(c) Decision by Employer to Terminate Without Cause.

Payment also will be made for vacation time that has accrued, but is unused as of the date of termination. (e) Benefits. In the event of Termination Without Cause, Employee -------- shall receive "Full Benefits" for nine (9) months, subject to clause (iv) below.

Notwithstanding the foregoing, Employee shall be required to pay the premiums and any other costs of such Full Benefits in the same dollar amount that he was required to pay for such costs immediately prior to Termination Without Cause. (f) Stock Options. Notwithstanding any agreement to the contrary, in ------------- the event of any other Termination Without Cause, (A) if such termination occurs more than 1 year after the date Employee commenced employment with Employer, the vesting of options to purchase shares of Employer's common stock ("Shares") granted to Employee and outstanding as of the date of Employee's termination shall be accelerated such that all such options will be vested as of the date of Employee's termination of employment with Employer; or (B) if such termination occurs on or before the first anniversary of the date Employee commenced employment with Employer, the vesting of options to purchase Shares granted to Employee and outstanding as of the date of Employee's termination and scheduled to vest during the Severance Term shall be accelerated such that all -3- such options will be vested as of the date of Employee's termination of employment with Employer.

Employee shall be ---------------------------------------------- deemed to have been terminated with Cause in the event that the employment of Employee is terminated for any of the following reasons: (a) failure (other than failure due to disability) to substantially perform his duties with Employer or an affiliate thereof; which failure remains uncured after written notice thereof and the expiration of a reasonable period of time thereafter in which Employee is diligently pursuing cure ("Failure to Perform"); -4- (b) willful conduct which is demonstrably and materially injurious to Employer or an affiliate thereof, monetarily or otherwise; (c) breach of fiduciary duty involving personal profit; or (d) willful violation in the course of performing his duties for Employer of any law, rule or regulation (other than traffic violations or misdemeanor offenses).

Payment shall also be made for accrued, but unused, vacation time. Employee shall also receive Full Benefits (as defined above) for the For Cause Term.

The adjustment referred to in clause (z) of the preceding sentence is the amount by which any tax-exempt payments referred to in clause (y) would need to be increased if such payments were subject to tax in order to make the after-tax proceeds of such payments equal to the actual amount of such tax-exempt payments. (a) Benefits. Employee shall receive Full Benefits (as defined above) for -------- one (1) year following termination due to Disability (subject to the provisions of the Split Dollar Life Insurance Agreement). (b) Stock Options. In the event that Employee's employment is terminated ------------- due to Disability, the terms of the stock option agreements between Employer and Employee shall determine the vesting of any options held by Employee as of the date of termination due to Disability and the exercise period for any vested option. -6- 5.

The terms of the stock option agreements between Employer and Employee shall determine the vesting of any options held by Employee as of the date of his death and the exercise period for any vested option. 6. Confidentiality - Employer's Obligations. Unless Employee and Employer ---------------------------------------- mutually agree on appropriate language for such purposes, in the event that Employee's employment is Terminated Without Cause or With Cause pursuant to Section 3(a) above, or Employee voluntarily resigns, Employer, except to the extent required by law, will not make or publish, without the express prior written consent of Employee, any written or oral statement concerning Employee's work related performance or the reasons or basis for the severing of Employee's employment relationship with Employer; provided, however, that the foregoing restriction is not applicable to information which was or became generally available to the public other than as a result of a disclosure by Employer. 7. Confidentiality - Employee's Obligations. Employee acknowledges and ---------------------------------------- reaffirms that Employee will comply with the terms of the confidentiality letter executed by Employee upon commencement of Employee's employment with Employer. A copy of the confidentiality letter is attached as Exhibit A. 8. Payments. Severance payments payable to Employee pursuant to the terms -------- of this Severance Agreement may be made either as a lump sum payment or pro rata on a monthly basis, at Employee's option. 9. Tax Withholding. Employer may withhold from any benefits payable under --------------- this Severance Agreement, and pay over to the appropriate authority, all federal, state, county, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling. 10. Arbitration. ----------- (a) Any controversy, claim or dispute arising out of or relating to this Severance Agreement or the breach thereof shall be settled by arbitration in accordance with the then existing Commercial Arbitration Rules of the American Arbitration Association, and judgment upon the award rendered by the arbitrator(s) may be -7- entered in any court having jurisdiction thereof. The parties irrevocably consent to the jurisdiction of the federal and state courts located in Maryland for this purpose. Each such arbitration proceeding shall be located in Maryland. (b) The arbitrator(s) may, in the course of the proceedings, order any provisional remedy or conservatory measure (including, without limitation, attachment, preliminary injunction or the deposit of specified security) that the arbitrator(s) consider to be necessary, just and equitable. The failure of a party to comply with such an interim order may, after due notice and opportunity to cure with such noncompliance, be treated by the arbitrator(s) as a default, and some or all of the claims or defenses of the defaulting party may be stricken and partial or final award entered against such party, or the arbitrator(s) may impose such lesser sanctions as the arbitrator(s) may deem appropriate. A request for interim or provisional relief by a party to a court shall not be deemed incompatible with the agreement to arbitrate or a waiver of that agreement. (c) The parties acknowledge that any remedy at law for breach of this Severance Agreement may be inadequate, and that, in the event of a breach by Employee of Section 7, any remedy at law would be inadequate in that such breach would cause irreparable competitive harm to Employer. Consequently, in addition to any other relief that may be available, the arbitrator(s) also may order permanent injunctive relief, including, without limitation, specific performance, without the necessity of the prevailing party proving actual damages and without regard to the adequacy of any remedy at law. (d) In the event that Employee is the prevailing party in such arbitration, then Employee shall be entitled to reimbursement by Employer for all reasonable legal and other professional fees and expenses incurred by him in such arbitration or in enforcing the award, including reasonable attorney's fees. (e) The parties agree that the results of any such arbitration proceeding shall be conclusive and binding upon them. 11. Continued Employment. This Severance Agreement shall not confer upon -------------------- the Employee any right with respect to continuance of employment by Employer. -8- 12. Mitigation. Employee shall not be required to mitigate the amount of ---------- any payment, benefit or other Trust obligation provided for in this Severance Agreement by seeking other employment or otherwise and no such payment shall be offset or reduced by the amount of any compensation or benefits provided to Employee in any subsequent employment. 13. Grant of January 2, 1998 Options.

Except as provided in the preceding sentence, no action taken pursuant to this Severance Agreement shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained herein. The waiver by any party hereto of a breach of any provision of this Severance Agreement shall not operate or be construed as a waiver of any preceding or succeeding breach. No failure by either party to exercise any right or privilege hereunder shall be deemed a waiver of such party's rights to exercise the same any subsequent time or times hereunder. 17. Severability. In case any one or more of the provisions of this ------------ Severance Agreement shall, for any reason, be held or found by determination of the arbitrator(s) pursuant to an arbitration held in accordance with Section 10 above to be invalid, illegal or unenforceable in any respect (i) such invalidity, illegality or unenforceability shall not affect any other provisions of this Severance Agreement, (ii) this Severance Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. Failure to insist upon strict compliance with any provision of this -9- Severance Agreement shall not be deemed a waiver of such provision or of any other provision of this Severance Agreement. 18. Governing Law.
