<div> 2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Our significant accounting policies and recent accounting pronouncements were described in Note 2 to our Consolidated Financial Statements included in our 2013 Annual Report on Form 10-K for the fiscal year ended December 31, 2013. There have been no significant changes in our accounting policies since December 31, 2013. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. The financial statements include all adjustments (consisting only of normal recurring adjustments) that we believe are necessary for a fair presentation of the periods presented. The condensed consolidated balance sheet at December 31, 2013 was derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. These interim financial results are not necessarily indicative of results to be expected for the full fiscal year or any other future period and should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2013, included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission, or SEC. Revenue Recognition Revenue is generated from product sales and recorded net of mandatory government rebates. We only ship product upon receipt of valid orders from customers, such as pharmacies and hospitals, which are in turn a result of actual patient prescriptions. Delivery is considered to have occurred when title passes to a credit-worthy customer. We include shipping and handling costs in cost of goods sold. Pursuant to terms and conditions of sale, our customers have no general right of product return but we permit returns if the product is damaged or defective when received by the customer. Such restriction on product returns is common practice in the markets in which we sell, and as a result, we have had no significant expenses related to product returns, damaged or expired goods. To date, all significant amounts recorded as estimates of items that reduce gross revenue related solely to mandatory government rebates, many of which were negotiated on a confidential basis with the respective government reimbursement agencies. Our estimation of these rebates requires only the application of pre-specified rates, determined as part of pre-launch pricing negotiations with the relevant government reimbursement agencies, to sales of our product as applicable. We recognize these mandatory government rebates as reductions of product sales and the recording of these rebates is substantially mechanical in nature and does not involve the application of significant judgment. Fluctuations in the amounts recorded for these rebates relate solely to increased sales or the eventual payment of amounts due to the various government agencies. To date, we have had no significant charges or credits related to prior period estimates. Derivative Financial Instruments On January 22, 2013, we issued $120.8 million aggregate principal amount of 2.50% convertible senior notes due 2017 (the “2017 Notes”). As a result of our issuance of the 2017 Notes, our total potential outstanding common stock exceeded our authorized shares by approximately 4.3 million shares as of that date and we were therefore required to value the embedded conversion derivative and recognize it at fair value as a long-term liability. On May 30, 2013, we obtained stockholder approval to an amendment to our certificate of incorporation to increase the number of our authorized shares of common stock from 100,000,000 to 175,000,000. As a result of the increase in authorized number of shares, we can now settle the 2017 Notes in cash, stock, or a combination thereof, solely at our election, the derivative associated with the embedded conversion derivative was marked to fair value at May 30, 2013 and the long-term liability was reclassified to stockholders’ equity. See also Note 10 for further details of our embedded conversion derivative. Net Income (Loss) Per Share Basic net loss per share is calculated based on the weighted-average number of shares of our common stock outstanding during the period, as adjusted. Diluted net loss per share is calculated based on the weighted average number of shares of our common and other dilutive securities outstanding during the period. The potential dilutive shares of our common stock resulting from the assumed exercise of outstanding stock options and shares subject to repurchase are determined under the treasury stock method. The potential dilutive shares of our common stock issuable on conversion of our convertible notes are determined using the “if-converted” method. Anti-dilutive securities, which consist of stock options, restricted stock awards and units, and shares that could be issued upon conversion of our convertible notes, are not included in the diluted net loss per share calculation. For the calculation of net loss per share, anti-dilutive securities excluded were as follows:   <div> <table border="0" cellspacing="0" cellpadding="0" align="center"

Compensation, stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the vesting period for that portion of the award that is ultimately expected to vest. In order to estimate the value of share-based awards, we use the Black-Scholes model, which requires the use of certain subjective assumptions. The most significant assumptions are our estimates of the expected volatility, the expected term of the award and the estimated forfeiture rate. Segment ReportingWe have determined, in accordance with ASC 280, Segment Reporting, that our business operates in one operating segment: the research, development and commercialization of innovative therapies in pulmonology and orphan fibrotic diseases.</div>

<div> 5.   FAIR VALUE In accordance with ASC 820-10, Fair Value Measurements and Disclosures, we determine the fair value of financial and non-financial assets and liabilities using the fair value hierarchy, which establishes three levels of inputs that may be used to measure fair value, as follows: <div align="left"><table border="0" cellspacing="0" cellpadding="0" style="border-collapse:collapse; width:97.33%;margin-left:2.67%;"><tr><td valign="top" style="width:4.4%;white-space:nowrap"></td><td valign="top" style="width:95.6%;">Level 1 inputs which include quoted prices in active markets for identical assets or liabilities; </td></tr></table></div><div align="left"><table border="0" cellspacing="0" cellpadding="0" style="border-collapse:collapse; width:97.33%;margin-left:2.67%;"><tr><td valign="top" style="width:4.4%;white-space:nowrap"></td><td valign="top" style="width:95.6%;">Level 2 inputs which include observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. For our available-for-sale securities, we review trading activity and pricing as of the measurement date. For our convertible senior notes we determined the fair value based on quoted market values. When sufficient quoted pricing for identical securities is not available, we use market pricing and other observable market inputs for similar securities obtained from various third-party data providers. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data; and </td></tr></table></div><div align="left"><table border="0" cellspacing="0" cellpadding="0" style="border-collapse:collapse; width:97.33%;margin-left:2.67%;"><tr><td valign="top" style="width:4.4%;white-space:nowrap"></td><td valign="top" style="width:95.6%;">Level 3 inputs which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability.

securities by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate the fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data, and other observable inputs. Our foreign currency derivatives contracts have maturities less than three months and all are with counterparties that have a minimum credit rating of A or equivalent by Standard & Poor’s, Moody’s Investors Service, Inc. or Fitch, Inc. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that utilizes an income-based industry standard valuation model for which all significant inputs are observable, either directly or indirectly. These inputs include foreign currency rates, London Interbank Offered rates (LIBOR) and swap rates. These inputs, where applicable, are at commonly quoted intervals.

<div> Net Income (Loss) Per Share Basic net loss per share is calculated based on the weighted-average number of shares of our common stock outstanding during the period, as adjusted. Diluted net loss per share is calculated based on the weighted average number of shares of our common and other dilutive securities outstanding during the period. The potential dilutive shares of our common stock resulting from the assumed exercise of outstanding stock options and shares subject to repurchase are determined under the treasury stock method. The potential dilutive shares of our common stock issuable on conversion of our convertible notes are determined using the “if-converted” method. Anti-dilutive securities, which consist of stock options, restricted stock awards and units, and shares that could be issued upon conversion of our convertible notes, are not included in the diluted net loss per share calculation. For the calculation of net loss per share, anti-dilutive securities excluded were as follows:   <div> <table border="0" cellspacing="0" cellpadding="0" align="center"
