These costs are classified as management and administrative expense. Effective August 1, 2016, the consulting agreement was terminated and all outstanding options issued for consulting services were rescinded by mutual consent of the parties. Options issued under the 2011 Stock Option/Restricted Plan The Company established the 2011 Stock Option/Restricted Stock Plan. The Stock Option Plan is administered by the Board of Directors and provides for the grant of stock options to eligible individual including directors, executive officers and advisors that have furnished bona fide services to the Company not related to the sale of securities in a capital-raising transaction. The Stock Option Plan has a fixed maximum percentage of 10% of the Company's outstanding shares that are eligible for the plan pool, whereby the number of Shares under the plan increases automatically increases as the total number of shares outstanding increase. The number of shares subject to the Stock Option Plan and any outstanding awards will be adjusted appropriately by the Board of Directors if the Company's common stock is affected through a reorganization, merger, consolidation, recapitalization, restructuring, reclassification dividend (other than quarterly cash dividends) or other distribution, stock split, spin-off or sale of substantially all of the Company's assets. The Stock Option plan also has terms and conditions, including without limitations that the exercise price for stock options granted under the Stock Option Plan must equal the stock's fair market value, based on the closing price per share of common stock, at the time the stock option is granted. The fair value of each option award is estimated on the date of grant utilizing the Black-Scholes model and commonly utilized assumptions associated with the Black-Scholes methodology. Options granted under the Plan have a ten-year maximum term and varying vesting periods as determined by the Board. On October 18, 2016, the Company rescinded 2,696,667 fully vested options previously granted under the Stock Option plan with a weighted average exercise price of $0.37. The Company re-issued the options and granted an additional 2,116,333 options to purchase shares of the Company's common stock, or a total of 4,810,000 options, with an exercise price of $0.06 per share. The options vested immediately and have a term of 5 years. The Company accounted for the repricing as a modification of stock option terms.
