Stock Option Plan and Stock Grants
The Company’s Stock Option and Stock Award Plan (the “Plan”) was adopted in December 1992 and amended and restated from time to time, most recently effective March 23, 2001. Pursuant to the Plan, officers, directors, employees and consultants of the Company are offered the opportunity (i) to acquire shares of common stock through the grant of stock options (“Options”), including non-qualified stock options and, for key employees, incentive stock options within the meaning of Section 422 of the Internal Revenue Code; and (ii) to be awarded shares of common stock (“Restricted Stock Grants”), subject to conditions and restrictions determined by the Compensation, Nominating, and Corporate Governance Committee of the Company’s Board of Directors (the “Compensation Committee”). The Compensation Committee will determine the vesting schedule, if any, of each Option and the term, which term shall not exceed ten years from the date of grant. As to the Options that have been granted through December 31, 2012 to officers and employees, generally, one-third are exercisable one year after the initial grant, one-third are exercisable two years following the date such Options were granted and the remaining one-third are exercisable three years following the date such Options were granted. Shares that did not vest were forfeited. Dividends are paid on restricted stock and are not returnable, even if the underlying stock does not entirely vest. Stock Options are awarded at the New York Stock Exchange closing price of the Company’s common stock on the grant date. A maximum of 6,000,000 shares of common stock are available for grant under the Plan and no more than 250,000 shares may be subject to grants to any one individual in any calendar year.
Grants under the Plan are made by the Compensation Committee, which determines the individuals eligible to receive awards, the types of awards, and the terms, conditions and restrictions applicable to any award. In addition, the terms of two specific types of awards are contemplated under the Plan:

The first type of award is a grant of Options or Restricted Stock Grants of common stock made to each member of the Board at the meeting held immediately after each annual meeting of the Company’s stockholders. Generally, if the director elects to receive Options, the grant will cover 10,000 shares of common stock at an exercise price equal to the fair market value on the date of grant. If the director elects to receive a Restricted Stock Grant of common stock, he or she will receive an award of 2,000 shares of common stock. Exercisability or vesting with respect to either type of award will be one-third of the award after six months, two-thirds of the award after one year, and the full award after two years.

The second type of award is a grant of common stock in lieu of 50% of their bonus otherwise payable to individuals with a title of Vice President or above. A recipient can request that the Compensation Committee pay a greater or lesser portion of the bonus in shares of common stock.
 
The Company accounts for its stock-based compensation in accordance with FASB ASC 718.
