                  the date of termination (the actual date of such termination
                  being referred to herein as "Date of Termination"), the
                  Employer provides Executive with written notice (the "Notice
                  of Consideration") of Employer's intent to consider
                  termination of Executive's employment for Cause, which notice
                  shall include a detailed description of the specific reasons
                  which form the basis for such consideration, and shall specify
                  a date and time for Executive to appear before the Company's
                  Board of Directors to present arguments and evidence on
                  Executive's own behalf with respect to the reasons for
                  consideration identified in the Notice of Consideration (which
                  date shall not be less than thirty (30) days after the date
                  the Notice of Consideration is provided by Employer to
                  Executive) (the "Consideration Date");

                                    (2) Executive shall have the opportunity to
                  appear before the Company's Board of Directors on the
                  Consideration Date, with or without legal representation, at

                  on Executive's own behalf with respect to such reasons for
                  consideration; and

                                    (3) Following the presentation to the
                  Company's Board of Directors as provided in Section 5.b.(2)
                  above or Executive's failure to appear before the Board of
                  Directors on the Consideration Date, Executive may be
                  terminated for Cause only if (x) the Company's Board of
                  Directors, by the affirmative vote of two-thirds (2/3) of the
                  members of a quorum of the Board of Directors present at such
                  meeting (excluding Executive if Executive is then a member of
                  the Board of Directors, and any other member of the Board of
                  Directors reasonably believed by the Board of Directors to be
                  involved in the events leading the Board of Directors to
                  terminate Executive for Cause), determines that the actions or
                  inactions of Executive specified in the Notice of Termination
                  occurred, that such actions or inactions constitute Cause; and
                  (y) the Company's Board of Directors provides Executive with a
                  written determination (a "Notice of Termination for Cause")
                  setting forth in specific detail the basis of such Termination
                  of Employment, which Notice of Termination for Cause shall be
                  consistent with the reasons set forth in the Notice of
                  Consideration. Unless the Employer establishes both (i) its
                  full compliance with the substantive and procedural
                  requirements of this Section 5.b. prior to a termination of
                  employment for Cause, and (ii) that Executive's action or
                  inaction specified in the Notice of Termination for Cause did
                  occur and constituted Cause, any termination of employment
                  shall be deemed a termination by Employer without Cause for
                  all purposes of this Agreement.

                                    (4) After providing a Notice of
                  Consideration pursuant to the provisions of Section 5.b.(1),
                  the Employer's Board of Directors may, by the affirmative vote
                  of two-thirds (2/3) of the members of a quorum of the Board of
                  Directors present at such meeting (excluding for this purpose
                  Executive if he is a member of the Board of Directors, and any
                  other member of the Board of Directors reasonably believed by
                  the Board of Directors to be involved in the events issuing
                  the Notice of Consideration), suspend Executive with pay until
                  a final determination pursuant to this Section 5.b. has been
                  made.

                                    (5) After receiving a Notice of
                  Consideration pursuant to the provisions of Section 5.b.(1),
                  Executive may terminate this Agreement without Good Reason
                  with thirty (30) days prior written notice.

                                    (6) If Executive's employment is terminated
                  under this Section 5.b., Executive shall be entitled to
                  receive accrued but unpaid compensation set forth in Section
                  3.a. and Section 3.b. hereof through the Termination Date and
                  those benefits under Section 3.d. which are required under the
                  Employee Income Retirement Security Act of 1974, as amended
                  ("ERISA"), or other applicable laws.

                           c. In the event of Executive's death or disability of
a permanent nature rendering the Executive unable to perform Executive's duties
hereunder for a period of not less than ninety (90) days during any one hundred
eighty (180) consecutive day period during the Term hereof, Employer shall pay
to the Executive or the estate of the Executive, as applicable, in the year of
death or disability, compensation which would otherwise be payable to the
Executive pursuant to Section 3 hereof up to (i) the end of the one hundred
eighty (180) day period following death, or (ii) the expiration of the one
hundred eighty (180) day period referred to above during which time the
Executive was unable to perform Executive's duties hereunder to the extent
described above.

                                    (1) The Term of employment shall end upon
                  the Executive's death or the expiration of such one hundred
                  eighty (180) day period and a determination by the Employer's
                  Board of Directors of Employer that there is no reasonable
                  accommodation (within the meaning of the Americans with
                  Disabilities Act) which would enable Executive to perform the
                  essential functions of Executive's position under this
                  Agreement despite the existence of such disability.

                                    (2) For purposes of this Agreement,
                  Executive shall be deemed to be unable to perform Executive's
                  duties hereunder when the Board of Directors of Employer, upon
                  the advice of a qualified physician mutually agreeable to the
                  Executive (or, if appropriate, Executive's representative) and
                  the Board of Directors of Employer, shall have determined that
                  Executive has become physically or mentally incapable
                  (excluding infrequent and temporary absences due to ordinary
                  illness) of performing Executive's duties under this
                  Agreement.

                                    (3) Before making any termination decision
                  pursuant to this Section 5.c., the Board of Directors of
                  Employer shall determine whether there is any reasonable
                  accommodation (within the meaning of the Americans with
                  Disabilities Act) which would enable Executive to perform the
                  essential functions of Executive's position under this
                  Agreement despite the existence of any such disability. If
                  such a reasonable accommodation is possible, Employer shall
                  make that accommodation and shall not terminate Executive's
                  employment hereunder based on such disability.

                           d. The Employer may terminate the Executive's
employment without Cause with thirty (30) days prior written notice. In that
event, the Employer shall:

                                    (1) Pay the Executive six months of Base
                  Salary, and as of the Termination Date, all accrued but unpaid
                  compensation due under Section 3.a. and Section 3.b.

                                    e. As used in this Agreement, "Cause" shall
                  mean:

                                    (1) Any embezzlement or wrongful diversion
                  of funds of Employer or any affiliate of Employer by
                  Executive;

                                    (2) Gross malfeasance by Executive in the
                  conduct of Executive's duties;

                                    (3) Material breach of this Agreement and
                  the failure to cure such breach; or
