilution provisions of the warrants as a result of the October 2009 private placement that was completed on that date. The exercise price and/or the number of shares of
common stock issuable upon exercise of the warrants may be adjusted in certain circumstances, including certain issuances of securities at a price equal to less than the then current exercise price, subdivisions and stock splits, stock dividends,
combinations, reorganizations, reclassifications, consolidations, mergers or sales of properties and assets and upon the issuance of certain assets or securities to holders of our common stock, as applicable. Although we cannot determine at this
time which of these warrants will ultimately be exercised, it is reasonable to assume that such warrants will be exercised only if the exercise price is below the market price of our common stock. To the extent the warrants are exercised, additional
shares of our common stock will be issued that will be eligible for resale in the public market, which will result in dilution to our security holders. The issuance of additional securities could also have an adverse effect on the market price of

motions to dismiss that complaint but afforded the plaintiffs leave to file a further amended complaint. On September&nbsp;19, 2008, the plaintiffs filed a second consolidated amended complaint, which, on behalf of an alleged class of purchasers of
our common stock from the date of our initial public offering of securities on February&nbsp;4, 2005 through July&nbsp;14, 2006,&nbsp;purports to allege claims arising under Sections&nbsp;11, 12(a)(2) and 15 of the Securities Act and under Sections
10(b) and 20(a) of the Exchange Act. The plaintiffs allege generally that the defendants violated the federal securities laws by, among other things, making material misstatements or omissions concerning our Phase 2 and Phase 3 clinical trials of
Lonidamine (TH-070).&nbsp;On&nbsp;November&nbsp;14, 2008, Defendants moved to dismiss the second consolidated amended complaint. On April&nbsp;3, 2009, the Court granted in part and denied in part the motions to dismiss, dismissing with prejudice
all claims arising under the Securities Act and all claims against Ms.&nbsp;Swearson, while narrowing the remaining claims. On October&nbsp;30, 2009, the parties entered into a stipulation&nbsp;of settlement to resolve the lawsuit.&nbsp;The

July&nbsp;5 and July&nbsp;18, 2007, purported shareholder class action complaints alleging violations of the federal securities laws were filed against us, our Chief Executive Officer Harold E. Selick and our former Chief Financial Officer Janet I.
Swearson in the United States District Court for the Southern District of New York.&nbsp;On September&nbsp;14, 2007, these lawsuits, which have been&nbsp;consolidated by the Court into a single proceeding,&nbsp;were ordered transferred to the United
States District Court for the Northern District of California.&nbsp;On January&nbsp;15, 2008, the plaintiffs filed a first consolidated amended complaint. On July&nbsp;11, 2008, the Court granted Defendants&#146; motions to dismiss that complaint
but afforded the plaintiffs leave to file a further amended complaint. On September&nbsp;19, 2008, the plaintiffs filed a second consolidated amended complaint, which, on behalf of an alleged class of purchasers of our common stock from the date of
our initial public offering of securities on February&nbsp;4, 2005 through July&nbsp;14, 2006,&nbsp;purports to allege claims arising under Sections 11, 12(a)(2) and 15 of the Securities Act, and under Sections 10(b) and 20(a) of the Exchange Act.
Plaintiffs allege generally that the defendants violated the federal securities laws by, among other things, making material misstatements or omissions concerning our Phase 2 and Phase 3 clinical trials of Lonidamine
(TH-070).&nbsp;On&nbsp;November&nbsp;14, 2008, Defendants moved to dismiss the second consolidated amended complaint. On April&nbsp;3, 2009, the Court granted in part and denied in part the motions to dismiss, dismissing with prejudice all claims
arising under the Securities Act and all claims against Ms.&nbsp;Swearson, while narrowing the remaining claims. On October&nbsp;30, 2009, the parties entered into a stipulation&nbsp;of settlement to resolve the lawsuit.&nbsp;The settlement provides
for a payment&nbsp;to the plaintiff class solely by our insurers.&nbsp;On December&nbsp;1, 2009, the Court entered an order granting preliminary approval of the proposed settlement.&nbsp;The settlement is subject to final approval by the Court, and
a hearing at which the Court will consider whether to grant final approval of the settlement is scheduled for April&nbsp;15, 2010.&nbsp;However, we cannot provide any assurance that this hearing will not be rescheduled or that&nbsp;the settlement
will&nbsp;receive final Court approval. The defendants, including us, have denied and continue to deny all of plaintiffs&#146; allegations of wrongdoing.&nbsp;There can be no assurance&nbsp;at this time that the settlement&nbsp;process
will&nbsp;result in final Court approval.&nbsp;To the extent the case does not finally resolve through settlement, the defendants&nbsp;to the lawsuit, including us, continue to believe that the plaintiffs&#146; claims are without merit and intend to
defend against the actions vigorously. </FONT></P> <P STYLE="font-size:18px;margin-top:0px;margin-bottom:0px">&nbsp;</P>

biotechnology company focused on the discovery and development of drugs targeting the microenvironment of solid tumors as novel treatments for patients living with cancer. The microenvironment of solid tumors is characterized by, among other things,
hypoxia or lack of oxygen, disordered blood vessel growth, and the upregulation of glucose transport. This hypoxic environment is known to be resistant to standard chemotherapy and radiation. It is thought to be responsible for the poor prognosis of
many solid tumors and treating the hypoxic environment is currently believed to be a significant unmet medical need. Our product candidates are designed to selectively target the hypoxic microenvironment of tumors either by selective toxin
activation in the case of our hypoxia activated prodrug (HAP) program, including TH-302, or potentially utilizing the consequences of increased uptake of glucose in cancer cells relative to most normal cells. Our product candidates 2DG and the
recently out-licensed product candidate glufosfamide share certain structural characteristics with glucose but act instead as chemotherapeutic toxins when taken up by a cell. </FONT></P> <P

activated under the severe hypoxic conditions and was designed to specifically target the severe hypoxic regions that are present in most solid tumors. TH-302 is currently in Phase 1 and Phase 1/2 clinical trials. In 2009 and first quarter of 2010,
we reported results from the dose escalation component and dose expansion components in metastatic melanoma and small-cell lung cancer (SCLC) of the monotherapy Phase 1 trial and interim results from each of the four chemotherapy plus TH-302
treatments Phase 1/2 combination trials. We presented top-line results from the monotherapy and combination therapy trials in the first quarter of 2010 and expect to present updated top-line results from the monotherapy and combination therapy

On September&nbsp;5, 2008, the NASDAQ Stock Market notified us that we had regained compliance with the minimum bid price. Even though we regained compliance with the minimum bid price requirement, we cannot be assured that we will be able to
maintain compliance with the minimum bid price requirement in the future, and our failure to do so could result in the delisting of our shares from the NASDAQ Capital Market. To maintain our listing on the NASDAQ Capital Market, we are also
required, among other things, to either maintain stockholders&#146; equity of at least $5 million or a market value of at least $15 million. While we currently satisfy the stockholders&#146; equity requirement, we may not continue to do so. On
October&nbsp;16, 2008, the NASDAQ Stock Market suspended the enforcement of the minimum bid price and market value requirements through January&nbsp;16, 2009 and on December&nbsp;19, 2008, the suspension period was extended to April&nbsp;20, 2009.
The suspension period was subsequently extended to July&nbsp;31, 2009. NASDAQ&#146;s enforcement of these rules resumed on August&nbsp;3, 2009 and NASDAQ does not expect any further extensions of the suspension period. </FONT></P> <P

implementing ASC 718 including expected stock price volatility, expected life and estimated forfeitures of each award. The fair value of equity-based awards is amortized over the vesting period of the award, and we have elected to use the
straight-line method of amortization. Due to the limited amount of historical data available to us, particularly with respect to stock-price volatility, employee exercise patterns and forfeitures, actual results could differ from our assumptions.

in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, a reporting entity should disclose separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than
one net number). The updated guidance also requires that an entity should provide fair value measurement disclosures for each class of assets and liabilities and disclosures about the valuation techniques and inputs used to measure fair value for

statements are the responsibility of the Company&#146;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 the standards of the
Public Company Accounting Oversight Board (United States). 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, 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 our opinion. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">As discussed in Note 8 to the

disclosures, which requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and to describe the reasons for the transfers. In addition, in the reconciliation
for fair value measurements using significant unobservable inputs, or Level 3, a reporting entity should disclose separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than one net number). The
updated guidance also requires that an entity should provide fair value measurement disclosures for each class of assets and liabilities and disclosures about the valuation techniques and inputs used to measure fair value for both recurring and
non-recurring fair value measurements for Level 2 and Level 3 fair value measurements. The updated guidance is effective for interim or annual financial reporting periods beginning after December&nbsp;15, 2009, except for the disclosures about
purchases, sales, issuances, and settlements in the roll forward activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December&nbsp;15, 2010 and for interim periods within those fiscal years. The Company
does not expect adoption of the updated guidance to have a material impact on its consolidated results of operations or financial conditions. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman"

GAAP, and expands disclosures about fair value measurements and was adopted by the Company in the first quarter of 2008. In February 2008, the FASB issued new guidance now codified in ASC 820
which delays the effective date for non-financial assets and liabilities that are not measured or disclosed on a recurring basis to fiscal years beginning after November&nbsp;15, 2008 and was adopted by the Company in the first quarter of 2009.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit
price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the
use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: </FONT></P> <P

markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.&nbsp;The Company&#146;s short-term investments primarily utilize broker
quotes in a non-active market for valuation of these securities.</FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px; margin-left:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2"><I>Level 3</I> - Unobservable inputs that are supported by

the market approach to measure fair value for its financial assets.&nbsp;The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The following table sets forth the

September&nbsp;14, 2007, these lawsuits, which have been&nbsp;consolidated by the Court into a single proceeding,&nbsp;were ordered transferred to the United States District Court for the Northern District of California.&nbsp;On January&nbsp;15,
2008, Plaintiffs filed a first consolidated amended complaint. On July&nbsp;11, 2008, the Court granted Defendants&#146; motions to dismiss that complaint but afforded Plaintiffs leave to file a further amended complaint. On September&nbsp;19, 2008,
Plaintiffs filed a second consolidated amended complaint, which, on behalf of an alleged class of purchasers of our common stock from the date of our initial public offering of securities on February&nbsp;4, 2005 through July&nbsp;14,
2006,&nbsp;purports to allege claims arising under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, as amended (the &#147;Act&#148;), and under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the
&#147;Exchange Act&#148;). On November&nbsp;14, 2008, Defendants moved to dismiss the second consolidated amended complaint. On April&nbsp;3, 2009, the Court granted in part and denied in part the motions to dismiss, dismissing with prejudice all
claims arising under the Securities Act and all claims against Ms.&nbsp;Swearson, while narrowing the remaining claims. On October&nbsp;30, 2009, the parties entered into a stipulation&nbsp;of settlement to resolve the lawsuit.&nbsp;The settlement
provides for a payment&nbsp;of $10.0 million to the plaintiff class solely by the Company&#146;s insurers.&nbsp;On December&nbsp;1, 2009, the Court entered an order granting preliminary approval of the proposed settlement.&nbsp;The settlement is
subject to final approval by the Court, and a hearing at which the Court will consider whether to grant final approval of the settlement is scheduled for April&nbsp;15, 2010.&nbsp;The defendants, including the Company, have denied and continue to
deny all of plaintiffs&#146; allegations of wrongdoing.&nbsp;There can be no assurance&nbsp;at this time that the settlement&nbsp;process will&nbsp;result in final Court approval.&nbsp;To the extent the case does not finally resolve through

preferred stock purchase rights (&#147;the rights&#148;) were distributed to stockholders of record as of August&nbsp;23, 2006, at the rate of one right for each share of common stock held. The rights become exercisable only upon the acquisition, or
the acquisition of the right to acquire, by a person or group of affiliated or associated persons, 15% or more of the outstanding shares of the Company&#146;s common stock. Once exercisable, each right entitles the holder to purchase, at a price of
$25.00, one one-thousandth of a share of Series A Participating Preferred Stock. For a limited period of time following the announcement of any such acquisition or offer, the rights are redeemable by the Company at a price of $0.01 per right. If the
rights are not redeemed or exchanged, each right will then entitle the holder to receive, upon exercise of such right, a number of shares of the Company&#146;s common stock having a then current value equal to two times the purchase price of such
right. Similarly, if the rights are not redeemed or exchanged and following the acquisition of 15% or more of the outstanding shares of the Company&#146;s common stock by a person or group of affiliated or associated persons, (i)&nbsp;the Company
consolidates with or merges into another entity, (ii)&nbsp;another entity consolidates with or merges into the Company or (iii)&nbsp;the Company sells or otherwise transfers 50% or more of its consolidated assets or earning power, each right will
then entitle the holder to receive, upon exercise of such right, a number of shares of common stock of the acquiring company having a then current value equal to two times the purchase price. For a limited period of time after the exercisability of
the rights, each right, at the discretion of the Board of Directors, may be exchanged for one share of common stock per right. The Company has initially reserved 200,000 shares of preferred stock pursuant to the exercise of these rights. These

determine the expected term of the Company&#146;s employee stock options granted during the years ended December&nbsp;31, 2009, 2008 and 2007, the Company utilized the simplified approach as defined by SEC Staff Accounting Bulletin No.&nbsp;107,
<B><I></I></B><I>&#147;Share-Based Payment&#148;</I><B><I></I></B> (&#147;SAB 107&#148;). To determine the risk-free interest rate, the Company utilized an average interest rate based on U.S. Treasury instruments with a term consistent with the
expected term of the Company&#146;s awards. To determine the expected stock price volatility for the Company&#146;s stock options for the years ended December&nbsp;31, 2008, 2007 and 2006, the Company examined historical volatilities for industry
peers as the Company did not have sufficient trading history for its common stock and utilized a median of the historical volatilities of the Company&#146;s industry peers. The Company will continue to analyze the expected stock price volatility and
expected term assumption as more historical data for the Company&#146;s common stock becomes available. The expected stock price volatility for the Company&#146;s ESPP for the years ended December&nbsp;31, 2009, 2008 and 2007 was based on expected
stock price volatilities of the Company&#146;s industry peers, as well as the historical volatility of the Company&#146;s common stock as the Company had trading history for its common stock in excess of the expected term of the stock purchase
rights under the ESPP. The fair value of all the Company&#146;s stock based award assumes no dividends as the Company does not anticipate paying cash dividends on its common stock. <B><I> </I></B></FONT></P> <P

prices below the fair market value of the Company&#146;s common stock at the date of grant, determined with hindsight. In accordance with the requirements of ASC 718, the Company has recorded deferred stock-based compensation for the difference

Through December&nbsp;31, 2009, the Company had amortized the entire $19.5 million as compensation expense, net of forfeitures, with approximately $6,000, $0.8 million and $2.8 million being amortized for the years ended December&nbsp;31, 2009, 2008

income or tax liabilities. For federal and state income tax purposes, a portion of the Company&#146;s net operating loss carryforward is subject to certain limitations on annual utilization in case of changes in ownership, as defined by federal and
state tax laws. The annual limitation may result in the expiration of the net operating loss before utilization. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">At
December&nbsp;31, 2009, the Company had state research and development tax credits of approximately $2.8 million, which have no expiration date. During the year ended December 31, 2009, the Company wrote down its deferred tax assets related to net
