The Anika Therapeutics, Inc. Stock Option and Incentive Plan, as amended, (the “2003 Plan”) provides for grants of nonqualified and incentive stock options, common stock, restricted stock, restricted stock units, and stock appreciation rights (“SAR’s”) to employees, directors, officers and consultants. The 2003 Plan was originally approved by the Board of Directors on April 4, 2003, approved by the Company’s shareholders on June 4, 2003, and reserved 1,500,000 shares of common stock for grant pursuant to its terms.

On May 29, 2009, the Board of Directors approved changes to the 2003 Plan and adopted the Amended and Restated 2003 Stock Option and Incentive Plan (the “Amended 2003 Plan”), to increase the number of shares available to grant by 850,000. The Amended 2003 Plan was approved by the Company’s shareholders on June 5, 2009, and resulted in a total of 2,350,000 shares of common stock being reserved for issuance under the Amended 2003 Plan.

At the 2011 Annual Meeting of Stockholders on June 7, 2011, the shareholders of the Company approved the Anika Therapeutics, Inc. Second Amended and Restated Stock Option and Incentive Plan (the “2003 Plan”), which, among other things, increased the number of shares reserved for issuance under the Company’s predecessor stock option and incentive plan by 800,000 to 3,150,000 shares.

At the 2013 Annual Meeting of Stockholders on June 18, 2013, the shareholders of the Company approved an additional amendment to the Amended 2003 Plan, which among other things, increased the number of shares reserved for issuance under the Company’s stock option and incentive plan by 650,000 to 3,800,000 shares.

The Company may satisfy the awards upon exercise, or upon fulfillment of the vesting requirements for other equity-based awards, with either newly-issued shares or shares reacquired by the Company. Stock-based awards are granted with an exercise price equal to the market price of the Company’s stock on the date of grant. Awards contain service or performance conditions and generally become exercisable ratably over one to four years.

The 2003 Plan succeeds the Anika Therapeutics, Inc. 1993 Stock Option Plan (“1993 Plan”) which expired according to its terms in 2003. As of December 31, 2013, there were no shares outstanding under the 1993 Plan included in the total outstanding options of 1,513,326. There are 1,266,036 options available for future grant at December 31, 2013.

The Company estimates the fair value of stock options and SAR’s using the Black-Scholes valuation model. Fair value of restricted stock is measured by the grant-date price of the Company’s shares. Key input assumptions used to estimate the fair value of stock options and SAR’s include the exercise price of the award, the expected award term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the award’s expected term, and the Company’s expected annual dividend yield.

The Company uses historical data on exercise of stock options and other factors to evaluate and estimate the expected term of share-based awards. The Company also evaluates actual forfeiture rates periodically and adjusts the expected forfeiture rate assumption within the model accordingly. The expected volatility assumption is evaluated against the historical volatility of the Company’s common stock over a four year average and is adjusted if there are material swings in historical volatility. The risk-free interest rate assumption is based on U.S. Treasury interest rates at the time of grant.

The fair value of each stock option and SAR award during 2013, 2012, and 2011 was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions:
