<div> 2.Liquidity The Company has a history of losses from operations and anticipates that it will continue to incur losses for at least the next several years. For the six months ended June 30, 2018, the Company incurred a net loss of $11.2 million. At June 30, 2018, the Company had an accumulated deficit of approximately $23.5 million and had cash and cash equivalents of approximately $12.4 million. The Company also had negative cash flow from operations of approximately $4.8 million during the six months ended June 30, 2018. On January 4, 2018, the Company entered into an at-the-market, or ATM, sales agreement, under which the Company may sell stock from time to time up to an aggregate of $10.0 million in gross proceeds. During January and February 2018, the Company generated gross proceeds of approximately $1.1 million, resulting in net proceeds of approximately $803,000 on sales of 375,000 shares of common stock under this agreement. In February 2018, the Company also generated gross proceeds of approximately $10.3 million, resulting in net proceeds of $9.4 million from an underwritten offering of 5.0 million shares of common stock and warrants to purchase up to 3.5 million shares of common stock. All of the financing transactions completed during the first quarter of 2018 were registered pursuant to the Company’s effective shelf registration statement on Form S-3 and the related base prospectus included in that registration statement, as supplemented by the prospectus supplements dated January 4, 2018 and February 14, 2018. The Company will need to raise additional capital to further fund the development of, and seek regulatory approvals for, its current product candidates and any future candidates it may license or otherwise acquire, as well as to commercialize any products, if approved. If additional funding is not available on a timely basis, on terms favorable to the Company and its stockholders, or at adequate levels, the Company will need to reevaluate its operating plans. The interim consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company is currently focused primarily on the development and commercialization of innovative products in women’s reproductive health and believes such activities will result in the Company’s continued incurrence of significant research and development and other expenses related to these programs. If the clinical trials for any of the Company’s product candidates fail to produce successful results such that those product candidates do not advance in clinical development, then the Company’s business and prospects may suffer. Even if the product candidates advance in clinical development, they may fail to gain regulatory approval. Even if the product candidates are approved, they may fail to achieve market acceptance, and the Company may never become profitable. Even if the Company becomes profitable, it may not be able to sustain profitability. The Company intends to cover its future operating expenses through cash and cash equivalents on hand and through a combination of equity offerings, debt financings, government or other grant funding, collaborations and strategic alliances. The Company cannot be sure that additional financing will be available when needed or that, if available, it will be obtained on terms favorable to the Company or its stockholders. As of the date of this report and based on current business plan estimates, the Company believes it has sufficient cash to fund its operating expenses over at least the next twelve months from issuance of these condensed consolidated financial statements.  In the event the Company acquires, licenses or develops any new products or product candidates that are not contemplated in its current business plan, or if the clinical development plans for its existing product candidates materially change, then the amount required to fund future operations could increase, possibly materially. In order to acquire or develop additional products and product candidates, the Company will require additional capital over time. The Company expects that its net losses will continue for at least the next several years as it seeks to acquire, license or develop additional products and product candidates. Such losses may fluctuate, the fluctuations may be substantial, and the Company may never become profitable.</div>

<div> 3. Significant Accounting Policies The Company’s significant accounting policies are described in Note 1 to the interim consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission, or SEC on March 28, 2018. Since the date of those financial statements, there have been no material changes to the Company’s significant accounting policies. Basis of Presentation The accompanying interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, as defined by the Financial Accounting Standards Board, or FASB, for interim financial information and the instructions to Form 10-Q and Article 8 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In management’s opinion, the accompanying interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the results of the interim periods presented. Interim financial results are not necessarily indicative of results anticipated for any other interim period or for the full year. The accompanying interim consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Reverse Stock Split <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">On July 20, 2017, the Company effected a 1-for-10 reverse stock split of its common stock. All share and per share amounts of common stock, options and warrants in these notes and those amounts included in the accompanying interim consolidated financial statements, have been restated for all periods to give retroactive effect to the reverse stock split. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the fair value of stock-based compensation, goodwill impairment and purchase accounting. Actual results could differ from those estimates and could materially affect the reported amounts of assets, liabilities and future operating results. Principles of Consolidation The interim consolidated financial statements of the Company are stated in U.S. dollars and are prepared using GAAP. These financial statements include the accounts of the Company and its wholly owned subsidiaries, Daré Bioscience Operations, Inc., Daré Bioscience Australia Pty LTD, and Pear Tree Pharmaceuticals, Inc. The financial statements of the Company’s wholly owned subsidiaries are recorded in their functional currency and translated into the reporting currency. The cumulative effect of changes in exchange rates between the foreign entity’s functional currency and the reporting currency is reported in accumulated other comprehensive loss in the interim consolidated balance sheets. All significant intercompany transactions and accounts have been eliminated in consolidation. Recent Pronouncements Not Yet Adopted In February 2016, FASB issued ASU 2016-02, Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The new standard is effective for public companies for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently assessing the potential impact of this accounting standard and the effect it might have on its financial statements. Recently Adopted Accounting Standards In May 2014, FASB issued Accounting Standards Update, or ASU, 2014-09, Revenue from Contracts with Customers, which impacts the way in which some entities recognize revenue for certain types of transactions. The new standard became effective beginning in 2018 for public companies. Because the Company does not currently have any contracts with customers, the Company’s adoption of this accounting standard did not impact the Company. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which intended to add or clarify guidance on the classification of certain cash receipts and payments on the statement of cash flows. The new guidance addresses cash flows related to the following: debt prepayment or extinguishment costs, settlement of zero-coupon bonds, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies and bank-owned life insurance policies, distributions received from equity method investees, beneficial interest in securitization transactions, and the application of predominance principle to separately identifiable cash flows. The standard became effective on January 1, 2018. The Company’s adoption of this standard on January 1, 2018 did not have a material impact on the Company’s interim consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In January 2017, FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which intended to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard became effective for the Company on January 1, 2018. The Company’s early adoption of this standard did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company’s adoption of this standard on September 30, 2017 did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In May 2017, FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, which intended to provide clarity when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The standard became effective for the Company on January 1, 2018. The Company’s adoption of this standard did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In July 2017, FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815): (I) Accounting for Certain Financial Instruments with Down Round Features, (II) Replacement for the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. This update was issued to provide additional clarity related to accounting for certain financial instruments that have characteristics of both liabilities and equity. In particular, this update addresses freestanding and embedded financial instruments with down round features and whether they should be treated as a liability or equity instrument. Part II simply replaces the indefinite deferral for certain mandatorily redeemable non-controlling interests and mandatorily redeemable financial instruments of nonpublic entities contained within the ASC Topic 480 with a scope exception and does not impact the accounting for these mandatorily redeemable instruments. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company has early adopted ASU 2017-11. As a result, the Company has not recognized the fair value of the warrants containing down round features that were issued in the underwritten offering in February 2018 (see Note 7) as liabilities. Fair Value Measurements U.S. generally accepted accounting principles define fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows: <div align="left"> <table border="0" cellspacing="0" cellpadding="0" style="border-collapse:collapse; width:100%;"> <tr> <td valign="top" style="width:5.24%;white-space:nowrap">  </td> <td valign="top" style="width:5.24%;white-space:nowrap"> •</td> <td valign="top"> Level 1: inputs are unadjusted 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:100%;"> <tr> <td valign="top" style="width:5.24%;white-space:nowrap">  </td> <td valign="top" style="width:5.24%;white-space:nowrap"> •</td> <td valign="top"> Level 2: inputs other than level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and 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 assets or liabilities.</td></tr></table></div> <div align="left"> <table border="0" cellspacing="0" cellpadding="0" style="border-collapse:collapse; width:100%;"> <tr> <td valign="top" style="width:5.24%;white-space:nowrap">  </td> <td valign="top" style="width:5.24%;white-space:nowrap"> •</td> <td valign="top"> Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.</td></tr></table></div> Cash and cash equivalents of $12.4 million and $7.6 million measured at fair value as of June 30, 2018 and December 31, 2017, respectively, are classified within Level 1 of the fair value hierarchy. Other receivables are financial assets with carrying values that approximate fair value due to the short-term nature of these assets. Accounts payable and accrued expenses and other liabilities are financial liabilities with carrying values that approximate fair value due to the short-term nature of these liabilities.</div>

<div> 4. Acquisitions Cerulean/Private Dare Stock Purchase Transaction As further discussed in Note 1, on July 19, 2017, the Cerulean/Private Daré stock purchase transaction closed. The Cerulean/Private Daré stock purchase transaction was accounted for as a reverse merger under the acquisition method of accounting whereby Private Daré was considered to have acquired Cerulean for financial reporting purposes because immediately upon completion of the transaction, Private Daré stockholders held a majority of the voting interest of the combined company. Pursuant to business combination accounting, the Company applied the acquisition method, which requires the assets acquired and liabilities assumed be recorded at fair value with limited exceptions. The excess of the purchase price over the assets acquired and liabilities assumed represents goodwill. The goodwill is primarily attributable to the cash and cash equivalents at closing of the transaction of approximately $9.9 million and the impact of the unamortized fair value of stock options that were granted by Cerulean and outstanding prior to the closing of the transaction of approximately $3.7 million. The unamortized fair value of such stock options relates to an option modification approved on March 19, 2017 that provided for an acceleration of vesting of such options upon a change in control event. Such modification became effective upon the closing of the Cerulean/Private Daré stock purchase transaction. Hence, the unamortized fair value of such stock options is deemed to be part of total purchase consideration and goodwill. Transaction costs associated with the Cerulean/Private Daré stock purchase transaction of $0.96 million are included in general and administrative expense. The total purchase price consideration of approximately $24.3 million represents the fair value of the shares of Cerulean stock issued in connection with the Cerulean/Private Daré stock purchase transaction and the unamortized fair value of the stock options that were granted by Cerulean and outstanding prior to the closing of the transaction that were assumed on July 19, 2017 in connection with the closing of the transaction, which was allocated as follows:   <div> <table border="0" cellspacing="0" cellpadding="0" align="center" style="border-collapse:collapse;

The Company retrospectively recorded purchase price adjustments at the acquisition date to increase current liabilities by $23,609 and increase current assets by $225,778, resulting in a $202,169 reduction to the original goodwill amount of approximately $12.9 million. The Company tests its goodwill for impairment at least annually as of December 31 and between annual tests if it becomes aware of an event or change in circumstance that would indicate the carrying value may be impaired. The Company tested goodwill for impairment at the entity level because it operates on the basis of a single reporting unit. A goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. When impaired, the carrying value of goodwill is written down to fair value. Any excess of the reporting unit goodwill carrying value over the fair value is recognized as impairment loss. The Company assessed goodwill at December 31, 2017, determined there was an impairment and recognized an impairment charge of approximately $7.5 million in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2017. Further, it reduced the carrying value of goodwill from approximately $12.7 million to $5.2 million on its consolidated balance sheet as of December 31, 2017. The Company assessed goodwill at March 31, 2018, determined that there was an impairment and recognized an impairment charge of approximately $5.2 million in the interim consolidated statement of operations and comprehensive loss for the three months ended March 31, 2018. As of March 31, 2018, the carrying value of goodwill on the Company’s consolidated balance sheet was written off in its entirety. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:10pt;margin-bottom:0pt;text-indent:7.69%;font-weight:bold;font-style:italic;font-size:10pt;font-family:Arial;text-transform:none;font-variant: normal;">Pear Tree Merger On April 30, 2018, the Company entered into an Agreement and Plan of Merger, the Merger Agreement, with Pear Tree Pharmaceuticals, Inc., or Pear Tree, Daré Merger Sub, Inc., a wholly-owned subsidiary of the Company, or Merger Sub, and two individuals in their respective capacities as Pear Tree stockholders’ representatives. The transactions contemplated by the Merger Agreement closed on May 16, 2018, and as a result, Pear Tree became the Company’s wholly owned subsidiary. The Company acquired Pear Tree to secure the rights to develop PT-101, a proprietary vaginal formulation of tamoxifen, as a potential treatment for vulvar and vaginal atrophy. The Company determined that the acquisition of Pear Tree should be accounted for as an asset acquisition instead of a business combination since substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, and therefore, the asset is not considered a business. Under the Merger Agreement, upon the closing of the merger, if the Positive Consideration Amount (as defined below) exceeded the Negative Consideration Amount (as defined below), certain former and continuing Pear Tree service providers and former holders of Pear Tree’s capital stock, or the Holders, would have been entitled to receive an amount of cash equal to such excess, and if the Negative Consideration Amount exceeded the Positive Consideration Amount, then the Company would be able to offset such excess from future payments that would otherwise be due to the Holders, including the potential payment of $75,000 due on the one-year anniversary of the closing of the merger. The Negative Consideration Amount exceeded the Positive Consideration Amount by approximately $132,000 at the time of the closing of the merger. As such, approximately $132,000 will be offset from future payments that would otherwise be due to the Holders. Under the Merger Agreement, Positive Consideration Amount means the sum of $75,000, and the cash and cash equivalents held by Pear Tree at closing, and Negative Consideration Amount means the sum of (i) certain Pear Tree indebtedness and transaction expenses, (ii) transaction expenses of the stockholders’ representatives, and (iii) amounts payable under Pear Tree’s management incentive plan. Under the Merger Agreement, the Holders will be eligible to receive, subject to certain offsets, tiered royalties, including customary provisions permitting royalty reductions and offset, based on percentages of annual net sales of certain products subject to license agreements assumed by the Company and a percentage of sublicense revenue. The Company must also make payments to the Holders that are contingent on achieving certain clinical, regulatory and commercial milestones, and may be paid, in the Company’s sole discretion, in cash or shares of the Company’s common stock. The parties made customary representations, warranties, and covenants in the Merger Agreement, including provisions regarding indemnification. Transaction costs associated with the merger of approximately $452,000 are included in the Company’s research and development expense.</div>

<div> 5. Convertible Promissory Notes Prior to the Cerulean/Private Daré stock purchase transaction, Private Daré financed its operations through the sale of convertible promissory notes that entitled the holder to accrued interest at an annual rate of 8%. In the event of a preferred stock financing by Private Daré, all outstanding principal and unpaid interest under the convertible promissory notes would have converted into the shares of Private Daré’s preferred stock issued in such financing at the price per share paid by the purchasers of such shares and an additional number of shares equal to, depending on the time of purchase, 20% to 40% of the outstanding principal and unpaid interest, or the conversion benefit. Private Daré issued a convertible promissory note in the principal amount of $100,000 in February 2017, and between April 1, 2017 and June 6, 2017, Private Daré issued additional convertible promissory notes in the aggregate principal amount of $55,000. In connection with the Cerulean/Private Daré stock purchase transaction, all outstanding convertible promissory notes were amended such that the principal amount of each note plus accrued interest thereon and taking into account the conversion benefit of such note, would convert into shares of common stock of Private Daré immediately prior to the closing of the Cerulean/Private Daré stock purchase transaction. The number of shares of Private Daré common stock issued upon conversion of the convertible promissory notes issued prior to March 31, 2017 was equal to (i) their outstanding principal amount plus accrued interest through March 31, 2017 multiplied by the respective conversion benefit, which ranged from 125% to 140%, divided by (ii) $0.18727. The number of shares of Private Daré common stock issued upon conversion of the convertible promissory notes issued after March 31, 2017 was equal to (i) 120% of their outstanding principal amount, divided by (ii) $0.38. In connection with the closing of the Cerulean/Private Daré stock purchase transaction, all the outstanding shares of common stock of Private Daré, including the shares issued upon conversion of the above described convertible promissory notes, were exchanged for shares of common stock of the Company at the exchange ratio specified in the Daré Stock Purchase Agreement. The Company recognized interest expense of $0 and $18,570 at June 30, 2018 and June 30, 2017, respectively, relating to the convertible promissory notes.</div>

<div> 6. Stock-based Compensation The 2015 Employee, Director and Consultant Equity Incentive Plan <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:7.69%;color:#auto;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Prior to the Cerulean/Private Daré stock purchase transaction, the 2015 Employee, Director and Consultant Equity Incentive Plan of Private Daré, or the 2015 Private Daré Plan, governed the issuance of incentive stock options, non-qualified stock options, stock grants and other stock-based awards to individuals who were then employees, officers, non-employee directors or consultants of Private Daré. Options granted under the 2015 Private Daré Plan have terms of ten years from the date of grant unless earlier terminated and generally vest over a three-year period. Upon closing of the Cerulean/Private Daré stock purchase transaction, the 2015 Private Daré Plan was assumed by the Company and each outstanding option to acquire stock of Private Daré that was not exercised prior to such closing was assumed on the same terms and conditions as were applicable under the 2015 Private Daré Plan, and became an option to acquire such number of shares of the Company’s common stock as was equal to the number of Private Daré shares subject to such unexercised option multiplied by the exchange ratio specified in the Daré Stock Purchase Agreement, at a correspondingly adjusted exercise price. There were outstanding unexercised options to purchase 50,000 shares of Private Daré stock that were assumed in connection with the closing of the Cerulean/Private Daré stock purchase transaction, and which, based on the exchange ratio and after giving effect to the reverse stock split effected in connection with the closing of the Cerulean/Private Daré stock purchase transaction were replaced with options to purchase 10,149 shares of the Company’s common stock, all of which were outstanding as of June 30, 2018. Private Daré issued 900,000 and 200,000 shares of fully vested restricted stock to non-employees under the 2015 Private Daré Plan during the years ended December 31, 2016 and December 31, 2015, respectively. On July 19, 2017, these shares were assumed by the Company and were replaced with 223,295 restricted shares of the Company’s common stock (after giving effect to the reverse stock split effected in connection with the closing of the Cerulean/Private Daré stock purchase transaction), all of which were outstanding as of June 30, 2018. No options or restricted stock were granted under the 2015 Private Daré Plan during the six months ended June 30, 2017, and no further awards may be granted under the 2015 Private Daré Plan following the closing of the Cerulean/Private Daré stock purchase transaction on July 19, 2017. 2014 Employee Stock Purchase Plan In March 2014, the Company’s board of directors adopted, and its stockholders approved the 2014 Employee Stock Purchase Plan, or the ESPP, which became effective in April 2014. The ESPP permits eligible employees to enroll in a six-month offering period whereby participants may purchase shares of the Company’s common stock, through payroll deductions, at a price equal to 85% of the closing price of the common stock on the first day of the offering period or on the last day of the offering period, whichever is lower. Purchase dates under the ESPP occur on or about June 30 and December 31 each year. The board of directors decided against initiating a new offering period beginning January 1, 2017. There was no stock-based compensation related to the ESPP for the six months ended June 30, 2018 or June 30, 2017. 2014 Stock Incentive Plan The Company also maintains the Company’s 2014 Stock Incentive Plan, or the 2014 Plan. When the 2014 Plan was initially adopted, 240,000 shares of common stock were reserved for issuance under the 2014 Plan. In addition, “returning shares” that may become available from time to time are added back to the 2014 Plan. “Returning shares” are shares that are subject to outstanding awards granted under the 2014 Plan and the Company’s 2007 Stock Incentive Plan that expire or terminate prior to exercise or settlement, are forfeited because of failure to vest, or are repurchased. Options granted under the 2014 Plan have terms of no more than ten years from the date of grant unless earlier terminated. On March 19, 2017, the Company’s board of directors approved two modifications to outstanding stock options granted under the 2014 Plan to participants who were providing services to the Company as of that date. One modification extended the exercise period of such stock options to two years after such participant’s termination date, unless the exercise period absent such modification would be longer. The other modification provided for accelerated vesting of such stock options upon a change in control event. These modifications resulted in unamortized fair value expense of approximately $3.7 million and was recorded as part of the total consideration in the Cerulean/Private Daré stock purchase transaction and discussed in Note 4. At June 30, 2018, 138,804 shares of common stock were reserved for future issuance under the 2014 Plan, and options to purchase 537,422 shares of the Company’s common stock granted under the 2014 Plan were outstanding. On May 28, 2018, the Company’s board of directors approved the Amended and Restated 2014 Plan, or the Amended 2014 Plan, which was subsequently approved by the Company’s stockholders on July 10, 2018. The number of shares authorized for issuance of awards under the Amended 2014 Plan was increased from 621,841 to 2,046,885, which is the sum of (a) 1,509,463 shares of common stock plus (b) 537,422 shares of common stock subject to awards granted under the 2014 Plan. An annual increase is to be added on the first day of each fiscal year until, and including, the fiscal year ending December 31, 2024, equal to the least of (i) 2,000,000 shares of common stock, (ii) 4% of the number of outstanding shares of common stock on such date or (iii) an amount determined by the Company’s board of directors. Summary of Stock Option Activity A summary of stock option activity with regard to the 2015 Private Daré Plan and the 2014 Plan, and related information for the six months ended June 30, 2018 is set forth in the table below. The exercise price of all options granted during the six months ended June 30, 2018 and 2017 was equal to the market value of the Company’s common stock on the date of the grant. As of June 30, 2018, unamortized stock-based compensation expense of $35,123 will be amortized over a weighted average period of 2.33 years.   <div> <table border="0" cellspacing="0" cellpadding="0" align="center" style="border-collapse:collapse;

The Company agreed to pay a commission of up to 3% of the gross proceeds of any common stock sold under this agreement plus certain legal expenses. <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:7.69%;letter-spacing:-0.1pt;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">During the six months ended June 30, 2018, the Company generated gross proceeds of approximately $1.1 million and incurred issuance costs of $270,000 under this agreement on sales of an aggregate of 375,000 shares of the Company’s common stock, all of which were sold during January and February 2018. <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;letter-spacing:-0.1pt;font-size:10pt;font-family:Arial;text-transform:none;font-variant: normal;">Underwritten Public Offering <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;letter-spacing:-0.1pt;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">On February 15, 2018, the Company closed an underwritten public offering of 5.0 million shares of its common stock and warrants to purchase up to 3.5 million shares of its common stock. Each share of common stock was sold together with a warrant to purchase up to 0.70 of a share of the Company’s common stock, at an exercise price of $3.00 per share. The offering, including shares issued upon exercise of the underwriter’s overallotment option, generated gross proceeds of $10.3 million, and after the payment of expenses, the Company received net proceeds of approximately $9.4 million. The warrants are exercisable immediately and for a period of five years from the date of issuance. The warrants include a price-based anti-dilution provision, which provides that, subject to certain limited exceptions, the exercise price of the warrants will be adjusted downward if the Company issues or sells (or is deemed to issue or sell) securities at a price that is less than the exercise price in effect immediately prior to such issuance or sale (or deemed issuance or sale), before the expiration of the warrant term. In that case, the new exercise price of the warrants would equal the price at which the new securities are issued or sold (or are deemed to have been issued or sold). In addition, subject to certain exceptions, if the Company issues, sells or enters into any agreement to issue or sell securities at a price which varies or may vary with the market price of the shares of the Company’s common stock, the holders of the warrants shall have the right to substitute such variable price for the exercise price of the warrant then in effect. The warrants are exercisable only for cash, unless the registration statement of which the prospectus registering the offering was part is not effective for the issuance of the shares underlying the warrants, in which case the warrants may be exercised on a cashless basis. The Company granted the underwriters a 30-day option to purchase up to an additional 750,000 shares of its common stock and warrants to purchase up to 525,000 shares of its common stock directly from the Company at a price of $2.05 per common share and accompanying warrant. The Company received an overallotment notice from the underwriter for warrants to purchase up to 220,500 shares of its common stock, which were issued on February 15, 2018. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;letter-spacing:-0.1pt;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company has estimated the fair value of the warrants as of February 15, 2018 to be approximately $3.0 million which has been recorded in equity as of the grant date.

Commitments and Contingencies License and Research Agreements ADVA-Tec License Agreement <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">On March 19, 2017, the Company entered into a license agreement, or the ADVA-Tec Agreement, with ADVA-Tec, Inc., or ADVA-Tec, under which the Company was granted the exclusive right to develop and commercialize Ovaprene for human contraceptive use worldwide. The ADVA-Tec Agreement became effective once the Company secured the initial funding required in accordance with its terms. ADVA-Tec and its affiliates own issued patents or patent applications covering Ovaprene and control proprietary trade secrets covering the manufacture of Ovaprene. As of the date of these interim consolidated financial statements, this patent portfolio includes 12 issued patents worldwide, along with 8 patent applications, all of which in accordance with the terms of the ADVA-Tec Agreement are exclusively licensed to the Company for the human contraceptive use of Ovaprene. The Company also has a right of first refusal to license these patents and patent applications for purposes of additional indications for Ovaprene. Under the ADVA-Tec Agreement, ADVA-Tec will conduct certain research and development work as necessary to allow the Company to seek a Premarket Approval, or PMA, from the United States Food and Drug Administration, or the FDA, and will supply the Company with its requirements of Ovaprene for clinical and commercial use on commercially reasonable terms. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Under the ADVA-Tec Agreement, the Company is required to make payments of up to $14.6 million in the aggregate to ADVA-Tec based on the achievement of specified development and regulatory milestones, which include the completion of a successful Postcoital Clinical Trial Study (as defined in the ADVA-Tec Agreement); approval by the FDA to commence the Phase 3 pivotal human clinical trial; successful completion of the Phase 3 pivotal human clinical trial; the FDA’s acceptance of the filing of a PMA for Ovaprene; the FDA’s approval of the PMA for Ovaprene; obtaining Conformité Européenne Marking of Ovaprene in at least three designated European countries; obtaining regulatory approval in at least three designated European countries; and obtaining regulatory approval in Japan. In addition, after the commercial launch of Ovaprene, the Company is also required to make royalty payments to ADVA-Tec based on aggregate annual net sales of Ovaprene in specified regions, which percentage royalty rate will vary between 1% and 10% and will increase based on various net sales thresholds. Finally, the Company is also required to make up to $20 million in the aggregate in commercial milestone payments to ADVA-Tec upon reaching certain worldwide net sales milestones. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company is obligated to use commercially reasonable efforts to develop and commercialize Ovaprene, and must meet certain minimum spending amounts per year, such amounts totaling $5.0 million in the aggregate over the first three years, to cover such activities until a final PMA is filed, or until the first commercial sale of Ovaprene, whichever occurs first. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The license the Company received under the ADVA-Tec Agreement continues on a country-by-country basis until the later of the life of the licensed patents or the Company’s last commercial sale of Ovaprene. The ADVA-Tec Agreement includes customary termination rights for both parties and provides the Company the right to terminate with or without cause in whole or on a country-by-country basis upon 60 days prior written notice. In addition, ADVA-Tec may terminate the ADVA-Tec Agreement if the Company fails to do any of the following: (i) satisfy the annual spending obligation described above, (ii) use commercially reasonable efforts to complete all necessary pre-clinical and clinical studies required to support and submit a PMA, (iii) conduct clinical trials as set forth in the development plan that is agreed by the Company and ADVA-Tec, and as may be modified by a joint research committee, where such failure is not caused by events outside of the Company’s reasonable control, or (iv) enroll a patient in the first non-significant risk medical device study or clinical trial as allowed by an institutional review board within six months of the production and release of Ovaprene, where non-enrollment is not caused by events outside of its reasonable control. In addition, ADVA-Tec may terminate the ADVA-Tec Agreement if the Company develops or commercializes any non-hormonal ring-based vaginal contraceptive device that is deemed competitive to Ovaprene or, in certain limited circumstances, if the Company fails to commercialize Ovaprene in certain designated countries within three years of the first commercial sale of Ovaprene. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Under the ADVA-Tec Agreement, the Company is required to make payments to ADVA-Tec of up to $14.6 million in aggregate based on the achievement of specified development and regulatory milestones and is also required to make payments of up to $20 million in the aggregate based on the achievement of specified commercial milestones. Because these payments are dependent upon the successful progress of the Company’s product development programs, the Company is unable to estimate with certainty when these milestone payments will occur, if ever. SST License and Collaboration Agreement <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">On February 11, 2018, the Company entered into a license and collaboration agreement, or the SST License Agreement, with Strategic Science & Technologies-D, LLC and Strategic Science & Technologies, LLC, referred to collectively as SST, pursuant to which the Company was required to secure an investment of at least $10 million by March 31, 2018. The Company announced that it had met this funding requirement on February 15, 2018. The SST License Agreement provides the Company with an exclusive, royalty-bearing, sublicensable license to develop and commercialize, in all countries and geographic territories of the world, for all indications for women related to female sexual dysfunction and/or female reproductive health, including treatment of female sexual arousal disorder, or the Field of Use, SST’s topical formulation of Topical 5% Sildenafil Citrate Cream as it exists as of the effective date of the SST License Agreement, or any other topically applied pharmaceutical product containing sildenafil or a salt thereof as a pharmaceutically active ingredient, alone or with other active ingredients, but specifically excluding any product containing ibuprofen or any salt derivative of ibuprofen, or the Licensed Products. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Under the terms of the SST License Agreement, the Company retains rights to inventions made by its employees, SST retains rights to inventions made by its employees, and each party shall own a 50% undivided interest in all joint inventions. Each party has agreed to collaborate through a Joint Development Committee, or JDC, which shall be responsible for determining the strategic objectives for, and generally overseeing, the development efforts of both parties under the SST License Agreement. Further, the Company has agreed to use commercially reasonable efforts to develop the Licensed Products in the Field of Use in accordance with a development plan contained in the SST License Agreement, and to commercialize the Licensed Products in the Field of Use. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The SST License Agreement provides that, in consideration of the rights to be granted to the Company, SST will be eligible to receive tiered royalties based on percentages of annual net sales of Licensed Products in the single digits to the mid double digits, including customary provisions permitting royalty reductions and offset, and a percentage of sublicense revenue. The Company is also responsible for all reasonable internal and external costs and expenses incurred by SST in its performance of the development activities it is required to perform under the SST License Agreement. Further, the SST License Agreement provides that the Company shall make milestone payments to SST ranging from $0.5 million to $18.0 million on achieving certain clinical and regulatory milestones in the U.S. and worldwide, and an additional $10.0 million to $100 million upon achieving certain commercial milestones. Should the Company enter into strategic development or distribution partnerships related to the Licensed Products, additional milestone payments would be due to SST. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company’s license received under the SST License Agreement continues on a country-by-country basis until the later of 10 years from the date of the first commercial sale of such Licensed Product or the expiration of the last valid claim of patent rights covering the Licensed Product in the Field of Use. The SST License Agreement provides that each party will have customary rights to terminate the SST License Agreement in the event of material uncured breach by the other party, and, (i) prior to receipt of approval by a regulatory authority necessary for commercialization of a Licensed Product in the corresponding jurisdiction, including New Drug Application Approval, or NDA Approval, the Company will have the right to terminate the SST License Agreement without cause upon 90 days prior written notice to SST, and (ii) following receipt of approval by a regulatory authority necessary for commercialization of a Licensed Product in the corresponding jurisdiction, including NDA Approval, the Company will have a right to terminate the SST License Agreement without cause upon one 180 days prior written notice. In addition, the SST License Agreement provides SST with the right to terminate the SST License Agreement with respect to the applicable Licensed Product(s) in the applicable country(ies) upon 30 days’ notice to the Company if the Company fails to use commercially reasonable efforts to perform development activities in substantial accordance with the development plan and does not cure such failure within 60 days of receipt of SST’s notice thereof. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Upon expiration (but not termination) of the SST License Agreement in a particular country, the Company shall have a fully paid-up license under the licensed intellectual property to develop and commercialize the applicable Licensed Products in the applicable country on a non-exclusive basis. <p style="text-align:justify;Background-color:#FFFFFF;margin-top:10pt;margin-bottom:0pt;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;text-indent:7.69%;">Orbis Development and Option Agreement On March 12, 2018, the Company entered into an exclusive development and option agreement, or the Orbis Agreement, with Orbis Biosciences, or Orbis, for the development of long-acting injectable etonogestrel contraceptive with 6- and 12-month durations (ORB-204 and ORB-214, respectively). The Company has agreed to pay Orbis $300,000 to conduct the first stage of development work, Stage 1, as follows: $150,000 upon signing the Orbis Agreement, $75,000 at the 50% completion point, not later than 6 months following the date the Orbis Agreement was signed, and $75,000 upon delivery by Orbis of the 6-month batch, not later than 11 months following the date the Orbis Agreement was signed. Upon Orbis successfully completing Stage 1 of the development program and achieving the predetermined target milestones for Stage 1, the Company will have 90 days to instruct Orbis whether to commence the second stage of development work, Stage 2. Should the Company execute its option to proceed to Stage 2, it will be obligated to provide additional funding to Orbis for such activities. The initial development on Orbis’s long-acting injectable contraceptive program was carried out under a subcontract funded by Family Health International, or FHI 360, through a grant from the Bill and Melinda Gates Foundation, or the Gates Foundation. The Gates Foundation and FHI 360 are world leaders in the funding and development of novel contraceptive products and programs. In July of 2017, the Gates Foundation announced a commitment of $375 million over three years in support of Family Planning 2020, a global public/private partnership aimed at providing access to contraception. An injectable contraceptive is designed to provide discreet, non-implanted, protection over periods of months. Limitations of the currently marketed injectable contraceptive is that it provides contraceptive protection for only three months and can delay the ability to get pregnant for up to ten months after receiving the injection. The target product profiles of ORB-204 and ORB-214 include prolonged duration (6 to 12 months), improved ease of use, with an improved side effect profile and predictable return to fertility. Pre-clinical studies for the 6- and 12-month formulations have been completed to date, including establishing pharmacokinetics and pharmacodynamics profiles. The collaboration with Orbis will continue to advance the program through formulation optimization with the goal of achieving sustained release over the target time period. The Orbis Agreement provides the Company with an option to enter into a license agreement for ORB-204 and ORB-214 should upcoming development efforts be successful. Juniper Pharmaceuticals - License Agreement On April 24, 2018, the Company entered into an Exclusive License Agreement, or the Juniper License Agreement, with Juniper Pharmaceuticals, Inc., or Juniper, pursuant to which Juniper granted the Company (a) an exclusive, royalty-bearing worldwide license under certain patent rights, either owned by or exclusively licensed to Juniper, to make, have made, use, have used, sell, have sold, import and have imported products and processes; and (b) a non-exclusive, royalty-bearing worldwide license to use certain technological information owned by Juniper to make, have made, use, have used, sell, have sold, import and have imported products and processes. The Company is entitled to sublicense the rights granted to it under the Juniper License Agreement. The following is a summary of the material terms of the Juniper License Agreement: •Upfront Fee. The Company paid a $250,000 non-creditable upfront license fee to Juniper in connection with the execution of the Juniper License Agreement. •Annual Maintenance Fee. The Company will pay an annual license maintenance fee to Juniper on each anniversary of the date of the Juniper License Agreement, the amount of which will be $50,000 for the first two years and $100,000 thereafter, and which will be creditable against royalties and other payments due to Juniper in the same calendar year but may not be carried forward to any other year. •Milestone Payments. The Company is required to make potential future development and sales milestone payments of up to $43.8 million (up to $13.5 million in clinical and regulatory milestones and up to $30.3 million in sales milestones) for each product or process covered by the licenses granted under the Juniper License Agreement. •Royalty Payments. During the royalty term, the Company will pay Juniper mid-single-digit to low double-digit royalties based on worldwide net sales of products and processes covered by the licenses granted under the Juniper License Agreement. In lieu of such royalty payments, the Company will pay Juniper a low double-digit percentage of all sublicense income that the Company receives for the sublicense of rights under the Juniper License Agreement to a third party. The royalty term, which is determined on a country-by-country basis and product-by-product basis (or process-by-process basis), begins with the first commercial sale of a product or process in a country and terminates on the latest of (1) the expiration date of the last valid claim within the licensed patent rights with respect to such product or process in such country, (2) 10 years following the first commercial sale of such product or process in such country, and (3) when one or more generic products for such product or process are commercially available in such country, except that if there is no such generic product by the 10th year following the first commercial sale in such country, then the royalty term will terminate on the 10-year anniversary of the first commercial sale in such country. •Efforts. The Company is required to use commercially reasonable efforts to develop and make at least one product or process available to the public, which efforts include achieving specific diligence requirements by specific dates specified in the Juniper License Agreement. •Term. Unless earlier terminated, the term of the Juniper License Agreement will continue on a country-by-country basis until the later of (1) the expiration date of the last valid claim within such country, or (2) 10 years from the date of first commercial sale of a product or process in such country. Upon expiration (but not early termination) of the Juniper License Agreement, the licenses granted thereunder will convert automatically to fully-paid irrevocable licenses. Juniper may terminate the Juniper License Agreement (1) upon 30 days’ notice for the Company’s uncured breach of any payment obligation under the Juniper License Agreement, (2) if the Company fails to maintain required insurance, (3) immediately upon the Company’s insolvency or the making of an assignment for the benefit of the Company’s creditors or if a bankruptcy petition is filed for or against the Company, which petition is not dismissed within 90 days, or (4) upon 60 days’ notice for any uncured material breach by the Company of any of its other obligations under the Juniper License Agreement. The Company may terminate the Juniper License Agreement on a country-by-country basis for any reason by giving 180 days’ notice (or 90 days’ notice if such termination occurs prior to receipt of marketing approval in the United States). If Juniper terminates the Juniper License Agreement for the reason described in clause (4) above or if the Company terminates the Juniper License Agreement, Juniper will have full access including the right to use and reference all product data generated during the term of the Juniper License Agreement that is owned by the Company. Pear Tree Acquisition The Company must also make certain royalty and milestone payments under the Merger Agreement. See the discussion under the “Pear Tree Merger” heading in Note 4, “Acquisitions,” above. Funding Award from the National Institutes of Health On April 30, 2018, the Company announced that it received a Notice of Award for the first $224,665 of the anticipated $1.9 million in grant funding from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, a division of the National Institutes of Health.  The award will be applied to important clinical development efforts supporting the Company’s lead product candidate, Ovaprene. The balance of the award is contingent upon, among other matters, assessment of the results of the first phase of the research and availability of funds. The Company must incur and track expenses eligible for reimbursement under the award and submit a detailed accounting of such expenses in order to receive payment.</div>

<div> 9. Net Loss Per Share The Company computes basic net loss per share using the weighted average number of common shares outstanding during the period. Diluted net income per share is based upon the weighted average number of common shares and potentially dilutive securities (common share equivalents) outstanding during the period. Common share equivalents outstanding, determined using the treasury stock method, are comprised of shares that may be issued under outstanding options and warrants to purchase shares of the Company’s common stock. Common share equivalents are excluded from the diluted net loss per share calculation if their effect is anti-dilutive. The following potentially dilutive outstanding securities were excluded from diluted net loss per common share for the period indicated because of their anti-dilutive effect:   <div> <table border="0" cellspacing="0" cellpadding="0" align="center" style="border-collapse:collapse;

<div> Recently Adopted Accounting Standards In May 2014, FASB issued Accounting Standards Update, or ASU, 2014-09, Revenue from Contracts with Customers, which impacts the way in which some entities recognize revenue for certain types of transactions. The new standard became effective beginning in 2018 for public companies. Because the Company does not currently have any contracts with customers, the Company’s adoption of this accounting standard did not impact the Company. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which intended to add or clarify guidance on the classification of certain cash receipts and payments on the statement of cash flows. The new guidance addresses cash flows related to the following: debt prepayment or extinguishment costs, settlement of zero-coupon bonds, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies and bank-owned life insurance policies, distributions received from equity method investees, beneficial interest in securitization transactions, and the application of predominance principle to separately identifiable cash flows. The standard became effective on January 1, 2018. The Company’s adoption of this standard on January 1, 2018 did not have a material impact on the Company’s interim consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In January 2017, FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which intended to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard became effective for the Company on January 1, 2018. The Company’s early adoption of this standard did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance should be adopted on a prospective basis for the annual or any interim goodwill impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company’s adoption of this standard on September 30, 2017 did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:10pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In May 2017, FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, which intended to provide clarity when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The standard became effective for the Company on January 1, 2018. The Company’s adoption of this standard did not have a material impact on the Company’s consolidated financial statements. <p style="text-align:justify;margin-top:6pt;margin-bottom:0pt;text-indent:7.69%;color:#000000;font-size:10pt;font-family:Arial;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In July 2017, FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815): (I) Accounting for Certain Financial Instruments with Down Round Features, (II) Replacement for the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. This update was issued to provide additional clarity related to accounting for certain financial instruments that have characteristics of both liabilities and equity. In particular, this update addresses freestanding and embedded financial instruments with down round features and whether they should be treated as a liability or equity instrument. Part II simply replaces the indefinite deferral for certain mandatorily redeemable non-controlling interests and mandatorily redeemable financial instruments of nonpublic entities contained within the ASC Topic 480 with a scope exception and does not impact the accounting for these mandatorily redeemable instruments. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company has early adopted ASU 2017-11. As a result, the Company has not recognized the fair value of the warrants containing down round features that were issued in the underwritten offering in February 2018 (see Note 7) as liabilities.</div>
