The Employee will perform faithfully his duties and responsibilities hereunder.

ARTICLE II

Term and Termination

2.1 Term. Employee’s employment under this Agreement shall commence on February 1 2006, shall be at will, and may be terminated by formal or informal action of the Chairman or the Employee at any time for any reason not prohibited by law.

2.2 Resignation or Termination for Cause. If Employee should resign Employee’s employment without Good Reason (defined below), or if the Chairman should terminate Employee’s employment for Cause (defined below), Employee shall not be entitled to any compensation or remuneration other than all earned and unpaid salary, unused vacation, unreimbursed business expenses, and such amounts and benefits as Employee is eligible to receive under JDI’s then prevailing policies and benefit plans and as prescribed by law. “Good Reason” means JDI’s material breach of any provision of this Agreement. “Cause” means termination for any of the following reasons:

(a) Material breach of this Agreement.

(b) Material failure to perform within the provisions of “This We Believe.”

(c) Gross misconduct, or willful violation of the law in the performance of duties under this Agreement.

(d) Willful failure or refusal to follow reasonable, explicit, and lawful instructions or directions from the Chairman concerning the operation of JDI’s business.

(e) Conviction of a felony.

A determination of disability shall be made by an independent physician selected by the Chairman who is satisfactory to the Employee, and Employee shall cooperate with the efforts to make such determination.

(c) If Employee’s employment is terminated as a result of Death, JDI shall pay to Employee’s estate, in addition to all earned and unpaid salary, unused vacation, unreimbursed business expenses, and any other compensation and benefits provided by JDI policies and benefit plans then in effect, (1) a prorated performance bonus for the fiscal year in which the termination occurs, as described in Section 3.2, which shall be payable at the time and in the manner in which JDI normally pays such bonuses; and (2) reimbursement of expenses to which Employee is entitled under Section 3.6.

(d) If Employee’s employment is terminated as a result of Termination without Cause or Resignation with Good Reason, and so long as Employee complies with all provisions of the Agreement to Respect Proprietary Rights and Noncompete and Code of Ethics, attached as Addenda A and B, respectively, JDI shall, in addition to paying Employee all earned and unpaid salary, unused vacation, unreimbursed business expenses, and any other compensation and benefits due him under JDI policies and benefit plans then in effect, (1) continue to pay Employee his base salary for and during the two-year period beginning on the day immediately following the date of such termination (“Salary Continuation Period”); (2) pay Employee a prorated performance bonus for the period worked during the fiscal year in which the termination occurs, as described in Section 3.2; and (3) pay Employee a performance bonus at the target level (currently 100% of Base Salary) for each year during the Salary Continuation Period.
