The 2015 Stock Plan replaced the 2006 Stock Plan which was terminated upon adoption of the 2015 Stock Plan. Shares of common stock reserved for outstanding awards under the 2006 Stock Plan that lapse or are canceled will be added back to the share reserve available for future awards under the 2015 Stock Plan. The 2015 Stock Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock and other stock-based compensation awards to employees, officers, directors and consultants of the Company. The administration of the 2015 Stock Plan is under the general supervision of the compensation committee of the board of directors. The exercise price of the stock options is determined by the compensation committee of the board of directors, provided that incentive stock options are granted with an exercise price not less than fair market value of the common stock on the date of grant and expire no later than ten years from the date the option is granted. Options generally vest over four years. As of June 30, 2016, the Company had options outstanding to purchase 5,277,864 shares of its common stock, which includes options outstanding under its 2001 Stock Plan and 2006 Stock Plan that were terminated in March 2006 and June 2015, respectively. As of June 30, 2016, 12,695,764 shares were available for future issuance.   The following table summarizes stock option activity during the six months ended June 30, 2016:   <div

the Compensation Committee approved the grant of five million milestone-based restricted stock units (RSU’s), effective on January 4, 2016, to certain executive officers and non-executive employees. The restricted stock units only vest if the executive officer or non-executive employee is employed by the Company at the closing of a defined Transaction that occurs on or prior to December 31, 2016, or if such person is terminated prior to that date by the Company other than for cause. The grant was intended to further align the interests of the Company’s executive team with its stockholders by providing equity participation in a strategic transaction and to promote maximizing stockholder value in such a transaction. If completed, the Proposed Merger with Madrigal would be a covered Transaction. The Company will not recognize stock compensation in connection with these restricted stock units until the closing of the Proposed Merger with Madrigal Pharmaceuticals, Inc. (see Note 10), which is expected to occur in the third quarter of 2016, subject to customary closing conditions, including the approval of the Company’s stockholders and the Company having a minimum net cash amount of $28.5 million.   Stock-Based Compensation Expense   For the three months and six months ended June 30, 2016 and 2015, the fair value of each employee stock option award was estimated on the date of grant based on the fair value method using the Black-Scholes option pricing valuation model with the following weighted average assumptions:   <div style="width:100%;"><table

This ASU supersedes the revenue recognition requirements in ASC Topic 605, and creates a new Topic 606, Revenue from Contracts with Customers . This guidance was originally effective for fiscal years beginning after December 15, 2016, with early adoption not permitted. Two adoption methods are permitted: retrospectively to all prior reporting periods presented, with certain practical expedients permitted; or retrospectively with the cumulative effect of initially adopting the ASU recognized at the date of initial application. The FASB approved a one year deferral of the effective date of this standard to annual periods beginning after December 15, 2017, along with an option to permit companies to early adopt the standard for annual periods beginning after December 15, 2016. The Company has not yet determined the date it plans to adopt ASU No. 2014-09, which adoption method it will utilize, or the effect that the adoption of this guidance will have on its consolidated financial statements.   In June 2014, the FASB issued ASU No. 2014-12, —Compensation—Stock Compensation (Topic 718), Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . ASU No. 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this update apply prospectively to all share-based payment awards that are granted or modified on or after the effective date, or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the consolidated financial statements, and to all new or modified awards thereafter. ASU No. 2014-12 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2015. The Company adopted ASU No. 2014-12 effective January 1, 2016 and is applying this standard to account for restricted stock units granted to certain executive officers and non-executive employees (See Note 5).   In August 2014, the FASB issued ASU No. 2014-15, —Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements and to provide related footnote disclosures. This guidance is effective for fiscal years ending after December 15, 2016, with early application permitted. If this standard had been adopted as of June 30, 2016, the Company believes that it would have concluded there was not substantial doubt about its ability to continue as a going concern. However, the Company faces risks and uncertainties, as further described in Note 1, Nature of Business¸ that would have been considered in this analysis. The adoption of this guidance may have an effect on the Company’s disclosures in future periods.   In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The new standard will be effective for the Company on January 1, 2019. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements.   In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation, which amends ASC Topic 718, Compensation — Stock Compensation. The new standard identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The amendments are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is currently evaluating the potential impact that ASU 2016-09 may have on the Company’s financial position or results of operations. </div><div style="margin-left:0%;margin-right:0%;"> </div><div style="margin-left:0%;margin-right:0%;"></div> </div>

<div> <div style="margin-left:0%;margin-right:0%;"></div><div style="margin-left:0%;margin-right:0%;"> Revenue Recognition   Collaboration and License Agreements   The Company’s principal source of revenue to date has been its former collaboration and license agreements, which included upfront license payments, development milestones, reimbursement of research and development costs, potential profit sharing payments, commercial and sales-based milestones and royalties. The accounting for collaboration and license agreements requires subjective analysis and requires management to make estimates and assumptions about whether deliverables within multiple-element arrangements are separable from the other aspects of the contractual arrangement into separate units of accounting and to determine the arrangement consideration to be allocated to each unit of accounting.   For multiple-element arrangements entered into or materially modified after January 1, 2011, the Company follows the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2009-13— Multiple-deliverable Revenue Arrangements (ASU No. 2009-13). ASU No. 2009-13 amended certain provisions of Accounting Standards Codification (ASC) Topic 605— Revenue Recognition . This standard addresses the determination of the unit(s) of accounting for multiple-element arrangements and how an arrangement’s consideration should be allocated to each unit of accounting.   Pursuant to this standard, each required deliverable is evaluated to determine if it qualifies as a separate unit of accounting. For the Company this determination includes an assessment as to whether the deliverable has “stand-alone value” to the customer separate from the undelivered elements. The arrangement’s consideration is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i) vendor-specific objective evidence of fair value, (ii) third-party evidence of selling price, or (iii) the Company’s best estimate of the selling price (BESP). The BESP reflects the Company’s best estimate of what the selling price would be if the deliverable was regularly sold by it on a stand-alone basis. The Company expects, in general, to use BESP for allocating consideration to each deliverable in future collaboration agreements. In general, the consideration allocated to each unit of accounting is then recognized as the related goods or services are delivered limited to the consideration not contingent upon future deliverables. The Company did not recognize any revenue related to collaboration and license agreements during the three months and six months ended June 30, 2016 and 2015.   The Company accounts for development milestones under collaboration and license agreements pursuant to ASU No. 2010-17 Milestone Method of Revenue Recognition (ASU No. 2010-17). ASU No. 2010-17 codified a method of revenue recognition that has been common practice. Under this method, contingent consideration from research and development activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether each milestone is substantive. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, or (2) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone, (b) the consideration relates solely to past performance and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment. The Company does not have any ongoing collaboration and license agreements under which milestones may be achieved.   Royalty revenues are based upon a percentage of net sales. Royalties from the sales of products will be recorded on the accrual basis when results are reliably measurable, collectability is reasonably assured and all other revenue recognition criteria are met.
