The Company granted 100,000 stock options, with a weighted-average grant date fair value of $2.81per share, during the three and six months ended June 30, 2014.

During the six months ended June 30, 2015, 28,333 stock options previously granted have vested and 278,334 stock options were forfeited and no stock options were exercised.

The Company’s long-term performance-based incentive program for executive officers (the “Executive LTIP Program”) and its long-term performance-based equity incentive based component for the non-employee directors (“Non-Employee Director LTIP Program” and together with the Executive LTIP the “LTIP Programs”) expired and terminated in accordance with their terms on December 31, 2014. The Compensation Committee of the Board of Directors (the “Compensation Committee”) recommended and approved, and the Board of Directors approved, a program of equity based awards from the Company’s 2012 Equity Incentive Plan (the “2012 Plan”) which are intended to align interests of executive officers and directors with stockholders over a long-term basis and thereby replace the expired LTIP Programs. The new equity based programs also include a minimum dollar value stock ownership holding requirement threshold before shares can be sold.

On March 16, 2015, in connection with and in furtherance of the new equity based award program, the Board of Directors of the Company approved stock option awards as previously recommended and approved by the Compensation Committee for the Company’s named executive officers currently employed with the Company. Mr. Sullivan, the Company’s Chief Financial Officer, Mr. Fosmoe, the Company’s Senior Vice President of Operations/Product Development and Dr. Handfield, the Company’s Senior Vice President of Discovery Research, were granted options to purchase 200,000, 150,000 and 150,000 shares of Company common stock, respectively, under the Company’s 2012 Plan at an exercise price of $1.32 per share, the closing price on the date of grant. The options are subject to time-based vesting in equal annual installments over a three-year period on the first, second and third anniversaries of the date of the grant, provided that the recipient remains employed with the Company through the vesting dates.

Also on March 16, 2015, in connection with and in furtherance of the new equity based award program, the Board approved stock option awards in the amount of 80,000 to each of the Company’s non-employee directors, Frederick Telling, Charles Pope, Alan Dunton, Christine Koski and Robert Koski under the Company’s 2012 Plan at an exercise price of $1.32 per share, the closing price on the date of grant. Dr. Telling, Mr. Pope, Dr. Dunton, Ms. Koski and Mr. Koski were each also awarded 40,000 restricted shares of Company common stock under the Company’s 2012 Plan, of which 10,000 restricted shares vest at the end of each calendar quarter in 2015, provided the recipient remains a director through the vesting date.

Each executive officer and non-employee director receiving the above equity based awards will be subject to a minimum dollar value stock ownership holding requirement with respect to the awards received as well as all prior equity awards under the 2012 Plan which requirements are intended to align the ability to sell shares with the performance of the Company’s stock price. The above named executive officer recipients will each have a minimum dollar value stock ownership holding requirement threshold equal to two times (2x) their then base salaries below which dollar threshold they would be precluded from selling any shares of Company stock obtained from the Company under its 2012 Plan. Also, the above non-employee directors will each be subject to a minimum dollar value stock ownership holding requirement threshold equal to six times the annual Board retainer ($270,000) below which dollar threshold they would be precluded from selling shares of Company stock acquired from the Company under its 2012 Plan.
