MAP PHARMACEUTICALS, INC.

(a development stage enterprise)

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. THE COMPANY

MAP Pharmaceuticals, Inc.,
incorporated in the state of Delaware, was originally 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. We have proprietary product candidates in clinical development that address large
market opportunities, including our most advanced product candidate, LEVADEX, formerly known as MAP0004, a proprietary orally inhaled version of dihydroergotamine for the potential treatment of migraine. Please refer to Note 8 Subsequent Event
for more information regarding Unit Dose Budesonide, or UDB, our proprietary nebulized version of budesonide for the potential treatment of asthma in children, and the impact of the termination of our license agreement with AstraZeneca, effective
July 8, 2009. 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 commercialization of LEVADEX and to fund the development and commercialization of our 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 balance sheet at December 31, 2008 has been derived from the audited financial statements at that date. 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, 2008, as amended.

Revenue Recognition

We recognize revenue in accordance with SEC Staff Accounting Bulletin, or
SAB, No. 104, Revenue Recognition. SAB No. 104 requires that certain criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the
fee is fixed or determinable; and collectability is reasonably assured. Determination of whether persuasive evidence of an arrangement exists and whether delivery has occurred or services have been rendered are based on managements judgments
regarding the fixed nature of the fee charged for research performed and milestones met, and the collectability of those fees. Should changes in conditions cause management to determine these criteria are not met for certain future transactions,
revenue recognized for any reporting period could be adversely affected.



Collaboration revenue, which is earned under agreements with third parties for research and development activities, may include nonrefundable license fees, cost reimbursements and contingent milestones and royalties. Our revenue
arrangements with multiple elements are evaluated under Emerging Issues Task Force, or EITF, Issue No. 00-21, Revenue Arrangements with Multiple Deliverables, and are divided into separate units of accounting if certain criteria are met,
including whether the delivered element has stand-alone value and whether there is verifiable objective and reliable evidence of the fair value of the undelivered items. The consideration we receive is allocated among the separate units based on
their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units.

##### Table of Contents

Upfront payments received upon execution of collaborative agreements are recorded as deferred revenue and
recognized as collaboration revenue over the research and development period pursuant to the agreement. Such period generally represents the research and development period set forth in the agreement between our third party collaborator and us. The
research and development period is estimated at the inception of the arrangement and is periodically reevaluated. Reevaluation of the research and development period may shorten or lengthen the period during which the deferred revenue is recognized.
We evaluate the appropriate period based on research progress attained and reevaluate the period when significant changes occur. If the collaboration agreement is terminated, all the remaining unamortized deferred revenue will be recognized as
collaboration revenue on the date of termination.

Cost reimbursements are based upon negotiated rates for our full time employee
equivalents, or FTE, and actual out-of-pocket costs. They are recognized as collaboration revenue as the related research and development services are performed. The cost reimbursements are generally based on qualified expenses as defined in the
collaborative agreement. FTE rates are intended to approximate our anticipated cost.

We recognize milestone payments as revenue upon
achievement of the milestone provided the milestone payment is nonrefundable, substantive effort and risk is involved in achieving the milestone and the amount of the milestone is reasonable in relation to the effort expended or risk associated with
the achievement of the milestone. If these conditions are not met, we defer the milestone payment and recognize it as revenue over the estimated period of performance under the contract as we complete our performance obligations.

Pre-clinical Study and Clinical Trial Accruals

We estimate our pre-clinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations that conduct and manage
pre-clinical studies and clinical trials on our behalf. The financial terms of these agreements vary from contract to contract and may result in uneven expenses and payment flows. Pre-clinical study and clinical trial expenses include the following:



| |  |  | fees paid to contract research organizations, or CROs, in connection with pre-clinical studies;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | fees paid to CROs and investigative sites in connection with clinical trials; and
| | - |  | ---------------------------------------------------------------------------------



| |  |  | fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for
use in pre-clinical studies and clinical trials.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Payments under some of these contracts depend on factors such as the
milestones accomplished, successful enrollment of certain number of patients, site initiation and completion of clinical trial milestones. In accruing services fees, we estimate the time period over which services will be performed and the level of
effort to be expended in each period. We monitor patient enrollment levels and related activities to the extent possible through internal reviews, correspondence and status meetings with CROs and review of contractual terms. Our estimates are
dependent on the timeliness and accuracy of data provided by our CROs and other vendors.

Share-Based Compensation

Effective January 1, 2006, we adopted Statement of Financial Accounting Standards, or SFAS, No. 123 (revised 2004),
Share-Based Payment, using the prospective transition method, which requires the measurement and recognition of compensation expense for all share-based payment awards granted, modified and settled to our employees and directors after
January 1, 2006. Our financial statements reflect the impact of SFAS No. 123(R). We chose the straight-line attribution method for allocating compensation costs and recognized the fair value of each stock option on a
straight-line basis over the requisite service period.

We account for equity instruments issued to non-employees in accordance with the
provisions of SFAS No. 123, Accounting for Stock-Based Compensation and EITF, No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services.
Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest.

Fair Value of Financial Instruments

The carrying amounts of certain of our financial instruments including cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value due to their short maturities.

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, unvested common shares subject to repurchase and warrants, 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.

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

Recent Accounting Pronouncements

In June 2009, the Financial Accounting Standards Board, or FASB, issued Statement No. 168, or SFAS No.168, The FASB Accounting Standards
Codification and the Hierarchy of Generally Accepted Accounting Principles. SFAS No.168 will become the single source of authoritative nongovernmental U.S. generally accepted accounting principles, or GAAP, superseding existing FASB, American
Institute of Certified Public Accountants, or AICPA, Emerging Issues Task Force, or EITF, and related accounting literature. SFAS No.168 reorganizes the thousands of GAAP pronouncements into roughly 90 accounting topics and displays them using a
consistent structure. Also included is relevant Securities and Exchange Commission guidance organized using the same topical structure in separate sections. SFAS No.168 will be effective for financial statements issued for reporting periods that end
after September 15, 2009. As a result, SFAS No.168 is effective for us in the third quarter of fiscal 2009. This will have an impact on our disclosures in the condensed consolidated financial statements since all future references to
authoritative accounting literature will be references in accordance with SFAS No.168.

In May 2009, FASB issued SFAS No. 165, Subsequent Events.SFAS No. 165 establishes
general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS No.165 requires entities to disclose the date through which they
have evaluated subsequent events and whether the date corresponds with the issuance of their financial statements. SFAS No. 165 is effective for interim and annual reporting periods ending after June 15, 2009. We adopted SFAS
No. 165 in the second quarter of fiscal 2009. The adoption of SFAS No. 165 did not have a material impact on our condensed consolidated financial statements.

In April 2009, the FASB issued FASB Staff Position, or FSP, FAS 157-4, Determining Fair Value When the Volume and Level of Activity
for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly. FSP FAS 157-4 provides guidelines for making fair value measurements more consistent with the principles presented in FASB Statement
No. 157, Fair Value Measurements. FSP FAS 157-4 relates to determining fair values when there is no active market or where the price inputs being used represent distressed sales. It reaffirms what FASB Statement No. 157 states is
the objective of fair value measurementto reflect how much an asset would be sold for in an orderly transaction (as opposed to a distressed or forced transaction) at the date of the financial statements under current market conditions.
Specifically, it reaffirms the need to use judgment to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. FSP FAS 157-4 is effective for interim and annual periods ending after
June 15, 2009. We adopted FSP FAS 157-4 in the second quarter of fiscal 2009. The adoption of FSP FAS 157-4 did not have a material impact on our condensed consolidated financial statements.

In April 2009, the FASB issued FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments. FSP FAS 107-1 and APB
28-1 enhance consistency in financial reporting by increasing the frequency of fair value disclosures. FSP FAS 107-1 and APB 28-1 relate to fair value disclosures for any financial instruments that are not currently reflected on the balance sheet of
companies at fair value. Prior to issuing this FSP, fair values for these assets and liabilities were disclosed only once a year. The FSP now requires these disclosures to be made on a quarterly basis, providing qualitative and quantitative
information about fair value estimates for all those financial instruments not measured on the balance sheet at fair value. FSP FAS 107-1 and APB 28-1 are effective for interim and annual periods ending after June 15, 2009. We adopted FSP FAS
107-1 and APB 28-1 in the second quarter of fiscal 2009. The adoption of FSP FAS 107-1 and APB 28-1 did not have a material impact on our condensed consolidated financial statements.

In April 2009, FASB issued FSP No. 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments.This FSP amends the
other-than-temporary impairment guidance in U.S. GAAP for debt securities to make the guidance more operational and to improve the presentation and disclosure of the other-than-temporary impairments on debt and equity securities in the financial
statements. The FSP is effective for interim and annual reporting periods ending after June 15, 2009. We adopted FSP No. 115-2 and FAS 124-2 in the second quarter of fiscal 2009. The adoption of FSP No. 115-2 and FAS 124-2 did not
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 AstraZeneca Agreement, which became effective in February 2009. Pursuant to the terms of the 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 this agreement, AstraZeneca paid us a nonrefundable upfront cash payment of $40 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.

We recognized
collaboration revenue of $8.6 million and $16.1 million, respectively, from AstraZeneca for the three and six months ended June 30, 2009, compared to $0 for the same periods in 2008. The collaboration revenue includes amortization of the
nonrefundable upfront payment of $40.0 million and reimbursement of qualified development expenses. The $40.0 million upfront payment has to date been recognized as collaboration revenue on a straight-line basis over the term of our research and
development period with respect to UDB. We received $44.1 million in cash for the cumulative period from July 3, 2003 (date of inception) to June 30, 2009.

On July 8, 2009, we received notice from AstraZeneca of the termination of the AstraZeneca Agreement, effective immediately. Please refer to Note 8 Subsequent Event for more information regarding the impact of
the termination of the AstraZeneca Agreement on our condensed consolidated financial statements.

Agreement with Nektar

In June 2004, we entered into an agreement, as amended, with Nektar Therapeutics UK Limited, or 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 June 30, 2009, we are required to make future nonrefundable milestone payments of up to $5.0 million related to products currently being developed under this agreement, when and if certain regulatory
and commercial milestones are met. We paid $0 for both the three and six months ended June 30, 2009 and 2008. We paid $2.6 million for the cumulative period from July 3, 2003 (date of inception) to June 30, 2009. Either party may
terminate the Nektar Agreement upon a material, uncured default of the other party. We may terminate the agreement, with or without cause, at any time upon six months prior written notice.

Agreement with Elan

In
April 2004, we entered into an agreement, as amended, with Elan Pharma International Limited, or Elan Agreement, Elan granted to us a worldwide, exclusive, sub-licensable license under Elans intellectual property rights to use, market,
distribute, sell, have sold, offer for sale, import and export certain ingredients for our UDB product candidate. We also agreed to pay royalties at specified rates based on net sales. As of June 30, 2009, we are required to make future
nonrefundable milestone payments of up to $16.5 million related to products currently being developed under this agreement, when and if certain regulatory and commercial milestones under the Elan Agreement are met with respect to our UDB product
candidate. We paid $0 for both the three and six months ended June 30, 2009, compared to $0.8 million and $0.8 million, respectively, for the same periods in 2008. We paid $4.0 million for the cumulative period from July 3, 2003 (date of
inception) to June 30, 2009. 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. In connection with the execution of the AstraZeneca Agreement, we amended the Elan agreements, pursuant to which AstraZeneca was granted certain rights to
exercise and enforce certain of our rights with Elan prior to the expiration or termination of the AstraZeneca Agreement. The amendments to the Elan agreements did not impact our unaudited condensed consolidated financial statements.

Please refer to Note 8 Subsequent Event for more information regarding the impact of the termination of the AstraZeneca Agreement on our condensed
consolidated financial statements.

NOTE 4. FAIR VALUE MEASUREMENTS

On January 1, 2008, we adopted SFAS, No. 157, Fair Value Measurements,or SFAS No. 157, as it relates to financial assets and
financial liabilities. In February 2008, the FASB issued FSP FAS 157-2, Effective Date of FASB Statement No. 157, which delayed the effective date of SFAS No. 157 for 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. SFAS No. 157 defines fair value, establishes a framework for measuring fair
value in GAAP and expands disclosures about fair value measurements.

SFAS No. 157 defines 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 SFAS No. 13, Accounting for Leases. SFAS No. 157 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
SFAS No. 157 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 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 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.

##### Table of Contents

The fair value of the Certificates of Deposit is classified as Level 2 due to the nature of a contractual
restriction related to our lease agreements.

The carrying amount for our debt reported in the consolidated balance sheet as of
June 30, 2009 is $17.9 million. Using a discounted cash flow technique that incorporates a market interest rate, we have determined the fair value of our debt to be $17.1 million at June 30, 2009.

Debt

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

In September 2006, we entered into a $10.0 million loan
facility agreement for the purpose of financing working capital, or 2006 Working Capital Loan, and borrowed all $10.0 million under the facility agreement during the year ended December 31, 2006. The 2006 Working Capital Loan bears interest at
an annual interest rate of 11.9% and matures in 2010. In May 2008, we entered into a new loan agreement, or 2008 Working Capital Loan, for $20.0 million in order to repay the 2006 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 the agreement. The 2008 Working Capital Loan has interest-only
payments up to and including January 2009, maturing in October 2011, and includes customary loan covenants. As of June 30, 2009, we were in compliance with the loan covenants. Expenses incurred in connection with the 2008 Working Capital Loan
were not material.

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

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 and in August 2006, we amended our lease agreement to include additional square footage within the same building. In March 2008,
we further amended our lease agreement, which we refer to as the March 2008 Amendment, to extend the term of the agreement until June 2012, and to include additional square footage and options to lease additional square footage. In September 2008,
we amended and restated the March 2008 Amendment, providing for expanded square footage and certain renewal options. The facility lease requires us to 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 leased under the amended and restated lease agreement were effective as of July 1,
2008.

Rent expense was approximately $0.3 million and $0.6 million, respectively, for the three and six months ended June 30, 2009,
compared to $0.2 million and $ 0.4 million, respectively, for the same periods in 2008. Rent expense was approximately $4.0 million for the cumulative period from July 3, 2003 (date of inception) to June 30, 2009.

As of June 30, 2009, future minimum lease payments are as follows (in thousands):

In accordance with the terms of the lease agreements 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 deposit account with the bank of $0.3 million at June 30, 2009 and December 31, 2008, which is shown as a restricted
investment on our unaudited condensed consolidated balance sheets.

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 general indemnifications. 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.

Stock-Based Compensation for Employees

The following table summarizes the stock-based compensation expense for stock options and our employee stock purchase plan that we recorded in the
condensed statements of operations in accordance with SFAS No.123(R) for the three and six months ended June 30, 2009 and 2008, respectively (in thousands):

We used the following assumptions to estimate the fair value of options granted under our stock
option plans for the three and six months ended June 30, 2009 and 2008, respectively:



|                         |  |                             |  |                           |  |             |  |

We used the following assumptions to estimate the fair value of shares purchased under our
employee stock purchase plan for the three and six months ended June 30, 2009 and 2008, respectively:



|                         |  |                             |  |                           |  |           |  |

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.

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 any significant 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 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 have not paid and do not anticipate paying any dividends in the near future, other than a certain cumulative dividend on preferred stock pursuant to the terms of our certificate of incorporation, which was paid in connection
with our initial public offering, or IPO.

Forfeitures:As stock-based compensation expense recognized in the condensed consolidated
statement of operations for the three and six months ended June 30, 2009 and 2008 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. SFAS No. 123(R) 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 June 30, 2009, there were unrecognized compensation costs of approximately $8.8 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 2.5 years.

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
$43,000 and $61,000, respectively, for the three and six months ended June 30, 2009, compared to $160,000 and $254,000, respectively, for the same periods in 2008. We recorded stock-based compensation expense for non-employees of $0.8 million
for the cumulative period from July 3, 2003 (date of inception) through June 30, 2009.

NOTE 8. SUBSEQUENT EVENT

In May 2009, the FASB issued SFAS No. 165, Subsequent Events.SFAS No. 165 establishes general standards of accounting for and
disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS No.165 requires entities to disclose the date through which they have evaluated subsequent events and
whether the date corresponds with the release of their financial statements. We have evaluated subsequent events through August 3, 2009, the date when we issued our condensed consolidated financial statements for the quarter ended June 30,
2009, and determined the following subsequent event to be disclosed.

On July 8, 2009, we received notice from AstraZeneca of the
termination of the AstraZeneca Agreement, effective immediately. AstraZeneca elected to terminate the AstraZeneca Agreement pursuant to Section 19.3.1(b) of the AstraZeneca Agreement, which provides that AstraZeneca could terminate the
AstraZeneca Agreement in the event that the primary endpoints of the initial Phase 3 clinical trial of UDB were not met. Effective on the date of termination, all rights licensed to AstraZeneca in the agreement reverted back to us. We also announced
our plan to suspend development of our UDB product candidate. We were jointly developing UDB in the United States with AstraZeneca, and were responsible for executing the development plan. The remaining unamortized deferred revenue of $33.1 million
of the nonrefundable upfront payment of $40 million received under the AstraZeneca Agreement as of June 30, 2009, will be recognized as collaboration revenue in the third quarter of fiscal 2009 as a result of the termination of this agreement.

The following discussion and analysis should be read in conjunction with the unaudited financial statements and notes thereto included in Part I,
Item 1 of this quarterly report on Form 10-Q and with the audited consolidated financial statements and related notes thereto included as part of our Annual Report on Form 10-K for the year ended December 31, 2008, as amended.

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 the clinical development stage that address large market opportunities, including our most advanced product candidate, LEVADEX, formerly known as MAP0004, our proprietary orally inhaled version of dihydroergotamine for the
potential treatment of migraine. LEVADEX is designed to provide faster onset and longer lasting pain relief than triptans, the class of drugs most often prescribed for treating migraine.

For our LEVADEX migraine program, we initiated a Phase 3 clinical program in July 2008 pursuant to a special protocol assessment, or SPA, from the U.S.
Food and Drug Administration, or FDA. In May 2009, we announced results of the efficacy portion of our first Phase 3 clinical trial of LEVADEX. We announced that 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.

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 LEVADE 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 expected, 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
multiplicity).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

There were no drug-related serious adverse events reported in the trial. 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 (0 percent), were rare and comparable to placebo. There were no changes in lung
function, as measured by spirometry, between the active and placebo groups.

In order to obtain regulatory approval for LEVADEX, we will
need to conduct additional Phase 3 and Phase 2 clinical trials. We anticipate initiating our second Phase 3 clinical trial of LEVADEX in the first quarter of 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 both inside
and outside of the United States.

In December 2008 we entered into a worldwide collaboration with AstraZeneca AB, or AstraZeneca
Agreement, to develop and commercialize Unit Dose Budesonide, or UDB, our proprietary nebulized version of budesonide for the potential treatment of asthma in children, 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, related to the
UDB product candidate, effective immediately. We announced plans to suspend 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.

In February 2009, under the terms of the AstraZeneca
Agreement, AstraZeneca paid us a nonrefundable upfront cash payment of $40.0 million. The $40.0 million upfront payment was recognized as collaboration revenue on a straight-line basis over the term of our research and development period with
respect to UDB. The remaining unamortized deferred revenue of $33.1 million as of June 30, 2009 will be recognized as collaboration revenue in the third quarter of fiscal 2009, as a result of the termination of this agreement.

Our product portfolio also includes two earlier stage product candidates, both of which, we believe, highlight the broad
applicability of our technologies to a diverse range of potential future products. MAP0005 is our proprietary combination of an inhaled corticosteroid and a long-acting beta-agonist for the potential treatment of asthma and chronic obstructive
pulmonary disease and MAP0001 is our proprietary form of insulin for the potential treatment of Type 1 and Type 2 diabetes via pulmonary delivery using our proprietary Tempo® inhaler. 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 partnership opportunities for further development and commercialization of these two product candidates.

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 $190.8 million as of June 30, 2009. We have financed
our operations through equity financing, debt financing, the issuance of convertible notes and collaboration payments. Prior to our initial public offering, or IPO, in October 2007, we received net proceeds of $106.7 million from the issuance of
convertible notes and convertible preferred stock. With the completion of our IPO we received net proceeds of $62.1 million after deducting expenses and underwriters discounts and commissions. In 2006, we entered into a loan facility
agreement and borrowed $10.0 million to finance working capital, or the 2006 Working Capital Loan, and a $1.0 million loan facility to finance equipment purchases. In May 2008, we entered into an agreement to borrow $20.0 million, or the 2008
Working Capital Loan, in order to repay the 2006 Working Capital Loan and to support general corporate purposes. We received $40.0 million as a nonrefundable upfront payment from AstraZeneca in February 2009.

We expect to continue to incur net losses for 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 clinical 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 Estimates

With the
exception of the Revenue Recognition policy discussed below, there have been no other significant changes in our critical accounting policies during the six months ended June 30, 2009, 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, 2008, as amended.

Revenue Recognition

We recognize revenue in accordance with SEC Staff Accounting Bulletin, or SAB, No. 104, Revenue Recognition. SAB No. 104 requires that certain criteria must be met before revenue can be
recognized: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the fee is fixed or determinable; and collectability is reasonably assured. Determination of whether persuasive evidence of an
arrangement exists and whether delivery has occurred or services have been rendered are based on managements judgments regarding the fixed nature of the fee charged for research performed and milestones met, and the collectability of those
fees. Should changes in conditions cause management to determine these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected.

Collaboration revenue, which is earned under agreements with third parties for research and development activities, may include nonrefundable license
fees, cost reimbursements and contingent milestones and royalties. Our revenue arrangements with multiple elements are evaluated under Emerging Issues Task Force, or EITF Issue No. 00-21, Revenue Arrangements with Multiple Deliverables,
and are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value and whether there is verifiable objective and reliable evidence of the fair value of the undelivered items.
The consideration we receive is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units.

Upfront payments received upon execution of collaborative agreements are recorded as deferred revenue and recognized as collaboration revenue over the
research and development period pursuant to the agreement. Such period generally represents the research and development period set forth in the agreement between our third party collaborator and us. Research and development period is estimated at
the inception of the arrangement and is periodically reevaluated. Reevaluation of the research and development period may shorten or lengthen the period during which the deferred revenue is recognized. We evaluate the appropriate period based on
research progress attained and reevaluate the period when significant changes occur. If the collaboration agreement is terminated, all the remaining unamortized deferred revenue will be recognized as collaboration revenue on the date of termination.

Cost reimbursements are based upon negotiated rates for our full time employee equivalents, or FTE, and actual out-of-pocket costs. They
are recognized as collaboration revenue as the related research and development services are performed. The cost reimbursements are generally based on qualified expenses as defined in the collaborative agreement. FTE rates are intended to
approximate our anticipated cost.

We recognize milestone payments as revenue upon achievement of the milestone provided the milestone
payment is nonrefundable, substantive effort and risk is involved in achieving the milestone and the amount of the milestone is reasonable in relation to the effort expended or risk associated with the achievement of the milestone. If these
conditions are not met, we defer the milestone payment and recognize it as revenue over the estimated period of performance under the contract as we complete our performance obligations.

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. Total collaboration revenue recognized under the AstraZeneca Agreement was $8.6 million and $16.1 million, respectively,
for the three and six months ended June 30, 2009, compared to $0 for the same periods in 2008.

The $40.0 million upfront payment
received from AstraZeneca under the AstraZeneca Agreement terminated in July 2009 was being recognized as collaboration revenue on a straight-line basis over the term of research and development period with respect to UDB. The remaining unamortized
deferred revenue of $33.1 million as of June 30, 2009 will be recognized as collaboration revenue in the third quarter of fiscal 2009.

Research
and Development Expenses

Research and development expenses consist of: (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.

##### Table of Contents

Conducting a significant amount of research and development is central to our business model. Through
June 30, 2009, we incurred approximately $155.4 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 clinical trials. We plan to increase our 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, effective February 2, 2009, AstraZeneca began reimbursing us for the development costs related to the UDB
program.

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 and six months ended June 30, 2009 and 2008, 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 is 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 share-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 June 30, 2009, we incurred approximately $40.3 million in sales, general and administrative expenses since our inception in 2003.

##### Table of Contents

The increase in collaboration revenue was due to the AstraZeneca Agreement, which became effective on
February 2, 2009. The $40.0 million upfront payment received from AstraZeneca was being recognized as collaboration revenue on a straight-line basis over the term of research and development period with respect to UDB. As a result of the
termination of the AstraZeneca Agreement effective July 2009, the remaining unamortized deferred revenue of $33.1 million as of June 30, 2009, will be recognized as collaboration revenue in the third quarter of fiscal 2009.

For the three months ended June 30, 2009 compared to the same period in 2008, the decrease in
research and development expenses was driven primarily by a decrease of $5.1 million in clinical and other project expenses to support the UDB Phase 3 clinical program, partially offset by an increase of $1.2 million in clinical and other project
expenses to support the LEVADEX Phase 3 clinical program and an increase of $0.8 million in personnel related expenses to support these clinical programs. In July 2009, following AstraZenecas decision to terminate the AstraZeneca
Agreement, we announced our plan to suspend development of our UDB product candidate.

For the six months ended June 30, 2009 compared
to the same period in 2008, the decrease in research and development expenses was driven primarily by a decrease of $4.7 million in clinical and other project expenses to support the UDB Phase 3 clinical program, partially offset by an increase of
$2.8 million in clinical and other project expenses to support the LEVADEX Phase 3 clinical program, and an increase of $1.2 million in personnel related expenses to support these clinical programs.

For the three and six months ended June 30, 2009, research and development expenses reflected a one-time credit of $0.8 million from one of our
vendors, respectively.

For the three months ended June 30, 2009 compared to the same period in 2008, the increase in
sales, general and administrative expenses was related primarily to an increase of $0.1 million in personnel related expenses, an increase of $0.1 million in stock-based compensation and an increase of $0.1 million in other miscellaneous fees.

For the six months ended June 30, 2009 compared to the same period in 2008, the decrease in sales, general and administrative
expenses was related primarily to a decrease of $0.4 million in professional services and a decrease of $0.1 million in other miscellaneous fees, offset by an increase of $0.5 million in stock-based compensation.

##### Table of Contents

For the three and six months ended June 30, 2009 compared to the same periods in 2008, interest
income decreased due primarily to a decrease in market interest rates, as well as the decreased cash, cash equivalents and short-term investment balances at June 30, 2009 as compared to those at June 30, 2008.

We expect our interest income to fluctuate in the future due to changes in market interest rates and average investment balances.

Interest expense for the three months ended June 30, 2009 compared to the same period in 2008
was relatively unchanged. Interest expense increased for the six months ended June 30, 2009 as compared to the same period in 2008 due primarily to higher debt balances related to the 2008 Working Capital Loan.

We expect our interest expense to fluctuate in the future with average debt balances.

Other Expense

Other expense and
percentage changes as compared to the prior year are as follows (dollar amounts are presented in thousands):

In the second quarter of 2008, we incurred a debt issuance cost of $394,000 upon the retirement of
the 2006 Working Capital Loan and commencement of the 2008 Working Capital Loan. We did not incur such expenses in the second quarter of 2009 and, as a result, there was a decrease in other expense for the three and six months ended June 30,
2009 compared to the same periods in 2008.

Liquidity and Capital Resources

Liquidity

We have incurred losses since our inception in July 2003 and as of June 30,
2009 we had an accumulated deficit of $190.8 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 the next several years. We expect to
incur increased research and development and sales, general and administrative expenses related to our development 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. 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. With the completion of our IPO we received net proceeds of
$62.1 million after deducting expenses and underwriters discounts and commissions. In 2006, we entered into the 2006 Working Capital Loan, and a $1.0 million loan facility to finance equipment purchases. In May 2008, we entered into the
2008 Working Capital Loan, in order to repay the 2006 Working Capital Loan and to support general corporate purposes. We received $40.0 million as a nonrefundable upfront payment from AstraZeneca in February 2009 and $4.1 million in cash for
reimbursement of qualified development expenses during 2009. On July 8, 2009, we received notice from AstraZeneca of the termination of the license agreement, effective immediately.

As of June 30, 2009, we had approximately $54.8 million in cash and cash equivalents. Our cash and cash equivalents are primarily held 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 Flow

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



|                            |  |                           |        |   |      |   |         |

|Cash provided by (used in): |  |                           |        |   |      |   |         |

Net cash provided by (used in) operating activities. We received $12.7 million of cash
from operating activities for the six months ended June 30, 2009 compared to the usage of cash of $27.9 million for the same period in 2008. The cash provided by operating activities for the six months ended June 30, 2009 was due primarily
to a $40.0 million nonrefundable upfront payment we received from AstraZeneca, partially offset by a net loss of $14.9 million for the six months ended June 30, 2009 and by an increase in accounts receivable of $5.2 million from AstraZeneca.
The usage of cash of $27.9 million for the six months ended June 30, 2008 was due primarily to a net loss of $30.8 million, partially offset by stock-based compensation of $2.0 million and an increase in accrued liabilities of $0.8 million.

Net cash provided by (used in) investing activities. We received $12.5 million of cash from investing activities for the
six months ended June 30, 2009 compared to the usage of cash of $4.8 million for the same period in 2008. Net cash provided by investing activities for the six months ended June 30, 2009 was due primarily to sales and maturities of our
short-term investments of $12.7 million. Net cash used in investing activities for the six months ended June 30, 2008 was primarily related to investment activity, with more purchases than sales and maturities of investments.

Net cash provided by (used in) financing activities. We used $2.4 million of cash in financing activities for the six months ended
June 30, 2009 compared to receiving cash of $10.7 million for the same period in 2008. The cash usage for the six months ended June 30, 2009 was due primarily to higher repayments made on outstanding debt. The cash provided by financing
activities for the six months ended June 30, 2008 was primarily attributable to the issuance of $20.0 million in debt in May 2008, offset by the repayment of $8.3 million for the 2006 Working Capital Loan.

Agreement with AstraZeneca

In December 2008,
we entered into the AstraZeneca Agreement, which became effective in February 2009. Pursuant to the terms of the 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 this agreement, AstraZeneca paid us a nonrefundable upfront cash payment of $40 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.

We recognized collaboration revenue of $8.6 million and $16.1 million, respectively, from AstraZeneca for the three and six
months ended June 30, 2009, compared to $0 for the same periods in 2008. The collaboration revenue includes amortization of the nonrefundable upfront payment of $40.0 million and reimbursement of qualified development expenses. The $40.0
million upfront payment has to date been recognized as collaboration revenue on a straight-line basis over the term of our research and development period with respect to UDB. We received $44.1 million in cash for the cumulative period from
July 3, 2003 (date of inception) to June 30, 2009.

On July 8, 2009, we received notice from AstraZeneca of the termination
of the AstraZeneca Agreement, effective immediately.

Agreement with Nektar

Under the June 2004 agreement, as amended, with Nektar Therapeutics UK Limited, or 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 June 30, 2009, we are required to make future nonrefundable milestone payments of up to $5.0 million related to products currently being developed under this agreement, when and if certain regulatory and commercial milestones
are met. We paid $0 for both the three and six months ended June 30, 2009 and 2008. We paid $2.6 million for the cumulative period from July 3, 2003 (date of inception) to June 30, 2009. Either party may terminate the Nektar Agreement
upon a material, uncured default of the other party. We may terminate the 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 Elan Agreement, Elan granted to us a worldwide, exclusive, sub-licensable license under Elans intellectual property
rights to use, market, distribute, sell, have sold, offer for sale, import and export certain ingredients for our UDB product candidate. We also agreed to pay royalties at specified rates based on net sales. As of June 30, 2009, we are required
to make future nonrefundable milestone payments of up to $16.5 million related to products currently being developed under this agreement, when and if certain regulatory and commercial milestones under the Elan Agreement are met with respect to our
UDB product candidate. We paid $0 for both the three and six months ended June 30, 2009, compared to $0.8 million and $0.8 million, respectively, for the same periods in 2008. We paid $4.0 million for the cumulative period from July 3,
2003 (date of inception) to June 30, 2009. 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. In connection with the execution of the AstraZeneca Agreement, we amended the Elan agreements, pursuant to which AstraZeneca was granted
certain rights to exercise and enforce certain of our rights with Elan prior to the expiration or termination of the AstraZeneca Agreement. The amendments to the Elan agreements did not impact our unaudited condensed consolidated financial
statements.

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, the timing and the cost of regulatory approvals;
| | - |  | -------------------------------------------------------------



| |  |  | 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;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | 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 our 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.

As widely reported,
financial markets in the United States, Europe and Asia have been experiencing extreme disruption in recent months, 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. Concern
about the stability of the markets generally and the strength of counterparties specifically has led many lenders and institutional investors to reduce, and in some cases, cease to provide funding to borrowers. Continued turbulence in the U.S. and
international markets and economies may limit our ability to access the capital markets to meet our funding requirements. 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 June 2009, the Financial Accounting Standards Board, or FASB , or FASB, issued Statement No. 168, or SFAS No.168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted
Accounting Principles. SFAS No.168 will become the single source of authoritative nongovernmental U.S. generally accepted accounting principles, or GAAP, superseding existing FASB, American Institute of Certified Public Accountants, or AICPA,
Emerging Issues Task Force, or EITF, and related accounting literature. SFAS No.168 reorganizes the thousands of GAAP pronouncements into roughly 90 accounting topics and displays them using a consistent structure. Also included is relevant
Securities and Exchange Commission guidance organized using the same topical structure in separate sections. SFAS No.168 will be effective for financial statements issued for reporting periods that end after September 15, 2009. As a result,
SFAS No.168 is effective for us in the third quarter of fiscal 2009. This will have an impact on our disclosures in the condensed consolidated financial statements since all future references to authoritative accounting literature will be references
in accordance with SFAS No.168.

In May 2009, the FASB issued SFAS No. 165, Subsequent Events.SFAS No. 165
establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS No.165 requires entities to disclose the date
through which they have evaluated subsequent events and whether the date corresponds with the issuance of their financial statements. SFAS No. 165 is effective for interim and annual reporting periods ending after June 15, 2009. We
adopted SFAS No. 165 in the second quarter of fiscal 2009. The adoption of SFAS No. 165 did not have a material impact on our condensed consolidated financial statements.

In April 2009, the FASB issued FASB Staff Position, or FSP, FAS 157-4, Determining Fair Value When the Volume and Level of Activity
for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly. FSP FAS 157-4 provides guidelines for making fair value measurements more consistent with the principles presented in FASB Statement
No. 157, Fair Value Measurements. FSP FAS 157-4 relates to determining fair values when there is no active market or where the price inputs being used represent distressed sales. It reaffirms what FASB Statement No. 157 states is
the objective of fair value measurementto reflect how much an asset would be sold for in an orderly transaction (as opposed to a distressed or forced transaction) at the date of the financial statements under current market conditions.
Specifically, it reaffirms the need to use judgment to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. FSP FAS 157-4 is effective for interim and annual periods ending after
June 15, 2009. We adopted FSP FAS 157-4 in the second quarter of fiscal 2009. The adoption of FSP FAS 157-4 did not have a material impact on our condensed consolidated financial statements.

In April 2009, the FASB issued FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments. FSP FAS 107-1 and APB
28-1 enhance consistency in financial reporting by increasing the frequency of fair value disclosures. FSP FAS 107-1 and APB 28-1 relate to fair value disclosures for any financial instruments that are not currently reflected on the balance sheet of
companies at fair value. Prior to issuing this FSP, fair values for these assets and liabilities were disclosed only once a year. The FSP now requires these disclosures to be made on a quarterly basis, providing qualitative and quantitative
information about fair value estimates for all those financial instruments not measured on the balance sheet at fair value. FSP FAS 107-1 and APB 28-1 are effective for interim and annual periods ending after June 15, 2009. We adopted FSP FAS
107-1 and APB 28-1 in the second quarter of fiscal 2009. The adoption of FSP FAS 107-1 and APB 28-1 did not have a material impact on our condensed consolidated financial statements.

In April 2009, FASB issued FSP No. 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments.This FSP amends the
other-than-temporary impairment guidance in U.S. GAAP for debt securities to make the guidance more operational and to improve the presentation and disclosure of the other-than-temporary impairments on debt and equity securities in the financial
statements. The FSP is effective for interim and annual reporting periods ending after June 15, 2009. We adopted FSP No. 115-2 and FAS 124-2 in the second quarter of fiscal 2009. The adoption of FSP No. 115-2 and FAS 124-2 did not
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 and six months ended June 30, 2009.

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 $25.8 million, $40.1 million and $72.9 million, for the years ended December 31, 2006, 2007 and 2008, respectively. As of
June 30, 2009, we had a deficit accumulated during development stage of approximately $190.8 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 our expenses to increase 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 incur substantial and increasing 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 increased 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, debt financings and collaboration payments. 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, effective immediately, of our license agreement with AstraZeneca 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 UDB development activities conducted
for the U.S. registration, subject to the terms and conditions of the license agreement. Following the termination of the license 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;
|- |  | ---------------------------------------------------------------------------



| |  | the need to obtain regulatory approval of our most advanced product candidate, LEVADEX for migraine;
|- |  | ----------------------------------------------------------------------------------------------------

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 our research and development expenses to increase in connection with our ongoing activities, particularly as we focus on and proceed with
our Phase 3 clinical program and conduct our other clinical trials 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 our 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.

As widely reported, financial markets in the United States, Europe and Asia have been experiencing
extreme disruption in recent months, 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. Concern about the stability of the markets generally and the strength of
counterparties specifically has led many lenders and institutional investors to reduce, and in some cases, cease to provide funding to borrowers. Continued turbulence in the U.S. and international markets and economies may limit our ability to
access the capital markets to meet our funding requirements.

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 outsourced 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 UDB and LEVADEX. We recently announced that we are suspending development of UDB, after our partner AstraZeneca terminated our license agreement. 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. Our contract with AstraZeneca provided a right of termination in the
event that the trial failed to meet its co-primary endpoints and in July 2009, AstraZeneca notified us of the termination of the collaboration, effective immediately. 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 and regulatory
approval 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 subset of subjects from this trial are continuing in a long-term safety extension of the study and we
are continuing to recruit and enroll subjects in the safety extension. We also expect to conduct a second, confirmatory Phase 3 clinical trial as well as additional Phase 2 trials, including a pharmacokinetic trial in approximately 24 adult smokers
comparing them to non-smokers and a pharmacodynamic trial in approximately 24 healthy adults compared to placebo, studying echocardiographic effects, of LEVADEX before submitting an application to the FDA for regulatory approval. 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 any product candidates. Any failure to obtain regulatory approval of LEVADEX would have a material and adverse impact on our business.

With the suspension of development for our UDB product candidate, LEVADEX is our only current product
candidate in late stage development. Our drug discovery 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;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disputes may arise between us and our partners that result in the delay or termination of the research, development or commercialization of our product
candidates or that result in costly litigation or arbitration that diverts managements attention and resources;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | partners may experience financial difficulties;
| | - |  | -----------------------------------------------



| |  |  | partners may not properly maintain or defend our intellectual property rights, or may use our proprietary information, in such a way as to invite litigation
that could jeopardize or invalidate our intellectual property rights or proprietary information or expose us to potential litigation;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | business combinations or significant changes in a partners business strategy may adversely affect a partners willingness or ability to complete
its obligations under any arrangement;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a partner could independently move forward with a competing product candidate developed either independently or in collaboration with others, including our
competitors; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the collaborations with our partners may be terminated or allowed to expire, which would delay the development and may increase the cost of developing our
product candidates.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 the incurrence of unforeseen costs due to enrollment delays, requirements to conduct additional
trials and studies and increased expenses associated with the services of our CROs and other third parties.

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 currently are conducting a Phase 3 clinical program for LEVADEX and will need to conduct additional Phase 3 and Phase 2 clinical trials in order to obtain regulatory approval for this product candidate. 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 first Phase 3
trial of LEVADEX, indicating that the trial met all four of its co-primary endpoints when LEVADEX was compared to placebo. A subset of subjects from this trial is continuing in a long-term safety extension of the study and we are continuing to
recruit and enroll subjects for this safety extension. In order to obtain regulatory approval for LEVADEX, we will need to conduct additional Phase 3 and Phase 2 clinical trials. 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 Phase 3 or other clinical trials we may conduct will demonstrate adequate efficacy

and safety to result in regulatory approval to market our product candidates. For example, 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, AstraZeneca terminated our collaboration. We have suspended development of our UDB product
candidate.

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 initial Phase 3 clinical trial indicated that the trial failed to
meet the primary endpoints. 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 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. 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-to-drug interactions that could
impact potential product safety. At this point in time, we have not been requested to perform drug-to-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.

While we have negotiated an SPA
with the FDA for our first Phase 3 clinical trial of LEVADEX for the potential treatment of migraine, the SPA does not guarantee any particular outcome from regulatory review of the study or the product candidate.

The FDAs SPA process creates a written agreement between the sponsoring company and the FDA regarding clinical trial design and other clinical trial
issues that can be used to support approval of a product candidate. The SPA is intended to provide assurance that if the agreed upon clinical trial protocols are followed and the trial endpoints are achieved, the data may serve as the primary basis
for an efficacy claim in support of an NDA. However, the SPA agreement is not a guarantee of an approval of a product or any permissible claims about the product. In particular, the SPA is not binding on the FDA if public health concerns
unrecognized at the time of the SPA agreement is entered into become evident, other new scientific concerns regarding product safety or efficacy arise or if the sponsor company fails to comply with the agreed upon trial protocols. In January 2008,
we announced that we reached agreement with the FDA on a SPA for the first Phase 3 clinical trial of our LEVADEX product candidate for the potential treatment of migraine. 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 subset of subjects from this trial is continuing in a long-term safety extension of the study and we are continuing to
recruit and enroll subjects for this safety extension of the study. We cannot assure you that the safety extension of the Phase 3 clinical trial will be successful. In addition, we do not know how the FDA will interpret the commitments under the SPA
agreement, how it will interpret the data and results or whether it will approve our LEVADEX product candidate for the treatment of migraine. As a result, we cannot guarantee any particular outcome from regulatory review of the first LEVADEX Phase 3
trial.

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 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 therapeutics 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 Imitrex from

##### Table of Contents

GlaxoSmithKline, with 2007 sales of approximately $1.2 billion in the United States and $1.6 billion worldwide, according to data published by IMS Health.
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. Alternative formulations of
dihydroergotamine, or DHE include Migranal, which is nasally delivered, and which may become generically available prior to commercial introduction, if at all, 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 migraine and compete with LEVADEX.

In addition, we 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, a contraindication or field alerts to physicians and pharmacies;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



34

##### Table of Contents

| |  |  | 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 current Good Manufacturing Practices, or cGMPs, 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.
| | - |  | -----------------------------------------------------

##### Table of Contents

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;
| | - |  | ----------------------------



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



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



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



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



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 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. 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 license
agreement with AstraZeneca related to our UDB product candidate. Our agreement with AstraZeneca provided that AstraZeneca could terminate the agreement in the event that the primary endpoints of our initial Phase 3 clinical trial of UDB were not
met. Following the termination of the license 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.

##### Table of Contents

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 Elan Pharma International Limited and with Nektar Therapeutics UK
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 June 30, 2009, we had 95 full-time employees. We may need to continue to expand our managerial, operational, administrative financial 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, which we anticipate will be 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 and 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 approximately 71% 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 been experiencing extreme disruption in recent months, 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.

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.
