         WHEREAS, the Executive and the Company are parties to an Employment
Agreement dated as of October 2, 2001 (the "Employment Agreement");

         WHEREAS, the Executive has agreed to resign from his employment with
the Company and relinquish his position as Chief Executive Officer of the

         WHEREAS, the Executive desires to assist the Company in effecting an
orderly and efficient transition in respect of the Company's senior management
following the Effective Date; and

         WHEREAS, the Executive and the Company desire to set forth their
understanding of the Executive's role during the Transition Period (as
hereinafter defined) and the parties rights and obligations resulting from the
Executive ceasing to be employed by the Company as of the Effective Date.

         NOW, THEREFORE, in consideration of the mutual agreements and

Effective as of the end of the Transition Period, the Executive shall resign
from his position as a member of the Board and from his position as the Chairman
of the Board, including all duties and responsibilities associated with such

                                       1


         (b) Removal of Personal Property. In no event later than May 31, 2002,

after May 31, 2002, the Executive shall not maintain an office or presence at
the Company's corporate offices, including but not limited to the corporate

         (c) Payments and Benefits. In consideration for the Executive's

Executive shall be entitled to receive from the Company the payments and
benefits set forth in subparagraphs (i) through (iv) of this Section 1(c),
provided that the Executive shall not have revoked such Release:

                  (i) on the eighth day after the Executive's execution of this
Agreement, to the extent there has been no revocation of the Release by the
Executive prior to such date (the "Payment Date"), the Company shall pay the
Executive in a lump sum in cash any accrued and unpaid base salary, bonuses or
deferred compensation in respect of periods through the Effective Date;
provided, however, that, to the extent permitted under the terms of the
Company's Deferred Compensation Plan, the Executive shall be entitled to defer
payment of up to $2,528,834 of such deferred compensation until no later than
January 1, 2003;

                  (ii) on the Payment Date, the Company shall pay the Executive
a lump sum in cash in an amount equal to $5,525,000, less applicable
withholding, of which (1) $5,100,000 represents the severance pay the Executive
would have been entitled under Section 7.4 of the Employment Agreement as if his
employment had been terminated by the Company without "Cause" (as such term is
defined in the Employment Agreement) on the Effective Date and (2) $425,000
represents the Executive's incentive compensation bonus with respect to the
fiscal year of the Company during which the Effective Date occurs;

                  (iii) for a period of two years beginning on the Payment Date,
the Company will continue to provide, on the same basis as executive officers of
the Company generally, the health and life insurance benefits (but excluding
disability benefits) provided to the Executive and his spouse and eligible
dependants immediately prior to the Payment Date (provided that the Executive
continues to make all required employee contributions). In the event that the
Executive's participation in any such plan or program is barred by the terms
thereof, the Company shall pay to the Executive an amount equal to the annual
contribution, payments, credits or allocation made by the Company to him, to his
account or on his behalf under such plans and programs from which his continued
participation is barred except that if the Executive's participation in any
health, medical or life insurance plan or program is barred, the Company shall
obtain and pay for, on the Executive's behalf, individual insurance plans,
policies or programs that provide to the Executive's health, medical and life
insurance coverage which is equivalent to the insurance coverage to which the
Executive was entitled prior to the Payment Date;

                                       2


                  (iv) for a period of two years beginning on the Payment Date,

entitled to receive the then cash value of such policy less the aggregate amount
of premiums paid by the Company on such policy;

                  (v) the Executive's outstanding deferred stock grant of
150,000 shares of the common stock of the Company shall fully vest as of the
Payment Date and, to the extent permitted by the terms of the Company's Deferred
Compensation Plan, the Executive shall be entitled to defer receipt of such
shares until no later than January 1, 2003; and

225,000 shares of the common stock of the Company shall fully vest as of the
Payment Date, shall remain exercisable for a period of ninety (90) days
following the Effective Date and shall thereafter terminate to the extent
unexercised by the Executive; provided, however, that in no event will such
stock options be exercisable following the expiration of the term of such stock
options.

         Section 2. Consulting Services During the Transition Period. During the
Transition Period, the Executive shall serve as a consultant to the Company and
shall perform such consulting services as the Board and/or the Interim Chief
Executive Officer of the Company shall reasonably request to assist the Company
in effecting an orderly and efficient transition in respect of the Company's
senior management. Effective as of the end of the Transition Period, the
Executive shall cease to be a consultant of the Company. During the Transition
Period, the Company shall pay the Executive a consulting fee of $70,833.33 per
month, payable at the end of each month during the Transition Period. During the
Transition Period, the Company shall, upon proper submission of proper vouchers
in respect thereof, pay or reimburse the Executive in accordance with the
Company's reimbursement and expense policies, as in effect from time to time,
for all reasonable expenses incurred by the Executive in performing consulting
services for the Company, provided that in no event shall any such payment or
reimbursement exceed $6,000 in any month during the Transition Period. During
the Transition Period, the Company shall provide the Executive an office, at a
location separate from the Company's corporate offices, and secretarial services
that are substantially comparable to the office and secretarial services
provided to the Executive immediately prior to the Effective Date.

policy, agreement, understanding or promise, whether written or oral, formal or
informal, between any of the Releasees and the Executive.

                  (b) Nothing herein shall be deemed to release (i) any of the
Executive's rights under this Agreement, (ii) any of the Executive's rights that
have accrued prior to the date hereof under the Company's employee benefit
plans; or (iii) any of the Executive's rights to indemnification under any

                  (c) The Executive represents that the Company has advised him
to consult with an attorney of his choosing prior to signing this Agreement. The
Executive further represents that he understands and agrees that he has the
right and has in fact reviewed this Agreement and, specifically, the Release,
with an attorney of the Executive's choice. The Executive further represents
that he understands and agrees that the Company is under no obligation to offer
him this Agreement, and that the Executive is under no obligation to consent to
the Release, and that he has entered into this Agreement freely and voluntarily.


                  (d) The Executive shall have twenty-one (21) days to consider

remedies it might have under the law which are reserved, to obtain injunctive
relief to restrain any breach or threatened breach by the Executive of this

Section 11.2 of the Employment Agreement shall be enforceable by the Company for
a period of one year following the Effective Date and shall thereafter
terminate.

                  (d) Severability. If any term or other provision of this

more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.
