4.03. Confidential Information. Executive agrees that he will
not, at any time during or after the Term, make use of or divulge to any other
person, firm or corporation any trade or business secret, process, method or
means, or any other confidential information concerning the business or policies
of the Company or any of its divisions, subsidiaries or affiliates, which he may
have learned in connection with his employment hereunder. For purposes of this
Agreement, a "trade or business secret, process, method or means, or any other
confidential information" shall mean any information designated as confidential
by the Company's Board and as to which Executive receives notice, provided that
Executive shall be obligated to confer periodically with and assist the
Company's Board in determining which information should, in the best interests
of the Company, be so designated. Executive's obligation under this Section 4.03
shall not apply to any information which (i) is known publicly; (ii) is in the
public domain or hereafter enters the public domain without the fault of
Executive; (iii) is known to Executive prior to his receipt of such information
from the Company, as evidenced by written records of Executive or (iv) is
hereafter disclosed to Executive by a third party not under an obligation of
confidence to the Company. Executive agrees not to remove from the premises of
the Company, except as an employee of the Company in pursuit of the business of
the Company or except as specifically permitted in writing by the Company's
Board, any document or other object containing or reflecting any such
confidential information. Executive recognizes that all such documents and
objects, whether developed by him or by someone else, will be the sole exclusive
property of the Company. Upon termination of his employment hereunder, Executive
shall forthwith deliver to the Company all such confidential information,
including without limitation all lists of customers, correspondence, accounts,
records and any other documents or property made or held by him or under his
control in relation to the business or affairs of the Company or its
subsidiaries or affiliates, and no copy of any such confidential information
shall be retained by him.

4.04. Non-Competition Obligations. During the Term and, other
than in the case of the death or disability of Executive, upon any termination
of the employment of Executive, Executive shall not, until the earlier of (x)
two years from the date of such termination or (y) June 30, 2004 (the
"Non-Competition Period"), directly or indirectly, whether as an employee
consultant, independent contractor, partner, joint venturer or otherwise, (A)
engage in any business activities


-4-

reasonably determined by the Company's Board to be competitive, to a material
extent, with any substantial type or kind of business activities conducted by
the Company or any of its divisions, subsidiaries or affiliates at the time of
such termination; (B) on behalf of any person or entity engaged in business
activities competitive with the business activities of the Company or any of its
divisions, subsidiaries or affiliates, solicit or induce, or in any manner
attempt to solicit or induce, any person employed by, or as agent of, the
Company or any of its divisions, subsidiaries or affiliates to terminate such
person's contract of employment or agency, as the case may be, with the Company
or with any such division, subsidiary or affiliate or (C) divert, or attempt to
divert, any person, concern, or entity from doing business with the Company or
any of its divisions, subsidiaries or affiliates, nor will he attempt to induce
any such person, concern or entity to cease being a customer or supplier of the
Company or any of its divisions, subsidiaries or affiliates. The preceding
sentence notwithstanding, in the case of (i) a voluntary termination of
employment by Executive prior to a "Change in Control," or a voluntary
termination following a "Change in Control" which is not for "Good Reason" (each
as hereinafter defined), or (ii) a termination by the Company for Cause (as
hereinafter defined), the Company may elect, within 14 days after the date of
such termination, to waive Executive's non-competition obligations, in which
case it shall not be required to make payments to Executive during the
Non-Competition Period, as provided in Section 5.05(a).

4.05. Remedies. Executive acknowledges that the Company's remedy
at law for a breach by him of the provisions of this Article IV will be
inadequate. Accordingly, in the event of a breach or threatened breach by
Executive of any provision of this Article IV, the Company shall be entitled to
injunctive relief in addition to any other remedy it may have. If any of the
provisions of, or covenants contained in, this Article IV are hereafter
construed to be invalid or unenforceable in any jurisdiction, the same shall not
affect the remainder of the provisions or the enforceability thereof in any
other jurisdiction, which shall be given full effect, without regard to the
invalidity or unenforceability in such other jurisdiction. If any of the
provisions of, or covenants contained in, this Article IV are held to be
unenforceable in any jurisdiction because of the duration or geographical scope
thereof, the parties agree that the court making such determination shall have
the power to reduce the duration or geographical scope of such provision or
covenant and, in its reduced form, such provision or covenant shall be
enforceable; provided, however, that the determination of such court shall not
affect the enforceability of this Article IV in any other jurisdiction.

5.06, upon a termination of Executive's employment for any reason other than
Executive's death or disability, the Company shall continue to pay Executive
during the Non-Competition Period, his then current base salary, and an amount

by the terms and conditions of the Plan and any agreements executed by Executive
in connection with the Restricted Stock.

(c) Obligations of Executive. Executive may terminate his
employment at any time by 10 days' written notice to the Company. Executive
shall have no obligations to the Company under this Agreement after the
termination of his employment, except and to the extent Sections 4.03, 4.04 or
4.05 shall apply.

5.06. Termination Following a Change in Control. In the event
that a Change in Control occurs (as hereinafter defined) and, on or within two
years following the date of such Change in Control, Executive's employment is
terminated by the Company without Cause, or Executive terminates his employment
voluntarily for "Good Reason" (as hereinafter defined), then

(A) in lieu of the payments described in the second sentence of Section

the Restricted Stock that had not yet vested shall not vest as of the date of
such Change in Control but shall become fully vested as of the date of such
termination.

For purposes of this Agreement, "Good Reason" means

(i) any action taken or failed to be taken by the
Company or any of its officers which, without Executive's prior written
consent, changes Executive's position (including titles), authority,
duties or responsibilities from those in effect prior to the Change in
Control, or reduces Executive's ability to carry out such duties and
responsibilities;

(ii) any failure by the Company to comply with any
of the provisions of Section 3 of this Agreement,


-7-

other than an insubstantial or inadvertent failure which is remedied by
the Company promptly after receipt of notice thereof from Executive;

(iii) the Company's requiring Executive to be
employed at any location more than 35 miles further from his current
principal residence than the location at which Executive was employed
immediately preceding the Change in Control; or

(iv) any failure by the Company to obtain the
assumption of and agreement to perform this Agreement by a successor as
contemplated by Section 6.02(b) of this Agreement.

For purposes of this Agreement, "Change in Control" means the
acquisition by any individual, entity or group (within the meaning of Section
13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) (a "Person") of beneficial ownership (within the meaning of
Rule 13d-3 promulgated under the Exchange Act) of securities representing more
than 50% of the value and voting power of all of the outstanding equity
securities of Holdings (the "Outstanding Equity Securities"); provided, however,
that the following acquisitions shall not constitute a Change in Control: (i)
any acquisition by Holdings, (ii) any acquisition by one or more of the
"Investors" (as such term is defined in the Plan) or any entity directly or
indirectly controlling, controlled by, or under common control with, one or more
of the Investors (an "Investor Affiliate"), or (iii) any acquisition by a
corporation pursuant to a merger, consolidation or other similar transaction (a
"Corporate Event") if, as a result of such Corporate Event, (A) substantially
all of the individuals and entities who were the beneficial owners,
respectively, of the Outstanding Equity Securities immediately prior to such
Corporate Event beneficially own, directly or indirectly, securities
representing more than 50% of the value and voting power of the then outstanding
equity securities of the corporation resulting from such Corporate Event
(including a corporation which, as a result of such transaction, owns Holdings
or all or substantially all of Holdings' assets either directly or through one
or more subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Corporate Event, of the Outstanding Equity Securities,
and (B) no Person other than (1) one or more of the Investors or any Investor
Affiliate, or (2) any corporation resulting from such Corporate Event,
beneficially owns, directly or indirectly, securities representing more than 50%

corporation resulting from such Corporate Event.

Except as specifically provided in this Section 5.06, the effect
of a termination of Executive's employment following a


-8-

Change in Control shall be governed by the provisions of Section of 5.05.
