Section 6. Non-Qualified Stock Options

6.1  Grant of Non-Qualified Stock Options.

The Board of Directors may, from time to time, grant Non-Qualified Stock Options to Participants upon such terms and conditions as the Board of Directors may determine. Non-Qualified Stock Options granted under this Plan are subject to the following terms and conditions:

(a)  Price. The purchase price per share of Common Stock deliverable upon the exercise of each Non-Qualified Stock Option shall be determined by the Board of Directors on the date the option is granted. Such purchase price shall not be less than one hundred percent (100%) of the Fair Market Value of the Common Stock on the date of grant. Shares may be purchased only upon full payment of the purchase price. Payment of the purchase price may be made, in whole or in part, through the surrender of shares of the Common Stock at the Fair Market Value of such shares on the date of surrender, or through such other consideration as the Board of Directors shall determine is appropriate.

(b)  Terms of Options. The term during which each Non-Qualified Stock Option may be exercised shall be determined by the Board of Directors, but in no event shall a Non-Qualified Stock Option be exercisable in whole or in part more than ten (10) years from the date of grant. No Non-Qualified Stock Option granted under this Plan is transferable except by will or the laws of descent and distribution.

4

(c)  Termination of Service. Except as provided in Section 6.1(d) hereof, unless otherwise determined by the Board of Directors, upon the termination of a Participant’s service as an employee or member of the Board of Directors for any reason other than Disability, death or Termination for Cause, the Participant’s Non-Qualified Stock Options shall be exercisable only as to those shares which were immediately exercisable by the Participant at the date of termination and only for a period of three months following termination. Notwithstanding any provision set forth herein nor contained in any Agreement relating to the award of an Option, in the event of Termination for Cause, all rights under the Participant’s Non-Qualified Stock Options shall expire upon termination. In the event of death or termination of service as a result of Disability of any Participant, all Non-Qualified Stock Options held by the Participant, whether or not exercisable at such time, shall be exercisable by the Participant or his legal representatives or beneficiaries of the Participant for one year or such longer period as determined by the Board following the date of the Participant’s death or termination of service due to Disability, provided that in no event shall the period extend beyond the expiration of the Non-Qualified Stock Option term.

(d)  Exception for Retirement. Notwithstanding the general rule contained in Section 6.1(c) above, all options which are then currently exercisable held by a Participant whose employment with the Corporation terminates due to Retirement may be exercised for the lesser of (i) the remaining term of the option, or (ii) twelve (12) months.

Section 7. Incentive Stock Options

7.1  Grant of Incentive Stock Options. The Board of Directors may, from time to time, grant Incentive Stock Options to eligible employees. Incentive Stock Options granted pursuant to the Plan shall be subject to the following terms and conditions:

(a)  Price. The purchase price per share of Common Stock deliverable upon the exercise of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock on the date of grant. However, if a Participant owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of Common Stock, the purchase price per share of Common Stock deliverable upon the exercise of each Incentive Stock Option shall not be less than one hundred ten percent (110%) of the Fair Market Value of the Common Stock on the date of grant. Shares may be purchased only upon payment of the full purchase price. Payment of the purchase price may be made, in whole or in part, through the surrender of shares of the Common Stock at the Fair Market Value of such shares on the date of surrender, or through such other consideration as the Board of Directors shall determine is appropriate.

5

(b)  Amounts of Options. Incentive Stock Options may be granted to any eligible employee in such amounts as determined by the Board of Directors. In the case of an option intended to qualify as an Incentive Stock Option, the aggregate Fair Market Value (determined as of the time the option is granted) of the Common Stock with respect to which Incentive Stock Options granted are exercisable for the first time by the Participant during any calendar year shall not exceed $100,000. The provisions of this Section 7.1(b) shall be construed and applied in accordance with Section 422(d) of the Code and the regulations, if any, promulgated thereunder. To the extent an award is in excess of such limit, it shall be deemed a Non-Qualified Stock Option. The Board shall have discretion to redesignate options granted as Incentive Stock Options as Non-Qualified options.

(c)  Terms of Options. The term during which each Incentive Stock Option may be exercised shall be determined by the Board of Directors, but in no event shall an Incentive Stock Option be exercisable in whole or in part more than ten (10) years from the date of grant. If at the time an Incentive Stock Option is granted to an employee, the employee owns Common Stock representing more than ten percent (10%) of the total combined voting power of the Corporation (or, under Section 422(d) of the Code, is deemed to own Common Stock representing more than ten percent (10%) of the total combined voting power of all such classes of Common Stock, by reason of the ownership of such classes of Common Stock, directly or indirectly, by or for any brother, sister, spouse, ancestor or lineal descendent of such employee, or by or for any corporation, partnership, estate or trust of which such employee is a shareholder, partner or beneficiary), the Incentive Stock Option granted to such employee shall not be exercisable after the expiration of five years from the date of grant. No Incentive Stock Option granted under this Plan is transferable except by will or the laws of descent and distribution.

(d)  Termination of Employment. Except as provided in Section 7.1(e) hereof, upon the termination of a Participant’s service for any reason other than Disability, death or Termination for Cause, the Participant’s Incentive Stock Options which are then exercisable at the date of termination may only be exercised by the Participant for a period of three months following termination, after which time they shall be void. Notwithstanding any provisions set forth herein nor contained in any Agreement relating to an award of an Option, in the event of Termination for Cause all rights under the Participant’s Incentive Stock Options shall expire immediately upon termination.

Unless otherwise determined by the Board of Directors, in the event of death or termination of service as a result of Disability of any Participant, all Incentive Stock Options held by such Participant, whether or not exercisable at such time, shall be exercisable by the Participant or the Participant’s legal representatives or the beneficiaries of the Participant for one year following the date of the Participant’s death or termination of employment as a result of Disability. In no event shall the exercise period extend beyond the expiration of the Incentive Stock Option term.

(e)  Exception for Retirement. Notwithstanding the general rule contained in Section 7.1(d) above, all options which are then exercisable held by a Participant whose employment with the Corporation terminates due to Retirement may be exercised for the lesser of (i) the remaining term of the option or (ii) three (3) months.

6

(f)   Compliance with Code. The options granted under this Section 7 of the Plan are intended to qualify as incentive stock options within the meaning of Section 422 of the Code, but the Corporation makes no warranty as to the qualification of any option as an incentive stock option within the meaning of Section 422 of the Code. A Participant shall notify the Board in writing in the event that he disposes of Common Stock acquired upon exercise of an Incentive Stock Option within the two-year period following the date the Incentive Stock Option was granted or within the one-year period following the date he received Common Stock upon the exercise of an Incentive Stock Option and shall comply with any other requirements imposed by the Corporation in order to enable the Corporation to secure the related income tax deduction to which it will be entitled in such event under the Code.

Section 8. Extension

The Board of Directors may, in its sole discretion, extend the dates during which all or any particular Option or Options granted under the Plan may be exercised; provided, however, that no such extension shall be permitted if it would cause Incentive Stock Options issued under the Plan to fail to comply with Section 422 of the Code.

Section 9. General Provisions Applicable to Options

(a)  Each Option under the Plan shall be evidenced by a writing delivered to the Participant specifying the terms and conditions thereof and containing such other terms and conditions not inconsistent with the provisions of the Plan as the Board of Directors considers necessary or advisable to achieve the purposes of the Plan or comply with applicable tax and regulatory laws and accounting principles.

(b)  Each Option may be granted alone, in addition to or in relation to any other Option. The terms of each Option need not be identical, and the Board of Directors need not treat Participants uniformly. Except as otherwise provided by the Plan or a particular Option, any determination with respect to an Option may be made by the Board at the time of grant or at any time thereafter.

7

(c)  In the event of a consolidation, reorganization, merger or sale of all or substantially all of the assets of the Corporation in each case in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity or in the event of a liquidation of the Corporation, the Board of Directors may, in its discretion, provide for any one or more of the following actions, as to outstanding options:  (i) provide that such options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), provided that any such options substituted for Incentive Stock Options shall meet the requirements of Section 424(a) of the Code, (ii) upon written notice to the Participants, provide that all unexercised options will terminate immediately prior to the consummation of such transaction unless exercised (to the extent then exercisable) by the Participant within a specified period following the date of such notice, (iii) in the event of a merger under the terms of which holders of the Common Stock of the Corporation will receive upon consummation thereof a cash payment for each share surrendered in the merger (the “Merger Price”), make or provide for a cash payment to the Participants equal to the difference between (A) the Merger Price times the number of shares of Common Stock subject to such outstanding Options (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise price of all such outstanding Options in exchange for the termination of such Options, and (iv) provide that all or any outstanding Options shall become exercisable in full immediately prior to such event.

(d)  The Participant shall pay to the Corporation, or make provision satisfactory to the Board of Directors for payment of, any taxes required by law to be withheld in respect of Options under the Plan no later than the date of the event creating the tax liability. In the Board’s sole discretion, a Participant (other than a Participant subject to Section 16 of the Act (a “Section 16 Participant”), who shall be subject to the following sentence) may elect to have such tax obligations paid, in whole or in part, in shares of Common Stock, including shares retained from the Option creating the tax obligation. With respect to Section 16 Participants, upon the issuance of shares of Common Stock in respect of an Option, such number of shares issuable shall be reduced by the number of shares necessary to satisfy such Section 16 Participant’s federal, and where applicable, state withholding tax obligations. For withholding tax purposes, the value of the shares of Common Stock shall be the Fair Market Value on the date the withholding obligation is incurred. The Corporation may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to the Participant.

8

(e)  For purposes of the Plan, the following events shall not be deemed a termination of employment of a Participant:

(i)   a transfer to the employment of the Corporation from a subsidiary or from the Corporation to a subsidiary, or from one subsidiary to another, or

(ii)  an approved leave of absence for military service or sickness, or for any other purpose approved by the Corporation, if the Participant’s right to reemployment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Board of Directors otherwise so provides in writing.

(f)   The Board of Directors may at any time, and from time to time, amend, modify or terminate the Plan or any outstanding Option held by a Participant, including substituting therefore another Option of the same or a different type or changing the date of exercise or realization, provided that the Participant’s consent to each action shall be required unless the Board of Directors determines that the action, taking into account any related action, would not materially and adversely affect the Participant.

Section 10. Miscellaneous

(a)  No person shall have any claim or right to be granted an Option, and the grant of an Option shall not be construed as giving a Participant the right to continued employment or service on the Corporation’s Board of Directors. The Corporation expressly reserves the right at any time to dismiss a Participant free from any liability or claim under the Plan, except as expressly provided in the applicable Option.

(b)  Nothing contained in the Plan shall prevent the Corporation from adopting other or additional compensation arrangements.

(c)  Subject to the provisions of the applicable Option, no Participant shall have any rights as a shareholder (including, without limitation, any rights to receive dividends, or non cash distributions with respect to such shares) with respect to any shares of Common Stock to be distributed under the Plan until he or she becomes the holder thereof.

(d)  Notwithstanding anything to the contrary expressed in this Plan, any provisions hereof that vary from or conflict with any applicable Federal or State securities laws (including any regulations promulgated thereunder) shall be deemed to be modified to conform to and comply with such laws.

(e)  No member of the Board of Directors shall be liable for any action or determination taken or granted in good faith with respect to this Plan nor shall any member of the Board of Directors be liable for any agreement issued pursuant to this Plan or any grants under it. Each member of the Board of Directors shall be indemnified by the Corporation against any losses incurred in such administration of the Plan, unless his action constitutes serious and willful misconduct.

9

(f)   Subject to the approval of the shareholders of the Corporation, the Plan shall be effective on the date of such approval. Prior to such approval, Options may be granted under the Plan expressly subject to shareholder approval.

(g)  The Board may amend, suspend or terminate the Plan or any portion thereof at any time, provided that no amendment shall be granted without shareholder approval if such approval is necessary to comply with any applicable tax laws or regulatory requirement.

(h)  Options may not be granted under the Plan after December 31, 2025, but then outstanding Options may extend beyond such date.

(i)   To the extent that State laws shall not have been preempted by any laws of the United States, the Plan shall be construed, regulated, interpreted and administered according to the other laws of the State of New Jersey.
