                     (f) INTERNAL REVENUE CODE SECTION 280G. Notwithstanding
anything contained in this Agreement to the contrary, to the extent that any
payment or distribution of any type to or for the benefit of the Executive by
the Company, any affiliate of the Company, any person who acquires ownership
or effective control of the Company or ownership of a substantial portion of
the Company's assets (within the meaning of Section 280G of the Internal
Revenue Code (the "Code"), and the regulations thereunder), or any affiliate
of such person, whether paid or payable or distributed or distributable
pursuant to the terms of this Agreement or otherwise (the "Total Payments")
is or will be subject to the excise tax imposed under Section 4999 of the
Code (the "Excise Tax"), then the Total Payments shall be reduced (but not
below zero) if and to the extent that a reduction in the Total Payments would
result in the Executive retaining a larger amount, on an after-tax basis
(taking into account federal, state and local income taxes and the Excise
Tax), than if the Employee received the entire amount of such Total Payments.
Unless the Executive shall have given prior written notice specifying a
different order to the Company to effectuate the foregoing, the Company shall
reduce or eliminate the Total Payments, by first reducing or eliminating the
portion of the Total Payments which are not payable in cash (other than Total
Payments attributable to stock options or other equity awards ("EQUITY
AWARDS")) and then by reducing or eliminating cash payments, in each case in
reverse order beginning with payments or benefits which are to be paid the
latest in time, and then by reducing Equity Awards in the manner which


                                     -4-
<PAGE>

will maximize the after-tax benefit to the Executive. Any notice given by the
Executive pursuant to the preceding sentence shall take precedence over the
provisions of any other plan, arrangement or agreement governing the
Executive's rights and entitlements to any benefits or compensation. The
determination of whether the Total Payments shall be reduced pursuant to the
foregoing and the amount of such reduction shall be made, at the Company's
expense, by an accounting firm selected by the Company which is one of the
five largest accounting firms in the United States (other than the Company's
regular independent auditor).

                     (g) For purposes of this SECTION 5, the Executive's
employment shall not be treated as terminated for so long as he is an
employee of the Company or any of its subsidiaries.

                  6. EXECUTIVE COVENANTS.

                     (a) UNAUTHORIZED DISCLOSURE. The Executive agrees and
understands that in the Executive's position with the Company, the Executive
has been and will be exposed to and has and will receive information relating
to the confidential affairs of the Company, its subsidiaries and affiliates,
including but not limited to technical information, intellectual property,
business and marketing plans, strategies, customer information, other
information concerning the products, promotions, development, financing,
expansion plans, business policies and practices of the Company, its
subsidiaries and affiliates, and other forms of information considered by the
Company to be confidential and in the nature of trade secrets ("Confidential
Information"). The Executive agrees that during the Employment Term and
thereafter, the Executive will not disclose such Confidential Information,
either directly or indirectly, to any third person or entity without the prior
written consent of the Company. This confidentiality covenant has no temporal,
geographical or territorial restriction. Upon termination of the Employment
Term, the Executive will promptly supply to the Company, within reasonable
limitations, all property, keys, notes, memoranda, writings, lists, files,
reports, customer lists, correspondence, tapes, disks, cards, surveys, maps,
logs, machines, technical data or any other tangible product or document which
has been produced by, received by or otherwise submitted to the Executive during
or prior to the Employment Term. Any material breach of the terms of this
paragraph shall be considered Cause.

                     (b) NON-COMPETITION. By and in consideration of the
Company's entering into this Agreement and the payments to be made and benefits
to be provided by the Company hereunder, and further in consideration of the
Executive's exposure to the proprietary information of the Company, the
Executive agrees that the Executive will not, during the Employment Term, and
thereafter during the "Non-competition Term" (as defined below), directly or
indirectly, own, manage, operate, join, control, be employed by, or participate
in the ownership, management, operation or control of, or be connected in any
manner with, including but not limited to holding any position as a shareholder,


                                     -5-
<PAGE>

director, officer, consultant, independent contractor, employee, partner, or
investor in, any "Restricted Enterprise" (as defined below); PROVIDED, that in
no event shall the ownership of less than 1% of the outstanding equity
securities of any issuer whose securities are registered under the Securities
and Exchange Act of 1934, as amended, standing alone, be prohibited by this
SECTION 6(b). For purposes of this SECTION 6(b), the term "RESTRICTED
ENTERPRISE" shall mean any person, corporation, partnership or other entity that
competes, directly or indirectly, with any business or activity conducted or
proposed to be conducted by the Company or any of its subsidiaries or affiliates
as of the date of the Executive's termination of employment. Following
termination of the Employment Term, upon request of the Company, the Executive
shall notify the Company of the Executive's then current employment status. For
purposes of this Agreement, the "NON-COMPETITION TERM" shall mean the period
beginning on the Termination Date and ending on the second anniversary of such
date. Any material breach of the terms of this SECTION 6(b) shall be considered
Cause. Notwithstanding the foregoing, in the event the Executive's employment
with the Company is terminated following a Change in Control by the Company
without Cause or by the Executive for Good Reason, the Executive shall not be
subject to this SECTION 6(b), and this SECTION 6(b) shall have no force or
effect.

                     (c) NON-SOLICITATION. During the Non-competition Term, the
Executive shall not, and shall not cause any other person to, interfere with or
harm, or attempt to interfere with or harm, the relationship of the Company, any
of its subsidiaries or affiliates with, or endeavor to entice away from the
Company, any of its subsidiaries or affiliates, or hire, any person who at any
time during the Employment Term was an employee or customer of the Company, or
any of its subsidiaries or affiliates. Notwithstanding the foregoing, in the
event the Executive's employment with the Company is terminated following a
Change in Control by the Company without Cause or by the Executive for Good
Reason, the Executive shall not be subject to this SECTION 6(c), and this
SECTION 6(c) shall have no force or effect.

                     (d) REMEDIES. The Executive agrees that any breach of the
terms of this SECTION 6 would result in irreparable injury and damage to the
Company, its subsidiaries and/or affiliates for which the Company, its
subsidiaries and/or affiliates would have no adequate remedy at law; the
Executive therefore also agrees that in the event of said breach or any threat
of breach, the Company, its subsidiaries and/or affiliates, as applicable, shall
be entitled to an immediate injunction and restraining order to prevent such
breach and/or threatened breach and/or continued breach by the Executive and/or
any and all persons and/or entities acting for and/or with the Executive,
without having to prove damages, in addition to any other remedies to which the
Company, its subsidiaries and/or affiliates may be entitled at law or in equity.
The terms of this SECTION 6(d) shall not prevent the Company, its subsidiaries
and/or affiliates from pursuing any other available remedies for any breach or
threatened breach hereof, including but not limited to the recovery of damages
from the Executive. The Executive and the Company


                                     -6-
<PAGE>

further agree that the provisions of the covenants contained in this SECTION 6
are reasonable and necessary to protect the businesses of the Company, its
subsidiaries and affiliates because of the Executive's access to Confidential
Information and his material participation in the operation of such businesses.
The Executive hereby acknowledges that due to the global aspects of the
Company's, its subsidiaries' and affiliates' businesses and competitors it would
not be appropriate to include any geographic limitation on this SECTION 6.
Should a court or arbitrator determine, however, that any provision of the
covenants contained in this SECTION 6 are not reasonable or valid, either in
period of time, geographical area, or otherwise, the parties hereto agree that
such covenants should be interpreted and enforced to the maximum extent which
such court or arbitrator deems reasonable or valid.

                  The existence of any claim or cause of action by the Executive
against the Company, its subsidiaries and/or affiliates, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of the covenants contained in this SECTION 6.

                  7. NON-WAIVER OF RIGHTS. The failure to enforce at any time
the provisions of this Agreement or to require at any time performance by any
other party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to affect either the validity of this Agreement or
any part hereof, or the right of any party to enforce each and every provision
in accordance with its terms.

                  8. NOTICES. Every notice relating to this Agreement shall be

Beneficially Owned, directly or indirectly, by a Parent Corporation;

                         (ii) A complete liquidation or dissolution of the
Company; or

                         (iii) The sale or other disposition of all or
substantially all of the assets of the Company to any Person (other than a
transfer to a Related Entity or under conditions that would constitute a
Non-Control Transaction with the disposition of assets being regarded as a
Merger for this purpose or the distribution to the Company's stockholders of the
stock of a Related Entity or any other assets).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person (the "Subject Person") acquired Beneficial Ownership
of more than the permitted amount of the then outstanding Common Stock or Voting
Securities as a result of the acquisition of Common Stock or Voting Securities
by the Company which, by reducing the number of Common Stock or Voting
Securities then outstanding, increases the proportional number of shares
Beneficially Owned by the Subject Persons, provided that if a Change in Control
would occur (but for the operation of this sentence) as a result of the
acquisition of Common Stock or Voting Securities by the Company, and after such
share acquisition by the Company, the Subject Person becomes the Beneficial
Owner of any additional Common Stock or Voting Securities which increases the
percentage of the then outstanding Common Stock or Voting Securities
Beneficially Owned by the Subject Person, then a Change in Control shall occur.

                  "DISABILITY" shall mean the inability of the Executive to
perform his duties, services and responsibilities hereunder by reason of a
physical or mental infirmity, as reasonably determined by the Board, for a total
of 180 calendar days in any twelve-month period during the Employment Term.

                  "GOOD REASON" shall mean after a Change in Control, the
occurrence of any of the following events: (i) a material diminution in the
Executive's position, duties or responsibilities; (ii) a reduction in the
Executive's Base Salary; or (iii) a relocation of the Company's corporate
headquarters to a location that is more than 50 miles from the location of the
corporate headquarters immediately before the Change in Control.

                  "PRO RATA BONUS AMOUNT" shall mean an amount equal to the
annual bonus paid to the Executive for the year prior to the year in which the
Executive's employment is terminated, multiplied by a fraction, the numerator of
which is the number of days elapsed from the beginning of the bonus period
through and including the Termination Date, and the denominator of which is 365.
