NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)



|1. | The Company
|-- | -----------

Cadence Pharmaceuticals, Inc. (the Company) was incorporated in the state of Delaware in May 2004. The Company is a biopharmaceutical company focused on in-licensing, developing and commercializing proprietary product candidates
principally for use in the hospital setting. The Companys primary activities since incorporation have been conducting research and development activities, including clinical trials, of its product portfolio; organizational activities,
including recruiting personnel, establishing office facilities; and raising capital to fund these activities. To date, the Company has in-licensed rights to Acetavance, formerly known as IV APAP, which is an intravenous formulation of
acetaminophen, and Omigard, an omiganan pentahydrochloride 1% aqueous gel, both of which are product candidates currently being studied in Phase III clinical trials. Since the Company has not begun principal operations of commercializing
either of its product candidates, the Company is considered to be a development stage company as defined in Statement of Financial Accounting Standards (SFAS) No. 7, Accounting and Reporting by Development Stage Enterprises.



|2. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Reclassifications

Where necessary, prior period amounts have been
reclassified to conform to current period presentation. These reclassifications had no effect on net loss or stockholders equity as previously reported.

Basis of Presentation

The Company has prepared the accompanying unaudited
condensed financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP). However, certain information and disclosures normally included in financial statements prepared in
accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In addition, the preparation of financial statements in conformity with GAAP requires
management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. In the opinion of the Companys management, all adjustments consisting of normal, recurring adjustments considered
necessary for a fair presentation of the results of the interim periods presented have been included. These condensed financial statements should be read in conjunction with the audited financial statements of the Company for the fiscal year ended
December 31, 2007, as included in the Companys 2007 Annual Report on Form 10-K as filed with the SEC on March 13, 2008.

Stock-Based Compensation

SFAS No. 123(R),Share-Based Payment, requires companies
to estimate the fair value of stock-based payment award on the date of grant using an option pricing model. The Company currently uses the Black-Scholes option pricing model to estimate the fair value of its stock-based awards. This option pricing
model involves a number of estimates, including the expected lives of stock options, the Companys anticipated stock volatility and interest rates. Stock-based compensation expense recognized during the period is based on the value of the
portion of awards that is ultimately expected to vest and thus the gross expense is reduced for estimated forfeitures. Compensation expense for all stock-based payment awards was recognized using the straight-line method. The following table
summarizes the average estimates the Company used in the Black-Scholes option-pricing model during the three months ended March 31, 2008 and 2007, to determine the fair value of employee stock options granted during each period:

Fair Value Reporting

Effective January 1, 2008, the Company adopted the provisions of SFAS No. 157, Fair Value Measurement. SFAS No. 157
defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements, but does not require any new fair value measurements. SFAS No. 157s valuation techniques
are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect market assumptions. SFAS No. 157 classifies these inputs into the following fair
value hierarchy:



|               |  |   |  |                                                                                                                                                                                                                                                       
|-------------- |  | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 Inputs |  |  |  | Quoted prices for identical instruments in active markets.                                                                                                                                                                                            
|               |  |  
|Level 2 Inputs |  |  |  | Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant
inputs and significant value drivers are observable.
|               |  |  
|Level 3 Inputs |  |  |  | Valuation derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

|3. | Recent Accounting Pronouncements
|-- | --------------------------------

In March 2008, the Financial Accounting Standards Board (FASB) issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activitiesan amendment of FASB Statement
No. 133. SFAS No. 161 amends SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, and intends to improve financial reporting about derivative instruments and hedging activities by requiring enhanced
disclosures to enable investors to better understand their effects on an entitys financial position, financial performance, and cash flows. SFAS No. 161 also requires disclosure about an entitys strategy and objectives for using
derivatives, the fair values of derivative instruments and their related gains and losses. SFAS No. 161 is effective for reporting periods beginning after November 15, 2008, with early adoption encouraged. The Company is currently
reviewing the effects of SFAS No. 161; however, the adoption is not expected to have a material impact as the Company does not currently hold derivative instruments.

Effective January 1, 2008, the Company adopted Emerging Issues Task Force (EITF) Issue No. 07-03,Accounting for Nonrefundable Advance Payments for Goods or Services to
Be Used in Future Research and Development Activities. EITF No. 07-03 provides that nonrefundable advance payments for goods that will be used, or services that will be performed in future research and development activities, should be
deferred and capitalized until the goods have been delivered or the related services have been rendered. The adoption of EITF No. 07-03 did not have a material impact on the Companys financial position, cash flow or results of operations.

Also effective January 1, 2008, the Company adopted SFAS No. 159, The Fair Value Option for Financial Assets
and Financial Liabilities. SFAS No. 159 allows entities to account for most financial instruments at fair value rather than under other applicable generally accepted accounting principles, such as historical cost. The accounting
results in the instrument being marked to fair value every reporting period with the gain/loss from a change in fair value recorded in the income statement. The adoption of SFAS No. 159 did not have a material impact on the Companys
financial position, cash flow or results of operations.



|4. | Net Loss Per Share
|-- | ------------------

Net loss per share is presented as basic and diluted net loss per share. Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding for the period, without consideration for
common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common share equivalents outstanding for the period determined using the treasury-stock method. For purposes of this
calculation, stock options and warrants are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The actual net loss per share amounts for the three months ended March 31, 2008
and 2007 were computed based on the shares of common stock outstanding during the respective periods. The net loss per share for the three months ended March 31, 2008 includes the effect of the 9,240,307 common shares issued by the Company in
the first quarter of 2008 pursuant to an effective shelf registration. As a result of the issuance of these common shares, there is a lack of comparability in the basic and diluted net loss per share amounts for the three month periods ended
March 31, 2008 and 2007.

The following is a reconciliation of the basic and diluted shares for the periods presented:



|                                                              |  |                             |   |  |            |

For the three months ended March 31, 2008 and 2007, options and other
exercisable convertible securities totaling 3,011,331 and 2,677,320 shares, respectively, were excluded from the calculation as their effect would have been antidilutive.



|5. | Comprehensive Loss
|-- | ------------------

The Company has applied SFAS No. 130,Reporting Comprehensive Income, which requires that all components of comprehensive income, including net income, be reported in the financial statements in the period in which they are
recognized. Comprehensive income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net income and other comprehensive income, including foreign currency translation
adjustments and unrealized gains and losses on investments, are reported, net of their related tax effect, to arrive at comprehensive income. The components of other comprehensive loss for the periods presented were as follows:

|7. | Loan and Security Agreement
|-- | ---------------------------

In February 2006, the Company entered into a $7,000,000 Loan and Security Agreement (the Agreement) with Silicon Valley Bank and Oxford Finance Corporation to provide growth capital to the Company. In June
2006, the Company drew down $7,000,000 under the Agreement at a fixed interest rate of 11.47%. In November 2007, the Company amended the Agreement and entered into the Second Amendment to Loan and Security Agreement (the Second
Amendment) with the same parties and GE Business Financial Services Inc. (formerly known as Merrill Lynch Business Financial Services Inc.), to secure an additional $15,000,000 credit facility. In December 2007, the Company drew down
$15,000,000 under the Second Amendment in two separate draws of $5,000,000 and $10,000,000 with fixed interest rates of 7.83% and 7.74%, respectively, net of a $45,000 loan fee (the loan fee). In addition to the principal and interest,
the Company is required to pay $375,000 at the termination of the credit facility (the term loan final payment). The loan fee and the warrants issued in connection with the loan (as described below), have been recognized as a discount on
the loan issuance which, together with the fixed interest rates, will be amortized to interest expense throughout the life of the loan using an effective interest rate of 9.56%. The term loan payment is being accrued through interest expense over
the life of the loan. All interest payable under the Second Amendment and the full amount of the term loan final payment must be paid upon any prepayment of the loan.

The loans are collateralized by substantially all the assets of the Company (excluding intellectual property). Under the terms of the Agreement, the Company may be precluded from entering into
certain financing and other transactions, including disposing of certain assets and paying dividends, and is subject to certain non-financial covenants and prepayment penalties. Upon the occurrence of an event of default, including a Material
Adverse Change (as defined in the Agreement), the lenders may declare all outstanding amounts due and payable under the Agreement.

In August 2006, the Company began making the first of six interest-only payments on the $7,000,000 balance of the Agreement and in February 2007, began making the first of 30 equal principal and interest payments. In January 2008, the
Company began making the first of six interest-only payments on the $15,000,000 balance of the Second Amendment and thereafter will make 30 equal monthly principal and interest payments to fully amortize the balance. At the termination of the
$15,000,000 credit facility, the Company will also pay the $375,000 term loan final payment.

As of March 31, 2008 and
December 31, 2007, the aggregate principal balance of the loans, net of the loan discount, included on the Companys condensed balance sheets was $18,436,036 and $19,030,277, respectively.

Warrants

In connection with the Agreement with Silicon Valley Bank and Oxford Finance Corporation, the Company issued two fully exercisable warrants to the lenders to purchase an aggregate of
385,000 shares of the Companys Series A-2 preferred stock at an exercise price of $1.00 per share. These warrants became exercisable for 96,250 shares of the Companys common stock, at an exercise price of
$4.00 per share, upon the completion of the Companys initial public offering in October 2006. The $313,572 fair value of the warrants was determined using the Black-Scholes valuation model, recorded as a discount to the note payable, and
amortized to interest expense over the expected term of the loan agreement. The warrants were valued using the following assumptions: risk-free interest rate of 4.57%; dividend yield of 0.0%; expected volatility of 70.0%; and a contractual term of
10 years. In November 2006, one warrant was exercised for 48,125 shares of the Companys common stock at a price of $9.45, resulting in 27,754 shares issued on a net exercise basis. In March 2007, the remaining warrant was exercised for
48,125 shares of the Companys common stock at a price of $15.04, resulting in 35,325 shares issued on a net exercise basis.

In connection with the Second Amendment to the Agreement with Silicon Valley Bank, Oxford Finance Corporation and GE Business Financial Services Inc., the Company issued six fully exercisable warrants to the lenders to purchase an aggregate
of 50,331 shares of the Companys common stock at an exercise price of $12.67 per share. The Company determined the fair value of these warrants to be $473,876, using the Black-Scholes valuation model. The value of the warrants were
recorded as a discount to the note payable, and will be amortized to interest expense over the expected term of the loan agreement. The warrants were valued using the following assumptions: risk-free interest rate of 3.64%; dividend yield of 0.0%;
expected volatility of 70.0%; and a contractual term of 7 years. As of March 31, 2008, all warrants related to the Second Amendment were outstanding.



|8. | Commitments and Contingencies
|-- | -----------------------------

Leases

In May 2006, the Company entered into a six-year operating lease for 23,494 square feet
of office space. The Company received certain tenant improvement allowances and rent abatement and has an option to extend the lease for five years following the expiration of the initial term. Monthly rental payments are adjusted on an annual basis
and the lease expires in September 2012. As security for the lease, a letter of credit in the initial amount of $1,581,130 was required by the landlord. The letter of credit is collateralized by a certificate of deposit in the same amount that is
classified as restricted cash in the Companys balance sheet. The required amount subject to the letter of credit and corresponding certificate of deposit may be reduced by 22% on each of the first four anniversaries of the commencement of the
lease. During the fourth quarter of 2007, the letter of credit was reduced by $347,848 in accordance with the agreement and the related restricted cash was adjusted by a like amount.

In January 2007, the Company entered into a sublease agreement for a portion of its unused office space, to be in effect through the
third quarter of 2009. Rent expense, net of sublease rent income, for the three months ended March 31, 2008 and 2007 was $138,244 and $163,006, respectively. Since May 26, 2004 (inception) through March 31, 2008, the Company has
incurred net rent expense of $1,716,112.

Supply Agreement

On July 18, 2007, the Company entered into a development and supply agreement with Baxter Healthcare Corporation
(Baxter) for the completion of pre-commercialization manufacturing development activities and the manufacture of commercial supplies of the finished drug product for Acetavance. Pursuant to the terms of the agreement with Baxter, Baxter
will receive development fees from the Company upon the completion of specified development activities, which the Company will expense as the costs are incurred. In addition, Baxter will receive a set manufacturing fee based on the amount of the
finished Acetavance drug product produced, which prices may be adjusted by Baxter, subject to specified limitations. The Company is also obligated to purchase a minimum number

of units each year following regulatory approval, or pay Baxter an amount equal to the per-unit purchase price multiplied by the amount of the shortfall.
Further, the Company is obligated to reimburse Baxter for all reasonable costs directly related to work performed by Baxter in support of any change in the active pharmaceutical ingredient (API) source or API manufacturing process.

The agreement with Baxter also requires the Company to fund specified improvements at Baxters manufacturing facility
and purchase certain equipment for use by Baxter in manufacturing Acetavance. The Company will reimburse Baxter for the facility improvements and expense these costs as incurred. The equipment purchased for the manufacturing of Acetavance to which
the Company retains title will be capitalized and amortized over the life of the equipment. At the time of termination, the agreement requires the Company to reimburse Baxter for all reasonable costs for de-installation of the Companys
equipment and the restoration of Baxters manufacturing facility to its pre-installation condition. The Company is not able to reasonably estimate the cost and the timing of these expenses at this time and therefore cannot reasonably estimate
the fair value of the retirement obligation.

In anticipation of the execution of the agreement with Baxter, the Company
entered into an irrevocable standby letter of credit in favor of Baxter in January 2007. The letter of credit was for an initial amount of $3,268,000 and was based on anticipated costs to be incurred by Baxter for the improvements at Baxters
manufacturing facility and the purchase of equipment to be used by Baxter in the manufacturing of the finished drug product. Under the terms of the agreement, the amount of the letter of credit may be reduced quarterly following the execution of the
agreement for the costs the Company has reimbursed Baxter to fund the specified facility improvements or equipment purchases. In December 2007, at the request of the Company and based upon the costs reimbursed to Baxter by the Company, the letter of
credit was reduced by $768,000 to $2,500,000. The letter of credit in favor of Baxter is collateralized by a certificate of deposit in the amount of $1,634,000 and may be drawn down in part or in whole by Baxter in the event the Company fails to
perform its obligations to fund the specified facility improvements or equipment purchases.

License Agreements and Acquired
Development and Commercialization Rights

In July 2004, the Company in-licensed from Migenix, Inc.
(Migenix) the technology and the exclusive development and commercialization rights to its omiganan pentahydrochloride product candidate for the prevention and treatment of device-related, wound-related, and burn-related infections in
North America and Europe. At the time the agreement was executed, the Company paid a $2,000,000 up-front fee, of which $1,550,000 was allocated to the value of the acquired technology and $450,000 was recorded as other long-term assets in the
accompanying condensed balance sheet for the 617,284 shares of Migenix common stock acquired in the transaction. The Company may also be required to make future milestone payments totaling up to $27,000,000 upon the achievement of various
milestones related to regulatory or commercial events. In addition, the Company is obligated to pay a royalty on future net sales (as defined in the Migenix collaboration and license agreement) of the licensed products and has the right to grant
sublicenses to affiliates. All payments related to the Migenix agreement (other than for the acquisition of common stock) have been recognized as research and development expense.

In March 2006, the Company in-licensed the technology and the exclusive development and commercialization rights to its Acetavance
product candidate in the U.S. and Canada from Bristol-Myers Squibb Company (BMS). BMS sublicensed these rights to the Company under a license agreement with SCR Pharmatop S.A. As consideration for the license, the Company paid a
$25,000,000 up-front fee, and may be required to make future milestone payments totaling up to $40,000,000 upon the achievement of various milestones related to regulatory or commercial events. In addition, the Company is obligated to pay a royalty
on net sales of the licensed products and has the right to grant sublicenses to third parties. All payments related to the BMS agreement have been recognized as research and development expense.

|-- | --------------------

Shelf Registration

On November 30, 2007, the Company filed a shelf registration statement that
was declared effective by the SEC on December 11, 2007. This shelf registration statement allows the Company to sell shares of its common stock from time to time in one or more offerings, with an aggregate offering price of up to $100,000,000.
In February 2008, the Company issued 9,240,307 shares of its common stock at a purchase price of $5.34 per share pursuant to the shelf registration. The registered direct offering raised proceeds, net of offering costs, of $49,139,017. The
purchasers in the offering were comprised of new investors and existing stockholders, including executive officers and directors of the Company.



|10. | Income Taxes
|--- | ------------

The Company is subject to taxation in the U.S. and various state jurisdictions. The Companys tax years for 2004 and forward are subject to examination by the Federal and California tax authorities due to the carryforward of unutilized
net operating losses and research and development credits. The Companys practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrued interest and/or penalties related to
income tax matters in the Companys condensed balance sheets at March 31, 2008 or December 31, 2007, and has recognized no interest and/or penalties in the Companys condensed statement of operations for the three months ended
March 31, 2008 and 2007, respectively.

The Company adopted the provisions of FASB Interpretation (FIN)
48, Accounting for Income Tax Uncertainties, on January 1, 2007. On the date of adoption of FIN No. 48, there were no unrecognized tax benefits and thus the Company did not recognize an increase in the liability for unrecognized tax
benefits. Further, there are no unrecognized tax benefits included in the Companys condensed balance sheet at March 31, 2008 or December 31, 2007, respectively.

Item 2.Managements Discussion and Analysis of Financial Condition and Results of Operations

Introduction

The following discussion contains forward-looking statements, which
involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth below under the caption Risk Factors. The
interim financial statements and this Managements Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the financial statements and notes thereto for the year ended December 31, 2007
and the related Managements Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our Annual Report on Form 10-K for the year ended December 31, 2007.

Overview

We are a biopharmaceutical company focused on in-licensing, developing and commercializing proprietary product candidates principally for use in the hospital setting. Since our inception in May 2004, we have
in-licensed rights to two product candidates, both of which are currently being studied in Phase III clinical trials. We have in-licensed the exclusive U.S. and Canadian rights to Acetavance, formerly known as IV APAP, an intravenous
formulation of acetaminophen that is currently marketed in Europe and several other markets by Bristol-Myers Squibb Company, or BMS, for the treatment of acute pain and fever under the brand name Perfalgan®. We have also in-licensed the exclusive North American and European rights to omiganan pentahydrochloride 1% aqueous gel, or OmigardTM, for the prevention and treatment of device-related, surgical wound-related and burn-related infections. We believe that the hospital setting is a concentrated, underserved market for pharmaceuticals and anticipate
building our own, hospital-focused sales force as our product candidates approach potential U.S. Food and Drug Administration, or FDA, approval. We intend to build a leading franchise in the hospital setting, continuing to focus on products
that are in late stages of development, currently commercialized outside the U.S., or approved in the U.S. but with significant commercial potential for proprietary new uses or formulations.

We were incorporated under the laws of the State of Delaware in May 2004. Our principal executive offices are located at 12481 High Bluff
Drive, Suite 200, San Diego, California 92130 and our telephone number is (858) 436-1400. Information about the company is also available at our website at www.cadencepharm.com, which includes links to reports we have filed with the Securities
and Exchange Commission, or SEC. The contents of our website are not incorporated by reference in this Quarterly Report on Form 10-Q.

Background

We were incorporated in May 2004 and during that year we focused on hiring our management team
and initial operating employees and on in-licensing our first product candidate, Omigard. Substantial operations did not commence until September 2004. During 2005, we completed the special protocol assessment, or SPA, for Omigard, and initiated
Phase III clinical trials for this product candidate. In March 2006, we in-licensed rights to Acetavance from BMS and in October 2006, we initiated our Phase III clinical development program for Acetavance. During 2007, we continued
our Phase III clinical development programs for our product candidates. We completed enrollment in our Phase III clinical trial of Omigard in April 2008 and, if the results of the trial are positive, we expect to submit a new drug application, or
NDA, to the FDA for Omigard in the first half of 2009. In January 2008, we announced top-line results from two Phase III clinical trials of Acetavance for the treatment of pain and fever, and in May 2008, we announced the results of a second Phase
III clinical trial of Acetavance for the treatment of fever in adults. Assuming successful completion of our other planned clinical trials for this product candidate, we currently plan to submit a 505(b)(2) NDA for Acetavance to the FDA in the first
half of 2009.

We are a development stage company and we have incurred significant net losses since our inception. As of
March 31, 2008, we had an accumulated deficit of $128.1 million. These losses have resulted principally from costs incurred in connection with research and development activities, including license fees, costs of clinical trial activities
associated with our current product candidates and general and administrative expenses. We expect to continue to incur operating losses for the next several years as we pursue the clinical development and market launch of our product candidates and
acquire or in-license additional products, technologies or businesses that are complementary to our own.

##### Table of Contents

In October 2006, we completed an initial public offering in which we sold
6.0 million shares of our common stock at $9.00 per share and received aggregate net proceeds of $48.4 million (after underwriting discounts and offering costs). In November 2006, following exercise of the underwriters
over-allotment option, we sold 0.9 million shares of our common stock at $9.00 per share and received aggregate net proceeds of $7.5 million (after underwriting discounts). In February 2008, we completed a registered direct offering
pursuant to an effective shelf registration statement under which we issued and sold 9.2 million shares of common stock at $5.34 per share and received aggregate net proceeds of approximately $49.1 million (after offering costs).

Revenues

We
have not generated any revenues to date, and we do not expect to generate any revenues from licensing, achievement of milestones or product sales until we are able to commercialize our product candidates ourselves or execute a collaboration

Our research and development expenses consist primarily of license fees, salaries and related employee benefits, costs associated with
clinical trials managed by our contract research organizations, or CROs, costs associated with non-clinical activities, such as regulatory expenses, and pre-commercialization manufacturing development activities. Our most significant costs are for
clinical trials and license fees. The clinical trial expenses include payments to vendors such as CROs, investigators, clinical suppliers and related consultants. License fees are paid to the patent holders of our product candidates that give us the
exclusive licenses to the patent rights and know-how for selected indications and territories. We may be required to make future milestone payments totaling up to $67.0 million for our product candidates.

Our historical research and development expenses relate predominantly to the in-licensing of Acetavance and Omigard and the related
clinical trials for these product candidates. We expense all research and development charges as they are incurred as the underlying technology associated with these expenditures relates to our research and development efforts and has no alternative
future uses. We use external service providers and vendors to conduct our clinical trials, to manufacture our product candidates to be used in clinical trials and to provide various other research and development related products and services. A
substantial portion of these external costs are tracked on a project basis. Our internal research and development resources are used in several projects and may not be attributable to a specific product candidate. For example, a substantial portion
of our internal costs, including personnel and facility related costs, are not tracked on a project basis.

The following
table summarizes our research and development expenses included in our condensed statements of operations for the three months ended March 31, 2008 and 2007, and for the period from May 26, 2004 (inception) through March 31, 2008.
Costs that are not attributable to a specific product candidate, including salaries and related personnel costs, are included in the other supporting costs category (in thousands):

At this time, due to the risks inherent in the clinical trial process and given
the early stage of our product development programs, we are unable to estimate with any certainty the costs we will incur in the continued development of our product candidates for potential commercialization. Clinical development timelines, the
probability of success and development costs vary widely. While we are currently focused on advancing each of our product development programs, our future research and development expenses will depend on the determinations we make as to the
scientific and clinical success of each product candidate, as well as ongoing assessments as to each



13

##### Table of Contents

product candidates commercial potential. In addition, we cannot forecast with any degree of certainty which product candidates will be subject to
future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

We expect our development expenses to be substantial over the next few years as we continue the advancement of our product development programs. We initiated our Phase III clinical trial for
Omigard in August 2005 and completed enrollment in the study in April 2008. The current clinical development program for Acetavance includes three Phase III efficacy trials, two pharmacokinetic studies, two multi-day safety studies and a
placebo-controlled, 48-hour safety trial, as well as other supportive studies conducted by Cadence, BMS or reported in scientific and medical literature. In January 2008, we announced that our Phase III efficacy trial of Acetavance for the
treatment of pain in adults following abdominal gynecological surgery did not meet its primary endpoint of demonstrating a statistically significant reduction in patients pain intensity scores over 48 hours compared to placebo. Also in January
2008, we announced that our Phase III clinical trial of Acetavance in fever successfully met the primary endpoint, demonstrating a statistically significant reduction of fever over six hours compared to placebo. Following the announcement of these
results, we initiated communications with the FDA to seek additional guidance from the agency regarding our development program for this product candidate. As a result of our communications with the FDA, the agency may require or we may decide to
conduct additional clinical trials or to modify our ongoing clinical trials, which would increase our costs and may delay, or limit the scope of, any regulatory approvals for this product candidate. In May 2008, we announced that our second Phase
III clinical trial of Acetavance for the treatment of fever in adults successfully met the primary endpoint, demonstrating a statistically significant more rapid onset of action for the treatment of experimentally-induced fever as compared to the
same dose of orally-administered acetaminophen. Assuming successful completion of all of our planned clinical trials for this product candidate, we currently plan to submit a 505(b)(2) NDA for Acetavance to the FDA in the first half of 2009. Our
failure to achieve our product development goals for Acetavance in a timely manner, or at all, could adversely affect our business and our stock price.

Marketing

Our marketing expenses consist primarily of market research
studies, salaries, benefits and professional fees related to building our marketing capabilities. We anticipate substantial increases in marketing expenses as we continue to develop and prepare for the potential commercialization of our product
candidates, including the addition of marketing and hospital-focused sales personnel to market our products to physicians, nurses, hospitals, group purchasing organizations and third-party payors.

General and Administrative

Our general and administrative expenses consist primarily of salaries, benefits and professional fees related to our administrative, finance, human resources, legal, business development and internal systems support
functions, as well as insurance and facility costs. We anticipate increases in general and administrative expenses as we continue to build our corporate infrastructure in support of our continued development and preparation for the potential
commercialization of our product candidates.

Interest and Other Income and Expense

Our interest income consists primarily of interest earned on our cash, cash equivalents and short-term investments. Interest expense is
primarily the interest we have incurred under our amended loan and security agreement. Other expense includes charges we have incurred to recognize other-than-temporary declines in the market value of our available-for-sale securities, losses we
have recognized on the disposal of equipment and the gains or losses recognized on transactions denominated in foreign currencies.

Income Taxes

We adopted the provisions of Financial Accounting Standards Board, or FASB,
Interpretation No. 48,Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109, or FIN No. 48, on January 1, 2007. FIN No. 48 clarifies the accounting for uncertainty in income
taxes recognized in an entitys financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes, and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax
positions taken or expected to be taken on a tax return. Under FIN No. 48, the impact of an uncertain income tax position on the



14

##### Table of Contents

income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An
uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, FIN No. 48 provides guidance on derecognition, classification, interest and penalties, accounting in interim periods,
disclosure and transition.

As of January 1, 2008, we had both federal and state net operating loss carryforwards of
approximately $81.6 million. If not utilized, the net operating loss carryforwards will begin expiring in 2024 for federal purposes and 2014 for state purposes. Additionally, as of January 1, 2008, we had both federal and state research
and development tax credit carryforwards of approximately $1.5 million and $0.7 million, respectively. The federal tax credits will begin expiring in 2024 unless previously utilized and the state tax credits carryforward indefinitely. Under
Section 382/383 of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, substantial changes in our ownership may limit the amount of net operating loss carryforwards that could be utilized annually in the future to
offset taxable income and any such annual limitation may significantly reduce the utilization of the net operating losses before they expire. We have not completed a Section 382/383 study at this time regarding the limitation of net operating
loss and research and development credit carryforwards. Until this analysis has been completed, we have removed the deferred tax assets for net operating losses of approximately $33.3 million and research and development credits of approximately
$2.0 million and recorded a corresponding decrease to our valuation allowance. Once the analysis is completed, we plan to update our unrecognized tax benefits under FIN No. 48, however we do not expect this analysis to be completed within the
next 12 months and, as a result, we do not expect that the unrecognized tax benefits will change in the next 12 months. However, due to the existence of the valuation allowance, future changes in our unrecognized tax benefits will not impact our
effective tax rate.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S., or GAAP, requires us to make certain estimates, judgments and assumptions that
affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of expenses during the reporting period. Some of our accounting policies
require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. The following accounting policies involve critical accounting estimates because they are particularly
dependent on estimates and assumptions made by management about matters that are highly uncertain at the time the accounting estimates are made. In addition, while we have used our best estimates based on facts and circumstances available to us at
the time, different estimates reasonably could have been used. Changes in the accounting estimates we use are reasonably likely to occur from time to time, which may have a material impact on the presentation of our financial condition and results
of operations.

Our most critical accounting estimates include our recognition of research and development expenses, which
impacts operating expenses and accrued liabilities; and stock-based compensation which impacts operating expenses. We also have other policies that we consider to be key accounting policies, such as our policies for the assessment of recoverability
of long-lived assets; deferred income tax assets and liabilities; and our reserves for commitments and contingencies; however, these policies either do not meet the definition of critical accounting estimates described above or are not currently
material items in our financial statements. We review our estimates, judgments, and assumptions periodically and reflect the effects of revisions in the period in which they are deemed to be necessary. We believe that these estimates are reasonable;
however, actual results could differ from these estimates.

Research and Development Expenses

A substantial portion of our ongoing research and development activities is performed under agreements we enter into with external
service providers, including CROs, which conduct many of our research and development activities. We accrue for costs incurred under these contracts based on factors such as estimates of work performed, milestones achieved, patient enrollment and
experience with similar contracts. As actual costs become known, we adjust our accruals. To date, our accruals have been within managements estimates. Subsequent changes in estimates may result in a change in our accruals, which could also
materially affect our results of operations.

Stock-Based Compensation

We account for stock-based compensation under the provisions of Statement of Financial Accounting Standards, or SFAS, No. 123(R),
Share-Based Payment, which revises SFAS No. 123, Accounting for Stock-Based Compensation and supersedes Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock Issued to Employees. Under SFAS
No. 123(R), we calculate the fair value of our stock-based compensation awards to our employees and directors using the Black-Scholes pricing model. This model requires a number of estimates to be used in determining the fair value, including
the expected lives of awards, interest rates, stock volatility and other assumptions. A change in any of the estimates used in the model, or the selection of a different option pricing model, could have a material impact on our operations. Equity
instruments issued to non-employees are recorded at their fair value as determined in accordance with SFAS No. 123(R) and Emerging Issues Task Force 96-18, Accounting for Equity Instruments That are Issued to Other Than Employees for
Acquiring, or in Conjunction with Selling Goods and Services, and are periodically revalued as the equity instruments vest and are recognized as expense over the related service period.

The table below summarizes the stock-based compensation expense included in our condensed statements for the three months ended
March 31, 2008 and 2007, and for the period from May 26, 2004 (inception) through March 31, 2008 (in thousands):

As of March 31, 2008, the total future compensation expense related to the
current unvested stock options is expected to be approximately $14.5 million. This expense is expected to be recognized over a weighted average period of approximately 18 months.

Results of Operations

Three-Month Periods Ended March 31, 2008 and 2007

Operating expenses

Research and Development Expenses. Research and development expenses increased $2.3 million for the three months ended March 31, 2008 to $10.5 million, from $8.2 million for the comparable period during 2007. This
change was due to increased expenses for both of our product candidates, including $0.9 million from activities for Acetavance and $0.8 million from activities for Omigard. The increase in expenses for Acetavance was primarily related to the
pre-commercialization manufacturing development activities, combined with increased clinical trial activity. The increase in expenses for Omigard was primarily related to increased clinical trial activity, primarily in our CLIRS trial, which
completed enrollment in April 2008. Our other supporting costs for research and development activities increased $0.5 million during the three months ended March 31, 2008, as compared to the same period during 2007, primarily due to a $0.4
million increase in labor related costs (including a $0.2 million increase in stock-based compensation charges).

Marketing Expenses. Marketing expenses increased $0.3 million for the three months ended March 31, 2008 to $0.6 million, from $0.3 million for the comparable period during 2007. This increase was primarily due to
increased market research and related activities for Omigard, as well as increased salaries and related personnel costs.

##### Table of Contents

General and Administrative Expenses. General and administrative expenses
increased $0.8 million for the three months ended March 31, 2008, to $2.7 million, from $1.9 million for the comparable period during 2007. This increase was primarily due to increases in salaries and related personnel costs (including a $0.4
million increase in stock-based compensation charges).

Interest Income. Interest income decreased $0.5 million
for the three months ended March 31, 2008, to $0.5 million, from $1.0 million for the comparable period during 2007. This decrease was primarily due to a lower average cash and cash equivalent balance and a lower average yield earned on
our investments during the period in 2008 as compared to 2007.

Interest Expense. Interest expense increased
$0.3 million for the three months ended March 31, 2008 to $0.5 million, from $0.2 million for the comparable period during 2007. This increase is due to an amendment to our loan and security agreement in which we secured an additional $15.0
million in December 2007, made to us in two separate draws of $5.0 million and $10.0 million with fixed interest rates of 7.83% and 7.74%, respectively. At the time of the initial draw we received our funds net of loan fees of less than $0.1 million
and will be required to pay $0.4 million at the termination of the credit facility which, together with the loan fees, is being amortized to interest expense throughout the life of the loan. Additionally, in connection with the loan, we issued six
fully exercisable warrants to the lenders to purchase an aggregate of 50,331 shares of our common stock at an exercise price of $12.67 per share. We determined that the fair value of these warrants was $0.5 million, using the Black-Scholes pricing
model, which we accounted for as a debt discount and are amortizing to interest expense throughout the life of the loan. Partially offsetting the increase in interest expense from the $15.0 million credit facility was a reduction in interest expense
incurred on our $7.0 million loan and security agreement we secured in June 2006. This reduction is due to the principal payments we have been making on the 11.47% fixed rate loan since February 2007. As of March 31, 2008, we had made 14 of the
30 equal monthly principal and interest payments and had reduced the outstanding principal balance by $3.0 million, to $4.0 million. In January 2008, we began making the first of six interest-only payments on the $15.0 million facility and
thereafter will make 30 equal monthly principal and interest payments to fully amortize the balance.

As of March 31,
2008 and December 31, 2007 the aggregate principal balance of the loans, net of the loan discount, included on our condensed balance sheets was $18.4 million and $19.0 million, respectively.

Liquidity and Capital Resources

As
a biopharmaceutical company focused on in-licensing, developing and commercializing proprietary pharmaceutical product candidates, we have entered into license agreements to acquire the rights to develop and commercialize our two product candidates,
Acetavance and Omigard. Pursuant to these agreements, we obtained exclusive licenses to the patent rights and know-how for selected indications and territories. Under the Acetavance agreement, we paid to BMS a $25.0 million up-front fee
and may be required to make future milestone payments totaling up to $40.0 million upon the achievement of various milestones related to regulatory or commercial events. Under the Omigard agreement, we paid to Migenix an aggregate of
$2.0 million in the form of an up-front fee, including the purchase of 617,284 shares of Migenix common stock, and may be required to make future milestone payments totaling up to $27.0 million upon the achievement of various
milestones related to regulatory or commercial events. Under both agreements, we are also obligated to pay royalties on any net sales of the licensed products.

Our future capital uses and requirements depend on numerous forward-looking factors. These factors include, but are not limited to, the following:



| |  |  | the progress of our clinical trials, including expenses to support the trials and milestone payments that may become payable to BMS or Migenix;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the potential need to conduct additional clinical trials of our product candidates, or to increase the number of patients enrolled in our ongoing clinical trials;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to establish and maintain strategic collaborations, including licensing and other arrangements;

As of March 31, 2008, we had $91.4 million in cash and cash equivalents, an increase of $36.0 million from the $55.4 million at
December 31, 2007. This increase was primarily due to net proceeds received from our registered direct offering completed in February 2008 of approximately $49.1 million. Partially offsetting this increase during the first quarter of 2008 were
reductions to our cash and cash equivalents from cash used in operations ($12.1 million), principal payments on our debt obligations ($0.7 million) and the purchase of equipment ($0.3 million).

The $12.1 million of cash used in operations for the three months ended March 31, 2008 represents a $5.6 million increase from the
$6.5 million of cash used in operations during the comparable period in 2007. This increase was primarily due to an increase in the net loss we reported during the applicable period in 2008, primarily due to the increased research and development
activities related to the advancement of our clinical development programs and pre-commercialization manufacturing development activities. Also contributing to the increased cash outflow from operations were reductions in interest earned on our
investments from lower average yields, combined with increased interest expense from increased debt obligations during the three months ended March 31, 2008 as compared to the three months ended March 31, 2007.

During the three months ended March 31, 2008, our accounts payable and accrued liabilities balances increased $0.3 million as
compared to December 31, 2007. This increase was primarily due to increased activity and the timing of payments related to our clinical trials of Omigard and Acetavance.

As of March 31, 2008, our net property and equipment balance increased by $0.2 million to $5.3 million, from $5.1 million at December 31, 2007. This increase was primarily due to
capital expenditures of equipment for the commercial manufacturing of Omigard and computer software for our information technology infrastructure. These increases were partially offset by the depreciation of our assets during the three months ended
March 31, 2008.

Sources of Liquidity

Since inception, our operations have been financed primarily through the issuance of equity securities, in both public and private offerings. From our inception through March 31, 2008, we
have received net proceeds of approximately $184.7 million from the sale of shares of our preferred and common stock as follows:



| |  |  | from July 2004 to March 2008 (excluding our initial public offering and February 2008 registered direct offering), we issued and sold a total of
2,305,150 shares of common stock to our founders, employees, directors and consultants for aggregate net proceeds of $0.8 million;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | from July 2004 to August 2004, we issued and sold a total of 8,085,108 shares of Series A-1 preferred stock for aggregate net proceeds of
$7.5 million;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | from June 2005 to September 2005, we issued and sold a total of 17,675,347 shares of Series A-2 preferred stock for aggregate net proceeds of
$17.6 million;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in March 2006, we issued and sold a total of 53,870,000 shares of Series A-3 preferred stock for aggregate net proceeds of $53.8 million;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------

| |  |  | in the fourth quarter of 2006, we completed our initial public offering in which we issued and sold a total of 6,900,000 shares of our common stock for
aggregate net proceeds of $55.9 million; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in February 2008, we completed a registered direct offering pursuant to an effective shelf registration in which we issued and sold a total of 9,240,307 shares
of our common stock for aggregate net proceeds of $49.1 million.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Additionally, in February 2006, we
entered into a $7.0 million loan and security agreement with Silicon Valley Bank and Oxford Finance Corporation to provide us with growth capital. We drew down $7.0 million in June 2006 at the fixed rate of 11.47%. In November 2007, we
amended the $7.0 million loan and security agreement and entered into the Second Amendment to Loan and Security Agreement with the same parties and GE Business Financial Services Inc. (formerly known as Merrill Lynch Business Financial Services ,
Inc.), to secure an additional $15.0 credit facility. In December 2007, we drew down $15.0 million under the Second Amendment in two separate draws of $5.0 million and $10.0 million with fixed interest rates of 7.83% and 7.74%, respectively, net of
a loan fee of less than $0.1 million. In addition to the principal and interest under the $15.0 million credit facility, we are required to pay $0.4 million at the termination of the $15.0 million credit facility. As of March 31, 2008, we had
no further credit available under these agreements.

In August 2006, we began making the first of six interest-only
payments on the $7.0 million loan and security agreement and in February 2007, began making the first of 30 equal principal and interest payments. In January 2008, we began making the first of six interest-only payments on the $15.0 million credit
facility and thereafter will make 30 equal monthly principal and interest payments to fully amortize the balance. At the termination of the $15.0 million credit facility, we will also pay the $0.4 million termination fee.

In connection with each credit facility we issued warrants to the lenders to purchase share of our stock. See Note 7 to the Notes to
Condensed Financial Statements in Item 1 above for further discussion.

Capital Resources

Our current cash and cash equivalent balances are currently our principal sources of liquidity, which we believe will satisfy our
requirements for projected working capital, capital expenditures and debt servicing, at a minimum, through the next twelve months. We have based this estimate on assumptions that may prove to be wrong, and we could spend our available financial
resources faster than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to the rate of progress and cost of our clinical trials and other product development programs for Acetavance,
Omigard and any other product candidates that we may in-license or acquire. Until we can generate significant cash from our operations, we expect to continue to fund our operations with existing cash resources generated from the proceeds of
offerings of our equity securities and our existing borrowings under our amended loan and security agreement. In addition, we may finance future cash needs through the sale of additional equity securities, strategic collaboration agreements and debt
financing. However, we have drawn down all available amounts under our existing amended loan and security agreement, and we may not be successful in obtaining strategic collaboration agreements or in receiving milestone or royalty payments under
those strategic collaboration agreements. To the extent that we raise additional capital by issuing equity securities, our existing stockholders ownership will be diluted. We have invested a substantial portion of our available cash funds in
money market funds placed with reputable financial institutions for which credit loss is not anticipated and have established guidelines relating to diversification and maturities of our securities available-for-sale to preserve principal and
maintain liquidity. Also, we cannot be sure that our existing cash and investment resources will be adequate, that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or our
stockholders. Having insufficient funds may require us to delay, scale-back or eliminate some or all of our development programs, relinquish some or even all rights to product candidates at an earlier stage of development or renegotiate less
favorable terms than we would otherwise choose. Failure to obtain adequate financing also may adversely affect our ability to operate as a going concern. If we raise additional funds by issuing equity securities, substantial dilution to existing
stockholders would likely result. If we raise additional funds by incurring additional debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our
ability to operate our business.

Recent Accounting Pronouncements

See Note 3 to the Notes to Condensed Financial Statements in Item 1 above for a discussion of recent accounting pronouncements.

Caution on Forward-Looking Statements

This Quarterly Report on Form 10-Q, or
Quarterly Report, includes forward-looking statements that are subject to risks and uncertainties, many of which are beyond our control. Our actual results will differ from those anticipated in these forward looking statements as a result of various
factors, including those set forth below under the caption Part II., Item 1A.  Risk Factors and the differences may be material. Forward-looking statements discuss matters that are not historical facts.
Forward-looking statements include, but are not limited to, discussions regarding our operating strategy, growth strategy, acquisition strategy, cost savings initiatives, industry, economic conditions, financial condition, liquidity and capital
resources and results of operations. In this Quarterly Report, for example, we make forward-looking statements regarding the potential for Acetavance and Omigard to receive regulatory approval for one or more indications on a timely basis, or
at all; the progress and results of pending clinical trials for Acetavance and Omigard, including any delays in commencing or completing enrollment in our ongoing clinical trials; unexpected adverse side effects or inadequate therapeutic
efficacy of Acetavance or Omigard that could delay or prevent regulatory approval or commercialization, or that could result in recalls or product liability claims; other difficulties or delays in development, testing, manufacturing and
marketing of and obtaining regulatory approval for Acetavance or Omigard; the scope and validity of patent protection for Acetavance or Omigard; the market potential for pain, fever, local catheter site infections and other target markets,
and our ability to compete; the potential to attract a strategic collaborator and terms of any related transaction; intense competition if either of Acetavance or Omigard is ever commercialized; and our ability to raise sufficient capital when
needed, or at all. Such statements include, but are not limited to, statements preceded by, followed by or that otherwise include the words believes, expects, anticipates, intends,
estimates, projects, can, could, may, will, would or similar expressions. For those statements, we claim the protection of the safe harbor for forward-looking
statements contained in Section 21E of the Private Securities Litigation Reform Act of 1995. You should not rely unduly on these forward-looking statements, which speak only as of the date on which they were made. We undertake no obligation to
update publicly or revise any forward-looking statements, whether as a result of new information, future events or otherwise, unless required by law.

Item 3.Qualitative and Quantitative Disclosures about Market Risk

Cash
and Cash Equivalents

Our cash and cash equivalents as of March 31, 2008 consisted primarily of cash and money
market funds. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. The primary objective of our investment activities is to preserve principal while at the
same time maximizing the income we receive without significantly increasing risk. Some of the investment securities available-for-sale that we may invest in could be subject to market risk. This means that a change in prevailing interest rates may
cause the value of the investment securities available-for-sale to fluctuate. For example, if we purchase a security that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of that security will probably
decline. To minimize this risk, we intend to maintain a portfolio of cash equivalents and investment securities available-for-sale in a variety of securities which may include money market funds, government and non-government debt securities and
commercial paper, all with various maturity dates. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate and we do not believe that our results of
operations would be materially impacted by an immediate 10% change in interest rates.

Debt

The loans under our loan and security agreement have fixed interest rates. Consequently, we do not have significant interest rate cash
flow exposure on our debt. The aggregate principal balance of the loans under the agreement at March 31, 2008 was $19.0 million, and is collateralized by substantially all the assets of the Company (excluding intellectual property). Under the
terms of the agreement, we are precluded from entering into certain

financing and other transactions, including disposing of certain assets and paying dividends, and are subject to various non-financial covenants and
prepayment penalties.

Item 4.Controls and Procedures

We maintain
disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, is recorded, processed,
summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief
financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed
and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Evaluation of disclosure controls and procedures.As required by Securities and Exchange Commission Rule 13a-15(b), we
carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and
procedures as of the end of the period covered by this Quarterly Report. Based on the foregoing, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance
level.

Changes in internal control over financial reporting. There was no change in our internal control over
financial reporting that occurred during the period covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Not applicable.

Item 1A.Risk Factors

Certain factors
may have a material adverse effect on our business, financial condition and results of operations, and you should carefully consider them. Accordingly, in evaluating our business, we encourage you to consider the following discussion of risk
factors, which has been updated since the filing of our Annual Report on Form 10-K, in its entirety, in addition to other information contained in this report as well as our other public filings with the Securities and Exchange Commission.

In the near-term, the success of our business will depend on many factors, including the following risks:



| |  |  | we are largely dependent on the success of our only two product candidates, Acetavance and Omigard, and we cannot be certain that our ongoing and planned
clinical development programs will be successful, or sufficient to support new drug applications, or NDAs, or that either product candidate will receive regulatory approval or be successfully commercialized;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in the commencement, enrollment or completion of clinical testing for either of our product candidates, or significant issues regarding the adequacy of
our clinical trial designs or the execution or success of our clinical trials, could result in increased costs to us and delay or limit our ability to obtain regulatory approval;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the outcomes of final analyses of data from our clinical trials of Acetavance or Omigard may vary from our initial analyses, and the U.S. Food and Drug
Administration, or FDA, may not agree with our interpretation of these results;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our clinical trials of Acetavance or Omigard may produce negative or inconclusive results, or may be inconsistent with previous clinical trial results, and we
may decide, or the FDA may require us, to conduct additional clinical trials or to modify our ongoing clinical trials;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | even if our product candidates are approved by regulatory authorities, the market potential for pain, fever, local catheter site infections and other target
markets may be less than anticipated, and we expect intense competition in the hospital marketplace for our targeted indications;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unexpected adverse side effects or inadequate therapeutic efficacy of Acetavance or Omigard could delay or prevent regulatory approval or commercialization of
our product candidates, or result in recalls or product liability claims against us;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays or quality issues with respect to the completion of required pre-commercialization manufacturing development activities for our product candidates,
including the completion of adequate stability data, could result in increased costs to us, cause us to be required to perform additional non-clinical or clinical studies, and delay or limit our clinical trials and our ability to obtain regulatory
approval;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the patent rights that we have in-licensed covering Acetavance are limited to a specific intravenous formulation of acetaminophen, and our market opportunity
for this product candidate may be limited by the lack of patent protection for the active ingredient itself and other formulations that may be developed by competitors;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we will require substantial additional funding and may be unable to raise capital when needed, which would force us to delay, reduce or eliminate our
development programs and commercialization efforts; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may not be able to maintain patent protection for our products and to commercialize our products without infringing the patent rights of others.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Each of these factors, as well as other factors that may impact our business, are
described in more detail in the following discussion. Although the factors highlighted above are among the most significant, any of the following factors could materially adversely affect our business or cause our actual results to differ materially
from those contained in forward-looking statements we have made in this report and those we may make from time to time, and you should consider all of the factors described when evaluating our business.

Risks Related to Our Business and Industry

We
are largely dependent on the success of our two product candidates, Acetavance and Omigard, and we cannot be certain that either of these product candidates will receive regulatory approval or be successfully commercialized.

We currently have no drug products for sale and we cannot guarantee that we will ever have marketable drug products. The research,
testing, manufacturing, labeling, approval, selling, marketing and distribution of drug products are subject to extensive regulation by the FDA, and other regulatory authorities in the U.S. and other countries, which regulations differ from country
to country. We are not permitted to market our product candidates in the U.S. until we receive approval of a New Drug Application, or NDA, from the FDA. We have not submitted an NDA or received marketing approval for either of our product
candidates. Obtaining approval of an NDA is a lengthy, expensive and uncertain process. We currently have only two product candidates and our business success currently depends entirely on their successful development and commercialization.

We have not developed either of our product candidates independently. In March 2006, we in-licensed rights to
intravenous acetaminophen from Bristol-Myers Squibb Company, or BMS, which currently markets this product in Europe for the treatment of acute pain and fever. Our current clinical development program for this product candidate includes three Phase
III efficacy trials, two pharmacokinetic studies, two multi-day safety studies and a placebo-controlled, 48-hour safety trial, as well as other supportive studies conducted by Cadence, BMS or reported in scientific and medical literature. In
January 2008, we announced that our Phase III efficacy trial of Acetavance for the treatment of pain in adults following abdominal gynecological surgery did not meet its primary endpoint of demonstrating a statistically significant reduction in
patients pain intensity scores over 48 hours compared to placebo. We believe that the study missed its primary endpoint due to much higher than predicted variability of the initial pain assessments, particularly in those subjects who were
randomized closer to the end of their surgery. This variability had a large, negative impact on the baseline-dependent statistical measurements. As a result, we are now engaged in communications with the FDA to obtain the agencys advice
regarding our development program for this product candidate. Following these communications with the FDA, we may decide, or the FDA may require us, to conduct additional clinical trials of Acetavance, or to modify our ongoing clinical trials of
this product candidate, which would increase our costs and may delay or limit our ability to obtain regulatory approval. Depending upon the results of these communications with the FDA and assuming successful completion of all of our planned
clinical trials for this product candidate, we currently plan to submit a 505(b)(2) NDA to the FDA in the first half of 2009 requesting marketing approval of Acetavance for the treatment of acute pain and fever in adults and children. Additional
clinical trials may be required to support the approval of these indications and any additional indications or dosages for Acetavance, which could delay, or limit the scope of, any regulatory approvals for this product candidate. Our failure to
achieve our product development goals for Acetavance in a timely manner or at all could adversely affect our business and our stock price.

In July 2004, we in-licensed the rights to our only other product candidate, omiganan pentahydrochloride 1% aqueous gel, or Omigard. In 2005, we initiated a single Phase III clinical trial of Omigard for the
prevention of local catheter site infections, or LCSIs. In July 2007, we increased the number of patients to be enrolled in this trial from 1,250 to 1,850 patients, which required us to expend greater financial resources than originally
anticipated and delayed the completion of enrollment to April 2008. This trial must be successfully completed before we can submit an NDA to the FDA for the approval of Omigard.

These clinical development programs for Acetavance and Omigard may not lead to commercial products if our clinical trials fail to
demonstrate that our product candidates are safe and effective and, as a result, we fail to obtain necessary approvals from the FDA and similar foreign regulatory agencies. We may also fail to obtain the necessary approvals if we have inadequate
financial or other resources to advance our product candidates through the clinical trial process. Any failure to obtain approval of Acetavance or Omigard would have a material and adverse effect on our business.

##### Table of Contents

If clinical trials of our current or future product candidates do not produce results necessary to
support regulatory approval in the U.S. or elsewhere, we will be unable to commercialize these products.

To
receive regulatory approval for the commercial sale of Acetavance, Omigard or any other product candidates that we may in-license or acquire, we must conduct, at our own expense, adequate and well-controlled clinical trials to demonstrate efficacy
and safety in humans. Clinical testing is expensive, takes many years and has an uncertain outcome. Clinical failure can occur at any stage of the testing. Our clinical trials may produce negative or inconclusive results, and we may decide, or
regulators may require us, to conduct additional clinical and/or non-clinical testing.

For example, Migenix, the licensor
for our Omigard product candidate, together with its former collaborator, Fujisawa Healthcare, Inc., or Fujisawa, completed enrollment in a Phase III clinical trial in February 2003 that demonstrated statistically significant results for the
secondary endpoints of the trial, the prevention of LCSIs and catheter colonization, which is the growth of microorganisms on the portion of the catheter below the skin surface. However, the trial did not show statistical significance for the
primary endpoint, the prevention of catheter-related bloodstream infections, or CRBSIs. After the termination of the collaboration between Migenix and Fujisawa in January 2004, we in-licensed the rights to Omigard from Migenix in
July 2004, and subsequently reached an agreement under the SPA process with the FDA concerning the protocol for our own Phase III clinical trial of Omigard. In connection with the SPA for Omigard, the FDA agreed that a single confirmatory Phase
III clinical trial will be required for approval for Omigard and that the prevention of LCSIs will be the sole primary efficacy endpoint, and we initiated this clinical trial, which is called the CLIRS trial, in August 2005. In July 2007,
we increased the number of patients to be enrolled in the CLIRS trial from 1,250 to 1,850 patients in order to increase the statistical power of the study. This change was prompted by our planned re-analysis of data from the initial Phase III
clinical trial of Omigard, which indicated a statistically significant reduction in the number of LCSIs of 42% in the Omigard treatment arm as compared to the povidone-iodine treatment arm, while the original analysis of data from this trial
indicated a statistically significant reduction of LCSIs of approximately 49%. Increasing the number of patients enrolled in this clinical trial has required greater financial resources than originally anticipated and delayed the completion of
enrollment from the second half of 2007 to April 2008. We cannot be certain that our Phase III clinical trial of Omigard will demonstrate statistical significance or otherwise demonstrate sufficient efficacy and safety to support the filing of an
NDA or ultimately lead to regulatory approval. Furthermore, despite having completed the SPA process, the FDAs agreement with us on the trial protocol remains subject to future advances in the field or future public health concerns
unrecognized at the time of the FDAs protocol assessment, and any further changes we may propose to the protocol will remain subject to the FDAs approval.

Our clinical development programs are subject to the risk of failure inherent in the development of new drugs, and our clinical trials may not demonstrate the safety, tolerability and
effectiveness of our product candidates. For example, in January 2008, we announced that our Phase III efficacy trial of Acetavance for the treatment of pain in adults following abdominal gynecological surgery did not meet its primary endpoint
of demonstrating a statistically significant reduction in patients pain intensity scores over 48 hours compared to placebo. Delays in completing our clinical trials or the rejection of data from a clinical trial by regulatory authorities will
result in increased development costs and could have a material adverse effect on the development of our product candidates. In addition, our failure to adequately demonstrate the efficacy and safety of Acetavance, Omigard or any other product
candidates that we may in-license or acquire would prevent receipt of regulatory approval and, ultimately, the commercialization of that product candidate.

Because the results of earlier clinical trials are not necessarily predictive of future results, Acetavance, Omigard or any other product candidate we advance into clinical trials may not have favorable results
in later clinical trials or receive regulatory approval.

Success in clinical testing and early clinical trials
does not ensure that later clinical trials will generate adequate data to demonstrate the efficacy and safety of the investigational drug. A number of companies in the pharmaceutical industry, including those with greater resources and experience
than us, have suffered significant setbacks in Phase III clinical trials, even after promising results in earlier clinical trials.

##### Table of Contents

In March 2006, we in-licensed the rights to Acetavance from BMS, which is currently
marketing intravenous acetaminophen in Europe and other parts of the world under the brand name Perfalgan. Nine post-operative pain clinical trials have been completed, mostly in Europe, primarily in support of European regulatory approvals for this
product candidate. However, we do not know at this time what regulatory weight, if any, the U.S. and Canadian regulatory agencies will give to these clinical data in supplementing clinical data generated by us for potential regulatory approval of
Acetavance in the U.S. and Canada. The FDA and foreign regulatory agencies may reject these clinical trial results if they determine that the clinical trials were not conducted in accordance with requisite regulatory standards and procedures.
Furthermore, we have not audited or verified the accuracy of the primary clinical data provided by BMS and cannot determine their applicability to our regulatory filings. Even though BMS has obtained marketing approval in Europe and other
territories for intravenous acetaminophen, we must conduct additional adequate and well controlled clinical trials in the U.S. to demonstrate Acetavances safety and efficacy in specific indications to gain regulatory approval in the U.S.

In January 2008, we announced top-line results for our Phase III efficacy trial of Acetavance for the treatment of
pain in adults following abdominal gynecological surgery. This trial did not meet its primary endpoint of demonstrating a statistically significant reduction in patients pain intensity scores over 48 hours compared to placebo. However, this
same trial demonstrated a favorable safety profile for Acetavance over a 48-hour period, and met several secondary endpoints, including pain relief, global patient satisfaction and time to rescue medication. We also announced the results of a Phase
III clinical trial of Acetavance for the treatment of fever in adults, which successfully met its primary endpoint, demonstrating a statistically significant reduction of endotoxin-induced fever over six hours compared to placebo, and key secondary
endpoints. As a result of the outcome of these clinical trials, we are now engaged in communications with the FDA to obtain the agencys advice regarding our development program for this product candidate. Following our communications with the
FDA, we may also decide or the FDA may require us to conduct additional clinical trials to support the approval of these indications and any additional indications or dosages for Acetavance, which could delay, or limit the scope of, any regulatory
approvals for this product candidate. In May 2008, we announced that our second Phase III clinical trial of Acetavance for the treatment of fever in adults successfully met the primary endpoint, which is the weighted sum of temperature differences
over two hours, demonstrating a statistically significant more rapid onset of action in reducing experimentally-induced fever compared to the same dose of orally-administered acetaminophen. The mean temperature scores for the Acetavance-treated
group were significantly lower as early as 15 minutes after the study drug was administered, and the mean peak temperature observed in the Acetavance group was also significantly lower. We currently plan to announce the results of a Phase III
clinical trial of Acetavance for the treatment of acute pain in adults following abdominal laparoscopic surgery in the second half of 2008. If the results of our clinical trials are unfavorable or insufficient to demonstrate the safety and efficacy
of Acetavance, or do not demonstrate the same safety and efficacy for Acetavance as was demonstrated previously by BMS, we may be forced to further revise the development plan for this product candidate, which could involve additional significant
expense and delay.

Our other product candidate, Omigard, is not yet approved in any jurisdiction. No antimicrobial peptide
has been approved by the FDA, including two antimicrobial peptides with mechanisms of action similar to Omigard that were studied in Phase III clinical trials. Although Omigard has been studied in more than 750 patients, all of the patients studied
were enrolled in trials conducted or sponsored by Migenix or Fujisawa. Similar to Acetavance, we obtained electronic databases from the completed Phase III clinical trials sponsored by Migenix and Fujisawa. As a part of our standard procedure for
analyzing data to prepare a final report of the study for a potential NDA or other applications for marketing authorization, we re-analyzed the data using a slightly different, stricter definition of LCSIs. Our re-analysis indicated a statistically
significant reduction in the number of LCSIs of 42% in the Omigard treatment arm as compared to the povidone-iodine treatment arm, while the original analysis indicated a statistically significant reduction of LCSIs of approximately 49%. Because the
target sample size for our own Phase III clinical trial of Omigard, called the CLIRS trial, is based, in part, upon the LCSI rate and treatment effect of the original Phase III clinical trial of this product candidate, we determined that adding
patients would be prudent in order to maintain the statistical power of the study. In July 2007, we increased the number of patients to be enrolled in the CLIRS trial from 1,250 to 1,850 patients. Increasing the number of patients in this study
required greater financial resources than originally anticipated and delayed the completion of enrollment from the second half of 2007 to April 2008. Our audit and verification of the accuracy of the primary clinical data provided by our licensor
and its former collaborator are continuing, and we cannot determine their applicability to our regulatory filings. Although the Phase III clinical trial of Omigard conducted by Migenix and Fujisawa demonstrated favorable, statistically significant
results for the prevention of LCSIs and catheter colonization, secondary endpoints in their trial, we may not observe

##### Table of Contents

similar results in the CLIRS trial. Furthermore, the earlier Phase III clinical trial failed to show statistical significance for the primary endpoint of
that trial, the prevention of CRBSIs. While we will measure the prevention of CRBSIs as a secondary endpoint in our Phase III clinical trial of Omigard, our trial is not designed to demonstrate statistical significance for this secondary endpoint.
Although we are targeting a different primary endpoint in our trial, the prevention of LCSIs, it is possible that we will experience similar, unexpected results. Failure to satisfy a primary endpoint in a Phase III clinical trial would generally
mean that a product candidate would not receive regulatory approval without one or more further successful Phase III clinical trials.

The data collected from our clinical trials or clinical trials conducted by our licensors may not be adequate to support regulatory approval of Acetavance, Omigard or any other product candidates that we may
in-license or acquire. Moreover, all clinical data reported is taken from databases that may not have been fully reconciled against medical records kept at the clinical sites. As a result of auditing the data from these earlier clinical trials and
completing the extensive re-analyses that we will need to perform as part of our standard procedures for preparing final reports of these studies, the previously reported results may change, which may negatively impact our ongoing Phase III clinical
trials, or the suitability of earlier clinical trials for inclusion in applications for marketing authorization of our Acetavance and Omigard product candidates. As a result, despite the results reported by others in earlier clinical trials for our
product candidates, we do not know whether any Phase III or other clinical trials that we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market our product candidates. Our failure to successfully
complete our clinical trials and obtain regulatory approval for Acetavance and Omigard would adversely affect our business and our stock price.

Delays in the commencement or completion of clinical trials, or significant issues regarding the adequacy of our clinical trial designs or the success or execution of our clinical trials, could result in
increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.

If
we experience delays in the commencement or completion of our clinical trials, we could incur significantly higher product development costs and our ability to obtain regulatory approvals for our product candidates could be delayed. We may also fail
to obtain the necessary regulatory approvals if we have inadequate financial or other resources to advance our product candidates through the clinical trial process. Following the announcement of the results of our Phase III efficacy trial of
Acetavance for the treatment of pain in adults following abdominal gynecological surgery, we initiated communications with the FDA to obtain the agencys advice regarding our development program for this product candidate. If our clinical
trials are successful, we currently plan to submit a 505(b)(2) NDA to the FDA for Acetavance in the first half of 2009. We do not know whether enrollment in our planned and ongoing clinical trials of Acetavance will be completed on time, if at all,
and, depending upon the results of our communications with the FDA and the results of our other clinical trials for this product candidate, we may decide or the FDA may require us to conduct additional clinical trials of Acetavance, which would
increase our costs and may further delay this estimated submission date.

The commencement and completion of clinical
trials requires us to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other clinical trial programs for the same indication as our product candidates or may not be eligible to participate in or may
be required to withdraw from a clinical trial as a result of changing standards of care. For example, we believe that improvements to hospital infection prevention practices since we commenced enrollment in our Phase III clinical trial of Omigard
may reduce catheter-related infection rates, which may result in the occurrence of an insufficient number of infections to demonstrate a clinically meaningful treatment difference that achieves statistical significance in this clinical trial, even
with a larger number of enrolled patients. Although the FDA agreed with our proposal to increase the number of patients to be enrolled in our ongoing Phase III clinical trial of Omigard, we may still be unable to demonstrate sufficient efficacy and
safety to support the filing of an NDA for Omigard.

The commencement and completion of clinical trials can be delayed for
a variety of other reasons, including delays related to:



| |  |  | reaching agreements on acceptable terms with prospective clinical research organizations, or CROs, and trial sites, the terms of which can be subject to
extensive negotiation and may vary significantly among different CROs and trial sites;

| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, a clinical trial may be
suspended or terminated by us, the FDA or other regulatory authorities due to a number of factors, including:



| |  |  | failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | inspections of our own clinical trial operations, the operations of our CROs, or our clinical trial sites by the FDA or other regulatory authorities, which may
result in the imposition of a clinical hold or, potentially, prevent us from using some of the data generated from our clinical trials to support requests for regulatory approval of our product candidates;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | new information suggesting unacceptable risk to subjects, or unforeseen safety issues or any determination that a trial presents unacceptable health risks;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | new information suggesting that the target condition occurs too infrequently for the product candidate to demonstrate efficacy; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | lack of adequate funding to continue the clinical trial, including the incurrence of unforeseen costs due to enrollment delays, requirements to conduct
additional trials and studies and increased expenses associated with the services of our CROs and other third parties.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Additionally, changes in regulatory requirements and guidance may occur, or new information concerning the product candidate or the target medical condition may emerge, and we may need to perform additional,
unanticipated non-clinical testing of our product candidates or amend clinical trial protocols to reflect these developments. Additional non-clinical or clinical testing would add costs and could delay or result in the denial of regulatory approval
for our product candidates. Amendments may require us to resubmit our clinical trial protocols to institutional review boards for reexamination, which may impact the costs, timing or successful completion of a clinical trial. If we experience delays
in the completion of, or if we terminate, our clinical trials, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenues will be delayed. In addition, many of the factors that cause, or lead to,
a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Even if we are able to ultimately commercialize our product candidates, other therapies for the same
indications may have been introduced to the market and established a competitive advantage.

We expect intense competition in the
territories in which we have rights to our product candidates, and new products may emerge that provide different or better therapeutic alternatives for our targeted indications.

The biotechnology and pharmaceutical industries are subject to rapid and intense technological change. We face, and will continue to
face, competition in the development and marketing of our product candidates from academic institutions, government agencies, research institutions and biotechnology and pharmaceutical companies. There can be no assurance that developments by others
will not render our product candidates obsolete or noncompetitive. Furthermore, new developments, including the development of other drug technologies and methods of preventing the incidence of disease, occur in the pharmaceutical industry at a
rapid pace. These developments may render our product candidates obsolete or noncompetitive.

We intend to develop
Acetavance for the treatment of acute pain in the hospital setting, which will compete with well-established products for this and similar indications, including opioids such as morphine, fentanyl, meperidine



27

##### Table of Contents

and hydromorphone, each of which is available generically from several manufacturers, and several of which are available as proprietary products using novel
delivery systems, as well as an extended release injectable (epidural) formulation of morphine, DepoDur. Ketorolac, an injectable non-steroidal anti-inflammatory drug, or NSAID, is also available generically in the U.S. from several
manufacturers and used to treat acute pain. During the time that it will take us to obtain regulatory approval for Acetavance, if at all, we anticipate that several additional products may be developed for the treatment of acute pain, including
other injectable NSAIDs, novel opioids, new formulations of currently available opioids, long-acting local anesthetics and new chemical entities as well as alternative delivery forms of various opioids and NSAIDs.

We are also developing our Omigard product candidate for the prevention of catheter-related infections in the hospital setting. If
approved, Omigard will compete with well-established topical products that are currently used in practice to prevent these infections as well as BioPatch, a device marketed by Johnson & Johnson, which has been approved for wound dressing
and prevention of catheter-related infections. A chlorhexidine-containing, transparent dressing for the prevention of catheter-related infections has also been recently introduced into the U.S. market by 3M Corporation. Other competitive products
may also be under development.

In addition, competitors may seek to develop alternative formulations of our product
candidates that address our targeted indications that do not directly infringe on our in-licensed patent rights. For example, we are aware of several U.S. and Canadian patents and patent applications covering various potential injectable
formulations of acetaminophen, including intravenous formulations, as well as methods of making and using these potential formulations. Furthermore, there are third-party patents covering analogs of omiganan and Migenix has patented analogs of
omiganan that are not licensed to us. The commercial opportunity for our product candidates could be significantly harmed if competitors are able to develop alternative formulations outside the scope of our in-licensed patents. Compared to us, many
of our potential competitors have substantially greater:



| |  |  | capital resources;
| | - |  | ------------------



| |  |  | development resources, including personnel and technology;
| | - |  | ----------------------------------------------------------



| |  |  | clinical trial experience;
| | - |  | --------------------------



| |  |  | regulatory experience;
| | - |  | ----------------------



| |  |  | expertise in prosecution of intellectual property rights; and
| | - |  | -------------------------------------------------------------



| |  |  | manufacturing, distribution and sales and marketing experience.
| | - |  | ---------------------------------------------------------------

As a result of these factors, our competitors may obtain regulatory approval of their products more rapidly than we are able to or may obtain patent protection or other intellectual property
rights that limit our ability to develop or commercialize our product candidates. Our competitors may also develop drugs that are more effective, useful and less costly than ours and may also be more successful than us in manufacturing and marketing
their products. We also expect to face similar competition in our efforts to identify appropriate collaborators or partners to help develop or commercialize our product candidates in markets outside the U.S.

If any of our product candidates for which we receive regulatory approval do not achieve broad market acceptance, the revenues that we generate
from their sales will be limited.

The commercial success of our product candidates for which we obtain marketing
approval from the FDA or other regulatory authorities will depend upon the acceptance of these products by the medical community and coverage and reimbursement of them by third-party payors, including government payors. The degree of market
acceptance of any of our approved products will depend on a number of factors, including:



| |  |  | limitations or warnings contained in a products FDA-approved labeling, including potential limitations or warnings for Acetavance that may be more
restrictive than oral formulations of acetaminophen;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the standard of care for the targeted indications for either of our product candidates could reduce the marketing impact of any superiority claims
that we could make following FDA approval;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | limitations inherent in the approved indication for either of our product candidates compared to more commonly-understood or addressed conditions, including, in
the case for Omigard, the ability to promote Omigard to hospitals and physicians who may be more focused on an indication specifically for the prevention of CRBSIs compared to the prevention of LCSIs, the primary endpoint in our Phase III clinical
trial; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potential advantages over, and availability of, alternative treatments, including, in the case of Acetavance, a number of products already used to treat acute
pain in the hospital setting, and in the case for Omigard, a number of competitive topical products as well as a device that has been approved for wound dressing and prevention of catheter-related infections.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our ability to effectively promote and sell our product candidates in the hospital marketplace will also depend on pricing and cost
effectiveness, including our ability to produce a product at a competitive price and our ability to obtain sufficient third-party coverage or reimbursement. Since many hospitals are members of group purchasing organizations, which leverage the
purchasing power of a group of entities to obtain discounts based on the collective buying power of the group, our ability to attract customers in the hospital marketplace will also depend on our ability to effectively promote our product candidates
to group purchasing organizations. We will also need to demonstrate acceptable evidence of safety and efficacy as well as relative convenience and ease of administration. Market acceptance could be further limited depending on the prevalence and
severity of any expected or unexpected adverse side effects associated with our product candidates. If our product candidates are approved but do not achieve an adequate level of acceptance by physicians, health care payors and patients, we may not
generate sufficient revenue from these products, and we may not become or remain profitable. In addition, our efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources
and may never be successful.

The decreasing use of the comparator product in our clinical trial of Omigard and improvements in
hospital infection control practices that lower catheter infection rates may adversely impact our ability to demonstrate a statistically significant treatment difference for Omigard and hinder the competitive profile of this product candidate.

Over the last several years, many hospitals, particularly in the U.S., have increased the use of a particular
antiseptic, chlorhexidine, as their standard of care to sterilize catheter insertion sites. Delays in the completion of data analysis for our Phase III clinical trial of Omigard and any other studies we may conduct to compare Omigard to
chlorhexidine or another topical antiseptic could significantly affect our product development costs, our prospects for regulatory approval and our ability to compete. Furthermore, the decreasing use of 10% povidone-iodine in favor of chlorhexidine
could reduce the marketing impact of any superiority claims that we could make following FDA approval. For example, hospitals and physicians may be reluctant to adopt Omigard for use in combination with chlorhexidine antisepsis for the prevention of
LCSIs. Additionally, we believe that improvements in hospital infection control practices since we commenced enrollment in our Phase III clinical trial of Omigard may reduce catheter-related infection rates, which may result in the occurrence of an
insufficient number of infections to demonstrate a statistically significant treatment difference in this clinical trial. Even if Omigard is approved by the FDA, if this product candidate does not achieve an adequate level of acceptance by
physicians, health care payors and patients, we may be unable to generate sufficient revenues to recover our development costs or otherwise sustain and grow our business.

Even if our product candidates receive regulatory approval, they may still face future development and regulatory difficulties.

Even if U.S. regulatory approval is obtained, the FDA may still impose significant restrictions on a products indicated uses or marketing or impose ongoing requirements for potentially
costly post-approval studies. Any of these restrictions or requirements could adversely affect our potential product revenues. For example, the label ultimately approved for Acetavance, Omigard or any other product candidates that we may in-license
or acquire, if any, may include a restriction on the term of its use, or it may not include one or more of our intended indications.

Our product candidates will also be subject to ongoing FDA requirements for the labeling, packaging, storage, advertising, promotion, record-keeping and submission of safety and other post-market information on the
drug. In

addition, approved products, manufacturers and manufacturers facilities are subject to continual review and periodic inspections. If a regulatory
agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose restrictions on that product
or us, including requiring withdrawal of the product from the market. If our product candidates fail to comply with applicable regulatory requirements, such as current Good Manufacturing Practices, or cGMPs, a regulatory agency may:



| |  |  | issue warning letters or untitled letters;
| | - |  | ------------------------------------------



| |  |  | require us to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due dates for specific
actions and penalties for noncompliance;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | impose other civil or criminal penalties;
| | - |  | -----------------------------------------



| |  |  | suspend regulatory approval;
| | - |  | ----------------------------



| |  |  | suspend any ongoing clinical trials;
| | - |  | ------------------------------------



| |  |  | refuse to approve pending applications or supplements to approved applications filed by us;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | impose restrictions on operations, including costly new manufacturing requirements; or
| | - |  | --------------------------------------------------------------------------------------



| |  |  | seize or detain products or require a product recall.
| | - |  | -----------------------------------------------------

Even if our product candidates receive regulatory approval in the U.S., we may never receive approval or commercialize our products outside of the U.S.

Our rights to Acetavance are limited to the U.S. and Canada, and our rights to Omigard are limited to North America and Europe. In order
to market any products outside of the U.S., we must comply with numerous and varying regulatory requirements of other countries regarding non-clinical testing, manufacturing, safety and efficacy. Approval procedures vary among countries and can
involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from that required to obtain FDA approval. The regulatory approval process in other countries may
include all of the risks detailed above regarding FDA approval in the U.S. as well as other risks. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one
country may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA
approval in the U.S. As described above, such effects include the risks that our product candidates may not be approved for all indications requested, which could limit the uses of our product candidates and have an adverse effect on product sales
and potential royalties, and that such approval may be subject to limitations on the indicated uses for which the product may be marketed or require costly, post-marketing follow-up studies.

We have never marketed a drug before, and if we are unable to establish an effective sales and marketing infrastructure, we will not be able to
successfully commercialize our product candidates.

In the U.S., we plan to build our own sales force to market our
products directly to physicians, nurses, hospitals, group purchasing organizations and third-party payors. We currently do not have significant internal sales, distribution and marketing capabilities. In order to commercialize any of our product
candidates, we must either acquire or internally develop sales and marketing capabilities, or enter into collaborations with partners to perform these services for us. The acquisition or development of a hospital-focused sales and marketing
infrastructure for our domestic operations will require substantial resources, will be expensive and time consuming and could negatively impact our commercialization efforts, including delay any product launch. Moreover, we may not be able to hire a
sales force that is sufficient in size or has adequate expertise. If we are unable to establish our sales and marketing capability or any other capabilities necessary to commercialize any products we may develop, we will need to contract with third
parties to market and sell our products. If we are unable to establish adequate sales and marketing capabilities, whether independently or with third parties, we may not be able to generate any product revenue, may generate increased expenses and
may never become profitable.

We will need to obtain FDA approval of our proposed product names, Acetavance and Omigard, and any
failure or delay associated with such approval may adversely impact our business.

Any name we intend to use for
our product candidates will require approval from the FDA regardless of whether we have secured a formal trademark registration from the U.S. Patent and Trademark Office. The FDA typically conducts a rigorous review of proposed product names,
including an evaluation of the potential for confusion with other product names. The FDA may also object to a product name if it believes the name inappropriately implies medical claims. If the FDA objects to either of the product names Acetavance
or Omigard, we may be required to adopt an alternative name for those product candidates. If we adopt an alternative name, we would lose the benefit of our existing trademark applications for Acetavance and/or Omigard and may be required to expend
significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a
successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product candidates.

Our product candidates may have undesirable side effects that could delay or prevent their regulatory approval or commercialization.

If concerns are raised regarding the safety of a new drug as a result of undesirable side effects identified during clinical testing, the FDA may decline to approve the drug at the end of the
normal NDA review period and issue a letter requesting additional data or information prior to making a final decision regarding whether or not to approve the drug. The number of such letters, which are referred to as approvable letters, issued by
FDA in recent years has increased, and resulted in substantial delays in the approval of several new drugs. Undesirable side effects caused by our product candidates could interrupt, delay or halt clinical trials, and could result in the issuance of
an approvable letter in response to our NDA applications, denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications, and in turn prevent us from commercializing our product candidates and generating
revenues from their sale. For example, the adverse events related to Acetavance observed in clinical trials completed to date include transient liver enzyme elevations, nausea or vomiting, allergic reactions, and pain or local skin reactions at the
injection site. When used in excess of the current guidelines for administration, acetaminophen has an increased potential to cause liver toxicity. While we do not expect the administration of acetaminophen in intravenous form will result in an
increased risk of toxicity to the liver compared with an equivalent dose of acetaminophen administered orally, we cannot be certain that increased liver toxicity or other drug-related side effects will not be observed in future clinical trials , or
as a result of sales of the same formulation of intravenous acetaminophen by BMS in Europe and other countries, or that the FDA will not require additional trials or impose more severe labeling restrictions due to liver toxicity or other concerns.
Drug-related adverse events observed in clinical trials completed to date for Omigard have been primarily limited to local skin reactions, including redness, swelling, bleeding, itching, bruising and pain. Although these drug-related adverse events
have generally been related to the skin, including the catheter insertion site, we cannot be certain that other drug-related side effects will not be reported in clinical trials that we may conduct or thereafter. Additionally, the same active
compound contained in Omigard is currently being developed for the treatment of dermatological diseases and disorders by Cutanea Life Sciences, Inc., or Cutanea, another licensee of Migenix. If Cutanea identifies new side effects or other adverse
events related to the compound during their pre-clinical or clinical development activities, regulatory authorities may require us to perform additional non-clinical or clinical testing in order to address such concerns. Such additional testing
would add costs and could delay or result in the denial of regulatory approval for Omigard.

If either of our product
candidates receives marketing approval and we or others later identify undesirable side effects caused by the product:



| |  |  | regulatory authorities may require the addition of labeling statements, specific warnings or a contraindication;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | regulatory authorities may suspend or withdraw their approval of the product, or require it to be removed from the market;
| | - |  | --------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our reputation may suffer.
| | - |  | --------------------------

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase our commercialization costs and expenses, which in turn could delay or
prevent us from generating significant revenues from its sale.

If the government or third-party payors fail to provide coverage and
adequate coverage and payment rates for our future products, if any, or if hospitals choose to use therapies that are less expensive, our revenue and prospects for profitability will be limited.

In both domestic and foreign markets, our sales of any future products will depend in part upon the availability of coverage and
reimbursement from third-party payors. Such third-party payors include government health programs such as Medicare, managed care providers, private health insurers and other organizations. In particular, many U.S. hospitals receive a fixed
reimbursement amount per procedure for certain surgeries and other treatment therapies they perform. Because this amount may not be based on the actual expenses the hospital incurs, hospitals may choose to use therapies which are less expensive when
compared to our product candidates. Accordingly, Acetavance, Omigard or any other product candidates that we may in-license or acquire, if approved, will face competition from other therapies and drugs for these limited hospital financial resources.
We may need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to the satisfaction of hospitals, other target customers and their third-party payors. Such studies might require us to commit a
significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Adequate third-party coverage and reimbursement might not be available to enable us to maintain price
levels sufficient to realize an appropriate return on investment in product development.

Governments continue to propose
and pass legislation designed to reduce the cost of healthcare. In the U.S., we expect that there will continue to be federal and state proposals to implement similar governmental controls. For example, in December 2003, Congress enacted a
limited prescription drug benefit for Medicare beneficiaries in the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. Under this program, drug prices for certain prescription drugs are negotiated by drug plans, with the goal to
lower costs for Medicare beneficiaries. In some foreign markets, the government controls the pricing of prescription pharmaceuticals. In these countries, pricing negotiated with governmental authorities can take six to 12 months or longer after
the receipt of regulatory marketing approval for a product. Cost control initiatives could decrease the price that we would receive for any products in the future, which would limit our revenue and profitability. Accordingly, legislation and
regulations affecting the pricing of pharmaceuticals might change before our product candidates are approved for marketing. Adoption of such legislation could further limit reimbursement for pharmaceuticals.

If we breach any of the agreements under which we license rights to our product candidates from others, we could lose the ability to continue the
development and commercialization of our product candidates.

In March 2006, we entered into an exclusive
license agreement with BMS relating to our Acetavance product candidate for the U.S. and Canada, and in July 2004, we entered into an exclusive license agreement with Migenix relating to our Omigard product candidate for North America and
Europe. Because we have in-licensed the rights to our two product candidates from third parties, if there is any dispute between us and our licensors regarding our rights under these license agreements, our ability to develop and commercialize these
product candidates may be adversely affected. Any uncured, material breach under these license agreements could result in our loss of exclusive rights to the related product candidate and may lead to a complete termination of our product development
efforts for the related product candidate.

If BMS breaches the underlying agreement under which we sublicense the rights to our
Acetavance product candidate, we could lose the ability to develop and commercialize Acetavance.

Our license for
Acetavance is subject to the terms and conditions of a license from SCR Pharmatop to BMS, under which BMS originally licensed the intellectual property rights covering Acetavance. If BMS materially breaches the terms or conditions of this underlying
license from SCR Pharmatop, and neither BMS nor we adequately cure that breach, or BMS and SCR Pharmatop otherwise become involved in a dispute, the breach by



32

##### Table of Contents

BMS or disputes with SCR Pharmatop could result in a loss of, or other material adverse impact on, our rights under our license agreement with BMS. While we
would expect to exercise all rights and remedies available to us, including seeking to cure any breach by BMS, and otherwise seek to preserve our rights under the patents licensed by SCR Pharmatop, we may not be able to do so in a timely manner, at
an acceptable cost or at all. Any uncured, material breach under the license from SCR Pharmatop to BMS could result indirectly in our loss of exclusive rights to our Acetavance product candidate and may lead to a complete termination of our product
development and any commercialization efforts for Acetavance.

We rely on third parties to conduct our clinical trials, including our
ongoing Phase III clinical program for Acetavance and our Phase III clinical trial of Omigard. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval
for or commercialize our product candidates on our anticipated timeline or at all.

We rely primarily on
third-party CROs to manage the execution of our clinical trials for our Acetavance and Omigard product candidates, and we depend on independent clinical investigators, medical institutions and contract laboratories to conduct our clinical trials.
Although we rely on CROs to manage the execution of our clinical trials, we are responsible for oversight and for ensuring that each of our clinical trials is conducted in accordance with its investigational plan and protocol. Moreover, the FDA
requires us and our CROs to comply with regulations and standards, commonly referred to as good clinical practices, or GCPs, for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are
scientifically credible and accurate and that the trial subjects are adequately informed of the potential risks of participating in clinical trials. Our reliance on CROs does not relieve us of these responsibilities and requirements. CROs and
investigators are not our employees, and we cannot control the amount or timing of resources that they devote to our programs. If our CROs or independent investigators fail to devote sufficient care, time and resources to our drug development
programs, if their performance is substandard, or if they are inspected by the FDA and are found not to be in compliance with GCPs, it will delay the approval of our FDA applications and our introductions of new products. The CROs with which we
contract for execution of our clinical trials play a significant role in the conduct of the trials and the subsequent collection and analysis of data. Failure of the CROs to meet their obligations could adversely affect clinical development of our
product candidates. Moreover, these independent investigators and CROs may also have relationships with other commercial entities, some of which may have competitive products under development or currently marketed. If independent investigators and
CROs assist our competitors, it could harm our competitive position. If any of these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, or if the quality or accuracy of the clinical data
is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for Acetavance, Omigard or future product candidates.

If the manufacturers upon whom we rely fail to complete required pre-commercialization manufacturing development activities on time, we may face
delays in the development of, or in obtaining regulatory approvals for, our product candidates, which would result in increased costs and the loss of potential revenues.

We do not manufacture any of our product candidates, and we do not currently plan to develop any capacity to do so. Instead, we rely on
third party manufacturers to perform pre-commercialization manufacturing development activities for, and manufacture, Acetavance, Omigard and, most likely, any other product candidates that we may in-license or acquire in the future. As a result, we
are subject to production scheduling constraints, systems and equipment failures, labor and materials shortages, and other business and financial issues experienced by our third party manufacturers. Any problems or delays we experience in preparing
for commercial-scale manufacturing of a product candidate may cause us to experience increased costs, result in delays in receiving FDA or other regulatory approvals, or impair our ability to manufacture our product candidates, which would adversely
affect our business. For example, as a part of our applications for regulatory approval, our manufacturers will need to produce specific batches of our product candidates to demonstrate acceptable stability under various conditions and for
commercially viable lengths of time. The production of these batches by our third party manufacturers may require specialized equipment and materials, and may involve the development of new processes and methods that may take a substantial amount of
time to implement. We and our contract manufacturers will need to demonstrate to the FDA and other regulatory authorities this acceptable stability data, as well as validate methods and manufacturing processes, in order to receive regulatory
approval to commercialize our product candidates. Any delays in the availability of this data may cause delays in the submission of applications for regulatory approval of our product candidates, and consequent delays in receiving FDA or other
regulatory authority approvals. Additionally, the FDA

is likely to conduct inspections of our manufacturers facilities from time to time, including as part of its review of any marketing applications we
may file. If our manufacturers are not in compliance with cGMP requirements, this may delay the approval by the FDA of these marketing applications, or result in delays in the availability of our product candidates to complete clinical trials or for
commercial distribution.

If the manufacturers upon whom we rely terminate our supply agreements or fail to produce our product
candidates in the volumes we require on a timely basis, or to comply with stringent regulations applicable to pharmaceutical manufacturers, we may face delays in the development and commercialization of, or be unable to meet demand for, our product
candidates and may lose potential revenues.

If the commercial manufacturers upon whom we rely to manufacture our
product candidates fail to deliver the required commercial quantities of bulk drug substance or finished product on a timely basis at commercially reasonable prices that meet all applicable quality standards, we would likely be unable to meet demand
for our products and we would lose potential revenues. We have entered into a development and supply agreement with Baxter Healthcare Corporation, or Baxter, for the completion of pre-commercialization manufacturing development activities and the
manufacture of commercial supplies of the finished Acetavance. Any termination or disruption of our relationship with Baxter may materially harm our business and financial condition, and frustrate any commercialization efforts for Acetavance. We do
not yet have agreements established regarding commercial supply of Omigard and may not be able to establish or maintain commercial manufacturing arrangements on commercially reasonable terms for Omigard, or any other product candidates that we may
in-license or acquire. We are currently negotiating with suppliers for the commercial supply of the active pharmaceutical ingredient, or API, for Acetavance and for the commercial supply of API and finished drug product for Omigard. We do not have
any long-term commitments from our suppliers of clinical trial material or guaranteed prices for our product candidates or placebos, and we do not have alternate manufacturing plans in place at this time. If we need to change to other manufacturers
or significantly change the manufacturing processes for our product candidates, we may be required to repeat or perform additional pre-clinical or clinical testing, which could increase our costs and cause delays in our ability to obtain regulatory
approvals. Additionally, the FDA and comparable international regulatory authorities must approve these manufacturers facilities and processes prior to our use, which would require new testing and compliance inspections, and the new
manufacturers would have to be educated in, or independently develop, the processes necessary for the production of our products. If there are delays in obtaining approvals of any new manufacturers, we could experience delays in the availability of
our product candidates to complete our clinical trials or for commercial distribution.

The manufacture of pharmaceutical
products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, particularly in
scaling up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the product candidate and quality assurance testing, shortages of qualified personnel, as well as compliance
with strictly enforced federal, state and foreign regulations. Our manufacturers may not perform as agreed. If our manufacturers were to encounter any of these difficulties, our ability to provide product candidates to patients in our clinical
trials would be jeopardized.

In addition, all manufacturers of our product candidates must comply with cGMP requirements
enforced by the FDA through its facilities inspection program. These requirements include quality control, quality assurance and the maintenance of records and documentation. Manufacturers of our product candidates may be unable to comply with these
cGMP requirements and with other FDA, state and foreign regulatory requirements. We have little control over our manufacturers compliance with these regulations and standards. A failure to comply with these requirements may result in fines and
civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any quantities supplied is compromised due to our manufacturers failure to
adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our product candidates.

Our future growth depends on our ability to identify and acquire or in-license products and if we do not successfully identify and acquire or in-license related product candidates or integrate them into our
operations, we may have limited growth opportunities.

We in-licensed the rights to each of our two current product
candidates, Acetavance and Omigard, from third parties who conducted the initial development of each product candidate. An important part of our business strategy

##### Table of Contents

is to continue to develop a pipeline of product candidates by acquiring or in-licensing products, businesses or technologies that we believe are a strategic
fit with our focus on the hospital marketplace. Future in-licenses or acquisitions, however, may entail numerous operational and financial risks, including:



| |  |  | exposure to unknown liabilities;
| | - |  | --------------------------------



| |  |  | disruption of our business and diversion of our managements time and attention to develop acquired products or technologies;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | higher than expected acquisition and integration costs;
| | - |  | -------------------------------------------------------



| |  |  | increased amortization expenses;
| | - |  | --------------------------------



| |  |  | difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | inability to retain key employees of any acquired businesses.
| | - |  | -------------------------------------------------------------

We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. In
particular, we may compete with larger pharmaceutical companies and other competitors in our efforts to establish new collaborations and in-licensing opportunities. These competitors likely will have access to greater financial resources than us and
may have greater expertise in identifying and evaluating new opportunities. Moreover, we may devote resources to potential acquisitions or in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of
such efforts.

We will need to increase the size of our organization, and we may experience difficulties in managing growth.

As of March 31, 2008, we had 47 full-time employees. We will need to continue to expand our managerial, operational,
financial and other resources in order to manage and fund our operations and clinical trials, continue our development activities and commercialize our product candidates. Our management, personnel, systems and facilities currently in place may not
be adequate to support this future growth. Our need to effectively manage our operations, growth and various projects requires that we:



| |  |  | manage our clinical trials effectively, including our ongoing Phase III clinical program for Acetavance, which is being conducted at numerous clinical trial
sites in the U.S., and our Phase III clinical trial of Omigard, which is being conducted at numerous clinical sites in the U.S. and Europe;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | manage our internal development efforts effectively while carrying out our contractual obligations to licensors and other third parties; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continue to improve our operational, financial and management controls, reporting systems and procedures.
| | - |  | ---------------------------------------------------------------------------------------------------------

We may be unable to successfully implement these tasks on a larger scale and, accordingly, may not achieve our development and
commercialization goals.

We may not be able to manage our business effectively if we are unable to attract and retain key personnel.

We may not be able to attract or retain qualified management and scientific and clinical personnel in the future
due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Diego, California area. If we are not able to attract and retain necessary personnel to

##### Table of Contents

accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability
to raise additional capital and our ability to implement our business strategy.

Our industry has experienced a high rate
of turnover of management personnel in recent years. We are highly dependent on the product acquisition, development, regulatory and commercialization expertise of our senior management, particularly Theodore R. Schroeder, our President and Chief
Executive Officer, James B. Breitmeyer, M.D., Ph.D., our Executive Vice President, Development and Chief Medical Officer, and William R. LaRue, our Senior Vice President, Chief Financial Officer, Treasurer and Assistant Secretary. If we
lose one or more of these key employees, our ability to successfully implement our business strategy could be seriously harmed. Replacing key employees may be difficult and may take an extended period of time because of the limited number of
individuals in our industry with the breadth of skills and experience required to develop, gain regulatory approval of and commercialize products successfully. Competition to hire from this limited pool is intense, and we may be unable to hire,
train, retain or motivate these additional key personnel. Although we have employment agreements with Mr. Schroeder, Dr. Breitmeyer and Mr. LaRue, these agreements are terminable at will at any time with or without notice and,
therefore, we may not be able to retain their services as expected.

In addition, we have scientific and clinical advisors
who assist us in our product development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us, or may have
arrangements with other companies to assist in the development of products that may compete with ours.

We face potential product
liability exposure, and if successful claims are brought against us, we may incur substantial liability for a product candidate and may have to limit its commercialization.

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approval expose us to the
risk of product liability claims. Product liability claims might be brought against us by consumers, health care providers or others using, administering or selling our products. If we cannot successfully defend ourselves against these claims, we
will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:



| |  |  | withdrawal of clinical trial participants;
| | - |  | ------------------------------------------



| |  |  | termination of clinical trial sites or entire trial programs;
| | - |  | -------------------------------------------------------------



| |  |  | decreased demand for our product candidates;
| | - |  | --------------------------------------------



| |  |  | impairment of our business reputation;
| | - |  | --------------------------------------



| |  |  | costs of related litigation;
| | - |  | ----------------------------



| |  |  | substantial monetary awards to patients or other claimants;
| | - |  | -----------------------------------------------------------



| |  |  | loss of revenues; and
| | - |  | ---------------------



| |  |  | the inability to commercialize our product candidates.
| | - |  | ------------------------------------------------------

We have obtained limited product liability insurance coverage for our clinical trials with a $15.0 million annual aggregate coverage limit and additional amounts in selected foreign
countries where we are conducting clinical trials. However, our insurance coverage may not reimburse us or may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly
expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. We intend to expand our insurance coverage to include the sale of
commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. On occasion, large judgments
have been awarded in class action lawsuits based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against us could cause our stock price to fall and, if judgments exceed our insurance
coverage, could decrease our cash and adversely affect our business.

Recent proposed legislation may permit re-importation of drugs from foreign countries into the
U.S., including foreign countries where the drugs are sold at lower prices than in the U.S., which could materially adversely affect our operating results and our overall financial condition.

Legislation has been introduced in Congress that, if enacted, would permit more widespread re-importation of drugs from foreign countries
into the U.S., which may include re-importation from foreign countries where the drugs are sold at lower prices than in the U.S. Such legislation, or similar regulatory changes, could decrease the price we receive for any approved products which, in
turn, could materially adversely affect our operating results and our overall financial condition. For example, BMS markets Acetavance in Europe and other countries principally under the brand name Perfalgan. Although Perfalgan is not labeled for
sale in the U.S. and we have an exclusive license from BMS and its licensor to develop and sell Acetavance in the U.S., it is possible that hospitals and other users may in the future seek to import Perfalgan rather than purchase Acetavance in
the U.S. for cost-savings or other reasons. We would not receive any revenues from the importation and sale of Perfalgan into the U.S.

Our business involves the use of hazardous materials and we and our third-party manufacturers must comply with environmental laws and regulations, which can be expensive and restrict how we do business.

Our third-party manufacturers activities and, to a lesser extent, our own activities involve the controlled storage, use and
disposal of hazardous materials, including the components of our product candidates and other hazardous compounds. We and our manufacturers are subject to federal, state and local laws and regulations governing the use, manufacture, storage,
handling and disposal of these hazardous materials. Although we believe that the safety procedures for handling and disposing of these materials comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of
accidental contamination or injury from these materials. In the event of an accident, state or federal authorities may curtail our use of these materials and interrupt our business operations.

Our business and operations would suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems are vulnerable to damage from computer viruses,
unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Any system failure, accident or security breach that causes interruptions in our operations could result in a material disruption of our drug
development programs. For example, the loss of clinical trial data from completed or ongoing clinical trials for Acetavance or Omigard could result in delays in our regulatory approval efforts and significantly increase our costs to recover or
reproduce the data. To the extent that any disruption or security breach results in a loss or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we may incur liability and the further
development of our product candidates may be delayed.

Risks Related to Intellectual Property

The patent rights that we have in-licensed covering Acetavance are limited to a specific intravenous formulation of acetaminophen, and our
market opportunity for this product candidate may be limited by the lack of patent protection for the active ingredient itself and other formulations that may be developed by competitors.

The active ingredient in Acetavance is acetaminophen. Patent protection for the acetaminophen molecule itself in the territories
licensed to us, which include the U.S. and Canada, is not available. As a result, competitors who obtain the requisite regulatory approval can offer products with the same active ingredient as Acetavance so long as the competitors do not
infringe any process or formulation patents that we have in-licensed from BMS and its licensor, SCR Pharmatop. We are aware of a number of third-party patents in the U.S. that claim methods of making acetaminophen. If a supplier of the API for
our Acetavance product candidate is found to infringe any of these method patents covering acetaminophen, our supply of the API could be delayed and we may be required to locate an alternative supplier. We are also aware of several U.S. and
Canadian patents and patent applications covering various potential injectable formulations of acetaminophen as well as methods of making and using these potential formulations. For example, Injectapap, a liquid formulation of acetaminophen for
intramuscular injection, was approved by the FDA for the reduction of fever in adults in March 1986, although it was subsequently withdrawn from the market by McNeil Pharmaceutical in July 1986.

##### Table of Contents

The number of patents and patent applications covering products in the same field
as Acetavance indicates that competitors have sought to develop and may seek to market competing formulations that may not be covered by our licensed patents and patent applications. In addition, the Canadian patent applications that we have
in-licensed have yet to be examined by the Canadian Patent Office. Thus, they may issue with claims that cover less than the corresponding in-licensed U.S. patents, or simply not issue at all. The commercial opportunity for our Acetavance
product candidate could be significantly harmed if competitors are able to develop an alternative formulation of acetaminophen outside the scope of our in-licensed patents.

The patent rights that we have in-licensed covering Omigard are limited in scope and limited to specific territories.

We have an exclusive license from Migenix for Omigard in North America and Europe for the licensed field, although currently there are
issued patents only in the U.S. and certain European countries. Canadian applications are pending; however, the claims that ultimately issue in Canada may be narrower than the protection obtained in the U.S. and Europe or may simply not issue at
all. In addition, no patent protection has been sought in Mexico. Accordingly, the manufacture, sale and use of Omigard in Mexico by a competitor cannot be prevented. Furthermore, there are third-party patents covering analogs of omiganan and
Migenix has patented analogs of omiganan that are not licensed to us. It is possible that competitors having rights to these patents may develop competing products having the same, similar or better efficacy compared to Omigard.

Furthermore, our license agreement with Migenix only covers the use of Omigard and other formulations of omiganan for the licensed field,
which is the topical administration to a burn or a surgical wound site for the treatment or prevention in humans of burn-related or surgery-related infections, and the topical administration to a device or the site around the device for the
treatment or prevention in humans of device-related infections, including local catheter site infections and catheter-related blood stream infections. Thus, Migenix or third-party licensees of Migenix may be able to market Omigard for other uses,
including treatment of non-surgery related wound infections. We may be unable to prevent physicians from using any such competitive Omigard product off-label for the field licensed to us.

We depend on our licensors for the maintenance and enforcement of our intellectual property and have limited control, if any, over the amount or
timing of resources that our licensors devote on our behalf.

We depend on our licensors, BMS, SCR Pharmatop, and
Migenix, to protect the proprietary rights covering Acetavance and Omigard. Regarding Acetavance, either BMS or its licensor, SCR Pharmatop, depending on the patent or application, is responsible for maintaining issued patents and
prosecuting patent applications. Regarding Omigard, Migenix is responsible for maintaining issued patents and prosecuting patent applications. We have limited, if any, control over the amount or timing of resources that our licensors devote on our
behalf or the priority they place on maintaining these patent rights and prosecuting these patent applications to our advantage. If our licensors experience serious difficulties related to their overall business or financial stability, they may be
unwilling or unable to continue to expend the financial resources required to prosecute these patent applications. SCR Pharmatop is under a contractual obligation to BMS to diligently prosecute their patent applications and allow BMS the opportunity
to consult, review and comment on patent office communications. However, we cannot be sure that SCR Pharmatop will perform as required. Should BMS decide it no longer wants to maintain any of the patents licensed to us, BMS is required to afford us
the opportunity to do so at our expense. However, we cannot be sure that BMS will perform as required. If BMS does not perform, and if we do not assume the maintenance of the licensed patents in sufficient time to make required payments or filings
with the appropriate governmental agencies, we risk losing the benefit of all or some of those patent rights. For patents and applications licensed from Migenix, Migenix is obligated to use commercially reasonable efforts to obtain and maintain
patent rights covering Omigard in North America and Europe. If Migenix intends to abandon prosecution or maintenance of any patents or applications, they are obligated to notify us, and at that time, we will be granted an opportunity to maintain and
prosecute the patents and applications at our expense. In such a case, Migenix is required to transfer all necessary rights and responsibilities to facilitate our maintenance and prosecution of the patents and applications. Similar to BMS, however,
we cannot be certain that Migenix will perform its contractual obligations as required or that we will be able to adequately assume the prosecution or maintenance of the Omigard-related patents and applications.

As part of a financing transaction, Migenix has pledged as collateral to its lenders the
patents and patent applications covering Omigard. While we believe our license agreement with Migenix would survive any foreclosure on these patents and patent applications, we cannot be sure that the lenders will have adequate expertise or
resources to properly perform Migenixs obligations to us under the license agreement, including maintaining and prosecuting the patents and patent applications.

While we intend to take actions reasonably necessary to enforce our patent rights, we depend, in part, on our licensors to protect a substantial portion of our proprietary rights. In the case of
the Acetavance patents, BMS has the first right to prosecute a third-party infringement of the SCR Pharmatop patents, and has the sole right to prosecute third-party infringement of the BMS patents. We will have the ability to cooperate with
BMS in third-party infringement suits involving the SCR Pharmatop patents. It is possible that SCR Pharmatop or BMS could take some action or fail to take some action that could harm the SCR Pharmatop patents. In certain instances, we may be allowed
to pursue the infringement claim ourselves. With respect to Omigard, we have the first right to prosecute a third-party for infringement of the in-licensed Migenix patents provided the infringing activities are in North America or Europe and relate
primarily to the licensed field of use. Migenix is obligated to reasonably cooperate with any such suit.

Our licensors may
also be notified of alleged infringement and be sued for infringement of third-party patents or other proprietary rights. We may have limited, if any, control or involvement over the defense of these claims, and our licensors could be subject to
injunctions and temporary or permanent exclusionary orders in the U.S. or other countries. Our licensors are not obligated to defend or assist in our defense against third-party claims of infringement. We have limited, if any, control over the
amount or timing of resources, if any, that our licensors devote on our behalf or the priority they place on defense of such third-party claims of infringement. Finally, Migenix is not obligated to defend or assist in our defense of a third-party
infringement suit relating to our Omigard product candidate; however, Migenix has the right to control the defense and settlement that relates to the validity and enforceability of claims in the in-licensed Migenix patents.

For a third-party challenge to the SCR Pharmatop in-licensed patents relating to Acetavance, we will have some ability to
participate in either SCR Pharmatops or BMS defense thereof. In the case that neither party elects to defend the third-party challenge, we may have the opportunity to defend it. For a third-party challenge to the in-licensed BMS patents
relating to Acetavance, BMS has the sole right to defend such challenge. If it chooses not to, we may have the right to renegotiate or terminate the license regarding the in-licensed BMS patents.

Because of the uncertainty inherent in any patent or other litigation involving proprietary rights, we or our licensors may not be
successful in defending claims of intellectual property infringement by third parties, which could have a material adverse affect on our results of operations. Regardless of the outcome of any litigation, defending the litigation may be expensive,
time-consuming and distracting to management.

Because it is difficult and costly to protect our proprietary rights, we may not be
able to ensure their protection.

Our commercial success will depend in part on obtaining and maintaining patent
protection and trade secret protection for Acetavance, Omigard or any other product candidates that we may in-license or acquire and the methods we use to manufacture them, as well as successfully defending these patents against third-party
challenges. We will only be able to protect our technologies from unauthorized use by third parties to the extent that valid and enforceable patents or trade secrets cover them.

The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual
questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in pharmaceutical or biotechnology patents has emerged to date in the U.S. The patent situation outside the U.S. is even
more uncertain. Changes in either the patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or
enforced in our patents or in third-party patents.

The degree of future protection for our proprietary rights is
uncertain, because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

| |  |  | patents of others may have an adverse effect on our business.
| | - |  | -------------------------------------------------------------

Patent applications in the U.S. are maintained in confidence for at least 18 months after their earliest effective filing date. Consequently, we cannot be certain that our licensors were the
first to invent or the first to file patent applications on some of our product candidates. In the event that a third party has also filed a U.S. patent application relating to our product candidates or a similar invention, we may have to
participate in interference proceedings declared by the U.S. Patent and Trademark Office to determine priority of invention in the U.S. The costs of these proceedings could be substantial and it is possible that our efforts would be
unsuccessful, resulting in a material adverse effect on our U.S. patent position. Furthermore, we may not have identified all U.S. and foreign patents or published applications that affect our business either by blocking our ability to
commercialize our drugs or by covering similar technologies that affect our drug market.

In addition, some countries,
including many in Europe, do not grant patent claims directed to methods of treating humans, and in these countries patent protection may not be available at all to protect our product candidates. Even if patents issue, we cannot guarantee that the
claims of those patents will be valid and enforceable or provide us with any significant protection against competitive products, or otherwise be commercially valuable to us.

We also rely on trade secrets to protect our technology, particularly where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect.
While we use reasonable efforts to protect our trade secrets, our licensors, employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing
a claim that a third party illegally obtained and is using our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. are sometimes less willing to protect trade secrets. Moreover, our
competitors may independently develop equivalent knowledge, methods and know-how.

If our licensors or we fail to obtain or
maintain patent protection or trade secret protection for Acetavance, Omigard or any other product candidate we may in-license or acquire, third parties could use our proprietary information, which could impair our ability to compete in the
market and adversely affect our ability to generate revenues and achieve profitability.

If we are sued for infringing intellectual
property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in any litigation would harm our business.

Our ability to develop, manufacture, market and sell Acetavance, Omigard or any other product candidates that we may in-license or acquire depends upon our ability to avoid infringing the proprietary rights of
third parties. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the general fields of pain treatment and prevention of infections and cover the use of numerous compounds and
formulations in our targeted markets. For instance, there is a patent in force in various European countries, with claims that, if valid, may be broad enough in scope to cover the formulation of our Omigard product candidate. It is possible that we
may determine it prudent to seek a license to this European patent in order to avoid potential



40

##### Table of Contents

litigation and other disputes. We cannot be sure that a license would be available to us on commercially reasonable terms, or at all. According to the U.S.
Patent and Trademark Office, a patent application corresponding to this European patent was also filed in the U.S. but has been abandoned. There is also a patent application pending in Canada that corresponds to the European
patent. Because this patent application has not issued, it is too early to tell if the claims of this application will present similar issues for Omigard in Canada. However, similar to the European patent, if the Canadian patent application issues
with a scope that is broad enough to cover our Omigard product candidate and we are unable to assert successful defenses to any patent claims, we may be unable to commercialize Omigard in Canada, or may be required to expend substantial sums to
obtain a license to the other partys patent. While we believe there may be multiple grounds to challenge the validity of the European patent, and these grounds may be applicable to the Canadian application should it issue as a patent, the
outcome of any litigation relating to this European patent and the Canadian patent application, or any other patents or patent applications, is uncertain and participating in such litigation would be expensive, time-consuming and distracting to
management. Because of the uncertainty inherent in any patent or other litigation involving proprietary rights, we and Migenix may not be successful in defending intellectual property claims by third parties, which could have a material adverse
affect on our results of operations. Regardless of the outcome of any litigation, defending the litigation may be expensive, time-consuming and distracting to management. In addition, because patent applications can take many years to issue, there
may be currently pending applications, unknown to us, which may later result in issued patents that Acetavance or Omigard may infringe. There could also be existing patents of which we are not aware that Acetavance or Omigard may inadvertently
infringe.

There is a substantial amount of litigation involving patent and other intellectual property rights in the
biotechnology and biopharmaceutical industries generally. If a third party claims that we infringe on their products or technology, we could face a number of issues, including:



| |  |  | infringement and other intellectual property claims which, with or without merit, can be expensive and time consuming to litigate and can divert
managements attention from our core business;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | substantial damages for past infringement which we may have to pay if a court decides that our product infringes on a competitors patent;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a court prohibiting us from selling or licensing our product unless the patent holder licenses the patent to us, which it is not required to do;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if a license is available from a patent holder, we may have to pay substantial royalties or grant cross licenses to our patents; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesigning our processes so they do not infringe, which may not be possible or could require substantial funds and time.
| | - |  | -------------------------------------------------------------------------------------------------------------------------

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed
at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although no claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently or otherwise used
or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial
costs and be a distraction to management.

Risks Related to Our Finances and Capital Requirements

We have incurred significant operating losses since our inception and anticipate that we will incur continued losses for the foreseeable future.

We are a development stage company with a limited operating history. We have focused primarily on in-licensing and
developing our two product candidates, Acetavance and Omigard, with the goal of supporting



41

##### Table of Contents

regulatory approval for these product candidates. We have incurred losses in each year since our inception in May 2004, including net losses of $51.7
million, $52.2 million and $7.7 million for the years ended December 31, 2007, 2006 and 2005, respectively. As of March 31, 2008, we had an accumulated deficit of $128.1 million. These losses, among other things, have had
and will continue to have an adverse effect on our stockholders equity and working capital. We expect our development expenses as well as clinical product manufacturing expenses to increase in connection with our ongoing and planned
Phase III clinical trials and any additional clinical trials that we may be required to conduct in order to support regulatory approvals, additional indications or dosages for our product candidates. In addition, if we obtain regulatory
approval for Acetavance or Omigard, we expect to incur significant sales, marketing and outsourced manufacturing expenses as well as continued development expenses. As a result, we expect to continue to incur significant and increasing
operating losses for the foreseeable future. Because of the numerous risks and uncertainties associated with developing pharmaceutical products, we are unable to predict the extent of any future losses or when we will become profitable, if at all.

We currently have no source of revenue and may never be profitable.

Our ability to become profitable depends upon our ability to generate revenue. To date, we have not generated any revenue from our
development stage product candidates, and we do not know when, or if, we will generate any revenue. Our ability to generate revenue depends on a number of factors, including, but not limited to, our ability to:



| |  |  | successfully complete our ongoing and future clinical trials of Acetavance and Omigard;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | obtain regulatory approval for either of our two product candidates or any other product candidate that we may in-license or acquire;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | assuming these regulatory approvals are received, manufacture commercial quantities of our product candidates at acceptable cost levels; and

| |  |  | successfully market and sell any approved products.
| | - |  | ---------------------------------------------------

Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product. We also do not
anticipate that we will achieve profitability for at least several years after generating material revenues, if ever. If we are unable to generate revenues, we will not become profitable and may be unable to continue operations without continued
funding.

Our short operating history makes it difficult to evaluate our business and prospects.

We were incorporated in May 2004 and have only been conducting operations with respect to our Acetavance product candidate
since March 2006 and our Omigard product candidate since July 2004. Our operations to date have been limited to organizing and staffing our company, in-licensing our two product candidates and conducting product development activities,
including clinical trials and manufacturing development activities, for our two product candidates. We have not yet demonstrated an ability to obtain regulatory approval for or successfully commercialize a product candidate. Consequently, any
predictions about our future performance may not be as accurate as they could be if we had a history of successfully developing and commercializing pharmaceutical products.

We will need additional funding and may be unable to raise capital when needed, which would force us to delay, reduce or eliminate our product
development programs or commercialization efforts.

Developing products for use in the hospital setting, conducting
clinical trials, establishing outsourced manufacturing relationships and successfully manufacturing and marketing drugs that we may develop is expensive. We will need to raise additional capital to:



| |  |  | fund our operations and continue to conduct adequate and well-controlled clinical trials to provide clinical data to support regulatory approval of marketing
applications;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continue our development activities;
| | - |  | ------------------------------------

| |  |  | qualify and outsource the commercial-scale manufacturing of our products under cGMP; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | commercialize Acetavance, Omigard or any other product candidates that we may in-license or acquire, if any of these product candidates receive regulatory
approval.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe that our existing cash and cash equivalents, including the net proceeds from our
initial public offering completed in the fourth quarter of 2006 and our registered direct offering in the first quarter of 2008, will be sufficient to meet our projected operating requirements, at a minimum, through the next twelve months. We have
based this estimate on assumptions that may prove to be wrong and we could spend our available financial resources faster than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:



| |  |  | the rate of progress and cost of our clinical trials and other product development programs for Acetavance, Omigard and any other product candidates that we
may in-license or acquire;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights associated with our product candidates;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cost and timing of completion of an outsourced commercial manufacturing supply for each product candidate;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | the costs and timing of regulatory approval;
| | - |  | --------------------------------------------



| |  |  | the costs of establishing sales, marketing and distribution capabilities;
| | - |  | -------------------------------------------------------------------------



| |  |  | the effect of competing technological and market developments; and
| | - |  | ------------------------------------------------------------------



| |  |  | the terms and timing of any collaborative, licensing, co-promotion or other arrangements that we may establish.
| | - |  | ---------------------------------------------------------------------------------------------------------------

Future capital requirements will also depend on the extent to which we acquire or invest in additional complementary businesses, products
and technologies, but we currently have no commitments or agreements relating to any of these types of transactions.

Until
we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements, as well as through interest
income earned on cash and investment balances. We cannot be certain that additional funding will be available on acceptable terms, or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or
more of our development programs or our commercialization efforts.

Our quarterly operating results may fluctuate significantly.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results
will be affected by numerous factors, including:



| |  |  | the timing of milestone payments required under our license agreements for Acetavance and Omigard;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | our execution of other collaborative, licensing or similar arrangements, and the timing of payments we may make or receive under these arrangements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our addition or termination of clinical trials or funding support;
| | - |  | ------------------------------------------------------------------



| |  |  | variations in the level of expenses related to our two existing product candidates or future development programs;
| | - |  | ------------------------------------------------------------------------------------------------------------------

If our quarterly or annual operating results fall below the expectations of investors or
securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly or annual fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believe that
quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

Raising additional funds by issuing securities may cause dilution to existing stockholders and raising funds through lending and licensing arrangements may restrict our operations or require us to relinquish
proprietary rights.

To the extent that we raise additional capital by issuing equity securities, our existing
stockholders ownership will be diluted. If we raise additional funds through licensing arrangements, it may be necessary to relinquish potentially valuable rights to our potential products or proprietary technologies, or grant licenses on
terms that are not favorable to us. Any debt financing we enter into may involve covenants that restrict our operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of our assets
as well as prohibitions on our ability to create liens, pay dividends, redeem our stock or make investments. For example, in February 2006, we entered into a $7.0 million loan and security agreement with Silicon Valley Bank and Oxford
Finance Corporation, and in December 2007, we amended this agreement and secured an additional $15.0 million loan from the same parties and GE Business Financial Services Inc. These loan and security agreements contain a variety of
affirmative and negative covenants, including required financial reporting, limitations on the disposition of assets other than in the ordinary course of business, limitations on the incurrence of additional debt and other requirements. To secure
our performance of our obligations under the loan and security agreement, we pledged substantially all of our assets other than intellectual property assets, to the lenders. Our failure to comply with the covenants in the loan and security agreement
could result in an event of default that, if not cured or waived, could result in the acceleration of all or a substantial portion of our debt.

We will continue to incur significant increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses under the Sarbanes-Oxley Act of 2002, as well as rules
subsequently implemented by the SEC and The NASDAQ Stock Market LLC. These rules impose various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in
corporate governance practices. Our management and other personnel have devoted and will continue to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our legal and financial
compliance costs and make some activities more time-consuming and costly. For example, these rules and regulations make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept
reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors, our board
committees or as executive officers.

The Sarbanes-Oxley Act of 2002 requires, among other things, that we maintain
effective internal controls for financial reporting and disclosure controls and procedures. As a result, we are required to perform an evaluation of our internal controls over financial reporting to allow management to report on the effectiveness of
those controls, as required by Section 404 of the Sarbanes-Oxley Act. Additionally, our independent auditors are required to perform a similar evaluation and report on the effectiveness of our internal controls over financial reporting. These
efforts to comply with Section 404 and related regulations has required, and continues to require, the commitment of significant financial and managerial resources. While we anticipate maintaining the integrity of our internal controls over
financial reporting and all other aspects of Section 404, we cannot be certain that a material weakness will not

be identified when we test the effectiveness of our control systems in the future. If a material weakness is identified, we could be subject to sanctions or
investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources, costly litigation or a loss of public confidence in our internal controls, which could have an adverse effect on
the market price of our stock.

Risks Relating to Securities Markets and Investment in Our Stock

There may not be a viable public market for our common stock.

Our common stock had not been publicly traded prior to our initial public offering, which was completed in October 2006, and an active trading market may not develop or be sustained. We have
never declared or paid any cash dividends on our capital stock, and we currently intend to retain all available funds and any future earnings to support operations and finance the growth and development of our business and do not intend to pay cash
dividends on our common stock for the foreseeable future. Furthermore, our amended loan and security agreement with Silicon Valley Bank, Oxford Finance Corporation and GE Business Financial Services Inc. restricts our ability to pay cash dividends.
Therefore, investors will have to rely on appreciation in our stock price and a liquid trading market in order to achieve a gain on their investment. The market prices for securities of biotechnology and pharmaceutical companies have historically
been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. Since our initial public offering in October 2006 through
April 30, 2008, the trading prices for our common stock ranged from a high of $18.55 to a low of $4.84.

Future sales of our
common stock may cause our stock price to decline.

Persons who were our stockholders prior to the sale of shares
in our initial public offering continue to hold a substantial number of shares of our common stock that they may now be able to sell in the public market. Significant portions of these shares are held by a small number of stockholders. Sales by our
current stockholders of a substantial number of shares, or the expectation that such sales may occur, could significantly reduce the market price of our common stock. Moreover, the holders of a substantial number of shares of common stock may have
rights, subject to certain conditions, to require us to file registration statements to permit the resale of their shares in the public market or to include their shares in registration statements that we may file for ourselves or other
stockholders.

We have also registered all common stock that we may issue under our employee benefits plans. As a result,
these shares can be freely sold in the public market upon issuance, subject to restrictions under the securities laws. In addition, our directors and executive officers may in the future establish programmed selling plans under Rule 10b5-1 of
the Securities Exchange Act of 1934, as amended, for the purpose of effecting sales of our common stock. If any of these events cause a large number of our shares to be sold in the public market, the sales could reduce the trading price of our
common stock and impede our ability to raise future capital.

We expect that the price of our common stock will fluctuate
substantially.

The market price of our common stock is likely to be highly volatile and may fluctuate
substantially due to many factors, including:



| |  |  | the results from our clinical trial programs, including our ongoing Phase III clinical program for Acetavance and our Phase III clinical trial of
Omigard;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the results of clinical trial programs for Acetavance and Omigard being performed by others;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | FDA or international regulatory actions, including failure to receive regulatory approval for any of our product candidates;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of any of our product candidates, if approved, to achieve commercial success;
| | - |  | -------------------------------------------------------------------------------------

The realization of any of the risks described in these Risk Factors could have a dramatic and material adverse impact on the
market price of our common stock. In addition, class action litigation has often been instituted against companies whose securities have experienced periods of volatility in market price. Any such litigation brought against us could result in
substantial costs and a diversion of managements attention and resources, which could hurt our business, operating results and financial condition.

Our executive officers and directors and their affiliates may exercise control over stockholder voting matters in a manner that may not be in the best interests of all of our stockholders.

As of March 31, 2008, our executive officers and directors and their affiliates together controlled approximately 47% of our
outstanding common stock. As a result, these stockholders will collectively be able to significantly influence all matters requiring approval of our stockholders, including the election of directors and approval of significant corporate
transactions. The concentration of ownership may delay, prevent or deter a change in control of our company even when such a change may be in the best interests of all stockholders, could deprive our stockholders of an opportunity to receive a
premium for their common stock as part of a sale of our company or our assets, and might affect the prevailing market price of our common stock.

Anti-takeover provisions under our charter documents and Delaware law could delay or prevent a change of control which could limit the market price of our common stock and may prevent or frustrate attempts by our stockholders to
replace or remove our current management.

Our amended and restated certificate of incorporation and amended and
restated bylaws contain provisions that could delay or prevent a change of control of our company or changes in our board of directors that our stockholders might consider favorable. Some of these provisions include:



| |  |  | a board of directors divided into three classes serving staggered three-year terms, such that not all members of the board will be elected at one time;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a prohibition on stockholder action through written consent;
| | - |  | ------------------------------------------------------------



| |  |  | a requirement that special meetings of stockholders be called only by the chairman of the board of directors, the chief executive officer, the president or by a
majority of the total number of authorized directors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | advance notice requirements for stockholder proposals and nominations;
| | - |  | ----------------------------------------------------------------------



46

##### Table of Contents

| |  |  | a requirement of approval of not less than 66 2/3% of all outstanding shares of our capital stock entitled to vote to amend any bylaws by stockholder action, or
to amend specific provisions of our certificate of incorporation; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the authority of the board of directors to issue preferred stock on terms determined by the board of directors without stockholder approval.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

In addition, we are governed by the provisions of Section 203 of the Delaware General Corporate
Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware
law could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors, including to delay or impede a merger, tender offer or
proxy contest involving our company. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

We have never paid dividends on our capital stock, and we do not anticipate paying any cash dividends in the foreseeable future.

We have paid no cash dividends on any of our classes of capital stock to date and we currently intend to retain
our future earnings, if any, to fund the development and growth of our business. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. Furthermore, our amended loan and security agreement with Silicon Valley
Bank, Oxford Finance Corporation and GE Business Financial Services Inc. restricts our ability to pay dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We may become involved in securities class action litigation that could divert managements attention and harm our business.

The stock markets have from time to time experienced significant price and volume fluctuations that have affected
the market prices for the common stock of pharmaceutical companies. These broad market fluctuations may cause the market price of our common stock to decline. In the past, securities class action litigation has often been brought against a company
following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant stock price volatility in recent years. We may become involved in
this type of litigation in the future. Litigation often is expensive and diverts managements attention and resources, which could adversely affect our business.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

Recent Sales of Unregistered Securities

Not applicable.

Use of Proceeds

Our initial public
offering of common stock was effected through a Registration Statement on Form S-1 (File No. 333-135821) that was declared effective by the SEC on October 24, 2006, which registered an aggregate of 6,900,000 shares of our
common stock. On October 24, 2006, 6,000,000 shares of common stock were sold on our behalf at an initial public offering price of $9.00 per share, for an aggregate gross offering price of $54.0 million, managed by Merrill
Lynch & Co., Deutsche Bank Securities, Pacific Growth Equities, LLC and JMP Securities. On November 13, 2006, in connection with the exercise of the underwriters over-allotment option, 900,000 additional shares of common stock
were sold on our behalf at the initial public offering price of $9.00 per share, for an aggregate gross offering price of $8.1 million. Following the sale of the 6,900,000 shares, the offering terminated. As part of the transaction,
we paid to the underwriters underwriting discounts totaling approximately $4.3 million in connection with the offering. In addition, we incurred additional offering costs of $1.9 million in connection with the offering, which when added to
the underwriting discounts paid by us, amounts to total costs of $6.2 million. Thus, the net offering proceeds to us, after deducting underwriting discounts and offering costs, were $55.9 million. No offering expenses were paid directly or
indirectly to any of our directors or officers (or their associates) or persons owning ten percent or more of any class of our equity securities or to any other affiliates.

On November 30, 2007, we filed a shelf registration statement on Form S-3 (File
No. 333-147721) that was declared effective by the SEC on December 11, 2007. This shelf registration statement on Form S-3 allows us to sell shares of our common stock from time to time in one or more offerings, up to an aggregate offering
price of $100.0 million. On February 14, 2008, we entered into common stock purchase agreements with certain investors relating to a registered direct offering of up to 9,240,307 shares of our common stock at a purchase price of $5.34 per
share, which was the last reported closing price on the Nasdaq Global Market on February 14, 2008. On February 20, 2008, we completed the sale of these shares for gross proceeds of $49.3 million. Our net proceeds from the sale was
approximately $49.1 million after deducing the offering costs which included legal, accounting and printing costs, and various other fees associated with the registering and listing of the shares of our common stock sold in the offering.

As of March 31, 2008, we had used approximately $58.6 million of the net proceeds we received from our initial public
offering and registered direct offering to fund (i) clinical trials for Acetavance and Omigard and other research and development activities; (ii) capital expenditures, including equipment associated with the manufacturing
of Acetavance and Omigard; and (iii) working capital and other general corporate purposes. We may also use a portion of the net proceeds to in-license, acquire or invest in complementary businesses or products. Pursuant to the common stock
purchase agreements with the investors in our registered direct offering completed in February 2008, unless otherwise approved by the holders of a majority of the stock issued in such offering and then held by such investor, the $49.1 million net
proceeds we received from the sale of the securities is limited in its use to (i) funding the clinical and preclinical development of our product candidates, including the funding of additional Phase III clinical trials to support the safety
and efficacy of Acetavance in acute pain, but only if we decide to conduct such trials following any communications with the FDA, and any changes to our ongoing clinical trial of Acetavance in laparoscopic surgery, as appropriate, and (ii) for
general corporate purposes, but only to the extent that the additional Acetavance clinical trials, or modifications to the ongoing clinical trial of Acetavance, as described in clause (i) of this sentence, have been fully funded or amounts
required for those items have been reserved. We cannot specify with certainty all of the particular uses for the net proceeds from our initial public offering. The amount and timing of our expenditures will depend on several factors, including the
progress of our clinical trials and commercialization efforts as well as the amount of cash used in our operations. Accordingly, our management will have broad discretion in the application of the net proceeds.
