The valuation methodology used to determine the fair value of our warrants is the Black-Scholes Model. The Black-Scholes Model requires the use of a number of assumptions, including volatility of the stock price, the risk-free interest rate, dividend yield and the term of the warrant. During the year ended December 31, 2017, we granted warrants to purchase 125,000 shares of Common Stock to outside consultants at an exercise price of $6.83 per share. The fair value for these warrants was determined by using the Black-Scholes Model on the date of the grant using a term of five years; volatility of 63.24%; risk free rate of 1.47%; and dividend yield of 0%. The grant date fair value of the warrants was $3.67 per share. The warrants vest ratably over a 12-month period and have an expiration date of March 15, 2022. During the year ended December 31, 2016, we granted warrants to purchase 245,000 shares of Common Stock to outside consultants at the weighted average price of $7.90 per share. These warrants vest and have expiration dates as follows: warrants to purchase 75,000 shares of Common Stock vested on April 21, 2016 and have an expiration date of April 21, 2021, warrants to purchase 50,000 shares of Common Stock vest ratably over a 24-month period and have an expiration date of April 21, 2021, and warrants to purchase 120,000 shares of Common Stock vest ratable over a 12-month period and have an expiration date of January 21, 2021.

At December 31, 2017, total unrecognized estimated compensation expense related to the unvested portion of these warrants was approximately $128,000 which is expected to be recognized over a weighted-average period of 0.2 years. Summary of our Warrant activity during the year ended December 31, 2017: Number of Weighted Weighted Aggregate Balance at December 31, 2016 12,060,071 $ 2.08 1.0 $ 45,063,867 Granted 125,000 $ 6.83 Exercised (9,066,666 ) $ 1.98 $ 48,535,969 Expired (2,500 ) $ 2.64 Cancelled/Forfeited — $ — Balance at December 31, 2017 3,115,905 $ 2.58 1.8 $ 11,348,273 Vested and Exercisable at December 31, 2017 2,792,983 $ 2.64 0.8 $ 1,141,836 Unvested at December 31, 2017 322,922 $ 2.57 2.0 $ 10,206,436 The aggregate intrinsic value of warrants exercised during 2016 and 2015, was $3,988,343 and $7,282,404, respectively. 2017 2016 2015 Weighted average exercise price $ 6.83 $ 7.90 $ 6.35 Weighted average grant date fair value $ 3.67 $ 4.78 $ 3.27 Risk-free interest rate 1.47 % 1.04-1.28 % 1.02 % Volatility 63.24 % 74.10-74.15 % 60.59 % Term (in years) 5 5 5 Dividend yield 0.00 % 0.00 % 0.00 % The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds whose maturity period is appropriate for the term of the instrument. Estimated volatility is a measure of the amount by which our stock price is expected to fluctuate each year during the term of the instrument. The estimated volatility is an average of the historical volatility of the stock prices of our peer entities whose stock prices were publicly available. Our calculation of estimated volatility is based on historical stock prices over a period equal to the term of the instrument as we have insufficient historical information regarding our stock options to provide a basis for estimate. The expected volatility of warrants was estimated based on a historical volatility analysis of peers that were similar to the Company with respect to industry, stage of life cycle, market capitalization, and financial leverage. In May 2013, we entered into a consulting agreement with Sancilio and Company, Inc., or SCI, to develop drug platforms to be used in our hormone replacement drug candidates. These services include support of our efforts to successfully obtain U.S. Food and Drug Administration, or the FDA, approval for our drug candidates, including a vaginal capsule for the treatment of vulvar and vaginal atrophy, or VVA. In connection with the agreement, SCI agreed to forfeit its rights to receive warrants to purchase 833,000 shares of our Common Stock that were to be granted pursuant to the terms of a prior consulting agreement dated May 17, 2012. As consideration under the agreement, we agreed to issue to SCI a warrant to purchase 850,000 shares of our Common Stock at $2.01 per share that has vested or will vest, as applicable, as follows: 1. 283,333 shares were earned on May 11, 2013 upon acceptance of an Investigational New Drug application by the FDA for an estradiol-based drug candidate in a softgel vaginal capsule for the treatment of VVA; however, pursuant to the terms of the consulting agreement, the shares did not vest until June 30, 2013. The fair value of $405,066 for the shares vested on June 30, 2013 was determined by using the Black-Scholes Model on the date of vesting using a term of 5 years; a volatility of 45.89%; risk free rate of 1.12%; and a dividend yield of 0%. We recorded the entire $405,066 as non-cash compensation as of June 30, 2013. These shares were exercised in 2017 and are included in the warrant exercise details below; 2. 283,333 shares vested on June 30, 2013. The fair value of $462,196 for these shares was determined by using the Black-Scholes Model on the date of vesting using a term of 5 years; a volatility of 45.84%; risk free rate of 1.41%; and a dividend yield of 0%. During the years ended December 31, 2017, 2016, and 2015, we recorded $0, $77,026, and $154,068, respectively, as non-cash compensation in the accompanying consolidated financial statements related to this warrant. As of December 31, 2017 this warrant was fully amortized. These shares were exercised in 2017 and are included in the warrant exercise details below; and 3. 283,334 shares will vest upon the receipt by us, prior to the warrant expiration date of April 30,2018, of any final FDA approval of a drug candidate that SCI helped us design. It is anticipated that receipt of such an approval may occur in the near future. In May 2012, we issued warrants to purchase an aggregate of 1,300,000 shares of Common Stock to SCI for services to be rendered over approximately five years beginning in May 2012. The warrants vested upon issuance. Services provided are to include (a) services in support of our drug development efforts, including services in support our ongoing and future drug development and commercialization efforts, regulatory approval efforts, third-party investment and financing efforts, marketing efforts, chemistry, manufacturing and controls efforts, drug launch and post-approval activities, and other intellectual property and know-how transfer associated therewith; (b) services in support of our efforts to successfully obtain new drug approval; and (c) other consulting services as mutually agreed upon from time to time in relation to new drug development opportunities. The warrants were valued at $1,532,228 on the date of the issuance using an exercise price of $2.57; a term of five years; a volatility of 44.71%; risk free rate of 0.74%; and a dividend yield of 0%. During the years ended December 31, 2017, 2016, and 2015, we recorded $128,898, $257,796, and $257,796, respectively as non-cash compensation with respect to these warrants in the accompanying consolidated financial statements.

Options to Purchase Common Stock of the Company In 2009, we adopted the 2009 Long Term Incentive Compensation Plan, or the 2009 Plan, to provide financial incentives to employees, directors, advisers, and consultants of our company who are able to contribute towards the creation of or who have created stockholder value by providing them stock options and other stock and cash incentives, or the Awards. The Awards available under the 2009 Plan consist of stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock, performance units, and other stock or cash awards as described in the 2009 Plan. There are 25,000,000 shares authorized for issuance thereunder. Generally, the options vest annually over four years or as determined by our board of directors, upon each option grant. Options may be exercised by paying the price for shares or on a cashless exercise basis after they have vested and prior to the specified expiration date provided and applicable exercise conditions are met, if any. The expiration date is generally ten years from the date the option is issued. As of December 31, 2017, there were non-qualified stock options to purchase 18,575,084 shares of Common Stock outstanding under the 2009 Plan. As of December 31, 2017, there were 2,173,878 shares available to be issued under 2009 Plan. In 2012, we adopted the 2012 Stock Incentive Plan, or the 2012 Plan, a non-qualified plan that was amended in August 2013. The 2012 Plan was designed to serve as an incentive for retaining qualified and competent key employees, officers, directors, and certain consultants and advisors of our company. The Awards available under the 2012 Plan consist of stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock, performance units, and other stock or cash awards as described in the 2012 Plan. Generally, the options vest annually over four years or as determined by our board of directors, upon each option grant. Options may be exercised by paying the price for shares or on a cashless exercise basis after they have vested and prior to the specified expiration date provided and applicable exercise conditions are met, if any. The expiration date is generally ten years from the date the option is issued. There are 10,000,000 shares of Common Stock authorized for issuance thereunder. As of December 31, 2017, there were non-qualified stock options to purchase 4,790,141 shares of Common Stock outstanding under the 2012 Plan. As of December 31, 2017, there were 5,128,333 shares available to be issued under 2012 Plan. The valuation methodology used to determine the fair value of stock options is the Black-Scholes Model. The Black-Scholes Model requires the use of a number of assumptions including volatility of the stock price, the risk-free interest rate, and the expected life of the stock options. The ranges of assumptions used in the Black-Scholes Model during the years ended December 31, 2017, 2016, and 2015 are set forth in the table below. 2017 2016 2015 Weighted average exercise price $ 6.60 $ 6.22 $ 8.14 Weighted average grant date fair value $ 3.82 $ 3.94 $ 4.45 Risk-free interest rate 1.84-2.05 % 1.13-1.90 % 1.47-1.67 % Volatility 61.56-64.25 % 70.26-73.34 % 58.78-62.94 % Term (in years) 5.5-6.25 5.5-6.25 5.27-6.25 Dividend yield 0.00 % 0.00 % 0.00 % The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds whose maturity period is appropriate for the expected term. Estimated volatility is a measure of the amount by which the price of our Common Stock is expected to fluctuate each year during the term of an award. Our estimated volatility is an average of the historical volatility of the stock prices of our peer entities whose stock prices were publicly available. Our calculation of estimated volatility is based on historical stock prices over a period equal to the term of the awards as we have insufficient historical information regarding our stock options to provide a basis for estimate. The expected volatility of share options was estimated based on a historical volatility analysis of peers that were similar to us with respect to industry, stage of life cycle, market capitalization, and financial leverage. The average expected life is based on the contractual terms of the stock option using the simplified method. We utilize a dividend yield of zero based on the fact that we have never paid cash dividends and have no current intention to pay cash dividends. Future stock-based compensation may significantly differ based on changes in the fair value of our Common Stock and our estimates of expected volatility and the other relevant assumptions. A summary of activity under the 2009 and 2012 Plans and related information during the year ended December 31, 2017 is as follows: Number of Weighted Weighted Aggregate Balance at December 31, 2016 21,767,854 $ 3.56 5.8 $ 60,495,730 Granted 2,271,500 $ 6.60 Exercised (102,546 ) $ 2.07 $ 452,287 Expired (108,375 ) $ 7.64 Cancelled/Forfeited (463,208 ) $ 6.28 Balance at December 31, 2017 23,365,225 $ 3.78 5.13 $ 64,664,821 Vested and Exercisable at December 31, 2017 19,770,142 $ 3.27 4.47 $ 63,895,512 Unvested at December 31, 2017 3,595,083 $ 6.60 8.79 $ 769,309 At December 31, 2017, our outstanding options had exercise prices ranging from $0.10 to $8.92 per share. The aggregate intrinsic value of options exercised during 2016 and 2015, was $3,828,358 and $3,186,371, respectively. Share-based compensation expense related to options recognized in our results of operations for the years ended December 31, 2017, 2016, and 2015 was approximately $6,447,154, $16,139,225, and $6,621,658, respectively, and it is based on awards vested. At December 31, 2017, total unrecognized estimated compensation expense related to unvested options was approximately $10,596,000, which may be adjusted for future changes in forfeitures. This cost is expected to be recognized over a weighted-average period of 2.1 years. No tax benefit was realized due to a continued pattern of operating losses. |
