NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1.
THE COMPANY

MAP Pharmaceuticals, Inc., incorporated in the state of Delaware, originally was formed as a limited liability
company on July 3, 2003 and converted to a corporation on December 11, 2003. Our goal is to use proprietary inhalation technologies to enhance the therapeutic benefits and commercial attractiveness of proven drugs while minimizing risk by
capitalizing on their known safety, efficacy and commercialization history. Our current focus is to advance the development of our Phase 3 product candidate, LEVADEX, formerly known as MAP0004, a proprietary orally inhaled version of
dihydroergotamine for the potential treatment of migraine. We are in the development stage and since inception have devoted substantially all of our efforts to research and development, raising capital and recruiting personnel.

We have incurred losses and negative cash flow since our inception in July 2003. We will continue to incur losses until we generate
sufficient revenue to offset our expenses, and we anticipate that we will continue to incur net losses for the next several years. We believe that our existing cash, cash equivalents and short-term investments will be sufficient to fund our
projected operating requirements for at least 12 months. We will need substantial additional capital in the future in order to complete the development and potential commercialization of LEVADEX and to fund the development and commercialization of
any future product candidates. Prior to achieving profitable operations, we intend to continue to fund operations through public or private financings, strategic partnerships or other arrangements. Such funding, if needed, may not be available on
favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

We have prepared the accompanying interim condensed consolidated financial statements in accordance with accounting principles generally
accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements and accompanying notes do not include all of the information and
disclosures required by generally accepted accounting principles for complete financial statements. The financial statements include all adjustments (consisting of normal recurring adjustments) that management believes are necessary for the fair
statement of the balances and results for the periods presented. These interim financial statement results are not necessarily indicative of the results to be expected for the full fiscal year or any future interim period.

The year-end condensed balance sheet at December 31, 2009 was derived from audited financial statements, but do not include all the
disclosures required by accounting principles generally accepted in the United States. The financial statements and related disclosures have been prepared with the presumption that users of the interim financial statements have read or have access
to the audited financial statements for the preceding fiscal year. Accordingly, these financial statements should be read in conjunction with the audited financial statements and notes thereto contained in our Form 10-K for the year ended
December 31, 2009.

Comprehensive Loss

We report comprehensive income (loss) in accordance with ASC 220 Reporting Comprehensive Income. Components of other comprehensive
income (loss), including unrealized gains (losses) on our available-for-sale securities, are included in total comprehensive loss.

Net Loss per Share

Basic net loss per share is computed by dividing net loss attributed to common stockholders by the weighted average number of common
shares outstanding during the period. Our potential dilutive shares, which include outstanding common stock options, common stock issuable pursuant to the Employee Stock Purchase Plan, or ESPP, warrants to purchase common stock and performance-based
restricted stock units, have not been included in the computation of diluted net loss per share for all the periods as the result would be anti-dilutive. Such potentially dilutive shares are excluded when the effect would be to reduce a net loss per
share.

The numerator and denominator used in the calculation of basic and diluted net loss per share were as follows (in
thousands, except share and per share amounts):

The following outstanding common stock options, common stock issuable pursuant to the ESPP, warrants to
purchase common stock and performance-based restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect:

Recent Accounting Pronouncements

In September 2009, the FASB ratified Revenue Arrangements with Multiple Deliverables issued as Accounting Standards Update, or ASU,
2009-13 in early October. ASU 2009-13 updates the existing multiple-element arrangements guidance currently included in ASC 605-25, Revenue Recognition  Multiple-Element Arrangements. The revised guidance provides for two significant
changes to the existing multiple-element arrangements guidance. The first relates to the determination of when the individual deliverables included in a multiple-element arrangement may be treated as separate units of accounting. This change is
significant as it will likely result in the requirement to separate more deliverables within an arrangement, ultimately leading to less revenue deferral. The second change modifies the manner in which the transaction consideration is allocated
across the separately identifiable deliverables. These changes are likely to result in earlier recognition of revenue for multiple-element arrangements than under previous guidance. ASU 2009-13 also significantly expands the disclosures required for
multiple-element revenue arrangements. The revised multiple-element arrangements guidance will be effective for the first annual reporting period beginning on or after June 15, 2010, and may be applied retrospectively for all periods presented
or prospectively to arrangements entered into or modified after the adoption date. Early adoption is permitted provided that the revised guidance is retroactively applied to the beginning of the year of adoption. If the guidance is adopted
prospectively, certain transitional disclosures are required for each reporting period in the initial year of adoption. As a result, it is effective for us in the first quarter of fiscal year 2011. We do not believe that the adoption of ASU 2009-13
will have a material impact on our condensed consolidated financial statements.

NOTE 3. LICENSE AND SUPPLY AGREEMENTS

Agreement with AstraZeneca

In December 2008, we entered into an agreement with AstraZeneca AB, or the AstraZeneca Agreement, which became effective in February 2009.
Pursuant to the terms of the AstraZeneca Agreement, we licensed to AstraZeneca global rights to develop and commercialize our proprietary nebulized formulation of UDB, our next generation UDB therapy and certain combination nebulization therapies
for the potential treatment of asthma in children.

In February 2009, under the terms of the AstraZeneca Agreement,
AstraZeneca paid us a nonrefundable upfront cash payment of $40.0 million. On February 23, 2009, we announced top-line results of our initial Phase 3 clinical trial of UDB for the potential treatment of children with asthma. We announced that
the clinical trial did not meet its co-primary endpoints, asthma control as assessed by changes from baseline in nighttime and daytime composite symptom scores, in either of the doses evaluated when compared with placebo.

On July 8, 2009, we received notice from AstraZeneca of the termination of the AstraZeneca Agreement. Effective on the date of
termination, all rights licensed to AstraZeneca in the AstraZeneca Agreement reverted back to us. We were jointly developing UDB with AstraZeneca, and were responsible for executing the development plan. In the third quarter of 2009 we suspended
development of our UDB product candidate.

Total collaboration revenue recognized under the AstraZeneca Agreement was $0 for
the three months ended March 31, 2010, compared to $7.5 million for the same period in 2009, and $54.2 million for the cumulative period from July 3, 2003 (date of inception) to March 31, 2010. The revenue recognized in the first
quarter of 2009 was related to the amortization of a $40.0 million upfront payment received in February 2009 and to reimbursements for UDB-related development expenses, pursuant to the AstraZeneca Agreement.

Agreement with Nektar

Under our June 2004 agreement, as amended, with Nektar Therapeutics UK Limited, or the Nektar Agreement, we were granted a worldwide,
exclusive license, with a right to sublicense, under Nektar patents and know-how, to develop and commercialize any formulation of a form of dihydroergotamine for administration by inhalation using a device. We also agreed to pay royalties at
specified rates based on net sales. As of March 31, 2010, we are required to make future nonrefundable milestone payments of up to $5.0 million related to products currently being developed under the Nektar Agreement, when and if certain
regulatory and commercial milestones are met. We paid $0, $0 and $2.6 million related to milestones for the three months ended March 31, 2010 and 2009 and for the cumulative period from July 3, 2003 (date of inception) to March 31,
2010. Either party may terminate the Nektar Agreement upon a material, uncured default of the other party. We may terminate the Nektar Agreement, with or without cause, at any time upon six months prior written notice.

Agreement with Elan

Under the April 2004 agreement, as amended, with Elan Pharma International Limited, or the Elan Agreement, Elan granted to us a
worldwide, exclusive, sub-licensable license under certain of Elans intellectual property rights related to our UDB product candidate. We also agreed to pay royalties at specified rates based on net sales. As of March 31, 2010, we may be
required to make future nonrefundable milestone payments of up to $16.5 million related to products developed under the Elan Agreement, when and if certain regulatory and commercial milestones under the Elan Agreement are met. We paid $0, $0 and
$4.0 million for the three months ended March 31, 2010 and 2009 and for the cumulative period from July 3, 2003 (date of inception) to March 31, 2010. Either party may terminate the Elan Agreement upon a material, uncured default of
the other party. We may terminate the agreement, with or without cause, at any time upon 90 days prior written notice. We also entered into a services agreement with Elan Drug Delivery International in February 2005, amended subsequently,
which describes the terms and conditions for clinical and commercial supply of product intermediate for our UDB product candidate.

NOTE 4.
FAIR VALUE MEASUREMENTS

On January 1, 2008, we adopted ASC 820 Fair Value Measurements,as it relates to
financial assets and financial liabilities. In February 2008, the FASB delayed the effective date of ASC 820 Fair Value Measurementsfor all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at
fair value in the financial statements on at least an annual basis, until January 1, 2009 for calendar year-end entities. ASC 820 Fair Value Measurementsdefines fair value, establishes a framework for measuring fair value in GAAP and
expands disclosures about fair value measurements.

ASC 820 Fair Value Measurementsdefines fair value as the price that would be
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. This standard is now the single source in GAAP for the definition of fair value, except for the fair value of
leased property as defined in ASC 840 Accounting for Leases,which establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources
(observable inputs) and (2) an entitys own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad
levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy under ASC 820
Fair Value Measurements are described below:



| |  |  | Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy
gives the highest priority to Level 1 inputs.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2: Directly or indirectly observable inputs as of the reporting date through correlation with market data, including quoted prices for similar
assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the
input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3: Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values
are generally determined using pricing models for which the assumptions utilize managements estimates of market participant assumptions.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of
unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value.

Our investment instruments are classified within Level 1 or Level 2 of the
fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments that are generally classified within Level 1
of the fair value hierarchy include money market securities. The types of investments that are generally classified within Level 2 of the fair value hierarchy include U.S. government and agency securities, corporate debt securities and certificates
of deposit.

As of March 31, 2010 and December 31, 2009, financial assets measured and recognized at fair value on a
recurring basis and classified under the appropriate level of the fair value hierarchy as described above were as follows, respectively (in thousands):

Our investments in money market funds are measured at
fair value on a recurring basis. Our money market funds comply with Rule 2a-7 of the Investment Company Act of 1940 and are required to be priced and have a fair value of $1.00 net asset value per share. These money market funds are actively traded
and reported daily through a variety of sources. Due to the structure and valuation required by the Investment Company Act of 1940 regarding Rule 2a-7 funds, the fair value of the money market fund investments is classified as Level 1.

The fair value of the certificates of deposit is classified as Level 2 due to the nature of a contractual restriction in our lease
agreement which limits our ability to liquidate the investment.

The carrying amount for our debt reported in the condensed
consolidated balance sheet as of March 31, 2010 was $12.9 million. Using a discounted cash flow technique that incorporates a market interest rate, we have determined the fair value of our debt to be $12.6 million at March 31, 2010.

Debt

In September 2006, we entered into a $3.0 million loan facility agreement for the purpose of financing equipment purchases, or the
Equipment Loan, and borrowed $1.0 million under this facility. The Equipment Loan bore interest at an annual interest rate of 9.5% and matured in September 2009. The Equipment Loan was fully paid as of September 30, 2009.

In May 2008, we entered into an additional loan agreement, or the 2008 Working Capital
Loan, for $20.0 million, in order to repay an earlier working capital loan and to support general corporate purposes. The 2008 Working Capital Loan bears interest at an annual rate of 9.95%, with an effective rate of approximately 12% after
factoring in a $1.0 million payment due at the termination of this agreement. The 2008 Working Capital Loan had interest-only payments up to and including January 2009, matures in October 2011, and includes customary loan covenants. As of
March 31, 2010, we were in compliance with these loan covenants.

The Equipment Loan amounts were collateralized by our
equipment purchased using such borrowed funds, and the 2008 Working Capital Loan amounts are collateralized by all of our assets, excluding intellectual property.

Our debt consisted of the following (in thousands):

NOTE 6. COMMITMENTS AND CONTINGENCIES

Operating Leases

In June 2004, we entered into a lease agreement for laboratory and office facilities in Mountain View, California, or the Lease, and
in August 2006 we amended the Lease to include additional square footage within the same building. The Lease was to expire in June 2008. In March 2008, we entered into another amendment to the Lease, or the March 2008 Amendment, to extend the
term of the Lease until June 2012, and to include additional square footage and options to lease additional square footage. In September 2008, we amended and restated the Lease, providing for expanded square footage and certain renewal options.
Under the Lease, we pay operating costs, including property taxes, insurance and maintenance, in addition to monthly rent. Rent is subject to an annual increase for the duration of the Lease, which we recognize on a straight-line basis. The annual
lease payments for the space under the amended and restated Lease were effective on July 1, 2008.

Rent expense was
approximately $0.4 million, $0.3 million and $4.9 million for the three months ended March 31, 2010 and 2009, and for the cumulative period from July 3, 2003, (date of inception) to March 31, 2010, respectively.

As of March 31, 2010, future minimum lease payments are as follows (in thousands):



|                             |  |        |      
|---------------------------- |  | ------ | -----
|Year ending December 31,     |  | Amount
|2010 (remaining nine months) |  | $      | 986  
|2011                         |  |        | 1,357
|2012                         |  |        | 700  
|                             |  |        |      
|Total minimum lease payments |  | $      | 3,043
|                             |  |        |      

In accordance with the terms of the Lease, we are
obligated to maintain an irrevocable letter of credit from a bank as a security deposit. As collateral for the letter of credit, we are required to maintain a bank deposit account of $0.3 million, which is shown as a restricted investment on our
condensed consolidated balance sheets at March 31, 2010 and December 31, 2009, respectively.

Contingencies

We are subject to claims and assessments from time to time in the ordinary course of business. We do not believe that
any such matters, individually or in the aggregate, will have a material adverse effect on our financial condition or results of operation.

Indemnification

In the normal course of business, we enter into contracts and agreements that contain a variety of representations and warranties and
provide for indemnification. Our exposure under these agreements is unknown because it involves claims that may be made against us in the future, but have not yet been made. To date, we have not paid any claims or been required to defend any action
related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations.

In accordance with our certificate of incorporation and bylaws, we have indemnification obligations to our officers and directors for
certain events or occurrences, subject to certain limits, while they are serving at our request in their respective capacities. There have been no claims to date and we have a director and officer insurance policy that enables us to recover a
portion of any amounts paid for future potential claims.

NOTE 7. STOCKHOLDERS EQUITY

Warrants

In March 2010, warrants representing 24,668 shares were exercised, resulting in a net issuance of 12,295 shares. As of March 31,
2010, we had outstanding warrants remaining to purchase an aggregate of 26,903 shares of common stock, exercisable at a price of $7.43 per share. The remaining warrants were issued in connection with an earlier working capital loan agreement and
expire in September 2013.

Stock Option Activities

For the three months ended March 31, 2010, stock option activity under our 2007 Equity Award Plan, or the 2007 Plan, was as follows:

As of March 31, 2010, we had 2,102,747 shares of common stock available for grant under the
2007 Plan.

Stock-Based Compensation for Employees

The stock-based compensation expense recognized in the condensed consolidated statements of operations, including stock options granted,
shares purchased under the ESPP, and performance-based restricted stock units, was as follows (in thousands):

|                         |  |                              |   |  |          |

We used the following assumptions to estimate the fair value of shares purchased under
our ESPP for the three months ended March 31, 2010 and 2009, respectively:



|                         |  |                              |   |  |      |

|Risk-free interest rate  |  | 0.1                          | % |  | 0.3  | %
|Expected volatility      |  | 76                           | % |  | 99.4 | %
|Expected term (in years) |  | 0.5                          |   |  | 0.5  |  
|Expected dividend yield  |  |                             |   |  |     |  

Risk-Free Interest Rate:The risk-free interest rate assumption was based on U.S. Treasury instruments with a term that is
consistent with the expected term of our stock options or shares from the ESPP.

Expected Volatility:The expected
stock price volatility for our common stock was determined by examining the historical volatilities for industry peers and using an average of the historical volatilities of our industry peers as we did not have sufficient trading history for our
common stock. Industry peers consist of several public companies in the biopharmaceutical industry similar to us in size, stage of life-cycle and financial leverage.

Expected Term:The expected term for shares from the ESPP is determined based on the length of offering periods for the ESPP. The
expected term of stock options represents the weighted average period the stock options are expected to remain outstanding. It was calculated based on the historical experience that we have had with stock option grants as well as the expected term
of industry peers, as we did not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for the full term of our stock options. We will continue to
analyze the historical stock price volatility and expected term assumptions, as more historical data for our common stock becomes available.

Expected Dividend Yield:The expected dividend yield of 0% is based on our history and expectation of dividend payouts. We do not
anticipate paying any dividends in the near future. We have not paid any dividends, other than a cumulative dividend on our preferred stock paid in connection with our initial public offering, or IPO, in 2007, pursuant to the terms of our
certificate of incorporation.

Forfeitures:Stock-based compensation expense is determined based on when awards are
ultimately expected to vest, and it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
Forfeitures were estimated based on our historical experience.

As of March 31, 2010, there were unrecognized
compensation costs of approximately $8.4 million related to non-vested stock option awards granted after January 1, 2006 that will be recognized on a straight-line basis over the weighted average remaining period of 2.7 years.

Performance-Based Restricted Stock Units: On February 2, 2010, the Compensation Committee of the Board of Directors approved
awards of 98,000 performance-based restricted stock units from the 2007 Plan for certain of our employees. These awards will convert into shares of our common stock upon vesting at the end of the performance periods, if specific performance goals
set by the Compensation Committee are achieved. No performance shares will vest if the performance goals are not met. Each vested performance share will convert into one share of our common stock on the vesting date. The fair value of the
performance-based restricted stock units was determined using the stock price of our common stock on the date of the grant which was $16.19. A probability assessment that performance goals will be achieved is made quarterly. The compensation expense
is recognized over the vesting period, and is adjusted periodically for any changes to our probability assessment of the number of performance shares expected to vest as a result of our achievement of the performance goals. For the three months
ended March 31, 2010, we recorded compensation expense of $114,000. As of March 31, 2010, there were unrecognized compensation costs of approximately $1.2 million, net of estimated forfeitures, related to performance-based restricted stock
units.

Stock-Based Compensation for Non-Employees

Stock-based compensation expense related to stock options granted to non-employees is recognized as the stock options are earned.
Management believes that the fair value of the stock options is more reliably measurable than the fair value of the service received. The fair value of stock options granted to non-employees is calculated at each grant date and remeasured at each
reporting date. The stock-based compensation expense will fluctuate as the price of our common stock fluctuates. We recorded stock-based compensation expense for non-employees of $0, $18,000 and $0.9 million for the three months ended March 31,
2010 and 2009, and for the cumulative period from July 3, 2003 (date of inception) through March 31, 2010, respectively.

Equity Line of Credit

On November 11, 2009, we entered into a Common Stock Purchase Agreement, or the Purchase Agreement, with Azimuth Opportunity Ltd., or
Azimuth, which provides us with what is sometimes termed an equity line of credit arrangement. Upon the terms and subject to the conditions set forth in the Purchase Agreement, Azimuth committed to purchase up to $60 million worth of shares of our
common stock over the 24-month term of the Purchase Agreement; provided, however, in no event may we sell under the Purchase Agreement more than such number of shares of common stock which is equal to one share less than 20% of our outstanding
shares of common stock on the effective date of the Purchase Agreement. From time to time over the term of the Purchase Agreement, and at our sole discretion, we may present Azimuth with draw down notices requiring Azimuth to purchase a specified
dollar amount of shares of our common stock, based on the price per share over ten consecutive trading days or such other period mutually agreed upon by Azimuth and us, with each draw down subject to limitations based on the price of our common
stock and a maximum limit of 2.5% of our market capitalization at the time of such draw down, or such other limit as mutually agreed upon by Azimuth and us.

On January 11, 2010, we presented Azimuth with a draw down notice, which was subsequently amended. On January 28, 2010, we sold
an aggregate of 1,527,695 shares of our common stock to Azimuth under the Purchase Agreement at a price of approximately $13.70 per share, less a discount of approximately 4.5% per share, for a net price of approximately $13.09 per share. The
total purchase price for these shares was $20.0 million. We received net proceeds from the sale of these shares of approximately $19.7 million after deducting estimated offering expenses of approximately $335,000, including the placement agent fee
of $200,000 paid in connection with this offering. The offering price of these shares was established with reference to the volume weighted average prices of our common stock on The NASDAQ Global Market for the period beginning January 12, 2010
and ending January 26, 2010, net of a weighted average discount of approximately 4.5% per share.

Overview

Our goal is to use our proprietary inhalation technologies to enhance the therapeutic benefits and commercial attractiveness of proven
drugs while minimizing risk by capitalizing on their known safety, efficacy and commercialization history. We have proprietary product candidates in development that address large market opportunities. Our current focus is to advance our Phase 3
product candidate, LEVADEX orally inhaled migraine therapy, formerly known as MAP0004, a proprietary orally inhaled version of dihydroergotamine mesylate, or DHE, for the potential treatment of migraine.

LEVADEX

Migraine is a chronic and debilitating neurological disorder characterized by episodic attacks. Migraine attacks typically manifest
themselves as moderate to severe headache pain, with associated symptoms that often include nausea and vomiting, photophobia, phonophobia, and visual disturbances or aura. They usually involve pounding or throbbing pain on
one side of the head, although pain may occur on both sides. Migraines limit the normal functioning of patients, who often seek dark, quiet surroundings until the episode has passed. Most migraines last between four and 24 hours, but some last as
long as three days. According to published studies, the median frequency of attack is 1.5 times per month, although approximately 25% of migraine sufferers experience one or more attacks every week.

Migraine is a major public health problem that affects up to approximately 12% of the population in the United States and approximately
15% in Europe. According to the National Headache Foundation, approximately 30 million people in the United States suffer from migraine. In 2008, according to market data, approximately 29 million prescriptions were written for the
treatment of migraine in the United States. Approximately 12 million of those prescriptions were written for acute migraine specific drugs. The majority of acute migraine specific drug prescriptions written were in the triptan class. In 2009,
the triptan market in the United States totaled approximately $2.1 billion in revenues.

We have designed
LEVADEX to provide faster onset and longer-lasting migraine relief than triptans, the class of drugs most often prescribed for treating migraine. LEVADEX is an easy to use, at-home therapy in development that patients self-administer using our
proprietary hand-held Tempo® inhaler. DHE currently is available as an intravenous, or IV, therapy which has
been used in clinical settings for over 50 years for the safe and effective treatment of migraine, particularly forms of migraine that are severe or do not respond to triptans or other therapies. DHE also is available in an intranasal formulation.
We believe LEVADEX has the potential to be suitable as a first-line therapy for some migraine patients.

In May 2009, we
announced results of the efficacy portion of our first Phase 3 clinical trial of LEVADEX, or FREEDOM-301. The clinical trial met its four primary endpoints, pain relief and being nausea, phonophobia and photophobia free as reported two hours after
dosing. Additional endpoints showed that LEVADEX provided rapid and sustained pain relief for up to 48 hours after dosing.

##### Table of Contents

Patients taking LEVADEX therapy had statistically significant improvement at two hours
compared to patients on placebo for each of the primary endpoints:



| |  |  | Pain relief: 58.7 percent of patients who received LEVADEX compared with 34.5 percent for placebo (p<0.0001);
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | Phonophobia free: 52.9 percent of patients who received LEVADEX compared with 33.8 percent for placebo (p<0.0001);
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | Photophobia free: 46.6 percent of patients who received LEVADEX compared with 27.2 percent for placebo (p<0.0001); and
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | Nausea free: 67.1 percent of patients who received LEVADEX compared with 58.7 percent for placebo (p=0.02).
| | - |  | -----------------------------------------------------------------------------------------------------------

A total of 792 patients were included in the primary data analysis as specified in the protocol of the FREEDOM-301 study. The patient
population studied had more severe migraine pain than anticipated, with 46 percent reporting severe pain and 54 percent reporting moderate pain prior to administration of the study drug.

Results from additional pre-defined analyses include:



| |  |  | LEVADEX therapy achieved statistically significant onset of pain relief at 30 minutes after dosing (p=0.03);
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | While not statistically significant, 50% more of the patients receiving LEVADEX therapy than the patients receiving placebo reported pain relief at 10
minutes;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LEVADEX therapy achieved statistically significant sustained pain relief from two to 24 hours (p<0.0001), as well as two to 48 hours (p<0.0001,
when unadjusted for multiplicity);
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LEVADEX therapy achieved statistically significant pain freedom (pain symptom score = 0) as early as 30 minutes (p=0.002, when unadjusted for
multiplicity); and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LEVADEX therapy achieved sustained pain freedom from two to 24 hours, as well as two to 48 hours (p<0.0001 for both time points, when unadjusted for

LEVADEX was well tolerated, with the most common adverse event reported
being medication aftertaste at six percent, with two percent of patients receiving placebo also reporting medication aftertaste. The next most common adverse event was nausea at five percent, compared with two percent for placebo. Symptoms or
sensitivities typically associated with commonly used triptan migraine treatments, such as chest discomfort (one percent) or chest pain (zero percent), were rare and comparable to placebo. There were no mean decreases in lung function, as measured
by spirometry, between the active and placebo groups. There were no drug-related serious adverse events reported in the trial. These data were presented in September 2009 in a late-breaking session of the
14thCongress of the International Headache Society.

In September 2009, we announced that post-hoc analysis of data from this Phase 3 trial shows the potential of LEVADEX to be
effective in treating acute migraine as well as a broad spectrum of migraine, including migraine subpopulations that are often resistant to current therapies such as triptans, migraine with moderate and severe pain, migraine with nausea and vomiting
and migraine with and without aura.

In October 2009, we announced that we had completed a planned interim safety review of
the open-label, long-term safety extension of the FREEDOM 301 clinical trial. At the time of the interim review, more than 400 patients had completed at least six months of treatment and over 7,800 headaches had been treated in the safety extension.
No drug-related serious adverse events had been reported.

In January 2010, we announced that the U.S. Food and Drug
Administration, or the FDA, had informed us that a second pivotal efficacy study would not be required for the LEVADEX new drug application, or NDA, submission. We had previously anticipated initiating a second pivotal efficacy study in the first
quarter of 2010.

We are currently conducting an ongoing 12 month open-label safety extension of the FREEDOM-301 trial, a
pharmacokinetics, or PK, trial and a pharmacodynamics, or PD, trial. We anticipate that patients and subjects in these trials will complete treatment in 2010.

We hold worldwide commercialization rights for LEVADEX and our goal is to market LEVADEX in the United States through our own focused
sales force targeting neurologists and headache specialists. We may establish partnerships with pharmaceutical companies to market and sell to primary care physicians and specialists inside and outside of the United States.

Nebulized Budesonide

Unit Dose Budesonide, or UDB, is our proprietary nebulized version of budesonide intended to treat asthma in children
from 12 months to eight years of age. UDB is designed to be administered more quickly and to provide efficacy at lower doses than conventional nebulized budesonide. Conventional nebulized budesonide is an inhaled corticosteroid approved by the FDA
for treating asthma in children from 12 months up to eight years of age. Our UDB product candidate has been designed to achieve a particle size smaller than previously possible with budesonide. We believe this smaller particle size may allow for
faster delivery and efficacy at a lower dose, which together may offer improved safety, compliance and convenience.

In
December 2008 we entered into a worldwide collaboration with AstraZeneca AB to develop and commercialize UDB, or the AstraZeneca Agreement, which became effective on February 2, 2009. In February 2009, we announced top-line results from our
first Phase 3 trial of UDB, indicating that the trial did not meet its co-primary endpoints when compared to placebo. On July 8, 2009, we received a notice of termination of the AstraZeneca Agreement. Subsequently, we suspended development of
UDB. We are considering options for our pediatric asthma program moving forward, by leveraging our experience with budesonide and our expertise in particle technology, including the development of a next generation therapy with budesonide.

Other Pipeline Products

Our product portfolio also includes the two earlier stage product candidates listed below, both of which highlight the broad applicability
of our technologies to a diverse range of potential future products. While we do not plan to make further significant direct investment in these two product candidates, we plan to evaluate other potential product candidates which may utilize these
technologies, as well as potential partnership opportunities for further development and commercialization of these two product candidates.

Combination Particle Technology: We can apply our proprietary particle formulation technologies to deliver the optimal ratio of
multiple drugs in a reproducible and consistent manner. We combine two or more drugs together into a single micron sized particle at consistent and reproducible ratios, which may improve the delivery profile and stability of the resultant
combination therapy. We believe our proprietary technologies in this area have potential broad applicability for a number of small molecule combination product candidates in diverse indications via inhalation and other routes of delivery.



| |  |  | MAP0005: We demonstrated this combination particle capability with MAP0005, our proprietary single particle combination of an inhaled
corticosteroid and a long-acting beta-agonist, or LABA, for the potential treatment of asthma and chronic obstructive pulmonary disease, or COPD, using our proprietary Tempo inhaler. In April 2008, we announced positive results from a Phase 2a
clinical trial evaluating MAP0005 in adult asthmatics.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Stable Protein & Peptide Technology:
We have also demonstrated our ability to apply our proprietary technologies to formulate and stabilize biologically active proteins and peptides. We design and incorporate our protein formulations to avoid the need for excipients or other additives,
to be stored for months at room temperature and to deliver multiple doses of medicine accurately without needle injections.



| |  |  | MAP0001: We demonstrated this stable protein and peptide capability with MAP0001, our proprietary formulation of insulin for the
potential treatment of Type 1 and Type 2 diabetes via pulmonary delivery using our proprietary Tempo inhaler. This approach may overcome many of the issues currently associated with the invasive delivery of proteins by injection or infusion in
general, and with inhalable insulin therapies in particular.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We have not filed an investigational new drug
application, or IND, with the FDA for MAP0005 or MAP0001 because our clinical trials were not conducted in the United States.

A core part of our strategy is to reduce the risk of drug development by focusing on the development of proven drugs with established
safety and efficacy profiles. The compounds underlying our product candidates are well characterized and have been previously approved by the FDA for other sponsors and in other dosage forms and formulations. As a result, we may seek FDA marketing
approval of our product candidates under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, or FFDCA, which, if available to us, would allow any new drug application, or NDA, we file with the FDA to rely in part on data in the public
domain or the FDAs prior conclusions regarding the safety and efficacy of approved compounds. This may expedite the development program for our product candidates by potentially decreasing the overall scope of work we must do ourselves.

##### Table of Contents

We are a development stage company and have not generated any product revenues. Since our
inception, we have incurred losses and have an accumulated deficit of $198.9 million as of March 31, 2010. We have financed our operations through equity financing, debt financing, the issuance of convertible notes and collaboration payments.
We expect to continue to incur net losses for at least the next several years as we continue to develop our current product candidates, develop, acquire or in-license additional products or product candidates, expand clinical trials for our product
candidates in development, expand our research and development activities, seek regulatory approvals and engage in commercialization preparation activities in anticipation of potential FDA approval of our product candidates. We will need to raise
additional capital and expand our commercial organization to launch any products. Significant capital is required to launch a product, and many expenses are incurred before revenues are received. We are unable to predict the extent of any future
losses or when we will become profitable, if at all.

Critical Accounting Policies and Significant Judgments and
Estimates

There have been no significant changes in critical accounting policies during the three months ended
March 31, 2010, as compared to the critical accounting policies described in Item 7Managements Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting Policies and Significant
Judgments and Estimatesin our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

Financial Overview

Collaboration Revenue

We recognize revenues from collaborative research and development activities. Collaboration revenue, which is earned under agreements with
third parties for research and development activities, may include nonrefundable upfront payments, cost reimbursements and milestone payments.

Research and Development Expenses

Research and development costs include, but are not limited to, (i) expenses incurred under agreements with contract research
organizations and investigative sites, which conduct our clinical trials and a substantial portion of our pre-clinical studies; (ii) milestone payments paid to our collaborative partners who work on our processing and supply of clinical trial
material; (iii) the cost of manufacturing and supplying clinical trial materials; (iv) payments to contract service organizations, as well as consultants; (v) employee-related expenses, which include salaries and benefits;
(vi) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements and equipment and laboratory and other
supplies; and (vii) stock-based compensation expense. All research and development expenses are expensed as incurred.

Conducting a significant amount of research and development is central to our business model. Through March 31, 2010, we had
incurred approximately $189.5 million in research and development expenses since our inception in 2003. Product candidates in later-stage clinical development generally have higher development costs than those in earlier stages of development,
primarily due to the significantly increased size and duration of later-stage clinical trials. We plan to incur substantial research and development expenses for the foreseeable future in order to complete development of our most advanced product
candidate, LEVADEX, and to conduct earlier-stage research and development projects. Pursuant to the AstraZeneca Agreement, AstraZeneca reimbursed our development costs related to the UDB program beginning on the effective date of February 2,
2009. The agreement was terminated on July 8, 2009, and we suspended development of UDB in the third quarter of 2009.

The following table summarizes the percentages of our research and development expenses related to our two most advanced product
candidates and other earlier stage projects for the three months ended March 31, 2010 and 2009, respectively. The percentages summarized in the following table reflect costs directly attributable to each development candidate, which are tracked
on a project basis. A portion of our internal costs, including indirect costs relating to our product candidates, is not tracked on a project basis and has been allocated based on management estimates.

The process of conducting pre-clinical studies and clinical trials necessary to obtain FDA
approval is costly and time consuming. The probability of success for each product candidate and clinical trial may be affected by a variety of factors, including, among other things, the quality of the product candidates early clinical data,
investment in the program, competition, manufacturing capabilities and commercial viability. As a result of the uncertainties discussed above, uncertainty associated with clinical trial enrollment and risks inherent in the development process, we
are unable to determine the duration and completion costs of current or future clinical stages of our product candidates or when, or to what extent, we will generate revenues from the commercialization and sale of any of our product candidates.
Development timelines, probability of success and development costs vary widely. We are currently focused on developing our most advanced product candidate, LEVADEX. However, we will need substantial additional capital in the future in order to
complete the development and potential commercialization of LEVADEX and other product candidates.

Sales, General and
Administrative Expenses

Sales, general and administrative expenses consist primarily of compensation for executive,
finance, marketing, legal and administrative personnel, including stock-based compensation. Other sales, general and administrative expenses include facility costs not otherwise included in research and development expenses, legal and accounting
services, other professional services, the cost of market research activities and consulting fees. Through March 31, 2010, we had incurred approximately $51.1 million in sales, general and administrative expenses since our inception in 2003.

Results of Operations

Collaboration Revenue

Collaboration revenue includes amortization of the nonrefundable upfront payment and reimbursement of qualified development expenses from
AstraZeneca. Collaboration revenue for the quarter ended March 31, 2010, as compared to the same period in 2009, is as follows (in thousands):



|                      |  |                              |   |      |   |

|Collaboration revenue |  | $                            |  |      | $ | 7,484

Revenue for the first
quarter ended March 31, 2010 was $0 compared to $7.5 million for the same period in 2009. The revenue recognized in the first quarter of 2009 related to the amortization of a $40.0 million upfront payment received in February 2009 and to
reimbursements for UDB-related development expenses, pursuant to the AstraZeneca Agreement. The AstraZeneca Agreement was terminated in July 2009, and we suspended development of UDB in the third quarter of 2009.

Research and Development Expenses

Research and development expenses and percentage changes as compared to the prior year are as follows (dollar amounts are presented in

The decrease
in research and development expenses for the three months ended March 31, 2010 was driven primarily by a decrease of $4.9 million in clinical and other related expenses to support the UDB Phase 3 clinical program as a result of suspending the
development of our UDB product candidate in the third quarter of 2009, partially offset by an increase of $0.3 million in other general research and development expenses.

Liquidity and Capital Resources

Liquidity

We have incurred losses since our inception in July 2003 and as of March 31, 2010 we had an accumulated deficit of $198.9 million. We
will continue to incur losses until we generate sufficient revenue to offset our expenses, and we anticipate that we will continue to incur net losses for at least the next several years. We expect to incur increased research and development and
sales, general and administrative expenses related to our development and potential commercialization of LEVADEX and, as a result, we will need to generate significant net product sales, royalty and other revenues to achieve profitability.

We have financed our operations through equity financing, debt financing, the issuance of convertible notes and collaboration
payments, as follows:



| |  |  | Prior to our IPO in October 2007, we received net proceeds of $106.7 million from the issuance of convertible notes and convertible preferred stock;

| |  |  | In 2009, we received $54.2 million in an upfront payment and reimbursement of qualified development expenses pursuant to our now terminated
collaboration agreement with AstraZeneca.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of March 31, 2010, we had approximately
$69.2 million in cash and cash equivalents. Our cash and cash equivalents are held primarily in money market funds. Cash in excess of immediate requirements is invested in accordance with our investment policy with a view toward capital
preservation and liquidity.

Cash Flows

The following table shows a summary of our cash flows for the periods indicated (in thousands):

Net cash provided by
(used in) operating activities. We used $14.2 million of cash for operating activities for the three months ended March 31, 2010, compared to receiving cash of $24.2 million for the corresponding period in 2009. The usage of cash of
$14.2 million for the three months ended March 31, 2010 was due primarily to a net loss of $14.1 million and a decrease in accrued liabilities of $2.3 million as a result of paying down expenses related to the LEVADEX Phase 3 clinical program,
and UDB program, which was suspended in the third quarter of 2009, partially offset by stock-based compensation of $1.5 million. The cash provided by operating activities for the three months ended March 31, 2009 was due primarily to a $40.0
million nonrefundable upfront payment we received from AstraZeneca, partially offset by a net loss of $9.9 million for the three months ended March 31, 2009 and by an increase in accounts receivable of $4.7 million from AstraZeneca. The
AstraZeneca Agreement was terminated in July 2009.

Net cash provided by (used in) investing activities. We used
$1.0 million of cash for investing activities for the three months ended March 31, 2010, compared to receiving cash of $12.6 million for the corresponding period in 2009. The usage of cash of $1.0 million for the three months ended
March 31, 2010 was due primarily to purchase of property and equipment. The cash provided by investing activities for the three months ended March 31, 2009 was due primarily to sales and maturities of our short-term investments of $12.7
million. There were no purchases of investments for the three months ended March 31, 2009.

Net cash provided by (used
in) financing activities. We received $18.7 million of cash from financing activities for the three months ended March 31, 2010, compared to the usage of cash of $1.1 million for the corresponding period in 2009. The cash provided by
financing activities was due primarily to the net proceeds of approximately $19.7 million from the issuance of our common stock from the drawdown of the equity line of credit and proceeds from sales of shares through equity plans of $0.8 million,
partially offset by the repayment of debt of $1.8 million. The usage of cash of $1.1 million for the three months ended March 31, 2009 was due primarily to the repayments of $1.2 million of outstanding debt in the three months ended
March 31, 2009.

Equity Line of Credit

On November 11, 2009, we entered into a Common Stock Purchase Agreement, or the Purchase Agreement, with Azimuth, which provides us
with what is sometimes termed an equity line of credit arrangement. Upon the terms and subject to the conditions set forth in the Purchase Agreement, Azimuth committed to purchase up to $60 million worth of shares of our common stock over the
24-month term of the Purchase Agreement; provided, however, in no event may we sell under the Purchase Agreement more than such number of shares of common stock which is equal to one share less than 20% of our outstanding shares of common stock on
the effective date of the Purchase Agreement. From time to time over the term of the Purchase Agreement, and at our sole discretion, we may present Azimuth with draw down notices requiring Azimuth to purchase a specified dollar amount of shares of
our common stock, based on the price per share over ten consecutive trading days or such other period mutually agreed upon by Azimuth and us, with each draw down subject to limitations based on the price of our common stock and a maximum limit of
2.5% of our market capitalization at the time of such draw down, or such other limit as mutually agreed upon by Azimuth and us.

On January 11, 2010, we presented Azimuth with a draw down notice, which was subsequently amended. On January 28, 2010, we sold
an aggregate of 1,527,695 shares of our common stock to Azimuth under the Purchase Agreement at a price of approximately $13.70 per share, less a discount of approximately 4.5% per share, for a net price of approximately $13.09 per share. The
total purchase price for these shares was $20.0 million. We received net proceeds from the sale of these shares of approximately $19.7 million after deducting estimated offering expenses of approximately $335,000, including the placement agent fee
of $200,000 paid in connection with this offering. The offering price of these shares was established with reference to the volume weighted average prices of our common stock on The NASDAQ Global Market for the period beginning January 12, 2010
and ending January 26, 2010, net of a weighted average discount of approximately 4.5% per share.

Agreement
with Nektar

Under our June 2004 agreement, as amended, with Nektar Therapeutics UK Limited, or the Nektar
Agreement, we were granted a worldwide, exclusive license, with a right to sublicense, under Nektar patents and know-how, to develop and commercialize any formulation of a form of dihydroergotamine for administration by inhalation using a device. We
also agreed to pay royalties at specified rates based on net sales. As of March 31, 2010, we are required to make future nonrefundable milestone payments of up to $5.0 million related to products currently being developed under the Nektar
Agreement, when and if certain regulatory and commercial milestones are met. We paid $0, $0 and $2.6 million related to milestones for the three months ended March 31, 2010 and 2009 and for the cumulative period from July 3, 2003 (date of
inception) to March 31, 2010. Either party may terminate the Nektar Agreement upon a material, uncured default of the other party. We may terminate the Nektar Agreement, with or without cause, at any time upon six months prior written
notice.

Agreement with Elan

Under the April 2004 agreement, as amended, with Elan Pharma International Limited, or the Elan Agreement, Elan granted to us a
worldwide, exclusive, sub-licensable license under certain of Elans intellectual property rights related to our UDB product candidate. We also agreed to pay royalties at specified rates based on net sales. As of March 31, 2010, we may be
required to make future nonrefundable milestone payments of up to $16.5 million related to products developed under the Elan Agreement, when and if certain regulatory and commercial milestones under the Elan Agreement are met. We paid $0, $0 and
$4.0 million for the three months ended March 31, 2010 and 2009 and for the cumulative period from July 3, 2003 (date of inception) to March 31, 2010. Either party may terminate the Elan Agreement upon a material, uncured default of
the other party. We may terminate the agreement, with or without cause, at any time upon 90 days prior written notice. We also entered into a services agreement with Elan Drug Delivery International in February 2005, amended subsequently,
which describes the terms and conditions for clinical and commercial supply of product intermediate for our UDB product candidate.

Operating Capital and Capital Expenditure Requirements

Our future capital requirements will depend on many forward looking factors and are not limited to the following:



| |  |  | the initiation, progress, timing and completion of clinical trials for our product candidates and potential product candidates;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | the outcome, timing and cost of regulatory approvals and the regulatory approval process;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | delays that may be caused by changing regulatory requirements;
| | - |  | --------------------------------------------------------------



| |  |  | the number of product candidates that we pursue;
| | - |  | ------------------------------------------------



| |  |  | the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | the timing and terms of future in-licensing and out-licensing transactions;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the cost and timing of establishing sales, marketing, manufacturing and distribution capabilities;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the cost of procuring clinical and commercial supplies of our product candidates;
| | - |  | ---------------------------------------------------------------------------------

##### Table of Contents

| |  |  | the extent to which we acquire or invest in businesses, products or technologies; and
| | - |  | -------------------------------------------------------------------------------------



| |  |  | the possible costs of litigation.
| | - |  | ---------------------------------

We believe that our existing cash, cash equivalents and short-term investments, will be sufficient to fund our projected operating
requirements for at least 12 months. We will need substantial additional capital in the future in order to complete the development and commercialization of LEVADEX and to fund the development and commercialization of any future product candidates.
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. Such funding, if needed,
may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses.

If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our research or
development programs or our commercialization efforts. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve
restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not
be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Recent Accounting Pronouncements

In September 2009, the FASB ratified Revenue Arrangements with Multiple Deliverables issued as Accounting Standards Update, or ASU,
2009-13 in early October. ASU 2009-13 updates the existing multiple-element arrangements guidance currently included in ASC 605-25, Revenue Recognition  Multiple-Element Arrangements. The revised guidance provides for two significant
changes to the existing multiple-element arrangements guidance. The first relates to the determination of when the individual deliverables included in a multiple-element arrangement may be treated as separate units of accounting. This change is
significant as it will likely result in the requirement to separate more deliverables within an arrangement, ultimately leading to less revenue deferral. The second change modifies the manner in which the transaction consideration is allocated
across the separately identifiable deliverables. These changes are likely to result in earlier recognition of revenue for multiple-element arrangements than under previous guidance. ASU 2009-13 also significantly expands the disclosures required for
multiple-element revenue arrangements. The revised multiple-element arrangements guidance will be effective for the first annual reporting period beginning on or after June 15, 2010, and may be applied retrospectively for all periods presented
or prospectively to arrangements entered into or modified after the adoption date. Early adoption is permitted provided that the revised guidance is retroactively applied to the beginning of the year of adoption. If the guidance is adopted
prospectively, certain transitional disclosures are required for each reporting period in the initial year of adoption. As a result, it is effective for us in the first quarter of fiscal year 2011. We do not believe that the adoption of ASU 2009-13
will have a material impact on our condensed consolidated financial statements.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, including the use of structured finance,
special purpose entities or variable interest entities.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest
rates. We do not have any foreign currency or other derivative financial instruments.

We believe that there have been no
significant changes in our market risk exposures for the three months ended March 31, 2010.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures: As required by paragraph (b) of Rules 13a-15 and 15d-15
promulgated under the Securities Exchange Act of 1934, as amended, for the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation as of the end of the period covered by this report,
of the effectiveness of our disclosure controls and procedures as defined in Exchange Act Rule 13a-15(e) and 15d-15(e). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure
controls and procedures were effective as of the end of March 31, 2010, the period covered by this report.

PART II. OTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

We are
not a party to any material legal proceeding.



|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, 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.

Risks Relating to Our Financial Position and Need for Additional Capital

We have a history of net losses. Currently, we have no products approved for commercial sale, and to date we have not generated any product revenue.
As a result, we expect to continue to incur substantial and increasing net losses for the foreseeable future, and we may never achieve or maintain profitability.

We are not profitable and do not expect to be profitable in the foreseeable future. We have incurred significant net losses and negative
cash flow in each year since our inception, including net losses of approximately $40.1 million, $72.9 million and $9.0 million, for the years ended December 31, 2007, 2008 and 2009, respectively and $14.1 million for the quarter ended
March 31, 2010. As of March 31, 2010, we had a deficit accumulated during development stage of approximately $198.9 million. We have devoted most of our financial resources to research and development, including our pre-clinical
development activities and clinical trials. We have not completed development of, or commercialized any product candidate and have therefore not generated any product revenues. In that regard, we expect to have substantial expenses as we continue
with our Phase 3 clinical program for LEVADEX, our most advanced product candidate, and conduct other clinical trials. In addition, if we are required by the U.S. Food and Drug Administration, or the FDA, to perform studies in addition to those
we currently anticipate, our expenses will increase beyond expectations and the timing of any potential product approval may be delayed. We also expect an increase in our expenses associated with our manufacturing work and with preparing for
commercialization. In addition, we expect to continue to incur costs to support operations as a public company. As a result, we may continue to incur substantial net losses and negative cash flow for the foreseeable future. These losses and negative
cash flows have had, and will continue to have, an adverse effect on our stockholders equity and working capital.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict
the timing or amount of substantial expenses or when, or if, we will be able to achieve or maintain profitability. We have financed our operations primarily through the sale of equity securities, collaboration payments and debt financings. The size
of our future net losses will depend, in part, on the rate of growth of our expenses and the rate of growth, if any, of our revenues. Revenues from potential strategic partnerships are uncertain because we may not enter into any additional strategic
partnerships. On July 8, 2009, we received a notice of termination of our license agreement with AstraZeneca, or the AstraZeneca Agreement, related to our Unit Dose Budesonide, or UDB, product candidate. Under the AstraZeneca Agreement,
AstraZeneca had agreed to fund our remaining development activities for UDB and to reimburse us for costs we incur with respect to future development activities conducted for the U.S. registration of our UDB product candidate, subject to the terms
and conditions of the AstraZeneca Agreement. Following the termination of the AstraZeneca Agreement, we suspended development of UDB. If we are unable to develop and commercialize our other product candidates or if sales revenue from any product
candidate that receives marketing approval is insufficient, we will not achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability.

We have a limited operating history, and we expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis,
which may make it difficult to predict our future performance.

Our operations to date have been primarily limited to
organizing and staffing our company, developing our technology and undertaking pre-clinical studies and clinical trials of our product candidates. We have not yet obtained regulatory approvals for any of our product candidates. Consequently, any
predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history. Specifically, our financial condition and operating results have varied significantly in the past and will
continue to fluctuate from quarter-to-quarter and year-to-year in the future due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include the following factors,
among others:



| |  |  | our ability to obtain additional funding to develop our product candidates;
| | - |  | ---------------------------------------------------------------------------

candidates;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | market acceptance of our product candidates for which we obtain regulatory approval;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | our ability, and our partners ability, to establish an effective sales and marketing infrastructure;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | competition from existing products or new products that may emerge;
| | - |  | -------------------------------------------------------------------



| |  |  | the impact of competition, including generics, in the migraine market on our ability to commercialize LEVADEX;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | the ability of patients to obtain coverage of or sufficient reimbursement for our products;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | the ability to receive regulatory approval or commercialize our products outside of the United States;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | potential side effects of our future products that could delay or prevent commercialization or cause an approved drug to be taken off the market;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | regulatory difficulties relating to products that have already received regulatory approval;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | guidelines and recommendations of therapies published by various organizations;
| | - |  | -------------------------------------------------------------------------------



| |  |  | potential product liability claims;
| | - |  | -----------------------------------



| |  |  | potential liabilities associated with hazardous materials;
| | - |  | ----------------------------------------------------------



| |  |  | our ability to maintain adequate insurance policies;
| | - |  | ----------------------------------------------------



| |  |  | our dependency on third-party manufacturers to supply or manufacture our products;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | our ability to establish or maintain collaborations, licensing or other arrangements;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | our ability, our partners abilities, and third parties abilities to protect and assert intellectual property rights;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | costs related to and outcomes of potential intellectual property litigation;
| | - |  | ----------------------------------------------------------------------------



| |  |  | compliance with obligations under intellectual property licenses with third parties;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | our ability to adequately support future growth; and
| | - |  | ----------------------------------------------------



| |  |  | our ability to attract and retain key personnel to manage our business effectively.
| | - |  | -----------------------------------------------------------------------------------

Due to the various factors mentioned above, and others, the results of any prior quarterly or annual periods should not be relied upon as
indications of our future operating performance.

We will need substantial additional funding and if we are unable to raise capital
when needed, we would be forced to delay, reduce or eliminate our product development programs.

Developing
biopharmaceutical products, including conducting pre-clinical studies and clinical trials and establishing manufacturing capabilities, is expensive. We expect to have substantial research and development expenses in connection with our ongoing
activities, particularly as we focus on and proceed with our Phase 3 clinical program of LEVADEX, our most advanced product candidate. In addition, our expenses could increase beyond expectations if the FDA requires that we perform additional
studies to those that we currently anticipate, in which case the timing of any potential product approval may be delayed. We believe that our existing cash, cash equivalents and short-term investments will be sufficient to fund our projected
operating requirements for at least 12 months. We will need substantial additional capital in the future in order to complete the development and commercialization of LEVADEX and to fund the development and commercialization of future product
candidates. 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. Such
funding, if needed, may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses.

##### Table of Contents

If adequate funds are not available, we may be required to delay, reduce the scope of or
eliminate one or more of our research or development programs or our commercialization efforts. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt
financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or
to grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking
statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this Risk Factors section. We have based this estimate on assumptions that may
prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:



| |  |  | the scope, rate of progress and cost of our clinical trials and other research and development activities;
| | - |  | ----------------------------------------------------------------------------------------------------------



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



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



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



| |  |  | the terms and timing of any collaboration, licensing or other arrangements that we may establish;.
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | the cost and timing of completion of clinical and commercial-scale manufacturing activities; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the costs of establishing sales, marketing and distribution capabilities for any product candidates for which we may receive regulatory approval.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------

Risks Relating to the Development, Regulatory Approval and

Commercialization of Our Product Candidates

We are largely dependent on the success of one product candidate, and we cannot be certain that this product candidate will receive regulatory
approval.

We have invested a significant portion of our efforts and financial resources in the development of LEVADEX and
UDB. In February 2009, we announced top-line results from our first Phase 3 trial of UDB, indicating that the trial did not meet its co-primary endpoints in either dose evaluated when compared to placebo. In July 2009, we announced that we were
suspending development of UDB, after our partner AstraZeneca terminated our license agreement. We are now largely dependent on the success of one product candidate, LEVADEX, for which we are conducting a Phase 3 clinical development program. Our
ability to generate product revenue, which we do not expect will occur for at least the next several years, if ever, will depend heavily on the successful development, regulatory approval and commercialization of this product candidate. We may have
inadequate financial or other resources to advance LEVADEX through the clinical trial process, depending on the requirements of the FDA. In May 2009, we announced top-line results from the efficacy portion of our first Phase 3 trial of LEVADEX,
indicating that the trial met all its co-primary endpoints when LEVADEX was compared to placebo. A long-term safety extension of the study is ongoing. Although we had planned to initiate a second Phase 3 efficacy study in the first quarter of 2010,
we have been informed by the FDA that a second pivotal efficacy study is not required for submission of our NDA. We are conducting additional clinical trials, including a pharmacokinetics trial in approximately 24 adult smokers comparing them to
approximately 24 non-smokers and a pharmacodynamics trial evaluating pulmonary artery pressure in approximately 24 healthy volunteers using echocardiogram before submitting an application to the FDA for regulatory approval. We expect treatment in
our remaining LEVADEX clinical trials to be completed in 2010. Our clinical development program for LEVADEX may not lead to regulatory approval from the FDA and similar foreign regulatory agencies if we fail to demonstrate that the product candidate
is safe and effective in our planned clinical trials, and we may therefore fail to commercialize LEVADEX. Any failure to obtain regulatory approval of LEVADEX would have a material and adverse impact on our business.

##### Table of Contents

With the suspension of development for our UDB product candidate, LEVADEX is our only
current product candidate in late stage development. Our drug development efforts may not produce any other proprietary product candidates. We cannot be certain that we will be able to acquire or in-license other product candidates or develop a next
generation budesonide therapy for the treatment of asthma in children, should we pursue these activities. Our failure to develop product candidates will limit our ability to generate additional revenue.

We currently have no approved 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 United States and other countries, with regulations
differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a new drug application, or an NDA, from the FDA for each product candidate. We have not submitted an NDA or
received marketing approval for any of our product candidates. Obtaining approval of an NDA is a lengthy, expensive and uncertain process. Markets outside of the United States also have requirements for approval of drug candidates which we must
comply with prior to marketing.

We may enter into collaborations with third parties to develop and commercialize our product candidates,
including LEVADEX. These collaborations may place the development of our product candidates outside our control, may require us to relinquish important rights or may otherwise be on terms unfavorable to us.

We may enter into collaborations with third parties to develop and commercialize our product candidates, including LEVADEX. Our dependence
on future partners for development and commercialization of our product candidates will subject us to a number of risks, including:



| |  |  | we may not be able to control the amount and timing of resources that our partners may devote to the development or commercialization of product
candidates or to their marketing and distribution;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

Delays in the commencement, enrollment and completion of clinical testing could
result in increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.

Delays in the commencement, enrollment and completion of clinical testing could significantly affect our product development costs. We do
not know whether planned clinical trials for LEVADEX will begin on time or be completed on schedule, if at all. 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 be required to withdraw from our clinical trial as a result of changing standards of care or may become ineligible to participate in
clinical studies. The commencement, enrollment 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 contract 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;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;

| |  |  | unforeseen safety issues or any determination that a trial presents unacceptable health risks; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | lack of adequate funding to continue the clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional trials

If we
are required to conduct additional clinical trials or other testing of our LEVADEX product candidate beyond those that we currently contemplate, we may be delayed in obtaining, or may not be able to obtain, marketing approval for this product
candidate. We are conducting a Phase 3 clinical program for LEVADEX. We are completing our long-term safety extension and are currently conducting a pharmacokinetics trial and a pharmacodynamics trial in support of our new drug application for
LEVADEX. We may not be able to obtain approval for indications that are as broad as intended or we may obtain approval for indications different than those indications for which we seek approval. Furthermore we may not be able to obtain approval for
any of our other product candidates.

Additionally, changes in regulatory requirements and guidance may occur and we may need
to amend clinical trial protocols to reflect these changes with appropriate regulatory authorities. Amendments may require us to resubmit our clinical trial protocols to IRBs for re-examination, 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 or similar indications may have been introduced to the market and established a competitive advantage.

Because the results of prior clinical trials are not necessarily predictive of future results, LEVADEX or any other product candidate advanced into
clinical trials may not have favorable results in subsequent clinical trials or receive regulatory approval.

Success in
pre-clinical studies and clinical trials does not ensure that subsequent 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, have suffered significant setbacks in Phase 3 clinical trials, even after seeing promising results in prior clinical trials.

In May 2009, we announced top-line results from the efficacy portion of our Phase 3 trial of LEVADEX, indicating that the trial met all
four of its co-primary endpoints when LEVADEX was compared to placebo. A long-term safety extension of this Phase 3 trial is ongoing. In order to obtain regulatory approval for LEVADEX, we need to complete this long-term safety extension trial and
other clinical trials, including a pharmacokinetics trial and a pharmacodynamics trial. The data collected from our clinical trials may not be adequate to support regulatory approval of LEVADEX or any of our other product candidates. Even if we
obtain regulatory approval of a product candidate, the FDA may require continuing evaluation and study of our product through clinical trials as a condition of any approval. Despite the results reported in prior clinical trials for our product
candidates, we do not know whether subsequent clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market our product candidates. For example, after receiving positive data from a previous
Phase 2 trial, in February 2009 we announced top-line results from our Phase 3 trial of UDB, indicating that the trial did not meet its co-primary endpoints in either dose evaluated when compared to placebo.

If clinical trials of our LEVADEX product candidate or future product candidates do not produce results
necessary to support regulatory approval in the United States or elsewhere or show undesirable side effects, we will be unable to commercialize these products.

To receive regulatory approval for the commercial sale of LEVADEX or any other product candidates, we must conduct 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. In such cases, we may decide, or regulators may require us, to conduct additional clinical and/or non-clinical testing, or we may decide not to pursue further development of a product candidate, such as the case of
our UDB product candidate, where top-line results of our Phase 3 clinical trial indicated that the trial failed to meet the primary endpoints. Subsequently we suspended development of UDB. In addition, the results of our clinical trials may show
that our product candidates may cause undesirable side effects, which could interrupt, delay or halt clinical trials, resulting in our inability to obtain regulatory approval by the FDA and other regulatory authorities.

In light of widely publicized events concerning the safety risk of certain drug products, regulatory authorities, members of Congress,
the Government Accounting Office, medical professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of drug products, revisions to drug labeling that further limit use
of the drug products and establishment of risk management programs that may, for instance, restrict distribution of drug products. The increased attention to drug safety issues may result in a more cautious approach by the FDA to clinical trials and
regulatory approval. Data from clinical trials may receive greater scrutiny with respect to safety, which may make the FDA or other regulatory authorities more likely to terminate clinical trials before completion, or require longer or additional
clinical trials that may result in substantial additional expense and a delay or failure in obtaining approval or approval for a more limited indication than originally sought.

Our failure to adequately demonstrate the efficacy and safety of LEVADEX or any other product candidates would prevent regulatory
approval and, ultimately, the commercialization of that product candidate.

All of our product candidates in development require regulatory
review and approval prior to commercialization. Any delay in the regulatory review or approval of any of our product candidates in development will harm our business.

All of our product candidates in development require regulatory review and approval prior to commercialization. Any delays in the
regulatory review or approval of our product candidates in development would delay market launch, increase our cash requirements and result in additional operating losses.

The process of obtaining FDA and other required regulatory approvals, including foreign approvals, often takes many years and can vary
substantially based upon the type, complexity and novelty of the products involved. Furthermore, this approval process is extremely complex, expensive and uncertain. We or our partners may not be able to maintain our proposed schedules for the
submission of any NDA in the United States or any marketing approval application or other foreign applications for any of our products. If we or our partners submit any NDA, including any amended NDA or supplemental NDA, to the FDA seeking marketing
approval for any of our product candidates, the FDA must decide whether to either accept or reject the submission for filing. We cannot be certain that any of these submissions will be accepted for filing and reviewed by the FDA, or that our
marketing approval application submissions to any other regulatory authorities will be accepted for filing and review by those authorities. We cannot be certain that we or our partners will be able to respond to any regulatory requests during the
review period in a timely manner without delaying potential regulatory action. We also cannot be certain that any of our product candidates will receive favorable recommendation from any FDA advisory committee or foreign regulatory bodies or be
approved for marketing by the FDA or foreign regulatory authorities. In addition, delays in approvals or rejections of marketing applications may be based upon many factors, including regulatory requests for additional analyses, reports, data and/or
studies, regulatory questions regarding data and results, changes in regulatory policy during the period of product development and/or the emergence of new information regarding our products or other products.

Data obtained from pre-clinical studies and clinical trials are subject to different interpretations, which could delay, limit or prevent
regulatory review or approval of any of our products. In addition, as a routine part of the evaluation of any potential drug, clinical studies are generally conducted to assess the potential for drug - drug interactions that could impact potential
product safety. At this point in time, we have not been requested to perform drug - drug interaction studies, but any such request may delay any potential product approval and will increase our expenses associated with our clinical programs.
Furthermore, regulatory attitudes towards the data and results required to demonstrate safety and efficacy can change over time and can be affected by many factors, such as the emergence of new information, including on other products, changing
policies and agency funding, staffing and leadership. We cannot be sure whether future changes to the regulatory environment will be favorable or unfavorable to our business prospects.

In addition, the environment in which our regulatory submissions may be reviewed changes
over time. For example, average review times at the FDA for marketing approval applications have fluctuated over the last ten years, and we cannot predict the review time for any of our submissions with any regulatory authorities. In addition,
review times can be affected by a variety of factors, including budget and funding levels and statutory, regulatory and policy changes.

We
may not be able to rely on Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, which could result in a longer development program and more costly trials than we anticipate.

We may not be able to seek FDA marketing approval of our product candidates under Section 505(b)(2) of the FFDCA.
Section 505(b)(2), if applicable to us, would allow an NDA we file with the FDA to rely in part on data in the public domain or the FDAs prior conclusions regarding the safety and effectiveness of approved compounds, which could expedite
the development program for our product candidates by potentially decreasing the overall scope of work we must do ourselves. If we are unable to rely on Section 505(b)(2), the development program for our product candidates would be longer than
we expect, and we would also have to conduct more costly trials than we anticipate.

If any of our product candidates for which we or our
partners 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 or our partners obtain marketing approval from the FDA or other regulatory
authorities will depend upon the acceptance of these products among physicians, the medical community, patients, 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:



| |  |  | a products FDA-approved labeling as well as limitations or warnings contained in the labeling;
| | - |  | -----------------------------------------------------------------------------------------------



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



| |  |  | limitations inherent in the approved indication for any of our product candidates compared to more commonly understood or addressed medical conditions;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | lower demonstrated efficacy and a less favorable safety or tolerability profile compared to other products;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | device-related difficulties associated with our Tempo inhaler;
| | - |  | --------------------------------------------------------------



| |  |  | prevalence and severity of adverse effects;
| | - |  | -------------------------------------------



| |  |  | ineffective marketing and distribution efforts;
| | - |  | -----------------------------------------------



| |  |  | lack of availability of reimbursement from managed care plans and other third-party payors;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | lack of cost-effectiveness;
| | - |  | ---------------------------



| |  |  | timing of market introduction and perceived effectiveness of competitive products;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | availability of alternative therapies, including generics, at similar or lower costs;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | patients potential preferences to take oral medications over inhaled medications; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | potential product liability claims.
| | - |  | -----------------------------------

Our and our partners ability to effectively promote and sell our product candidates in the marketplace will also depend on pricing
and cost effectiveness, including our and our partners ability to manufacture a product at a competitive price. We will also need to demonstrate acceptable evidence of safety and efficacy and may need to demonstrate relative convenience and
ease of administration. Inhaled versions of certain previously approved drugs have suffered commercial failure, including recently inhaled insulin. 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 and our partners 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. If our approved drugs fail to achieve market acceptance, we will not be able to generate significant revenue, if any.

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

We plan to market or co-promote our products where appropriate and build our own focused sales force in the United States. We currently do
not have significant internal sales, distribution and marketing capabilities. For example, in order to commercialize LEVADEX, we intend to develop a focused sales force and marketing capabilities in the United States directed at high prescribers
including specialists such as neurologists and headache specialists. The development of a 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 of any product launch. Many of these costs will be incurred in advance of notice to us that any of our product candidates has been approved. In addition, we may not be able to hire a
focused sales force in the United States that is sufficient in size or has adequate expertise in the medical markets that we intend to target, including neurology. If we are unable to establish our focused sales force and marketing capability for
our most advanced product candidate, we may not be able to generate any product revenue, may generate increased expenses and may never become profitable.

We expect intense competition with respect to our existing and future product candidates.

The pharmaceutical industry is highly competitive, with a number of established, large pharmaceutical companies, as well as many smaller
companies. Many of these companies have greater financial resources, marketing capabilities and experience in obtaining regulatory approvals for product candidates. There are many pharmaceutical companies, biotechnology companies, public and private
universities, government agencies and research organizations actively engaged in research and development of products which may target the same indications as our product candidates. We expect any future products we develop to compete on the basis
of, among other things, product efficacy and safety, time to market, price, extent of adverse side effects and convenience of treatment procedures. One or more of our competitors may develop products based upon the principles underlying our
proprietary technologies earlier than us, obtain approvals for such products from the FDA more rapidly than us or develop alternative products or therapies that are safer, more effective and/or more cost effective than any products developed by us.

Competitors may seek to develop alternative formulations of our product candidates that address our targeted indications. The
commercial opportunity for our product candidates could be significantly harmed if competitors are able to develop alternative formulations outside the scope of our products. Compared to us, many of our potential competitors have substantially
greater:



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



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



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



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



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



| |  |  | manufacturing and distribution experience; and
| | - |  | ----------------------------------------------



| |  |  | sales and marketing resources and 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.

The migraine market is extremely competitive which may
negatively impact our ability to commercialize LEVADEX.

If approved for the treatment of acute migraine, we anticipate
that LEVADEX would compete against other marketed migraine therapies and may compete with products currently under development by both large and small companies. The majority of marketed prescription products for treatment of migraine are in the
triptan class. The largest selling triptan is sumatriptan with 2009 sales of approximately $800 million in the United States including approximately $600 million from generics and $200 million from branded Imitrex from GlaxoSmithKline. There are at
least six other branded triptan therapies being sold by pharmaceutical companies. Alternative formulations of triptans are available that may have faster onset of action than solid oral dosage forms. In April 2008, GlaxoSmithKlines Treximet, a
combination oral formulation of sumatriptan and naproxen sodium, was approved by the FDA for the acute treatment of migraine. In July 2009, Zogenix, Incs Sumavel DosePro needle-free sumatriptan was approved by the FDA for the treatment of
acute migraine and cluster headache. Alternative formulations of dihydroergotamine, or DHE, include Migranal, which is nasally delivered, and which may become generically available prior to any commercial introduction of LEVADEX. In addition to the
marketed migraine therapeutics, there are product candidates under development by large pharmaceutical companies, such as Merck & Co., Inc., and other smaller companies, that could potentially be used to treat acute migraine and compete
with LEVADEX. In addition, Allergan, Inc. is developing Botox botulinum toxin for the potential treatment of chronic migraine.

##### Table of Contents

We also may face competition from generic sumatriptan, the active ingredient in Imitrex. The
FDA has approved generic versions of sumatriptan. Although we believe generic sumatriptan could not be substituted for LEVADEX, a generic version of sumatriptan may be more quickly adopted by health insurers and patients than LEVADEX. Financial
pressure to use generic products and uncertainty of reimbursement for single source alternatives, such as LEVADEX, may encourage the use of a generic product over LEVADEX.

If our patients are unable to obtain coverage of or sufficient reimbursement for our products, it is unlikely that our products will be widely used.

Successful sales of our products depend on the availability of adequate coverage and reimbursement from third-party
payors. Healthcare providers that purchase medicine or medical products for treatment of their patients generally rely on third-party payors to reimburse all or part of the costs and fees associated with the products. Adequate coverage and
reimbursement from governmental payors, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. Patients are unlikely to use our products if they do not receive reimbursement adequate to cover the cost of our
products.

In addition, the market for our future products will depend significantly on access to third-party payors
drug formularies, or lists of medications for which third-party payors provide coverage and reimbursement. Industry competition to be included in such formularies results in downward pricing pressures on pharmaceutical companies. Third-party payors
may refuse to include a particular branded drug in their formularies when a generic equivalent is available.

All third-party
payors, whether governmental or commercial, whether inside the United States or outside, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the United States, no uniform policy of coverage and
reimbursement for medical technology exists among all these payors. Therefore, coverage of and reimbursement for medical products can differ significantly from payor to payor.

Further, we believe that future coverage and reimbursement may be subject to increased restrictions both in the United States and in
international markets, pursuant to currently proposed healthcare reforms or otherwise. Third-party coverage and reimbursement for our products may not be available or adequate in either the United States or international markets, limiting our
ability to sell our products on a profitable basis.

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

In order to market and
commercialize any products outside of the United States, we and our partners must establish and comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and
can involve additional pre-clinical studies and clinical trials and additional administrative review periods. For example, European regulatory authorities generally require clinical testing comparing the efficacy of the new drug to an existing drug
prior to granting approval. 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 United States, 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 other countries. 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 United States. 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.

Our product candidates may have undesirable side effects and cause our approved drugs to be taken off the market.

If our most advanced product candidate, LEVADEX, or any other product candidate, receives marketing approval and we or others later
identify undesirable side effects caused by such products:



| |  |  | regulatory authorities may require the addition of labeling statements, specific warnings, contraindications or field alerts to physicians and
pharmacies;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | regulatory authorities may withdraw their approval of the product and require us to take our approved drug off the market;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



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



| |  |  | we may have limitations on how we promote our drugs;
| | - |  | ----------------------------------------------------



| |  |  | sales of products may decrease significantly;
| | - |  | ---------------------------------------------



| |  |  | we may be subject to litigation or product liability claims; 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.

Even if our product candidates receive regulatory approval, we and our partners 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. Given the number of recent high profile adverse safety events with certain drug products, the FDA may require, as a condition of approval,
costly risk management programs which may include safety surveillance, restricted distribution and use, patient education, enhanced labeling, special packaging or labeling, expedited reporting of certain adverse events, pre-approval of promotional
materials and restrictions on direct-to-consumer advertising. In addition, the FDA could condition any approval of LEVADEX on our implementation of a post-approval risk management plan. Furthermore, heightened Congressional scrutiny on the adequacy
of the FDAs drug approval process and the agencys efforts to assure the safety of marketed drugs has resulted in the proposal of new legislation addressing drug safety issues. If enacted, any new legislation could result in delays or
increased costs during the period of product development, clinical trials and regulatory review and approval, as well as increased costs to assure compliance with any new post-approval regulatory requirements. Any of these restrictions or
requirements could force us to conduct costly studies or increase the time for us to become profitable. For example, any labeling approved for LEVADEX or any other product candidates may include a restriction on the term of its use, or it may
not include one or more of our intended indications. The FDA historically has required that labeling for products containing DHE include a contraindication for use in women who are, or who may become, pregnant. Although we believe that this
contraindication is not applicable to our formulation of DHE, the FDA may disagree and require the LEVADEX labeling to carry this contraindication.

Our product candidates will also be subject to ongoing FDA requirements for the current Good Manufacturing Practices (cGMP) 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, or fail to be made in compliance with applicable
regulatory requirements such as cGMP, a regulatory agency may:



| |  |  | issue warning 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.
| | - |  | -----------------------------------------------------

We or our potential partners will need to obtain FDA approval of the proposed product names for our product candidates and any failure or delay
associated with such approval may adversely impact our business.

Any name we or our potential partners intend to use for
our product candidates will require approval from the FDA regardless of whether we or our partners 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 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 our product names, we may be
required to adopt an alternative name for our product candidates. If we or our partners adopt an alternative name, we or our partners would lose the benefit of our existing trademark applications 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 or our partners 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.

Guidelines and recommendations published by various organizations may affect the use of our products.

Government agencies issue regulations and guidelines directly applicable to us and to our products. In addition,
professional societies, practice management groups, private health/science foundations and organizations involved in various diseases from time to time publish guidelines or recommendations to the medical and patient communities. These various sorts
of recommendations may relate to such matters as product usage, dosage, route of administration and use of related or competing therapies. Changes to this recommendation or other guidelines advocating alternative therapies could result in decreased
use of our products, which may adversely affect our results of operations.

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, if at all,
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;
| | - |  | -------------------------------------------------------------



| |  |  | costs of related litigation;

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



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

We have obtained limited product liability insurance coverage for our clinical trials domestically and in selected foreign countries
where we conduct 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.

Our operations involve hazardous materials, which could subject us to significant liabilities.

Our research and development processes involve the controlled use of hazardous materials, including chemicals. Our
operations produce hazardous waste products. We cannot eliminate the risk of accidental contamination or discharge or injury from these materials. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and
disposal of these materials. We could be subject to civil damages in the event of an improper or unauthorized release of, or exposure of individuals, including employees, to, hazardous materials. In addition, claimants may sue us for injury or
contamination that results from our use of these materials and our liability may exceed our total assets. We maintain limited insurance for the use of hazardous materials which may not be adequate to cover any claims. Compliance with environmental
and other laws and regulations may be expensive and current or future regulations may impair our research, development or production efforts.

Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. For example, we do not carry
earthquake insurance. In the event of a major earthquake in our region, our business could suffer significant and uninsured damage and loss. Some of the policies we currently maintain include general liability, property, auto, workers
compensation, products liability and directors and officers insurance policies. Our insurance is expensive and we do not know if we will be able to maintain existing insurance with adequate levels of coverage. Any significant uninsured
liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

Risks Related to Our Dependence on Third Parties

We have no experience manufacturing large clinical-scale or commercial-scale pharmaceutical products and we do not own or operate a manufacturing
facility. As a result, we are dependent on numerous third parties for the manufacture of our product candidates and our supply chain, and if we experience problems with any of these suppliers the manufacturing of our products could be delayed.

We do not own or operate manufacturing facilities for clinical or commercial manufacture of our product candidates, which
includes drug substance and drug packaging, including the components of the Tempo inhaler, the device used to administer certain of our drug candidates, including LEVADEX. We have limited personnel with experience in drug manufacturing and we lack
the capabilities to manufacture any of our product candidates on a clinical or commercial scale. We currently outsource all manufacturing and packaging of our pre-clinical and clinical product candidates to third parties. In addition, we do not
currently have all necessary agreements with third-party manufacturers for the long-term commercial supply of our product candidates. We may be unable to enter agreements for commercial supply with all third-party manufacturers, or may be unable to
do so on acceptable terms. Even if we enter into these agreements or, for those agreements that we have already entered into, the various manufacturers of each product candidate will likely be single source suppliers to us for a significant period
of time. We may not be able to establish additional sources of supply for our products prior to commercialization. Such suppliers are subject to regulatory requirements covering manufacturing, testing, quality control and record keeping relating to
our product candidates, and are subject to ongoing inspections by the regulatory agencies. Failure by any of our suppliers to comply with applicable regulations may result in long delays and interruptions to our manufacturing capacity while we seek
to secure another supplier that meets all regulatory requirements.

Reliance on third-party manufacturers entails risks to
which we would not be subject if we manufactured the product candidates ourselves, including:



| |  |  | reliance on the third parties for regulatory compliance, quality assurance and hazardous materials handling;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | the possible breach of the manufacturing agreements by the third parties because of factors beyond our control; and
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility of termination or nonrenewal of the agreements by the third parties because of our breach of the manufacturing agreement or based on
their own business priorities.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any of these factors could cause the delay or suspension of initiation or
completion of clinical trials, regulatory submissions, required approvals or commercialization of our products, cause us to incur higher costs and could prevent us from commercializing our product candidates successfully. Furthermore, if our
contract manufacturers fail to deliver the required commercial quantities of finished product on a timely basis and at commercially reasonable prices and we are unable to find one or more replacement manufacturers capable of production at a
substantially equivalent cost, in substantially equivalent volumes and quality and on a timely basis, we would likely be unable to meet demand for our products and we would lose potential revenue. It may take a significant period of time to
establish an alternative source of supply for our product candidates and to have any such new source approved by the FDA.

If we are unable
to establish marketing, sales and distribution collaborations with third parties, we may not be able to commercialize LEVADEX successfully.

We plan to establish marketing, sales and distribution collaborations with third parties where appropriate. For example, if we choose to
expand the marketing and sales of LEVADEX to primary care physicians beyond high prescribers, including specialists such as neurologists and headache specialists, we may establish partnerships with other companies to maximize the potential of the
commercialization opportunity. Outside the United States, we may establish commercial partnerships for LEVADEX in order to effectively reach target markets in order to maximize its commercial opportunities. We also expect to face competition in our
efforts to identify appropriate collaborators or partners to help commercialize LEVADEX in our target commercial areas. If we are unable to establish adequate marketing, sales and distribution collaborations to target primary care physicians,
specialists and other large groups of prescribing physicians within and outside the United States, then we may not be able to achieve the full commercial opportunity for LEVADEX.

We may not be successful in maintaining or establishing development collaborations, which could adversely
affect our ability to develop certain of our product candidates.

On July 8, 2009, we received a notice of termination
of our AstraZeneca Agreement related to our UDB product candidate. Our AstraZeneca Agreement provided that AstraZeneca could terminate the agreement in the event that the primary endpoints of our Phase 3 clinical trial of UDB were not met. Following
the termination of the AstraZeneca Agreement, we suspended development of UDB. In addition, our earlier stage product portfolio includes MAP0005 and MAP0001. We have no current intention to further develop either of these earlier stage product
candidates independently. Developing pharmaceutical products, conducting clinical trials, establishing manufacturing capabilities and marketing approved products is expensive. Consequently, we may establish partnerships for further development and
commercialization of these two product candidates. We expect to face competition in seeking appropriate partners. Moreover, collaboration arrangements are complex and time consuming to negotiate, document and implement and they may require
substantial resources to maintain. We may not be successful in our efforts to establish and implement collaborations or other alternative arrangements, if any. The terms of any collaboration or other arrangement that we establish may not be
favorable to us. In addition, any collaboration that we enter into may not be successful. If we seek partners to help develop MAP0005 and MAP0001, but are unable to reach agreements with suitable partners, we may fail to commercialize the affected
product or program.

Risks Relating to Our Intellectual Property

It is difficult and costly to protect our proprietary rights, and 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 of our product
candidates and the methods used to manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing our products is
dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.

We license certain intellectual property from third parties that covers our product candidates. We rely on certain of these third parties
to file, prosecute and maintain patent applications and otherwise protect the intellectual property to which we have a license, and we have not had and do not have primary control over these activities for certain of these patents or patent
applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and
other intellectual property rights. Our enforcement of certain of these licensed patents or defense of any claims asserting the invalidity of these patents would also be subject to the cooperation of the third parties.

The patent positions of pharmaceutical and biopharmaceutical 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 biopharmaceutical patents has emerged to date in the United States. The biopharmaceutical patent situation outside
the United States is even more uncertain. Changes in either the patent laws or in interpretations of patent laws in the United States 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 the patents we own or to which we have a license from a third-party. Further, if any of our patents are deemed invalid and unforceable, it could impact our ability to commercialize or license our
technology.

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:



| |  |  | others may be able to make compositions or formulations that are similar to our product candidates but that are not covered by the claims of our
patents;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we might not have been the first to make the inventions covered by our issued patents or pending patent applications;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | we might not have been the first to file patent applications for these inventions;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | others may independently develop similar or alternative technologies or duplicate any of our technologies;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | it is possible that our pending patent applications will not result in issued patents;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | our issued patents may not provide us with any competitive advantages, or may be held invalid or unenforceable as a result of legal challenges by third
parties;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may not develop additional proprietary technologies that are patentable; or
| | - |  | ------------------------------------------------------------------------------



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

We also may rely on trade secrets to protect our technology, especially where we do not
believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our 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 any of our trade secrets is expensive and time consuming, and the outcome is unpredictable.
In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be
unable to protect our rights to, or use, our technology.

If we or our partners choose to go to court to stop someone else
from using the inventions claimed in our patents, that individual or company has the right to ask the court to rule that these patents are invalid and/or should not be enforced against that third party. These lawsuits are expensive and would consume
time and other resources even if we were successful in stopping the infringement of these patents. In addition, there is a risk that the court will decide that these patents are not valid and that we do not have the right to stop the other party
from using the inventions. There is also the risk that, even if the validity of these patents is upheld, the court will refuse to stop the other party on the ground that such other partys activities do not infringe our rights to these patents.
In addition, the U.S. Supreme Court has recently invalidated some tests used by the U.S. Patent and Trademark Office in granting patents over the past 20 years. As a consequence, several issued patents may be found to contain invalid claims
according to the newly revised standards. Some of our own or in-licensed patents may be subject to challenge and subsequent invalidation in a re-examination proceeding before the U.S. Patent and Trademark Office or during litigation under the
revised criteria which make it more difficult to obtain patents.

Furthermore, a third party may claim that we or our
manufacturing or commercialization partners are using inventions covered by the third partys patent rights and may go to court to stop us from engaging in our normal operations and activities, including making or selling our product
candidates. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and technical personnel. There is a risk that a court would decide that we or our commercialization partners are infringing the
third partys patents and would order us or our partners to stop the activities covered by the patents. In addition, there is a risk that a court will order us or our partners to pay the other party damages for having violated the other
partys patents. We have agreed to indemnify certain of our commercial partners against certain patent infringement claims brought by third parties. The biotechnology industry has produced a proliferation of patents, and it is not always clear
to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent
infringement, we would need to demonstrate that our products or methods of use either do not infringe the patent claims of the relevant patent and/or that the patent claims are invalid, and we may not be able to do this. Proving invalidity, in
particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.

Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent
applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that
others have not filed patent applications for technology covered by our issued patents or our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications
covering technology similar to ours. Any such patent application may have priority over our patent applications or patents, which could further require us to obtain rights to issued patents by others covering such technologies. If another party has
filed a U.S. patent application on inventions similar to ours, we may have to participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine priority of invention in the United States. The costs of
these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of
our U.S. patent position with respect to such inventions.

Some of our competitors may be able to sustain the costs of
complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our
ability to raise the funds necessary to continue our operations.

If we fail to comply with our obligations in our intellectual property licenses with third parties, we
could lose license rights that are important to our business.

We are a party to a number of license agreements, including
with Nektar Therapeutics UK Limited and with Elan Pharma International Limited, pursuant to which we license key intellectual property, including intellectual property relating to our most advanced product candidate. These existing licenses impose
various diligence, milestone payment, royalty, insurance and other obligations on us. If we fail to comply with these obligations, the licensors may have the right to terminate the license, in which event we might not be able to develop or market
any product that is covered by the licensed patents. If we lose such license rights that are important to our product candidate, our business may be materially adversely affected. We may enter into additional licenses in the future and if we fail to
comply with obligations under those agreements, we could suffer similar consequences.

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 industries, 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 Employee Matters and Managing Growth

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

As of March 31, 2010, we had 92 full-time employees. We may need to expand our managerial, operational, administrative and other
resources in order to manage and fund our operations and clinical trials, continue our development activities and commercialize our product candidates. To support this growth, we may hire additional employees within the next 12 months. 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 Phase 3 clinical program for LEVADEX and other additional trials effectively, conducted with numerous vendors at numerous clinical sites;
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, scientific and clinical personnel in the future due to
competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the Silicon Valley area of California. If we are not able to attract and retain necessary personnel to 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 development,
regulatory, commercialization and product acquisition expertise of our senior management, particularly Timothy S. Nelson, our President and Chief Executive Officer, and Thomas A. Armer, our co-founder and Chief Scientific Officer. If we lose one or
more of these key employees, our ability to implement our business strategy successfully 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, obtain 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.

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. Because our business depends on certain key personnel and advisors, the loss of such personnel and advisors could weaken our management team and we may experience difficulty in
attracting and retaining qualified personnel and advisors.

Risks Relating to Owning Our Common Stock

Our executive officers, directors and principal stockholders have the ability to control all matters submitted to our stockholders for approval.

Our executive officers, directors and stockholders who own more than 5% of our outstanding common stock together control over
50% of our outstanding common stock. If these persons were to choose to act together, they would be able to control all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these persons, if they
choose to act together, will control the election of directors and approval of any merger, consolidation, sale of all or substantially all of our assets or other business combination or reorganization. This concentration of voting power could delay
or prevent an acquisition of us on terms that other stockholders may desire. The interests of this group of stockholders may not always coincide with your interests or the interests of other stockholders and they may act in a manner that advances
their best interests and not necessarily those of other stockholders, including obtaining a premium value for their common stock, and might affect the prevailing market price for our common stock.

Our share price may be volatile which may cause the value of our common stock to decline and subject us to securities class action litigation.

The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed
in this section, and others beyond our control, including:



| |  |  | actual or anticipated fluctuations in our financial condition and operating results;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | status and/or results of our clinical trials;
| | - |  | ---------------------------------------------



| |  |  | results of clinical trials of our competitors products;
| | - |  | --------------------------------------------------------



| |  |  | regulatory actions with respect to our products or our competitors products;
| | - |  | -----------------------------------------------------------------------------



| |  |  | actions and decisions by our collaborators or partners;
| | - |  | -------------------------------------------------------



| |  |  | actual or anticipated changes in our growth rate relative to our competitors;
| | - |  | -----------------------------------------------------------------------------



| |  |  | actual or anticipated fluctuations in our competitors operating results or changes in their growth rate;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | competition from existing products, new products or generics that may emerge;
| | - |  | -----------------------------------------------------------------------------



| |  |  | issuance of new or updated research or reports by securities analysts;
| | - |  | ----------------------------------------------------------------------



| |  |  | fluctuations in the valuation of companies perceived by investors to be comparable to us;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | market conditions for biopharmaceutical stocks in general; and
| | - |  | --------------------------------------------------------------



| |  |  | general economic and market conditions.
| | - |  | ---------------------------------------

As widely reported, financial markets in the United States, Europe and Asia have experienced extreme disruption, including, among other
things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations of others. Governments have taken unprecedented actions intended to address
extreme market conditions that include severely restricted credit and declines in real estate values. Fluctuations in the market prices of many equity securities often have been unrelated or disproportionate to the operating performance of those
companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of shares
of our common stock.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports
about our business, our stock price and trading volume could decline.

The trading market for our common stock depends on
the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our stock or change their opinion of our stock, our
stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to
decline.

##### Table of Contents

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 IPO continue to hold a substantial number of shares of our common
stock that they are now 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 or plan to register 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 establish programmed selling plans under Rule 10b5-1 of the Exchange Act 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 will continue to incur significant increased costs as a result of operating as a public company.

As a public company, we will continue to incur significant legal, accounting and other expenses to comply with the laws and regulations
affecting public companies, including the provisions of the Sarbanes-Oxley Act of 2002 and rules adopted by the Securities and Exchange Commission and by the NASDAQ Global Market. In addition, any changes in such regulations will result in increased
costs to us as we respond to these requirements. For example, we must use certain required internal controls and disclosure controls and procedures, as required by Section 404 of the Sarbanes-Oxley Act of 2002. Our testing, or the subsequent
testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. Our compliance with Section 404 will require that we incur
substantial accounting expense and expend significant management efforts. In addition, we will continue to bear all of the internal and external costs of preparing and distributing periodic public reports in compliance with our obligations under the
securities laws.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including
the Sarbanes-Oxley Act of 2002 and related regulations implemented by the Securities and Exchange Commission and The NASDAQ Global Market, are creating uncertainty for public companies, increasing legal and financial compliance costs and making some
activities more time consuming. We are currently evaluating and monitoring developments with respect to new and proposed rules and cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. These laws,
regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies.
This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We will continue to invest resources to comply with evolving laws, regulations and
standards, and this investment may result in increased general and administrative expenses and a diversion of managements time and attention from potentially revenue-generating activities to compliance activities. If our efforts to comply with
new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our
stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us. In addition,
these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the
members of our management team. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits, with some exceptions, stockholders owning in excess
of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents establish advanced notice requirements for nominations for election to our board of directors and for proposing matters that can be acted upon
at stockholder meetings. Although we believe these provisions together provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered
beneficial by some stockholders.

We have never paid dividends on our common stock, and because we do not anticipate paying any cash
dividends in the foreseeable future, capital appreciation, if any, of our common stock will be your sole source of gain on an investment in our stock.

We have never paid cash dividends on our common stock and we currently intend to retain our cash and 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. 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 biotechnology and biopharmaceutical 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.
