Company.

the Company or its affiliates;

                           (iii)       material breach of Executive’s
obligations under this Agreement;

3

        4.4    Termination without Cause.

                   (a)       If Executive’s employment is terminated by the
Company prior to the end of the Term for any reason other than Cause or the
death or disability of Executive:

pay Executive all of the compensation provided for in Sections 3.1 and 3.2
herein (based on not less than the previous year’s bonus and prorated to the end

so requests in writing, pay Executive in a lump sum upon such termination the
present value of the payments that would have been made under clause (A), using
a discount rate of 6 percent per year;

                           (ii)       Executive shall be entitled continue to
receive medical benefits coverage in accordance with the Company’s policies in
effect from time to time through the remainder of the then-current Term;

--------------------------------------------------------------------------------

make any payments under this Section 4.4 unless Executive shall have executed
and delivered to the Company a further agreement, to be prepared at the time of
Executive’s termination of employment, that shall provide (i) an unconditional
release of all claims (other than claims under Section 4.4(a)) charges,
complaints and grievances, whether known or unknown to Executive, against the
Company or any of its affiliates, through date of Executive’s termination of
employment; (ii) an undertaking to maintain the confidentiality of such
agreement; and (iii) an undertaking to indemnify the Company if Executive

Agreement”). If Executive becomes entitled to any payment by the terms of the
Change-of-Control Agreement, he shall not be entitled to any additional payment
under this Agreement (other than accrued and unpaid bonus, salary and benefits),
but the provisions of Section 4.4(a)(ii) through (iv) or Section 4.5(i) and
(ii), as the case may be, will apply.

        4.7    Stock Options.    If Executive’s employment is terminated by the
Company during the Term for any reason other than for Cause or if Executive
terminates his employment during the Term under circumstances that would
constitute an Involuntary Termination as defined in the Change-of-Control
Agreement, then any stock options granted to Executive by the Company which have
not been exercised by Executive prior to Executive’s termination shall
accelerate and be exercisable in full and may be exercised by Executive or his
legal representative, estate, personal representative or beneficiary who
acquired the right to exercise such options by bequest or inheritance, as the
case may be, to the extent provided by the terms of the Company’s Stock Option
Plan or any option agreement.

--------------------------------------------------------------------------------

SECTION 5.   RESTRICTIVE COVENANTS.

        5.1    Confidentiality.    Executive acknowledges a duty of
confidentiality owed to the Company and shall not, at any time during or after
his employment by the Company, retain in writing, use, divulge, furnish, or make
accessible to any person or entity, without the express authorization of the
Board of Directors of the Company, any trade secret, private or confidential
information or knowledge of the Company obtained or acquired by him while so
employed. All computer software, address books, rolodexes, business cards,
telephone lists, customer lists, price lists, contract forms, catalogs, books,
records, files and know-how acquired while an employee of the Company are
acknowledged to be the property of the Company and shall not be duplicated,
removed from the Company’s possession or premises or used other than in pursuit
of the Company’s business and, upon termination of employment for any reason,
Executive shall deliver to the Company, without further demand, all copies and
summaries thereof (whether in written, electronic or other form) which are then
in his possession or under his control.

        5.2    Inventions and Improvements.    Executive shall promptly
communicate to the Company all ideas, discoveries, inventions and business
opportunities which are or may be useful to the Company or its business.
Executive acknowledges that all such ideas, discoveries, inventions, and
improvements which heretofore have been or are hereafter made, conceived, or
reduced to practice by him at any time during his employment with the Company
and every item of knowledge relating to the Company’s business interests
(including business opportunities) heretofore or hereafter gained by him at any
time during his employment with the Company are the property of the Company, and
Executive hereby irrevocably assigns all such ideas, discoveries, inventions,
improvements, and knowledge to the Company for its sole use and benefit, without
additional compensation. The provisions of this Section 5.2 shall apply whether
such ideas, discoveries, inventions, improvements or knowledge were or are
conceived, made or gained by him alone or with others, whether during or after
usual working hours, whether on or off the job, whether applicable to matters
directly or indirectly related to the Company’s business interests (including
potential business interests), and whether or not within the specific realm of
his duties. It shall be conclusively presumed that ideas, discoveries,
inventions, and improvements relating to the Company’s business interests or
potential business interests conceived by Executive during the six month period
following termination of his employment are, for the purposes of this Agreement,
conceived prior to termination of his employment hereunder. Executive shall,
upon request of the Company, but at no expense to Executive, at any time during
or after his employment with the Company, sign all instruments and documents
reasonably requested by the Company and otherwise cooperate with the Company to
protect its right to such ideas, discoveries, inventions, improvements, and
knowledge, including applying for, obtaining, and enforcing patents and
copyrights thereon in such countries as the Company shall determine.

        5.3    Noncompetition.    During the term of Executive’s employment and
for one year after any termination of employment, or, if longer, for so long as
Executive is entitled to the payment of amounts pursuant to Section 4.4(a)
herein following a termination by the Company without Cause or pursuant to the
Change-in-Control Agreement, Executive shall not directly or indirectly: (i)
engage, anywhere in any geographic market served by the Company or any of its
subsidiaries in any activity which competes in whole or in part with the
products or activities of the Company at the time of such termination; (ii) be
or become a stockholder, partner, owner,

6

--------------------------------------------------------------------------------

officer, director or employee or agent of, or a consultant to or give financial
or other assistance to, any person or entity engaged in any such activities;
(iii) seek in competition with the business of the Company to procure orders
from or do business with any customer of the Company; (iv) solicit, or contact
with a view to, the engagement or employment by any person or entity of any
person who is an employee of the Company; (v) seek to contract with or engage
(in such a way as to adversely affect or interfere with the business of the
Company) any person or entity which has been contracted with or engaged to
manufacture, assemble, supply or deliver products, goods, materials or services
to the Company; or (vi) engage in or participate in any effort or act to induce
any of the customers, associates, consultants, or employees of the Company to
take any action which might be disadvantageous to the Company; provided,
however, that nothing herein shall prohibit Executive and his affiliates from
owning, as passive investors, in the aggregate not more than 5% of the
outstanding publicly traded stock of any corporation so engaged. The duration of
Executive’s covenants set forth in this Section shall be extended by a period of
time equal to the number of days, if any, during which Executive is in violation
of the provisions hereof.

        5.4    Injunctive and Other Relief.

                   (a)       Executive acknowledges and agrees that the
covenants contained herein are fair and reasonable in light of the consideration
paid hereunder, and that damages alone shall not be an adequate remedy for any
breach by Executive of his covenants contained herein and accordingly expressly
agrees that, in addition to any other remedies which the Company may have, the
Company shall be entitled to injunctive or other equitable relief in any court
of competent jurisdiction for any breach or threatened breach of any such
covenants by Executive. Nothing contained herein shall prevent or delay the
Company from seeking, in any court of competent jurisdiction, specific
performance or other equitable remedies in the event of any breach or intended
breach by Executive of any of his obligations hereunder.

                   (b)       Notwithstanding the equitable relief available to
the Company, Executive, in the event of a breach of his covenants contained in
Section 5 herein, understands and agrees that the uncertainties and delay
inherent in the legal process would result in a continuing breach for some
period of time, and therefore, continuing injury to the Company until and unless
the Company can obtain such equitable relief. Therefore, in addition to such
equitable relief, the Company shall be entitled to monetary damages for any such
period of breach until the termination of such breach, in an amount deemed
reasonable to cover all actual and consequential losses, plus all monies
received by Executive as a result of said breach and all costs and attorneys’
fees incurred by the Company in enforcing this Agreement. If Executive should
use or reveal to any other person or entity any confidential information, such
use or revelation would be considered a continuing violation on a daily basis,
for as long as such confidential information is made use of by Executive or any
such other person or entity.

                   (c)       If any provision of Section 5 herein is determined
to be invalid or unenforceable by reason of its duration or scope, such duration
or scope, or both, shall be deemed to be reduced to a duration or scope to the
extent necessary to render such provision valid and enforceable. In such event,
Executive shall negotiate in good faith to provide the Company with lawful and
enforceable protection that is most nearly equivalent to that found to

7

--------------------------------------------------------------------------------

be invalid or unenforceable.

                   (d)       The existence of any claim or cause of action that
Executive or any other person or entity may have against the Company shall not
constitute a defense or bar to the enforcement of any of the provisions of this
Section 5.

        5.5    Definition of the “Company.”    The “Company” as used in this
Section 5 includes all affiliates and subsidiaries of the Company.

SECTION 6.   MISCELLANEOUS

        6.1    Litigation.    At the request of the Company, Executive shall
during and after the Term render reasonable assistance to the Company in
connection with any litigation or other proceeding involving the Company or any
of its affiliates. The Company will pay Executive reasonable compensation as
mutually agreed for any such services performed after the Term. The Company
agrees that during the Term that at all times it shall carry appropriate amounts
of officers and directors liability insurance naming the Executive as an insured
party.

        6.2    Arbitration.    All claims and disputes relating to this
Agreement or concerning Executive’s employment or termination shall be
conclusively resolved by arbitration in Philadelphia, Pennsylvania, under the
then existing rules of the American Arbitration Association. Judgment upon any
award rendered may be entered by either party in any court of competent
jurisdiction. The cost of such arbitration shall be borne equally by the parties
or as otherwise directed by the arbitrators. This Section 6.2 shall not limit
the right of the Company to seek judicial relief pursuant to Section 5.4 herein
without prior arbitration.

        6.3    Assignment; Benefit.    This Agreement shall not be assignable by
Executive, and shall be assignable by the Company only to any affiliate or to
any person or entity which may become a successor in interest (by purchase of
assets or stock, or by merger, or otherwise) to the Company in the business or
substantially all of the business presently operated by it. Subject to the
foregoing, this Agreement and the rights and obligations set forth herein shall
inure to the benefit of, and be binding upon, the parties hereto and each of
their respective permitted successors, assigns, heirs, executors and
administrators.

requested or by telegram or telefax (confirmed by U.S. mail), receipt
acknowledged, addressed as set forth below or to such other person and/or at

other. Any such notice shall be deemed to have been given as of the date
received, in the case of personal delivery, or on the date shown on the receipt
or confirmation therefor, in all other cases. Any and all service of process and
any other notice in any action, suit or proceeding-shall be effective against
any party if given as provided in this Agreement; provided that nothing herein

manner permitted by law.
