3.1 Voluntary Resignation or Termination Without Cause. JDI may terminate Employee’s employment at any time without “Cause” (as defined in Section 3.2 hereof) upon thirty (30) days’ prior written notice to Employee. During such thirty (30) day notice period, JDI may require that Employee cease performing some or all of Employee’s duties and/or not be present at JDI’s offices and/or other facilities. Employee may voluntarily resign other than for “Good Reason” (as defined in Section 3.3(c) hereof) at any time upon sixty (60) days’ prior written notice to JDI; provided, however, JDI may, in its sole discretion, (a) advance the date of termination to any date following JDI’s receipt of such written notice and/or (b) during such sixty (60) day notice period, JDI may require that Employee cease performing some or all of Employee’s duties and/or not be present at JDI’s offices and/or facilities.

3.2 Termination for Cause. JDI may terminate Employee’s employment at any time without notice if such termination is for “Cause” (as defined herein). “Cause” means termination for any of the following reasons:

(a) Material breach of this Agreement, including a material failure to perform within the provisions of “This We Believe,” after having received prior written notice of such material breach and Employee has not corrected such material breach (if capable of correction) to the reasonable satisfaction of the Board within the thirty (30) day period following receipt by Employee of such written notice.

breach and Employee has not corrected such material breach (if capable of correction) to the reasonable satisfaction of the Board within the thirty (30) day period following receipt by Employee of such written notice.

For purposes of this Section 3.2, no act or failure to act on the part of the Employee shall be considered “willful” unless it is done, or omitted to be done, by the Employee in bad faith or without reasonable belief that the Employee’s action or omission was in the best interest of JDI.

3.3 Resignation for Good Reason, Retirement, Death, Disability or Termination without Cause.

(a) Employee’s employment shall terminate automatically and immediately upon Employee’s retirement or death.

(b) Upon the Board’s written determination that Employee is unable, due to a disability, to continue carrying out the duties and responsibilities of Employee’s position, Employee’s officer status will be terminated, and Employee’s employment will continue pursuant to JDI’s applicable policies and benefits related to disabled employees. For purposes of this Agreement, “disability” means the inability of the Employee, due to a physical or mental impairment, for 120 consecutive days to perform the essential duties and functions contemplated by this Agreement with or without reasonable accommodation. A determination of disability shall be made by an independent physician selected by the Board who is deemed satisfactory to the Employee, and Employee shall cooperate with the efforts to make such determination. Notice of determination of disability shall be provided by the Board in writing to Employee stating the facts and reasons for such determination. Any such determination shall be conclusive and binding on the parties. Nothing in this Section, however, shall be deemed to alter JDI’s duty to reasonably accommodate, if possible, any disability of Employee. Any determination of disability under this Section in not intended to affect any benefits which Employee may be entitled under any long term disability insurance policy provided by JDI or Employee with respect to Employee, which benefits shall be governed solely by the terms if any such insurance policy.

(c) Employee may resign at any time for “Good Reason” (as defined herein) without the need for sixty (60) days’ written notice to JDI. “Good Reason” shall be defined as any of the following events that have not been cured within the thirty (30) day period following the Board’s receipt of written notice of such event by Employee: (1) a material diminution in the requirements of Employee’s employment, or (2) any requirement that Employee office more than fifty (50) miles from Employee’s current principal place of employment, or (3) any material breach of the Agreement by JDI. Good Reason shall cease to exist for an event on the 90^th day following the later of the occurrence of the event or Employee’s actual knowledge thereof, unless Employee has given notice of such event on or before such 90^th day; provided further that any such event shall constitute Good Reason only if JDI fails to cure such event within thirty (30) days after receipt from Employee of written notice of the event which constitutes Good Reason and Employee actually terminates employment for such uncured Good Reason event within sixty (60) days following the expiration of such thirty (30) day cure period.

For all purposes of this Agreement, any bonus proration shall be determined on the basis of the number of days the Employee is employed in the fiscal year during which termination of employment occurs.

(c) If Employee’s employment is terminated as a result of termination without Cause or if Employee resigns for Good Reason, and so long as Employee does not materially breach any provisions of the Confidentiality Agreement, Non-Competition Agreement, Trade Secret, Invention, and Copyright Agreement and Code of Ethics and Business Conduct, respectively, in exchange for providing JDI with a legally enforceable Waiver and Release Agreement in a form reasonably satisfactory to JDI, Employee (or, in the event of his death, his estate) will receive (1) continuation of Employee’s Base Salary for two (2) years; (2) a bonus prorated at target level for the period employed during the year in which the termination occurs; (3) a bonus at the target level for the two (2) year Base Salary continuation period; (4) two (2) years of JDI sponsored medical/dental/vision care benefits for Employee and his eligible dependents (who are eligible dependents on Employee’s date of termination) at active employee contribution rates; (5) a senior executive level outplacement program by an outplacement firm selected by Employee and paid for by JDI up to $30,000, provided that such payment shall be completed not later than the 15th day of the third month following the end of the fiscal year during which the date of termination of employment occurs; (6) LTIP based upon actual LTIP cycle results occurring prorated to the date of termination of employment; (7) if permitted under the terms of JDI’s life insurance benefits plan, continued coverage for two (2) years of JDI sponsored life insurance for executives; (8) a lump sum cash payment payable within sixty (60) days following the date of termination of employment in an amount equal to the unvested value of Employee’s account balances under JDI’s Retirement Plan For Employees and the Cash Balance Supplemental Plan; and (9) one (1) year of the JDI provided Flexible Spending Account executive perquisite. Payment of Base Salary and target bonus will be paid in equal installments over the two (2) year salary continuation period. In addition to the foregoing, if Employee is terminated without Cause or Employee resigns for Good Reason prior to Employee’s five (5) year anniversary with JDI, any unvested stock and/or stock options will vest on Employee’s termination date. Moreover, Employee shall be paid Employee’s accrued but unused vacation, incurred but unreimbursed business expenses, and Employee’s accrued but unpaid performance bonus for the

5

fiscal year prior to the fiscal year during which such termination without Cause or resignation for Good Reason occurs.

(d) In addition, if Employee resigns for Good Reason or is terminated without Cause, prior to Employee’s five (5) year anniversary with JDI, JDI will relocate Employee back to the State from which Employee was originally relocated by JDI according to the terms of JDI’s relocation policy, such terms to be no less favorable than those in effect on the date of Employee’s offer of employment.

(e) If, on such date that Employee resigns for Good Reason or is terminated without Cause, Employee is covered by a JDI change-in-control plan or agreement, Employee shall receive the greater of, but not both, the payments and benefits provided under (i) the JDI change-in-control plan or agreement or (ii) Sections 3.4(c) and (d) of this Agreement.

(f) If this Agreement is not renewed by JDI beyond the Initial Term or any Renewal Term, then upon such expiration of the Agreement Employee shall be deemed to have been terminated by JDI other than for Cause.
