NOTE 1. THE COMPANY AND BASIS OF PRESENTATION

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. We 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 several proprietary product candidates in clinical development that address large market opportunities, including our two most advanced product candidates: a proprietary formulation of nebulized budesonide for the
potential treatment of pediatric asthma in children from 12 months to eight years of age; and a proprietary orally inhaled version of dihydroergotamine for the potential treatment of migraine. We are in the development stage and since inception have

In October 2007, we
completed our initial public offering (IPO) of 5,750,000 shares of common stock at a public offering price of $12.00 per share. The aggregate net cash proceeds from the IPO were approximately $62.1 million, after deducting the underwriting discount
and commissions and other offering expenses. In connection with the IPO, all outstanding redeemable convertible preferred stock converted into common stock, warrants to purchase convertible preferred stock converted into warrants to purchase common
stock, and redeemable convertible preferred stock warrant liability was reclassified to equity.

We have incurred losses since our
inception in July 2003. Prior to achieving profitable operations, we intend to continue to fund operations through public or private financings, strategic partnerships or other arrangements.

Basis of Presentation

We have
prepared the accompanying interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America 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 presentation 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, 2007 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, 2007.

Reverse Stock Split

We initiated a 1-for-1.77 reverse stock split effective October 4, 2007. All shares and per share amounts in these condensed consolidated financial statements and notes thereto have been retroactively adjusted to
give effect to the reverse stock split.

Recent Accounting Pronouncements

We adopted Emerging Issues Task Force (EITF) Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in
Future Research and Development Activities, on a prospective basis for new contracts entered into on or after January 1, 2008. EITF Issue No. 07-3 states that nonrefundable advance payments for future research and development
activities should be deferred and recognized as an expense as the goods are delivered or the related services are performed. Entities should then continue to evaluate whether they expect the goods to be delivered or services to be rendered and, if
an entity does not expect the goods to be delivered or services to be rendered, the capitalized advance payment should be charged to expense. The adoption of EITF Issue No. 07-3 did not have a material effect on our financial position or
results of operations.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting
Standards (SFAS) No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value
measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2 -
Effective Date of FASB Statement No. 157) which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a
recurring basis (at least annually) to fiscal years beginning after November 15, 2008. The adoption of SFAS 157 for financial assets and liabilities did not have a material impact on our condensed consolidated financial position, results of
operations or cash flows. Please see Note 2. Certain Balance Sheet Components.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and
Financial Liabilities (SFAS 159) effective for us January 1, 2008. SFAS 159 permits companies to choose to measure certain financial instruments and other items at fair value. We chose not to elect the fair value option for financial
assets and liabilities existing at January 1, 2008, and did not elect the fair value option on financial assets and liabilities transacted in the three months ended March 31, 2008. Therefore, the adoption of SFAS 159 had no impact on our
financial position or results of operations.

SFAS 157 clarifies that fair value is an exit price, representing the amount that would be
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use
in pricing an asset or liability. As a basis for considering such assumptions, SFAS 157 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted
prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require us to develop
our own assumptions. This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure our marketable securities at fair value.

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

Fair value hierarchy of our marketable securities at fair value in connection with the adoption of SFAS 157 are summarized as follows (in thousands):



|                                      |  |                    |  |                                                            |  |

As of March 31, 2008, we applied Level 2 measurements to our holdings of commercial paper
with maturity dates less than three months classified under cash equivalents. Commercial paper with maturity dates less than three months are valued at the quoted market price from broker or dealer quotations.

We chose not to elect the fair value option as prescribed by SFAS 159 for our financial assets and liabilities that had not been previously carried at
fair value. Therefore, financial assets and liabilities not carried at fair value, such as short- and long-term debt and accounts payable are still reported at their carrying values.

NOTE 3. COMMITMENTS AND CONTINGENCIES

Long-term Debt

In September
2006, we entered into a $10.0 million loan facility agreement for the purpose of financing working capital (the Working Capital Loan) and borrowed all $10.0 million under the facility agreement during the year ended December 31, 2006. The
Working Capital Loan bears interest at an annual interest rate of 11.9% and matures in 2010. Additionally, in September 2006, we entered into a $3.0 million loan facility agreement for the purpose of financing equipment purchases (the 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 2009. Subsequent to March 31, 2008, in May 2008 we entered into a new loan agreement (2008
Loan) for $20.0 million. Please see Note 7. Subsequent Events, for additional information.

In connection with the loan facility
agreements entered into in 2006, we issued warrants to purchase convertible preferred stock. The fair value of the warrants was estimated at an aggregate of approximately $300,000 using the Black-Scholes valuation model at the dates of issuance and
recorded as debt issuance costs that are amortized to interest expense over the contractual life of 7 years. The fair value of the warrants outstanding was recorded as a liability as of September 30, 2006 and revalued each subsequent reporting
period with the resulting gains and losses recorded in other expense which is classified in other income (expense), net. We continued to adjust the liability for changes in fair value until the completion of our IPO, at which time all unexercised
warrants converted into warrants to purchase common stock and the liability was reclassified to equity. In accordance with the revaluation through the date of the IPO, we recorded expense of approximately $0.3 million for the three months ended
March 31, 2007 and approximately $0.6 million for the cumulative period from July 3, 2003 (date of inception) to March 31, 2008.

Operating Leases

In June 2004, we entered into a lease agreement for laboratory and office facilities in
Mountain View, California and in August 2006 amended our lease agreement to include additional square footage within the same building, expiring in June 2008. In March 2008, we further amended our lease agreement to extend the agreement until
June 2012, and to include additional square footage and options to lease additional square footage. Rent is subject to an annual increase for the duration of the lease. The annual lease payments for this space under the new lease agreement are
approximately $0.7 million in 2008, $1.3 million in 2009 and 2010, $1.4 million in 2011 and $0.7 million 2012.

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
March 31, 2008 and December 31, 2007, which is shown as a restricted investment on the 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 such capacity. There have been no claims to date and we have a director and officer insurance policy that enables us to recover a portion of any amounts paid for future
potential claims.

NOTE 4. LICENSE AND SUPPLY AGREEMENTS

Under the June 2004 agreement, as amended, with Nektar Therapeutics UK Limited (the Nektar Agreement), we were granted a worldwide, exclusive license, with a right to sublicense, under Nektar patents and
know-how, to develop and commercialize any formulation of a form of dihydroergotamine for administration by inhalation using a device. We also agreed to pay royalties at specified rates based on net sales. As of March 31, 2008, 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. No amounts related to milestones were paid
during the first quarter ended March 31, 2008 and 2007, and we paid $2.6 million during the cumulative period from July 3, 2003 (date of inception) to March 31, 2008. 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 written notice.

Under the April 2004 agreement, as amended, with Elan Pharma International Limited (the Elan
Agreement), Elan granted to us a worldwide, exclusive, sub-licensable license under Elans intellectual property rights to use, market, distribute, sell, import and export ingredients for our UDB product candidate. We also agreed to pay
royalties at specified rates based on net sales. As of March 31, 2008, 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 are met with respect to our UDB product candidate. We paid $750,000 and $0 related to milestones for the first quarter ended 2008 and 2007, respectively, and $4.0 million during the cumulative period from
July 3, 2003 (date of inception) to March 31, 2008. 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
written notice.

Under the September 2005 agreement with Eiffel Technologies Limited (the Eiffel Agreement), Eiffel agreed to research
and develop certain methods for manufacturing formulations for steroids, steroid beta-agonist combinations or insulin. Eiffel agreed to manufacture pre-clinical and clinical supplies of such formulations and granted to us an exclusive, worldwide,
sub-licensable license under certain of its intellectual property rights to develop, use, make, sell, export and import the formulations it develops under the Eiffel Agreement. We also agreed to pay royalties at specified rates based on net sales
and a percentage of sublicense fees. As of March 31, 2008, the Eiffel Agreement requires us to make future nonrefundable milestone payments to Eiffel of up to $10.8 million related to products currently being developed under this agreement,
when and if certain development milestones related to clinical development and regulatory progress are met. No amounts related to milestones were paid during the first quarter ended March 31, 2008 and 2007, and we paid $250,000 during the
cumulative period from July 3, 2003 (date of inception) to March 31, 2008. Either party may terminate the Eiffel Agreement upon a material, uncured default of the other party or if the other party becomes insolvent. We may terminate the
Eiffel Agreement, with or without cause, at any time upon three months written notice.

NOTE 5. EMPLOYEE EQUITY INCENTIVE PLANS

Stock-based Compensation

We account for employee stock-based compensation under SFAS No. 123(R), Share-Based Payment (SFAS 123R), which requires compensation expense related to share-based transactions, including employee
stock options, to be measured and recognized in the financial statements based on fair value. Employee stock-based compensation expense recognized in the three months ended March 31, 2008 and 2007 was calculated based on awards ultimately
expected to vest, and has been reduced for estimated forfeitures. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Stockbased compensation expense recognized under SFAS 123R related to stock options and awards under our employee stock purchase plan (ESPP) is as
follows (in thousands):

Stock Option Awards

During the three months ended March 31, 2008 and 2007, we granted 612,400 and 323,929 stock options, respectively, to employees with a
weighted-average grant date fair value of $7.34 and $6.84 per share, respectively. The fair value of stock option grants was estimated at the grant date using the BlackScholes option valuation model with the following weighted-average
assumptions:

As of March 31, 2008, there was unrecognized compensation costs of approximately
$9.1 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 3.2 years.

Employee Stock Purchase Plan

We also estimated the fair value of employee stock purchase rights granted under the ESPP, which became effective in October 2007 upon the effectiveness of the IPO, using the Black-Scholes valuation model. For the three months ended
March 31, 2008, the weighted-average fair value of each stock purchase right was $5.26 per share. The fair value of employee stock purchase rights is being recognized on a straight-line basis over the requisite service period of the purchase
rights.

NOTE 6. 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, convertible preferred stock 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):

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

This quarterly report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, which are subject to the safe harbor created by those sections. Forward-looking statements are based on our managements beliefs
and assumptions and on information currently available to them. In some cases you can identify forward-looking statements by words such as may, will, should, could, would,
expect, plans, anticipates, believes, estimates, projects, predicts, potential and similar expressions intended to identify forward-looking statements.
Examples of these statements include, but are not limited to, statements regarding: the implications of interim or final results of our clinical trials, the progress of our research programs, including clinical testing, the extent to which our
issued and pending patents may protect our products and technology, our ability to identify new product candidates, the potential of such product candidates to lead to the development of commercial products, our anticipated timing for initiation or
completion of our clinical trials for any of our product candidates, our future operating expenses, our future losses, our future expenditures for research and development, and the sufficiency of our cash resources. Our actual results could differ
materially from those anticipated in these forward-looking statements for many reasons, including the risks faced by us and described in Part II, Item 1A of this quarterly report on Form 10-Q and our other filings with the SEC. You should not
place undue reliance on these forward-looking statements, which apply only as of the date of this quarterly report on Form 10-Q. You should read this quarterly report on Form 10-Q completely and with the understanding that our actual future results
may be materially different from those we expect. Except as required by law, we assume no obligation to update these forward-looking statements, whether as a result of new information, future events or otherwise.

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.

Overview

We 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 several proprietary product candidates in clinical development which address large market opportunities, including our two most advanced product candidates, Unit Dose Budesonide, or UDB, for pediatric asthma and
MAP0004 for migraine. UDB is our proprietary nebulized version of budesonide intended to treat pediatric asthma in children from 12 months to eight years of age. UDB is designed to be administered more quickly and to provide efficacy at lower doses
than conventional nebulized budesonide, which is the current leading treatment for pediatric asthma. MAP0004 is our proprietary orally inhaled version of dihydroergotamine intended to treat migraine. MAP0004 is designed to provide faster onset and
longer lasting pain relief than triptans, the class of drugs most often prescribed for treating migraine.

We announced positive results
from Phase 2 clinical studies of UDB and MAP0004 in early 2007 and initiated a Phase 3 clinical program for UDB in January 2008. For our MAP0004 migraine program we received a special protocol assessment (SPA) from the FDA in January 2008, conducted
investigator meetings and initiated clinical sites. We are working on manufacturing and qualification of clinical supplies with our external commercial manufacturing partners and upon completion of this work we expect to initiate this Phase 3 trial.
We hold worldwide commercialization rights for each of our product candidates and intend to market UDB and MAP0004 in the United States through our own focused sales force targeting pediatricians for UDB and neurologists and headache specialists for
MAP0004. Our program for UDB includes Phase 3 pivotal efficacy clinical trials as well as trials of the uptake of UDB by the body, and with respect to MAP0004, our program will include Phase 3 pivotal efficacy clinical trials as well as a
pharmacokinetic trial and a trial of the effect of MAP0004 on the body.

Our product portfolio also includes two earlier stage product
candidates, both of which 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, or COPD, 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. We have no
current intention to further develop either of these earlier stage product candidates independently.

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 $117.3 million as of March 31, 2008. We have financed our operations through equity financing, debt financing and the
issuance of convertible notes. Prior to our initial public offering, or IPO, in October 2007, we had received net proceeds of $106.7 million from the issuance of convertible notes payable and convertible preferred stock. With the completion of our
initial public offering we received net proceeds of $62.1 million after expenses and underwriters discounts and commissions. In 2006, we entered into loan facility agreements and borrowed $10.0 million to finance working capital and $1.0
million to finance equipment purchases. In May 2008, we entered into an agreement to borrow $20.0 million in order to finance our product development, support general corporate purposes, and to repay the existing working capital loan entered into in
2006.

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 currently in clinical development, expand our research and development activities, seek regulatory approvals and engage in
commercialization preparation activities in anticipation of potential U.S. Food and Drug Administration, or FDA, approval of our product candidates. We will need to 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.

In connection with the IPO, we initiated a 1-for-1.77 reverse stock split effective on October 4,
2007. All shares and per share amounts have been retroactively adjusted to give effect to the reverse stock split.

Critical Accounting Policies

The accounting policies that we consider to be our most critical (those that are most important to the portrayal of our financial condition
and results of operations and that require our most difficult, subjective or complex judgments), the effects of those accounting policies applied and the judgments made in their application are summarized in
Item 7Managements Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting Policies and Estimatesin our Annual Report on Form 10-K for the fiscal year ended
December 31, 2007.

Financial Overview

Research and Development Expenses

Research and development expenses consist of: (i) milestone payments paid to
our collaborative partners who work on our processing and supply of clinical trial material; (ii) 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; (iii) the cost of manufacturing clinical trial materials; (iv) payments to contract service organizations, as well as consultants; (v) employee-related expenses, which include salaries
and benefits; (vi) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements and equipment and laboratory and
other supplies; and (vii) stock-based compensation expense. All research and development expenses are expensed as incurred.

Conducting a significant amount of research and development is central to our business model. Through March 31, 2008, we had incurred approximately $84.2 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 the clinical trials. We plan to increase our
research and development expenses for the foreseeable future in order to complete development of our two most advanced product candidates, UDB and MAP0004, and our earlier-stage research and development projects.

The following table summarizes the percentages of our research and development expenses related to our two most advanced product candidates and other
projects, including MAP0005 and MAP0001. 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, are not tracked on a project basis and are allocated based on managements estimate.

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 others, 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, the uncertainty associated with clinical trial enrollments and the 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 two most advanced product candidates. However, we will need to raise substantial additional capital in the future
in order to complete the development and commercialization of UDB and MAP0004 following the submission of new drug applications, or NDAs, and to fund the development and commercialization of our 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 and consulting fees.
We expect these expenses to increase as we continue to grow our business.

Research
and Development Expenses. The increase in research and development expenses was primarily related to an increase of $4.8 million in clinical trial expenses and $1.2 million in personnel expenses to support our Phase 3 clinical programs related
to our two lead product candidates, and $0.8 million resulting from attaining a milestone relating to our UDB program.

Sales, General
and Administrative Expenses. The increase in sales, general and administrative expenses was primarily related to increases of $0.5 million in personnel expenses, $0.3 million in share-based compensation, as well as increases in professional
services, taxes and insurance.

Interest Income. The increase in interest income was due primarily to an increase in average cash
balances increased cash, cash equivalent and short-term investment balances in the three months ended March 31, 2008 as compared to 2007, due primarily to the proceeds raised from our IPO. We expect our interest income to fluctuate in the
future with changes in average investment balances and market interest rates.

Interest Expense. Interest expense for the three
months ended March 31, 2008 and 2007 consisted of interest payments on debt. We expect our interest expense to fluctuate in the future with average debt balances.

Other Income (Expense), Net. Other income (expense), net for the three months ended March 31, 2007 primarily consisted of the change in carrying value of warrants to purchase redeemable convertible
preferred stock. At the time of our IPO, the warrants to purchase preferred stock converted into warrants to purchase common stock with the carrying value included in equity and no further expense was incurred. Other income (expense), net, for the
three months ended March 31, 2008 primarily consisted of gains of $91,000 due to the sale of investments.

Liquidity and Capital Resources

We have incurred losses since our inception in July 2003 and, as of March 31, 2008, we had an accumulated deficit of $117.3 million.
We anticipate that we will continue to incur net losses for the next several years. We expect that our research and development, and sales, general, and administrative expenses will continue to increase 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 and issuance of convertible notes. Prior to our IPO in October 2007, we had received net proceeds of $106.7 million from the issuance of convertible notes payable and convertible preferred stock. Through our IPO we received
net proceeds of $62.1 million after expenses and underwriters discounts and commissions. In 2006, we entered into loan facility agreements and borrowed $10.0 million to finance working capital and $1.0 million to finance equipment
purchases. In May 2008, we entered into an agreement to borrow $20.0 million in order to finance our product development, support general corporate purposes and to repay the existing working capital loan entered into in 2006.

As of March 31, 2008, we had $81.1 million in cash, cash equivalents and short-term investments. Our cash and short-term investment balances
are held in a variety of interest bearing instruments, including commercial paper, U.S. government agencies and money market funds. Cash in excess of immediate requirements is invested in accordance with our investment policy primarily with a view
to capital preservation and liquidity.

Net cash used in operating activities. Net cash used in operating activities primarily
reflects the net loss for those periods as we continue as a development stage company. The net loss in each period was reduced in part by non-cash depreciation and amortization, stock-based compensation and changes in operating assets and
liabilities. The increase for the three months ended March 31, 2008 as compared to the same period of 2007 was primarily driven by an increase in operating expenses related to our clinical development programs and an increase in headcount
across all departments.

Net cash used in investing activities. Net cash used in investing activities was primarily related to
purchase of investments offset in part by the proceeds from the sale of short-term investments, with more sales and maturities of investments in 2008 as compared to 2007. Purchase of property and equipment increased over the prior year period due to
our companys growth.

Net cash provided by financing activities. Net cash provided by financing activities was primarily
attributable to the issuance of Series D convertible preferred stock in the three months ended March 31, 2007. Net cash used in financing activities for both periods was attributable to repayments made on outstanding loan amounts.

Contractual Obligations

As of March 31, 2008, future minimum payments under lease obligations and debt obligations were as follows (in thousands).

|(1) | During 2006, we entered into loan facility agreements and borrowed $11.0 million for the purpose of financing working capital and purchasing equipment. The $10.0 million working
capital loan bears interest at an annual rate of 11.9% and the $1.0 million equipment loan is repayable in equal monthly payments and bears interest at an annual interest rate of 9.5%. In May 2008, we secured $20.0 million in debt financing (2008
Loan) for working capital purposes and to repay the existing working capital loan. The 2008 Loan bears interest at 9.95% and has interest-only payments until January 2009 maturing in October 2011. The amounts in the table above include interest and
principal repayments on the 2006 loans through May 1, 2008, and interest and principal payments under the 2008 Loan thereafter. Please see Note 7. Subsequent Events in the notes to the condensed consolidated financial statements in
this Form 10-Q for additional information relating to the new debt.

|(2) | On March 21, 2008, we amended our lease agreement to extend the agreement until June 2012, and to include additional square footage and options to lease additional square
footage. Please see Note 3. Commitments and Contingencies in the notes to the condensed consolidated financial statements in this Form 10-Q for additional information.

The table above reflects only payment obligations for development products that are fixed and determinable. Milestone payments and royalty payments under
our license and supply agreements are not included in the table above because we cannot, at this time, determine when or if the related milestones will be achieved or the events triggering the commencement of payment obligations will occur. Please

Recent Accounting Pronouncements

We adopted Emerging Issues Task Force (EITF) Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities, on a
prospective basis for new contracts entered into on or after January 1, 2008. EITF Issue No. 07-3 states that nonrefundable advance payments for future research and development activities should be deferred and recognized as an expense as
the goods are delivered or the related services are performed. Entities should then continue to evaluate whether they expect the goods to be delivered or services to be rendered and, if an entity does not expect the goods to be delivered or services
to be rendered, the capitalized advance payment should be charged to expense. The adoption of EITF Issue No. 07-3 did not have a material effect on our financial position or results of operations.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 157, Fair
Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for
financial statements issued for fiscal years beginning after November 15, 2007, and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2Effective Date of FASB Statement
No. 157) which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) for
fiscal years beginning after November 15, 2008. The partial adoption of SFAS 157 for financial assets and liabilities did not have a material impact on our condensed consolidated financial position, results of operations or cash flows. Please
see Note 2. Certain Balance Sheet Components in the notes to the condensed consolidated financial statements in this Form 10-Q for additional information.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159) effective for us January 1, 2008. SFAS 159 permits companies to
choose to measure certain financial instruments and other items at fair value. We chose not to elect the fair value option for financial assets and liabilities existing at January 1, 2008, and did not elect the fair value option on financial
assets and liabilities transacted in the three months ended March 31, 2008. Therefore, the adoption of SFAS 159 had no impact on our financial position or results of operations.

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 exposure to market risk is confined to our cash, cash equivalents and short-term investments which have maturities not to exceed one year. The goals of our investment policy are preservation of capital, fulfillment of liquidity needs
and capture a market rate of return based on our investment policy parameters and market conditions. We also seek to maximize income from our investments without assuming significant risk. To achieve our goals, we maintain a portfolio of cash
equivalents and investments in a variety of securities of high credit quality. The securities in our investment portfolio are not leveraged, are classified as available for sale and are, due to their very short-term nature, subject to minimal
interest rate risk. We currently do not hedge interest rate exposure. Because of the short-term maturities of our investments, we do not believe that an increase in market rates would have any material negative impact on the value of our investment
portfolio.



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

Evaluation of Disclosure Controls and
Procedures

We maintain disclosure controls and procedures and internal controls that are designed to provide reasonable assurance that information
required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and that such information is accumulated and communicated to our management,
including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures and internal controls, management
recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management
necessarily was required to apply its judgment in evaluating the cost benefit relationship of possible controls and procedures and internal controls.

Management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as required by Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as
amended. Based on this review, our Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures were effective as of March 31, 2008 at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

During the
first quarter of 2008, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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

We are not a party to any 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 in each year since our inception, including net losses of approximately $16.2 million, $25.8 million and $40.1 million, for the years ended December 31, 2005, 2006 and 2007, respectively. As of
March 31, 2008, we had a deficit accumulated during development stage of approximately $117.3 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 any product candidate and have therefore not generated any product revenues. In that regard, we expect our expenses to increase as we proceed with our Phase 3 clinical programs for our two
most advanced product candidates and conduct our 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 and we expect to continue to incur costs
to support operations as a public company. As a result, we expect to 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 (deficit) 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. In addition, our expenses could increase beyond
expectations if we are required by the FDA to perform studies in addition to those that we currently anticipate. Currently, we have no products approved for commercial sale, and to date we have not generated any product revenue. We have financed our
operations primarily through the sale of equity securities and debt financings. The size of our future net losses will depend, in part, on the rate of growth of our expenses and the rate of growth, if any, of our revenues. Revenues from potential
strategic partnerships are uncertain because we may not enter into any strategic partnerships. If we are unable to develop and commercialize one or more of our 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 or 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 two most advanced product candidates, Unit Dose Budesonide, or UDB, for pediatric asthma, and MAP0004 for migraine;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in the commencement, enrollment, and the timing of, clinical testing;
| | - |  | ----------------------------------------------------------------------------



| |  |  | our ability to manage our supply chain for study drug, other clinical materials and potentially approved products;

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

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 proceed with our Phase 3 clinical
programs and conduct our other clinical trials of our two most advanced product candidates. In addition, our expenses could increase beyond expectations if the FDA requires that we perform additional studies to those that we currently anticipate,
and the timing of any potential product approval may be delayed. We currently have no commitments or arrangements for any additional financing to fund the research and development of our product candidates. 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 based on our current spending. However, we will need to raise substantial additional capital in the future in order to
complete the development and commercialization of UDB and MAP0004 given the cost of developing and commercializing two product candidates in parallel, 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. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not
available, we may be required to delay, reduce the scope of or eliminate one or more of our 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.

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 commercial-scale outsourced manufacturing activities; and

Risks Relating to the Development, Regulatory Approval and

Commercialization of Our Product Candidates

We are largely dependent on the success of our
two most advanced product candidates, UDB and MAP0004, and we cannot be certain that either of these product candidates will receive regulatory approval.

We have invested a significant portion of our efforts and financial resources in the development of our two most advanced product candidates, UDB and MAP0004. 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 these product candidates. We may have inadequate financial or other resources to advance these product
candidates through the clinical trial process, depending on the requirements of the FDA. We have initiated a Phase 3 clinical trial for UDB. For our MAP0004 migraine program we have received a special protocol assessment (SPA) from the FDA,
conducted investigator meetings and initiated clinical sites. We are working on manufacturing and qualification of clinical supplies with our external commercial manufacturing partners and upon completion of this work we expect to initiate this
Phase 3 trial. Our clinical development programs for UDB and MAP0004 may not lead to regulatory approval from the FDA and similar foreign regulatory agencies if we fail to demonstrate that the product candidates are 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 UDB and MAP0004 would have a material and adverse impact on our business.

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. 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.

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 UDB and MAP0004 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;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | obtaining regulatory approval to commence a clinical trial;
| | - |  | -----------------------------------------------------------



| |  |  | obtaining institutional review board, or IRB, approval to conduct a clinical trial at numerous prospective sites;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including meeting the enrollment criteria for our study and
competition from other clinical trial programs for the same indication as our product candidates;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | retaining patients who have initiated a clinical trial but may be prone to withdraw due to the treatment protocol, lack of efficacy, personal issues or side effects
from the therapy or who are lost to further follow-up;

| |  |  | maintaining and supplying clinical trial material on a timely basis; and
| | - |  | ------------------------------------------------------------------------



| |  |  | complying with design protocols of any applicable SPAs.
| | - |  | -------------------------------------------------------

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; or
| | - |  | -------------------------------------------------------------------------------------------------



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

If we are
required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, particularly for our UDB and MAP0004 product candidates, we may be delayed in obtaining, or may not be able to
obtain, marketing approval for these product candidates. We have initiated a Phase 3 clinical trial for UDB and currently are enrolling patients in this trial. For our MAP0004 migraine program we have received an SPA from the FDA, conducted
investigator meetings and initiated clinical sites. We are working on manufacturing and qualification of clinical supplies with our external commercial manufacturing partners and upon completion of this work we expect to initiate this Phase 3 trial.
Our programs for UDB and MAP0004 will include Phase 3 pivotal efficacy clinical trials as well as additional trials of the uptake of UDB by the body, known as pharmacokinetic trials, and with respect to MAP0004, a pharmacokinetic trial and a trial
of the effect of MAP0004 on the body, known as a pharmacodynamic trial. Furthermore, we may not be able to obtain approval for indications that are as broad as intended or entirely different than those indications for which we sought approval.

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 earlier clinical trials
are not necessarily predictive of future results, UDB, MAP0004 or any other product candidate we advance into clinical trials may not have favorable results in later clinical trials or receive regulatory approval.

Success in pre-clinical studies and early clinical trials does not ensure that later clinical trials will generate adequate data to demonstrate the
efficacy and safety of the investigational drug. A number of companies in the pharmaceutical industry, including those with greater resources and experience, have suffered significant setbacks in Phase 3 clinical trials, even after seeing
promising results in earlier clinical trials.

We initiated a Phase 3 clinical program for UDB in January 2008. For our MAP0004 migraine
program we have received an SPA from the FDA, conducted investigator meetings and initiated clinical sites. We are working on manufacturing and qualification of clinical supplies with our external commercial manufacturing partners and upon
completion of this work we expect to initiate this Phase 3 trial. We anticipate conducting additional Phase 2 clinical studies for UDB and MAP0004. Specifically, we intend to conduct two pharmacokinetic trials for UDB and a pharmacokinetic trial and
a separate pharmacodynamic trial for MAP0004. The data collected from our clinical trials may not be adequate to support regulatory approval of UDB, MAP0004 or any of our other product candidates. Despite the results reported in earlier clinical
trials for our product candidates, we do not know whether any Phase 3 or other clinical programs we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market our product

candidates. For instance, the Phase 2 clinical trial of UDB compared two doses of UDB, at 0.135 mg and 0.25 mg administered twice a day. The study showed
that 0.135 mg of UDB produced a statistically significant reduction in Nighttime and Daytime Composite Symptom Score, a measure of asthma severity, when compared to placebo, but the 0.25 mg dose was not significantly better than placebo in Nighttime
and Daytime Composite Symptom Score. In our Phase 3 clinical trial for UDB, patients will be randomized and given 0.25 mg UDB, 0.135 mg UDB or placebo to evaluate changes in Nighttime and Daytime Composite Symptom Score. We may not demonstrate
statistically significant efficacy for the 0.25 mg dose or the 0.135 mg dose, which could make it difficult to receive regulatory approval for either dose.

If clinical trials of our UDB or MAP0004 product candidates 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 UDB, MAP0004 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, and we may decide, or regulators may require us, to conduct additional clinical and/or non-clinical testing. 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 the denial of 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 UDB, MAP0004 or any other product candidates would prevent regulatory approval and, ultimately, the commercialization of that product candidate. For example, the Phase 2
clinical trial of UDB compared two doses of UDB, at 0.135 mg and 0.25 mg administered twice a day. The study showed that 0.135 mg of UDB produced a statistically significant reduction in Nighttime and Daytime Composite Symptom Score when compared
with placebo, but the 0.25 mg dose was not significantly better than placebo in Nighttime and Daytime Composite Symptom Score. In our Phase 3 clinical trial for UDB, patients will be randomized and given 0.25 mg UDB, 0.135 mg UDB or placebo to
evaluate changes in Nighttime and Daytime Composite Symptom Score. If we are unable to show a statistically significant reduction in Nighttime and Daytime Composite Symptom Score at the 0.25 mg dose, we may only obtain approval for our UDB product
candidate at the single 0.135 mg dose, thereby potentially limiting our sales opportunities.

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 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 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 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 a SPA with
the FDA for our first Phase 3 clinical trial of MAP0004 for the potential treatment of migraine, the achievement of pre-specified trial results under 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 pre-specified trial results are achieved, they may serve as the primary basis for an
efficacy claim in support of a 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 MAP0004 product candidate for the potential treatment of migraine. We cannot assure you that 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 MAP0004 product candidate for the treatment of migraine. As a result, we cannot guarantee any
particular outcome from regulatory review of the first MAP0004 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 Federal Food, Drug and Cosmetic Act, or 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 receive regulatory approval do not achieve broad market acceptance, the revenues that we generate from their sales will
be limited.

The commercial success of our product candidates for which we obtain marketing approval from the FDA or other regulatory
authorities will depend upon the acceptance of these products 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:



| |  |  | limitations or warnings contained in a products FDA-approved 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 clinical safety and efficacy compared to other products;
| | - |  | ---------------------------------------------------------------------------



| |  |  | 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 at similar or lower costs;
| | - |  | ----------------------------------------------------------------



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



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

Our ability to effectively promote and sell our product candidates in the marketplace will also depend on pricing and cost effectiveness, including our 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. Market acceptance could be further limited depending on the prevalence and severity of any expected or unexpected
adverse side effects associated with our product candidates. If our product candidates are approved but do not achieve an adequate level of acceptance by physicians, health care payors and patients, we may not

generate sufficient revenue from these products, and we may not become or remain profitable. In addition, our efforts to educate the medical community and
third-party payors on the benefits of our product candidates may require significant resources and may never be successful. 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. In order to commercialize our most advanced product candidates, we intend to develop a focused sales
force and marketing capabilities in the United States. 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. These costs may 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 pediatrics and neurology. If we are unable to establish our focused sales force and marketing capability for our most
advanced product candidates, 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 pediatric asthma market is extremely competitive which may adversely affect our ability to commercialize UDB.

If approved for the treatment of pediatric asthma, we anticipate that UDB would compete with other marketed asthma therapeutics, including inhaled
corticosteroids and leukotriene antagonists, and may compete with products currently under development by both large and small companies. Conventional nebulized budesonide is the only inhaled corticosteroid approved by the FDA for treating asthma in
children under four years old and is available from AstraZeneca plc as Pulmicort Respules. Pulmicort Respules was introduced in the United States in 2000, and annual sales have grown to approximately $880 million in the United States and
approximately $1.1 billion worldwide in 2007 according to data published by IMS Health. Leukotriene antagonists are an alternative to inhaled corticosteroids for asthmatic children. Prescriptions of Singulair, the leading leukotriene antagonist, for
children under the age of six generated approximately $500 million in sales in 2007. In addition to the marketed asthma therapies, there are several inhaled corticosteroid product candidates under development by large pharmaceutical companies, such
as GlaxoSmithKline plc, or GlaxoSmithKline, and other smaller companies, that could potentially be used to treat pediatric asthma.

We may
also face competition from potential generic entry of conventional nebulized budesonide. For example, Teva Pharmaceuticals Industries Ltd. has filed a generic or abbreviated new drug application, or ANDA, for conventional nebulized budesonide based
on Pulmicort Respules. Although we believe a generic product could not be substituted for UDB, if approved, a generic version of conventional nebulized budesonide may be more quickly adopted by health insurers and patients than UDB. Financial
pressure to use generic products and uncertainty of reimbursement for single source alternatives, such as UDB, may encourage the use of a generic product over UDB.

The migraine market is extremely competitive which may negatively impact the commercialization of MAP0004.

If approved for the treatment of acute migraine, we anticipate that MAP0004 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
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 which may have faster onset of action than solid oral dosage forms. Alternative formulations of DHE include Migranal, which is nasally delivered. In addition to the marketed migraine therapeutics,
there are several product candidates under development by large pharmaceutical companies, such as GlaxoSmithKline and Merck & Co., Inc., and other smaller companies, that could potentially be used to treat migraines and compete with
MAP0004.

In addition, we may face competition from generic sumatriptan, the active ingredient in Imitrex. Although we believe generic
sumatriptan could not be substituted for MAP0004, if approved, a generic version of sumatriptan may be more quickly adopted by health insurers and patients than MAP0004. Financial pressure to use generic products and uncertainty of
reimbursement for single source alternatives, such as MAP0004, may encourage the use of a generic product over MAP0004.

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, 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. 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 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 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 others. Failure to obtain regulatory approval in
other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the 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 either or both of our most advanced product candidates 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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | 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 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. 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 UDB, MAP0004 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 MAP0004 labeling to carry this
contraindication.

Our product candidates will also be subject to ongoing FDA requirements for the labeling, packaging, storage,
advertising, promotion, record-keeping and submission of safety and other post-market information on the drug. In addition, approved products, manufacturers and manufacturers facilities are subject to continual review and periodic inspections.
If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose restrictions
on that product or us, including requiring withdrawal of the product from the market. If our product candidates fail to comply with applicable regulatory requirements, such as current Good Manufacturing Practices, or cGMPs, a regulatory agency may:



| |  |  | issue warning letters;
| | - |  | ----------------------



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



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



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



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



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



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



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

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

Any name we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a formal trademark
registration from the U.S. Patent and Trademark Office. The FDA typically conducts a rigorous review of proposed product names, including an evaluation of 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 initial product candidates. If we adopt an alternative name, we 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 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. For example, organizations like Global Initiative for Asthma, or GINA, and the National Asthma Education and Prevention Program, or NAEPP,
have made recommendations about therapies in the pediatric asthma market. GINA guidelines issued in 2006 and NAEPP guidelines issued in 2007 recommend the use of inhaled corticosteroids as the preferred treatment to reduce inflammation and maintain
long-term control of asthma in children aged five years and younger. 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 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 many 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 who 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 and quality assurance;
| | - |  | ------------------------------------------------------------------------------



| |  |  | 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 our products 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 MAP0004 to primary care physicians, 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 all of our product candidates in order to effectively reach target markets in order to maximize their commercial opportunities.
We also expect to face competition in our efforts to identify appropriate collaborators or partners to help commercialize our product candidates 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 these product candidates.

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

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 collaborators. 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 collaborators to help develop MAP0005 and MAP0001, but are unable to reach agreements with suitable
collaborators, 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 or third-party patents. 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 compounds 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 pending issued patents or patent applications;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



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



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



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



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



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



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

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

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

If we 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

##### Table of Contents

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

As of March 31, 2008, we had 79 full-time employees. We will need to continue to expand our managerial, operational, financial and other
resources in order to manage and fund our operations and clinical trials, continue our development activities and commercialize our product candidates. To support this growth, we expect to 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 programs and other additional trials effectively, which we anticipate will be conducted 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 the intense 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.

##### Table of Contents

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.

Our executive officers and certain key personnel are critical to our business
and have limited experience in running a public company and are new to their current roles.

As a public company, we are highly
dependent on the expertise of our senior management, particularly our Chief Executive Officer and Chief Financial Officer. Many members of our senior management have not previously acted in their current capacities for a public company. In addition,
certain key members of our management team were hired recently. Therefore, they will not have been involved with our business and have not worked together as a team for a significant period of time. Consequently, their focus and attention may be
diverted while they familiarize themselves with our business.

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 76% 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;
| | - |  | -----------------------------------------------------------------------------



| |  |  | 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 product or new products that may emerge;
| | - |  | ------------------------------------------------------------------



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

Furthermore, the stock markets have experienced extreme price and volume fluctuations that have affected
and continue to affect the market prices of equity securities of many companies. These fluctuations 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 the market price of shares of our common
stock decline in value, stockholders may lose some or all of their investment. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target
of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our managements attention from other business concerns, which could seriously harm our business.

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 initial public offering 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 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 Securities 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 that we did not incur as a private company. For example, we must use additional 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 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 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 pharmaceutical companies. These broad market fluctuations may cause the market price of our
common stock to decline. In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and
biopharmaceutical companies have experienced significant stock price volatility in recent years. We may become involved in this type of litigation in the future. Litigation often is expensive and diverts managements attention and resources,
which could adversely affect our business.
