TERMINATION. (a) Termination for Cause. The Company has the right and may elect to terminate this Agreement for Cause. For purposes of this Agreement, "Cause" shall be limited to (i) action by the Executive involving willful malfeasance having a material adverse effect on the Company or (ii) the Executive being convicted of a felony; provided that any action by the Executive shall not constitute "Cause" if, in good faith, the Executive believed such action to be in or not opposed to the best interests of the Company, or if the Executive shall be entitled, under applicable law or the Certificate of Incorporation or Bylaws of the Company, to be indemnified with respect to such action. Termination or the Executive for Cause pursuant to this Subparagraph 6(a) shall be communicated by a Notice of Termination. For purposes of this Agreement a "Notice of Termination" shall mean delivery to the Executive of a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the directors present and voting at a meeting of the Company's Board or Directors called and held for that purpose after reasonable notice to the Executive and reasonable opportunity for the Executive, together with the Executive's counsel, to be heard before the Board prior to such vote, finding that in the good faith opinion of the Board the Executive was guilty of conduct set forth in the first sentence of this Subparagraph 6(a) and specifying the particulars thereof in detail (the date of such termination by the Board is referred hereinafter as the "Termination Date"). For purposes of this Agreement, no such purported termination of the Executive's employment shall be effective without such Notice of Termination. (b) Voluntary Resignation. Should the Executive wish to resign from his position with the Company during the term of his employment, the Executive shall give thirty (30) days written notice to the Company, setting forth the reasons and specifying the date as of which his resignation is to become effective. The date specified in such written notice shall be referenced herein as the "Termination Date." Failure to provide such notice shall entitle the Company only to fix the Termination Date as of the last business day on which the Executive reported for work at his principal place of employment with the Company and shall have no other effect. (c) Without Cause. The Company shall have the absolute right to terminate the Executive's employment without cause at any time. If the Company elects to terminate the Executive without cause, the Company shall give thirty (30) days written notice to the Executive. Thirty (30) days after such notice is given to the Executive shall be referenced herein as the "Termination Date." (d) Compensation and Benefits Upon Termination. If the employment of the Executive is terminated for any reason except (i) by the Company for Cause or (ii) by the Executive voluntarily, the Executive shall be entitled to receive, and the Company shall pay without setoff, counterclaim or other withholding except as set forth in Paragraph 4(c) the following amount (in addition to any salary, benefits or other sums due the Executive through the Termination Date) an amount equal to one-half (1/2) of his annual salary then in effect. Any amount becoming payable under this Paragraph 6(d) shall be paid on the Termination Date. 7. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. As a condition of his employment hereunder, the Executive has executed and delivered to the Company an agreement addressing the nondisclosure of confidential information (the "Nondisclosure Agreement") in the form attached hereto as Exhibit B and incorporated herein by reference as if set forth in full herein. 8. COVENANT NOT TO COMPETE. For a period beginning on the date of this Agreement and ending one (1) years after the Termination Date, the Executive will not, directly or indirectly, enter into the employment of, render services to or acquire any interest whatsoever in (whether for his own account as an individual proprietor, or as a partner, associate, shareholder, officer, director, consultant, trustee or otherwise), or otherwise assist, any person or entity engaged in any operations in North America involving any satellite digital audio radio service or any subscription-based digital audio radio service delivered to cars or other mobile vehicles; provided, however, that nothing herein shall prevent the purchase or ownership by the Executive by way of investment of up to four percent (4%) of the shares or equity interest of any corporation or other entity. Without limiting the generality of the foregoing, the Executive agrees that during the one (1) year period set forth above the Executive will not call on or otherwise solicit business or assist others to solicit business from any of the customers or potential customers of the Company as to any product or service that competes with any product or service provided or marketed by or actually under development by the Company at the time of the Executive's termination. The Executive furthermore agrees that he will not solicit or assist others to solicit the employment of or hire any employee of the Company throughout the term of this Covenant Not To Compete without the prior written consent of the Company. 9. REMEDIES. The Executive agrees that damages for breach of any of his covenants under Paragraphs 7 and 8 above will be difficult to determine and inadequate to remedy the harm which may be caused thereby, and therefore consents that these covenants may be enforced by temporary or permanent injunction without the necessity of bond. Such injunctive relief shall be in addition to and not in place of any other remedies available at law or equity. The Executive believes, as of the date of this Agreement, that the provisions of this Agreement are reasonable and that the Executive is capable of gainful employment without breaching this Agreement. However, should any court or tribunal decline to enforce any provision of Paragraph 7 or 8 of this Agreement, this Agreement shall, to the extent applicable in the circumstances before such court or tribunal, be deemed to be modified to restrict the Executive's competition with the Company to the maximum extent of time, scope and geography which the court or tribunal shall find enforceable, and such provisions shall be so enforced. The losing party shall reimburse the prevailing party for any costs and attorneys fees incurred in connection with any action to enforce the covenants under Paragraph 8 above. The Company and the Executive shall have available to them all remedies at law and in equity for the enforcement of this Agreement, which remedies (including but not limited to termination of this Agreement as provided herein) shall be cumulative and not elective. 10. INDEMNIFICATION. The Company shall indemnify the Executive to the full extent provided in the Company's Certi-ficate of Incorporation and Bylaws and the law of the State of Delaware in connection with his activities as an officer and director of the Company. 11. GOLDEN PARACHUTE PAYMENTS. If as a result of a change in control, the Executive is required to pay an excise tax on "excess parachute payments" (as defined in Section 280G(b) of the Code) under Section 4999 of the Code, the Company shall reimburse the Executive for the amount of such taxes paid. In addition, the Company shall pay the Executive such additional amounts as are necessary to place the Executive in the same financial position that she would have been in if she had not incurred any tax liability under Section 4999 of the Code as a result of such change in control; provided, however, that the Company shall in no event pay the Executive any amounts with respect to any penalties or interest due under any provision of the Code. The determination of the amount, if any, of any "excess parachute payments" and any tax liability under Section 4999 of the Code shall be made by a nationallyrecognized independent accounting firm agreed to by the Company and the Executive. The fees and expenses of such accounting firm shall be paid by the Company. The determination of such accounting firm shall be final and binding on the parties. The Company agrees to pay to the Executive any amounts to be paid or reimbursed under this Paragraph 11 within thirty (30) days after receipt by the Company of written notice from the accounting firm which sets forth such accounting firm's determination. 12. ENTIRE AGREEMENT. The provisions contained herein and the exhibits hereto constitute the entire agreement between the parties with respect to the subject matter hereof and supersede any and all prior agreements, understandings and communications between the parties, oral or written, with respect to such subject matter. 13. MODIFICATION. Any waiver, alteration, amendment or modification of any provisions of this Agreement and the exhibits hereto shall not be valid unless in writing, approved by a majority of the directors of the Company who are not fulltime employees of the Company, and signed by both the Executive and the Company. 14. SEVERABILITY. If any provision of this Agreement shall be declared to be invalid or unenforceable, in whole or in part, such invalidity or unenforceability shall not affect the remaining provisions hereof, which shall remain in full force and effect. 15. ASSIGNMENT. The Executive may not assign any of his rights or delegate any of his duties hereunder without the written consent of the Company. The Company may not assign any of its rights or delegate any of its obligations hereunder. 16. BINDING EFFECT. Subject to the limitations set forth in Paragraph 13 above, this Agreement shall be binding upon and inure to the benefit of the successors in interest of the Executive and the Company. 17. NOTICE. All notices and other communications required or permitted hereunder shall be made in writing and shall be deemed effective when initially transmitted by courier or facsimile transmission and five (5) days after mailing by registered or certified mail: (i) if to the Company: CD Radio Inc.
